Twenty-four subjects (12 patients with major depressive disorder and 12 controls matched for sex and age) received 100 micrograms synthetic human corticotropin-releasing hormone (hCRH) as an iv bolus dose. Healthy subjects exhibited a slight, but sustained, increase of plasma delta sleep-inducing peptide (DSIP) concentrations, whereas a marked reduction of DSIP levels was found in depressives. Compared to controls, depressed patients showed a significant attenuation of corticotropin (ACTH) responses, whereas cortisol secretion in response to hCRH was normal. Basal DSIP and cortisol concentrations were highly correlated and were higher in depressives than in controls. Both were negatively correlated with the DSIP responses to hCRH. These findings are compatible with the hypothesis that hypothalamic-pituitary-adrenal (HPA) overactivity in the depressive state is primarily due to central hypersecretion of CRH and support the view of a modulatory function of DSIP in the complex regulatory mechanism of the HPA system and of its pathophysiological significance for aberrant HPA axis function in major depressive disorder.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D003346 Corticotropin-Releasing Hormone A peptide of about 41 amino acids that stimulates the release of ADRENOCORTICOTROPIC HORMONE. CRH is synthesized by neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, CRH stimulates the release of ACTH from the PITUITARY GLAND. CRH can also be synthesized in other tissues, such as PLACENTA; ADRENAL MEDULLA; and TESTIS.

D003701 Delta Sleep-Inducing Peptide A nonapeptide that is found in neurons, peripheral organs, and plasma. This neuropeptide induces mainly delta sleep in mammals. In addition to sleep, the peptide has been observed to affect electrophysiological activity, neurotransmitter levels in the brain, circadian and locomotor patterns, hormonal levels, psychological performance, and the activity of neuropharmacological drugs including their withdrawal.

D006854 Hydrocortisone The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.

D000324 Adrenocorticotropic Hormone An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
