Campylobacter jejuni infection in Guillain-Barré syndrome: a prospective case control study in a tertiary care hospital

Abstract

Background: Guillain-Barré syndrome (GBS), is a common post-infectious polyradiculoneuropathy worldwide. The commonest implicated causative organism the world over is Campylobacter jejuni (C. jejuni). This study was carried out to determine the relationship between C. jejuni infection and GBS in an Indian setting.

Materials and methods: This prospective study was carried out on a cohort of 50 patients with GBS who were treated in a tertiary care hospital in India. Based on electrophysiological findings the patients were divided into various subtypes. Serology for C. jejuni (Immunoglogulin G, IgG and Immunoglogulin, IgM) using an enzyme-linked immunosorbent assay method (ELISA) was done both in patients and 40 age, sex and geographically matched controls.

Results: Evidence of recent C. jejuni infection was present in 30% of GBS patients compared to 8% of controls (15/50 vs. 3/40 P<0.005). Eight (47%) C. jejuni-positive patients reported symptoms of gastroenteritis 4-30 days (mean 13 days) prior to onset of GBS. Of the 15 patients with evidence of C. jejuni infection, 10 (67%) patients had axonal type of GBS. Axonal variety of GBS presented in a younger age group compared to acute inflammatory demyelinating polyradiculoneuropathy (AIDP) patients (mean age: axonal vs. AIDP: 30.11 + 13.73 vs. 40.2 + 18.77). C. jejuni-positive patients presented mainly in spring and winter and had a similar age and sex incidence as compared to the rest of the GBS patients.

Conclusions: Preceding C. jejuni infection is common among GBS patients and is often associated with the axonal variety of GBS. Axonal variety of GBS generally presents in a younger age group as compared to AIDP.
