Impact of HIV-Associated Inflammation on Disease

Investigator: Steven Deeks, MD
Sponsor: NIH National Institute of Allergy and Infectious Disease

Location(s): United States


My career objectives over the next five years are (1) to recruit and mentor young investigators interested in translational HIV research, (2) to further define the mechanisms and consequences of persistent inflammation during long-term antiretroviral therapy, and (3) to conduct pilot clinical trials aimed at reducing inflammation and/or size of the HIV reservoir during long-term therapy. These goals will be pursued in the context of a multidisciplinary research program aimed at translating basic research findings into the clinic ("translational research") while also collecting biologic specimens from well characterized cohorts for focused laboratory based research (often referred to as "reverse translation"). Specifically, l will conduct a series of studies aimed at determining the complex relationship that exists between HIV persistence (during therapy), chronic inflammation and end-organ function. I will also oversee the conduct of a series of studies aimed at reducing inflammation and/or size of the reservoirs. This work will be funded by a series of grants, including a recently funded U19 whose overall objectives are to investigate the impact chronic inflammation has on HIV persistence during effective therapy. I am seeking to recompete an existing K24. Prior to receiving this K24 grant, I devoted approximately 50% of total effort to clinical care and administrative/teaching responsibilities. The K24 allowed me to focus on mentoring a series of research fellows and junior investigators, many of whom are now independent investigators. If successful, I will continue to devote approximately 25% of my effort to mentoring junior investigators in the conduct of cohort development, translational research and clinical research.

Public health implications: Most HIV infected adults with access to antiretroviral therapy are able to achieve and maintain durable viral suppression with modern antiretroviral drug regimens. Despite effective suppression of HIV replication, many if not most patients exhibit persistent immune dysfunction, which in turn may cause end-organ disease. Also, it is now widely accepted that current therapies are not curative, meaning all HIV infected individuals in need of treatment will have to remain on therapy for many decades. This has significant costs and health implications for those infected with HIV. Efforts aimed at reducing chronic inflammation and/or curing HIV will therefore have long-term benefits for both the global epidemic.
