AbstractEvidence of recent or ongoing Campylobacter jejuni infection has been found in approximately one out of every four cases of Guillain-Barré syndrome (GBS). It is increasingly accepted that C. jejuni infection is an important causal factor for GBS. However, the likelihood of GBS' occurring following an episode of C. jejuni gastroenteritis has not been measured. The authors measured the incidence of GBS in a large cohort of persons with laboratory-confirmed C. jejuni infection. Cases of C. jejuni infection were derived from the Swedish national laboratory reporting system for the years 1987--1995. Follow-up for GBS was carried out using the Swedish national hospital inpatient register. Nine cases of GBS were detected in the cohort, which comprised 29,563 cases of C. jejuni infection--a rate of 30.4 per 100,000 (95% confidence interval: 13.9, 57.8). This compares with an expected incidence of 0.3 per 100,000 in a 2-month period in the general population. GBS is an important but rare complication of C. jejuni infection. The risk of developing GBS during the 2 months following a symptomatic episode of C. jejuni infection is approximately 100 times higher than the risk in the general population.
