Abstract:
Sera from 80 patients suffering from gastritis and/or digestive ulcer were examined for IgG, IgA and IgM to Helicobacter pylori by enzyme-linked immunosorbent assay (ELISA). Anti-H. pylori IgG and IgA in serum could be used for diagnosis of H. pylori infection, but the former had good sensitivity (92.0%) and the latter had a great specificity (94.4%). Serum anti-H, pylori IgM level was not associated with H. pylori infection. There were no remarkable relationship between H. pylori infection degree arid levels of anti-H, pylori IgG IgA. The positive percentage of anti-H, pylori IgG of health population deceased after 50 years old but the anti-H, pylori IgA increased.
