Abstract

Aim: To evaluate the possible long-term effects of Helicobacter pylori infection on Hemoglobin A1c and fasting blood sugar levels in patients with type 2 diabetes.

Background: Helicobacter pylori causes the gastrointestinal tract inflammation, which it plays an important role in distortion of glucose and lipids absorption that altered lipid metabolism and energy harvesting and develops type 2 diabetes, insulin resistance and has been linked to impaired blood glucose.

Patients and methods: In this clinical trial, patients with type 2 diabetes and confirmed Helicobacter pylori infection were recruited from the endocrinology clinic of the Shahid Beheshti University Tehran, Iran. Before and after 3 months of eradication therapy fasting blood samples were taken and glycalated hemoglobin levels and fasting blood sugar levels were measured.

Results: 85 (27 male 31.8%, 58 female 68.2%) patients with the mean age of 52.±4.7 years were recruited. 52 (62%) had successful Helicobacter pylori eradication (16 male, 30.8% and 36 female, 69.2%). The mean glycalated haemoglobin levels before successful treatment was 8.7±1.1 and after treatment was 8.3±0.9 and difference was significant (p<0.001). Mean IgG level of serology was 3.3±1.1 and the correlation with glycalated haemoglobin was significant (p=0.02) (r=0.4).

Conclusion: Our results indicate that the Helicobacter pylori treatment can improve the mean glycalated haemoglobin in patients with type 2 diabetes. More investigations will be required to evaluate the effects of Helicobacter pylori eradication among different age groups and in relation to obesity status, diabetes and other disease, and it may be beneficial for patients at risk of diabetes to be checked for the presence of Helicobacter pylori infection.
