RESUMEN
OBJECTIVES: To evaluate risk factors for severe Coronavirus Disease 2019 (COVID-19) in patients with immune-mediated rheumatic diseases, stratified by systemic autoimmune conditions and chronic inflammatory arthritis. METHODS: An observational, cross-sectional multicenter study was performed. Patients from 10 Rheumatology departments in Madrid who presented with SARS-CoV-2 infection between Feb 2020 and May 2021 were included. The main outcome was COVID-19 severity (hospital admission or mortality). Risk factors for severity were estimated, adjusting for covariates (sociodemographic, clinical and treatments), using logistic regression analyses. RESULTS: 523 patients with COVID-19 were included, among whom 192 (35.6%) patients required hospital admission and 38 (7.3%) died. Male gender, older age and comorbidities such as diabetes mellitus, hypertension and obesity were associated with severe COVID-19. Corticosteroid doses over 10 mg/day, rituximab, sulfasalazine and mycophenolate use, were independently associated with worse outcomes. COVID-19 severity decreased over the different pandemic waves. Mortality was higher in the systemic autoimmune conditions (univariate analysis, p<0.001), although there were no differences in overall severity in the multivariate analysis. CONCLUSIONS: This study confirms and provides new insights regarding the harmful effects of corticosteroids, rituximab and other therapies (mycophenolate and sulfasalazine) in COVID-19. Methotrexate and anti-TNF therapy were not associated with worse outcomes.
RESUMEN
BACKGROUND AND OBJECTIVE: Rheumatic diseases account for almost 30% of consultations attended in Spanish primary care centres. The main objective was to analyse the demand for rheumatology consultations from Primary Care and their resolution using the electronic consultation system. PATIENTS AND METHODS: Retrospective descriptive study of electronic consultations from primary care centres in the health area to the Rheumatology service of a tertiary hospital, between July 2020 and May 2021. RESULTS: The last 500 consecutive consultations were collected. Mean age of patients was 59.5 years; 74.2% were women. Main reasons for consultation were osteoporosis and treatment of patients with rheumatoid arthritis and spondyloarthritis under follow-up by the department. Mean response time was 2 days. Fifty-seven per cent of patients required outpatient appointments. DISCUSSION: Over 40% of queries were resolved thanks to the electronic consultation system in an average of 2 days, otherwise patients would have been referred to specialized care.
