Abstract

Triple therapy has long been used as the first-line therapy for Helicobacter pylori (H. pylori) infection, but its efficacy has been continuously decreasing over the past 10 years. The main cause of decrease in the H. pylori eradication rate of conventional triple therapy is increasing resistance of H. pylori to clarithromycin. The H. pylori-associated factors affecting the eradication rate of conventional triple therapy are antibiotic resistance, colonization density of H. pylori in the gastric mucosal membrane, and virulence factors of cagA and vacA. Host factors are medication adherence, excess gastric acid secretion, cytochrome P450 gene polymorphism (CYP2C19), treatment duration, drug side effects, underlying gastroduodenal disease, gastritis pattern, smoking, diabetes, obesity, etc. Due to decrease in the H. pylori eradication rate of the triple therapy, the current standard first-line treatment for H. pylori infection, it has become necessary to develop a new first-line treatment capable of increasing the H. pylori eradication rate.
