Adrenocortical function during prolonged critical illness and beyond: a prospective observational study.

ABSTRACT:

Purpose

For patients suffering from prolonged critical illness, it is unknown whether and when the hypothalamus-pituitary-adrenal axis alterations recover, and to what extent adrenocortical function parameters relate to sepsis/septic shock, to clinical need for glucocorticoid treatment, and to survival.

Methods

Patients still in ICU on day 7 (N = 392) and 20 matched healthy subjects were included. Morning blood and 24-h urine were collected daily and cosyntropin tests (250 µg) performed weekly, repeated 1 week after ICU discharge on the regular ward.

Results

In all patients free of glucocorticoid treatment up until ICU day 28 (N = 347), plasma ACTH always remained low/normal, whereas free cortisol remained high (P ≤ 0.002) explained by reduced binding proteins (P ≤ 0.
