Premature ovarian insufficiency

Christin-Maitre S

Premature ovarian failure or primary ovarian insufficiency (POI) is characterized by amenorrhea occurring before the age of 40-year-old, with elevated gonadotropins (FSH >20 mIU/ml). It affects 1–2% of women. So far, in more than 75% of cases, its etiology remains unknown.The obvious causes are chemotherapy, radiotherapy and ovarian surgery, mainly for bilateral ovarian endometriomas. Genetic causes of POI include rare diseases, such as blepharo...

Illicit expression of membrane receptors for circulating regulatory factors, such as gastric inhibitory polypeptide (GIP), luteinizing hormone (LH) and serotonin (5-HT) receptors, has been well documented in ACTH-independent macronodular adrenal hyperplasias (AIMAHs) causing Cushing’s syndrome. In addition, we have observed an abnormal expression of ACTH in some steroidogenic cells in two AIMAH tissues. The aim of the present study was to investigate the role of local pro...

Context: Ectopic GHRH secretion is a rare cause of acromegaly described mainly in isolated case reports.Setting: From the registry of the sole laboratory performing plasma GHRH assays in France, we identified cases of ectopic GHRH secretion presenting with acromegaly between 1983 and 2008.Patients: In total, 21 patients aged 14–77 years, from 12 French hospitals. Median GHRH was 548 ng/l (270–9779)....

Carotid IMT and stiffness, aortic stiffness and pulse pressure: association with hormone therapy in postmenopausal women: baseline findings from the CASHMERE trial

Simon T , Boutouyrie P , Christin-Maitre S , Gompel A , Joanides R , Kearny-Schwartz A , Kuntz Ch , Laurent S , Pannier B , Pornel B , Struijker-Boudier HH , Thuilliez Ch , Van Bortel L , Zannad F , Pithois-Merli I , Jaillon P

Common carotid artery intima media thickness (CCA-IMT), aortic stiffness (carotid-femoral pulse wave velocity-PWV) and central pulse pressure (PP) are early markers of atherosclerosis. The influence of hormonal replacement treatment (HRT) on arterial parameters in menopausal women remains to be investigated.We used baseline data of 665 menopausal women with hypercholesterolemia, screened for the CASHMERE study, a 12-month double-blind randomized trial co...

Deleterious effects of beta-blockers on arterial stiffness and central pulse pressure in menopausal women: baseline findings from the Cashmere trial

Beta-blockers (BB) may be less effective than other antihypertensive drugs for stroke prevention in patients with primary hypertension (ASCOT and LIFE studies). Our study compares arterial stiffness and central PP between users (BB+) and non users of BB (BB-), among menopausal women with hypercholesterolemia and no history of CV disease.Methods and Results: We used the baseline data of 664 menopausal women, screened for the Cashmere study, a12-month doub...
