Three-day antibiotic therapy with azithromycin and tinidazole plus lansoprazole or pantoprazole to cure Helicobacter pylori infection: a pilot study
Abstract
OBJECTIVE: The aim of the present study was to investigate and compare the effects of two proton-pump inhibitors, lansoprazole (Limpidex 30 mg, Sigmatau) vs pantoprazole (Peptazol 40 mg, Boehringer Mannheim), included in a three-day antibiotic therapy regimen with azithromycin (Zitromax 500 mg, Pfizer) and tinidazole (Fasigin 500 mg, Pfizer).
DESIGN: Seventy consecutive, H. pylori-positive patients were randomly pre-treated with lansoprazole 30 mg o.d. (once daily) or pantoprazole 40 mg o.d. for two days, and subsequently respectively assigned to one of the two following treatment regimens, given for only three days: regimen A (LAT) comprising lansoprazole 30 mg o.d. plus azithromycin 500 mg o.d. and tinidazole 500 mg b.i.d. (bis in die), or regimen B (PAT) comprising pantoprazole 40 mg o.d. plus azithromycin 500 mg o.d. and tinidazole 500 mg b.i.d. H. pylori status was evaluated by means of histology and rapid urease test at entry, and by 13C-urea breath test alone 8 weeks after treatment.
MAIN OUTCOME MEASURES: Sixty-nine of the enrolled patients completed the study: 34 in the LAT group and 35 in the PAT group. One patient in the LAT group was lost to follow-up. In the LAT group, after the end of treatment, 28/34 patients were H. pylori-negative (per protocol: 82%; intention-to-treat: 80%). In the PAT group, after treatment, 29/35 patients were H. pylori-negative (per protocol and intention-to-treat: 83%). Mild or slight side-effects occurred in only one patient in the LAT…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 35 participants or records.
