phytoestrogens and Vaginal-Diseases

Between 40% and 50% of women in Western countries use complementary therapies to manage menopausal symptoms.. To determine the association of plant-based therapies with menopausal symptoms, including hot flashes, night sweats, and vaginal dryness.. The electronic databases Ovid MEDLINE, EMBASE, and Cochrane Central were systematically searched to identify eligible studies published before March 27, 2016. Reference lists of the included studies were searched for further identification of relevant studies.. Randomized clinical trials that assessed plant-based therapies and the presence of hot flashes, night sweats, and vaginal dryness.. Data were extracted by 2 independent reviewers using a predesigned data collection form.. Hot flashes, night sweats, and vaginal dryness.. In total, 62 studies were identified, including 6653 individual women. Use of phytoestrogens was associated with a decrease in the number of daily hot flashes (pooled mean difference of changes, -1.31 [95% CI, -2.02 to -0.61]) and vaginal dryness score (pooled mean difference of changes, -0.31 [95% CI, -0.52 to -0.10]) between the treatment groups but not in the number of night sweats (pooled mean difference of changes, -2.14 [95% CI, -5.57 to 1.29]). Individual phytoestrogen interventions such as dietary and supplemental soy isoflavones were associated with improvement in daily hot flashes (pooled mean difference of changes, -0.79 [-1.35 to -0.23]) and vaginal dryness score (pooled mean difference of changes, -0.26 [-0.48 to -0.04]). Several herbal remedies, but not Chinese medicinal herbs, were associated with an overall decrease in the frequency of vasomotor symptoms. There was substantial heterogeneity in quality across the available studies, and 46 (74%) of the included randomized clinical trials demonstrated a high risk of bias within 3 or more areas of study quality.. This meta-analysis of clinical trials suggests that composite and specific phytoestrogen supplementations were associated with modest reductions in the frequency of hot flashes and vaginal dryness but no significant reduction in night sweats. However, because of general suboptimal quality and the heterogeneous nature of the current evidence, further rigorous studies are needed to determine the association of plant-based and natural therapies with menopausal health.

The aim of the study was to evaluate the effects of nutraceuticals containing equol on vaginal health of postmenopausal women with vulvovaginal symptoms and dyspareunia.. One hundred twenty-six natural postmenopausal women on +1b +1c (2 and 3-6 y after the final menstrual period, respectively) of the Stages of Reproductive Aging Workshop were enrolled in a nonrandomized trial. Of these, 72 women accepted to use nutraceutical (group A). The remaining 54 women refused the treatment and participated as the control group (group B). Group A was prescribed one tablet daily to take orally, for 8 months. All assessments were made at baseline and at 4 and 8 months. Determination of vaginal maturation index (VMI), evaluation of vaginal pH, and assessment of vaginal atrophy symptoms by the vaginal health index (VHI) were carried out. Dyspareunia score was also measured.. Group A had a significant increase in VMI (68 ± 5 vs 58 ± 8) and improvement of vaginal pH (4.1 ± 1.3 vs 5.1 ± 1.7) compared with baseline, mainly after 8 months of treatment (P < 0.001). Group A had an improvement of VHI after 4 (13 ± 3, P < 0.01) and 8 (16 ± 2, P < 0.001) months of nutraceutical intake. Dyspareunia reduced after 8 months (5.1 ± 1.3 vs 3.8 ± 1.2, P < 0.001) but not after 4 months (4.7 ± 1.1, P = 0.06) of treatment. Group B showed no changes from baseline evaluation (P = 0.22).. Nutraceuticals containing equol could be effective in modulating postmenopausal symptoms, particularly vaginal symptoms, and could be well accepted by the women who usually do not wish to use hormone therapy or cannot use it for medical reasons.

To compare the effects of a 12-week treatment with Pueraria mirifica (PM) gel or a conjugated estrogen cream on vaginal maturation index, vaginal symptom score, vaginal health assessment score, and vaginal flora in postmenopausal women.. In a prospective, noninferiority, randomized controlled study, 82 postmenopausal women with at least one vulvovaginal symptom, that is, dryness, soreness, irritation, dyspareunia, or discharge, were recruited. Participants were randomly assigned into two groups for treatment with either PM gel or conjugated estrogen cream (CEE). The treatment regimen consisted of application of 0.5 g of product intravaginally daily for 2 weeks, and then decreased to three times per week for 10 weeks. Vaginal maturation index, vaginal symptoms score, and vaginal health assessment score were evaluated before the beginning of the study and at 6 weeks and 12 weeks after treatment with PM or CEE.. The vaginal maturation index increased significantly in both treatment groups at week 12, from 22.44 ± 22.28 to 47.56 ± 29.00 and from 27.07 ± 26.12 to 66.90 ± 22.42 in the PM and the CEE groups, respectively (P < 0.05). A significantly higher effect was, however, observed in the CEE group (P < 0.05). Vaginal symptom scores decreased significantly after treatment in both groups, from 4.37 ± 2.79 to 0.95 ± 1.88 and from 4.15 ± 2.16 to 0.68 ± 1.64 in the PM and the CEE groups, respectively (P < 0.05), with no statistically significant different between the two groups (P > 0.05).. The use of a 12-week treatment regimen with Pueraria mirifica gel was shown to be efficacious and safe for the treatment of vulvovaginal atrophy. Conjugated estrogen cream was found to be more effective compared to Pueraria mirifica gel in improving signs of vaginal atrophy and restoring vaginal epithelium at 6 and 12 weeks.

The estrogenic efficacy of topical vaginal application of Pueraria mirifica extract (PM) on the restoration of vaginal atrophy, and the presence of any systemic side effects, were investigated in postmenopausal cynomolgus macaques. Twelve postmenopausal cynomolgus macaques, with complete cessation of menstruation for at least 5 years before start of this experiment, were divided into three groups. They received a topical vaginal application daily of 0.1 or 1% (w/w) PM cream or a conjugated equine estrogen (CEE) cream (a mixture of estrone, equilin, 17β-dihydroequilin, 17α-estradiol and 17α-dihydroequilin at 0.625 mg total estrogen/g cream) for 28 days. Estrogenic efficacy was assessed weekly by vaginal cytology assay and vaginal pH measurement, whilst the plasma luteinizing hormone (LH) and sex skin coloration levels were determined at the end of each treatment period to evaluate the systemic side effects. PM significantly increased the proportion of superficial cells in a dose-dependent manner, with a similar efficacy between 1% (w/w) PM and CEE. Together with increased vaginal maturation, PM decreased the vaginal pH to acidic levels, as observed in the CEE group. PM induced no detected systemic side effects, whilst CEE decreased the plasma LH level and increased the reddish color of the sex skin during the posttreatment period. Topical vaginal treatment with PM stimulated the maturation of the vaginal epithelium without causing systemic side effects in postmenopausal monkeys. The implication is that PM could be a safer alternative to treat vaginal atrophy in postmenopausal women.

Evaluate the effects of vaginal administration of isoflavones derived from Glycine max (L.) Merr. as a treatment option for vaginal atrophy, on the morphology and expression of estrogen receptors in vaginal epithelium of postmenopausal women.. The double-blind, randomized, placebo-controlled, clinical trial. Sixty women were treated for 12 weeks with isoflavone vaginal gel 4% (1g/day) and a placebo gel. After 4 and 12 weeks, the vaginal atrophy symptoms were classified at none, mild, moderate and severe and the vaginal cytology were taken to determine the maturation value. Vaginal pH was measured at the beginning and end of therapy. Microbiopsies in vaginal fornix were performed before the treatment and after 12 weeks of treatment.. Isoflavone vaginal gel was effective for relief of vaginal dryness and dyspareunia symptons and an increase in the intermediate and superficial cells was noted. The vaginal pH in the isoflavone group was 7.1 at baseline and 5.4 after 12 weeks, whereas in the placebo group there was no significant change. A significant increase in thickness after treatment was detected in the Isoflavone Group. The percentage of estrogen receptor positive cells in vaginal epithelium for the Isoflavone Group ranged from 58.5% at the beginning of treatment to 82.6% after 12 weeks. These results were superior to placebo gel.. Glycine max (L.) Merr. at 4% vaginal gel on a daily basis in postmenopausal women led to improvements in vaginal atrophy symptoms, maturation values, vaginal pH, morphology and expression of estrogen receptors in vaginal epithelium. Isoflavones proved good treatment options for relief of vulvovaginal atrophy.

Menopause is often associated with vaginal atrophy and related symptoms, such as vaginal dryness, burning, itching, and dyspareunia, decrease in libido and in general a decrease in the quality of life. The common treatment up to the 1990's has been the oral hormone replacement therapy (HRT), but this treatment has been consequently re-considered due to its adverse effects. Topical estrogenic products have been subsequently developed to minimize the systemic adverse effects of the oral HRT, but they are still considered at risk in case of prolonged use. As an alternative, two clinical trials were performed to investigate the effects of a medical device in the form of a gel, containing hyaluronic acid, liposomes, phytoestrogens from Humulus lupulus extract, and Vitamin E, with the aim of testing its safety and efficacy in post-menopausal women with urogenital atrophy. The first pilot study confirmed in 10 women the good safety profile, both locally and systemically, of the device applied on the external genitals at the dose of 1-2 g/day for 30 days. The second study was carried out, according to a multicenter, open, non-controlled design, in 100 post-menopausal women assigned to the vaginal application of 2.5 g of gel/day for 1 week followed by two applications/week for 11 weeks. The primary end-point was the evaluation of vaginal dryness assessed by a Visual Analogue Scale both by the investigator and the subject. Secondary endpoints were the evaluation of all other symptoms and signs associated with atrophic vaginitis (itching, burning, dyspareunia, vaginal inflammation/oedema and rash assessed by a 4-point scale and presence of vaginal abrasions and disepithelialisation), and the recording of adverse events during the study. At the end of the treatment, an overall judgment on the efficacy and safety of the device was made by the investigator and a judgment on the acceptability of the treatment was made by the subjects. The results showed a marked effect of the tested product on the vaginal dryness and on all other symptoms and signs with statistically significant reductions since the first week of treatment. No treatment-related adverse events were complained by the subjects and the treatment course showed a high level of acceptability by the subjects. This device could be considered an effective and safe alternative treatment of genital atrophy in post-menopausal women, especially when HRT is not recommended.

A traditional asiatic phytoestrogen-rich diet is associated with a lower incidence of estrogen-dependent cancers and clinical consequences of postmenopausal estrogen deficiency. First Wilcox in 1990, showed an increase of the vaginal cell maturation with phytoestrogens on postmenopausal women, but this has not been confirmed in some subsequent studies.. In this study, we analyzed the effects of a 6-month soy-rich diet on the vaginal epithelium of asymptomatic postmenopausal women in a randomized clinical trial. 187 women were recruited for the study and divided into three groups: a phytoestrogen rich diet group; a hormonal replacement group, and a control group. A vaginal sample for hormonal cytology was taken before and at the end of the study, and sent unnamed to a cytologist.. The karyopycnotic index (KI) increased significantly in the diet group and in the HRT group but not in the control group. The maturation value (MV) had an identical trend to the KI.. We conclude that a soy rich diet is efficacious in increasing the maturation indices of vaginal cells. This effect could be a useful marker of the efficacy of a dietary intervention with phytoestrogen rich foods, and should be considered during preventive interventions against menopausal effects and vaginal atrophy.

To analyze the impact of soy protein dietary supplements containing phytoestrogens on menopausal symptoms in healthy postmenopausal women.. A double-blind, placebo-controlled trial was conducted in 94 healthy postmenopausal women aged 50-75 years, with 44 randomized to soy supplements containing 118 mg of isoflavones (daidzein, genistein, glycitein and their respective glycosides), and 50 to an identically presented casein placebo. A validated questionnaire on menopausal symptoms was administered at baseline and at 3 months of treatment. Compliance was assessed by high-performance liquid chromatography assay of urinary phytoestrogens. Statistical analysis was completed using non-parametric statistical methods and multivariate analysis.. At baseline 80% of women recruited were experiencing menopausal symptoms, although symptom severity was mild. Those consuming phytoestrogen supplements had 13- and 17-fold increases in urinary excretion of genistein and daidzein, respectively, with no change in the placebo group. Active soy supplements did not significantly alter either individual symptoms or specific symptom category scores when compared to placebo. Within-group comparisons revealed that the active group reported a significant improvement in vaginal dryness (p = 0.01), libido (p = 0.009), facial hair (p = 0.04) and dry skin (p = 0.027). However, similarly, those on placebo reported an improvement in libido (p = 0.015), facial hair (p = 0.014) and dry skin (p = 0.011) but not vaginal dryness.. In this group of 94 older postmenopausal women with a high frequency of mild menopausal symptoms, 3 months of soy supplements containing phytoestrogens did not provide symptomatic relief compared with placebo.
