    Abstract:
    ß-endorphin is a neuropeptide involved in several brain functions: its plasma levels are higher in obese women and its release increases after oral glucose tolerance test (OGTT) in normal or obese women. The study included 46 healthy women and evaluated the effect of oral dehydroepiandrosterone [DHEA] (50 mg/day) in early postmenopausal women (50-55 years) both of normal weight (group A, n = 12, BMI = 22.1 ± 0.5) and overweight (group B, n = 12, BMI = 28.2 ± 0.5), and late postmenopausal women (60-65 years) both normal weight (group C, n = 11, BMI = 22.5 ± 0.6) and overweight (group D, n = 11, BMI = 27.9 ± 0.4) undergone OGTT, in order to investigate if DHEA could restore/modify the control of insulin and glucose secretion and ß-endorphin release in response to glucose load. The area under the curve (AUC) of OGTT evaluated plasma levels of different molecules. DHEA, DHEAS, and ß-endorphin plasma levels were lower in baseline conditions in older women than younger women. Considering the AUC of ß-endorphin response to OGTT, all groups showed a progressive significant increase after 3 and also after 6 months of treatment in comparison to baseline and 3 months of treatment.
