Can lansoprazole, amoxicillin, and clarithromycin combination still be used as a first-line therapy for eradication of helicobacter pylori?
Abstract
BACKGROUND/AIMS: To determine H. pylori eradication rate with lansoprazole-amoxicillin-clarithromycin treatment regimen, which is the most frequently used as first-line therapy, in the Kirikkale region.
METHODS: One hundred and five patients (44 male, 61 female) with H. pylori infection were included in the study. Patients were divided into two groups based on the endoscopic findings: non-ulcer dyspepsia (n=84, 31 male, 53 female) and acute gastric or duodenal ulcer (n=21, 13 male, 8 female) groups. The diagnosis of H. pylori infection was confirmed if both the urease test and histological examination, which were performed on endoscopic biopsies, were positive. Lansoprazole 30 mg, amoxicillin 1 g, and clarithromycin 500 mg were given twice daily for 14 days to all patients. Endoscopic biopsies were repeated for the evaluation of eradication three months after the treatment.
RESULTS: Ninety-six patients completed the study. Eradication rates were found to be 45.8% (44 of 96) in all patients, 42.1% (32 of 76 patients) in the non-ulcer dyspepsia group and 60% (12 of 20 patients) in the gastric or duodenal ulcer group for per protocol analysis, and the difference between non-ulcer dyspepsia and gastric or duodenal ulcer groups was not statistically significant (p=0.208).
CONCLUSIONS: Lansoprazole-amoxicillin-clarithromycin treatment regimen, the most frequently preferred regimen in H. pylori eradication, is ineffective in our region. The low eradication rates observed with…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 84 participants or records.
