RESUMO
Abstract Background Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. Methods Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. Results ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. Conclusion We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

RESUMO
Previous studies found that physicians working in developed countries in Europe and in the USA declared insufficient knowledge concerning immune-related adverse events (irAE) following use of immune checkpoint inhibitors (ICI) in cancer treatment. We determined this knowledge gap among rheumatologists and medical students (MS) in Brazil. A web-based structured survey or a direct interview was applied to 1428 board-certified Brazilian rheumatologists and an adapted questionnaire was sent to 840 undergraduate MS attending the last 2 years of Medical Schools in Fortaleza-CE, Brazil, in September 2019. 228 (15.9%) rheumatologists and 145 (17.2%) MS answered the survey; 136 (60%) rheumatologists worked at Institutions with Oncology service. Rheumatologists had 22.6 ± 12.6 years of medical practice, most [116 (50.9%)] worked in private practice and 9 (3.9%) were on training. Fifty-three (23.4%) declared being familiar [40 (17.6%)] or very familiar [13 (5.8%)] with irAE. Almost two-thirds declared having never managed irAE and about a third (38.6%) felt confident in managing such patients. Knowledge among rheumatologists was similar regardless of having more or less than 10 years of practice (P = 0.758). Less than 5% MS declared being familiar with ICI and most have never heard of irAE. There is a large gap concerning knowledge about ICI and irAE among rheumatologists and MS in Brazil. Continuing medical education strategies are needed to improve this knowledge.

To determine the influence of breastfeeding duration in the clinical activity of low-income juvenile idiopathic arthritis (JIA). Ninety-one JIA patients followed in Fortaleza-CE, Brazil, were cross-sectionally evaluated from May 2015 to April 2016. Breastfeeding duration was obtained by interviewing mothers. Mean age was 14.6 ± 5.2 years with 10.31 ± 3.7 years of disease duration. Polyarticular category predominated, with 39 (42.8%) patients, followed by 23 (25.3%) oligoarticular and 17 (18.7%) enthesitis-related. Forty-seven (61.8%) were receiving methotrexate isolated or combined to leflunomide, which was used by 12 (15.4%); 30 (32.9%) were on biologic DMARD with 16 (53.3%) etanercept, 8 (26.7%) adalimumab, 3 (10%) tocilizumab, and 1 (3.3%) each on infliximab, abatacept, and canakinumab. Mean(SD) CHAQ and JADAS27 were 0.37 ± 0.36 and 5.03 ± 6.1, respectively and 22 (24%) had permanent joint deformities. No family declared monthly income over US$900.00 and 32 (37.2%) earned less than US$300.00. Eighty-three (91%) were ever breastfed; over two-thirds were breastfed for more than 3 months. Those breastfed for more than 6 months had less joint deformities and a tendency to lower JADAS27 and CHAQ scores using minimally adjusted general linear or logistic models, as appropriate. Parental smoking or literacy and family income did not differ regarding breastfeeding time. This is a low-income JIA cohort with the highest breastfeeding prevalence ever reported. Breastfeeding over 6 months was associated with less disease activity.Key Point⢠Long-term breastfeeding benefits juvenile idiopathic arthritis.
