Filter by:Researchers want to see whether Sho-saiko-to (SST) can help in patients with chronic hepatitis C. Chronic hepatitis C may cause swelling within the liver and this can lead to scar tissue. In some patients, severe scarring of the liver, liver failure and liver cancer can occur. Standard treatment for chronic hepatitis C is a drug called interferon with or without another drug called ribavirin. There are a number of side effects that some patients are unable to take. Other patients may have an initial response, but then the virus and the inflammation come back. Sho-saiko-to is an herbal medicine that has been used for many years in Asia to treat liver disease. The purpose of the study is to evaluate whether Sho-saiko-to may improve liver swelling and injury caused by chronic hepatitis C.
The purpose of this study is to evaluate the activity and safety of telaprevir on Hepatitis C Virus (HCV) Genotype 4, alone or in combination with standard therapy, that is, pegylated-interferon-alfa-2a and ribavirin in treatment-naive (never been treated before with antiretroviral therapy) participants.
The purpose of this research study is to test the safety, tolerability, and effectiveness of the drugs Pegasys and Copegus when used for hepatitis C genotypes 6, 7, 8, and 9. Patients are randomly assigned (by chance) to either Treatment Group A (Pegasys and Copegus for 24 weeks) or Treatment Group B (Pegasys and Copegus for 48 weeks).
The purpose of this study is to determine if CTS-1027 can lower elevated liver enzymes in patients with chronic HCV infection.
Interleukin 29 (IL-29) is a substance that is produced in the body to help fight viral infections. The purpose of this study is to test the safety and antiviral effects of PEG-rIL-29 (a man-made form of IL-29) when it is given either by itself at different doses or in combination with the approved dose of ribavirin (an antiviral drug) to subjects with hepatitis C infection who have received no prior treatment for this disease or who have relapsed following previous treatment with PEGylated interferon alpha (PEG-IFN-α), or other form of IFN-α, and ribavirin.
The aim of the study was to verify the influence of Agaricus blazei (Murrill) ss. Heinemann (A. blazei) on the evolution of nutritional state and liver function in hepatitis C patients.
Cirrhosis is a diffuse lesion characterized by architectural distortion of the liver because of collagen deposition and development of nodules of regenerating hepatocytes. It is an irreversible change that results from diseases characterized by chronic liver injury (Fujimoto, 2000). Cirrhosis alters the pattern of blood flow through the liver and results in impaired perfusion of hepatic lobules with intrahepatic and extrahepatic shunting of blood. This deprives hepatocytes of uniform perfusion by arterial and portal venous blood resulting in both portal hypertension and other consequences of cirrhosis including impaired protein synthesis and altered drug metabolism. The histologic diagnosis of cirrhosis requires the presence of regenerative nodules or pseudolobules completely encircled by fibrosis such as congenital hepatic fibrosis can result in portal hypertension in the absence of cirrhosis (Anthony et al., 1977). The events leading to the development of cirrhosis are generally those of chronic injury with hepatocyte destruction. Acute severe liver injury as in fulminant viral hepatitis does not result in cirrhosis and the liver generally returns to normal after recovery. Cirrhosis can be classified by macroscopic appearance, by cause, and by histologic appearance and location of liver damage. Micronodular cirrhosis is composed of uniform nodules less than 3 mm in diameter, whereas macronodular cirrhosis has varying size nodules greater than 3 mm diameter. Mixed nodular cirrhosis has nodules of both sizes. Some liver diseases such as alcoholic liver disease may present as micronodular cirrhosis and develop larger nodules with subsequent regeneration of hepatocytes. For this reason, many prefer etiologic classification (e.g., alcoholic cirrhosis). The designation of cirrhosis as post necrotic, biliary and portal are still commonly used and imply predominant histologic location of fibrosis. Cirrhosis is an irreversible disease, and attempts should be made to stabilize the patient and to control the cause. Factors that indicate a poor outcome include an elevated prothrombin time that does not correct itself with parenteral vitamin K, upper gastrointestinal bleeding caused by varices, ascites refractory to therapy, increased age of the patient, sever malnutrition, spontaneous bacterial peritonitis, a pronounced increase of serum bilirubin in the absence of haemolysis, and heptocellular carcinoma (Yeh et al., 2003). In general, all causes of upper GI bleeding are associated with an increased mortality in patients with cirrhosis. For those with alcoholic cirrhosis who lack portal hypertension, survival is similar to an age-matched cohort if alcohol intake is stopped (Nakamura et al., 1991). If ethanol consumption continues, mortality is higher. Cirrhosis can be present without clinically significant complications and be identified only at autopsy or during evaluation of abnormal liver tests (Mendez et al., 2003). However, for many patients the disease is slowly progressive resulting in one or more complications. The clinical manifestations of cirrhosis are a result of altered hepatic blood flow through the liver with intrahepatic shunting causing impaired perfusion of hepatocytes or portal hypertension with shunting of blood around the liver though portosystemic communications. The major complications of portal hypertension include oesophageal or gastric varices, ascites, portosystemic encephalopathy, and hepatorenal-syndrome (Menon & Kamath, 2000). With impairment of hepatocyte perfusion or reduction of hepatocyte number, altered synthetic function can result in hypoalbuminemia, hypoprothrombinemia, and changes in drug metabolism. Vitalliver is a Chinese medicine which is administered in the form of a suppository, which is uncommon for most Chinese medicines. Medications released from the suppositories are absorbed directly from the circulation around the rectum and then reach the liver via the portal vein. Basic pharmacological studies have shown that Vitalliver has good immunomodulating functions, increases the activities of T-cells, B-cells and NK cells, therefore this formulation may have special values in treating liver diseases.
The purpose of this study is to investigate how efficient TMC435350 will work against the Hepatitis C virus genotype 1 (genotypes refer to the genetic constitution of the virus) and what the concentrations of TMC435350 in the blood are with or without pegylated interferon alpha-2a (PegIFNa-2a) or PegIFNa-2a plus ribavirin.
The purpose of this study is to assess the effect of telaprevir on early hepatitis (inflammation of the liver) C virus (HCV) viral kinetics in treatment-naive participants who are chronically (lasting a long time) infected with genotype 2 or 3 HCV.
Insulin resistance is known to adversely effect viral response to treatment in hepatitis C patients We are aiming to study the effect of an insulin sensitizer, metformin, in viral response of hepatitis C to treatment with pegylated interferon and ribavirin in a double blind randomized controlled trial
