Interpretation of Neonatal Adrenal Function Results and Adrenal Function Results in Critical Illness.

Abstract

Adrenal insufficiency (AI) is a life-threatening disorder. Defects at any level of the hypothalamic-pituitary-adrenal axis can impair adrenal function. It is difficult to make a diagnosis of AI in the newborn because during the neonatal period clinical findings are not specific and range from insidious, nonspecific complaints to circulatorycollapse due to hypovolemic shock. Another condition when is difficult to make a diagnosis of AI is in critically ill patients. There is no consensus on which patients to test for AI, which tests to use and how to interpret them. In this evidence-based review we aim to provideinformation for the evaluation of adrenal function results and findings in both the neonatal period and critical illness in childhood and adolescence.
