Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents a significant challenge for both diagnosis and treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice guidelines for Latin American patients with lupus. Two independent teams (rheumatologists with experience in lupus management and methodologists) had an initial meeting in Panama City, Panama, in April 2016. They selected a list of questions for the clinical problems most commonly seen in Latin American patients with SLE. These were addressed with the best available evidence and summarised in a standardised format following the Grading of Recommendations Assessment, Development and Evaluation approach. All preliminary findings were discussed in a second face-to-face meeting in Washington, DC, in November 2016. As a result, nine organ/system sections are presented with the main findings; an ‘overarching’ treatment approach was added. Special emphasis was made on regional implementation issues. Best pharmacologic options were examined for musculoskeletal, mucocutaneous, kidney, cardiac, pulmonary, neuropsychiatric, haematological manifestations and the antiphospholipid syndrome. The roles of main therapeutic options (ie, glucocorticoids, antimalarials, immunosuppressant agents, therapeutic plasma exchange, belimumab, rituximab, abatacept, low-dose aspirin and anticoagulants) were summarised in each section. In all cases, benefits and harms, certainty of the evidence, values and preferences, feasibility, acceptability and equity issues were considered to produce a recommendation with special focus on ethnic and socioeconomic aspects. Guidelines for Latin American patients with lupus have been developed and could be used in similar settings.
OBJECTIVE: To estimate the prevalence and analyze risk factors associated to osteoporosis and low-trauma fracture in women. METHODS: Cross-sectional study including a total of 4,332 women older than 40 attending primary care services in the Greater São Paulo, Southeastern Brazil, between 2004 and 2007. Anthropometrical and gynecological data and information about lifestyle habits, previous fracture, medical history, food intake and physical activity were obtained through individual quantitative interviews. Low-trauma fracture was defined as that resulting from a fall from standing height or less in individuals 50 years or older. Multiple logistic regression models were designed having osteoporotic fracture and bone mineral density (BMD) as the dependent variables and all other parameters as the independent ones. The significance level was set at p<0.05. RESULTS: The prevalence of osteoporosis and osteoporotic fractures was 33% and 11.5%, respectively. The main risk factors associated with low bone mass were age (OR=1.07; 95% CI: 1.06;1.08), time since menopause (OR=2.16; 95% CI: 1.49;3.14), previous fracture (OR=2.62; 95% CI: 2.08;3.29) and current smoking (OR=1.45; 95% CI: 1.13;1.85). BMI (OR=0.88; 95% CI: 0.86;0.89), regular physical activity (OR=0.78; 95% CI: 0.65;0.94) and hormone replacement therapy (OR=0.43; 95% CI: 0.33;0.56) had a protective effect on bone mass. Risk factors significantly associated with osteoporotic fractures were age (OR=1.05; 95% CI: 1.04;1.06), time since menopause (OR=4.12; 95% CI: 1.79;9.48), familial history of hip fracture (OR=3.59; 95% CI: 2.88;4.47) and low BMD (OR=2.28; 95% CI: 1.85;2.82). CONCLUSIONS: Advanced age, menopause, low-trauma fracture and current smoking are major risk factors associated with low BMD and osteoporotic fracture. The clinical use of these parameters to identify women at higher risk for fractures might be a reasonable strategy to improve the management of osteoporosis.
Hydroxychloroquine and chloroquine, also known as antimalarial drugs, are widely used in the treatment of rheumatic diseases and have recently become the focus of attention because of the ongoing COVID-19 pandemic. Rheumatologists have been using antimalarials to manage patients with chronic immune-mediated inflammatory rheumatic diseases for decades. It is an appropriate time to review their immunomodulatory and anti-inflammatory mechanisms impact on disease activity and survival of systemic lupus erythematosus patient, including antiplatelet effect, metabolic and lipid benefits. We also discuss possible adverse effects, adding a practical and comprehensive approach to monitoring rheumatic patients during treatment with these drugs.
Background: Vessel wall inflammation, atherosclerosis and hypercoagulability may be responsible for ischemic events in Takayasu arteritis (TA). No study has evaluated the effect of antiplatelet therapy for the prevention of ischemic events in TA. Methods and Results:Forty-eight patients who met the ACR Classification Criteria for TA under follow-up at the Vasculitis Unit of Universidade Federal de São Paulo were evaluated retrospectively for clinical manifestations, therapy and arterial ischemic events. The mean age at study was 38.0 years and the mean age at TA diagnosis was 29.1 years. Women comprised for 89.6% of patients and 60.4% were Caucasian. Risk factors for cardiovascular disease were found in 44 patients (91.7%) The most common comorbidities for TA patients were hypertension (77.1%), high low-density lipoprotein (45.8%) and obesity (16.7%). Antiplatelet therapy was used by 62.5% of patients whereas anticoagulants were used by 12.5%. Acute ischemic events occurred in 29.2% of patients. TA patients with ischemic events used significantly less antiplatelet agents (14.3%) than those without ischemic events (82.4%), P<0.0001. No difference concerning ischemic events was observed in patients on anticoagulant therapy (P=0.339). The 3 deaths of TA patients were observed only in those who had presented ischemic events (P=0.021). Antiplatelet agents had a protective effect against ischemic events (hazard ratio =0.055, 95% confidence interval: 0.06-0.514; P=0.011). Conclusions:Antiplatelet therapy is associated with a lower frequency of ischemic events in patients with TA. Antiplatelet Therapy in Takayasu Arteritis review of medical records of forty-eight patients who fulfilled the 1990 American College of Rheumatology criteria for TA and were under regular follow-up at the Vasculitis Unit in the Universidade Federal de São Paulo (Unifesp). 13 All of the 52 TA patients registered at our Vasculitis Unit were screened for this study, but 4 of them had to be excluded due to incomplete medical records. Medical appointments were scheduled within every one to 3 months in order to evaluate patients for the activity and progression of TA. Blood samples were collected before each visit for complete blood counts, erythrocyte sedimentation rates, lipid profiles, fasting glucose, liver enzymes and renal function. The decision to prescribe aspirin was made by the assistant physician. Statins were prescribed when serum low-density lipoprotein (LDL) levels exceeded 130 mg/dl.The present study was approved by the Institutional Ethics Committee. We collected information about demographic characteristics, disease features, arteriographic classification of TA, risk factors for cardiovascular diseases (CVD), acute ischemic events and medication used by the patients, including corticosteroids, immunosuppressive drugs, statins, anticoagulant and antiplatelet therapy. 14 The commencement dates for antiplatelet and anticoagulant therapy and of acute ischemic events were collected carefully. Time since the onset of symptoms suggestive o...
Objectives To identify potential predictors of COVID-19 vaccine hesitancy (C19-VH) in adults with immune-mediated inflammatory diseases (IMID). Methods A total of 1,000 IMID patients were enrolled in this web-based cross-sectional study. A standardised and self-administered survey was designed by members of the Brazilian Society of Rheumatology Steering Committee for Infectious and Endemic diseases and distributed to IMID patients spread across Brazil. Results Of the 908 (90.8%) respondents eligible for analysis, 744 (81.9%) were willing to get vaccinated against COVID-19. In our multivariable logistic regression model, concurrent malignancy, fibromyalgia, hydroxychloroquine use, and recent corticosteroid pulse therapy were independently associated with higher odds of C19-VH. The short duration of COVID-19 vaccine clinical trials was the main reason for C19-VH. Conclusion We identified novel characteristics potentially associated with C19-VH among adults with IMID. Greater awareness on the safety and efficacy of COVID-19 vaccines is needed for both IMID patients and attending physicians.
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.
Background: It has long been established that obesity plays a positive role against osteoporosis (OP) and lowimpact fractures (Fx). However, more recent data has shown higher fracture risk in obese individuals. The aim of this study was to investigate the association between BMI, particularly obesity, OP and low-impact Fx in Brazilian women, as well as to evaluate the SAPORI (Sao Paulo Osteoporosis Risk Index) tool performance to identify low BMD according BMI category. Methods: A total of 6182 women aged over 40 years were included in this cross-sectional analysis using data from two large Brazilian studies. All participants performed hip and spine bone mineral density (BMD) measurements and answered a detailed questionnaire about the presence of clinical risk factors (CRFs) related to low BMD and risk fractures. The World Health Organization (WHO) criteria were used to define obesity. Results: Age-adjusted osteoporosis prevalence was 20.8, 33.6, 47 and 67.1% in obese, overweight, normal and underweight category, respectively. Obesity was present in 29,6% (1.830 women) in the study population and the likelihood of osteoporosis and low-impact Fx compared to a normal BMI in this subgroup was of 0.24 (95% CI 0.20-0.28; p < 0.001) and of 1.68 (95% CI 1.35-2.11; p < 0.001), respectively. However, the hip Fx likelihood was lower in obese compared with non-obese women (OR = 0.44; 95% CI 0.20-0.97). Using an originally validated cutoff , the SAPORI tool sensitivity was significantly hampered in overweight and obese women although the accuracy had remained suitable because of increasing in specificity. Conclusions: The osteoporosis prevalence reduced as BMI increased and obesity was associated with low-impact Fx, regardless of the BMD measurements. Moreover, the SAPORI performance was impaired in obese women.
Objective To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process. Methods A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree. Nineteen questions were addressed and discussed via teleconference to formulate the answers. In order to identify the relevant data on COVID-19 vaccines, a search with standardized descriptors and synonyms was performed on September 10th, 2021, of the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and LILACS to identify studies of interest. We used the Newcastle–Ottawa Scale to assess the quality of nonrandomized studies. Results All the nineteen questions-answers (Q&A) were approved by the BSR Task Force with more than 80% of panelists voting options 4—agree—and 5—strongly agree—, and a consensus was reached. These Guidelines were focused in SMD on the most appropriate timing for IMRD patients to get vaccinated to reach the adequate covid-19 vaccination response. Conclusion These guidelines were developed by a BSR Task Force with a high LOA among panelists, based on the literature review of published studies and expert opinion for COVID-19 vaccination in IMRD patients. Noteworthy, in the pandemic period, up to the time of the review and the consensus process for this document, high-quality evidence was scarce. Thus, it is not a substitute for clinical judgment.
