ABSTRACT
Objective To evaluate the incidence of COVID-19 and its main outcomes in rheumatic disease (RD) patients on hydroxychloroquine (HCQ) compared to household cohabitants (HC).Methods This is a 24-week nationwide prospective multi-centre cohort with a control group without RD and not using HCQ. All participants were monitored through scheduled phone interviews performed by health professionals. Details regarding COVID-19 symptoms, and epidemiological, clinical, and demographic data were recorded on a specific web-based platform. COVID-19 was defined according to the Brazilian Ministry of Health criteria and classified as mild, moderate or severe.Results A total of 9,585 participants, 5,164 (53.9%) RD patients on HCQ and 4,421 (46.1%) HC were enrolled from March 29th, 2020 to September 30th, 2020, according to the eligibility criteria. COVID-19 confirmed cases were higher in RD patients than in cohabitants [728 (14.1%) vs. 427 (9.7%), p<0.001] in a 24-week follow-up. However, there was no significant difference regarding outcomes related to moderate/ severe COVID-19 (7.1% and 7.3%, respectively, p=0.896). After multiple adjustments, risk factors associated with hospitalisation were age over 65 (HR=4.5;95%CI 1.35-15.04, p=0.014) and cardiopathy (HR=2.57;95%CI 1.12-5.91, p=0.026). The final survival analysis demonstrated the probability of dying in 180 days after a COVID-19 diagnosis was significantly higher in patients over 65 years (HR=20.8;95%CI 4.5-96.1) and with 2 or more comorbidities (HR=10.8;95%CI 1.1-107.9 and HR=24.8;95%CI 2.5-249.3, p=0.006, respectively).Conclusion Although RD patients have had a higher COVID-19 incidence than individuals from the same epidemiological background, the COVID-19 severity was related to traditional risk factors, particularly multiple comorbidities and age, and not to underlying RD and HCQ.
ABSTRACT
Objectives: To determine the main risk factors associated with COVID-19 in SLE patients. Methods: The Reuma CoV Brazil is a multicenter, observational, prospective cohort designed to monitor immune-mediated rheumatic diseases patients during SARS-CoV-2 pandemic in Brazil. SLE adult patients according to SLE SLICC criteria classification (2012), with and without (control group-CG) COVID-19 diagnosis were matched. Demographic data, managing of COVID-19, comorbidities, clinical characteristics (disease activity: Patient Report Outcomes-PROs, Physician Global Assessment and SLEDAI-2 K)were collected. Results: From May 2020 to January 2021, 604 SLE patients were included, 317 (52.4%) with COVID-19 and 287 (47.6%) in the CG. Both groups were homogeneous and comparable regarding sex and comorbidities. SLE patients with COVID-19 declared a lower level of social isolation (49.5% vs. 61.9%;p = 0.002), worked more commonly in health professions (10.4% vs. 3.5%;p = 0.002), presented more frequently joint (32.5% vs. 22.0%;p = 0.004) and hematological manifestations (18.0% vs. 11.5%;p = 0.025). SLEDAI-2 K did not differ among groups prior and after COVID-19 infection. However, considering the mean duration of COVID-19 symptoms (12.1 ± 8.8 days), infected patients had more severe disease activity's PROs after resolution of COVID-19 symptoms (2.9 ± 2.9 vs. 2.3 ± 2.6;p = 0.031). The hospitalization rate was 20.5% (n = 65), of whom 23 (7.2%) needed intensive care unit and 14 (4.4%) patients died. Hypertension [5,26 (1,9714,07);p = 0.001] and recently cyclophosphamide pulses [39,21 (4,17-368,53);p = 0.001] were associated with hospitalization and patients who received telemedicine medical care presented 72% less chance of hospitalization [0.28 (0.09-0.83);p = 0.023). Conclusion: COVID-19 was associated with a lower level of declared social isolation and more severe disease activity perception after SARS-CoV-2 infection according to PROs. Hypertension and cyclophosphamide were associated with hospitalization and telemedicine can be a useful tool for SLE patients with COVID-19. These data should be considered to perform public health policy and national guidelines to manage SLE patients during the pandemic, as well as to prioritize some special groups for the immunization program.
