Sofosbuvir-based regimens combined with ribavirin for recipients with genotype 1 hepatitis C after liver transplantation: a Meta-analysis / 器官移植

ABSTRACT

Objective To evaluate whether sofosbuvir (SOF)-based direct-acting antiviral agents (DAAs) combined with ribavirin (RBV) (combined RBV) can yield benefits to the recipients infected with hepatitis C virus (HCV) genotype 1 (GT1) after liver transplantation through systematic evaluation and Meta-analysis. Methods Multiple databases at home and abroad were systematically searched, the literature screening was conducted according to relevant standards, the quality of literatures was evaluated and data extraction was performed. The literature was divided into two groups according to the recipients with HCV-GT1 hepatitis after liver transplantation who received the treatment combined RBV or SOF-based DAAs alone without RBV (not combined RBV). Meta-analysis of the data was carried out using Rev Man 5.3 and R3.4.3 software. The incidence of sustained virological response 12 weeks (SVR12) after therapy was evaluated. Results A total of 2 195 articles were retrieved, and 6 articles published in English were eventually included according to the inclusion criteria. The Meta-analysis results demonstrated that the incidence of SVR12 did not significantly differ between the combined RBV and not combined RBV groups (P=0.28). However, the incidence of anemia in the combined RBV group was significantly higher than that in the other group (P < 0.01). Both combined RBV and not combined RBV therapies were efficacious in treating HCV-GT1a and HCV-GT1b subtypes after liver transplantation with similar clinical efficacy (P=0.33). The incidence of SVR in HCV-GT1 recipients did not significantly differ after receiving 12- and 24-weeks therapy after liver transplantation (P=0.95). Conclusions When SOF-based DAAs regimen is adopted to treat HCV-GT1 in recipients after liver transplantation, combination with RBV not only fails to improve the virus clearance rate and bring clinical benefits, but also increases the risk of anemia in the recipients.
