An investigation about chronic prostatitis in ankylosing spondylitis

Abstract Background: Chronic prostatitis has been a common disease reported with high frequency in ankylosing spondylitis (AS) even from decades ago. Infectious (Chlamydia trachomatis) or non-infectious (uric acid) prostatitis can hypothetically trigger vertebral inflammation in AS. This study aimed to assess the features of chronic prostatitis in patients with AS compared to healthy controls. Methods: A cross-sectional study including male patients with AS and healthy controls who agreed to undergo a prostate examination was conducted. Structured clinical interviews, prostate physical examinations, and cytological, biochemical, and microbiological tests on urinary samples collected before and after standardized prostatic massage (pre- and post-massage test) were performed. Results: Ninety participants (45 AS patients, mean age: 52.5 ± 10.0 years, with longstanding disease, 12.4 ± 6.9years, and 45 controls, mean age: 52.8 ± 12.1 years) were included. National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) scores were similar in the AS and control groups (4.0 [1.0-12.0] vs. 5.0 [1.0—8.5], p = 0.994). The frequencies of symptoms of chronic prostatitis (NIH-CPSI Pain Domain ≥4) were also similar in both groups (23.3% vs. 22.7%, p = 0.953). Results of polymerase chain reaction tests for Chlamydia trachomatis were negative in all tested urinary samples, and uric acid concentrations and leukocyte counts were similar in all pre- and post-massage urinary samples. Conclusions: In this study, chronic prostatitis occurred in male patients with AS, but its frequency and characteristics did not differ from those found in the healthy male population of similar age.

Medical schools in Brasil: population, economic and historical analysis

SUMMARY BACKGROUND To describe the current distribution and historical evolution of undergraduate courses in medicine in Brasil. METHODS Analytical cross-sectional study of secondary data. Through the Ministry of Education, the data of the medical courses were obtained, and through the Brazilian Institute of Geography and Statistics, the population and economic data of the Brazilian states were obtained. RESULTS In Brasil, there were 298 medical courses (1,42 courses / million inhabitants) in January 2018, totaling 31,126 vacancies per year, with 9,217 gratuitous vacancies (29.6%) and 17,963 vacancies in the hinterland (57, 7%). In Brazilian states, there are positive and statistically significant (p <0.001) correlations of the variables: "vacancies" and "population" (R 0.92); "vacancies" and "gross domestic product" ("GDP") (R 0.83); "percentage of vacancies in the hinterland" and "population in the hinterland" (R 0.71) and "percentage of vacancies in the hinterland" and "GDP" (R 0.64). There was a negative and statistically significant correlation between "gratuitous vacancy percentage" and "GDP" (R -0.54, p = 0.003). More paid courses than gratuitous courses and more courses in the hinterland than in the capitals have been created since 1964, in proportions that have remained similar since then, but in higher numbers since 2002. CONCLUSIONS The distribution of medical courses in Brasil correlates with the population and economical production of each state. The expansion of Brazilian medical education, which has been accelerated since 2002, is based mainly on paid courses in the hinterland, in the same pattern since 1964.

RESUMO OBJETIVO Descrever a distribuição e evolução histórica das vagas em cursos de graduação em medicina no Brasil. MÉTODOS Estudo transversal analítico de dados secundários. No Ministério da Educação obtiveram-se dados dos cursos de medicina e no Instituto Brasileiro de Geografia e Estatística foram obtidos dados populacionais e econômicos dos estados. RESULTADOS Havia no Brasil, até janeiro de 2018, 298 cursos de medicina (1,42 curso/milhão de habitantes), totalizando 31.126 vagas anuais, com 9.217 vagas gratuitas (29,6%) e 17.963 vagas no interior do País (57,7%). Nos estados há correlações positivas e significativas (p<0,001) das variáveis: "vagas em medicina" e "população" (R 0,92); "vagas em medicina" e "produto interno bruto" ("PIB") (R 0,83); "percentual de vagas em medicina no interior" e "população no interior" (R 0,71) e "percentual de vagas em medicina no interior" e "PIB" (R 0,64). Há correlação negativa e significativa entre "percentual de vagas gratuitas" e "PIB" (R -0,54, p=0,003). Passaram a ser criados mais cursos pagos do que gratuitos e mais cursos no interior do que nas capitais a partir de 1964 (p <0,001), e a relação curso/milhão de habitantes aumentou a partir de 2002 (p<0,001). CONCLUSÕES A distribuição de vagas em cursos de medicina no Brasil correlaciona-se à população e à produção econômica de cada estado. A expansão do ensino médico brasileiro, acelerada além do crescimento populacional a partir de 2002, é baseada principalmente em cursos pagos no interior dos estados brasileiros, característica inalterada desde 1964.

Validity of fibromyalgia survey questionnaire (2016) assessed by telephone interview and cross-cultural adaptation to Brazilian Portuguese language

Abstract Background: To verify the validity of the 2016-revised Fibromyalgia Survey Questionnaire (FSQ) by telephone interview compared to self-administration and to produce a valid version of FSQ in Brazilian Portuguese language. Methods: The Brazilian version of FSQ was produced following the recommendations for cross-cultural adaptation. Validity of Brazilian FSQ self-administration was assessed by checking agreement of its results with fibromyalgia diagnosis according the 1990 American College of Rheumatology (ACR) criteria. Reproducibility and validity of FSQ by telephone were assessed by comparing its results with the previous FSQ self-administration. Results: A Brazilian Portuguese version (FSQ-Brazil) was produced. FSQ-Brazil had good internal consistency (Cronbach's alpha between 0.73 and 0.94). Agreement between the results obtained by self-administration of FSQ-Brazil and by telephone interview was substantial or almost perfect for almost all questions about pain sites and all questions about other somatic symptoms (Cohen's kappa higher than 0.6). There were small but significant bias toward higher scores of widespread pain index and fibromyalgia severity scale in the telephone interview compared to self-administration. Fibromyalgia definition by self-administration and telephone interview with FSQ-Brazil both revealed substantial agreement with the diagnosis based on ACR 1990 criteria (Cohen's kappa 0.62 and 0.65; respectively). Conclusions: FSQ-Brazil demonstrated good internal consistency, reproducibility and validity both by self-administration and by telephone interview. However, caution must be taken with the interpretation of quantitative scores of widespread pain index and symptoms severity scale, which slightly differed according the method (self-administration or interview) in our study.(AU)

Determinants of quality of life in Paget's disease of bone / Determinantes da qualidade de vida na doença de Paget óssea

Abstract Objective: To evaluate the parameters associated with quality of life in patients with Paget's disease of bone. Methods: Patients with Paget's disease of bone were evaluated with SF-36 and WHOQOL-bref questionnaires. Patients with other diseases that could cause significant impairment of their quality of life were excluded. We searched for correlations between the results and: age, time from diagnosis, type of involvement, pain related to Paget's disease of bone, limitation to daily activities, deformities, bone specific alkaline phosphatase, the extent of involvement and treatment. Results: Fifty patients were included. Results of the SF-36 total score and its domains, physical and mental health, were significantly correlated with bone pain and deformities. Marital status was significantly correlated with the SF-36 total score and Mental Health Domain. BAP levels and disease extension were significantly correlated to SF-36 Physical Health Domain. After multivariate analysis, the only parameters that remained significantly associated with the SF-36 total score and to its Mental Health and Physical Health Domains were pain and marital status.The WHOQOL-bref total score was significantly associated with pain, physical impairment and deformities. WHOQOL-bref Domain 1 (physical) score was significantly associated with marital status, pain and deformities, while Domain 2 (psychological) score was associated with marital status, physical impairment and kind of involvement. After multivariate analysis, the presence of pain, deformities, and marital status were significantly associated with results of the WHOQOL-bref total score and its Domain 1. WHOQOL-bref domain 2 results were significantly predicted by pain and marital status. Conclusion: The main disease-related factor associated with SF-36 results in Paget's disease of bone patients was bone pain, while bone pain and deformities were associated with WHOQOL-bref.

Resumo Objetivo: Avaliar os parâmetros associados à qualidade de vida em pacientes com doença de Paget óssea (DPO). Métodos: Avaliaram-se pacientes com DPO com os questionários SF-36 e WHOQOL-bref. Excluíram-se pacientes com outras doenças que pudessem causar comprometimento significativo da qualidade de vida. Buscou-se por correlações entre os resultados e idade, tempo de diagnóstico, tipo de envolvimento, dor relacionada com a DPO, limitação às atividades diárias, deformidades, fosfatase alcalina específica do osso, extensão do envolvimento e tratamento. Resultados: Incluíram-se 50 pacientes. Os resultados da pontuação total do SF-36 e seus domínios, saúde física e saúde mental, se correlacionaram significativamente com a dor óssea e deformidades. O estado civil se correlacionou significativamente com a pontuação total do SF-36 e com seu domínio saúde mental. Os níveis de BAP e a extensão da doença se correlacionaram significativamente com o domínio saúde física do SF-36. Depois da análise multivariada, os únicos parâmetros que permaneceram significativamente associados à pontuação total do SF-36 e aos seus domínios saúde mental e saúde física foram a dor e o estado civil. A pontuação total do WHOQOL-bref esteve significativamente associada à dor, ao comprometimento físico e a deformidades. O escore do Domínio 1 (físico) do WHOQOL-bref esteve significativamente associado ao estado civil, dor e deformidades, enquanto o Domínio 2 (psicológico) esteve associado ao estado civil, comprometimento físico e tipo de envolvimento. Depois da análise multivariada, a presença de dor, deformidades e estado civil esteve significativamente associada à pontuação total do WHOQOL-bref e à pontuação do seu Domínio 1. Os resultados do WHOQOL-bref 2 foram significativamente preditos pela dor e pelo estado civil. Conclusão: O principal fator associado aos escores do SF-36 foi a dor óssea, enquanto a dor óssea e as deformidades estiveram associadas ao WHOQOL-bref.

Cultural Adaptation of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) - to Brazilian Spoken Portuguese: NIH-CPSI (Braz)

Objectives To create a Brazilian version of the National Institutes of Health – Chronic Prostatitis Symptom Index (NIH-CPSI) using a cross-cultural adaptation process. Materials and Methods The nine items of the NIH-CPSI were translated to Portuguese, by two independent translators, of native Portuguese language origin, and it was obtained a single version, that was retranslated to English by two English native spoken translators, in order to correct any discrepancies. Those versions were compared to the original text, the modifications were applied and it was created a final version in Portuguese. That was pre-tested and applied to 30 patients with pain or perineal or ejaculatory disorder. To each item of the pre-final version it was assigned a score according to the grade of understanding and clarity in order to implement the adequate corrections. The final version in Portuguese was submitted to evaluations including face validation and psychometric proprieties of reproducibility and internal consistency, respectively evaluated by the (p) Pearson correlation coefficient and α Cronbach coefficient. Results All items applied to 30 patients during pre-test phase had a grade higher than 8 of understanding and clarity, and were considered clearly understandable by the patients. However, at face validation evaluation, there was an inconsistency of item three that was redone. The final produced version, called NIH-CPSI (Braz) showed good reproducibility (p = 0.89-0.99) and internal consistency (α Cronbach coefficient = 0.85-0.93). Conclusions NIH-CPSI was adapted to Brazilian spoken Portuguese and its original proprieties were maintained, being a valid instrument for evaluations of symptoms of chronic prostatitis in Brazilian patients. .

Lesões destrutivas da linha média induzidas por cocaína com ANCA positivo mimetizando a granulomatose de Wegener / Cocaine-induced midline destruction lesions with positive ANCA test mimicking Wegener's granulomatosis

O uso crônico de cocaína por inalação pode causar lesões destrutivas de linha média (LDLMIC), que podem ser difíceis de distinguir das lesões da granulomatose de Wegener (GW) nos ouvidos, nariz e garganta. Descrevemos o caso de uma paciente de 43 anos admitida com história de dois anos de obstrução nasal e rinorreia. Ela havia recebido o diagnóstico de GW há cinco meses e estava em tratamento com prednisona e ciclofosfamida. Ao exame físico apresentava perfuração de septo nasal e palato. Exames de laboratório mostraram elevação das proteínas de fase aguda e teste p-ANCA positivo. Ensaios ELISA antiproteinase 3 e mieloperoxidase foram negativos. Tomografia computadorizada (TC) dos seios paranasais mostrou destruição de septo nasal e palato, bem como sinusite maxilar bilateral. TC de tórax resultou normal. Biópsia da mucosa nasal revelou infiltrado inflamatório sem granuloma ou vasculite. Quando questionada, admitiu ser usuária de cocaína há cinco anos. Os imunossupressores foram suspensos e a paciente não mais fez uso da droga. Ela está sendo monitorada há seis meses e não desenvolveu novas lesões ou sintomas de outros órgãos. O diagnóstico diferencial em pacientes com LDLMIC pode ser desafiador. A avaliação deve incluir pesquisa de uso intranasal de cocaína. Embora o teste de ANCA não diferencie claramente o ANCA encontrado em alguns pacientes com LDLMIC daqueles em pacientes com GW, o envolvimento localizado e os achados de biópsia não típicos de vasculite granulomatosa de pequenos vasos devem ser reconhecidos como características das lesões induzidas por cocaína.

Chronic use of cocaine by inhalation may induce midline destructive lesions (CIMDL), which can sometimes be difficult to distinguish from the ear, nose and throat lesions of Wegener's Granulomatosis (WG). We describe the case of a 43-year-old female patient admitted with a two-year history of nasal obstruction and rhinorrhea. She had been diagnosed with WG for five months, being on prednisone and cyclophosphamide. On her physical examination, perforation of her nasal septum and palate was observed. Laboratory tests showed elevated acute phase proteins and a positive p-ANCA test. ELISA assays anti-proteinase 3 and myeloperoxidase were negative. The paranasal sinus computed tomography (CT) showed destruction of the nasal septum and palate, in addition to bilateral maxillary sinusitis. Chest CT was normal. Nasal mucosal biopsy revealed an inflammatory infiltrate, with neither granuloma nor vasculitis. When questioned, she admitted being a cocaine user for five years. Medical therapy and cocaine use were withdrawn. She has been followed up for six months and no other lesion or other organ symptoms occurred. Differential diagnosis in patients with midline destructive lesions can be very challenging. Evaluation should include enquiry about intranasal use of cocaine. Although ANCA testing does not clearly differentiate the ANCA found in some patients with CIMDL from those found in WG patients, the localized involvement and the biopsy findings non-characteristic of small vessel granulomatous vasculitis should be recognized as features for cocaine-induced lesions.

Mielopatia torácica por calcificação do ligamento amarelo cursando com hiperproteinorraquia e resposta à corticoterapia: relato de caso / Thoracic myelopathy due to calcification of the ligamentum flavum with hyperproteinorachia and responsive to steroid therapy: case report

Calcificação e ossificação do ligamento amarelo ou do ligamento longitudinal posterior são causas de mielopatia compressiva, mais frequentes nos níveis torácicos inferiores e bastante raras em populações ocidentais. A descompressão cirúrgica é a única terapia proposta, mas a doença costuma ser progressiva e sua recorrência após a cirurgia não é incomum. Mediadores inflamatórios podem ter algum papel na progressão da mielopatia compressiva, mas não se tem notícia de qualquer proposta de abordagem terapêutica envolvendo agentes anti-inflamatórios. Neste contexto, relatamos um caso de mielopatia compressiva por calcificação do ligamento amarelo em que se observou hiperproteinorraquia e resposta à corticoterapia. Tais informações são inéditas e podem fornecer novas ideias para a compreensão da doença.

Calcification and ossification of the ligamentum flavum or of the posterior longitudinal ligament are causes of compressive myelopathy, more frequent in the lower thoracic levels, and extremely rare in Western populations. Surgical decompression is the only therapy, but the disease is usually progressive, and its recurrence after surgery is common. Inflammatory mediators might play a role in the progression of compressive myelopathy, but, to our knowledge, the therapeutic approach involving anti-inflammatory agents has never been tried before. We report a case of compressive myelopathy due to calcification of the ligamentum flavum, in which hyperproteinorachia and response to steroid therapy have been observed. Those data have not been published before and might provide new ideas for the disease understanding.

Micofenolato mofetil na síndrome de Sjögren primária: uma opção para o tratamento da agranulocitose / Mycophenolate mofetil in primary Sjögren's syndrome: a treatment option for agranulocytosis

A síndrome de Sjögren (SS) é uma doença autoimune caracterizada pela presença de infiltrado linfocítico nas glândulas salivares e lacrimais. Manifestações hematológicas da síndrome de Sjögren primária (SSp) geralmente consistem em anemia leve, trombocitopenia, neutropenia moderada e linfopenia. Agranulocitose é raramente descrita e, em geral, responde bem ao tratamento de imunossupressão. Neste trabalho, descrevemos o caso de uma paciente portadora de SSp que apresentou quadro de agranulocitose refratária ao tratamento. A biópsia de medula revelou medula óssea hipocelular com maturação normal da série granulocítica. A paciente foi sucessivamente tratada com prednisona em altas doses, fator estimulador de colônia de macrófagos e ciclosporina, todos sem resposta hematológica. Micofenolato mofetil (MMF) foi iniciado, e após dois meses houve aumento na contagem das células brancas. Após um ano de seguimento a paciente não apresentou novos episódios de neutropenia, nem complicações infecciosas. Concluímos que, na agranulocitose refratária associada à SSp, o tratamento com MMF pode ser uma opção eficaz e bem tolerada.

The Sjögren's syndrome (SS) is an autoimmune disease characterized by a lymphocytic infiltration of salivary and lacrimal glands. Hematological manifestations of primary SS (pSS) usually consist of mild anemia, thrombocytopenia, moderate neutropenia, and lymphopenia. Agranulocytosis is rarely reported and usually responds to immunosuppression. We report the case of a pSS patient who presented with refractory agranulocytosis. Bone marrow biopsy disclosed a hypocellular bone marrow with normal maturation of the granulocytic series. The patient was successively treated with high-dose prednisone, granulocyte-macrophage colony stimulation factor, and cyclosporine, with no hematological response. Mycophenolate mofetil (MMF) was initiated and after two months there was a rise on the white blood cell count. After one year of follow-up, she had neither further neutropenia episodes, nor infectious complications. We conclude that, in pSS refractory agranulocytosis, MMF can be an effective and well-tolerated treatment option.

Avaliação do sistema musculoesquelético na unidade de emergência / Musculoskeletal system assessment in an emergency room

OBJETIVO: As condições musculoesqueléticas possuem um enorme e crescente impacto no mundo. A despeito disso, alguns médicos não estão confiantes em suas próprias habilidades para a realização do exame clínico musculoesquelético. Este estudo teve como objetivo avaliar a prevalência dos sintomas musculoesqueléticos em uma unidade de emergência e a frequência de descrição do exame físico musculoesquelético nesses casos. MÉTODOS: Trata-se de estudo transversal. Foi realizada uma análise sistemática das fichas de atendimento na unidade de emergência do hospital da Universidade Federal de Santa Catarina, Brasil, de 24 a 30 de abril de 2009. RESULTADOS:Foram analisadas 392 fichas de atendimento, onde 41,5 por cento dos pacientes eram do sexo masculino e a idade média de 38,7 ± 17,2 anos. Sessenta e nove dos 392 pacientes (17,6 por cento) apresentaram-se com queixa musculoesquelética. A queixa musculoesquelética mais comum foi lombalgia (33/69). Somente 49,2 por cento dos pacientes que apresentavam distúrbios musculoesqueléticos como queixa principal tiveram exame físico específico descrito nas fichas. Pacientes com queixas musculoesqueléticas tiveram menor frequência de registro de exame abdominal (46 por cento versus 62 por cento, P = 0,01) e sinais vitais (46 por cento versus 66 por cento, P = 0,00), porém maior frequência de registro do exame musculoesquelético (49 por cento versus 0,6 por cento, P = 0,00). CONCLUSÕES:Este estudo confirma outras observações em todo o mundo. Queixas musculoesqueléticas são frequentes em uma unidade de emergência e, apesar disso, sugere-se que os sintomas musculoesqueléticos são insuficientemente avaliados, o que pode estar relacionado a uma educação médica insuficiente. É fundamental que escolas médicas coloquem maior ênfase nessas condições para que jovens médicos estejam mais preparados para lidar com essas doenças comuns.

OBJECTIVE: Musculoskeletal conditions have an enormous and growing impact worldwide. In spite of that, some clinicians are not confident in their own musculoskeletal examination skills. This study aimed to evaluate the prevalence of musculoskeletal symptoms in an emergency room, and the frequency of musculoskeletal physical examination description on those cases. METHODS: This was a cross-sectional study. We performed a systematic analysis of medical files at the emergency room of the University Hospital of the Federal University of Santa Catarina, Brazil, from April 24th to 30th, 2009. RESULTS: We analyzed 392 files, where 41.5 percent of patients were male and mean age was 38.7 ± 17.2 years-old. Sixty nine out of 392 patients (17.6 percent) presented with a musculoskeletal complaint. The most common musculoskeletal complaint was low back pain (33/69). Only 49.2 percent of patients with a musculoskeletal chief complaint had a specific physical examination registered on the files. Patients with musculoskeletal complaints had lower registrations of abdominal examination (46 percent versus 62 percent, P = 0.01) and vital signs (46 percent versus 66 percent, P = 0.002), but a higher frequency of musculoskeletal examination registration (49 percent versus 0.6 percent, P = 0.00). CONCLUSIONS: Our study confirms other observations worldwide. Musculoskeletal complaints are frequent in a emergency room setting and in spite of that it is suggested that musculoskeletal symptoms are poorly evaluated, which is probably related to an insufficient musculoskeletal education. It is essential that medical schools place more emphasis on these conditions so that young physicians will be more prepared to deal with these common diseases.

Toxicidade hepática é rara em pacientes com artrite reumatoide usando terapia combinada de leflunomida e metotrexato / Liver toxicity is rare in rheumatoid arthritis patients using combination therapy with leflunomide and methotrexate

OBJETIVO: De acordo com alguns estudos, a associação de leflunomida (LEF) a pacientes portadores de artrite reumatoide não responsivos a metotrexato (MTX) aumentou a eficácia do tratamento, elevando, porém, o risco de toxicidade hepática. Este estudo objetiva avaliar a incidência de toxicidade hepática no tratamento da artrite reumatoide ativa usando terapia combinada de LEF e MTX em comparação com monoterapia com MTX. MÉTODOS: Entre fevereiro e setembro de 2009, foram arrolados 97 pacientes consecutivos acompanhados pelo Hospital Universitário da Universidade Federal de Santa Catarina, Brasil. Pacientes com artrite reumatoide em uso de MTX somente ou em combinação com LEF tiveram seus prontuários sistematicamente revisados. As enzimas alanino/aspartato aminotransferases foram analisadas retrospectivamente desde o tratamento com MTX ou MTX mais LEF. Hepatotoxicidade foi definida como um aumento das enzimas hepáticas acima de duas vezes o limite superior da normalidade. RESULTADOS: 71 pacientes foram incluídos no estudo: 36,6 por cento usavam 20-25 mg/semana de MTX e 63,4 por cento usavam 20-25 mg/semana de MTX associado a 20 mg/ dia de LEF. Dos pacientes em terapia combinada, 11,1 por cento tinham níveis anormais das enzimas hepáticas versus 11,5 por cento daqueles em monoterapia (P = 1,0). Níveis anormais de aminotransferases têm sido observados em pacientes com artrite reumatoide tanto em monoterapia com MTX quanto com LEF. Em nosso estudo, não encontramos diferença entre as percentagens de elevação das aminotransferases em pacientes tratados somente com MTX ou com terapia combinada. CONCLUSÃO: A combinação de MTX e LEF em pacientes com artrite reumatoide é geralmente segura e bem tolerada.

OBJECTIVE: Some studies have reported that adding leflunomide (LEF) to the treatment of rheumatoid arthritis (RA) in patients who do not respond to methotrexate (MTX) improved efficacy but increased the risk of liver toxicity. This study aimed at assessing the incidence of liver toxicity in patients with active RA using the LEF and MTX combination therapy in comparison with that of patients on MTX monotherapy. METHODS: Between February and September 2009, 97 consecutive patients followed up at the University Hospital of the Universidade Federal de Santa Catarina, Brazil, were enrolled. RA patients on MTX alone or using the LEF and MTX combination had their medical records systematically reviewed. The alanine/aspartate aminotransferase enzymes were retrospectively analyzed since the beginning of treatment with MTX or MTX plus LEF. Hepatotoxicity was defined as an increase of at least two-fold the upper limits of normal of the liver enzymes. RESULTS: 71 RA patients were included in the study: 36.6 percent were using 20-25 mg/week of MTX alone and 63.4 percent were using 20-25 mg/week of MTX plus 20 mg/day of LEF. Of the patients on the combination therapy, 11.1 percent had abnormal levels of liver enzymes versus 11.5 percent of the patients on monotherapy (P = 1.0). Abnormal aminotransferase levels have been seen with both MTX and LEF monotherapies in patients with RA. In our study, no difference was found between the percentages of aminotransferase elevations of patients being treated with MTX alone or in combination with LEF. CONCLUSION: The combination of MTX and LEF in RA patients is generally safe and well tolerated.

Arterite de Takayasu: tratamento com anti-TNF em uma casuística brasileira / Takayasu arteritis: anti-TNF therapy in a Brazilian setting

O objetivo deste estudo é descrever as características clínicas e as respostas às intervenções terapêuticas, incluindo a terapia antifator de necrose tumoral (TNF), em uma série de casos brasileiros de arterite de Takayasu (AT). Foi realizado um estudo observacional, retrospectivo, com base na revisão de prontuários, incluindo todos os pacientes com AT, de acordo com os critérios de classificação do American College of Rheumatology, em acompanhamento no Serviço de Reumatologia do Hospital Universitário da Universidade Federal de Santa Catarina (UFSC), Brasil. Foram incluídos 15 pacientes, sendo 14 (93,3 por cento) mulheres, com idade média ao diagnóstico de 29,6 anos. Hipertensão arterial sistêmica (60,0 por cento) e ausência de pulsos em membros superiores (53,3 por cento) foram os achados clínicos mais comuns ao diagnóstico. As artérias subclávias e carotídeas foram os vasos mais frequentemente acometidos. Doze pacientes (80,0 por cento) não obtiveram remissão sustentada em terapia isolada com corticosteroide, tendo sido empregada terapia imunossupressora, sendo metotrexato, azatioprina e ciclofosfamida as drogas utilizadas. Intervenções cirúrgicas foram necessárias em 53,3 por cento dos casos. Três casos (20,0 por cento) foram refratários à terapia com corticoides e imunossupressores e foram tratados com agentes anti-TNF, com subsequente remissão da doença. Em conclusão, observou-se que uma parcela importante dos casos de AT é refratária à terapia tradicional e os agentes anti-TNF podem representar uma opção promissora para o controle da doença nesses casos.

The aim of this study was to describe clinical features and response to different therapeutic interventions, including anti-tumor necrosis factor (TNF) agents, in a case series of Takayasu arteritis (TA) from Brazil. A retrospective observational chart-review study was performed including all patients meeting the American College of Rheumatology TA classification criteria followed at the rheumatology outpatient clinic of a Brazilian university hospital. Fifteen patients were included, of which 14 (93.3 percent) were females, with a mean age of 29.6 years at diagnosis. Systemic hypertension (60.0 percent) and abolished upper limb pulses (53.3 percent) were the most common clinical features at the diagnosis. Subclavian and carotid arteries were the most commonly affected vessels. Twelve patients (80.0 percent) did not achieve sustained remission on therapy with corticosteroids alone and received immunosuppressive agents including methotrexate, azathioprine and cyclophosphamide. Surgical intervention was necessary and performed in 53.3 percent of cases. Three cases (20.0 percent) were refractory to corticosteroid plus diverse immunosuppressive therapy and were treated with anti-TNF agents, all of them with disease remission. In conclusion, a significant proportion of TA cases are refractory to traditional therapy. The use of anti-TNF agents may become a possible therapy for these patients.
