We evaluated the CSF levels of beta-lipotropin (beta-LPH), beta-endorphin (beta-EP) and ACTH, which are three neuropeptides expressed by the same gene encoding for pro-opiomelanocortin, in various groups of demented patients including degenerative (presenile and senile Alzheimer-type dementia, ATD) and vascular (MID) forms. Twelve sex- and age-matched subjects were taken as controls. Our data indicate that ACTH levels are significantly reduced both in ATD and MID patients, while beta-EP and beta-LPH are significantly reduced only in ATD. The low CSF ACTH levels can be considered typical of all demented processes (both degenerative and vascular), while the reduction of beta-EP and beta-LPH in CSF could be due to a degenerative process of CNS.

Abstract
We evaluated the CSF levels of beta-lipotropin (beta-LPH), beta-endorphin (beta-EP) and ACTH, which are three neuropeptides expressed by the same gene encoding for pro-opiomelanocortin, in various groups of demented patients including degenerative (presenile and senile Alzheimer-type dementia, ATD) and vascular (MID) forms. Twelve sex- and age-matched subjects were taken as controls. Our data indicate that ACTH levels are significantly reduced both in ATD and MID patients, while beta-EP and beta-LPH are significantly reduced only in ATD. The low CSF ACTH levels can be considered typical of all demented processes (both degenerative and vascular), while the reduction of beta-EP and beta-LPH in CSF could be due to a degenerative process of CNS.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
