Abstract
OBJECTIVES Heart involvement is one of the leading causes of death in systemic sclerosis (SSc). The prevalence of SSc-related cardiac involvement is poorly known. Our objective was to investigate the prevalence and prognosis burden of different heart diseases in a nationwide cohort of patients with SSc. METHODS We used data from a multicentric prospective study using the French SSc national database. Focusing on SSc-related cardiac involvement, we aimed to determine its incidence and risk factors. RESULTS Over the 3528 patients with SSc 312 (10.9%) had SSc-related cardiac involvement at baseline. They tended to have a diffuse SSc subtype more frequently, more severe clinical features, and presented more cardiovascular risk factors. From the 1646 patients available for follow-up analysis, SSc-related cardiac involvement was associated with an increased risk of death. There was no significant difference in overall survival between SSc-related cardiac involvement, ischaemic heart disease or pulmonary arterial hypertension. Regarding survival analysis, 98 patients developed SSc-related cardiac involvement at five years (5-year event rate: 11.15%). Regarding reduced LVEF < 50% and left ventricular diastolic dysfunction, the 5-year event rate was 2.49% and 5.84% respectively. Pericarditis cumulative incidence at five years was 3%. Diffuse SSc subtype was a risk factor for SSc-related cardiac involvement and pericarditis. Female sex was associated with less left ventricular diastolic dysfunction incidence. CONCLUSIONS Our results describe the incidence and prognostic burden of SSc-related cardiac involvement at a large scale, with gender and diffuse SSc subtype as risk factors. Further analyses should assess the potential impact of treatment on these various cardiac outcomes.

Abstract
OBJECTIVE Giant cell arteritis (GCA) is the most common systemic vasculitis in individuals aged ≥50 years. Its course is marked by a high relapse rate requiring long-term glucocorticoid use with its inherent adverse effects. We aimed to identify factors associated with relapses or recurrences in GCA at diagnosis. METHODS We reviewed the medical records of consecutive patients with GCA diagnosed between 2009 and 2019 and followed for at least 12 months. We recorded their characteristics at onset and during follow-up. Factors associated with relapses or recurrences were identified using multivariable analysis. RESULTS We included 153 patients, among whom 68% were female with a median age of 73 (47-98) years and a median follow-up of 32 (12-142) months. Seventy-four patients (48.4%) had at least 1 relapse or recurrence. Headache and polymyalgia rheumatica were the most frequent manifestations of relapses. The first relapse occurred at a median time of 13 months after the diagnosis, with a median dose of 5.5 (0-25) mg/d of glucocorticoids.In multivariable analysis, patients with relapses or recurrences had a higher frequency of cough and scalp tenderness at diagnosis (20.3% vs 5.1%; odds ratio [OR], 4.73; 95% confidence interval [CI], 1.25-17.94; p = 0.022; and 41.9% vs 29.1%; OR, 2.4; 95% CI, 1.07-5.39; p = 0.034, respectively). Patients with diabetes mellitus at diagnosis had fewer relapses or recurrences during follow-up (5.4% vs 19%; OR, 0.24; 95% CI, 0.07-0.83; p = 0.024). CONCLUSIONS Cough and scalp tenderness at diagnosis were associated with relapses or recurrences, whereas patients with diabetes experienced fewer relapses or recurrences.

Abstract
OBJECTIVE Life habits (LH) encompass an individual's engagement in daily activities such as nutrition, fitness, personal care, communication, housing, and mobility, along with his/her social role (responsibility, interpersonal relationships, community life, education, employment, and recreation). This qualitative study explores the nature and context of LH restrictions in systemic lupus erythematosus (SLE) individuals across their SLE journey. METHODS Narrative interviews were conducted with adult SLE patients. Interview transcripts were subjected to a thematic content analysis, using the Disability Creation Process model as a framework. RESULTS Forty participants were interviewed. Three major themes were highlighted: (1) Temporality, capabilities, and environmental contexts: although all participants experienced LH restrictions at some point, the expression of these limitations depended on the individual's and SLE disease characteristics as well as on temporal (time of life and lupus course) and environmental (material, social, and societal) contexts. (2) Identity issues, illness stigma, and (fear of) discriminations: LH were discussed through the lens of participants' social roles and identities. While illness stigma can influence social relations, it is also expressed at a societal level. (3) Masking and minimizing strategies: due to illness stigma and fear of discrimination, participants developed strategies to manage their relationships, including masking and minimization. Their use was both advantageous and disadvantageous regarding LH. CONCLUSIONS For individuals with SLE, LH restrictions must be considered as an ongoing process that takes place within specific contexts. Our findings provide many opportunities for interventions that can benefit patients and their families, as well as healthcare providers.

Abstract
OBJECTIVE Giant cell arteritis (GCA) is the most frequent vasculitis affecting adults aged > 50 years. Cardiac involvement in GCA is considered rare, and only a few cases of pericarditis have been reported. The aim of this study was to determine the characteristics and prognosis of GCA patients suffering from pericardial involvement at diagnosis. METHODS We conducted a single-centre, retrospective chart review of patients with GCA in internal medicine departments (from 2000 to 2020). Patients were identified through a centralized hospital database. We retrospectively collected demographic, clinicobiological, histological, imaging, treatment and outcome data. Patients with pericardial effusion, defined as an effusion visible on the CT-scan performed at GCA diagnosis were compared to those without pericardial involvement. RESULTS Among the 250 patients with GCA, 23 patients (9.2%) had pericardial effusion on CT-scan. The comparison between the groups revealed similar distribution of age, gender, cranial symptoms and ocular ischaemic complications. Patients with pericardial effusion had a higher frequency of weight loss. They also had lower haemoglobin levels and higher platelet levels (p = 0.006 and p = 0.002, respectively), and they more frequently had positive temporal artery biopsy. There were no differences concerning the treatment, relapses, follow-up duration or deaths. CONCLUSIONS This case series sheds light on GCA as a cause of unexplained pericardial effusion or symptomatic pericarditis among adults aged > 50 years and elevated inflammatory biological markers. Fortunately, pericardial involvement is a benign GCA manifestation. In that context, the search for constitutional symptoms, cranial symptoms and associated signs of polymyalgia rheumatica is crucial for rapidly guiding GCA diagnosis.

Multisystem inflammatory syndrome-related refractory cardiogenic shock in adults after coronavirus disease 2019 infection: a case series. Eur Heart J Case Rep 2022; 6:ytac112. [PMID: 35475192 PMCID: PMC8992241 DOI: 10.1093/ehjcr/ytac112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 07/01/2021] [Accepted: 03/08/2022] [Indexed: 11/28/2022]
Abstract
Background A novel multisystem inflammatory syndrome in children (MIS-C) temporally associated with the coronavirus disease 2019 (COVID-19) infection has been reported, arising weeks after the peak incidence of COVID-19 infection in adults. Patients with MIS-C have been reported to have cardiac involvement and clinical features overlapping with other acute inflammatory syndromes such as Kawasaki disease, toxic shock syndrome, and macrophage activation syndrome. Multisystem inflammatory syndrome in children may follow COVID-19 infection, most of the time after its asymptomatic form, even though it can lead to serious and life-threatening illness. Case summary In this case series, we discuss two cases of young adults with no former medical history who fit with the criteria defined in MIS-C. They both developed a refractory cardiogenic shock and required intensive care treatment including mechanical circulatory support, specifically the use of venous–arterial extracorporeal membrane oxygenation. They were both treated early with intravenous immune globulin and adjunctive high-dose steroids. They recovered ad integrum in less than 2 weeks. Discussion Multisystem inflammatory syndrome in children occurs 2–4 weeks after infection with severe acute respiratory syndrome coronavirus 2. Patients with MIS-C should ideally be managed in an intensive care environment since rapid clinical deterioration may occur. It would be preferable to have a multidisciplinary care to improve outcomes. Patients should be monitored for shock. Elucidating the mechanism of this new entity may have importance for understanding COVID-19 far beyond the patients who have had MIS-C to date. The pathogenesis seems to involve post-infectious immune dysregulation so early administration intravenous immune globulin associated with corticosteroids appears appropriate. It implies early recognition of the syndrome even in young adults.

Abstract
OBJECTIVE To assess the superiority of adipose tissue-derived stromal vascular fraction (AD-SVF) injection into the fingers vs placebo in reducing hand disability in systemic sclerosis (SSc) patients. METHODS We performed a double-blind, multicentre, phase II trial from October 2015 to January 2018 in France. SSc patients with a Cochin Hand Function Scale (CHFS) ≥20/90 were randomized 1:1 to receive injection of AD-SVF or placebo. AD-SVF was obtained using the automated processing Celution®800/CRS system. The placebo was lactated Ringer's solution. The primary efficacy end point was the change of the CHFS score from baseline to 3 months. Secondary efficacy endpoints included the CHFS score at 6 months, hands function, vasculopathy, hands pain, skin fibrosis, sensitivity of the finger' pulps, Scleroderma Health Assessment Questionnaire, patients and physician satisfaction and the safety. RESULTS 40 patients were randomized. The AD-SVF and placebo groups were comparable for age, sex ratio, disease duration, skin fibrosis of the hands and main cause of hand disability. After 3 month-follow-up, hand function significantly improved in both groups with no between-group difference of CHFS (mean change of -9.2 ± 12.2 in the AD-SVF group vs -7.6 ± 13.2 in the placebo group). At 6 months, hand function improved in both groups. CONCLUSION This study showed an improvement of hand function in both groups other time, with no superiority of the AD-SVF. Considering the limits of this trial, studies on a larger population of patients with homogeneous phenotype and hand handicap, should be encouraged to accurately assess the benefit of AD-SVF therapy.

Abstract
Background: The detection of additional autoantibodies is of great concern in systemic sclerosis (SSc) when those included in the ACR/EULAR classification are negative. In this context, the interest of antifibrillarin (anti-U3RNP) autoantibodies (AFAs) in the routine evaluation of SSc remains unclear. We aimed to assess the relevance of AFAs and their clinical association in SSc patients. Methods: In a multicenter observational retrospective study, we collected immunological and clinical data associated with AFA positivity in SSc (n = 42) and non-SSc patients (n = 13). Patients with SSc negative for AFAs (n = 83) were considered as a control group. AFAs were detected by indirect immunofluorescence (IIF) using HEp-2 cells, EliA or immunoblot techniques. Results: We confirmed a typical nuclear IIF pattern and showed that AFAs are mostly exclusive towards SSc conventional autoantibodies. Although also observed in non-SSc patients, high levels of AFAs with the ELiA technique allowed the diagnosis of SSc. Compared to AFA-negative SSc patients, AFA-positive SSc patients more frequently exhibited visceral involvements. They more frequently suffered from the diffuse cutaneous form and had a higher global severity of the disease. Conclusions: We demonstrate the usefulness of quantifying AFAs in the immunological exploration of SSc, especially when patients are seronegative for SSc conventional autoantibodies and display a typical IIF pattern. AFAs might constitute an interesting marker of SSc severity.

Abstract
OBJECTIVE Patients with inflammatory myopathies (IM) are known to have an increased risk of developing malignancies. Autoimmune and inflammatory diseases occur in up to 25% of patients with myelodysplastic syndrome (MDS). This study aimed to describe the rare association between IM and MDS. METHODS We report here the main characteristics, treatment, and outcome of 21 patients (11 national cases and 10 additional cases from a literature review) with IM associated to MDS. RESULTS Median age of patients at IM diagnosis was 66 years (range 26 - 78). Diagnosis of the two conditions were concomitant in most patients (n=14/21) whereas MDS diagnosis preceded IM diagnosis in 5 patients. Different types of IM were observed but dermatomyositis was the most frequent (59%). Compared to IM without MDS (IM/MDS-), patients with MDS (IM/MDS+) were older (median 66 vs 55, p=0.3), more frequently male (sex ratio M/F 1.125 vs 0.41, p=0.14) and positive for anti-TIF1γ (24% vs 4%, p=0.0039). Antisynthetase syndrome was never observed among IM/MDS+ patients (0% vs 28%, p=0.01). MDS WHO type was not univocal, but the prognostic score was of low risk in almost all cases. IM was usually steroid sensitive (82% of patients) but often steroid dependent (56% of patients). Overall survival of IM patients with MDS was worse compared to patients with IM without MDS (p=0.0002). CONCLUSION IM associated with MDS are mainly represented by dermatomyositis and/or anti-TIF1γ autoantibodies. Antisynthetase syndrome has not been described in association with MDS. Despite low-risk MDS, overall survival of IM patients with MDS is worse than IM patients without MDS.

Abstract
Acute severe hepatitis is a rare complication of adult-onset Still's disease (AOSD). This condition is poorly characterized. We performed a review of the medical literature to describe clinical, biological, pathological, and treatment characteristics from AOSD patients with acute severe hepatitis. Their characteristics were compared with AOSD patients without severe hepatitis. Twenty-one cases were collected including a new case reported here. Patients with severe hepatitis were mostly young adults with a median age of 28 years (range: 20 to 55 years). Overall, patients with severe hepatitis had less arthritis, macular rash, sore throat, lymphadenopathy, or splenomegaly than patients without severe hepatitis. Cytopenia was more frequent in case of severe hepatitis. Most patients were treated with steroids, and the use of biotherapies has increased over the last decade. Despite treatment, 49% of patients required liver transplantation and 24% died. Key Points • Acute severe hepatitis in adult-onset Still's disease (AOSD) is associated with liver transplantation and/or death in, respectively, 43% and 24% of cases. • Severe hepatitis is the inaugural manifestation of AOSD in half of cases. Diagnosis is difficult when extra-hepatic clinical manifestations are lacking. • The mechanism of hepatic necrosis in AOSD with severe hepatitis is unknown. Liver biopsy is not specific and should not delay treatment initiation.

Abstract
We report the case of a 72-y-old man with concomitant autoimmune encephalitis and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The patient presented with subacute cerebellar syndrome and myoclonus several days after general infectious symptoms began. Methods: Clinical examination, CT, PET, MRI, and autoantibody testing were performed. Results: The oropharyngeal swab test was positive for SARS-CoV-2. The brain MRI results were normal. Cerebrospinal fluid testing showed normal cell counts, a negative result on reverse-transcription polymerase chain reaction testing, and no oligoclonal banding. Brain 18F-FDG PET showed diffuse cortical hypometabolism associated with putaminal and cerebellum hypermetabolism, compatible with encephalitis and especially cerebellitis. The immunologic study revealed high titers of IgG autoantibodies in serum and cerebrospinal fluid directed against the nuclei of Purkinje cells, striatal neurons, and hippocampal neurons. Whole-body 18F-FDG PET and CT scans did not show neoplasia. Treatment with steroids allowed a rapid improvement in symptoms. Conclusion: This clinical case argues for a possible relationship between SARS-CoV-2 infection and autoimmune encephalitis and for the use of 18F-FDG PET in such a context.

Abstract
INTRODUCTION Putscher-like retinopathy is a retinal disease that is similar to the syndrome initially described in 1910 by Purtscher, but occurring in a non-traumatic context. CASE REPORT We describe a case of acute, Putscher-like retinopathy in a 48-year-old woman experiencing adult onset Still's disease. The diagnosis was based on fundus examination and fluorescein angiography. Based on a review of the literature, we discuss the current available data on the pathophysiology of this syndrome and its prognostic significance. The treatment remains controversial. CONCLUSION When visual functional signs appear during adult Still's disease, it is necessary to evoke Putscher-like retinopathy, and to ask for an ophthalmological expertise.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a severe and highly heterogeneous disease. The modified Rodnan skin score (mRSS) is a widely used tool for the assessment of the extent and degree of skin thickness. This study aimed to identify the classes of patients with early similar skin thickening trajectories without any a priori assumptions and study their associations with organ involvement and survival. METHODS From the French SSc national cohort, patients with a disease duration of less than 2 years at inclusion and with at least 2 mRSS available within the first 4 years of follow-up were enrolled. Classes of patients with similar mRSS trajectories were identified based on a latent class mixed model. The clinical characteristics and survival rate were compared between the obtained classes. RESULTS A total of 198 patients fulfilled the inclusion criteria, with a total of 641 mRSS available. The median disease duration and follow-up were 0.8 (interquartile range 0.4; 1.2) and 6.3 (3.8; 8.9) years, respectively. Individual trajectories of mRSS were highly heterogeneous between patients. Models with 1-6 latent classes of trajectories were sequentially assessed, and the 5-class model represented the best fit to data. Each class was characterized by a unique global trajectory of mRSS. The median disease duration did not differ significantly between classes. Baseline organ involvement was more frequent in classes with significant change over time (classes 2-5) than in class 1 (low baseline mRSS without significant change over time). Using Cox regression, we observed a progressively increasing risk of death from classes 1 to 5. CONCLUSIONS Early identification of clinical phenotype based on skin thickening trajectories could predict morbi-mortality in SSc. This study suggested that mRSS trajectories characterization might be pivotal for clinical practice and future trial designs.

Abstract
Patients with sickle cell disease have an increased risk of venous thromboembolism (VTE) and with a mortality 2-fold higher. The anticoagulation of VTE in a young population is an important question. Indeed, hemorrhagic complications of anticoagulation may occur more frequently than in the general population. The use of a direct oral anticoagulant (DOAC) is not recommended for VTE in patients with sickle cell disease because those patients were not included in the clinical studies. We aimed to study the safety of using DOACs in a prospective cohort of patients with sickle cell disease and VTE. We prospectively followed the cohort of all sickle cell disease patients undergoing recent DOAC treatment for VTE at a sickle cell disease reference center. Twelve patients received rivaroxaban for VTE (eight women and four men). The median age was 27 years (20-45). The sickle cell disease variants included homozygous Hb SS (HBB: c.20A>T) in eight patients, Hb S-β+-thalassemia (Hb S-β+-thal) in two, Hb S-β0-thal in one and Hb S-Hb C (HBB: c.19G>A) in one. The cumulative duration of follow-up was 3134 days under rivaroxaban treatment. There were two thrombotic events, including a patient with a double positivity of antiphospholipid antibodies. No major bleeding was observed, and 6/12 patients presented minor bleeding (epistaxis: n = 4; anal fissure bleeding: n = 1; menorrhagia n = 4). Of these, 3/6 required their treatment to be switched to apixaban, which stopped the bleeding. Direct oral anticoagulants may be an alternative treatment for VTE in patients with sickle cell disease, except for an associated antiphospholipid syndrome.

Abstract
INTRODUCTION Adrenal hemorrhage is a classical but rare complication of antiphospholipid syndrome, revealing diagnosis in one third of the cases. Anti-vitamin K therapy is the standard treatment but direct oral anticoagulants are discussed as an alternative. In the latest recommendations, it is advised not to use direct oral anticoagulants in the setting of antiphospholipid syndrome. CASE REPORT We present a case of bilateral adrenal hemorrhage revealing primary antiphospholipid syndrome with triple positive antibody profile, in a 47-year-old man treated by apixaban for previous venous thromboembolism. CONCLUSION To our knowledge, it is the first case of adrenal hemorrhage occurring during apixaban treatment in a patient with antiphospholipid syndrome. This case illustrates the inefficacy of direct oral anticoagulants to prevent thrombotic events in antiphospholipid syndrome, in accordance with the latest recommendations.

Abstract
BACKGROUND We conducted a monocentric retrospective study of patients with myelodysplastic syndromes (MDS) and autoimmune or inflammatory disorders (AIMs) and a literature review. We analyzed the association with subgroups of the WHO 2016 MDS classification and patient's survival in a case control study. Risk factors associated with survival were analyzed by uni- and multivariate analysis. RESULTS From all MDS patients 11% presented with AIMs. These were heterogeneous and the most frequent where polyarthritis (25%) and autoimmune cytopenias (17%). No difference for frequency and type of AIMs was observed for the WHO 2016 MDS subgroups (p = .3). In the case control study WHO classification, karyotype abnormalities, IPSS-R and IPSS were similar in both groups. The overall survival from MDS diagnosis was better in the group with AIMs [10.3 ± 0.6 (IC95% 6.2-12.9) versus 4.8 ± 1.1 years (IC95% 4.2-8.7), p = .04]. The better survival was restricted to MDS with low or intermediate-1 IPSS [11.1 ± 1.5 (IC95% 9.9-NR) versus 8.7 ± 1.3 years (IC95% 4.8-10.3), p = .006]. The better survival was only observed when AIMs diagnosis was timely associated or appeared after MDS diagnosis (p = .04). Factors associated with a better overall survival and survival without AML were steroid dependence [respectively HR = 0.042, p = .003, (IC95% 0.005-0.33) and HR = 0.07, p = .002, (IC95% 0.013-0.39)], a diagnosis of AIMs and MDS timely associated [respectively HR = 0.05, p = .009, (IC95% 0.006-0.478) and HR = 0.1, p = .008, (IC95% 0.018-0.54)] or a diagnosis of AIMs after MDS [respectively HR = 0.024, p = .009, (IC95% 0.001-0.39) and HR = 0.04, p = .008, (IC95% 0.003-0.43)]. CONCLUSION Autoimmune and inflammatory diseases associated to MDS are heterogeneous. AIMs diagnosed after or concomitantly to MDS seems associated with a better survival. Prospective studies are necessary to demonstrate that autoimmunity is associated to a better control of the MDS clone.

Abstract
SummaryA multicenter study was set up to evaluate the prevalence, clinical and biological significance of antiphosphatidylethanolamine antibodies (aPE) in thrombotic patients with or without the main known clinical and biological risk factors for thrombosis. APE and antibodies, defined as the laboratory criteria of antiphospholipid syndrome (APS) -lupus anticoagulant, anticardiolipin and anti-beta2-GPI antibodies were measured in 270 patients with thrombosis (234 venous and 37 arterial) and 236 matched controls. APE were found in 15% of thrombotic patients compared to 3% of controls (p<0.001) with no predominant isotype, no association with the main known clinical or biological risk factors for thrombosis neither with a type of thrombosis, arterial or venous. In a multivariate logistic regression analysis of antibodies, aPE showed the highest association with thrombosis (odds ratio [OR]: 4.2, p<0.001). Moreover, using a multivariate analysis in a case-control subgroup study on 158 patients, IgGaPE were found to be significantly associated with venous thrombosis (OR:6;p=0.005). Interestingly, 25 of the 40 aPE-positive patients (63%) were negative for the APS laboratory criteria. Most of them (21/25) had venous thrombosis, recurrent in ten of them. Four patients also suffered from early or late miscarriages. Our results underline the strength of the association between the presence of aPE and thrombosis and suggest their measurement in thrombotic patients, especially when lupus anticoagulant, anticardiolipin or anti-beta2-GPI antibodies are absent.

Abstract
BACKGROUND Different pulmonary hypertension (PH) mechanisms are associated with hereditary haemorrhagic telangiectasia (HHT). METHODS AND RESULTS We conducted a retrospective study of all suspected cases of PH (echocardiographically estimated systolic pulmonary artery pressure [sPAP] ≥ 40 mmHg) in patients with definite HHT recorded in the French National Reference Centre for HHT database. When right heart catheterization (RHC) was performed, PH cases were confirmed and classified among the PH groups according to the European guidelines. Among 2,598 patients in the database, 110 (4.2%) had suspected PH. Forty-seven of these 110 patients had RHC: 38/47 (81%) had a confirmed diagnosis of PH. The majority of these had isolated post-capillary PH (n = 20). We identified for the first time other haemodynamic profiles: pre-capillary pulmonary arterial hypertension (PAH) cases (n = 3) with slightly raised pulmonary vascular resistances (PVR), and combined post- and pre-capillary PH cases (n = 4). Compared to controls, survival probability was lower in patients with PAH. CONCLUSION This study revealed the diversity of PH mechanisms in HHT. The description of combined post- and pre-capillary PH with/or without high cardiac output (CO) suggests either a continuum between the pre- and post-capillary haemodynamic profiles or a different course in response to high CO.

Abstract
OBJECTIVES To assess efficacy and safety of rituximab (RTX) as induction therapy, maintenance of remission and treatment of relapses in a cohort of IgG4-related disease (IgG4-RD) patients. METHODS Nationwide retrospective multicenter study of IgG4-RD patients treated with at least one course of RTX. Clinical, biological and radiological response, relapse rate and drug tolerance were analyzed. Kaplan-Meier curves were plotted and risk factors for relapse studied with a Cox regression model. RESULTS Among 156 IgG4-RD patients included in the French database, 33 received rituximab. Clinical response was noted in 29/31 (93.5%) symptomatic patients. Glucocorticoids withdrawal was achieved in 17 (51.5%) patients. During a mean follow-up of 24.8 ±21 months, 13/31 (41.9%) responder patients relapsed after a mean delay of 19 ±11 months after RTX. Active disease, as defined by an IgG4-RD Responder Index >9 before RTX, was significantly associated with relapse (HR = 3.68, 95% CI: 1.1, 12.6) (P = 0.04), whereas maintenance therapy with systematic (i.e. before occurrence of a relapse) RTX retreatment was associated with longer relapse-free survival (41 versus 21 months; P = 0.02). Eight severe infections occurred in 4 patients during follow-up (severe infections rate of 12.1/100 patient-years) and hypogammaglobulinemia ≤5 g/l in 3 patients. CONCLUSION RTX is effective for both induction therapy and treatment of relapses in IgG4-RD, but relapses are frequent after B-cell reconstitution. Maintenance therapy with systematic RTX infusions is associated with longer relapse-free survival and might represent a novel treatment strategy. Yet, the high rate of infections and the temporary effect of RTX might be hindrances to such strategy.

Abstract
Background The disruption of endothelial homeostasis is a major determinant in the pathogenesis of systemic sclerosis (SSc) and is reflected by soluble and cellular markers of activation, injury and repair. We aimed to provide a combined assessment of endothelial markers to delineate specific profiles associated with SSc disease and its severity. Methods We conducted an observational, single-centre study comprising 45 patients with SSc and 41 healthy control subjects. Flow cytometry was used to quantify circulating endothelial microparticles (EMPs) and CD34+ progenitor cell subsets. Colony-forming unit-endothelial cells (CFU-ECs) were counted by culture assay. Circulating endothelial cells were enumerated using anti-CD146-based immunomagnetic separation. Blood levels of endothelin-1, vascular endothelial growth factor (VEGF) and soluble fractalkine (s-Fractalkine) were evaluated by enzyme-linked immunosorbent assay. Disease-associated markers were identified using univariate, correlation and multivariate analyses. Results Enhanced numbers of EMPs, CFU-ECs and non-haematopoietic CD34+CD45− endothelial progenitor cells (EPCs) were observed in patients with SSc. Patients with SSc also displayed higher serum levels of VEGF, endothelin-1 and s-Fractalkine. s-Fractalkine levels positively correlated with CD34+CD45− EPC numbers. EMPs, s-Fractalkine and endothelin-1 were independent factors associated with SSc. Patients with high CD34+CD45− EPC numbers had lower forced vital capacity values. Elevated s-Fractalkine levels were associated with disease severity, a higher frequency of pulmonary fibrosis and altered carbon monoxide diffusion. Conclusions This study identifies the mobilisation of CD34+CD45− EPCs and high levels of s-Fractalkine as specific features of SSc-associated vascular activation and disease severity. This signature may provide novel insights linking endothelial inflammation and defective repair processes in the pathogenesis of SSc.

Abstract
IgG4-related disease (IgG4-RD) is a fibro-inflammatory disorder involving virtually every organ with a risk of organ dysfunction. Despite recent studies regarding B cell and T cell compartments, the disease’s pathophysiology remains poorly understood. We examined and characterized subsets of circulating lymphocytes in untreated patients with active IgG4-RD. Twenty-eight consecutive patients with biopsy-proven IgG4-RD were included in a prospective, multicentric study. Lymphocytes’ subsets were analyzed by flow cytometry, with analysis of TH1/TH2/TH17, TFH cells, and cytokine release by peripheral blood mononuclear cells. Results were compared to healthy controls and to patients with primary Sjögren’s syndrome. Patients with IgG4-RD showed an increase of circulating T regulatory, TH2, TH17, and CD4+CXCR5+PD1+ TFH cell subsets. Accordingly, increased levels of IL-10 and IL-4 were measured in IgG-RD patients. TFH increase was characterized by the specific expansion of TFH2 (CCR6−CXCR3−), and to a lesser extent of TFH17 (CCR6+CXCR3−) cells. Interestingly, CD4+CXCR5+PD1+ TFH cells normalized under treatment. IgG4-RD is characterized by a shift of circulating T cells toward a TH2/TFH2 and TH17/TFH17 polarization. This immunological imbalance might be implicated in the disease’s pathophysiology. Treatment regimens targeting such T cells warrant further evaluation.

Abstract
IgG4-related disease (IgG4-RD) is characterized by variable tissue or organ involvements sharing common pathological findings. Orbital or orbital adnexa involvement of the disease has been reported in a few case series. The aim of our study was to characterize and analyze ophthalmic manifestations from a nationwide French case-series.Patients with IgG4-RD and orbital or orbital adnexa involvement included in the French multicentric IgG4-RD case-registry were identified. Only patients fulfilling "modified" comprehensive diagnostic criteria with pathological documentation were retained for the study. Clinical, biological, pathological, radiological findings and data regarding the response to treatment were retrospectively analyzed.According to our data registry, the frequency of IgG4-related ophthalmic disease (IgG4-ROD) was 17%. Mean age at diagnosis was 55.1 ± 7.1 years with a male/female ratio of 2.2. The 19 cases of IgG4-ROD consisted of lacrimal gland (68.4%), soft tissue (57.9%), extra-ocular muscles (36.8%), palpebral (21.1%), optical nerve (10.5%), orbital bone (10.5%), and mononeuritis (V1 and/or V2, 10.5%) involvements. IgG4-ROD was bilateral in 57.9% of cases. Extra-ophthalmic manifestations were reported in 78.9% of cases. All patients responded to prednisone but two-thirds of patients relapsed within a mean (SD) of 9.8 (3.5) months and 72.2% required long-term glucocorticoids and/or immunosuppressive agents. Eight patients were treated by rituximab with a favorable response in 87.5% of cases.Lacrimal involvement is the most frequent ophthalmic manifestation of IgG4-RD and is frequently associated with extra-orbital manifestations. Despite initial favorable response to steroids, the long-term management of relapsing patients needs to be improved.

Abstract
OBJECTIVE Cardiac involvement during systemic lupus erythematosus (SLE) may include the pericardium, myocardium, valvular tissue, and coronary arteries. The aim of this study was to describe the clinical, biological, and radiological presentation of lupus myocarditis (LM) as well as the treatment response and longterm outcomes. METHODS We conducted a multicentric retrospective study of LM from January 2000 to May 2014. RESULTS Twenty-nine patients (3 men and 26 women) fulfilled the inclusion criteria (median age at the diagnosis of SLE: 30 yrs, range 16-57). Myocarditis was the first sign of SLE in 17/29 cases (58.6%). Troponin was elevated in 20/25 cases. Electrocardiogram results were abnormal in 25/28 cases. Echocardiography revealed low (≤ 45%) left ventricular ejection fraction (LVEF; 19/29, 66%) and pericardium effusion (20/29, 69%). Cardiac magnetic resonance imaging revealed delayed gadolinium enhancement in 9/13 patients (69%). Patients were treated with corticosteroids (n = 28), cyclophosphamide (CYC; n = 16), intravenous immunoglobulins (n = 8), and/or mycophenolate mofetil (n = 2). The median followup was 37 months. One month after the beginning of the treatment, 10/23 patients (43%) who had undergone echocardiography had an LVEF ≥ 55%. At the end of followup, 21/26 patients (81%) exhibited an LVEF ≥ 55%. Three patients died during followup, and 2 died from LM. CONCLUSION LM is a severe manifestation of SLE. It can be the first manifestation of the disease or it can occur during followup, in particular in untreated patients. However, the longterm prognosis is typically positive. Patients with less severe disease exhibited good LVEF recovery without CYC.

Abstract
Immune thrombocytopenic purpura (ITP) is a disease characterized by antibody-mediated platelet destruction. The T- and B-cell subsets have been extensively studied in primary ITP, but the NK cell compartment has been less thoroughly explored. We investigated the NK cell receptor repertoire and the functionality of NK cells in the peripheral blood and spleen in patients with primary ITP. An immunophenotypic analysis of peripheral blood lymphocytes from patients revealed that the numbers of CD19+ B lymphocytes, CD4+ and CD8+ T lymphocytes and CD3-CD56+ NK cells were within the normal range. No major alteration to the expression of distinct inhibitory or activating NK cell receptors was observed. The functionality of NK cells, as evaluated by their ability to degranulate in conditions of natural cytotoxicity or antibody-dependent cell cytotoxicity (ADCC), was preserved in these patients. By contrast, these stimuli induced lower levels of IFNγ production by the NK cells of ITP patients than by those of healthy controls. We then compared the splenic NK cell functions of ITP patients with those of cadaveric heart-beating donors (CHBD) as controls. The splenic NK cells of ITP patients tended to be less efficient in natural cytotoxicity conditions and more efficient in ADCC conditions than control splenic NK cells. Finally, we found that infusions of intravenous immunoglobulin led to the inhibition of NK cell activation through the modulation of the interface between target cells and NK cells.
