A Model-Based Illustrative Exploratory Approach to Optimize the Dosing of Peg-IFN/RBV in Cirrhotic Hepatitis C Patients Treated With Triple Therapy

چکیده
Hézode et al. recently reported the frequent occurrence of anemia and thrombocytopenia in the ANRS-CO20-CUPIC cohort of hepatitis C virus (HCV) cirrhotic experienced patients treated with pegylated-interferon (Peg-IFN), ribavirin (RBV), and telaprevir or boceprevir.1,2 Using frequent measurements of serum drug concentrations, hemoglobin, and platelet concentrations obtained in 15 patients of this cohort, we show how an on-treatment model-based approach could be used to individualize dose regimen and avoid the occurrence of RBV-induced anemia and Peg-IFN-induced thrombocytopenia.

Early virological assessment during telaprevir- or boceprevir-based triple therapy in hepatitis C cirrhotic patients who failed a previous interferon based regimen - The ANRS CO20-CUPIC study.
BACKGROUND AND OBJECTIVE To assess within the ANRS CO20-CUPIC cohort whether the viral load (VL) at week 2/week 6 for telaprevir/boceprevir-based triple therapy, respectively, was predictive of sustained virological response (SVR) in patients with hepatitis C virus (HCV) infection and to study the relevance of this measurement to early diagnose drug resistance. METHODS Observational study of ...
متن کاملIncreased Ribavirin Bioavailability Associated With Telaprevir Use in Hepatitis C Patients Treated With PEGylated -Interferon/Ribavirin/Telaprevir Triple Therapy
BACKGROUND Anemia is more frequent in patients receiving telaprevir with PEGylated interferon/ribavirin (PEG-IFN/RBV) than in those receiving PEG-IFN/RBV alone. OBJECTIVES The objective was to measure the impact of telaprevir on RBV bioavailability and to assess the concomitant renal function. MATERIALS AND METHODS Thirty-seven hepatitis C virus (HCV) patients non-responders to a previous c...
متن کاملTelaprevir-based triple therapy for hepatitis C null responders among living donor liver transplant recipients.
Telaprevir (TVR), a direct -acting protease inhibitor, was recently reported to improve treatment efficacy when used in combination with peg-interferon (PEG-IFN) and ribavirin (RBV) as triple therapy for HCV in non-transplant patients. The aim of the present study was to investigate the feasibility of TVR-based triple therapy among Japanese living donor liver transplant (LDLT) recipients who ha...
متن کاملImpact of the Pegylated-interferon and Ribavirin Therapy on the Treatment-related Mortality of Patients with Cirrhosis Due to Hepatitis C Virus
UNLABELLED Although the protease inhibitors have revolutionized the therapy of chronic hepatitis C (CHC), the concomitant use of pegylated-interferon (PEG-IFN) and ribavirin (RBV) is associated to a high rate of adverse effects. In this study, we evaluated the consequences of PEG-IFN and RBV and their relationship with mortality in patients with cirrhosis. METHODS Medical records of CHC who u...
متن کامل1(OH) Vitamin D3 Supplementation Improves the Sensitivity of the Immune-Response during Peg-IFN/RBV Therapy in Chronic Hepatitis C Patients-Case Controlled Trial
OBJECTIVE 1,25(OH)2 vitamin D3 can affect immune cells. However, the mechanism responsible for the favorable effects of 1(OH) vitamin D3, which becomes 1,25(OH)2 vitamin D3 in the liver, is not clear. The aim of this study is to analyze the immunological response of 1(OH) vitamin D3 supplementation in CH-C patients. DESIGN Forty-two CH-C patients were treated with 1(OH) vitamin D3/Peg-IFNα/RB...
