Abstract
OBJECTIVE: To investigate the association of Helicobacter pylori infection and serum homocysteine(Hcy) levels with acute cerebral infarction. METHODS: Serum Hp-IgG, Hp-CagA-IgG and Hcy were detected by biological micro-array analysis system in 85 patients with acute cerebral infarction and 40 healthy subjects (control group). RESULTS: The positive rates of Hp-IgG and Hp-CagA-IgG significantly increased in cerebral infarction group compared with controls (P<0.05). There were significant differences in serum Hcy level between Hp-CagA-IgG positive and negative patients (P<0.05), but not between Hp-IgG positive and negative patients (P>0.05). CONCLUSION: CagA-positive Hp infection may increase the risk of cerebral infarction, which might be associated with the increased serum homocysteine level.
