Background: At the beginning of the coronavirus disease (COVID-19) pandemic, hydroxychloroquine (HCQ) was widely used as a possible antiviral agent. Current knowledge indicates that HCQ has little or no effect on individual clinical outcomes of COVID-19, but populational effects on disease transmissibility are still unknown. Objective: This study investigates the hypothesis that massive HCQ consumption by a population may contribute to reducing the transmissibility of SARS-CoV-2 and COVID-19 spread by reducing the viral load of infected individuals. Methods: Public database of seven states from Brazil in 2020 were assessed, before the start of COVID-19 vaccination. The daily values of the COVID-19 effective reproduction number (Rt) were obtained. Associations between Rt values and the proposed predictor variables (prevalence of COVID-19 as a marker of collective immunity; social isolation indices; consumption of HCQ) were tested using multiple linear regression analysis. Results: In all seven states, consumption of HCQ was a significant negative predictor of Rt (β ranged from -0.295 to -0.502, p = 0.001). Furthermore, the mean derivative of Rt during the declining period of the COVID-19 incidence (the mean rate of variation) was also significantly negatively related to the mean HCQ consumption in that period (R2 = 0.895; β = -0.783; p = 0.011), meaning that the higher the HCQ consumption, the faster the decline of COVID-19 Rt. It suggests a dose-response phenomenon and a causal relationship in this association. Conclusion: The results of this study are compatible with the hypothesis that HCQ has small but significant in vivo antiviral effects that are able to reduce SARS-CoV-2 transmissibility at the populational level.

Objective To synthesize available evidence about diagnostic accuracy of clinical tests and imaging examinations for femoroacetabular impingement (FAI) syndrome. Design Umbrella review. Setting N/A. Participants N/A. Interventions N/A. Main outcome measures Systematic reviews (SR) indexed in Embase, LIVIVO, PubMed, SCOPUS, the Cochrane Library, and Web of Science were searched in a 2-phase process. SR assessing diagnostic accuracy were considered eligible. Results From 1520 studies, 6 SR were included, which evaluated 24 primary studies related to FAI syndrome. Of these, 5 SR assessed clinical tests, and a substantial heterogeneity was found concerning reference standards adopted across primary studies, which included arthroscopy, clinical examination (associated or not with imaging exams), intra-articular injections, and open surgery. Most clinical tests presented higher values of sensitivity compared with specificity, although evidence was considered limited because the same primary studies were often included across SR. Nonetheless, evidence around the flexion adduction internal rotation (FADIR) test was considered stronger and its use as a screening tool was consistently supported. Only one SR assessed the accuracy of imaging examinations, which adopted open surgery as the sole reference standard. Most imaging exams presented considerably high values of sensitivity, although specificity values were notably lower. Conclusions No robust recommendations can be provided for most clinical tests, although the FADIR test, in particular, was consistently supported as a screening tool. Moreover, although imaging examinations showed considerably high sensitivity values, evidence was considered sparse and further research is strongly recommended to validate its use as reference standards for diagnostic accuracy data.

Background Hip osteoarthritis is one of the major causes of disability worldwide, and although total hip arthroplasty is considered effective in the management of this condition, its effects on postural balance remain unclear. Research Question What are the effects of total hip arthroplasty for primary hip osteoarthritis on the postural balance compared to preoperative status and/or to healthy controls?. Method A systematic review was conducted, and the Embase, Latin American and Caribbean Health Sciences (LILACS), PubMed, Scopus, The Cochrane Library, and Web of Science databases were searched. Randomized and non-randomized studies were considered eligible for inclusion. The risk of bias of included studies was assessed using the Joanna Briggs Institute critical appraisal tools. Results Among the 41 potentially eligible studies, 13 studies were included for qualitative synthesis—8 studies had low risk of bias and 5 had moderate risk of bias. Ten studies compared the effects of total hip arthroplasty on the postural balance in healthy controls. Meanwhile, the remaining 3 studies compared such effects to the preoperative status only. Comparable results on the postural balance between the intervention and control groups were observed in 5 studies, whereas 3 studies showed better scores among healthy controls. The other 2 studies reported that postural balance could still be impaired at 6 months to 3 years postoperatively. All 3 studies with no healthy controls reported an improvement in the postural balance compared to the preoperative status. Conclusions Major post-surgical improvements were consistently observed compared to preoperative status, although postural balance impairment was still noted compared to healthy controls. Significance The results of this study might be a useful guide for clinicians on the extent of the therapeutic effects of hip arthroplasty on postural balance. Furthermore, the standardization of balance assessment tools could strengthen the certainty of cumulative evidence in future studies.

ABSTRACT Purpose Cross-cultural adaptation to Brazilian Portuguese and evaluation of content validity of a patient decision aid to help in choosing the feeding route for patients with severe dementia entitled “Making Choices: Feeding Options for Patients with Dementia”. Methods The cross-cultural adaptation involved two independent translations, synthesis of translations, two independent back-translations, their synthesis, and pretest with 30 caregivers. Content validation was based on analyzes of 35 Brazilian specialists (physicians, speech-language therapists and nurses experienced in caring for patients with severe dementia) through measures of content validity index and concordance between multiple judges by Fleiss’ kappa. Results The level of comprehension of the instrument by caregivers in the pretest was almost perfect. The specialists committee considered the contents of the instrument valid, in a statistically significant way. Conclusion The patient decision aid in Brazilian Portuguese entitled “Fazendo escolhas: opções de alimentação para pacientes com demência” obtained evidence of cross-cultural equivalence and content validity for use in the Brazilian population. Further studies are needed to assess its effects on the decision-making process in our population.

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

Objectives: To evaluate whether the use of a support tool for shared decision-making in the choice of feeding method for patients with severe dementia can benefit the patient/caregiver dyad, and to evaluate the quality of the decision-making process. Method: A search was performed in the Medline, LILACS, IBECS, SciELO, WHOLIS databases for randomized controlled trials, whether double-blind or otherwise, and quasi-experimental, cohort, case-control, or cross-sectional observational studies in Portuguese, Spanish, English and French. Results: Eight articles were found that showed that the use of a decision support tool, as an aid for the shared decision-making method, is beneficial as it reduces decisional conflict and increases the knowledge of caregivers about the subject. The quality of the decision-making process is unsatisfactory due to the low frequency of discussions between caregivers and the health team and the poor evaluation of caregivers about the participation of the team in the decision-making process. Conclusion: Decision support tools provide benefits for caregivers/patients undergoing the difficult task of deciding about feeding methods. Findings suggest that the current quality of decision-making is inadequate. Resumo Objetivos: Avaliar se o uso de instrumento de apoio para decisão compartilhada na escolha da via de alimentação em pacientes com demência em estágio grave traz benefício para a díade paciente/cuidador e avaliar a qualidade do processo decisório. Método: Busca nas bases de dados Medline, LILACS, IBECS, SciELO, WHOLIS por ensaios clínicos randomizados duplo cegos ou não, estudos quase-experimentais, observacionais de coorte, caso-controle ou transversais nos idiomas português, espanhol, inglês e francês. Resultados: Obtidos oito artigos que mostraram que o uso de apoio à decisão como método auxiliar de decisão compartilhada traz benefício, pois reduz o conflito decisional e aumenta o conhecimento dos cuidadores sobre o assunto. A qualidade do processo decisório é insatisfatória devido à baixa frequência das conversas entre cuidadores e equipe de saúde e a má avaliação dos cuidadores sobre a participação da equipe no processo decisório Conclusão: O instrumento de apoio à decisão compartilhada traz benefícios para cuidadores/pacientes submetidos à difícil tarefa de decidir a via de alimentação. Os achados sugerem que a atual qualidade do processo decisório é inadequada.

Resumo Objetivo Avaliar os parâmetros associados a qualidade de vida em pacientes com doenca de Paget ossea (DPO). Metodos Avaliaram‐se pacientes com DPO com os questionarios SF‐36 e WHOQOL‐bref. Excluiram‐se pacientes com outras doencas que pudessem causar comprometimento significativo da qualidade de vida. Buscou‐se por correlacoes entre os resultados e idade, tempo de diagnostico, tipo de envolvimento, dor relacionada com a DPO, limitacao as atividades diarias, deformidades, fosfatase alcalina especifica do osso, extensao do envolvimento e tratamento. Resultados Incluiram‐se 50 pacientes. Os resultados da pontuacao total do SF‐36 e seus dominios, saude fisica e saude mental, se correlacionaram significativamente com a dor ossea e deformidades. O estado civil se correlacionou significativamente com a pontuacao total do SF‐36 e com seu dominio saude mental. Os niveis de BAP e a extensao da doenca se correlacionaram significativamente com o dominio saude fisica do SF‐36. Depois da analise multivariada, os unicos parâmetros que permaneceram significativamente associados a pontuacao total do SF‐36 e aos seus dominios saude mental e saude fisica foram a dor e o estado civil. A pontuacao total do WHOQOL‐bref esteve significativamente associada a dor, ao comprometimento fisico e a deformidades. O escore do Dominio 1 (fisico) do WHOQOL‐bref esteve significativamente associado ao estado civil, dor e deformidades, enquanto o Dominio 2 (psicologico) esteve associado ao estado civil, comprometimento fisico e tipo de envolvimento. Depois da analise multivariada, a presenca de dor, deformidades e estado civil esteve significativamente associada a pontuacao total do WHOQOL‐bref e a pontuacao do seu Dominio 1. Os resultados do WHOQOL‐bref 2 foram significativamente preditos pela dor e pelo estado civil. Conclusao O principal fator associado aos escores do SF‐36 foi a dor ossea, enquanto a dor ossea e as deformidades estiveram associadas ao WHOQOL‐bref.

BACKGROUND: To contribute to the understanding of the coronavirus disease (COVID-19) pandemic, this study evaluated the correlations of the frequencies of COVID-19 cases, hospitalisations due to COVID-19, and deaths due to COVID-19 with social isolation indices and outpatient prescriptions of hydroxychloroquine and chloroquine in the state of Santa Catarina, southern Brazil. METHODS: This was an analytical, observational, retrospective study based on secondary data that were obtained from public Brazilian databases and covered the period from March 1, 2020 to October 31, 2020 (epidemiological weeks 10-44). Data on weekly COVID-19 cases, hospitalisations and deaths due COVID-19, sales of chloroquine and hydroxychloroquine, and social isolation indices were obtained. Associations between the variables were tested using multiple linear regression analysis. RESULTS: In all regions of Santa Catarina, there were almost simultaneous peaks of COVID-19 pandemic in weeks 28-31, followed by a sudden decrease. Social isolation indices were not associated with the outcomes; sales of chloroquine and hydroxychloroquine were significant predictors of all outcomes (p

Corticosteroides (ou corticoides) são fármacos muito utilizados na prática clínica. Uma de suas principais aplicações é no tratamento de doenças de natureza inflamatória ou autoimune, em que são capazes de aliviar a dor, preservar a função de órgãos vitais e até salvar a vida de pacientes graves. No entanto, seu uso também está associado ao risco de efeitos adversos também graves. Por esses motivos, ter destreza em sua prescrição e manejo dos efeitos adversos é uma competência essencial ao clínico. Para facilitar essa tarefa, este artigo resume conceitos de farmacologia, fisiologia e clínica em relação ao uso de corticoides para o tratamento de doenças inflamatórias e autoimunes em pacientes adultos, na forma de dez regras práticas.

Mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) is characterized by its well-defined clinical profile. Limbic encephalitis is increasingly recognized as a possible etiology of adult-onset MTLE-HS, and neuronal autoantibodies have been detected in patients even without previous signs of encephalitis. The aim of this study is to analyze the frequency of specific autoantibodies in patients with MTLE-HS. A case-control study was carried out with 100 patients with MTLE-HS and 50 healthy controls. Sera samples from subjects were tested by indirect immunofluorescence assay for detection of anti-N-methyl-d-aspartate receptor (NMDA-R), anti-contactin-associated protein-like 2 (CASPR2), anti-leucine-rich glioma inactivated 1 (LGI1), anti-gamma aminobutyric acid B receptor (GABA-B-R), anti-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid 1 and 2 receptors (AMPA-1-R and AMPA-2-R), and enzyme-linked immunosorbent assay for detection of anti-glutamic acid decarboxylase 65 (GAD65). Mean age of patients and controls was 41.2 vs 42 years, and 55% vs 56% were female. Mean duration of epilepsy was 27.2 years. No neuronal autoantibodies were found in either group, except for anti-GAD65 in 3 patients and 2 controls. This study adds to the mounting evidence that, in Brazilian patients, MTLE-HS without signs and symptoms of autoimmune encephalitis may be infrequently associated with these autoantibodies. Differences regarding accuracy of used methodologies for autoantibody detection and genetic and environmental characteristics are discussed. Further works with different methodologies tested simultaneously in different populations may help clarify the incongruent study results about autoantibodies in MTLE-HS.

Aim Ankylosing spondylitis (AS) is a chronic inflammatory disease that compromises the axial skeleton, causing pain and disability. The involved mechanisms are not completely understood, but evidence suggests a role of the gut microbiota in eliciting innate immune responses. We conducted an experimental study to determine if AS patients exhibit an enhanced inflammatory response to microbial compounds. Method We incubated whole peripheral blood of AS patients and healthy controls with phosphate-buffered saline (PBS) or lipopolysaccharide (LPS) for 48 h with saturating levels of labeled antibodies (CD66b, CD11b and human leukocyte antigen type DR [HLA-DR]) for flow cytometry. CD11b and HLA-DR expression levels were assessed in polymorphonuclear leukocytes (PMN) (CD66b high - HLA-DR low). We also measured basal CD11b and HLA-DR levels on circulating PMN (without incubation). Results We found that CD11b and HLA-DR levels were similarly elevated in response to LPS on PMNs from healthy controls (HC) and AS patients. Basal levels of CD11b and HLA-DR on circulating PMN from AS patients and HC were similar. However, significantly lower levels of CD11b and HLA-DR were observed in PMNs from AS patients than HC in response to incubation with PBS for 48 h. Conclusion We concluded that the response of AS innate immune cells to LPS is similar to that observed in immune cells from HCs, and suggested that the lower PMN activation of AS patients after 48 h saline incubation is mainly due to anti-inflammatory medication.

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.

Aim: To investigate serum levels of tumor markers in patients with rheumatoid arthritis (RA) and their association with disease activity or the presence of cancer. Method: We performed an observational cohort study including 100 patients with RA and control subjects. Serum levels of tumor markers carcinoembryonic antigen (CEA), cancer antigen (CA) 125, CA 19–9 and CA 15–3 were evaluated along with clinical and laboratorial RA data. Association tests between tumor markers levels and RA disease activity parameters were performed. Patients with abnormal tests were submitted to further investigation, including chest X-ray, colonoscopy, abdominal ultrasonography, upper gastrointestinal endoscopy and mammography, depending on the type of tumor marker that was elevated. Results: Patients with RA had high levels of CEA and CA 19–9 more frequently than controls (P < 0.05). No correlation was found between tumor markers and RA disease activity assessed by the Disease Activity Score 28. Two neoplasms were found, but only one was related to high tumor marker (an ovarian carcinoma with high CA 125 levels).

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% dos pacientes eram do sexo masculino e a idade média de 38,7 ± 17,2 anos. Sessenta e nove dos 392 pacientes (17,6%) apresentaram-se com queixa musculoesquelética. A queixa musculoesquelética mais comum foi lombalgia (33/69). Somente 49,2% 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% versus 62%, P = 0,01) e sinais vitais (46% versus 66%, P = 0,00), porém maior frequência de registro do exame musculoesquelético (49% versus 0,6%, 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% of patients were male and mean age was 38.7 ± 17.2 years-old. Sixty nine out of 392 patients (17.6%) presented with a musculoskeletal complaint. The most common musculoskeletal complaint was low back pain (33/69). Only 49.2% 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% versus 62%, P = 0.01) and vital signs (46% versus 66%, P = 0.002), but a higher frequency of musculoskeletal examination registration (49% versus 0.6%, 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.

Resume Objectifs Etudier le profil lipoproteique de patients atteints du syndrome de Sjogren primaire (SSp) et son association avec des parametres biologiques, y compris les marqueurs de l’inflammation. Methodes Nous avons realise une etude transversale chez des patients atteints de SSp et de temoins sains. Nous avons analyse le profil lipoproteique de 73 patients atteints de SSp et les avons compare a celui de 65 temoins sains. Nous avons evalue les associations eventuelles entre une dyslipidemie chez les patients atteints de SSp et les parametres biologiques, y compris : hypergammaglobulinemie, autoanticorps (anticorps antinucleaires [ANA], facteur rhumatoide [FR], anti-Ro, anti-La) et reactifs de la phase aigue (proteine C-reactive [CRP] et vitesse de sedimentation [VS]). Resultats Les variables demographiques etaient comparables chez les patients et les temoins. Les profils lipoproteiques etaient comparables chez les patients atteints de SSp et les temoins : cholesterol total (204,0 ± 43,39 versus 206,5 ± 42,76 mg/mL, p = 0,73), fraction LDL (131,6 ± 37,38 versus 130,62 ± 38,24 mg/dL, p = 0,88), fraction HDL (49,7 ± 13,5 versus 51 ± 11,5 mg/dL, p = 0,56) et triglycerides (129,3 ± 81,0 versus 116,8 ± 53,5 mg/dL, p = 0,29). Toutefois, les patients atteints de SSp presentaient plus frequemment une dyslipidemie que les sujets sains (76,7 % versus 61,5 %, p = 0,06). La presence de dyslipidemie chez les patients atteints de SSp etait associee a une augmentation de la VS (44,05 ± 28,07 versus 28,28 ± 18,00, p = 0,03), mais pas a d’autres marqueurs biologiques de la maladie et de l’inflammation. Discussion/conclusion Les patients atteints du SSp presentent souvent un profil lipidique anormal, associe a une VS elevee. Ainsi, comme pour d’autres maladies inflammatoires systemiques tels que la polyarthrite rhumatoide (PR) et le lupus erythemateux systemique (LES), le profil lipidique devrait etre evalue chez les patients atteints de SSp, afin d’initier une strategie therapeutique specifique pour la prevention des evenements cardiovasculaires.

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%) mulheres, com idade média ao diagnóstico de 29,6 anos. Hipertensão arterial sistêmica (60,0%) e ausência de pulsos em membros superiores (53,3%) foram os achados clínicos mais comuns ao diagnóstico. As artérias subclávias e carotídeas foram os vasos mais frequentemente acometidos. Doze pacientes (80,0%) 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% dos casos. Três casos (20,0%) 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%) were females, with a mean age of 29.6 years at diagnosis. Systemic hypertension (60.0%) and abolished upper limb pulses (53.3%) were the most common clinical features at the diagnosis. Subclavian and carotid arteries were the most commonly affected vessels. Twelve patients (80.0%) 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% of cases. Three cases (20.0%) 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.

Acquired angioedema is caused by different drugs and lymphoproliferative diseases, and rarely it has also been related to the presence of auto-immune disorders. We report the case of a 47 year old female with systemic lupus erythematosus (SLE) and severe cutaneous involvement who developed recurrent localized angioedema of the face, including lips and eye lids, upper limbs, and thorax, not associated with urticaria, and with reduced levels of C1 esterase inhibitor. Treatment with antimalarials, glucocorticoids, and pulse therapy with methylprednisolone associated with azathioprine did not improve her condition. The patient was also unsuccessfully treated with danazol, and she only showed clinical response after several sessions of plasmapheresis, including resolution of the extensive edema of the gastrointestinal tract.

Spondyloarthritis (SpA) is a musculoskeletal inflammatory disease linked with immune responses to intestinal microbiota, and subclinical intestinal ulcerations that are closely related to inflammatory bowel diseases. Helicobacter pylori is a common cause of gastroduodenal ulceration, and anti-Saccharomyces cerevisiae antibodies (ASCA) are associated with intestinal inflammation in both Crohn disease (CD) and SpA. We investigated the relationship between H. pylori and ASCA. Ninety-one patients with axial SpA and forty with CD were included. ASCA IgG/IgA and anti-H. pylori IgG titers were assessed by ELISA. The proportion of ASCA+ patients in the positive and negative anti-H. pylori IgG groups with SpA and CD were compared using Chi-square tests, and correlations were evaluated using the Spearman’s coefficient. Anti-H. pylori IgG titers were significantly negatively correlated with the ASCA IgG (r = −0.563, p

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.

Behcet's disease (BD) is a systemic inflammatory disorder characterized by recurrent episodes of acute inflammation consisting mainly of neutrophil infiltration around blood vessels in affected tissues. BD probably occurs due to neutrophil-based innate immune responses orchestrated by a complex interplay among gamma-delta T lymphocytes, natural killer T cells, monocytes and Th17 lymphocytes in which type-I interferon is possibly a key element for inflammatory downregulation. However, strong evidence is still scarce. This article compiles the literature in an attempt to summarize the possible mechanisms by which neutrophils are activated in BD and suggests directions for future research.

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% usavam 20-25 mg/semana de MTX e 63,4% usavam 20-25 mg/semana de MTX associado a 20 mg/ dia de LEF. Dos pacientes em terapia combinada, 11,1% tinham níveis anormais das enzimas hepáticas versus 11,5% 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% were using 20-25 mg/week of MTX alone and 63.4% were using 20-25 mg/week of MTX plus 20 mg/day of LEF. Of the patients on the combination therapy, 11.1% had abnormal levels of liver enzymes versus 11.5% 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.

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.

Tumoral necrosis factor alpha blockers are very efficient in the treatment of many inflammatory systemic diseases, including rheumatoid arthritis and psoriasis. However, a paradoxical arouse of psoriasiform lesions may occur in a few patients taking anti-TNFα. The etiology of this rare side effect is still a mystery, and its treatment may be difficult. The authors report the resolution of adalimumab-induced psoriasis in a woman with rheumatoid arthritis after the use of high vitamin D(3) doses for the treatment of vitamin D deficiency. This is the first report of resolution of anti-TNFα-induced psoriasiform lesions by high doses of vitamin D(3) in a patient with rheumatoid arthritis and vitamin D deficiency. This case raises interesting questions on the role of vitamin D deficiency in the pathogenesis of this side effect and on the possible usefulness of high-dose vitamin D(3) in its treatment.

Paget’s disease of bone (PDB) exhibits a marked geographic variation. In Brazil, the prevalence of PDB is unknown and only a few clinical data are available. The aim is to determine clinical, laboratory, imaging and response to treatment data in a large PDB case series in the city of Florianopolis, Brazil. We have performed a retrospective study based on charts reviews of all patients with PDB followed at the University Hospital of the Federal University of Santa Catarina and at five different private rheumatology outpatient offices in Florianopolis, between 1995 and 2009. One hundred and thirty-four patients with PDB were identified. Mean age at diagnosis was 63.2 ± 10.5 years, 67.2% were women, and 91.1% were Caucasian. Positive family history was reported in only 8.2%. Polyostotic disease was found in 75.0% of the cases, bone pain in 77.9%, and bone deformities in 15.9%. Higher levels of AP were significantly associated with polyostotic disease and skull involvement. Pelvic bones were the most frequently affected (53.7%). Complications included deafness in 8.2%, bone fractures in 3.0%, hydrocephalus in 2.2%, and cauda equina syndrome in 0.7% of the cases. Treatment with zoledronic acid achieved the best response with only 2.9% failing to respond adequately. According to literature data, PDB in South America seems to be characterized by an overall low prevalence, but with localized clusters with higher prevalence. The authors have described a cluster of PDB in Florianopolis, in Southern Brazil. Further properly designed studies are necessary to clarify the PDB epidemiology in South America.

Hypertrophic osteoarthropathy (HOA) is characterized by periostitis of tubular bones, thickened skin, and digital clubbing. Its pathogenesis is unknown but an inflammatory factor and increased bone remodeling have been implicated. It is a very rare disease, usually diagnosed late with few therapeutic options. Bone and joint pains are secondary to periostitis and are usually difficult to control. Tumor necrosis factor-alpha is a cytokine that induces other inflammatory cytokine production, has an osteoclastogenic effect in different rheumatic diseases and probably also has an important role in periostitis and the systemic inflammatory manifestations in HOA. We describe the case of a patient with the primary form of HOA, who had refractory bone pain and arthritis that responded partially to infliximab treatment.

Lung involvement in Sjogren's syndrome (SS) can affect trachea, bronchus, small airways, pleura and may cause interstitial lung injury. It may also be associated with malignancies, particularly non-Hodgkin's lymphoma, which is a well-recognized complication of this disease. Here we describe the occurrence of localized amyloidosis presenting as pulmonary nodules in a patient with newly diagnosed SS. We highlight this rare occurrence as a diagnostic possibility that should be considered in the evaluation of pulmonary involvement in this disease.

Zoledronic acid is effective for osteoporosis at a single annual intravenous dose. It usually causes few adverse effects; the most common are related to acute phase reactions. We reported the case of a 64-year-old woman who presented flare-up of hand osteoarthritis after zoledronic acid infusions. Despite the fact that arthralgia is a common side effect of intravenous bisphosphonates, development of inflammatory signs in osteoarthritic joints is a rare event. We hypothesized that this side effect is caused by a release of cytokines secondary to activation of gamma-delta T lymphocytes.

Objectives To investigate the lipoprotein profile of patients with primary Sjogren's syndrome (pSS) and its association with laboratory tests, including markers of inflammation. Methods This is a cross-sectional study among patients with pSS and healthy controls. We analyzed the lipoprotein profile of 73 pSS patients compared to 65 healthy individuals in the control group. We further evaluated possible associations between dyslipidemia in pSS patients and laboratory parameters including: hypergammaglobulinemia, autoantibodies [antinuclear antibodies (ANA), rheumatoid factor (RF), anti-Ro, anti-La], and acute-phase reactants [C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)]. Results Patients and controls were comparable regarding the demographic variables. Lipoprotein profile was similar between pSS patients and controls: total cholesterol (204.0 ± 43.39 versus 206.5 ± 42.76 mg/mL, P = 0.73), LDL fraction (131.6 ± 37.38 versus 130.62 ± 38.24 mg/dL, P = 0.88) and HDL fraction (49.7 ± 13.5 versus 51 ± 11.5 mg/dL, P = 0.56), triglycerides (129.3 ± 81.0 versus 116.8 ± 53.5 mg/dL, P = 0.29). However, patients with pSS had a strong trend to present dyslipidemia when compared to healthy individuals (76.7% versus 61.5%, P = 0.06). The presence of dyslipidemia in pSS was associated with increased ESR (44.05 ± 28.07 versus 28.28 ± 18.00, P = 0.03), but not with other laboratory markers of the disease and inflammation. Discussion/Conclusion pSS patients frequently present abnormal lipid profile, which are associated with higher levels of ESR. Thus, similar to other systemic inflammatory diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), lipid profile should be evaluated in pSS patients, with the aim of initiating specific therapeutic strategy for prevention of cardiovascular events.

A 38-year-old patient presented to the hospital with a 2-month history of fever, malaise, weight loss, and progressive weakness on both sides of his body. Because of weakness in the dorsiflexors of his foot and toe, the patient had a high-stepping gait.

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.
