Metodos Un panel de expertos, seleccionados con base en su curriculum y experiencia, identifico preguntas clinicas de investigacion relevantes para el objetivo del documento. Se realizaron revisiones sistematicas de la evidencia, que se graduo de acuerdo con los criterios del Scottish Intercollegiate Guidelines Network. Tras ello, se formularon las recomendaciones. Resultados Se seleccionaron cinco preguntas, referentes a la prevencion de infeccion por Pneumocystis jirovecii con trimetoprim-sulfametoxazol, medidas profilacticas contra el virus de la hepatitis B, vacunacion contra el virus del papiloma humano, vacunacion contra el Streptococcus pneumoniae y vacunacion contra el virus de la gripe. Se formularon un total de 18 recomendaciones, estructuradas por pregunta, con base en la evidencia encontrada para las diferentes ERAS y/o consenso de expertos. Conclusiones Existe suficiente evidencia sobre la seguridad y eficacia de las vacunaciones y otras medidas profilacticas frente a los microrganismos revisados en este documento como para ser recomendadas especificamente en pacientes con ERAS.

Resumen Objectifs: Decrire la date de survenue de l’uveite anterieure aigue (UAA) par rapport aux premiers symptomes rhumatismaux et determiner son association a l’evolution de la spondyloarthrite (SpA) en ce qui concerne l’activite, les lesions structurelles, la capacite fonctionnelle et le traitement. Methodes: Il s’agit d’une etude transversale s’appuyant sur les donnees du registre REGISPONSER (registre national des SpA de la societe espagnole de rhumatologie). Trente-et-un centres ont participe et les patients atteints de SpA selon les criteres de l’ESSG ont ete inclus entre 2004 et 2007. La classification des patients s’est faite selon la date de survenue de l’uveite par rapport aux premiers signes rhumatismaux (anterieure, simultanee ou posterieure a l’apparition des symptomes). Nous avons compare les caracteristiques cliniques, l’activite de la maladie, les lesions radiographiques et la capacite fonctionnelle entre les « UAA survenues avant/simultanement aux premiers symptomes rhumatismaux » et les « UAA survenues apres les premiers symptomes ». Pour finir, nous avons analyse l’impact de la date de survenue de l’UAA sur le recours aux anti-rhumatismaux modificateurs de la maladie conventionnels et biologiques (respectivement DMARDcs et DMARDb) Resultats: Au total, 2 367 patients ont ete inclus dans le registre REGISPONSER avec une prevalence de l’UAA de 16,2 % (379 patients). Les patients dont l’UAA precedait/accompagnait les premiers signes rhumatismaux (n=59) affichaient une meilleure capacite fonctionnelle (BASFI, OR 0,85 [0,73-0,99]) et des lesions structurelles moins marquees (BASRI au rachis, OR 0,88 [0,79-0,99]). De plus, dans ce groupe de patients, l’âge d’apparition des premiers symptomes de SpA etait plus avance (OR 1,05 [1,02-1,09]) et le delai diagnostique plus court (OR 0,90 [0,84-0,96]) comparativement aux patients ayant developpe une UAA apres l’apparition des manifestations rhumatismales (n=229). Aucune difference statistiquement significative concernant l’utilisation des DMARD n’a ete observee (27,9 % vs 23,2 % pour l’utilisation des DMARDcs et 15,3 % vs 20,3 % pour l’utilisation des DMARDb chez les patients avec une UAA survenue respectivement avant/simultanement vs apres les premiers signes rhumatismaux). Conclusion: Les patients qui presentaient un premier episode d’UAA avant/simultanement aux premiers symptomes rhumatismaux avaient une forme moins severe de la maladie (meilleure capacite fonctionnelle et dommages structuraux limites) et un delai diagnostique plus court ; cependant, la date de survenue de l’UAA n’a montre aucun effet sur les traitements administres.

An inverse association between alcohol consumption and disease activity and functional impairment has been observed in patients with spondyloarthritis (SpA). However, neither this association nor the influence of smoking has been investigated in peripheral manifestations of SpA.The objective of this study was to analyze the association between smoking and alcohol consumption and the presence of peripheral musculoskeletal manifestations (arthritis, enthesitis or dactylitis) and to determine the specific location of these manifestations.Patients from the worldwide cross-sectional ASAS-PerSpA study with a diagnosis of axial SpA (axSpA), peripheral SpA (pSpA) or psoriatic arthritis (PsA) according to their rheumatologist were included. Generalised linear mixed models used peripheral manifestation (or location) as a dependent variable, smoking status and alcohol consumption as fixed effects and country as a random effect. The interaction between smoking and alcohol was tested. Analyses were performed for each diagnosis (axSpA, pSpA and PsA).A total of 4181 patients were included. In axSpA patients, smoking was associated with a lower prevalence of any peripheral manifestation, and current alcohol consumption was associated with a lower prevalence of both current arthritis and current enthesitis. In pSpA patients, current alcohol consumption was associated with a lower prevalence of current arthritis or enthesitis. In PsA patients, a significant association was found for arthritis with smoking and for enthesitis with alcohol consumption, and current alcohol consumption was associated with a lower prevalence of current arthritis or enthesitis.Taking into account the country, smoking and alcohol are associated with a lower prevalence of peripheral manifestations.

Objectives: To describe the frequency of COVID-19 and the effect of vaccination in patients with interstitial lung disease and systemic autoimmune disease (ILD-SAD) and to identify factors associated with infection and severity of COVID-19. Methods: We performed a cross-sectional multicenter study of patients with ILD-SAD followed between June and October 2021. The main variable was COVID-19 infection confirmed by a positive polymerase chain reaction (PCR) result for SARS-CoV-2. The secondary variables included severity of COVID-19, if the patient had to be admitted to hospital or died of the disease, and vaccination status. Other variables included clinical and treatment characteristics, pulmonary function and high-resolution computed tomography. Two logistic regression was performed to explore factors associated with “COVID-19” and “severe COVID-19”. Results: We included 176 patients with ILD-SAD: 105 (59.7%) had rheumatoid arthritis, 49 (27.8%) systemic sclerosis, and 22 (12.54%) inflammatory myopathies. We recorded 22/179 (12.5%) SARS-CoV-2 infections, 7/22 (31.8%) of them were severe and 3/22 (13.22%) died. As to the vaccination, 163/176 (92.6%) patients received the complete doses. The factors associated with SARS-CoV-2 infection were FVC (OR (95% CI), 0.971 (0.946–0.989); p = 0.040), vaccination (OR (95% CI), 0.169 (0.030–0.570); p = 0.004), and rituximab (OR (95% CI), 3.490 (1.129–6.100); p = 0.029). The factors associated with severe COVID-19 were the protective effect of the vaccine (OR (95% CI), 0.024 (0.004–0.170); p < 0.001) and diabetes mellitus (OR (95% CI), 4.923 (1.508–19.097); p = 0.018). Conclusions: Around 13% of patients with ILD-SAD had SARS-CoV-2 infection, which was severe in approximately one-third. Most patients with severe infection were not fully vaccinated.

Objetivos Describir la metodología del Registro de pacientes con miopatía inflamatoria idiopática (MII) de España (Myo-Spain), así como sus fortalezas y limitaciones. El objetivo principal del proyecto es analizar la evolución y el manejo clínico de una cohorte de pacientes con MII. Material y método Estudio observacional, longitudinal, ambispectivo y multicéntrico de una cohorte de pacientes con MII atendidos en servicios de reumatología de España. Se incluirán todos los pacientes con diagnóstico de MII en seguimiento habitual por los centros participantes, sin tener en cuenta la edad de inicio del proceso. Los casos incidentes serán todos los pacientes que al inicio del estudio en cada centro estén diagnosticados desde hace menos de 12 meses y casos prevalentes desde hace más de 12 meses. Se construirá un registro en el que se incluirán los datos de la visita basal, del año y dos años. Se recogerán variables sociodemográficas, clínicas, analíticas, complicaciones, comorbilidad, asociación con otras enfermedades reumáticas, ingresos hospitalarios, mortalidad y tratamientos. Además, se determinarán índices, escalas y cuestionarios de actividad, afectación muscular, daño, discapacidad y calidad de vida. El periodo de reclutamiento será de 23 meses. El propósito es conseguir una cohorte de 400 pacientes con MII. Conclusiones El estudio Myo-Spain constituye la oportunidad para desarrollar una cohorte de pacientes incidentes y prevalentes con MII en España. Myo-Spain permitirá evaluar en detalle, las características clínicas de la enfermedad en diferentes momentos. Se espera que la información exhaustiva recogida en las visitas suponga una amplia fuente de datos para futuros análisis. 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.

Objectives: To analyze the efficacy and safety of rituximab (RTX) in connective tissue disease associated with interstitial lung disease (CTD-ILD). Methods: We performed a multicenter, prospective, observational study of patients with CTD-ILD receiving rituximab between 2015 and 2020. The patients were assessed using high-resolution computed tomography and pulmonary function tests at baseline, at 12 months, and at the end of follow-up. The main outcome measure at the end of follow-up was forced vital capacity (FVC) > 10% or diffusing capacity of the lungs for carbon monoxide (DLCO) > 15% and radiological progression or death. We recorded clinical characteristics, time to initiation of RTX, concomitant treatment, infections, and hospitalization. A Cox regression analysis was performed to identify factors associated with worsening ILD. Results: We included 37 patients with CTD-ILD treated with RTX for a median (IQR) of 38.2 (17.7–69.0) months. At the end of the follow-up, disease had improved or stabilized in 23 patients (62.1%) and worsened in seven (18.9%); seven patients (18.9%) died. No significant decline was observed in median FVC (72.2 vs. 70.8; p = 0.530) or DLCO (55.9 vs. 52.2; p = 0.100). The multivariate analysis showed the independent predictors for worsening of CTD-ILD to be baseline DLCO (OR (95% CI), 0.904 (0.8–0.9); p = 0.015), time to initiation of RTX (1.01 (1.001–1.02); p = 0.029), and mycophenolate (0.202 (0.04–0.8); p = 0.034). Only 28 of the 37 patients (75.6%) were still undergoing treatment with RTX: two patients (5.4%) stopped treatment due to adverse events and seven patients (18.9%) died owing to progression of ILD and superinfection. Conclusion: Lung function improved or stabilized in more than half of patients with CTD-ILD treated with RTX. Early treatment and combination with mycophenolate could reduce the risk of progression of ILD.
