Aim: To evaluate the effect of Helicobacter Pylori (H. pylori) eradication on microalbuminuria in type 2 diabetic patients.
Methods: Consecutive patients with dyspepsia, type 2 diabetes mellitus and microalbuminuria were recruited. Upper gastrointestinal endoscopy and rapid urease test (H. pylori fast) were performed for detecting H. pylori infection. Patients with H. pylori infection were given triple treatment. Urea breath tests were performed for all patients after eradication treatment. According to the eradication status, patients were divided into two groups, as H. pylori negative, group 1 (successful eradication group) and H. pylori positive, group 2 (unsuccessful eradication group). Twenty-four hour urine was also collected from all patients at baseline and after H. pylori eradication treatment.
Results: A total of 69 patients were included in the study. There were no significant differences between groups for anthropometric measurements and laboratory tests at baseline (p > 0.05). An expected significant difference was found for microlabuminuria and fasting glucose between the two groups. Microalbuminuria and fasting glucose levels were signicantly reduced in the H. pylori negative group compared with the H. pylori positive group after eradication treatment (p < 0.05). Although there was no significant decline in HbA1c levels in the H. pylori negative group, there were relatively lower HbA1c levels compared with baseline for both groups. The rate of attaining normoalbuminuria after eradication was significantly higher in group 1 compared to group 2 (p < 0.05).
Conclusion: H. Pylori eradication was found to have a favorable effect on reducing microalbuminuria in diabetic patients.
