Impact of Creatinine Clearance on Helicobacter Pylori Eradication Rate in Patients With Peptic Ulcer Disease

Gastrointestinal complaints are common in patients with kidney failure. The aim of this study was to investigate the effect of creatinine clearance on Helicobacter pylori (HP) eradication rate in patients with peptic ulcer disease. In this clinical trial, 132 patients with a range of kidney function (normal to end-stage renal disease) and peptic ulcer disease with HP infection were enrolled and divided into 5 groups by their creatinine clearance. For all patients, a 14-day standard regimen of triple therapy for peptic ulcer was started with omeprazole, 20 mg; clarithromycin, 500 mg; and amoxicillin, 1 g; twice per day. After 6 weeks, HP eradication rate were evaluated and compared between the groups with urea breath test. The mean age of the participants was 44.84 ± 12.20 years and 68 (51.5%) were women. The five groups were not significantly different in terms of age, sex distribution, or body mass index. The results of urea breath test at 6 weeks were positive in 23 patients (17.4%). There was no significant difference in HP eradication rate (negative urea breath test) between the five groups. This study showed no association between the success rate of eradication of HP infection and kidney function.
