The Effect of HIV Tat Protein on HCV Replication in an In-vitro Model System - Full Text View

Purpose

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.

Condition
Human Immunodeficiency Virus (HIV) Hepatitis C, Chronic


Study Type:	Observational
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.

Primary Outcome Measures:

Laboratory analysis of Tat Protein [ Time Frame: Single sample analysis ]
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.


Enrollment:	20
Study Start Date:	July 2010
Study Completion Date:	June 2015
Primary Completion Date:	June 2015 (Final data collection date for primary outcome measure)

Groups/Cohorts
Detectable HIV RNA and HCV RNA HIV and HCV co-infected with detectable HIV RNA and HCV RNA
Undetectable HIV and Detectable HCV HIV and HCV infected, HIV RNA Undetectable(treated) and Detectable HCV RNA.
Undetectable HIV and HCV HIV and HCV infected, Undetectable HIV RNA and HCV RNA
Undetectable HCV HCV(mono-infected,) HCV RNA undetectable
Detectable HCV RNA Monoinfected HCV, detectable RNA
Detectable HIV RNA Monoinfected HIV, Detectable RNA

Detailed Description:

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.

Eligibility


Ages Eligible for Study:	18 Years and older (Adult, Senior)
Sexes Eligible for Study:	All
