Adrenal insufficiency and pregnancy.

INTRODUCTION

Adrenal insufficiency is a disorder characterized by the failure of adrenocortical function because of distorted function of hypothalamic-pituitary- adrenal (HPA) axis. Pregnancy is a state of a physiological glucocorticoid excess as the HPA axis is functioning at a higher level.

PURPOSE OF REVIEW: The aim of the present review was to shed light on current evidence of adrenal insufficiency management during pregnancy, along with maternal and neonatal outcomes.

RECENT FINDINGS: A recent multicenter study under the auspices of the European Network for the Study of Adrenal Tumours (ENSAT) presented real-life data of pregnant women with adrenal insufficiency documenting an increased use of hydrocortisone (or mineralocorticoids when needed according to the level of disorder) replacement treatment, increased rates of caesarean section, preterm delivery and adrenal crises along with peripartum and postpartum complications but no maternal or neonatal fatality. These data were in agreement with those obtained from previously published studies.

CONCLUSION

The limited published evidence is in line with the present guidelines as real-life data did not document any increased fatality among pregnant women or newborns. Prospective data with prolonged follow-up are needed to shed more light on appropriate dose adjustments to avoid the risks of under-replacement or over-replacement of glucocorticoid and/or mineralocorticoid drugs and their sequelae.

SUMMARY: A recent multicenter study by ENSAT presented real-life data of pregnant women with adrenal insufficiency documenting an increased use of hydrocortisone as replacement treatment during pregnancy, along with an increased rate of caesarean section and preterm delivery, adrenal crises, peripartum and postpartum complications but no maternal or neonatal fatality. These data are in agreement with those of a previously published study and also confirm the statements made by the recent guidelines. Prospective data are needed aiming to develop precise therapeutic protocols during each trimester of pregnancy according to the different causes of adrenal insufficiency.
