Filter by:Percutaneous liver biopsy (PLB) is the gold standard for grading necroinflammation and staging fibrosis in patients with chronic viral hepatitis. Whether the use of 1-deamino-8-D-arginine vasopressin (DDAVP) before PLBs in hemodialysis (HD) patients with chronic viral hepatitis has comparable safety profiles to those with normal renal function (NRF) has not been evaluated in prospective studies.
The prognosis of chronic hepatitis C virus (HCV)infeciton varies from minimal progressive disease to cirrhosis or hepatocellular carcinoma. Host genetic factors contribute to disease severity. It is known that cytokine gene (including tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) polymorphism affect disease prognosis.This study aims to assess the effect of TNF-alpha and IL-10, and their interaction,on prognosis of HCV-related chronic liver disease
Patients with chronic hepatitis C with persistently normal alanine aminotransferase (ALT) levels have been generally excluded from treatment, because the strong conviction that normal ALT would be synonymous of absence of liver damage. However, recent studies have demonstrated marked liver fibrosis, including cirrhosis, in patients with HCV and persistently normal ALT levels. Up to now, just a sigle randomized, controlled, multicenter study was lead to evaluate the efficacy and safety of combined therapy in patients with chronic hepatitis C and persistently normal serum ALT levels. Aim of our study is evaluate the efficacy of treatment and the outcome of treated patients compared with a control group of untreated patients.
Hepatitis C virus (HCV) infection is a global health problem, which may lead to chronic hepatitis, cirrhosis, hepatic decompensation and hepatocellular carcinoma (HCC). Recently, treatment with peginterferon alfa plus ribavirin has become the standard of care for patients with chronic hepatitis C. While genotype 2 patients can have higher sustained virologic response (SVR) rates to 80-90%, genotype 1 patients generally have low SVR rates of only 40-50%. In contrast, genotype 1 Taiwanese patients have superior SVR rates than those in Western countries. Despite the overall improved response to this combination therapy, more than 75% of patients suffer from treatment-related adverse events and the costs remain high, which make individualized therapy of paramount importance to maximize treatment response and minimize adverse events. HCV viral kinetics with interferon-based therapies have been studied recently to evaluate patient responses. Early viral kinetics shown to have favorable SVR rates, which make shorter treatment duration possible. However, different viral kinetics were found through ethnicity. Recently, a pilot study to evaluate the viral kinetics of 6 Taiwanese patients with HCV infection who received peginterferon alfa plus ribavirin therapy has shown superior early viral kinetics to those in Caucasian patients. Based on the favorable SVR rates in treating Taiwanese patients with chronic hepatitis C, the investigators aimed to conduct a large confirmatory study to evaluate the viral kinetics and try to define the optimal treatment for these patients.
The aim of this study is to compare two therapeutical strategies concerning the combination therapy (peginterferon alfa-2a and ribavirin) in naïve patients with chronic hepatitis C of genotype 1. "Reference" strategy corresponding to standards of care recommended by the French consensus conference versus "Test" strategy corresponding to adaptation strategy of ribavirin dose during the first week according to AUC (area under the curve) of ribavirin plasmatic concentration after the first intake (Day 0) of 600 mg
The purpose of this study is to evaluate if the combination of Lpv/r monotherapy and anti-HCV drugs does not match with additional toxicity induced by the association of HAART and Peg-IFN + ritonavir in HIV/HCV coinfected patients. Secondary objective is to assess if Lpv/r monotherapy during HCV-treatment is associated with HIV efficacy versus optimized HAART.
The purpose of the study is to check whether development of depression as a side effect of interferon alpha treatment in chronic carriers of hepatitis C can be prevented by omega-3 fatty acids.
Chronic viral hepatitis C is a frequent liver disease. It is associated with variable degree of hepatic fibrosis. To date, liver histology is still regarded as the gold standard to detect, diagnose and quantify liver fibrosis. This requires to perform a liver biopsy. Severe complications are associated to this procedure in 0.01 to 0.1% of cases. Because of this, the repetition of the biopsy to evaluate the progression of the disease or the response to treatment poses ethical questions. Also, liver biopsy only explore a minimal portion of the liver and liver fibrosis, which is not homogeneous, may be under- or over-estimated. To avoid risks linked to invasive technique and sampling errors associated to liver biopsy, efforts are being made to develop non-invasive technology to detect and quantitate liver fibrosis. In this study we will perform in patients with chronic hepatitis C, serum tests, fibroscan (elastography of liver parenchyma determined by ultra-sounds), and elastography of liver parenchyma by MRI. This study will allow - to determine whether non-invasive tests effectively measure liver fibrosis - to compare each non-invase test with results of liver biopsy - to determine whether a non-invasive test or a combination of non invasive tests may be used to accurately evaluate liver fibrosis in patients with chronic hepatitis C.
Chronic hepatitis C virus (HCV) infection is associated with an increased risk for the development of type 2 diabetes and HCV infection itself may promote insulin resistance, irrespective of the severity of liver disease. Insulin resistance seems to be genotype specific and may play a role in fibrogenesis in chronic hepatitis C. In an “in vitro” model, increased levels of insulin may promote increased HCV replication. RATIONALE Decreased insulin resistance and reduced hyperinsulinemia may facilitate the efficacy of anti-viral drugs on HCV replication.
The objective of this study is to undertake an initial evaluation of the safety, tolerability, antiviral effect, and pharmacokinetics of celgosivir in combination with peginterferon alfa-2b and ribavirin in patients with chronic HCV infection.
