Abstract Highly active antiretroviral therapy (HAART) is associated with metabolic adverse events such as lipodystrophy in human immunodeficiency virus (HIV)-infected patients. The objective of the present study was to evaluate the effects of HAART-associated lipodystrophy on resting energy expenditure and caloric intake. In this cross-sectional study we compared resting energy expenditure (REE) and energy intake in 30 HAART-treated patients with lipodystrophy (HAART+LD+) with 13 HAART-treated patients without lipodystrophy (HAART+LD-). REE was measured using indirect calorimetry, and energy intake was recorded as a 3-day diary of food intake. REE (5,180+/-160 vs. 4,260+/-150 J/min, P<0.01) and also REE expressed per fat-free mass (86+/-1 vs. 78+/-2 J.kg fat-free mass-1.min-1, P<0.01) were significantly higher in the HAART+LD+ than the HAART+LD- group. Rate of lipid oxidation was significantly higher in the HAART+LD+ than the HAART+LD- group. Total energy and fat intakes were significantly increased in the HAART+LD+ compared with the HAART+LD- group. These results imply that HAART-associated lipodystrophy is associated with increased REE and lipid oxidation and with increased caloric and fat intake.
