Hot flashes in the late reproductive years: risk factors for Africa American and Caucasian women

Hot flashes are a primary reason that midlife women seek medical care, but there is little information about the onset or the predictors of hot flashes in the years before the menopause. This study examines women's experience of hot flashes in the late reproductive years, comparing African American and Caucasian women, and identifies hormonal, behavioral, and environmental risk factors for hot flashes associated with ovarian aging. Data are from a population-based prospective cohort study of ovarian aging in women who were ages 35--47, in general good health, and had regular menstrual cycles at study enrollment. Hot flashes were assessed by subject report in a structured interview at the first follow-up period and correlated highly with previous prospective daily ratings of hot flashes (p = 0.0001). Blood samples were obtained in the first 6 days of the menstrual cycle in two consecutive cycles at enrollment and two consecutive cycles at follow-up. Predictor variables include hormone measures, structured interview, and standard questionnaire data. Thirty-one percent of the sample (n = 375) reported hot flashes (mean age 41 years). In bivariate analysis, more African American than Caucasian women reported hot flashes (38% vs. 25%, p = 0.01). Significant predictors of hot flashes in the final multivariable logistic regression model were higher follicle-stimulating hormone (FSH) levels (odds ratio [OR] 3.19), anxiety (OR 1.06), baseline menopausal symptoms (OR 4.91), alcohol use (OR 1.09), body mass index (BMI) (OR 1.04), and parity (OR 1.20). Race did not predict hot flashes after adjusting for these variables. Hot flashes commonly occur before observable menstrual irregularities in the perimenopause and are associated with both hormonal and behavioral factors. The association of hot flashes with increased body mass (BMI) challenges the current "thin" hypothesis and raises important questions about the role of BMI in hormone dynamics in the late reproductive years.

Predictors of response to sertraline treatment of severe premenstrual syndromes

BACKGROUND

Serotonergic antidepressant medications have demonstrated efficacy in the treatment of severe premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). Over 60% of subjects responded well to sertraline treatment for PMS and PMDD in double-blind controlled studies. However, no studies have evaluated the predictors of treatment response for this disorder. The current study examined pretreatment demographic, medical history, and clinical symptom predictors of sertraline response in PMS and PMDD treatment.

METHOD

Sixty-two subjects diagnosed with severe PMS (according to the Daily Symptom Report and global ratings of functional impairment) or PMDD (DSM-IV) received sertraline treatment as part of a randomized, double-blind, placebo-controlled treatment efficacy study. All subjects completed 3 screening cycles, including a single-blind placebo washout cycle, prior to 3 cycles of double-blind treatment. Outcome was assessed across the domains of PMS symptoms and quality of life. Demographic, medical history, and symptom variables were used to predict sertraline response.

RESULTS

Baseline postmenstrual symptom ratings were significantly and independently associated with posttreatment PMS symptoms in multivariate analysis. Premenstrual and postmenstrual ratings of depression, medical history variables, and demographic variables were not significantly predictive of response to sertraline.

CONCLUSION

Baseline postmenstrual symptom ratings controlled for baseline premenstrual symptoms were associated with PMS symptoms at sertraline treatment endpoint. The findings suggest that nonmenstrual-related baseline characteristics other than depression may influence sertraline treatment outcome in patients with higher postmenstrual symptom levels.

Prior benzodiazepine exposure and benzodiazepine treatment outcome

BACKGROUND

We examined discontinuation symptoms following brief benzodiazepine therapy (8 weeks) and intermittent benzodiazepine therapy (2 weeks with at least 2 weeks without drug) and associations with prior benzodiazepine use. The hypothesis was that prior benzodiazepine use would predispose patients to more severe discontinuation symptoms.

METHOD

Data were drawn from 3 double-blind, randomized, placebo-controlled, published treatment trials: alprazolam for patients with premenstrual syndrome (PMS) and diazepam and lorazepam for patients with generalized anxiety disorder (GAD). The PMS group provided prospective daily symptom ratings, which allowed ongoing investigation of effects of prior treatment. In the GAD groups, taper outcome was examined after 8 weeks of benzodiazepine therapy as a function of prior benzodiazepine use and as a function of time since last prior benzodiazepine use. Symptom scores were analyzed using t statistics in the PMS group and analysis of covariance with 8-week scores as the covariate in the GAD groups.

RESULTS

The PMS subjects reported no increase in symptom scores and no significant difference from placebo-treated subjects during taper and discontinuation of alprazolam in the follicular phase of each treatment cycle. In the GAD trials, the results of treatment discontinuation did not differ significantly as a function of presence or absence of prior benzodiazepine use or as a function of time since last benzodiazepine use.

CONCLUSION

These preliminary data fail to support the hypothesis that prior benzodiazepine use predisposes patients to more severe discontinuation symptoms when treatment is brief and doses are low.

Psychosocial functioning in women with premenstrual dysphoric disorder before and after treatment with sertraline or placebo

BACKGROUND

The objective of this study was to evaluate the pretreatment psychosocial functioning of women with premenstrual dysphoric disorder (PMDD) and the effect of sertraline treatment on psychosocial functioning in these patients.

METHOD

Two hundred forty-three women recruited from 12 university-affiliated sites and meeting DSM-IV criteria for PMDD completed 1 cycle of single-blind placebo and were randomly assigned to flexible dose sertraline or placebo for 3 cycles. Psychosocial functioning was assessed by the Daily Record of Severity of Problems (DRSP), the Social Adjustment Scale (SAS), and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q).

RESULTS

SAS scores during the follicular phase were similar to SAS scores of community norms, whereas the pretreatment SAS and Q-LES-Q scores during the luteal phase were similar to scores of women with depressive disorders. Sertraline was significantly more effective than placebo in improving psychosocial functioning as measured by the SAS, the Q-LES-Q, and the 3 DRSP items of impaired productivity, interference with social activities, and interference with relationships with others. Improvement in psychosocial functioning assessed by SAS and Q-LES-Q correlated with improvement in symptomatology assessed by the Clinical Global Impressions-Improvement (CGI-I) scale and the Hamilton Rating Scale for Depression (HAM-D). Remitters (CGI-I score of 1) were more likely to function better at baseline and showed larger improvements in functioning and quality of life with treatment compared with nonremitters.

CONCLUSION

Sertraline was superior to placebo in improving psychosocial functioning in women with PMDD as reflected by SAS, Q-LES-Q, and DRSP measures. Functional improvement correlated with improvement in premenstrual symptomatology and was apparent by the second cycle of treatment. Comparison of pretreatment SAS scores in women with PMDD with the scores of other populations of women documents the degree of luteal phase functional impairment in women with PMDD and a relative absence of follicular phase impairment.

Differences in urinary excretion patterns of the hLH beta core fragment in premenopausal, perimenopausal, and postmenopausal women

OBJECTIVE

The heterodimeric luteinizing hormone beta core fragment (hLH beta cf) is a highly stable urinary analyte reflective of circulating hLH. It is measured easily because of its high molar content and has none of the multiple isoforms and subunit dissociation problems of LH urinary measurements. As part of a long-term effort to develop new biochemical assays to stage women during the perimenopausal transition, we have examined the patterns of urinary excretion of this metabolite of hLH in premenopausal, perimenopausal, and postmenopausal women.

DESIGN

We measured the concentration of the hLH beta cf in 10 consecutive first morning void urine specimens from premenopausal, perimenopausal, and postmenopausal women. Day 1 of collection was the first day of menses in the cycling women.

RESULTS

Postmenopausal women exhibited a widely fluctuating pattern of LH beta core fragment excretion, which is not correlated with hLH measured by immunofluorometric assay or with follicle-stimulating hormone measured by immunofluorometric assay. The postmenopausal group was easily distinguished from premenopausal women on the basis of an area-under-the-curve concentration function. Perimenopausal women displayed intermediate hLH beta cf concentrations; some clearly were in postmenopausal ranges, and others were in the premenopausal ranges.

CONCLUSIONS

The pattern of excretion and concentrations of the hLH beta cf is significantly different between premenopausal and postmenopausal women. Perimenopausal women exhibited intermediate changes. The capability to measure this type of stable urinary metabolite as a reflection of changes in dynamics of its parent circulating hormone offers new possibilities in the development and application of large-scale testing that does not require blood sampling.

Differential response to antidepressants in women with premenstrual syndrome/premenstrual dysphoric disorder: a randomized controlled trial

BACKGROUND

Studies show that selective serotonin reuptake inhibitors are effective for severe premenstrual syndrome and premenstrual dysphoric disorder. This study compares the efficacy of a selective serotonin reuptake inhibitor with that of a tricyclic antidepressant to determine whether efficacy for premenstrual syndrome/premenstrual dysphoric disorder is a general or more serotonergic effect of antidepressants.

METHODS

After 3 screening months, 189 subjects were randomized to sertraline hydrochloride, desipramine hydrochloride, or placebo for 3 months of double-blind treatment. The flexible dosage range was 50 to 150 mg/d. The outcome measures included the Penn Daily Symptom Report (DSR), the Hamilton Depression Rating Scale, the Clinical Global Impressions-Severity Scale, the Quality of Life Scale, and Patient Global Ratings of Functioning and Improvement. Analyses included all subjects with treatment data, with the last observation carried forward.

RESULTS

Sertraline was significantly more effective than placebo or desipramine; desipramine was not better than placebo (F2,163 = 12.47, P<.001). All DSR factors were more improved with sertraline compared with desipramine and placebo; the factors for mood (P<.001) and pain (P = .05) were significant, and the results of all outcome measures were consistent. A history of depression, postmenstrual symptom levels, and other diagnostic variables added individually as covariates did not alter the treatment results. At end point analysis, DSR symptoms had decreased by more than 50% in 40 subjects (65%) in the sertraline group, 18 subjects (36%) in the desipramine group, and 16 subjects (29%) in the placebo group (P<.001).

CONCLUSIONS

The comparison of 2 classes of antidepressants strongly favored the serotonergic drug, which effectively reduced symptoms and improved functioning and was well tolerated by women with severe premenstrual syndrome. A history of depression did not alter the treatment results.

Characteristics of placebo responses in medical treatment of premenstrual syndrome

OBJECTIVE

This study characterizes the responses to placebo medication of patients with premenstrual syndrome (PMS) who were randomly assigned in controlled treatment trials. Possible predictors of placebo response were also examined.

METHOD

Subjects from two randomized controlled trials were pooled. The 101 subjects met defined criteria for severe PMS, remained eligible after 1 month of single-blind placebo lead-in treatment, and were randomly assigned to 3 months of double-blind placebo treatment. Improvement in the current study was defined as a decrease of at least 50% in premenstrual symptom score from the pretreatment baseline.

RESULTS

At endpoint, 20 (20%) of the placebo-treated subjects showed sustained improvement, 18 of these in at least 3 of the 4 months of placebo medication. Another 42% of subjects partially improved, and 39% were clearly unimproved throughout the study period.

CONCLUSIONS

Some patients with severe PMS experience significant and sustained improvement with placebo medication, but the majority report only partial or no improvement. Patients who sustain improvement for at least 2 consecutive months are likely to remain improved, indicating the importance of nondrug factors in clinical care.

Full- or half-cycle treatment of severe premenstrual syndrome with a serotonergic antidepressant

Evidence that serotonergic antidepressants are effective for treating premenstrual syndrome (PMS) raises the question of whether dosing only in the symptomatic premenstrual phase is effective for this disorder. This preliminary randomized, double-blind study compared the responses to half-cycle or full-cycle dosing of sertraline in 31 patients who completed a preceding double-blind, short-term treatment trial. The subjects fulfilled criteria for severe PMS when they entered the preceding controlled trial. At the end of the short-term treatment trial, the double-blind was not broken; both improved and unimproved subjects were randomized in a double-blind fashion to receive either full-cycle or half-cycle sertraline in the 3-month extension study. Results showed that the total premenstrual scores from the Penn Daily Symptom Report (DSR) were lower in the half-cycle dosing group in each of the 3 treatment months but did not differ with statistical significance from the full-cycle dosing group. Further analysis of the 17 DSR items showed that mood swings, nervous tension, feeling out of control, and confusion were significantly lower (p < 0.05) at endpoint in the half-cycle dosing group. Overall, subjects who improved in prior treatment remained improved; approximately half the subjects who were unimproved at entry into the extension study improved, regardless of the dosing regimen. The results add support to other preliminary reports of efficacy of serotonergic antidepressants administered premenstrually and indicate the clinical importance of determining an optimal dose/benefit ratio of serotonergic antidepressants for PMS patients.

Racial differences in menopause information and the experience of hot flashes

OBJECTIVE

To compare the prevalence of hot flashes and health education regarding menopause in African-American and white American women in the late reproductive years.

DESIGN

Cross-sectional study.

SETTING

Population-based sample recruited through random digit dialing.

PARTICIPANTS

The sample was 436 women between the ages of 35 and 48 years with regular menses. Half the sample was African American and half was white American.

MAIN RESULTS

African-American women (53%) were more likely than white American women (29%) to have experienced hot flashes (p < .001). The difference remained after adjustment for body-mass index, education, menstrual cycle characteristics, and gynecologic and medical history. Despite the high prevalence of symptoms, few women had discussed menopausal management with their physicians. For white women the media were the primary source of menopause-related information, whereas African-American women reported that their family was the primary source of information.

CONCLUSIONS

These results indicate that hot flashes occur commonly among women in their thirties and forties who have regular menstrual cycles and that the prevalence of hot flashes appears to differ by race. Studies should be designed to evaluate the hormonal and physiologic implications of these symptoms among women in their late reproductive years. Few of these women had discussed menopause with their physicians. Given the differences in sources of information about menopause, development of culture-specific health education programs should be considered.

Premenstrual syndromes

Premenstrual syndromes (PMS) are a group of menstrually related, chronic, cyclical disorders manifested by emotional and physical symptoms in the second half of the menstrual cycle. A diagnosis of PMS is based on the timing and symptom pattern observed in daily symptom reports maintained by the patient. The etiology is unknown but is believed to involve genetic and dynamically evolving vulnerability, reproductive hormones, and neurotransmitters, as well as other brain processes. Effective medications have been identified for acute hormonal and symptomatic treatment of the disorder, but the time course and frequency of relapse and recurrence remain poorly understood. Further studies of PMS in all areas--etiology, pathobiology, diagnosis, course of illness, and treatment efficacy--are needed to increase the body of information about the menstrual cycle's effects on women's health and mood disorders.

Premenstrual syndrome: current perspectives on treatment and etiology

In the past year, randomized controlled clinical trials of treatments for clearly diagnosed premenstrual syndrome reported efficacy for serotonergic antidepressants and a gonadotropin-releasing hormone agonist. Preliminary data suggested efficacy for spironolactone and a carbohydraterich beverage. Several neuroendocrine studies have contributed to a growing list of findings that suggest an underlying neurobiological vulnerability in premenstrual syndrome.

Ovarian aging and hormone replacement therapy. Hormonal levels, symptoms, and attitudes of African-American and white women

OBJECTIVES

To characterize reproductive hormone levels, symptoms, and attitudes related to menopause among healthy, menstruating white and African-American women aged 44 to 49 years.

DESIGN

Pilot study; cross-sectional survey.

SETTING

Community-based convenience sample of women in the Philadelphia metropolitan area.

PARTICIPANTS

Thirty-three African-American and 35 white women.

MEASUREMENTS

The survey instrument collected demographic data, medical and reproductive history, health practices and behaviors. It included previously validated function, depression, and quality-of-life instruments, and a Menopause Attitude Scale that included two factors, attitudes toward the menopause and attitudes toward medical therapy. Anthropometric measurements were taken at enrollment, and reproductive hormones and daily symptom logs were followed over two menstrual cycles.

MAIN RESULTS

The two groups were comparable in mean age (African-American 46.2 years, white 46.9 years). Serum levels of estradiol, follicle-stimulating hormone, dihydroepiandrosterone-sulfate, and progesterone were comparable. Symptoms were similar in type and frequency. However, the African-American women had significantly more positive attitudes toward menopause, were more likely to rely on family for information about menopause, and were less likely to have been recommended hormone replacement therapy by their physicians. A majority of women in each group expressed satisfaction with the care they had received.

CONCLUSIONS

Perimenopausal African-American and white women have different expectations of menopause and the role of medical care in menopause. This bears directly on women's acceptance of hormone replacement therapy. Conclusions are limited by the small sample size and convenience nature of the study population: further work with larger samples is needed to confirm these apparent differences.

Gonadotropin-releasing hormone agonist in the treatment of premenstrual symptoms with and without ongoing dysphoria: a controlled study

Gonadotropin-releasing hormone (GnRH) agonists have been shown to reduce symptoms of premenstrual syndrome (PMS). This randomized, placebo-controlled study examined the efficacy of the GnRH agonist, leuprolide acetate depot, in a clearly defined PMS sample versus women with premenstrual symptoms in combination with dysphoric symptoms throughout the cycle, termed the premenstrual exacerbation (PME) group. Evaluation included the Structured Clinical Interview for DSM-III-R, administered in the follicular phase, and the subject Penn Dally Symptoms Report (DSR) maintained throughout the study. Thirty-three eligible women were randomized to double-blind treatment and administered 3.75 mg of depot leuprolide or a placebo once a month for 3 months. The subjects were seen for efficacy evaluations at the end of each cycle. Outcome measures were the DSRs and the 17-item Hamilton Depression Rating Scale (HAM-D17). The PMS leuprolide subjects improved significantly compared with the PMS placebo and PME leuprolide groups. The PME leuprolide group, who had dysphoric symptoms throughout the cycle, did not improve. Depression symptoms were at clinical levels premenstrually in the PMS and PME groups; following treatment they remitted in the PMS group but not in the PME leuprolide subjects. Efficacy did not occur until after several months of leuprolide treatment, but there was no evidence that PMS symptoms worsened with the onset of treatment. These results replicate the findings in our preliminary open-label study. Leuprolide reduced PMS symptoms to minimal levels where symptoms were limited to the luteal phase. Leuprolide was not effective for women with ongoing dysphoric symptoms, suggesting that premenstrual depression may have mechanisms different from those of other dysphoric mood disorders.

Reliability and validity of a daily diary for premenstrual syndrome

Daily ratings of symptoms are essential to confirm a diagnosis of premenstrual syndrome (PMS). The 17-item Daily Symptom Report (DSR) is relatively brief and appropriate for clinical and primary care settings. We report the reliability, factor structure and relationships with other standard mood measures of the DSR as a measure of PMS. The sample includes 170 women who sought medical treatment for severe PMS and a non-clinical comparison group of 54 healthy women in the same age range. Cronbach's coefficient alpha was 0.92 for the premenstrual DSR scores, indicating very high internal consistency for the 17 symptoms. Factor analysis yielded four factors describing mood, behavioral items, pain, and physical symptoms. In the PMS sample, there were moderate correlations between the DSR and the Hamilton Rating Scale for Depression, the Profile of Mood States, and the Premenstrual Assessment Form. The moderate correlations of the DSR with other standard symptom measures add to the evidence that PMS overlaps with other mood disorders at the premenstrual time but is not simply a brief depression or a truncated anxiety disorder.

Fluvoxamine for premenstrual dysphoric disorder: a pilot study

BACKGROUND

Serotonergic agents appear to be effective treatments for premenstrual symptoms in a number of small trials. The purpose of this open-label treatment study was to collect pilot information on the efficacy of fluvoxamine for premenstrual dysphoric disorder (PDD).

METHOD

Twelve women who sought medical treatment for premenstrual symptoms were evaluated. The main outcome measure was the premenstrual score from daily symptom reports (DSRs) maintained by the subjects. After a 2-month screening period, 10 subjects who met DSM-IV criteria for PDD were treated with fluvoxamine taken daily for two menstrual cycles. The mean dose at 4 weeks was 85 mg/day; at 8 weeks, all subjects took 100 mg/day.

RESULTS

The mean premenstrual DSR scores improved at 4 weeks from the pretreatment baseline (paired t test, p < .0008) and remained improved at 8 weeks at approximately the same level (p < .003). Symptoms with the greatest improvement (p < .003, significant with the Bonferroni adjustment) were irritability, anxiety, feeling out of control, and decreased interest in usual activity. Sixty percent (6/10) of the subjects reported at least a 50% reduction in the DSR scores, a conservative clinical definition of improvement. The mean premenstrual Hamilton Rating Scale for Depression scores decreased from 19 at the pretreatment baseline to 9 at the 4-week evaluation. The main side effects were insomnia (N = 6), fatigue (N = 4), dry mouth (N = 4), and nausea (N = 3) and were generally mild and transient.

CONCLUSION

These promising pilot data show the importance of a controlled trial over a longer time period to provide definitive information on the efficacy of fluvoxamine for premenstrual dysphoric disorder.

Sertraline versus desipramine in the treatment of premenstrual syndrome: an open-label trial

BACKGROUND

Antidepressant medications have appeared to be effective treatments for premenstrual syndrome (PMS) in several small trials. This open-label study examined the efficacy of and tolerance for a new serotonergic antidepressant compared with a traditional tricyclic antidepressant in PMS treatment.

METHOD

For two menstrual cycles in women meeting well-defined criteria for PMS, an open-label comparison of the serotonin selective sertraline (N = 17) and the noradrenergic desipramine (N = 15) was performed. Dose was flexible, with a mean dose in the second cycle of 87 mg/day for sertraline and 110 mg/day for desipramine. Outcome measures were the premenstrual daily symptom report (DSR) scores and the Hamilton Rating Scale for Depression (HAM-D).

RESULTS

Sertraline and desipramine reduced depressive symptoms as assessed by the HAM-D, both achieving similar reductions in the HAM-D scores. Reduction of total premenstrual symptoms as assessed by the DSR score was observably greater with sertraline, but the difference compared with desipramine was not statistically significant in this small sample. Subjects were more likely to perceive desipramine side effects as intolerable; 4 of the 15 desipramine-treated subjects discontinued compared with none in the sertraline group. Subjects who were previously treated in a PMS program without good therapeutic response were less likely to respond to either medication, suggesting a treatment-resistant group.

CONCLUSION

Sertraline and possibly desipramine appear to be effective treatments for PMS. Sertraline was better tolerated, resulting in greater patient acceptance. A placebo-controlled trial in which subjects are randomly assigned to the medication is clearly needed to support or refute these preliminary findings.

A clinician's guide to the premenstrual syndrome

Many women have menstrual symptoms, but relatively few have severe PMS. PMS is a well-defined premenstrual cluster of predominantly affective symptoms that disrupt a woman's daily functioning. PMS is diagnosed with prospective charting of symptoms and should be differentiated from nondisruptive menstrual symptoms, major affective disorders, and other common medical and gynecologic conditions. Most women with PMS can be helped. The serotonin reuptake inhibitors are becoming the first line of therapy for PMS because they are effective, easily tolerated, and free of major side effects. There is also evidence supporting the role of other antidepressants, anxiolytics, and GnRH agonists in the treatment of PMS. Although increasing control of one's life, promoting a healthy diet, the avoidance of salt and caffeine, vitamin supplementation, and exercise have not been proved as effective treatment for PMS, they should be promoted for their obvious general health benefits. No one treatment fits the heterogeneous PMS population. A trial of medication should be continued for two or three menstrual cycles with appropriate dose adjustments. If relief is not sufficient, other agents or other treatments should be initiated.

Personality factors in women with premenstrual syndrome

The recently developed Tridimensional Personality Questionnaire (TPQ) was used to examine personality correlates in women diagnosed with premenstrual syndrome (PMS). The hypotheses were that the TPQ scores, specifically harm avoidance (HA), would be higher in PMS subjects than in the general population but lower than in depressed populations because major mood disorder is an exclusion from the PMS diagnosis; harm avoidance would have the strongest association with PMS, but other TPQ factors might characterize nondysphoric subgroups in the PMS population. The sample included 157 women who sought medical treatment and met clearly defined criteria for PMS. Two comparison groups of age-matched women with major depression (MDD, N = 20) and premenstrual exacerbation of major depression (MDD + PMS, N = 24) were also evaluated. TPQ scores were significantly higher for PMS subjects on all three dimensions compared with external normative TPQ data. The TPQ dimensions of HA and novelty seeking (NS) were modestly correlated with the premenstrual symptom scores. The HA dimension correlated with premenstrual depression and physical aches; high NS scores correlated with premenstrual food cravings, headache, and mood swings. As hypothesized, the HA scores were significantly higher in the comparison groups diagnosed with major depression; the NS and reward dependence (RD) dimensions did not differ between the PMS and MDD groups. PMS was associated with only modest nonnormative personality correlates, as assessed by the TPQ. Elevations of the HA and NS dimensions were associated with a tendency for the PMS to present with specific symptom patterns: depressive symptoms for the HA factor and food cravings and mood swings for the NS factor. Further research employing other assessment methods is needed to confirm these findings.

A double-blind trial of oral progesterone, alprazolam, and placebo in treatment of severe premenstrual syndrome

OBJECTIVE

To determine the effectiveness of oral micronized progesterone, alprazolam, and placebo in premenstrual syndrome (PMS) treatment and the effect of clinical contact on treatment responses.

DESIGN

Randomized, double-blind, placebo-controlled 3-month parallel treatment arms with flexible dosage and with the length of clinical contact randomized within each treatment group.

SETTING

University hospital PMS medical treatment outpatient program in obstetrics/gynecology department.

SUBJECTS

Among volunteers for PMS treatment, 444 were evaluated and 185 meeting defined PMS criteria were randomized to treatment; treatment data are available for 170. There were no medical withdrawals for adverse events.

INTERVENTION

A double-blinded protocol in which 300 mg of oral micronized progesterone, 0.25 mg of alprazolam, or placebo was administered four times a day from day 18 of the menstrual cycle through day 2 of the next cycle, including taper. The mean daily dose at the third treatment was 1760 mg of progesterone or 1.5 mg of alprazolam. Subjects were randomized to brief (< 20 minutes) or extended (50 minutes) visits.

MAIN OUTCOME MEASURES

Daily symptom report (DSR) scored for total DSR symptoms, four DSR factors.

RESULTS

Alprazolam was significantly better than placebo or progesterone for total premenstrual symptoms and DSR factors of mental function, pain, and mood. Thirty-seven percent of the alprazolam group experienced a 50% reduction in total DSR scores. There were no clinically significant withdrawal symptoms when alprazolam administration was restricted to the luteal phase. Oral micronized progesterone therapy was no better than placebo. Brief vs extended visits had no effect on treatment outcome. Treatment response was associated with severity of premenstrual symptoms at baseline but with no other diagnostic variables.

CONCLUSIONS

Alprazolam has a role in PMS treatment and offers a therapy limited to the luteal phase. Oral micronized progesterone is ineffective for PMS.

Relationships between age and symptom severity among women seeking medical treatment for premenstrual symptoms

Age at the time of seeking treatment for premenstrual symptoms (PMS) was examined in a sample of 332 women who reported severe distress and met criteria for Late Luteal Phase Dysphoric Disorder (LLPDD). The mean age of the sample was 33.1 (+/- 5.3) years. Severity of symptoms decreased with age and was not associated with the duration of symptoms. Depression-related factors were associated with the severity of PMS, and together with the duration of symptoms, were the best discriminators between the younger (ages 20-35) and older (ages 36-44) women in this sample. These data suggest that the years of the late twenties through mid-thirties are the most vulnerable time for distressing PMS and fail to support the clinical premise that PMS worsens with age until menopause. Further longitudinal study should be conducted to confirm and extend these findings.

Daily plasma estradiol and progesterone levels over the menstrual cycle and their relation to premenstrual symptoms

The present study extends a previous report of lower plasma ACTH levels in women with premenstrual syndrome (PMS) compared with asymptomatic controls. Plasma levels of estradiol and progesterone were measured daily in 10 women with confirmed PMS and 8 asymptomatic women. Daily symptom reports were maintained during the same menstrual cycle. Both estradiol and progesterone levels were consistently, but not significantly, higher throughout the cycle in PMS subjects compared with controls. From the follicular to the early luteal phase, estradiol levels were significantly higher in a previously defined PMS subgroup 2 with more severe symptoms throughout the cycle compared with both the less severe PMS subgroup 1 and controls. Progesterone levels were significantly and positively correlated with PMS symptoms along the entire menstrual cycle, preceding the symptoms by 5-7 days. These preliminary results provide support for the hypothesis that the presence of progesterone at early luteal phase levels is required for PMS symptoms to occur.

Nefazodone in the treatment of premenstrual syndrome: a preliminary study

Nefazodone, a new phenylpiperazine antidepressant agent with serotonin type 2 antagonism and serotonin reuptake inhibition, was evaluated in two patient groups to determine its effectiveness in reducing the symptoms of premenstrual syndrome (PMS). The two studied groups were PMS patients with no coexisting major depression or dysthymia (N = 23) and PMS patients with current major depression or dysthymia, termed the premenstrual exacerbation group (N = 24). The two patient groups received open-label nefazodone for 8 weeks, with optional maintenance at the same dose for up to 1 year. The initial dose was 100 mg, titrated to 600 mg/day, on a twice-daily dosing schedule. Symptoms were assessed by the Hamilton Rating Scale for Depression and by Daily Symptom Ratings. Premenstrual symptoms improved significantly from pretreatment baseline values, with similar improvement for the PMS and premenstrual exacerbation groups. Significantly improvement occurred by the end of the first treated cycle (4 weeks of therapy), at an average dose of 245 (range, 100 to 400) mg, and was maintained thereafter. Nefazodone was well tolerated, side effects were often transient, and the most common were nausea and headache. Forty-seven of 54 patients completed 2 months of therapy, with a mean daily nefazodone dose of 319 mg at the 2-month point. A placebo-controlled study should be conducted to confirm and extend these promising preliminary findings.

Anxiolytic metabolites of progesterone: correlation with mood and performance measures following oral progesterone administration to healthy female volunteers

Progesterone is readily reduced in humans to its A-ring metabolites, allopregnanolone (3 alpha-hydroxy-5 alpha-pregnan-20-one) and pregnanolone (3 alpha-hydroxy-5 beta-pregnan-20-one). The latter have been reported to have anxiolytic, hypnotic and anesthetic actions when administered to laboratory animals and (or) humans. Consequently, we measured allopregnanolone and pregnanolone in 18 healthy females, ages 18-25, at the time of peak plasma progesterone following an oral dose of micronized progesterone (1,200 mg) in a double-blind, placebo-controlled study. The plasma levels of the parent steroid and metabolites were compared with changes in mood, cognition, and motor performance following progesterone administration. We observed good correlations between plasma progesterone and plasma allopregnanolone (r = 0.85), plasma pregnanolone (r = 0.81) and the combined metabolites (r = 0.92). Plasma allopregnanolone was significantly correlated with measures of fatigue, confusion and immediate recall, and these correlation coefficients were somewhat greater than those for plasma progesterone and these same behavioral measures. Significant changes in fatigue, delayed verbal recall and symbol copying were experienced by subjects who achieved high levels (> or = 95.55 nmol/l) of these anxiolytic metabolites, while those with lower metabolite levels reported no negative effects. These data suggest that allopregnanolone and pregnanolone may contribute to or mediate the observed behavioral effects of progesterone.

Preliminary evidence for plasma adrenocorticotropin levels as biological correlates of premenstrual symptoms

Premenstrual syndrome (PMS) is a menstrual cycle-related disorder of mood and behavior with unknown etiology and lack of evidence of endocrine imbalances. The absence of menstrual cyclicity eliminates PMS symptoms, and cyclic gonadal changes appear necessary but not sufficient cause for behavioral symptoms in predisposed women. As there are many depressive symptoms in PMS, we focused on the neuroendocrine characteristics of depression, primarily hypothalamic-pituitary-adrenal hyperactivity, and investigated plasma adrenocorticotropin (ACTH) and cortisol levels in the menstrual cycle. Blood samples were drawn daily from ten patients with PMS and eight asymptomatic control subjects who also reported symptoms daily throughout one menstrual cycle. The ACTH levels were significantly lower in patients with PMS compared to control subjects in the luteal phase. Two PMS subgroups were identified by cluster analysis applied to symptom scores. Plasma ACTH levels of PMS Cluster 1 subjects were significantly lower compared to controls. The ACTH levels of PMS Cluster 2 subjects were nearly identical to controls. These preliminary results suggest distinct hormonal subgroups in the heterogeneous PMS population and support further study of ACTH as a biological correlate of PMS.
