Abstract
We evaluated the putative factors for the onset of Guillain-Barré syndrome (GBS) in Harbin, China by a case-control study based on the information from GBS patients identified from a population-based incidence survey, which is the first study of this kind in China. Sixty-nine GBS patients were identified during a 1-year period from 1 October 1997 to 30 September 1998, and they were matched with 69 controls for gender and age (+/-5 years). GBS diagnosis was validated by senior neurologists and GBS patients were followed up for 6 months after onset. Odds ratio (OR) and 95% confidence intervals (CI) for each putative factor for the onset of GBS were calculated and compared between GBS cases and controls. Precedent respiratory infections within 2 months before onset were found to be significantly more frequent in GBS patients than in controls (OR = 1.68, 95% CI: 1.21-2.33). Although the number of cases with gastroenteritis among GBS patients was more than double of that in the controls, the difference was not statistically significant (OR = 2.25, 95% CI: 0.73-6.96). Other putative factors as well as characteristics regarding family situation, education level, occupation, etc., were not found to be statistically different between GBS patients and controls.This publication has 19 references indexed in Scilit:
