Comparing the Efficacy of 14-day Reverse Hybrid Therapy and 14-day Triple Therapy Plus Bismuth Therapy

Helicobacter Pylori Infection Clinical Trial

Official title:
Compare 14-day Reverse Hybrid Therapy and 14-day Triple Therapy Plus Bismuth on Helicobacter Pylori Eradication

Clinical Trial Summary

Reverse hybrid therapy achieves a higher eradication rate than bismuth (triple therapy plus bismuth) remains unanswered

Clinical Trial Description

With the rising prevalence of antimicrobial resistance, the failure rate of the 7-day standard triple therapy has declined to unacceptable level (<80%) worldwide. Several regimens were suggested to replace standard triple therapy in the area with high clarithromycin resistance, including sequential therapy, concomitant therapy, hybrid therapy and bismuth containing quadruple therapy. A 14-day hybrid therapy invented by our study group appears very promising in H. pylori eradication, achieving eradication rates of 95%. A clinical trial by Hsu et al from our hospital showed 12-day reverse hybrid therapy also achieved high eradication rate, and improved the compliance of patients. Even prolong the treatment duration of standard triple therapy from 7 days to 12 days, the efficacy of eradication was still < 90% (85-88%). The limitation of triple therapy in against resistant-stains was still existed. The addition of bismuth (triple therapy plus bismuth) can improve cure rates despite a high prevalence of antimicrobial resistance. The major bismuth effect is to add an additional 30%-40% to the success with resistant infections. However the direct compare the efficacy between 14-day reverse hybrid therapy and 14-day triple therapy plus bismuth is still insufficiency in Taiwan and worldwide. Choosing a navel therapy or a modifying triple therapy can get better efficacy, it is remained to be determined. Besides genotyping polymorphism of CYP2C19 influenced the metabolism of proton pump inhibit, and could cause decreasing of eradication rate of standard triple therapy. But the influence in 14-day reverse hybrid therapy and 14-day triple therapy plus bismuth is unclear. ;
