Non-hormonal treatment strategies for vasomotor symptoms: a critical review

Effectiveness and safety of fezolinetant in alleviating vasomotor symptoms linked to Menopause.: A systematic review and Meta-Analysis

BACKGROUND & OBJECTIVE

Vasomotor symptoms (VMS) are the most common symptoms during menopause including hot flushes and night sweats. They are highly disruptive to the quality of life. Fezolinetant is an FDA-approved non-hormonal selective neurokinin3 receptor antagonist for the treatment of VMS. In this study, we aim to assess the efficacy and safety of fezolinetant for VMS associated with menopause.

METHODS

Databases were searched until September 2023 for relevant studies comparing fezolinetant against placebo. Data was extracted into an online form and analyzed using RevMan (Version 5.4.1). The GRADE approach was conducted to evaluate the quality of evidence regarding efficacy outcomes. We included randomized controlled trials (RCTs) comparing fezolinetant to placebo in postmenopausal women experiencing VMS. Exclusion criteria comprised studies involving participants with contraindications to fezolinetant or those evaluating its efficacy for indications other than VMS associated with menopause.

RESULTS

Six studies were included in this study involving 3301 patients. Compared to placebo, fezolinetant reduced the frequency of VMS episodes from baseline (SMD = -0.64, 95 % CI [-0.77, -0.5]) and (SMD = -0.63, 95 % CI [-0.72, -0.53] at weeks 4 and 12 respectively. Additionally, fezolinetant reduced VMS severity score (SMD = -0.59, 95 %CI [-0.77, -0.42]) and (SMD = -0.4, 95 % CI [-0.54, -0.27]) at weeks 4 at 12 respectively. These reductions were positively reflected on Menopause specific quality of life score (SMD = -0.46, 95 %CI [-57, -0.34]), (SMD = -0.37, 95 %CI [-0.48, -0.25]) at weeks 4 and 12 respectively. Regarding safety analysis, fezolinetant showed increased risk for drug-related TEAEs (RR = 1.47, 95 %CI [1.06,2.04]), serious TEAEs (RR = 1.67, 95 %CI [1.09,2.55]), fatigue (RR = 4.05, 95 %CI [1.27,12.88]), arthralgia (RR = 2.83, 95 %CI [1.02,7.8]) and ALT or AST > 3 times (RR = 2, 95 %CI [1.12,3.57]), with no other statistically significant difference regarding other safety terms.

CONCLUSION

Fezolinetant has demonstrated efficacy in reducing the frequency and severity of VMS in postmenopausal women, leading to an improvement in their quality of life. These findings suggest that Fezolinetant may serve as a viable alternative to hormonal therapy for managing VMS.

Clinical and Treatment Considerations for the Pediatric and Aging Patients with Multiple Sclerosis

Chronologic aging is associated with multiple pathologic and immunologic changes that impact the clinical course of multiple sclerosis (MS). Clinical phenotypes evolve across the lifespan, from a highly inflammatory course in the very young to a predominantly neurodegenerative phenotype in older patients. Thus, unique clinical considerations arise for the diagnosis and management of the two age extremes of pediatric and geriatric MS populations. This review covers epidemiology, diagnosis, and treatment strategies for these populations with nuanced discussions on therapeutic approaches to effectively care for patients living with MS at critical transition points during their lifespan.

Weight gain in menopause: systematic review of adverse events in women treated with black cohosh

Weight gain is a frequent problem in perimenopausal and postmenopausal women. Cimicifuga racemosa (CR) is a popular treatment option for menopausal symptoms. The aim of this review was to investigate whether there is scientific evidence that CR causes weight gain. We searched our database for medically confirmed, spontaneous adverse events regarding weight gain, literature for case reports and randomized controlled trials. Thirty cases in total were spontaneously reported in 15 years. The causality was not considered certain/likely in any of the cases. A nurse (consumer) assessed the causality as possible. Only one case was published in the literature. However, no change in body fat composition was reported, and the causality seems unlikely. Of the 31 identified studies, 17 were double-blind placebo-controlled, five were double-blind reference-controlled and nine were open reference-controlled. In total, 1839 women were treated with CR for up to 12 months. Two studies reported weight gain as an adverse event; however, no significant differences in weight changes were observed between the groups. One case of weight gain (about 2 kg) was reported, but the authors did not specify in which treatment group. In conclusion, this study provides no scientific evidence that the use of Cimicifuga racemosa causes weight gain in menopausal women.

Effects of Menopause in Women With Multiple Sclerosis: An Evidence-Based Review

Over two thirds of all individuals who develop multiple sclerosis (MS) will be women prior to the age of menopause. Further, an estimated 30% of the current MS population consists of peri- or postmenopausal women. The presence of MS does not appear to influence age of menopausal onset. In clinical practice, symptoms of MS and menopause can frequently overlap, including disturbances in cognition, mood, sleep, and bladder function, which can create challenges in ascertaining the likely cause of symptoms to be treated. A holistic and comprehensive approach to address these common physical and psychological changes is often suggested to patients during menopause. Although some studies have suggested that women with MS experience reduced relapse rates and increased disability progression post menopause, the data are not consistent enough for firm conclusions to be drawn. Mechanisms through which postmenopausal women with MS may experience disability progression include neuroinflammation and neurodegeneration from age-associated phenomena such as immunosenescence and inflammaging. Additional effects are likely to result from reduced levels of estrogen, which affects MS disease course. Following early retrospective studies of women with MS receiving steroid hormones, more recent interventional trials of exogenous hormone use, albeit as oral contraceptive, have provided some indications of potential benefit on MS outcomes. This review summarizes current research on the effects of menopause in women with MS, including the psychological impact and symptoms of menopause on disease worsening, and the treatment options. Finally, we highlight the need for more inclusion of MS patients from underrepresented racial and geographic groups in clinical trials, including among menopausal women.

Chinese Medicines Improve Perimenopausal Symptoms Induced by Surgery, Chemoradiotherapy, or Endocrine Treatment for Breast Cancer

The application of surgery, chemoradiotherapy, and endocrine treatment successfully increases survival rates of breast cancer patients. However, perimenopausal symptoms, the main side effects of these treatments, often afflict patients and reduce their quality of life. Perimenopausal symptoms include vasomotor symptoms, sleep problems, arthromuscular symptoms, and osteoporosis. Currently, there are no satisfactory treatments for perimenopausal symptoms that result from these treatments. Therefore, alternative and complementary therapies including herbal medicines represented by Chinese medicines (CMs), acupuncture, massage, and psychotherapy are increasingly being expected and explored. In this paper, we review the effects and potentials of several CM formulae, along with some active ingredients or fractions from CMs, Chinese herbal extracts, and other herbal medicines, which have drawn attention for improving perimenopausal symptoms in breast cancer patients. We also elaborate their possible mechanisms. Moreover, further studies for evaluation of standardized clinical efficacy should be scientifically well-designed and continuously performed to investigate the efficacy and mechanisms of CMs for perimenopausal symptoms due to breast cancer therapy. The safety and value of estrogen-containing CMs for breast cancer should also be clarified.

Role of paroxetine in the management of hot flashes in gynecological cancer survivors: Results of the first randomized single-center controlled trial

OBJECTIVES

To examine the effects of paroxetine supplementation on hot flashes and sleep in gynecological cancer survivors.

METHODS

In a randomized, double-blind, placebo-controlled study, postmenopausal women with a prior history of stage 0-III gynecological cancer who had completed active cancer treatment (including hormonal therapy) were randomly assigned 1:1 to either 7.5mg oral paroxetine or placebo daily for 16weeks. Sleep and hot flashes were assessed at baseline, week 4 and week 16.

RESULTS

Eighty women (91%) completed the study. We found out a statistically significant difference in weekly reductions in VMS frequency and severity for paroxetine 7.5mg than for placebo on week 4 and 16. Regarding sleep characteristics, the analysis of data through week 16 reported a statistically significant reduction in the number of nighttime awakenings attributed to VMS among participants receiving paroxetine than among participants receiving placebo on baseline and weeks. The duration of sleep per night increased significantly more among participants receiving paroxetine than among those receiving placebo at all post baseline time points. No significant differences in sleep-onset latency were noted between the two treatment arms during the course of the study. Paroxetine was well-tolerated with a high level of compliance. In our cohort of patients, no serious adverse events have been reported.

CONCLUSIONS

This is the first randomized placebo-controlled study in gynecological cancer survivors that demonstrates that paroxetine significantly reduces hot flashes in weekly frequency and severity and the number of nighttime awakenings attributed to vasomotor symptoms, increasing sleep duration.

Do Selective Serotonin Reuptake Inhibitors (SSRIs) Cause Fractures?

Recent meta-analyses report a 70 % increase in fracture risk in selective serotonin reuptake inhibitor (SSRI) users compared to non-users; however, included studies were observational and limited in their ability to establish causality. Here, we use the Bradford Hill criteria to explore causality between SSRIs and fractures. We found a strong, consistent, and temporal relationship between SSRIs and fractures, which appears to follow a biological gradient. However, specificity and biological plausibility remain concerns. In terms of specificity, the majority of available data have limitations due to either confounding by indication or channeling bias. Self-controlled case series address some of these limitations and provide relatively strong observational evidence for a causal relationship between SSRIs and fracture. In doing so, they suggest that falls contribute to fractures in SSRI users. Whether there are also underlying changes in skeletal properties remains unresolved. Initial studies provide some evidence for skeletal effects of SSRIs; however, the pathways involved need to be established before biological plausibility can be accepted. As the link between SSRIs and fractures is based on observational data and not evidence from prospective trials, there is insufficient evidence to definitively determine a causal relationship and it appears premature to label SSRIs as a secondary cause of osteoporosis. SSRIs appear to contribute to fracture-inducing falls, and addressing any fall risk associated with SSRIs may be an efficient approach to reducing SSRI-related fractures. As fractures stemming from SSRI-induced falls are more likely in individuals with compromised bone health, it is worth considering bone density testing and intervention for those presenting with risk factors for osteoporosis.

Botanicals and Their Bioactive Phytochemicals for Women's Health

Botanical dietary supplements are increasingly popular for women's health, particularly for older women. The specific botanicals women take vary as a function of age. Younger women will use botanicals for urinary tract infections, especially Vaccinium macrocarpon (cranberry), where there is evidence for efficacy. Botanical dietary supplements for premenstrual syndrome (PMS) are less commonly used, and rigorous clinical trials have not been done. Some examples include Vitex agnus-castus (chasteberry), Angelica sinensis (dong quai), Viburnum opulus/prunifolium (cramp bark and black haw), and Zingiber officinale (ginger). Pregnant women have also used ginger for relief from nausea. Natural galactagogues for lactating women include Trigonella foenum-graecum (fenugreek) and Silybum marianum (milk thistle); however, rigorous safety and efficacy studies are lacking. Older women suffering menopausal symptoms are increasingly likely to use botanicals, especially since the Women's Health Initiative showed an increased risk for breast cancer associated with traditional hormone therapy. Serotonergic mechanisms similar to antidepressants have been proposed for Actaea/Cimicifuga racemosa (black cohosh) and Valeriana officinalis (valerian). Plant extracts with estrogenic activities for menopausal symptom relief include Glycine max (soy), Trifolium pratense (red clover), Pueraria lobata (kudzu), Humulus lupulus (hops), Glycyrrhiza species (licorice), Rheum rhaponticum (rhubarb), Vitex agnus-castus (chasteberry), Linum usitatissimum (flaxseed), Epimedium species (herba Epimedii, horny goat weed), and Medicago sativa (alfalfa). Some of the estrogenic botanicals have also been shown to have protective effects against osteoporosis. Several of these botanicals could have additional breast cancer preventive effects linked to hormonal, chemical, inflammatory, and/or epigenetic pathways. Finally, although botanicals are perceived as natural safe remedies, it is important for women and their healthcare providers to realize that they have not been rigorously tested for potential toxic effects and/or drug/botanical interactions. Understanding the mechanism of action of these supplements used for women's health will ultimately lead to standardized botanical products with higher efficacy, safety, and chemopreventive properties.

Risk of mortality with concomitant use of tamoxifen and selective serotonin reuptake inhibitors: multi-database cohort study

OBJECTIVE

 To compare differences in mortality between women concomitantly treated with tamoxifen and selective serotonin reuptake inhibitors (SSRIs) that are potent inhibitors of the cytochrome-P450 2D6 enzyme (CYP2D6) versus tamoxifen and other SSRIs.

DESIGN

 Population based cohort study.

SETTING

 Five US databases covering individuals enrolled in private and public health insurance programs from 1995 to 2013.

PARTICIPANTS

 Two cohorts of women who started taking tamoxifen. In cohort 1, women started taking an SSRI during tamoxifen treatment. In cohort 2, women were already taking an SSRI when they started taking tamoxifen.

MAIN OUTCOME MEASURES

 All cause mortality in each cohort in women taking SSRIs that are potent inhibitors of CYP2D6 (paroxetine, fluoxetine) versus other SSRIs. Propensity scores were used to match exposure groups in a variable ratio fashion. Results were measured separately for each cohort and combined hazard ratios calculated from Cox regression models across the two cohorts with random effects meta-analysis.

RESULTS

 There were 6067 and 8465 new users of tamoxifen in cohorts 1 and 2, respectively. Mean age was 55. A total of 991 and 1014 deaths occurred in cohorts 1 and 2 during a median follow-up of 2.2 (interquartile range 0.9-4.5) and 2.0 (0.8-3.9) years, respectively. The pooled hazard ratio for death for potent inhibitors (rate 58.6/1000 person years) compared with other SSRIs (rate 57.9/1000 person years) across cohorts 1 and 2 was 0.96 (95% confidence interval 0.88 to 1.06). Results were consistent across sensitivity analyses.

CONCLUSION

 Concomitant use of tamoxifen and potent CYP2D6 inhibiting SSRIs versus other SSRIs was not associated with an increased risk of death.

Effects of low-dose paroxetine 7.5 mg on weight and sexual function during treatment of vasomotor symptoms associated with menopause

Supplemental digital content is available in the text.

Objective

Two phase 3, randomized, placebo-controlled trials demonstrated that low-dose paroxetine 7.5 mg reduced the frequency and severity of vasomotor symptoms (VMS) associated with menopause and had a favorable tolerability profile. The impact of paroxetine 7.5 mg on body weight and sexual function was evaluated in a pooled analysis.

Methods

Postmenopausal women aged 40 years or older who had moderate to severe VMS were randomly assigned to receive paroxetine 7.5 mg or placebo once daily for 12 or 24 weeks. Assessments included changes in body mass index (BMI) and weight, Arizona Sexual Experiences Scale score, Hot Flash–Related Daily Interference Scale sexuality subscore, and adverse events related to weight or sexual dysfunction.

Results

Pooled efficacy and safety populations comprised 1,174 and 1,175 participants, respectively. Baseline values were similar for median weight (∼75 kg), median BMI (∼28 kg/m²), and the proportion of women with sexual dysfunction (∼58%). No clinically meaningful or statistically significant changes from baseline in weight or sexual function assessments occurred in the paroxetine 7.5 mg group. Small but statistically significant increases in weight and BMI were observed in the placebo group only on week 4. No significant difference between treatment groups was observed in the proportion of participants who had 7% or higher gain in body weight on week 4, 12, or 24. Rates of adverse events suggestive of sexual dysfunction were low and similar in both treatment groups.

Conclusions

Paroxetine 7.5 mg does not cause weight gain or negative changes in libido when used to treat menopause-associated VMS in postmenopausal women.

Menopause

Menopause is an inevitable component of ageing and encompasses the loss of ovarian reproductive function, either occurring spontaneously or secondary to other conditions. It is not yet possible to accurately predict the onset of menopause, especially early menopause, to give women improved control of their fertility. The decline in ovarian oestrogen production at menopause can cause physical symptoms that may be debilitating, including hot flushes and night sweats, urogenital atrophy, sexual dysfunction, mood changes, bone loss, and metabolic changes that predispose to cardiovascular disease and diabetes. The individual experience of the menopause transition varies widely. Important influential factors include the age at which menopause occurs, personal health and wellbeing, and each woman's environment and culture. Management options range from lifestyle assessment and intervention through to hormonal and non-hormonal pharmacotherapy, each of which has specific benefits and risks. Decisions about therapy for perimenopausal and postmenopausal women depend on symptomatology, health status, immediate and long-term health risks, personal life expectations, and the availability and cost of therapies. More effective and safe therapies for the management of menopausal symptoms need to be developed, particularly for women who have absolute contraindications to hormone therapy.

[Hormone replacement therapy in menopause]

Although estrogen has been clinically available for more than six decades, women have been confused by different opinions regarding the risks and benefits of menopausal hormone therapy (HT), estrogen therapy (ET), and estrogen-progestin therapy (EPT). The publication of randomized controlled trials (RCTs), notably, the Heart and Estrogen/progestin Replacement Study (HERS) and Women's Health Initiative (WHI), has intensified the risk vs. benefit controversy. Millions of women are treated with HT for relief of menopausal symptoms, including vasomotor flushes and sweats, for which estrogen is uniquely and highly effective. Others may continue longer-term treatment in the hope that HT will help to prevent chronic disease. The preservation of bone mass with continuing estrogen therapy and reduction of subsequent risk of fracture is well established. Observational studies of the metabolic and vascular effects of estrogens have suggested a potential benefit in reducing the risk of vascular disease, but recently published randomized controlled trials demonstrated no evidence of benefit in women with established vascular disease or in apparently healthy women. The increased risks of breast cancer and thromboembolic disease have been confirmed in these trials, with evidence of increased risk of stroke. The absolute incidence of an adverse event is low, and the risk of stroke in an individual woman in a single year is very small, but with long-term use, the risks are cumulative over time. The risk-benefit balance needs to be individualized for each woman.

Caring for the breast cancer survivor’s health and well-being

The breast cancer care continuum entails detection, diagnosis, treatment, and survivorship. During this time, focus on the whole woman and medical concerns beyond the breast cancer diagnosis itself is essential. In this comprehensive review, we critically review and evaluate recent evidence regarding several topics pertinent to and specific for the woman living with a prior history of breast cancer. More specifically, we discuss the most recent recommendations for contraceptive options including long-acting reversible contraception and emergency contraception, fertility and pregnancy considerations during and after breast cancer treatment, management of menopausal vasomotors symptoms and vulvovaginal atrophy which often occurs even in young women during treatment for breast cancer. The need to directly query the patient about these concerns is emphasized. Our focus is on non-systemic hormones and non-hormonal options. Our holistic approach to the care of the breast cancer survivor includes such preventive health issues as sexual and bone health,which are important in optimizing quality of life. We also discuss strategies for breast cancer recurrence surveillance in the setting of a prior breast cancer diagnosis. This review is intended for primary care practitioners as well as specialists caring for female breast cancer survivors and includes key points for evidence-based best practice recommendations.

A review of paroxetine for the treatment of vasomotor symptoms

BACKGROUND

Studies in recent years have exposed concerns about the safety of hormone replacement therapy (HRT) in the treatment of vasomotor symptoms (VMS) in menopausal women. Numerous studies have examined the use of antidepressants for relief of VMS. Despite recommendations to deny approval of paroxetine mesylate (Brisdelle™) for the treatment of VMS, the Food and Drug Administration (FDA) recently granted it approval for this indication.

OBJECTIVE

To evaluate all published literature examining use of paroxetine salts (mesylate and hydrochloride) in the treatment of menopausal VMS.

METHODS

Both PubMed and International Pharmaceutical Abstracts (IPA) were searched using the keywords hot flashes, vasomotor symptoms, menopause, and paroxetine. In PubMed, MeSH terms were used for paroxetine, menopause, and hot flashes. Searches were limited to humans, English language, and clinical trial design. The references for each study identified in this search process were examined in order to locate any additional relevant articles.

RESULTS

Compared with placebo, paroxetine salts offer a modest benefit in the treatment of menopausal VMS reducing the frequency and severity of weekly hot flashes.

CONCLUSION

Paroxetine (mesylate or hydrochloride) is an effective alternative to HRT for the reduction in VMS in menopausal women. Future head-to-head studies with active medications are needed in order to identify the best algorithm of treatment for this condition.

New Pharmacological Therapies for Vasomotor Symptom Management

Objective: To review 2 recently approved therapies for vasomotor symptoms (VMSs) of menopause. Data Sources: PubMed searches (June 2003 to May 2014) were conducted using the keywords paroxetine vasomotor and bazedoxifene vasomotor. References from relevant articles were reviewed for pertinent citations that were not identified in the PubMed search. Study Selection and Data Extraction: Phase 3 clinical trials of recently approved hormonal and nonhormonal therapies for the treatment of VMSs of menopause were selected. Studies that evaluated the use of paroxetine mesylate or bazedoxifene (BZA)/conjugated estrogens (CEs) for VMSs were included. Data Synthesis: Four studies for BZA/CEs were identified. One published report of low-dose paroxetine mesylate was identified that was a combined analysis of 2 phase 3 studies. Both agents significantly decrease the incidence of hot flushes compared with placebo and are approved for the treatment of moderate to severe VMSs associated with menopause. BZA/CEs is only approved for women with an intact uterus. In all circumstances, the use of BZA/CEs should be limited to the shortest duration possible. Paroxetine mesylate was not studied head-to-head against hormone therapy, but the magnitude of its effect on VMSs is less than expected with hormone therapy. Conclusions: BZA/CEs is an effective hormonal therapy for treating VMSs in women with an intact uterus. Paroxetine mesylate is the first nonhormonal therapy that the FDA has approved for VMSs, making both viable options for the treatment of VMSs of menopause.

Acupuncture for menopausal vasomotor symptoms: study protocol for a randomised controlled trial

BACKGROUND

Hot flushes and night sweats (vasomotor symptoms) are common menopausal symptoms, often causing distress, sleep deprivation and reduced quality of life. Although hormone replacement therapy is an effective treatment, there are concerns about serious adverse events. Non-hormonal pharmacological therapies are less effective and can also cause adverse effects. Complementary therapies, including acupuncture, are commonly used for menopausal vasomotor symptoms. While the evidence for the effectiveness of acupuncture in treating vasomotor symptoms is inconclusive, acupuncture has a low risk of adverse effects, and two small studies suggest it may be more effective than non-insertive sham acupuncture. Our objective is to assess the efficacy of needle acupuncture in improving hot flush severity and frequency in menopausal women. Our current study design is informed by methods tested in a pilot study.

METHODS/DESIGN

This is a stratified, parallel, randomised sham-controlled trial with equal allocation of participants to two trial groups. We are recruiting 360 menopausal women experiencing a minimum average of seven moderate hot flushes a day over a seven-day period and who meet diagnostic criteria for the Traditional Chinese Medicine diagnosis of Kidney Yin deficiency. Exclusion criteria include breast cancer, surgical menopause, and current hormone replacement therapy use. Eligible women are randomised to receive either true needle acupuncture or sham acupuncture with non-insertive (blunt) needles for ten treatments over eight weeks. Participants are blinded to treatment allocation. Interventions are provided by Chinese medicine acupuncturists who have received specific training on trial procedures. The primary outcome measure is hot flush score, assessed using the validated Hot Flush Diary. Secondary outcome measures include health-related quality of life, anxiety and depression symptoms, credibility of the sham treatment, expectancy and beliefs about acupuncture, and adverse events. Participants will be analysed in the groups in which they were randomised using an intention-to-treat analysis strategy.

DISCUSSION

Results from this trial will significantly add to the current body of evidence on the role of acupuncture for vasomotor symptoms. If found to be effective and safe, acupuncture will be a valuable additional treatment option for women who experience menopausal vasomotor symptoms.

Effects of isoflavones and amino acid therapies for hot flashes and co-occurring symptoms during the menopausal transition and early postmenopause: a systematic review

AIMS

Review controlled clinical trials of isoflavones and amino acid preparation effects on hot flashes and at least one other symptom including mood, sleep, pain, and cognitive function that women report during the menopausal transition and early postmenopause.

METHODS

An experienced reference librarian searched PubMed/Medline, CINAHL Plus, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, AMED, and Alt-Health Watch for English-language randomized controlled trials between 2004 and July 2011. Seventeen trials of isoflavones and amino acid effects on hot flashes and one additional symptom were identified.

RESULTS

In five trials of soy isoflavone preparations, two (6g soy germ extract and 25 g soy protein in soy nuts) significantly decreased hot flashes, but no other symptoms. In the seven trials of other isoflavones, six significantly reduced hot flashes; in addition, red clover (80 mg) significantly reduced mood symptoms; Rexflavone (350 mg) for women with Kupperman Index>20 significantly reduced sleep symptoms; two trials had significant reductions for pain: isoflavone powder (90 mg) and red clover (80 mg). The only trial in this systematic review that significantly reduced cognitive symptoms was red clover (80 mg). In one trial, red clover isoflavone (80 mg/day) significantly relieved hot flashes, mood, pain, and cognitive symptoms. Amino acids yielded no significant results. Equol supplements of 30 mg/day for non-Equol producing women significantly reduced mood symptoms in one trial. The magnolia bark extract combination significantly reduced hot flashes, mood, and sleep symptoms.

CONCLUSIONS

Isoflavone trials yielded significant reductions on hot flashes and co-occurring symptoms during the menopausal transition and postmenopause, but studies require replication with larger sample sizes and attention to measurement of outcomes.

Low-dose paroxetine 7.5 mg for menopausal vasomotor symptoms: two randomized controlled trials

OBJECTIVE

The efficacy and safety of low-dose paroxetine 7.5 mg for the treatment of menopausal vasomotor symptoms were evaluated in two multicenter, double-blind, placebo-controlled, phase 3 studies of 12 and 24 weeks' duration.

METHODS

Postmenopausal women were randomly assigned 1:1 to receive paroxetine 7.5 mg or placebo once daily. The four primary efficacy endpoints included mean changes in the frequency and severity of moderate to severe vasomotor symptoms on weeks 4 and 12; an additional endpoint was persistence of treatment benefit on week 24.

RESULTS

Five hundred ninety-one participants were randomly assigned to treatment with paroxetine 7.5 mg, and 593 participants were randomly assigned to treatment with placebo. All primary endpoints were met in the 24-week study; three of four primary endpoints were met in the 12-week study. In both studies, paroxetine 7.5 mg significantly reduced the mean weekly vasomotor symptom frequency compared with placebo on week 4 (P < 0.0001 for both studies) and week 12 (P = 0.0090, 12-wk study; P = 0.0001, 24-wk study). Mean weekly reduction in vasomotor symptom severity was significantly greater for paroxetine 7.5 mg than for placebo on week 4 (P = 0.0048) in the 12-week study and on week 4 (P = 0.0452) and week 12 (P = 0.0114) in the 24-week study. Persistence of treatment benefit was demonstrated in the 24-week study. Most treatment-emergent adverse events were mild or moderate in severity. No clinically significant changes in laboratory values or vital signs were noted, and no short-term discontinuation of symptoms followed treatment cessation.

CONCLUSIONS

Paroxetine 7.5 mg is well-tolerated, is effective in reducing the frequency and severity of menopausal vasomotor symptoms, and demonstrates persistence of treatment benefit through 24 weeks of treatment.

Alternatives to hormone therapy for hot flashes: many choices but science is lacking

CLINICAL SCENARIO

A 51-year-old postmenopausal third-grade teacher requests help for her hot flashes. She finds them especially troubling as she stands in front of her class and starts sweating. Although one student offers her tissues, others make fun of her--disrupting the class. Her sleep is interrupted several times a night. She refuses to use any form of estrogen because her mother died of breast cancer at the age of 60 years. Perhaps alternative therapies can help her.

SSRIs for hot flashes: a systematic review and meta-analysis of randomized trials

BACKGROUND

Hot flashes are the most commonly reported vasomotor symptom during the peri- and early post-menopausal period.

OBJECTIVES

To systematically review, appraise and summarize the evidence of the impact of different SSRIs on peri-menopausal hot flashes in healthy women in randomized, controlled trials.

METHODS

A comprehensive literature search was conducted of MEDLINE™, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science and Scopus through March 2013. Two independent reviewers selected studies and extracted data. Random effects meta-analysis was used to pool outcomes across studies, and Bayesian mixed treatment methods were used to rank SSRIs in terms of effectiveness.

RESULTS

We included a total of 11 randomized controlled trials with good methodological quality enrolling 2,069 menopausal and post-menopausal women (follow-up 1-9 months, mean age 36-76 years, mean time since menopause 2.3-6.6 years). Compared with placebo, SSRIs were associated with a statistically significant decrease in hot flash frequency (difference in means -0.93; 95 % CI -1.46 to -0.37; I(2) = 21 %) and severity assessed by various scales (standardized difference in means -0.34; 95 % CI -0.59 to -0.10; I(2) = 47 %). Adverse events did not differ from placebo. Mixed treatment comparison analysis demonstrated the superiority of escitalopram compared to other SSRIs in terms of efficacy.

CONCLUSION

SSRI use is associated with modest improvement in the severity and frequency of hot flashes but can also be associated with the typical profile of SSRI adverse effects.

Menopause in multiple sclerosis: therapeutic considerations

While the onset of multiple sclerosis (MS) typically occurs during the childbearing years, many women living with MS are of perimenopausal age. There is frequent overlap between menopausal and MS-related symptoms and co-morbidities (e.g. sexual dysfunction, mood disorders and bladder function). Furthermore, some MS symptoms may be exacerbated by perimenopausal changes such as hot flashes or sleep disturbance. The MS neurologist may frequently be the first to become aware of these symptoms and to play a role in monitoring and managing them. In this review, we describe immunological and neurologic changes at menopause as they may impact MS. We then review common symptoms, including fatigue, depression, sexual function, pain and insomnia, and provide both behavioral and pharmacological suggestions for their management. Next, we discuss the need for osteoporosis and cancer screening in perimenopausal women with MS. Finally, we highlight important research gaps, including what effect, if any, the menopausal transition may play on MS disease course as well as the potential modulatory role of hormone replacement therapies.

Risk factors, pathophysiology, and treatment of hot flashes in cancer

Hot flashes are prevalent and severe symptoms that can interfere with mood, sleep, and quality of life for women and men with cancer. The purpose of this article is to review existing literature on the risk factors, pathophysiology, and treatment of hot flashes in individuals with cancer. Electronic searches were conducted to identify relevant English-language literature published through June 15, 2012. Results indicated that risk factors for hot flashes in cancer include patient-related factors (eg, age, race/ethnicity, educational level, smoking history, cardiovascular risk including body mass index, and genetics) and disease-related factors (eg, cancer diagnosis and dose/type of treatment). In addition, although the pathophysiology of hot flashes has remained elusive, these symptoms are likely attributable to disruptions in thermoregulation and neurochemicals. Therapies that have been offered or tested fall into 4 broad categories: pharmacological, nutraceutical, surgical, and complementary/behavioral strategies. The evidence base for this broad range of therapies varies, with some treatments not yet having been fully tested or showing equivocal results. The evidence base surrounding all therapies is evaluated to enhance hot flash treatment decision-making by clinicians and patients.

Serotonin and Female Psychopathology

There are sex differences in the prevalence and presentation of many psychiatric disorders. Various trends in symptomatology have emerged that are thought to be linked to periods of hormonal fluctuations such as with menses, pregnancy or menopause. With data from animal and human studies, it has become clear that there is an important interplay between the serotonergic system and gonadal hormones. The majority of the research to date has focused on the influence that estrogen has within the CNS and, in particular, how it leads to an overall increase in serotonin synthesis and availability. In reviewing this female-specific topic we hope to raise awareness to sex/gender differences in psychopathology, help identify at-risk populations and consider development of new treatment options. Future research will also need to consider the influence that progesterone and oxytocin may have on sex-specific psychopathology as well as incorporate neuroimaging and consider the influence of hormones on the serotonergic system at a genetic level.

Red scrotum syndrome: idiopathic neurovascular phenomenon or steroid addiction?

Background Red scrotum syndrome (RSS) is not infrequent but is often misdiagnosed or underdiagnosed, and seldom reported. The exact etiopathogeneis is still unknown but it almost always follows the prolonged application of topical corticosteroids and is characterised by persistent erythema of the scrotum, associated with severe itching, hyperalgesia and a burning sensation. Objective: To evaluate the clinicoepidemiological profile and assess the efficacy of various treatment modalities in addition to corticosteroid abstinence in the treatment of RSS. Methods: Twelve patients with RSS, who presented to us during 2010 and 2011, were identified, and various aspects of their illness and treatment were studied. Patch testing was performed in all patients. A skin biopsy was done in seven patients. Results: The average age of the patients was 45.83 years (26–62 years). The average duration of illness or the duration of topical steroid use was 27.41 months (6–56 months). Psychiatric comorbidities were seen in 9 (75%) out of 12 patients. Histopathology revealed features resembling erythematotelengiectatic rosacea in four of the biopsied patients. Patch test results were negative. All patients reported improvement of their symptoms within 4 weeks of starting doxycycline with amitriptyline or pregabalin; the treatment had to be continued for 3–4 months. Conclusions: RSS appears to be a manifestation of corticosteroid misuse rather than a primary disease. We suggest that RSS is a rosacea-like dermatosis or steroid-induced rebound vasodilation based on clinical and histopathological features. Our patients responded to cessation of steroids and doxycycline in combination with amitryptaline or pregabalin.

Psychotropic medications and other non-hormonal treatments for premenstrual disorders

Selective serotonin re-uptake inhibitors have well-established efficacy for severe premenstrual syndrome and premenstrual dysphoric disorder. Efficacy has been reported with both continuous dosing (all cycle) and intermittent or luteal phase dosing (from ovulation to menses). Efficacy may be less with intermittent dosing, particularly for premenstrual physical symptoms. The efficacy of symptom-onset dosing (medication taken only on luteal days when symptoms occur) needs further systematic study. Women going through the menopausal transition may need to adjust their antidepressant dosing regimen due to the change in frequency of menstruation. Anxiolytics, calcium, chasteberry and cognitive-behaviour therapy may also have a role in the treatment of premenstrual symptoms.

Effective and clinically meaningful non-hormonal hot flash therapies

Although many non-hormonal compounds have shown statistically significant benefit over placebo in hot flash randomized controlled trials (RCTs), these studies have varied considerably in basic methodology making it challenging to deduce which compounds have the greatest potential to provide clinically meaningful benefit. This review used evidence-based methodology closely mirroring the FDA and EMEA guidelines as a template to identify "well-designed" RCTs from which effective and clinically meaningful non-hormonal hot flash therapies could be identified. In addition, pertinent safety information was reviewed. Out of 3548 MEDLINE citations and abstracts, 51 well-designed hot flash RCTs were identified. From these trials, gabapentin, oxybutynin ER, desvenlafaxine, soy-derived isoflavones and black cohosh each showed a clinically meaningful treatment effect in at least 1 RCT. Among these 5 compounds, only gabapentin demonstrated consistent and statistically significant benefit over placebo in all of its well-designed RCTs. Desvenlafaxine, soy-derived isoflavones, and black cohosh demonstrated statistically significant benefit over placebo in 75%, 21%, and 17% of the well-designed RCTs for each compound, respectively. There was only 1 well-designed RCT using oxybutynin ER, which showed it to have a robust and clinically meaningful benefit. In terms of safety, there have been cardiovascular risks associated with desvenlafaxine use in postmenopausal women with hot flashes. The use of anticonvulsants, in general, has been associated with an absolute 0.21% increase in suicidal thoughts and behavior. Further research is needed with several of these nonhormonal compounds to replicate these findings and to also directly compare their efficacy and tolerability with those of hormone replacement therapy.

Tissue-Specific Effects of Loss of Estrogen during Menopause and Aging

The roles of estrogens have been best studied in the breast, breast cancers, and in the female reproductive tract. However, estrogens have important functions in almost every tissue in the body. Recent clinical trials such as the Women's Health Initiative have highlighted both the importance of estrogens and how little we know about the molecular mechanism of estrogens in these other tissues. In this review, we illustrate the diverse functions of estrogens in the bone, adipose tissue, skin, hair, brain, skeletal muscle and cardiovascular system, and how the loss of estrogens during aging affects these tissues. Early transcriptional targets of estrogen are reviewed in each tissue. We also describe the tissue-specific effects of selective estrogen receptor modulators (SERMs) used for the treatment of breast cancers and postmenopausal symptoms.
