Do oestrogen receptors play a role in the pathogenesis of HIV-associated lipodystrophy?
Epidemiological data show an increased risk of HIV-associated lipodystrophy in women, and sex hormone abnormalities have been reported with highly active antiretroviral therapy (HAART). This study, which demonstrates that oestrogen receptor beta expression is significantly reduced in the subcutaneous adipose tissue of HIV-infected lipodystrophic patients, downregulated by HAART regimens including protease inhibitors (PI), and restored after switching from PI, opens perspectives for the investigation of selective oestrogen receptor modifiers for the management of this syndrome.
