Research progress of precise therapy for Helicobacter pylori infection / 中华临床感染病杂志

ABSTRACT

Helicobacter pylori (HP) infection is one of the most prevalent chronic bacterial infections in the world, which is closely related to the development of gastrointestinal diseases, such as chronic gastritis, gastroduodenal ulcer and gastric cancer. Empirical treatment of HP infection may lead to antibiotic resistance, adverse reactions and poor compliance. The decreased HP eradication rate is related to antibiotic resistance, HP converting to coccoid form and admission of proton pump inhibitors (PPI). The implementation of precise therapy can effectively enhance the HP eradication rate, through antibiotics selecting based on detection of drug sensitivity phenotype and drug resistance genes, reducing adverse drug reactions, increasing patient compliance, and rationally administrating PPI, etc. This article reviews the research progress of precision therapy for HP infection to provide reference for clinicians.
