Helicobacter Pylori Eradication Rates of Bismuth-containing Quadruple Therapy vs Modified Quadruple Therapy in Korea

Phase 4
Completed
Conditions
Helicobacter Pylori Infection
Interventions
Drug: PBMT treatment (bismuth-containing quadruple therapy)
Drug: PAMB treatment (modified quadruple therapy)
Registration Number
NCT03665428
Lead Sponsor
Chuncheon Sacred Heart Hospital
Brief Summary

South Korea has the highest incidence of gastric cancer worldwide and Helicobacter pylori infection is still prevalent. Clarithromycin-containing triple therapy is still the primary therapy approved by the Korean government. However, studies of antibiotic resistance has shown that regional resistance pattern to antibiotics such as clarithromycin, metronidazole, or quinolone. Recent study in Korea has shown that modified-quadruple therapy has comparable eradication rate to concomitant therapy. However, there has been no comparable study of modified-quadruple therapy with bismuth-containing quadruple therapy. The aim of this study is to compare the eradication rate of modified-quadruple therapy and bismuth-containing quadruple therapy with presenting phenotypic and genotypic antibiotic resistance profile.

Detailed Description

South Korea has the highest incidence of gastric cancer worldwide and Helicobacter pylori infection is still prevalent. Clarithromycin-containing triple therapy is still the primary therapy approved by the Korean government. However, studies of antibiotic resistance has shown that regional resistance pattern to antibiotics such as clarithromycin, metronidazole, or quinolone. Recent study in Korea has shown that modified-quadruple therapy has comparable eradication rate to concomitant therapy. However, this study did not explore the antibiotic resistance profile of Helicobacter pylori. And, there has been no comparable study of modified-quadruple therapy with bismuth-containing quadruple therapy. The aim of this study is to compare the eradication rate of modified-quadruple therapy and bismuth-containing quadruple therapy with presenting phenotypic and genotypic antibiotic resistance profile.
