OBJECTIVES: To establish the prevalence and quantify the severity of body fat redistribution and dyslipidaemia in HIV-infected men after long-term highly active antiretroviral therapy (HAART) compared with the background population.
METHODS: In a cross-sectional study, we included 87 HIV-infected men who had received HAART for at least 6 years and 34 HIV-negative men. Regional body composition was assessed using dual-energy X-ray absorptiometry. Fasting metabolic parameters were obtained. Associations between regional body fat distribution and metabolic parameters were evaluated.
RESULTS: HIV-infected patients and controls did not differ with regard to height and lean body mass. Compared with controls, HIV-infected men had reduced total fat mass (median 12.3 versus 19.2 kg, P<0.001), limb fat mass (4.3 versus 7.9 kg, P<0.001), and trunk fat mass (6.7 versus 10.8 kg, P<0.001) and higher trunk/limb fat ratio (1.7 versus 1.2, P<0.001). Also, patients without clinical lipodystrophy had reduced amounts of limb and trunk fat. In HIV-infected men, triglyceride levels were higher (2.0 versus 1.2 mmol/L, P<0.001), high-density lipoprotein (HDL)-cholesterol levels were lower (1.2 versus 1.3 mmol/L, P<0.05) and insulin levels were higher (40.8 versus 29.9 pmol/L, P<0.01) than in controls. All adverse metabolic parameters correlated with increased trunk/limb fat ratio, and insulin levels correlated positively with trunk fat mass (P<0.01).
CONCLUSION: Peripheral as well as central fat loss is a general characteristic of HIV-infected men after long-term HAART. Although lipoatrophy was the dominant morphological presentation, the adverse metabolic parameters were mainly associated with the increased ratio of trunk/limb fat.
