Comparison of half-dose and full-dose triple therapy regimens for Helicobacter pylori eradication in patients with end-stage renal disease

摘要

>Aim: The aim of this study was to compare the half-dose and full-dose triple therapy regimens for Helicobacter pylori (Hp) eradication in patients with end-stage renal disease. >Background: H. Pylori is one the most important causes of dyspepsia in patients with end-stage renal disease (ESRD). >Patients and methods: Sixty-six patients with ESRD were enrolled in the study with Hp infection and peptic disease with a need of Hp eradication. Patients were randomly assigned to full-dose (A=35 patients) or half-dose group (B=31 patients). Patients received clarithromycin 500 mg, amoxicillin 1000 mg and omeprazole 20 mg twice daily in group A and clarithromycin 250 mg and amoxicillin 500 mg twice daily and omeprazole 20 mg once daily in group B for two weeks. Patients provided stool samples 4 weeks of completing study to assess the success of Hp eradication by Hp-specific stool antigen. Finally, the rate of eradication and complications were compared between two groups. >Results: The successful Hp eradication was achieved in 26 patients (74%) in group A and in 22 patients (74%) in group B. The difference between 2 groups was not statistically significant (p=0.973) (per protocol analysis). >Conclusion: Half-dose triple-therapy with clarithromycin, amoxicillin and omeprazole is as effective as full-dose triple-therapy to eradicate the Hp in patients with ESRD. According to lower toxicity level, complications and cost in half-dose regimen in this subset of patients, this protocol is advised.
