Background: Following pituitary surgery, dynamic testing with insulin tolerance (ITT) or glucagon stimulation testing (GST) is used to identify patients with secondary hypocortisolism who require glucocorticoids. High glucocorticoid replacement doses are associated with adverse effects, and the optimal replacement dose is unknown.Aim: We aimed to assess the interpretation of dynamic testing post pituitary surgery in clinical practice and its relation wit...

Background: After pituitary surgery patients require HPA axis assessment, that is achieved with postoperative cortisol measurements and, in selected patients whose post-operative cortisol measurements are inconclusive, with the insulin tolerance test (ITT) and the glucagon stimulation test (GST).Aim: We aimed to assess the performance of the day 2/3 post-operative cortisol in predicting the HPA axis sufficiency as assessed by the ITT and the GST.<p c...
