What is the Meaning of HIV-Associated Lipodystrophy?

HIV-Associated Lipodystrophy is a complex metabolic syndrome characterized by a significant, abnormal redistribution of body fat, often accompanied by dyslipidemia and insulin resistance, occurring in individuals with HIV infection. This condition manifests as either lipoatrophy, the loss of subcutaneous fat, or lipohypertrophy, the accumulation of visceral or dorsal fat, severely impacting body image and cardiovascular wellness. It represents a chronic, multi-systemic complication of both the viral infection and its historical antiretroviral treatments.

What is the Origin of HIV-Associated Lipodystrophy?

The name is descriptive, linking the cause, "HIV," with the condition, "lipodystrophy," which is derived from the Greek lípos (fat) and dys (bad or abnormal) trophḗ (nourishment). This clinical syndrome was first recognized and formally defined following the widespread use of certain classes of antiretroviral therapy, particularly thymidine analog nucleoside reverse transcriptase inhibitors.

What is the Mechanism of HIV-Associated Lipodystrophy?

The underlying mechanism is multifactorial, involving direct mitochondrial toxicity from some antiretroviral drugs, chronic inflammation induced by the persistent viral presence, and alterations in adipokine and growth hormone signaling. These factors lead to impaired adipogenesis, increased lipolysis, and a shift in fat distribution. The resulting visceral adiposity and peripheral fat loss contribute to a pro-inflammatory state and metabolic derangements, necessitating targeted therapeutic interventions.
