Introduction: The 250 μg cosyntropin stimulation test (CST) is used to diagnose non-classic congenital adrenal hyperplasia (NCCAH). The current recommendation to perform CST is when follicular morning 17-hydroxyprogesterone (17OHP) is higher than 6 nmol/l, and CST is considered positive for NCCAH diagnosis when the 60-minutes post-CST 17OHP serum level is above 30 nmol/l. These cut offs are mainly derived from radioimmunoassay (RIA) data. Recently, a validated enzyme-link...

Background: The management of adjuvant mitotane therapy in patients with adrenocortical carcinoma (ACC) is challenging. Plasma mitotane concentrations>14 mg/l have been associated with efficacy in the treatment of advanced ACC; however, data in the adjuvant setting are mixed. Moreover, there is no consensus on how to assess the optimal exposure to mitotane and all the proposed methods have inherent limitations. We have recently proposed a new method analogous to what is es...
