Effects of antidepressants on quality of life in women with premenstrual dysphoric disorder

The impact of pharmacotherapy for premenstrual dysphoric disorder on sleep

Premenstrual dysphoric disorder (PMDD) affects a subset of women of reproductive age, characterized by severe mood disturbances and physical symptoms during the luteal phase of the menstrual cycle. Symptoms include mood swings, irritability, anxiety, fatigue, physical discomfort, and disruptions to sleep and circadian rhythms, such as altered melatonin secretion. Despite the prevalence of these symptoms, the impact of PMDD treatments on sleep and circadian markers, like melatonin, remains insufficiently understood. This review examines how dysregulated serotonin signaling, disrupted allopregnanolone activity (a neurosteroid derived from progesterone), and aberrant circadian rhythms contribute to PMDD. It also explores the effects of pharmacological treatments, including selective serotonin reuptake inhibitors, on sleep and melatonin regulation, and how these factors influence treatment outcomes. Additionally, the use of hypnotics and sedatives to manage sleep disturbances in PMDD is considered, weighing their potential benefits and risks. A deeper understanding of the interaction between PMDD symptoms, sleep, and circadian rhythms is crucial for developing more effective treatments. Further research is needed to explore the relationship between symptom management, sleep patterns, and circadian function in PMDD, and to determine how these factors can be optimized to improve clinical outcomes and quality of life for women affected by the disorder.

Premenstrual syndrome and sleep disturbances: Results from the Sao Paulo Epidemiologic Sleep Study

The aim of this study is to compare sleep characteristics between women with premenstrual syndrome (PMS) and a control group. The data were extracted from an epidemiologic survey conducted in Sao Paulo (EPISONO), Brazil, which used subjective assessments and objective polysomnography records to analyze subjects' sleep pattern. Subjective questionnaires used in this study were Women's Questionnaire, Pittsburgh Sleep Quality Index, Epworth sleepiness scale, Insomnia Severity Index and the general sleep questionnaire. The presence of PMS was obtained by a direct question in the Women's Questionnaire. The survey included 230 women, of whom 72.6% reported PMS. The PMS group had poorer sleep quality, a higher perception of unrefreshing sleep and more subthreshold insomnia. Participants with PMS had an increased total sleep time recorded by polysomnography and a lower saturation of peripheral oxygen. It is still unkown the mechanism behind PMS and the sleep-wake cycle. In the other hand, it is clear that PMS play a role in sleep, since women with this disorder has a poor quality of sleep and it is not refreshing. Better knowledge about this syndrome and its outcomes can help to improve their well-being and develop more precise therapeutic approaches.

Endogenous inhibition of pain and spinal nociception in women with premenstrual dysphoric disorder

Purpose

Premenstrual dysphoric disorder (PMDD) is characterized by severe affective and physical symptoms, such as increased pain, during the late-luteal phase of the menstrual cycle. The mechanisms underlying hyperalgesia in women with PMDD have yet to be identified, and supraspinal pain modulation has yet to be examined in this population. The present study assessed endogenous pain inhibitory processing by examining conditioned pain modulation (CPM, a painful conditioning stimulus inhibiting pain evoked by a test stimulus at a distal body site) of pain and the nociceptive flexion reflex (NFR, a spinally-mediated withdrawal reflex) during the mid-follicular, ovulatory, and late-luteal phases of the menstrual cycle.

Methods

Participants were regularly-cycling women (14 without PMDD; 14 with PMDD). CPM was assessed by delivering electrocutaneous test stimuli to the sural nerve before, during, and after a painful conditioning ischemia task. Participants rated their pain to electrocutaneous stimuli, and NFR magnitudes were measured. A linear mixed model analysis was used to assess the influence of group and menstrual phase on CPM.

Results

Compared with controls, women with PMDD experienced greater pain during the late-luteal phase and enhanced spinal nociception during the ovulation phase, both of which were independent of CPM. Both groups showed CPM inhibition of pain that did not differ by menstrual phase. Only women with PMDD evidenced CPM inhibition of NFR.

Conclusion

Endogenous modulation of pain and spinal nociception is not disrupted in women with PMDD. Additionally, greater NFR magnitudes during ovulation in PMDD may be due to tonically-engaged descending mechanisms that facilitate spinal nociception, leading to enhanced pain during the premenstrual phase.

Attitudes of Spanish women toward premenstrual symptoms, premenstrual syndrome and premenstrual dysphoric disorder: results of a nationwide survey

OBJECTIVE

To assess the attitudes of women with premenstrual symptoms in relation to their perception of complaints and request for medical advice.

STUDY DESIGN

Cross-sectional study of a representative cohort of 2018 Spanish women aged 15-49 years. Participants were personally interviewed at home and completed the premenstrual symptoms screening tool.

RESULTS

A total of 1554 women (73.7%) complained of some of the premenstrual symptoms during the last 12 menstrual cycles. The prevalence of moderate or severe premenstrual syndrome (PMS) was 8.9% and the prevalence of premenstrual dysphoric disorder (PMDD) 1.1%. Only 291 (18.7%) women had sought medical advice. The main reason given by 90.6% of symptomatic women for not seeking medical consultation was to consider that symptoms were normal. A total of 175 (60.1%) women received pharmacological treatment (hormonal contraceptives in 95% followed by analgesics in 50% and anti-inflammatory agents in 44%), 20% were not treated because physicians considered that symptoms were not important and would disappear spontaneously, and 12% received only advice to change life style.

CONCLUSION

Women suffering from PMS or PMDD do not usually seek medical advice and among those seeking medical care, in many cases, an adequate response to their demands is not obtained.

Duloxetine treatment for women with premenstrual dysphoric disorder: a single-blind trial

Premenstrual dysphoric disorder (PMDD) affects 3-8% of women of reproductive age and is characterized by severe mood symptoms that cause important functional impairment. Serotonergic antidepressants appear to be an effective treatment for this disorder. The purpose of this study was to collect evidence on the efficacy and tolerability of duloxetine, a dual reuptake inhibitor of serotonin and norepinephrine, in the treatment of PMDD. We conducted a pilot, single-blind, non-controlled, fixed-dose trial. After two cycles for diagnosis confirmation, including a single-blind placebo cycle, 20 women with PMDD were treated continuously for three menstrual cycles with 60 mg/d duloxetine. The primary measure of the efficacy of treatment with duloxetine was the significant reduction in premenstrual symptoms demonstrated by the comparison between the mean Daily Record of Severity of Problems (DRSP) scores at baseline to endpoint (p=0.0002). Statistically significant symptom reduction was observed in the first treatment cycle and throughout all the treatment phase. Clinical response, defined as a reduction 50% of baseline premenstrual symptoms, occurred in 65% of subjects (intention-to-treat population). Significant improvements were demonstrated by secondary measures, including reduction in self-rated functional impairment (p=0.01) and improvement in quality of life (p=0.04). The main side-effects associated with duloxetine were dry mouth, nausea, drowsiness, insomnia, decreased appetite, decreased libido, and sweating. Duloxetine was effective and generally well tolerated in the treatment of PMDD. Further large-scale, double-blind, placebo-controlled studies are needed to evaluate duloxetine as an additional treatment strategy for the management of PMDD.

Premenstrual syndrome and premenstrual dysphoric disorder: quality of life and burden of illness

Premenstrual symptoms are distressing for up to 20% of reproductive-aged women and are associated with impairment in interpersonal or workplace functioning for at least 3-8%. Typical symptoms of premenstrual syndrome and the severe form, premenstrual dysphoric disorder, include irritability, anger, mood swings, depression, tension/anxiety, abdominal bloating, breast pain and fatigue. The symptoms recur monthly and last for an average of 6 days per month for the majority of the reproductive years. For women with premenstrual dysphoric disorder, the symptoms can be as disabling as major depressive disorder. It has been estimated that affected women experience almost 3000 days of severe symptoms during the reproductive years. Until two decades ago, there were no effective treatments for severe premenstrual syndrome. Even in 2000, almost three-quarters of women in the USA with premenstrual disorders either did not seek help or sought treatment unsuccessfully from at least three clinicians for over 5 years. This review will focus on the epidemiology, diagnosis, treatment outcomes, quality of life and burden of illness for premenstrual disorders.

Clinical factors influencing the prescription of antidepressants and benzodiazepines: results from the European study of the epidemiology of mental disorders (ESEMeD)

OBJECTIVE

To examine factors associated with the use of antidepressants (AD) and benzodiazepines (BZD) in 6 European countries.

METHODS

A cross-sectional, population-based study was conducted in: Belgium, France, Germany, Italy, the Netherlands and Spain. 21,425 non-institutionalized individuals aged 18 years and over were interviewed using the third version of the Composite International Interview (CIDI-3.0). Respondents were asked about AD and BZD use, and whether they consulted formal health services for emotional problems in the previous year. Sociodemographic variables, presence of mood/anxiety disorders and of painful physical symptoms were collected.

RESULTS

34.38% and 9.17% of the sample reported the use of AD and BZD respectively in the previous 12 months. Only 29.95% of subjects with a 12-month prevalence of major depressive episode (MDE) had been taking antidepressants. After controlling for several clinical and non-clinical factors, help seeking for emotional problems was the most important independent predictor for the use of AD or BZD (OR: 13.58 and 5.17, respectively). Higher age was the second important predictor (OR: 6.52 and 4.86, respectively). A 12-month or lifetime prevalence of MDE or an anxiety disorder were also predictors for AD or BZD use (OR for MDE: 5.00 and 2.82, OR for anxiety disorders: 2.13 and 1.85). Finally, the presence of painful physical symptoms also predicted the use of AD and BZD, while female gender, lower education and higher age predicted only the use of BZD.

CONCLUSION

Less than one third of subjects with a 12-month prevalence of MDE had been taking antidepressants. But seeking help for emotional problems was a more important predictor of the use of ADs or BZDs than a formal (DSM-IV) psychiatric diagnosis, suggesting that usage of ADs is not always according to the licensed DSM-IV indication.

The pharmacologic management of premenstrual dysphoric disorder

Premenstrual dysphoric disorder (PMDD) is characterized by physical, affective and behavioral symptoms that are linked to the luteal phase of the menstrual cycle and relieved soon after the onset of menses. The disorder is chronic and exerts a major impact on personal relationships and occupational productivity for the estimated 6% of reproductive-aged women who fulfill strict PMDD criteria and the almost 20% of women who nearly meet these criteria. There are now various pharmacologic options that have demonstrated efficacy for PMDD and two of these approaches have an approved indication for treatment from the US FDA: three selective serotonin re-uptake inhibitors; and for women who also desire hormonal contraception, a low dose oral contraceptive pill containing the progestin drospirenone, in a new dosing regimen. Due to the unique pathophysiology of the disorder, the selective serotonin re-uptake inhibitors can be effectively administered intermittently, with dosing limited to the luteal phase of the cycle (2 weeks prior to menses). In the future, new pharmacotherapy will likely evolve from research evaluating other hormonal formulations that inhibit ovulation, without simulating PMDD-like symptoms, or novel pharmacologic agents that modulate the central neurotransmission.

Psychological aspects of premenstrual syndrome

Premenstrual syndrome (PMS) is a group of psychological and physical symptoms which regularly occur during the luteal phase of the menstrual cycle and resolve by the end of menstruation. The severe and predominantly psychological form of PMS is called premenstrual dysphoric disorder (PMDD). The exact aetiology of PMS is not known. PMS results from ovulation and appears to be caused by the progesterone produced following ovulation in women who have enhanced sensitivity to this progesterone. The increased sensitivity may be due to neurotransmitter (mainly serotonin) dysfunction. The key diagnostic feature is that the symptoms must be absent in the time between the end of menstruation and ovulation. Prospective symptom rating charts are used for this purpose. Treatment is achieved by suppression of ovulation or reducing progesterone sensitivity with selective serotonin re-uptake inhibitors. In this chapter, the authors describe the aetiology, symptoms, diagnosis and evidence-based management of premenstrual syndrome.
