A double-blind controlled study of the effect of piperazine estrone sulfate on sleep, depression, anxiety, and hot flushes was conducted in 34 perimenopausal women aged 45-55. 1/2 of the group received placebo for 6 weeks, then piperazine estrone sulfate (1.5 mg twice daily) for 8 weeks, while 1/2 remained on placebo throughout. Sleep was recorded electrophysiologically every week after adaptation and baseline readings. Mood and anxiety were rated daily by means of visual analogue scales. Hot flushes were counted daily. Observer rating scales of anxiety and depression were completed at the beginning and end of the baseline placebo period and at the end of the 1st and 2nd treatment month. During the 1st month of active treatment, the amount of intervening wakefulness in the first 6 hours of sleep decreased significantly more in the estrone group than in those on placebo. Between the baseline period and the 2nd treatment month, the estrone group showed a significantly greater decrease in the total amount of wakefulness and in the frequency of awakenings. Their total amount of rapid eye movement sleep increased. Mood and anxiety improved and the number of hot flushes decreased to a similar degree in both groups.

Thirty-seven patients in premature labor with intact membranes were treated as follows. Ritodrine was given as a primary tocolytic agent and magnesium sulfate was added adjunctively when the uterine contractions could not be controlled even when the administration of ritodrine exceeded 250mmg/min (14 of 37 cases) (combination therapy group). Prolongation of pregnancy for more than 48 hours and delivery beyond 37 weeks were achieved in 89% and 68% respectively. These results were more satisfactory than those obtained with the isoxsuprine treated group (122 cases). The incidence of discomfort due to nasal obstruction was low in the ritodrine group, but side effects such as palpitation and hot flush occurred more commonly in the combination group. No life-threatening side effects were observed throughout this study. Twelve out of 37 cases (32%) were delivered before 37 weeks. Neonatal morbidity was more frequent in this group delivered before 33 weeks of gestation. These included respiratory distress, hypotension, hypoglycemia, and hypocalcemia. Moreover, two babies born from mothers treated with ritodrine and magnesium had ileus-like symptoms. These data suggest that this combination therapy is effective as far as the tocolytic purpose is concerned. However, special attention must be paid to adverse maternal and neonatal effects as well.

The vasomotor hot flushes and increased perspiration symptomatic of the menopausal period reflect the adaptation of the body to the lowering of its preset basal temperature resulting from the interference of various central neurotransmitters of suprahypothalamohypophyseal origin. The present double-blind study was conducted to test the efficacy of veralipride, a synthetic antidopaminergic molecule, in eliminating the symptoms of menopause in 50 patients. Results indicated a total elimination of both hot flushes and excessive perspiration in 63% to 80% of the patients treated. The beneficial effects persisted up to 3 months of follow-up. Veralipride significantly increased dehydroepiandrosterone sulfate and estradiol levels. High values of prolactin were found, and some patients showed slight breast discharge; these changes disappeared 48 hours after the drug was stopped.

Previously, we reported that short term administration of a highly potent GnRH agonist (GnRHa) for 1 month to patients with polycystic ovarian disease (PCO) resulted in complete suppression of ovarian steroidogenesis without measurable effects on adrenal steroid production. This new study was designed to evaluate the effects of long term GnRHa administration in PCO patients with respect to their hormone secretion patterns and clinical responses. Eight PCO patients and 10 ovulatory women with endometriosis were treated daily with sc injections of [D-His6-(imBzl]),Pro9-NEt]GnRH (GnRHa; 100 micrograms) for 6 months. Their results were compared to hormone values in 8 women who had undergone bilateral oophorectomies. In response to GnRHa, PCO and ovulatory women had rises of serum LH at 1 month, after which it gradually declined to baseline. In both groups FSH secretion was suppressed throughout treatment. Serum estradiol, estrone, progesterone, 17-hydroxyprogesterone, androstenedione, and testosterone levels markedly decreased to values found in oophorectomized women by 1 month and remained low thereafter. In contrast, serum pregnenolone and 17-hydroxypregnenolone were partially suppressed, and dehydroepiandrosterone, dehydroepiandrosterone sulfate, and cortisol levels did not change. Clinically, hyperplastic endometrial histology in three PCO patients reverted to an inactive pattern, and proliferative endometrium in two other PCO patients became inactive in one and did not change in the other. Regression of proliferative endometrial histology occurred in all ovulatory women. Vaginal bleeding occurred in all women studied during the first month of GnRHa administration, after which all but one PCO patient became amenorrheic. Hot flashes were noted by all ovulatory women and by four of eight PCO patients. All PCO patients noted subjective reduction of skin oiliness, and five had decreased hair growth. We conclude that in premenopausal women: 1) chronic GnRHa administration results in apparently complete persistent suppression of ovarian steroid secretion; 2) adrenal steroid secretion is not influenced directly or indirectly; and 3) its use may be helpful in the treatment of endometrial hyperplasia and ovarian androgen excess in women with PCO.

A randomized clinical trial was designed to determine whether there are clinically demonstrable advantages of phenytoin over magnesium sulfate in preeclamptic patients because of the latter drug's uterine relaxant properties. An intravenous infusion, immediately after randomization, of either phenytoin or magnesium sulfate, with subsequent measurement of serum concentrations and maintenance of therapeutic levels was given to 103 preeclamptic and two eclamptic women. Observed were the rate of cervical dilation during active labor and change in hematocrit between predelivery and 24-hour postdelivery values and the incidence of side effects ascertained by interview. Compared with those receiving magnesium sulfate, patients receiving phenytoin had more rapid cervical dilation (3.3 cm/hr versus 1.5 cm/hr, p = 0.016) and a smaller fall in hematocrit after delivery (-4.7% versus -7.6%, p = 0.034). A significantly lower incidence of hot flushes (15% versus 46%, p < 0.005) and a trend toward less dyspnea and weakness were reported by phenytoin-treated patients. Our phenytoin regimen produced acceptable serum phenytoin levels (10 to 25 micrograms/ml) in 96% of patients.

Exemestane is an irreversible, steroidal, oral aromatase inhibitor under evaluation in postmenopausal women with advanced breast cancer. A phase I study was conducted in 27 postmenopausal patients who were candidates for hormone therapy because they had advanced breast cancer and estrogen receptor-positive or unknown status. Most patients were moderately or heavily pretreated. Cohorts of at least three patients received sequentially escalating daily oral doses of 5-600 mg. The median duration of exemestane treatment was 13 weeks (range: 3-166 weeks). The maximal tolerated dose was not reached because of lack of treatment-related grade 3 or 4 toxicity. The most common adverse events, including those not related to treatment, were mild to moderate headache (44% of patients), dizziness (33%), nausea (33%), hot flushes (30%) and tumor-related pain (30%). There were three complete and four partial responses for an objective response rate of 26% (95% CI: 11.1-46.3%) in the intent-to-treat population; the median duration of response was 74 weeks (95% CI: 48-99 weeks). Exemestane, at the dose of 25 mg, maximally suppressed estradiol, estrone and estrone sulfate serum levels to 13, 5 and 10% of baseline, respectively. Exemestane appears to suppress estrogen, be well tolerated and have antitumor activity in postmenopausal women with advanced breast cancer. A large, safe therapeutic window of up to 600 mg was defined. In view of its safety and estrogen-suppression profiles, the most favorable effects were observed at the 25 mg daily dose.

Recent basic and clinical advances have consolidated the concept of tissue-selective estrogens, i.e. molecules that express different degrees of partial agonist, full agonist or antagonist activity in different tissues or cells. Delta8,9-Dehydroestrone sulfate (delta8,9-DHES) is a conjugated estrogen and a component of conjugated equine estrogens (CEE). It is metabolized in the human in at least a 1:1 ratio to its 17beta form, 17beta-delta8,9-DHES. To evaluate its activity in different clinical and biochemical parameters, a clinical research study was conducted with delta8,9-DHES and estrone sulfate as a comparator in postmenopausal women. Delta8,9-DHES was given orally at a daily dose of 0.125 mg for 12 weeks in a group of 10 women. Two additional groups of women received either estrone sulfate alone (1.25 mg/day) or the combination of delta8,9-DHES and estrone sulfate at the previously specified doses. A significant and consistent suppression of hot flushes (number, severity, and total score) was observed with delta8,9-DHES, reaching more than 95% suppression in all parameters of vasomotor symptoms. This level of activity was equal to that obtained with the much higher dose of estrone sulfate, and it was sustained for the duration of the treatment period (12 weeks). Measurements of a bone resorption marker, i.e. urinary excretion of N-telopeptide, demonstrated that delta8,9-DHES at 8 weeks produced a degree of suppression (40%) similar to that observed with the higher dose of estrone sulfate. Gonadotropin secretion (FSH and LH) was significantly suppressed in women receiving delta8,9-DHES, similar to that observed with estrone sulfate alone or with the combination of the two. Other parameters, such as total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol were not modified significantly, whereas serum globulins (sex hormone-binding globulin and corticosteroid-binding globulin) showed only marginal increases after delta8,9-DHES administration. Taken together with preclinical data, it is found that delta8,9-DHES is an active estrogen with a distinct pharmacological profile that results in significant clinical activity in vasomotor, neuroendocrine (gonadotropin and PRL) and bone preservation parameters, whereas displaying little or no efficacy, at the dose tested, on other peripheral parameters normally affected by estrogens. Collectively, this information supports the concept that delta8,9-DHES is an integral component of CEE, with distinct tissue selectivity contributing to the CEE's overall clinical activity, and places this estrogen as a distinct member of a novel class of centrally active molecules with unique peripheral tissue selectivity.

The study aim was to test the relationship between gendered personality dispositions (GPD), sex hormones, and vasomotor complaints in the menopausal transition. Fifty-seven healthy women (mean age 51.1 years, standard deviation 2.0) were drawn from a population registry. At enrollment all women were menstruating regularly, and all women reached menopause in the course of the study. Questionnaire data and blood samples were collected once a year over a period of five years. GPD scores (based on the Bem Sex-Role Inventory, BSRI), frequencies of hot flushes and hormone data (estradiol, follicle-stimulating hormone, luteinizing hormone, testosterone, androstendione and dehydroepiandrostendione sulfate) were determined. Subjects were placed into four categories based on the BSRI: masculine, feminine, androgynous and undifferentiated. GPD did not change during the menopausal transition. Testosterone and androstendione were related to GPD in that testosterone and androstendione were higher in the sex typed categories (masculine and feminine) than in the non sex-typed categories (androgynous and undifferentiated). GPD are related both to androgens and to vasomotor complaints such as hot flushes during the menopausal transition, but the mechanisms of these relationships are not known.
