title: Pharmacologic therapy for HIV-associated lipodystrophy.
abstract: OBJECTIVE
  To evaluate the efficacy and safety of pharmacologic therapy in the treatment of HIV-associated lipodystrophy, with a focus on the treatment of fat redistribution. Drug therapies that have been shown to be beneficial in other forms of lipodystrophy and are currently being evaluated in HIV-associated lipodystrophy are also discussed.
  
  
  METHODS
  A MEDLINE search was conducted from 1996 to February 2003. Bibliographies of all articles were reviewed and pertinent articles were included. Abstracts from major meetings in 2002 and 2003 were also reviewed.
  
  
  METHODS
  All published studies were included in the review.
  
  
  RESULTS
  Lipodystrophy has become more prevalent in patients with HIV. Lipodystrophy consists of adipose redistribution and metabolic abnormalities including dyslipidemia and insulin resistance. Treatment of lipodystrophy has been directed at either decreasing the amount of visceral adipose tissue (VAT), dorsocervical adipose tissue (commonly known as buffalo hump) and/or increase subcutaneous adipose tissue (SAT). Recombinant human growth hormone (rhGH) decreases VAT and buffalo hump, although it has been associated with a high frequency of adverse effects. Metformin and the thiazolidinediones have favorable metabolic effects, but were not found to be effective in correcting body compositional changes associated with lipodystrophy. Anabolic steroids and l-carnitine are not effective in the treatment of lipodystrophy.
  
  
  CONCLUSIONS
  No drug therapy exists to fully ameliorate or correct the cosmetic changes of HIV-associated lipodystrophy. Clinicians must weigh the benefits and risks of each agent and individualize treatment for each patient.
