Sir: Recent evidence suggests that the administration of parenteral hydrocortisone has haemodynamic and prognostic benefits in some patients with septic shock [

3] ACTH stimulation has been widely employed to identify patients that might benefit from corticosteroid replacement therapy. However, the mechanism underlying adrenocortical dysfunction in sepsis, and therefore the question of how best to define it remains to be fully elucidated. More recently the demonstration that ‘total cortisol’ measurements, on which present indices are based, are only poorly correlated with physiologically active ‘free cortisol’ concentrations in hypoalbuminaemic, critically ill patients [
