Guillain-Barre syndrome: demographics, clinical features, and outcome in a single tertiary care hospital, Oman

Abstract

Objective: Guillain-Barre syndrome (GBS) is an acute autoimmune-mediated peripheral nervous system disease. Different studies from various geographical regions have reported considerable variability regarding its epidemiology, clinical features, and outcome. Our study aimed to document demographics, clinical features, and outcomes among GBS patients admitted to a single tertiary care hospital in Muscat, Oman.

Methods: A retrospective data analysis of 44 GBS patients, who were admitted during a two-year period from January 2016 to December 2018 at Khoula hospital, was carried out. Demographics, antecedent illness, duration of symptoms, muscle power graded by the Medical Research Council scale (MRCs), sensory & autonomic involvements, nerve conduction study results, CSF study, need for ventilation, condition at discharge and subsequent follow-up status were obtained.

Results: Ninety-one percent of the patients were Omanis, with male predominant 63.6% and the average age was 42.69 years. Quadriparesis was the predominant presenting complaint (61.3%) and AIDP was the commonest variant (52%). All patients received a single cycle of IVIg and (13.6%) patients admitted to the ICU for mechanical ventilation. The study showed good outcome and recovery in 18 months follow up.

Conclusion: The clinical presentation of GBS in the majority of patients in Oman is similar to those reported in previous studies, and most patients had favorable prognoses. Our results can be used as baseline data for understanding the characteristics of GBS in Oman and, consequently, for better management.
