BACKGROUND Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is caused by tumours releasing ACTH. Ectopic ACTH-producing tumour regression is rarely induced using steroidogenesis inhibitors. We presented a case of EAS in which ACTH production by a lung tumour was reduced by metyrapone (MTP) and also reviewed previous cases of ectopic ACTH production suppressed via steroidogenesis inhibi...
In order to study the mechanism of action of a Met-enkephalin (FK 33824) on the pituitary-adrenal axis eight normal male volunteers were subjected to an ACTH stimulation test. Lysine-vasopressing (LVP), 5 IU, was injected intramuscularly after pretreatment with 0.5 mg FK 33824 i.m. or a placebo. In six of the subjects the opiate was again administered preceding a single injection of 0.25 mg ACT...
Recently, during critical illness, cortisol metabolism was found to be reduced. We hypothesize that such reduced cortisol breakdown may suppress pulsatile ACTH and cortisol secretion via feedback inhibition. To test this hypothesis, nocturnal ACTH and cortisol secretory profiles were constructed by deconvolution analysis from plasma concentration time series in 40 matched critically ill patient...
