MICRONUTRIENT LEVELS IN HIV-1-INFECTED CHILDREN

Objective: Micronutrients (zinc, copper, selenium, vitamin A, E, and carotenoids) are essential for the integrity of host defences. This study was designed to determine the prevalence of abnormalities of the micronutrient levels in HIV-1-seropositive children. Design: Prospective study. Setting: The study was performed on HIV-l-infected children at the Paediatric Haematology and Oncology Unit of Toulouse Hospital, France. Patients: Twenty-one children, suffering from HIV-1 infection and 21 control subjects of similar age (2-9 years) were included in the study. In the HIV-1-infected children, two subgroups were considered according to stage (non-AIDS or AIDS), based on the Centers for Disease Control and Prevention 1987 criteria. Results: The first statistically significant deficiencies occurred at non-AIDS stage and were confirmed at AIDS stage: P<0.05 for lycopene, retinol, tocopherol and P<0.001 for transthyretin and serum albumin. Levels of copper (40%) and long-chain polyunsaturated fatty acids (21%) were higher in the non-AIDS group than the controls. Conclusion: Biological impairing of the micronutrient levels was observed in the non-AIDS stage without clinical sign. This information is useful in delineating eventual and well considered nutritional intervention strategies that may improve the clinical status of HIV-1-infected children and perhaps alter the course of their disease.
