Optimized-dose Amoxicillin Versus Standard-dose Amoxicillin for Quadruple Therapy in Helicobacter Pylori Eradication — Helicomatri  

Helicobacter Pylori Clinical Trial

Official title:
Prospective Randomized Trial: Comparison Between Optimized-dose Amoxicillin and Standard-dose Amoxicillin for Quadruple Therapy in the Treatment of Helicobacter Pylori Infection in Tunisian Patients

Clinical Trial Summary

The goal of this prospective randomized clinical trial is to compare the rate of Helicobacter Pylori (HP) eradication after standard or dose-optimized amoxicillin quadritherapy in patients naïve to any anti-HP treatment and with chronic HP infection documented by histological examination. The main questions it aims to answer are: - compare the eradication rate of H.Pylori after a standard concomitant quadritherapy with 2g of amoxicillin versus an optimized quadritherapy with 3g of amoxicillin, in Tunisian population - Identify different factors associated with poor therapeutic response Patients were randomly assigned to either standard quadruple therapy (Qs-14: amoxicillin 1g twice daily, clarithromycin 500mg twice daily, metronidazole 500mg twice daily and esomeprazole 40mg twice daily for 14 days), or optimized quadruple therapy (Qo-14: amoxicillin 1g three times a day, clarithromycin 500mg twice daily, metronidazole 500mg twice daily and esomeprazole 40mg twice daily for 14 days). Eradication control was performed by urea breath test.

Clinical Trial Description

This study was a prospective, randomized, single-center study conducted in the hepato-gastroenterology department of Mahmoud Matri Hospital in Ariana, in collaboration with the bacteriology and biochemistry laboratory of the same hospital, the anatomopathology department of Abderrahmen Mami Hospital in Ariana, and the private clinical analysis laboratory "Fendri". all patients aged from 18 and 65 years-old with H. pylori infection documented by pathological examination of per endoscopic gastric biopsies were recruited. This was a population of patients who had undergone upper endoscopy (UE) and in whom the search for H.Pylori was indicated, according to the European Maastrich IV recommendations. Eligible subjects were randomly assigned in a 1:1 ratio to receive either standard quadruple therapy (Qs-14) including : amoxicillin 1g twice daily ,clarithromycin 500mg twice daily ,metronidazole 500mg twice daily and esomeprazole (Medis Pharmaceutical Company) 40 mg twice daily for 14 days, or optimized quadruple therapy (Qo-14) including : amoxicillin 1g three times daily ,clarithromycin 500mg twice daily, metronidazole 500mg twice daily and esomeprazole 40 mg twice daily (Medis Pharmaceutical Company) for 14 days. Eradication control was performed by 13C-UBT at least 4 weeks after the end of the treatment. ;
