RESUMEN
Patients with immune-mediated rheumatic diseases (IMRD) are at increased risk of infections, including significant morbidity and high mortality. Considering the potential for unfavorable outcomes of SARS-CoV-2 infection in patients with IMRD, a huge number of questions were released regarding the impact of COVID-19 in the beginning of the pandemic. Seeking to better understand this complex interaction, this study was developed to evaluate prospectively patients with IMRD and a suspected or confirmed COVID-19 diagnosis, according to the Ministry of Health of Brazil’s definitions. The primary outcomes will be the IMRD disease activity changes after COVID-19, at four time points: (1) At baseline and prior 6 months; (2) The first rheumatic evaluation after known infection by SARS-CoV-2 (4-6 weeks); (3) 3 months after the inclusion (±15 days); (4) 6 months after inclusion (±15 days). The secondary outcomes will be the progression rate to severe forms of COVID-19, need for intensive care unit admission and mechanical ventilation, death and therapeutic changes related to the IMRD. Two outcomes are of particular interest considering the COVID-19 in IMRD patients, namely pulmonary and the thromboembolic events, and they will be monitored with more attention and details (clinical, lab, function tests and imaging). This protocol was approved by the Brazilian Committee of Ethics in Human Research (CONEP) on April 5th, 2020 (CAAE 30186820.2.1001.8807; Number: 3.933.204) and registered on the Brazilian Registry of Clinical Trials – REBEC (RBR-33YTQC) in June, 1st 2020. We believe this study will provide many clinically relevant data on the general impact of COVID-19 on IMRD patients.
