Additional attention to combination antiretroviral therapy-related lipodystrophy

The occurrence of lipodystrophy in patients taking anti-human immunodeficiency virus (HIV) medications is a serious problem as it is irreversible even after drug withdrawal. Although it was first recognized in patients taking proteinase inhibitors, other types of anti-HIV agents can also cause lipodystrophy. In a recent publication by Jones et al entitled "Highly active antiretroviral therapy dysregulates proliferation and differentiation of human pre-adipocytes" in World Journal of Virology, it was reported that simultaneous treatment of human subcutaneous adipocytes with anti-HIV drugs with different mechanisms of action synergistically exerted anti-adipogenesis effects in vitro, warning us to take utmost care in every case receiving combination antiretroviral therapy (cART). For elucidation of the molecular basis for cART-related lipodystrophy, multi-faceted approaches should be taken, based on a deeper understanding of the development and organization of adipose tissues.
