Abstract
OBJECTIVE Although medication adherence (MA) contributes to therapeutic outcome in systemic sclerosis (SSc), research data are scarce. Factors influencing MA in SSc are hardly known. METHOD We conducted a monocentric, cross-sectional study on 85 patients with SSc at the University of Lübeck, Germany, using the Compliance Questionnaire of Rheumatology as the main measurement tool of MA. We also used the Scleroderma Health Assessment Questionnaire, Illness Perception Questionnaire - Revised, Health Literacy Questionnaire, Lübeck Medication Satisfaction Questionnaire (a novel instrument created for this study), and patients' demographic and clinical data, to find factors contributing to MA. RESULTS Good MA was seen in 51.8% of patients. MA was positively associated with therapy satisfaction (p < 0.001), modified Rodnan Skin Score (p = 0.032), age (p = 0.025), intake of micronutrients (p = 0.033), number of prescribed drugs (p = 0.014), and some dimensions of health literacy. Negative associations were found for patients with weight loss attributed to SSc (p = 0.009) and the perception that the disease is caused by the patient's personality (p = 0.011) or emotional state (p = 0.037). CONCLUSION Although most SSc patients display good MA, non-adherence remains a major problem. Patients should be assessed for non-adherence. The factors affecting MA identified herein could help to improve therapeutic outcomes.

Abstract
BackgroundIn SSc, autoantibodies (abs) directed against G protein-coupled receptors (GPCR) are prominent and for example induce release of inflammatory and profibrotic proteins by monocytes (1-3). Increased levels of autoantibodies against angiotensin II type 1 receptor (AT1R abs) have been found in patients with renal involvement in systemic sclerosis (SSc) (4-5). The elevated amount of anti-GPCR abs is accompanied by increased secretion of extracellular vesicles (EVs) in SSc (6). The importance of EVs in the pathogenesis is also based on packing and horizontal transfer of AT1R to different tissues and immune cells, exemplary shown by activated cardiomyocytes leading to higher responsiveness to Angiotensin II of recipient cells and vessels (7). Taken together, the relevance of studying anti-GPCR abs together with GPCR-EVs in SSc pathogenesis becomes evident (8). Interestingly, CCL18 is found to be upregulated in SSc patients and suggested to be upregulated by AT1R abs (9), indicating CCL18 and CCR8 cross-talk via EVs plays an essential role in the pathogenesis of SSc.ObjectivesUnravel the immune response of peripheral blood monocytes mediated by anti-AT1R abs and EVs to gain new insights into the pathomechanism in SSc.MethodsHuman peripheral blood monocytes of healthy donors were stimulated by the endogenous AT1R ligand angiotensin II as well as by a monoclonal anti-human AT1R ab and, in comparison, by purified IgG from HD (HD IgG) versus those from SSc (SSc IgG). Further, human peripheral blood monocytes of HD were treated with EVs derived from sera of SSc patients versus sera of HD, in the presence or absence of a monoclonal recombinant anti-AT1R ab. Monoclonal AT1R ab has been generated by hybridoma technique, sequenced and recombinantly expressed in HEK cells. The specificity of AT1R abs was tested by using an AT1R blocker (telmisartan, TEL). EVs were isolated from sera by differential centrifugation to exclude large particles and microvesicles and further by one-step polymer precipitation procedure utilising ExoQuick Exosome Precipitation Solution (System Biosciences, Palo Alto, CA) and subsequent purification by size exclusion. Further, primary human peripheral blood monocytes of HD (n=6) were treated with EVs derived from sera of SSc patients (n=6) versus sera of HD (n=6), in the presence or absence of a monoclonal recombinant anti-AT1R ab. The response of the monocytes was measured via CCL18 secretion by ELISA.ResultsThe recombinant monoclonal anti-human AT1R antibody induced secretion of CCL18, a profibrotic cytokine, by primary monocytes derived from HD. Similarly, the purified IgG fractions derived from SSc patients also induced an increased CCL18 release by monocytes compared to IgG fractions derived from HD. Further, complete amelioration of the AT1R ab effect on CCL18 secretion was found, when monocytic AT1R expression was blocked with TEL. In addition, antagonistic effects of Angiotensin II to the monoclonal AT1R ab were observed. In line, enhanced CCL18 secretion of human monocytes stimulated with SSc-EVs alone and together with the monoclonal AT1R ab was induced.ConclusionThe secretion of pro-fibrotic CCL18 by human monocytes in response to a monoclonal AT1R antibody as well as to SSc IgG indicates that anti-AT1R abs are involved in the SSc pathogenesis. Further, this effect could also be due to SSc-EVs potentially presenting anti-GPCR abs to their receptors on immune cells.References[1]Cabral-Marques O, et al.

Abstract
BackgroundAnti-neutrophil cytoplasmic autoantibodies specific for myeloperoxidase (MPO-ANCA) are found in 10-70% of the patients with eosinophilic granulomatosis with polyangiitis (EGPA) depending on disease activity, methodological aspects and cohort examined [1-3]. Recently, a higher prevalence of anti-pentraxin 3 (PTX3)-ANCA has been reported in EGPA compared to granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) [4].ObjectivesTo investigate the spectrum of ANCA specificities in a multicenter cohort of patients with EGPA and identify novel ANCA antigens.MethodsWe conducted a retrospective analysis of 73 patients with EGPA treated between 2015 and 2020 in 3 tertiary referral centers. In addition to in-house ANCA testing with indirect immunofluorescence (IFT) on fixed human granulocytes and antigen-specific enzyme-linked immunosorbent assays (ELISA), ANCA specificities were determined using a cell-based assay (CBA; Euroimmun, Lübeck, Germany). Diagnosis was based on Chapel Hill consensus conference definitions, ACR- and MIRRA-criteria for EGPA. Patient characteristics and clinical manifestations were evaluated and compared based on ANCA status. Fisher`s exact test was employed for comparison of patient groups.ResultsANCA findings are summarized in Table 1. MPO- and proteinase 3 (PR3)-ANCA positive patients (13.7%) had a higher prevalence of peripheral neuropathy (70% vs. 44.4%, p = 0.0003) and glomerulonephritis (20% vs. 14.3%, not significant). MPO- and PR3-ANCA-negative patients (86.3%) had a higher prevalence of heart (10% vs. 46%, p <0.0001), central nervous system (CNS) (0% vs. 14.3%, p <0.0001) and gastrointestinal (10% vs. 22.2%, p = 0.0327) involvement. PTX3-ANCA were associated with a higher prevalence of ear-nose-throat (ENT) (100% vs. 85.3%, p <0.0001), lung (100% vs. 89.7%, p = 0.0015), gastrointestinal involvement (60% vs. 17.6%, p <0.0001) and peripheral neuropathy (100% vs. 48.5%, p <0.0001). Kidney (0% vs. 16.2%, p <0.0001) and CNS involvement (0% vs. 13.2%, p = 0.0002) occurred less frequently in PTX3-ANCA positive patients. The 2 olfactomedin 4 (OLM4)-ANCA positive patients presented with ENT, lung and kidney involvement, and polyneuropathy, respectively.Table 1.ANCA in EGPA cohort (n = 73). BPI = bactericidal permeability-increasing protein.IFT / ELISANo. of patients (%)P-ANCA11 (15.1)C-ANCA5 (6.8)MPO-ANCA8 (10.9)PR3-ANCA2 (2.7)BPI-ANCA1 (1.4)PTX3-ANCA5 (6.8)OLM4-ANCA2 (2.7)ConclusionWe report on the detection of PTX3-, BPI- and OLM4-ANCA in addition to MPO- and PR3-ANCA in EGPA. OLM4-ANCA has been reported in 2 patients with non-vasculitic inflammatory symptoms previously [5]. Herein, detection of OLM4-ANCA in EGPA is reported for the first time. Our study shows that the presence of ANCA with various specificities other than MPO and PR3 contribute to a higher prevalence of ANCA in EGPA. Moreover, clinical manifestations differ between ANCA-negative EGPA and ANCA-positive EGPA, and between patients with different ANCA-specificities.References[1]Schönermarck U, et al.

Abstract
BackgroundCardiac manifestations in systemic sclerosis (SSc) can be either due to the fibrotic and vascular process or secondary to pulmonary arterial hypertension (PAH), cardiac inflammation, or renal crisis. Despite being one of the leading causes of death in SSc, cardiac involvement and its therapeutic options have been poorly studied. According to the ACR/EULAR recommendations, therapy with cyclophosphamide (CP) is applied to patients with cardiac manifestations. However, in case of inadequate response to CP, there are no other therapeutics evaluated.ObjectivesThe aim of this retrospective analysis was to explore the efficacy of a therapy with rituximab and mycophenolic acid (MPA), especially in cases of CP failure or therapy induced cardiac toxicityMethods14 Patients with SSc and cardiac involvement (defined as troponin T elevation plus right- or left ventricular systolic or diastolic dysfunction, myocarditis, pericarditis, right heart failure secondary to PAH, or arrhythmias) were analysed. Two patients each showed concomitant myositis and rheumatoid arthritis, respectively. Twelve patients were initially treated with CP and two patients with methotrexate (MTX). Due to a disease progress (either cardiac involvement, skin fibrosis or lung function) a therapy with rituximab and MPA was initiated [1] These patients were followed for up to five years.ResultsBefore initiation of CP or MTX electrocardiogram showed arrhythmias (atrial fibrillation, conduction blocks, multifocal ventricular extrasystoles (VES)) in 9 patients. Echocardiography revealed abnormalities in 10 patients including reduced left-ventricular ejection fraction (LV-EF), diastolic dysfunction, mitral regurgitation, or aortic aneurysm. 3 patients had PAH, 2 patients were diagnosed with post capillary pulmonary hypertension. Cardiac MRI revealed signs of myocarditis in 4 patients. 4 patients required cardiac resynchronization therapy or pacemaker implantation. Moreover, body plethysmography showed a reduction in forced vital capacity (FVC) in 12 patients, suggestive of restrictive lung disease. Under therapy with CP 11 patients had suffered from disease progress, 1 patient developed relapsing pneumonias and the 2 patients with overlap rheumatoid arthritis developed cardiac disease manifestations on MTX monotherapy. Consequently, rituximab 1000 mg q12weeks and MPA 1000 mg bid were initiated. Under this combination troponin T decreased in all patients (p=0.0002), LV-EF improved in 5, remained normal in 7 and deteriorated in 2 patients. The rate of VES improved in 8 patients. In one patient, myocarditis resolved completely (MRI). Moreover, pulmonary artery systolic pressure, measured by echocardiography, improved in all patients diagnosed with PAH under stable therapy. The modified Rodnan skin score improved in all patients, FVC improved in 7 patients, remained stable in 6 and decreased in the patient with overlap myositis. Rituximab infusions could be extended (1000 mg q24weeks) after 24-36 months of treatment in 11 patients. All patients showed peripheral blood depletion of B cells without noticed severe IgG deficiency. While 11 patients did not develop severe complications 2 patients died during follow-up of pneumonia and cardiogenic shock (overlap myositis), respectively and one patient developed a relapse of lung cancer with cerebral metastasis.ConclusionTherapy with rituximab and MPA is a promising alternative. However, its use requires risk stratification of patients with respect to adverse side effects which needs to be explored in future studies.References[1]Rimar D, Rosner I, Slobodin G.

Abstract
BackgroundScleroderma renal crisis (SRC) is a vascular complication of systemic sclerosis (SSc) with substantial risks for end-stage renal disease and death. Activating autoantibodies (Abs) targeting the angiotensin II type 1 (AT1R) and the endothelin-1 type A receptor (ETAR) are suggested to contribute to the vasculopathy in SSc (1, 2).ObjectivesHere, we sought to determine their pathogenic significance for acute renal vascular injury.MethodsIgG from patients with SRC was studied for AT1R and ETAR dependent biologic effects on isolated rat renal interlobar arteries and vascular cells including contraction, signaling, and mechanisms of receptor activation. A cohort of ten patients with refractory SRC received multimodal treatment including AT1R and ETAR inhibition and plasma exchange and was followed for improvement of kidney function.ResultsIn myography experiments, patient IgG exerted vasoconstriction (mean 6.5% of KCl induced contraction [95% confidence interval (95 CI) 5.0-8.1]) whereas control IgG did not (0.6% [95 CI 0.3-1.0]). The response was sensitive to inhibition of AT1R (3.0% [95% CI 1.4-4.7]) and ETAR (1.0% [95 CI 0.6-1.3]) and relied on MEK-ERK signaling. Contraction induced by angiotensin II and endothelin-1 was amplified by anti-AT1R and anti-ETAR Abs with substantial crosstalk between both receptors implicating autoimmune receptor hypersensitization. Co-immunoprecipitation experiments indicated heterodimerization between both receptor types enabling functional interrelation by structural interactions. 30% of patients with refractory SRC had improved kidney function after multimodal therapy.ConclusionWe provide experimental and clinical evidence that agonistic Abs may contribute to SRC. Novel therapies targeted at autoimmune hyperactivation of AT1R and ETAR might improve outcomes in severe cases of SRC.References[1]Riemekasten, G. et al.

Abstract
BackgroundFibromyalgia syndrome (FMS) is often present in autoimmune diseases but can also occur in its primary form. Biomarkers for FMS are currently missing. Systemic chronic inflammation, dysautonomia and metabolic dysfunction have been suggested to contribute to the disease. Recent studies indicate that FMS involves autoantibodies (abs), which bind to neurons, macrophages and endothelial cells.ObjectivesIn the present study, we aimed to delineate changes in natural abs directed to neuro- and vasoregulatory molecules and potentially confounding factors, which could influence these abs and disease state.MethodsSera from 91 patients with primary FMS (pFMS), 24 patients with secondary FMS (sFMS) and 31 healthy controls (HC) were analysed for the presence of 27 different natural abs directed to e.g., cholinergic, opioid, cannabinoid, endothelin or complement receptors or angiotensin system molecules by individual ELISAs (CellTrend GmbH, Luckenwalde, Germany). All participants were characterized by several questionnaires to obtain demographic data and measures of disease state (using the Widespread Pain Index (WPI) and Symptom Severity Score (SSS)). Linear regression on log-transformed ab levels adjusted for potential confounders was used to compare ab levels between groups. Random forest analysis was applied to differentiate between pFMS and HC by measuring the Area Under the Curve Receiver operating characteristics (AUC-ROC).ResultsCompared to HC, patients with pFMS showed increased levels of abs directed to ACE II, the angiotensin receptor type-2 (AT2R), the cannabinoid receptor type 1 and 2 (Can1-R, Can2-R), the endothelin receptor type-B (ETBR), the opioid receptor κ (Op-k-R) and lower levels against the complement receptor 5a (C5a-R) and the muscarinergic acetylcholine receptor type 3 (M3)(Figure 1). After adjustment for age (linear and squared) and sex, differences in the ab levels remain significant for abs against ACE II, AT2R, ETBR and the Op-k-R. However, none of which remained significant after further adjustment for Body Mass Index (BMI). Random forest analysis of unadjusted ab levels revealed an AUC-ROC of 0.94 for pFMS compared to HC with an average accuracy of 0.85 and a kappa of 0.55. Again, after adjusting the ab levels for age, sex and the BMI, AUC-ROC to discriminate HC from pFMS patients decreased to 0.73 (accuracy = 0.79, kappa = 0.33).Figure 1.Boxplots of logarithmized abs levels between groups. *: p < .05 in unadjusted analysis and after adjusting for age and sex, ~: p < .05 only significant after adjusting for age and sex, +: p < .05 only in unadjusted analysis (all FDR-corrected within group comparisons across abs). Unadjusted Adjusted for age, sex and BMIConclusionAbs might be potential biomarkers for pFMS. However, these results highlight the important role of correct covariate adjustment for research on biomarkers supposed to classify FMS or other diseases. In FMS, increase in BMI might be a cause or a consequence of FMS and it is also unknown how BMI and abs influence each other. Thus, BMI might or might not be a confounder so that adjusting for BMI might be correct or incorrect. However, these abs could provide a link to understand how acquired conditions interact with the immune system.References[1]Goebel A et al.

Abstract
BackgroundA defect in regulatory T cell (Treg) homeostasis due to an acquired deficiency of interleukin-2 (IL-2) plays an important role in the pathogenesis of systemic lupus erythematosus (SLE).1,2 However, it is still unclear whether a defect in the Treg-IL-2 axis is also involved in other connective tissue disease such as inflammatory myopathies or primary Sjogren´s syndrome (pSS).ObjectivesThe aim of our study was to investigate whether Treg from patients with poly- and dermatomyositis (PM/DM) and pSS display typical features of IL-2 deficiency in parallel to phenotypic alterations of conventional CD4+ T cell (Tcon) subsets compared to healthy controls (HC).MethodsPBMC were isolated from patients with PM/DM (n=22) and pSS (n=17) and from age- and sex-matched HC (n=19) using gradient density centrifugation. Treg and Tcon subsets were analyzed by using multicolor flow cytometry. Mann-Whitney test was used for statistical analyses.ResultsFrequencies of FoxP3+CD127lo Treg among CD3+CD4+T cells were higher in pSS compared to PM/DM patients (p<0.001) and to HC (p<0.05). However, in both, PM/DM and pSS patients, frequencies of CD25+ cells among FoxP3+CD127lo Treg were significantly lower compared to HC (PM/DM: p<0.05, pSS: p<0.0001), while the frequencies of Helios+ cells among the CD25- Treg subset were substantially higher in pSS patients compared to DM/PM and HC (both p<0.001). Conversely, we found lower frequencies of CXCR5+ follicular Treg only in PM/DM patients (p<0.05). In parallel, there were higher frequencies of CD45RO+CCR7- effector/memory cells (p<0.01) and of Ki67+ proliferating cells (p<0.05) among CD3+CD4+FoxP3- Tcon in pSS patients compared to HC, which was not observed in PM/DM patients.ConclusionThe loss of the CD25+ Treg subset in PM/DM and pSS patients is similar to previous findings in SLE patients1 and represents a hallmark of IL-2 deficiency. This suggests that shortage of IL-2 is pathophysiologically relevant also in PM/DM and pSS providing a rationale for low-dose IL-2 therapy in these diseases. In addition, activation and expansion of effector/memory Tcon appears to be more pronounced in pSS compared to PM/DM. The different distribution of Treg and of Tcon subsets between pSS and PM/DM patients might reflect differences in the availability of IL-2 and in the regulation of Tcon responses in these diseases.References[1]von Spee-Mayer C, Siegert E, Abdirama D, et al.

Abstract
BackgroundSkin fibrosis is a cardinal feature of systemic sclerosis (SSc) and associated with significant disability. The early trajectory of skin fibrosis provides insights into the course of the disease including mortality; however, little is known about late skin fibrosis in SSc.ObjectivesThe aims of our study were to ascertain the prevalence and characteristics of late skin fibrosis in SSc.MethodsWe developed and tested three conceptual scenarios of late (>5 years after 1st non-RP sign or symptom) skin fibrosis (Figure 1):Figure 1.Conceptual models/scenarios of late skin fibrosis in SSc. A: worsening and then improvement (>3 mRSS) during the first 5 years, and then worsened again after 5 years. B: worsening for the first time after 5 years. C: worsening in the first 5 years and stayed high after 5 years (i.e., failure to improve).A. Worsening and then improvement (>3 mRSS) during the first 5 years, and then worsened again after 5 years.B. Worsening for the first time after 5 years.C. Worsening in the first 5 years and stayed high after 5 years (i.e., failure to improve).We defined skin worsening as modified Rodnan skin score (mRSS) ≥ 5 units or ≥ 25%. Using strict inclusion criteria including complete mRSS, we identified 1,043 (out of 19,115) patients within the EUSTAR database for our analysis. We further restricted analysis within 887 (out of 1,043) patients who had limited (lcSSc) or diffuse cutaneous SSc (dcSSc) at baseline.ResultsOne-fifth of patients among the whole cohort (n=208/1043, 19.9%) including in patients with lcSSc or dcSSc at baseline (n=193/887, 21.8%) developed late skin fibrosis. This was largely due to new skin worsening or failure to improve. Patients with lower baseline mRSS and lcSSc were more likely to develop late skin fibrosis. Anti-Scl-70 antibodies (Table 1) were associated with progression from baseline lcSSc to dcSSc, and anticentromere antibodies were protective.Table 1.Impact of autoantibody status on progression from baseline limited to diffuse cutaneous SSc (dcSSc).Skin worsening after 5 years (Scenario B) (n=70)Skin worsening within 5 years and failed to improve after 5-year window (Scenario C) (n=61)Progressed to dcSSc (n=23)Not progressed to dcSSc(n=47)P-valueProgressed to dcSSc (n=37)Not progressed to dcSSc(n=24)P-valueAnticentromere+ve2/22 (9.1%)19/42 (45.2%)0.00346/34 (17.6%)14/21 (66.7%)0.0002-ve20/22 (90.9%)23/42 (54.8%)28/34 (82.4%)7/21 (33.3%)Anti-Scl-70+ve15/23 (65.2%)14/44 (31.8%)0.008822/36 (61.1%)8/23 (34.8%)0.0485-ve8/23 (34.8%)30/44 (68.2%)14/36 (38.9%)15/23 (65.2%)Anti-RNA-Polymerase-III+ve0/12 (0.0%)1/22 (4.5%)1.00000/6 (0.0%)0/14 (0.0%)---ve12/12 (100%)21/22 (95.5%)6/6 (100%)14/14 (100%)ConclusionLate skin fibrosis affects approximately 20% of SSc patients >5 years after onset of disease. We have identified different patterns relevant to clinical practice and trial design. Late skin fibrosis is usually due to new worsening or failure of skin to improve. Progression from baseline limited to diffuse cutaneous SSc was associated with anti-Scl-70 antibodies, and anticentromere antibodies were protective. Late skin fibrosis is a neglected manifestation of SSc and warrants further investigation including to determine clinical outcomes and optimal therapeutic strategy.AcknowledgementsOn behalf of EUSTAR collaborators.Disclosure of InterestsMichael Hughes Speakers bureau: Speaking fees from Actelion pharmaceuticals, Eli Lilly, and Pfizer, outside of the submitted work, Suiyuan Huang: None declared, Juan Jose Alegre Sancho Speakers bureau: Speaking and/or investigational fees from Actelion pharmaceuticals, Eli Lilly, Pfizer, Boehringer Ingelheim, Roche, and GSK, outside of the submitted work, Grant/research support from: Speaking and/or investigational fees from Actelion pharmaceuticals, Eli Lilly, Pfizer, Boehringer Ingelheim, Roche, and GSK, outside of the submitted work, Patricia Carreira: None declared, Merete Engelhart: None declared, Eric Hachulla Speakers bureau: Received consulting fees/meeting fees from Johnson & Johnson, Boehringer Ingelheim, Bayer, GSK, Roche-Chugai, Sanofi-Genzyme; speaking fees from Johnson & Johnson, GSK, Roche-Chugai; and research funding from CSL Behring, GSK, Roche-Chugai and Johnson & Johnson., Consultant of: Received consulting fees/meeting fees from Johnson & Johnson, Boehringer Ingelheim, Bayer, GSK, Roche-Chugai, Sanofi-Genzyme; speaking fees from Johnson & Johnson, GSK, Roche-Chugai; and research funding from CSL Behring, GSK, Roche-Chugai and Johnson & Johnson., Jörg Henes Speakers bureau: Lectures for CHUGAI, Boehringer-Ingelheim, Eduardo Kerzberg: None declared, Maria Rosa Pozzi: None declared, Gabriela Riemekasten: None declared, Vanessa Smith: None declared, Gabriella Szucs: None declared, Marie Vanthuyne: None declared, Elisabetta Zanatta: None declared, Oliver Distler: None declared, Armando Gabrielli: None declared, Anna-Maria Hoffmann-Vold: None declared, Viginia Steen: None declared, Dinesh Khanna Shareholder of: DK has stock options in Eicos Sciences, Inc., Consultant of: Consultant for Acceleron, Amgen, Boehringer Ingelheim, CSL Behring, Chemomab, Genentech/Roche, Horizon, Mitsubishi Tanabe Pharma, Prometheus, Talaris., Grant/research support from: Has received grants from Bayer, BMS, Horizon and Pfizer (to University of Michigan).

Abstract
BackgroundPulmonary arterial hypertension (PAH) is a major clinical challenge in systemic sclerosis (SSc), and is associated with high mortality. Risk stratification provides an estimate for individual patient risk of 1-year mortality. The aim is to detect patients with the worst prognosis to optimize management strategies. Nine risk stratification approaches have been proposed in PAH, but have not been validated in SSc-PAH.ObjectivesTo assess four risk stratification models and their performance to predict 1- and 3- year mortality and to identify the best risk assessment approach for SSc-PAH.MethodsWe included all patients with SSc diagnosed with PAH by right heart catheterization (RHC) from the European scleroderma trial and research (EUSTAR) database from 2001 to February 2021. PAH was defined as mean pulmonary arterial pressure (mPAP) ≥25 mmHg, pulmonary artery wedge pressure (PAWP) ≤15mmHg, and pulmonary vascular resistance (PVR) >3 Wood units (WU) in the absence of significant interstitial lung disease. We applied four different approaches for risk stratification at time of PAH diagnosis. Risk parameters included New York Heart Association (NYHA) class, 6-minute walk distance (6MWD), NT-proBNP or BNP, and echocardiographic and hemodynamic parameters with cut-off values based on the 2015 ESC/ERS Guidelines. Model 1 and 2 stratified patients into low, intermediate and high-risk categories; while Model 3 and 4 stratified the patients into four categories (low, intermediate-low, intermediate-high and high).Model 1: Patients with ≥ 1 high-risk parameter were considered at high risk; with ≥ 1 intermediate-risk parameter at intermediate risk, otherwise at low risk1Model 2: Each variable was graded from 1 to 3 representing low to high risk. The mean of available risk parameters was rounded to the nearest integer to define the risk category2Model 3: Equals Model 2, but the intermediate risk group was divided into intermediate-low and intermediate-high based on the mean score3Model 4: Stratifies patients into four risk categories based on the proportion of low-risk parameters3We performed analysis of 1- and 3- year mortality in patients with a minimum follow-up of 1 and 3 years, respectively.ResultsOf 911 patients who conducted RHC, 273 (30%) were diagnosed with SSc-PAH according to the inclusion criteria (Table 1). Median follow-up time was 2.8 years (IQR 1.3-5.3). The models varied in their ability to predict mortality (Figure 1). Model 1 and 4 either over- or underestimated mortality. Model 2 stratified patients according to the expected 1-year mortality of <5%, 5-10% and >10% suggested by the ESC/ERS Guidelines. Model 3, which divided the intermediate risk group in two different risk groups, segregated the risk of mortality further within this group.Table 1.Demographic and clinical characteristics of patients segregated by risk stratification (Model 3)NAll patients (n=273)Low-risk (n=78)Intermediate-low (n=118)Intermediate-high (n=56)High-risk (n=21)Age, years (SD)27365 (10.7)65 (10.3)65 (10.7)65 (10.8)67 (12.8)Female sex, n (%)273230 (84)64 (82)98 (83)48 (86)20 (95)lcSSc, n (%)263221 (84)60 (80)99 (86)47 (90)15 (71)NYHA 3 or 4, n (%)261155 (59)12 (16)75 (68)49 (89)19 (95)NT-proBNP, pg/ml (IQR)1111941 (230-1485)215 (103-377)763 (325-1418)1926 (1051-5681)3314 (1129-6553)6MWD, m (SD)196321 (124.1)404 (119.7)314 (99.9)262 (128.6)215 (96.0)RHC:- mPAP, mmHg (SD)27340 (11.0)35 (8.8)41 (11.5)41 (10.8)45 (11.6)- PAWP, mmHg (SD)2739 (3.2)9 (3.0)9 (3.4)9 (3.2)8 (3.1)- Cardiac index, l/min/m2(SD)2602.8 (0.8)3.2 (0.7)2.7 (0.8)2.6 (1.0)2.0 (0.5)- PVR, WU (SD)2737.4 (4.1)5.3 (2.8)7.9 (4.0)7.9 (4.2)11.3 (4.7)Figure 1.1- and 3-year mortality according to risk category in the four different modelsConclusionModel 3 provides signals for a better risk stratification of patients with newly diagnosed SSc-PAH, with progressively increasing mortality across the categories.

Abstract
BackgroundThe course of SSc-ILD is variable, and may include periods of stability or even improvement in forced vital capacity (FVC) as well as periods of decline.ObjectivesTo investigate the baseline characteristics of patients with SSc-ILD in the placebo group of the SENSCIS trial whose ILD improved or progressed over 52 weeks.MethodsThe SENSCIS trial enrolled patients with SSc with first non-Raynaud symptom in the prior ≤7 years, extent of fibrotic ILD on high-resolution computed tomography (HRCT) ≥10% and FVC ≥40% predicted. Patients who had been taking a stable dose of mycophenolate for ≥6 months were allowed to participate. We investigated the baseline characteristics of patients in the placebo group whose ILD showed improvement (absolute increase in FVC ≥5% predicted), stability (absolute decline or increase in FVC <5% predicted), progression (absolute decline in FVC ≥5% predicted), or significant progression (absolute decline in FVC ≥10% predicted) over 52 weeks. P-values based on ANOVA or Chi-squared tests were used to compare the baseline characteristics of the patients who showed improvement, stability and progression.ResultsOf 288 patients, 21 (7.3%) showed improvement, 166 (57.6%) stability, and 101 (35.1%) ILD progression, of whom 37 (12.8% of all patients) had significant ILD progression over 52 weeks. Most baseline characteristics were similar across the groups based on progression, but there were differences in DLCO % predicted (p=0.02) and in the proportion of patients taking mycophenolate (p=0.09) among patients who showed improvement, stability and progression (Table 1).Table 1.Baseline characteristics of patients in the placebo group of the SENSCIS trial in subgroups based on course of SSc-ILD over 52 weeks.Improvement (n=21)Stability (n=166)Progression (n=101)Significant progression (n=37) (subset of Progression)P-value for comparison of Improvement, Stability, ProgressionAge, years55.9 ± 12.053.2 ± 12.653.1 ± 12.855.3 ± 11.80.64Female71.475.970.373.00.59Years since first non-Raynaud symptom3.7 ± 1.73.5 ± 1.73.5 ± 1.93.6 ± 1.90.81Diffuse cutaneous SSc47.649.453.556.80.78Anti-topoisomerase I antibody positive61.958.466.356.80.44High sensitivity C-reactive protein, mg/L5.1 ± 8.97.8 ± 23.05.6 ± 9.94.2 ± 4.40.62Modified Rodnan skin score9.3 ± 7.310.5 ± 8.411.9 ± 9.712.7 ± 11.30.29History of gastroesophageal reflux disease (GERD)76.272.978.278.40.62Extent (%) of fibrotic ILD on HRCT*26.4 ± 16.235.5 ± 20.436.6 ± 21.840.8 ± 23.50.12Presence of honeycombing on HRCT14.316.815.526.50.94Presence of ground glass opacities on HRCT81.086.689.784.80.51FVC % predicted77.1 ± 18.071.7 ± 17.273.3 ± 15.274.2 ± 14.80.33DLco % predicted61.5 ± 14.953.4 ± 14.851.1 ± 15.147.3 ± 14.50.02Taking mycophenolate71.448.245.535.10.09Data are mean ± SD or % at baseline.

Abstract
BackgroundAntibodies directed to the angiotensin receptor type 1 (AT1R) were found to be increased in patients with SSc ad they predict mortality and SSc complications (1, 2). In vitro studies suggested an involvement in the pathogenesis of systemic sclerosis (SSc).ObjectivesHere, we aim to determine the contribution and functions of AT1R autoantibodies (Abs) in vivo and in vitro as well as their capacity to recognize AT1R from different species.MethodsC57BL/6J mice were immunized with membrane-embedded human AT1R or empty membrane as control. Phenotypic properties of various organs were examined by immunohistochemistry, immunofluorescence, and TUNEL apoptosis assay. A monoclonal (m)AT1R Ab was generated based upon this mouse model by hybridoma technology and transferred into C57BL/6J mice. Mice deficient for CD4+ and CD8+ T cells, B cells and AT1Ra/b served as controls. In vitro, Abs responses towards AT1R were measured using rat cardiomyocytes, human epithelial cells, AT1R-transfected HEK293 cells and primary human monocytes.ResultsAT1R-immunized mice developed perivascular skin and lung inflammation, lymphocytic alveolitis, weak endothelial apoptosis and skin fibrosis, not present in controls or mice deficient for CD4+ T and B cells. The contribution of AT1R Abs to skin manifestations and interstitial lung disease was demonstrated by application of a mAT1R Ab, which induced skin and lung inflammation, not observed in the AT1Ra/b knockout mice. IgG from immunized mice containing AT1R Abs and/or the mAT1R Ab activated rat cardiomyocytes and human monocytes. Treatment of AT1R-transfected HEK293 cells with the mAT1R Ab enhanced AT1R signaling in the presence of the endogenous agonist Angiotensin II.ConclusionOur immunization strategy successfully induced AT1R Abs, contributing to inflammation and most likely to fibrosis via activation of AT1R. Therefore, AT1R Abs are valuable targets for future therapies in SSc and possibly other AT1R Ab-related diseases.References[1]Riemekasten, G. et al.

Abstract
BackgroundRisk-stratification is key in a heterogeneous disease like systemic sclerosis (SSc). Until now, SSc patients are stratified according to the extent of skin involvement into limited cutaneous, diffuse cutaneous and sine scleroderma subtypes. However, this classification remains inaccurate to capture disease heterogeneity. Autoantibodies are found in more than 90% of the patients and can be detected before onset of the disease. Among them, three predominant and specific antibodies are used: anti-centromere, anti-Scl70 and RNA polymerase III antibodies.ObjectivesTo compare the performances of stratification into LeRoy’s cutaneous subtypes versus autoantibody status in SSc versus combination of cutaneous subtypes and autoantibodies status.MethodsPatients from the EUSTAR database were classified either as (i) limited cutaneous, diffuse cutaneous or sine scleroderma (based on the recording made by the treating physician) or (ii) according to autoantibodies with the following subclassifications: (1) no specific autoantibodies, (2) isolated ANA, (3) anti-centromere antibodies, (4) anti-Scl70 antibodies and (5) anti-RNA polymerase III antibodies or (iii) according to combination of cutaneous subset and auto-antibodies. The respective performance of each model to predict overall survival (OS), progression-free survival (PFS), disease progression and different organ involvements was assessed and the three models were compared by the area under the receiver operating characteristic curve (AUC 95%CI) and the net reclassification improvement (NRI). Missing data were imputed through multiple imputation using chain equations.ResultsIn all, 10’711 patients were included: 84.6% females, mean age: 54.4±13.8 years, mean disease duration: 7.9±8.2 years. In the prospective analysis (n= 6’467 to 7’829 according to the outcome), after a mean follow-up of 56 months and a mean of three visits per patient, we did not identify any difference in AUC between the cutaneous-based model and the antibody-based model for prediction of OS and disease progression. However, the NRI showed a significant improvement in prediction of OS (0.57 [0.46-0.71] vs. 0.29 [0.19-0.39]) and disease progression (0.36 [0.29-0.46] vs. 0.21 [0.14-0.28]) at 4 years using the antibody-based model. Regarding prediction of each organ involvement in longitudinal analyses, the antibody-based model showed better performance than the cutaneous-one for renal crisis (AUC: 0.719 [0.696-0.742] vs. 0.664 [0.643-0.685]), with the highest association observed with anti-RNA polymerase III (OR: 7.47 [1.63-34.24], p= 0.010). Similarly, the antibody-based model was better than the cutaneous model in predicting lung fibrosis (AUC 0.719 [0.715-724] vs. 0.653 [0.647-0.659]) and restrictive lung fibrosis (AUC 0.759 [0.749-0.766] vs. 0.711 [0.701-0.721]) which were both associated with anti-Scl70 antibodies (OR: 9.29 [8.17-10.55] and 7.92 [5.37-11.69], respectively, p<0.0001 for both). Although there was no difference in the AUC to predict digital ulcers, NRI showed an improvement using the antibody-based model (0.31 [0.29-0.33] vs. 0.24 [0.22-0.26]) with the highest association with anti-Scl70 antibodies (OR: 3.57 [2.68-4.75], p<0.0001). The two models had similar performances in assessing occurrence of intestinal involvement, heart dysfunction or elevated sPAP. Combining both antibody status and cutaneous subtype did not improve the performance of our models. In the exploratory analysis, there was no change using modified Rodnan skin score to define cutaneous form.ConclusionAuto-antibody status outperforms the common cutaneous subsetting to risk-stratify SSc patients in the EUSTAR cohort. This easily performed subclassification using autoantibodies specific status can be used by the clinicians to risk-stratify their patients and to adapt disease monitoring in routine practice.Disclosure of InterestsMuriel Elhai Speakers bureau: BMS outside of the submitted work, Marouane Boubaya: None declared, Nanthara Sritharan: None declared, Alexandra Balbir-Gurman: None declared, Elise Siegert: None declared, Eric Hachulla: None declared, Jeska de Vries-Bouwstra: None declared, Gabriela Riemekasten: None declared, Jörg H.W.

Abstract
BackgroundShort disease duration is a predictor for progressive systemic sclerosis-associated interstitial lung disease (SSc-ILD), but studies assessing ILD progression in later disease stages are lacking. To individually tailor management of ILD in SSc patients in clinical practice it is, however, of high importance to understand disease behaviour also in patients with late disease.ObjectivesAnalyse ILD progression in SSc-ILD patients from the EUSTAR cohort segregated by subgroups of disease duration.MethodsWe segregated SSc-ILD patients into four categories of disease duration (≤3 years, >3- ≤7 years, >7- ≤15 years and >15 years after onset of Raynaud’s phenomenon). We assessed progressive ILD, defined as forced vital capacity (FVC) decline >10% or FVC decline ≥10% and FVC decline 5–10% and diffusing capacity of the lungs for carbon monoxide (DLCO) decline ≥15% (composite decline) over the first and second 12+/-3 months period after first registration (baseline) into EUSTAR. Clinical characteristics, pulmonary involvement, treatment at first registration and ILD progression were evaluated by descriptive statistics.ResultsIn total, 2258 SSc-ILD patients were included, with 469 (20.8%) having a disease duration ≤3 years, 550 (24.4%) between >3- ≤7 years, 752 (33.3%) between >7- ≤15 years and 488 (21.6%) of >15 years (Table 1). Baseline characteristics and treatment patterns differed between the four subgroups, with more younger male patients with diffuse cutaneous SSc, anti-topoisomerase I antibody and higher Rodnan skin score having ≤3 years disease duration. Lung function with FVC and DLCO were similar between the four groups (Table 1). Notably, in the first and second 12+/-3 months periods after first registration in the EUSTAR database, there were no significant difference in FVC decline >10% or composite FVC and DLCO decline within the four subgroups. For example, patients with disease duration >7- ≤15 years and >15 years frequently showed disease progression of FVC >10%: 41/347 (11.8%) and 32/228 (14%) compared to 38/244 (15.6%) and 33/273 (15.6%) for disease duration ≤3 years and >3- ≤7 years (P=0.529), respectively (Figure 1).Table 1.Demographics and baseline clinical characteristics of EUSTAR patientsDisease duration≤ years(n=460)>3- ≤7 years(n=550)>7- ≤15 years(n=752)>15 years(n=488)p-valueAge, years (SD)55 (13.5)55 (14.1)57 (13.1)61 (11.5)<0.001Male, n (%)123 (26.2)115 (20.9)112 (14.9)38 (7.8)<0.001DcSSc, n (%)228 (56.4)262 (45.8)311 (45.4)163 (31.2)<0.001ATA, n (%)236 (53.4)293 (55.9)374 (52.8)218 (48.0)0.099mRSS, mean (SD)12.3(10.1)10.4 (8.3)9.4 (8.1)8.7 (7.7)<0.001GERD, n/N (%)273 (58.7)353 (64.4)482 (64.4)344 (71.2)0.001ESR, mean (SD)26.9(21.7)24.2 (19.5)26.2 (19.9)28.3 (21.2)0.022MMF, n/N (%)33 (16.6)43 (25.2)37 (20.4)14 (9.3)0.002MTX, n/N (%)19 (10)17 (10.1)19 (10.6)8 (5.2)0.296Any IS, n/N (%)81 (38.6)89 (47.1)82 (40.8)46 (28.7)0.006FVC % pred, mean (SD)86 (20.9)87 (21.6)86 (21.4)87 (22.8)0.770DLCO % pred, mean (SD)58 (19.3)59 (19.3)59 (19.9)58 (19.7)0.405NYHA class 3&4, n (%)84 (18.6)78 (14.6)125 (17.5)22.6 (7.0)0.090Figure 1.FVC decline >10% and composite FVC and DLCO decline in the first and second 12+/-3 months within the four subgroups segregated by disease durationConclusionIt was long believed that ILD burned out in late disease stages. In our analysis of ILD progression by four disease duration categories, we showed that ILD frequently progressed also in late disease stages. This has important implications for clinical practise, as SSc patients need to be regularly monitored for ILD progression independent of disease duration.Disclosure of InterestsAnna-Maria Hoffmann-Vold Speakers bureau: Actelion, Boehringer Ingelheim, Jansen, Lilly, Medscape, Merck Sharp & Dohme, Roche, Consultant of: Actelion, ARXX, Bayer, Boehringer Ingelheim, Jansen, Lilly, Medscape, Merck Sharp & Dohme, Roche, Grant/research support from: Boehringer Ingelheim, Cathrine Brunborg: None declared, Paolo Airò Speakers bureau: Bristol-Myers-Squibb, Boehringer Ingelheim, Consultant of: Bristol-Myers-Squibb, Grant/research support from: Bristol-Myers-Squibb, Roche, Jannsen, CSL Behring, Lidia P.

Abstract
BackgroundSystemic sclerosis (SSc) is characterized by chronic inflammation that leads to damage of the vascular endothelium and excessive collagen deposition in several target organs (1). The interaction of interleukin 2 (IL-2) with the corresponding receptor (IL-2R) is involved in the regulation of autoimmune processes (2). The shedding product of the IL-2R alpha chain, soluble IL-2 receptor (sIL-2R, CD25), is able to either reduce or enhance immune responses (2). Previously, elevated serum levels of sIL-2R were found in the bronchoalveolar lavage of SSc patients with interstitial lung disease (SSc-ILD) as well as serologically in patients with early SSc, and thus suggested to be a biomarker for clinical development of SSc (3,4).ObjectivesTo examine concentrations of sIL-2 in patients with SSc and analyse their association with clinical and serological parameters.MethodsTo determine if serological levels of sIL-2R serve as predictor of clinical complications in SSc, sera were analysed [limited cutaneous SSc (lcSSc) n=160; diffuse cutaneous SSc (dSSc), n=137] using a sandwich ELISA. Clinical data (pulmonary fibrosis, PAH, mRSS, therapy) and serological markers (hs-CRP, NT-pro BNP, neutrophil counts, creatinine, hs-troponin T, creatinine kinase, beta2-microglobuline) were assessed at the time of serum sampling and up to 48 months after baseline. Clinical progress was defined by the need to change therapies.ResultsPatients with dSSc presented elevated levels of sIL-2R compared to SSc (dSSc: 673±428 U/ml vs. 646±473 U/ml, p=0.0001). In SSc general, sIL-2R levels correlated with beta2-microglobuline (r=0.6161, p<0.0001, ROC-AUC:0.8428), hs-CRP (r=0.4091, p<0.0001, ROC-AUC:0.7110), NT-proBNP (r=0.2610, p<0.0001, ROC-AUC:0.6793), neutrophil count (r=0.2749, p<0.0001) and hs-troponin T (r=0.4548, p<0.0001, ROC-AUC:0.8729). Further, sIL-2R levels discriminated normal from pathological levels of hs-troponin T (sensitivity 80.0%, specificity 80.1%). Using Log-rank test and Mantel-Cox proportional hazard models, we found that sIL-2R levels above 745.5 U/ml predicted early clinical progress in SSc (HR: 3.45, p=0.0070, Figure 1) within 12 months.Figure 1.Kaplan-Meier survival analysis for the complete group of patients with SSc. Soluble Il-2R levels above 745U/ml were associated with early progress in SSc.ConclusionIn SSc, serum levels of sIL-2R could be of diagnostic value by identifying clinical progress. Its role in pathophysiology, especially with regard to disease manifestations such as cardiac involvement needs to be investigated in more detail.References[1]Blagojevic J et al.

Abstract
BackgroundEnrichment strategies from clinical trials for progressive systemic sclerosis-associated interstitial lung disease (SSc-ILD) have been partly successful but have not been tested in a real life cohort.ObjectivesAnalyse the efficacy, representativeness and feasibility of enrichment strategies in SSc-ILD patients from the EUSTAR cohort.MethodsWe applied the inclusion criteria of major recent SSc-ILD trials (focuSSced, SLS II and SENSCIS) in SSc-ILD patients and assessed progressive ILD, defined as absolute change in forced vital capacity (FVC) and as significant progression (FVC decline >10%) over time. Data were compared to all patients and patients not fulfilling any inclusion criteria.ResultsIn total, 2258 SSc-ILD patients were included, with 31.2% meeting SENSCIS, 5.8% SLS II, 1.6% focuSSced criteria and 1529 (67.7%) not meeting any criteria (Table 1). In the first 12+/-3 months, a slow FVC% decline of –0.1% was seen in the total, unselected cohort and in patients fulfilling SENSCIS criteria. Patients fulfilling criteria from focuSSced showed a strong FVC decline of –3.7%. Notably, patients enriched for SLS II criteria showed FVC improvement of +2.3% (Figure 1). Similarly, compared to the total unselected cohort, the number of significant progressive events was numerically higher in patients fulfilling focuSSced criteria, the same for SENSCIS criteria and even slightly lower for patients fulfilling the SLS2 criteria.Table 1.Demographics and baseline clinical characteristics of EUSTAR patientsNot fulfilling any criteria (n=1529)focuSSced (n=36)SLS II (n=132)SENSCIS (n=704)Age, years (SD)58.4 (2.9)51.5 (12.2)†51.2 (12.7) †54.2 (13.8) †Male, n (%)231 (15.1)7 (19)35 (27)**156 (21)*Disease duration, months (SD)156.3 (99.4)16.1 (13.9)†40.7 (25.2) †39.4 (23.9) †DcSSc, n (%)597 (43.8)36 (100) †85 (65) †35 (52) †ATA, n (%)735 (51.1)24 (67)*85 (69) †370 (56)mRSS, mean (SD)9.5 (8.3)21 (6.5)*13 (9.6)*11 (9.2)GERD, n (%)1002 (65.9)25 (69)92 (70)430 (62)ESR, mean (SD)27 (20.5)43.1 (23) †29.6 (19.6) †24.7 (20.7)MMF, n (%)75 (16.5)0 (0) †0 (0) †52 (22) †MTX, n (%)42 (9.2)0 (0) †2 (5)20 (9)FVC % predicted, mean (SD)85.7 (22.5)88 (13.6)*66 (9.1) †88 (19.8)DLCO% predicted, mean (SD)58.9 (21.5)61 (12.7)49(14.6)†59 (14.2)NYHA class, n (%)3261 (17.8)6 (19)28 (21)72 (10)*440 (2.7)0 (0)3 (2)4 (1)**P-value: 0.001–0.05; †P<0.001, between focuSSced, SENSCIS or SLS compared with not fulfilling any study criteria.In the second 12 months period, SENSCIS enriched patients had a further absolute FVC% decline as described for the total cohort. In contrast, patients fulfilling the focuSSced and SLS II inclusion criteria showed numerical improvement of lung function in the second period (Figure 1). There were no significant associations of enrichment criteria and ILD progression in the second period.Over the mean observation period of 2.3 years, patients not fulfilling any inclusion criteria showed the same FVC decline of –0.9 (12.1) as observed for the total cohort (–0.9% (12.6)). There were numerical differences in FVC changes in the enriched patient cohorts, varying from –2.8% FVC decline in patients fulfilling the focuSSced criteria to +3.4% FVC improvement with SLS II criteria.ConclusionApplication of enrichment criteria from previous clinical trials showed enrichment for progression with variable success but led to selected patient populations reducing feasibility of recruitment. These findings are important for future clinical trial design and interpretation of the results of published trials.AcknowledgementsWe thank all EUSTAR collaborators.Disclosure of InterestsAnna-Maria Hoffmann-Vold Speakers bureau: Actelion, Boehringer Ingelheim, Jansen, Lilly, Medscape, Merck Sharp & Dohme, Roche, Consultant of: Actelion, ARXX, Bayer, Boehringer Ingelheim, Jansen, Lilly, Medscape, Merck Sharp & Dohme, Roche, Grant/research support from: Boehringer Ingelheim, Cathrine Brunborg: None declared, Paolo Airò Speakers bureau: Bristol-Myers-Squibb, Boehringer Ingelheim, Consultant of: Bristol-Myers-Squibb, Grant/research support from: Bristol-Myers-Squibb, Roche, Jannsen, CSL Behring, Lidia P.

Abstract
Background:Systemic sclerosis (SSc) is a heterogeneous disease characterized by fibrosis, vasculopathy and autoimmunity. Dysfunctions causing disease pathology are characterized by the activation and recruitment of immune cells, as well as the formation of autoantibodies and cytokines. Profibrotic cytokines, such as interleukin-(IL)13, IL4 or IL6 play a crucial role in collagen production and fibrosis development [1]. Preliminary data reveal IL13 as a main driver for obliterative vasculopathy characterized by severe Raynaud phenomenon, acral ulcers and pulmonary arterial hypertension (PAH). Particularly acral ulcerations lead to a severe impairment in functional capacity in everyday life. In addition, pulmonary arterial hypertension is one of the main causes of the high mortality rate in SSc [2].Objectives:To prove the impact of IL13 in the pathogenesis of systemic sclerosis and thus provide the rationale for the identification of a potential new therapeutic target, we investigated IL13 expression in CD4 and CD8 T cells in patients suffering from systemic sclerosis compared to healthy controls.Methods:Peripheral blood mononuclear cells (PBMC) obtained from systemic sclerosis (SSc, n=31) patients and healthy controls (HC, n=13) were cultured without or in the presence of phorbol myristate acetate and ionomycin to activate T cells for cytokine production. Brefeldin A was used as an inhibitor of cytokine secretion. The intracellular IL13 and IL4 expression of CD4 and CD8 positive T cells were measured by flow cytometry and were compared between the investigated subgroups.To identify a disease phenotype mediated by IL13, the expression levels in the SSc group were correlated to clinical, laboratory and apparative parameters assessing organ dysfunction.Results:While there were no significant differences in IL4 expression between healthy and diseased individuals, analyses of IL13 positive CD4 and CD8 T cells showed significant differences compared to HC (CD8+IL13 p=0.048; CD4+IL13 p=0.0046) revealing the functional differences though high structural homology of the two interleukins. The increased expression of IL13 in T cells from patients with systemic sclerosis further supports the assumption of an interleukin mediated pathomechanism. Considering the IL13-mediated clinical phenotype, high levels were detected in patients showing signs for vasculopathy, correlation with sPAP (CD8+IL13 p=0.0392), NTproBNP (CD4+IL13 p=0.0461), creatinine (CD4+IL13 p=0.0227), angiotensin II receptor type I and endothelin receptor type A antibodies (CD4+IL13 p=0.0105, p=0.0042) was demonstrated. In addition, patients in the fourth quartile of CD4+IL13 expression showed a higher incidence of acral ulcers and pits than patients with low interleukin levels. Moreover, this group of patients had an increased cardiovascular comorbidity including atherosclerosis, coronary heart disease and arterial hypertension.Conclusion:Increased IL13 levels could be detected in patients with SSc, especially in patients with the phenotype of an obliterative vasculopathy. This indicates preliminary evidence for the use of IL13 blockers as a new therapeutic approach in systemic sclerosis.References:[1]Furue M, Mitoma C, Mitoma H, Tsuji G, Chiba T, Nakahara T, Uchi H, Kadono T.

Abstract
Background:There is renewed interest in the role of autoantibodies to predict outcomes in systemic sclerosis (SSc). Among the newly identified subsets, patients with limited cutaneous form (lcSSc) but anti-topoisomerase I antibodies (Scl70) positivity draw particular attention, and namely, assessing the risk of developing interstitial lung disease (ILD) —the main cause of death in SSc—to improve the management of Scl70-lcSSc patients.Objectives:We aimed to characterize patients with Scl70-lcSSc in the large multicenter European Scleroderma Trial and Research (EUSTAR) cohort.Methods:The EUSTAR database was locked in July 2019. We included all patients fulfilling 1980 ACR and/or 2013 ACR/EULAR criteria for SSc, with disease duration at database entry ≤3 yrs and known and stable skin form during the first 3 yrs. Patients with lcSSc were compared: Scl70-lcSSc (target group) vs. ACA-lcSSc and ANA-lcSSc (Step 1); and Scl70-lcSSc vs. Scl70-dcSSc (Step 2). In the ANA subgroup we included ANA+ patients with negative SSc-specific antibodies (Scl70, ACA, RNA polymerase III). In each step, we performed 5 generalized mixed models (GMM) for the risk of the new onset of ILD (defined by imaging), primary myocardial involvement (PMI), pulmonary hypertension (PH), “any severe” (ILD+PMI+PH+scleroderma renal crisis) and all-cause-mortality. An additional GMM assessed the risk of forced vital capacity (FVC) decline ≥10% vs. FVC value at ILD onset. Each GMM was adjusted for age, sex and confounders.Results:Overall, 1285 SSc patients were included: 1068 (83%) females, 860 (67%) lcSSc and 425 (33%) dcSSc. Among patients with lcSSc, 537 (62%) had ACA+, 194 (23%) Scl70+ and 129 (15%) ANA+; 425 patients had dcSSc and Scl70+. Median follow-up was similar in all 4 groups: 7.2 to 8.1 yrs.Step 1: At baseline, Scl70-lcSSc patients had significantly shorter time from Raynaud’s phenomenon (RP) to SSc onset, higher mRSS (5.8±4.8 vs. 4.3±4, p=0.001), and higher rate of articular and muscular involvement vs. ACA-lcSSc patients (Figure 1). No differences were found between Scl70-lcSSc and ANA-lcSSc comparing the aforementioned variables. ILD was more frequent in Scl70-lcSSc (46%) than in ACA-lcSSc (10%) and ANA-lcSSc (25%), as well as restrictive lung disease. GMM showed that Scl70-lcSSc carries a higher risk of ILD than both ACA-lcSSc (HR 4.55, 95%CI 3.23-6.67) and ANA-lcSSc (HR 2.17, 95%CI 1.39-3.45), with a rate of FVC decline ≥10% over time similar to the other limited forms. In Scl70-lcSSc patients the risk of “any severe” organ involvement was similar to ANA-lcSSc and higher than ACA-lcSSc (HR 1.89, 95%CI 1.40-2.50). In particular, Scl70-lcSSc shows a risk of PMI similar to ANA-lcSSc and lower than ACA-lcSSc; no differences regarding PH risk. The mortality risk in patients with Scl70-lcSSc was similar to the other limited forms’.Step 2: At baseline, time from RP to SSc onset was longer in patients with Scl70-lcSSc, with less frequent joint synovitis and tendon friction rubs vs. patients with Scl70-dcSSc. Conversely, the frequency of muscular, cardiac and pulmonary involvement was similar. The risk of ILD in Scl70-lcSSc patients was similar to Scl70-dcSSc, with a lower risk of FVC decline ≥10% over time. The risk of “any severe” involvement (HR 0.66, 95%CI 0.49-0.83), PMI and PH was lower and the mortality risk tended to be lower (HR 0.57, 95%CI 0.33-1.01, p=0.053) vs. Scl70-dcSSc.Conclusion:In our large multicenter EUSTAR cohort one quarter of lcSSc patients were Scl70+. We show a ranking for major organ involvement within lcSSc: Scl70 the most severe, ANA+ intermediate and ACA the milder form. Scl70-dcSSc patients present the most severe phenotype, and Scl70 positivity, more than the cutaneous subset, is strongly predictive of ILD, whereas other variables may influence progression. These results may provide new insight to improve the management of Scl70-lcSSc patients.Disclosure of Interests:Elisabetta Zanatta: None declared, Dörte Huscher: None declared, Paolo Airò: None declared, Alexandra Balbir-Gurman: None declared, Elise Siegert: None declared, Augusta Ortolan: None declared, Marco Matucci-Cerinic: None declared, Franco Cozzi: None declared, Gabriela Riemekasten: None declared, Anna-Maria Hoffmann-Vold: None declared, Oliver Distler Speakers bureau: has/had consultancy relationship and/or has received research funding in the area of potential treatments for systemic sclerosis and its complications from (last three years): Abbvie, Acceleron Pharma, Amgen, AnaMar, Arxx Therapeutics, Baecon Discovery, Blade Therapeutics, Bayer, Boehringer Ingelheim, ChemomAb, Corbus Pharmaceuticals, CSL Behring, Galapagos NV, Glenmark Pharmaceuticals, GSK, Horizon (Curzion) Pharmaceuticals, Inventiva, iQvia, Italfarmaco, iQone, Kymera Therapeutics, Lilly, Medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Novartis, Pfizer, Roche, Sanofi, Serodapharm, Topadur, Target Bioscience and UCB.

Abstract
Background:SSc is a heterogeneous autoimmune disease characterised by fibrosis of the skin and internal organs. In most patients with SSc-ILD, organs other than the lungs are also affected. In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in forced vital capacity (FVC) (mL/year) over 52 weeks by 44% versus placebo.Objectives:We investigated the extent of organ involvement related to SSc at baseline in patients in the SENSCIS trial and the effect of nintedanib versus placebo on the rate of FVC decline in subgroups by internal organ involvement.Methods:The SENSCIS trial enrolled patients with SSc-ILD with first non-Raynaud symptom ≤7 years before screening, extent of fibrotic ILD ≥10% on high-resolution computed tomography (HRCT) and FVC ≥40% predicted. Patients with clinically significant pulmonary hypertension were excluded. Patients were randomised to receive nintedanib or placebo until the last patient reached week 52 but for ≤100 weeks. In post-hoc analyses, we analysed the rate of decline in FVC (mL/year) over 52 weeks in subgroups with and without different types of SSc-related internal organ involvement (upper gastrointestinal; lower gastrointestinal; cardiovascular [CV]; peripheral vascular; muscular; joint). These subgroups were defined based on patients’ SSc-related medical history as reported in the case report form. A random slope and intercept model was used to assess the rate of decline in FVC (mL/year) and an interaction test applied to assess potential heterogeneity in the treatment effect of nintedanib between the subgroups.Results:Of 576 patients, 96.9% had peripheral vascular involvement, 75.5% had upper gastrointestinal and 39.8% lower gastrointestinal involvement, 45.7% had CV involvement, 40.6% had joint involvement, and 27.1% had muscular involvement at baseline. In the placebo group, the rate of decline in FVC (mL/year) was numerically greater in patients with than without upper gastrointestinal involvement and in patients without than with joint involvement or muscular involvement (Figure). The exploratory interaction p-values did not indicate heterogeneity in the treatment effect of nintedanib versus placebo on reducing the rate of decline in FVC (mL/year) between the subgroups based on organ involvement (p>0.05 for all treatment-by-time-by-subgroup interactions) (Figure).Conclusion:Patients in the SENSCIS trial had diverse complications related to SSc. There was no evidence of a differential treatment effect of nintedanib on reducing the rate of decline in FVC based on gastrointestinal, CV, joint, or muscular involvement at baseline.Acknowledgements:The SENSCIS trial was funded by Boehringer Ingelheim.

Abstract
Background:Identifying fibrosing interstitial lung disease (ILD) at the earliest opportunity remains one of the most urgent challenges for the effective management of this potentially rapidly progressive and burdensome condition, which is frequently associated with several connective tissue diseases (CTDs). However, knowledge on how to identify early hallmarks and predictors of fibrosing ILD, as well as knowing which steps to take next is frequently lacking in clinical practice.Objectives:This study was conducted to determine whether online independent medical education could improve rheumatologists’ and pulmonologists’ knowledge and competence in identifying and managing progressive fibrosing ILDs earlier in the disease course.Methods:Rheumatologists and pulmonologists participated in five ~10-min presentations about the early identification of fibrosing ILD in patients with or without CTDs and completed all pre- and post-questions.1 The effects of the education on knowledge and competence were assessed using a 3-question, repeated pairs, pre-assessment/post-assessment study design. For all questions combined, the chi-square test assessed differences from pre- to post-assessment. P values <.05 are statistically significant. The activity launched on October 9, 2020, and data were collected through December 18, 2020.Results:Overall significant improvements were seen after participation for both rheumatologists (average correct response rate of 28% at pre-assessment vs 74% at post-assessment; P<.001, representing a 165% relative percentage change [RPC]; N=39), and pulmonologists (average correct response rate of 39% at pre-assessment vs 67% at post-assessment; P<.001, representing a 72% RPC; N=102). Specifically, significant improvements were observed in clinicians’ knowledge of predictors of fibrosing ILD in patients with CTD, as well as competence in selecting the right HRCT parameters to assess prognosis and select a treatment approach to reduce the risk of disease progression (Figure 1).Figure 1.After participating in the activity, 59% of rheumatologists and 50% of pulmonologists had measurable improved confidence related to identifying early disease progression in patients with progressive fibrosing ILDs.Given the very low rates of correct responses at baseline regarding predictors of fibrosing ILD and assessing prognosis, it will be important to continue to reinforce these learnings in ongoing educational programs.Conclusion:This study demonstrates the success of segmented online education in improving rheumatologists’ and pulmonologists’ knowledge and competence in evaluating risk and prognosis of fibrosing ILD and managing patients with CTD-ILDs. This could lead to earlier changes in therapeutic approach for those with signs of progression and result in improved overall outcomes for these patients.References:[1]Kolb M, Maher T, Smith V, Jacob J, Rimekasten G.

Abstract
Background:The morbidity and mortality of systemic sclerosis (SSc) are largely determined by vascular and fibrotic pathologies. Levels of autoantibodies (ab) against G protein-coupled receptors (GPCR), growth factors (GF) and growth factor receptors (GFR) are altered in SSc compared to healthy controls (HC) 1. Thus, higher angiotensin II receptor type 1 - (AT1R) and endothelin receptor type A - (ETAR) ab levels are associated with severe disease and SSc-related mortality 2. CXC motiv chemokine receptor 3 - (CXCR3) and 4 - (CXCR4) ab have predictive value for deterioration of pulmonary fibrosis (PF) 3.Objectives:We used statistical methods to identify associations between disease manifestations and 28 new ab directed against GPCR, GF and GFR in SSc.Methods:Ab against the following targets were measured in sera from SSc patients (n = 177) and HC (n = 88): Adrenoceptors alpha-1 (ADRA1), alpha-2 (ADRA2), beta-1 (ADRB1), beta-2 (ADRB2); muscarinoceptors 1-5 (M1R - M5R); AT1R, ETAR, endothelin B receptor (ETBR); CXCR3, CXCR4; complement receptors 3a (C3aR) and 5a (C5aR); protease-activated receptors 1 (PAR1) and 2 (PAR2); vascular endothelial growth factor A (VEGFA) and its receptors 1 (VEGFR1) and 2 (VEGFR2), epithelial growth factor (EGF)/ - receptor (EGFR); hepatocyte growth factor (HGF)/ - receptor (HGFR), platelet-derived growth factor-AA (PDGFAA), placental growth factor (PlGF).The organ involvement (PF, cardiac involvement, PAH, gastrointestinal tract) and quantitative markers (modified Rodnan skin score, SSc activity score, pulmonary function, cardiac enzymes and echocardiography, routine laboratory, autoimmune diagnostics) as well as demographic data were recorded retrospectively at the time of sample collection. Statistical analysis was performed using the Mann-Whitney U test (MWU), Pearson correlations, ROC analysis, and age-adjusted logistic regression models.Results:In SSc 20 of 28 measured ab levels are significantly altered compared to HC. According to the Pearson correlation matrix, the ab-levels are highly correlated and build a network that differs between HC and SSc. Furthermore, altered network signatures are formed in the differentiated analysis of several disease manifestations of SSc such as SSc-subtype or PF. Based on ROC analysis, FGF-ab, ADRB1-ab and PlGF-ab are well suited to predict SSc (Figure 1).In addition, limited cutaneous SSc (lSSc) patients displayed lower levels of most ab than diffuse cutaneous SSc patients, whereas cardiac and pulmonary involvement are associated with higher ab levels. In the logistic regression lSSc is associated with lower levels of ab against M1R, M2R, C5aR, ETAR, AT1R, PAR1, EGFR. Higher levels for ab against M1R, M2R, ETBR, C5aR are associated with PF, higher levels of ab against complement receptors, adrenoreceptors and EGF with NT-proBNP elevation.Conclusion:The newly described antibodies against GPCR, GF and GFR are highly correlated. Associations with morbidity- and mortality-determining organ involvement indicate their possible functional relevance and novel pathophysiological mechanisms. As new biomarkers, some of the ab have prognostic value for SSc; for other manifestations, their value should be evaluated in further studies.References:[1]Cabral-Marques, O., Marques, A., Giil, L.M. et al.

Abstract
Background:Gastroesophageal reflux disease (GERD) occurs frequently in patients with systemic sclerosis (SSc) and SSc-associated interstitial lung disease (SSc-ILD). PPI use has to been shown to improve survival in patients with idiopathic pulmonary fibrosis, whereas to date there are no data on the use of PPI in SSc-ILD.Objectives:This study was aimed to assess whether use of PPI is associated with progression of SSc-ILD and survival.Methods:We retrospectively analysed 1931 patients with SSc and SSc-ILD from the German Network for Systemic Sclerosis (DNSS) database (2003 onwards). Kaplan–Meier analysis compared overall survival (OS) and progression-free survival (PFS) in patients with vs. without GERD (SSc and SSc-ILD), and PPI vs. no PPI use (SSc-ILD only). Progression was defined as a decrease in either % predicted forced vital capacity ≥10% or single-breath diffusing capacity for carbon monoxide ≥15%, or death.Results:GERD was not associated with decreased OS or PFS in patients with either SSc or SSc-ILD. In patients with SSc-ILD, PPI use was associated with improved OS vs. no PPI use after 1 year (98.4% [95% confidence interval: 97.6–99.3]; n=760 vs. 90.8% [87.9–93.8]; n=290) and after 5 years (91.4% [89.2–93.8]; n=357 vs. 70.9% [65.2–77.1]; n=106; p<0.0001). PPI use was also associated with improved PFS vs. no PPI use after 1 year (95.9% [94.6–97.3]; n=745 vs. 86.4% [82.9–90.1]; n=278) and after 5 years (66.8% [63.0–70.8]; n=286 vs. 45.9% [39.6–53.2]; n=69; p<0.0001).Conclusion:GERD had no effect on survival in SSc or SSc-ILD. PPIs improved survival in patients with SSc-ILD; however, controlled, prospective trials are needed to confirm this finding.Disclosure of Interests:Michael Kreuter Speakers bureau: Boehringer, Consultant of: Boehringer, Grant/research support from: Boehringer, Francesco Bonella Speakers bureau: Boehringer, Roche, GSK, Consultant of: Boehringer, Roche, GSK, Grant/research support from: Boehringer, Kuhr Kathrin: None declared, Jörg Henes Speakers bureau: Abbvie, Boehringer, Chugai, Roche, Janssen, Novartis, SOBI, Pfizer and UCB, Consultant of: Boehringer, Celgene, Chugai, Roche, Janssen, Novartis, SOBI, Grant/research support from: Chugai, Roche, Janssen, Novartis, SOBI, Pfizer, Elise Siegert: None declared, Gabriela Riemekasten Speakers bureau: Novartis, Janssen, Roche, GSK, Boehringer, Consultant of: Janssen, Actelion, Boehringer, Norbert Blank Consultant of: Sobi, Novartis, Roche, UCB, MSD, Pfizer, Actelion, Abbvie, Boehringer, Grant/research support from: Novartis, Sobi, Christiane Pfeiffer: None declared, Ulf Müller-Ladner: None declared, Alexander Kreuter Speakers bureau: MSD, Boehringer, InfectoPharm, Paid instructor for: MSD, PETER KORSTEN Consultant of: Glaxo, Abbvie, Pfizer, BMS, Chugai, Sanofi, Lilly, Boehringer, Novartis, Grant/research support from: Glaxo, Aaron Juche: None declared, Marc Schmalzing Speakers bureau: Chugai Roche, Boehringer, Celgene, Medac, UCB, Paid instructor for: Novartis, Abbvie, Astra Zeneca, Chugai Roche, Janssen, Consultant of: Chugai Roche, Hexal Sandoz, Gilead, Abbvie, Janssen, Boehringer, Margitta Worm Speakers bureau: Boehringer, Ilona Jandova Speakers bureau: Boehringer, Novartis, Abbvie, Laura Susok Speakers bureau: MSD, Novartis, BMS, Sunpharma, Consultant of: MSD, Tim Schmeiser Consultant of: Abbvie, Boehringer, Novartis, UCB, Claudia Guenther Paid instructor for: Advisory Board Boehringer January 2020, Employee of: Novartis 2002-2005, Gernot Keyszer Consultant of: Boehringer, Jan Ehrchen Speakers bureau: Boehringer, Janssen, Chugai, Sobi, Employee of: Pfizer, Actelion (now Janssen), Andreas Ramming Speakers bureau: Boehringer, Gilead, Janssen, Pfizer, Roche, Consultant of: Boehringer, Pfizer, Grant/research support from: Novartis, Pfizer, Ina Kötter Speakers bureau: several companies, Consultant of: several companies, Grant/research support from: several companies, Hanns-Martin Lorenz Speakers bureau: Abbvie, Astra Zeneca, Actelion, Alexion Amgen, Bayer Vital, Baxter, Biogen, Boehringer, BMS, Celgene, Fresenius, Genzyme, GSK, Gilead, Hexal, Janssen, Lilly, Medac, MSD, Mundipharm, Mylan, Novartis, Octapharm, Pfizer, Roche Chugai, Sandoz, Sanofi, Shire SOBI, Thermo Fischer, UCB, Grant/research support from: basic research studies: Pfizer, Novartis, Abbvie, Gilead, Lilly, MSD, Roche Chugai, Pia Moinzadeh Speakers bureau: Boehringer, Actelion, Grant/research support from: Actelion, Nicolas Hunzelmann Speakers bureau: Boehringer Janssen, Roche, Sanofi, Consultant of: Boehringer

Abstract
Background:The immunomodulatory cytokine IL-16 is increased in several inflammatory and autoimmune diseases1. IL-16 recruits and activates CD4+ immune cells such as T cells, dendritic cells, or monocytes. IL-16 is produced by various immune and non-immune cells, but synthesis and storage of IL-16 is regulated differentially depending on the cell type and stimulation. For its biological activity, IL-16 cleavage by caspase-3 is required1. Necrotizing granulomatous inflammation is a hallmark of granulomatosis with polyangiitis (GPA) with neutrophil dysregulation as a central driver of chronic inflammation and autoimmunity2. Earlier studies showed a correlation between increased serum IL-16 and disease parameters in AAV, including GPA3, but functional evidence for a direct link between IL-16 and neutrophils in granulomatous inflammation is missing so far.Objectives:In this study we aim to identify a functional link between increased IL-16, neutrophils, and the autoantigen proteinase 3 (PR3) with regard to chronic inflammation and autoimmunity in GPA.Methods:IL-16 was measured in sera of GPA patients (n = 40) and healthy controls (HC, n = 50) by ELISA and correlated with clinical features, such as disease activity (BVAS), creatinine, GFR, VDI and PR3-ANCA status. IL-16 protein expression was analyzed in peripheral blood mononuclear cells (PBMC) and polymorphonuclear cells (PMN) from GPA patients and HC (n = 5, each) by SDS-PAGE and western blot. Binding affinity of recombinant pro-IL-16 to native human PR3 was assessed by microscale thermophoresis. Cleavage of pro-IL-16 by active human PR3 was performed at various time points at 37°C. Cleavage products were analyzed by SDS-PAGE and western blot.Results:Circulating IL-16 was significantly increased in GPA patients compared to HC. Elevated IL-16 positively correlated with BVAS, creatinine, VDI and PR3-ANCA status and negatively correlated with GFR. In PMBC and PMN from GPA and HC we identified different expression patters of precursor and active forms of IL-16. In healthy PBMC we found high amounts of precursor (80kD), pro-IL-16 (55kD) and active IL-16 (17kD). In contrast, PBMC from GPA patients had lower amounts of pro-IL-16 and no active IL-16, indicating activation and secretion of IL-16 due to inflammatory stimulation, as shown earlier5. In GPA PMN we detected no precursor IL-16, but pro-IL-16 and its active form, in contrast to very low amounts of all IL-16 forms in healthy PMN. Processing and release of IL-16 in neutrophils has been linked to apoptosis and secondary necrosis5. By interaction studies we demonstrated direct binding of pro-IL-16 to PR3 with a Kd of 10 nM. In a subsequent cleavage assay we confirmed IL-16 processing by PR3 in a time-dependent manner.Conclusion:Correlation of serum IL-16 with clinical features of GPA suggests that IL-16 is associated with markers of disease activity, tissue damage and autoreactivity. We showed that PBMC and PMN represent a source of IL-16 in GPA. By the identification of PR3 as an additional IL-16-activating enzyme we could demonstrate a potential link between excessive PR3 expression, cell death and IL-16-dependent mechanisms, contributing to chronic granulomatous inflammation and autoimmunity in GPA.References:[1]Glass, W.

Abstract
Hintergrund Das Raynaud-Phänomen und die damit häufig einhergehenden digitalen Ulzerationen stellen für Patienten mit systemischer Sklerose (Sklerodermie [SSc]) ein frühes und sehr belastendes Symptom mit bedeutenden Einschränkungen der Arbeitsfähigkeit und Lebensqualität dar. Der Einsatz vasoaktiver Medikamente (insbesondere intravenöser Prostazyklinderivate) soll helfen, das Risiko hypoxischer Gewebeschäden bis hin zum Verlust der Finger zu reduzieren. Methoden Um Aufschluss über die aktuelle Versorgung von Patienten mit Prostazyklinderivaten im klinischen Alltag in Deutschland zu erhalten, führten wir eine Umfrage unter den im Deutschen Netzwerk für systemische Sklerodermie (DNSS) zusammengeschlossenen Kliniken durch. Zusätzlich erfolgte eine separate Patientenbefragung über die Sklerodermie Selbsthilfe e. V., die sich nur auf die Symptome „Raynaud-Phänomen“ und „Digitale Ulzera“ und den Einsatz intravenöser Prostazyklinderivate bezog. Ergebnisse Von den befragten 433 Patienten gaben 56 % an, dass sie bereits aufgrund ihrer Erkrankung und Symptome mit Prostazyklinderivaten behandelt wurden. Insgesamt 61 % erhielten die Therapie aufgrund starker Raynaud-Symptomatik und 39 % aufgrund digitaler Ulzerationen. Die meisten Befragten erfuhren durch die Therapie nicht nur eine Verbesserung des Raynaud-Phänomens und der digitalen Ulzera, sondern auch eine wesentliche Verbesserung von Einschränkungen im Alltag. Sie gaben zudem an, wesentlich weniger fremde Hilfe in Anspruch genommen sowie wesentlich weniger Fehlzeiten bei der Arbeit gehabt zu haben. Schlussfolgerung Die Patienten empfanden durchweg einen positiven Effekt der Therapie mit Prostazyklinderivaten auf das Raynaud-Phänomen, ihre digitalen Ulzerationen, Schmerzen und Alltagseinschränkung und fühlten sich durch die stationäre Therapie gut und sicher betreut. Diese positiven Effekte in der Patientenwahrnehmung sind eine eindrückliche Stütze und bestätigen nachdrücklich die auf europäischer und internationaler Ebene erarbeiteten Therapieempfehlungen.

Abstract
Background Digital ulcers (DU) present a challenging complication in systemic sclerosis (SSc). The aim of this study was to combine clinical characteristics and imaging methods to a composite score for the prediction of DU in SSc patients. Methods Seventy-nine SSc patients received clinical examination, their patient history was taken and nailfold capillaroscopy (NC), colour Doppler ultrasonography (CDUS) and fluorescence optical imaging (FOI) of the hands were performed at baseline. Newly developed DU over a period of approximately 12 months were registered. We used criteria with area under the curve (AUC) of at least 0.6 in regard to the development of these new DU to create the score (CIP-DUS, clinical features, imaging, patient history—digital ulcer score). Results Twenty-nine percent of all SSc patients developed new DU during follow-up (48.1% diffuse, 18.4% limited SSc). Based on the cross-validated (cv) AUC, a weight (cvAUC > 0.6 and ≤ 0.65: 1; cvAUC > 0.65 and ≤ 0.7: 2; cvAUC > 0.7: 3) was assigned to each selected parameter. The performance of the final CIP-DUS was assessed with and without the CDUS/FOI component. For the scleroderma patterns in NC, three points were appointed to late, two to active and one point to early capillaroscopy pattern according to Cutolo et al. The CIP-DUS including the CDUS and FOI parameters resulted in a good diagnostic performance (AUC after cross-validation: 0.83, 95%CI 0.74 to 0.92) and was well calibrated (chi-square = 12.3, p = 0.58). The cut-off associated with the maximum of sensitivity and specificity was estimated at ≥ 10 points resulting in a sensitivity of 100% and specificity of 74% for new DU during follow-up. Excluding CDUS and FOI parameters leads to a non-statistically significant lower performance (AUC after cross-validation: 0.81, 95%CI 0.72 to 0.91). However, including CDUS and FOI resulted in a better classification of patients in respect to the outcome new DU in follow-up due to significantly better reclassification performance (NRI = 62.1, p = 0.001) and discrimination improvement (IDI = 9.7, p = 0.01). Conclusion A new score was introduced with the aim to predict digital ulcers. If applied correctly and with the new imaging techniques proposed, all patients at risk of digital ulcers throughout 12 months could be identified.

Abstract
Background:In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in forced vital capacity (FVC) over 52 weeks. Elevated CRP is a marker of an inflammatory phenotype and has been associated with a greater rate of decline in FVC and higher mortality in patients with SSc.Objectives:To assess the effects of nintedanib in subgroups by CRP at baseline in the SENSCIS trial.Methods:Patients with SSc-ILD with onset of first non-Raynaud symptom <7 years and ≥10% fibrosis of the lungs on HRCT were randomised to receive nintedanib or placebo. We analysed the rate of decline in FVC (mL/year) over 52 weeks, the proportion of patients with an absolute increase in FVC ≥3% predicted (proposed as the minimal clinically important difference for improvement in FVC in patients with SSc-ILD), and absolute change from baseline in mRSS at week 52 in subgroups with normal vs elevated high-sensitivity CRP (≤4.99 vs >4.99 mg/L) at baseline.Results:Of patients with available data, 78/270 (28.9%) and 74/261 (28.4%) in the nintedanib and placebo groups, respectively, had CRP >4.99 mg/L at baseline. Compared with patients with lower CRP, those with CRP >4.99 mg/L included a similar proportion of patients who were ATA-positive (61.8% vs 60.2%, respectively), a greater proportion with diffuse cutaneous SSc (63.2% vs 49.3%) and had a higher mean mRSS (13.7 vs 10.2) and lower mean FVC % predicted (68.6% vs 73.9%). The adjusted annual rate of decline in FVC in the placebo group was numerically greater in patients with CRP >4.99 than ≤4.99 mg/L at baseline (-106.6 [SE 27.6] vs -83.0 [17.1] mL/year). The effect of nintedanib vs placebo on reducing the rate of decline in FVC was numerically more pronounced in patients with CRP >4.99 than ≤4.99 mg/L at baseline but the treatment-by-time-by-subgroup interaction p-value did not indicate heterogeneity in the effect of nintedanib between subgroups (p=0.70) (Figure). In the nintedanib and placebo groups, respectively, the proportions of patients with an absolute increase in FVC ≥3% predicted at week 52 were 20.4% and 15.0% in those with CRP ≤4.99 mg/L and 24.4% and 14.9% in those with CRP >4.99 mg/L at baseline (treatment-by-subgroup interaction p=0.59); adjusted mean changes in mRSS at week 52 were -2.2 (SE 0.3) and -2.1 (0.3) in those with CRP ≤4.99 mg/L (difference -0.1 [95% CI -1.0, 0.8]) and -2.3 (0.5) and -1.0 (0.5) in those with CRP >4.99 mg/L at baseline (difference -1.2 [-2.7, 0.2]; treatment-by-visit-by-subgroup interaction p=0.20).Conclusion:In the SENSCIS trial, the rate of decline in FVC over 52 weeks in the placebo group was numerically greater in patients with elevated CRP at baseline. Nintedanib reduced the rate of decline in FVC both in patients with normal and elevated CRP at baseline, with a numerically greater effect in patients with elevated CRP.Disclosure of Interests:Gabriela Riemekasten Consultant of: Cell Trend GmbH, Janssen, Actelion, Boehringer Ingelheim, Speakers bureau: Actelion, Novartis, Janssen, Roche, GlaxoSmithKline, Boehringer Ingelheim, Pfizer, Patricia Carreira Grant/research support from: Actelion, Roche, MSD, Consultant of: GlaxoSmithKline, VivaCell Biotechnology, Emerald Health Pharmaceuticals, Boehringer Ingelheim, Roche, Speakers bureau: Actelion, GlaxoSmithKline, Roche, Lesley Ann Saketkoo Grant/research support from: Corbus Pharmaceuticals, United Therapeutics, Consultant of: Boehringer Ingelheim, Eicos Sciences, Speakers bureau: Boehringer Ingelheim, Martin Aringer Consultant of: Boehringer Ingelheim, Roche, Speakers bureau: Boehringer Ingelheim, Roche, Lorinda Chung Grant/research support from: United Therapeutics, Boehringer Ingelheim, Consultant of: Bristol-Myers Squibb, Boehringer Ingelheim, Mitsubishi Tanabe, Eicos Sciences, Janet Pope Grant/research support from: AbbVie, Bristol-Myers Squibb, Eli Lilly & Company, Merck, Roche, Seattle Genetics, UCB, Consultant of: AbbVie, Actelion, Amgen, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Eicos Sciences, Eli Lilly & Company, Emerald, Gilead Sciences, Inc., Janssen, Merck, Novartis, Pfizer, Roche, Sandoz, Sanofi, UCB, Speakers bureau: UCB, Corinna Miede Employee of: Employee of Boehringer Ingelheim, Susanne Stowasser Employee of: Employee of Boehringer Ingelheim, Martina Gahlemann Employee of: Employee of Boehringer Ingelheim, Margarida Alves Employee of: Employee of Boehringer Ingelheim, Dinesh Khanna Shareholder of: Eicos Sciences, Inc./Civi Biopharma, Inc., Grant/research support from: Dr Khanna was supported by NIH/NIAMS K24AR063120, Consultant of: Acceleron, Actelion, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Corbus Pharmaceuticals, Horizon Therapeutic, Galapagos, Roche/Genentech, GlaxoSmithKline, Mitsubishi Tanabe, Sanofi-Aventis/Genzyme, UCB

Abstract
Background:Gastroesophageal reflux (GER) is common in SSc and thus treatment with anti-acid therapy (AAT) is frequent. An association between GER and the development / progression of SSc-ILD has been hypothesized. However, outcomes of AAT on disease progression in SSc-ILD has only sparsely been studied.Objectives:Methods:The German Network for Systemic Scleroderma (DNSS), which includes SSc pts. prospectively, was analyzed for SSc-ILD. Those without progression at ILD 1stdiagnosis were categorized in AAT vs. no-AAT users and disease outcome was assessed.Results:SSc-ILD was reported in 1165 (28.2%) out of 4131 pts. 712 of SSc-ILD pts had no disease progression at ILD 1stdiagnosis. 567 used AAT while 145 did not. Baseline characteristics were similar between groups with regards to age (mean 54.7 years), BMI, time since SSc diagnosis and immunosuppressant use. Significant differences in no-AAT vs. AAT were found for gender (male 18% vs. 25%, p=0.05), SSc subtype (p=0.002, diffuse more common in AAT), lung function (DLCO 66% vs. 58%, p=0.001; FVC 86% vs. 77%, p=0.001), mRSS (8 vs. 11.5, p<0.01), esophageal involvement (32% vs. 56%, p<0.01) and steroid use (30% vs. 43%, p=0.005). While mortality did not differ between groups (3.9%, p= 0.59), disease progression was more common in the AAT group than in no-AAT users (24.5% vs. 13%, p=0.03). Furthermore, there was a significant difference in decline of FVC≥10% with 30% in the AAT compared to 14% in no-AAT (p=0.018); a decline in DLCO≥15% was more common in the AAT group by trend (23% vs. 14%, p=0.087).Conclusion:While results may have partially been biased by differences in baseline characteristics, this current analysis disfavors the approach of AAT use for SSc-ILD.Disclosure of Interests:Michael Kreuter Grant/research support from: Roche, Boehringer, Consultant of: Roche, Boehringer, Speakers bureau: Boehringer, Roche, Francesco Bonella Grant/research support from: Boehringer, Consultant of: Boehringer, Roche, Bristol MS, Galapagos, Speakers bureau: Boehringer, Roche, Gabriela Riemekasten Consultant of: Cell Trend GmbH, Janssen, Actelion, Boehringer Ingelheim, Speakers bureau: Actelion, Novartis, Janssen, Roche, GlaxoSmithKline, Boehringer Ingelheim, Pfizer, Ulf Müller-Ladner Speakers bureau: Biogen, Jörg Henes Grant/research support from: Novartis, Roche-Chugai, Consultant of: Novartis, Roche, Celgene, Pfizer, Abbvie, Sanofi, Boehringer-Ingelheim,, Elise Siegert Grant/research support from: Actelion, Consultant of: AEC, Speakers bureau: NA, Claudia Guenther: None declared, Ina Koetter Grant/research support from: Novartis, Roche, Speakers bureau: Abbvie, Actelion, Celgene, MSD, UCB, Sanofi, Lilly, Pfizer, Novartis, Chugai, Roche, Boehringer, Norbert Blank Speakers bureau: Actelion, Roche, Boehringer, Pfizer, Chugai, Christiane Pfeiffer: None declared, Marc Schmalzing: None declared, Gabriele Zeidler: None declared, PETER KORSTEN Grant/research support from: Novartis, Juarms GmbH, Consultant of: Abbvie, Pfizer, Lilly, BMS, Speakers bureau: Abbvie, Pfizer, chugai, BMS, Lilly, Sanofi aventis, Laura Susok: None declared, Aaron Juche: None declared, Margitta Worm Consultant of: Mylan Gemany, Bencard Allergie, BBV Technologies S.A., Novartis, Biotest, Sanofi, Aimmune Therapies, Regeneron, Speakers bureau: ALK-Abello, Novartis, Sanofi, Biotest, Mylan, Actelion, HAL Allergie, Aimmune Bencard Allergie, Ilona Jandova: None declared, Jan Ehrchen: None declared, Cord Sunderkoetter: None declared, Gernot Keyszer: None declared, Andreas Ramming Grant/research support from: Pfizer, Novartis, Consultant of: Boehringer Ingelheim, Novartis, Gilead, Pfizer, Speakers bureau: Boehringer Ingelheim, Roche, Janssen, Tim Schmeiser Speakers bureau: Actelion, UCB, Pfizer, Alexander Kreuter Speakers bureau: Sanofi, Abbvie, Merck Sharp&Dohme, Boehringer, Kathrin Kuhr: None declared, Hanns-Martin Lorenz Grant/research support from: Consultancy and/or speaker fees and/or travel reimbursements: Abbvie, MSD, BMS, Pfizer, Celgene, Medac, GSK, Roche, Chugai, Novartis, UCB, Janssen-Cilag, Astra-Zeneca, Lilly.

Abstract
Background:In the SENSCIS trial, nintedanib reduced the progression of SSc-ILD vs placebo, as shown by a lower rate of decline in forced vital capacity (FVC). The adverse event (AE) profile of nintedanib was characterised mainly by gastrointestinal (GI) events, including weight loss.Objectives:Assess FVC decline and AEs in subgroups by weight loss ≤5% vs >5% over 52 weeks in the SENSCIS trial.Methods:Patients with SSc-ILD with first non-Raynaud symptom <7 years before screening and ≥10% fibrosis of the lungs on an HRCT scan were randomised to nintedanib or placebo. In a non-randomised comparison, we analysed the rate of decline in FVC (mL/year) and AEs over 52 weeks in subgroups by weight loss (≤5% vs >5%) over 52 weeks.Results:In the nintedanib (n=288) and placebo (n=288) groups, respectively, 112 (38.9%) and 43 (14.9%) patients had weight loss >5% over 52 weeks. At baseline, patients with weight loss >5% over 52 weeks had a higher mean age (57.0 vs 52.9 years), greater proportion of females (81.3% vs 72.9%), and similar mean BMI (26.5 vs 25.7 kg/m2, respectively) and FVC % predicted (71.0% vs 73.1%, respectively) vs patients with weight loss ≤5%. In the placebo group, the mean (SE) annual rate of decline in FVC was similar between patients who had weight loss ≤5% and >5% over 52 weeks (-92.7 [14.7] mL/year and -96.4 [34.9] mL/year, respectively). The estimated annual rate of decline in FVC was lower in patients treated with nintedanib than placebo, with between-group differences in patients who had weight loss ≤5% and >5% of 49.9 mL/year [95% CI 4.2, 95.6]) and 30.2 mL/year [95% CI -50.5, 110.9]), respectively, with no evidence of heterogeneity between subgroups by weight loss (p=0.68 for interaction). Standardised differences in baseline values of potential confounders were <0.2 (indicating negligible differences). The most frequent AEs in patients treated with nintedanib were diarrhoea (74.4% and 77.7% of patients with weight loss ≤5% and >5%, respectively), nausea (30.1% and 33.9%, respectively) and vomiting (19.3% and 33.3%, respectively). In the nintedanib and placebo groups, respectively, AEs leading to discontinuation of study drug occurred in 17.0% and 8.6% of patients with weight loss ≤5%, and 14.3% and 9.3% of patients with weight loss >5% over 52 weeks.Conclusion:In the SENSCIS trial in patients with SSc-ILD, a greater proportion of patients treated with nintedanib than placebo had weight loss >5% over 52 weeks. The rate of decline in FVC was numerically lower in the nintedanib group than in the placebo group both in patients with weight loss ≤5% and >5% over 52 weeks. AEs leading to discontinuation of nintedanib were not more frequent in patients with weight loss >5% vs ≤5%.References:Disclosure of Interests: :Alain LESCOAT: None declared, Stéphane Jouneau Grant/research support from: AIRB, Boehringer Ingelheim, LVL Medical, Novartis, Roche, Bellorophon Therapeutics, Biogen, Fibrogen, Galecto Biotech, Gilead Sciences, Pharm-Olam, Pliant Therapeutics, Savara Pharmaceuticals/Serendex Pharmaceuticals, Consultant of: Actelion, AIRB, AstraZeneca, Bristol-Myers Squibb, Boehringer Ingelheim, Chiesi, Genzyme, GlazoSmithKline, LVL Medical, Mundipharma, Novartis, Pfizer, Roche, Sanofi, Bruno Crestani Grant/research support from: AstraZeneca, Bristol-Myers Squibb, Boehringer Ingelheim, Novartis, Roche, Sanofi, Consultant of: AstraZeneca, Bristol-Myers Squibb, Boehringer Ingelheim, Roche, Sanofi, Speakers bureau: AstraZeneca, Boehringer Ingelheim, Roche, Sanofi, Gabriela Riemekasten Consultant of: Cell Trend GmbH, Janssen, Actelion, Boehringer Ingelheim, Speakers bureau: Actelion, Novartis, Janssen, Roche, GlaxoSmithKline, Boehringer Ingelheim, Pfizer, Yasuhiro Kondoh Consultant of: Boehringer Ingelheim, Asahi Kasei Pharma, Janssen, Shionogi, Speakers bureau: Boehringer Ingelheim, Asahi Kasei Pharma, Janssen, Eisai, KYORIN, Mitsubishi Tanabe Pharma, Novartis, Shionogi, Vanessa Smith Grant/research support from: The affiliated company received grants from Research Foundation - Flanders (FWO), Belgian Fund for Scientific Research in Rheumatic diseases (FWRO), Boehringer Ingelheim Pharma GmbH & Co and Janssen-Cilag NV, Consultant of: Boehringer-Ingelheim Pharma GmbH & Co, Speakers bureau: Actelion Pharmaceuticals Ltd, Boehringer-Ingelheim Pharma GmbH & Co and UCB Biopharma Sprl, Nina Patel Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Speakers bureau: Genentech, John Huggins Consultant of: I was a site PI for the SENSCIS trial for Boehringer Ingelheim, Christian Stock Employee of: Employee of Boehringer Ingelheim, Martina Gahlemann Employee of: Employee of Boehringer Ingelheim, Margarida Alves Employee of: Employee of Boehringer Ingelheim, Christopher Denton Grant/research support from: GlaxoSmithKline, CSL Behring, and Inventiva, Consultant of: Medscape, Roche-Genentech, Actelion, GlaxoSmithKline, Sanofi Aventis, Inventiva, CSL Behring, Boehringer Ingelheim, Corbus Pharmaceuticals, Acceleron, Curzion and Bayer

Abstract
Background:Granulomatosis with polyangiitis (GPA) is characterized by extravascular necrotizing granulomatous inflammation and systemic ANCA – associated (AAV) vasculitis with neutrophils as a key player in the pathogenesis (1). We and others have shown that neutrophil-related cell death mechanisms contribute to chronic inflammatory processes in AAV (2, 3). Recently, another form of inflammatory cell death primarily described in monocytes called pyroptosis was also discovered in neutrophils (4). A cardinal feature of pyroptosis is the activation of the NLRP3 inflammasome, a sensor of different pathogen- and damage-associated molecular patterns (PAMP, DAMP), following caspase-1-mediated processing and secretion of IL-1beta (5).Objectives:The aim of this study was to investigate, if neutrophils from GPA patients express pyroptosis-related components NLRP3, active caspase 1 and cleaved IL-1beta.Methods:Polymorphonuclear leukocytes (PMN) were isolated from peripheral blood of GPA patients and healthy controls (HC) (n = 10 each). Expression of NLRP3, inactive/active caspase 1 and active IL-1beta was determined by western blot. In addition, peripheral blood mononuclear cells (PBMC) were isolated from GPA and HC. mRNA expression ofnlrp3andil1bwas determined by qPCR. To exclude false-positive results by contamination with monocytes we performed flow cytometry analysis of whole blood samples with markers CD3, CD14, CD15, CD66b and NLRP3.Results:PMN from GPA patients showed markedly increased expression of NLRP3, active caspase 1 and active IL-1beta compared to HC. In contrast, there was no difference between GPA and HC on the mRNA level of neithernlrp3noril1bin PBMC. In addition, we confirmed by flow cytometry increased expression of NLRP3 in PMN from GPA, but not in monocytes.Conclusion:Here we provide evidence, that neutrophils from GPA undergo pyroptosis, demonstrated by increased NLRP3, active caspase 1 expression as well as IL-1beta processing. Neutrophils are present in high numbers at the site of granulomatous lesions of inflamed tissue in GPA and IL-1beta is increased in GPA sera (2). Therefore, neutrophils represent a potential source of IL-1beta in GPA. Given the fact that GPA-associated features such as massive release of necrosis-related DAMP or microbial agents such asStaphylococcus aureus(6) can activate the NLRP3-inflammasome, we identified here a potential relevant mechanism of neutrophils contributing to chronic inflammation of GPA.References:[1]Jennette, J.C., and Falk, R.J.

Abstract
Background:Activation of the alternative and final common pathways have been shown in ANCA-associated vasculitis (AAV) (1). Circulating titers of C5a are elevated and correlate with disease activity in AAV. Binding to the corresponding G protein-coupled receptor (GPCR) C5aR1 enhances the influx of neutrophils, leading to ROS generation and severe necrotizing of vascular walls (2). Moreover, subsequent interaction of C5a with C5aR1 may represent a proinflammatory amplification loop (3). Blocking of the receptor is protective in a murine model in AAV (4). In humans, avacopan, a C5aR1-inhibitor showed promising results as glucocorticoid-sparing agent in two randomized phase II and one ongoing phase III clinicals trials in AAV (NCT02994927). Notably, disease-specific anti-GPCR autoantibody (aab) signatures have been found in different autoimmune diseases (5).Objectives:The aim of the present study was to examine whether (patho)physiological anti-C3aR and anti-C5aR1 aabs correlate with clinical findings in AAV, and whether this is linked to the clinical outcome.Methods:Sera and plasma of AAV patients [granulomatosis with polyangiitis (GPA), n=64; microscopic polyangiitis (MPA), n=26; eosinophilic granulomatosis with polyangiitis (EGPA), n=11] were measured by Elisa for circulating autoantibodies against complement receptors C3a (anti-C3aR aab) and C5a (anti-C5aR1 aab) and plasma levels of C3a and C5a. Expression of C3aR and C5aR1 on T-cells was determined using flow cytometry. Clinical data were assessed at the time of serum sampling and during follow-up for 48 monthsResults:GPA displayed low titers of anti-C3aR aab (GPA:5.33±2.54vs. HD:6.47±2.61, P=0.0031). Anti-C5aR1 aab were decreased in AAV, especially in GPA (GPA:1.02±1.07vs. HD:6.63±2.91, P=<0.0001). Plasma levels of C5a and anti-C5aR aab yielded an inverse correlation in AAV (r=-0.6813, P=0.0127). C5aR1 expression was increased on T-cells in GPA (CD4+C5aR1+T-cells: GPA:10.76±2.55%vs. HD:3.44±0.68%, P=0.0021; CD8+C5aR1+T-cells GPA:9.74±2.10%vs.HD:4.11±0.92%, P=0.0198). Reduced titers of anti-C5aR1 aab <0.45U/ml displayed an increased relapse risk for major organ involvement in GPA (HR 12.85, P=0.0014).Conclusion:As potential diagnostic marker, anti-C5aR1 aab titer may additionally be useful to monitor disease activity in AAV.References:[1]Chen M et al.Complement deposition in renal histopathology of patients with ANCA-associated pauci-immune glomerulonephritis.Nephrol Dial Transpl. 2009;24:1247-1252[2]Schreiber A et al.C5a receptor mediates neutrophil activation an ANCA-induced glomerulonephritis.J Am Soc Nephrol. 2009; 20:289-298[3]Lamprecht P et al.: Pathogenetic and clinical aspects of Anti-Neutrophil Cytoplasmic Autoantibody-associated vasculitides.Front Immunol.2018 Apr 9;9-680[4]Xiao H et al.C5a receptor (CD88) blockade protects against MPO-ANCA GN.J Am Soc Nephrol. 2014;25(2):225-31[5]Klapa S et al.

Abstract
Background:Regulatory IgG autoantibodies directed against diverse G protein-coupled receptors (GPCR),i.e.antibodies with agonistic or antagonistic activity are abundant in human serum. The serum titers of autoantibodies targeting angiotensin II receptor 1 (AT1) and endothelin receptor A (ETA) are specifically altered in autoimmune diseases such as systemic sclerosis (SSc). Disease-promoting mechanisms regulated by anti-AT1and anti-ETAIgG are still elusive, but induction of pro-inflammatory and pro-fibrotic chemokines (CXCL8, CCL18) has been suggested to be one of them.Objectives:To determine the cytokine and phospho-kinase profiles induced in monocyte-like cells by IgG derived from SSc patients (SSc-IgG) enriched with anti-AT1and anti-ETAantibodies in comparison to IgG derived from healthy donors (IgG-HD).Methods:A monocyte-like cell line (THP-1) was culturedin vitroand stimulated with IgG (1 mg/ml) derived from SSc patients or HD in the presence of various inhibitors/blockers for 24h. Then, supernatants were analyzed by a human cytokine/chemokine array. Data were analyzed using bio-mathematical tools such as generalized t-test including the robust regression method from R/Bioconductor package LIMMA. In addition, THP-1 cells were culturedin vitroand stimulated with IgG (1 mg/ml) derived from SSc patients or HD for up to 30 minutes. Thereafter, cell lysates were assayed for the kinome employing a human phospho-kinase array. To validate potential effects of transcription factor inhibition, release of CXCL8 and CCL18 into the supernatant was measured by Elisa.Results:In general, SSc-IgG induced the release of most cytokines by THP-1 cells more pronouncedly than HD-IgG. The bio-mathematical analysis suggested that stimuli, responsible for the shift of the THP-1 cell cytokine profile, are more abundant in SSc-IgG than in HD-IgG. Based upon these findings a gene set enrichment analysis for transcription factors yielded the transcription factors NF-κB, AP-1, and PRDM1 (Blimp-1) as putative major regulatory hubs for the response of THP-1 cells to SSc-IgG. Further, SSc-IgG altered the phosphorylation status of several proteins, indicative of an involvement of MAPK and/or JAK/STAT pathways. Interestingly, a role for AP-1 was also proposed by the inhibition of CXCL8 and CCL18 release following pretreatment of THP-1 cells with an AP-1 blocker.Conclusion:Herein, we demonstrate that IgG of SSc patients, enriched with anti-AT1and anti-ETAautoantibodies drives THP-1 cells towards a general pro-inflammatory and pro-fibrotic phenotype, which is reflected by broad changes in the secretome and kinome of these cells. Furthermore, our results highlight AP-1 as critical regulator of gene transcription of CXCL8 and CCL18 in a monocyte-like cell line.References:[1]Cabral-Marques O, Marques A, Giil LM, De Vito R, Rademacher J, Günther J, Lange T, Humrich JY, Klapa S, Schinke S, et al.

Abstract
Background:Micro-RNAs (miRNA) are short non-coding RNAs that regulate inflammation mostly by translational repression. Previously, we screened 847 miRNAs in nasal tissue from GPA patients and found a disease associated alteration of miRNA expression compared to healthy controls and chronic rhinosinusitis. MiR-184 was most over expressed in nasal tissue from GPA (13.4x). The dual-luciferase reporter assay confirmed a significant reduction of Proteinase-3 (PRTN3) expression by miR-184 (1).PRTN3 transcripts with an alternative 3’ untranslated region (UTR) have been described in GPA (2). The pathophysiological relevance of this alternative transcript remains unclarified.Objectives:To identify new miRNA targets of potential pathophysiological relevance in GPA, we validated the effect of the 21 most dysregulated miRNAs on the mRNA of PRTN3. Further, we included the alternative PRTN3 mRNA in our screen to look for new regulatory differences.Methods:The inhibitory capacity of miRNAs on Proteinase-3 mRNA was estimated by a dual-luciferase reporter system. The sequences of the alternative (132bp longer) and the regular 3’UTR-PRTN3 were cloned and inserted into the pmirGLO vector and co-transfected with 21 miRNA mimics into HeLa cells. Co-transfection withCaenorhabditis elegansmiRNA 67 mimic (cel-miR-67) was used as negative control. Statistical significance was evaluated by students t-test adjusted for multiple comparisons (Holm-Sidak).Results:For 18 of 21 investigated miRNAs no effects could be observed on the alternative and the regular 3’UTR-PRTN3. But there were remarkable differential effects of let-7f, miR-184 and miR-708. Let-7f (-29,2%) and miR-708 (-23,6%) both showed a suppression of the alternative 3’UTR-PRTN3 but no effect on the regular 3’UTR-PRTN3 while miR-184 only suppressed the regular 3’UTR (-17,5 %) and not the alternative variant (fig. 1-2).Fig. 1.Dual-luciferase reporter assay with the regular 3’UTR of PRTN3 cloned into the pmirGLO vector compared to empty vector (NTC). Significant effect for miR-184 (17,5 %), miR-708 no effect and let-7f small but not significant reduction in luciferase activity (12,3 %). Data represent 3 independent experiments with triplicate measurements. miR-184 was tested 6 times. *P<0.05; ns = not significant; error bars display standard deviation.Fig. 2.Dual-luciferase reporter assay with the alternative 3’UTR of PRTN3. Significant effects of let-7f (29,2 %) and miR-708 mimic (23,6 %) but no significant effects of miR-184 of luciferase activity. 3 independent experiments with triplicate measurements. *P<0.05Conclusion:Disease specific miRNA signatures together with an increased PRTN3 level and in alternative PRTN3 mRNA in GPA suggest a dysregulation of PRTN3 expression in GPA. To our knowledge this is the first analysis in GPA showing that miRNAs can differentially regulate the expected and the alternative 3’UTR variants of PRTN3-mRNA. As miR-184 is markedly upregulated in GPA, a repression of PRTN3 is to be anticipated, possibly as a reaction to previous neutrophil activation with PRTN3 overexpression. Our findings also strengthen the potential pathophysiological role of the alternative PRTN3 mRNA.References:[1]Schinke S et alPROTEINASE-3 REGULATING MICRO-RNA IN GRANULOMATOSIS WITH POLYANGIITIS.

Abstract
Background:Systemic sclerosis (SSc) is an autoimmune disorder with chronic and persistent inflammation. Interleukin-16 was originally described as a factor that could attract activated T cells in humans [1]. Elevated amounts of IL-16 have been demonstrated in SSc [2].Objectives:This study was undertaken to find out if IL-16 is associated with clinical characteristics of SSc.Methods:IL-16 was measured by Elisa in serum of patients with SSc (n=119) and healthy controls (n=50). Further, the presence of active IL-16 in mononuclear cells from peripheral blood of SSc patients (n=10) was examined by Western blot. Statistical analyses were done employing Graph Pad prism software (v 8). Patients with SSc were characterized based upon epidemiological and clinical parameters.Results:The serum concentration of IL-16 was higher in patients with SSc than in healthy controls (272.7±165.4 vs 172.8±64.84 pg/ml, p<0.0001). Further, the difference in the IL-16 serum concentration was more prominent in females (265.6±174.2 vs 160.1±53.37 pg/ml, p=0.0002) than in males (287.1±144.1 vs 187.6±74.64 pg/ml, p=0.0034). In addition, the concentration of IL-16 was elevated in patients with diffuse SSc compared to limited SSc (p=0.0206). The concentration of IL-16 in serum of SSc patients positively correlated with CRP (n=115, r=0.49, p<0.0001). There was a weak positive correlation between IL-16 in serum of SSc patients and the mRSS (n=112, r=0.22, p=0.0175). Noteworthy, the concentration of IL-16 was heightened in SSc patients with lung fibrosis compared to SSc patients without lung fibrosis (p=0.009). The ROC value of SSc patients with lung fibrosis was 0.64 (95%CI: 0.58-0.83). Moreover, active IL-16 derived from peripheral blood mononuclear cells (PBMC) of SSc patients with lung fibrosis was present in higher amounts compared to PBMC of SSc patients without lung fibrosis (5 vs 5, p=0.0557).Conclusion:Our results confirm and extend previous data by showing not only an increased concentration of IL-16 in the circulation of SSc patients, but new findings pointing towards a role of IL-16 for contributing to lung fibrosis in SSc.References:[1]Cruikshank, W. and D.M.

Abstract
Objectives To investigate the effect of ACE inhibitors (ACEi) on the incidence of scleroderma renal crisis (SRC) when given prior to SRC in the prospectively collected cohort from the European Scleroderma Trial and Research Group (EUSTAR). Methods SSc patients without prior SRC and at least one follow-up visit were included and analyzed regarding SRC, arterial hypertension, and medication focusing on antihypertensive medication and glucocorticoids (GC). Results Out of 14,524 patients in the database, we identified 7648 patients with at least one follow-up. In 27,450 person-years (py), 102 patients developed SRC representing an incidence of 3.72 (3.06–4.51) per 1000 py. In a multivariable time-to-event analysis adjusted for age, sex, disease severity, and onset, 88 of 6521 patients developed SRC. The use of ACEi displayed an increased risk for the development of SRC with a hazard ratio (HR) of 2.55 (95% confidence interval (CI) 1.65–3.95). Adjusting for arterial hypertension resulted in a HR of 2.04 (95%CI 1.29–3.24). There was no evidence for an interaction of ACEi and arterial hypertension (HR 0.83, 95%CI 0.32–2.13, p = 0.69). Calcium channel blockers (CCB), angiotensin receptor blockers (ARB), endothelin receptor antagonists, and GC—mostly in daily dosages below 15 mg of prednisolone—did not influence the hazard for SRC. Conclusions ACEi in SSc patients with concomitant arterial hypertension display an independent risk factor for the development of SRC but are still first choice in SRC treatment. ARBs might be a safe alternative, yet the overall safety of alternative antihypertensive drugs in SSc patients needs to be further studied.

Abstract
Objective: Vasculopathy in systemic sclerosis (SSc) is characterized by the obliteration of arterioles and a reduced capillary density in various tissues. In SSc, atrophic alterations of the choroid have been suggested based on morphological data acquired by optical coherence tomography (OCT). In this study, we aimed to assess the choroid in eyes of patients with SSc from a microcirculatory, dynamic point of view by adding optical coherence tomography angiography (OCTA) to the diagnostic spectrum.Method: SSc patients were enrolled, and age- and gender-matched healthy subjects were used as controls. In addition to basic ophthalmological and rheumatological examinations, individuals underwent enhanced-depth imaging OCT and OCTA. Subfoveal thicknesses of the choroid as well as all three choroidal vascular sublayers were measured and submacular perfusion values were evaluated.Results: In total, 12 patients with SSc and 12 matched controls were included. The median age of participants was 64 years. Submacular perfusion was significantly lower in the choriocapillaris (Δ = 0.72%; p = 0.045), Sattler's layer (Δ = 2.87%; p = 0.001), and Haller's layer (Δ = 2.69%; p = 0.018) of SSc patients compared to controls. Subfoveal thicknesses of Sattler's layer (Δ = 15 µm; p = 0.026) and Haller's layer (Δ = 41 µm; p = 0.045) were also significantly smaller in the SSc group.Conclusion: Choroidal microcirculation is impaired in SSc, even in patients without ophthalmological symptoms. Choroidal OCT and OCTA may offer additional biomarkers for SSc activity.

Abstract
Objective Systemic sclerosis (SSc) can lead to ischemic complications such as digital ulcers (DUs). The aim of the study was to find predictors of DUs by clinical and new imaging methods. Patients and methods All 79 SSc patients included in the study received a clinical, colour Doppler ultrasound (CDUS), fluorescence optical imaging (FOI) and capillaroscopy examination at baseline, and their capacity to predict new DU development was analysed in 76 patients at 12 months follow-up. Results Twenty-two of 76 patients (28.9%) developed new ulcers during follow-up (diffuse SSc 48.1%; limited SSc 18.4%). Receiver operating characteristic (ROC) curve analysis revealed an area under the curve of 0.7576 for DU development, with a specificity of 87% and a sensitivity of 54.6% (p = 0.0003, OR = 8.1 [95%CI 2.5–25.6]) at a cut-off of ≥ 21 points (ACR/EULAR classification criteria for SSc). Capillaroscopy and CDUS had high sensitivity (100% and 95.5%) but low specificity (28.9% and 22.2%) for ulcer occurrence when used alone, but better specificity (46.3%) when combined (OR = 18.1 [95%CI 2.3–144.4]; p = 0.0004). Using FOI, fingers with pathologic staining had a higher risk for new ulcer development in the same finger (p = 0.0153). General future DU (i.e. DU also in other fingers) was associated with a missing FOI signal in the right digit III at baseline (p = 0.048). Conclusion New imaging modalities can predict digital ulcer development in SSc patients with high sensitivity for capillaroscopy and CDUS and enhanced specificity when combined. A missing signal of FOI in the right digit III at baseline was associated with general future DU.

Abstract
BACKGROUND A consensus on digital ulcer (DU) definition in systemic sclerosis (SSc) has been recently reached (Suliman et al., J Scleroderma Relat Disord 2:115-20, 2017), while for their evaluation, classification and categorisation, it is still missing. The aims of this study were to identify a set of essential items for digital ulcer (DU) evaluation, to assess if the existing DU classification was useful and feasible in clinical practice and to investigate if the new categorisation was preferred to the simple distinction of DU in recurrent and not recurrent, in patients with systemic sclerosis (SSc). METHODS DeSScipher is the largest European multicentre study on SSc. It consists of five observational trials (OTs), and one of them, OT1, is focused on DU management. The DeSScipher OT1 items on DU that reached ≥ 60% of completion rate were administered to EUSTAR (European Scleroderma Trials and Research group) centres via online survey. Questions about feasibility and usefulness of the existing DU classification (DU due to digital pitting scars, to loss of tissue, derived from calcinosis and gangrene) and newly proposed categorisation (episodic, recurrent and chronic) were also asked. RESULTS A total of 84/148 (56.8%) EUSTAR centres completed the questionnaire. DeSScipher items scored by ≥ 70% of the participants as essential and feasible for DU evaluation were the number of DU defined as a loss of tissue (level of agreement 92%), recurrent DU (84%) and number of new DU (74%). For 65% of the centres, the proposed classification of DU was considered useful and feasible in clinical practice. Moreover, 80% of the centres preferred the categorisation of DU in episodic, recurrent and chronic to simple distinction in recurrent/not recurrent DU. CONCLUSIONS For clinical practice, EUSTAR centres identified only three essential items for DU evaluation and considered the proposed classification and categorisation as useful and feasible. The set of items needs to be validated while further implementation of DU classification and categorisation is warranted. TRIAL REGISTRATION Observational trial on DU (OT1) is one of the five trials of the DeSScipher project (ClinicalTrials.gov; OT1 Identifier: NCT01836263 , posted on April 19, 2013).

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) require a differentiated therapeutic approach depending on the degree of organ dysfunction and disease activity. In organ dysfunction and life-threatening AAV cyclophosphamide and rituximab are recommended for the induction of remission. For remission induction with a lack of organ dysfunction and non-life-threatening AAV, methotrexate or mycophenolate mofetil are recommended. For remission maintenance therapy azathioprine or methotrexate are used. In the case of contraindications, intolerance or previous failure of azathioprine and methotrexate treatment, rituximab, leflunomide or mycophenolate mofetil may be used as alternatives. Maintenance therapy is usually continued for at least 2 years. De-escalation of therapy requires continuous clinical monitoring while the glucocorticoid medication and immunosuppressive therapy is tapered; however, every de-escalation of therapy carries a risk of relapse.

Abstract
ZusammenfassungDie systemische Sklerose gehört zu den rheumatischen Erkrankungen mit dem höchsten Einfluss auf die Prognose und Lebensqualität. Organmanifestationen wie die interstitielle Lungenfibrose, die pulmonale arterielle Hypertonie (PAH) und die Herzbeteiligung bestimmen die Mortalität, während Schmerzen, Bewegungseinschränkungen und digitale Ulzerationen häufig die Lebensqualität beeinflussen. Mangelernährung, Sarkopenie, Depression, Osteoporose, kardiovaskuläre Erkrankungen und Tumorerkrankungen treten möglicherweise bedingt durch die chronische Aktivierung des Immunsystems gehäuft auf. Es gibt derzeit erste Ansätze, Krankheitsmechanismen und die Beziehung zwischen der obliterativen Vaskulopathie und der variabel vorhandenen Fibrose zu verstehen. Die Therapie sollte frühzeitig beginnen. Eine Reihe von Substanzen beeinflusst die Raynaud-Symptomatik und die obliterative Gefäßerkrankung. Leider werden diese Therapien oftmals nicht ausreichend genutzt. Immunsuppressiva wie Cyclophosphamid, MMF oder eine autologe Stammzelltransplantation haben zu einer deutlichen Verbesserung der inflammatorischen Fibrose in klinischen Studien geführt. Neue Therapieansätze, die Krankheitsmechanismen beeinflussen und nebenwirkungsärmer sind, erscheinen erfolgversprechend und könnten künftig zu einer Zulassung führen. Derzeit wird eine Vielzahl von Studien durchgeführt. Die konsequente zielorientierte und individuelle Therapie stellt einen wichtigen Schlüssel zum Therapieerfolg dar.

Abstract
Published data suggest that coexisting interstitial lung disease (ILD) has an impact on mortality in patients with systemic sclerosis (SSc) and pulmonary arterial hypertension (PAH), but there is scarce knowledge if this is reflected by hemodynamics, exercise capacity, autoantibody profile, or pulmonary function. In this partially retrospective study, 27 SSc-PAH patients were compared to 24 SSc-PAH patients with coexisting ILD respecting to survival, pulmonary function, hemodynamics, exercise capacity, and laboratory parameters. Survival was significantly worse in SSc-PAH-ILD patients than in SSc patients with isolated PAH (1, 5, and 10-year survival rates 86, 54, and 54% versus 96, 92, and 82%, p = 0.013). Compared to isolated SSc-PAH patients, patients with SSc-PAH-ILD revealed lower forced expiratory volume after 1 s (FEV1) values at the time of PAH diagnosis as well as 1 and 2 years later (p = 0.002) without significant decrease in the PAH course in both groups. At PAH diagnosis, diffusion capacity for carbon monoxide (DLCO) values were lower in the ILD-PAH group. Coexisting ILD was not associated with lower exercise capacity, different FEV1/forced vital capacity (FVC) ratio, higher WHO functional class, or reduced hemodynamics. Higher levels of antibodies against angiotensin and endothelin receptors predict mortality in all SSc-PAH patients but could not differentiate between PAH patients with and without ILD. Our study confirmed an impact of ILD on mortality in SSc-PAH patients. Pulmonary function parameters can be used to distinguish PAH from PAH-ILD. The higher mortality rate cannot be explained by differences in hemodynamics, exercise capacity, or autoantibody levels. Mechanisms of mortality remain to be studied.

Abstract
The 2015 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension are also valid for Germany. The guidelines contain detailed information about the diagnosis of pulmonary hypertension, and furthermore provide novel recommendations for risk stratification and follow-up assessments. However, the practical implementation of the European Guidelines in Germany requires the consideration of several country-specific issues and already existing novel data. This requires a detailed commentary to the guidelines, and in some aspects an update already appears necessary. In June 2016, a Consensus Conference organized by the PH working groups of the German Society of Cardiology (DGK), the German Society of Respiratory Medicine (DGP) and the German Society of Pediatric Cardiology (DGPK) was held in Cologne, Germany. This conference aimed to solve practical and controversial issues surrounding the implementation of the European Guidelines in Germany. To this end, a number of working groups was initiated, one of which was specifically dedicated to risk stratification and follow-up assessment of patients with PAH. This manuscript summarizes the results and recommendations of this working group.

Abstract
BACKGROUND Digital ulcers (DU) affect up to 60 % of patients with systemic sclerosis (SSc) and have a considerable impact on quality of life and morbidity. It is unclear to what extent authorised medicines are used, and if therapy guidelines are implemented in everyday practice. METHOD This retrospective health care study examined current standards of treatment for therapy and prevention of SSc-associated DU in an online survey with 83 physicians. Additionally, data from 161 case studies of SSc patients with DU were analysed, and the effect of DU treatment on the course of the disease determined. RESULTS For treatment and prevention of active DU, physicians predominantly indicated topical therapies, calcium channel blockers, iloprost and endothelin receptor antagonists. According to the case studies, 90 % of episodes with acute DU were treated with bosentan and iloprost in mono- or combination therapy. Preventive treatment was only administered during 50 % of episodes without DU, even after three or more phases with active DU. For the prevention of new DU, bosentan was used in mono- or combination therapy in 57 % of episodes without DU. Bosentan therapy during prevention shortened the following acute phase by 32 %. Additionally, continuous treatment with bosentan in acute and prevention phases reduced the duration of the following acute phase and increased the time to onset of new DU by 16 %. Moreover, bosentan stabilised the number of new DU. CONCLUSION In summary, these data confirm the efficacy of bosentan in preventing new DU when used in DU-free episodes and possibly also in phases of acute DU. Therapy recommendations for the treatment of DU are currently not fully implemented. In the future, even more attention should be paid to DU therapy.
