We evaluated sweat, blood and urine specimens obtained from an ongoing cohort study in Brazil. Samples were collected at pre-established intervals after the initial rash presentation and tested for Zika virus (ZIKV) RNA presence by real-time reverse transcriptase polymerase chain reaction (rRT-PCR). From 254 participants with confirmed infection, ZIKV RNA was detected in the sweat of 46 individuals (18.1%). Sweat presented a median cycle threshold (Ct) of 34.74 [interquartile range (IQR) 33.44-36.04], comparable to plasma (Ct 35.96 - IQR 33.29-36.69) and higher than urine (Ct 30.78 - IQR 28.72-33.22). Concomitant detection with other specimens was observed in 33 (72%) of 46 participants who had a positive result in sweat. These findings represent an unusual and not yet investigated virus shedding through eccrine glands.

CONTEXTO E OBJETIVO: O desenvolvimento científico e tecnológico é crucial para avançar o Sistema Único de Saúde e promover qualidade de vida. Analisou-se como o Ministério da Saúde (MS) apoiou a pesquisa clínica para proporcionar autonomia, auto-suficiência, competitividade e inovação no complexo industrial produtivo da saúde, segundo a Política Nacional de Ciência, Tecnologia e Inovação em Saúde. TIPO DE ESTUDO E LOCAL: Estudo descritivo baseado em dados secundários, realizado no Departamento de Ciência e Tecnologia, Ministério da Saúde. MÉTODOS: O banco de dados gerencial de pesquisas do MS, PesquisaSaúde, foi analisado de 2002 a 2009, empregando a palavra chave "pesquisa clínica" nos campos "sub-agenda principal" ou "sub-agenda secundária". Foram encontrados 368 projetos, classificados em seis categorias: pesquisa biomédica básica, estudos pré-clínicos, pesquisa clínica expandida, ensaios clínicos, infraestrutura e avaliação de tecnologias em saúde. A partir da revisão estruturada sobre "financiamento da pesquisa clínica", resultados de países selecionados são apresentados e discutidos. RESULTADOS: O total investido foi R$ 140 milhões. A maioria dos projetos apoiou "pesquisa biomédica básica" e os maiores investimentos foram em "ensaios clínicos" e projetos de "infra-estrutura". O Sudeste deteve a maior proporção de projetos e recursos financeiros. Em alguns aspectos, o Brasil está à frente de outros países do BRICS (Rússia, Índia, China e África do Sul), sobretudo no estabelecimento da Rede Nacional de Pesquisa Clínica. CONCLUSÃO: O MS assegurou investimentos para incentivar a pesquisa clínica no Brasil, contribuindo para promover a coesão entre os investigadores, as políticas de saúde e o complexo industrial da saúde.

CONTEXT AND OBJECTIVE: Scientific and technological development is crucial for advancing the Brazilian health system and for promoting quality of life. The way in which the Brazilian Ministry of Health has supported clinical research to provide autonomy, self-sufficiency, competitiveness and innovation for the healthcare industrial production complex, in accordance with the National Policy on Science, Technology and Innovation in Healthcare, was analyzed. DESIGN AND SETTING: Descriptive investigation, based on secondary data, conducted at the Department of Science and Technology, Ministry of Health. METHODS: The Ministry of Health's research management database, PesquisaSaúde, was analyzed from 2002 to 2009, using the key word "clinical research" in the fields "primary sub-agenda" or "secondary sub-agenda". The 368 projects retrieved were sorted into six categories: basic biomedical research, preclinical studies, expanded clinical research, clinical trials, infrastructure support and health technology assessment. From a structured review on "clinical research funding", results from selected countries are presented and discussed. RESULTS: The amount invested was R$ 140 million. The largest number of projects supported "basic biomedical research", while the highest amounts invested were in "clinical trials" and "infrastructure support". The southeastern region had the greatest proportion of projects and financial resources. In some respects, Brazil is ahead of other BRICS countries (Russia, India, China and South Africa), especially with regard to establishing a National Clinical Research Network. CONCLUSION: The Ministry of Health ensured investments to encourage clinical research in Brazil and contributed towards promoting cohesion between investigators, health policies and the healthcare industrial production complex.

INTRODUÇÃO: o HTLV-1 é um retrovírus humano associado à leucemia de células T do adulto e à mielopatia associada ao HTLV-1 ou paraparesia espástica tropical, que tem sido implicado também no desenvolvimento de auto-imunidade. OBJETIVO: o objetivo deste estudo foi determinar a freqüência de doenças reumáticas auto-imunes em pacientes infectados pelo HTLV-1. PACIENTES E MÉTODOS: foram incluídos nesse estudo 137 indivíduos infectados pelo HTLV-1 atendidos no Ambulatório Multidisciplinar do Serviço de Imunologia do Hospital Universitário Professor Edgard Santos (HUPES) da Universidade Federal da Bahia (UFBA), no período de janeiro de 2003 a maio de 2004. Os pacientes responderam a um questionário geral relacionado a manifestações reumatológicas e questionários específicos para confirmação dos critérios diagnósticos de artrite reumatóide (AR), lúpus eritematoso sistêmico (LES), síndrome de Sjögren e polimiosite. Adicionalmente, todos eles foram submetidos a exames clínicos específicos e avaliação complementar. RESUTADOS: 24 pacientes tiveram o diagnóstico de síndrome de Sjögren (SS) provável (17,5%), 18 pacientes (13,1%) de AR, uma paciente teve diagnóstico de LES e uma de doença mista do tecido conjuntivo (0,7%, respectivamente). Suspeita de artropatia relacionada ao vírus foi encontrada em 22 pacientes (16,1%). Síndrome de Sjögren e AR foram mais freqüentes nos pacientes com mielopatia (33,3 e 25,9%, respectivamente) do que nos portadores assintomáticos (13,6 e 10%, respectivamente). Artropatia relacionada ao HTLV-1 ocorreu com freqüência semelhante em ambos os grupos. CONCLUSÃO: foi observado neste trabalho alta prevalência de síndrome de Sjögren e de AR entre os indivíduos infectados pelo HTLV-1, principalmente naqueles com mielopatia. Diante desses resultados, que reforçam os dados da literatura, deve-se estar atento para a ocorrência de doenças reumáticas auto-imunes nesses pacientes.

INTRODUCTION: the HTLV-1 is a human retrovirus associated with adult T-cell leukaemia (ATL) and with HTLV-1- associated myelopathy or tropical spastic paraparesis, which has also been implicated in the development of autoimmunity. OBJECTIVE: the aim of this study was to determine the frequency of autoimmune rheumatic diseases in patients infected with HTLV-1. PATIENTS AND METHODS: it was included 137 individuals infected with HTLV-1 from the Multidisciplinary Ambulatory of Immunology Service, HUPES-UFBA, Salvador (BA), from January 2003 to May 2004. All participants answered to a general questionnaire regarding rheumathological manifestations and specific questionnaires to confirm the diagnose criteria of rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjögren’s syndrome (SS) and polymyositis. Additionally, they were submitted to specific clinical exams, besides complementary evaluations. RESULTS: 24 patients had diagnose of probable Sjögren’s syndrome (17.5%), 18 patients (13.1%) had RA, one patient had diagnose of SLE (0.7%) and another of mixed connective tissue disease (0.7%, respectively). HTLV-1-associated arthropathy (HAAP) was suspected in 22 individuals (16.1%). Sjögren’s syndrome and RA were more frequent in patients with myelopathy (33.3 and 25.9%, respectively) than in asymptomatic carriers (13.6 and 10%, respectively). The frequency of HTLV-1-associated arthropathy was the same in both groups. CONCLUSION: in this study it was observed a high frequency of Sjögren’s syndrome and RA in individuals infected with HTLV-1, mainly in those with myelopathy. Therefore, with this results that support data in the literature, we should call attention to the occurrence of autoimmune rheumatic diseases in these kind of patients.
