    The Effect of Endogenous Dehydroepiandrosterone Sulphate on Antibody Response to Hepatitis B Vaccine in Neonates

      Full article (PDF)

      Summary

      Background: DHEAS, the most abundant steroid secreted by the adrenal cortex, is suggested to have an important role in the development of immune reaction by activating T cell function and increasing antibody response, and has been tried as a vaccine adjuvant in elderly people.

      Objectives: We examined the correlation between endogenous DHEAS and antibody response in the neonatal period by comparing the serum DHEAS levels with the amount of antibody response against hepatitis B vaccination in neonates.

      Methods: Vaccine was administered to 12 healthy infants within 24 hours of birth (day 0), and blood specimens were obtained on days 0 and 30 for determination of anti-hepatitis B surface antibody concentration and DHEAS levels.

      Results: DHEAS levels varied widely (range 0.38-3.70 μg/ml, mean±SD 2.14±0.98). While we could identify two groups of patients - those with high DHEAS levels (2.90±0.56) and those with lower levels (1.30±0.56) - there was no correlation between DHEAS levels and the antibody response to hepatitis B vaccine (γ=-0.05).

      Conclusions: In neonates, antibody response to hepatitis B vaccine does not correlate with DHEAS serum levels. These results do not support the usage of DHEAS as a vaccine adjuvant in neonates.
