Eva Lee, professor in the H. Milton Stewart School of Industrial and Systems Engineering and director of the Center for Operations Research in Medicine and Healthcare, is leading the systems modeling and predictive analysis components of a study investigating the biochemical mechanisms behind cocaine and anti-retroviral drug interactions in mouse models of AIDS.
Researchers agree cocaine injures the heart and predisposes users to HIV/AIDS because of risky behaviors. What’s more, the anti-retroviral medicines used to treat HIV/AIDS also may adversely affect the cardiovascular system. Used together, cocaine and anti-retroviral therapy can amplify the injury from each. Lee is working with cardiac pathologist William Lewis, who is the principal investigator of the study and a professor of pathology and laboratory medicine in Emory University School of Medicine.
For her part, Lee says that “the model must be capable of incorporating large amounts of heterogeneous data, including genomic, biochemical, physiological and pathological.” Continuing, she states that “identifying the discriminatory features and constructing the predictive systems network will offer fundamental understanding of cocaine, HIV/AIDS and antiretroviral nucleosides interaction at multiple levels.” Lee is encouraged that “this will shed light on promising avenues for improving treatment strategies.”
It is estimated that more than 34 million Americans have used cocaine and more than 1.5 million are habitual users. Meanwhile, more than a million Americans are infected with HIV or have full-blown AIDS.
The study is being funded through a new $5.7 million grant from the National Institute on Drug Abuse of the National Institutes of Health.
