Effect Of Menopausal Hormone Therapy Research Articles

From being alive to living a good life: development and outlook of menopause management

<p indent=0mm>Along with rapid economic development and aged tendency of populations, women should not only pursue the extension of life span, but also enjoy a healthy life in the postmenopausal and elder stage. It is imperative to conduct menopause management amongst the menopausal women. Healthy lifestyle is the primary content of menopause management. The effectiveness of menopausal hormone therapy (MHT) is well established, but risks associated with MHT remain complex issues. This article reviews the development and current status of menopause management, summarizes the controversial issues about MHT, and provides an outlook for future research of menopause management.

The beneficial effects of menopausal hormone therapy on renal survival in postmenopausal Korean women from a nationwide health survey

Several studies have demonstrated the nephroprotective effects of estrogen on renal damage. In light of the inconsistent results of previous findings, this study aims to evaluate the in-depth role of menopausal hormone therapy (MHT) on the development of end stage renal disease (ESRD). 3,109,506 Korean adult women who had undergone a medical examination in 2009 (index year) were initially identified for inclusion in this study. We excluded subjects had not experienced menopause naturally, had data missing for at least one variable, and were diagnosed with ESRD within 1 year from the index year. MHT data was obtained from self-reporting questionnaires and the primary outcome was the development of ESRD from the index year until December 31, 2018. A final total of 1,460,311 subjects were included in this study. The participants were divided into four groups according to the duration of MHT; no history of MHT, MHT < 2 years, 2 ≤ MHT < 5 years, MHT ≥ 5 years. During the 9-year study period, a total of 4905 participants developed ESRD. The participants who had a history of MHT use were found to have a 30% reduced risk of developing ESRD. Results from the subgroup analyses were similar to that of the primary study. The findings in this study demonstrate the beneficial effects of MHT on the development of ESRD in postmenopausal women. Based on results, our study may offer suggestions for further studies to investigate the therapeutic options on kidney disease.

Survey-based evaluation of the awareness of pharmaceutical specialists on the pharmacotherapy of climacteric syndrome

Objective: to evaluate the awareness of pharmaceutical specialists on the pharmacotherapy of climacteric syndrome based on survey results.Material and methods. The authors analyzed 394 surveys of pharmaceutical specialists in Saint-Petersburg. The survey consisted of 13 questions, covered the personal characteristics of the participants (age, education, professional experience) and their knowledge about special medicines and food supplements to control climacteric symptoms, indications, and contraindications.Results. The results showed that pharmaceutical specialists saw the difference between combined oral contraceptives and menopausal hormone therapy, but they do not know about the protective cardiovascular effects of menopausal hormone therapy. Most specialists consider menopausal hormone therapy more effective than phytoestrogens, but they have no idea how it works. For most of them, there is hardly any difference between various classes of phytoestrogens. In their opinion, medical representatives and scientific conferences are the main providers of medical information.Conclusion. The analysis of the level of awareness of pharmaceutical specialists about the pharmacotherapy of menopausal syndrome based on the results of the survey revealed insufficient knowledge among pharmacy workers on a number of fundamental issues. Therefore, it is necessary to develop methodological recommendations on menopausal hormone therapy preparations and phytoestrogens-based drugs for pharmaceutical specialists who act as an important intermediate between a doctor and a patient.

Effects of menopausal hormone therapy on erythrocyte n–3 and n–6 PUFA concentrations in the Women’s Health Initiative randomized trial

The factors other than dietary intake that determine tissue concentrations of EPA and DHA remain obscure. Prior studies suggested that, in women, endogenous estrogen may accelerate synthesis of DHA from ɑ-linolenic acid (ALA), but the effects of exogenous estrogen on RBC n-3 (ɷ-3) PUFA concentrations are unknown. We tested the hypothesis that menopausal hormone therapy (HT) would increase RBC n-3 PUFA concentrations. Postmenopausal women (ages 50-79 y) were assigned to HT or placebo in the Women's Health Initiative (WHI) randomized trial. The present analyses included a subset of 1170 women (ages 65-79 y) who had RBC PUFA concentrations measured at baseline and at 1 y as participants in the WHI Memory Study. HT included conjugated equine estrogens (E) alone for women without a uterus (n=560) and E plus medroxyprogesterone acetate (P) for those with an intact uterus (n=610). RBC n-3 and n-6 (ɷ-6) PUFAs were quantified. Effects of E alone and E+P on PUFA profiles were similar and were thus combined in the analyses. Relative to the changes in the placebo group after 1 y of HT, docosapentaenoic acid (DPA; n-3) concentrations decreased by 10% (95% CI: 7.3%, 12.5%), whereas DHA increased by 11% (95% CI: 7.4%, 13.9%) in the HT group. Like DHA, DPA n-6 increased by 13% from baseline (95% CI: 10.0%, 20.3%), whereas linoleic acid decreased by 2.0% (95% CI: 1.0%, 4.1%; P values at least <0.01 for all). EPA and arachidonic acid concentrations were unchanged. HT increased RBC concentrations of the terminal n-3 and n-6 PUFAs (DHA and DPA n-6). These findings are consistent with an estrogen-induced increase in DHA and DPA n-6 synthesis, which is consistent with an upregulation of fatty acid elongases and/or desaturases in the PUFA synthetic pathway. The clinical implications of these changes require further study. The Women's Health Initiative Memory Study is registered at clinicaltrials.gov as NCT00685009. Note that the data presented here were not planned as part of the original trial, and therefore are to be considered exploratory.

Impact of menopausal hormone therapy on colorectal cancer risk-A systematic review.

Colorectal cancer (CRC) is the second most frequently diagnosed cancer in females worldwide. Menopausal hormone therapy (MHT) has been proposed as a potential protective factor for the development of CRC. Yet, the available evidence is controversial. Thus, we aimed at summarizing the current evidence on the effect of MHT on CRC through a systematic review. A systematic literature search identified 1001 potentially relevant articles, out of which 57 original studies and nine meta-analyses were deemed eligible for the final synthesis. The evidence synthesis showed the following: (1) MHT showed a heterogeneity in findings for CRC risk with a slight tendency to a neutral or protective effect; (2) MHT effect was either neutral or protective on colorectal adenoma; (3) MHT had no impact on tumour grade, subsite and histologic types; (4) MHT was not associated with CRC mortality; and (5) MHT showed heterogeneous effects on CRC stage and invasiveness, respectively. In summary, despite some evidence pointing towards a protective effect of MHT on CRC, MHT is currently not recommended for primary CRC prevention by international guidelines due to several important, potentially harmful effects.

Sexual behaviors and function during menopausal transition-does menopausal hormonal therapy play a role?

The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an "end all" in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors. A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls-MHT non-users (n = 103). Diagnostic and Statistical Manual of Mental Disorders -five criteria were used to assess sexual dysfunction. Sexual problems were evaluated by the Changes in Sexual Function Questionnaire (CSFQ), body image by Body Exposure during Sexual Activity Questionnaire, and quality of relationship by the Well-Match Relationship Questionnaire. Logistic regression was used to determine the risk factors for FSD and sexual problems. Women using MHT had higher body esteem during sexual activities, better sexual function (CSFQ) in all domains except desire/interest, better quality of relationship, and lower prevalence of FSD and sexual complaints (CSFQ) except arousal/excitement problems. However, self-rated effects of MHT on sexual behaviors showed that MHT did not play a major role. Women with secondary and higher education (OR = 0.09, CI: 0.02-0.4; P < 0.01 and OR = 0.2, CI: 0.05-1.0; P < 0.05, respectively) and with a higher number of lifetime sexual partners (OR = 0.6, CI: 0.4-0.9; P < 0.01) were less likely to have FSD. In contrast, individuals with more anxious behaviors during sexual activity (OR = 3.2, CI: 1.3-7.3; P < 0.01) and with more severe menopausal symptoms (OR = 1.1, CI: 1.0-1.2; P < 0.001) were more likely to have FSD. Using MHT was not associated with that risk nor with sexual function. In women during menopausal transition, sexual behaviors were different in MHT users compared with non-users. However, in this cross-sectional observational study conducted in 210 women between the ages of 45 to 55 years, using MHT was not associated with modification of sexual function, decreasing the risk of sexual dysfunction, nor sexual problems.

A systematic review and meta-analysis of effects of menopausal hormone therapy on cardiovascular diseases

A systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies was conducted to assess the association between menopausal hormone therapy and cardiovascular disease. The PubMed and EMBASE databases were searched for articles published from 2000 to 2019, using review methods based on a previous Cochrane review. Quality assessment of RCTs and observational studies was conducted using the Jadad scale and the Newcastle–Ottawa Scale, respectively. A total of 26 RCTs and 47 observational studies were identified. The study populations in the RCTs were older and had more underlying diseases than those in the observational studies. Increased risks of venous thromboembolism [summary estimate (SE), 95% confidence interval (CI): RCTs, 1.70, 1.33–2.16; observational studies, 1.32, 1.13–1.54] were consistently identified in both study types, whereas an increased risk of stroke in RCTs (SE: 1.14, 95% CI: 1.04–1.25) and a decreased risk of myocardial infarction in observational studies (SE: 0.79, 95% CI: 0.75–0.84) were observed. Differential clinical effects depending on timing of initiation, underlying disease, regimen type, and route of administration were identified through subgroup analyses. These findings suggest that underlying disease and timing of initiation should be carefully considered before starting therapy in postmenopausal women.

Effect of Menopausal Hormone Therapy on the Vaginal Microbiota and Genitourinary Syndrome of Menopause in Chinese Menopausal Women.

Genitourinary syndrome of menopause (GSM) is a chronic and progressive condition with a series of vulvovaginal, sexual, and lower urinary tract discomforts, mainly due to hypoestrogenism. Menopausal hormone therapy (MHT) has generally been considered as the most effective treatment for GSM. In addition, vaginal microbiota is of particular significance to gynecological and reproductive illnesses and potentially has some intimate connections with GSM. Consequently, we sought to evaluate how MHT impacts the composition and structure of vaginal microbiota while alleviating GSM in Chinese menopausal women aged 45–65 years, which has not been investigated previously. 16S rRNA gene sequencing was performed to analyze microbial diversity and composition using vaginal swabs obtained from 100 menopausal women, classified as MHT women who have been taking tibolone regularly (n = 50) and non-treated women who never received any treatment (n = 50). Vaginal Health Index Score (VHIS) and GSM symptoms inquiry were also performed. We found that the vaginal microbial diversity decreased and that the abundance of Lactobacillus increased to be the dominant proportion significantly in the MHT group, in considerable contrast to vaginal microbiota of the non-treated group, which significantly comprised several anaerobic bacteria, namely, Gardnerella, Prevotella, Escherichia-Shigella, Streptococcus, Atopobium, Aerococcus, Anaerotruncus, and Anaerococcus. In this study, women without any MHT had significantly more severe GSM symptoms than those receiving tibolone, especially with regard to vulvovaginal dryness and burning, as well as decreased libido (P < 0.01). However, there was no significant difference in the severity of urological symptoms between the groups (P > 0.05). Furthermore, Lactobacillus was demonstrated to be associated with VHIS positively (r = 0.626, P < 0.001) and with GSM negatively (r = −0.347, P < 0.001). We also identified Chlamydia (r = 0.277, P < 0.01) and Streptococcus (r = 0.270, P < 0.01) as having a prominent association with more serious GSM symptoms. Our study provided an elucidation that MHT could notably alleviate GSM and conspicuously reshape the composition of the vaginal microbiota, which is of extreme importance to clinical practice for the management of GSM.

Effect of menopausal hormone therapy on proteins associated with senescence and inflammation.

BackgroundEstrogen may inhibit cell senescence that contributes to age‐related disorders.This study determined the effects of menopausal hormone treatments on circulating levels of markers of cell senescence.MethodsGrowth differentiation factor 15 (GDF15), tumor necrosis factor receptor 1 (TNFR1), FAS, and macrophage inflammatory protein 1α (MIP1α) were measured in serum using multiplexed bead‐based assays and compared among menopausal women participating in the Kronos Early Estrogen Prevention Study randomized to either placebo (n = 38), oral conjugated equine estrogen (oCEE, n = 37), or transdermal 17β‐estradiol (tE2, n = 34). Serum levels of the senescent markers for each treatment were compared to placebo 36 months after randomization using the Wilcoxon rank sum test.ResultsSerum levels of GDF15, TNFR1, and FAS, but not MIP1α, were lower in both the oCEE and tE2 groups compared to placebo. The difference in levels between treatment and placebo for GDF15, TNFR1, and FAS were greater for oCEE [−108 pg/mL (p = .008), −234 pg/mL (p = .0006), and −1374 pg/mL (p < .0001), respectively] than for tE2 [−76 pg/mL (p = .072), −105 pg/mL (p = .076), and −695 pg/mL (p = .036), respectively]. Additionally, TNFR1 showed a positive association with time past menopause (correlation = 0.255, p = .019).ConclusionsCirculating levels of some markers of cell senescence were lower in menopausal women treated with oCEE and tE2 compared to placebo. Differences in the magnitude of effect of the two active treatments may reflect the differences in circulating levels of estrogen metabolites due to formulation and mode of delivery. These data generate new hypotheses with regard to the effects of menopause on the biology of aging.

A randomized trial on the effect of oral combined estradiol and drospirenone on glucose and insulin metabolism in healthy menopausal women with a normal oral glucose tolerance test

BackgroundMenopause is often associated with a central accumulation of body fat. This provokes insulin resistance. The resulting hyperinsulinemia may increase the risk of diabetes, cardiovascular disease and breast cancer. Long-term studies indicate that menopausal hormone therapy (MHT) reduces insulin resistance. To broaden knowledge of the mechanisms behind the influence of MHT on glucose homeostasis we focused on the direct short-term effects of MHT with oral combined estradiol and drospirenone on glucose and insulin metabolism in healthy postmenopausal women. MethodsThis randomized, placebo-controlled study recruited 80 healthy postmenopausal women. Women were randomized to treatment with estradiol 1 mg continuously combined with drospirenone 2 mg or placebo for 6–8 weeks. All participants underwent an oral glucose tolerance test (OGTT) before and after the treatment period. Glucose, insulin, fructosamine and C-peptide levels were measured in serum before and 30, 60, 90, 120 and 150 min after a 75-gram oral glucose challenge. ResultsAfter intervention, significantly higher glucose levels at 120 min (p < 0.024) and 150 min (p < 0.030) were observed in the MHT group compared with the placebo group. These glucose levels remained within the normal range.A significantly lower insulin peak serum level (p < 0.040) and a non-significantly smaller area under the curve (AUC) for insulin levels (p = 0.192) was observed in the MHT group at the end of the study period relative to baseline. No significant change in the insulin AUC in the placebo group was observed. There were no significant differences in fructosamine, HOMA-IR and C-peptide levels between the MHT group and the placebo group. ConclusionThis double-blind randomized study (EC/2008/694) indicates that treating healthy, postmenopausal women with 1 mg estradiol continuously combined with 2 mg drospirenone significantly decreases peak insulin levels and increases peak glucose levels during an OGTT compared to placebo. These glucose levels remained within the normal range.

Menopausal Hormone Therapy and Cardiovascular Risk: Where are we Now?

Transition to menopause is associated with an increase in cardiovascular disease (CVD) risk, mainly attributed to lipid and glucose metabolism dysregulation, as well as to body fat redistribution, leading to abdominal obesity. Indeed, epidemiological evidence suggests that both early menopause (EM, defined as age at menopause <45 years) and premature ovarian insufficiency (POI, defined as age at menopause <40 years) are associated with 1.5-2-fold increase in CVD risk. Menopausal hormone therapy (MHT) exerts a favorable effect on CVD risk factors (with subtle differences regarding oestrogen dose, route of administration, monotherapy or combination with progestogen and type of progestogen). Concerning CVD morbidity and mortality, most studies have shown a beneficial effect of MHT in women at early menopausal age (<10 years since the final menstrual period) or younger than 60 years. MHT is strongly recommended in women with EM and POI, as these women, if left untreated, are at risk of CVD, osteoporosis, dementia, depression and premature death. MHT has also a favorable benefit/ risk profile in perimenopausal and early postmenopausal women, provided that the patient is not at a high CVD risk (as assessed by 10-year calculation tools). Transdermal oestrogens have a lower risk of thrombosis compared with oral regimens. Concerning progestogens, natural progesterone and dydrogesterone have a neutral effect on CVD risk factors. In any case, the decision for MHT should be individualized, tailored according to the symptoms, patient preference and the risk of CVD, thrombotic episodes and breast cancer.

Analysis of the long-term beneficial effects of menopausal hormone therapy on sleep quality and menopausal symptoms.

A large number of menopausal women report sleep disturbances along with psychological, somatic and urogenital menopausal symptoms. The aim of this study was to evaluate the efficacy of menopausal hormonal therapy (MHT) in improving subjective sleep quality and the severity of menopausal symptoms. An institutional ethics committee approved this retrospective chart review of 342 women treated with MHT for menopausal symptoms. Standard 28-day MHT consisted of the oral administration of 2 mg estradiol daily for 14 days, followed by 2 mg estradiol and 10 mg dydrogesterone daily for the remaining 14 days. A subgroup of 14 participants with a family history of cancer and mammography scores of 3 and above, received only tibolone 2.5 mg daily. Perceived sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI), while the assessment of menopausal symptoms was performed using the Kupperman Menopause Index (KMI) and menopause rating scale (MRS). Of the 342 patients, 79 were followed-up for 3 years. Compared to the baseline scores, the mean decrease in PSQI scores was 1.53±0.29 points (P<0.0001) at 1 month, 2.21±0.187 points (P<0.0001) at 2 months and 2.26±0.6 points (P<0.0001) after 3 years of MHT. The KMI scores also decreased by a mean of 6.37±1.59 points (P<0.0001) at 1 month and by 8.73±1.92 points after 3 years (P<0.0001). The MRS scores decreased by a mean of 3.56±1.05 points (P<0.0001) at 1 month and by 4.28±2.01 points (P<0.0001) after 3 years, as compared to the baseline scores. Patients receiving tibolone MHT did not report any improvement in sleep quality (P=0.956). On the whole, the findings of this study indicate that conventional MHT has a rapid and prolonged beneficial effect on self-reported sleep quality and menopausal symptoms in women. However, further clinical studies are warranted to compare the effects of different MHT regimens.

Menopausal hormone therapy and heart disease prevention: desired or valid?

Cardiovascular diseases are the main cause of death for women in older age groups. For many decades, specialists have tried to prevent their development by the use of estrogen. The review of the literature presents current data on the effect of menopausal hormone therapy (MHT) on the risk of cardiovascular complications. The results of the main randomized clinical and observational studies in this area, conducted over several decades, are discussed. We described the concept of “window of opportunities”, in accordance with which an improvement in cardiovascular prognosis can be expected only at the onset of MHT in women under the age of 60 years in early postmenopause (menopause duration &lt;10 years). There are experimental and clinical data explaining the different effects of estrogen on the cardiovascular prognosis in women of various age groups and different duration of postmenopause. The recommendations given in the review on the use of MHT are based on modern international guidelines.

MHT for cardiovascular disease prevention - pro

In women cardiovascular disease (CVD) accounts more than half of all deaths. There is strong evidence that cardiovascular effects of menopausal hormone therapy (MHT) are affected by age and/or time since menopause at the initiation of MHT (“timing effect”).

Effects of menopausal hormone therapy on bone and body composition

ZusammenfassungDie Wechseljahre sind durch tiefgreifende klinische und hormonelle Veränderungen gekennzeichnet. Ein Östrogenmangel führt zu einem beschleunigten Knochenverlust und erhöhtem Frakturrisiko. Parallel dazu deuten Verlaufs-Studien auf einen Anstieg der Adipositas mit einer Neigung zu mehr zentralem Fett sowie einen Verlust an Muskelmasse hin. Die post-menopausale Hormontherapie (MHT), die derzeit auf die symptomatische Linderung von Hitzewallungen und andere klimakterische Symptome beschränkt ist, hat sich als wirksam erwiesen, um die Knochendichte zu erhalten. Jüngste Daten der OsteoLaus-Kohorte, einer bevölkerungsbasierten Studie mit postmenopausalen Frauen im Alter von 50–80 Jahren, deuten darauf hin, dass zusätzlich ein günstiger Effekt auf die Mikroarchitektur der Knochen vermittelt wird. Darüber hinaus haben Frauen unter MHT, weniger androides und viszerales Fett, entsprechend der verfügbaren Daten aus anderen Studien. Die Physiopathologie dieses Zusammenhangs ist nicht vollständig geklärt und kann Änderungen des Energieverbrauchs durch Östrogene betreffen. Im Gegenteil scheint die Wirkung der MHT auf die Magermasse begrenzter zu sein und könnte mit spezifischen Arten MHT oder dem zeitlichen Einsatz der MHT in Verbindung gebracht werden. Interessanterweise ist die Entwicklung nach dem MHT-Entzug in verschiedenen Geweben nicht identisch, wobei der Verlust des Nutzens für das Fettgewebe schneller eintritt. In Anbetracht des erneuten Interesses von MHT, zumindest für Frauen in der frühen Postmenopause, können diese Daten bei der Erwägung einer MHT wertvoll sein.

Effect of Menopausal Hormone Therapy on Bone Mineral Density in Chinese Women: A 2-Year, Prospective, Open-Label, Randomized-Controlled Trial.

BackgroundThis study was designed to explore the effect of menopausal hormone therapy (MHT) on bone mineral density (BMD) in Chinese women.Material/MethodsThis was a prospective, open-label, randomized-controlled clinical trial. We randomly assigned 123 postmenopausal women to 3 groups: group A received 0.625 mg conjugated equine estrogen (CEE) plus 100 mg micronized progesterone (MP), group B received 0.3 mg CEE daily plus 100 mg MP, and group C received 0.625 mg CEE daily plus 10 mg dydrogesterone (DHG). All subjects received a 2-year intervention and drugs were given in a continuous sequential pattern.ResultsNinety-six patients were followed up. At 1 year, groups A and B gained 2.31% and 1.95% BMD, respectively (P<0.01); at 2 years, groups B and C gained 2.37% and 4.15% BMD (P<0.01) respectively. At 2 years, group A gained 3.28% BMD in the femoral neck and 3.77% BMD in Ward’s triangle (P<0.05). At 1 year, group B lost 2.14% BMD in the trochanter and 1.20% BMD in the total hip (P<0.05); at 2 years, group B lost 1.51% BMD in the total hip (P<0.01). ALP, Ca, P, and Ca/Cr levels were all decreased in the 3 groups (P<0.05). The changes in Cr level at 1 and 2 years were not significant when compared with baseline in all groups (P>0.05).ConclusionsBoth lower-dose and standard-dose CEE increased lumbar BMD, sustain femoral neck BMD, and Ward’s triangle BMD, while there was a reduced bone turnover rate. Standard-dose CEE combined with MP can increase BMD at these 2 sites. CEE combined with MP is recommended because it has better clinical benefits.

The Effects of Menopausal Hormone Therapy on Serum Level of C-reactive Protein in Postmenopausal Korean Women.

ObjectivesInflammation is a major mechanism underlying coronary heart disease (CHD) and C-reactive protein (CRP) is a marker of inflammation. When administered soon after menopause, menopausal hormone therapy (MHT) prevents CHD. This study was conducted to examine the impact of estrogen by administration route on CRP in postmenopausal Korean women using micronized progesterone (MP4) for endometrial protection.MethodsThis retrospective cohort study included 129 healthy women without CHD risk factors. Eighty-nine women took oral estrogen (conjugated equine estrogen, 0.625 mg/day or equivalent), and 40 women applied a 1.5-mg/day 0.1% percutaneous estradiol gel. MP4 was added in 82 women with an intact uterus. The CRP level was measured at baseline and three and six months after initiation of MHT.ResultsThe baseline characteristics were comparable between the MHT groups except current age and age at menopause. After controlling for age, menopausal age, body mass index, and basal CRP, no significant change in CRP was observed in the oral estrogen group (n = 29). Follow-up CRP levels were also similar to the baseline in the percutaneous estrogen group (n = 18). However, three-month CRP was significantly lower than six-month CRP, and there was a significant time trend within the percutaneous estrogen group. However, the group difference did not reach statistical significance. CRP also did not differ by addition of MP4 in either group.ConclusionsIn postmenopausal Korean women, no change in CRP was observed with oral estrogen, while percutaneous estrogen might decrease CRP. The estrogenic impacts were not influenced by adding MP4.

Menopausal hormone therapy and the incidence of carpal tunnel syndrome in postmenopausal women: Findings from the Women's Health Initiative.

ImportanceCarpal tunnel syndrome (CTS) is a common and debilitating condition that commonly affects postmenopausal women.ObjectiveTo determine the effect of menopausal hormone therapy (HT) in healthy postmenopausal women on CTS risk.DesignWe conducted a secondary analysis of the Women’s Health Initiative’s (WHI) HT trials linked to Medicare claims data. Separate intention-to-treat analyses were performed for the two trials; the conjugated equine estrogens alone (CEE alone) and the trial of CEE plus medroxyprogesterone acetate (MPA) trial. (ClinicalTrials.gov, NCT number): NCT00000611.SettingTwo randomized, double-blind, placebo-controlled trials conducted at 40 US clinical centers.ParticipantsThe sample size included in the analysis was 16,053 community-dwelling women aged ≥65 years at study entry or those who later aged into Medicare eligibility, and who were enrolled in Medicare (including Part A and/or Part B coverage).InterventionWomen with hysterectomy were randomized to 0.625 mg/d of conjugated equine estrogens (CEE) or placebo (n = 8376). Women without hysterectomy were randomized to estrogen plus progestin (E+P), given as CEE plus 2.5 mg/d of medroxyprogesterone acetate (n = 14203).Main outcome(s)The primary outcome was incident CTS and the secondary outcome was therapeutic CTS procedure occurring during the intervention phases of the trials.ResultsA total of 16,053 women were randomized in both trials. During mean follow up of 4.5 ± 2.8 years in the CEE trial (n = 6,833), there were 203 incident CTS cases in the intervention and 262 incident CTS cases in the placebo group (HR, 0.78; 95% CI, 0.65–0.94; P = 0.009). The CEE+MPA trial (n = 9,220) followed participants for a mean of 3.7 ± 2.3 years. There were 173 incident CTS cases in the intervention compared to 203 cases in the placebo group (HR, 0.80, 95% CI, 0.65–0.97; P = 0.027).ConclusionsThese findings suggest a protective effect of menopausal HT on the incidence of CTS among postmenopausal women. A potential therapeutic role for other forms of estrogen therapy in the management of CTS warrants future research.

The effects of menopausal hormone therapy on proinflammatory cytokines and immunoglobulins in perimenopausal patients with type 2 diabetes mellitus and chronic obstructive pulmonary disease (COPD)

Aim. To determine the effects of menopausal hormone therapy dosage on levels of proinflammatory cytokines and immunoglobulins in bodily fluids of patients with type 2 diabetes mellitus (DM) and chronic obstructive pulmonary disease (COPD) during perimenopause. Materials and methods. The study included 119 perimenopausal females with moderate type 2 DM and stable COPD with signs of menopausal syndrome. Cytokine levels in bronchoalveolar lavage fluid and blood serum were measured with flow cytofluorometry (Вeckman Coulter FC500, USA) using a multiplex kit for human cytokines (BMS810FF) in adherence to the manufacturer’s instructions. The lower limit of quantification was 2.5-52.7 pg/mL. The following cytokines were studied: IL-1β, IL-6, IL-8, TNF-α and IF-γ. The data was analyzed with Flow CytomixProver 3.0 manufacturer-licensed software package. IgМ, IgG and IgА in the blood serum (Vektor-Best, Russia) were detected using an immunoenzymatic assay (Stat Fax 3200Analyzer, Awareness Technology, USA). Menopausal hormone therapy (MHT) with 17 beta-estradiol/dydrogesterone (standard - 2 mg, low - 1 mg, ultralow - 0.5 mg): 0.5/2.5 (estradiol 0.5 mg/dydrogesterone 2.5 mg) - ultralow-dose MHT, 1/10 (estradiol 1 mg/dydrogesterone 10 mg) - low-dose MHT; 2/10 (estradiol 2 mg/dydrogesterone 10 mg) - standard-dose MHT. Саrbohydrate metabolism was assessed in three groups. Results and discussion. While 2/10 MHT yielded the most prominent decrease in IL-1β, IL-6, IL-8, TNF-α and IF-γ levels in bronchoalveolar lavage fluid and blood serum, the effect was statistically insignificant compared to 0.5/2.5 and 1/10 MHT. Initially decreased IgM, IgG and IgA levels were elevated in all the three dosage groups with no significant differences between them. As to carbohydrate metabolism target values of glycemia were achieved in all three groups taking MHT. Conclusion. Standard-, low - and ultralow-dose MHT has positive effects on levels of proinflammatory cytokines and immunoglobulins characteristic of the association between type 2 DM, COPD and menopausal syndrome. The differences between the three dosage groups were statistically insignificant. Different dosage of MHT with dydrogesterone provide for improving impaired carbohydrate metabolism.

Menopause and diabetes: EMAS clinical guide

IntroductionWhether menopause increases the risk of type 2 diabetes mellitus (T2DM) independently of ageing has been a matter of debate. Controversy also exists about the benefits and risks of menopausal hormone therapy (MHT) in women with T2DM. AimsTo summarise the evidence on 1) the effect of menopause on metabolic parameters and the risk of T2DM, 2) the effect of T2DM on age at menopause, 3) the effect of MHT on the risk of T2DM, and 4) the management of postmenopausal women with T2DM. Materials and methodsLiterature review and consensus of experts’ opinions. Results and conclusionMetabolic changes during the menopausal transition include an increase in and the central redistribution of adipose tissue, as well as a decrease in energy expenditure. In addition, there is impairment of insulin secretion and insulin sensitivity and an increase in the risk of T2DM. MHT has a favourable effect on glucose metabolism, both in women with and in women without T2DM, while it may delay the onset of T2DM. MHT in women with T2DM should be administered according to their risk of cardiovascular disease (CVD). In women with T2DM and low CVD risk, oral oestrogens may be preferred, while transdermal 17β-oestradiol is preferred for women with T2DM and coexistent CVD risk factors, such as obesity. In any case, a progestogen with neutral effects on glucose metabolism should be used, such as progesterone, dydrogesterone or transdermal norethisterone. Postmenopausal women with T2DM should be managed primarily with lifestyle intervention, including diet and exercise. Most of them will eventually require pharmacological therapy. The selection of antidiabetic medications should be based on the patient’s specific characteristics and comorbidities, as well on the metabolic, cardiovascular and bone effects of the medications.
