Patients with Cushing's disease (CD) mainly die because of cardiovascular accidents. The aim of this study was to evaluate whether patients with CD still have increased cardiovascular risk and suffer from premature atherosclerosis once cured. Fifteen patients cured from CD for a long term period (5 yr), 30 sex-and age-matched controls, and 30 body mass(More)
BACKGROUND Whether the withdrawal of treatment in patients with nontumoral hyperprolactinemia, microprolactinomas, or macroprolactinomas is safe and effective has been unclear. We performed an observational, prospective study of cabergoline (a dopamine-receptor agonist) withdrawal in such patients. METHODS The study population included 200 patients--25(More)
Somatostatin analogs (SA) are widely used in acromegaly, either as first-line or adjuvant treatment after surgery. First-line treatment with these drugs is generally used in the patients with macroadenomas or in those with clinical conditions so severe as to prevent unsafe reactions during anesthesia. Generally, the response to SA takes into account both(More)
Adult GH deficiency (GHD) is associated with increased cardiovascular morbidity and mortality due to unfavorable lipid profile, hyperfibrinogenemia, and impairment of cardiac performance. This prospective controlled cohort study evaluated the effects of 12-month GH replacement on lipid profile, fibrinogen levels, cardiac mass by echocardiography, and(More)
UNLABELLED Chronic exposure to hypercortisolism has significant impact on patient's health and health-related quality of life (HRQoL), as demonstrated with generic questionnaires. We have developed a disease-generated questionnaire to evaluate HRQoL in patients with Cushing's syndrome (CS; CushingQoL). OBJECTIVE Validate the CushingQoL questionnaire in(More)
The aim of this study was to correlate dopamine receptors and D(2) isoform expression with the cabergoline effect on alpha-subunit secretion in vitro and tumor mass in vivo in clinically nonfunctioning pituitary tumors. Eighteen patients were subjected to neurosurgery, and a tumor sample was used for dopamine receptor and D(2) isoform expression evaluation(More)
The aim of this prospective study was to evaluate the bone mineral density (BMD) at lumbar spine and femoral neck levels and biochemical parameters of bone turnover in 20 consecutive hyperprolactinemic males before and after an 18-month treatment with different dopamine agonists. Six patients received bromocriptine at a dose of 2.5-10 mg/day; 7 patients(More)
Cardiovascular accidents represent the most important cause of death in patients with Cushing's syndrome. This prospective study aims at evaluating carotid arteries by echo-Doppler ultrasonography and clinical and metabolic markers of atherosclerosis in 25 patients with Cushing's disease (CD) before and after 1 yr of remission. Thirty-two sex- and(More)
To evaluate the prevalence of resistance to cabergoline treatment, we studied 120 consecutive de novo patients (56 macroadenoma, 60 microadenoma, 4 nontumoral hyperprolactinemia) treated with cabergoline (CAB) compared with 87 consecutive de novo patients (28 macroadenoma, 44 microadenoma, 15 nontumoral hyperprolactinemia) treated with bromocriptine (BRC)(More)
BACKGROUND Remission rates of 76, 69.5 and 64.3% have been reported in patients with nontumoural hyperprolactinaemia (NTH), microprolactinoma and macroprolactinoma, respectively, 2-5 years after cabergoline (CAB) withdrawal. OBJECTIVE To report the estimated recurrence rate at 24-96 months after CAB withdrawal and indicate predictors of disease remission.(More)
