Recurrent Guillain-Barré Syndrome: Clinical Profile and Outcome.

Objectives: To compare clinical, neurological, treatment and outcome of recurrent Guillian-Barré Syndrome (GBS) with non-recurrent GBS. Also, to compare different episodes of recurrent GBS. Methods: The patient's case records were retrieved retrospectively from the electronic database and case record files. Clinical profile, nerve conduction study, treatment, and outcome details of children with a diagnosis of GBS admitted in Pediatric Intensive Care Unit (PICU) from 2010 to March 2022 were screened. Recurrent GBS cases, as defined by the National Institute of Neurological and Communicative Diseases and Strokes (NINCDS) criteria, were analysed separately. The comparison was made between the first episode of recurrent GBS with non-recurrent GBS, and predictors of recurrence were identified. A comparison of course and outcome was also done between different episodes of GBS in recurrent cases. Results: Recurrent GBS was observed in 11 (4.7%) out of 234 cases during the study period. The presence of respiratory (p 0.015) and gastrointestinal illness (p 0.007) as preceding illnesses were associated with recurrence. No difference was noted between the first episode of recurrent GBS and non-recurrent GBS. The first and second episodes of GBS in 11 recurrent cases were similar in course and outcome. Conclusions: Recurrent GBS is underreported but a known entity. No difference was seen between the two episodes of recurrent GBS. However, more data is required to find the features of recurrent GBS so that limited PICU resources can be used judiciously and intervention planned accordingly. [ABSTRACT FROM AUTHOR]
