ABSTRACT
BACKGROUND: Despite the high prevalence of the HIV/AIDS, few studies focused on the prevalence of lipodystrophy in pediatric HIV patients on antiretroviral therapy (ARV) in sub-Saharan African countries. The aim of this study was to assess the prevalence and to identify the risk factors of metabolic disorders related to ARV therapy in this population. METHODS: A cross-sectional study was completed in Kinshasa, the Democratic Republic of Congo. HIV-infected children aged between six and 18 years on ARV were consecutively recruited. For each case, two control children (one non-HIV infected child and one HIV-infected antiretroviral therapy-naïve child) were also recruited. RESULTS: 80 HIV-infected on ARV therapy children (group 1), 80 noninfected children (group 2) and 65 HIV-infected antiretroviral therapy-naïve children (group 3) were recruited. The frequency of lipoatrophy was not statistically different between group 1 (16.3%) and group 3 (21.5%). A significantly higher proportion of lipohypertrophy, hypercholesterolemia, and lactic acidosis was noted in children of group 1, compared to the controls (p<0.05). Mixed form was rarely observed in this series. The frequency of hypertriglyceridemia was not different between the 3 groups (p>0.05). CONCLUSION: Lipohypertrophy, hypercholesterolemia, and lactic acidosis emerge as a frequent metabolic disorders due to ARV therapy.
ABSTRACT
CONTEXT: In Sub-Saharian Africa, the extent of the HIV-related kidney diseases is less known. Even so, that region is supposed to be the epicentre of such complications. This study aimed to determine the prevalence of proteinuria in Congolese children living in Kinshasa and to study its association with the HIV infection. METHODS: By a cross-sectional and multicentric study (in six hospitals of Kinshasa), 194 children were consecutively recruited from August 2008 to February 2009. Among these, 101 naives HIV-infected children and 93 HIV-uninfected children like a control group. Proteinuria was assessed using urine dipstick completed by the 24-hour proteinuria assessment (Esbach method). Determinants of proteinuria were assessed by logistic regression. RESULTS: The median age of all children recruited was 84 months (9-221 months). Concerning the HIV-infected children, the median age was 76 months (9-221 months) with a male/female ratio of 1/1. The prevalence of proteinuria in this group was in order to 23.8%. HIV infected children have seven times more probability to present proteinuria than non infected children (OR 6.9; IC 95%: 2.3-20.8; P<0.001). Important immunosuppression was the main determinant of proteinuria (OR 10.4; IC 95%: 3.34-32.48; P<0.001). CONCLUSION: Proteinuria is common in Congolese children. The HIV infection rises significantly the probability to present proteinuria in children of this study, more so among those with important immunosuppression. This raises the question about the ideal time to initiate HAART in order to reduce the prevalence of kidney injury and to provide the best outcome.
