Eradication of Helicobacter pylori infection with two triple-therapy regimes of 7, 10 and 14 days ; four years experience

Aim: The efficacy of Croatian two the most frequently used triple-therapy regimes (Pantoprazole 40 mg, Amoxicillin 1g, Metronidazole 500mg or Clarithromycin 500mg b.d.) of 7, 10, and 14-days duration, was investigated in 596 patients with gastric (GU), duodenal ulcer (DU) and non-ulcer-dyspepsia (NUD), treated from january 2002. till december 2005.yrs. Methods: 172 GU (M/F 100/72), 282 DU (M/F 176/106) and 138 NUD (M/F 59/79), HP-positive patients, underwent endoscopy with histology and culture at the beginning and 4-8 weeks after the end of the treatment. They were randomly assigned to six treatments groups: PAMgroups: A-for 14days(n=58), B-for 10days(n=118), C-for 7days(n=122), PACgroups: D-for 14days(n=58), E-for 10days(n=118), F-for 7days(n=122). 560 patients(94%) completed the study. Results: The results of HP-eradications are presented on Table. Conclusion: In all groups (7, 10, 14 days), the triple-therapy containing clarithromycin had greater HP-eradication rate than that containing metronidazole. The eradication rate exceeding 80% in ITT and 90% in PP calculation, was achieved only by 14-and 10-days of PAC and only by 14-days of PAM. No statistically differences were found among all 6-groups in ulcer-healing-rate, and clinical-improvement-rate was slightly higher in patients with ulcers then in patients with non-ulcer-dyspepsia.
