Objective: The efficacy of short-course triple eradication therapy has been documented in patients with Helicobacter pylori infection and normal renal function. We have evaluated a one-week proton-pump inhibitor-based triple therapy for Helicobacter pylori eradication in a retrospective review of patients with chronic renal failure.
Methods: We studied 25 patients (mean age 65.1 +/- 2.4 years) with creatinine clearance <30 ml/min/1.73 m2 or serum creatinine level >200 micromol/L (13 on dialysis), who had Helicobacter pylori infection, documented by histological examination or rapid urease test, together with either peptic ulcer disease or severe gastritis. The combination of Omeprazole 20 mg BID or Lansoprazole 30 mg BID, amoxicillin 1 gm BID and clarithromycin 500 mg BID was given for one week, in addition to therapy for peptic ulcers. All patients were re-endoscoped four weeks later.
Results: All but one patient (96%) had successful eradication. On repeat endoscopy, all 13 patients with peptic ulcers had healed ulcers. For the 12 gastritis patients, three became normal and nine had persistent gastritis. For patients not on dialysis, the serum creatinine level and creatinine clearance remained stable at two weeks after treatment (303 +/- 37 vs. 330 +/- 36 micromol/l, p=ns; 23.6 +/- 3.4 vs. 26.0 +/- 3.9 ml/min/1.73 m2, p=ns, respectively).
Conclusion: The short course triple therapy was highly efficacious for Helicobacter pylori eradication in patients with chronic renal failure, with no adverse effect on renal function.
