Attitudes of women who are currently using or recently stopped estrogen replacement therapy with or without progestins: results of the AWARE survey.

OBJECTIVE: To examine the level of awareness of the findings of the Women's Health Initiative (WHI) study among recent users of hormone therapy (HT). METHODS: A survey was conducted on Canadian women older than 45 years of age who had used either an oral, topical, or vaginal HT within the preceding 3 years. Questionnaires were mailed to a random sample of 210 eligible women within an academic subspecialty rheumatology/osteoporosis practice between April and June 2003. Questionnaires were also provided upon request to women attending tertiary care multidisciplinary clinics and 6 community pharmacies in Hamilton, Ontario. The 98 questions in the survey were either categorical in nature (yes or no response) or followed by a Likert scale. Using chi-square and Student t tests, the responses of women who used combination estrogen/progestin were compared to those who used estrogen alone. RESULTS: Of the 161 women who responded to the survey (128 from the osteoporosis practice, 33 from other clinics and pharmacies), 102 (63%) had used HT for more than 5 years. Ninety-one of 159 respondents (57%) discontinued HT, and 63% (57/91) of those stopped using HT after publication of the WHI principal findings. Sixty-four percent (33/52) of women on combination estrogen/progestin discontinued HT, compared to 50% (46/93) who were on estrogen only, and 5 other women who also discontinued HT but did not know what type of preparation they had been taking (P = .04 for the difference in rates between the 3 groups). Knowledge of the findings of the estrogen/progestin arm of the WHI study did not significantly differ among users of different types of hormone preparations. Of the women who indicated that they did not know if HT affected the risk of WHI-studied medical conditions, 44% (69/156) indicated being unaware of HT risks for stroke, 28% (44/157) for hip fracture, 39% (60/155) for myocardial infarction, 25% (39/155) for breast cancer, and 48% (73/152) for blood clots. Women who had recently taken HT generally did not regret their use of HT. CONCLUSION: Although many women discontinued HT following the publication of the principal findings of the estrogen/progestin arm of the WHI study, the majority of these women lacked a clear understanding of those findings.

Perinatal risks of untreated depression during pregnancy.

OBJECTIVE: To review the literature on the perinatal risks involved in untreated depression during pregnancy. METHOD: We searched Medline and medical texts for all studies pertaining to this area up to the end of April 2003. Key phrases entered were depression and pregnancy, depression and pregnancy outcome, and depression and untreated pregnancy. We did not include bipolar depression. RESULTS: While there is wide variability in reported effects, untreated depression during pregnancy appears to carry substantial perinatal risks. These may be direct risks to the fetus and infant or risks secondary to unhealthy maternal behaviours arising from the depression. Recent human data suggest that untreated postpartum depression, not treatment with antidepressants in pregnancy, results in adverse perinatal outcome. CONCLUSION: The biological dysregulation caused by gestational depression has not received appropriate attention: most studies focus on the potential but unproven risks of psychotropic medication. No in-depth discussion of the role of psychotherapy is available. Because they are not aware of the potentially catastrophic outcome of untreated maternal depression, this imbalance may lead women suffering from depression to fear teratogenic effects and refuse treatment.

Hormones and mood: from menarche to menopause and beyond.

The lifetime prevalence of mood disorders in women is approximately twice that of men. The underlying causality of this gender difference is not yet understood. There is increasing scientific attention to the modulation of the neuroendocrine system by fluctuating gonadal hormones. This review attempts to summarize our current state of knowledge on the role and potential relevance of estrogen and other sex steroids to psychiatric disorders specific to women from menarche to menopause. The sudden appearance of higher levels of estrogen in puberty alters the sensitivity of the neurotransmitter systems. Moreover, the constant flux of estrogen and progesterone levels throughout the reproductive years portends constant modification of the neurotransmitter systems. Premenstrual syndromes may be the result of an altered activity or sensitivity of certain neurotransmitter systems. Pregnancy and delivery produce dramatic changes in estrogen and progesterone levels as well as significant suppression along the HPA axis, possibly increasing vulnerability to depression. At menopause, estrogen levels decline while pituitary LH and FSH levels increase. The loss of modulating effects of estrogen and progesterone may underlie the development of perimenopausal mood disorders in vulnerable women. The pattern of neuroendocrine events related to female reproduction is vulnerable to change and is sensitive to psychosocial, environmental, and physiological factors. Further research is needed to be able to identify specific genetic markers which might help us better understand how the balance between estrogen, progesterone, testosterone, and other steroid hormones affect neurotransmitter function.

A biopsychosocial approach to premenstrual dysphoric disorder.

Though epidemiological data is difficult to collect, existing evidence indicates that there is a small but significant population of women in whom premenstrual symptoms, and particularly affective symptoms, severely impair functioning. Although PMDD is predominantly regarded as a biologically based illness, there is strong evidence that variables such as life stress, history of sexual abuse, and cultural socialization are important determinants of premenstrual symptoms. In diagnosing and treating PMDD patients, attention to biological and sociocultural variables is recommended.

Treatment of premenstrual dysphoria with selective serotonin re-uptake inhibitors: focus on safety.

Many women experience physical or mood symptoms associated with the menstrual cycle. For approximately 3 - 8% of women, the symptoms are severe enough to significantly affect social, domestic and occupational functioning. This cluster of primarily emotional and behavioural symptoms is now labelled premenstrual dysphoric disorder (PMDD). Women who meet criteria for PMDD do not usually respond to conservative interventions; selective serotonin re-uptake inhibitors (SSRIs) taken either daily or intermittently are considered to be an effective first-line therapy for this population. In this paper, the authors report on the efficacy and tolerability of SSRIs that are currently recognised as the treatment of choice for PMDD.

Testosterone and prolactin are associated with emotional responses to infant cries in new fathers.

To determine the responsiveness of new fathers and non-fathers toward infant cues, we exposed fathers and non-fathers to infant cries and to control stimuli and we measured affective, heart-rate, and endocrine responses, including salivary testosterone and cortisol and plasma prolactin concentrations prior to and after cry presentations. We found that (1) fathers hearing the cry stimuli felt more sympathetic and more alert compared to groups who did not hear the cries or to non-fathers who heard the cries; (2) fathers and non-fathers with lower testosterone levels had higher sympathy and/or need to respond to the infant cries than fathers with higher testosterone levels; (3) fathers with higher, as opposed to lower, prolactin levels were also more alert and more positive in response to the cries; (4) fathers hearing the cry stimuli showed greater percentage increase in testosterone than fathers not hearing the cry stimuli; (5) experienced fathers hearing the cries showed a greater percentage increase in prolactin levels compared to first-time fathers or to any group of fathers hearing control stimuli; finally, (6) partial correlations with parity and experience entered as a covariates indicated that both experience and testosterone contributed to the variance in fathers' affective responses to infant cries. Taken together, these results indicate that, as with a number of other biparental species, human fathers are more responsive to infant cues than are non-fathers and fathers' responses to infant cues are related to both hormones and to caregiving experience.

The roots of depression in adolescent girls: is menarche the key?

Before adolescence, the rates of depression are similar in girls and boys (or are slightly higher in boys). Yet with the onset of puberty, the gender proportion of depression dramatically shifts to a two girls to one boy ratio. What, then, is the relationship between menarche and the onset of major depression in early adolescence? Recent literature intimates that vulnerability to depression may be rooted in an intricate meld of genetic traits, normal female hormonal maturational processes, and gender socialization. Information regarding gender differences in the presentation of depressive symptoms is provided along with biologic, psychologic, and sociologic factors contributing to depression in adolescent girls. The burden of illness associated with onset of depression after menarche reinforces the importance of prevention or else expeditious recognition and intervention.

Sertraline and/or interpersonal psychotherapy for patients with dysthymic disorder in primary care: 6-month comparison with longitudinal 2-year follow-up of effectiveness and costs.

BACKGROUND: There is little information on the long-term effects and costs of a combination of Sertraline and interpersonal psychotherapy (IPT) for the treatment of dysthymia in primary care. METHODS: In a single-blind, randomized clinical trial, 707 adults (18-74 years of age inclusive) with DSM-IV dysthymic disorder, with or without past and/or current major depression, as an acute or chronic episode, in a community-based primary care practice in Ontario, Canada, were randomized to treatment with either Sertraline alone (50-200 mg), or IPT alone (10 sessions), or Sertraline plus IPT combined. In the acute treatment phase (first 6 months) all groups received full active treatment. This was followed by an additional 18-month naturalistic follow-up phase. Subjects were assessed for effectiveness of treatment in reducing depressive symptoms using the Montgomery Asberg Depression Rating Scale (MADRS) at 6 months and twice again during the 18-month follow-up by blind independent observers. Treatment costs and subjects' use of other health and social services were also investigated. RESULTS: At 6 months, 586 subjects completed the MADRS questionnaire. There was a significant difference (P=0.025) in mean MADRS scores: 14.3 (Group I); 14.9 (Group II); 16.8 (Group III), using analysis of covariance. Response (40% improvement) rates were 60.2% for Sertraline alone, 46.6% for IPT alone, and 57.5% for Sertraline augmented by IPT (P=0.02). At 2 years, 525 subjects were retained for follow-up. There was no statistically significant difference between Sertraline alone and Sertraline plus IPT in symptom reduction. However, both were more effective than IPT alone in reducing depressive symptoms (P=0.03). There was a statistically significant difference between groups in costs for use of health and social services. The IPT treatment groups had the lower costs for use of health and social services. CONCLUSIONS: Sertraline or Sertraline plus IPT was more effective than IPT alone after 6 months. Over the long term (2 years), all three treatments provide reasonably effective treatment for reducing symptoms of dysthymia, but Sertraline or combining Sertraline with IPT is more effective than IPT alone. Of these two more effective treatments, subjects in the Sertraline plus IPT group had less health and social service costs by $480 per person over 2 years. These findings underscore the effects of combining pharmacotherapy and psychotherapy and the economic value of this more comprehensive treatment of dysthymia in primary care.

Postnatal depression: a few simple questions.

The rate of past and family psychiatric history was ascertained in 254 women diagnosed with postnatal depression. Probands and first-degree relatives were interviewed to establish lifetime and current major psychiatric diagnoses. 78.3% of the women studied had a past and/or family psychiatric history. These data confirm the importance of these variables when screening women who may be at risk for postnatal depression.

Expert guidelines for the treatment of severe PMS, PMDD, and comorbidities: the role of SSRIs.

The hallmark feature of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) is the predictable, cyclic nature of symptoms or distinct on/offness that begins in the late luteal phase of the menstrual cycle and remits shortly after the onset of menstruation. PMDD is distinguished from PMS by the severity of symptoms, predominance of mood symptoms, and role dysfunction, particularly in personal relationships and marital/family domains. Several treatment modalities are beneficial in PMDD and severe PMS, but the selective serotonin reuptake inhibitors (SSRIs) have emerged as first-line therapy. The SSRIs can be administered continuously throughout the entire month, intermittently from ovulation to the onset of menstruation, or semi-intermittently with dosage increases during the late luteal phase. These guidelines present practical treatment algorithms for the use of SSRIs in women with pure PMDD or severe PMS, PMDD and underlying subsyndromal clinical features of mood or anxiety, or premenstrual exacerbation of a mood/anxiety disorder.

Paroxetine controlled release for premenstrual dysphoric disorder: a double-blind, placebo-controlled trial.

BACKGROUND: Better characterization of safety and efficacy of multiple doses of selective serotonin reuptake inhibitors for the treatment of a wider range of symptoms of premenstrual dysphoric disorder (PMDD) will provide clinicians with flexibility to provide symptom relief along with acceptable tolerability. This study was designed to assess the efficacy and tolerability of multiple doses of paroxetine controlled release (CR) in PMDD. METHODS: In a multicenter (43 outpatient U.S. sites), placebo-controlled trial, 327 females aged 18 to 45 years, with regular menstrual cycles, meeting DSM-IV criteria for PMDD, were randomly assigned to receive paroxetine CR 12.5 mg; paroxetine CR 25 mg; or placebo, once daily, for up to three treatment cycles. The primary efficacy outcome was change from baseline to end point in mean luteal phase Visual Analogue Scale-Mood (irritability, tension, affective lability, depressed mood) score. RESULTS: At end point, subjects treated with paroxetine CR (12.5 mg and 25 mg) demonstrated significant improvement in VAS-Mood scores compared with those who received placebo (paroxetine CR 12.5 mg mean treatment difference vs. placebo, -8.7 mm; 95% CI, -15.7, -1.7; p =.015; paroxetine CR 25 mg mean treatment difference vs. placebo, -12.1 mm; 95% CI, -18.9, -5.3; p <.001). Results were also significant across measures of physical symptoms and social functioning. Paroxetine CR was well tolerated; 9.5% of subjects treated with 12.5 mg and 13.5% of subjects treated with 25 mg withdrew from the trial due to adverse events, compared with 6.5% of subjects in the placebo group. CONCLUSIONS: Both doses of paroxetine CR 12.5 mg and 25 mg daily are effective and well tolerated in patients who suffer from PMDD. Efficacy with both doses affords greater flexibility to the prescribing physician.
