Antidepressants during and after Menopausal Transition: A Systematic Review and Meta-Analysis

Sleep disturbance associated with the menopause

IMPORTANCE AND OBJECTIVES

Sleep disturbance is one of the most common and debilitating symptoms experienced by women during the menopause transition. However, there are currently no therapies specifically approved for sleep disturbance associated with the menopause. Here, we consider how to characterize sleep disturbance associated with the menopause and discuss its etiology, including the latest advances in our understanding of the neuronal circuits that regulate reproduction, body temperature, sleep, and mood; and reflect on its impact on women's health and well-being. We also examine the current treatment landscape and look to the future of treatment for this condition.

METHODS

We conducted a review of the literature and combined this with discussion with experts in the fields of sleep and menopause as well as experiences from our own clinical practices.

DISCUSSION AND CONCLUSIONS

Sleep disturbance associated with the menopause is characterized by frequent night-time awakenings and increased awake time after sleep onset. Its impacts are wide-ranging, negatively affecting health as well as personal and social relationships, productivity, and work performance. There is currently an unmet need for effective, safe, and well-tolerated treatments to address this important symptom, and wider recognition of the association between sleep disturbances and the menopause is needed. Sleep disturbances associated with the menopause can result from hormone changes as well as vasomotor and mood symptoms. Growing research has contributed to our knowledge of the role of hypothalamic estrogen-sensitive kisspeptin/neurokinin B/dynorphin neurons. These neurons are thought to integrate the gonadotropin-releasing hormone pathway and the pathways responsible for the homeostatic control of body temperature and the circadian regulation of sleep-wake cycles. Understanding these neurons offers the potential to create treatments that target a key cause of sleep disturbance associated with the menopause. Further research to understand their etiology and characterize the neuronal circuits responsible could benefit the development of these targeted treatment approaches.

Ameliorative effect of α-tocopherol and tocotrienol-rich palm oil extract on menopause-associated mood disorder in ovariectomized mice

Menopause-associated mood disorder is characterized by emotional depression, anxiety, and stress, which accompany hypogonadism in women in the menopausal phase. The current treatment for menopause-associated mood disorder provides only symptomatic relief and is associated with many side effects. Supplementation with vitamin E has been shown to be effective in ameliorating anxiety and depression. However, the effects of vitamin E and its underlying mechanism in ameliorating menopause-associated mood disorders remain uncertain. This work evaluated the effects of α-tocopherol and tocotrienol-rich palm oil extract on depressive and anxiety-related phenotypes induced by estrogen deficiency through ovariectomy in mice. Our study revealed that ovariectomized mice exhibited alterations in behavior indicative of depressive- and anxiety-like behaviors. The serum corticosterone level, a glucocorticoid hormone associated with stress, was found to be elevated in ovariectomized mice as compared to the sham group. Oral administration of α-tocopherol (50 and 100 mg/kg) and tocotrienol-rich palm oil extract (100 and 200 mg/kg) for 14 days alleviated these behavioral changes, as observed in open field, social interaction, and tail suspension tests. However, treatment with tocotrienol-rich palm oil extract, but not α-tocopherol, modulated the depressive- and anxiety-like responses in ovariectomized mice subjected to chronic restraint stress. Both treatments suppressed the elevated serum corticosterone level. Our findings suggested that α-tocopherol and tocotrienol-rich palm oil extract alleviated menopause-associated mood disorder, at least in part, by modulating the hypothalamic-pituitary-adrenal (HPA) axis. The findings of this study can provide a new foundation for the treatment of menopause-associated depressive- and anxiety-like phenotypes, for the betterment of psychological wellbeing.

Urinary symptoms and female sexual dysfunction in women with type 1 diabetes: the role of depression

BACKGROUND

Some reports suggest that women with type 1 diabetes (T1D) have a greater burden of female sexual dysfunction (FSD) than women without T1D, but the etiology of this elevated risk is poorly understood.

AIM

To examine the associations between FSD and urinary incontinence/lower urinary tract symptoms (UI/LUTS) in women with T1D and to evaluate how depression may mediate these relationships.

METHODS

LUTS and UI symptoms were assessed in women with T1D who participated in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study. Multivariable logistic regression models estimated associations between FSD and UI/LUTS (overall and specific domains) and the impact of depression on these associations.

OUTCOMES

FSD was measured with the Female Sexual Function Index-Reduced.

RESULTS

In total, 499 self-reported sexually active women completed validated assessments of sexual and urinary function (mean ± SD age, 47.7 ± 7.6 years; T1D duration, 23.4 ± 5.15 years). FSD was reported in 232 (46%) responders. The frequency of UI and LUTS was 125 (25.1%) and 96 (19.2%), respectively. Neither UI nor its subcategories (urge, stress) were associated with FSD. Although LUTS (odds ratio [OR], 1.75; 95% CI, 1.09-2.77) and its symptoms of urgency (OR, 1.99; 95% CI, 1.09-3.61) and incomplete emptying (OR, 2.44; 95% CI, 1.23-4.85) were associated with FSD, these associations were attenuated following adjustment for depression and antidepressant medication use. Depression indicators were independently associated with FSD overall and across domains.

CLINICAL IMPLICATIONS

The complex interplay of voiding dysfunction, mental health, and sexual function warrants further investigation to understand the potential implications for patient assessment, goal setting, treatment, and care planning.

STRENGTHS AND LIMITATIONS

Data are from a prospective study of individuals with T1D. These results are unable to explore cause-and-effect relationships among LUTS, UI, depression, and FSD. The sample may not be representative of the general population of women with T1D. Because participants in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study are mostly White, generalizing the findings to other races and to type 2 diabetes may not be appropriate. While exclusion of sexually inactive women likely biases our findings toward the null, this design element permitted study of LUTS and UI in relation to aspects of FSD, the primary objective of this study.

CONCLUSIONS

The significant associations between LUTS/UI and FSD among middle-aged women with T1D were greatly attenuated when depression was considered a mediating factor.

Severe mental illness and the perimenopause

Hormonal fluctuations in the perimenopause are associated with an array of physical and psychological symptoms. Those with pre-existing mental disorders may experience changes to their symptoms and response to treatment during the perimenopausal and postmenopausal periods and may also be at risk of poorer longer-term physical health outcomes in menopause. The transition towards menopause may be compounded by the oestradiol-suppressing effect of many psychotropics on the hypothalamopituitary-gonadal axis. A collaborative approach between primary care and secondary mental health services is an opportunity for proactive discussion of symptoms and support with management of the perimenopause. This may involve lifestyle measures and/or hormone replacement therapy, which can both lead to improvements in well-being and mental and physical health.

Abnormal Reginal Homogeneity in Left Anterior Cingulum Cortex and Precentral Gyrus as a Potential Neuroimaging Biomarker for First-Episode Major Depressive Disorder

OBJECTIVE

There is no objective method to diagnose major depressive disorder (MDD). This study explored the neuroimaging biomarkers using the support vector machine (SVM) method for the diagnosis of MDD.

METHODS

52 MDD patients and 45 healthy controls (HCs) were involved in resting-state functional magnetic resonance imaging (rs-fMRI) scanning. Imaging data were analyzed with the regional homogeneity (ReHo) and SVM methods.

RESULTS

Compared with HCs, MDD patients showed increased ReHo in the left anterior cingulum cortex (ACC) and decreased ReHo in the left precentral gyrus (PG). No correlations were detected between the ReHo values and the Hamilton Rating Scale for Depression (HRSD) scores. The SVM results showed a diagnostic accuracy of 98.96% (96/97). Increased ReHo in the left ACC, and decreased ReHo in the left PG were illustrated, along with a sensitivity of 98.07%(51/52) and a specificity of100% (45/45).

CONCLUSION

Our results suggest that abnormal regional neural activity in the left ACC and PG may play a key role in the pathophysiological process of first-episode MDD. Moreover, the combination of ReHo values in the left ACC and precentral gyrusmay serve as a neuroimaging biomarker for first-episode MDD.

Comparative Effectiveness and Tolerability of the Pharmacology of Monoclonal Antibodies Targeting the Calcitonin Gene-Related Peptide and Its Receptor for the Prevention of Chronic Migraine: a Network Meta-analysis of Randomized Controlled Trials

Monoclonal antibodies (mAbs) acting on the calcitonin gene-related peptide (CGRP) or on its receptor are new therapeutic biologics to prevent chronic migraine (CM). Four mAbs acting on the CGRP or on its receptor are new therapeutic biologics to prevent CM. The aim of current network meta-analysis (NMA) was to compare the efficacy and acceptability of CGRP mAbs with onabotulinumtoxinA or topiramate for CM. We included randomized controlled trials (RCTs) examining CGRP mAbs and onabotulinumtoxinA or topiramate in patients with CM. All network meta-analytic procedures were conducted using the frequentist model. The primary outcomes were changes in the monthly migraine days and the 50% response rate. The safety was evaluated with acceptability (i.e., drop-out rate) and rate of any adverse event. This NMA of thirteen RCTs, which, in total, consisted of 5634 participants, demonstrated that a single 300 mg of eptinezumab (mean difference =  - 2.60 days, 95% confidence intervals (95% CIs) =  - 4.43 to - 0.77 compared with placebo) demonstrated the best improvement in monthly migraine days among all interventions. In addition, 675 mg fremanezumab in the first month followed by 225 mg in the second and third months (odds ratio (OR) = 2.96, 95% CIs = 2.20 to 3.97 compared to placebo) was associated with the best response rate among all the interventions. Monthly 140 mg erenumab (MD =  - 2.50 days, 95% CIs =  - 3.83 to - 1.17 compared with placebo) was the best choice for reducing the number of acute migraine-specific medication use days. The safety analysis revealed that loading dose of 240 mg galcanezumab and monthly 240 mg (OR = 0.43, 95% CIs = 0.22 to 0.84) was associated with the lowest drop-out rate; loading dose fremanezumab 675 mg and monthly 675 mg (OR = 1.44, 95% CIs = 1.10 to 1.89), loading dose of 240 mg galcanezumab and monthly 120 mg (OR = 1.37, 95% CIs = 1.02 to 1.84), and single dose of fremanezumab 675 mg (OR = 1.35, 95% CIs = 1.00 to 1.83) were associated with significantly higher rates of AEs than the placebo/control groups. Our NMA indicated that all four CGRP mAbs demonstrated excellent safety, acceptability, and efficacy profiles compared to the traditional prophylaxis for CM. However, because there are several limitations, the findings of the current NMA should be taken into consideration with caution.

Effect of an ashwagandha (Withania Somnifera) root extract on climacteric symptoms in women during perimenopause: A randomized, double-blind, placebo-controlled study

BACKGROUND

Perimenopause is the period during which many physiological changes mark the transition into the final menstrual period of a woman and these changes are associated with climacteric symptoms.

OBJECTIVES

This study aimed to assess the efficacy and tolerability of an Ashwagandha root extract on the climacteric symptoms, quality of life (QoL), and hormonal parameters in perimenopausal women.

MATERIALS AND METHODS

In this 8-week, randomized, double-blind, placebo-controlled study, 100 women with climacteric symptoms were randomly allocated to take either a placebo or 300 mg of an Ashwagandha root extract twice daily. Outcomes were measured using the menopause rating scale (MRS), menopause-specific QoL (MENQoL), hot flash score, and hormonal changes in estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone.

RESULTS

Among 100 participants enrolled, 91 participants completed the study. In comparison with the placebo, ashwagandha supplementation was associated with a statistically significant reduction in total MRS score (p < 0.0001), reflected by significant reductions in the psychological (p = 0.0003), somato-vegetative (p = 0.0152), and urogenital (p < 0.0001) domains. Ashwagandha intake demonstrated a statistically significant reduction in total MENQoL scores (p < 0.0001) and was also associated with a statistically significant increase in serum estradiol (p < 0.0001) and a significant reduction in serum FSH (p < 0.0001) and serum LH (p < 0.05) compared with the placebo. There was no significant between the group differences in the serum testosterone level.

CONCLUSION

These findings suggest that ashwagandha root extract can be a safe and effective option to relieve mild to moderate climacteric symptoms during perimenopause in women.

The Effects of a Saffron Extract (affron®) on Menopausal Symptoms in Women during Perimenopause: A Randomised, Double-Blind, Placebo-Controlled Study

Objectives

There is preliminary evidence suggesting saffron may effectively treat menopausal symptoms. The aim of this study was to examine the tolerability and efficacy of a standardised saffron extract (affron®) on menopausal complaints in perimenopausal women.

Methods

In this 12-week, parallel-group, double-blind, randomised controlled trial, 86 perimenopausal women experiencing menopausal complaints received either a placebo or 14 mg of a saffron extract (affron®), twice daily. Outcome measures included the Greene Climacteric Scale (GCS), Positive and Negative Affect Schedule (PANAS), and Short Form-36 Health Survey (SF-36).

Results

Based on data collected from 82 participants, saffron was associated with greater improvements in mood and psychological symptoms compared to the placebo. Results from the GCS revealed a significantly greater reduction in the GCS psychological score (P = 0.032), characterised by a 33% reduction in anxiety and a 32% reduction in depression scores from baseline to week 12. There was also a significantly greater reduction in the PANAS negative affect score (P = 0.043) compared to the placebo. However, compared to the placebo, saffron was not associated with greater improvements in vasomotor symptoms, somatic symptoms, or other quality of life measures. Saffron intake was well tolerated with no reported major adverse events.

Conclusions

The saffron extract, affron®, administered for 12 weeks at a dose of 14 mg twice daily was associated with greater improvements in psychological symptoms. Further studies in perimenopausal women presenting with varying severity of menopausal symptoms, using different doses of saffron will be useful to examine in future clinical trials.
