As there are increasing reports of fluoroquinolone resistance on use as a first- or second-line treatment for  Helicobacter pylori  ( H pylori ), we aimed at evaluation of the efficacy and safety of nitazoxanide-based regimen as a rescue regimen in Egyptian patients whose previous traditional treatment for  H pylori  infection failed.In total, 100 patients from the outpatient clinic of the Tropical medicine department, Tanta University hospital in whom the standard triple therapy (clarithromycin-based triple therapy) failed were enrolled in the study. Nitazoxanide (500 mg bid), levofloxacin (500 mg once daily), omeprazole (40 mg bid), and doxycyclin (100 mg twice daily) were prescribed for 14 days. Eradication was confirmed by stool antigen for  H pylori  6 weeks after the end of treatment. Among the patients enrolled in the study, 44% of patients were men and the mean age for the participants in the study was 46.41 ± 8.05, 13% of patients were smokers, and 4% of patients had a previous history of upper gastro-intestinal bleeding. A total of 94 patients (94%) completed the study with excellent compliance. Only 1 patient (1%) discontinued treatment due to intolerable side effects and 5 patients (5%) did not achieve good compliance or were lost during follow up. However, 83 patients had successful eradication of  H pylori  with total eradication rates 83% (95 % CI 75.7–90.3%) and 88.30% (95 % CI 81.8–94.8%) according to an intention-to-treat and per-protocol analysis, respectively. Adverse events were reported in 21% of patients: abdominal pain (6%), nausea (9%) and constipation (12%), (2%) headache, and (1%) dizziness. A 2-week nitazoxanide-based regimen is an effective and safe rescue therapy in Egyptian patients whose previous standard triple therapy has failed.
