Exploring the Genome-wide Association Study of the Population With Clinical Cure Advantage in the Treatment of Chronic Hepatitis B With Long-acting Interferon

Summary

This study is a real-world case-control study conducted, with 120 CHB patients who received continuous treatment with PEG-IFN-α for more than 24 weeks as study subjects. Among them, the clinical cure group obtained through PEG-IFN-α treatment is the case group; The group that did not achieve clinical cure after PEG-IFN-α treatment was used as the control group, and the case group and control group were allocated cases in a 2:1 ratio. Collect blood samples from subjects as sequencing samples for candidate genes, use high-throughput sequencing technology to detect the whole genome of subjects, identify relevant genetic polymorphism that have predictive value for clinical cure of chronic hepatitis B treated with PEG-IFN-α, and establish a predictive model and calculation formula between gene polymorphism and the efficacy of PEG-IFN-α antiviral therapy.
