Abstract
BACKGROUND Systemic sclerosis (SSc) is a heterogeneous disease with frequently associated interstitial lung disease (SSc-ILD). We aimed to determine the prognostic potential of phenotyping patients with SSc and SSc-ILD by inflammation and to describe disease trajectories stratified by inflammation and immunosuppressive treatment. METHODS Patients from the European Scleroderma Trials and Research (EUSTAR) group cohort were allocated to persistent inflammatory, intermediate and non-inflammatory phenotypes if C-reactive protein (CRP) levels were ≥5 mg/L at ≥80%, at 20-80% and at <20% of visits, respectively. Cox regression models were used to analyse mortality risk and mixed effect models to describe trajectories of FVC and diffusing capacity for carbon monoxide (DLCO) %-predicted stratified by inflammation and immunosuppressive treatment. RESULTS 2971 patients with SSc and 1171 patients with SSc-ILD had at least three CRP measurements available. Patients with SSc-ILD with a persistent inflammatory phenotype had a 6.7 times higher risk of mortality within 5 years compared with those with a persistent non-inflammatory phenotype (95% CI 3 to 15). In the inflammatory phenotype, FVC %-predicted was declining without (-1.11 (95% CI -2.14 to -0.08)/year), but stable with immunosuppressive treatment (-0.00 (95% CI -0.92 to 0.92)/year). In the non-inflammatory phenotype, patients with and without immunosuppressive treatment had a significant decline in FVC %-predicted, which was more pronounced in those with immunosuppressive treatment (-1.26 (95% CI -1.87 to -0.64) and -0.84 (95% CI -1.35 to -0.33)/year, respectively). CONCLUSIONS Phenotyping by persistent inflammation provides valuable prognostic information, independent of demographics, disease duration, cutaneous subtype, treatment and SSc-ILD severity. The findings from this study support early immunosuppressive treatment in patients with SSc-ILD with persistent inflammation.

Abstract
OBJECTIVE Semaphorin 3A (Sema3A) plays a regulatory role in immune responses. The aim of this study was to evaluate Sema3A levels in patients with systemic sclerosis (SSc), especially in major vascular involvements such as digital ulcer (DU), scleroderma renal crisis (SRC), pulmonary arterial hypertension (PAH), and to compare Sema3A level with SSc disease activity. METHODS In SSc patients, patients with DU, SRC, or PAH were grouped as major vascular involvements and those without as nonvascular, and Sema3A levels were compared between the groups and with a healthy control group. The Sema3A levels and acute phase reactants in SSc patients, as well as their association with the Valentini disease activity index and modified Rodnan skin score, were evaluated. RESULTS The Sema3A values (mean ± SD) were 57.60 ± 19.81 ng/mL in the control group (n = 31), 44.32 ± 5.87 ng/mL in patients with major vascular involvement SSc (n = 21), and 49.96 ± 14.00 ng/mL in the nonvascular SSc group (n = 35). When all SSc patients were examined as a single group, the mean Sema3A value was significantly lower than controls (P = .016). The SSc with major vascular involvement group had significantly lower Sema3A levels than SSc with nonmajor vascular involvement group (P = .04). No correlation was found between Sema3A, acute phase reactants, and disease activity scores. Also, no relationship was observed between Sema3A levels and diffuse (48.36 ± 11.47 ng/mL) or limited (47.43 ± 12.38 ng/mL) SSc types (P = .775). CONCLUSION Our study suggests that Sema3A may play a significant role in the pathogenesis of vasculopathy and can be used as a biomarker in SSc patients with vascular complications such as DU and PAH.

Abstract
The pentraxins represent a family of multifunctional proteins composed of long and short pentamers. The latter includes serum amyloid P component (SAP) and C-reactive protein (CRP) whereas the former includes neuronal PTX1 and PTX2 (NPTX1 and NPTX2, respectively), PTX3 and PTX4. These serve as a bridge between adaptive immunity and innate immunity and a link between inflammation and immunity. Similarities and differences between long and short pentamers are examined and their roles in autoimmune disease are discussed. Increased CRP and PTX3 could indicate the activity of rheumatoid arthritis, systemic lupus erythematosus or other autoimmune diseases. Mechanistically, CRP and PTX3 may predict target organ injury, regulate bone metabolic immunity and maintain homeostasis as well as participate in vascular endothelial remodeling. Interestingly, PTX3 is pleiotropic, being involved in inflammation and tissue repair. Given the therapeutic potential of PTX3 and CRP, targeting these factors to exert a beneficial effect is the focus of research efforts. Unfortunately, studies on NPTX1, NPTX2, PTX4 and SAP are scarce and more research is clearly needed to elaborate their potential roles in autoimmune disease.

Abstract
The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of various diseases is presented, of all cardiovascular, respiratory, hepatobiliary, gastrointestinal, pancreatic, renal, gynecological, andrological, dental, oral, otorhinolaryngological, ophthalmological, dermatological, musculoskeletal, neurological, mental, splenic, thyroid conditions, as well as infections, autoimmune-supposed conditions and neoplasms, including other possible factors that have been linked with elevated concentrations of that protein. Moreover, data on molecular diagnostics on CRP are discussed, and possible etiologies of false test results are highlighted. Additionally, this review evaluates all current pieces of evidence on CRP and systemic inflammation, and highlights future goals. Finally, a novel diagnostic algorithm to carefully assess the CRP level for a precise diagnosis of a medical condition is illustrated.

Abstract
Introduction It is hypothesized that bronchoalveolar lavage (BAL) neutrophilia, Krebs von den Lungen-6 (KL-6), and C-reactive protein (CRP) predict the severity of chronic fibrosing interstitial lung diseases (CF-ILDs). Methods This cross-sectional study enrolled 30 CF-ILD patients. Using Pearson's correlation analysis, BAL neutrophils, KL-6, and CRP were correlated with forced vital capacity (FVC), diffusing lung capacity for carbon monoxide (DLCO), six-minute walk distance (6MWD), partial pressure of oxygen (PaO2), computed tomography fibrosis score (CTFS), and pulmonary artery systolic pressure (PASP). Using the receiver operator characteristic (ROC) curve, BAL KL-6 and CRP were evaluated against FVC% and DLCO% in isolation and combination with BAL neutrophilia for predicting the severity of CF-ILDs. Results BAL neutrophilia significantly correlated only with FVC% (r = -0.38, P = 0.04) and DLCO% (r = -0.43, P = 0.03). BAL KL-6 showed a good correlation with FVC% (r = -0.44, P < 0.05) and DLCO% (r = -0.50, P = 0.02), while BAL CRP poorly correlated with all parameters (r = 0.0-0.2). Subset analysis of BAL CRP in patients with CTFS ≤ 15 showed a better association with FVC% (r = -0.28, P = 0.05) and DLCO% (r = -0.36, P = 0.04). BAL KL-6 cut-off ≥ 72.32 U/ml and BAL CRP ≥ 14.55 mg/L predicted severe disease with area under the curve (AUC) values of 0.77 and 0.71, respectively. The combination of BAL neutrophilia, KL-6, and CRP predicted severity with an AUC value of 0.89. Conclusion The combination of BAL neutrophilia, KL-6, and CRP facilitates the severity stratification of CF-ILDs complementing existing severity parameters.

Abstract
The soluble urokinase plasminogen activator receptor (suPAR) is the bioactive form of uPAR, a membrane-bound glycoprotein, and it is primarily expressed on the surface of immunologically active cells. Mirroring local inflammation and immune activation, suPAR has gained interest as a potential prognostic biomarker in several inflammatory diseases. Indeed, in many diseases, including cancer, diabetes, cardiovascular diseases, kidney diseases, and inflammatory disorders, higher suPAR concentrations have been associated with disease severity, disease relapse, and mortality. Our review describes and discusses the supporting literature concerning the promising role of suPAR as a biomarker in different autoimmune rheumatic and non-rheumatic diseases.

Inflammatory arthritis in systemic sclerosis is associated with elevated C-reactive protein and requires musculoskeletal ultrasound for reliable detection. Front Med (Lausanne) 2023; 9:933809.

Abstract
Objectives About 25% of patients with systemic sclerosis (SSc) have elevated C-reactive protein (CRP) levels. Specific causes of CRP elevation are unknown so far. We aimed to investigate whether inflammatory arthritis is associated with CRP elevation. Furthermore, we evaluated the sensitivity and specificity of clinical examination compared to musculoskeletal ultrasound (MSUS) for detection of arthritis. Methods Sixty-five patients with SSc (51 females) were enrolled and allocated into a CRP-positive (CRP+, n = 20; CRP elevated for at least two years prior to enrollment) and a CRP-negative (CRP-; n = 45) cohort. All patients were examined clinically (modified Rodnan Skin Score, mRSS; swollen/tender joint count 66/68), received a comprehensive MSUS of their hands and feet, as well as laboratory testing (antibody status; CRP). Statistical analyses were performed using non-parametrical tests without adjustments. Results Patient with a disease duration <3 years had higher CRP levels (p = 0.042). Anti-centromere antibodies dominated in CRP- patients (p = 0.013), and anti-Scl70 antibodies in CRP + patients (p = 0.041). Joint effusion and B-mode synovitis prevailed in male (p < 0.00001; p < 0.0001) and CRP + (p = 0.001; p < 0.00001) patients. Power Doppler (PD)-synovitis predominated in patients with diffuse SSc (p = 0.0052). Joint effusion and B-/PD-synovitis were mostly confined to wrists, MTPs and talo-navicular joints. Compared to MSUS, sensitivity of clinical examination was as low as 14.6%; specificity was 87.7%. Sensitivity was reduced by the presence of soft tissue edema or a mRSS > 10. Conclusion Arthritis is more frequent in CRP + compared to CRP- SSc patients. Compared to MSUS sensitivity of clinical examination is low for the detection of arthritis; this is likely due to skin fibrosis and soft tissue edema. Therefore, regular monitoring via MSUS should be considered as routine assessment in SSc patients.

Abstract
Background. Systemic sclerosis (SSc) is an autoimmune inflammatory disease of connective tissue with a polysyndromic clinical picture. One of the factors that significantly affect the quality of life of such patients is the involvement of the musculoskeletal system. A small number of studies were aimed at studying osteoporosis and body composition in patients with SSc, however, the clinical heterogeneity of the disease, a small number of patients included in the studies do not allow to draw unambiguous conclusions about the frequency of various phenotypes of body composition, their relationship and factors affecting their occurrence.Aim. To study the body composition and to establish the frequency of isolated and combined pathological phenotypes in women with SSс and to determine the factors associated with the muscle mass.Materials and methods. 85 postmenopausal women (46 with SSc, 39 without rheumatic pathology) were included. Questionnaires, anthropometric measurements, assessment of nutritional status by MNA, dual-energy X-ray absorptiometry of the whole body, lumbar spine, femoral neck and total hip were carried out. Correlation and univariate linear regression analyses were performed to identify factors related to appendicular muscle mass.Results. Normal body composition was found in 13.0% of patients with SSс and 25.6% — in the control, isolated and combined pathological phenotypes were detected in 34.8% and 52.2% women with SSс and in 61.5% and 12.8% in the group without rheumatic diseases, respectively. Combined pathological phenotypes, phenotypes with the presence of sarcopenia and/or osteoporosis were significantly more often in SSc patients (p< 0.001), but the frequency of obesity did not differ (69.6% and 64.1%, respectively). Negative correlations were revealed between the value of appendicular muscle mass and the presence of osteolysis of the nail phalanges (Rs=-0.23), the cumulative dose of glucocorticoids (GC) (Rs=-0.43) and direct — with the value of the femoral neck BMD (Rs=0.47), nutritional status by MNA (Rs=0.51), BMI (Rs=0.70), the circumference of the shoulder of the non-dominant arm (Rs=0.68), waist (Rs=0.66), hips (Rs=0.72) and lower leg of the non-dominant leg (Rs=0.81), p< 0.05. Univariate linear analysis confirmed the presence of positive associations between the appendicular muscle mass and proximal hip BMD, BMI, shoulder circumferences, waist, hips and lower leg (p< 0.001), and negative associations with the Rodnan skin score (p=0.012) and the cumulative dose of GC (p=0.001).Conclusion. 87% of patients with SSc had pathological phenotypes of body composition, among them combined phenotypes were significantly more common than in people without rheumatic diseases. BMD in the proximal hip, BMI, circumference of the shoulder, waist, hips and lower leg were positively, and the Rodnan skin score and cumulative dose of GC were negatively associated with the appendicular muscle mass.

Abstract
Abstract
Purpose of Review
Interstitial lung disease (ILD) is the leading cause of mortality in systemic sclerosis, a rare autoimmune disease characterised by fibrosis and vasculopathy. The variety of phenotypes in SSc-ILD have inspired multiple studies aimed at the identification of biomarkers which can provide disease-specific information but due to the complex pathogenesis of SSc-ILD, it has been challenging to validate such markers. We provide a comprehensive update on those most studied along with emerging biomarkers.
Recent Findings
We review the up-to-date findings with regard to the use of well-studied molecular biomarkers in SSc-ILD along with novel biomarkers offering promise as prognostic markers such as IGFBP-2 and IGFBP-7, the adipokine CTRP9, endothelial progenitor cells, and cellular markers such as CD21lo/neg B cells. Expression profiling data is being used in SSc patients to determine genetic and epigenetic clusters which shed further light on mechanisms involved in the pathogenesis of SSc-ILD and are likely to uncover novel biomarkers.
Summary
With the exception of autoantibodies, there are no routinely measured biomarkers in SSc-ILD and reliable validation of the many potential biomarkers is lacking. Identifying biomarkers which can offer diagnostic and prognostic certainty may help patients to receive preventative treatment as part of a personalised medicine approach.

Abstract
Systemic sclerosis (SSc) is a complex autoimmune connective tissue disease with distinct pathological hallmarks (ie, inflammation, vasculopathy, fibrosis) that may predominate at different stages in the disease course with varying severity. Initial efforts to classify patients with SSc identified a subset of patients with very early SSc. These patients possessed signs of SSc (eg, Raynaud phenomenon, SSc specific autoantibodies and/or nailfold capillary abnormalities) without fulfilling complete SSc classification criteria. Recognizing the inherent value in early diagnosis and intervention in SSc, researchers have endeavored to identify risk factors for progression from very early SSc to definite SSc. The present review summarizes the clinical phenotype of patients with very early and early SSc. Through a scoping review of recent literature, this review also describes risk factors for progression to definite SSc with a focus on the specific clinical features that arise early in the SSc disease course (eg, diffuse cutaneous sclerosis, interstitial lung disease, esophageal dysfunction, renal crisis, cardiac involvement). In addition to clinical risk factors, this review provides evidence for how biological data (ie, serological, genomic, proteomic profiles, skin bioengineering methods) can be integrated into risk assessment models in the future. Furthering our understanding of biological features of very early SSc will undoubtedly provide novel insights into SSc pathogenesis and may illuminate new therapeutic targets to prevent progression of SSc.

Association between Routine Laboratory Parameters and the Severity and Progression of Systemic Sclerosis. J Clin Med 2022; 11:jcm11175087. [PMID: 36079017 PMCID: PMC9457158 DOI: 10.3390/jcm11175087] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 08/24/2022] [Accepted: 08/26/2022] [Indexed: 11/16/2022] Open
Abstract
(1) Background: Systemic sclerosis (SSc) is a heterogeneous connective tissue disease with a high mortality and morbidity rate. Identification of biomarkers that can predict the evolution of SSc is a key factor in the management of patients. The aim of this study was to assess the association of routine laboratory parameters, widely used in practice and easily available, with the severity and progression of SSc. (2) Methods: In this retrospective monocentric cohort study, 372 SSc patients were included. We gathered clinical and laboratory data including routine laboratory parameters: C-reactive-protein (CRP), erythrocyte sedimentation rate (ESR), complete blood count, serum sodium and potassium levels, creatinin, urea, ferritin, albumin, uric acid, N-terminal pro-brain natriuretic peptide (NTproBNP), serum protein electrophoresis, and liver enzymes. Associations between these routine laboratory parameters and clinical presentation and outcome were assessed. (3) Results: Median (interquartile range) age was 59.0 (50.0; 68.0) years. White blood cell, monocyte, and neutrophil absolute counts were significantly higher in patients with diffuse cutaneous SSc and with interstitial lung disease (ILD) (p < 0.001). CRP was significantly higher in patients with ILD (p < 0.001). Hemoglobin and ferritin were significantly lower in patients with pulmonary hypertension (PH) including pulmonary arterial hypertension and ILD associated PH (p = 0.016 and 0.046, respectively). Uric acid and NT pro BNP were significantly higher in patients with PH (<0.001). Monocyte count was associated with ILD progression over time. (4) Conclusions: Overall, our study highlights the association of routine laboratory parameters used in current practice with the severity and progression of SSc.

Abstract
Objective The purpose of this study was to explore the clinical significance of serum ferritin (SF) in patients with systemic sclerosis (SSc). Methods The levels of SF were measured in 115 patients with SSc and 117 healthy controls (HCs). Clinical characteristics and laboratory indexes between the high ferritin SSc group and the normal ferritin SSc group were analyzed. Results The level of SF in SSc patients was significantly higher than that in HCs (319.78 [179, 554.33] ng/ml vs. 99 [49.03, 164.29] ng/ml, p < 0.01). Compared with the normal ferritin SSc group, the high ferritin SSc group was more likely to develop skin diffuse cutaneous SSc, fingertip arthralgia, and cardiac involvement. In addition, the levels of glutamine transaminase (GGT), alanine aminotransferase (ALT), creatine kinase (CK), creatine kinase isoenzyme‐MB (CK‐MB), lactate dehydrogenase (LD), immunoglobulin G (IgG), immunoglobulin A (IgA), C‐reactive protein (CRP), erythrocyte sedimentation rate (ESR), and the positive rate of anti‐Scl70 antibody in the high ferritin SSc group were significantly higher (each p < 0.05). SF was positively correlated with GGT, ALT, CK, CK‐MB, LD, IgA, CRP, and ESR (each p < 0.05). Multiple linear regression analysis showed that cardiac involvement, ALT, and ESR were independent influencing factors of SF in SSc. Conclusion Our study shows that the level of SF in patients with SSc is increased, and the elevated SF is related to abnormal liver function, myocardial involvement, inflammatory status, and production of autoantibodies in SSc. Cardiac involvement, ALT, and ESR are independent factors affecting SF in SSc.

Abstract
PURPOSE OF REVIEW The purpose of our review was to evaluate current standards in clinical practice in determining overall cardiac risk in female patients with chronic rheumatologic diseases. We hoped to not only summarize known cardiac manifestations of various chronic rheumatologic diseases but also determine the effectiveness of new risk scores in determining cardiac risk in this patient population. RECENT FINDINGS Chronic rheumatologic diseases have been associated with various cardiac manifestations for some time, with initial studies involving risk of coronary artery disease (CAD) in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). However, recent studies have shown numerous other cardiac manifestations associated with these and other chronic rheumatologic diseases. Risk scores have been used for several decades to help determine overall cardiac risk in the general population, but these risk scores have notoriously underestimated the risk of cardiac disease in woman and in patients with chronic rheumatologic diseases. These diseases, often with a female predominance, can impact long-term mortality and have devastating consequences if not monitored and treated appropriately. Thus, new risk scores have been developed over the last several years to help improve detection and awareness of cardiac disease in these patients. Novel modified risk scores have found some success at improving the detection of cardiac disease in patients with chronic rheumatologic diseases. Further studies looking at these risk scores need to determine the accuracy of these scores and where they fall short. With the advent of advanced imaging technologies, future risk scores may involve certain imaging-based markers to help guide accurate risk determination.

Life (Basel) 2022; 12:life12050646. [PMID: 35629314 PMCID: PMC9146715 DOI: 10.3390/life12050646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 04/25/2022] [Accepted: 04/25/2022] [Indexed: 11/16/2022] Open
Abstract
Objectives: To determine whether C-X-C chemokine ligand 1 (CXCL1), which is a potent neutrophil chemoattractant and activator that plays important role in inflammation, is elevated in patients with systemic sclerosis (SSc) and whether it is associated with the clinical features and disease activity of patients with SSc. In addition, to determine whether the changes in serum CXCL1 levels before and after treatment correlate with changes in disease activity in SSc patients who received an anti-CD20 monoclonal antibody drug. Patients and method: We examined patient serum collected in the DesiReS trial, which was a double-blind, parallel-group, randomized, placebo-controlled, multicenter, phase II clinical trial. In the trial, patients were randomly allocated to the drug or placebo group and received 375 mg/m2 of an anti-CD20 antibody, rituximab, or placebo once a week for four weeks. We obtained serum samples from 47 patients administered at our hospital, including 3 males and 44 females, the median age of 48 years, range 27−71 years, with 42 diffuse cutaneous SSc and 5 with limited cutaneous SSc. Serum CXCL1 levels were measured using multiplex immunoassay in patient serum before and 24 weeks after administration and also in serum from 33 healthy controls. Results: Serum CXCL1 levels were significantly higher in SSc patients (mean 25.70 ng/mL; 95% confidence interval (CI) 18.35−33.05 ng/mL) than in the healthy controls (15.61 ng/mL; 95% CI 9.73−21.51 ng/mL). In addition, SSc patients with elevated CXCL1 levels had a significantly higher percentage of area occupied with interstitial shadows (p < 0.05), increased serum levels of surfactant protein (SP)-A (p < 0.05), SP-D (p < 0.05), Krebs von den Lungen-6 (p < 0.01), and C-reactive protein (p < 0.05) compared to those with normal levels. Furthermore, defining Δ as the value after rituximab administration minus the value before rituximab administration, baseline serum CXCL1 levels correlated with Δ percent predicted diffusing capacity for carbon monoxide (p < 0.01). In addition, ΔCXCL1 correlated with ΔSP-A (p < 0.05). Similarly, serum CXCL1 levels after rituximab administration correlated with percent predicted forced vital capacity (p < 0.05) and serum SP-D levels (p < 0.05) after rituximab. Conclusions: Our results suggest that serum CXCL1 is associated with the disease activity of SSc-ILD, and high serum CXCL1 levels are one of the predictors of improvement in SSc-ILD with rituximab.

Abstract
Objective The aim of this study was to determine the independent value of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein to predict onset of cardiopulmonary disease in a large, multi-center systemic sclerosis cohort followed prospectively. Methods Subjects from the Canadian Scleroderma Research Group registry with data on N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were identified. Outcomes of interest were death, systolic dysfunction (left ventricular ejection fraction < 50% or medications for heart failure), pulmonary arterial hypertension by right heart catheterization, pulmonary hypertension by cardiac echocardiography (systolic pulmonary artery pressures ⩾ 45 mmHg), arrhythmias (pacemaker/implantable cardiac defibrillator or anti-arrhythmic medications), and interstitial lung disease. Multivariate Cox proportional hazard models were generated for each outcome. Results A total of 675 subjects were included with a mean follow-up of 3.0 ± 1.8 years. Subjects were predominantly women (88.4%) with mean age of 58.2 ± 11.3 years and mean disease duration of 13.7 ± 9.1 years. One hundred and one (101, 15%) subjects died during follow-up, 37 (6.4 %) developed systolic dysfunction, 18 (2.9%) arrhythmias, 34 (5.1%) pulmonary arterial hypertension, 43 (7.3%) pulmonary hypertension, and 48 (12.3%) interstitial lung disease. In multivariate analyses, elevated levels of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were associated with increased risk of death, while elevated levels of N-terminal pro b-type natriuretic peptide and C-reactive protein were associated with increased risk of developing pulmonary hypertension. Conclusion In systemic sclerosis, N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein have independent predictive value for death and pulmonary hypertension. A larger study would be required to determine the predictive value of these biomarkers for less common systemic sclerosis outcomes.

Abstract
Introduction Systemic sclerosis (SScl) is an autoimmune disease whose prevalence is rarely reported in Africa. Autoantibodies are the biomarkers of the condition, precede overt disease and determine disease phenotypes. SSc specific autoantibodies also vary between racial groupings. Objective: To investigate the clinical and laboratory characteristics of Zimbabwean patients who were reactive SSc specific autoantibodies. Materials and Method 240 patients, 173 of them female with SSc specific autoantibodies were included. Autoantibodies were detected by indirect immunofluorescence microscopy and immunoblotting using a panel of 13 SScl (Euroimmun Ag., Germany). Demographic, clinical and laboratory parameters relevant to the monitoring of SScl were captured. These included pulmonary function tests, hematology, clinical chemistry, serology and thyroid function tests. Allergy skin prick tests (SPT) to inhalant and food allergen sources were conducted when indicated. Results All the 240 patients (median age was 36 years) expressed SSc specific autoantibodies. 86% were Black, 11% White and 3% Asian and a fifth (20%) were younger than 16 years. Eleven (4.6%) fulfilled the ACR/EULAR classification of SSc. Clinically they had limited cutaneous (n=6), diffuse cutaneous (n=3) and SScl/inflammatory myopathy overlap (n=2). The most frequently detected antibodies anti-RNA polymerase III (RNAP) 55%, anti-Th/To (28%) anti-RNAP 11 (22%), anti-CENPB (18%) and anti-Scl-70/ATA (13%). Racial variations in the expression of these antibodies were apparent between Black, White and Asian patients. The majority (95%), who did not fulfil the ARA/EULAR criteria were symptomatic. Raynaud’s Phenomenon was documented in 24%. Respiratory symptoms included coughing, dyspnea and wheezing. There was a restrictive ventilatory defect with increased FEV1/FVC ratio. Pruritus, urticaria and skin depigmentation were the main cutaneous features while constipation, bloating, Gastroesophageal reflux disease (GERD) and abdominal pain dominated GI symptoms. Mean blood pressure readings while normal varied with biomarkers. Haematology and biochemistry parameters were within normal reference ranges. Conclusion The expression of SSc specific autoantibodies is common and associated with known SSc symptoms. The types and frequency of autoantibodies varied with racial groupings. A fifth of the patients were children below the age of 16 years.

Abstract
Objectives
This study aims to investigate the prevalence of persistent eosinophilia and associated organ complications in Thai patients with systemic sclerosis (SSc). Patients and methods
This post-hoc study included 107 adult patients (23 males, 84 females; mean age: 50.4±11.6 years; range, 18 to 79 years) diagnosed with SSc between November 2013 and June 2017. Eosinophilia was defined as an absolute eosinophil count of >500/μL or a percentage count of >7%. Eosinophil levels collected at every visit over one year were categorized as persistently high (PH), persistently low (PL), high-to-low (HL), low-to-high (LH), or variable levels (VL). The study compared variables between PH and non-PH (PL+HL+LH+VL) groups. The patients with baseline eosinophilia were also identified and compared with the non-eosinophilia group. Results
The median disease duration was 3.2 years. Of the patients, 79.4% had diffuse cutaneous SSc and 76.7% had anti-Scl-70 positivity. A total of 11.2%, 66.4%, 1.9%, 8.4%, and 12.1% of the patients were categorized into the PH, PL, HL, LH, and VL groups, respectively. Compared to non-PH groups, the PH group had a higher prevalence of anti-centromere antibody (ACA), higher baseline percent predicted total lung capacity, and lower baseline C-reactive protein and creatine phosphokinase (p<0.05 for all). The ACA positivity (odds ratio [OR]: 18.5; 95% confidence interval [CI]: 1.64-208.46) was associated with PH. The patients with baseline eosinophilia (17.8%) had a higher prevalence of non-specific interstitial pneumonia with periodic eosinophilia at the time of diagnosis (100% vs. 6.5%, p<0.0001; OR: 4.667; 95% CI: 1.712-12.724). Conclusion
The PH was seldom (11%) in patients with SSc compared to periodic eosinophilia, which was more prevalent (18%). It may be related to ACA positivity and better pulmonary outcomes, whereas periodic eosinophilia may involve interstitial lung disease.

Abstract
OBJECTIVE To investigate the epidemiology and characteristics of systemic sclerosis (SSc) overlap syndrome (SSc-OS). METHODS This study included patients enrolled in the Siriraj Systemic Sclerosis Cohort registry during November 2013 to September 2019. SSc-OS was defined as SSc patients who also met criteria for rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), dermatomyositis (DM), polymyositis (PM), Sjogren, and/or antiphospholipid antibody syndrome. Baseline and 1-year characteristics were compared between SSc and SSc-OS. RESULTS 185 patients (age 50.3 ± 11.4 years, 85.4% female, disease duration 2.7 years, 75.1% diffuse cutaneous subset, 75.6% anti-Scl-70 positivity) were included. The incidence and prevalence rate of SSc-OS was 3.2/100 patient-years and 17.8%. Regarding SSc-OS, 12.4%, 2.2%, 1.1%, 1.6%, and 0.5% of patients were classified as SSc-RA, SSc-SLE, SSc-PM, SSc-RA-SLE, and SSc-SLE-PM. SSc-OS had a higher prevalence of limited cutaneous subset (lcSSc), usual interstitial pneumonia, finger contractures, ESR >20 mm/hr., globulin >3.5 g/dL, rheumatoid factor, anti-citrullinated peptide antibody, and antiphospholipid antibodies. LcSSc subset (OR: 11.3, 95%CI: 2.0-62.6) and globulin >3.5 g/dL (OR: 6.2, 95%CI: 1.6-23.6) were associated with SSc-OS. CONCLUSION SSc-OS is associated with the lcSSc subset. RA is the most common overlap syndrome. LcSSc patients with globulin >3.5 g/dL are associated with SSc-OS.

Abstract
OBJECTIVE Response to immunosuppression is highly variable in systemic sclerosis (SSc)-related interstitial lung disease (ILD). This study was undertaken to determine whether a composite serum interferon (IFN)-inducible protein score exhibits predictive significance for the response to immunosuppression in SSc-ILD. METHODS Serum samples collected in the Scleroderma Lung Study II, a randomized controlled trial of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC), were examined. Results were validated in an independent observational cohort receiving active treatment. A composite score of 6 IFN-inducible proteins IFNγ-inducible 10-kd protein, monokine induced by IFNγ, monocyte chemotactic protein 2, β2 -microglobulin, tumor necrosis factor receptor type II, and macrophage inflammatory protein 3β) was calculated, and its predictive significance for longitudinal forced vital capacity percent predicted measurements was evaluated. RESULTS Higher baseline IFN-inducible protein score predicted better response over 3 to 12 months in the MMF arm (point estimate = 0.41, P = 0.001) and CYC arm (point estimate = 0.91, P = 0.009). In contrast, higher baseline C-reactive protein (CRP) levels were predictive of a worse ILD course in both treatment arms. The predictive significance of the IFN-inducible protein score and CRP levels remained after adjustment for baseline demographic and clinical predictors. During the second year of treatment, in which patients in the CYC arm were switched to placebo, a higher IFN-inducible protein score at 12 months showed a trend toward predicting a worse ILD course (point estimate = -0.61, P = 0.068), while it remained predictive of better response to active immunosuppression in the MMF arm (point estimate = 0.28, P = 0.029). The predictive significance of baseline IFN-inducible protein score was replicated in the independent cohort (rs = 0.43, P = 0.028). CONCLUSION A higher IFN-inducible protein score in SSc-ILD is predictive of better response to immunosuppression and could potentially be used to identify patients who may derive the most benefit from MMF or CYC.

Abstract
OBJECTIVE We assessed the association of suPAR (soluble urokinase plasminogen activator receptor) plasma levels with fibrotic and vascular manifestations in patients with systemic sclerosis (SSc). METHODS suPAR plasma levels were measured in 121 consecutive patients with SSc and correlated to pulmonary and vascular features of SSc, including interstitial lung disease as characterized by percentage of predicted CO diffusing capacity (DLco) and forced vital capacity (FVC), pulmonary fibrosis by computed tomography, and pulmonary arterial hypertension, telangiectasias, and digital ulcers. RESULTS Overall, 121 SSc patients (84% females; mean age, 57 ± 12 [range: 22-79] years) were enrolled; 35% had diffuse cutaneous SSc. suPAR plasma levels ranged from 1.3-10.2 [median: 2.9 (p25-p75: 2.3-3.9)] ng/mL. Log(suPAR) levels correlated with DLco (r = -0.41, p <0.0001) and FVC (r = -0.26, p = 0.004), also when adjusted for age, sex, and pulmonary hypertension. A suPAR cut-off level of >2.5 ng/mL showed a sensitivity of 91% for identifying patients with either DLco <50% or FVC < 60% of the predicted values. Similarly, 19 (90%) had a suPAR >2.5 ng/mL among those diagnosed with pulmonary fibrosis vs. 59 (60%) among those who did not (p = 0.008). suPAR values were not associated with vascular manifestations. CONCLUSION suPAR levels strongly correlated with pulmonary involvement in SSc. Future studies should test if suPAR estimation can be used for surveillance of severe pulmonary involvement in SSc.

Abstract
OBJECTIVES Calcinosis cutis is often found with systemic sclerosis (SSc). However the calcinosis cutis and its clinical association among SSc patients is limited. Our aims were to assess the prevalence of calcinosis cutis and its association with clinical features of SSc patients at early onset of the disease. METHODS A cross-sectional study on clinical characteristics and hand radiographs of 120 newly diagnosed SSc patients with the onset less than four years were evaluated. Calcinosis cutis was described based on the anatomical regions, density (level 1-3) and shapes (net, plate, stone, and amorphous). RESULTS Among all SSc patients enrolled, 62.5% were females and 56.1% were diffuse cutaneous SSc. The mean disease duration was 2.0 ± 1.3 years. Calcinosis cutis was detected in 60 patients with the prevalence of 50% (95%confidence interval (CI), 0.41-0.59), of which 53.3% occurred at distal phalanx, 96.7% had stone shape and 48.3% were high density. Univariate analysis revealed that calcinosis cutis was associated with age (p = .02) and high-density calcinosis cutis was associated with Raynaud's phenomenon (p = .02), ischemic ulcer (p = .04), and telangiectasis (p = .02). Logistic regression analysis revealed that calcinosis cutis at distal phalanx was negatively associated with edema at the onset (odds ratio, 0.09). CONCLUSION Occult calcinosis cutis can be detected by hand radiograph in one half of SSc patients at early onset of the disease. Elderly patient has a risk for calcinosis cutis development and Raynaud's phenomenon was associated with high density calcinosis cutis. Calcinosis cutis, particularly at distal phalanx was less likely to be detected in an edematous phase of disease.

Abstract
Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by dysregulation of the immune system, vascular damage, and fibrosis of the skin and internal organs. Patients with SSc show a heterogeneous phenotype and a range of clinical courses. Therefore, biomarkers that are helpful for precise diagnosis, prediction of clinical course, and evaluation of the therapeutic responsiveness of disease are required in clinical practice. SSc-specific autoantibodies are currently used for diagnosis and prediction of clinical features, as other biomarkers have not yet been fully vetted. Krebs von den Lungen-6 (KL-6), surfactant protein-D (SP-D), and CCL18 have been considered as serum biomarkers of SSc-related interstitial lung disease. Moreover, levels of circulating brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) can provide diagnostic information and indicate the severity of pulmonary arterial hypertension. Assessment of several serum/plasma cytokines, chemokines, growth factors, adhesion molecules, and other molecules may also reflect the activity or progression of fibrosis and vascular involvement in affected organs. Recently, microRNAs have also been implicated as possible circulating indicators of SSc. In this review, we focus on several potential SSc biomarkers and discuss their clinical utility.

Abstract
OBJECTIVE To characterize cardiovascular (CV) risk factors and outcomes among incident cases of systemic sclerosis (SSc) in a population-based cohort. METHODS Medical records of patients with SSc diagnosed in Olmsted County, Minnesota, between January 1, 1980, and December 31, 2016, were reviewed to identify 78 incident SSc cases. The comparators were 156 sex- and age-matched individuals from the same population. Data for SSc characteristics, traditional CV risk factors, and CV events were collected. Cumulative incidence was adjusted for the competing risk for death. RESULTS During a median follow-up of 9.8 (SSc) and 9.2 years (non-SSc), 21 patients with SSc and 17 patients without SSc developed CV events, corresponding to 10-year cumulative incidence of 24.4% and 15.2%, respectively. The risk for incident CV disease was increased by 2-fold (hazard ratio, 2.38; 95% CI, 1.28-4.43) in patients with SSc vs comparators, predominately due to coronary artery disease (hazard ratio, 2.35; 95% CI, 1.17-4.71). Mean body mass index and prevalence of diabetes mellitus were lower in SSc vs non-SSc. There was no significant difference in smoking, hypertension, or hyperlipidemia. Observed CV events were increased compared with CV events predicted by the Framingham Risk Score and American College of Cardiology/American Heart Association score with standardized incident ratios of 4.16 (95% CI, 2.16-7.99) and 5.69 (95% CI, 2.71-11.94), respectively. CONCLUSION Patients with SSc are at >2-fold increased risk for experiencing a CV event compared with persons without SSc. Framingham Risk Score and American College of Cardiology/American Heart Association score dramatically underestimate CV risk in SSc.

Abstract
PURPOSE OF REVIEW To discuss recent advances in identification of biomarkers in systemic sclerosis for disease severity, prognosis, and treatment response. RECENT FINDINGS Recent reports describe novel circulating markers of disease severity, autoantibody associations with specific manifestations including cancer, and skin gene expression-based predictors of modified Rodnan skin score progression and treatment response. Moreover, there is converging evidence that C-reactive protein and pneumoproteins such as Krebs von den Lungen-6 and chemokine ligand 18 could serve as prognostic biomarkers in systemic sclerosis-associated interstitial lung disease. SUMMARY Several novel biomarkers show promise in improving the assessment of systemic sclerosis (SSc) disease severity, prognosis, and treatment response. Their potential utility in prospective selection of patients for clinical trials and in individual patient management require additional research.

Abstract
BACKGROUND The pathological basis of coronary artery disease (CAD) is atherosclerosis which is associated with inflammation and dyslipidemia. However, the involvement of hypersensitive C-reactive protein (hs-CRP) in lipid metabolism and how it affects the pathogenesis of CAD is uncertain. OBJECTIVE To explore whether the relationship between dyslipidemia and CAD is partly mediated by hs-CRP levels. METHODS Three hundred fifteen pairs of randomly sexand age-matched CAD and non-CAD subjects collected from Zhongda Hospital Affiliated to Southeast University were involved in the final analysis. We gathered information about each subjects clinical history as well as their results of detected hs-CRP and lipid levels. Linear regression analysis was used to determine the association between dyslipidemia and hs-CRP levels in which univariate and multivariate logistic regression analyzes were performed to determine the relationship between hs-CRP levels and CAD as well as dyslipidemia and CAD. Mediation analysis was used to evaluate whether hs-CRP levels act as a mediator of the relationship between dyslipidemia and CAD. RESULTS Dyslipidemia and hs-CRP levels were significantly associated with an increased risk of CAD, with β = 0.594 (P = 0.001) and β = 0.016 (P = 0.024), respectively, and there was a correlation between dyslipidemia and hs-CRP levels (β = 3.273, P = 0.004). Mediation analysis results revealed that the correlation between dyslipidemia and CAD was 8.27% mediated by hs-CRP levels with a direct effect of 0.621 and an indirect effect of 0.056. CONCLUSION Hs-CRP levels played a partial mediation role in the association between dyslipidemia and CAD.

Abstract
OBJECTIVES To evaluate and compare the clinical implications of common inflammatory markers in systemic rheumatic diseases (SRDs). METHOD We investigated the profiles of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell (WBC) count in treatment-naïve patients with SRDs, osteoarthritis and pneumonia diagnosed at Seoul National University Hospital during 2004-2016. SRDs included rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM) and adult-onset Still's disease (AOSD). Associations between inflammatory markers were evaluated using Pearson's correlation and regression analysis. ROC curve analysis was performed to examine the predictive value of inflammatory markers for SRD diagnosis. RESULTS We identified a total of 1191 patients. Leukocytosis was present in < 20% SRD patients. There was marked variability in ESR and CRP levels among different SRDs. The highest mean CRP levels (mean ± SD, mg/dL) were observed in AOSD (11.3 ± 7.9), followed by RA (2.0 ± 3.3), IIM (1.8 ± 3.5), SLE (1.5 ± 3.1), SSc (0.6 ± 1.3) and AS (0.08 ± 0.1). Mean ESR (mm/h) was also highest in AOSD (71.2 ± 31.0), followed by SLE (47.3 ± 34.2), RA (45.5 ± 30.6), IIM (40.8 ± 24.8) and SSc (27.8 ± 26.0). All SRDs showed significant positive correlations between ESR and CRP: greatest in RA (r = 0.53, p < 0.001) and weakest in SLE (r = 0.20, p = 0.03). WBC correlated weakly with CRP but not with ESR in most SRDs. While the AUC for WBC count was less than that of ESR or CRP, the AUC for ESR and CRP were similar in SRD. The optimal cuff-off values for inflammatory markers predicting SRD were within or slightly above the normal limit. CONCLUSIONS ESR, CRP and WBC are not always elevated in treatment-naïve patients with SRD. Individual SRDs have a unique profile of inflammatory markers. However, routine inflammatory markers should still be interpreted with caution when diagnosing and assessing disease activity in those with SRD. Key Points •Leukocytosis and elevation of ESR and CRP are not always present in all systemic rheumatic diseases. •Inflammatory markers are often dissociated and they are not specific for disease diagnosis. •Better biomarkers, which measure disease-specific local and systemic inflammation, are needed.

Abstract
SSc is a rare disease of unknown origin associated with multiple organ involvement. One of the major complications that drives the mortality of SSc patients is interstitial lung disease. The course of SSc-interstitial lung disease progression has a wide spectrum. Since the treatment is based on aggressive immunosuppression it should not be given to stable or non-progressing disease. The correct identification of disease with high risk of progression remains a challenge for early therapeutic intervention, and biomarkers remain urgently needed. In fact, eight categories of biomarkers have been identified and classified according to the different biological pathways involved. The purpose of this article is to describe the main biomarkers thought to be of interest with clinical value in the diagnosis and prognosis of SSc-interstitial lung disease.

Abstract
Interstitial lung disease is a frequent organ manifestation in systemic sclerosis and is associated with high mortality. It is crucial to diagnose interstitial lung disease in systemic sclerosis and to assess severity and identify patients prone to progression at an early stage to ultimately decrease organ damage and improve outcome. Circulating anti-topoisomerase-I autoantibodies have long been associated with the presence and development of systemic sclerosis - interstitial lung disease, evidence on their potential to further predict the clinical course of systemic sclerosis is however conflicting. C-reactive protein is a marker of infection and systemic inflammation with widespread clinical application and is elevated in systemic sclerosis with a tendency towards higher abundancy in patients with early disease. The role of other circulating biomarkers is promising but hampered by the lack of standardized criteria and guidelines for sample/data collection, analyses, reporting and validation and has not reached prime time for clinical application. However, epithelial markers including Krebs von den Lungen-6 and surfactant protein D and several cytokines and chemokines including CCL2 and CCL18 for severity assessment of systemic sclerosis - interstitial lung disease patients at the time of interstitial lung disease diagnosis and to predict interstitial lung disease progression have been reported and seem to be promising candidate biomarkers in the future.

Abstract
Background/purpose Elevated levels of C-reactive protein (CRP) in systemic sclerosis (SSc) have been linked to early inflammatory stages of the disease. This study has been designed to investigate CRP levels longitudinally in a cohort of SSc patients and to correlate these findings with comorbidities and disease characteristics. Methods In this retrospective study, patients with SSc treated at the outpatient clinic of the Department of Rheumatology and Clinical Immunology, University Medical Center Freiburg, were analyzed. Only patients with at least three consecutive visits and at least 1 year follow-up were included in this study. CRP serum levels were measured at every visit and categorized as positive if CRP concentrations were ≥ 5 mg/l. Subjects with elevated CRP levels at more than 80% of visits were defined as inflammatory SSc. The longitudinal CRP profiles were correlated with disease characteristics and comorbidities. Results A total of 1815 consecutive visits of 131 SSc patients were analyzed. Over the observed time span (7.6 (1.0–19.5) years), 18.3% (n = 24) of patients had continuously elevated CRP levels (inflammatory SSc), whereas in 29% (n = 38), CRP levels were always in the normal range. There was no association between disease duration and CRP levels at first visit. Inflammatory SSc was associated with male gender (p = 0.022), anti-Scl-70 antibodies (p = 0.009), diffuse cutaneous SSc (p = 0.036), pulmonary fibrosis (p < 0.001), rheumatoid arthritis (p = 0.007), and cardiac arrhythmia (p = 0.048). Moreover, patients with inflammatory SSc revealed higher modified Rodnan skin scores (p < 0.001); lower forced vital capacity (FVC) (p < 0.001), total lung capacity (p = 0.001), and diffusing capacity (p = 0.008); and faster decline of FVC per year (p = 0.007). Even treatment with cyclophosphamide (CYC) did not decrease CRP levels (p = 0.754). Conclusion Inflammatory SSc is characterized by a more severe phenotype, high morbidity, and a large proportion of male patients. Even treatment with CYC does not alter CRP levels in this subpopulation with a high unmet medical need.

Rituximab therapy is more effective than cyclophosphamide therapy for Japanese patients with anti-topoisomerase I-positive systemic sclerosis-associated interstitial lung disease.

Abstract
Systemic sclerosis-associated interstitial lung disease (SSc-ILD) is the most frequent cause of death for SSc but there is still no sufficient treatment available. Although cyclophosphamide (CYC) therapy is a common treatment which has shown statistical efficacy against SSc-ILD to date, its effects are temporary and not enough. Rituximab (RTX), the anti-CD20 monoclonal antibody, has recently shown efficacy in many autoimmune diseases. In SSc-ILD, RTX is also considered to be one of the novel treatment candidates. However, studies of SSc-ILD in Japanese treated with RTX have only a few case reports. Therefore, in this study, we retrospectively compared nine patients treated with RTX and 30 patients treated with CYC to investigate the efficacy of RTX treatment for Japanese anti-topoisomerase I-positive SSc-ILD patients. At the 24-month evaluation, the improvement rates of percent predicted of forced vital capacity and percent predicted of diffusing capacity of the lung carbon monoxide in the RTX-treated group were significantly higher than those in the CYC-treated group (20.6 ± 8.8% vs 1.1 ± 3.9%; P < 0.05 and 34.0 ± 6.0% vs -1.5 ± 2.8%; P < 0.01, respectively). In addition, skin thickness scores also showed a marked improvement from 13.5 points before the start of treatment to 5.8 points after 24 months by RTX therapy (P < 0.05). These results suggest that RTX treatment is more effective for Japanese SSc-ILD patients than CYC treatment. In the future, it is expected that large-scale clinical trials will show the usefulness of RTX treatment for SSc-ILD.

Abstract
INTRODUCTION/OBJECTIVES Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), mean platelet volume (MPV), and red cell distribution width (RDW) may potentially reflect inflammatory status in systemic autoimmune diseases. The aim of this study is to investigate the association between these proposed markers and disease manifestations, activity, and severity in systemic sclerosis (SSc). METHOD We conducted a cross-sectional study of 69 systemic sclerosis (SSc) patients and 50 healthy volunteers in a single center. Adult patients with SSc and healthy controls were compared in terms of NLR, MLR, MPV, RDW, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Venous blood samples were drawn after at least 8 h of fasting in the morning. Extension of skin fibrosis was evaluated by using modified Rodnan skin score (mRSS). Disease severity and activity were assessed by Medsger disease severity and European Scleroderma Trials and Research Group (EUSTAR) disease activity scores, respectively. Associations of disease manifestations, clinical, laboratory, and capillaroscopic findings, mRSS, and the disease activity and severity scores with the proposed hematological markers were evaluated. Multiple regression models were generated for significant associations. RESULTS The neutrophil number was higher (p = 0.004) and lymphocyte number was lower (p < 0.001) in SSc group compared to controls. SSc group also had higher NLR, MLR, and RDW. In multiple logistic regression, only the NLR (regression coefficient = 3.49, p = 0.031) and CRP (regression coefficient = 0.17, p = 0.037) remained significantly different between SSc and healthy control groups (Cox and Snell R2 = 0.243, Nagelkerke R2 = 0.337, p < 0.001). NLR and MLR positively correlated with mRSS, EUSTAR score, and CRP. MLR also positively correlated with Medsger score. Higher monocyte counts independently predicted higher EUSTAR and Medsger scores in multiple linear regressions. Patients with digital ulcers had higher NLR and MLR. We did not find any difference in MPV values between SSc and healthy control groups. CONCLUSIONS Globally available and inexpensive hematological tests, particularly the NLR and MLR, may be associated with vascular and cutaneous manifestations as well as disease activity and severity in SSc.Key Points• Monocyte count itself independently predicted higher activity and severity scores in SSc.• Globally available and inexpensive hematological markers, particularly the NLR and MLR, may have an association with vascular and cutaneous manifestations as well as disease activity and severity in patients with SSc.

Abstract
There are currently no effective measures to combat fibrosis in modern medical practice. One of the reasons for that is the late diagnosis associated with the lack of available clinical biomarkers and effective methods of non-invasive detection of the process. Fibrosis of the skin is characterized by fibrosis of the dermis, underlying tissues and is represented by a wide range of nosologies. Scleroderma and scars are of the greatest interest for the study. Skin changes in the development of bleomycin-induced fibrosis was studied in the experimental model using laser fluorescence spectroscopy and optical tissue oximetry. A significant increase in the rates of endogenous fluorescence of porphyrins, caused by inflammation and hypoxia, was detected at 7 and 21 days. An increased intensity of endogenous collagen fluorescence and a decreased specific oxygen uptake due to excess accumulation of the extracellular matrix were recorded on the 21st day after bleomycin treatment. Synchronous measurements of the collagen fluorescence and the specific oxygen uptake allowed to correlate the obtained data and the phases of the fibrogenic response described morphologically. The results allow to judge the severity of inflammation and hypoxia in the process of the fibrosis development. The objective and quantitative nature of the recorded parameters makes it possible to develop criteria for diagnosing the phases of fibrosis development.

Abstract
The treatment of systemic sclerosis (SSc) presents a clinical challenge because of the progressive nature of the disease, relatively poor prognosis, and lack of a proven treatment. In the last 10 years, several studies demonstrated the importance of interleukin 6 (IL6) as a pivotal cytokine in the development of fibrosis and angiopathy, especially in SSc. Tocilizumab, an IL6 receptor antibody, has shown promising results for patients with SSc. A total of 16 patients with SSc were treated with tocilizumab; 14 were female and 2 were male, with a median age of 45.5 years and median disease duration of 31.5 months. Ten patients had anti-SCl-70, none had anticentromere, and two had antipolymerase. Tocilizumab treatment was provided as long as the patient's condition improved. Total treatment duration was 30.33 patient-years. Median treatment duration was 18.5 months, and 3 patients were treated for a period of 4 years and longer. Ten patients were treated with tocilizumab to the date of data collection. All were feeling good and maintained the achieved improvement throughout the treatment period. Improvement was recorded in 12 patients (75%). Mean reduction in modified Rodnan skin score was 11 points (p < 0.001), musculoskeletal and joint involvement improved in 75% and 80% of patients, respectively, and improvement in lung function was recorded in 46%. Patients with early SSc responded better to tocilizumab (p = 0.01). This is the largest reported case series of tocilizumab treatment in patients with SSc. The treatment was without significant side-effects and was beneficial for most patients, especially in early disease. The present study reinforces previous findings regarding the efficacy of tocilizumab in treating SSc.

Abstract
Systemic sclerosis (SSc) is a highly heterogeneous disease caused by a complex molecular circuitry. For decades, clinical and molecular research focused on understanding the primary process of fibrosis. More recently, the inflammatory, immunological and vascular components that precede the actual onset of fibrosis, have become a matter of increasing scientific scrutiny. As a consequence, the field has started to realize that the early identification of this syndrome is crucial for optimal clinical care as well as for understanding its pathology. The cause of SSc cannot be appointed to a single molecular pathway but to a multitude of molecular aberrances in a spatial and temporal matter and on the backbone of the patient's genetic predisposition. These alterations underlie the plethora of signs and symptoms which patients experience and clinicians look for, ultimately culminating in fibrotic features. To solve this complexity, a close interaction among the patient throughout its "journey," the clinician through its clinical assessments and the researcher with its experimental design, seems to be required. In this review, we aimed to highlight the features of SSc through the eyes of these three professionals, all with their own expertise and opinions. With this unique setup, we underscore the importance of investigating the role of environmental factors in the onset and perpetuation of SSc, of focusing on the earliest signs and symptoms preceding fibrosis and on the application of holistic research approaches that include a multitude of potential molecular alterations in time in an unbiased fashion, in the search for a patient-tailored cure.

Abstract
Purpose: Extracellular matrix (ECM) deposition and remodelling in skin and lungs of systemic sclerosis (SSc) subjects lead to release of metabolites/biomarkers into circulation. We investigated if biomarkers of ECM degradation (biglycan and elastin) and macrophage activation (citrullinated vimentin) could identify diffuse SSc (dSSc) subjects from controls and the biomarkers discriminative power. Methods: DSSc subjects (n = 40) fulfilling the 2013 EULAR/ACR classification criteria were divided in early (<2years of symptoms) and late (≥10 years of symptoms). Early were subdivided into intermediate and rapid skin thickness progression rate (STPR). Twenty controls were included. Citrullinated and matrix metalloproteinase (MMP)-2/8-degraded vimentin (VICM), MMP-9/12-degraded biglycan (BGM) and MMP-7-degraded elastin (ELM-7) were assessed in serum. Analysis between groups was by Kruskal-Wallis and ROC AUC for discriminative power. Results: VICM and BGM levels were increased in early compared with late dSSc (p< =0.023). VICM was increased in rapid and intermediate STPR compared with controls (p< =0.025). No differences in ELM-7 levels were observed. AUC of VICM was 0.71 for early versus late dSSc and BGM had an AUC of 0.79 for dSSc versus controls. Conclusion: This pilot study found differences in biomarker levels between early and late dSSc. This study offers new perspectives of ECM metabolites as potential biomarkers of dSSc.

Abstract
There have been no established parameters to predict responsiveness to i.v. cyclophosphamide (IVCY) pulse therapy in combination with corticosteroids in patients with interstitial lung disease (ILD) related to systemic sclerosis (SSc). This retrospective study was conducted to determine predictive factors for efficacy of IVCY at the time of before and during the treatment. Thirty-two Japanese SSc patients, ever treated for ILD with IVCY in combination with prednisolone, were analyzed retrospectively. We performed detailed time-course analyses of parameters derived from blood samples and pulmonary function tests. With the exclusion of eight unclassified patients, 24 patients were classified into 14 good responders (GR) or 10 poor responders (PR) on the basis of changes in percent predicted diffusing capacity for carbon monoxide (DLco). Pretreatment percent predicted DLco was significantly reduced in PR compared with GR. In addition, serum parameters such as Krebs von den Lungen-6 (KL-6), surfactant protein D (SP-D) and C-reactive protein were significantly higher in PR than in GR. Furthermore, our time-course analyses revealed a transient increase in serum KL-6 levels with a peak at 3 months after the first infusion of cyclophosphamide, which showed no relation to therapeutic efficacy. Moreover, continuously high serum KL-6 levels (>2000 U/mL) and rapid decrease in SP-D levels (<200 ng/mL) during IVCY were remarkably characteristic of PR and GR, respectively. ILD severity/activity before treatment and variability of serum KL-6 and SP-D levels during treatment may be useful to predict therapeutic effects of IVCY on SSc-ILD.

Abstract
Introduction: Juvenile systemic sclerosis is an orphan disease. Currently, the majority of juvenile systemic sclerosis cohort studies are retrospective in design without standardized assessment. This study was conducted prospectively to investigate the difference in manifestations of limited cutaneous juvenile systemic sclerosis and diffuse cutaneous juvenile systemic sclerosis subtypes. An additional aim was to compare these data to other juvenile systemic sclerosis cohorts and a large adult systemic sclerosis cohort. Methods: Patients fulfilling the Paediatric Rheumatology European Society juvenile systemic sclerosis classification criteria were included. Clinical characteristics and patient-related outcomes were assessed. Results: In all, 88 patients with a mean disease duration of 3.5 years were enrolled, 72.5% with diffuse cutaneous juvenile systemic sclerosis with a mean modified Rodnan Skin score of 18 and 27.5% with limited cutaneous juvenile systemic sclerosis with mean modified Rodnan Skin score of 9. The mean age at the onset of Raynaud’s and first non-Raynaud’s symptoms was similar in both groups, approximately 9 and 10.5 years. Active digital tip ulcerations were present in 29% diffuse cutaneous juvenile systemic sclerosis and none in the limited cutaneous juvenile systemic sclerosis subjects (p = 0.005). Of those with cardiopulmonary testing, 3% of diffuse cutaneous juvenile systemic sclerosis and 23% of limited cutaneous juvenile systemic sclerosis group had cardiac involvement (p = 0.015), and 41% diffuse cutaneous juvenile systemic sclerosis and 22% of the limited cutaneous juvenile systemic sclerosis group had pulmonary involvement (p = 0.009). Physician global disease damage assessment was higher in the diffuse cutaneous juvenile systemic sclerosis group compared to the limited cutaneous juvenile systemic sclerosis group: 35 and 15 (p = 0.021). Discussion: The majority of this international juvenile systemic sclerosis cohort had diffuse cutaneous juvenile systemic sclerosis (72.5%) with more frequent vascular and pulmonary involvement compared to the limited cutaneous group, who had increased cardiac involvement. Our cohort reflects prior findings of published juvenile systemic sclerosis cohorts and emphasizes a difference in the presentation compared to adult-onset systemic sclerosis.

Serum levels of B-cell activating factor of the TNF family (BAFF) correlate with anti-Jo-1 autoantibodies levels and disease activity in patients with anti-Jo-1positive polymyositis and dermatomyositis. Arthritis Res Ther 2018; 20:158. [PMID: 30053824 PMCID: PMC6062864 DOI: 10.1186/s13075-018-1650-8] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Accepted: 06/20/2018] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND B-cell activating factor of the tumour necrosis factor family (BAFF) plays a role in autoantibody production and is elevated in dermatomyositis (DM) and anti-Jo-1-positive polymyositis (PM). We investigated the inter-relationships between serum levels of BAFF, anti-Jo-1 autoantibodies, and disease activity. METHODS Serum levels of BAFF and anti-Jo-1 antibodies measured by enzyme-linked immunosorbent assay (ELISA) were compared to levels of myoglobin, creatine kinase (CK), aminotransferases (alanine (ALT) and aspartate (AST)), C-reactive protein (CRP), and disease activity assessed by the Myositis Disease Activity Assessment Tool in 63 anti-Jo-1 antibody-positive DM/PM patients. Serial serum samples collected at 2 (46 cases) and 3-5 time points (23 cases) were included. Relationships between BAFF, anti-Jo-1, disease activity, CRP, and their longitudinal changes were evaluated using correlation analysis, multiple regression (MR), path analysis (PA), and hierarchical linear models (HLM). RESULTS Cross-sectional assessment demonstrated significant correlations between the levels of BAFF and anti-Jo-1 antibodies which were associated with levels of CK, myoglobin, AST, and CRP, as well as multivariate associations between BAFF, anti-Jo-1 antibodies, and CK levels. PA revealed direct effects of anti-Jo-1 antibodies on CK (β = 0.41) and both direct (β = 0.42) and indirect (through anti-Jo-1 antibodies; β = 0.17) effects of BAFF on CK. Changes in levels of both BAFF and anti-Jo-1 between two time points (Δ) were associated with Δmyoglobin and Δaminotransferases and changes of BAFF correlated with ΔCK, Δcutaneous, Δmuscle, Δglobal, and Δskeletal disease activities. The longitudinal analysis showed a high intra-individual variability of serum levels of BAFF over time (97%) which could predict 79% of the variance in anti-Jo-1 levels. The anti-Jo-1 variability was explained by inter-individual differences (68%). The close longitudinal relationship between levels of BAFF, anti-Jo-1, and disease activity was supported by high proportions of their variance explained with serum levels of CK and CRP or pulmonary and muscle activities. CONCLUSION Our findings of associations between levels of BAFF and anti-Jo-1 antibodies in serum and myositis activity suggest a role of this cytokine in disease-specific autoantibody production as part of disease mechanisms, and support BAFF as a potential target for intervention in anti-Jo-1-positive myositis patients.

Prevalence of sarcopenia in systemic sclerosis: assessing body composition and functional disability in patients with systemic sclerosis. Nutrition 2018; 55-56:51-55. [PMID: 29960157 DOI: 10.1016/j.nut.2018.03.046] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Revised: 03/14/2018] [Accepted: 03/22/2018] [Indexed: 12/23/2022]
Abstract
OBJECTIVE We analyzed the prevalence of sarcopenia among systemic sclerosis (SSc) patients with respect to quality of life, disability, organ involvement, and muscle function. METHODS A total of 129 patients who met the ACR/EULAR 2013 classification criteria were included. Body composition was measured using bioelectric impedance analysis. Sarcopenia was defined according to the criteria of the European Working Group on Sarcopenia in Older People. Handgrip and knee extension strength and pulmonary peak flow were measured. Physical function was assessed with the Short Form-36 Health Survey and Scleroderma Health Assessment Questionnaire. RESULTS Sarcopenia was prevalent in 22.5% of patients. There were significant differences between patients with and without sarcopenia regarding handgrip strength (11.5 [2.0-30.0] versus 18.0 [1.0-41.0] kilogram force [kgf]; P <0.001) and knee extension strength (11.0 [3.5-32.5] versus 17.5 [3.5-88.0] kgf; P = 0.006), physical function (38.8 [9.9-85.0] versus 48.8 [0-88.0]; P = 0.032) and number of immunosuppressants (2 [0-4] versus 1 [0-5]; P = 0.009). There were no differences regarding age (57.0 [32.0-83.0] versus 60.5 [28.0-82.0] years; P = 0.350) and disease duration (8 [1-27] versus 7 [0-34] years; P = 0.350). CONCLUSIONS Sarcopenia is common in patients with SSc and is associated with physical impairment that affects everyday life and participation in work. Interestingly, although age is the main risk factor for sarcopenia in the general population, it did not differ between sarcopenic and non-sarcopenic SSc patients in our study. Instead, the number of immunosuppressive drugs was significantly higher among sarcopenic patients.

Abstract
Objective This study was performed to evaluate the serum amyloid A (SAA) and C-reactive protein (CRP) levels in patients with diffuse systemic sclerosis (dSSc) in relation to a control group, disease duration, and skin and pulmonary involvement. Methods This case-control study included 18 patients with early dSSc, 15 patients with late dSSc, and 15 healthy controls. The SAA and CRP levels, modified Rodnan skin score (mRSS), and diffusing capacity of the lungs for carbon monoxide (DLCO) were determined in all patients. Results The SAA and CRP levels were significantly higher in patients with early and late dSSc than in healthy controls. The frequency of detection of elevated SAA and CRP levels was approximately 66% and 85%, respectively. A significant correlation was found between the SAA and CRP levels in patients with dSSc. The SAA and CRP levels were inversely correlated with DLCO. The CRP level was positively correlated with the mRSS. Conclusions High SAA and CRP levels could serve as biomarkers for pulmonary involvement. The serum CRP level accurately reflects the extension of skin thickening in patients with dSSc.

Abstract
Objective Antinuclear antibodies (ANA) serve as screening tests for connective tissue diseases but have low specificity. In this pilot study, we aimed to identify patients with first-time positive ANA and musculoskeletal complaints and correlate serum soluble vascular adhesion molecules as biomarkers. Methods Prospective, observational study with 100 ANA-positive patients, comparing them to age- and gender-matched healthy controls (HC, n = 75), was conducted. Serum levels of soluble intercellular adhesion molecule-1 (sICAM-1), endothelial-leukocyte adhesion molecule-1 (sELAM-1), and vascular cell adhesion molecule-1 (sVCAM-1) were measured. A subgroup of patients with systemic sclerosis (SSc) treated with immunosuppressants was followed over 10 months. Results Patients belonged to three main entities: rheumatoid arthritis (RA, n = 32), collagen diseases (CD, n = 56) also including systemic sclerosis (SSc, n = 11), and other autoimmune diseases (n = 12). sICAM-1 was similar among groups. sELAM-1 was elevated by 1.9-fold in only in SSc. sVCAM-1 was elevated by 3.1-fold in RA and by 3.3-fold in CD and in other autoimmune diseases by 3.4-fold. Seven SSc patients with immunosuppression had a 2.7-fold increased sVCAM-1 at baseline and reached the levels of healthy controls after 5 months, while CRP, ESR, and clinical parameters remained unchanged. Conclusion Our study suggests that sVCAM-1 is a disease marker independent of standard serum parameters in several rheumatic diseases. This study is registered with EU PAS Register number: EUPAS22154.

Abstract
Background There is an ongoing debate regarding the relevance of the 6-minute walking distance (6MWD) in systemic sclerosis (SSc) assessment, widely used as a usual test in these patients as well as an outcome measure in clinical trials. In this work, we aimed to assess the associations between the 6MWD and various disease parameters in patients with SSc. Methods Consecutive patients followed in our SSc National Reference Centre were included in this cross-sectional study if they fulfilled the 2013 American College of Rheumatology/European League Against Rheumatism criteria for SSc. Data were systematically collected during a comprehensive standardized evaluation that included a 6-minute walk test, clinical assessment, biological results, pulmonary function tests, transthoracic echocardiography, composite scores (European Scleroderma Study Group Activity Index, Medsger severity score, Health Assessment Questionnaire–Disability Index (HAQ-DI)) and treatments. Associations of the 6MWD with various disease parameters were assessed by linear regression in univariate and multivariate analyses. Results The study population comprised 298 patients (females 81%; mean age 58.2 ± 13.3 years; limited cutaneous SSc 82%; interstitial lung disease (ILD) 42%; pulmonary arterial hypertension (PAH) 6%). The 6MWD was significantly and independently associated with gender, age, body mass index, baseline heart rate (HR), HR variation during the test, PAH, history of arterial thrombosis and C-reactive protein levels, as well as with the HAQ-DI score in a sensitivity analysis. Muscle involvement, joint involvement and ILD were not independently associated with the 6MWD. Conclusions During SSc, the 6MWD is independently associated with initial HR and HR variation; with PAH but not ILD, suggesting that pulmonary vasculopathy may have a greater impact than parenchymal involvement on functional limitation; and with global markers of disease activity and patient disability. These results give clinicians further insight into how to interpret the 6MWD in the context of SSc.

Abstract
To investigate the frequency, severity and predictors of interstitial lung disease (ILD) in a cohort of South Africans with systemic sclerosis (SSc). Retrospective record review of SSc patients attending a tertiary Connective Tissue Diseases Clinic. Patients with ILD, defined by a combination of clinical findings, imaging, and lung function tests were compared to patients without ILD in terms of demographics, clinical features and autoantibodies. The majority (86.8%) of the 151 patients included were of Black ethnicity, 40% had ILD, of whom 39% had moderate-severe lung disease. Univariate predictors of ILD included: disease duration (OR 1.08, 95% CI 1.01-1.15); cough (OR 2.93, 95% CI 1.37-6.29); dyspnoea (OR 2.44, 95% CI 1.23-4.87); bibasal crackles (OR 7.58, 95% CI 3.31-17.37); diffuse cutaneous SSc (dcSSc) (OR 4.55, 95% CI 2.10-9.86) and a speckled anti-nuclear antibody (ANA) pattern (OR 2.47, 95% CI 1.25-4.90). Conversely, limited cutaneous disease (OR 0.22, 95% CI 0.09-0.50) and anti-centromere antibody (ACA) (OR 0.12, 95% CI 0.02-0.97) were protective. Independent predictors of ILD on multivariate analysis were bibasal crackles (OR 9.43, 95% CI 3.25-27.39), disease duration (OR 1.19, 95% CI 1.09-1.30) and speckled ANA (OR 2.95, 95% CI 1.22-7.15). Almost all (86.4%) patients received immunosuppressive treatment and the leading cause of death was related to ILD itself (44.4%). In this cohort of predominantly Black South Africans, SSc ILD was common and carried a poor prognosis. ILD occurred mainly, but not exclusively, in patients with dcSSc, especially those with a speckled ANA pattern. Conversely, the presence of ACA was protective against ILD.

Abstract
Objectives Assess the efficacy and safety of tocilizumab in patients with systemic sclerosis (SSc) in a phase II study. Methods Patients with SSc were treated for 48 weeks in an open-label extension phase of the faSScinate study with weekly 162 mg subcutaneous tocilizumab. Exploratory end points included modified Rodnan Skin Score (mRSS) and per cent predicted forced vital capacity (%pFVC) through week 96. Results Overall, 24/44 (55%) placebo-tocilizumab and 27/43 (63%) continuous-tocilizumab patients completed week 96. Observed mean (SD (95% CI)) change from baseline in mRSS was –3.1 (6.3 (–5.4 to –0.9)) for placebo and –5.6 (9.1 (–8.9 to–2.4)) for tocilizumab at week 48 and –9.4 (5.6 (–8.9 to –2.4)) for placebo-tocilizumab and –9.1 (8.7 (–12.5 to –5.6)) for continuous-tocilizumab at week 96. Of patients who completed week 96, any decline in %pFVC was observed for 10/24 (42% (95% CI 22% to 63%)) placebo-tocilizumab and 12/26 (46% (95% CI 27% to 67%)) continuous-tocilizumab patients in the open-label period; no patients had >10% absolute decline in %pFVC. Serious infection rates/100 patient-years (95% CI) were 10.9 (3.0 to 27.9) with placebo and 34.8 (18.0 to 60.8) with tocilizumab during the double-blind period by week 48 and 19.6 (7.2 to 42.7) with placebo-tocilizumab and 0.0 (0.0 to 12.2) with continuous-tocilizumab during the open-label period. Conclusions Skin score improvement and FVC stabilisation in the double-blind period were observed in placebo-treated patients who transitioned to tocilizumab and were maintained in the open-label period. Safety data indicated increased serious infections in patients with SSc but no new safety signals with tocilizumab. Trial registration number NCT01532869; Results.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a chronic autoimmune disease characterised by tissue fibrosis and immune abnormalities. Recent evidence suggests that activated circulating monocytes from patients with SSc play an important role in early stages of SSc pathogenesis due to enhanced expression of tissue inhibitor of metalloproteinases 1 (TIMP-1), IL-8 and reactive oxygen species (ROS) induction. However, the exact factors that contribute to chronic inflammation and subsequently fibrosis progression are still unknown. MATERIALS AND METHODS The expression pattern of IL-8, TIMP-1, AP-1 transcription factor-Fra2 and ROS induction in peripheral blood monocytes following DZNep (histone methyltransferase inhibitor) and TLR8 agonist stimulation was investigated. Exogenous microRNA-5196, which is predicted to bind 3'UTR of Fra2 gene, was delivered to reverse profibrotic phenotype in monocytes. Expression of circulating microRNA-5196 was correlated with SSc parameters. RESULTS DZNep + TLR8 agonist stimulation enhanced profibrotic TIMP-1, IL-8 and ROS generation in HC and SSc monocytes. As opposed by the decrease of miRNA-5196 and antioxidant SOD1 expression in SSc monocytes. Exogenous delivery of microRNA-5196 reduced Fra2 and TIMP-1 expression suggesting that it may be used as a potential modulator of fibrogenesis in SSc. Circulating microRNA-5196 was significantly increased in SSc and positively correlated with CRP level but not with Rodnan skin score or ESR. CONCLUSIONS These results suggest that microRNA-5196 can be used as a potential biomarker characterising SSc. Overall, this study may open new possibilities for the development of microRNA-5196-based diagnostics and therapy in early phases of SSc.

Abstract
OBJECTIVE Imatinib has been investigated for the treatment of systemic sclerosis (SSc) because of its ability to inhibit the platelet-derived growth factor receptor and transforming growth factor-β signaling pathways, which have been implicated in SSc pathogenesis. In a 12-month open-label clinical trial assessing the safety and efficacy of imatinib in the treatment of diffuse cutaneous SSc (dcSSc), significant improvements in skin thickening were observed. Here, we report our analysis of sera collected during the clinical trial. METHODS We measured the levels of 46 cytokines, chemokines, and growth factors in the sera of individuals with dcSSc using Luminex and ELISA. Autoantigen microarrays were used to measure immunoglobulin G reactivity to 28 autoantigens. Elastic net regularization was used to identify a signature that was predictive of clinical improvement (reduction in the modified Rodnan skin score ≥ 5) during treatment with imatinib. The signature was also tested using sera from a clinical trial of nilotinib, a tyrosine kinase inhibitor that is structurally related to imatinib, in dcSSc. RESULTS The elastic net algorithm identified a signature, based on levels of CD40 ligand, chemokine (C-X-C motif) ligand 4 (CXCL4), and anti-PM/Scl-100, that was significantly higher in individuals who experienced clinical improvement than in those who did not (p = 0.0011). The signature was validated using samples from a clinical trial of nilotinib. CONCLUSION Identification of patients with SSc with the greatest probability of benefit from treatment with imatinib has the potential to guide individualized treatment. Validation of the signature will require testing in randomized, placebo-controlled studies. Clinicaltrials.gov NCT00555581 and NCT01166139.

Abstract
BACKGROUND As intravenous immunoglobulins (IVIG) exhibit immunomodulatory and antifibrotic properties, they may be a relevant treatment for systemic sclerosis (SSc). The objectives of this work were thus to report on the efficacy and safety of IVIG in a population of SSc patients and to review the available literature. METHODS 46 patients from 19 French centers were retrospectively recruited. They were included if they had a diagnosis of SSc and received at least 1 IVIG infusion at a dosage >1g/kg/cycle. Relevant data collected at IVIG discontinuation were compared to those collected at IVIG initiation. A comprehensive literature review was performed. RESULTS We observed a significant improvement of muscle pain (74% vs. 20%, p<0.0001), muscle weakness (45% vs. 21%, p=0.01), joint pain (44% vs. 19%, p=0.02), CK levels (1069±1552UI vs. 288±449UI, p<0.0001) and CRP levels (13.1±17.6mg/L vs. 9.2±16.6mg/L, p=0.001). We also noted a trend for an improvement of gastro-esophageal reflux disease (68% vs. 53%, p=0.06) and bowel symptoms (42% vs. 27%, p=0.06). Skin and cardiorespiratory involvements remained stable. Finally, corticosteroid daily dose was significantly lower by the end of treatment (13.0±11.6mg/day vs. 8.9±10.4mg/day, p=0.01). Only two severe adverse events were reported (one case of deep vein thrombosis and one case of diffuse edematous syndrome). CONCLUSION Our work suggests that IVIG are a safe therapeutic option that may be effective in improving musculoskeletal involvement, systemic inflammation, digestive tract symptoms and could be corticosteroid sparing.

Abstract
Serum prealbumin is a recognized marker of malnutrition, but its prognostic role in patients with hemorrhagic stroke remains unclear. In this study, we retrospectively reviewed the records of 105 patients with hemorrhagic stroke admitted to Renmin Hospital of Wuhan University, China, from January to December 2015. We collected demographic and radiological data, and recorded serum prealbumin levels at admission and on days 1, 3, 6, 9, and 14–21. The existence of infections and gastrointestinal hemorrhage, and clinical condition at discharge were also recorded. Serum prealbumin levels during hospitalization were significantly lower in patients with infections compared with those without infections, and also significantly lower in patients with gastrointestinal hemorrhage compared with those without. Serum prealbumin levels at discharge were significantly higher in patients with good recovery than in those with poor recovery. We conclude that regular serum prealbumin measurements in patients with hemorrhagic stroke may be a useful indicator for determining clinical status and prognosis, which may therefore help to guide clinical decision-making.
