AimTo determine characteristics associated with more severe outcomes in a global registry of people with systemic lupus erythematosus (SLE) and COVID-19.MethodsPeople with SLE and COVID-19 reported in the COVID-19 Global Rheumatology Alliance registry from March 2020 to June 2021 were included. The ordinal outcome was defined as: (1) not hospitalised, (2) hospitalised with no oxygenation, (3) hospitalised with any ventilation or oxygenation and (4) death. A multivariable ordinal logistic regression model was constructed to assess the relationship between COVID-19 severity and demographic characteristics, comorbidities, medications and disease activity.ResultsA total of 1606 people with SLE were included. In the multivariable model, older age (OR 1.03, 95% CI 1.02 to 1.04), male sex (1.50, 1.01 to 2.23), prednisone dose (1–5 mg/day 1.86, 1.20 to 2.66, 6–9 mg/day 2.47, 1.24 to 4.86 and ≥10 mg/day 1.95, 1.27 to 2.99), no current treatment (1.80, 1.17 to 2.75), comorbidities (eg, kidney disease 3.51, 2.42 to 5.09, cardiovascular disease/hypertension 1.69, 1.25 to 2.29) and moderate or high SLE disease activity (vs remission; 1.61, 1.02 to 2.54 and 3.94, 2.11 to 7.34, respectively) were associated with more severe outcomes. In age-adjusted and sex-adjusted models, mycophenolate, rituximab and cyclophosphamide were associated with worse outcomes compared with hydroxychloroquine; outcomes were more favourable with methotrexate and belimumab.ConclusionsMore severe COVID-19 outcomes in individuals with SLE are largely driven by demographic factors, comorbidities and untreated or active SLE. Patients using glucocorticoids also experienced more severe outcomes.

ObjectivesTo evaluate risk factors associated with unfavourable outcomes: emergency care, hospitalisation, admission to intensive care unit (ICU), mechanical ventilation and death in patients with immune-mediated rheumatic disease (IMRD) and COVID-19.MethodsAnalysis of the first 8 weeks of observational multicentre prospective cohort study (ReumaCoV Brasil register). Patients with IMRD and COVID-19 according to the Ministry of Health criteria were classified as eligible for the study.Results334 participants were enrolled, a majority of them women, with a median age of 45 years; systemic lupus erythematosus (32.9%) was the most frequent IMRD. Emergency care was required in 160 patients, 33.0% were hospitalised, 15.0% were admitted to the ICU and 10.5% underwent mechanical ventilation; 28 patients (8.4%) died. In the multivariate adjustment model for emergency care, diabetes (prevalence ratio, PR 1.38; 95% CI 1.11 to 1.73; p=0.004), kidney disease (PR 1.36; 95% CI 1.05 to 1.77; p=0.020), oral glucocorticoids (GC) (PR 1.49; 95% CI 1.21 to 1.85; p<0.001) and pulse therapy with methylprednisolone (PR 1.38; 95% CI 1.14 to 1.67; p=0.001) remained significant; for hospitalisation, age >50 years (PR 1.89; 95% CI 1.26 to 2.85; p=0.002), no use of tumour necrosis factor inhibitor (TNFi) (PR 2.51;95% CI 1.16 to 5.45; p=0.004) and methylprednisolone pulse therapy (PR 2.50; 95% CI 1.59 to 3.92; p<0.001); for ICU admission, oral GC (PR 2.24; 95% CI 1.36 to 3.71; p<0.001) and pulse therapy with methylprednisolone (PR 1.65; 95% CI 1.00 to 2.68; p<0.043); the two variables associated with death were pulse therapy with methylprednisolone or cyclophosphamide (PR 2.86; 95% CI 1.59 to 5.14; p<0.018).ConclusionsAge >50 years and immunosuppression with GC and cyclophosphamide were associated with unfavourable outcomes of COVID-19. Treatment with TNFi may have been protective, perhaps leading to the COVID-19 inflammatory process.

Background/Objective: The Latin American population living with lupus lacks reliable and culturally competent health education resources. We describe a Spanish and Portuguese online program to educate Latin American people about lupus.Methods: An extensive network of Latin American stakeholders participated in the program design, implementation, dissemination, and evaluation. Patients and rheumatologists selected core topics. Rheumatologists prepared the content using evidence-based data. Adaptations were conducted to meet the audience's health literacy and cultural values. Social media was used to post audiovisual resources and facilitate users' interactions with peers and educators, and a Web site was created to offer in-depth knowledge. Results:The most massive outreach was through Facebook, with more than 20 million people reached and 80,000 followers at 3 months, between the Spanish and Portuguese pages. Nearly 90% of followers were from Latin America. A high engagement and positive responses to a satisfaction survey indicate that Facebook users valued these resources. The Spanish and Portuguese Web sites accumulated more than 62,000 page views, and 71.7% of viewers were from Latin American. Conclusions:The engagement of patients and stakeholders is critical to provide and disseminate reliable lupus education. Social media can be used to educate and facilitate interactions between people affected by lupus and qualified health care professionals. Social media-based health education has extensive and scalable outreach but is more taxing for the professional team than the Web site. However, the Web site is less likely to be used as a primary education source by Latin American people because they value social interactions when seeking lupus information.

The objective of this study is to describe the prevalence of musculoskeletal symptoms (MSK-S) in the five urban geographical regions of Brazil using the Portuguese version of the Community Oriented Program for Control of Rheumatic Diseases (COPCORD) core questionnaire (CQ)-BRAZCO study. From April to May 2013, a population-based survey was conducted by applying the CQ for 5000 individuals aged over 15 years in 16 capitals of the Brazilian regions. Trained teams assessed the MSK-S and socioeconomic status. The sample consisted of representative quotas of the Brazilian population, proportional to the capitals' population density. It respected the groups' quotas of gender and age and included all socioeconomic classes, educational levels, and occupations. There were 1342 (26.9 %) participants who presented MSK-S unrelated to trauma in 7 days preceding the interview. A higher prevalence of these complaints were in females (65.2 %), elderly people, in the north region of the country (30.7 %), and a lower prevalence was found in single individuals (41.7 %) and in the south (23.3 %). The most frequent pain sites were the spine (76.7 %) and knees (49.6 %), and the mean pain intensity was 6.8 (VAS). The BRAZCO study shows that Brazilian population presents a higher rate of MSK-S unrelated to trauma than many Asian countries. These results can be applied to guide the assessment of prevalence of rheumatic diseases. Additionally, it can help in the design of policies for health care workforce organization and its accessibility, as well as to reduce the risk of rheumatic diseases at the community level.

Background: Myostatin is a protein in the TGF-β family that negatively regulates muscle mass, and follistatin is a myostatin antagonist.Objective: The aim of this study was to measure serum levels of myostatin and follistatin in idiopathic inflammatory myopathy patients and correlate these levels with muscle strength, fatigue, functional capacity, damage, and serum levels of muscle enzymes.Methods: This was a multicenter cross-sectional study including 50 patients (34 dermatomyositis and 16 polymyositis [PM]) and 52 healthy individuals (control group [CG]). The disease status was evaluated according to the International Myositis Assessment & Clinical Studies. Fatigue was rated according to the Fatigue Severity Scale, and body composition was measured using dual-energy x-ray emission densitometry. Myostatin and follistatin were measured using enzyme-linked immunosorbent assays.Results: Mean age was 50.9 ± 14.0 years, and mean disease duration was 89.2 ± 80.9 months. There were no differences in levels of myostatin (14.15 ± 9.65 vs. 10.97 ± 6.77 ng/mL; p = 0.131) or follistatin (0.53 ± 0.71 vs. 0.49 ± 0.60 ng/mL; p = 0.968) between patients and the CG. However, myostatin levels were higher in PM than CG (16.9 ± 12.1 vs. 11.0 ± 6.8 ng/ mL; p = 0.036). There was no difference in serum myostatin among patients with and without low lean mass. Patients not treated with corticosteroids had higher serum levels of myostatin than the CG. There was a weak negative correlation between follistatin and Manual Muscle Testing and a Subset of Eight Muscles and a weak positive correlation between follistatin and Healthy Assessment Questionnaire.Conclusions: Serum levels of myostatin and follistatin did not differ between dermatomyositis and PM patients and control subjects. The assessment of serum levels of myostatin and follistatin in idiopathic inflammatory myopathy patients seems not to be helpful in clinical practice.

Objective: To determine the incidence of positive CMV antigenemia (CMV-Ag) in patients with autoimmune rheumatic diseases (AIRD) and to describe the outcomes of these patients. Methods: From January 2011 to December 2014, a total of 443 patients with AIRD were enrolled in this retrospective analysis. Demographic, clinical and laboratory data, current clinical manifestations, organs affected by CMV infection, therapeutic management and outcomes were evaluated. The CMV-Ag was considered positive when one cell was detected at least. Results: CMV-Ag was requested in 70 (15.8%) patients with suspicious CMV infection and was positive in 24 (34. 3%). The incidence rate of positive CMV-Ag was 4.97% (95% CI 3.1-7.4%). Systemic lupus erythematosus (SLE) (59%), followed by ANCA-related vasculitis (18.2%) and rheumatoid arthritis (9%) were the diseases more associated with positive CMV-Ag. At the time of CMV infection, SLE patients had moderate to severe disease activity, with high frequency of positive anti-dsDNA antibody (69.2%) and complement consumption (61.5%), as well as high doses of corticosteroids and use of immunosuppressants. The main CMV sites involved were lung (45.5%), bone marrow (40. 9%) and gut (27.3%). Mortality rate was 45.5%, especially in those with higher doses of daily oral corticosteroids (107 ± 55.4 mg vs. 71.7 ± 46.3 mg; p = 0.07) and lower number of lymphocytes (309 ± 368.2/mm 3 vs. 821 ± 692.9/ mm 3 ; p = 0.06). Conclusions: Our data showed high incidence of CMV-Ag in AIRD patients, particularly those with SLE and greater disease severity. In addition, it was observed high mortality in these patients, highlighting the CMV infection should be included in differential diagnosis.
