The use of supra-physiological, exogenous corticosteroids in pregnancy may lead to neonatal adrenal suppression. We report on a single-center, case series study carried out between 2006 and 2014, which included all newborns (n = 16) of mothers using prednisolone >= 10 mg/day during pregnancy. Newborns were routinely assessed according to hospital protocol, with follow-up until 6 weeks after birth. We investigated the clinical symptoms and biochemical findings of adrenal suppression occurring in the newborns. Mean dose of maternal prednisolone was 29.7 +/- A 16.1 mg/day with a mean duration of 18.4 +/- A 15.4 weeks. Five newborns showed hypoglycemia with normal serum cortisol concentrations and urinary steroid profiles. Two newborns had abnormal urinary steroid profiles, probably the result of prematurity, but with adequate adrenal stress response during clinical sepsis.
Conclusion: In this retrospective case series, we found no evidence of prolonged effects of maternal prednisolone use during pregnancy on the neonatal hypothalamic-pituitary-adrenal axis.
