RESUMO

OBJECTIVE: In patients with SSc, peripheral vasculopathy can promote critical ischaemia and gangrene. The aim of this study was to investigate the prevalence, incidence and risk factors for gangrene in the EUSTAR cohort. METHODS: We included patients from the EUSTAR database fulfilling the ACR 1980 or the ACR/EULAR 2013 classification criteria for SSc, with at least one visit recording data on gangrene. Centres were asked for supplementary data on traditional cardiovascular risk factors. We analysed the cross-sectional relationship between gangrene and its potential risk factors by univariable and multivariable logistic regression. Longitudinal data were analysed by Cox proportional hazards regression. RESULTS: 1757 patients were analysed (age 55.9 [14.5] years, disease duration 7.9 [10.3] years, male sex 16.7%, 24.6% diffuse cutaneous subset [dcSSc]). At inclusion, 8.9% of patients had current or previous digital gangrene, 16.1% had current digital ulcers (DUs) and 42.7% had ever had DUs (current or previous). Older age, DUs ever and dcSSc were statistically significant risk factors for gangrene in the cross-sectional multivariable model. During a median follow-up of 13.1 months, 16/771 (0.9%) patients developed gangrene. All 16 patients who developed gangrene had previously had DUs and gangrene. Further risk factors for incident gangrene were the dcSSc subset and longer disease duration. CONCLUSION: In unselected SSc patients, gangrene occurs in about 9% of SSc patients. DUs ever and, to a lesser extent, the dcSSc subset are strongly and independently associated with gangrene, while traditional cardiovascular risk factors could not be identified as risk factors.

RESUMO

OBJECTIVES: Limited cutaneous systemic sclerosis (LcSSc) is the most common subset of SSc but it has been overlooked in the past years. At a time at which clinical trials focus on diffuse cutaneous SSc (DcSSc) we aimed at clarifying the outcomes of LcSSc and at evaluating whether potential drug positioned in DcSSc may also be used in LcSSc. METHODS: The EUSTAR database was used to investigate skin, lung and peripheral vasculopathy outcomes in LcSSc. Worsening of skin fibrosis, ILD and peripheral vasculopathy were defined by an increase in modified Rodnan skin score (mRSS) > 3.5 points, a decrease of FVC > 10% in patients with ILD at baseline, and by the development of new digital ulcers (DU) in patients without DU at baseline. RESULTS: 8013 LcSSc and 4786 DcSSc patients were included. In contrast to DcSSc, skin disease was remarkably stable in the majority of LcSSc patients with >80% having a change lower than ±4 units of mRSS at 12, 24 and 36 months follow-up. Conversely, FVC changes over time were very similar between LcSSc and DcSSc. Regarding DU, numbers of patients with new DU over time seemed to be almost similar between the two subsets. CONCLUSIONS: LcSSc patients have a low mRSS at baseline with marginal changes with time. Conversely, SSc-ILD can be as progressive as in DcSSc supporting the inclusion of LcSSc patients in SSc-ILD trials and suggesting potential benefit of any anti-ILD drugs. Similarly, although slightly less common, DU should receive the same attention in the two subsets.

RESUMO

Chronic inflammation and fibrosis can result from inappropriately activated immune responses that are mediated by macrophages. Macrophages can acquire memory-like characteristics in response to antigen exposure. Here, we show the effect of BCG or low-dose LPS stimulation on macrophage phenotype, cytokine production, chromatin and metabolic modifications. Low-dose LPS training alleviates fibrosis and inflammation in a mouse model of systemic sclerosis (SSc), whereas BCG-training exacerbates disease in this model. Adoptive transfer of low-dose LPS-trained or BCG-trained macrophages also has beneficial or harmful effects, respectively. Furthermore, coculture with low-dose LPS trained macrophages reduces the fibro-inflammatory profile of fibroblasts from mice and patients with SSc, indicating that trained immunity might be a phenomenon that can be targeted to treat SSc and other autoimmune and inflammatory fibrotic disorders.

RESUMO

Systemic sclerosis (SSc) is an autoimmune disease that shows one of the highest mortality rates among rheumatic diseases. We perform a large genome-wide association study (GWAS), and meta-analysis with previous GWASs, in 26,679 individuals and identify 27 independent genome-wide associated signals, including 13 new risk loci. The novel associations nearly double the number of genome-wide hits reported for SSc thus far. We define 95% credible sets of less than 5 likely causal variants in 12 loci. Additionally, we identify specific SSc subtype-associated signals. Functional analysis of high-priority variants shows the potential function of SSc signals, with the identification of 43 robust target genes through HiChIP. Our results point towards molecular pathways potentially involved in vasculopathy and fibrosis, two main hallmarks in SSc, and highlight the spectrum of critical cell types for the disease. This work supports a better understanding of the genetic basis of SSc and provides directions for future functional experiments.

RESUMO

OBJECTIVES: Racial factors play a significant role in SSc. We evaluated differences in SSc presentations between white patients (WP), Asian patients (AP) and black patients (BP) and analysed the effects of geographical locations. METHODS: SSc characteristics of patients from the EUSTAR cohort were cross-sectionally compared across racial groups using survival and multiple logistic regression analyses. RESULTS: The study included 9162 WP, 341 AP and 181 BP. AP developed the first non-RP feature faster than WP but slower than BP. AP were less frequently anti-centromere (ACA; odds ratio (OR) = 0.4, P < 0.001) and more frequently anti-topoisomerase-I autoantibodies (ATA) positive (OR = 1.2, P = 0.068), while BP were less likely to be ACA and ATA positive than were WP [OR(ACA) = 0.3, P < 0.001; OR(ATA) = 0.5, P = 0.020]. AP had less often (OR = 0.7, P = 0.06) and BP more often (OR = 2.7, P < 0.001) diffuse skin involvement than had WP. AP and BP were more likely to have pulmonary hypertension [OR(AP) = 2.6, P < 0.001; OR(BP) = 2.7, P = 0.03 vs WP] and a reduced forced vital capacity [OR(AP) = 2.5, P < 0.001; OR(BP) = 2.4, P < 0.004] than were WP. AP more often had an impaired diffusing capacity of the lung than had BP and WP [OR(AP vs BP) = 1.9, P = 0.038; OR(AP vs WP) = 2.4, P < 0.001]. After RP onset, AP and BP had a higher hazard to die than had WP [hazard ratio (HR) (AP) = 1.6, P = 0.011; HR(BP) = 2.1, P < 0.001]. CONCLUSION: Compared with WP, and mostly independent of geographical location, AP have a faster and earlier disease onset with high prevalences of ATA, pulmonary hypertension and forced vital capacity impairment and higher mortality. BP had the fastest disease onset, a high prevalence of diffuse skin involvement and nominally the highest mortality.

RESUMO

Systemic sclerosis (SSc) is a connective tissue disease characterized by diffuse microangiopathy and immune dysregulation which ultimately result in widespread fibrosis of skin and internal organs. Although the 2013 EULAR/ACR criteria have allowed to improve the sensitivity for SSc diagnosis, it has recently come to light that the traditional subclassification into limited and diffuse cutaneous forms does not appear to fully capture the different phenotypes of the scleroderma spectrum. In this regard, a recent large cluster analysis-based study and other ongoing projects are trying to achieve a better stratification of SSc patients, as the disease course remains largely unpredictable to date. Recent preclinical studies and randomized controlled trials have yielded encouraging results with new drugs targeting inflammatory/immunological and fibrotic pathways. One of the main unmet needs in SSc remains the early identification of patients at high mortality risk, for whom aggressiveness of therapies ought to be determined and weighed against disease prognosis. Furthermore, lung and cardiac transplantation may also be taken into account in some carefully selected patients. Though the prognosis of SSc remains poor, an optimized stratification of patients along with the recent and ongoing advances in therapies could greatly impact the natural course of the disease in the near future. Moreover, it is envisioned that there will be an increasing need in the future to further develop combination therapies to better fight against this complex disease. In this review we discussed new insights into organ involvements and therapeutic options.

RESUMO

Systemic sclerosis primarily affects women. This sex bias raises the question on the role female hormones could play in the development of fibrosis, which is largely unknown. Our aim was to evaluate the effects of estrogens in the development of experimental dermal fibrosis, in the mouse models of bleomycin-induced dermal fibrosis and tight skin (Tsk-1) mice, and on the activation of dermal fibroblasts by transforming growth factor-ß (TGF-ß). Estrogen inhibition, obtained through gene inactivation for the estrogen receptor-αknockout or treatment with tamoxifen, exacerbated skin fibrosis in the bleomycin model and in the Tsk-1 mice. In the dermal fibroblasts, treatment with 17-ß-estradiol significantly decreased the stimulatory effects of TGF-ß on collagen synthesis and myofibroblast differentiation, decreased the activation of canonical TGF-ß signaling, and markedly reduced the expression of the TGF-ß target genes. Tamoxifen reversed the inhibitory effects of estrogens by restoring Smad2/3 phosphorylation and TGF-ß-induced collagen synthesis. Our results demonstrate a beneficial effect of estrogens in dermal fibrosis. Estrogens reduce the TGF-ß-dependent activation of dermal fibroblasts, and estrogen inhibition leads to a more severe experimental dermal fibrosis. These findings are consistent with the prominent development of systemic sclerosis in postmenopausal women and the greater severity of the disease in men.

RESUMO

OBJECTIVES: To investigate the influence of vasodilator drugs on the occurrence of features depending on myocardial ischaemia/fibrosis (ventricular arrhythmias, Q waves, cardiac blocks, pacemaker implantation, left ventricular ejection fraction (LVEF) <55%, and/or congestive heart failure and sudden cardiac death) in systemic sclerosis (SSc). METHODS: 601 patients with SSc were enrolled from 1 December 2012 to 30 November 2015 and had a second visit 0.5-4 years apart. 153 received no vasodilators; 448 received vasodilator therapy (ie, calcium channel blockers and/or ACE inhibitors or angiotensin II receptor blockers or combinations of them), 89 of them being also treated with either endothelin receptor antagonists or PDE5 inhibitors or prostanoids. Associations between the occurrence of myocardial disease manifestations and any demographic, disease and therapeutic aspect were investigated by Cox regression analysis. A Cox frailty survival model with centre of enrolment as random effect was performed. RESULTS: During 914 follow-up patient-years, 12 ventricular arrhythmias, 5 Q waves, 40 cardiac blocks, 6 pacemaker implantations and 19 reduced LVEF and/or congestive heart failure (CHF) occurred. In multivariate Cox regression analysis, vasodilator therapy was associated with a lower incidence of ventricular arrhythmias (p=0.03); low-dose acetylsalicylic acid (ASA) with a lower incidence of cardiac blocks and/or Q waves and/or pacemaker implantation (p=0.02); active disease with a higher incidence of LVEF <55% and/or CHF and cardiac blocks and/or Q waves and/or pacemaker implantation (p=0.05). CONCLUSIONS: The present study might suggest a preventative effect on the occurrence of distinct myocardial manifestations by vasodilator therapy and low-dose ASA.

RESUMO

BACKGROUND: The European Scleroderma Trials and Research Group (EUSTAR) recently developed a preliminarily revised activity index (AI) that performed better than the European Scleroderma Study Group Activity Index (EScSG-AI) in systemic sclerosis (SSc). OBJECTIVE: To assess the predictive value for short-term disease severity accrual of the EUSTAR-AI, as compared with those of the EScSG-AI and of known adverse prognostic factors. METHODS: Patients with SSc from the EUSTAR database with a disease duration from the onset of the first non-Raynaud sign/symptom ≤5 years and a baseline visit between 2003 and 2014 were first extracted. To capture the disease activity variations over time, EUSTAR-AI and EScSG-AI adjusted means were calculated. The primary outcome was disease progression defined as a Δ≥1 in the Medsger's severity score and in distinct items at the 2-year follow-up visit. Logistic regression analysis was carried out to identify predictive factors. RESULTS: 549 patients were enrolled. At multivariate analysis, the EUSTAR-AI adjusted mean was the only predictor of any severity accrual and of that of lung and heart, skin and peripheral vascular disease over 2 years. CONCLUSION: The adjusted mean EUSTAR-AI has the best predictive value for disease progression and development of severe organ involvement over time in SSc.

RESUMO

OBJECTIVE: T cells play a key role in the pathogenesis of early systemic sclerosis. This study was undertaken to assess the safety and efficacy of abatacept in patients with diffuse cutaneous systemic sclerosis (dcSSc). METHODS: In this 12-month, randomized, double-blind, placebo-controlled trial, participants were randomized 1:1 to receive either subcutaneous abatacept 125 mg or matching placebo, stratified by duration of dcSSc. Escape therapy was allowed at 6 months for worsening disease. The coprimary end points were change in the modified Rodnan skin thickness score (MRSS) compared to baseline and safety over 12 months. Differences in longitudinal outcomes were assessed according to treatment using linear mixed models, with outcomes censored after initiation of escape therapy. Skin tissue obtained from participants at baseline was classified into intrinsic gene expression subsets. RESULTS: Among 88 participants, the adjusted mean change in the MRSS at 12 months was -6.24 units for those receiving abatacept and -4.49 units for those receiving placebo, with an adjusted mean treatment difference of -1.75 units (P = 0.28). Outcomes for 2 secondary measures (Health Assessment Questionnaire disability index and a composite measure) were clinically and statistically significantly better with abatacept. The proportion of subjects in whom escape therapy was needed was higher in the placebo group relative to the abatacept group (36% versus 16%). In the inflammatory and normal-like skin gene expression subsets, decline in the MRSS over 12 months was clinically and significantly greater in the abatacept group versus the placebo group (P < 0.001 and P = 0.03, respectively). In the abatacept group, adverse events occurred in 35 participants versus 40 participants in the placebo group, including 2 deaths and 1 death, respectively. CONCLUSION: In this phase II trial, abatacept was well-tolerated, but change in the MRSS was not statistically significant. Secondary outcome measures, including gene expression subsets, showed evidence in support of abatacept. These data should be confirmed in a phase III trial.

RESUMO

The interleukin (IL)-1 family of cytokines is strongly associated with systemic sclerosis (SSc) and pulmonary involvement, but the molecular mechanisms are poorly understood. The aim of this study was to assess the role of IL-1α and IL-1ß in pulmonary vascular and interstitial remodelling in a mouse model of SSc.IL-1α and IL-1ß were localised in lungs of SSc patients and in the fos-related antigen-2 (Fra-2) transgenic (TG) mouse model of SSc. Lung function, haemodynamic parameters and pulmonary inflammation were measured in Fra-2 TG mice with or without 8 weeks of treatment with the IL-1 receptor antagonist anakinra (25 mg·kg-1·day-1). Direct effects of IL-1 on pulmonary arterial smooth muscle cells (PASMCs) and parenchymal fibroblasts were investigated in vitroFra-2 TG mice exhibited increased collagen deposition in the lung, restrictive lung function and enhanced muscularisation of the vasculature with concomitant pulmonary hypertension reminiscent of the changes in SSc patients. Immunoreactivity of IL-1α and IL-1ß was increased in Fra-2 TG mice and in patients with SSc. IL-1 stimulation reduced collagen expression in PASMCs and parenchymal fibroblasts via distinct signalling pathways. Blocking IL-1 signalling in Fra-2 TG worsened pulmonary fibrosis and restriction, enhanced T-helper cell type 2 (Th2) inflammation, and increased the number of pro-fibrotic, alternatively activated macrophages.Our data suggest that blocking IL-1 signalling as currently investigated in several clinical studies might aggravate pulmonary fibrosis in specific patient subsets due to Th2 skewing of immune responses and formation of alternatively activated pro-fibrogenic macrophages.

RESUMO

OBJECTIVES: Mortality and worsening of organ function are desirable endpoints for clinical trials in systemic sclerosis (SSc). The aim of this study was to identify factors that allow enrichment of patients with these endpoints, in a population of patients from the European Scleroderma Trials and Research group database. METHODS: Inclusion criteria were diagnosis of diffuse SSc and follow-up over 12±3 months. Disease worsening/organ progression was fulfilled if any of the following events occurred: new renal crisis; decrease of lung or heart function; new echocardiography-suspected pulmonary hypertension or death. In total, 42 clinical parameters were chosen as predictors for the analysis by using (1) imputation of missing data on the basis of multivariate imputation and (2) least absolute shrinkage and selection operator regression. RESULTS: Of 1451 patients meeting the inclusion criteria, 706 had complete data on outcome parameters and were included in the analysis. Of the 42 outcome predictors, eight remained in the final regression model. There was substantial evidence for a strong association between disease progression and age, active digital ulcer (DU), lung fibrosis, muscle weakness and elevated C-reactive protein (CRP) level. Active DU, CRP elevation, lung fibrosis and muscle weakness were also associated with a significantly shorter time to disease progression. A bootstrap validation step with 10 000 repetitions successfully validated the model. CONCLUSIONS: The use of the predictive factors presented here could enable cohort enrichment with patients at risk for overall disease worsening in SSc clinical trials.

RESUMO

OBJECTIVE: To evaluate agreement of the updated European League Against Rheumatism and European Scleroderma Trials and Research group (EUSTAR) recommendations for treatment of systemic sclerosis (SSc) among international experts. In addition, to determine factors that might influence agreement. METHODS: Level of agreement (10-point scale: 0 = not at all, 10 = completely agree) and local drug availability (yes/no) were assessed using an online survey. The Web link to the survey was shared with 481 unique e-mail addresses and SSc networks (Scleroderma Clinical Trials Consortium, Australian Scleroderma Interest Group, International Systemic Sclerosis Inception Cohort). Level of agreement was compared between subgroups stratified for participant characteristics. RESULTS: In total, 263 experts participated, of whom n = 209 (79%) completed each single item. The majority were rheumatologists (n = 200, 76%) working in Europe (n = 185; 71%); 59% (n = 156) were EUSTAR members; and 57% (n = 151) had > 10 years of clinical experience. Overall level of agreement was high (mean 8.0, SD 2.5). The 3 highest mean agreements included (1) angiotensin-converting enzyme inhibitors for scleroderma renal crisis (9.2, SD 2.1); (2) blood pressure control in SSc-patients treated with corticosteroids (9.0, SD 2.2); (3) proton pump inhibitors to prevent reflux complications (9.0, SD 2.2). The 3 lowest mean agreements included (1) fluoxetine for Raynaud phenomenon (RP; 4.6, SD 2.8); (2) hematopoietic stem cell transplantation (HSCT) for severe SSc (7.1, SD 2.9); (3) phosphodiesterase inhibitors 5 for RP (7.3, SD 2.7). Agreement differed between Europe and non-Europe for the use of iloprost, bosentan, methotrexate, HSCT, and cyclophosphamide. Treatment availability could partially explain differential agreement for iloprost, bosentan, and HSCT. CONCLUSION: In general, worldwide expert agreement on updated recommendations for treatment of SSc is high, supporting their value. Differences in agreement are partially explained by geographical area and treatment availability.

RESUMO

BACKGROUND: Sandoz etanercept (SDZ ETN; GP2015) is an etanercept biosimilar with equivalent efficacy and comparable safety and immunogenicity to reference etanercept (ETN) in patients with moderate-to-severe chronic plaque-type psoriasis. METHODS: EQUIRA was a phase III, double-blind study conducted in patients with moderate-to-severe rheumatoid arthritis and inadequate response to disease-modifying anti-rheumatic drugs. Eligible patients were randomized 1:1 to receive subcutaneous 50 mg SDZ ETN or ETN, once-weekly, for 24 weeks. At week 24, patients with at least moderate EULAR response in the SDZ ETN group continued SDZ ETN treatment, and those in the ETN group were switched to receive 50 mg SDZ ETN, for up to 48 weeks. Patients received concomitant methotrexate at a stable dose (10-25 mg/week) and folic acid (≥ 5 mg/week). Equivalence between SDZ ETN and ETN for change from baseline in disease activity score including 28 joint count C-reactive protein (DAS28-CRP) at week 24 (primary endpoint) and comparable safety and immunogenicity profile of SDZ ETN and ETN have previously been demonstrated at week 24. Herein, we present the 48-week results of the study after a single switch from ETN to its biosimilar at week 24. RESULTS: The least squares mean (standard error) change in DAS28-CRP from baseline up to week 48 was comparable between "continued SDZ ETN" (- 2.90 [0.12], n = 148) and "switched to SDZ ETN" (- 2.78 [0.13], n = 131) groups. The proportion of patients achieving EULAR good/moderate responses based on DAS28-erythrocyte sedimentation rate and ACR20/50/70 response rates were comparable between the two groups. The proportion of patients with at least one treatment-emergent adverse event was 42.9% in the "continued SDZ ETN" and 38.0% in the "switched to SDZ ETN" groups. Serious adverse events occurred in 4 patients in each of the two groups. After week 24, none of the patients in the switched group developed anti-drug antibodies (ADAs), while 4 patients in the continued SDZ ETN group had single-event, very low titer, non-neutralizing ADAs detected. CONCLUSIONS: The 48-week results from the EQUIRA study demonstrate that switch from ETN to SDZ ETN in patients with moderate-to-severe rheumatoid arthritis does not impact the efficacy, safety, or immunogenicity of etanercept.

RESUMO

Background: Systemic sclerosis (SSc) is a severe, progressive multiorgan disease but to date, there are no established standardised international guidelines for follow-up of patients with SSc. The goal of this project was to develop an expert consensus for annual systematic investigations in patients with SSc to enhance their standard-of-care. Material and methods: The Delphi method was applied. All SSc experts from the European Scleroderma Trials and Research group network and the Scleroderma Clinical Trial Consortium were invited to participate. All experts were asked to answer questionnaires in five Delphi steps to determine the domains of interest and tools for each domain for an annual systematic assessment of patients with SSc. Each item was rated on a scale between 0% and 100% (not and very important), and parameters rated >80% by more than 75% of the experts were regarded as acceptable. Results: In total, 157 experts worldwide participated with 71.3% experts seeing >50 patients with SSc annually. In the first round, 23 domains and 204 tools were suggested. After five Delphi steps, experts agreed on 10 domains including (1) Raynaud's phenomenon; (2) Digital ulcers; (3) Skin and mucosa; (4) Lung; (5); Heart; (6) GI domain, (7) Renal; (8) Musculoskeletal; (9) Laboratory and (10) Treatment. Overall, 55 tools were identified including clinical assessments, laboratory measurements and imaging or functional investigations. Conclusion: Through five Delphi steps with world leading experts, a consensus was established on strongly suggested tools for a minimum annual systemic assessment of organ involvement in SSc. This work should enhance the standardisation and homogenisation of the practices.

RESUMO

The Raynaud's condition score is a 11-point scale severity score used in Raynaud's phenomenon clinical trials since 1998. The Raynaud's condition score diary has been recommended for use in clinical trials assessing efficacy of interventions on scleroderma related Raynaud's phenomenon. However, this score has never been formally validated in French. We thus performed a translation and a linguistic validation of the Raynaud's condition score through a forward/backward translations process followed by an expert review and cognitive patient interviews. The translations led to a French version of the Raynaud's condition score that was linguistically valid, and conceptually equivalent to the original English version. This "Score de Raynaud" will be usable to perform and harmonize clinical trials in French-speaking patients with secondary Raynaud's phenomenon.

RESUMO

OBJECTIVE: Systemic sclerosis (SSc) is a heterogeneous connective tissue disease that is typically subdivided into limited cutaneous SSc (lcSSc) and diffuse cutaneous SSc (dcSSc) depending on the extent of skin involvement. This subclassification may not capture the entire variability of clinical phenotypes. The European Scleroderma Trials and Research (EUSTAR) database includes data on a prospective cohort of SSc patients from 122 European referral centers. This study was undertaken to perform a cluster analysis of EUSTAR data to distinguish and characterize homogeneous phenotypes without any a priori assumptions, and to examine survival among the clusters obtained. METHODS: A total of 11,318 patients were registered in the EUSTAR database, and 6,927 were included in the study. Twenty-four clinical and serologic variables were used for clustering. RESULTS: Clustering analyses provided a first delineation of 2 clusters showing moderate stability. In an exploratory attempt, we further characterized 6 homogeneous groups that differed with regard to their clinical features, autoantibody profile, and mortality. Some groups resembled usual dcSSc or lcSSc prototypes, but others exhibited unique features, such as a majority of lcSSc patients with a high rate of visceral damage and antitopoisomerase antibodies. Prognosis varied among groups and the presence of organ damage markedly impacted survival regardless of cutaneous involvement. CONCLUSION: Our findings suggest that restricting subsets of SSc patients to only those based on cutaneous involvement may not capture the complete heterogeneity of the disease. Organ damage and antibody profile should be taken into consideration when individuating homogeneous groups of patients with a distinct prognosis.

RESUMO

OBJECTIVE: To assess the safety and efficacy of rituximab in systemic sclerosis (SSc) in clinical practice. METHODS: We performed a prospective study including patients with SSc from the European Scleroderma Trials and Research (EUSTAR) network treated with rituximab and matched with untreated patients with SSc. The main outcomes measures were adverse events, skin fibrosis improvement, lung fibrosis worsening and steroids use among propensity score-matched patients treated or not with rituximab. RESULTS: 254 patients were treated with rituximab, in 58% for lung and in 32% for skin involvement. After a median follow-up of 2 years, about 70% of the patients had no side effect. Comparison of treated patients with 9575 propensity-score matched patients showed that patients treated with rituximab were more likely to have skin fibrosis improvement (22.7 vs 14.03 events per 100 person-years; OR: 2.79 [1.47-5.32]; p=0.002). Treated patients did not have significantly different rates of decrease in forced vital capacity (FVC)>10% (OR: 1.03 [0.55-1.94]; p=0.93) nor in carbon monoxide diffusing capacity (DLCO) decrease. Patients having received rituximab were more prone to stop or decrease steroids (OR: 2.34 [1.56-3.53], p<0.0001). Patients treated concomitantly with mycophenolate mofetil had a trend for better outcomes as compared with patients receiving rituximab alone (delta FVC: 5.22 [0.83-9.62]; p=0.019 as compared with controls vs 3 [0.66-5.35]; p=0.012). CONCLUSION: Rituximab use was associated with a good safety profile in this large SSc-cohort. Significant change was observed on skin fibrosis, but not on lung. However, the limitation is the observational design. The potential stabilisation of lung fibrosis by rituximab has to be addressed by a randomised trial.
