Predictors of serious infections in rheumatoid arthritis-a prospective Brazilian cohort.

BACKGROUND: Infections increase mortality and morbidity and often limit immunosuppressive treatment in rheumatoid arthritis patients. OBJECTIVE: To analyze the occurrence of serious infections and the associated factors in a cohort of rheumatoid arthritis patients under real-life conditions. METHODS: We analyzed data from the REAL, a prospective observational study, that evaluated Brazilian RA patients, with clinical and laboratory data collected over a year. Univariate and multivariate analyses were performed from the adjustment of the logistic regression model Generalized Estimating Equations (GEE), with the primary outcome being the occurrence of serious infection, defined as need for hospitalization or use of intravenous antibiotics for its treatment. RESULTS: 841 patients were included with an average follow-up time of 11.2 months (SD 2.4). Eighty-nine serious infections occurred, corresponding to 13 infections per 100 patient-years. Pulmonary fibrosis, chronic kidney disease (CKD) and central nervous system disease increased the chances of serious infection by 3.2 times (95% CI: 1.5-6.9), 3.6 times (95% CI: 1.2-10.4) and 2.4 times (95% CI: 1.2-5.0), respectively. The use of corticosteroids in moderate doses increased the chances by 5.4 times (95% CI: 2.3-12.4), and for each increase of 1 unit in the health assessment questionnaire (HAQ), the chance increased 60% (95% CI: 20-120%). CONCLUSION: The use of corticosteroids at moderate doses increased the risk of serious infection in RA patients. Reduced functionality assessed by the HAQ and comorbidities were other important factors associated with serious infection in this cohort.

Do it fast! Early access to specialized care improved long-term outcomes in rheumatoid arthritis: data from the REAL multicenter observational study.

BACKGROUND: Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. METHODS: Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed "early" when the rheumatologist was the first or second physician consulted after symptoms onset, and "late" when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. RESULTS: We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6-36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: -0.25 [-0.46, -0.04] and - 0.196 [-0.306, -0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. CONCLUSIONS: Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.

Decreasing delays in the diagnosis and treatment of rheumatoid arthritis in Brazil: a nationwide multicenter observational study

Abstract Background Management delays imply worse outcomes in rheumatoid arthritis (RA) and, therefore, should be minimized. We evaluated changes in diagnostic and treatment delays regarding RA in the last decades in Brazil. Methods Adults fulfilling the ACR/EULAR (2010) criteria for RA were assessed. Delays in diagnosis and treatment, and the frequencies of early management initiation within thresholds (windows of opportunity) of 3, 6, and 12 months from symptoms onset were evaluated. The Mann-Kendall trend test, chi-squared tests with Cramer's V effect sizes and analysis of variance were conducted. Results We included 1116 patients: 89.4% female, 56.8% white, mean (SD) age 57.1 (11.5) years. A downward trend was found in diagnostic (tau = - 0.677, p < 0.001) and treatment (tau = - 0.695, p < 0.001) delays from 1990 to 2015. The frequency of early management increased throughout the period, with ascending effect sizes across the 3-, 6-, and 12-month windows (V = 0.120, 0.200 and 0.261, respectively). Despite all improvements, even in recent years (2011-2015) the diagnostic and treatment delays still remained unacceptably high [median (IQR): 8 (4-12) and 11 (5-17) months, respectively], with only 17.2% of the patients treated within the shortest, 3-month window. Conclusion The delays in diagnosis and treatment of RA decreased during the last decades in Brazil. Improvements (effect sizes) were greater at eliminating extreme delays (≥ 12 months) than in attaining really short management windows (≤ 3 months). Very early treatment was still an unrealistic goal for most patients with RA.

Rheumatoid artrhitis treatment in Brazil: data from a large real-life multicenter study

Abstract Background: Last decades witnessed great technological advances in rheumatoid arthritis (RA) management, but their implementation in clinical practice might prove difficult. Despite the efficacy demonstrated in controlled trials this information needs to be confirmed by real life data. This study assessed real-life treatment among RA patients. Methods: REAL study included Brazilian RA patients from eleven centers. Interview and medical records were performed. Continuous variables were compared using Student's t or Mann-Whitney and categorical variables were assessed with chi-square or Fisher's exact tests. Results: 1115 patients were included, women 89.5%. Median age 56.6 years, disease duration 152.5 months; 78.7% were rheumatoid fator positive; 55.2% had erosive disease; DAS28 (disease activity index-28 joints) = 3.5, HAQ (health assessment questionnaire) =0.875. The median duration of symptoms until the start of first DMARD was 12 months. A total of 529 (47.2%) patients used corticosteroids; 1022 (90.8%) were on conventional synthetic (cs) DMARDs and 406 (36.1%) on biological (b) DMARDs. Methotrexate (MTX) was the most frequent csDMARD: 748 (66.5%) patients, followed by leflunomide (LFN), used by 381 (33.9%) of patients. MTX was associated to LFN in 142 (12.6%) patients. Only five (0.4%) patients used triple therapy (MTX + hydroxychloroquine + sulfasalazine) or sulfasalazine in monotherapy. Conclusions: Despite advances in therapeutic resources, roughly half RA patients failed achieve T2T goals and 55.2% developed erosive disease. The frequent use of corticosteroids and delay in initiating DMARDs were demonstrated. Issues concerning timely access to medical care are crucial for effective management.(AU)

Causes of synthetic disease-modifying drug discontinuation in rheumatoid arthritis: Data from a large real-life cohort.

The treatment of rheumatoid arthritis (RA) has evolved rapidly in recent years. Nonetheless, conventional synthetic disease-modifying drugs (csDMARDs) remain the gold standard for RA treatment. The treatment for RA is expensive and this has a negative impact on public health. Given the low cost of csDMARDs compared to those of other treatment strategies, it is important to manage this type of treatment properly. Information on the duration of use of each drug and the reasons for their discontinuation is relevant to medical practitioners as it could improve the information available regarding side effects and their proper management. Moreover, data from clinical practice in the population can provide health care managers with information for resource allocation and optimization of csDMARD use with a consequent cost reduction in the treatment of RA. In this cross-sectional study, we aimed to describe the use of csDMARDs in public health services in Brazil, emphasizing on the duration of use and reasons for discontinuation of each drug. This study is a part of the REAL, a multicenter project that evaluated Brazilian patients with RA from eleven rheumatology services from August to October 2015. Patients were examined clinically, and an analysis of complementary exams and medical records was performed. A total of 1125 patients were included. 98.5% were women with a median age of 55.6 years. 36% and 90.84% patients were using biological disease-modifying drugs (bDMARDs) and csDMARDs, respectively. The duration of use and doses of each medication and the causes of suspension were analyzed. Most of the patients analyzed in this study were using csDMARDs for prolonged periods and methotrexate showed the longest duration of use. Interruption indexes due to ineffectiveness and side effects were analyzed. The knowledge of common adverse effects may alert attending physicians to the proper management of effective and low-cost therapeutic groups.

Which is the best cutoff of body mass index to identify obesity in female patients with rheumatoid arthritis? A study using dual energy X-ray absorptiometry body composition / Qual o melhor ponto de corte de índice de massa corporal para diagnosticar a obesidade em mulheres com artrite reumatoide? Um estudo que usa a composição corporal pela absorciometria com raios X de dupla energia

ABSTRACT Introduction: Standard anthropometric measures used to diagnose obesity in the general population may not have the same performance in patients with rheumatoid arthritis. Objective: To determine cutoff points for body mass index (BMI) and waist circumference (WC) for detecting obesity in women with rheumatoid arthritis (RA) by comparing these standard anthropometric measures to a dual-energy X-ray absorptiometry (DXA)-based obesity criterion. Patients and method: Adult female patients with more than six months of diagnosis of RA underwent clinical evaluation, with anthropometric measures and body composition with DXA. Results: Eighty two patients were included, mean age 55 ± 10.7 years. The diagnosis of obesity in the sample was about 31.7% by BMI, 86.6% by WC and 59.8% by DXA. Considering DXA as golden standard, cutoff points were identified for anthropometric measures to better approximate DXA estimates of percent body fat: for BMI value ≥ 25 kg/m2 was the best for definition of obesity in female patients with RA, with sensitivity of 80% and specificity of 60%. For WC, with 80% of sensitivity and 35% of specificity, the best value to detect obesity was 86 cm. Conclusion: A large percentage of patients were obese. The traditional cutoff points used for obesity were not suitable for our sample. For this female population with established RA, BMI cutoff point of 25 kg/m2 and WC cutoff point of 86 cm were the most appropriate to detect obesity.

RESUMO Introdução: Medidas antropométricas universalmente usadas para diagnosticar obesidade na população geral podem não apresentar a mesma performance em pacientes com artrite reumatoide. Objetivos: Determinar pontos de corte do índice de massa corporal (IMC) e da circunferência de cintura (CC) para detecção de obesidade em mulheres com artrite reumatoide (AR) por meio da comparação dessas medidas antropométricas habituais com os índices de adiposidade obtidos pela densitometria óssea por dupla emissão de raios X (DXA). Pacientes e método: Mulheres adultas com mais de seis meses de diagnóstico de AR foram submetidas a avaliação clínica com medidas antropométricas e à DXA com exame da composição corporal. Resultados: Foram incluídas 82 pacientes, média de 55± 10,7 anos. O diagnóstico de obesidade na amostra foi de 31,7% pelo IMC, 86,6% pela circunferência de cintura e 59,8% pela DXA. Considerando a DXA o padrão-ouro, o valor de IMC acima de 25 kg/m2 foi o mais adequado para definição de obesidade nas pacientes com AR, apresentou sensibilidade de 80% e especificidade de 60%. Da mesma forma, para a CC, com 80% de sensibilidade e de 35% de especificidade, o valor encontrado foi de 86 cm para se detectar a obesidade. Conclusão: Foi elevado o porcentual de pacientes obesas. Os pontos de corte tradicionalmente usados para obesidade não foram adequados para nossa amostra. Para essa população de pacientes femininas com diagnóstico de AR, o ponto de corte de 25 kg/m2 para IMC e de 86 cm para CC foi o mais adequado para definir obesidade.
