LDV/SOF therapy is highly effective and safe in elderly Japanese patients with HCV GT1, even in the presence of cirrhosis or NS5A RASs. Patients with SVR may have a lower risk of HCC.
Background and aimThis study aimed to elucidate whether interferon (IFN)-free direct-acting antiviral (DAA) therapy for hepatitis C after curative treatment of hepatocellular carcinoma (HCC) promotes HCC recurrence in a real-world large-scale cohort.MethodsThis multicenter study was conducted by the Japanese Red Cross Hospital Liver Study Group. This retrospective study analyzed 516 patients who underwent antiviral treatment for hepatitis C with either IFN (n = 148) or IFN-free DAA (n = 368) after curative HCC treatment; 78 IFN-treated patients and 347 IFN-free DAA-treated patients achieved sustained virological response (SVR). The recurrence rate of HCC was compared between the antiviral therapies. Logistic analysis and Cox proportional hazards analysis identified factors associated with early recurrence of HCC within 24 weeks of antiviral therapy and recurrence throughout the observation period, respectively.ResultsAFP at the completion of antiviral therapy, clinical stage of HCC, and non-SVR were independent factors associated with early recurrence of HCC. Among patients who had achieved SVR, the clinical stage of HCC and the level of AFP at completion of antiviral therapy were independent factors associated with early recurrence of HCC. For recurrence throughout the observation period in SVR patients, AFP at completion of antiviral therapy, duration between last HCC treatment to antiviral therapy, and the number of treatments were independent factors. There was no significant difference in the rate of early recurrence of HCC or recurrence throughout the observation period between IFN and IFN-free DAA treated patients.ConclusionsThere were no differences in the early recurrence rate of HCC between patients who underwent IFN and those who underwent IFN-free DAA as antiviral therapies.
Background: Patients with chronic hepatitis C are often complicated by chronic kidney disease (CKD).Aim: To evaluate the efficacy, safety and pharmacokinetics of glecaprevir/pibrentasvir in patients with severe renal impairment.
Methods:In a prospective, multicentre study involving 35 medical institutions, 832 genotype 1-3 patients were treated with glecaprevir/pibrentasvir. The efficacy and safety of glecaprevir/pibrentasvir were analysed for patients with CKD stage 4 or 5.Multivariate analysis was performed to identify the factors associated with the most frequently observed adverse event. In patients undergoing haemodialysis, a pharmacokinetic study was conducted to investigate the dialysability of the drugs: plasma samples were obtained from the arterial and venous sides of a dialyser to serially measure drug concentrations.
Results:The subjects comprised 141 patients (32 with CKD stage 4 and 109 with CKD stage 5), of whom 100 were undergoing haemodialysis. All but one stage 5 CKD patients undergoing haemodialysis achieved sustained virologic response (99.3%). Adverse events were observed in 39.7% of subjects: pruritus was the most frequent (30.5%), and was significantly associated with haemodialysis. In the pharmacokinetic study, no arterial-venous differences in the plasma concentrations of glecaprevir/pibrentasvir were detected during the haemodialysis sessions.Masanori Atsukawa, Akihito Tsubota and Hidenori Toyoda contributed equally to the preparation of this manuscript.

Laparoscopic surgery following CRT was safe and feasible. A shorter anal verge was associated with a longer operation time. Blood loss increased in cases with high CTV, but this can likely be mitigated by experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
