Pathogenesis and treatment of human immunodeficiency virus lipodystrophy

Enhanced understanding about the way human immunodeficiency virus (HIV) infects and causes infection in humans has led to invention and use of newer more effective antiretroviral drugs. As treatment for HIV is long term, side effects of the antiretrovirals become an important area of research focus. Antiretrovirals can cause severe metabolic abnormalities, collectively known as HIV lipodystrophy syndrome. If untreated, these metabolic abnormalities have the potential to increase stroke and cardiac ischemia. Management includes choice of nonoffending drugs, switch over to less toxic drugs, hypolipidemics, oral antidiabetics including thiazolidinediones, metformin and growth hormone analogs and finally facial surgeries. Updated knowledge about HIV lipodystrophy, and the hormone-related drugs used to treat it, is essential for physicians and endocrinologists to be able to diagnose the patients and effectively treat them
