Introduction Rheumatoid arthritis (RA) is a well-documented independent risk factor for cardiovascular disease. Obesity may provide an additional link between inflammation and accelerated atherosclerosis in RA. Objective To evaluate the association between obesity and disease parameters and cardiovascular risk factors in RA patients. Method Cross-sectional study of a cohort of RA patients from three Brazilian teaching hospitals. Information on demographics, clinical parameters and the presence of cardiovascular risk factors was collected. Blood pressure, weight, height and waist circumference (WC) were measured during the first consultation. Laboratory data were retrieved from medical records. Obesity was defined according to the NCEP/ATPIII and IDF guidelines. The prevalence of obesity was determined cross-sectionally. Disease activity was evaluated using the DAS28 system (remission < 2.6; low 2.6–3.1; moderate 3.2–5.0; high > 5.1). Results The sample consisted of 791 RA patients aged 54.7 ± 12.0 years, of whom 86.9% were women and 59.9% were Caucasian. The mean disease duration was 12.8 ± 8.9 years. Three quarters were rheumatoid factor-positive, the mean body mass index (BMI) was 27.1 ± 4.9, and the mean WC was 93.5 ± 12.5 cm. The observed risk factors included dyslipidemia (34.3%), type-2 diabetes (15%), hypertension (49.2%) and family history of premature cardiovascular disease (16.5%). BMI-defined obesity was highly prevalent (26.9%) and associated with age, hypertension and dyslipidemia. Increased WC was associated with diabetes, hypertension, dyslipidemia and disease activity. Conclusion: Obesity was highly prevalent in RA patients and associated with disease activity.

It is recommended to evaluate the presence of latent tuberculosis infection (LTBI) prior to the use of antitumor necrosis factor α. The aim of this study is to assess the presence of LTBI in patients with rheumatic diseases undergoing treatment with infliximab in an endemic area for tuberculosis (TB). LTBI was searched through the contact history, chest X-ray and tuberculin skin test with purified protein derivative (PPD) ≥5 mm. We studied 157 patients in the period from May 2005 to October 2008, 99 (63.1%) were women with average age of 49 years and 58 (36.9%) were men with average age of 41 years. The group comprising 90 patients (57.3%) with rheumatoid arthritis (RA), 54 (34.4%) with ankylosing spondylitis (AS) and 13 (8.3%) with psoriatic arthritis (PsA) had PPD reactor 13.4% (21/157), being prevented by isoniazid (INH) in these patients. There are dissimilar responsiveness to the PPD between the three pathologies, and the reactivity was lower in RA (RA × AS: χ 2  = 12; P  = 0.0004; and RA × PsA: χ 2 with Yates’ correction = 3.6; P  = 0.05). No significant difference between the reactivity of the PPD and the use of immunosuppressive drugs ( P  = 0.81) is observed. The immunoprophylaxis with INH showed an efficacy of 95% (20/21); three (1.9%) patients developed active TB (spondylodiscitis, meningitis and lymphadenopathy) after the use of infliximab, reaffirming extrapulmonary involvement. These results suggest that PPD has a low sensitivity for detection of LTBI in RA and that the previous use of immunosuppressive drugs does not affect the response to PPD.

IntroductionBiosimilars reduce the cost of biologic therapy without compromising safety and effectiveness. In this study we evaluated Brazilian rheumatologists’ knowledge and perceptions of biosimilars.MethodsCross-sectional and descriptive study based on a questionnaire containing 17 items on familiarity, knowledge and perceptions of biosimilars.ResultsAnswers were received from 135 rheumatologists, of whom 97.8% were familiar with biosimilars and 92.5% had at some time prescribed them, but only 47.7% felt comfortable prescribing them to stable patients and 62.2% strongly disagreed with automatic substitution. In addition, 51.9% preferred naive patients when starting treatment with biosimilars.ConclusionDespite the growing acceptance of biosimilars, many physicians remain reluctant. Evidence-based continuing education is essential to clarify these issues.

Myeloneuropathy is rare complication of Chikungunya virus (CHIKV) infection which may have an underlying immune-mediated pathogenesis. We describe a 31-year old female patient with systemic lupus erythematosus (SLE) presenting with acute/hyperacute bulbar and medullary fever syndrome with ascending tetraparesis associated with arthritis, requiring differential diagnosis. The analysis of the cerebrospinal fluid (CSF) revealed inflammatory markers, high protein levels, high lymphocyte and neutrophil counts, and reduced glucose. Neuroimaging showed amorphous foci of hyperintensity in T2, suggesting extensive medullary edema, especially in the central region, with no significant contrast enhancement, along with areas of medullary atrophy consistent with holocord longitudinally extensive transverse myelitis and periventricular and periaqueductal involvement. CHIKV IgM antibodies were also detected in the CSF. The present case highlights the importance of investigating atypical neurological syndromes in SLE and of including CHIKV infection, though rare, in the differential diagnosis of patients from endemic regions in order to minimize morbidity and mortality.

The COVID-19 pandemic has resulted in social isolation, which has a potential negative impact on the educational routines (eg, the suspension of face-to-face appointments) and mental health of medical students. The Mario Pinotti II (MPII) study is a 24-week observational study that conducted scheduled telephone calls every 2 weeks to verify the occurrence of COVID-19 in patients with rheumatic diseases on chronic hydroxychloroquine therapy (from March 29, 2020, to September 30, 2020). The effects of voluntarily participating in a research project (ie, one that involves interactions via telephone contact with patients, professors, rheumatologists, and colleagues) on the daily lives and mental health of medical students requires evaluation. As medical students are professionals in training and have a high level of responsibility in terms of handling the emotional and physical aspects of several diseases, this study aims to evaluate the impacts of the COVID-19 pandemic and participation in the MPII study on the educational routines and mental health of medical students. A web-based survey was carried out to perform a cross-sectional comparative assessment of medical students who participated in the MPII study and their colleagues who were not involved in the MPII study. Participants from both groups were matched based on sex, age, and medical school. The web questionnaire was developed by a panel composed of graduate medical students, rheumatologists, medical school professors, and a psychology professor. The questionnaire included details on demographic and life habits data and evaluated participants' impressions of the MPII study and the impact of the COVID-19 pandemic on their educational routines and medical training. In addition, depression, anxiety, and stress were evaluated using the Brazilian version of the Depression, Anxiety, and Stress Scale (DASS)-21, and currently, the DASS-21 scores are grouped as those that indicate a low, moderate, or high risk of mental distress. This project was approved by the Federal University of São Paulo Ethics Committee (CAAE: 34034620.0.0000.5505). Data were collected from both medical student groups from July 20 to August 31, 2020. Data extraction was completed in September 2020. The data analysis is ongoing. We expect the results to be published in the first semester of 2021. This study will provide insight into the effects of participating in a research project on depression, anxiety, and stress, which will be determined by applying the DASS-21 to a large sample of Brazilian undergraduate medical students. We will also evaluate the impact of the COVID-19 pandemic on medical students' educational routines and medical training. DERR1-10.2196/24617.
