Effect of high-dose vitamin A supplementation on the immune response to Bacille Calmette-Guerin vaccines
(2007) In American Journal of Clinical Nutrition 86(4). p.1152-1159- Abstract
- Background: Vitamin A supplementation (VAS) at birth has been associated with decreased mortality in Asia. Bacille Calmette-Guerin (BCG) vaccine is given at birth in tuberculosis-endemic countries. Previous studies suggest that VAS may influence the immune response to vaccines. Objective: Our objective was to examine whether VAS influences the immune response to simultaneously administered BCG vaccine. Design: Within a randomized trial of 50 000 IU vitamin A or placebo Given with BCG vaccine at birth in Guinea-Bissau, 27 10 infants were examined for BCG scar formation and delayed-type hypersensitivity (DTH) to purified protein derivative of Mycobacterium tuberculosis (PPD) at 2 and 6 mo of age. The ex vivo cytokine response to PPD was... (More)

Objective: Our objective was to examine whether VAS influences the immune response to simultaneously administered BCG vaccine. Design: Within a randomized trial of 50 000 IU vitamin A or placebo Given with BCG vaccine at birth in Guinea-Bissau, 27 10 infants were examined for BCG scar formation and delayed-type hypersensitivity (DTH) to purified protein derivative of Mycobacterium tuberculosis (PPD) at 2 and 6 mo of age. The ex vivo cytokine response to PPD was measured in 607 infants. Results: At 2 mo of age, 39% (43% of the boys and 34% of the girls) responded to PPD. The prevalence ratio of a measurable PPD reaction for VAS compared with placebo recipients was 0.90 (95% CI: 0.80, 1.02) for all infants. 0.81 (95% CI: 0.69, 0.95) for boys, and 1.04 (95% CI: 0.86, 1.26) for girls. At 6 mo of age, 42% of the infants responded to PPD. No difference was observed between VAS and placebo recipients. The prevalence of BCG scar was not affected by VAS. The ex vivo interferon-gamma response to PPD was increased by VAS (means ratio: 1.40: 95% CI: 1.03, 1.91). Conclusions: VAS with BCG vaccination does not appear to interfere with the long-term immune response to BCG. However, VAS temporarily altered the DTH reaction to PPD in boys at 2 mo of age, suggesting sex differences in the immunologic response to VAS Given with BCG. This trial was registered at www.clinicaltrials.gov as #NCT00168597. (Less)
