摘要

Meningitis is a common life threatening disease which may be caused by a bacterium, fungus, or virus. Here, the presence of a Helicobacter pylori antigen was investigated in serum and CSF samples from 173 individuals with meningitis. The influence of H. pylori infection on CSF levels of Thl/Th2 cytokines was also evaluated. H. pylori antigen was detected using ELISA and Western blot based on specific anti-H. pylori antibody. Thl/Th2 cytokines (IFN-gamma IL-10, respectively) were also determined. A target epitope of 58-kDa was detected in selected CSF and serum samples using Western blot. H. pylori antigen was detected in the CSF samples of 75 of meningitis patients showing H. pylori antigen in their sera. A significant correlation (p < 0.001, r = 0.21) was shown between serum and CSF levels of 58-kDa H. pylori antigen. Only the levels of Thl cytokine (IFN-gamma) were significantly higher (p < 0.05) in CSF of meningitis patients positive for H. pylori antigen than negative patients with meningitis. In conclusion, the 58-kDa H. pylori antigen crossed the blood brain barrier and entered the CSF of patients with meningitis. A significant upregulation of Thl response may be associated with H. pylori infection in patients with meningitis.
