Efficacy of proton pump inhibitors for patients with duodenal ulcers: A pairwise and network meta-analysis of randomized controlled trials
Abstract
BACKGROUND/AIM: To compare the efficacy and tolerance of different proton pump inhibitors (PPIs) in different doses for patients with duodenal ulcers.
MATERIALS AND METHODS: An electronic database was searched to collect all randomized clinical trials (RCTs), and a pairwise and network meta-analysis were performed.
RESULTS: A total of 24 RCTs involving 6188 patients were included. The network meta-analysis showed that there were no significant differences for the 4-week healing rate of duodenal ulcer treated with different PPI regimens except pantoprazle 40 mg/d versus lansoprazole 15 mg/d [Relative risk (RR) = 3.57; 95% confidence interval (CI) = 1.36-10.31)] and lansoprazole 30 mg/d versus lansoprazole 15 mg/d (RR = 2.45; 95% CI = 1.01-6.14). In comparison with H2receptor antagonists (H2RA), pantoprazole 40 mg/d and lansoprazole 30 mg/d significantly increase the healing rate (RR = 2.96; 95% CI = 1.78-5.14 and RR = 2.04; 95% CI = 1.13-3.53, respectively). There was no significant difference for the rate of adverse events between different regimens, including H2RA for a duration of 4-week of follow up.
CONCLUSION: There was no significant difference for the efficacy and tolerance between the ordinary doses of different PPIs with the exception of lansoprazle 15 mg/d.
