The aim of the present study was to evaluate the effects of three different anti-androgenic drug-therapy regimens, Diane 35 (cyproterone acetate (CPA) [2 mg] and ethinyl estradiol [35 microg]) plus CPA, Diane 35 plus spironolactone, and spironolactone alone, in patients with hirsutism. In this prospective, randomized clinical study, 79 subjects with idiopathic hirsutismus were studied. The pati...

The psychological symptoms assessed with a validated psychometric scale, SCL-90, were significantly higher in postmenopausal women (PMW; 60 subjects) than in premenopausal women (20 subjects). In the same PMW, the activity of the dopaminergic system, assessed with the PRL response to the dopamine-blocking agent sulpiride, was significantly lower than that in premenopausal women. During a period...

The synthetic steroid cyproterone acetate (CPA) has been reported to be hepatogenotoxic in female rats depending on sex-specific expression of a hydroxysteroid sulfotransferase (HST) which is involved in the bioactivation of CPA to reactive metabolites. In the present study the ability of CPA to initiate apoptosis in rat hepatocytes in vitro was investigated with respect to sex-specific effects...

PURPOSE In 1992 we initiated a national randomized prospective trial of 3 months of cyproterone acetate before radical prostatectomy compared to prostatectomy alone. Initial results indicated a 50% decrease in the rate of positive surgical margins. This decrease did not translate into a difference in prostate specific antigen (PSA) progression at 3 years. This report is on the long-term outcome...

T cell factor (Tcf) proteins bind beta-catenin and are downstream effectors of Wnt/beta-catenin signals. A recently demonstrated interaction between beta-catenin and the androgen receptor (AR) ligand binding domain has suggested that AR may be a Tcf-independent Wnt/beta-catenin effector. This study demonstrates that there is a direct interaction between the AR DNA binding domain (DBD) and Tcf4....

The current strategy for identifying the carcinogenicity of drugs involves the 2-year bioassay in male and female rats and mice. As this assay is cost-intensive and time-consuming there is a high interest in developing approaches for the screening and prioritization of drug candidates in preclinical safety evaluations. Predictive models based on toxicogenomics investigations after short-term ex...

Abstract Objective To assess the risk of meningioma associated with use high dose cyproterone acetate, a progestogen indicated for clinical hyperandrogenism. Design Observational cohort study. Setting Data from SNDS, French administrative healthcare database, between 2007 and 2015. Participants 253 777 girls women aged 7-70 years living in France who started acetate 2014. had at least one reimb...

We studied thirteen male-to-female (M-->F) and ten female-to-male (F-->M) transsexuals who, for four months, received cross-sex treatment with, respectively, ethinylestradiol and cyproterone acetate, and with testosterone esters. We assessed the effects of treatment on plasma levels of tissue-type plasminogen activator (tPA), von Willebrand factor (vWF), vWF-propeptide (vWF:AgII) and big-endoth...
