Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hepatitis C is a disease of the liver caused by the Hepatitis C Virus (HCV). Patients with hepatitis C may feel well and show no signs or symptoms of being ill. However, researchers would like to study the long-term effects of this disease.

Volunteer blood donors diagnosed with chronic hepatitis C viral (HCV) and various levels of liver enzyme activity will be offered a complete medical evaluation and liver biopsy. The tests will enable researchers to provide the patients with an idea of how severe their liver disease is. The virus and patient will be studied in order to understand why patients with hepatitis C develop different levels of liver damage.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A selected sample of volunteer blood donors with chronic hepatitis C viral (HCV) infection and various levels of serum aminotransferase activity will be offered a complete medical evaluation and liver biopsy to determine the severity of their liver disease. Various virological and host factors will be studied in an attempt to determine why patients with HCV infection develop differing degrees of liver disease.
