摘要幽门螺杆菌(HP)感染是目前全球最常见的慢性细菌感染之一，慢性胃炎、胃十二指肠溃疡等胃肠道疾病包括胃癌的发生发展都与HP感染密切相关。HP感染经验治疗导致抗菌药物耐药、不良反应大及依从性差。HP耐药、球形变以及质子泵抑制剂(PPI)等因素导致HP的根除率逐渐下降。基于表型药敏与耐药基因的检测合理选择抗菌药物，改善药物不良反应，提高患者依从性以及合理选择PPI等，实施精准治疗，可有效提高HP的根除率。本文就HP精准治疗相关的研究进展作一综述，为临床HP的根除治疗提供参考。

abstractsHelicobacter 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.
