estradiol-drospirenone-combination and Cardiovascular-Diseases

Menopause is accompanied by an increased prevalence of hypertension, which may partially explain the corresponding cardiovascular risk observed in postmenopausal women. The relationship between blood pressure and cardiovascular risk is continuous, consistent and independent of other risk factors. There are profound benefits of treating hypertension: antihypertensive therapy has been associated with large reductions in stroke, myocardial infarction and heart failure. Despite these proven benefits, hypertension is inadequately treated, or not treated at all, in the majority of patients. There has been concern regarding the use of hormone therapy in hypertensive postmenopausal women. Drospirenone/17beta-estradiol, a hormone therapy, has been demonstrated to lower blood pressure in hypertensive postmenopausal women either alone or when administered simultaneously with antihypertensive drugs. This might offer a potential advantage in patients with elevated blood pressure. It is also known that the risk for target organ events extends to levels well below the established definition of 140/90 mmHg. High-normal blood pressure carries an increased cardiovascular risk when compared to lower levels of blood pressure. Identification and management of elevated blood pressure are an important component of the successful management of the postmenopausal woman and can help prevent the untoward consequences of elevated blood pressure.

To assess the effects of oral low-dose and non-oral hormone therapy (HT) on ultra-sensitive C-reactive protein (CRP), atrial natriuretic peptide (ANP), and cardiovascular risk factors in postmenopause.. In this randomized, cross-over study, 44 recently postmenopausal women, with no clinical evidence of cardiovascular disease, received oral low-dose HT (estradiol 1 mg + drospirenone 2 mg/day) for 3 months. Forty-two patients received non-oral, conventional HT (1.5 mg/day percutaneous 17β-estradiol gel or equivalent for nasal route) for 3 months followed by 200 mg/day micronized progesterone by the vaginal route (14 days during each menstrual period). After 3 months, patients were crossed over without washout. Post-HT vs. pre-HT measures were determined: lipids, glucose, body mass index, waist circumference, fibrinogen, CRP-stratified levels, and ANP levels. The study was registered at clinical trials.gov (NCT01432028).. The mean age was 51 ± 3 years and the mean time since the menopause was 22 ± 10 months. CRP-stratified high levels decreased in a higher number of non-oral HT patients, who moved to intermediate and low levels (p = 0.02). No effect of HT was observed on ANP levels (baseline 67.4 (18.4-104.5), low-dose oral 43.5 (14.4-95.9), non-oral 39.8 (15.5-67.5) pg/ml). Markers of endothelial function did not worsen with either low-dose oral or non-oral HT: von Willebrand factor (baseline 118 ± 37%, low-dose oral 119 ± 38%, non-oral 108 ± 3%, p < 0.01), fibrinogen (baseline 356 ± 58 mg/dl; low-dose oral 343 ± 77 mg/dl; non-oral 326 ± 71 mg/dl, p < 0.01).. Low-dose oral and non-oral HT for 6 months had neutral or beneficial effects in recently postmenopausal women with no clinical evidence of cardiovascular disease.

To evaluate the effects of a daily E2 (1 mg) plus drospirenone oral formulation (2 mg) on glycoinsulinemic metabolism, lipid profile, and endothelial function in symptomatic healthy menopausal women.. Randomized, double-blind study.. Operative Division of Endocrinological Gynecology, Catholic University of the Sacred Heart, Rome, Italy.. Forty postmenopausal women.. Patients were randomly submitted to receive treatment with an oral dose of E2 (1 mg) plus drospirenone (2 mg) (group A) or placebo (group B).. Hormonal and lipid assessment; evaluation of glucose and insulin metabolism by the clamp test and the oral glucose tolerance test; evaluation of endothelial function by the vascular reactivity test.. Total cholesterol levels, low-density lipoprotein cholesterol levels, and nonesterified fatty acids levels significantly decreased both after 3 and 6 months. No changes in high-density lipoprotein, triglycerides, apolipoprotein A1, apolipoprotein B, and lipoprotein (a) were found. Treatment resulted in few changes in glycoinsulinemic metabolism. We observed a significant reduction of the area under curve of insulin after 6 months of therapy. Endothelial function was significantly influenced by treatment, and an improvement in both flow-mediated dilatation and nitrate-mediated dilatation values after 6 months was observed.. Low-dose E2/drospirenone treatment did not reveal any negative effect on carbohydrate metabolism, acting in a neutral way on insulin sensitivity. The treatment induced favorable changes in lipid profile and showed a significant improvement of vascular reactivity.
