Helicobacter Pylori Infection Clinical Trial
Official title:
Development of Prediction Model of Treatment Outcome of Helicobacter Pylori Eradication Through "One Sequencing Find All" Approach: With Whole Exome Sequencing for Host and Target Sequencing for Bacteria at Once
The aim of this study is to Identify antibiotic resistance gene mutations in Helicobacter pylori (HP) and genetic diversity of drug metabolism for antibiotics and proton pump inhibitors (PPIs) in patients with HP infection using next-generation sequencing (NGS). The mutation of host/HP strain will be investigated by single NGS, and the eradication results according to genetic polymorphism of host/HP strain will be analyzed.
This study is a prospective observational study for the Helicobacter pylori (HP) infected
patients on typical gastroduodenoscopy (EGD) at Boramae Hospital, Seoul, Korea.
The presence of antibiotic resistance genes of HP and the diversity of the pharmacokinetic
genotypes of the subjects will be investigated by performing single next-generation
sequencing (NGS) analysis using gastric mucosal tissue samples of the HP infected subjects.
The purpose of this study is to collect data on the antimicrobial resistance mutation of HP
(23S rRNA gene, pbp1 gene, rdxA, frxA, frxB gene, 16S rRNA, gyrA, gyrB gene, and Cag A gene)
and to investigate the genetic diversity on the metabolism of antibiotics and proton pump
inhibitors (CYP enzyme) in a Korean population.
The investigators are going to compare the results of standard eradication therapy according
to the resistance mutation of HP and drug genetic diversity of subjects.
