Abstract. – OBJECTIVE: We aimed to quantitatively evaluate body fat composition in a group of HIV patients treated with Highly Active Anti- retroviral Therapy (HAART) to ascertain both fat loss and fat distribution changes and to identify possible therapeutic and host related associated risk factors. PATIENTS AND METHODS: A total of 180 patients with available total body DEXA scan were assigned to a) Group 1, with clinically evident body fat changes, (BFC) and b) Group 2, without BFC. Clinical and immunovirologic data were collected. We used Student t-test and x2 or Fisher exact test to compare the characteristics of the two groups. Paired t-test was used to compare basal and follow-up data. The relationships between variables were evaluated by calculating Pearson’s correlation coefficient and its significance. RESULTS: HAART duration was significantly (p<0.0001) higher for patients in Group 1 than in Group 2, as well as PI (p<0.02) and NRTI (p<0.002) therapy duration. Current CD4 count and CD4 rise from nadir resulted significantly higher in Group 1 than in Group 2 (p<0.02 and 0.006, respectively). Whole Body Fat (WBF), Peripheral Fat (PF) and Leg (L) fat negatively correlated with PI and NRTI therapy duration, while Trunk Fat (TF)/PF positively correlated with PI and NNRTI duration. No significant correlation was found, instead, with NNRTI therapy duration. At 5-year follow-up, we registered a further increase in TF, Arms (A) and L fat, especially in PI-treated patients. CONCLUSIONS: Body fat changes should always be considered when dealing with HIV-affected patients on HAART. The fat loss seemed to involve mainly peripheral regions, while fat accumulation tendency occurred in the trunk.
