Pablo Tebas, M.D.

Dr. Pablo Tebas directs the adult AIDS Clinical Trials Unit (ACTU) of the University of Pennsylvania. His main research interests are the treatment of HIV infection and the study of the metabolic complications associated with HIV infection and its treatment. The introduction of highly active antiretroviral therapy (HAART) has resulted in significant reductions in the morbidity and mortality associated with HIV infection. Unfortunately, the use of HAART has also been associated with significant adverse effects, including dyslipidemia and insulin resistance, bone disease and fat redistribution. Current studies are directed to understand better the mechanisms of these complications and prevent their development. Current outpatient and inpatient clinical activities center in the Hospital of the University of Pennsylvania where he follows general ID and HIV infected patients.
