Hormones and depression: what are the facts about premenstrual syndrome, menopause, and hormone replacement therapy?

Risk Factors, Prognosis, Influence on the Offspring, and Genetic Architecture of Perinatal Depression Classified Based on the Depressive Symptom Trajectory

This study is aimed at revealing the risk factors, prognosis, influence on offspring, and genetic architecture of perinatal depression (PD) classified based on the depressive symptom trajectory. Pregnant women with no history of major depressive disorder (MDD) were recruited and followed up with their offspring from 1 to 5 years postpartum. Using four self-report questionnaires in the perinatal period, PD was classified into four subtypes: pregnancy, early postpartum, late postpartum, and chronic PD. Risk factors, depressive symptom trajectory from 1 to 5 years postpartum, and child behavior problems were compared among the four PD subtypes. Genome-wide association studies (GWASs) were conducted for each subtype. The relationships between the PD subtypes and polygenic risk scores (PRS) for MDD, a psychiatric disorder, and premenstrual syndrome (PMS), a hormonal disorder, were examined. Among 12,338 participants, 1,145 (9.3%) developed pregnancy PD, 856 (6.9%) developed early postpartum PD, 382 (3.1%) developed late postpartum PD, and 1,048 (8.5%) developed chronic PD. Depressive symptoms decreased to 61.0%-73.3% in the 5 years postpartum. The relationship between risk factors and PD varied based on the PD subtype. Additionally, chronic PD increased the risk of child behavior problems by 2- to 3-fold. The GWASs uncovered five significant variants in different loci depending on PD subtypes, suggesting a subtype-specific genetic architecture. The PRS for MDD was related to pregnancy, early postpartum, and chronic PD, while that for PMS was related to late postpartum PD. It was concluded that PD is heterogeneous depending on the depressive symptom trajectory. Thus, specific prevention and treatment strategies are needed.

Stress and rumination in Premenstrual Syndrome (PMS): Identifying stable and menstrual cycle-related differences in PMS symptom severity

Since the inclusion of Premenstrual Dysphoric Disorder (PMDD) as a mood disorder in the DSM-5, Premenstrual Syndrome (PMS) symptoms have received more attention from researchers and clinicians. In this large-scale study, we investigated core psychological concepts relevant to mood disorder vulnerability between people with 1) no to mild, 2) moderate to severe, and 3) PMDD levels of PMS symptoms. Several trait measures related to mood disorders including depressive symptoms, feelings of stress and anxiety, and ruminative thinking were measured (single measurement, N = 380) along with state (momentary) reports of stress and stress-related perseverative thinking (measured twice, once in the follicular and once in the premenstrual/luteal phase, N = 237). We consistently observed that participants with higher severity of PMS symptoms also scored higher on depression, anxiety, stress, and rumination (trait measures). We also found consistent increases in momentary stress and stress-related perseverative ruminative thinking with increased PMS symptoms at each of our two test moments (in the middle of the follicular and premenstrual/luteal phase respectively). Interestingly, we did not find significant differences between our two test moments for any group, despite PMS being characterized by specific systems in the premenstrual/luteal phase. However, this could be due to noise surrounding the testing moments due to the temporal resolution of the questionnaires and the menstrual cycle estimation method. Nevertheless, these results suggest that stress and rumination are important psychological mechanisms to consider in PMS. Future PMS research studying stress and rumination on a day-to-day basis in combination with hormonal measures is warranted.

Lomens-P0 (mixed extracts of Hordeum vulgare and Chrysanthemum zawadskii) regulate the expression of factors affecting premenstrual syndrome symptoms

BACKGROUND/OBJECTIVES

Premenstrual syndrome (PMS) is a disorder characterized by repeated emotional, behavioral, and physical symptoms before menstruation, and the exact cause and mechanism are uncertain. Hyperprolactinemia interferes with the normal production of estrogen and progesterone, leading to PMS symptoms. Thus, we judged that the inhibition of prolactin hypersecretion could mitigate PMS symptoms.

MATERIALS/METHODS

Hordeum vulgare L. extract (HVE), Chrysanthemum zawadskii var. latilobum extract (CZE), and Lomens-P0 the mixture of these extracts were tested in subsequent experiments. The effect of extracts on prolactin secretion at the in vitro level was measured in GH3 cells. Nitric oxide and pro-inflammatory mediator expression were measured in RAW 264.7 cells to confirm the anti-inflammatory effect. Also, the hyperprolactinemic Institute for Cancer Research (ICR) mice model was used to measure extract effects on prolactin and hormone secretion and uterine inflammation.

RESULTS

Anti-inflammatory effects of and prolactin secretion suppress by HVE and CZE were confirmed through in vitro experiments (P < 0.05). Treatment with Lomens-P0 inhibited prolactin secretion (P < 0.05) and restored normal sex hormone secretion in the hyperprolactinemia mice model. In addition, extracts significantly inhibited the expression of pro-inflammatory biomarkers, including interleukin-1β, and -6, tumor necrosis factor-α, inducible nitric oxide synthase, and cyclooxygenase-2 (P < 0.01). We used high-performance liquid chromatography analyses to identify tricin and chlorogenic acid as the respective components of HVE and CZE that inhibit prolactin secretion. The Lomens-P0, which includes tricin and chlorogenic acid, is expected to be effective in improving PMS symptoms in the human body.

CONCLUSIONS

The Lomens-P0 suppressed the prolactin secretion in hyperprolactinemia mice, normalized the sex hormone imbalance, and significantly suppressed the expression of inflammatory markers in uterine tissue. This study suggests that Lomens-P0 may have the potential to prevent or remedy materials to PMS symptoms.

Comparative safety and efficacy of tibolone and escitalopram in postmenopausal women

BACKGROUND

A high prevalence of psychiatric disorders, particularly depressive and anxiety disorders among women is observed through the postmenopausal stage.

AIM

The aim of this study is to compare the safety and efficacy of tibolone (TIB) and escitalopram (ESCIT) in postmenopausal women (PMW).

MATERIALS AND METHODS

It was an interventional, open-label, hospital-based, follow-up study conducted on 60 PMW with the diagnosis of depression as per the Diagnostic and Statistical Manual of Mental Disorder-5 criteria. Patients were divided into two groups of 30 each, i.e. Group I (TIB-2.5 mg/day) and Group II (ESCIT-10-20 mg/day). The primary outcome was assessed for change in climacteric symptom scores on Greene's Climacteric Scale (GCS), severity of depression and anxiety on Hamilton Rating Scale for Depression (HAM-D) and Hamilton Anxiety Rating Scale (HAM-A), and sexual functioning on Arizona Sexual Experience Scale (ASEX). The secondary outcome of well-being was assessed on World Health Organization Quality of life (QOL)-BREF. All the observations were carried out from baseline and at 2, 4, 8, and 12 weeks.

RESULTS

Both the groups showed significant improvement in climacteric and depressive symptoms. However, at the 8^th and 12^th weeks, mean ± standard deviation scores were significantly lower in Group I (GCS score - 24.80 ± 4.92, 20.30 ± 3.56; HAM-D score - 16.57 ± 5.83, 10.2 ± 5.67) compared to Group II (GCS score - 27.27 ± 5.83 and 23.33 ± 5.70, HAM-D score - 19.97 ± 7.98 and 16.17 ± 10.11). No significant difference between the groups was seen for anxiety on HAM-A scores. Only in Group I, there was significant improvement in ASEX scores. QoL in Group I had shown significant improvement in physical and psychological domain compared to Group II at different time interval, i.e. 4^th and 8^th week onward. In Group I, Alternative Dispute Resolution was reported to be 23.3%, whereas it was 56.7% in Group II. However, none were serious to warrant discontinuation.

CONCLUSION

TIB was better than ESCIT in improving depression, climacteric symptoms, and physical and psychological domain of QoL with an additional benefit of restoring sexual functioning.

Depression, Estrogens, and Neuroinflammation: A Preclinical Review of Ketamine Treatment for Mood Disorders in Women

Ketamine has been shown to acutely and rapidly ameliorate depression symptoms and suicidality. Given that women suffer from major depression at twice the rate of men, it is important to understand how ketamine works in the female brain. This review explores three themes. First, it examines our current understanding of the etiology of depression in women. Second, it examines preclinical research on ketamine's antidepressant effects at a neurobiological level as well as how ovarian hormones present a unique challenge in interpreting these findings. Lastly, the neuroinflammatory hypothesis of depression is highlighted to help better understand how ovarian hormones might interact with ketamine in the female brain.

Differential 28-Days Cyclic Modulation of Affective Intensity in Female and Male Participants via Social Media

The menstrual cycle affects many aspects of female physiology, from the immune system to behavioral and emotional regulation. It is unclear however if these physiological changes are reflected in everyday, naturalistic language production, and moreover whether these putative effects can be consistently quantified. Using a novel approach based on social networks, we characterized linguistic expression differences in female and male volunteers over the course of several months, while having no physiological or reported information of the female participants' menstrual cycles. We used a simple algorithm to quantify the linguistic affect intensity of 418 (184 females and 234 males) subjects using their social networks production and found a 7-day modulatory cycle of affect intensity that corresponds to labor-week fluctuations, with no significant difference by biological sex, and a 28-day cycle over which females are significantly different than males. Our results are consistent with the hypothesis that the menstrual cycle modulates affective features of naturalistic linguistic production.

5-HT1A receptors of the prelimbic cortex mediate the hormonal impact on learned fear expression in high-anxious female rats

Hormones highly influence female behaviors. However, research on this topic has not usually considered the variable hormonal status. The prelimbic cortex (PrL) is commonly engaged in fear learning. Connections from and to this region are known to be critical in regulating anxiety, in which serotonin (5-HT) plays a fundamental role, particularly through changes in 5-HT1A receptors functioning. Also, hormone fluctuations can greatly influence anxiety in humans and anxiety-related behavior in rodents, and this influence involves the functioning of 5-HT brain systems. The present investigation sought to determine whether fluctuations in ovarian hormones relative to the estrous cycle would influence the expression of learned fear in female rats previously selected as low- (LA) or high-anxious (HA). Furthermore, we investigate the role of the 5-HT system of the PrL, particularly the 5-HT1A receptors, as a possible modulator of estrous cycle influence on the expression of learned fear through intra-PrL microinjections of 5-HT itself or the full 5-HT1A agonist 8-OH-DPAT (8-hydroxy-2-(di-n-propylamine)tetralin). Behavioral changes were assessed using the fear-potentiated startle (FPS) procedure. The results showed that fear intensity is associated with hormonal decay, being more accentuated during the estrus phase. This increase in fear levels was found to be negatively correlated with the expression of potentiated startle. In rats prone to anxiety and tested during the proestrus and estrus phases, 5-HT mechanisms of the PrL seem to play a regulatory role in the expression of learned fear. These results were not replicated in the LA rats. Similar but less intense results were found regarding the early and late diestrus. Our data indicate that future studies on this subject need to take into account the dissociation between low- and high-responsive females to understand how hormones affect emotional behavior.

Depressive Disorders Related to Female Reproductive Transitions

Depression is rapidly becoming a major health concern. Recent estimates rank it as the fourth leading cause of disease burden worldwide, and its incidence is steadily increasing. Women have a risk of experiencing depressive illnesses that is twice that of men. Women with depression also typically experience greater functional impairment. The incidence of depression dramatically increases during the reproductive years, which correspond to ages 25 to 44 years. During this time frame, women may experience several reproductive milestones or transitional events such as menarche, the menstrual cycle, pregnancy, infertility, miscarriage, and perimenopause/menopause. These transitions evoke neuroendocrinologic changes that appear to influence the risk for depressive episodes. Common disorders associated with these hormonal fluctuations include premenstrual dysphoric disorder, postpartum depression, and depression in the perimenopausal transition. Although the specific pathophysiologic association is still unclear, evidence supports that these reproductive transitions influence the risk of depression in women.

Progesterone facilitates exploration, affective and social behaviors among wildtype, but not 5α-reductase Type 1 mutant, mice

Progesterone (P4) facilitates exploration, anxiety and social behaviors in estrogen (E2)-primed mice. Some of these effects may be due to actions of its 5α-reduced metabolite, 5α-pregnan-3α-ol-20-one (3α,5α-THP). In order to address the role of P4 and its metabolite, 3α,5α-THP, a mouse model was utilized. We hypothesized that if P4's metabolism to 3α,5α-THP is essential to facilitate exploratory, anti-anxiety and social behaviors of mice, then wildtype, but not 5α-reductase knockout (5α-RKO), mice will have greater expression of these behaviors. Experiment 1: Mice were ovariectomized (ovx), E2-primed and administered P4 (0, 125, 250, or 500μg) subcutaneously and then tested 4h later in a battery of tasks: open field, elevated plus maze, and social interaction. Experiment 2: Ovx, E2-primed mice were administered P4 (4mg/kg), 3α,5α-THP (4mg/kg), medroxyprogesterone acetate (MPA, which does not convert to 3α,5α-THP; 4mg/kg), or vehicle subcutaneously and tested 4h later. There was a dose-dependent effect of P4 to wildtype, but not 5α-RKO, mice. Neither wildtype, nor 5α-RKO, mice had increased exploration, anti-anxiety or pro-social behavior with MPA administration. Progesterone only exerted effects on anti-anxiety behavior, and increased 3α,5α-THP in the prefrontal cortex and hippocampus, when administered to wildtype mice. 3α,5α-THP to both WT and 5α-RKO mice increased exploration, anti-anxiety and social interaction and 3α,5α-THP levels in the hippocampus and prefrontal cortex. Thus, metabolism of P4 by the 5α-reductase enzyme may be essential for enhancement of these behaviors.

Oestradiol modulation of serotonin reuptake transporter and serotonin metabolism in the brain of monkeys

Serotonin (5-hydroxytryptamine; 5-HT) is an important brain neurotransmitter that is implicated in mental and neurodegenerative diseases and is modulated by ovarian hormones. Nevertheless, the effect of oestrogens on 5-HT neurotransmission in the primate caudate nucleus, putamen and nucleus accumbens, which are major components of the basal ganglia, and the anterior cerebral cortex, mainly the frontal and cingulate gyrus, is not well documented. The present study evaluated 5-HT reuptake transporter (SERT) and 5-HT metabolism in these brain regions in response to 1-month treatment with 17β-oestradiol in short-term (1 month) ovariectomised (OVX) monkeys (Macaca fascicularis). SERT-specific binding was measured by autoradiography using the radioligand [³H]citalopram. Biogenic amine concentrations were quantified by high-performance liquid chromatography. 17β-Oestradiol increased SERT in the superior frontal cortex and in the anterior cingulate cortex, in the nucleus accumbens, and in subregions of the caudate nucleus of OVX monkeys. 17β-Oestradiol left [³H]citalopram-specific binding unchanged in the putamen, as well as the dorsal and medial raphe nucleus. 17β-Oestradiol treatment decreased striatal concentrations of the precursor of 5-HT, 5-hydroxytryptophan, and increased 5-HT, dopamine and 3-methoxytyramine concentrations in the nucleus accumbens, caudate nucleus and putamen, whereas the concentrations of the metabolites 5-hydroxyindoleacetic acid, 3,4-dihydroxyphenylacetic acid and homovanillic acid remained unchanged. No effect of 17β-oestradiol treatment was observed for biogenic amine concentrations in the cortical regions. A significant positive correlation was observed between [³H]citalopram-specific binding and 5-HT concentrations in the caudate nucleus, putamen and nucleus accumbens, suggesting their link. These results have translational value for women with low oestrogen, such as those in surgical menopause or perimenopause.

Menstrual cycle phase modulates emotional conflict processing in women with and without premenstrual syndrome (PMS)--a pilot study

Background

Premenstrual syndrome (PMS) is characterized by a cluster of psychological and somatic symptoms during the late luteal phase of the menstrual cycle that disappear after the onset of menses. Behavioral differences in emotional and cognitive processing have been reported in women with PMS, and it is of particular interest whether PMS affects the parallel execution of emotional and cognitive processing. Related to this is the question of how the performance of women with PMS relates to stress levels compared to women without PMS. Cortisol has been shown to affect emotional processing in general and it has also been shown that women with severe PMS have a particular cortisol profile.

Methods

We measured performance in an emotional conflict task and stress levels in women with PMS (n = 15) and women without PMS (n = 15) throughout their menstrual cycle.

Results

We found a significant increase (p = 0.001) in the mean reaction time for resolving emotional conflict from the follicular to the luteal cycle phase in all subjects. Only women with PMS demonstrated an increase in physiological and subjective stress measures during the luteal menstrual cycle phase.

Conclusions

Our findings suggest that the menstrual cycle modulates the integration of emotional and cognitive processing in all women. Preliminary data are supportive of the secondary hypothesis that stress levels are mediated by the menstrual cycle phase only in women with PMS. The presented evidence for menstrual cycle-specific differences in integrating emotional and cognitive information highlights the importance of controlling for menstrual cycle phase in studies that aim to elucidate the interplay of emotion and cognition.

Comparison of the effects of estradiol and progesterone on serotonergic function

BACKGROUND

Ovarian hormones may contribute to the vulnerability to depression, as well as to the response to antidepressants (ADs). Previously, we reported that acute systemic treatment with estradiol or progesterone blocked the ability of the selective serotonin reuptake inhibitor, fluvoxamine, to inhibit serotonin transporter function in ovariectomized rats. In this study, behavioral consequences, as well as receptor mechanisms underlying these hormonal effects, were investigated.

METHODS

Using the forced swimming test, the acute effect of estradiol and/or progesterone on fluvoxamine's AD-like effects was investigated. Using in vivo chronoamperometry, the effect of local application of estradiol or progesterone into the hippocampus of ovariectomized rats on serotonin (5-HT) clearance, as well as on the ability of fluvoxamine to slow 5-HT clearance, were investigated.

RESULTS

The decreased immobility and increased swimming caused by fluvoxamine in the forced swimming test was blocked in rats treated with estradiol and/or progesterone. Local application of estradiol, but not progesterone, slowed 5-HT clearance and both hormones blocked the ability of fluvoxamine to slow 5-HT clearance. Use of hormone receptor agonists and antagonists, revealed that the effects of estradiol are mediated by activation of membrane, as well as nuclear estrogen receptors (ER). The AD-like effect of estradiol involved ER beta and G-protein coupled receptor 30, whereas its blockade of fluvoxamine's effects was ER alpha-mediated. The effects of progesterone occurred solely by activation of intracellular progesterone receptors.

CONCLUSIONS

Targeting of ER beta or G-protein coupled receptor 30 might reveal a strategy to permit beneficial effects of estrogen without its deleterious effect on selective serotonin reuptake inhibitor efficacy.

Reliability and component structure of the modified Daily Symptom Report (DSR-20)

OBJECTIVES

The purpose of the present study was to modify Freeman et al.'s (1996) Daily Symptom Report (DSR) for premenstrual syndrome (PMS) by adding items depicting aggressive and impulsive symptoms, to explore the component structure of this revised measure (DSR-20) in a sample of PMS sufferers, and to compare their scores with those from controls during the follicular and luteal cycle phases.

METHODS

The DSR-20 was administered to 140 PMS sufferers who were seeking treatment for PMS and 54 controls who considered themselves to be free from premenstrual complaints daily for three menstrual cycles.

RESULTS

Cronbach's α was 0.95 for the luteal DSR-20 scores of the PMS sufferers, indicating very high internal consistency of the 20 items. Exploratory Principal Components Analysis (PCA) of the luteal ratings of the PMS sufferers identified two components with high internal consistency (>0.90), describing psychological and physical premenstrual symptoms. PMS sufferers scored significantly higher than the controls on each of these components during the luteal, but not follicular, phase.

CONCLUSIONS

The DSR-20 total scale score is an internally consistent global measure of the intensity of PMS. The division of PMS symptoms into psychological and physical components, both of which significantly differentiated PMS sufferers from controls during the luteal phase, sheds further light on the description of PMS and provides a clinically relevant and practical means by which to summarise and interpret daily symptom ratings, necessary for the identification and investigation of the syndrome.

The efficacy of Hypericum perforatum (St John's wort) for the treatment of premenstrual syndrome: a randomized, double-blind, placebo-controlled trial

BACKGROUND

Premenstrual syndrome (PMS) is a common condition. Some of the most widely prescribed medications are selective serotonin reuptake inhibitors (SSRIs), based on the hypothesized role of serotonin in the production of PMS symptoms. PMS sufferers, especially those experiencing mild to moderate symptoms, are often reluctant to take this form of medication and instead buy over-the-counter preparations to treat their symptoms, for which the evidence base with regard to efficacy is limited. Hypericum perforatum (St John's wort) influences the serotonergic system. As such, this widely available herbal remedy deserves attention as a PMS treatment.

OBJECTIVE

To investigate the effectiveness of Hypericum perforatum on symptoms of PMS.

STUDY DESIGN

This randomized, double-blind, placebo-controlled, crossover study was conducted between November 2005 and June 2007.

SETTING

Institute of Psychological Sciences, University of Leeds, Leeds, UK.

PARTICIPATION

36 women aged 18-45 years with regular menstrual cycles (25-35 days), who were prospectively diagnosed with mild PMS.

INTERVENTION

Women who remained eligible after three screening cycles (n = 36) underwent a two-cycle placebo run-in phase. They were then randomly assigned to receive Hypericum perforatum tablets 900 mg/day (standardized to 0.18% hypericin; 3.38% hyperforin) or identical placebo tablets for two menstrual cycles. After a placebo-treated washout cycle, the women crossed over to receive placebo or Hypericum perforatum for two additional cycles.

MAIN OUTCOME MEASURES

Symptoms were rated daily throughout the trial using the Daily Symptom Report. Secondary outcome measures were the State Anxiety Inventory, Beck Depression Inventory, Aggression Questionnaire and Barratt Impulsiveness Scale. Plasma hormone (follicle-stimulating hormone [FSH], luteinizing hormone [LH], estradiol, progesterone, prolactin and testosterone) and cytokine (interleukin [IL]-1beta, IL-6, IL-8, interferon [IFN]-gamma and tumour necrosis factor [TNF]-alpha) levels were measured in the follicular and luteal phases during Hypericum perforatum and placebo treatment.

RESULTS

Hypericum perforatum was statistically superior to placebo in improving physical and behavioural symptoms of PMS (p < 0.05). There were no significant effects of Hypericum perforatum compared with placebo treatment for mood- and pain-related PMS symptoms (p > 0.05). Plasma hormone (FSH, LH, estradiol, progesterone, prolactin and testosterone) and cytokine (IL-1beta, IL-6, IL-8, IFNgamma and TNFalpha) levels, and weekly reports of anxiety, depression, aggression and impulsivity, also did not differ significantly during the Hypericum perforatum and placebo cycles (p > 0.05).

CONCLUSION

Daily treatment with Hypericum perforatum was more effective than placebo treatment for the most common physical and behavioural symptoms associated with PMS. As proinflammatory cytokine levels did not differ significantly between Hypericum perforatum and placebo treatment, these beneficial effects are unlikely to be produced through this mechanism of action alone. Further work is needed to determine whether pain- and mood-related PMS symptoms benefit from longer treatment duration.

Neurosteroids' effects and mechanisms for social, cognitive, emotional, and physical functions

Hormones are trophic factors that integrate central and peripheral nervous system functions, and can influence social, cognitive, emotional and physical (SCEP) processes. Greater understanding of behavioral and neurobiological underpinnings of mental, cognitive, and/or physical changes with maturation is becoming increasingly important as the world's population ages. There are individual differences in how people age, but the factors that influence these differences are not well understood. Social supports are one factor that may influence the trajectory of age-related processes. The loss of close relationships, especially among older persons, is one of the greatest risk factors for mental and physical decline. Progesterone, secreted by the ovaries, or produced de novo in the brain, is readily converted centrally to 5alpha-pregnan-3alpha-ol-20-one (3alpha,5alpha-THP), and can influence SCEP, through rapid, non-classical steroid-mediated actions. Our hypothesis is that 3alpha,5alpha-THP is a key trophic factor in SCEP and development. Our research has demonstrated that 3alpha,5alpha-THP facilitates social and sexual behavior of rodents, which evokes further increases in 3alpha,5alpha-THP in midbrain and hippocampus, brain areas involved in SCEP. The role of 3alpha,5alpha-THP to influence social and/or sexual experience, and thereby SCEP, is discussed in this review. Further understanding of these neurobiological and/or behavioral factors may lead to findings that ultimately can promote health and prevent disease.

Depressed mood through women's reproductive cycle: correlation to mood at menopause

OBJECTIVES

Depressive symptoms are frequent through the different stages of a woman's reproductive cycle. The aim of this study was to evaluate a possible correlation of depressive mood before menstruation, during pregnancy, after delivery and around the menopause.

METHODS

The sample consisted of 110 women (mean age 52 years, standard deviation 4 years) who rated their mood at present and retrospectively at different stages of the reproductive cycle. Mood was rated using a visual analogue scale.

RESULTS

A significant statistical association was found between the present mood and mood at the premenstrual period, but not with mood at pregnancy or after delivery. These findings were independent of age, menopausal status or use of hormone replacement therapy.

CONCLUSIONS

The statistical association between depressed mood around menopause and before menstruation supports the assumption that there is a common etiology, which could be attributed to hormonal or psychological factors, or both.

Associations between maternal older age, family environment and parent and child wellbeing in families using assisted reproductive techniques to conceive

Maternal age effects on parenting and family outcomes are of increasing interest because of the demographic shift toward older maternal age at first birth. Maternal age is also of interest because of the greater use of assisted reproductive techniques (ART) to bypass age-related infertility in couples trying to conceive late in the reproductive life cycle of the woman. The aim of the present study was to investigate maternal age effects associated with delayed parenting by comparing families of mothers who gave birth at a younger (<31 years) or older (>38 years) age and to ascertain whether associations were linear associations by comparing these groups to women who had conceived in between these ages (i.e., >31 and <38 years). All children (4-11 year olds) were first-born and conceived using ART. Participants were recruited from one of 20 fertility clinics and mothers (n=642) and fathers (n=439) completed a postal questionnaire about demographic and reproductive characteristics, family environment as well as parent and child wellbeing. Our results demonstrate that parenthood via assisted conception later in the reproductive life cycle is not associated with a negative impact on child wellbeing. Despite maternal age-group differences on demographic (education, income) and reproductive characteristics (bleeding during pregnancy, caesarean rate, breast feeding), and parental warmth and depressive symptoms, child wellbeing was similar across mother age groups. We conclude that the parenting context is different for older mother families (more depressive symptoms in mothers and fathers, less expressed warmth in the couple) but that this difference is not associated with child wellbeing in early and middle childhood.

Impact of ovarian hormones on the modulation of the serotonin transporter by fluvoxamine

Most preclinical studies examining the mechanism(s) of action of antidepressants are carried out using male animals. Blockade of serotonin transporter (SERT) function by selective serotonin reuptake inhibitors (SSRIs) is the initial event that triggers a not completely understood process that results in clinical improvement in depression. To investigate whether there are differences in the ability of SSRIs to inhibit the SERT between male and female rats at different phases of the estrous cycle, clearance of locally applied serotonin (5-HT) was measured by in vivo chronoamperometry. Local application of the SSRI, fluvoxamine, directly into the CA3 area of hippocampus increased significantly 5-HT clearance time parameters in male rats and female rats in estrus or diestrus, but not in proestrus. The contribution of ovarian steroids to this result was investigated in ovariectomized (OVX) rats treated with estradiol benzoate (EB) and/or progesterone (P). In OVX-control rats, fluvoxamine increased clearance time parameters, whereas EB and/or P treatment blocked this effect, consistent with what was seen in female rats in proestrus. This effect was gender-specific, since treatment of castrated rats with EB/P had no effect on the ability of fluvoxamine to slow 5-HT clearance. The time course of hormonal effects showed that 1-60 min after local application of 17-beta-estradiol (E(2)) into the CA3 region of OVX rats, fluvoxamine had no effect on clearance time of 5-HT. E(2)-BSA mimicked E(2)'s effects at 10 min but not at 60 min. Pretreatment with estrogen receptor antagonists blocked the effects of E(2). The finding that acutely both estradiol and progesterone can inhibit the ability of an SSRI to slow the clearance of 5-HT, may have important implications for the use of SSRIs in women.

Hormonal influences on seizures: basic neurobiology

There are sex differences and effects of steroid hormones, such as androgens, estrogens, and progestogens, that influence seizures. Androgens exert early organizational and later activational effects that can amplify sex/gender differences in the expression of some seizure disorders. Female-typical sex steroids, such as estrogen (E2) and progestins, can exert acute activational effects to reduce convulsive seizures and these effects are mediated in part by the actions of steroids in the hippocampus. Some of these anticonvulsive effects of sex steroids are related to their formation of ligands which have agonist-like actions at gamma-aminobutyric acid (GABAA) receptors or antagonist actions at glutamatergic receptors. Differences in stress, developmental phase, reproductive status, endocrine status, and treatments, such as anti-epileptic drugs (AEDs), may alter levels of these ligands and/or the function of target sites, which may mitigate differences in sensitivity to, and/or tolerance of, steroids among some individuals. The evidence implicating sex steroids in differences associated with hormonal, reproductive, developmental, stress, seizure type, and/or therapeutics are discussed.

Levetiracetam for treatment of premenstrual dysphoric disorder: a pilot, open-label study

Kindling and impaired electroencephalophysiology have been suggested to play a role in the pathophysiology of premenstrual dysphoric disorder (PMDD). Levetiracetam is a novel antiepileptic drug which has shown strong anti-kindling activity in animal models of epilepsy. In this preliminary prospective study we examined the safety and efficacy of levetiracetam for the treatment of PMDD. One hundred twenty-three potential patients were prospectively screened to enroll seven patients into the open-label treatment phase of the study. PMDD was diagnosed per DSM-IV-TR criteria and two consecutive months of prospective ratings of Daily Record of Severity of Problems (DRSP). The Mini International Neuropsychiatric Interview (MINI) was used to exclude any co-morbid conditions. Levetiracetam was started at 250 mg qhs at the end of the first week of the follicular phase. Dosage was gradually increased up to 1,500 mg bid as tolerated or clinically effective. The treatment phase lasted 4 months. Response to treatment was evaluated by Clinical Global Impression (CGI) and DRSP scores. Six out of seven patients experienced a considerable decrease in their DRSP scores with levetiracetam, starting from the first treatment cycle. One patient dropped out of the study due to lack of efficacy after one cycle. Medication was fairly well tolerated. Improvements in food cravings and premenstrual headaches were also noted as unexpected benefits. Anticonvulsant medications, specifically levetiracetam, could be effective in the treatment of PMDD. Future double-blind, placebo controlled, randomized studies are warranted and should include larger number of patients.

Antidepressant effect and changes of GABAA receptor gamma2 subunit mRNA after hippocampal administration of allopregnanolone in rats

The present study aimed to verify the effect of bilateral intra-hippocampus administration of the neurosteroid allopregnanolone (3alpha-hydroxy-5alpha-pregnan-20-one; 3alpha, 5alpha-THP) in the forced swimming test (FST) and in the alpha4 and gamma2 GABA(A) receptor subunits gene expression. Results showed that bilateral intra-hippocampal allopregnanolone administration of 2.5 microg/rat ( P<0.05) reduced immobile behavior and increased climbing behavior in the FST. Overall, for all doses of allopregnanolone tested (1.25, 2.5, 5.0 microg/rat), an increase of gamma2 (P<0.05) GABA(A) subunit mRNA was observed. There was a higher increase in the gamma2 gene expression in the right hemisphere than in the left hemisphere (P<0.01) after allopregnanolone treatment. Intra-hippocampal allopregnanolone did not change the expression of the alpha4 subunits. In conclusion, intra-hippocampal administration of allopregnanolone produces an antidepressant-like effect in the FST at an intermediate dose, confirming the potential of neurosteroids as a new class of antidepressant drugs. Our findings suggest that the gamma2, but not the alpha4 GABA(A) subunit, needs further evaluation to be involved in the antidepressant effect of allopregnanolone in the hippocampus and that there is a hemispheric diversity in the biochemical effect of the drug.

Depression and anxiety through the climacteric period: an epidemiological study (HUNT-II)

AIM

The aim of this study was to examine the prevalence of anxious and depressive symptoms related to menstruational status in a large community sample.

METHOD

In the HUNT-II study all adults in Nord-Trøndelag County of Norway were asked about demographic factors, lifestyle, physical symptoms and somatic diseases, a total of 94,197 persons. Anxious and depressive symptoms were recorded by the Hospital Anxiety and Depression Scale (HADS). Of female persons invited aged 35-60 years (N = 19,677), 16,080 (82%) took part. The menstruation status were defined as pre-, peri- and postmenopausal periods, calculated as the time period from last menstruation to examination date.

RESULTS

There was a significantly higher score on depression and anxiety in the peri- and the postmenopausal period compared to the premenopausal period. Comparing the postmenopausal period with the perimenopausal period, the score for depressive symptoms was somewhat higher while the score for anxious symptoms was somewhat lower. These differences did not reach significance.

CONCLUSION

There was a general effect of age on the scores on HADS-D. For scores on HADS-A there was a peak in the score in the perimenopausal period, indicating a high degree of anxiety symptoms in this time period which is especially connected to fluctuations in the serum level of gonadal hormones.

Major depression after breast cancer: a review of epidemiology and treatment

OBJECTIVE

While many breast cancer patients experience "normal" distress, there is a subset who experience clinically significant depression. We examined the current knowledge about the prevalence, impact and treatment of major depression in women with breast cancer.

METHOD

We reviewed the evidence for the prevalence of depression in women with breast cancer from the last 20 years and summarized the medical literature on the pharmacology and psychotherapy of depression in this population.

RESULTS

Despite evidence that depression significantly impacts quality of life in breast cancer patients, few studies focus on the epidemiology and treatment of major depression. Treatment studies have focused on distress and mixed depressive states, with resulting lack of replicable studies showing treatment efficacy. Potential biological and psychosocial determinants of major depression following breast cancer are discussed in a proposed model. The need for further research on the epidemiology and treatment of major depression in this population is proposed.

CONCLUSION

Major depression is a frequent but underrecognized and undertreated condition among breast cancer patients, which causes amplification of physical symptoms, increased functional impairment and poor treatment adherence. More research on the epidemiology and treatment of major depression in this population is needed.

Quality of life and psychological symptoms in Greek postmenopausal women: association with hormone therapy

Quality of life (QoL) in menopause is influenced by many parameters, including vasomotor symptoms, psychological status and culture. The aim of the present study was to examine the association of hormone therapy (HT) with QoL and psychological symptoms in Greek postmenopausal women. The study assessed 216 postmenopausal women (mean age 54.5 years) attending a university menopause clinic in Greece. Fifty-three were users of HT and 163 were not. QoL was evaluated by the Utian Quality of Life Scale (UQOL) and psychological symptoms were assessed by the Symptom Checklist-90-R (SCL-90-R). Women on HT were younger and more educated than women not using HT. Adjusting the analysis for the women's characteristics, HT users had better total UQOL scores than non-users (p < 0.05). Marital status and education had independent effects on QoL, with married and more educated women scoring higher (p < 0.05). Assessment of psychological symptomatology, after adjustment for sociodemographic variables across the different dimensions, revealed that HT users had better SCL-90-R scores than non-users for obsessionality, interpersonal sensitivity and for the general index (p < 0.05). Concluding, even though the impact of sociodemographic and lifestyle variables must be factored into the assessment of QoL, HT use is independently related to an improvement in the total score and in most domains of QoL, and has a significant positive effect on many aspects of psychological well-being in Greek postmenopausal women.

Estrus variation in anxiolytic-like effects of intra-lateral septal infusions of the neuropeptide Y in Wistar rats in two animal models of anxiety-like behavior

Anxiolytic-like effects of intra-lateral septal infusions of the neuropeptide Y (NPY) were assessed during several estrus phases in Wistar rats tested in two animal models of anxiety-like behavior. In a conflict operant test, results showed that during late proestrus, intra-lateral septal nuclei infusions of NPY (1.0 microg/microl, P<0.05; 2.0 microg/microl, P<0.05; 2.5 microg/microl, P<0.05) increased the number of immediately punished responses. During metestrus-diestrus only the highest doses of NPY (2.5 microg/microl, P<0.05) increased the number of immediately punished reinforcers. In the elevated plus-maze test, results showed that during late proestrus, intra-lateral septal nuclei infusions of NPY (1.0 microg/microl, P<0.05; 2.0 microg/microl, P<0.05) produced anxiolytic-like actions. During metestrus-diestrus only the highest doses of NPY (2.0 microg/microl, P<0.05) produced anxiolytic-like actions. Neither NPY nor estrus phases significantly modified the number of closed arms entries in the elevated plus-maze test. It is concluded that anxiolytic-like effects of NPY vary within the estrus cycle in Wistar rats.

A five-day gradual reduction regimen of chlormadinone reduces premenstrual anxiety and depression: a pilot study

BACKGROUND

Anxiety and depression commonly occur in premenstrual dysphoric disorder (PMDD). The PMDD symptomatology disappears once the menstrual cycle reinitiates, resembling a withdrawal syndrome.

METHODS

The present study is a pilot, controlled, double-blind study exploring the effectiveness of a premenstrual 5-day gradual reduction regimen of chlormadinone acetate on PMDD. Volunteers received an initial dose of 10 mg (five 2-mg tablets) on the 24(th) day of the menstrual cycle and one-fifth of the dose less (one tablet) each day until a dose of 2 mg (one 2-mg tablet) was reached on the 28(th) day of the menstrual cycle. The control group received placebo with a similar regimen.

RESULTS

The 5-day gradual reduction regimen of chlormadinone significantly improved (F(3.76) = 3.29, p <0.02) the daily symptoms report (DSR) scores by the third month of treatment. The resulting relative risk was 4.09 (confidence interval: 1.15-14.57, p <0.005, 95% CI). Compared to placebo, chlormadinone clinically and statistically reduced the severity of depression, anxiety, food cravings, mood swings and cramps. A statistical reduction of symptoms such as poor coordination, irritability, feeling out of control, hopelessness, decreased interest and headache was detected but was not clinically relevant. No changes occurred in concentration difficulties, tiredness, insomnia, swelling, breast tenderness and aches. As side effects, 30% of the volunteers showed changes in the length of the menstrual cycle, and 15% experienced dyspepsia.

CONCLUSIONS

A 5-day gradual reduction regimen of chlormadinone improves some of the discomforting ailments associated with PMDD, namely, depression and anxiety.

Depression in children and adolescents: does gender make a difference?

The occurrence of depression is higher in females after puberty, suggesting a gender-related difference. This article reviews studies that have examined gender differences in the presentation and treatment of depression in adults and discusses how this information applies to depressed children and adolescents. The adult literature suggests that men and women vary in presentation of depression. In addition, differences exist in the pharmacokinetic properties of various medications, but it is unclear how they affect clinical treatment response. Studies of gender differences in child and adolescent depression are limited. Some studies suggest that differences seen in adults may also apply to children and adolescents. Studies of gender differences in treatment response are not available, however. Further study and evidence-based exploration are required to better understand gender differences in depression in children and adolescents.

Anxiolytic effect of estradiol in the median raphe nucleus mediated by 5-HT1A receptors

Estrogen deficiency has been associated with stress, anxiety and depression. Estrogen receptors have been identified in the median raphe nucleus (MRN). This structure is the main source of serotonergic projections to the hippocampus, a forebrain area implicated in the regulation of defensive responses and in the resistance to chronic stress. There is evidence showing that estrogen modulates 5-HT1A receptor functions. In the MRN, somatodendritic 5-HT1A receptors control the activity of serotonergic neurones by negative feedback. The present study evaluated the effect of intra-MRN injection of estradiol benzoate (EB) (600 or 1200ng/0.2microl) on the performance of ovariectomised rats submitted to the elevated plus-maze test of anxiety and to the open-field test. Additionally, the same effect was evaluated with a previous intra-MRN injection of WAY 100635(100ng/0.2microl), an antagonist of 5-HT1A receptors. The results showed that both doses of EB increased the percentage of entries and the percentage of time spent into the open arms, suggestive of an anxiolytic effect. The highest dose of the drug also increased the number of entries into the enclosed arm and locomotion in the open field, indicating a stimulatory motor effect. WAY 100635 antagonised the effect of estradiol in the elevated plus-maze and in the open-field. The results show that estrogen receptors of the MRN are implicated in the regulation of anxiety-related behaviour. The results also support claims that the effect of estrogen involves a change in 5-HT1A receptor function.

Antidepressant-like actions of intra-accumbens infusions of allopregnanolone in ovariectomized Wistar rats

This study was aimed to verify the role of the nucleus accumbens (NAcc) in the antidepressant-like effects of allopregnanolone in ovariectomized rats forced to swim. The interaction between infusions of allopregnanolone (intra-NAcc) with systemic administrations of allopregnanolone, muscimol, fluoxetine and GABA-A antagonists was assessed. Results showed that allopregnanolone (intra-NAcc; 1.5 microg, p < 0.05; 2.0 microg, p < 0.05) or systemic injections of allopregnanolone (1.5 mg/kg, p < 0.05; 2.0 mg/kg, p < 0.05; s.c.) or muscimol (0.3 mg/kg, p < 0.05; 0.6 mg/kg, p < 0.05; i.p.) reduced immobility by increasing climbing in the forced swimming task (FST), whereas fluoxetine (1.0 mg/kg, p < 0.05; 2.0 mg/kg, p < 0.05; i.p.) reduced immobility by increasing swimming. Allopregnanolone (intra-NAcc; 0.5 microg/side) synergized with systemic doses of allopregnanolone (0.5 mg/kg; p < 0.05), muscimol (0.1 mg/kg; p < 0.05) or fluoxetine (0.5 mg/kg; p < 0.05) and reduced immobility by increasing climbing. Picrotoxin (0.125 mg/kg; i.p.) attenuated the synergism of the combination allopregnanolone (intra-NAcc; 0.5 microg/side) plus fluoxetine (i.p.) or allopregnanolone (s.c.) and the effects of allopregnanolone (intra-NAcc; 1.5 microg/side). Bicuculline (2.0 mg/kg; i.p.) attenuated the synergism between the combination allopregnanolone (intra-NAcc; 0.5 microg/side) plus muscimol (i.p.), but not the synergism of the combination allopregnanolone (intra-NAcc; 0.5 microg/side) plus allopregnanolone (s.c.). In conclusion, allopregnanolone (systemic injections or intra-NAcc), fluoxetine or muscimol produced antidepressant-like effects in the FST. Subthreshold doses of allopregnanolone (intra-NAcc) synergized with systemic subthreshold doses of fluoxetine, muscimol or allopregnanolone. Antagonists of the GABA-A receptor canceled the synergism.

A comparison of the central effects of different progestins used in hormone replacement therapy

OBJECTIVE

To evaluate the central effect exerted by different progestins used for hormone replacement therapy.

METHODS

Randomised, placebo-controlled study. One hundred-twenty postmenopausal women on continuous hormonal replacement therapy with transdermal estradiol (50 microg per day) associated, for 10 days every 28 days, with four different progestins: dydrogesterone (DYD; 10 mg per day; n = 20), medroxyprogesterone acetete (MPA; 10 mg per day; n = 20), nomegestrol acetate (NMG; 5 mg per day; n = 20) or norethisterone acetate (NETA; 10 mg per day; n = 20). Other 40 women, 10 for each treatment group, were used as controls and were monitored for a single cycle of 28 days during the administration of transdermal estradiol plus placebo. Morning basal body temperature (BBT) was monitored for 28 days. Anxiety, by the state-trait anxiety inventory, and depression, by the self-evaluation depression scale of Zung, were evaluated just prior to and in the last 2 days of the 10-day progestins adjunct.

RESULTS

All progestins except DYD increased (P < 0.0001) BBT by 0.3-0.5 degrees C. Anxiety was decreased by DYD (- 2.3 + 1.1; P < 0.01) and MPA (- 1.5 + 0.5; P < 0.01), but not by NMG or NETA. Depression did not significantly increase during progestins and actually decreased during MPA (- 3.0 + 0.7; P < 0.01). Only the effect of DYD on anxiety and that of MPA on depression were significant versus the control group (P < 0.05 ).

CONCLUSIONS

Different progestins exert different central effects. DYD has the peculiarity of not increasing BBT and of decreasing anxiety, which is also decreased by MPA. Depression is not negatively affected by the tested progestins and it may be ameliorated by MPA. The present data may help to individualise the progestin choice of hormone replacement therapy.

Synergistic interaction between ketoconazole and several antidepressant drugs with allopregnanolone treatments in ovariectomized Wistar rats forced to swim

This article was aimed to investigate the interest of the combination allopregnanolone plus ketoconazole in depression with the time-sampling method in the forced swimming task. Dose-response curves for fluoxetine (0.5, 1.0 or 2.0 mg/kg, twice day, during 2 weeks; i.p.), desipramine (0.5, 1.0 or 2.14 mg/kg, twice a day, during 2 weeks; i.p.), ketoconazole (6.25, 12.5, 25.0 and 37.5 mg/kg, once a day, during 2 weeks; i.p.) and allopregnanolone (0.5, 1.5, 2.0 mg/kg; once a day, during 2 weeks; s.c.) were established. Fluoxetine (1.0 mg/kg, p < 0.05; 2.0 mg/kg, p < 0.05) or ketoconazole (25.0 mg/kg, p < 0.05; 37.5 mg/kg, p < 0.05) produced antidepressant-like behavioral changes in swimming, highlighting a serotonergic mechanism while desipramine (1.0 mg/kg, p < 0.05; 2.14 mg/kg, p < 0.05) or allopregnanolone (1.5 mg/kg, p < 0.05; 2.0 mg/kg, p < 0.05) increased climbing behavior highlighting noradrenergic or dopaminergic effects. Subthreshold doses of fluoxetine (p < 0.05), desipramine (p < 0.05) or ketoconazole (p < 0.05) synergized with subthreshold doses of allopregnanolone and reduced immobility by increasing climbing. In conclusion, fluoxetine, desipramine, ketoconazole and allopregnanolone produced differential antidepressant-like actions in ovariectomized rats forced to swim. Ketoconazole, fluoxetine or desipramine synergized with allopregnanolone.

Evaluation of depressive conditions among Japanese patients at a menopause clinic

AIM

To examine current depressive tendencies among Japanese patients visiting a menopause clinic with complaints of climacteric symptoms.

METHODS

The subjects were 389 Japanese women (age range: 45-60 years; mean: 51.4 +/- 3.8 years) who visited the menopause clinic in Department of Obstetrics and Gynecology, Keio university hospital, reporting climacteric symptoms. Their depressive tendencies were examined with the SDS (Self-rating Depression Scale, filled out by the patient).

RESULTS

The SDS was computed to be 42.4 +/- 9.9. Ninety-three (23.9%) suffered from an intermediate or higher level depressive tendency; 132 (33.9%) had a mild depression; and 164 (42.2%) were free of any depressive tendency. It was concluded that more than one-half of the subjects suffered from some form of depression. Correlations between age, time after menopause/oophorectomy, and depressive tendency were ambiguous. In comparing the total scores of SDS for pre-, peri-, and postmenopause groups, the incidence of probable depression was higher in the second group, but no significant differences were noted among each group. When the parameters were compared in relation to their hormonal environments, the natural menopause group rated significantly higher in the scores related to sleep disturbance, hopelessness and dissatisfaction than the premenopause group. The number of those who probably exhibited mild or more exaggerated depression was significantly lower in the surgical menopause group in comparison with the natural menopause group.

CONCLUSION

A depressive tendency occurred frequently among Japanese patients with menopausal disorders. It is important to evaluate the mental status of these patients with the aid of an appropriate tool.

Moods in everyday situations: effects of menstrual cycle, work, and personality

OBJECTIVE

This study examined women's moods on work and off days during different phases of the menstrual cycle.

METHOD

Self-reports of the moods angry, happy, sad, stressed, tired, and anxious were obtained on two work and two off days during the luteal and follicular phases of the menstrual cycle in 203 nurses. Individual differences in anger expression, anxiety, and hostility were assessed.

RESULTS

Ratings of anxious, stressed, and tired were higher and happy and sad were lower on the workday than the off day. Menstrual cycle phase was associated with mood differences depending on the day (work, off work) and individual differences in personality traits.

CONCLUSIONS

The experience of moods in everyday life is affected by overall levels of stress and phase of the menstrual cycle. The findings suggest the need to refine sociopsychobiological and clinical models of mood regulation and of risk for disease.

Anticon?ict actions of aqueous extracts of flowers ofAchillea millefolium L. vary according to the estrous cycle phases in Wistar rats

Anticonflict-like effects of aqueous extract of flowers of Achillea millefolium L., a plant with purported anxiolytic actions, were studied in female Wistar rats during late proestrus or diestrus. During late proestrus (p < 0.05), control rats displayed reduced conflict behavior compared with diestrus. Diazepam (2.0 mg/kg; i.p.) reduced conflict behavior both during late proestrus (p < 0.05) or diestrus (p < 0.05). Doses of 8.0 mg/kg (p < 0.05), 10.0 mg/kg (p < 0.05) or 12.0 mg/kg (p < 0.05) of Achillea millefolium reduced conflict behavior during late proestrus. Conversely, during diestrus, only the dose of 12.0 mg/kg (p < 0.05) of Achillea millefolium L. reduced conflict behavior. In conclusion, the anticonflict-like actions of Achillea millefolium L. may vary according to the estrous cycle phase.

Condições afetivo-emocionais em mulheres com síndrome pré-menstrual através do Z-Teste e do IDATE

A presente pesquisa visou constatar as condições afetivo-emocionais em mulheres com síndrome pré-menstrual (SPM), comparadas com outras mulheres sem sintomas pré-menstruais. A amostra foi constituída de 43 universitárias, na faixa etária de 18 e 35 anos, distribuídas em dois grupos: Grupo 1, constituído de 25 mulheres com SPM, e Grupo 2 (Controle), de 18 mulheres sem estas disfunções. Foram utilizados como instrumentos a técnica de Zulliger (Z-Teste forma coletiva) e o Inventário de Ansiedade-Traço-Estado - IDATE (Spielberger), e para tratamento estatístico na análise comparativa dos dados o t-Teste para amostras independentes. O nível de significância escolhido foi p < 0.05. Os resultados indicaram que as mulheres do grupo com síndrome pré-menstrual reagem emocionalmente de forma mais intensa e têm tendência à perda de controle emocional em índice maior que as mulheres do grupo sem sintomas pré-menstruais.

Chronic episodic disorders in women

Chronic episodic disorders, such as depressive disorders, IBS, migraine, and FMS, have important commonalities, including cormorbidities, an absence of classic anatomic pathology in the tissues, a lack of objective findings on physical examination, and a lack of abnormal findings by routine laboratory and radiologic tests. These CED are more prevalent in women (perhaps due to changes in estrogen levels), are generally worsened by stress (with resultant hyperactivity of the HPA axis), and often improve with aerobic exercise and common classes of medications affecting serotonin function, such as antidepressants. Thus, an increased understanding of the CED may result in improved treatment and functioning of many patients.

Kava-Kava administration reduces anxiety in perimenopausal women

OBJECTIVE

Disturbances of mood, such as anxiety and depression, increase in the perimenopausal period. Hormone replacement therapy or neuroactive drugs represent useful treatments for these disturbances but may be contraindicated or not accepted. Herein it was investigated the efficacy of Kava-Kava, an extract of Piper Methysticum, on mood of perimenopausal women.

DESIGN

A 3-months randomized prospective open study investigating in perimenopausal women modifications induced by calcium supplementation (control; n=34), calcium plus Kava-Kava at the dose of 100 mg/day (n=15) or calcium plus Kava-Kava at the dose 200 mg/day (n=19). Anxiety was evaluated by the State Trait Anxiety Inventory (STAI); depression by the Zung's scale (SDS), and climacteric symptoms by the Greene's scale. Evaluations were performed at baseline and after 1 and 3 months.

RESULTS

In the control group during the 3 months, anxiety, depression and climacteric symptoms tended to decline, but not significantly. During Kava-Kava anxiety declined (P<0.001) at 1 (-3.8+/-1.03) and 3 (-5.03+/-1.2) months, depression declined at 3 months (-5.03+/-1.4; P<0.002) and climacteric score declined (P<0.0006) at 1 (-2.87+/-1.5) and 3 (-5.38+/-1.3) months. Only the decline of anxiety induced by Kava-Kava was significantly greater than that spontaneously occurring in controls (P<0.009).

CONCLUSIONS

The present data indicate that, in perimenopausal women, administration of Kava-Kava induces an improvement of mood, particularly of anxiety.

Efficacy and safety of oral and transdermal hormonal replacement treatment containing levonorgestrel

OBJECTIVES

The oral combined formulation of levonorgestrel with estradiol valerate (LNG+EV) has demonstrated to be effective on some postmenopausal symptoms. The availability of a transdermal HRT in sequential formulation with 17-beta-estradiol plus levonorgestrel (TSE2+TSLNG) induced us to do this control-study with the aim to evaluate the efficacy and safety of both oral and transdermal treatments.

METHODS

At baseline, the psychological symptoms with the psychometric scale SCL-90, the bone resorption with the measurement of the urinary levels of pyridinoline and dexoxypirydinoline, and the insulin and lipid metabolism were assessed in 30 postmenopausal women (PMW) and in 18 premenopausal women. Then, the PMW women were randomly divided in three groups: group A (N=10) assumed EV+LNG, group B (N=10) did not assume any treatment, group C (N=10) was treated with TSE2+TSLNG. The length of the study was 12 months. The aforementioned assessments were repeated at different time-intervals up to the end of the study.

RESULTS

The total score of SCL-90, the bone resorption, the levels of LDL-cholesterol, total-cholesterol and the parameters of insulin metabolism were higher in PMW than in premenopausal women. During the study, the SCL-90, the bone resorption, total-cholesterol, and LDL-cholesterol levels significantly decreased only in the groups A and C. By contrast, in the group B bone resorption significantly increased at the 12th month. During the treatments, insulin metabolism did not change in the groups A and B. In the group C the secretion of C-peptide and the C-peptide:insulin ratio after OGTT were significantly higher at the 12th month than before treatment. In all groups the endometrium thickness did not change during the study.

CONCLUSION

A 12-month of either oral or transdermal HRT containing levonorgestrel seems to exert beneficial effects on the main postmenopausal symptoms without negative interferences on the endometrium.

The relationship between hormone replacement therapy use and psychological symptoms: no effects found in a New Zealand sample

The use of hormone replacement therapy (HRT) for treatment of negative mood or affect, including problems such as depression, is not recommended in current public health guidelines or by reviewers of recent scientific findings. In this article we describe a preliminary examination of the relationship of HRT use to psychological affect and distress in the general population of middle-aged New Zealand women. A questionnaire survey was sent to 1,000 New Zealand women between the ages of 45-60 who were selected at random from the electoral roll. Among 494 respondents, no relationship was found between any measure of positive or negative mood or distress and HRT use. Other study variables, such as menopausal symptoms and self-reported health, were more likely to predict psychological outcomes. Our study supports previous findings. Nevertheless, the use of HRT to treat negative mood is currently widely accepted by the public and promoted by pharmaceutical companies.

Diverse actions of ovarian steroids in the serotonin neural system

All of the serotonin-producing neurons of the mammalian brain are located in 10 nuclei in the mid- and hindbrain regions. The cells of the rostal nuclei project to almost every area of the forebrain and regulate diverse neural processes from higher order functions in the prefrontal cortex such as integrative cognition and memory, to limbic system control of arousal and mood, to diencephalic functions such as pituitary hormone secretion, satiety, and sexual behavior. The more caudal serotonin neurons project to the spinal cord and interact with numerous autonomic and sensory systems. All of these neural functions are sensitive to the presence or absence of the ovarian hormones, estrogen and progesterone. We have shown that serotonin neurons in nonhuman primates contain estrogen receptor beta and progestin receptors. Thus, they are targets for ovarian steroids which in turn modify gene expression. Any change in serotoninergic neural function could be manifested by a change in any of the projection target systems and in this manner, serotonin neurons integrate steroid hormone information and partially transduce their action in the CNS. This article reviews the work conducted in this laboratory on the actions of estrogens and progestins in the serotonin neural system of nonhuman primates. Comparisons to results obtained in other laboratory animal models are made when available and limited clinical data are referenced. The ability of estrogens and progestins to alter the function of the serotonin neural system at various levels provides a cellular mechanism whereby ovarian hormones can impact cognition, mood or arousal, hormone secretion, pain, and other neural circuits.

A study of the psychological status and sexuality in middle-aged Bulgarian women: significance of the hormone replacement therapy (HRT)

OBJECTIVE

The psychoemotional and sexual status of Bulgarian urban postmenopausal women 10 years after the beginning of the period of extensive political, social, economic and cultural transitions was studied.

SUBJECTS AND METHODS

Three hundred and thirty-two postmenopausal women (83.5% in natural menopause and 16.5% in surgical menopause) and 295 women with normal menstrual cycle in several Bulgarian cities and the capital were studied. A campaign for free-of-charge bone density measurement was announced and the examined subjects filled in an individual anonymous questionnaire. SPSS for Windows version 8.0 was used for the statistical processing of the results. The comparison was made between normally menstruating women (n=295), postmenopausal women on hormone replacement therapy (HRT) (n=36) and postmenopausal subjects without HRT (n=296).

RESULTS

A significant correlation was observed between depression and sexual aversion, depression and pain with intercourse, depression and the change in the sexual life after menopause. The correlation between self-esteem and sexual thoughts, self-esteem and sexual desire, self-esteem and the arousal from the partner, self-esteem and orgasm also proved important. About 20% of the studied subjects reported depressive thoughts, 50% reported anxiety and the self-esteem was very low in 13%. These results can be explained in part with the economic stagnation in the country, the unemployment and uncertainty. However, 94% of Bulgarian women believe that they do well in life and rely on their professionalism and social positions. All parameters of sexual life are significantly lower in the postmenopausal group without HRT as compared both with menstruating women and postmenopausal women on HRT. Marital status influences them too.

CONCLUSION

The change in the sexuality is related to the decline in the estrogen activity, the influence of the psychosocial factors, the lack of a permanent intimate partner, and the derogatory attitude of the society towards the sexuality of postmenopausal women.

Attitudes towards menopause in a group of women followed in a public service for menopause counseling

This preliminary study addressed some specific attitudes towards menopause, and behavioral styles in menopausal women. The study was conducted during the period January-May 1998 at the Menopausal Service of the Magenta Hospital (Milano) in 88 women, representing almost one half of the patients followed during that period; 43 women were treated with HRT. Some traits characterizing women's life during menopause were examined, such as presence of disturbing physical symptoms, changes in interests and discovery of new interests, and feelings of loss and uselessness. We used different psychological tests in order to evaluate anxiety and depression, in particular, the STAI (State-Trait Anxiety Inventory), the SDS (Self-rating Depression Scale), and 16 cartoon-like images representing stereotypes of menopause. The answers of our subjects showed high individual variation, with negative symptoms (e.g., hot flashes, memory loss) frequently associated with positive experiences (e.g., new hobbies, new life-styles). However, even the most frequent negative symptom (memory loss) was reported only by 70%. The experience of a change represented by menopause was described both in terms of objective change (e.g., weight increase, hot flashes, memory loss), and of subjective change (e.g., character, feeling of not being attractive, new life-styles). Treatment with HRT seems to reduce the onset of hot flashes considerably. The occurrence of anxious-depressive states was comparable to that observed in other studies; it was not associated with HRT, but rather to losses (loss of desire, memory loss, insomnia). In conclusion, menopause represents a transitional moment in which physical and psychological changes are generally integrated by the persons experiencing them. In order to preserve a good quality of life in menopause, it seems relevant to check memory loss and stabilize the mood in persons who are most "at risk" of psychological disease.

A preliminary study of hormone replacement therapy and psychological mood states in perimenopausal women

Hormone replacement therapy (HRT) for perimenopausal women has been suggested to minimize the physical symptoms of menopause and improve mood and psychological functioning; however, the therapy remains controversial. In this study the effects of such therapy (comprising tablets, patches, and implants) on mood states was investigated within a sample of 70 perimenopausal women who were attending a family planning clinic within the Brisbane metropolitan area. On a battery of standardized questionnaires, including the General Health Questionnaire, the Profile of Mood States, the Eysenck Personality Questionnaire, and the Menstrual Distress Questionnaire, those 35 women who were using hormone replacement therapy prescribed by the clinic physician reported significantly lower scores on anxiety, insomnia, and somatic symptoms than did a comparable group of 35 untreated perimenopausal women. These findings provide some tentative support for the beneficial effects of the therapy on physical symptoms and psychological mood states related to the onset of menopause. Given increased life expectancy, there is a growing need for research into issues of aging.

[Women's attitudes to menopause and predictive variables]

OBJECTIVE

To find what women's attitudes to the menopause are and how these attitudes relate to certain personal variables.

DESIGN

Multi-centre, transversal study.

SETTING

5 clinics at three urban and teaching health centres in Granada.

PARTICIPANTS

A systematic randomised sample of women = 18 who attended on demand in June 1998: alpha = 0.05, accuracy = 3 and standard deviation from the scale of attitudes (SA), found through prior sampling, was 15.4. N = 101 women.

INTERVENTIONS

Questionnaire through interview after consultation.

MEASUREMENTS AND MAIN RESULTS

Dependent variable: scale of attitudes to the menopause with 29 items.

INDEPENDENT VARIABLES

age, marital status, educational qualifications, work situation, cultural group, religion, continuity with her doctor, utilisation, menopausal status, perception of autonomy, opinion of the menopause, feelings towards the menopause, perceived health.

ANALYSIS

homogeneity and validity of SA. Descriptive, univariate analysis of SA with independent variables. Multiple linear regression: we found 7 factors that explained 66.5% of variance. Age 43.4 +/- 17.5. 50.5% had not reached the menopause; 10.9% were in the peri-menopause; and 37.6% in the menopause. 70.3% had feelings of relief or were neutral; 54.5% had a positive view; and 21.8% expressed no opinion. The variables explaining attitudes were feeling, continuity, opinion, utility, autonomy and perceived health.

CONCLUSIONS

Women had positive or neutral feelings and opinions about the menopause. Their attitudes to it were related to these variables and not to other social or demographic variables or to their menopausal status.

Plasma 5alpha-androstane-3alpha,17betadiol, an endogenous steroid that positively modulates GABA(A) receptor function, and anxiety: a study in menopausal women

We tested the hypothesis that changes in endogenous neuroactive steroids acting as positive allosteric modulators of gamma-aminobutyric acid (GABA)(A) receptors may be related to the menopause-associated mood alterations. The study sample consisted of twenty five drug-free menopausal women, 1-3 years since the onset of menopause, homogeneous for age and body mass index (BMI) and without personal history of psychiatric, metabolic or endocrine disorders. Depression and anxiety-related symptoms were assessed with the Zung Self-administered Depression Scale (ZSDS) and the Cornell's Dysthymia Rating Scale (CDRS). The cut-off value predicted by the ZSDS index defined two groups of women (asymptomatic [35.5+/-4.6, n=12] and symptomatic [60.8+/-7.9, n=13]), that were also significantly different according to the CDRS scores (10.6+/-3.4 and 31.5+/-12, respectively, P<0.05). Upon evaluation of the scores relative to the anxiety factor of the CDRS (items 11-15) the symptomatic, but not the asymptomatic, group showed a moderate level of anxiety. The plasma concentrations of several neuroactive steroids were measured, after extraction and HPLC purification, by radioimmunoassay with specific antisera. Only dehydroepiandrosterone and its metabolite 5alpha-androstane-3alpha,17betadiol (3alpha-ADIOL), a positive allosteric modulator of GABA(A) receptors, were significantly (P<0.05 and P<0.005) higher (+110% and +64%, respectively) in the asymptomatic group. A highly significant and negative correlation (r=-0.672, P=0.003) was found between the plasma 3alpha-ADIOL concentrations and the scores of the anxiety factor of the CDRS. These data suggest that endogenous 3alpha-ADIOL modulates the central GABAergic tone and that higher 3alpha-ADIOL concentrations could have a role in preventing the expression of anxiety in the asymptomatic women.
