RESUMO

UNLABELLED: Introduction: We hypothesized that nutritional deficiency would be common in a cohort of postpartum, human immunodeficiency virus (HIV)-infected women and their infants. METHODS: Weight and height, as well as blood concentrations of retinol, α-tocopherol, ferritin, hemoglobin, and zinc, were measured in mothers after delivery and in their infants at birth and at 6-12 weeks and six months of age. Retinol and α-tocopherol levels were quantified by high performance liquid chromatography, and zinc levels were measured by atomic absorption spectrophotometry. The maternal body mass index during pregnancy was adjusted for gestational age (adjBMI). RESULTS: Among the 97 women 19.6% were underweight. Laboratory abnormalities were most frequently observed for the hemoglobin (46.4%), zinc (41.1%), retinol (12.5%) and ferritin (6.5%) levels. Five percent of the women had mean corpuscular hemoglobin concentrations < 31g/dL. The most common deficiency in the infants was α-tocopherol (81%) at birth; however, only 18.5% of infants had deficient levels at six months of age. Large percentages of infants had zinc (36.8%) and retinol (29.5%) deficiencies at birth; however, these percentages decreased to 17.5% and 18.5%, respectively, by six months of age. No associations between infant micronutrient deficiencies and either the maternal adjBMI category or maternal micronutrient deficiencies were found. CONCLUSIONS: Micronutrient deficiencies were common in HIV-infected women and their infants. Micronutrient deficiencies were less prevalent in the infants at six months of age. Neither underweight women nor their infants at birth were at increased risk for micronutrient deficiencies.

RESUMO

Despite an estimated 70,000 Indian children living with HIV infection, little is known about India's pediatric HIV epidemic. Generalizations about epidemiology, natural history, and treatment outcomes from other resource-limited settings (RLS) may be inaccurate for several biologic and social reasons. A review of the Indian literature is needed to optimize country-specific HIV management and examine these generalizations. MEDLINE and EMBASE were searched for articles published in English by November 2007 on HIV-infected, Indian children (0-18 years) that detailed epidemiology, natural history, or treatment. Articles with original, extractable data were selected and summarized using descriptive statistics. Of 370 citations, 58 studies were included in this review (median study size 24 children). Significant heterogeneity was noted among the studies. HIV infection was reported nearly twice as often in males (male/female ratio 1.9) and diagnosed earlier (4.7 years) than in other RLS. Over 2% of hospitalized children were reported to be HIV-infected. The reported mortality among HIV-infected newborns of 22% at 18 months was lower than other RLS. Improved anthropometrics were the only consistently reported and comparable benefit of short-term HAART to other RLS. Review of the Indian literature yielded potentially unique epidemiology and natural history compared to other RLS. However, important questions about the accuracy and representativeness of the Indian data limit its generalizability and comparability. Targeted interventions to curb India's pediatric HIV epidemic require urgent clarification of these findings. If such differences truly exist, management guidelines should be tailored accordingly.
