Pituitary adenylate cyclase-activating polypeptide (PACAP) is a novel bioactive peptide isolated from ovine hypothalamus. Recently, its presence and action have been demonstrated also in peripheral tissues such as testis and ovary. On the basis of sequence similarity, PACAP is included in the vasoactive intestinal peptide (VIP)/glucagon/secretin/growth(More)
BACKGROUND The clinical heterogeneity of polycystic ovary syndrome (PCOS) is mirrored by the unceasing debate on the most appropriate diagnostic criteria. METHODS AND RESULTS To highlight differences and inconsistencies between NIH and ESHRE/ASRM criteria, we applied them to 375 patients with oligo/amenorrhoea and signs of hyperandrogenism. Among them, we(More)
Polycystic ovarian syndrome (PCOS) is frequently characterized by obesity and metabolic diseases including hypertension, insulin resistance, and diabetes in adulthood, all leading to an increased risk of atherosclerosis. The present study aimed to evaluate serum and production of inflammatory markers in adolescent Sardinian PCOS. On the basis of HOMA(More)
In order to test the possible negative effect of corticotropin-releasing factor (CRF) on the pituitary-gonadal axis, two gonadotropin-releasing hormone (GnRH) tests, on two consecutive days, were performed in five normally cycling women in the midluteal phase of the menstrual cycle. The first GnRH test was performed after 2 h during which time basal blood(More)
In order to evaluate the acute insulin response after i.v. injection of glucagon in polycystic ovary syndrome (PCOS), 35 women affected by PCOS and 11 normo-ovulatory controls underwent a 75 g oral glucose tolerance test (OGTT) and, 2 days later, a glucagon test (1 mg i.v.). Patients were analysed according to their degree of obesity; the insulin release(More)
The pituitary and luteal responsiveness of GnRH were studied in 20 normal women at different stages of the luteal phase (LP). Blood samples were collected every 15 min for 180 min before and 120 min after the iv injection of 25 micrograms GnRH. The studies were performed in the early LP (ELP; days 2-3 of LP; n = 5), mid-LP (MLP: days 4-8 of LP; n = 11),(More)
