Patients with treated adrenal insufficiency (AI) have increased morbidity and mortality rate. Our goal was to improve outcome by developing a once-daily (OD) oral hydrocortisone dual-release tablet more physiological exposure-time cortisol profile. The aim compare pharmacokinetics metabolic between OD the same daily dose of thrice-daily (TID) conventional tablets. We conducted an open, randomized, two-period, 12-wk crossover multicenter trial 24-wk extension at five university hospital...

Abstract Context Aggressive pituitary tumors (APTs) are characterized by unusually rapid growth and lack of response to standard treatment. About 1% 2% develop metastases being classified as carcinomas (PCs). For unknown reasons, the corticotroph overrepresented among APTs PCs. Mutations in alpha thalassemia/mental retardation syndrome X-linked (ATRX) gene, regulating chromatin remodeling telomere maintenance, have been implicated development several cancer types, including neuroendocrine...

Changes observed during adult GH deficiency (GHD) are most often reversed with the administration of recombinant human (rhGH). To avoid daily injections, a long-acting molecule has been obtained by covalent binding polyethylene glycol (PEG) rhGH (PEG-GH), allowing weekly s.c. injections. This study was designed to assess its efficacy and safety, in GHD subjects.This randomized, double-blind, placebo-controlled, multiple-dose, parallel group study. Subjects were recruited from 34 centers. A...
