Effects of hormone therapy containing 2 mg drospirenone and 1 mg 17β-estradiol on postmenopausal exacerbation of Meniere's disease: Preliminary study. Exp Ther Med 2021; 22:1103. [PMID: 34504557 PMCID: PMC8383771 DOI: 10.3892/etm.2021.10537] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Accepted: 07/06/2021] [Indexed: 12/19/2022] Open
Abstract
The present study aimed to evaluate the effects of 2 mg drospirenone (DRSP) and 1 mg 17β-estradiol (E2) hormone therapy (HT) in combination with rehabilitation therapy for postmenopausal women with Meniere's disease (MD). The combined drug hormone treatment was denoted as DRSP/E2. A total of 65 postmenopausal female patients with MD and severe distress were enrolled in the present prospective study. A total of 31 women comprised the study group (group A), undergoing HT and rehabilitation therapy, whereas 34 women who opted for rehabilitation therapy alone comprised the control group (group B). Vestibular function and distress associated with MD were assessed by stabilometry and the Dizziness Handicap Inventory (DHI) questionnaire, respectively. The data were collected at baseline and during the 3- and 6-month follow-up visits. The areas of the stabilometric ellipses exhibited a higher reduction in group A compared with group B with regard to the baseline values at both follow-up assessments (P<0.001). At baseline, both groups exhibited severe self-perceived discomfort, with similar DHI scores of 72.3±3.7 (group A) and 70.6±3.9 (group B; P=0.07). At the 3-month follow-up, both groups underwent a gradual improvement, which was significantly higher in group A (47.5±3.7) compared with in group B (64.2±3.3; P<0.001). At the 6-month follow-up, the DHI scores were improved in group A (43.4±3.4) compared with in group B (58.5±3.1; P<0.001). Therefore, DRSP/E2 HT was effective in reducing the fluid overload, which is characteristic of MD. The findings of the present study demonstrated that integrated therapy based on the administration of DRSP/E2 HT and rehabilitation may be more effective compared with rehabilitation alone for the management of postmenopausal exacerbation of MD.

Abstract
BACKGROUND Sex hormones are known to have some influence on nasal functions, but their effect on the decongestive response of the nasal mucosa during menstrual cycle is still undetermined. OBJECTIVES The aim of this study was to examine the nasal physiology, the interconnectedness of olfactory and respiratory nasal function and the decongestive response of the nasal mucosa during menstrual cycle. METHODS This study included 101 healthy women aged 23.26 ± 4.81 years with a regular menstrual cycle. The nasal respiratory function and the decongestive response of the nasal mucosa were examined by rhinomanometry. Subjective sense of nasal obstruction and the subjective odor intensity were assessed by standardized questionnaires. The odor identification ability was assessed by Sniffin' Sticks test. RESULTS Statistically significant higher values of nasal resistance (0.311 ± 0.107 Pa/cm3/s) and NOSE score (11.893 ± 13.83) were observed in the ovulatory phase compared to the luteal (0.281 ± 0.084 Pa/cm3/s and 9.029 ± 11.12). An odor identification test score was significantly higher in luteal phase (12.476 ± 1.48) compared to the ovulatory phase (11.971 ± 1.51), opposite of odor intensity. The difference of nasal resistance before and after decongestion was significantly higher in ovulatory phase (0.105 ± 0.097 Pa/cm3/s) compared to the luteal (0.084 ± 0.079 Pa/cm3/s). Correlation between subjective and objective parameters of the examinated nasal functions was not statistically significant in any menstrual phase. CONCLUSION In the population of women studied, total nasal resistance and NOSE score were significantly lower in the luteal phase of the menstrual cycle. Odor identification was significantly higher in the luteal phase but odor intensity significantly higher in the ovulatory phase. The decongestive response of nasal mucosa was better in the ovulatory phase of the menstrual cycle.

Association between subjective olfactory dysfunction and female hormone-related factors in South Korea. Sci Rep 2019; 9:20007. [PMID: 31882785 PMCID: PMC6934502 DOI: 10.1038/s41598-019-56565-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2019] [Accepted: 11/30/2019] [Indexed: 12/27/2022] Open
Abstract
An association between olfactory dysfunction and female hormone level has been reported; however, no previous studies have investigated the correlation with life-long female hormone exposure. The aim of this study was to estimate the association between subjective olfactory dysfunction and various endogenous and exogenous female hormone-related factors including age at menarche and menopause, number of pregnancies and deliveries, age at first and last delivery, duration of breastfeeding, use of oral contraceptives, and use of hormone therapy. The study analysed a total of 3863 female participants using data from the Korean National Health and Nutrition Examination Survey V (2010-2012). The prevalence of olfactory dysfunction was 3.5% for premenopausal participants and 6.2% for postmenopausal women. Among premenopausal women (compared to women breastfed less than 12 months), the 12-24-month group (OR = 4.690, 95% CI = 1.431-15.369) and the 25-48-month group (OR = 6.548, 95% CI = 1.758-24.394) had higher rates of olfactory dysfunction. In postmenopausal women, starting menopause at a younger age was positively associated with olfactory dysfunction (OR = 0.939, 95% CI = 0.887-0.993). These data suggest that a longer duration of endogenous oestrogen deprivation is associated with subjective olfactory dysfunction.

Abstract
OBJECTIVE 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. METHODS 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. RESULTS 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). CONCLUSIONS 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.

Differences in peripheral sensory input to the olfactory bulb between male and female mice. Sci Rep 2017; 7:45851.

Abstract
Female mammals generally have a superior sense of smell than males, but the biological basis of this difference is unknown. Here, we demonstrate sexually dimorphic neural coding of odorants by olfactory sensory neurons (OSNs), primary sensory neurons that physically contact odor molecules in the nose and provide the initial sensory input to the brain’s olfactory bulb. We performed in vivo optical neurophysiology to visualize odorant-evoked OSN synaptic output into olfactory bub glomeruli in unmanipulated (gonad-intact) adult mice from both sexes, and found that in females odorant presentation evoked more rapid OSN signaling over a broader range of OSNs than in males. These spatiotemporal differences enhanced the contrast between the neural representations of chemically related odorants in females compared to males during stimulus presentation. Removing circulating sex hormones makes these signals slower and less discriminable in females, while in males they become faster and more discriminable, suggesting opposite roles for gonadal hormones in influencing male and female olfactory function. These results demonstrate that the famous sex difference in olfactory abilities likely originates in the primary sensory neurons, and suggest that hormonal modulation of the peripheral olfactory system could underlie differences in how males and females experience the olfactory world.

Abstract
Olfactory deficits are observed early in the course of chronic neurological disorders including Alzheimer's disease (AD). Estrogen treatment in post-menopausal women reduced the incidence of olfactory dysfunction, raising the possibility that estrogen treatment can cure olfactory deficits in preclinical stages of AD. In this study, we examined the estradiol׳s effects on neurite outgrowth in explant cultures of mouse olfactory epithelium (OE). We found that neurons in OE cultures treated with 100 pM 17-β estradiol (estradiol) had significantly longer neurite outgrowth than cultures treated with ethanol alone (vehicle). The OE neurons expressed estrogen receptors alpha (ERα) and ER beta (ERβ). Estrogen treatment upregulated both ERα and ERβ expression in OE culture. Treatment of OE cultures with propyl pyrazole triol (PPT), a selective agonist for ERα increased neurite outgrowth to comparable extent as estradiol treatment. In contrast, 2,3-bis-4-hydroxyphenyl (DPN), a specific agonist for ERβ, had no effect on neurite outgrowth. Furthermore, estradiol treatment increased neurite outgrowth in OE cultures derived from ERβ-deficient/knockout mice and wild-type littermates, but not in ERα-deficient/knockout mice. These data suggest that ERα mediates the neurite outgrowth promoting effects of estradiol in OE cultures. We propose that olfactory dysfunction in chronic neurological disorders, where estrogen deficiency is a risk factor, is an indicator of compromised axonal regeneration of olfactory sensory neurons.

Abstract
Progestogens share one common effect: the ability to convert proliferative endometrium to its secretory form. In contrast, their biological activity is varied, depending on the chemical structure, pharmacokinetics, receptor affinity and different potency of action. Progestogens are widely used in the treatment of menstrual cycle disturbances, various gynaecological conditions, contraception and menopausal hormone therapy. The administration of progestogen in menopausal hormone therapy is essential in women with an intact uterus to protect against endometrial hyperplasia and cancer. Progestogen selection should be based on the characteristics available for each progestogen type, relying on the assessment of relative potency of action in experimental models and animal models, and on the indirect knowledge brought by studies of the clinical use of different progestogen formulations. The choice of progestogen should involve the conscious use of knowledge of its benefits, with a focus on minimizing potential side effects. Unfortunately, there are no direct clinical studies comparing the metabolic effects of different progestogens.

Abstract
Olfactory dysfunction can be an early sign of Alzheimer's disease. Since hormone replacement therapy (HRT) may protect against Alzheimer's disease in postmenopausal women, the question arises as to whether it also protects against olfactory dysfunction in such women. A total of three olfactory and 12 neurocognitive tests were administered to 432 healthy postmenopausal women with varied HRT histories. Serum levels of reproductive hormones were obtained for all subjects; APOE-ε4 haplotype was determined for 77 women. National Adult Reading Test and Odor Memory/Discrimination Test scores were positively influenced by HRT. Odor Identification and Odor Memory/Discrimination Test scores were lower for women who scored poorly on a delayed recall test, a surrogate for mild cognitive impairment. The Wechsler Adult Intelligence Scale, Revised, as a Neuropsychological Instrument Spatial Span Backwards Test scores were higher in women receiving estrogen and progestin HRT and directly correlated with serum testosterone levels, the latter implying a positive effect of testosterone on spatial memory. APOE-ε4 was associated with poorer odor threshold test scores. These data suggest that HRT positively influences a limited number of olfactory and cognitive measures during menopause.

Abstract
BACKGROUND Nasal congestion that is not present before pregnancy represents a distinct clinical entity called pregnancy rhinitis. The aim of this study is to evaluate the clinical characteristics of nasal physiology over the course of pregnancy. METHODS The study was conducted with 85 pregnant women and 26 nonpregnant controls. We measured nasal airway patency objectively via acoustic rhinometry (ARM) and anterior rhinomanometry (RMM) and subjectively via the Nasal Obstruction Symptom Evaluation (NOSE) scale in each trimester and compared the results to those of the controls. RESULTS The NOSE scores of control and pregnant women showed no difference (p = 0.866). Minimal cross-sectional area (MCA1; minimal cross sectional area at nasal valve and MCA2; minimal cross sectional area at the level where the head of inferior turbinate is placed) decreased significantly between the first and third trimesters: first trimester 0.37 cm(2), third trimester 0.31 cm(2). There was no difference between each trimester with regard to total nasal resistance. The correlation analysis between the NOSE score and both total volume and MCA1 in all patients showed no significance (r = -0.10, p = 0.318; r = -0.04, p = 0.654, respectively). CONCLUSION Pregnancy affects nasal physiology adversely and impairs nasal breathing in some women. However, based on the findings of this study, we concluded that this clinical entity may not be considered as a disease without complementary symptoms despite the presence of objective changes in nasal parameters.

Abstract
After a worldwide breakdown of hormone therapy [HT] following the publications of the Women's Health Initiative trial and Million Women's Study in 2002-2003, there is now a trend to turn attention again to HT and to explore particular progestogens, which have been discredited with respect to their side effects. The progestogens to be considered should control undue proliferation of the endometrium and should not interfere negatively with the positive effects of estradiol, regarding carbohydrate and lipid metabolism as well as hemostasis. In the present review, three "newer progestogens" are scrutinized regarding their various actions, in combination with estradiol; the progestogens include dienogest, drospirenone and nomegestrol acetate. This article is part of a special issue entitled Menopause.

Abstract
OBJECTIVE To systematically review the literature and appraise the evidence reporting the effects of women's health, including pregnancy, postpartum, menstruation, oral contraception, menopause, and hormone replacement therapy, on common rhinological pathologies and nasal physiology. DATA SOURCES Systematic search strategy using MEDLINE (1966-2012) and EMBASE (1980-2012) databases. REVIEW METHODS Title review, abstract screening, and then full paper analysis were undertaken by 2 authors independently. Level of evidence was graded according to the Oxford Centre of Evidence Based Medicine 2011 criteria and risk of bias assessment using the Jadad scale for randomized controlled trials and Newcastle-Ottawa Scale for cohort and case-controlled studies. RESULTS Over the 46 years analyzed, the search strategy produced 2904 titles. In total, 314 abstracts were screened, from which 192 full-text articles were evaluated, and 145 research papers met all the criteria for inclusion in the study. Overall, the available evidence was of low quality. Seventy percent of studies (102 of 145) were case reports or case series from which only limited conclusions can be drawn. Only 3% of the included papers (4 of 145) were randomized controlled studies. The remaining data were mainly of a prospective cohort design. Study heterogeneity in design and measured outcomes resulted in data synthesis being limited to a descriptive/exploratory review. Study findings are presented by women's health category and then by rhinological manifestation with important clinical correlations highlighted. CONCLUSION Physiological and hormonal changes occurring as a normal part of women's health have an important influence on rhinological function and disease.

Abstract
Although a significant impact of cycle phase on olfactory thresholds has been shown in females, limited data exist regarding discrimination and identification. Therefore, we investigated a broader range of olfactory performance and analyzed the impact of cycle phase and oral contraception. We measured 80 healthy Caucasians, including 20 females taking oral contraceptives and 40 females without oral contraception who were further divided into follicular and luteal phase. Olfactory performance of all participants was assessed twice using the "Sniffin' Sticks" battery and intensity and pleasantness ratings of n-butanol were collected. Data analysis revealed that females outperformed males in odor discrimination and odor identification. In the luteal phase, higher thresholds and higher intensity ratings for n-butanol emerged. Duration of oral contraception correlated positively with olfactory performance pointing to better performance with longer intake. Hence, our data show that odor performance is affected by menstrual cycle phase and duration of oral contraception intake and thus can be modulated by hormonal changes.

Abstract
Olfactory dysfunction often precedes other clinical symptoms in chronic neurodegenerative diseases like Alzheimer's disease and Parkinson's disease. Estrogen deficiency and apoE genotype are known risk factors in these diseases and these factors also affect olfaction. Therefore we examined the effects of estradiol replacement following ovariectomy on expression of apoE and markers of cell proliferation, neuronal maturation, synaptogenesis and reactive gliosis in the primary olfactory pathway of wild-type (WT) and apoE knockout (KO) mice. Estradiol replacement increased apoE staining in the olfactory nerve and glomerular layers. Estradiol increased astrocyte density and olfactory epithelium (OE) thickness regardless of the genotype. In addition estradiol treatment increased the number of mature neurons in the OE and glomerular synaptophysin in both genotypes, but the magnitude of increase was greater in the WT than in the KO mice. These data suggest that estrogen and apoE act synergistically to minimize the loss of mature sensory neurons and synapses following ovariectomy.

Abstract
Background Gender differences, related to varying sexual hormone levels and hormone secretion patterns across the lifespan, contribute to women's vulnerability to mood disorders and major depression. Women are more prone than men to depression, from puberty onwards, with a specific exposure across the menopausal transition. However, controversy still exists in considering fluctuation/loss of estrogen as a specific aetiologic factor contributing to depression in perimenopause and beyond. Aims To briefly review the interaction between changes in menopausal hormone levels, mood disorders, associated neuropsychological co-morbidities and ageing, and to evaluate the currently available therapeutic options for perimenopausal mood disorders: (a) treatment of light to moderate mood disorders with hormonal therapy (HT); (b) treatment of major depression with antidepressants; (c) the synergistic effect between HT and antidepressants in treating menopausal depression. Results Depression across the menopause has a multifactorial aetiology. Predictive factors include: previous depressive episodes such as premenstrual syndrome and/or postpartum depression; co-morbidity with major menopausal symptoms, especially hot flashes, nocturnal sweating, insomnia; menopause not treated with HT; major existential stress; elevated body mass index; low socioeconomic level and ethnicity. Postmenopausal depression is more severe, has a more insidious course, is more resistant to conventional antidepressants in comparison with premenopausal women and has better outcomes when antidepressants are combined with HT. Conclusion The current evidence contributes to a re-reading of the relationship between menopause and depression. The combination of the antidepressant with HT seems to offer the best therapeutic potential in terms of efficacy, rapidity of improvement and consistency of remission in the follow-up.
