Aims: Human corticotrophin releasing hormone (hCRH) stimulation test was used: (i) to determine the relation between pituitary-adrenal response and systemic blood pressure in very low birth weight (VLBW) infants, and (ii) to characterise the endocrinological features of Transient Adrenocortical insufficiency of Prematurity (TAP).
