Treatment of chikungunya chronic arthritis: A systematic review.

INTRODUCTION: Chikungunya (CHIK) is a tropical arbovirus, transmitted by the female mosquito Aedes aegypti and Aedes albopictus. In Brazil, there have been cases reported since 2014. The initial manifestations of this virus are sudden onset high fever, headache, chills, rashes, myalgia and intense joint pain. Usually, CHIK presents the acute and chronic phases, the latter characterized by bilateral polyarthralgia, which can last for months or even years. During this period, autoimmune diseases can be triggered, making the picture even more complicated. METHOD: A systematic review was performed on the PubMed and Scielo databases in January 2017. Clinical trials, cohorts, case-control and case reports were included in the study. Expert opinions, societal consensuses and literary reviews were exclusion criteria. Studies were conducted in English, Spanish and Portuguese. The studies were descriptively analyzed and the data was grouped according to methodological similarity. RESULTS: Twenty-four (24) articles were selected and, in compliance with the inclusion and exclusion criteria, 18 were eliminated, with six studies remaining in the present review: five clinical trials and one case report. CONCLUSION: When the manifestations of CHIK become chronic and, the longer they last, more complications arise. Polyarthralgia can be immaterial, distancing individuals from their daily-life activities. Anti-inflammatory drugs (either steroid or not), in addition to immunosuppressants, homeopathy and physiotherapy are measures of treatment that, according to the literature, have been successful in relieving or extinguishing symptoms. However, it is fundamental that studies of CHIK treatment be further developed.

Resumo Introdução: A chikungunya é uma arbovirose tropical, transmitida pela fêmea dos mosquitos Aedes aegypti e Aedes albopictus. No Brasil, existem casos relatados desde 2014. As manifestações iniciais dessa virose são: febre alta de início súbito, cefaleia, calafrios, erupções cutâneas, mialgia e dor articular intensa. Normalmente, a chikungunya apresenta as fases aguda e crônica, sendo a última caracterizada pela poliartralgia bilateral, que pode durar meses e até anos. Durante esse período, doenças autoimunes podem ser desencadeadas, tornando o quadro ainda mais complicado. Método: Foi realizada uma revisão sistemática nos bancos de dados PubMed e Scielo em janeiro de 2017. Ensaios clínicos, coortes, casos-controle e relatos de caso foram incluídos na pesquisa. Opiniões de especialista, consensos de sociedades e revisões literárias foram critérios de exclusão. Foram avaliados estudos nas línguas inglesa, espanhola e portuguesa. Os estudos foram analisados descritivamente, e os dados agrupados, conforme semelhança metodológica. Resultados: Foram selecionados 24 artigos; em obediência aos critérios de inclusão e exclusão, 18 foram eliminados, restando seis estudos na presente revisão: cinco ensaios clínicos e um relato de caso. Conclusão: Quando as manifestações da chikungunya se tornam crônicas, quanto mais tempo duram, mais complicações surgem. A poliartralgia pode ser incapacitante, afastando os indivíduos das suas atividades de vida diária. Anti-inflamatórios (esteroides ou não), somados a imunossupressores, homeopatia e fisioterapia são medidas de tratamento que, conforme a literatura, têm alcançado êxito no alívio ou na extinção dos sintomas. Todavia, é fundamental que os estudos do tratamento da chikungunya sejam mais aprofundados.
