    In this study, 1,833 systemic sclerosis (SSc) cases and 3,466 controls were genotyped with the Immunochip array. Classical alleles, amino acid residues, and SNPs across the human leukocyte antigen (HLA) region were imputed and tested. These analyses resulted in a model composed of six polymorphic amino acid positions and seven SNPs that explained the observed significant associations in the region. In addition, a replication step comprising 4,017 SSc cases and 5,935 controls was carried out for several selected non-HLA variants, reaching a total of 5,850 cases and 9,401 controls of European ancestry. Following this strategy, we identified and validated three SSc risk loci, including DNASE1L3 at 3p14, the SCHIP1-IL12A locus at 3q25, and ATG5 at 6q21, as well as a suggested association of the TREH-DDX6 locus at 11q23. The associations of several previously reported SSc risk loci were validated and further refined, and the observed peak of association in PXK was related to DNASE1L3. Our study has increased the number of known genetic associations with SSc, provided further insight into the pleiotropic effects of shared autoimmune risk factors, and highlighted the power of dense mapping for detecting previously overlooked susceptibility loci

    BACKGROUND: Few studies have examined the impact of 'sit less, move more' interventions on workplace performance. This study assessed the short and mid-term impacts of and patterns of change within, a 19-week workplace web-based intervention (Walk@WorkSpain; W@WS; 2010-11) on employees´ presenteeism, mental well-being and lost work performance. METHODS: A site randomised control trial recruited employees at six Spanish university campuses (n = 264; 42 ± 10 years; 171 female), assigned by worksite and campus to an Intervention (IG; used W@WS; n = 129; 87 female) or an active Comparison group (A-CG; pedometer, paper diary and self-reported sitting time; n = 135; 84 female). A linear mixed model assessed changes between the baseline, ramping (8 weeks), maintenance (11 weeks) and follow-up (two months) phases for the IG versus A-CG on (i) % of lost work productivity (Work Limitations Questionnaire; WLQ); (ii) three scales for presenteeism (WLQ) assessing difficulty meeting scheduling demands (Time), performing cognitive and inter-personal tasks (Mental-Interpersonal) and decrements in meeting the quantity, quality and timeliness of completed work (Output); and (iii) mental well-being (Warwick-Edinburgh Mental Well-being Scale). T-tests assessed differences between groups for changes on the main outcomes. In the IG, a multivariate logistic regression model identified patterns of response according to baseline socio-demographic variables, physical activity and sitting time. RESULTS: There was a significant 2 (group) × 2 (program time points) interaction for the Time (F [3]=8.69, p = 0.005), Mental-Interpersonal (F [3]=10.01, p = 0.0185), Output scales for presenteeism (F [3]=8.56, p = 0.0357), and for % of lost work performance (F [3]=10.31, p = 0.0161). Presenteeism and lost performance rose significantly in both groups across all study time points; after baseline performance was consistently better in the IG than in the A-CG. Better performance was linked to employees being more active (Time, p = 0.041) and younger (Mental-interpersonal, p = 0.057; Output, p = 0.017). Higher total sitting time during nonworking days (Mental-interpersonal, p = 0.019) and lower sitting time during workdays (WLQ Index, p = 0.013) also improved performance. CONCLUSION: Versus an active comparison condition, a 'sit less, move more` workplace intervention effectively reduced an array of markers of lost workday productivity.

    Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement and pronounced racial and ethnic heterogeneity. The aims of the present work were (1) to describe the cumulative clinical characteristics of those patients included in the Spanish Rheumatology Society SLE Registry (RELESSER), focusing on the differences between patients who fulfilled the 1997 ACR-SLE criteria versus those with less than 4 criteria (hereafter designated as incomplete SLE (iSLE)) and (2) to compare SLE patient characteristics with those documented in other multicentric SLE registries. RELESSER is a multicenter hospital-based registry, with a collection of data from a large, representative sample of adult patients with SLE (1997 ACR criteria) seen at Spanish rheumatology departments. The registry includes demographic data, comprehensive descriptions of clinical manifestations, as well as information about disease activity and severity, cumulative damage, comorbidities, treatments and mortality, using variables with highly standardized definitions. A total of 4.024 SLE patients (91% with ≥4 ACR criteria) were included. Ninety percent were women with a mean age at diagnosis of 35.4 years and a median duration of disease of 11.0 years. As expected, most SLE manifestations were more frequent in SLE patients than in iSLE ones and every one of the ACR criteria was also associated with SLE condition; this was particularly true of malar rash, oral ulcers and renal disorder. The analysis-adjusted by gender, age at diagnosis, and disease duration-revealed that higher disease activity, damage and SLE severity index are associated with SLE [OR: 1.14; 95% CI: 1.08-1.20 (P < 0.001); 1.29; 95% CI: 1.15-1.44 (P < 0.001); and 2.10; 95% CI: 1.83-2.42 (P < 0.001), respectively]. These results support the hypothesis that iSLE behaves as a relative stable and mild disease. SLE patients from the RELESSER register do not appear to differ substantially from other Caucasian populations and although activity [median SELENA-SLEDA: 2 (IQ: 0-4)], damage [median SLICC/ACR/DI: 1 (IQ: 0-2)], and severity [median KATZ index: 2 (IQ: 1-3)] scores were low, 1 of every 4 deaths was due to SLE activity. RELESSER represents the largest European SLE registry established to date, providing comprehensive, reliable and updated information on SLE in the southern European population

    Objectives: Systemic sclerosis (SSc) and rheumatoid arthritis (RA) are autoimmune diseases that share clinical and immunological characteristics. To date, several shared SSc- RA loci have been identified independently. In this study, we aimed to systematically search for new common SSc-RA loci through an inter-disease meta-GWAS strategy. Methods: We performed a meta-analysis combining GWAS datasets of SSc and RA using a strategy that allowed identification of loci with both same-direction and opposingdirection allelic effects. The top single-nucleotide polymorphisms (SNPs) were followed-up in independent SSc and RA case-control cohorts. This allowed us to increase the sample size to a total of 8,830 SSc patients, 16,870 RA patients and 43,393 controls. Results: The cross-disease meta-analysis of the GWAS datasets identified several loci with nominal association signals (P-value < 5 x 10-6), which also showed evidence of association in the disease-specific GWAS scan. These loci included several genomic regions not previously reported as shared loci, besides risk factors associated with both diseases in previous studies. The follow-up of the putatively new SSc-RA loci identified IRF4 as a shared risk factor for these two diseases (Pcombined = 3.29 x 10-12). In addition, the analysis of the biological relevance of the known SSc-RA shared loci pointed to the type I interferon and the interleukin 12 signaling pathways as the main common etiopathogenic factors. Conclusions: Our study has identified a novel shared locus, IRF4, for SSc and RA and highlighted the usefulness of cross-disease GWAS meta-analysis in the identification of common risk loci

    Fibrotic interstitial lung disease (ILD) is a frequent and severe complication of connective tissue disease (CTD). In this narrative review, we update the most relevant differential characteristics of fibrotic ILD associated with CTD (CTD-ILD) and propose a diagnostic and therapeutic approach based on a review of the articles published between 2002 and 2022 through PubMed. The subset of ILD, mainly the radiological/histological pattern and the degree of fibrotic component, usually determines the prognosis and therapeutic strategy for these patients. Some patients with CTD-ILD can develop progressive pulmonary fibrosis (PPF) with severe deterioration of lung function, rapid progression to chronic respiratory failure, and high mortality. PPF has been described in many CTDs, mainly in systemic sclerosis and rheumatoid arthritis, and requires a multidisciplinary diagnostic and therapeutic approach to improve patient outcomes

    Our aim was to assess the value of nintedanib for non-idiopathic progressive fibrosing interstitial lung disease (non-IPF PF-ILD) and systemic sclerosis-associated ILD (SSc-ILD) in the Spanish context, using a multi-criteria decision analysis (MCDA). Following an adaptation of the Evidence and Value: Impact on DEcision Making (EVIDEM) MCDA methodology, the estimated value of nintedanib was obtained by means of an additive linear model that combined individual weights (100-points distribution) of criteria with the individual scoring of nintedanib in each criterion for every indication, assigned by a multidisciplinary committee of twelve clinicians, patients, pharmacists, and decision-makers. To assess the reproducibility, an alternative weighting method was applied, as well as a re-test of weights and scores at a different moment of time. The experts committee recognized nintedanib as an intervention with a positive value contribution in comparison to placebo for the treatment of non-IPF PF-ILD (0.50 ± 0.16, on a scale from -1 to 1) and SSc-ILD (0.40 ± 0.12), diseases which were considered as very severe and with high unmet needs. The drug was perceived as a treatment that provides an added therapeutic benefit for patients (0.06-0.07), given its proven clinical efficacy (0.05-0.06), slight improvements in patient-reported outcomes (0.01-0.02), and similar safety profile than placebo (-0.04-0.00), which will likely be positioned as a recommended therapy in the next clinical practice guidelines updates. Under this increasingly used methodology, nintedanib has shown to provide a positive value estimate for non-IPF PF-ILD and SSc-ILD when compared to placebo in Spain

    POS0907 Association between disease activity and damage in idiopathic inflammatory myopathies. Differences between incident and prevalent cases

    Background There are different measures and tools validated to evaluate disease activity and damage in idiopathic inflammatory myopathies (IIM). Disease activity and damage in patients with early diagnosis is not still well defined. Objectives To analyze disease activity outcomes and their association with damage in IIM differentiating between incident and prevalent cases. Methods Multicenter cross-sectional study of a cohort of patients included in the Spanish Registry of patients with IIM (Myo-Spain)(1). Patients were classified as incident cohort (time between diagnosis and study initiation ≤ 12 months) or prevalent cohort (> 12 months). Activity and damage data were collected at the initial visit. Differences between both groups were tested by Chi-square, Student’s t and Mann-Whitney tests. Spearman’s correlation coefficients (Rho) were used to analyze correlations between disease activity and damage measures (weak ≥ 0.2 - <0.3; moderate ≥ 0.3 <0.7; strong ≥ 0.7). Results We included 139 (67.63% women) and 417 patients (74.34% women) with a mean age at diagnosis of 54 and 48 years in the incident and prevalent cohort, respectively. Patients in the incident cohort had significantly higher disease activity measures: myositis disease activity assessment visual analogue scale (MYOACT) total, extramuscular activity of MYOACT, physician global activity (PhGA), patient global activity (PGA), manual muscle testing (MMT)8, CK, and HAQ (p 0.2). Correlations between disease activity and damage measures are showed in the Table 1. The main differences found between both cohorts were the correlations of PhGA, CK, PGD and MDI with other measures of disease activity.Sin financiación27.973 JCR (2021) Q1, 3/34 Rheumatology5.366 SJR (2021) Q1, 7/274 Biochemistry, Genetics and Molecular Biology (miscellaneous)No data IDR 2020UE
