Body Composition Changes and Predictors of Lipodystrophy in a Cohort of Pre-pubertal HIV- infected Children
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2015, Vol 8, Issue 7
Abstract
Aim: To evaluate body composition changes in HIV-infected patients and to identify the predictors of lipodystrophy over time. Methods: A cohort study, evaluated over two and a half years (Time 1: T1; Time 2: T2), including prepubertal HIV-infected children of both genders, between 7-12 years of age. Patient’s data such as transmission, use of prophylaxis for vertical HIV transmission, clinical and immunological classification of disease and current antiretroviral therapy were derived from the medical records. At T1, only subjects with pubertal stage 1 were included. Clinical, anthropometric, body composition and biochemical data were assessed. Patients were divided into two groups: with (LD+) and without lipodystrophy (LD-). Results: A total of 40 patients were enrolled, and 35 patients completed the study. Mean (SD) age was 9.6 (1.1) and 11.6 (1.2) years at T1 and T2, respectively. At T2, 16 (45.7%) children remained prepubertal. LD+ group (n = 8) showed a higher prevalence of short stature (p = 0.008) in T1; higher insulin (p = 0.010) and HOMA-IR (p = 0.013) and reduction of triceps skinfold thickness (p = 0.026) at T2. In both times, we observed lower concentrations of HDLc (p = 0.027), higher values of trunk to arm ratio (p = 0.002, p = 0.001) and lower values of limb to trunk ratio (p = 0.001) and gynoid fat (p= 0.001) in LD+ group. At T1, predictors of lipodystrophy were short stature (OR = 46.198, p = 0.019) and limb to trunk ratio (OR = 0.00009, p = 0.011); in T2, waist circumference (OR = 1.199, p = 0.025) and HDLc (OR = 0.835, p = 0.015). Presence of lipodystrophy was determinant of high insulin levels at T2. Conclusion: In a short period, LD+ group had significant changes in body fat distribution and also biochemical alterations associated to lipodystrophy syndrome.
