Hypertension in postmenopausal women: how to approach hypertension in menopause.
Modena, MG
High blood pressure & cardiovascular prevention : the official journal of the Italian Society of Hypertension. 2014;(3):201-4
Abstract
During fertile life women are usually normo or hypotensive. Hypertension may appear during pregnancy and this represents a peculiar phenomenon increasing nowadays for delay time of pregnancy. Gestational hypertension appears partially similar to hypertension in the context of metabolic syndrome for a similar condition of increased waste circumference. Parity, for the same pathogenesis, has been reported to be associated to peri and postmenopausal hypertension, not confirmed by our study of parous women with transitional non persistent perimenopausal hypertension. Estrogen's deficiency inducing endothelial dysfunction and increased body mass index are the main cause for hypertension in this phase of life. For these reasons lifestyle modification, diet and endothelial active drugs represent the ideal treatment. Antioxidant agents may have a role in prevention and treatment of hypertension. In conclusion, hypertension in women represents a peculiar constellation of different biological and pathogenic factors, which need a specific gender related approach, independent from the male model.

Abstract
OBJECTIVE Our objective was to compare the effects of oral vs. transdermal estrogen therapy on C-reactive protein (CRP), IL-6, E- and P-selectin, intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule-1, serum amyloid A, transferrin, prealbumin, IGF-I, SHBG, thyroxine-binding globulin (TBG), and cortisol-binding globulin (CBG) in naturally menopausal women. DESIGN This was a randomized, open-label crossover clinical trial. A 6-wk withdrawal from prior hormone therapy (baseline) was followed in randomized order by 12-wk oral conjugated equine estrogens (CEEs) (0.625 mg/d) and 12-wk transdermal estradiol (E2) (0.05 mg/d), with oral micronized progesterone (100 mg/d) given continuously during both regimens. RESULTS A total of 27 women enrolled, and 25 completed both treatment periods. Nine parameters changed significantly during oral CEE (median percent change from baseline; P value): CRP (192%; P <0.001); E-selectin (-16.3%; P = 0.003); P-selectin (-15.3%; P = 0.012); ICAM-1 (-5%; P = 0.015); transferrin (5.3%; P = 0.024); IGF-I (-30.5%; P < 0.001); SHBG (113%; P < 0.001); TBG (38%; P < 0.001); and CBG (20%; P < 0.001). With transdermal E2, only three parameters changed significantly and to a lesser degree: ICAM-1 (-2.1%; P = 0.04); IGF-I (-12.5%; P < 0.001); and SHBG (2.6%; P = 0.042). During oral CEE the intrasubject changes in CRP correlated strongly with the changes in serum amyloid A (r = 0.805; P < 0.001), and were only weakly associated with the changes in SHBG (r = 0.248; nonsignificant), TBG (0.430; P = 0.031), and CBG (r = 0.072; nonsignificant). The log-log relationship between CRP and IL-6 observed at baseline showed a parallel shift during oral CEE, suggesting an amplified hepatic response or a greater sensitivity to IL-6 stimulation. CONCLUSION Compared with oral CEE, transdermal E2 exerts minimal effects on CRP and the other inflammation and hepatic parameters.

A review of drospirenone for safety and tolerability and effects on endometrial safety and lipid parameters contrasted with medroxyprogesterone acetate, levonorgestrel, and micronized progesterone.
Shulman, LP
Journal of women's health (2002). 2006;(5):584-90
Abstract
BACKGROUND Drospirenone, a novel synthetic progestin, possesses characteristics more like natural progesterone than other synthetic progestins, such as medroxyprogesterone acetate and levonorgestrel. The antiandrogenic and antimineralocorticoid properties of drospirenone may, in the context of menopausal management, provide potential novel benefits in its effect on lipids and blood pressure while reducing the occurrence of water retention, acne vulgaris, and hirsutism. METHODS This review compares safety and tolerability data from clinical trials of drospirenone, medroxyprogesterone acetate, levonorgestrel, and micronized progesterone. RESULTS Results suggest that drospirenone possesses a generally well-accepted side effect profile and resembles comparator oral progestogens in conferring endometrial protection with no significant effect on weight. One study indicates that drospirenone may have a benign effect on lipid parameters, having been seen to significantly lower total cholesterol and lowdensity lipoprotein levels while maintaining high-density lipoprotein and triglyceride levels. Drospirenone also differs from the other progestogens in lowering blood pressure levels in hypertensive patients while having a mild blood pressure-lowering effect on nonhypertensive patients. CONCLUSIONS Among pharmacological options for menopause management, drospirenone may provide certain advantages over other progestogens in its effect on risk factors for cardiovascular disease and, thus, constitutes a useful addition to the menopausal armamentarium.

Nappi, RE, Malavasi, B, Brundu, B, Facchinetti, F
Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology. 2005;(1):30-5
Abstract
OBJECTIVE To investigate, in a randomized clinical study, the efficacy of an isopropanolic aqueous extract of Cimicifuga racemosa (CR) on climacteric complaints in comparison with low-dose transdermal estradiol (TTSE2). Hormonal parameters, lipid profile and endometrial thickness were also evaluated. METHODS Sixty-four postmenopausal women were enrolled and over the course of 3 months filled in a diary recording the number of hot flushes per day. Other climacteric symptoms (vasomotor and urogenital symptoms) as well as anxiety and depression, were evaluated at baseline and after 3 months. Gonadotropins (follicle-stimulating hormone (FSH), luetinizing hormone (LH)), prolactin (PRL), 17 beta-estradiol (17beta-E2) and cortisol, lipid profile (total cholesterol high-density lipoprotein (HDL)/low-density lipoprotein (LDL)-cholesterol, triglycerides, liver function (glutamic-oxalacetic transaminase, glutamic-pyruvic transaminase) and endometrial thickness were measured. Patients were randomly allocated to receive, for 3 months, either 40 mg isopropanolic aqueous CR extract daily or 25 microg TTSE2 every 7 days plus dihydrogesterone 10 mg/day for the last 12 days of the 3-month estradiol treatment. RESULTS Both CR and low-dose TTSE2 significantly reduced the number of hot flushes per day (p < 0.001) and vasomotor symptoms (p < 0.001), starting at the first month of treatment. Such a positive effect was maintained throughout the 3 months of observation, without any significant difference between the two treatments. An identical effect was evident also for both anxiety (p < 0.001) and depression (p < 0.001) which were significantly reduced following 3 months of both CR and low-dose TTSE2. Total cholesterol was unchanged by CR treatment but significantly (p < 0.033) reduced by 3 months of low-dose TTSE2. A slight but significant increase of HDL-cholesterol (p < 0.04) was found only in women treated with CR, while LDL-cholesterol levels were significantly lowered by 3 months of both CR (p < 0.003) and low dose TTSE2 (p < 0.002). Triglycerides were not affected by both treatments, nor was liver function. FSH, LH and cortisol were not significantly affected after the 3-month treatment, while PRL (p < 0.005) and 17 beta-E2 (p < 0.001) were increased slightly only by low-dose TTSE2. Endometrial thickness was not affected by either CR or low-dose TTSE2. CONCLUSIONS CR (40 mg/day) may be a valid alternative to low-dose TTSE2 in the management of climacteric complaints in those women who cannot be treated with or just refuse conventional strategies.

Tice, JA, Ettinger, B, Ensrud, K, Wallace, R, Blackwell, T, Cummings, SR
JAMA. 2003;(2):207-14
Abstract
CONTEXT Clinical trials demonstrating increased risk of cardiovascular disease and breast cancer among women randomized to hormone replacement therapy have increased interest in other therapies for menopausal symptoms. Dietary supplements containing isoflavones are widely used as alternatives to hormonal therapies for hot flashes, but there is a paucity of data supporting their efficacy. OBJECTIVE To compare the efficacy and safety of 2 dietary supplements derived from red clover with placebo in symptomatic menopausal women. DESIGN, SETTING, AND PARTICIPANTS Randomized, double-blind, placebo-controlled trial of menopausal women, aged 45 to 60 years, who were experiencing at least 35 hot flashes per week. The study was conducted between November 1999 and March 2001 at 3 US medical centers and included women who were recently postmenopausal (mean [SD], 3.3 [4.5] years since menopause) experiencing 8.1 hot flashes per day. Women were excluded if they were vegetarians, consumed soy products more than once per week, or took medications affecting isoflavone absorption. INTERVENTION After a 2-week placebo run-in, 252 participants were randomly assigned to Promensil (82 mg of total isoflavones per day), Rimostil (57 mg of total isoflavones per day), or an identical placebo, and followed-up for 12 weeks. MAIN OUTCOME MEASURE The primary outcome measure was the change in frequency of hot flashes measured by participant daily diaries. Secondary outcome measures included changes in quality of life and adverse events. RESULTS Of 252 participants, 246 (98%) completed the 12-week protocol. The reductions in mean daily hot flash count at 12 weeks were similar for the Promensil (5.1), Rimostil (5.4), and placebo (5.0) groups. In comparison with the placebo group, participants in the Promensil group (41%; 95% confidence interval [CI], 29%-51%; P =.03), but not in the Rimostil group (34%; 95% CI, 22%-46%; P =.74) reduced hot flashes more rapidly. Quality-of-life improvements and adverse events were comparable in the 3 groups. CONCLUSION Although the study provides some evidence for a biological effect of Promensil, neither supplement had a clinically important effect on hot flashes or other symptoms of menopause.

Maturitas. 2001;(1):85-94
Abstract
OBJECTIVE The efficacy and safety of chlormadinone acetate (CA) versus micronized progesterone (P) were assessed in non-hysterectomized postmenopausal women. MATERIALS AND METHODS This was a multicenter, randomized, parallel group study with a 6-month double-blind period followed by a 12-month open period. Patients were randomized to receive every month during 18 months percutaneous 17 beta-estradiol (E(2)) 1.5 mg/day from Day 1 to 24 of treatment cycle, combined from Day 11 to 24 to either CA 10 mg/day (n=167) or P 200 mg/day (n=169). Endometrial biopsy (EB, main analysis criterion) was performed at baseline, and at Day 18-24 of the 6th and 18th cycles. RESULTS At Month 6, EB did not evidence any hyperplasia. EB were inadequate for assessment in 24.5% and 47.5% of patients in the CA and MP groups, respectively. CA was found to be as protective as P (96.3% and 92.0% of success). However, the hormonal status of the endometrium differed (P<0.001): a secretory endometrium was found in 81.5% of the CA patients, compared to 50.7% in the P group. These transformations resulted in predictable, cyclic bleeding in 94.5% of the CA patients, compared to only 62.3% of the P patients (P=0.0001). Unscheduled bleeding, spotting and/or metrorrhagia, were more frequent under P than under CA (17.9% and 13.7%, respectively). The beneficial effects on hot flushes were more important in the CA group than in the P (P<0.001). At Month 18, the biopsy and clinical results were similar to those obtained at Month 6. The safety profile, particularly the lipid one, was similar in both groups, except for drowsiness and dizziness, which were significantly more frequent under P than under CA. CONCLUSION The progestative effects of CA on the endometrium and on menopause-related symptoms were at least as good as those of P. Moreover, CA resulted more often than P in secretory effects, and in satisfying bleeding patterns.

Human reproduction (Oxford, England). 2000;(5):1028-36
Abstract
To assess the safety and efficacy of oestriol in relieving post-menopausal symptoms 53 post-menopausal Japanese women with climacteric symptoms, 27 with natural menopause (group I) and 26 with surgically induced menopause (group II), received oral oestriol, 2 mg daily for 12 months. Clinical parameters including Kupperman index (KI) and the degree of satisfaction with symptomatic relief; serum concentrations of oestradiol, FSH and LH; serum lipids; blood pressure; bone mineral density, serum calcium (Ca), alkaline phosphatase (ALP), and urinary Ca were compared between the two groups. Oestriol improved KI in groups I and II by 49 and 80% respectively. Satisfaction with treatment was 85% in group I and 93% in group II. For both parameters, values were significantly different between groups I and II (P < 0.05 for both). Serum concentrations of oestradiol, FSH and LH changed in group I versus group II 6 months after initiation. A significant decrease in serum ALP and Ca/Cr was observed in group I at 6 months. Except for serum triglycerides, oestriol had no significant effect on lipids. Systolic and diastolic blood pressures were significantly decreased in group I at 3 months versus baseline. Slight vaginal bleeding occurred in 14.3% of group I. Histological evaluation of the endometrium in all women of group I and ultrasound assessment of the breasts following 12 months of oestriol treatment found normal results in all women. Therefore, oestriol appeared to be safe and effective in relieving symptoms of menopausal women. The beneficial biochemical effects of oestriol were marked in the natural menopause. Overall, oestriol may serve as a good choice for hormone replacement therapy to protect against other climacteric symptoms in post-menopausal women who do not need medication for osteoporosis or coronary artery disease.
