Unraveling the neurological intricacies: a rare case of Guillain-Barre syndrome in dengue fever.

Abstract

Dengue, caused by the dengue virus, presents with various clinical manifestations, including rare neurological complications. Guillain-Barre Syndrome (GBS), an immune-mediated polyradiculoneuropathy, is a rare complication, often triggered by antecedent infections. Herein, we report the case of a 30-year-old male presenting with GBS following dengue fever. His clinical course revealed classic GBS symptoms, including ascending weakness and bulbar involvement, with no noted infection that could plausibly explain a trigger for GBS. Diagnosis entailed cerebrospinal fluid analysis and nerve conduction studies which confirmed acute inflammatory demyelinating polyradiculoneuropathy. Treatment involved plasmapheresis, yielding a positive response. This case underscores the association between dengue and GBS, emphasizing the need for heightened clinical suspicion in endemic regions like Nepal.
