Less is known about the prevalence of absolute adrenocortical insufficiency based on more usual definitions low baseline and corticotropin stimulated cortisol . A study by Wu and colleagues provides convincing evidence that critically ill patients could evolve from a normal adrenal status towards very low cortisol levels within a few days. Although the exact consequences of these findings deserve more investigation adrenal testing should not be omitted in patients not improving their hemodynamic status. In the previous issue of Critical Care Wu and colleagues 1 report delayed adrenal insufficiency in 15 critically ill patients on the basis of a repeated plasma cortisol test among a prospective cohort of 53 patients who had normal or high cortisol levels on first testing and did not exhibit clinical improvement with treatment. Although 11 of these 15 patients received replacement doses of steroids they had a longer length of stay in hospital and longer duration of mechanical ventilation. The authors must be congratulated for these findings which add a new piece in the complex puzzle of adrenocortical function steroid treatment and outcome in the intensive care unit ICU . The renewal of interest for adrenal testing in .
