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

• Status: Completed
• Trial end date: 2019-12-31
• Target enrollment: 0
• Participant gender: All

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.
