Aim: Helicobacter Pylori infection was associated with the risk of cardiovascular disease; however, the relation between Helicobacter Pylori infection and the lipid profile has not been fully established.
Methods: We measured anti-Helicobacter Pylori antibody concentration and lipid profiles in 6,289 Japanese subjects aged 21-64 years (5,077 male and 1,212 female).
Results: The prevalence of Helicobacter Pylori-seropositive subjects was 46.8% and 39.6% in men and women, respectively. Adjusted mean values of low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol in men were significantly higher and lower in Helicobacter Pylori-seropositive than-negative subjects, respectively, (LDL-cholesterol: 129.0±0.8 vs. 125.3±0.7 mg/dL, p< 0.001, HDL-cholesterol: 54.6±0.3 vs. 56.6±0.3 mg/dL, p< 0.01), whereas these associations were not significant in female subjects. Moreover, the odds ratio of Helicobacter Pylori infection for high LDL-cholesteremia and low HDL-cholesteremia in male subjects was 1.23 (95% CI (confidence interval): 1.08-1.40, p< 0.05) and 1.29 (95% CI: 1.03-1.59, p< 0.05), respectively. Female subjects did not have such associations.
Conclusions: The present study demonstrates that Helicobacter Pylori infection is significantly associ-ated with high LDL-cholesteremia and low HDL-cholesteremia in Japanese male subjects.
