Highly active antiretroviral therapy (HAART) for human immunodeficiency vir
us-1 (HIV-1) and prophylactic therapy for opportunistic infections have inc
reased survival. Adverse effects of HAART include lipid profile alterations
, diabetes mellitus, and fat redistribution. These metabolic and physical c
hanges are called the HIV-associated lipodystrophy syndrome. A link to prot
ease inhibitors has been suggested, and more recently to nucleoside reverse
transcriptase inhibitors and factors related to duration of HIV-1 infectio
n itself.
