Objective: The aim of this study was to detect the presence of IgM antibodies against dengue (DEN), chikungunya (CHIK) and Japanese encephalitis (JE) in the serum and CSF of patients with Guillaine-Barre syndrome (GBS). Methods: GBS patients (>12 years of age) were included after informed consent. Data on history, clinical manifestations, treatment details, and outcome were collected. Serum and CSF were tested for IgM antibodies against DEN, CHIK, and JE. Results: From April 2018 to December 2019, 95 patients were included in this study. Anti-arboviral IgM antibodies were detected in 30 patients (31.5%) (CSF 11, serum 13, both CSF and serum 6). Serum IgM antibody was present in 19 patients (JE 8, DEN 5, CHIK 2, more than 1 virus 4). Of the 66 patients who underwent CSF studies, antibodies were present in 17 (CHIK 14, DEN 1, more than 1 virus 2). Antibody positivity did not affect the outcome of GBS. Conclusion:One-third of the GBS patients had evidence of recent infection by arboviruses. This suggests that DEN, CHIK, and JE could be the inciting event for GBS in endemic regions.
