Efficacy and safety of glecaprevir/pibrentasvir as retreatment therapy for patients with genotype 2 chronic hepatitis C who failed prior sofosbuvir plus ribavirin regimen.

Aim: Rescue therapy for patients with genotype 2 (GT2) chronic hepatitis C who failed prior sofosbuvir (SOF) plus ribavirin (RBV) awaits establishment. This study aims to investigate the efficacy and safety of the fixed-dose combination of glecaprevir (300 mg)/pibrentasvir (120 mg) (GLE/PIB) for patients with GT2 chronic hepatitis C.

Methods: In this nationwide observational study undertaken by the Japanese Red Cross Liver Study Group, 28 GT2 patients with prior failure of SOF + RBV were retreated with GLE/PIB for 12 weeks.

Real-world efficacy and safety of ledipasvir and sofosbuvir in patients with hepatitis C virus genotype 1 infection: a nationwide multicenter study by the Japanese Red Cross Liver Study Group.

Background: We aimed to describe the real-world efficacy and safety of combination therapy with ledipasvir and sofosbuvir (LDV/SOF) for chronic hepatitis C virus (HCV) genotype 1 (GT1) infection.

Methods: This retrospective analysis of a prospective, nationwide, multicenter registry included GT1-infected patients treated with LDV/SOF for 12 weeks. We assessed the rate of sustained virological response at 12 weeks post-treatment (SVR12), incidence of adverse events, and serum markers of hepatocellular carcinoma (HCC).

[A case of splenic artery aneurysm simulating a pancreas tumor].

A 46-year-old man was admitted to our hospital for further evaluation of a hypoechogenic mass in the pancreatic body. He had no history of hypertension, pancreatitis, abdominal trauma, or portal hypertension. He had no abdominal symptoms.

Early decrease in serum IV-7S levels during IFN treatment predicts anti-fibrogenic effect in nonresponders with chronic hepatitis C.

Background: We evaluated whether early changes in serum levels of fibrogenic markers during interferon (IFN) treatment can predict long-term anti-fibrogenic effects in patients with chronic hepatitis C (CHC).

Methods: We retrospectively examined the serum levels of N-terminal peptide of type III procollagen (P-III-NP) and 7S domain of type IV collagen (IV-7S) in 56 patients with CHC who were revealed to be IFN-nonresponders. We measured these markers before (T0) and 1 month (T1) after the commencement of IFN therapy, at the end of 24 weeks' IFN therapy (T24), and 1 year (T24-1) and more than 2 years (T24-2) after the cessation of IFN therapy.

High-dose interferon-alpha therapy lowers the levels of serum fibrogenesis markers over 5 years in chronic hepatitis C.

We examined the levels of serum N-terminal peptide of type III procollagen (P-III-NP) and the 7S domain of type IV collagen (IV-7S) as fibrogenesis markers in patients with chronic hepatitis C to clarify whether high-dose interferon-alpha (IFN-alpha) therapy has a suppressive effect on hepatic fibrogenesis for a long period (over 5 years) after the cessation of IFN therapy. Eighty patients with CHC were given 10 million units of IFN-alpha2b daily for 14 days followed by three times per week for a total of 24 weeks. Patients were divided into the following three groups according to the highest serum alanine aminotransferase levels during 1 year observation after the end of IFN therapy: complete responders (CR), partial responders (PR), and nonresponders (NR).
