Abstract

Background: Helicobacter pylori infection has become more and more resistant to conventional first-line treatment regimens. So, there is a considerable interest in evaluating new antibiotic combinations and regimens. Nitazoxanide is an anti-infective drug with demonstrated activity against protozoa and anaerobic bacteria including H. pylori. This work is designed to evaluate the efficacy and safety of a unique triple nitazoxanide-containing regimen as a treatment regimen in Egyptian patients with H. pylori infection.

Methods: Two hundred and 24 patients with upper gastrointestinal tract (GIT) dyspeptic symptoms in whom H. pylori -induced GIT disease was confirmed were included in the study. They have been randomized to receive either nitazoxanide 500 mg b.i.d., clarithromycin 500 mg b.i.d., and omeprazole 40 mg twice daily for 14 days or metronidazole 500 mg b.i.d., clarithromycin 500 mg b.i.d., and omeprazole 40 mg twice daily for 14 days. Laboratory evaluation for H. pylori antigen within the stool was performed 6 weeks after cessation of H. pylori treatment regimens to assess the response.

Results: The response to treatment was significantly higher in group 1 of nitazoxanide treatment regimen than group 2 of traditional treatment regimen. One hundred and six cases (94.6%) of 112 patients who completed the study in group 1 showed complete cure, while only 63 cases (60.6%) of 104 patients who completed the study in group 2 showed the same response according to per-protocol (PP) analysis (P<.001). The regimen was well tolerated by all the patients enrolled in the study.

Conclusion: Nitazoxanide-containing triple therapy is a promising therapy for the first-line eradication of H. pylori. (ClinicalTrials.gov Identifier: NCT02422706).
