Abstract

Aim. Triple therapy consisting of a proton pump inhibitor (PPI) and two antibiotics is used as first choice in treating Helicobacterpylori (H- pylori) infection. Since in the North Italian population, metronidazole resistance is less than 40%, this antibiotic would be preferable as first approach. The aim of this randomized study was to assess the efficacy of a metronidazole - based versus a tinidazole-based treatment, in naive patients with H pylori infection. Methods. Diagnosis and eradication of H pylori infection were assessed by 13C-urea breath test, and by histology when an endoscopic examination was necessary. A total of 171 patients was treated: 91 (47 males, mean age 50±3 years)with metronidazole 250 mg q.i.d., amoxicilline 1 gr b.i.d. and PPI standard dose (MAO), and 80 (36 males, mean age 52±3.8 years) with tinidazole 500 mg b.i.d., amoxicilline 1 gr b.i.d. and PPI standard dose (TAO) regimen for 7,10 or 14 days. Results. Three patients suspended MAO treatment due to side effects. H. pylori eradication was obtained as follow indicated. After 7 days, in 23/30 (76.6%) patients in MAO versus 20/27 (74.0%) in TAO regimen. After 10 days, in 20/26 (76.9%) patients in MAO versus 20/26 (76.9%) in TAO regimen. After 14 days, in 25/32 subjects (78.1%) in MAO versus 21/27 (77.7%) in TAO treatment. The differences among durations or between metronidazole-versus tinldazole-based triple therapy were not statistically different. Conclusion. Treatment with metronidazole is as effective as that with tinidazole in terms of efficacy. Moreover, duration did not influence efficacy of treatment.
