Insights
Eradicating Helicobacter pylori (HP) infection did not significantly alter coronary risk factors like blood sugar, lipids, or fibrinolytic profiles in patients. Further research is needed to clarify the link between HP infection and coronary artery disease.
Area of Science:
- Cardiology
- Gastroenterology
- Epidemiology
Background:
- Epidemiological studies suggest a link between Helicobacter pylori (HP) infection and coronary artery disease.
- Previous research indicates potential associations between HP infection and coronary risk factors.
- Limited and conflicting clinical data exist on risk factor changes post-HP eradication.
Purpose of the Study:
- To prospectively evaluate changes in sugar, lipid, and fibrinolytic profiles after successful HP eradication.
- To investigate the impact of HP eradication on established coronary risk factors.
Main Methods:
- Prospective study involving 48 patients with confirmed gastric HP infection.
- HP eradication using a standard omeprazole-amoxicillin-clarithromycin (OAC) regimen.
- Measurement and comparison of pre- and post-eradication blood sugar, lipid profiles, and fibrinolytic markers.
Main Results:
- Successful eradication of HP infection was confirmed in all participants.
- No statistically significant changes were observed in fasting blood sugar levels post-treatment.
- Lipid profiles (total cholesterol, HDL, LDL, triglycerides) and fibrinolytic profiles (t-PA, PAI-1, fibrinogen, D-dimer) remained unchanged after HP eradication.
Conclusions:
- Successful eradication of Helicobacter pylori does not appear to modify key coronary risk factors.
- The relationship between HP infection and coronary artery disease requires further investigation.
- Current findings suggest that HP eradication alone may not be sufficient to alter cardiovascular risk profiles.
Abstract:
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.
