RESUMO
OBJECTIVE: To describe in detail an innovative program based on telemedicine for semi-automated prioritization of referrals from Primary Care (PC) to Rheumatology, for reproducibility purposes, and to present the results of the implementation study. METHODS: The context and situation were carefully analyzed, paying attention to all processes in place, referral numbers, waiting times, and number of complementary tests prior to discharge from Rheumatology. The composition of the team, aims, users, scope, and implementation phases were defined. Eight process indicators were established and measured before and 32 months after the program implementation. RESULTS: The program, which includes IT circuits, algorithms based on response to specific guideline-based checklists, e-consultation, and appointments based on priority, was fully implemented in our health area after a pilot study in two PC centers. After implementation, 6185 rheumatology referrals showed an e-consultation response delay of 8.95 days, and to first face-to-face visit (after e-consultation) of 12.6 (previous delay before program implementation was 83.1 days). Resolution by e-consultation reached 20% (1195 patients did not need seeing the rheumatologist to have the problem solved), and 1369 patients (32%) were discharged after the first visit. The overall resolution rate was 44.0% (2564 discharges/5830 e-consultations). From a random sample of 100 visits, only 10% of patients needed additional complementary tests to make a diagnosis and decision by Rheumatology (20.9% decrease from previous period). CONCLUSION: A careful analysis of the situation and processes, with implementation of simple IT circuits, allows for the improvement of the efficiency and resolution of problems in Rheumatology.

OBJECTIVES: Digestive involvement (DI) has been reported in 10-30% of primary Sjögren's syndrome (pSS) patients, and few studies have systematically analysed the prevalence of DI in pSS patients. The aim of this study was to describe DI prevalence in pSS patients from the Sjögrenser Study, and to analyse its clinical associations. METHODS: All patients included in the Sjögrenser study, a Spanish multicentre randomised cohort, containing demographic, clinical and histologic data, have been analysed retrospectively. Patients were classified according to the presence of DI (oesophageal, gastric, intestinal, hepatic and pancreatic), and we have performed DI clinical associations, descriptive statistics, Student t or χ2 test, and uni and multivariate logistic regression. RESULTS: From 437 included patients, 95% were women, with a median age of 58 years, 71 (16.2%) presented DI: 21 (29.5%) chronic atrophic gastritis, 12 (16.9%) oesophageal motility dysfunction, 3 (4.2%) lymphocytic colitis, 18 (25.3%) primary biliary cholangitis, 15 (21.1%) autoimmune hepatitis, 7 (9.8%) pancreatic involvement and 5 (7%) coeliac disease. Half of them developed DI at the same time or after pSS diagnosis. Patients with DI were significantly older at pSS diagnosis (p=0.032), more frequently women (p=0.009), presented more autoimmune hypothyroidism and C3 hypocomplementaemia (p=0.040), and were treated more frequently with glucocorticoids, immunosuppressant and biologic therapies. Patients with pancreatic involvement presented more central nervous system and renal involvement, Raynaud's phenomenon, lymphoma and C3/C4 hypocomplementaemia. CONCLUSIONS: DI is frequent in Sjögrenser patients, mainly in the form of autoimmune disorders, and seem to be associated with a more severe phenotype. Our results suggest that DI should be evaluated in pSS patients, especially those with more severe disease.

BACKGROUND: Evidence on abatacept (ABA) utility for rheumatoid arthritis (RA) - associated interstitial lung disease (ILD) is growing. Clinical trials have shown equivalence in subcutaneous (SC) and intravenous (IV) administration of ABA for articular manifestations. However, this has not been studied in respiratory outcomes. OBJECTIVE: To compare the effectiveness of ABA in RA-ILD patients according to the route of administration. METHODS: National retrospective multicentre study of RA-ILD patients on treatment with ABA. They were divided into 2 groups: a) IV, and b) SC. The following outcomes were analysed from baseline to final follow-up using linear mixed models: a) forced vital capacity (FVC), b) diffusing capacity of the lungs for carbon monoxide (DLCO), c) chest high resolution computed tomography (HRCT), d) dyspnoea, e) RA activity, and f) sparing corticosteroids effect. RESULTS: A total of 397 patients were included (94 IV-ABA and 303 SC-ABA), median follow-up of 24 [10-48] months. After adjustment for possible confounders, FVC and DLCO remained stable during the first 24 months without differences between IV-ABA and SC-ABA (p = 0.6304 and 0.5337). Improvement/ stability of lung lesions in HRCT was observed in 67 % of patients (75 % IV-ABA, 64 % SC-ABA; p = 0.07). Dyspnoea stabilized/ improved in 84 % of patients (90 % IV-ABA, 82 % SC-ABA; p = 0.09). RA - disease activity improved in both groups. No statistically significant differences regarding any of the variables studied between the two groups were found. ABA was withdrawn in 87 patients (21.9 %), 45 % IV-ABA and 37 % SC-ABA (p = 0.29). ILD worsening and articular inefficacy were the most common reasons for ABA discontinuation. CONCLUSION: In patients with RA-ILD, ABA seems to be equally effective regardless of the route of administration.
RESUMO
Rheumatoid arthritis (RA) is a common chronic inflammatory disease affecting primarily peripheral joints, which is only partially controlled with current treatments. RA leads to pain, disability, deformities, and life expectancy shortening. Its pathogenesis is complex involving multiple cell types and signaling pathways that we incompletely understand. One of the pathways we have elucidated starts with WNT5A signaling and contributes to the aggressive phenotype of the RA synoviocytes through RYK-RhoA/ROCK signaling. Now, we have explored the contribution of ROCK to arthritis in vivo, using the K/BxN serum-transfer arthritis model; and to osteoclastogenesis, using the arthritis model and cells from patients with inflammatory arthritis. The mice and cells were treated with the ROCK inhibitor Y-27632 that caused a significant improvement of arthritis and reduction of osteoclastogenesis. The improvement in mouse arthritis was observed in the clinical evaluation and, histologically, in synovial inflammation, cartilage damage, bone erosion, and the abundance of multinucleated TRAP+ cells. Expression of inflammatory mediators in the arthritic joints, as assessed by real-time PCR, was also significantly reduced. The effect on bone was confirmed with in vitro assays using bone marrow precursors of arthritic mice and peripheral blood monocytes of patients with inflammatory arthritis. These assays showed dramatically reduced osteoclastogenesis and bone resorption. Overall, our findings suggest that ROCK inhibition could be part of a therapeutic strategy for RA by its dual action on inflammation and bone erosion.

OBJECTIVES: To describe the methods of the Spanish Registry of patients with idiopathic inflammatory myopathy (IIM) (Myo-Spain), as well as its strengths and limitations. The main objective of the project is to analyse the evolution and clinical management of a cohort of patients with IIM. METHODS: Observational, longitudinal, ambispective and multicentre study of a cohort of patients with IIM seen in rheumatology units in Spain. All patients with a diagnosis of IMM will be included in the regular follow-up of the participating centres, regardless of age on initiation of the process. Incident cases will be all patients who at the beginning of the study have been diagnosed for less than 12 months and prevalent cases for more than 12 months. The registry will include data from the visit at baseline, one year and two years. Socio-demographic, clinical, analytical variables, complications, comorbidities, association with other rheumatic diseases, hospital admissions, mortality and treatments will be collected. In addition, indices, scales and questionnaires of activity, muscle involvement, damage, disability, and quality of life will be determined. The recruitment period will be 23 months. The purpose is to obtain a cohort of 400 patients with IMM. CONCLUSIONS: Myo-Spain registry provides the opportunity to develop a cohort of incident and prevalent patients with IMM in Spain. Myo-Spain will be able to assess in detail the clinical characteristics of the disease at different times. The comprehensive information collected during the visits is expected to provide a broad source of data for future analysis.

RESUMO
OBJECTIVES: Rheumatoid arthritis (RA) patients show low serum levels of the Ag dipeptidyl peptidase IV (DPP-IV/CD26), both soluble CD26 (sCD26) concentration and its DPP-IV activity. The aim of this study was to test if anti-DPP-IV/CD26 Abs (Anti-CD26) cleared sCD26. DESIGN & METHODS: Serum Anti-CD26 and Total titers (as comparison) of isotypes IgA, IgM and IgG as well as sCD26 concentration and DPP-IV activity were measured in a cohort of RA patients undergoing different biological and non-biological therapies (n=105) and controls (n=50). RESULTS: Anti-CD26 levels were increased approximately two-fold for each isotype in RA, were not related to the sCD26 clearance, showed several correlations with disease activity parameters, were significantly higher in smokers and they were not ACPA. Anti-CD26 Igs showed high diagnostic power (82% sensitivity and 96% specificity) and their levels differed amongst the different groups of patients stratified by the type of therapy. CONCLUSIONS: As DPP-IV/CD26 is associated to factors triggering RA in the lung and periodontal tissue, these results suggest that Anti-CD26 isotypes may participate in pathogenesis and may be useful as biomarkers for earlier diagnosis and/or precision medicine.

We studied dipeptidyl peptidase IV (DPP-IV, CD26) expression in different T helper cells and serum soluble DPP-IV/sCD26 levels in rheumatoid arthritis (RA) patients, correlated these with disease activity score (DAS), and examined how they were affected by different therapies, conventional or biological (anti-TNF, anti-CD20 and anti-IL6R or Ig-CTLA4). The percentage of CD4+CD45R0+CD26- cells was greatly reduced in patients (up to 50%) when compared with healthy subjects. Three other subsets of CD4 cells, including a CD26high Th1-associated population, changed variably with therapies. Data from these subsets (frequency and staining density) significantly correlated with DAS28 or DAS28 components but different in each group of patients undergoing the different therapies. Th17 and Th22 subsets were implicated in RA as independent CCR4+ and CCR4- populations each, with distinct CD26 expression, and were targeted with varying efficiency by each therapy. Serum DPP-IV activity rather than sCD26 levels was lower in RA patients compared to healthy donors. DPP-IV and sCD26 serum levels were found related to specific T cell subsets but not to disease activity. We conclude that, according to their CD26 expression, different cell subsets could serve to monitor RA course, and an uncharacterized T helper CD26- subset, not targeted by therapies, should be monitored for early diagnosis.
