HIV Associated Reservoirs and Comorbidities Study (HARC)

The HARC Study establishes a biorepository that allows for collaborative investigation of the neuropathogenic mechanisms of HIV and other infectious diseases. Peripheral blood, cerebrospinal fluid, and neuropsychological testing are obtained from participants of diverse profiles: people living with HIV who may be on or off treatment; individuals exposed to other infectious diseases that might impact the nervous system; and uninfected control participants. Medical, mental health, and demographic data are also collected to understand the biological factors uncovered by our studies in the context of broader factors and to link biological and sociodemographic parameters.

In addition to being used for current research questions, HARC Study samples and data are stored for future use. Through the creation of this repository, we facilitate studies which we hope will provide better understanding of HIV and other infectious diseases, allowing us to better evaluate infectious and immunological responses in the nervous system and to potentially identify markers of disease activity, leading to more complete and effective treatments.
