Serum beta-carotene deficiency in HIV-infected children

Area of Science:

• Nutrition Science
• Immunology
• Pediatric Infectious Diseases

Background:

• Symptomatic human immunodeficiency virus (HIV)-infected children often experience nutritional challenges.
• Micronutrient status, particularly antioxidants like beta-carotene, may influence immune response and disease progression in HIV.

Purpose of the Study:

• To compare serum levels of beta-carotene, vitamin A, and vitamin E in symptomatic HIV-infected children versus a healthy control group.
• To investigate the relationship between these micronutrients and the clinical status (presence or absence of Acquired Immunodeficiency Syndrome - AIDS) in HIV-infected children.

Main Methods:

• Cross-sectional study comparing 23 symptomatic HIV-infected children (African-American and Hispanic) with 36 age- and sex-matched uninfected children.
• Nutritional status assessed using body mass index (BMI).
• Serum concentrations of beta-carotene, vitamin A, and vitamin E measured in a subset of HIV-infected children.

Main Results:

• HIV-infected children exhibited a 4.9-fold reduction in serum beta-carotene compared to controls.
• Serum beta-carotene was significantly lower in children with AIDS (13-fold decrease) and without AIDS (6.5-fold decrease).
• No significant differences were found in serum vitamin A or vitamin E levels between the groups.

Conclusions:

• Symptomatic HIV-infected children, despite normal BMI, present with profound serum beta-carotene deficiency.
• This deficiency is more pronounced in children with AIDS.
• The findings suggest potential immunologic and clinical implications for beta-carotene status in pediatric HIV disease progression.
