Study on the association between the efficacy of peg-IFN and the complexity of TP and RT in chronic hepatitis B / 中华实验和临床病毒学杂志

ABSTRACT

Objective@#To explore the association between the efficacy of peg-IFN and the complexity of TP and RT regions of hepatitis B virus (HBV) in chronic hepatitis B.@*Methods@#Patients with HBeAg positive, HBV DNA positive chronic hepatitis B were given peg-interferon 180 μg once a week for subcutaneous injection, and baseline information was collected from baseline and after 12 weeks’ treatment. The baseline HBV DNA TP and RT fragments were amplified, database, high-throughput sequencing, and the average genetic distance calculation.@*Results@#Data of 108 patients were analyzed by logistic regression. RT area fragment Markov distance and TP area fragment Shannon quotient for HBV DNA response were calculated. ALT level is good for HBeAg response. HBsAg level is bad for HBsAg response.@*Conclusions@#The complexity of the baseline TP and RT regions may be associated with the efficacy of peg-interferon therapy for CHB.
