## Abstract

PROJECT ABSTRACT
The candidate is an Assistant Professor at the University of Maryland School of Medicine in
Division of Infectious Disease and the Institute of Human Virology. The candidate's long-term
goal is to become an independent clinical investigator and to contribute to the field of discovery
in HIV/AIDS and hepatitis C (HCV). The specific focus is on identifying mechanistic pathways
that confer the increased cardiovascular morbidity and mortality with hopes of developing
therapeutic targets to reduce the burden of coronary heart disease (CHD) in these patients.
The candidate has shown initiative by conducting a longitudinal retrospective cohort study of
patients in one of the largest HIV clinics in inner-city Baltimore. Preliminary data demonstrated
an association between chronic HCV infection and elevated risk scores for developing CHD in
this high-risk population. This result led to the hypothesis for the proposed project as well as
another pilot feasibility study evaluating coronary atherosclerosis using coronary CT
angiography in these patients. Two manuscripts have been published, and four others are in
review related to this work.
Rates of CHD are over twice as high in HIV-infected compared to matched uninfected controls,
but factors contributing to increased risk of CHD in HIV-infected patients remain to be clearly
elucidated. Many studies suggest that HCV co-infection is associated with increased rates of
CHD in HIV-infected patients, but results have been mixed. Preliminary data from the
candidate’s work suggest that HCV found an association between HCV and CHD in an inner-
city, high-risk demographic group and therefore provides strong scientific premise to design a
study that will more conclusively delineate this unresolved relationship between HCV and CHD.
The goal of this proposal is to establish the extent to which chronic HCV infection increases the
burden of CHD in HIV-infected patients, and to elucidate host inflammatory and immune
pathways that predict increased CHD burden. We hypothesize that chronic HCV infection in HIV
patients increases CHD risk by inducing inflammation and T cell activation that contribute to
accelerated progression of CHD. To test our hypothesis, we will use novel non-interferon based
therapy to eradicate HCV infection and test whether atherosclerosis decreases, and in doing so,
establish a causal link between HCV and atherosclerosis. Identifying predictors of CHD
progression from overlapping pathways could inform preventive and therapeutic intervention
strategies to mitigate CHD progression in HIV/HCV co-infected patients.
