Anno T, Kawasaki F, Shigemoto R, Irie S, Mune T, Kaku K, Kaneto H. Alteration of ACTH and Cortisol Levels After Estradiol Valerate Treatment in a Male Subject With Gender Dysphoria: A Case Report. Front Endocrinol (Lausanne) 2019; 10:751. [PMID: 31827460 PMCID: PMC6849494 DOI: 10.3389/fendo.2019.00751] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Accepted: 10/16/2019] [Indexed: 11/29/2022] Open
Abstract
Background: The number of subjects with gender dysphoria has been increasing. In general, male-to-female transsexual subjects are treated with estradiol valerate therapy. In this report, we showed the time course of ACTH and cortisol levels after estradiol valerate injection in a male subject with gender dysphoria. It seemed that alteration of estradiol levels influenced ACTH and cortisol levels via some pathway. Case presentation: A 31-year-old man with estradiol valerate therapy for gender dysphoria was referred due to an elevation of serum cortisol levels. She started hormone therapy at 26 years old. Her laboratory analyses showed an elevation of plasma ACTH and cortisol levels. There were no remarkable changes in the adrenal gland and pituitary gland. Her estradiol levels were elevated 7 days after estradiol valerate injection, but they were not detected 18 days after such treatment. Interestingly, plasma ACTH and serum cortisol levels were moderately decreased 7 days after estradiol valerate injection, but both were markedly elevated 18 days after such treatment. Conclusions: We should bear in mind the possibility of elevation in plasma ACTH and serum cortisol levels when we start estradiol valerate injection in subjects with gender dysphoria. In addition, we may need to check ACTH and cortisol levels when we use estrogen replacement therapy for a long period of time in subjects with gender dysphoria.

Abstract
As a central player of the hypothalamic-pituitary-adrenal (HPA) axis, the corticotropin -releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) determine the state of HPA axis and play a key role in stress response. Evidence supports that during stress response the transcription and expression of CRH was finely tuned, which involved cis-element-transcriptional factor (TF) interactions and epigenetic mechanisms. Here we reviewed recent progress in CRH transcription regulation from DNA methylation to classic TFs regulation, in which a number of paired receptors were involved. The imbalance of multiple paired receptors in regulating the activity of CRH neurons indicates a possible molecular network mechanisms underlying depression etiology and directs novel therapeutic strategies of depression in the future.

Abstract
CONCLUSIONS An unexpected rapid hearing decline remained after the 10-year follow up, similar to the hearing decline in 70-year-old women in reference materials. No clear changes concerning hearing in the peri- and postmenopausal period were noted. OBJECTIVE To assess whether hearing decline correlates with menopause and/or cortisol blood levels. METHODS A prospective individual longitudinal study of peri-menopausal women followed for 10 years was performed at baseline, and after 2, 7 and 10 years, respectively. With a starting age of around 51 years, 100 women remained in the study after 10 years. Pure-tone audiometry and cortisol blood testing were performed at all visits. RESULTS A continuous hearing decline, at all frequencies, was found during the follow-up time. The rate of decline during the menopausal period was higher than compared with reference materials for the same age group. The correlation with time for menopause is most apparent at 1 and 3 kHz where the hearing decline is more rapid after menopause than before. Serum cortisol levels did not correlate with rate of hearing decline.

Abstract
While stress activates the hypothalamic-pituitary-adrenal (HPA) axis, it suppresses the hypothalamic-pituitary-gonadal (HPG) axis. Corticotropin-releasing factor (CRF) is a major regulatory peptide in the HPA axis during stress. Urocortin 1 (Ucn1), a member of the CRF family of peptides, has a variety of physiological functions and both CRF and Ucn1 contribute to the stress response via G protein-coupled seven transmembrane receptors. Ucn2 and Ucn3, which belong to a separate paralogous lineage from CRF, are highly selective for the CRF type 2 receptor (CRF(2) receptor). The HPA and HPG axes interact with each other, and gonadal function and reproduction are suppressed in response to various stressors. In this review, we focus on the regulation of gonadotropins by CRF and Ucn2 in pituitary gonadotrophs and of gonadotropin-releasing hormone (GnRH) via CRF receptors in the hypothalamus. In corticotrophs, stress-induced increases in CRF stimulate Ucn2 production, which leads to the inhibition of gonadotropin secretion via the CRF(2) receptor in the pituitary. GnRH in the hypothalamus is regulated by a variety of stress conditions. CRF is also involved in the suppression of the HPG axis, especially the GnRH pulse generator, via CRF receptors in the hypothalamus. Thus, complicated regulation of GnRH in the hypothalamus and gonadotropins in the pituitary via CRF receptors contributes to stress responses and adaptation of gonadal functions.

Abstract
In temperate zones, day length changes markedly across the year, and in many mammals these photoperiodic variations are associated with physiological adaptations. However, the influence of this environmental variable on human behavior and physiology is less clear, and the potential underlying mechanisms are unknown. To address this issue, we examined the effect of changing photoperiods on adrenal gland function in ovariectomized female rhesus macaques (Macaca mulatta), both in terms of steroid hormone output and in terms of gene expression. The animals were sequentially exposed to the following lighting regimens, which were designed to simulate photoperiods associated with winter, spring/autumn and summer respectively: 8 h light:16 h darkness (short days), 12 h light:12 h darkness and 16 h light:8 h darkness (long days). Remote 24-h serial blood sampling failed to disclose any effect of photoperiod on mean or peak plasma levels of cortisol or dehydroepiandrosterone sulfate. However, there was a marked phase-advancement of both hormonal rhythms in short days, which was reflected as a similar phase-advancement of the daily motor activity rhythm. Gene microarray analysis of the adrenal gland transcriptome revealed photoperiod-induced differences in the expression of genes associated with homeostatic functions, including: development, lipid synthesis and metabolism, and immune function. Taken together, the results indicate that in primates, both circadian adrenal physiology and gene expression are influenced by seasonal changes in day length, which may have implications for adrenal-regulated physiology and behavior.

Abstract
The hypothalamic-pituitary-adrenal (HPA) axis is activated under various stressors. Corticotropin-releasing factor (CRF) plays a central role in controlling stress response, and regulating the HPA axis. CRF, produced in the hypothalamic paraventricular nucleus (PVN), stimulates adrenocorticotropic hormone (ACTH) production via CRF receptor type 1 (CRF(1) receptor) from the corticotrophs of the anterior pituitary (AP). Cyclic AMP (cAMP)-protein kinase A (PKA) pathway takes a main role in stimulating CRF gene transcription. Forskolin and pituitary adenylate cyclase-activating polypeptide (PACAP) stimulate adenylate cyclase, intracellular cAMP production, and then CRF and arginine vasopressin (AVP) gene expression in hypothalamic 4B cells. Interleukin (IL)-6, produced in the PVN, both directly and indirectly stimulates CRF and AVP gene expression. Estradiol may enhance the activation of CRF gene expression in response to stress. The HPA axis is regulated by a negative feedback mechanism, because glucocorticoids inhibit both CRF production in the hypothalamic PVN and ACTH production in the pituitary. Hypothalamic parvocellular neurons in the PVN are known to express glucocorticoid receptors, and glucocorticoids are able to regulate CRF gene transcription and expression levels directly in the PVN. Glucocorticoids-dependent repression of cAMP-stimulated CRF promoter activity is mainly localized to promoter sequences between -278 and -233 bp. Both negative glucocorticoid regulatory element (nGRE) and serum response element (SRE) are involved in the repression of the CRF gene in the hypothalamic cells.

Abstract
UNLABELLED Dehydroepiandrosterone (DHEA) may be useful in the treatment of postmenopausal osteoporosis (PMO). Our present study has found the preferable stimulatory effect of DHEA on bone, in contrast to the proliferative effects of estradiol (E2) on the endometrium and the uterus, which suggests that DHEA has greater potential clinical value than estrogens in prophylaxis and therapeutics for PMO. INTRODUCTION A series of findings raise the possibility that DHEA may be useful in the treatment of PMO. Our present study thus aimed at the differential effects of DHEA and E2 on bone and the uterus in ovariectomized mice as well as the involvement of aromatase, ERalpha, ERbeta, and AR in the effects. METHODS Ovariectomized and sham BALB/c mice were given daily treatment with either DHEA or E2 for three months, respectively. Bone mineral density was determined by DEXA after the last treatment. Mice were necropsied in 3 months after the treatment to analyze the ultrastructure of their femur osteoblasts (OBs) with a transmission electron microscope (TEM); DHEA, DHEA sulfate (DHEAS) and E2 levels were assayed by EIA; production in vitro of E2 in the uterus or tibia was assayed to evaluate the profile of P450arom activity; ERalpha and ERbeta mRNA levels in the uterus and tibia were determined by real-time PCR. The primary murine OBs were treated with DHEA and E2, respectively for 72 h. Real-time polymerase chain reaction (PCR) and western blot were carried out to evaluate aromatase, ERalpha, ERbeta and AR expression in OBs. RESULTS Both DHEA and E2 significantly improved BMD and OB ultrastructure; E2 but not DHEA has significantly increased uterus wet weight, endometrium epithelial and gland thickness. Dehydroepiandrosterone not only increased serum, femoral DHEA, DHEAS and E2 concentration, but also increased uterine DHEA and DHEAS other than E2 concentration in site, while E2 only increased serum, uterine and femoral E2 concentration, but failed to alter the concentrations of DHEA and DHEAS. Moreover, DHEA significantly increased tibia P450arom enzyme activity, while E2 increased uterine and tibia aromatase activity. Furthermore, DHEA increased uterine ERbeta and ERalpha, and ERbeta transcription in the tibia, while E2 increased ERalpha transcription in the uterus and tibia. Dehydroepiandrosterone increased aromatase, ERalpha, ERbeta and AR expression in OBs, and increased significantly, but E2 apparently decreased the ratio of ERbeta/ERalpha. CONCLUSIONS Although both DHEA and E2 augment BMD, the proliferative effects of E2 on the endometrium and uterus reflect the different modes of action on bone and the uterus, indicating that the preferable stimulatory effect of DHEA on bone appears to the more potential clinical values than estrogens in prophylaxis and therapeutics for PMO. But applicability of the findings from rodents in humans needs further study.

Abstract
OBJECTIVES The purpose of this study was to compare the effects of 3 months of estrogen replacement therapy, estrogen plus progesterone replacement therapy and a placebo, on the resting cortisol and interleukin-6 (IL-6) levels in post-menopausal women. METHODS Forty-three women were randomised to one of three treatment arms: estradiol 2mg/day (ERT), estradiol 2mg/day plus medroxyprogesterone acetate 5mg/day (HRT), or a placebo that was administered orally for 3 months. RESULTS Cortisol levels showed a significant condition by intervention interaction. Post hoc tests showed that ERT significantly increased cortisol levels after treatment compared to baseline, while in the HRT group a trend toward increased cortisol was found. No changes were observed in IL-6 levels. CONCLUSIONS Estrogen administration elevated cortisol levels, but this effect may be moderated by progestins. IL-6 was not altered by ERT or HRT, future studies should consider the interaction of cortisol increases on change in IL-6 expression.

Abstract
OBJECTIVE Our objective was to study the 24-h profiles of GH, prolactin (PRL), and cortisol concentrations in older postmenopausal and middle-aged premenopausal women, before and after estrogen-progestin treatment (EPT). DESIGN The study was a randomized, placebo-controlled, double-blind trial. GH, PRL, and cortisol were sampled every 20 min for 24 h in 18 postmenopausal (aged 58-70 yr) and 17 premenopausal (aged 45-51 yr) women before and after 6 months of EPT. RESULTS The mean 24-h GH (1.0 vs. 1.8 mU/liter, P = 0.033) and PRL (6.8 vs. 10.0 ng/ml, P = 0.009) concentrations were lower in postmenopausal than in premenopausal women. After EPT, the postmenopausal GH and PRL did not differ from premenopausal baseline levels. Postmenopausal mean 24-h GH (P < 0.001) and PRL (P = 0.002), daytime GH (P < 0.001) and nighttime PRL (P = 0.004) were higher during EPT compared with placebo. Cortisol levels did not differ. Premenopausal mean nighttime PRL (P = 0.026) and cortisol (P = 0.018) were higher during EPT compared with placebo. Postmenopausal PRL and premenopausal GH and PRL concentrations were higher at night than during the day. EPT did not alter this pattern. CONCLUSIONS Menopause was associated with decreased 24-h levels of GH and PRL, which were reversible with EPT. In contrast, cortisol levels were not affected by menopause or EPT. In middle-aged premenopausal women, the studied effects of EPT were limited to nighttime increases of PRL and cortisol.

Abstract
Corticotropin-releasing factor (CRF) is produced in the hypothalamic paraventricular nucleus (PVN) in response to stress and stimulates the release of adrenocorticotropic hormone in the corticotrophs. Estrogens acting centrally are able to modulate the stress responses. In fact, direct estrogenic regulation of CRF gene expression has been demonstrated in various tissues. However, the mechanisms responsible for the actions of estrogens on CRF regulation in the PVN remain undetermined. We investigated whether estradiol (E2) contributes to the regulation of CRF gene and promoter activity in hypothalamic 4B cells. Furthermore, the involvement of E2 in the regulation of interleukin (IL)-6 and its role in hypothalamic 4B cells was explored. We demonstrated the dominant expression of estrogen receptor type beta (ERbeta) and found that a physiologically relevant dose of E2 and an ERbeta agonist stimulated CRF gene transcription in hypothalamic 4B cells. E2 stimulated IL-6 transcriptional activity via ERbeta, and subsequently the levels of IL-6 mRNA and protein. We also found that treatment with IL-6 significantly reduced cell viability. Thus, these data suggest the important effects of E2 on the regulation of CRF gene and IL-6 production via ERbeta in hypothalamic 4B cells.

Abstract
Alterations in central nervous system response to menstrual cycle-related fluctuations in neuroactive steroids are thought to underlie the emergence of negative affect in the luteal phase of the menstrual cycle in women with premenstrual dysphoric disorder (PMDD). Such changes in the neuroendocrine milieu may lead to heightened arousal and response to stress in women with PMDD. Using the acoustic startle paradigm, we sought to determine whether women with PMDD have an accentuated physiologic response to a mildly aversive stimulus during the luteal compared to follicular phase. Further, we also examined the impact of visual affective stimuli on acoustic startle response (ASR) magnitude. During the follicular and luteal phases of the menstrual cycle, acoustic stimuli (103 dB) were delivered to 15 women with PMDD and 14 healthy menstruating women of similar age. After obtaining baseline ASR, the procedure was repeated when subjects viewed pleasant, neutral and unpleasant pictures. There was a significant group by menstrual cycle phase interaction for baseline ASR magnitude, which can be attributed to the heightened startle magnitude in women with PMDD compared to healthy women during the luteal relative to the follicular phase. The direction and degree to which picture viewing modulated the startle magnitude did not vary by group or menstrual cycle phase. These data suggest that menstrual cycle phase has a powerful modulatory effect on physiologic reactivity in women with PMDD but not in healthy women. Physiologic response to affective stimuli appears to be intact in women with PMDD across the menstrual cycle.

Abstract
OBJECTIVE The aim of the present study was to investigate whether there is an association between serum cortisol and work-related stress, as defined by the demand-control model in a longitudinal design. METHODS One hundred ten women aged 47-53 years completed a health questionnaire, including the Swedish version of the Job Content Scale, and participated in a psychological interview at baseline and in a follow-up session 2 years later. Morning blood samples were drawn for analyses of cortisol. RESULTS Multiple stepwise regression analyses and logistic regression analyses showed that work demands and lack of social support were significantly associated with cortisol. CONCLUSIONS The results of this study showed that negative work characteristics in terms of high demands and low social support contributed significantly to the biological stress levels in middle-aged women. Participation in the study may have served as an intervention, increasing the women's awareness and thus improving their health profiles on follow-up.

Abstract
OBJECTIVE To investigate the relationship between serum dehydroepiandrosterone sulfate (DHEAS) concentration and bone mineral density (BMD), lipids, and hormone replacement therapy (HRT) in postmenopausal women. METHODS Two hundred twenty-seven women aged >40 years were admitted to the study and divided into three groups: 61 premenopausal normally menstruating women, 108 postmenopausal women who were not receiving HRT, and 58 postmenopausal women receiving HRT. DHEAS levels and lipid patterns were measured. BMD measurements of the lumbar spine (L1-L4) were performed by dual-energy x-ray absorptiometry (DXA). RESULTS A positive correlation between DHEAS levels and BMD was found in all three groups. A linear regression model was used to assess the effect of age, body mass index (BMI), parity, and BMD of lumbar vertebrae (L1-L4) on changes in the serum level of DHEAS and found that aging and BMD at the spine had a significant association with serum level of DHEAS and only aging after adjustment for age, BMI, parity, and lipid patterns among the three groups. Age (RR 0.80), DHEAS (RR 0.98), and osteoporosis/osteopenia rate (RR 24.94) were also found to be independent influencing factors for HRT use. CONCLUSIONS A positive correlation between DHEAS levels and BMD was found in all three groups. Our study confirms earlier reports that DHEAS levels decrease with age in premenopausal and, especially, postmenopausal women regardless of estrogen treatment. DHEAS levels in postmenopausal women were not associated with atherogenic lipid patterns in the present study.

Copeland JL, Tremblay MS. Effect of HRT on hormone responses to resistance exercise in post-menopausal women. Maturitas 2005; 48:360-71. [PMID: 15283928 DOI: 10.1016/j.maturitas.2003.09.025] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2003] [Revised: 08/26/2003] [Accepted: 09/04/2003] [Indexed: 11/16/2022]
Abstract
PURPOSE The purpose of this study was to evaluate the effect of hormone replacement therapy (HRT) on the acute and chronic hormonal responses to resistance exercise in post-menopausal women. METHODS Thirty-two post-menopausal women were recruited for this study; 16 who were currently using HRT and 16 who were not using HRT. Subjects in both the HRT and NHRT groups were randomly assigned to either a resistance training group (N = 16; 8 HRT and 8 NHRT) or a control group (N = 16; 8 HRT and 8 NHRT). The training group completed a supervised resistance training program three times a week for 12 weeks. To evaluate changes in hormone levels, resting blood samples were drawn at weeks 0, 4, and 13 of the program. In addition, at weeks 0 and 13, post-exercise blood samples were drawn in order to examine the hormone response to an acute bout of resistance exercise. Samples were analyzed for serum growth hormone (GH), insulin-like growth factor-1 (IGF-1), testosterone, estradiol, dehydroepiandrosterone (DHEA), and cortisol. RESULTS There were no significant changes in resting hormone levels between weeks 0, 4, and 13 of the training program. There was a significant week-by-group interaction for DHEA (P < 0.05 ) and cortisol (P < 0.05 ) with the NHRT-training group having a greater post-exercise increase in DHEA and cortisol after training. Overall, the post-exercise GH levels were significantly greater than pre-exercise (P < 0.05 ) or recovery levels (P < 0.01). There were no significant differences between HRT and NHRT groups in the acute hormone response to exercise. CONCLUSION These results indicate that HRT will not have an effect on the acute or chronic hormone response to a recreational resistance training program in post-menopausal women.

Abstract
The goal of this study was to evaluate the long-term adrenocortical effects of premenopausal oral contraceptives (OC) and postmenopausal conjugated equine estrogens (CEE) and soy isoflavones in a female cynomolgus monkey model. Half of the animals received a triphasic OC for a period of 26 months, after which all monkeys were ovariectomized and randomized to one of three diet groups for 36 months: 1). isoflavone-depleted soy protein (control) (n = 54); 2). soy protein with isoflavones (129 mg/d equivalent) (SPI+) (n = 56); or 3). isoflavone-depleted soy protein with CEE (0.625 mg/d equivalent) (n = 59). In the premenopausal phase, OC treatment resulted in significantly higher cortisol (F) and lower dehydroepiandrosterone sulfate, androstenedione, and testosterone relative to intact controls. In the postmenopausal phase, CEE treatment resulted in significantly higher basal F and lower dehydroepiandrosterone sulfate, androstenedione, and testosterone when compared with control and SPI+ diets. Serum F and androgens in the SPI+ group did not differ significantly from the control group. The SPI+ group had significantly lower adrenal weight than either control or CEE groups, and this effect was localized primarily to the zona fasciculata region of the adrenal cortex. These findings suggest that long-term estrogen treatment may contribute to an androgen-deficient and hypercortisolemic state.

Tamoxifen is an estrogen antagonist on gonadotropin secretion and responsiveness of the hypothalamic-pituitary- adrenal axis in female monkeys. Endocrine 2003; 22:305-15. [PMID: 14709804 DOI: 10.1385/endo:22:3:305] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2003] [Revised: 10/23/2003] [Accepted: 10/28/2003] [Indexed: 01/25/2023]
Abstract
The selective estrogen receptor modulator, tamoxifen, effectively slows the progression of estrogen-positive breast cancer and reduces the possibility of this cancer developing in women at high risk. Despite the widespread acceptance of tamoxifen as a therapeutic agent for this disease, its effects on other estrogen-dependent pathways, particularly on neural circuits regulating brain function and peripheral hormone secretion, are poorly understood. The present study, using previously ovariectomized rhesus monkeys, examined the effects of tamoxifen, in both the presence and absence of estradiol replacement, on the reproductive and hypo-thalamic-pituitary-adrenal (HPA) axes. In Experiment 1, monkeys randomly assigned to three groups (n = 8 each) were treated with placebo and either two doses of estradiol, two doses of tamoxifen alone, or two doses of tamoxifen plus high-dose estradiol to assess the effects on negative feedback suppression of luteinizing hormone (LH). Both doses of tamoxifen effectively antagonized the negative feedback efficacy of estradiol on LH secretion. In contrast, neither the low- or high-dose tamoxifen alone had any effect on LH secretion, as concentrations during tamoxifen treatments were indistinguishable from those during placebo. In Experiment 2, females were randomly assigned to one of four treatment groups (placebo, n = 6; estradiol, n = 5; tamoxifen only, n = 5; or tamoxifen plus estradiol, n = 6) to assess the effects on glucocorticoid negative feedback and pituitary and adrenal responsiveness to exogenous corticotropin- releasing hormone (CRH). Tamoxifen also antagonized the facilitating effects of estradiol on basal and CRH-induced ACTH and cortisol secretion. However, this antagonism produced basal and CRH-stimulated cortisol and ACTH concentrations that were lower than placebo-treated females. Interestingly, tamoxifen in the absence of estradiol produced a similar diminution in ACTH and cortisol response. These data suggest that, in the presence of estradiol, tamoxifen not only antagonized estrogenic facilitation of HPA responsivity but also actually attenuated the response compared with the placebo-treatment condition. Taken together, these data indicate that tamoxifen acts as an estrogen antagonist on the neural circuits controlling the neuroendocrine regulation of the hypothalamic-pituitary-ovarian and adrenal axes in ovariectomized macaque females.

Abstract
In an investigation of cortisol secretion in fully mature, ovariectomized cynomolgus monkeys (Macaca fascicularis), we compared monkeys that were given either placebo (OVX, n = 26) or 17beta estradiol (E(2 )) (EST, n = 26) in a daily oral dose. Serum cortisol concentrations were measured prior to the experimental manipulation and 3, 6, 9, and 12 months following initiation of treatment. Pretreatment cortisol values did not differ between groups. Assessment of the treatment period values revealed that cortisol concentrations were significantly higher ( approximately 10%) in the EST than in the OVX monkeys. Cortisol also varied significantly across periods of sampling. This time-dependent variation was attributable to elevations in months 6 and 9 (when daylight was generally long), relative to months 3 and 12 (when daylight was relatively short). The modest stimulatory effect of estrogen on corticosteroid production observed in this study is consistent with what has been seen in women, and contrasts with the more robust effects observed in New World monkeys. The possible relationship between season and cortisol secretion observed here has not been previously described in monkeys.

Abstract
OBJECTIVE To assess the effect of low-dose conjugated equine estrogens (E) on circulating neurotransmitters and the efficacy for the treatment of psychological symptoms. DESIGN Controlled comparative clinical study. SETTING Endocrine Research Unit, Instituto Mexicano del Seguro Social, Mexico. PATIENT(S) Thirty postmenopausal women received conjugated equine E. Ten women acted as a comparison group. INTERVENTION(S) Conjugated equine E, 0.312 mg/day, for 21 days per cycle during six cycles and added chlormadinone acetate, 2 mg/day, for the last 5 days of each cycle. Green scale for climateric women and Blatt-Kupperman Menopausal Index were used for measuring psychological well-being. MAIN OUTCOME MEASURE(S) Serum levels of dopamine (DA), noradrenaline, serotonin, and beta-endorphin were quantified by specific assays at baseline and at the end of treatment. RESULT(S) Low baseline levels of DA, serotonin, and beta-endorphin increased significantly (P<.001) from 181.9 +/- 47.8 pg/mL to 202.9 +/- 32.8 pg/mL (mean +/- SD); from 206.4 +/- 94.2 ng/mL to 279.2 +/- 67.9 ng/mL; from 11.2 +/- 1.8 pmol/L to 13.8 +/- 2.4 pmol/L, respectively, after conjugated equine E. In parallel, augmented baseline noradrenaline levels diminished significantly (P<.05) from 30.2 +/- 4.7 ng/mL to 24.0 +/- 4.7 ng/mL. All neurotransmitter levels had a significant correlation with 17beta-E(2) concentrations at the end of the study. Alleviation of psychological symptoms was observed in all but eight treated women. CONCLUSION(S) Low-dose conjugated equine E associated with periodic administration of chlormadinone acetate elicited favorable changes in neurotransmitters and relieved psychological symptoms.
