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.
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.
To compare the sustained virological response (SVR = ribonucleic acid (RNA) - hepatitis C virus (HCV) undetectable at week 24 before end the treatment) in chronic hepatitis C patients genotype 1-4 co-infected with HIV-HCV, treated with Peginterferón alfa-2a (40 KD) 180 µg/week and Ribavirin (2000 mg/day during 4 weeks, follow of 1000-1200 mg/day, according to body weight); versus Peginterferón alfa-2a (40 KD) 180 μg/week and Ribavirin (1000-1200 mg/day, according to body weight). To evaluate the impact to extend the treatment with Peginterferon alfa-2a and Ribavirin to week 72, in SVR of these patients with genotypes 1-4 without rapid virological response (RVR = RNA - HCV undetectable at 4 week).
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 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 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.
Primary objective is to measure sustained viral response given to continuation or prolongation of combined Pegasys&Copegus treatment Secondary objective is to measure histological response given to continuation or prolongation of combined Pegasys&Copegus treatment measured by non-invasive methods
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.
A relatively large proportion of patients with chronic HCV infection have normal or mildly elevated ALT. Many of these patients are not being treated, and are not being sent for a liver biopsy. The present study will determine the ability of Methcetin BreathID Test(MBIT) to detect those patients who will be candidates for anti-viral treatment, as an alternative measure for liver biopsy in decision-making prior to treatment in clinical hepatology.
