ABSTRACT
This cross-sectional study aimed to compare growth, nutritional status and body composition outcomes between a group of 94 HIV-infected children and adolescents on antiretroviral therapy (ART) and 364 healthy controls, and to evaluate their association with clinical and lifestyle variables within the HIV-infected group. When compared with the control group, HIV patients had higher risk of stunting (odds ratio [OR] 5.33, 95% confidence interval [CI]: 2.83-10.04) and thinness (OR 4.7, 95% CI: 2.44-9.06), higher waist-to-hip ratios (medians 0.89 versus 0.82 for boys and 0.90 versus 0.77 for girls, P < 0.001), and lower prevalence of overweight or obesity (OR 0.33, 95% CI: 0.14-0.78). Protease inhibitor usage was associated with thinness (OR 3.51, 95% CI 1.07-11.44) and lipoatrophy (OR 3.5, 95% CI 1.37-8.95). HIV-infected children on ART showed significant nutritional status and body composition abnormalities, consistent with the severity of vertical HIV infection and the consequences of prolonged ART.

OBJECTIVE: Hypergammaglobulinemia is an early manifestation of perinatal HIV infection. Our objective was to analyze the differences in serum immunoglobulin levels between infected and seroreverter children and their association with clinical outcome. METHODS: We carried out a historical prospective study with 107 infected and 90 seroreverter children. We compared the IgA, IgG, and IgM levels between infected and seroreverters in the first 18 months of life; IgA, IgG, and IgM as surrogate markers of infection; and IgA, IgG, and IgM levels in the first 5 years in infected children, according to clinical outcome. The Mann-Whitney test was used for comparison between groups. Surrogate markers were assessed according to sensitivity, specificity, positive and negative predictive values, and J index. RESULTS: Infected children, when compared to seroreverters, showed significantly higher levels of: IgM from the 1st to the 5th trimester; IgA and IgG from the 2nd to the 6th trimester (P /= 90 mg/dl in the 2nd trimester and IgG >/= 1,700 mg/ dl or 1,200 mg/dl in the 2nd and 3rd trimesters were associated with HIV infection with J indexes of 0.97, 0.92, and 0.93, respectively. Infected children in the B and C categories, compared to those in the N and A, showed higher levels of IgM from the 2nd to the 4th year, and IgA from the 3rd to the 5th year (P
