Abstract

BACKGROUND: Enrichment strategies from clinical trials for progressive systemic sclerosis-associated interstitial lung disease (SSc-ILD) have not been tested in a real-life cohort.RESEARCH QUESTION: Do enrichment strategies for progressive ILD impact efficacy, repre-sentativeness, and feasibility in patients with SSc-ILD from the European Scleroderma Trials and Research (EUSTAR) database?STUDY DESIGN AND METHODS: We applied the inclusion criteria of major recent SSc-ILD trials (Study of the Efficacy and Safety of Tocilizumab in Participants With Systemic Sclerosis [focuSSced], Scleroderma Lung Study II [SLS II], and Safety and Efficacy of Nintedanib in Systemic Sclerosis [SENSCIS]) and assessed progressive ILD, which was defined as absolute change in FVC and as significant progression (FVC decline $10%). Data were compared with all patients and with patients who did not fulfill any inclusion criteria. RESULTS: In total, 2,258 patients with SSc-ILD were included: 31.2% of the patients met SENSCIS criteria; 5.8% of the patients met SLS II criteria; 1.6% of the patients met focuSSced criteria, and 67.7% (1,529) of the patients did not meet any criteria. In the first 12 + 3 months, the absolute FVC decline in all patients and in patients who fulfilled criteria from SENSCIS was -0.1%, in patients who fulfilled criteria from focuSSced was -3.7%, and in patients who fulfilled criteria from SLS II was 2.3%, with accompanying more progressors in focuSSced. The patient populations that fulfilled the different study inclusion criteria significantly differed in various clinical parameters. In the second 12-month period, SENSCIS-enriched patients had a further absolute FVC% decline as described for the total cohort. In contrast, patients who fulfilled the focuSSced and SLS II criteria showed numeric improvement of lung function. There were no significant associations of enrichment criteria and ILD progression.INTERPRETATION: The application of enrichment criteria from previous clinical trials showed enrichment for progression with variable success, which led to selected patient populations reducing feasibility of recruitment. These findings are important for future clinical trial design and interpretation of the results of published trials.CHEST 2023; 163(3):586-598

Abstract

ObjectiveTo assess the safety and efficacy of rituximab in systemic sclerosis (SSc) in clinical practice.MethodsWe 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.Results254 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], pConclusionRituximab 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.

Abstract

Objective To identify nailfold videocapillaroscopic features and other clinical risk factors for new digital ulcers (DUs) during a 6-month period in patients with systemic sclerosis (SSc). Methods In this multicenter, prospective, observational cohort study, the videoCAPillaroscopy (CAP) study, we evaluated 623 patients with SSc from 59 centers (14 countries). Patients were stratified into 2 groups: a DU history group and a no DU history group. At enrollment, patients underwent detailed nailfold videocapillaroscopic evaluation and assessment of demographic characteristics, DU status, and clinical and SSc characteristics. Risk factors for developing new DUs were assessed using univariable and multivariable logistic regression (MLR) analyses. Results Of the 468 patients in the DU history group (mean ± SD age 54.0 ± 13.7 years), 79.5% were female, 59.8% had limited cutaneous SSc, and 22% developed a new DU during follow-up. The strongest risk factors for new DUs identified by MLR in the DU history group included the mean number of capillaries per millimeter in the middle finger of the dominant hand, the number of DUs (categorized as 0, 1, 2, or ≥3), and the presence of critical digital ischemia. The receiver operating characteristic (ROC) of the area under the curve (AUC) of the final MLR model was 0.738 (95% confidence interval [95% CI] 0.681–0.795). Internal validation through bootstrap generated a ROC AUC of 0.633 (95% CI 0.510–0.756). Conclusion This international prospective study, which included detailed nailfold videocapillaroscopic evaluation and extensive clinical characterization of patients with SSc, identified the mean number of capillaries per millimeter in the middle finger of the dominant hand, the number of DUs at enrollment, and the presence of critical digital ischemia at enrollment as risk factors for the development of new DUs.

Abstract

The aim of this study was to assess nailfold capillaroscopic (NC) findings in patients with primary Sjogren's syndrome (PSS) with and without Raynaud's phenomenon (RP) as well as in the presence of positive anti-SSA/Ro and anti-SSB/La antibodies. Videocapillaroscopy was performed in 150 patients with PSS. Data collected included demographics, presence of RP, PSS symptoms, antinuclear antibodies, rheumatoid factor, anti-Ro, anti-La, anti-CCP, salivary scintigraphy, labial biopsy, and NC findings. RP was present in 32 % of PSS, keratoconjunctivitis sicca in 91 %, oral xerosis in 93 %, and skin or genital xerosis in 53 %. In patients with positive anti-SSA/Ro (75 %) and positive anti-SSB/La (40 %), NC showed normal findings in 53 % of cases and nonspecific in 36 %. In patients with PSS, NC was normal in 51 % of cases and non-specific in 34 %. Scleroderma pattern was found in 14 patients. RP associated with PSS had non-specific capillaroscopy in 40 % of cases (p = 0.1). Pericapillary haemorrhages (p = 0.06) and capillary thrombosis (p = 0.2) were not increased, but more dilated capillaries were detected in 48 % of cases. Patients with positive anti-Ro and/or anti-La have not a distinct NC profile. Patients with RP associated with PSS had more dilated capillaries, but neither pericapillary haemorrhages nor capillary thrombosis was observed.

Abstract

Item does not contain fulltext Systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are two archetypal systemic autoimmune diseases which have been shown to share multiple genetic susceptibility loci. In order to gain insight into the genetic basis of these diseases, we performed a pan-meta-analysis of two genome-wide association studies (GWASs) together with a replication stage including additional SSc and SLE cohorts. This increased the sample size to a total of 21 109 (6835 cases and 14 274 controls). We selected for replication 19 SNPs from the GWAS data. We were able to validate KIAA0319L (P = 3.31 x 10(-11), OR = 1.49) as novel susceptibility loci for SSc and SLE. Furthermore, we also determined that the previously described SLE susceptibility loci PXK (P = 3.27 x 10(-11), OR = 1.20) and JAZF1 (P = 1.11 x 10(-8), OR = 1.13) are shared with SSc. Supporting these new discoveries, we observed that KIAA0319L was overexpressed in peripheral blood cells of SSc and SLE patients compared with healthy controls. With these, we add three (KIAA0319L, PXK and JAZF1) and one (KIAA0319L) new susceptibility loci for SSc and SLE, respectively, increasing significantly the knowledge of the genetic basis of autoimmunity.

Abstract

Contains fulltext : 109760.pdf (Publisher’s version ) (Closed access) Regulatory T cells (T(regs)) are crucial in the maintenance of the immune tolerance and seem to have an important role in systemic sclerosis (SSc). The interleukin 2 receptor alpha (IL2RA) is an important T(reg) marker, and polymorphisms of IL2RA gene are associated with a number of autoimmune diseases. Therefore, we aimed to investigate for the first time the association of the IL2RA locus in SSc. For this purpose, a total of 3023 SSc patients and 2735 matched healthy controls, from six European Caucasian cohorts, were genotyped for the IL2RA gene variants rs11594656, rs2104286 and rs12722495 using the TaqMan allelic discrimination technology. The overall meta-analysis reached statistical significance when the three polymorphisms were tested for association with SSc, the limited subtype (lcSSc) and anti-centromere auto-antibodies (ACAs). However, no significant P-values were obtained when the ACA-positive patients were removed from the SSc and lcSSc groups, suggesting that these associations rely on ACA positivity. The strongest association signal with ACA production was detected for rs2104286 (P(FDR)=2.07 x 10(-4), odds ratio=1.30 (1.14-1.47)). The associations of rs11594656 and rs12722495 were lost after conditioning to rs2104286, and allelic combination tests did not evidence a combined effect, indicating that rs2104286 best described the association between IL2RA and ACA presence in SSc. 01 februari 2012

Abstract

A single-nucleotide polymorphism (SNP) at the IL12RB2 locus showed a suggestive association signal in a previously published genome-wide association study (GWAS) in systemic sclerosis (SSc). Aiming to reveal the possible implication of the IL12RB2 gene in SSc, we conducted a follow-up study of this locus in different Caucasian cohorts. We analyzed 10 GWAS-genotyped SNPs in the IL12RB2 region (2309 SSc patients and 5161 controls). We then selected three SNPs (rs3790567, rs3790566 and rs924080) based on their significance level in the GWAS, for follow-up in an independent European cohort comprising 3344 SSc and 3848 controls. The most-associated SNP (rs3790567) was further tested in an independent cohort comprising 597 SSc patients and 1139 controls from the USA. After conditional logistic regression analysis of the GWAS data, we selected rs3790567 [PMH5 1.92 3 10 -5 odds ratio (OR) 5 1.19] as the genetic variant with the firmest independent association observed in the analyzedGWASpeak of association. After the first follow-up phase, only the association of rs3790567 was consistent (PMH5 4.84 3 10 -3OR 5 1.12). The second follow-up phase confirmed this finding (Px2 5 2.82 3 10 -4 OR 5 1.34). After performing overall pooled-analysis of all the cohorts included in the present study, the association found for the rs3790567 SNP in the IL12RB2 gene region reached GWAS-level significant association (PMH5 2.82 3 10 -9 OR 5 1.17). Our data clearly support the IL12RB2 genetic association with SSc, and suggest a relevant role of the interleukin 12 signaling pathway in SSc pathogenesis. © The Author 2011.

Abstract

Introduction Potassium voltage-gated channel shaker-related subfamily member 5 (KCNA5) is implicated in vascular tone regulation, and its inhibition during hypoxia produces pulmonary vasoconstriction. Recently, a protective association of the KCNA5 locus with systemic sclerosis (SSc) patients with pulmonary arterial hypertension (PAH) was reported. Hence, the aim of this study was to replicate these findings in an independent multicenter Caucasian SSc cohort. Methods The 2,343 SSc cases (179 PAH positive, confirmed by right-heart catheterization) and 2,690 matched healthy controls from five European countries were included in this study. Rs10744676 single-nucleotide polymorphism (SNP) was genotyped by using a TaqMan SNP genotyping assay. Results Individual population analyses of the selected KCNA5 genetic variant did not show significant association with SSc or any of the defined subsets (for example, limited cutaneous SSc, diffuse cutaneous SSc, anti-centromere autoantibody positive and anti-topoisomerase autoantibody positive). Furthermore, pooled analyses revealed no significant evidence of association with the disease or any of the subsets, not even the PAH-positive group. The comparison of PAH-positive patients with PAH-negative patients showed no significant differences among patients. Conclusions Our data do not support an important role of KCNA5 as an SSc-susceptibility factor or as a PAH-development genetic marker for SSc patients., This work was supported by the following grants: JM was funded by GEN-FER from the Spanish Society of Rheumatology, SAF2009-11110 from the Spanish Ministry of Science, CTS-4977 from Junta de Andalucía, Spain, in part by Redes Temáticas de Investigación Cooperativa Sanitaria Program, RD08/0075 (RIER) from Instituto de Salud Carlos III (ISCIII), Spain, and by Fondo Europeo de Desarrollo Regional (FEDER).

Abstract

The anti-Nucleolar Organizer Region 90 antibodies (NOR90) are rare antinuclear antibodies (ANA) reported in systemic sclerosis (SSc). Especially due to low prevalence, the clinical relevance of NOR90 in SSc remains uncertain. To analyze the clinical associations of NOR90 in patients with SSc in a multicentric cohort. Post-hoc, cross-sectional study of prospectively collected data from the European Scleroderma Trials and Research (EUSTAR) database, with additional information on NOR90. Further, we performed a systematic literature search, using the terms "systemic sclerosis" and "NOR90" across three databases: Medline via PubMed, Scopus, and Thomson Reuters' Web of Science Core Collection, from inception to November 1st, 2023. Overall, 1318 patients with SSc were included (mean age 58.3 ± 13.7 years, 81.3 % female), of whom 44 (3.3 %) were positive for NOR90. Of these, 32 were also positive for one of the SSc-criteria antibodies: 9/44 (20.5 %) for anti-topoisomerase I, 18/42 (42.9 %) for anti-centromere, and 5/40 (12.5 %) for anti-RNA polymerase III. NOR90-positive patients were more frequently female, had lower modified Rodnan skin score (mRSS), and lower prevalence of upper and lower gastrointestinal (GI) symptoms compared to NOR90-negative patients. In multivariable analysis, NOR90 remained significantly associated with lower mRSS and less frequent GI symptoms. The literature search identified 17 articles, including a total number of 87 NOR90-positive out of 3357 SSc patients, corresponding to an overall prevalence of 2.6 %. To our best knowledge, this is the largest SSc cohort tested for NOR90 to date, confirming the NOR90 prevalence in SSc patients is around 3 %. [ABSTRACT FROM AUTHOR]
