Changes of coronary risk factors after eradication of Helicobacter pylori infection.
Several epidemiological studies have shown a positive correlation between chronic gastric infection with Helicobacter pylori (HP) and coronary artery disease. A number of reports also claimed that there are strong relationships between HP infection and coronary risk factors. However, clinical studies concerning the changes of coronary risk factors after eradication of HP infection are few and contradictory. We conducted a prospective study aiming to compare sugar, lipid and fibrinolytic profiles before HP eradication with those after HP eradication. HP infection was confirmed by endoscope-based examinations and eradicated by a standard OAC (omeperazole-amoxicillin-clarithromycin) regimen. We measured and compared pre- and post-eradication blood sugar, lipid profiles (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride) and fibrinolytic profiles (tissue-plasminogen activator, plasminogen activator inhibitor-1, fibrinogen, and D-dimer levels). Forty-eight patients (male:female, 25:23; mean age, 50.8 +/- 11.3 years) with gastric HP infection were enrolled in this study. Although HP infection was confirmed to have been successfully eradicated, no significant changes of blood fasting sugar, lipids or fibrinolytic profiles were found in patients after treatment. Coronary risk factors including fasting sugar, lipid and fibrinolytic profiles were not changed after successful HP eradication treatment. The relationship between HP infection and coronary artery disease needs to be clarified.
