Factors associated with hospitalizations for Covid-19 in patients with rheumatoid arthritis: data from the Reumacov Brazil registry

Abstract Background: Patients using immunosuppressive drugs may have unfavorable results after infections. However, there is a lack of information regarding COVID 19 in these patients, especially in patients with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the risk factors associated with COVID 19 hospitalizations in patients with RA. Methods: This multicenter, prospective cohort study is within the ReumaCoV Brazil registry and included 489 patients with RA. In this context, 269 patients who tested positive for COVID 19 were compared to 220 patients who tested negative for COVID 19 (control group). All patient data were collected from the Research Electronic Data Capture database. Results: The participants were predominantly female (90.6%) with a mean age of 53 ±12 years. Of the patients with COVID 19, 54 (20.1%) required hospitalization. After multiple adjustments, the final regression model showed that heart disease (OR =4.61, 95% CI 1.06-20.02. P < 0.001) and current use of glucocorticoids (OR =20.66, 95% CI 3.09-138. P < 0.002) were the risk factors associated with hospitalization. In addition, anosmia was associated with a lower chance of hospitalization (OR =0.26; 95% CI 0.10-0.67, P < 0.005). Conclusion: Our results demonstrated that heart disease and the use of glucocorticoids were associated with a higher number of hospital admissions for COVID 19 in patients with RA.

Awareness of patients receiving bisphosphonates: a cross-sectional study

Abstract The aim of this study was to evaluate the awareness of patients using bisphosphonates (BP) regarding their risks and benefits. Sixty-five patients using BP were included. Each participant completed a self-administered questionnaire consisting of 13 questions, including sociodemographic and general information on BP. Data were analyzed using descriptive statistics, and a binomial test was used to assess patient knowledge about BP, considering a 5% significance level. Fifty-nine (90.2%) patients were unaware or had never heard of BP drugs and only 3 (4.6%) knew their indications. Only 6 patients (9.2%) said they knew about the oral complications caused by BP. Sixty-three patients (96.9%) said they were not referred to the dentist before starting BP treatment. Patients using BP do not have satisfactory knowledge regarding the risks and benefits of BP. Physicians and dentists must be prepared to inform and counsel BP users about their adverse effects and possible risk factors. Our results emphasize the importance of public policies, whether individual or collective, to be taken to increase knowledge about BP to avoid medication-related osteonecrosis of the jaw.

Pericardial effusion associated with DRESS syndrome. Case report / Derrame pericárdico asociado con síndrome de DRESS. Reporte de caso

Abstract Introduction: The DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome is a rare but serious and potentially lethal occurrence of a set of signs and symptoms associated with the use certain types of drugs. This syndrome is characterized by a heterogeneous clinical manifestation that, in many cases, results in multisystemic involvement. Case presentation: A 24-year-old man from Calarcá, Colombia, visited the emergency department of the local hospital due to a three-day history of unquantified intermittent fever associated with asthenia, adynamia, anorexia, headache, myalgia, odynophagia, and upper abdominal pain. Due to his condition and based on laboratory findings, he was referred to the Clínica Central del Quindío. The patient, 20 days before the initial assessment, had been prescribed a pharmacological treatment with non-steroidal anti-inflammatory drugs and phenytoin due to a severe cranioencephalic trauma; he also presented with generalized skin rash, elevated transaminases, and moderate eosinophilia. Complementary studies reported mild pericardial effusion, so DRESS syndrome was suspected, and corticosteroid therapy was started, achieving the complete remission of the syndrome. Conclusion: Although the DRESS syndrome has a low incidence, it should always be suspected, especially in patients with cardiac and pericardial involvement. In this case, pericardial involvement was evident, demonstrating that individuals with this syndrome may present with rare symptoms that have a serious impact on their health, as they may significantly increase adverse outcomes and mortality risk.

Resumen Introducción. El síndrome de DRESS (Drug Reaction with Eosinophilia and Systemic symptoms) consiste en la ocurrencia, si bien poco frecuente, pero grave y potencialmente mortal, de un conjunto de signos y síntomas asociados al consumo de cierto tipo de medicamentos. Este síndrome se caracteriza por tener una manifestación clínica heterogénea que, en muchos casos, causa compromiso multisistémico. Presentación del caso. Hombre de 24 años de Calarcá, Colombia, que asistió al servicio de urgencias del hospital local por presentar fiebre intermitente no cuantificada durante 3 días, junto con astenia, adinamia, anorexia, cefalea, mialgias, odinofagia y dolor abdominal superior, y que, debido a su condición y resultados de laboratorio, fue remitido a la Clínica Central del Quindío. El paciente, 20 días antes de la valoración inicial, había recibido tratamiento farmacológico con antiinflamatorios no esteroides y fenitoína por traumatismo craneoencefálico severo; además presentó rash cutáneo generalizado, elevación de transaminasas y eosinofilia moderada. En los estudios complementarios se reportó derrame pericárdico leve, por lo que se sospechó síndrome de DRESS y se inició corticoterapia, lográndose así la remisión completa de la enfermedad. Conclusión. Aunque el síndrome de DRESS tiene una baja incidencia, siempre debe sospecharse, en especial en pacientes que presentan compromiso cardiaco y pericárdico. En este caso se destaca la afectación pericárdica, demostrando que en este síndrome se pueden presentar ma -nifestaciones poco frecuentes, pero con un gran impacto en su salud, ya que pueden aumentar considerablemente los desenlaces adversos y la mortalidad en estos pacientes.

Chronic use of hydroxychloroquine did not protect against COVID-19 in a large cohort of patients with rheumatic diseases in Brazil

Abstract Background: There is a lack of information on the role of chronic use of hydroxychloroquine during the SARS-CoV-2 outbreak. Our aim was to compare the occurrence of COVID-19 between rheumatic disease patients on hydroxychloroquine with individuals from the same household not taking the drug during the first 8 weeks of community viral transmission in Brazil. Methods: This baseline cross-sectional analysis is part of a 24-week observational multi-center study involving 22 Brazilian academic outpatient centers. All information regarding COVID-19 symptoms, epidemiological, clinical, and demographic data were recorded on a specific web-based platform using telephone calls from physicians and medical students. COVID-19 was defined according to the Brazilian Ministry of Health (BMH) criteria. Mann-Whitney, Chi-square and Exact Fisher tests were used for statistical analysis and two binary Final Logistic Regression Model by Wald test were developed using a backward-stepwise method for the presence of COVID-19. Results: From March 29th to May 17st, 2020, a total of 10,443 participants were enrolled, including 5166 (53.9%) rheumatic disease patients, of whom 82.5% had systemic erythematosus lupus, 7.8% rheumatoid arthritis, 3.7% Sjögren's syndrome and 0.8% systemic sclerosis. In total, 1822 (19.1%) participants reported flu symptoms within the 30 days prior to enrollment, of which 3.1% fulfilled the BMH criteria, but with no significant difference between rheumatic disease patients (4.03%) and controls (3.25%). After adjustments for multiple confounders, the main risk factor significantly associated with a COVID-19 diagnosis was lung disease (OR 1.63; 95% CI 1.03-2.58); and for rheumatic disease patients were diagnosis of systemic sclerosis (OR 2.8; 95% CI 1.19-6.63) and glucocorticoids above 10 mg/ day (OR 2.05; 95% CI 1.31-3.19). In addition, a recent influenza vaccination had a protective effect (OR 0.674; 95% CI 0.46-0.98). Conclusion: Patients with rheumatic disease on hydroxychloroquine presented a similar occurrence of COVID-19 to household cohabitants, suggesting a lack of any protective role against SARS-CoV-2 infection.

Long-Term Persistence of Serum-Specific Anti-Chikungunya IgM Antibody - A Case Series of Brazilian Patients

Abstract The persistence of serum-specific anti-chikungunya IgM antibodies (CHIKV-IgM) can vary after chikungunya fever (CHIK) infection. However, the factors related to its production are not yet known. We described a case series drawn up from data collected from 57 patients between 12 and 36 months after the acute phase of CHIK infection in Northeastern Brazil. CHIKV-IgM was detectable in 7/57 (12.3%) patients after 28.3 months of infection. No frequency differences in chronic musculoskeletal manifestations and underlying conditions were detected between patients with or without CHIKV-IgM. CHIKV-IgM was detected for up to 35 months in Brazilian patients after CHIK infection.

Psoriatic Arthritis Quality of Life Questionnaire: translation, cultural adaptation and validation into Brazilian Portuguese language

Abstract Introduction: Psoriatic arthritis (PsA) is a multifaceted inflammatory disease that can cause joint destruction and impair quality of life. The Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL) was the first disease-specific tool for determining the impact of the disease on the quality of life of people with PsA. Objectives: The primary objective was to develop and validate a Brazilian Portuguese version of the PsAQoL. Methods: The UK PsAQoL was translated into Brazilian Portuguese using two translation panels. This translation then checked for face validity and construct validity with new samples of patients. Finally, a test-retest validation study was conducted with 52 patients with PsA. The survey included the Nottingham Health Profile (NHP) as a comparator instrument. Results: Internal consistency and reproducibility were both excellent for the new adaptation (0.91 and 0.90 respectively Scores on the PsAQoL were found to correlate as expected with the comparator measure and the instrument was able to detect differences in score related to perceived severity of PsA, general health status and presence of a flare. Conclusions: The Brazilian PsAQoL was found easy to understand and complete and has excellent reliability and construct validity. The new measure will be a valuable new tool for use in routine PsA practice and clinical trials.

Evaluation of quality of life, functionality and disability in patients with systemic sclerosis in a university hospital / Avaliação da qualidade de vida, funcionalidade e deficiência em pacientes com esclerose sistêmica em um hospital universitário

INTRODUCTION: Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by progressive fibrosis of the skin and internal organs that promotes high morbidity and mortality. OBJECTIVE: To evaluate the functionality, disability and quality of life of patients with systemic sclerosis and to compare the clinical forms of the disease. METHODS: Cross-sectional, descriptive and analytical study performed at the Rheumatology Clinic of the Hospital das Clínicas of the Federal University of Pernambuco (HC-UFPE) from August 2018 to April 2019. The non-probabilistic, convenience sample consisted of 60 patients diagnosed with systemic sclerosis (SSc), followed at the Rheumatology outpatient clinic of the Hospital das Clínicas, Federal University of Pernambuco. To evaluate the outcomes, the following instruments were used: Cochin Hand Functional Scale (CHFS) for hand function; 12-Item Short-Form Health Survey (SF-12) for quality of life; and Scleroderma Health Assessment Questionnaire (SHAQ) for functionality and disability. RESULTS: The mean results for CHFS, SHAQ, SF-12 Physical Component Summary and SF-12 Mental Component Summary were 14.5 (6.0-29.75), 1.01±0.56, 35.04±8.09, 40.94±10.56, respectively. There were no significant differences in CHFS outcomes between patients with diffuse and limited forms of SSc, SHAQ and the mental component of SF-12. However, in the physical component of SF-12, a better score was found in patients with the diffuse form of the disease (p=0.04). CONCLUSION: Patients with SSc present an important impairment of hand function, quality of life and functional capacity, and those with limited cutaneous form present worse scores of the physical component in the evaluation of quality of life.

INTRODUÇÃO: A esclerose sistêmica (ES) é uma doença autoimune crônica que se caracteriza por fibrose progressiva da pele e órgãos internos, promovendo grande morbimortalidade. OBJETIVO: Avaliar a funcionalidade, incapacidade e qualidade de vida em pacientes com esclerose sistêmica e comparar as formas clínicas da doença. MÉTODOS: Estudo transversal, descritivo e analítico, realizado na Clínica de Reumatologia do Hospital das Clínicas da Universidade Federal de Pernambuco (HC-UFPE), de agosto de 2018 a abril de 2019. A amostra não probabilística do tipo conveniência foi composta por 60 pacientes com diagnóstico de ES, acompanhados no ambulatório de Reumatologia do Hospital das Clínicas da Universidade Federal de Pernambuco. Para avaliar os resultados, foram utilizados os seguintes instrumentos: Escala Funcional da Mão de Cochin (CHFS) para função da mão; 12-Item Short-Form Health Survey (SF-12) para qualidade de vida; Questionário de Avaliação de Saúde da Esclerodermia (SHAQ) para funcionalidade e incapacidade. RESULTADOS: Os resultados médios para CHFS, SHAQ, SF-12 componente físico e SF-12 componente mental foram 14,5 (6,0-29,75), 1,01±0,56; 35,04±8,09; 40,94±10,56, respectivamente. Não houve diferenças significativas nos resultados do CHFS entre pacientes com formas difusas e limitadas de ES, SHAQ e o componente mental do SF-12. No entanto, no componente físico do SF-12, foi encontrado melhor escore dos pacientes com a forma difusa da doença (p=0,04). CONCLUSÃO: Pacientes com ES apresentam comprometimento importante da função da mão, qualidade de vida e capacidade funcional, e aqueles com forma cutânea limitada apresentam piores escores do componente físico na avaliação da qualidade de vida.

Update on the treatment of musculoskeletal manifestations in chikungunya fever: a guideline

Abstract Since the emergence of the chikungunya virus in Brazil in 2014, more than 700,000 cases have been reported throughout the country, corresponding to one-third of all cases reported in the Americas. In addition to its high attack rates, resulting in hundreds of thousands of cases, the disease has high chronicity rates with persistent joint manifestations for more than 3 months, which can spread to more than half of the patients affected in the acute phase. Pain associated with musculoskeletal manifestations, often disabling, has an effect on patients' quality of life at different stages of the disease. Currently, the challenge faced by specialists is identifying the best therapy to be instituted for symptom relief despite the limited number of published intervention studies. In 2016, a multidisciplinary group published pharmacological treatment protocols for pain in patients with chikungunya, which was incorporated into the guidelines for clinical management of the Brazilian Ministry of Health in 2017; in that same year, a consensus was published by the Brazilian Society of Rheumatology about diagnosis and treatment. After 5 years of experience with chikungunya epidemics, in 2019, specialists involved in the protocols of the Brazilian Society of Rheumatology and Brazilian Ministry of Health prepared an update with the main objective of developing flowcharts for the therapeutic approach of musculoskeletal manifestations in adult patients to enable specialists at different levels of healthcare to spread and apply this guideline in a systematic and simplified manner.

Papel de Hospital Universitário na rede de atenção reumatológica / Role of University Hospital in the rheumatological care network

RESUMO Os objetivos deste artigo são descrever e analisar o papel de um Hospital Universitário na Rede de Atenção à Saúde para pacientes reumatológicos no estado de Pernambuco. Realizou-se estudo transversal com abordagem qualitativa e quantitativa. Foram entrevistados informantes-chave da Secretaria Estadual de Saúde e do Hospital das Clínicas da Universidade Federal de Pernambuco. Dados secundários foram extraídos do Cadastro Nacional de Estabelecimentos de Saúde. Em 2016, foram atendidos 4.530 usuários com Doenças Reumatológicas no hospital, média de idade de 52 anos, maioria mulheres (79%), oriundos de 164 municípios pernambucanos com concentração na 1ª região de saúde. A entrada dos pacientes é regulada, havendo protocolo de acesso para avaliar perfil e indicar subespecialidade de atendimento em reumatologia. Existe protocolo único no hospital e são garantidos exames laboratoriais e alguns por imagem; há infusão de imunossupressores no serviço, quando indicada clinicamente. Como fragilidades, apontam-se alto absenteísmo e dificuldades em compartilhar cuidado com a atenção básica, apesar da alta responsável adotada. O Hospital Universitário analisado parece cumprir sua missão institucional e funcionalidade, dando resolutividade aos casos pelos quais se torna responsável e preenchendo, muitas vezes, as lacunas assistenciais da média complexidade do Sistema Único de Saúde.

ABSTRACT The objectives of this paper was to describe and analyze the role of a University Hospital in the Health Care Network for rheumatological patients of Pernambuco state. A transversal study with qualitative and quantitative approach was carried out. Key-informants from the Health State Secretary and Clinical Hospital of the Federal University of Pernambuco were interviewed. Secondary data were extracted from the National Registry of Health Establishments. In 2016, 4.530 patients with Rheumatologic Diseases were treated at the hospital, mean age of 52 years old, mostly women (79%), from 164 municipalities in Pernambuco with concentration in the 1st health region. Patients' admission is regulated, with an access protocol to evaluate profile and indicate subspecialty of care in rheumatology. There is a single protocol in the hospital and laboratory and some imaging tests are assured; there is infusion of immunosuppressants in the service, when clinically indicated. As weaknesses, high absenteeism and difficulties in sharing care with primary care are pointed out, despite the high responsibility adopted. The University Hospital analyzed seems to fulfill its institutional mission and functionality, giving resolution to the cases for which it becomes responsible and filling, often, the assistance gaps of the average complexity of the Unified Health System.

Incidence of tuberculosis among patients with rheumatoid arthritis using TNF blockers in Brazil: data from the Brazilian Registry of Biological Therapies in Rheumatic Diseases (Registro Brasileiro de Monitoração de Terapias Biológicas - BiobadaBrasil) / Incidência de tuberculose em pacientes com artrite reumatoide em uso de bloqueadores do TNF no Brasil: dados do Registro Brasileiro de Monitoração de Terapias Biológicas BiobadaBrasil

Abstract Objectives To assess the incidence of tuberculosis and to screen for latent tuberculosis infection among Brazilians with rheumatoid arthritis using biologics in clinical practice. Patients and methods This cohort study used data from the Brazilian Registry of Biological Therapies in Rheumatic Diseases (Registro Brasileiro de Monitoração de Terapias Biológicas - BiobadaBrasil), from 01/2009 to 05/2013, encompassing 1552 treatments, including 415 with only synthetic disease-modifying anti-rheumatic drugs, 942 synthetic DMARDs combined with anti-tumor necrosis factor (etanercept, infliximab, adalimumab) and 195 synthetic DMARDs combined with other biologics (abatacept, rituximab and tocilizumab). The occurrence of tuberculosis and the drug exposure time were assessed, and screening for tuberculosis was performed. Statistical analysis: Unpaired t-test and Fisher's two-tailed test; p < 0.05. Results The exposure times were 981 patient-years in the controls, 1744 patient-years in the anti-TNF group (adalimumab = 676, infliximab = 547 and etanercept = 521 patient-years) and 336 patient-years in the other biologics group. The incidence rates of tuberculosis were 1.01/1000 patient-years in the controls and 2.87 patient-years among anti-TNF users (adalimumab = 4.43/1000 patient-years; etanercept = 1.92/1000 patient-years and infliximab = 1.82/1000 patient-years). No cases of tuberculosis occurred in the other biologics group. The mean drug exposure time until the occurrence of tuberculosis was 27(11) months for the anti-TNF group. Conclusions The incidence of tuberculosis was higher among users of synthetic DMARDs and anti-TNF than among users of synthetic DMARDs and synthetic DMARDs and non-anti-TNF biologics and also occurred later, suggesting infection during treatment and no screening failure.

Resumo Objetivos Avaliar incidência de tuberculose e triagem para tuberculose latente em brasileiros com artrite reumatoide em uso de agentes biológicos na prática clinica. Pacientes e métodos Estudo de coorte com dados do Registro Brasileiro de Monitoração de Terapias Biológicas (BiobadaBrasil), de 01/2009 a 05/2013, abrangeu 1.552 tratamentos, 415 somente com drogas modificadoras do curso da doença (MMCDs) sintéticas, 942 MMCDs sintéticas em associação com anti-TNF (etanercepte, infliximabe, adalimumabe) e 195 MMCDs sintéticas em associação com outros biológicos (abatacepte, rituximabe e tocilizumabe). Avaliaram-se ocorrência de tuberculose, tempo de exposição às drogas e triagem para TB. Análise estatística: teste t não pareado e teste de Fisher bicaudal; p < 0,05. Resultados O tempo de exposição dos controles foi de 981 pacientes-ano, do grupo de anti-TNF foi de 1.744 pacientes-ano (adalimumabe = 676, infliximabe = 547 e etanercepte = 521 pacientes-ano) e o de outros biológicos de 336 pacientes-ano. A incidência de TB foi de 1,01/1.000 pacientes-ano nos controles e de 2,87 pacientes-ano nos usuários de anti-TNF (adalimumabe = 4,43/1.000 pacientes-ano; etanercepte = 1,92/1.000 pacientes-ano e infliximabe = 1,82/1.000 pacientes-ano). Não houve casos de tuberculose no grupo de outros biológicos. O tempo médio de exposição até a ocorrência de tuberculose foi de 27(11) meses para o grupo anti-TNF. Conclusões A incidência de tuberculose foi maior nos usuários de MMCDs sintéticas e anti-TNF do que nos usuários de MMCDs sintéticas e de MMCDs sintéticas e biológicos não anti-TNF, e também mais tardia, sugerindo infecção durante o tratamento, e não falha na triagem.

Recommendations of the Brazilian Society of Rheumatology for diagnosis and treatment of Chikungunya fever. Part 1 - Diagnosis and special situations / Recomendações da Sociedade Brasileira de Reumatologia para diagnóstico e tratamento da febre chikungunya. Parte 1 - Diagnóstico e situações especiais

Abstract Chikungunya fever has become a relevant public health problem in countries where epidemics occur. Until 2013, only imported cases occurred in the Americas, but in October of that year, the first cases were reported in Saint Marin island in the Caribbean. The first autochthonous cases were confirmed in Brazil in September 2014; until epidemiological week 37 of 2016, 236,287 probable cases of infection with Chikungunya virus had been registered, 116,523 of which had serological confirmation. Environmental changes caused by humans, disorderly urban growth and an ever-increasing number of international travelers were described as the factors responsible for the emergence of large-scale epidemics. Clinically characterized by fever and joint pain in the acute stage, approximately half of patients progress to the chronic stage (beyond 3 months), which is accompanied by persistent and disabling pain. The aim of the present study was to formulate recommendations for the diagnosis and treatment of Chikungunya fever in Brazil. A literature review was performed in the MEDLINE, SciELO and PubMed databases to ground the decisions for recommendations. The degree of concordance among experts was established through the Delphi method, involving 2 in-person meetings and several online voting rounds. In total, 25 recommendations were formulated and divided into 3 thematic groups: (1) clinical, laboratory and imaging diagnosis; (2) special situations; and (3) treatment. The first 2 themes are presented in part 1, and treatment is presented in part 2.

Resumo A febre chikungunya tem se tornado um importante problema de saúde pública nos países onde ocorrem as epidemias. Até 2013, as Américas haviam registrado apenas casos importados quando, em outubro desse mesmo ano, foram notificados os primeiros casos na Ilha de Saint Martin, no Caribe. No Brasil, os primeiros relatos autóctones foram confirmados em setembro de 2014 e até a semana epidemiológica 37 de 2016 já haviam sido registrados 236.287 casos prováveis de infecção pelo chikungunya vírus (CHIKV), 116.523 confirmados sorologicamente. As mudanças ambientais causadas pelo homem, o crescimento urbano desordenado e o número cada vez maior de viagens internacionais têm sido apontados como os fatores responsáveis pela reemergência de epidemias em grande escala. Caracterizada clinicamente por febre e dor articular na fase aguda, em cerca de metade dos casos existe evolução para a fase crônica (além de três meses), com dor persistente e incapacitante. O objetivo deste trabalho foi elaborar recomendações para diagnóstico e tratamento da febre chikungunya no Brasil. Para isso, foi feita revisão da literatura nas bases de dados Medline, SciELO e PubMed, para dar apoio às decisões tomadas para definir as recomendações. Para a definição do grau de concordância foi feita uma metodologia Delphi, em duas reuniões presenciais e várias rodadas de votação on line. Foram geradas 25 recomendações, divididas em três grupos temáticos: (1) diagnóstico clínico, laboratorial e por imagem; (2) situações especiais e (3) tratamento. Na primeira parte estão os dois primeiros temas e o tratamento na segunda.

Recommendations of the Brazilian Society of Rheumatology for the diagnosis and treatment of chikungunya fever. Part 2 - Treatment / Recomendações da Sociedade Brasileira de Reumatologia para diagnóstico e tratamento da febre chikungunya. Parte 2 - Tratamento

Abstract Chikungunya fever has become an important public health problem in countries where epidemics occur because half of the cases progress to chronic, persistent and debilitating arthritis. Literature data on specific therapies at the various phases of arthropathy caused by chikungunya virus (CHIKV) infection are limited, lacking quality randomized trials assessing the efficacies of different therapies. There are a few studies on the treatment of musculoskeletal manifestations of chikungunya fever, but these studies have important methodological limitations. The data currently available preclude conclusions favorable or contrary to specific therapies, or an adequate comparison between the different drugs used. The objective of this study was to develop recommendations for the treatment of chikungunya fever in Brazil. A literature review was performed via evidence-based selection of articles in the databases Medline, SciELO, PubMed and Embase and conference proceedings abstracts, in addition to expert opinions to support decision-making in defining recommendations. The Delphi method was used to define the degrees of agreement in 2 face-to-face meetings and several online voting rounds. This study is part 2 of the Recommendations of the Brazilian Society of Rheumatology (Sociedade Brasileira de Reumatologia - SBR) for the Diagnosis and Treatment of chikungunya fever and specifically addresses treatment.

Resumo A febre chikungunya tem se tornado um importante problema de saúde pública nos países onde ocorrem as epidemias, visto que metade dos casos evolui com artrite crônica, persistente e incapacitante. Os dados na literatura sobre terapêuticas específicas nas diversas fases da artropatia ocasionada pela infecção pelo vírus chikungunya (CHIKV) são limitados, não existem estudos randomizados de qualidade que avaliem a eficácia das diferentes terapias. Há algumas poucas publicações sobre o tratamento das manifestações musculoesqueléticas da febre chikungunya, porém com importantes limitações metodológicas. Os dados atualmente disponíveis não permitem conclusões favoráveis ou contrárias a terapêuticas específicas, bem como uma adequada avaliação quanto à superioridade entre as diferentes medicações empregadas. O objetivo deste trabalho foi elaborar recomendações para o tratamento da febre chikungunya no Brasil. Foi feita uma revisão da literatura com seleção de artigos baseados em evidência, nas bases de dados Medline, SciELO, PubMed e Embase e de resumos de anais de congressos, além da opinião dos especialistas para dar apoio às decisões tomadas para definir as recomendações. Para a definição do grau de concordância foi feita uma metodologia Delphi, em duas reuniões presenciais e várias rodadas de votação on line. Este artigo refere-se à parte 2 das Recomendações da Sociedade Brasileira de Reumatologia para Diagnóstico e Tratamento da Febre Chikungunya, que trata especificamente do tratamento.

High frequency of asymptomatic hyperparathyroidism in patients with fibromyalgia: random association or misdiagnosis? / Frequência elevada de hiperparatireoidismo assintomático em pacientes com fibromialgia: associação ao acaso ou erro diagnóstico?

ABSTRACT Fibromyalgia (FM) and hyperparathyroidism may present similar symptoms (musculoskeletal pain, cognitive disorders, insomnia, depression and anxiety), causing diagnostic confusion. Objectives: To determine the frequency of asymptomatic hyperparathyroidism in a sample of patients with FM and to evaluate the association of laboratory abnormalities to clinical symptoms. Methods: Cross-sectional study with 100 women with FM and 57 healthy women (comparison group). Parathyroid hormone (PTH), calcium and albumin levels were accessed, as well as symptoms in the FM group. Results: In FM group, mean serum calcium (9.6 ± 0.98 mg/dL) and PTH (57.06 ± 68.98 pg/mL) values were considered normal, although PTH levels had been significantly higher than in the comparison group (37.12 ± 19.02 pg/mL; p = 0.001). Hypercalcemic hyperparathyroidism was diagnosed in 6% of patients with FM, and 17% of these women exhibited only high levels of PTH, featuring a normocalcemic hyperparathyroidism, with higher frequencies than those expected for their age. There was no significant association between hyperparathyroidism and FM symptoms, except for epigastric pain, which was more frequent in the group of patients concomitantly with both diseases (p = 0.012). Conclusions: A high frequency of hyperparathyroidism was noted in women with FM versus the general population. Normocalcemic hyperparathyroidism was also more frequent in patients with FM. Longitudinal studies with greater number of patients are needed to assess whether this is an association by chance only, if the increased serum levels of PTH are part of FM pathophysiology, or even if these would not be cases of FM, but of hyperparathyroidism.

RESUMO A fibromialgia (FM) e o hiperparatireoidismo podem apresentar sintomas semelhantes (dores osteomusculares, distúrbios cognitivos, insônia, depressão e ansiedade) e causar confusão diagnóstica. Objetivos: Determinar a frequência de hiperparatireoidismo assintomático em uma amostra de pacientes com FM e avaliar a associação das alterações laboratoriais com a sintomatologia. Metodologia: Estudo transversal com 100 mulheres portadoras de FM e 57 mulheres saudáveis (grupo de comparação). Foram pesquisados os níveis de paratormônio (PTH), cálcio e albumina, além da pesquisa de sintomas no grupo com FM. Resultados: No grupo com FM, os valores médios de cálcio sérico (9,6 ± 0,98 mg/dL) e de PTH (57,06 ± 68,98pg/mL) foram considerados normais, embora os níveis de PTH tivessem sido significativamente maiores do que no grupo de comparação (37,12 ± 19,02 pg/mL; p = 0,001). O hiperparatireoidismo hipercalcêmico foi diagnosticado em 6% das pacientes com FM e 17% delas apresentaram apenas PTH elevado, o que caracterizou o hiperparatireoidismo normocalcêmico, frequências maiores do que esperada para a faixa etária. Não houve associação significativa entre hiperparatireoidismo e sintomas da FM, com exceção da epigastralgia, que foi mais frequente no grupo de pacientes com as duas doenças concomitantes (p = 0,012). Conclusões: Houve frequência elevada de hiperparatireoidismo em portadoras de FM quanto à população geral. Hiperparatireoidismo normocalcêmico também foi mais frequente em pacientes com FM. Estudos longitudinais e com maior número de pacientes são necessários para avaliar se trata-se apenas de uma associação ao acaso, se as elevações séricas do PTH fazem parte da fisiopatologia da FM ou, ainda, se não seriam casos de FM, e sim de hiperparatireoidismo.

Cytokine measurements in Brazilian postmenopausal osteoporosis patients reveal high levels of IL-8 / Dosagem de citocinas em pacientes brasileiras com osteoporose pós-menopausa revela altos níveis de IL-8

AIMS: Osteoporosis is a common disease that affects mostly women and has been associated with the immune system. The aims of this study were to evaluate the serum levels of inflammatory cytokines in women with postmenopausal osteoporosis and to investigate their relationship with clinical and laboratory parameters. METHODS: This study recruited patients with postmenopausal osteoporosis (osteoporosis group) and non-osteoporotic postmenopausal women (control group) matched for age. All patients and controls had their bone mineral density measured for the diagnosis of osteoporosis and answered a clinical questionnaire. Blood samples were collected for cytokine measurements. Cytokines IFN-γ, IL-1ß, IL-6, IL-8, IL-9, IL-10, IL-17A, IL-22, IL-27, IL-29, IL-35, and TNF-α were measured by an enzyme-linked immunosorbent assay. RESULTS: Twenty-nine out of the 52 (55.8%) postmenopausal osteoporosis patients showed high levels of IL-8, while no patients from the control group (n=21) showed IL-8 values above the detection limit (p<0.0001). Higher levels of IFN-γ and IL-35 were associated with the control group, with p values of 0.0053 and 0.0214, respectively. In the osteoporosis group, IFN-γ was correlated with longer duration of smoking (p=0.003), IFN-γ and IL-6 were correlated with higher age at menarche (p=0.0454 and p=0.0380), IL-22 was correlated with duration of menopause (p=0.0289) and IL-9 with calcium intake (p=0.019). The other cytokines showed no association or correlation with clinical parameters. CONCLUSIONS: IL-8 was elevated in the serum of patients with postmenopausal osteoporosis, perhaps because it may trigger osteoclast activation and bone wear in osteoporosis. Higher levels of IFN-γ, IL-6, IL-9, IL-22, IL-27, and IL-35 were also associated with the osteoporosis group patients and showed significant correlation with clinical parameters in postmenopausal osteoporosis.

OBJETIVOS: A osteoporose é uma doença comum, que afeta principalmente as mulheres e tem sido associada com o sistema imune. Este estudo objetivou avaliar níveis séricos de citocinas inflamatórias em mulheres pós-menopáusicas com osteoporose, assim como investigar as suas relações com parâmetros clínicos e laboratoriais. MÉTODOS: Este estudo recrutou pacientes com osteoporose pós-menopausa e voluntárias sem a doença, pareadas por idade. Todas as pacientes do grupo com osteoporose e as integrantes do grupo controle passaram pelo exame de mensuração de densidade óssea para diagnosticar a doença e todas responderam a um questionário clínico. Amostras de sangue foram coletadas para as dosagens séricas. As citocinas IFN-γ, IL-1ß, IL-6, IL-8, IL-9, IL-10, IL-17A, IL-22, IL-27, IL-29, IL-35 e TNF-α foram dosadas por ensaio imunoenzimático. RESULTADOS: Vinte e nove entre as 52 (55,8%) pacientes com osteoporose pós-menopausa mostraram altos níveis de IL-8, enquanto nenhuma integrante do grupo controle teve valores de IL-8 acima do nível de detecção do kit (p<0,0001). Altos níveis de IFN-γ and IL-35 foram associados ao grupo controle, com valores de p de 0,0053 and 0,0214 respectivamente. No grupo osteoporose, IFN-γ mostrou correlação com o tempo de duração do tabagismo (p=0,003). IFN-γ e IL-6 foram correlacionadas com a idade de ocorrência da menarca (p=0,0454 e p=0,0380). A citocina IL-22 correlacionou-se com a duração da menopausa (p=0,0289), e a IL-9 com a ingestão de mais cálcio na dieta (p=0,019). As outras citocinas dosadas não mostraram associações ou correlações com os parâmetros clínicos. CONCLUSÕES: A IL-8 mostrou-se elevada no soro das pacientes com osteoporose pós-menopausa, talvez por atuar como um gatilho para a ativação dos osteoclastos e desgaste ósseo que ocorre na osteoporose. Níveis mais altos de IFN-γ, IL-6, IL-9, IL-22, IL-27 e IL-35 também estiveram presentes no soro das pacientes do grupo osteoporose e mostraram associações significativas com os parâmetros clínicos na osteoporose pós-menopausa.

Qualidade de vida nas espondiloartrites: análise de uma grande coorte brasileira / Quality of life in spondyloarthritis: analysis of a large Brazilian cohort

Resumo Objetivo: Analisar as variáveis demográficas e clínicas associadas à diminuição da qualidade de vida em uma grande coorte brasileira de pacientes com espondiloartrite (EpA). Métodos: Foi aplicado um protocolo de pesquisa único a 1.465 pacientes brasileiros classificados como tendo EpA de acordo com os critérios do European Spondyloarthropaties Study Group (ESSG), atendidos em 29 centros de referência em reumatologia do Brasil. Foram registradas as variáveis clínicas e demográficas. A qualidade de vida foi analisada por meio do questionário Ankylosing Spondylitis Quality of Life (ASQoL). Resultados: A pontuação média do ASQoL foi de 7,74 (+ 5,39). Ao analisar doenças específicas no grupo de EpA, as pontuações do ASQoL não apresentaram diferença estatisticamente significativa. Os dados demográficos mostraram piores escores de ASQoL associados ao gênero feminino (p = 0,014) e etnia negra (p < 0,001). Quanto aos sintomas clínicos, a dor na região glútea (p = 0,032), a dor cervical (p < 0,001) e a dor no quadril (p = 0,001), estiveram estatisticamente associadas a piores escores no ASQoL. O uso contínuo de fármacos anti-inflamatórios não esteroides (p < 0,001) e agentes biológicos (p = 0,044) esteve associado a escores mais elevados de ASQoL, enquanto outros medicamentos não interferiram nos escores do ASQoL. Conclusão: Nesta grande série de pacientes com EpA, o sexo feminino e a etnia negra, bem como sintomas predominantemente axiais, estiveram associados a uma qualidade de vida reduzida.

Abstract Objective: To analyze quality of life and demographic and clinical variables associated to its impairment in a large Brazilian cohort of patients with spondyloarthritis (SpA). Methods: A common protocol of investigation was applied to 1465 Brazilian patients classified as SpA according to the European Spondyloarthropaties Study Group (ESSG) criteria, attended at 29 reference centers for Rheumatology in Brazil. Clinical and demographic variables were recorded. Quality of life was analyzed through the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results: The mean ASQoL score was 7.74 (± 5.39). When analyzing the specific diseases in the SpA group, the ASQoL scores did not present statistical significance. Demographic data showed worse scores of ASQoL associated with female gender (p = 0.014) and African-Brazilian ethnicity (p < 0.001). Regarding clinical symptoms, buttock pain (p = 0.032), cervical pain (p < 0.001) and hip pain (p = 0.001), were statistically associated with worse scores of ASQoL. Continuous use of nonsteroidal anti-inflammatory drugs (p < 0.001) and biologic agents (p = 0.044) were associated with higher scores of ASQoL, while the other medications did not interfere with the ASQoL scores. Conclusion: In this large series of patients with SpA, female gender and African-Brazilian ethnicity, as well as predominant axial symptoms, were associated with impaired quality of life.

Efeitos dos exercícios de alongamento muscular no tratamento da fibromialgia: uma revisão sistemática / Effects of muscle stretching exercises in the treatment of fibromyalgia: a systematic review

Objetivo: O presente trabalho tem como objetivo sistematizar evidências científicas sobre a utilização dos exercícios de alongamento muscular no tratamento da fibromialgia (FM). Metodologia: Foi realizado a partir de consulta retrospectiva, sem limite cronológico e linguístico, às bases de dados MedLine, LILACS, SciELO e PEDro, além da ferramenta de busca PubMed. A coleta foi realizada por dois revisores independentes, em outubro de 2012, sendo a estratégia de busca formulada por meio do cruzamento de descritores e termos relevantes para o tema nos idiomas inglês, português e espanhol. Foram incluídos ensaios clínicos randomizados (ECRs) compostos apenas por pacientes com diagnóstico clínico de FM e com exercícios de alongamento muscular como medida terapêutica em pelo menos um dos grupos de intervenção. Os estudos incluídos foram avaliados quanto à qualidade metodológica por meio da escala PEDro, e suas referências bibliográficas, analisadas, para se destacar fontes adicionais. A busca totalizou 6.794 artigos. Cinco artigos foram selecionados, sendo um deles excluído por apresentar baixa qualidade metodológica. A dor foi avaliada por unanimidade. O método e o tempo das intervenções variaram amplamente, houve falta de menção de parâmetros na utilização dos alongamentos e ausência de exames físicos específicos. Resultados: Houve melhora significativa em todos os estudos quanto à dor, além de aspectos relacionados a qualidade de vida e condição física. Conclusão: É evidente a importância do alongamento muscular no tratamento da FM, porém observa-se a necessidade de novos estudos para se estabelecer os reais benefícios da técnica, visto que a maioria dos trabalhos publicados apresenta baixa qualidade metodológica e ausência de padronização quanto ao uso desse recurso. .

Objective: this study has the objective to systematize scientific evidences about the use of muscle stretching exercises in the treatment of FM. Methodology: it was performed from retrospective research without chronological and linguistic limits, at databases of MEDLINE, LILACS, SciELO and PEDro, as well as at PubMed search tool. Data collection was performed by two independent reviewers in October 2012, with the search strategy formulated by crossing descriptors and relevant terms to the topic in English, Portuguese and Spanish languages. Randomized clinical trials, only with patients with a clinical diagnosis of fibromyalgia and muscle stretching exercises as a therapeutic measure at least in one of the intervention groups were included. Included studies were assessed for methodological quality using PEDro scale and their references analyzed to highlight additional sources. The search amounted to an average of 6,794 items. Only five articles were selected, one being excluded because of its low methodological quality. Pain was assessed unanimously. The method and timing of interventions varied widely, there was poor mention of the parameters used in the stretches and absence of specific physical examinations. Results: there was significant improvement in all studies regarding pain, besides as related to quality of life and physical condition. Conclusion: it is clear the importance of muscle stretching in the treatment of FM, however, there is a need for further studies to establish the real benefits of the technique, because the majority of published studies shows low methodological quality and there is a lack of standardization regarding the use of this resource. .

Avaliação do desempenho do BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) numa coorte brasileira de 1492 pacientes com espondiloartrites: dados do Registro Brasileiro de Espondiloartrites (RBE) / Evaluation of performance of BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) in a Brazilian cohort of 1492 patients with spondyloarthritis: data from the Brazilian Registry of Spondyloarthritides (RBE)

Objetivo Avaliar os resultados da aplicação do Índice de Atividade de Doença da Espondilite Anquilosante de Bath (BASDAI) numa série de pacientes brasileiros com EpA e estabelecer suas correlações com as variáveis específicas do grupo. Métodos Um protocolo comum de investigação foi prospectivamente aplicado em 1.492 pacientes brasileiros classificados como EpA pelos critérios do Grupo Europeu de Estudo das Espondiloartropatias (ESSG), acompanhados em 29 centros de referência em reumatologia no Brasil. Variáveis clínicas, demográficas e índices de doença foram colhidos. Os valores totais do BASDAI foram comparados com a presença das diferentes variáveis. Resultados O valor médio do BASDAI foi de 4,20 ± 2,38. Os escores médios do BASDAI foram mais elevados nos pacientes com forma clínica combinada, comparado às formas axiais e periféricas isoladas, nos pacientes do sexo feminino e nos sedentários. Com relação ao componente axial, valores mais altos do BASDAI estiveram significativamente associados à lombalgia inflamatória, à dor alternante em nádegas, à dor cervical e ao acometimento de coxofemorais. Houve associação estatística entre os valores do BASDAI e o comprometimento periférico, relacionado ao número de articulações inflamadas, tanto dos membros inferiores quanto dos membros superiores, e às entesites. A positividade do HLA-B27 e a presença de manifestações extra-articulares não estiveram correlacionadas com os valores médios do BASDAI. Valores mais baixos do BASDAI estiveram associados ao uso de agentes biológicos (p < 0,001). Conclusão Nesta série heterogênea de pacientes brasileiros com EpA, o BASDAI conseguiu demonstrar “atividade de doença” tanto nos pacientes com acometimento axial quanto naqueles com envolvimento periférico. .

Objective To analyze the results of the application of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in a large series of Brazilian patients with the diagnosis of SpA and establish its correlations with specific variables into the group. Methods A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyoarthropathies Study Group (ESSG), attended at 29 referral centers of Rheumatology in Brazil. Clinical and demographic variables, and disease indices (BASDAI, Basfi, Basri, Mases, ASQol) were applied. The total values of BASDAI were compared to the presence of the different variables. Results The mean score of BASDAI was 4.20 ± 2.38. The mean scores of BASDAI were higher in patients with the combined (axial + peripheral + entheseal) (4.54 ± 2.38) clinical presentation, compared to the pure axial (3.78 ± 2.27) or pure peripheral (4.00 ± 2.38) clinical presentations (P < 0.001). BASDAI also presented higher scores associated with the female gender (P < 0.001) and patients who did not practice exercises (P < 0.001). Regarding the axial component, higher values of BASDAI were significantly associated with inflammatory low back pain (P < 0.049), alternating buttock pain (P < 0.001), cervical pain (P < 0.001) and hip involvement (P < 0.001). There was also statistical association between BASDAI scores and the peripheral involvement, related to the lower (P = 0.004) and upper limbs (P = 0.025). The presence of enthesitis was also associated to higher scores of BASDAI (P = 0.040). Positive HLA-B27 and the presence of cutaneous psoriasis, inflammatory bowel disease, uveitis and urethritis were not correlated with the mean scores of BASDAI. Lower scores of BASDAI were associated with the use of biologic agents (P < 0.001). Conclusion In this heterogeneous Brazilian series of SpA patients, BASDAI was able to demonstrate “disease ...

Perfil epidemiológico da espondiloartrite de início juvenil comparada com a espondiloartrite de início na vida adulta em uma grande coorte brasileira / Epidemiologic profile of juvenile-onset compared to adult-onset spondyloarthritis in a large Brazilian cohort

Objetivo Analisar as características clínicas e epidemiológicas das espondiloartrites (EpA) de início juvenil (< 16 anos) e compará-las com um grupo de pacientes com EspA de início na vida adulta (≥ 16 anos). Pacientes e métodos Coorte prospectiva, observacional e multicêntrica com 1.424 pacientes com diagnóstico de EspA de acordo com o European Spondyloarthropathy Study Group (ESSG) submetidos a um protocolo comum de investigação e recrutados em 29 centros de referência participantes do Registro Brasileiro de Espondiloartrites (RBE). Os pacientes foram divididos em dois grupos: idade no início<16 anos (grupo EspAiJ) e idade no início ≥ 16 anos. Resultados Entre os 1.424 pacientes, 235 manifestaram o início da doença antes dos 16 anos (16,5%). As variáveis clínicas e epidemiológicas associadas com a EspAiJ foram: gênero masculino (p<0,001), artrite em membro inferior (p=0,001), entesite (p=0,008), uveíte anterior (p=0,041) e HLA-B27 positivo (p=0,017), em associação com escores mais baixos de atividade da doença (Bath Ankylosing Spondylitis Disease Activity Index – BASDAI; p=0,007) e de capacidade funcional (Bath Ankylosing Spondylitis Functional Index – BASFI; p=0,036). A psoríase cutânea (p<0,001), a doença inflamatória intestinal (p=0,023), a dactilite (p=0,024) e o envolvimento ungueal (p=0,004) foram mais frequentes em pacientes com EspA de início na vida adulta. Conclusões Nessa grande coorte brasileira, os pacientes com EspAiJ se caracterizavam predominantemente pelo gênero masculino, envolvimento periférico (artrite e entesite), HLA-B27 positivo e escores de doença mais baixos. .

Objective To analyze the clinical and epidemiologic characteristics of juvenile-onset spondyloarthritis (SpA) (< 16 years) and compare them with a group of adult-onset (≥ 16 years) SpA patients. Patients and methods Prospective, observational and multicentric cohort with 1,424 patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group (ESSG) submitted to a common protocol of investigation and recruited in 29 reference centers participants of the Brazilian Registry of Spondyloarthritis (RBE – Registro Brasileiro de Espondiloartrites). Patients were divided in two groups: age at onset<16 years (JOSpA group) and age at onset ≥ 16 years (AOSpA group). Results Among the 1,424 patients, 235 presented disease onset before 16 years (16.5%). The clinical and epidemiologic variables associated with JOSpA were male gender (p<0.001), lower limb arthritis (p=0.001), enthesitis (p=0.008), anterior uveitis (p=0.041) and positive HLA-B27 (p=0.017), associated with lower scores of disease activity (Bath Ankylosing Spondylitis Disease Activity Index – BASDAI; p=0.007) and functionality (Bath Ankylosing Spondylitis Functional Index – BASFI; p=0.036). Cutaneous psoriasis (p<0.001), inflammatory bowel disease (p=0.023), dactylitis (p=0.024) and nail involvement (p=0.004) were more frequent in patients with adult-onset SpA. Conclusions Patients with JOSpA in this large Brazilian cohort were characterized predominantly by male gender, peripheral involvement (arthritis and enthesitis), positive HLA-B27 and lower disease scores. .
