Prospective evaluation of cystatin C in the assessment of kidney dysfunction and survival in liver transplant candidates.

Kidney dysfunction is associated with decreased survival in liver transplant (LT) candidates, yet serum creatinine (sCr) is a poor surrogate for glomerular filtration rate (GFR) in this population. Serum cystatin C (CysC) may provide a more accurate assessment of kidney function and predict outcomes. We performed a multicenter prospective cohort study of consecutive candidates for LT.

Liver function and portal-systemic shunting quantified by the oral cholate challenge test and risk for large oesophageal varices.

Background: The quantitative HepQuant SHUNT test of liver function and physiology generates a disease severity index (DSI) that correlates with risk for clinical complications, such as large oesophageal varices (LEVs). A derivative test, HepQuant DuO, generates an equivalent DSI and simplifies testing by requiring only oral administration of the test solution and two blood samples at 20 and 60 min.

Aims: Since the DSIs measured from DuO and SHUNT are equivalent, we compared the diagnostic performance for large oesophageal varices (LEVs) between the DSIs measured from DuO and SHUNT tests.

Safety and efficacy of ledipasvir/sofosbuvir with or without ribavirin in hepatitis C genotype 1 patients including those with decompensated cirrhosis who failed prior treatment with simeprevir/sofosbuvir.

Background: Combination therapy of simeprevir (SIM)/sofosbuvir (SOF) is an approved treatment for hepatitis C genotype (gen) 1 with overall SVR12 rate of 85%-95%. The single tablet fixed-dose combination of ledipasvir (LDV)/SOF is also approved for gen 1 with sustained virologic response at 12 weeks (SVR12) rates ≥95%. No data are available on the efficacy of retreatment with LDV/SOF in patients who failed initial treatment with SIM/SOF.

Faldaprevir, pegylated interferon, and ribavirin for treatment-naïve HCV genotype-1: pooled analysis of two phase 3 trials.

Introduction & Aim: Faldaprevir is a potent once-daily (q.d.) hepatitis C virus (HCV) NS3/4A protease inhibitor.

Sofosbuvir and simeprevir in hepatitis C genotype 1-patients with end-stage renal disease on haemodialysis or GFR <30 ml/min.

Background & Aims: Treating chronic hepatitis C (CHC) in patients with end-stage renal disease (ESRD) has suboptimal tolerability and cure rates. Safety and efficacy of sofosbuvir plus simeprevir regimen in CHC-infected patients with ESRD on haemodialysis (HD) or glomerular filtration rate (GFR) <30 ml/min is unknown. We evaluated the safety and efficacy of sofosbuvir and simeprevir in this special patient population.

Open-label study of faldaprevir plus peginterferon and ribavirin in hepatitis C virus genotype 1-infected patients who failed placebo plus peginterferon and ribavirin.

Faldaprevir, a hepatitis C virus (HCV) NS3/4A protease inhibitor, was evaluated in HCV genotype 1-infected patients who failed peginterferon and ribavirin (PegIFN/RBV) treatment during one of three prior faldaprevir trials. Patients who received placebo plus PegIFN/RBV and had virological failure during a prior trial were enrolled and treated in two cohorts: prior relapsers (n = 43) and prior nonresponders (null responders, partial responders and patients with breakthrough; n = 75). Both cohorts received faldaprevir 240 mg once daily plus PegIFN/RBV for 24 weeks.

Dasabuvir (ABT333) for the treatment of chronic HCV genotype I: a new face of cure, an expert review.

Hepatitis C virus (HCV) affects nearly 1.3% of US population and around 2% of people worldwide. It is associated with serious complication of Cirrhosis and Hepatocellular carcinoma leading to significant morbidity and mortality.

Grazoprevir plus peginterferon and ribavirin in treatment-naive patients with hepatitis C virus genotype 1 infection: a randomized trial.

Unlabelled: Grazoprevir (MK-5172, Merck & Co., Inc.) is a selective inhibitor of the hepatitis C virus (HCV) NS3/4a protease.

Efficacy and tolerability of rifaximin in combination with lactulose in end-stage liver disease patients with MELD greater than 20: a single center experience.

Background: Rifaximin is a non-absorbable antibiotic which is approved for the treatment of hepatic encephalopathy (HE) in the United States. Our goal was to retrospectively assess this in patients with very advanced liver disease with our center data.

Methods: Between 2003 and 2010, we examined a total of 286 consecutive patients from our center who were on a combination of rifaximin and lactulose, who had been evaluated or listed as eligible for a liver transplant.

Rifaximin for the treatment of hepatic encephalopathy.

Background: Previous studies suggest that rifaximin is efficacious in the treatment of hepatic encephalopathy.

Objective: To evaluate the efficacy and safety of rifaximin in addition to lactulose in improving hospitalization outcomes in patients with hepatic encephalopathy.

Methods: Hospital records of patients evaluated for liver transplantation at a single center between January 2006 and May 2008 were reviewed.

Assessment of the patient who failed treatment for chronic hepatitis C.

Chronic hepatitis C virus (HCV) infection affects more than 4 million people in the United States and 170 million people in the world, making it a major public health problem. Currently, about one half of the patients undergoing hepatitis C treatment do not experience a sustained viral response. With time, this high nonresponse rate has created a large pool of such patients (nonresponders), many of whom have advanced fibrosis or cirrhosis.
