Re-treatment with peginterferon-ribavirin and direct antiviral agents of patients with chronic hepatitis C after failure of intensified treatment / 中华实验和临床病毒学杂志

ABSTRACT

Objective@#To explore the persistent viral response rate (SVR) in patients with refractory chronic hepatitis C after interferon (IFN) (peginterferon 360 μg qw) and ribavirin (PR) therapy failure. The SVR of patients with refractory chronic hepatitis C was improved by PR combined with direct antiviral agents (DAA) and proper extension of the course of therapy was applied.@*Methods@#Seventeen cases of refractory chronic hepatitis C after IFN(peginterferon 360 μg qw) and ribavirin therapy failure were given PR combined with DAA treatment. The side effects were observed and corresponding adjustments were made on drug dosage, and SVR was recorded.@*Results@#The 17 cases completed the whole course of treatment with PR combined with DAA for 24 weeks. All the 17 patients obtained rapid viralogical response (RVR) and SVR. After treatment, the SVR rate was 100% in patients including those with virologic relapse, retreated or previously non-responsive patients with refractory chronic hepatitis C. The adverse reaction of PR combined with DAA 24 weeks was generally mild.@*Conclusions@#The use of PR combined with DAA re-treatment in patients with refractory chronic hepatitis C can achieve SVR and shorten the treatment time. PR combined with DAA re-therapy is one of effective treatments to improve the rate of sustained viral response in patients with refractory chronic hepatitis C.
