Previous issue date: 2017-09-27 === Guillain-Barré Syndrome is a polyneuropathy characterized by weakness, often started in an acute way, which bilaterally affects the limbs in a symmetrical manner, although there are some cases with asymmetry. In two-thirds of the patients, the start of the symptoms is preceded by an infectious disease of the upper respiratory or gastrointestinal tract. In literature, there are reports showing that the dengue virus is the causal agent of this syndrome; that way, this research was to identify a presence of the dengue virus as an etiological agent in participants suspected of Guillain-Barré Syndrome in the State of Ceará. The study was performed in a tertiary hospital in the period from April 2016 to March 2017 by means of an active search for participants with clinical suspicion of Guillain-Barré Syndrome. Data collection took place during the hospital stay of the individuals through structured interviews, analysis of medical charts and collection of serum and/or cerebrospinal fluid samples from the participants. In this study, serological diagnoses for dengue (IgG and IgM) and molecular diagnoses were accomplished by using the RT-PCR technique. Of the 23 individuals with clinical suspicion of Guillain-Barré Syndrome, 22 were analyzed according to the inclusion criteria of the research. Of these 22 participants, 11 were diagnosed with Guillain-Barré Syndrome. After performing an IgM and RT-PCR serological test for dengue, four individuals showed positive IgM for dengue, two of them with diagnosis of Guillain-Barré Syndrome and one of them showed positive RT-PCR. The individual who showed positivity for dengue through the RT-PCR method during hospital stay concomitantly with neurological symptoms evolved with severity of the clinical picture, and then died. Therefore, we conclude that, probably, the dengue virus infection seems to be present in a higher proportion than expected, thereby suggesting a possible neglect of this etiology in the investigation of the cases of Guillain-Barré Syndrome in the State of Ceará.
KEYWORDS: Guillain-Barré Syndrome; Dengue fever. === A Síndrome de Guillain-Barré é uma polineuropatia que se caracteriza por fraqueza, geralmente, de início agudo, acometendo bilateralmente os membros de forma simétrica, embora alguns casos apresentem assimetria. Em dois terços dos pacientes, o início dos sintomas é precedido por uma doença infecciosa do trato respiratório superior ou gastrointestinal. Há relatos na literatura do vírus dengue ser o agente causador da síndrome, dessa forma, o objetivo desta pesquisa foi identificar a presença do vírus dengue como agente etiológico em participantes suspeitos da Síndrome de Guillain-Barré no Estado do Ceará. O estudo foi realizado em um hospital terciário, durante os meses de abril de 2016 a março de 2017, através de busca ativa de participantes com suspeita clínica da Síndrome de Guillain-Barré. A coleta de dados ocorreu durante a internação do indivíduo, através de entrevista estruturada, por meio de análise de prontuários e coleta de amostras de soro e/ou líquido cefalorraquidiano dos participantes. Neste estudo, foram realizados diagnóstico sorológicos para dengue (IgG e IgM) e diagnóstico molecular através da técnica de RT-PCR. Dos 23 indivíduos com suspeita clínica da Síndrome de Guillain-Barré, 22 foram analisados conforme os critérios de inclusão da pesquisa. Desses 22 participantes, 11 foram diagnosticados com a Síndrome de Guillain-Barré. Após realizar teste sorológico para dengue IgM e RT-PCR, 4 indivíduos apresentaram IgM positivo para dengue, 2 desses com diagnóstico da Síndrome de Guillain-Barré e um deles apresentou RT-PCR positivo. O indivíduo que apresentou positividade para dengue, através do método RT-PCR, durante o internamento hospitalar concomitante aos sintomas neurológicos, evoluiu com gravidade do quadro e óbito. Portanto, concluímos que, provavelmente a infecção pelo vírus dengue parece estar presente em uma proporção maior que esperada, sugerindo possível negligência desta etiologia na investigação dos casos de Síndrome de Guillain-Barré em nosso Estado.
