Introduction: Pituitary surgery is the first line treatment for most patients with Cushing’s disease (CD) but after failure or recurrence after surgery 3 main strategies can be proposed: medical treatment (MT), a 2 nd pituitary surgery, bilateral adrenalectomy (BA). Pituitary radiotherapy is a 4th strategy, generally combined with one of the 3 others. Medical treatment (MT) emerges as an attractive strategy but there are little data on long-term control after f...

Several cases of pneumocystosis developing after lowering cortisol serum level have been reported, mostly in patients with ectopic Cushing’s syndrome. We report here 2 cases of pneumocystosis which developed after initiation of treatment with metyrapone, one in a patient with Cushing’s disease, and the second in a patient with ectopic ACTH secretion by a prostate endocrine carcinoma. Both cases presented severe Cushing’s syndrome. We then analyzed the periodic s...

When pituitary MRI show a typical imaging of adenoma, it is agreed that transsphenoidal surgery is the reference treatment with remission achieved in about 80% of patients. If MRI is negative or inconclusive, some authors consider that the results of surgery are less successful, and propose medical treatment as a first line therapy, despite a disease control rate between 30 and 70%. Since 1990, our center chose to systematically explore patients with ACTH dependent hypercortic...

Adrenocortical carcinoma (ACC) is a rare malignancy with dismal prognosis. Deregulated microRNA (miRNA) expression has been implicated in ACC aggressiveness. Nevertheless, the mechanisms underlying such deregulations remain unknown. Aberrant Wnt/β-Catenin signaling has been reported in about 40% of ACC and is associated with poor outcome. In the present work, we aimed to investigate the link between constitutive activation of Wnt/β-Catenin pathway and miRNA expressio...

Background: Ketoconazole is a steroidogenesis inhibitor approved in Europe for the treatment of endogenous Cushing’s syndrome (CS) based on retrospective studies published over 3 decades. We present interim data from the first prospective observational, multicenter, international study on ketoconazole, a non-interventional PASS (Post-Authorization Safety study) requested by EMA at the time of registration to confirm ketoconazole good tolerance and effectiveness. This stud...
