RESUMO
ABSTRACT In 2004, a global spread of Chikungunya fever affected most tropical and subtropical regions of the world. In 2016, an outbreak occurred in Northeast Brazil with hundreds of cases documented. Solid organ transplant recipients have a modified immune response to infection and the clinical course is usually different from immunocompetent patients. The diagnosis can be challenging in this population. Most reports describe patients residing in endemic areas, although we must emphasize the importance of differential diagnosis in kidney transplanted travelers who visit endemic regions, such as Northeast Brazil. Here, we reported a case of a kidney transplant recipient that acquired Chikungunya fever after a trip to an endemic region at Northeast Brazil during the outbreak in 2016, with a good clinical evolution. We also present warning recommendations for travelers to endemic areas as additional measures to prevent disease outbreaks.
RESUMO Em 2004, um surto global de Chikungunya afetou a maioria das regiões tropicais e subtropicais do mundo. Em 2016, um surto ocorreu no Nordeste do Brasil com centenas de casos documentados. Receptores de transplantes de órgãos sólidos têm uma resposta imune modificada à infecção, e o curso clínico é geralmente diferente daquele em pacientes imunocompetentes. O diagnóstico pode ser desafiador nessa população. A maioria dos relatos descreve pacientes residentes em áreas endêmicas, embora devamos enfatizar a importância do diagnóstico diferencial em viajantes transplantados renais que visitam regiões endêmicas, como o Nordeste do Brasil. Aqui, nós relatamos o caso de um receptor de transplante renal que adquiriu febre Chikungunya após uma viagem a uma região endêmica no Nordeste do Brasil durante o surto de 2016, com uma boa evolução clínica. Também apresentamos recomendações de alerta para viajantes em áreas endêmicas, como medidas adicionais para prevenir surtos de doenças.
