Cirrhosis risk score of the donor organ predicts early fibrosis progression after liver transplantation.

Background & Aims: Fibrosis progression (FP) after liver transplantation (LT) increases morbidity and mortality. Biomarkers are needed for early prediction of FP. A recipient’s seven-gene cirrhosis risk score (CRS) has been associated with FP, especially in non-transplant cohorts. A broader validation of CRS, including the genotype of the donor-organ and HCV-negative patients is lacking. We therefore analyzed the impact of donor- and recipient-specific genotypes on FP after LT in a large cohort of HCV-positive and -negative patients.Method: Genotyping from liver biopsies (n=201 donors) and peripheral blood (n=442 recipients) was performed. Cirrhosis risk score was correlated with FP at …

Effects of Smoking on Pegylated Interferon alpha 2a and First Generation Protease Inhibitor-based Antiviral Therapy in Naïve Patients Infected with Hepatitis C Virus Genotype 1.


 
 
 
 
 
 Background & Aims: Smoking has multiple effects on factors influencing hepatitis C and antiviral therapy, including lipid metabolism, fibrosis, platelet count and adherence aspects. The aim of this analysis was to determine the impact of smoking on hepatitis C virus antiviral therapy.
 Methods: Data of two cohorts of an observational multicenter study including therapy-naïve patients infected with genotype 1 hepatitis C virus (HCV) treated with dual antiviral therapy (n=7,796) with pegylated interferon alpha 2a in combination with ribavirin, or triple antiviral therapy (n=1,122) containing telaprevir or boceprevir, were analysed.

This analysis evaluated the efficacy and safety of new interferon (IFN)-free direct-acting antiviral (DAA) therapies in a large real-world cohort of HCV patients after LT.Methods: We retrospe…

Urinary ethyl glucuronide (uEtG) as a marker for alcohol consumption in liver transplant candidates: a real-world cohort

 In order to reduce alcohol relapse after liver transplantation (LT), the German national guidelines for waiting-list maintenance and organ allocation demand a minimum 6-month period of alcohol abstinence pre-LT, confirmed by measuring urinary ethyl glucuronide (uEtG). Between January 2015 and June 2016, uEtG was measured at least once in 339 cirrhotic patients with an indication for LT at the University Medical Center Mainz. uEtG was measured with an enzyme-linked immunosorbent assay (ELISA) screening test (cutoff value: 500 µg/L). For uEtG values ≥ 500 µg/L, liquid chromatography-mass spectrometry (LC-MS/MS) was performed as a confirmatory assay. Data were collected prospectively in a tra…
