The Effect of HIV Tat Protein on HCV Replication in an In-vitro Model System
Investigators in the Division of Infectious Diseases and the Departments of Biochemistry and Molecular Biology of The George Washington University Medical Center are carrying out a research study to determine why patients with Human Immunodeficiency Virus (HIV) and Hepatitis C virus (HCV) co-infection (HIV/HCV) have a more rapid and progressive course of HCV infection, leading to fatty infiltration of the liver and cirrhosis.
Human Immunodeficiency Virus (HIV)
Hepatitis C, Chronic
|Study Design:||Observational Model: Case Control
Time Perspective: Cross-Sectional
|Official Title:||The Effect of HIV Tat Protein on HCV Replication in an In-vitro Model System.|
- Laboratory analysis of Tat Protein [ Time Frame: Single sample analysis ] [ Designated as safety issue: No ]The validation that HIV Tat protein is a potent inducer of HCV in dual infected patients will likely lead to anti-tat therapy to manage HCV patients for whom treatment options are rather limited.
|Study Start Date:||July 2010|
|Estimated Study Completion Date:||July 2014|
|Estimated Primary Completion Date:||July 2014 (Final data collection date for primary outcome measure)|
|Detectable HIV RNA and HCV RNA|

Samples will be collected from 4 groups of patients with HIV/HCV infection, identified by the virologic control of either HIV, HCV, or both. Sera will be used in an in-vitro hepatocyte model of hepatitis C infection to better understand the pathogenesis of HIV/HCV co-infection, and to gain insight into intracellular mechanisms.
