Observational Trial of Hepatitis C Virus Infected Patients on Calcineurin Inhibitors

04:20 EDT 22nd May 2013 | BioPortfolio

Summary

Hepatitis C Virus is constantly evolving genetically, particularly in response to the immune system. This is an observational study to examine if immunosuppressants particularly calcineurin inhibitors taken by transplant patients in order to avoid organ rejection causes predictable changes in the genetics of this virus that might be important in order to treat it effectively.

Medical and Biotech [MESH] Definitions

Hepadnaviridae

A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).

Hepatitis A Virus

A species in the genus HEPATOVIRUS containing one serotype and two strains: HUMAN HEPATITIS A VIRUS and Simian hepatitis A virus causing hepatitis in humans (HEPATITIS A) and primates, respectively.

Hepatitis D

INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.

Hepatitis A Virus, Human

A strain of HEPATITIS A VIRUS which causes hepatitis in humans. The virus replicates in hepatocytes and is presumed to reach the intestine via the bile duct. Transmission occurs by the fecal-oral route.

Hepatitis C

INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.

Immune Response to Hepatitis C Virus

The purpose of the study is to investigate the immune response to hepatitis C virus to determine why some people clear the virus and others develop chronic infection. Changes in immune re...

A Phase 1 Study of PPI-668 in Healthy Volunteers and Patients With Hepatitis C Virus (HCV) Genotype 1

PPI-668 is an antiviral agent (a hepatitis C NS5A inhibitor) that is being developed as a potential treatment for hepatitis C virus infection. This study is being done to assess the safet...

Efficacy of Pegylated Interferon Alone in Egyptian Patients With Acute Hepatitis C (ANRS 1213)

Acute hepatitis C is a liver disease related to a virus: hepatitis C virus (HCV). The type of Hepatitis C Virus present in Egypt (genotype 4), has the reputation to respond poorly to treat...

Associations, Outcomes and Genomics of GB Virus C, Hepatitis C Virus and Human Immunodeficiency Virus Infection

The purpose of this study is to examine the effect of GB virus C (GBV-C) on the natural history of chronic hepatitis C virus (HCV) infection in subjects co-infected with HIV and HCV. The o...

Activation of Hepatitis B Virus (HBV) in Hepatitis B Surface Antigen (HBsAg) - Negative But Hepatitis B Core Antibody (Anti-HBc) - Positive Patients

Individuals with resolved hepatitis B, characterized as hepatitis B surface antigen (HBsAg)-negative and hepatitis B core antibody-positive, have latent hepatitis B virus (HBV) infection i...

The Impact of Hepatitis A Virus Infection on Hepatitis C Virus Infection: A Competitive Exclusion Hypothesis.

We address the observation that, in some cases, patients infected with the hepatitis C virus (HCV) are cleared of HCV when super-infected with the hepatitis A virus (HAV). We hypothesise that this phe...

Sexually transmitted infection with an immune-escape mutant hepatitis B virus in an hepatitis B virus-vaccinated individual with acute HIV-hepatitis C virus infection.

Chronic hepatitis E.

The hepatitis E virus is an RNA virus with 4 genotypes. Genotypes 1 and 2 only affect humans and produce epidemic acute hepatitis in endemic regions (Asia and Africa). Genotypes 3 and 4 are considered...

Successful treatment of activated occult hepatitis B in a non-responder chronic hepatitis C patient.

ABSTRACT: We reported a 23 years old male with chronic hepatitis C virus infection, discontinued from pegylated interferon/ribavirin combination therapy due to a lack of early virological response. He...

Fatty liver and hepatitis C virus infection.

Hepatitis C virus infection is a common liver disease worldwide, leading to the development of steatosis, cirrhosis and hepatocellular carcinoma. In patients with chronic hepatitis C virus infection t...
