Globally, breast cancer is the most common cancer and the second leading cause of cancer-related death among women. Surgery, chemotherapy, hormonal therapy, and radiotherapy are currently available treatment options for breast cancer therapy. However, chemotherapy, hormonal therapy, and radiotherapy are often associated with side effects and multidrug resistance, recurrence, and lack of treatment in metastasis are the major problems in the treatment of breast cancer. Recently, dietary phytochemicals have emerged as advantageous agents for the prevention and therapy of cancer due to their safe nature. Ellagic acid (EA), sulforaphane (SF), and ursolic acid (UA), which are found in widely consumed fruits and vegetables, have been shown to inhibit breast cancer cell proliferation and to induce apoptosis. This review encompasses the role of EA, SF, and UA in the fight against breast cancer. Both in vitro and in vivo effects of these agents are presented.

In trans women (male-to-female transsexual persons), cross-sex hormone therapy is administered to induce feminization. Breast development is an important part of feminization for most trans women. The aim of this study is to assess the effect of cross-sex hormone therapy on breast development in adult trans women. Additionally, we aimed to investigate the benefit or harm of administration of progestogens on breast development. A review of the literature in Embase, Medline, The Cochrane Library, PsycINFO databases, PubMed, and Web of Knowledge until January 2014. Effects of cross-sex hormone therapy and progestogens on breast development in trans women. Only few studies with low quality of evidence addressed these topics. The available evidence suggests that breast development is insufficient for the majority of trans women and that type and dosage of hormonal therapy seem not to have an important role on final breast size. Our knowledge concerning the natural history and effects of different cross-sex hormone therapies on breast development in trans women is extremely sparse and based on low quality of evidence. Current evidence does not provide evidence that progestogens enhance breast development in trans women. Neither do they prove the absence of such an effect. This prevents us from drawing any firm conclusion at this moment and demonstrates the need for further research to clarify these important clinical questions. © 2014 International Society for Sexual Medicine.

Contraceptive Hormone Use and Cardiovascular Disease

2009-01-01

Contraceptive hormones, most commonly prescribed as oral contraceptives (OC), are a widely utilized method to prevent ovulation, implantation and therefore pregnancy. The Women’s Health Initiative demonstrated cardiovascular risk linked to menopausal hormone therapy among women without pre-existing cardiovascular disease, prompting review of the safety, efficacy and side effects of other forms of hormone therapy. A variety of basic science, animal and human data suggest that contraceptive hormones have anti-atheromatous effects, however relatively less is known regarding the impact on atherosclerosis, thrombosis, vasomotion and arrhythmogenesis. Newer generation OC formulations currently in use indicate no increased myocardial infarction (MI) risk for current users, but a persistent increased risk of venous thrombo-embolism (VTE). There are no cardiovascular data available for the newest generation contraceptive hormone formulations, including those that contain newer progestins that lower blood pressure, as well as the non-oral routes (topical and vaginal). Current guidelines indicate that, as with all medication, contraceptive hormones should be selected and initiated by weighing risks and benefits for the individual patient. Women 35 years and older should be assessed for cardiovascular risk factors including hypertension, smoking, diabetes, nephropathy and other vascular diseases including migraines, prior to use. Existing data are mixed with regard to possible protection from OC for atherosclerosis and cardiovascular events; longer-term cardiovascular follow-up of menopausal women with regard to prior OC use, including subgroup information regarding adequacy of ovulatory cycling, the presence of hyperandrogenic conditions, and the presence of prothrombotic genetic disorders is needed to address this important issue.

2007-01-01

Prostate cancer is a common cause of death in men and remains incurable in the metastatic setting. In 2004, 2 landmark trials using docetaxel-based chemotherapy, TAX 327 and SWOG 99-16, showed a survival benefit for the first time in metastatic, hormone-refractory prostate cancer. Current research suggests that several distinct mechanisms of androgen-refractory disease may converge in patients with disease progression on androgen deprivation therapy. These findings have identified several potential targets for therapeutic intervention. Current standard and investigational treatment options for this disease are discussed, including chemotherapy and rapidly evolving therapies in phase II/III trials involving antiangiogenic therapies, signal transduction inhibitors, immunomodulatory agents, and nuclear receptor targets. In light of a growing array of treatment options and an increasingly chronic natural history, this review supports a multidisciplinary care approach to these patients, including medical oncologists, urologists, and radiation oncologists, to optimize survival and quality of life.

Aim To review the current evidence concerning the long-term harmful effects of premature or early menopause, and to discuss some of the clinical implications. Material and methods Narrative review of the literature. Results Women undergoing premature or early menopause, either following bilateral salpingo-oophorectomy or because of primary ovarian insufficiency, experience the early loss of estrogen and other ovarian hormones. The long-term consequences of premature or early menopause include adverse effects on cognition, mood, cardiovascular, bone, and sexual health, as well as an increased risk of early mortality. The use of hormone therapy has been shown to lessen some, although not all of these risks. Therefore, multiple medical societies recommend providing hormone therapy at least until the natural age of menopause. It is important to individualize hormone therapy for women with early estrogen deficiency, and higher dosages may be needed to approximate physiological concentrations found in premenopausal women. It is also important to address the psychological impact of early menopause and to review the options for fertility and the potential need for contraception, if the ovaries are intact. Conclusions Women who undergo premature or early menopause should receive individualized hormone therapy and counseling. PMID:25845383

This review focuses on the effect that cross-gender sex steroid therapy has on metabolic and hormonal parameters. There is an emphasis on those changes that result in significant clinical effects such as the positive effects of the development of secondary sexual characteristics and negative effects such as haemostatic effects and thromboembolism in transwomen or dyslipidaemia in transmen. There is also a description of the current hormonal regimens used at the largest UK gender identity clinic. The overall safety of these treatments in the context of long-term outcome data is reviewed. © The Author(s) 2015.

Use of menopausal hormone therapy and risk of ductal and lobular breast cancer among women 55-74 years of age.

The Women's Health Initiative (WHI) randomized trials found that use of combined estrogen and progestin menopausal hormone therapy (CHT) increases breast cancer risk, but use of unopposed estrogen hormone therapy (EHT) does not. However, several questions regarding the impact of hormone use on risk of different types of breast cancer and what thresholds of use confer elevations in risk remain. We conducted a population-based case-control study among women 55-74 years of age to assess the association between menopausal hormone use and risk of invasive ductal and invasive lobular breast carcinomas. Associations were evaluated using polytomous logistic regression and analyses included 880 ductal cases, 1,027 lobular cases, and 856 controls. Current EHT and CHT use were associated with 1.6-fold [95 % confidence interval (CI): 1.1-2.2] and 2.3-fold (95 % CI: 1.7-3.2) increased risks of lobular breast cancer, respectively, but neither was associated with risk of ductal cancer. Lobular cancer risk was increased after 9 years of EHT use, but after only 3 years of CHT use. Evidence across more than a dozen studies indicates that lobular carcinoma is the type of breast cancer most strongly influenced by menopausal hormones. Here, we characterize what thresholds of duration of use of both EHT and CHT that confer elevations in risk. Despite the rapid decline in hormone therapy use the WHI results were published, study of the hazards associated with these medications remains relevant given the estimated 38 million hormone therapy prescriptions that are still filled in the United States annually.

Thyrotropin-secreting pituitary adenomas: biological and molecular features, diagnosis and therapy.

2008-12-01

Central hyperthyroidism due to a thyrotropin (TSH)-secreting pituitary adenoma is a rare cause of hyperthyroidism, representing 0.5-1.0% of all pituitary adenomas. The etiopathogenesis of TSH-secreting-adenomas is unknown and no definite role for various oncogenes has been proven. Patients with TSH-secreting adenoma usually present with signs and symptoms of hyperthyroidism milder than those in patients with hyperthyroidism of thyroid origin, in addition to symptoms secondary to mass effects of the pituitary tumour. Mixed pituitary tumours co-secrete growth hormone and prolactin. The characteristic biochemical abnormalities are normal or high serum TSH concentrations in the presence of elevated total and/or free thyroid hormones concentrations. Measurement of markers of peripheral thyroid hormone action and dynamic tests may aid in the differential diagnosis with the syndrome of resistance to thyroid hormone. Neuroimaging is fundamental to visualize the pituitary tumor. Therapy of TSH-secreting adenomas can be accomplished by surgery, radiation therapies, and medical treatment with somatostatin analogs or dopamine agonists. Nowadays, and in contrast with the first reports on this rare disease, most patients are well controlled by current therapies.

Hypocalcemia

Fong, Jeremy; Khan, Aliya

2012-01-01

Abstract Objective To provide family physicians with an evidence-based approach to the diagnosis and management of hypocalcemia. Quality of evidence MEDLINE and EMBASE articles from 2000 to 2010 were searched, with a focus on the diagnosis and management of hypocalcemia. Levels of evidence (I to III) were cited where appropriate, with most studies providing level II or III evidence. References of pertinent papers were also searched for relevant articles. Main message Chronic hypocalcemia is commonly due to inadequate levels of parathyroid hormone or vitamin D, or due to resistance to these hormones. Treatment focuses on oral calcium and vitamin D supplements, as well as magnesium if deficiency is present. Treatment can be further intensified with thiazide diuretics, phosphate binders, and a low-salt and low-phosphorus diet when treating hypocalcemia secondary to hypoparathyroidism. Acute and life-threatening calcium deficit requires treatment with intravenous calcium. The current treatment recommendations are largely based on expert clinical opinion and published case reports, as adequately controlled clinical trial data are not currently available. Complications of current therapies for hypoparathyroidism include hypercalciuria, nephrocalcinosis, renal impairment, and soft tissue calcification. Current therapy is limited by serum calcium fluctuations. Although these complications are well recognized, the effects of therapy on overall well-being, mood, cognition, and quality of life, as well as the risk of complications, have not been adequately studied. Conclusion Family physicians play a crucial role in educating patients about the long-term management and complications of hypocalcemia. Currently, management is suboptimal and marked by fluctuations in serum calcium and a lack of approved parathyroid hormone replacement therapy for hypoparathyroidism. PMID:22439169

Is complementary and alternative therapy effective for women in the climacteric period?

PubMed

Kim, Mi Young; Choi, Seung Do; Ryu, Aeli

2015-04-01

Vasomotor symptoms start about 2 years prior to menopause in women who are approaching menopause, and early menopause symptoms appear including emotional disturbance and anxiety, followed by physical changes such as vaginal dryness, urinary incontinence and skin wrinkles. As time progresses, osteoporosis, cardiovascular diseases, and dementia occur consecutively. Hormone therapy is primarily considered for the relief of menopause symptoms in postmenopausal women. However, as hormone replacement has emerged as a therapy that increases the potential risk of thrombosis, cerebral infarction and breast cancer, complementary and alternative medicine has drawn much attention. This study aimed to examine the types and effects of evidence-based complementary and alternative therapies that are currently used.

Pituitary tumors. Current concepts in diagnosis and management.

PubMed Central

Aron, D C; Tyrrell, J B; Wilson, C B

1995-01-01

Diagnostic advances have resulted in earlier and more frequent recognition of pituitary tumors. Pituitary tumors cause problems owing to the hormones they secrete or the effects of an expanding sellar mass--hypopituitarism, visual field abnormalities, and neurologic deficits. Prolactin-secreting tumors (prolactinomas), which cause amenorrhea, galactorrhea, and hypogonadism, constitute the most common type of primary pituitary tumors, followed by growth hormone-secreting tumors, which cause acromegaly, and corticotropin-secreting tumors, which cause Cushing's syndrome. Hypersecretion of thyroid-stimulating hormone, the gonadotrophins, or alpha-subunits is unusual. Nonfunctional tumors currently represent only 10% of all clinically diagnosed pituitary adenomas, and some of these are alpha-subunit-secreting adenomas. Insights into the pathogenesis and biologic behavior of these usually benign tumors have been gained from genetic studies. We review some of the recent advances and salient features of the diagnosis and management of pituitary tumors, including biochemical and radiologic diagnosis, transsphenoidal surgery, radiation therapy, and medical therapy. Each type of lesion requires a comprehensive but individualized treatment approach, and regardless of the mode of therapy, careful follow-up is essential. Images PMID:7747500

Pelvic floor dysfunction--does menopause duration matter?

2013-10-01

To explore the effect of menopause and hormone replacement therapy on pelvic organ prolapse and pelvic floor muscle function. The records of patients who attended a tertiary urogynaecological center were reviewed retrospectively. A standardised interview included menopausal age, i.e. years since last period or onset of menopausal symptoms, current or previous hormone use. The clinical examination included prolapse assessment (POP-Q) and palpation of the levator ani muscle. 4D transperineal ultrasound, supine and after voiding, was performed in all patients. Volume data sets were analysed for pelvic organ descent and measures of contractility and distensibility of the pelvic floor at a later date, blinded to all clinical data. Of 311 women seen during the inclusion period, 65% were postmenopausal. Current systemic or local hormone use was reported by 7% and 6%, respectively. 163 women (52%) reported prolapse symptoms with a mean bother of 5.7/10. Significant pelvic organ prolapse was found on clinical examination (POP-Q stage≥2) in 77%, and diagnosed on ultrasound in 61%. On multivariate analysis, controlling for calendaric age, parity and levator avulsion, there was no evidence for menopausal age as an independent predictor of any symptom and sign of pelvic organ prolapse and pelvic floor muscle function. Local oestrogen use and past or present hormone replacement therapy had no detectable effect on any pelvic floor parameter. Hormone deficiency following menopause is unlikely to play a major role in pelvic organ support and levator ani function. Hence, both do not appear to be substantially influenced by local or systemic hormone replacement therapy. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Use of compounded hormone therapy in the United States: report of The North American Menopause Society Survey.

Gass, Margery L S; Stuenkel, Cynthia A; Utian, Wulf H; LaCroix, Andrea; Liu, James H; Shifren, Jan L

2015-12-01

A national survey was conducted to determine the extent of use of compounded hormone therapy (C-HT) and to characterize the differences between C-HT users and users of hormone therapy approved by the US Food and Drug Administration (FDA-HT users). This Internet survey enrolled 3,725 women aged 40 to 84 years who were postmenopausal or experiencing the menopause transition. The sample was weighted slightly by age, region, education, and race to reflect population attributes based on US Census data. Overall, 9% of women were current users of HT, and 28% of all respondents were ever-users of HT. C-HT users represented 31% of ever-users of HT, 35% of current users of HT, and 41% of ever-users aged 40 to 49 years. Approximately 13% of ever-users indicated current or past use of testosterone. The most cited reason for using HT was vasomotor symptoms (∼70%). Nonapproved indications for using HT were selected more often by C-HT users. There were four reports of endometrial cancer among the 326 C-HT users compared with none reported among the 738 FDA-HT users. Significance was not determined because of small numbers. This survey indicates substantial use of C-HT across the country and the possibility of higher rates of endometrial side effects with such products. There is a need for standardized data collection on the extent of use of compounded hormones and their potential risks.

Menopausal hormone therapy for primary prevention: why the USPSTF is wrong.

The US Preventive Services Task Force (USPSTF) Draft Recommendation statement on Menopausal Hormone Therapy: Primary Prevention for Chronic Diseases, released in May 2017, perpetuates a major disconnect between the primary population affected, women within roughly 10 years of menopause, and the data cited. Furthermore, major elements of the evidence relied upon have been misinterpreted or misstated, particularly in regard to coronary heart disease and breast cancer, for which there is no statistically significant evidence of harm. As currently drafted, the recommendations reiterate the USPSTF statements of 2012, 2005 and 2002, and will perpetuate egregious harm to the public health. In an attempt to avoid that outcome and to facilitate a return to rational discourse regarding menopausal hormone therapy, an ad hoc group of experts in menopausal health submitted this comprehensive response to the USPSTF.

Menopausal Symptom Relief and Side Effects Experienced by Women Using Bioidentical Hormone Replacement Therapy and Synthetic Conjugated Equine Estrogen and/or Progestin Hormone Replacement Therapy, Part 1.

PubMed

Deleruyelle, Laura J

2016-01-01

The use of compounded bioidentical hormone replacement therapy by menopausal women has become a popular alternative to traditional synthetic conjugated equine estrogen and progestin hormone replacement therapy due to safety concerns raised by recent studies. However, due to the lack of randomized, large-scale trials to evaluate the efficacy and side-effect profile of compounded bioidentical hormone replacement therapy many healthcare providers are reluctant to prescribe such therapy. The purpose of this study was to compare women's menopausal symptom relief and side effects experienced when using compounded bioidentical hormone replacement therapy and traditional hormone replacement therapy. A descriptive comparative design was used. Inferential and descriptive statistical procedures including a paired difference t -test, two-sample t -test, and f tests (percentage, mean, standard deviation, frequency) were run on the Statistical Package for the Social Sciences. The framework used to guide this study was Lenz and Pugh's Theory of Unpleasant Symptoms. Surveys were distributed once to a convenient sample of women aged 35 and older when they dropped off or picked up their prescriptions at a pharmacy. Of the 216 surveys distributed, 70 were returned from those women taking compounded bioidentical hormone replacement therapy and 53 from traditional hormone replacement therapy. The survey contained 15 questions pertaining to age, duration of hormone replacement therapy, type and formulation of hormone replacement therapy, reasons for initiating hormone replacement therapy, symptoms before and one month after hormone replacement therapy, and side effects related to hormone replacement therapy. The results of this study will be summarized in forthcoming articles in this series. Copyright© by International Journal of Pharmaceutical Compounding, Inc.

Current and future medical treatments for patients with acromegaly.

2016-08-01

Acromegaly is a relatively rare condition of growth hormone (GH) excess associated with significant morbidity and, when left untreated, high mortality. Therapy for acromegaly is targeted at decreasing GH and insulin-like growth hormone 1 levels, ameliorating patients' symptoms and decreasing any local compressive effects of the pituitary adenoma. The therapeutic options for acromegaly include surgery, medical therapies (such as dopamine agonists, somatostatin receptor ligands and the GH receptor antagonist pegvisomant) and radiotherapy. However, despite all these treatments option, approximately 50% of patients are not adequately controlled. In this paper, the authors discuss: 1) efficacy and safety of current medical therapy 2) the efficacy and safety of the new multireceptor-targeted somatostatin ligand pasireotide 3) medical treatments currently under clinical investigation (oral octreotide, ITF2984, ATL1103), and 4) preliminary data on the use of new injectable and transdermal/transmucosal formulations of octreotide. This expert opinion supports the need for new therapeutic agents and modalities for patients with acromegaly.

Potential role for mammalian target of rapamycin inhibitors as first-line therapy in hormone receptor–positive advanced breast cancer

PubMed Central

Beck, J Thaddeus

2015-01-01

Despite advances in cytotoxic chemotherapy and targeted therapies, 5-year survival rates remain low for patients with advanced breast cancer at diagnosis. This highlights the limited effectiveness of current treatment options. An improved understanding of cellular functions associated with the development and progression of breast cancer has resulted in the creation of a number of novel targeted molecular therapies. However, more work is needed to improve outcomes, particularly in the first-line recurrent or metastatic hormone receptor–positive breast cancer setting. The phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (mTOR) pathway is a major intracellular signaling pathway that is often upregulated in breast cancer, and overactivation of this pathway has been associated with primary or developed resistance to endocrine treatment. Clinical data from the Phase III Breast Cancer Trials of Oral Everolimus-2 (BOLERO-2) study of the mTOR inhibitor everolimus combined with exemestane in hormone receptor–positive advanced breast cancer were very promising, highlighting the potential role of mTOR inhibitors in combination with endocrine therapies as a first-line treatment option for these patients. It is hoped that the use of mTOR inhibitors combined with current standard-of-care endocrine therapies, such as aromatase inhibitors, in the first-line advanced breast cancer setting may result in greater antitumor effects and also delay or reverse treatment resistance.

Objective To examine the associations of reproductive factors and exogenous hormone use with risk of Parkinson’s disease (PD) among postmenopausal women. Methods The study comprised 119,166 postmenopausal women ages 50–71 years in the NIH-AARP Diet and Health Study, who completed a baseline questionnaire in 1995–1996 and a follow-up survey in 2004–2006. A total of 410 self-reported PD diagnoses were identified between 1995 and 2006. Multivariate odds ratios (OR) and 95% confidence intervals (CI) were derived from logistic regression models. Results PD risk was not significantly associated with female reproductive factors including age at menarche, age at first live birth, parity, and age at menopause. For example, compared with women with natural menopause at ages 50–54 years, the ORs were 1.18, (95% CI 0.78–1.79) for women with natural menopause at ages <45, 1.19 (0.88–1.61) for ages 45–49, and 1.33 (0.91–1.93) for ages 55 or later. We found that oral contraceptive use for ≥10 years (vs. never use) was associated with lower PD risk (OR=0.59; 0.38–0.92) but shorter use showed no association. Use of menopausal hormone therapy showed inconsistent results. Compared with non-hormone users at baseline, current hormone users of <5 years showed a higher risk of PD (OR=1.52; 1.11–2.08). However, no associations were observed for past hormone users or current users of ≥5 years. Conclusions Overall, this large prospective study provides little support for an association between female reproductive factors and PD risk. Our findings on long-term oral contraceptive use and current hormone therapy warrant further investigations. PMID:24352877

Purpose: Gender-affirming surgeries and hormone therapy are medically necessary treatments to alleviate gender dysphoria; however, significant gaps exist in the research and clinical literature on surgery utilization and age of hormone therapy initiation among transgender adults. Methods: We conducted a retrospective review of electronic health record data from a random sample of 201 transgender patients of ages 18-64 years who presented for primary care between July 1, 2010 and June 30, 2015 (inclusive) at an urban community health center in Boston, MA. Fifty percent in our analyses were trans masculine (TM), 50% trans feminine, and 24% reported a genderqueer/nonbinary gender identity. Regression models were fit to assess demographic, gender identity-related, sexual history, and mental health correlates of gender-affirming surgery and of age of hormone therapy initiation. Results: Overall, 95% of patients were prescribed hormones by their primary care provider, and the mean age of initiation of masculinizing or feminizing hormone prescriptions was 31.8 years (SD=11.1). Younger age of initiation of hormone prescriptions was associated with being TM, being a student, identifying as straight/heterosexual, having casual sexual partners, and not having past alcohol use disorder. Approximately one-third (32%) had a documented history of gender-affirming surgery. Factors associated with increased odds of surgery were older age, higher income levels, not identifying as bisexual, and not having a current psychotherapist. Conclusion: This study extends our understanding of prevalence and factors associated with gender-affirming treatments among transgender adults seeking primary care. Findings can inform future interventions to expand delivery of clinical care for transgender patients.

2017-05-01

We conducted a systematic review and meta-analysis of studies that evaluated the effect of hormonal therapy [estrogen therapy including oral contraceptive pills (OCP)] and bisphosphonates in preventing bone loss in patients with functional hypothalamic amenorrhea (FHA). We searched several electronic databases for controlled and noncontrolled studies that enrolled females of any age presenting with FHA (including athletic, weight loss, and stress-associated amenorrhea/oligomenorrhea) through 9 January 2017. The outcomes of interest were fractures and bone mineral density (BMD). Random effects meta-analysis was used to pool outcomes across studies expressed as weighted mean difference and 95% confidence interval (CI). Nine studies reporting on 280 patients that received different hormonal therapies were included. We did not identify studies that evaluated bisphosphonates. Meta-analysis demonstrated a statistically significant increase in BMD of the lumbar spine in patients receiving hormonal therapy after a median follow-up of 12 months (weighted mean difference, 0.032 g/cm 2 ; 95% CI, 0.017 to 0.047; percentage change in BMD, 3.30%; 95% CI, 1.74 to 4.86). There was no substantial effect of receiving hormonal therapy on BMD of the femoral neck, trochanteric region, Ward triangle, or total body BMD. The quality of evidence was low because of the high risk of bias, imprecision (small sample size), and indirectness (as BMD is a surrogate outcome). None of the studies reported the incidence of fractures. The current evidence does not support using hormonal therapy for the sole purpose of improving bone health in patients with FHA. There are no data about bisphosphonates in this population.

Summary Differential cerebral metabolic effects of various hormone therapy formulations, and their associations with cognitive status, remain to be established. The principal aim of the current study wasto assess relationships between regional cerebral metabolism and estrogen-based hormone therapies. Postmenopausal women (n=53) at elevated risk for Alzheimer’s disease (AD) were on estrogen-containing hormone therapy for at least one year prior to enrollment in a prospective, randomized clinical trial. Subjects underwent an FDG-PET scan, along with neuropsychological, medical, and demographic assessments at time of enrollment, to be repeated one year following randomization to hormone therapy continuation versus discontinuation, and results from analyses of the baseline assessments are reported here. Across all subjects, years of endogenous estrogen exposure correlated most closely with metabolism in right superior frontal gyrus (p<0.0005). Women taking 17β-estradiol (E) performed 3 standard deviations higher in verbal memory than women taking conjugated equine estrogen (CEE), and their verbal memory performance positively correlated with metabolism in Wernicke’s (p=0.003) and auditory association (p=0.002) areas. Women taking progesterone-plus-estrogen had lower metabolism than women taking unopposed estrogen within the mesial and inferior lateral temporal regions (p<0.0005) and the inferior frontal cortex, contralateral to Broca’s area (p<0.0005). In conclusion, particular areas of relatively preserved metabolism were seen in women with more years of endogenous estrogen exposure, as well as in women taking estradiol-based formulations or estrogen therapies unopposed by progesterone, together suggesting regionally specific neuroprotective estrogenic effects.

Women taking 17β-estradiol (E) performed three standard deviations higher in verbal memory than women taking conjugated equine estrogen (CEE), and their verbal memory performance positively correlated with metabolism in Wernicke's (p=0.003) and auditory association (p=0.002) areas. Women taking progesterone-plus-estrogen had lower metabolism than women taking unopposed estrogen within the mesial and inferior lateral temporal regions (p<0.0005) and the inferior frontal cortex, contralateral to Broca's area (p<0.0005). In conclusion, particular areas of relatively preserved metabolism were seen in women with more years of endogenous estrogen exposure, as well as in women taking estradiol-based formulations or estrogen therapies unopposed by progesterone, together suggesting regionally specific neuroprotective estrogenic effects.

Objective To analyze the treatment effect of calcium + Vitamin D supplementation, hormone therapy, both, and neither on cardiovascular disease risk factors. Methods We conducted a prospective, randomized, double-blind, placebo controlled trial among Women's Health Initiative participants. The predefined primary outcome was low-density lipoprotein cholesterol (LDL-C). Results Between September 1993 to October 1998, a total of 68,132 women aged 50-79 were recruited and randomized to the WHI-Dietary Modification (WHI-DM) (n=48,835) and WHI-Hormone Therapy (WHI-HT) trials (n=27,347). Subsequently, 36,282 women from WHI-HT (16,089) and WHI-DM (n=25,210) trials were randomized in the WHI-calcium + Vitamin D (WHI-CaD) trial to 1,000 mg of elemental calcium carbonate plus 400 IU of vitamin D3 daily or placebo. Our study group included 1,521 women who participated in both the HT and CaD trials and were in the 6% subsample of trial participants with blood sample collections at baseline and years 1, 3, and 6. The average treatment effect with 95% confidence interval, for LDL-C, compared to placebo, was −1.6 ,(95th CI–5.5, 2.2) mg/dL for calcium + Vitamin D-alone, −9.0 (95th CI, −13.0, −5.1) mg/dL for hormone therapy alone, and −13.8 (95th CI,−17.8, −9.8) mg/dL for the combination. There was no evidence of a synergistic effect of calcium + Vitamin D + hormone therapy on LDL-C (p-value for interaction (p-int) = 0.26) except in those with low total intakes of vitamin D, for whom there was a significant synergistic effect on LDL (p-int = 0.03). Conclusion Reductions in LDL-C were greater among women randomized to both calcium + Vitamin D and hormone therapy than for those randomized to either intervention alone or to placebo. The treatment effect observed in the calcium + Vitamin D + hormone therapy combination group may be additive rather than synergistic. For clinicians and patients deciding to begin calcium + Vitamin D supplementation, current use of hormone therapy should not influence that decision. PMID:27926633

Gut hormones: the future of obesity treatment?

McGavigan, Anne K; Murphy, Kevin G

2012-01-01

Obesity is a major worldwide health problem. The treatment options are severely limited. The development of novel anti-obesity drugs is fraught with efficacy and safety issues. Consequently, several investigational anti-obesity drugs have failed to gain marketing approval in recent years. Anorectic gut hormones offer a potentially safe and viable option for the treatment of obesity. The prospective utility of gut hormones has improved drastically in recent years with the development of longer acting analogues. Additionally, specific combinations of gut hormones have been demonstrated to have additive anorectic effects. This article reviews the current stage of anti-obesity drugs in development, focusing on gut hormone-based therapies. PMID:22452339

Abstract Purpose: Gender-affirming surgeries and hormone therapy are medically necessary treatments to alleviate gender dysphoria; however, significant gaps exist in the research and clinical literature on surgery utilization and age of hormone therapy initiation among transgender adults. Methods: We conducted a retrospective review of electronic health record data from a random sample of 201 transgender patients of ages 18–64 years who presented for primary care between July 1, 2010 and June 30, 2015 (inclusive) at an urban community health center in Boston, MA. Fifty percent in our analyses were trans masculine (TM), 50% trans feminine, and 24% reported a genderqueer/nonbinary gender identity. Regression models were fit to assess demographic, gender identity-related, sexual history, and mental health correlates of gender-affirming surgery and of age of hormone therapy initiation. Results: Overall, 95% of patients were prescribed hormones by their primary care provider, and the mean age of initiation of masculinizing or feminizing hormone prescriptions was 31.8 years (SD=11.1). Younger age of initiation of hormone prescriptions was associated with being TM, being a student, identifying as straight/heterosexual, having casual sexual partners, and not having past alcohol use disorder. Approximately one-third (32%) had a documented history of gender-affirming surgery. Factors associated with increased odds of surgery were older age, higher income levels, not identifying as bisexual, and not having a current psychotherapist. Conclusion: This study extends our understanding of prevalence and factors associated with gender-affirming treatments among transgender adults seeking primary care. Findings can inform future interventions to expand delivery of clinical care for transgender patients. PMID:29159310

Hormone therapy in acne.

Underlying hormone imbalances may render acne unresponsive to conventional therapy. Relevant investigations followed by initiation of hormonal therapy in combination with regular anti-acne therapy may be necessary if signs of hyperandrogenism are present. In addition to other factors, androgen-stimulated sebum production plays an important role in the pathophysiology of acne in women. Sebum production is also regulated by other hormones, including estrogens, growth hormone, insulin, insulin-like growth factor-1, glucocorticoids, adrenocorticotropic hormone, and melanocortins. Hormonal therapy may also be beneficial in female acne patients with normal serum androgen levels. An understanding of the sebaceous gland and the hormonal influences in the pathogenesis of acne would be essential for optimizing hormonal therapy. Sebocytes form the sebaceous gland. Human sebocytes express a multitude of receptors, including receptors for peptide hormones, neurotransmitters and the receptors for steroid and thyroid hormones. Various hormones and mediators acting through the sebocyte receptors play a role in the orchestration of pathogenetic lesions of acne. Thus, the goal of hormonal treatment is a reduction in sebum production. This review shall focus on hormonal influences in the elicitation of acne via the sebocyte receptors, pathways of cutaneous androgen metabolism, various clinical scenarios and syndromes associated with acne, and the available therapeutic armamentarium of hormones and drugs having hormone-like actions in the treatment of acne.

Effect of rejuvenation hormones on spermatogenesis.

To review the current literature for the effect of hormones used in rejuvenation clinics on the maintenance of spermatogenesis. Review of published literature. Not applicable. Men who have undergone exogenous testosterone (T) and/or anabolic androgenic steroid (AAS) therapies. None. Semen analysis, pregnancy outcomes, and time to recovery of spermatogenesis. Exogenous testosterone and anabolic androgenic steroids suppress intratesticular testosterone production, which may lead to azoospermia or severe oligozoospermia. Therapies that protect spermatogenesis involve human chorionic gonadotropin (hCG) therapy and selective estrogen receptor modulators (SERMs). The studies examining the effect of human growth hormone (HGH) on infertile men are uncontrolled and unconvincing, but they do not appear to negatively impact spermatogenesis. At present, routine use of aromatase inhibitors is not recommended based on a lack of long-term data. The use of hormones for rejuvenation is increasing with the aging of the Baby Boomer population. Men desiring children at a later age may be unaware of the side-effect profile of hormones used at rejuvenation centers. Testosterone and anabolic androgenic steroids have well-established detrimental effects on spermatogenesis, but recovery may be possible with cessation. Clomiphene citrate, human growth hormone (HGH)/insulin-like growth factor-1 (IGF-1), human chorionic gonadotropin (hCG), and aromatase inhibitors do not appear to have significant negative effects on sperm production, but quality data are lacking.

2017-01-01

Objective: We conducted a systematic review and meta-analysis of studies that evaluated the effect of hormonal therapy [estrogen therapy including oral contraceptive pills (OCP)] and bisphosphonates in preventing bone loss in patients with functional hypothalamic amenorrhea (FHA). Methods: We searched several electronic databases for controlled and noncontrolled studies that enrolled females of any age presenting with FHA (including athletic, weight loss, and stress-associated amenorrhea/oligomenorrhea) through 9 January 2017. The outcomes of interest were fractures and bone mineral density (BMD). Random effects meta-analysis was used to pool outcomes across studies expressed as weighted mean difference and 95% confidence interval (CI). Results: Nine studies reporting on 280 patients that received different hormonal therapies were included. We did not identify studies that evaluated bisphosphonates. Meta-analysis demonstrated a statistically significant increase in BMD of the lumbar spine in patients receiving hormonal therapy after a median follow-up of 12 months (weighted mean difference, 0.032 g/cm2; 95% CI, 0.017 to 0.047; percentage change in BMD, 3.30%; 95% CI, 1.74 to 4.86). There was no substantial effect of receiving hormonal therapy on BMD of the femoral neck, trochanteric region, Ward triangle, or total body BMD. The quality of evidence was low because of the high risk of bias, imprecision (small sample size), and indirectness (as BMD is a surrogate outcome). None of the studies reported the incidence of fractures. Conclusion: The current evidence does not support using hormonal therapy for the sole purpose of improving bone health in patients with FHA. There are no data about bisphosphonates in this population. PMID:29264505

Disease activity is a major factor in menstrual disorders in systemic lupus erythematosus (SLE) patients not receiving alkylating therapy. However, the ovarian reserve of SLE women with normal menstruation is still unclear. Twenty-three SLE patients naïve to cytotoxic agents (SLE group) and nineteen SLE patients receiving current or previous cyclophosphamide (CTX) therapy (without other cytotoxic agents; SLE-CTX group) were enrolled. Twenty-one age-matched healthy women served as controls. All patients and controls had a regular menstrual cycle. Basal hormone levels, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and anti-Müllerian hormone (AMH), and antral follicle count (AFC) were analyzed in the two study groups and compared with the control group. No significant differences were found between the SLE, SLE-CTX, and control groups in age, body mass index (BMI), and basal FSH and LH levels. The E2 (P=0.023) levels were high and the AMH (P=0.000) values and AFC (P=0.001) were significantly lower in the SLE and SLE-CTX groups compared to control. However, these values were similar between the SLE and SLE-CTX groups. SLE patients not receiving alkylating therapy who had normal menstruation and short illness duration still had an impaired ovarian reserve.

Old issues and new perspectives on prostate cancer hormonal therapy: the molecular substratum.

PubMed

Reis, Leonardo Oliveira

2012-09-01

Secondary hormonal therapy is a treatment option in patients with castration-resistant prostate cancer (CRPC); however, it is underutilized and is room for optimization and improvement. In this context, androgen receptor (AR) is the Achilles' heel, being critically important and various mechanisms ranging from receptor mutations to secondary signaling pathways are responsible for some of the biological heterogeneity, demanding a multimodal approach. A comprehensive review of the peer-reviewed literature is performed on the topic of molecular mechanisms supporting secondary hormonal therapies, including expanded alternative hormonal therapies for CRPC. Essential concepts in clinical treatment of patients with progression on primary hormonal therapy are maintaining the castrate state, accounting for the intermittency phenomenon and sequentially using oral antiandrogens and adrenolytics heading to androgen depletion microenvironment. Survival prolongation, pain relief or measurable improvement in tumor-related symptoms should be persecuted and are considered to be a tangible benefit of obvious worth to the patient. Understanding the underlying molecular substratum is of paramount importance to hormonal therapy optimization in this context once current androgen-depletion strategies are incomplete, and residual androgens as well as alternative routes contribute to sustained AR activity and disease progression to a lethal phenotype. One or many mechanisms may be playing a role, even within the same patient and lastly are potential targets for treatment. Five fundamental mechanisms mediated through the AR to promote tumor growth (three of which depend on ligand signaling) added to the stem cell pathway must be recognized in CRPC. They are persistence of intratumoral androgens as a result of in situ steroidogenesis or adrenal source; AR mutations that allow promiscuous activation by otherwise nonsignaling ligands; wild-type AR gene amplification; alterations in AR coactivator-to-corepressor ratio that impact transcription; outlaw AR pathways that bypass the need for androgens by signaling through crosstalk with other ligand-bound receptors, cytokines, or transactivation of activated tyrosine kinase receptors in the cytosol.

Yang, Hu

2016-02-01

Dendrimers possess discrete highly compact nanostructures constituted of successive branched layers. Soon after the inception of dendrimers, recognition of their tunable structures and biologically favorable properties provoked a great enthusiasm in delving deeply into the utility of dendrimers for biomedical and pharmaceutical applications. One of the most important nanotechnology applications is the development of nanomedicines for targeted cancer therapies. Tremendous success in targeted therapies has been achieved with the use of dendrimer-based nanomedicines. This article provides a concise review on latest advances in the utility of dendrimers in immunotherapies and hormone therapies. Much basic and clinical research has been done since the invention of dendrimers, which are highly branched nano-sized molecules with the ability to act as carriers in nanomedicine. In this concise review article, the authors highlighted the current use of dendrimers in immunotherapies and hormone therapies in the fight against cancers. Copyright © 2015 Elsevier Inc.

Many physicians remain uncertain about prescribing hormone therapy for symptomatic women at the onset of menopause. The American Society for Reproductive Medicine (ASRM) convened a multidisciplinary group of healthcare providers to discuss the efficacy and risks of hormone therapy for symptomatic women, and to determine whether it would be appropriate to treat women at the onset of menopause who were complaining of menopausal symptoms. Numerous controlled clinical trials consistently demonstrate that hormone therapy, administered via oral, transdermal, or vaginal routes, is the most effective treatment for vasomotor symptoms. Topical vaginal formulations of hormone therapy should be preferred when prescribing solely for the treatment of symptoms of vulvar and vaginal atrophy. Data from the Women's Health Initiative indicate that the overall attributable risk of invasive breast cancer in women receiving estrogen plus progestin was 8 more cases per 10,000 women-years. No increased risk for invasive breast cancer was detected for women who never used hormone therapy in the past or for those receiving estrogen only. Hormone therapy is not effective for the treatment of cardiovascular disease and that the risk of cardiovascular disease with hormone therapy is principally in older women who are considerably postmenopause. Healthy symptomatic women should be offered the option of hormone therapy for menopausal symptoms. Symptom relief with hormone therapy for many younger women (at the onset of menopause) with menopausal symptoms outweighs the risks and may provide an overall improvement in quality of life. Hormone therapy should be individualized for symptomatic women. This involves tailoring the regimen and dose to individual needs.

Sex Hormone Effects on Physical Activity Levels: Why Doesn’t Jane Run as Much as Dick?

Bowen, Robert S.; Turner, Michael J.; Lightfoot, J. Timothy

2010-01-01

The relationship between physical activity levels and disease rates have become an important health related concern in the developed world. Heart disease, certain cancers, and obesity persist at epidemic rates in the United States and Western Europe. Increased physical activity levels have been shown to reduce the occurrence of many chronic diseases leading to reductions in the burden on the health care system. Activity levels in humans are affected by many cultural and environmental factors, nevertheless current research points to a strong biological input with potential genetic, neurological, and endocrinological origins. Of unique interest, the sex hormones appear to have a very strong influence on activity levels. The current animal literature suggests that females tend to be more active than males due to biological pathways of estrogenic origin. The majority of human epidemiological and anthropological data, on the contrary, suggest women are less active than men in spite of this inherent activity-increasing mechanism. The purpose of this manuscript was to review the current literature regarding the control of physical activity levels by the sex hormones in humans. Using the natural transitional phases of the aging endocrine system, natural periodicity of the menstrual cycle, and pharmacological/hormone replacement therapy as variable experimental stages, some authors have been able to provide some information regarding the existence of an inherent activity-increasing mechanism in humans. In brief, activity levels during life stages prior to and after menopause do not significantly differ, despite the vast changes in sex hormone levels and function. Activity difference throughout a regular menstrual cycle do not appear to influence activity levels in humans either—an effect that is pronounced in the female rodent. The use of hormone replacement therapies provide researchers with more systematic controls over hormone modulation in human subjects; however, this benefit comes with additional confounding variables, mostly due to disease or other states of malfunction. Despite the addition of these confounding factors, minor changes to the activity pattern have been observed in women, especially during the initial administration for the therapy. Observations are yet to be made in male subjects during replacement therapy. In general, some evidence exists suggesting that a biological mechanism—extending from the sex hormones—influences activity in humans. Unfortunately, despite a small number of investigative reports, the paucity of human research investigating how the sex hormones affect activity levels in humans prevents conclusive delineation of the mechanisms involved. Future research in this unique sub-field of endocrinology and exercise science utilizing more appropriate research protocols and effective techniques will provide definitive evidence of such mechanisms.

To evaluate the quality of information presented and claims made on websites offering bioidentical hormone therapy (BHT) products or services. A quantitative content analysis was completed on 100 websites promoting or offering BHT products or services. Websites were identified through Google search engine from September to October 2013. Search terms included "bioidentical hormone therapy" or "bioidentical progesterone," accompanied by "purchase or buy," "service," or "doctors." The Brief DISCERN instrument was used to determine the quality of the health information. Websites were from Canada (59%), United States (38%), and other countries (3%). Almost half of the websites originated from medical clinics (47%), and healthcare professionals offering BHT services included physicians (50%), pharmacists (19%), and naturopaths (16%). Majority of websites promoted BHT as custom-compounded formulations (62%), with only 27% indicating that BHT is also commercially available. Websites overall claimed that BHT had less risk compared with conventional hormone therapy (62%). BHT was described as having less breast cancer risk (40%), whereas over a quarter of websites described BHT as "protective" for breast cancer. Websites mainly targeted women (99%), with males mentioned in 62% of websites. Product descriptors used to promote BHT included individualization (77%), natural (70%), hormone imbalance (56%), and antiaging (50%). The mean Brief DISCERN score was 15, indicating lower quality of information. Claims made about BHT on the internet are misleading and not consistent with current professional organizations' recommendations. Understanding how BHT may be promoted on the internet can help healthcare professionals when educating patients.

Abstract and Background Abstract Many physicians remain uncertain about prescribing hormone therapy for symptomatic women at the onset of menopause. The American Society for Reproductive Medicine (ASRM) convened a multidisciplinary group of healthcare providers to discuss the efficacy and risks of hormone therapy for symptomatic women, and to determine whether it would be appropriate to treat women at the onset of menopause who were complaining of menopausal symptoms. Major Findings Numerous controlled clinical trials consistently demonstrate that hormone therapy, administered via oral, transdermal, or vaginal routes, is the most effective treatment for vasomotor symptoms.

Conclusions Healthy symptomatic women should be offered the option of hormone therapy for menopausal symptoms. Symptom relief with hormone therapy for many younger women (at the onset of menopause) with menopausal symptoms outweighs the risks and may provide an overall improvement in quality of life. Hormone therapy should be individualized for symptomatic women. This involves tailoring the regimen and dose to individual needs. Background The use of hormone therapy in menopausal patients underwent a dramatic shift following the published results of the Heart and Estrogen/Progestin Replacement Study (HERS) and the Women's Health Initiative (WHI). Hersh and colleagues[1] evaluated national trends in hormone therapy use between January 1995 and July 2003 using the National Prescription Audit and the National Disease and Therapeutic Index databases. Prior to the release of the HERS and WHI results, approximately 42% of women aged 50–74 years were taking hormone therapy. Following the publication of HERS and WHI results in 2002, hormone therapy exposure declined to 28% of women in this age group. Further, annual prescriptions fell 38%, from 91.0 million in 2001 to 56.9 million in 2003. The greatest decline in hormone use was among the oral estrogen and oral estrogen/progestin preparations, contrasting that of transdermal and vaginal formulations which remained stable. HERS showed that in women with preexisting coronary heart disease (CHD), hormone therapy (conjugated equine estrogens [CEE] 0.625 mg and medroxyprogesterone acetate [MPA] 2.5 mg) was not effective as a means of preventing cardiovascular events and was associated with an increased risk for myocardial infarction in the first year in some women.[2] Similarly, the attributable risk (per 10,000 person-years) as reported by the WHI was 7 more CHD events, 8 more strokes, and 8 more invasive breast cancers, as well as 5 fewer hip fractures and 6 fewer colorectal cancers.[3] However, selective reporting from the popular media and some scientific sources have clouded the overall results from WHI by emphasizing results in terms of relative risks. For example, the 29% increase in CHD, 41% increase in stroke, 26% increase in breast cancer, 37% reduction in colorectal cancer, and 34% reduction in hip fractures were presented as a meaningful increase in risk rather than risks which were all less than 1.5 times the placebo rate. In the case of CHD, the final data analysis found that the relative risk decreased from 29% to 24%, and the overall risk of CHD did not achieve statistical significance.[4] A number of position papers by major organizations have attempted to clarify the risks and benefits with hormone therapy in the aftermath of the recent clinical trials. However, despite such efforts, the popular media failed to correctly communicate the clinical implications of the results for everyday practice of providing healthcare to the individual patient. The influence of the media on this matter was underscored by a postal survey of 1700 current users of hormone therapy in Sweden. Hoffmann and colleagues[5] found that women (53–54 years of age) perceived hormone therapy as more risky and less beneficial in 2003 (post HERS II and WHI) compared with 1999. The major sources of information that women relied on were from print media (43.8%) and television/radio (31.7%). Only 18.3% of women received information about hormone therapy from their healthcare providers. Use of hormone therapy decreased from 40.5% to 25.3%, and this decline was significantly correlated with the changes in attitudes towards hormone therapy (P < .001). Many physicians also remain uncertain about prescribing hormone therapy for symptomatic women at the onset of menopause. For example, Williams and colleagues[6] conducted a postal survey in March 2004 of all primary care physicians in Florida about their understanding of the risks and benefits of hormone therapy. The respondents comprised 600 primary care specialists, including 203 ob/gyns, 145 internists, 219 family practitioners, and 33 “other.” They found that respondents overestimated the magnitude of risks and benefits with hormone therapy 67% of the time. The study authors postulated that the lack of understanding regarding attributable risk and relative risk may have contributed to the overestimation of risk (and benefit). These concepts will be discussed later in this article. The data from Williams and colleagues, as well as others, underscore the need to educate physicians to address perceptions of hormone therapy based on WHI findings and clarify the appropriate use of hormone therapy in symptomatic menopausal women. In October 2004, the American Society for Reproductive Medicine (ASRM) reported the results of an online survey of 556 reproductive health professionals at its annual meeting. Nearly 100% of the reproductive health professionals surveyed agreed that their patients are confused about menopausal treatments, and 73% said that they spend a considerable amount of time counseling their menopausal patients about the best treatment. On the basis of the survey results and many informal conversations, ASRM concluded that additional guidance and educational tools were needed to assist general gynecologists and primary care practitioners in appropriate decision-making for the treatment of symptomatic menopausal women. In November 2005, ASRM supported a workshop that convened a multidisciplinary group of healthcare providers to discuss whether it would be appropriate to treat healthy women at the onset of menopause who were complaining of menopausal symptoms. This was not a consensus meeting and there was no intent to duplicate or modify position papers of major organizations such as the American College of Obstetrics and Gynecologists, American Society for Reproductive Medicine, the North American Menopause Society, etc. Eighteen national societies whose members provide primary care for women were invited to send representatives to the workshop. It was predetermined, however, that these member representatives were representing themselves and not the official positions of the societies. Presentations focused on hormone therapy as a therapeutic option for the major symptoms (ie, vasomotor symptoms, vulvovaginal problems, mood/depression, and changes in sleep and sexual function) associated with the onset of menopause. This publication is not a position statement, nor does it represent the official positions of the societies who sent representatives. Rather, this document is a condensed summary of the presentations, discussions, and clinical experience of the group in addressing this important clinical scenario of the symptomatic menopausal woman seeking treatment.

Male factor contributes to 50%–60% of overall infertility but is solely responsible in only 20% of couples. Although most male factor infertility is ascertained from an abnormal semen analysis, other male factors can be contributory especially if the sample returns normal. Male infertility can be due to identifiable hormonal or anatomical etiologies that may be reversible or irreversible. This manuscript will highlight existing guidelines and our recommendations for hormone evaluation for male infertility and empiric therapies including multivitamins, estrogen receptor modulators (clomiphene), estrogen conversion blockers (anastrozole), and hormone replacement.

Aim. Intravenous leiomyomatosis (IVL) with cardiac extension (CE) is a rare variant of benign uterine leiomyoma. Incomplete resection has a recurrence rate of over 30%. Different hormonal treatments have been described following incomplete resection; however no standard therapy currently exists. We review the literature for medical treatments options following incomplete resection of IVL with CE. Methods. Electronic databases were searched for all studies reporting IVL with CE. These studies were then searched for reports of patients with inoperable or incomplete resection and any further medical treatments. Our database was searched for patients with medical therapy following incomplete resection of IVL with CE and their results were included. Results. All studies were either case reports or case series. Five literature reviews confirm that surgery is the only treatment to achieve cure. The uses of progesterone, estrogen modulation, gonadotropin-releasing hormone antagonism, and aromatase inhibition have been described following incomplete resection. Currently no studies have reviewed the outcomes of these treatments. Conclusions. Complete surgical resection is the only means of cure for IVL with CE, while multiple hormonal therapies have been used with varying results following incomplete resection. Aromatase inhibitors are the only reported treatment to prevent tumor progression or recurrence in patients with incompletely resected IVL with CE.

The uses of progesterone, estrogen modulation, gonadotropin-releasing hormone antagonism, and aromatase inhibition have been described following incomplete resection. Currently no studies have reviewed the outcomes of these treatments. Conclusions. Complete surgical resection is the only means of cure for IVL with CE, while multiple hormonal therapies have been used with varying results following incomplete resection. Aromatase inhibitors are the only reported treatment to prevent tumor progression or recurrence in patients with incompletely resected IVL with CE. PMID:26783463

The treatment of acne, especially severe acne, remains a challenge to dermatologists. Therapies include retinoids, antibiotics, hormones, lights, lasers, and various combinations of these modalities. Acne is currently considered a chronic rather than an adolescent condition. The appropriate treatment depends on the patient and the severity of disease. The purpose of this study was to review current therapies for acne of all severities and to introduce the 650-μs 1064-nm laser for the treatment of acne. © 2017 Wiley Periodicals, Inc.

Somatotropin in the treatment of growth hormone deficiency and Turner syndrome in pediatric patients: a review

PubMed Central

Reh, Christina Southern; Geffner, Mitchell E

2010-01-01

Growth hormone (GH), also known as somatotropin, is a peptide hormone that is synthesized and secreted by the somatotrophs of the anterior pituitary gland. The main action of GH is to stimulate linear growth in children; however, it also fosters a healthy body composition by increasing muscle and reducing fat mass, maintains normal blood glucose levels, and promotes a favorable lipid profile. This article provides an overview of the normal pathophysiology of GH production and action. We discuss the history of GH therapy and the development of the current formulation of recombinant human GH given as daily subcutaneous injections. This paper reviews two of the longest standing FDA-approved indications for GH treatment, GH deficiency and Turner syndrome. We will highlight the pathogenesis of these disorders, including presentations, presumed mechanism(s) for the associated short stature, and diagnostic criteria, with a review of stimulation test benefits and pitfalls. This review also includes current recommendations for GH therapy to help maximize final height in these children, as well as data demonstrating the efficacy and safety of GH treatment in these populations.

The pedicled transverse rectus abdominis myocutaneous (TRAM) flap is a reliable reconstructive option in breast cancer patients; however, it carries known risk of donor site hernia formation. Some hormonal therapy drugs have been associated with hernia formation in animal models. Minimal data exist concerning impact of hormonal therapy for breast cancer on abdominal donor site complications after breast reconstruction. Patients who underwent TRAM flap for breast cancer or high-risk status at a single institution by the senior author from 2003 to 2015 were identified. Charts were reviewed. Patient demographics, comorbidities, treatments, and abdominal complications were recorded. Patients were divided into groups based on use of hormonal therapy as well as exposure to specific drugs. Statistical analyses were performed. A total of 358 patients were included. Overall hernia rate was 5.9%. About 231 (64.5%) patients had hormonal therapy, whereas 127 (35.5%) did not. Difference in hernia formation was not statistically significant between the hormonal therapy group (6.9%) and the no hormonal therapy group (3.9%; P = 0.359). Patients exposed to tamoxifen and those exposed to anastrozole had no significant difference in complication rates compared with the no hormonal therapy group, whereas patients exposed to letrozole had increased rate of hernia (13.5%; P = 0.037) and infection (21.6%; P = 0.013) compared with the no hormonal therapy group (3.9% and 7.1%, respectively). Hormonal therapy is a useful adjunct for chemoprevention in breast cancer; however, use of letrozole in patients undergoing reconstruction with pedicled TRAM can lead to increase in certain complication rates.

Graves' disease is autoimmune hyperthyroidism caused by pathological stimulation of thyroid-stimulation hormone-receptor antibodies. The decision on changing the therapy can be made on time by determining the prognostic factors of thyrosuppressive drug therapy outcome. The aim of the study was to determine the significance of thyroid-stimulation hormone-receptor antibodies level on the prediction of therapy outcome. The study was prospective and involved 106 drug-treated patients with newly diagnosed Graves' disease. Thyroid-stimulation hormone-receptor antibodies level was measured at the beginning of therapy, during therapy and 12 months after it had been introduced. No statistically significant difference in the level of thyroid-stimulation hormone-receptor antibodies was found at the beginning of disease and 12 months after the introduction of thyrosuppressive drug therapy among the patients who had been in remission and those who had not. Regardless of the outcome, thyroid-stimulation hormone-receptor antibodies level significantly decreased in all patients 12 months after the therapy had been introduced. The level of thyroid-stimulation hormone-receptor antibodies at the beginning of disease and 12 months after the introduction of therapy cannot predict the outcome of thyrosuppressive drug therapy.

Background Even after the Women's Health Initiative (WHI) found that the risks of menopausal hormone therapy (hormone therapy) outweighed benefit for asymptomatic women, about half of gynecologists in the United States continued to believe that hormones benefited women's health. The pharmaceutical industry has supported publication of articles in medical journals for marketing purposes. It is unknown whether author relationships with industry affect promotional tone in articles on hormone therapy. The goal of this study was to determine whether promotional tone could be identified in narrative review articles regarding menopausal hormone therapy and whether articles identified as promotional were more likely to have been authored by those with conflicts of interest with manufacturers of menopausal hormone therapy. Methods and Findings We analyzed tone in opinion pieces on hormone therapy published in the four years after the estrogen-progestin arm of the WHI was stopped. First, we identified the ten authors with four or more MEDLINE-indexed reviews, editorials, comments, or letters on hormone replacement therapy or menopausal hormone therapy published between July 2002 and June 2006. Next, we conducted an additional search using the names of these authors to identify other relevant articles. Finally, after author names and affiliations were removed, 50 articles were evaluated by three readers for scientific accuracy and for tone. Scientific accuracy was assessed based on whether or not the findings of the WHI were accurately reported using two criteria: (1) Acknowledgment or lack of denial of the risk of breast cancer diagnosis associated with hormone therapy, and (2) acknowledgment that hormone therapy did not benefit cardiovascular disease endpoints. Determination of promotional tone was based on the assessment by each reader of whether the article appeared to promote hormone therapy. Analysis of inter-rater consistency found moderate agreement for scientific accuracy (κ = 0.57) and substantial agreement for promotional tone (κ = 0.65). After discussion, readers found 86% of the articles to be scientifically accurate and 64% to be promotional in tone. Themes that were common in articles considered promotional included attacks on the methodology of the WHI, arguments that clinical trial results should not guide treatment for individuals, and arguments that observational studies are as good as or better than randomized clinical trials for guiding clinical decisions. The promotional articles we identified also implied that the risks associated with hormone therapy have been exaggerated and that the benefits of hormone therapy have been or will be proven. Of the ten authors studied, eight were found to have declared payment for speaking or consulting on behalf of menopausal hormone manufacturers or for research support (seven of these eight were speakers or consultants). Thirty of 32 articles (90%) evaluated as promoting hormone therapy were authored by those with potential financial conflicts of interest, compared to 11 of 18 articles (61%) by those without such conflicts (p = 0.0025). Articles promoting the use of menopausal hormone therapy were 2.41 times (95% confidence interval 1.49–4.93) as likely to have been authored by authors with conflicts of interest as by authors without conflicts of interest. In articles from three authors with conflicts of interest some of the same text was repeated word-for-word in different articles. Conclusion There may be a connection between receiving industry funding for speaking, consulting, or research and the publication of promotional opinion pieces on menopausal hormone therapy.

Targeting the relaxin hormonal pathway in prostate cancer.

Neschadim, Anton; Summerlee, Alastair J S; Silvertown, Joshua D

2015-11-15

Targeting the androgen signalling pathway has long been the hallmark of anti-hormonal therapy for prostate cancer. However, development of androgen-independent prostate cancer is an inevitable outcome to therapies targeting this pathway, in part, owing to the shift from cancer dependence on androgen signalling for growth in favor of augmentation of other cellular pathways that provide proliferation-, survival- and angiogenesis-promoting signals. This review focuses on the role of the hormone relaxin in the development and progression of prostate cancer, prior to and after the onset of androgen independence, as well as its role in cancers of other reproductive tissues. As the body of literature expands, examining relaxin expression in cancerous tissues and its role in a growing number of in vitro and in vivo cancer models, our understanding of the important involvement of this hormone in cancer biology is becoming clearer. Specifically, the pleiotropic functions of relaxin affecting cell growth, angiogenesis, blood flow, cell migration and extracellular matrix remodeling are examined in the context of cancer progression. The interactions and intercepts of the intracellular signalling pathways of relaxin with the androgen pathway are explored in the context of progression of castration-resistant and androgen-independent prostate cancers. We provide an overview of current anti-hormonal therapeutic treatment options for prostate cancer and delve into therapeutic approaches and development of agents aimed at specifically antagonizing relaxin signalling to curb tumor growth. We also discuss the rationale and challenges utilizing such agents as novel anti-hormonals in the clinic, and their potential to supplement current therapeutic modalities. © 2014 UICC.

This study aims to assess whether the timing of menopausal hormone therapy initiation in relation to onset of menopause and hormone therapy duration is associated with myocardial infarction risk. This study was based on the Stockholm Heart Epidemiology Program, a population-based case-control study including 347 postmenopausal women who had experienced a nonfatal myocardial infarction and 499 female control individuals matched for age and residential area. Odds ratios (with 95% CIs) for myocardial infarction were calculated using logistic regression. Early initiation of hormone therapy (within 10 y of onset of menopause or before age 60 y), compared with never use, was associated with an odds ratio of 0.87 (95% CI, 0.58-1.30) after adjustments for lifestyle factors, body mass index, and socioeconomic status. For late initiation of hormone therapy, the corresponding odds ratio was 0.97 (95% CI, 0.53-1.76). For hormone therapy duration of 5 years or more, compared with never use, the adjusted odds ratio was 0.64 (95% CI, 0.35-1.18). For hormone therapy duration of less than 5 years, the odds ratio was 0.97 (95% CI, 0.63-1.48). Neither the timing of hormone therapy initiation nor the duration of therapy is significantly associated with myocardial infarction risk.

The current treatment of pituitary adenomas requires a balance of conservative management, surgical resection, and in select tumor types, molecular therapy. Acromegaly treatment is an evolving field where our understanding of molecular targets and drug therapies has improved treatment options for patients with excess growth hormone levels. We highlight the use of molecular therapies in this disease process and advances in this field, which may represent a paradigm shift for the future of pituitary adenoma treatment.

Management of sexual dysfunction in postmenopausal breast cancer patients taking adjuvant aromatase inhibitor therapy

2007-01-01

Treatment with aromatase inhibitors for postmenopausal women with breast cancer has been shown to reduce or obviate invasive procedures such as hysteroscopy or curettage associated with tamoxifen-induced endometrial abnormalities. The side effect of upfront aromatase inhibitors, diminished estrogen synthesis, is similar to that seen with the natural events of aging. The consequences often include vasomotor symptoms (hot flushes) and vaginal dryness and atrophy, which in turn may result in cystitis and vaginitis. Not surprisingly, painful intercourse (dyspareunia) and loss of sexual interest (decreased libido) frequently occur as well. Various interventions, both non-hormonal and hormonal, are currently available to manage these problems. The purpose of the present review is to provide the practitioner with a wide array of management options to assist in treating the sexual consequences of aromatase inhibitors. The suggestions in this review are based on recent literature and on the recommendations set forth both by the North American Menopause Association and in the clinical practice guidelines of the Society of Gynaecologists and Obstetricians of Canada. The complexity of female sexual dysfunction necessitates a biopsychosocial approach to assessment and management alike, with interventions ranging from education and lifestyle changes to sexual counselling, pelvic floor therapies, sexual aids, medications, and dietary supplements—all of which have been reported to have a variable, but often successful, effect on symptom amelioration. Although the use of specific hormone replacement—most commonly local estrogen, and less commonly, systemic estrogen with or without an androgen, progesterone, or the additional of an androgen in an estrogenized woman (or a combination)—may be highly effective, the concern remains that in patients with estrogen-dependent breast cancer, including those receiving anti-estrogenic adjuvant therapies, the use of these hormones may be attended with potential risk. Therefore, non-hormonal alternatives should in all cases be initially tried with the expectation that symptomatic relief can often be achieved. First-line therapy for urogenital symptoms, notably vaginal dryness and dyspareunia, should be the non-hormonal group of preparations such as moisturizers and precoital vaginal lubricants. In patients with estrogen-dependent breast cancer (notably those receiving anti-estrogenic adjuvant therapies) and severely symptomatic vaginal atrophy that fails to respond to non-hormonal options, menopausal hormone replacement or prescription vaginal estrogen therapy may considered. Systemic estrogen may be associated with risk and thus is best avoided. Judicious use of hormones may be appropriate in the well-informed patient who gives informed consent, but given the potential risk, these agents should be prescribed only after mutual agreement of the patient and her oncologist.

Genetic polymorphisms in phase I and phase II enzymes and breast cancer risk associated with menopausal hormone therapy in postmenopausal women.

PubMed

2010-01-01

Recent findings indicate a greater risk of postmenopausal breast cancer with estrogen-progestagen therapy than estrogen monotherapy, and more so for current than past use. Few studies have examined individual genetic susceptibility to the effects of menopausal hormone therapy. We used two population-based case-control studies with 3,155 postmenopausal breast cancer patients and 5,496 controls to evaluate modification of breast cancer risk associated with duration of hormone use by genes involved in hormone metabolism and detoxification. Twenty-eight polymorphisms in eight genes of phase I (CYP1A1, CYP1A2, CYP1B1, CYP2C9, CYP2C19, CYP3A4, CYP3A5, CYP3A7) and nine genes of phase II enzymes (COMT, GSTM1, GSTM3, GSTP1, GSTT1, SULT1A1, UGT1A1, UGT1A6, UGT2B7) were genotyped. The risk associated with duration of use of combined estrogen-progestagen therapy was significantly modified by genetic polymorphisms located in CYP1B1, GSTP1, and GSTT1. In homozygote carriers of the CYP1B1_142_G and the CYP1B1_355 _T variant alleles, adjusted odds ratios (OR) per year of use were 1.06 (95% confidence interval (CI) = 1.02-1.09) and 1.06 (95% CI = 1.03-1.09), respectively, compared with 1.02 (95% CI = 1.01-1.03) in non-carriers of either polymorphism (p(interaction) = 0.01). Carriers of the functional GSTT1 allele and the GSTP1_341_T allele were at significantly higher risks associated with hormone use compared with non-carriers (p(interaction) = 0.0001 and 0.02). CYP1A1_2452_C>A significantly reduced the risk associated with duration of use of estrogen monotherapy (p(interaction) = 0.01). The finding regarding GSTT1 was still statistically significant after corrections for multiple comparisons. Postmenopausal breast cancer risk associated with hormone therapy may be modified by genetically determined variations in phase I and II enzymes involved in steroid hormone metabolism.

This article, Part 1 of the Endocrine Society of Australia's position statement on male hypogonadism, focuses on assessment of male hypogonadism, including the indications for testosterone therapy. (Part 2 will deal with treatment and therapeutic considerations.) Key points and recommendations are:Pathological hypogonadism arises due to diseases of the hypothalamus or pituitary gland (hypogonadotropic hypogonadism) or testes (hypergonadotropic hypogonadism). It is a clinical diagnosis with a pathological basis, confirmed by hormone assays.Hormonal assessment is based on measurement of circulating testosterone, luteinising hormone (LH) and follicle-stimulating hormone (FSH) concentrations. Measurement of sex hormone-binding globulin levels can be informative, but use of calculated free testosterone is not recommended for clinical decision making.Testosterone replacement therapy is warranted in men with pathological hypogonadism, regardless of age.Currently, there are limited data from high-quality randomised controlled trials with clinically meaningful outcomes to justify testosterone treatment in older men, usually with chronic disease, who have low circulating testosterone levels but without hypothalamic, pituitary or testicular disease.Obesity, metabolic syndrome and type 2 diabetes are associated with lowering of circulating testosterone level, but without elevation of LH and FSH levels. Whether these are non-specific consequences of non-reproductive disorders or a correctable deficiency state is unknown, but clear evidence for efficacy and safety of testosterone therapy in this setting is lacking.Glucocorticoid and opioid use is associated with possibly reversible reductions in circulating testosterone level, without elevation of LH and FSH levels. Where continuation of glucocorticoid or opioid therapy is necessary, review by an endocrinologist may be warranted.Changes in management as result of the position statement: Men with pathological hypogonadism should be identified and considered for testosterone therapy, while further research is needed to clarify whether there is a role for testosterone in these other settings.

The history of hormone therapy use and recent controversy related to heart disease and breast cancer arising from prevention trial outcomes.

PubMed

Alexander, Ivy M

2012-01-01

The reasons for hormone therapy use have changed dramatically over time from being very popular for the purpose of preserving youth in women to menopause-related symptom management, disease prevention, and now back to menopause-related symptom management. Over time, several important risks associated with the use of hormone therapy have become evident, causing dramatic reductions in the use of hormone therapy for periods of time following identification of these risks. Most recently, randomized controlled prevention trials that evaluated hormone therapy for the purpose of reducing or preventing coronary heart disease among women have found that hormone therapy is associated with increased rather than decreased risks for coronary heart disease. The most recent of these trials again identified increased risks for breast cancer associated with estrogen plus progestogen therapy. The evolving evidence base from these randomized controlled prevention trials is complicated and in some cases contradictory. Specifically, the data suggest that the timing of when hormone therapy is initiated once a woman is postmenopausal may influence her risk for developing heart disease and breast cancer. In this article, contradictory evidence is carefully sifted so risks and benefits can be weighed by clinicians when partnering with women to individualize decisions about using hormone therapy. © 2012 by the American College of Nurse-Midwives.

Thyroid storm: an updated review.

Chiha, Maguy; Samarasinghe, Shanika; Kabaker, Adam S

2015-03-01

Thyroid storm, an endocrine emergency first described in 1926, remains a diagnostic and therapeutic challenge. No laboratory abnormalities are specific to thyroid storm, and the available scoring system is based on the clinical criteria. The exact mechanisms underlying the development of thyroid storm from uncomplicated hyperthyroidism are not well understood. A heightened response to thyroid hormone is often incriminated along with increased or abrupt availability of free hormones. Patients exhibit exaggerated signs and symptoms of hyperthyroidism and varying degrees of organ decompensation. Treatment should be initiated promptly targeting all steps of thyroid hormone formation, release, and action. Patients who fail medical therapy should be treated with therapeutic plasma exchange or thyroidectomy. The mortality of thyroid storm is currently reported at 10%. Patients who have survived thyroid storm should receive definite therapy for their underlying hyperthyroidism to avoid any recurrence of this potentially fatal condition. © The Author(s) 2013.

Controversial endocrine interventions for the aged.

Specific endocrine changes occur with the ageing process. The last decade has witnessed significant progress in the basic and clinical science of ageing, thereby rejuvenating the interest in anti-ageing medicine, especially that of hormone replacement, by medical professionals and the lay public. However, endocrine manipulation as a therapeutic strategy for ageing is still evolving as continuing research attempts to answer the many questions of what it can achieve at the risk of incurring unknown long-term adverse effects. The current day doctor is confronted with a host of options, and will benefit from a synopsis of the latest evidence before making the most appropriate decision for aged patients seeking hormonal replacement therapy as a means to counter the effects of ageing. This review aims to give a rapid overview of the endocrine profile of geriatric population and the studies on the more controversial hormonal replacement therapies for the aged.

Dynamic changes in the hypothalamic-pituitary-adrenal axis during growth hormone therapy in children with growth hormone deficiency: a multicenter retrospective study.

Wang, Limin; Wang, Qian; Li, Guimei; Liu, Wendong

2015-09-01

The objective of this study was to investigate changes in the hypothalamic-pituitary-adrenal (HPA) axis after recombinant human growth hormone (rhGH) therapy. Subjects included children with growth hormone deficiency (GHD). We conducted a multicenter, retrospective study that assessed 72 GHD patients treated with rhGH during 6 months. Patients were classified into two groups: isolated GHD (IGHD; n=20) and multiple pituitary hormone deficiencies (MPHD; n=52). The HPA axis and other hormones were evaluated at baseline and every 3 months. In the MPHD group, 32 patients had adrenocorticotrophic hormone deficiency and received hydrocortisone before rhGH therapy. In the other 20/52 MPHD patients, the cortisol (COR) level was significantly reduced after rhGH therapy. Moreover, 10 patients showed low COR levels. In the IGHD group, COR levels also decreased, but remained within the normal range. During rhGH therapy, COR levels were reduced, particularly in patients with MPHD. HPA axis should be monitored during rhGH therapy.

Are there differences in the effectiveness of pelvic floor muscle training on pelvic floor muscle strength and urinary incontinence symptoms in postmenopausal women who are and are not using hormone therapy? Randomised, controlled trial with concealed allocation, blinded assessors, and intention-to-treat analysis. Ninety-nine postmenopausal women, 38 of whom were using daily systemic oestrogen/progestogen therapy. The experimental group (n=51) received an intensive supervised pelvic floor muscle training protocol, and the control group (n=48) received no intervention. The randomisation was stratified by hormone therapy use. Change in pelvic floor muscle strength assessed with manometry at 12 weeks. Prevalence and severity of urinary incontinence symptoms were assessed using questionnaires. Eighty-eight women provided data that could be included in the analysis. Pelvic floor muscle training increased pelvic floor muscle strength by 8.0 cmH 2 O (95% CI 3.4 to 12.6) in women not using hormone therapy and by -0.9 cmH 2 0 (95% CI -6.5 to 4.8) in women using hormone therapy (interaction p=0.018). A sensitivity analysis showed that the greater training effect in women who were not using hormone therapy was still apparent if the analysis was conducted on percentage change in strength rather than absolute change in strength. There was also a significantly greater effect of training in women not using hormone therapy on prevalence of urinary incontinence symptoms (ratio of odds ratios=7.4; interaction p=0.028). The difference in effects on severity of urinary incontinence symptoms was not statistically significant (interaction p=0.37).

The news media play a critical role in communicating health information to the public. The unexpected findings in July 2002 about increased health risks associated with hormone therapy provided an opportunity to examine the process of translating scientific findings to reporters through communication intermediaries and appraise subsequent reporting in newspapers in the United States. Using qualitative research software, a qualitative analysis was conducted in 2006 to consider four types of messages: (1) hormone therapy health risks outweighed benefits (balance); (2) adverse hormone therapy health outcomes (health risk); (3) positive hormone therapy health outcomes (benefit); and (4) risk level (magnitude). The print materials analyzed included the original 2002 Journal of American Medical Association (JAMA) article and editorial; JAMA and National Institutes of Health (NIH) press releases; the NIH press conference transcript; and 198 articles about hormone therapy in 22 U.S. newspapers published from July to September 2002. The major study finding that hormone therapy risks outweighed benefits was reported consistently and accurately. Analyses of language and numbers on risk magnitude, and its interpretation revealed some variability, both within the translation materials and news stories. When risk numbers were included in newspaper stories, absolute risk was used more often than relative risk. Despite much criticism of journalists' coverage of health issues, U.S. newspaper reporting about hormone therapy in 2002 was generally consistent. Several translational and communication strategies used with hormone therapy may be applicable to other efforts that involve working with reporters on major health stories or events. An important process oversight was the absence of hormone therapy communication efforts and guidance directed specifically to medical practitioners.

The timing of the menopause transition has remained fairly constant throughout history. It represents a milestone in female health and, after passing through it, women experience increased musculoskeletal and cardiovascular morbidity. Muscle performance is an important determinant of functional capacity and quality of life among the elderly and is also involved in the maintenance of balance. Therefore, good muscle strength can prevent fragility fractures and lessen the burden of osteoporosis. Muscle strength begins to decline during the perimenopausal years and this phenomenon seems to be partly estrogen dependent. Randomized controlled trials have indicated that hormone replacement therapy may prevent a decline in muscle performance, although the exact mechanism of estrogen-dependent sarcopenia remains to be clarified. Exercises have been shown to improve postmenopausal muscle performance and hormone replacement therapy may also potentiate these beneficial effects. Improvement or maintenance of muscle strength alone, however, may not be considered as a primary indication for long-term hormone replacement therapy in view of current knowledge of its risks and benefits. Work history and educational background may be associated with postmenopausal muscle performance, which itself has unique associations with skeletal and cardiovascular diseases.

Premature menopause is a major concern of younger women undergoing adjuvant therapy for breast cancer. Hormone replacement therapy is contraindicated in women with a history of breast cancer. Non-hormonal medications show a range of bothersome side-effects. There is growing evidence that cognitive behavioral therapy (CBT) and physical exercise can have a positive impact on symptoms in naturally occurring menopause. The objective of this study is to investigate the efficacy of these interventions among women with breast cancer experiencing treatment-induced menopause. In a randomized, controlled, multicenter trial, we are evaluating the effectiveness of CBT/relaxation, of physical exercise and of these two program elements combined, in reducing menopausal symptoms, improving sexual functioning, reducing emotional distress, and in improving the health-related quality of life of younger breast cancer patients who experience treatment-induced menopause. 325 breast cancer patients (aged < 50) are being recruited from hospitals in the Amsterdam region, and randomly allocated to one of the three treatment groups or a 'waiting list' control group. Self-administered questionnaires are completed by the patients at baseline, and at 12 weeks (T1) and 6 months (T2) post-study entry. Upon completion of the study, women assigned to the control group will be given the choice of undergoing either the CBT or physical exercise program. Cognitive behavioral therapy and physical exercise are potentially useful treatments among women with breast cancer undergoing treatment-induced, premature menopause. For these patients, hormonal and non-hormonal therapies are contraindicated or have a range of bothersome side-effects. Hence, research into these interventions is needed, before dissemination and implementation in the current health care system can take place.

In the physiological view the human cardiomyocytes express receptors of gonadotropin-releasing hormone and follicle-stimulating hormone. The local effects of these hormones in the heart are related also to some interstitial cells, such as endothelial cells with follicle-stimulating hormone receptors and immune cells with gonadotropin-releasing hormone receptors. The administration of androgen deprivation therapy in patients with prostate cancer is associated with increased incidence of cardiovascular complications. It is suggested that negative action of this therapy on cardiovascular system is due to the loss of testosterone but also levels of gonadotropin-releasing hormone and follicle-stimulating hormone are changed by therapy. In this article we review the literature to date with an emphasis on recent investigation focused on potential role of abnormal gonadotropin-releasing hormone and follicle-stimulating hormone levels induced by gonadotropin-releasing hormone agonists on the cardiovascular risk. These facts exacerbate the complexity of specific hormone and cell relationships within heart and vessels. Androgen deprivation therapy reveals the physiological relationships between hormones and specific tissues that are not part of the endocrine system.

Context Hormones regulate neuronal function in brain regions critical to cognition; however the cognitive effects of postmenopausal hormone therapy are controversial. Objective The goal was to evaluate the effect of postmenopausal hormone therapy on neural circuitry involved in spatial working memory. Design A randomized, double-blind placebo-controlled cross-over study was performed. Setting The study was performed in a tertiary care university medical center. Participants Ten healthy postmenopausal women of average age 56.9 years were recruited. Interventions Volunteers were randomized to the order they received hormone therapy, 5 ug ethinyl estradiol and 1 mg norethindrone acetate. Subjects received hormone therapy or placebo for 4 weeks, followed by a one month washout period with no medications, and then received the other treatment for 4 weeks. At the end of each 4 week treatment period a functional magnetic resonance imaging (fMRI) study was performed utilizing a nonverbal (spatial) working memory task, the Visual Delayed Matching to Sample task. Main Outcome Measure The effects of hormone therapy on brain activation patterns were compared to placebo. Results Compared to the placebo condition, hormone therapy was associated with a more pronounced activation in the prefrontal cortex (BA 44 and 45), bilaterally (p<0.001). Conclusions Hormone therapy was associated with more effective activation of a brain region critical in primary visual working memory tasks. The data suggest a functional plasticity of memory systems in older women that can be altered by hormones. PMID:16912129

Background: A number of recent advances in our understanding of thyroid physiology may shed light on why some patients feel unwell while taking levothyroxine monotherapy. The purpose of this task force was to review the goals of levothyroxine therapy, the optimal prescription of conventional levothyroxine therapy, the sources of dissatisfaction with levothyroxine therapy, the evidence on treatment alternatives, and the relevant knowledge gaps. We wished to determine whether there are sufficient new data generated by well-designed studies to provide reason to pursue such therapies and change the current standard of care. This document is intended to inform clinical decision-making on thyroid hormone replacement therapy; it is not a replacement for individualized clinical judgment. Methods: Task force members identified 24 questions relevant to the treatment of hypothyroidism. The clinical literature relating to each question was then reviewed. Clinical reviews were supplemented, when relevant, with related mechanistic and bench research literature reviews, performed by our team of translational scientists. Ethics reviews were provided, when relevant, by a bioethicist. The responses to questions were formatted, when possible, in the form of a formal clinical recommendation statement. When responses were not suitable for a formal clinical recommendation, a summary response statement without a formal clinical recommendation was developed. For clinical recommendations, the supporting evidence was appraised, and the strength of each clinical recommendation was assessed, using the American College of Physicians system. The final document was organized so that each topic is introduced with a question, followed by a formal clinical recommendation. Stakeholder input was received at a national meeting, with some subsequent refinement of the clinical questions addressed in the document. Consensus was achieved for all recommendations by the task force. Results: We reviewed the following therapeutic categories: (i) levothyroxine therapy, (ii) non–levothyroxine-based thyroid hormone therapies, and (iii) use of thyroid hormone analogs. The second category included thyroid extracts, synthetic combination therapy, triiodothyronine therapy, and compounded thyroid hormones. Conclusions: We concluded that levothyroxine should remain the standard of care for treating hypothyroidism. We found no consistently strong evidence for the superiority of alternative preparations (e.g., levothyroxine–liothyronine combination therapy, or thyroid extract therapy, or others) over monotherapy with levothyroxine, in improving health outcomes. Some examples of future research needs include the development of superior biomarkers of euthyroidism to supplement thyrotropin measurements, mechanistic research on serum triiodothyronine levels (including effects of age and disease status, relationship with tissue concentrations, as well as potential therapeutic targeting), and long-term outcome clinical trials testing combination therapy or thyroid extracts (including subgroup effects). Additional research is also needed to develop thyroid hormone analogs with a favorable benefit to risk profile. PMID:25266247

The successful translation of the scientific principles of targeting the breast tumour oestrogen receptor (ER) with the nonsteroidal anti-oestrogen tamoxifen and using extended durations (at least 5 years) of adjuvant therapy, dramatically increased patient survivorship and significantly enhanced a drop in national mortality rates from breast cancer. The principles are the same for the validation of aromatase inhibitors to treat post-menopausal patients but tamoxifen remains a cheap, life-saving medicine for the pre-menopausal patient. Results from the Oxford Overview Analysis illustrate the scientific principle of "longer is better" for adjuvant therapy in pre-menopausal patients. One year of adjuvant therapy is ineffective at preventing disease recurrence or reducing mortality, whereas five years of adjuvant tamoxifen reduces recurrence by 50% which is maintained for a further ten years after treatment stops. Mortality is reduced but the magnitude continues to increase to 30% over a 15-year period. With this clinical database, it is now possible to implement simple solutions to enhance survivorship. Compliance with long-term anti-hormone adjuvant therapy is critical. In this regard, the use of selective serotonin reuptake inhibitors (SSRIs) to reduce severe menopausal side effects may be inappropriate. It is known that SSRIs block the CYP2D6 enzyme that metabolically activates tamoxifen to its potent anti-oestrogenic metabolite, endoxifen. The selective norepinephrine reuptake inhibitor, venlafaxine, does not block CYP2D6, and may be a better choice. Nevertheless, even with perfect compliance, the relentless drive of the breast cancer cell to acquire resistance to therapy persists. The clinical application of long-term anti-hormonal therapy for the early treatment and prevention of breast cancer, focused laboratory research on the discovery of mechanisms involved in acquired anti-hormone resistance. Decades of laboratory study to reproduce clinical experience described not only the unique mechanism of selective ER modulator (SERM)-stimulated breast cancer growth, but also a new apoptotic biology of oestradiol action in breast cancer, following 5 years of anti-hormonal treatment. Oestradiol-induced apoptotic therapy is currently shown to be successful for the short-term treatment of metastatic ER positive breast cancer following exhaustive treatment with anti-hormones. The "oestrogen purge" concept is now being integrated into trials of long-term adjuvant anti-hormone therapy. The Study of Letrazole Extension (SOLE) trial employs "anti-hormonal drug holidays" so that a woman's own oestrogen may periodically purge and kill the nascent sensitized breast cancer cells that are developing. This is the translation of an idea first proposed at the 1992 St. Gallen Conference. Although tamoxifen is the first successful targeted therapy in cancer, the pioneering medicine is more than that. A study of the pharmacology of tamoxifen opened the door for a pioneering application in cancer chemoprevention and created a new drug group: the SERMs, with group members (raloxifene and lasofoxifene) approved for the treatment and prevention of osteoporosis with a simultaneous reduction of breast cancer risk. Thus, the combined strategies of long-term anti-hormone adjuvant therapy, targeted to the breast tumour ER, coupled with the expanding use of SERMs to prevent osteoporosis and prevent breast cancer as a beneficial side effect, have advanced patient survivorship significantly and promise to reduce breast cancer incidence.

Hormone therapy for inmates: a metonym for transgender rights.

PubMed

Maruri, Silpa

2011-01-01

The issue of hormone therapy for transgender inmates, while seemingly limited in importance, is one that involves issues of greater importance for the transgender community. The greatest issue at the heart of the matter is the legal argument that is traditionally used to gain access to hormone therapy: the Eighth Amendment. The Eighth Amendment prohibits deliberate indifference to the medical needs of inmates. Traditionally, transgender inmates have gained access to hormone therapy by appealing to the DSM-IV's classification of Gender Identity Disorder (GID) as a mental illness, and by establishing that prison officials' failure to provide hormone therapy constitutes deliberate indifference to a serious medical need. However, appeal to GID is a double-edged sword: while it allows access to hormone therapy, it does so by describing transgender individuals as somehow sick or infirm. This description is at odds with the transgender community's conceptualization of itself. This Note seeks to square the legal arguments for provision of hormone therapy to transgender inmates with the philosophical backdrop that shapes the transgender rights movement by using Plyler v. Doe as a model. This Note argues that access to hormone therapy by transgender inmates involves the intersection of a quasi-fundamental right with a quasi-suspect class. By utilizing such an argument, the transgender community is not bound by the negative expressive effect that the law may have in describing it as infirm or deficient.

Almost all patients with hormone-refractory prostate cancer under primary androgen deprivation therapy will develop progression, frequently initially marked by an asymptomatic increase of prostate-specific antigen (PSA). Recent data showed that taxane-based chemotherapy offers significant survival benefit to patients with advanced prostate cancer; however, the toxic side effects frequently exert a significant negative impact on the quality of life. At the androgen-independent stage of the cancer, before becoming hormone refractory, progression might still be delayed by secondary manipulation of either androgen or confounding receptors and their signaling pathways. Secondary hormonal manipulations traditionally included antiandrogen withdrawal, second-line antiandrogens, direct adrenal androgen inhibitors, estrogens, and progestins.We discuss the mode of action and application of somatostatin analogs as an emerging secondary hormonal treatment concept in patients with advanced prostate cancer on the basis of the current literature.

Hormonal and antimicrobial therapies are essential to regulate and maintain healthy reproduction in domestic animals. The appropriate and legal use of these compounds is ultimately the responsibility of the veterinarian and other users, with a primary mission to directly protect and promote the health of animals, and indirectly the health of people. The appropriate use of these products is defined by the Federal Food, Drug, and Cosmetic Act, 21 United States of America § 301 et seq and implementing regulations in the Code of Federal Regulations. In the past, use of a drug in an animal for an unapproved use violated this Act. However, passage of the Animal Medicinal Drug Use Clarification Act 1994 legalized the extra-label use of certain animal and human drugs in veterinary practice for treating diseases. This manuscript reviews currently approved hormonal and antimicrobial drugs for use in theriogenology. Considering the ever increasing knowledge in the area of veterinary reproduction, particularly in the treatment and control of reproduction using antimicrobials and hormones, it would be beneficial to widen the therapeutic options in these categories. The potential for widening the therapeutic options is also discussed in this review, by providing a non-exhaustive but essential list of potential new drugs for use in clinical animal reproduction (theriogenology).

Summary Combined pituitary hormonal deficiency (CPHD) is a rare disease that results from mutations in genes coding for transcription factors that regulate the differentiation of pituitary cells. PROP1 gene mutations are one of the etiological diagnoses of congenital panhypopituitarism, however symptoms vary depending on phenotypic expression. We present a case of psychosis in a 36-year-old female with congenital panhypopituitarism who presented with paranoia, flat affect and ideas of reference without a delirious mental state, which resolved with hormone replacement and antipsychotics. Further evaluation revealed that she had a homozygous mutation of PROP1 gene. In summary, compliance with hormonal therapy for patients with hypopituitarism appears to be effective for the prevention and treatment of acute psychosis symptoms. Learning points: Patients with PROP1 gene mutation may present with psychosis with no impairment in orientation and memory. There is currently inadequate literature on this topic, and further study on the possible mechanisms of psychosis as a result of endocrine disturbance is required. Compliance with hormonal therapy for patients with hypopituitarism appears to be effective for prevention and treatment of acute psychosis symptoms. PMID:28458894

Our knowledge of the complex mechanisms underlying energy homeostasis has expanded enormously in recent years. Food intake and body weight are tightly regulated by the hypothalamus, brainstem and reward circuits, on the basis both of cognitive inputs and of diverse humoral and neuronal signals of nutritional status. Several gut hormones, including cholecystokinin, glucagon-like peptide-1, peptide YY, oxyntomodulin, amylin, pancreatic polypeptide and ghrelin, have been shown to play an important role in regulating short-term food intake. These hormones therefore represent potential targets in the development of novel anti-obesity drugs. This review focuses on the role of gut hormones in short- and long-term regulation of food intake, and on the current state of development of gut hormone-based obesity therapies. PMID:20002077

Variations of serum testosterone levels in prostate cancer patients under LH-releasing hormone therapy: an open question.

PubMed

Reis, Leonardo Oliveira

2012-06-01

The hypothesis 'the lower the better when achieving castration levels of testosterone' is based on the data from second-line hormonal manipulation and its molecular basis, and on better oncological results reported for lower castration levels in prostate cancer (PCa) patients, including those achieved with maximal androgen blockade. In this regard, the equivalence of surgical and different pharmacological castrations has been controversial. The modified amino acid structure that makes LH-releasing hormone (LHRH) analogs more potent than LHRH, and the method of delivering the analogs impacts on bioavailibility and potentially causes differences in androgen levels and in its final oncological efficacy. In addition to this, there is a myriad of circumstances, such as those related to ethnic variations and co-morbidities, which uniquely impact on the pharmacological approach in a highly heterogeneous population of castration-resistant prostate cancer (CRPC) patients. Ineffective testosterone suppression through hormonal escape is currently poorly recognized and may result in increased PCa mortality. Until now, the optimal serum testosterone level in patients under castration, and the impact of its variations in patients under LHRH therapy, remain open questions and have been merged to a broad spectra of patients who are highly heterogeneous. This heterogeneity relates to a number of mechanisms regarding response to treatment, which influences the biology of the relapsing tumor and the sensitivity to subsequent therapies in the individual patient. The rationale to achieve testosterone levels below 20-50 ng/dl warrant further investigation as these levels have recently rescued CRPC patients. In the last few years and months, important advancements in prostate cancer treatment have been achieved. Nevertheless, these advances are measured in a few months of additional survival and under high costs, not available to most of the world population, compared with the benefits of hormonal manipulation that are measured in years, there is a huge potential for accessible and durable effect expansion and optimization of treatment, particularly with the current tendency of a more individual approach.

Objective Observational studies suggest that arterial distensibility decreases during menopause; however, the relation to hormone therapy use is controversial. We prospectively studied distensibility and hormone therapy use during different menopause stages. Methods 161 women between 42–61 years of age without cardiovascular disease had carotid artery measurements by ultrasound to calculate the distensibility index at baseline and 3 years later. Menopause stage was classified at each visit as premenopausal, perimenopausal, and postmenopausal. Over 3 years of prospective observation, women were classified as remaining premenopausal, remaining postmenopausal, or transitioning, defined as change from premenopausal-to-perimenopausal, premenopausal-to-postmenopausal, perimenopausal-to-perimenopausal, or perimenopausal-to-postmenopausal. Results Distensibility declined over time in all menopause stages (p<0.0001). Compared to postmenopausal women, premenopausal and transitioning/no hormone therapy women had over twice the decline in distensibility index (p=0.06 and p=0.016, respectively), whereas transitioning/hormone therapy did not differ in distensibility decline (p=0.28). In a multivariate model, change in systolic blood pressure (p<0.0001) and change in pulse pressure (p=0.004) were independent predictors of distensibility index change and served as effect modulators. In the adjusted model, women in the premenopausal and transitioning/no hormone therapy groups had a significantly faster distensibility index decline (p=0.002 and 0.001, respectively) than postmenopausal women, while the transitioning/hormone therapy group did not (p=0.21) Conclusions These findings confirm that menopause transition is associated with reduced vascular compliance. Hormone therapy is associated with better arterial distensibility only during menopause transition. Additional prospective studies are needed to confirm these findings and to determine if hormone therapy use beyond menopause transition is related to distensibility. PMID:26308234

Observational studies have suggested that arterial distensibility decreases during menopause; however, its relationship with hormone therapy use remains controversial. We prospectively studied distensibility and hormone therapy use at different menopause stages. One hundred sixty-one women (aged between 42 and 61 y) without cardiovascular disease underwent carotid artery measurements by ultrasound to calculate distensibility index at baseline and 3 years later. Menopause stage was classified at each visit as premenopausal, perimenopausal, and postmenopausal. Across 3 years of prospective observation, women were classified as remaining premenopausal, remaining postmenopausal, or transitioning (defined as change from premenopausal to perimenopausal, from premenopausal to postmenopausal, from perimenopausal to perimenopausal, or from perimenopausal to postmenopausal). Distensibility declined across time at all menopause stages (P < 0.0001). Compared with postmenopausal women, premenopausal and transitioning/no hormone therapy women had more than twice the decline in distensibility index (P = 0.06 and P = 0.016, respectively), whereas transitioning/hormone therapy women did not differ in distensibility decline (P = 0.28). In a multivariate model, change in systolic blood pressure (P < 0.0001) and change in pulse pressure (P = 0.004) were independent predictors of distensibility index change and served as effect modulators.

These findings confirm that the menopausal transition is associated with reduced vascular compliance. Hormone therapy is associated with better arterial distensibility only during the menopausal transition. Additional prospective studies are needed to confirm these findings and to determine whether hormone therapy use beyond the menopausal transition is related to distensibility.

A cross-sectional study of hormone treatment and hippocampal volume in postmenopausal women: Evidence for a limited window of opportunity

The influence of hormone treatment on brain and cognition in postmenopausal women has been a controversial topic. Contradictory patterns of results have prompted speculation that a critical period, or a limited window of opportunity, exists for hormone treatment to protect against cognitive and neural decline in older women. Consistent with this hypothesis, studies in both humans and rodents indicate that the latency between the time of menopause and the initiation of hormone treatment is an important factor in determining whether hormone treatment will prevent or exacerbate cognitive impairment. In this cross-sectional study of 102 postmenopausal women, we examined whether hippocampal, amygdala, or caudate nucleus volumes and spatial memory performance were related to the interval between menopause and the initiation of hormone treatment. Consistent with a critical period hypothesis, we found that shorter intervals between menopause and the initiation of hormone treatment, as determined by self-report, were associated with larger hippocampal volumes compared with longer intervals between menopause and treatment initiation. Initiation of hormone treatment at the time of menopause was also associated with larger hippocampal volumes when compared to peers who had never used hormone treatment. Furthermore, these effects were independent from potentially confounding factors such as age, years of education, the duration of hormone treatment, current or past use of hormone therapy, the type of therapy, and the age at menopause. Larger hippocampal volumes in women who initiated hormone treatment at the time of menopause failed to translate to improved spatial memory performance. There was no relationship between the timing of hormone initiation, spatial memory performance, and amygdala or caudate nucleus volume. Our results provide support for the idea that there is a limited window of opportunity at the time of menopause for hormone treatment to influence hippocampal volume, yet the degree to which these effects translate to improved memory performance is uncertain.

Triptorelin embonate: a 6-month formulation for prostate cancer.

Whelan, Peter

2010-12-01

Luteinizing hormone releasing hormone (LH RH) agonists are the major agent for androgen deprivation therapy in advanced and metastatic prostate cancer. They also have a role in endometriosis, uterine fibroids and central precocious puberty. Triptorelin embonate 22.5 mg is a new, sustained-release, 6-month formulation of an LH RH agonist. It possesses longer duration of action than the current standard 3-month preparation and appears to have similar efficacy and side effects. The use of LH RH agonists for androgen deprivation in prostate cancer has increased considerably in the last 20 years. Recent work has shown that some of this usage has constituted overtreatment and it is within these newer paradigms of therapy that the new 6-month preparation is situated. The new 6-month LH RH preparation - triptorelin embonate - will be of help in several key areas of therapy for prostate cancer, notably as an adjunct to radiation therapy and chemotherapy. It possesses a similar effect, but with fewer side effects, than those that are now commonly available.

The aim of the study was to evaluate the frequency of hormonal replacement therapy (HRT) application among Polish women aged 40-65, patients of five selected health care institutions located in south-eastern Poland and to determine the most significant factors that influence women's decision to initiate HRT. The next purpose was to establish how the women learned about the possibility of receiving HRT. Women, who never decided to take sex hormones, were asked about the reasons of such decision. The study comprised a group of 1033 women aged 40-65 years living in south-eastern Poland, the patients of various hospital wards and outpatient clinics. The study was conducted from January 2003 to December 2004 using categorized interview technique. The interview questionnaire was constructed by the authors. The statistical analysis was performed on the basis of the chi2 test of independence; log-linear analysis and Pareto's analysis were also used. Research result analysis proves that 30.5% of the examined women have used HRT currently or in the past. The sociodemographic and healthy variables that showed positive correlation with receiving hormonal treatment by midlife women were: age 51-65 years, the presence of climacteric ailments, the absence of monthly bleedings, possessing of permanent life partner and good self-estimation of one's financial status. It was not revealed that better educated women more frequently decide to take HRT. The main sources of women's knowledge about HRT were the mass media and health service employees. Among the reasons for not taking up hormonal treatment the most significant were: lack or small intensification of menopausal ailments as well as the fear of side effects of hormonal replacement therapy.

An Update on Triptorelin: Current Thinking on Androgen Deprivation Therapy for Prostate Cancer.

Merseburger, Axel S; Hupe, Marie C

2016-07-01

Androgen deprivation therapy (ADT) is the mainstay palliative treatment for men with locally advanced and metastatic prostate cancer, and aims to reduce testosterone to levels obtained by surgical castration. Use of gonadotropin-releasing hormone (GnRH) agonists predominates among the ADT options. The GnRH agonist, triptorelin is a first-line hormonal therapy that has demonstrated efficacy and safety in clinical trials of patients with locally advanced non-metastatic or metastatic disease. Sustained-release 1-, 3- and 6-month formulations of triptorelin, administered intramuscularly or subcutaneously, have been developed to provide improved flexibility and convenience for the patient. Head-to-head studies of GnRH agonists are lacking in the field of prostate cancer. Despite the inevitable progression to castration-resistant prostate cancer (CRPC) in most patients receiving ADT, monitoring of testosterone levels needs to improve in routine practice and physicians should not overlook the benefits of continued ADT in their patients when introducing one of the various new treatment options for CRPC. For improved survival outcomes, there remains a need to tailor ADT treatment regimens, novel hormonal agents and chemotherapy according to the individual patient with advanced prostate cancer.

Healthcare resource utilization in breast cancer varies by disease characteristics and treatment choices. However, lack of clarity in guidelines can result in varied interpretation and heterogeneous treatment management and costs. In Europe, the extent of this variability is unclear. Therefore, evaluation of chemotherapy use and costs versus hormone therapy across Europe is needed. This retrospective chart review (N = 355) examined primarily direct costs for chemotherapy versus hormone therapy in postmenopausal women with hormone-receptor-positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) advanced breast cancer across 5 European countries (France, Germany, The Netherlands, Belgium, and Sweden). Total direct costs across the first 3 treatment lines were approximately €10,000 to €14,000 lower for an additional line of hormone therapy-based treatment versus switching to chemotherapy-based treatment. Direct cost difference between chemotherapy-based and hormone therapy-based regimens was approximately €1900 to €2500 per month. Chemotherapy-based regimens were associated with increased resource utilization (managing side effects; concomitant targeted therapy use; and increased frequencies of hospitalizations, provider visits, and monitoring tests). The proportion of patients taking sick leave doubled after switching from hormone therapy to chemotherapy. These results suggest chemotherapy is associated with increased direct costs and potentially with increased indirect costs (lower productivity of working patients) versus hormone therapy in HR+, HER2- advanced breast cancer.

To optimize fertility advice in patients with Hodgkin lymphoma (HL) before therapy and during survivorship, information on the impact of chemotherapy is needed. Therefore, we analyzed gonadal functions in survivors of HL. Women younger than age 40 and men younger than 50 years at diagnosis in ongoing remission at least 1 year after therapy within the German Hodgkin Study Group HD13 to HD15 trials for early- and advanced-stage HL were included. Hormone parameters, menstrual cycle, symptoms of hypogonadism, and offspring were evaluated. A total of 1,323 (55%) of 2,412 contacted female and male survivors were evaluable for the current analysis (mean follow-up, 46 and 48 months, respectively). Follicle-stimulating hormone, anti-Müllerian hormone, and inhibin B levels correlated significantly with therapy intensity (P < .001). Low birth rates were observed in survivors after advanced-stage treatment within the observation time (women, 6.5%; men, 3.3%). Regular menstrual cycle was reported by more than 90% of female survivors of early-stage HL (recovery time mostly ≤ 12 months). After six to eight cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, menstrual activity was strongly related to age (< v ≥ 30 years: 82% v 45%, respectively; P < .001; prolonged recovery time). Thirty-four percent of women age ≥ 30 years suffered severe menopausal symptoms (three- to four-fold more frequently than expected). In contrast, male survivors had mean levels of testosterone within the normal range and reported no increased symptoms of hypogonadism. The present analysis in a large group of survivors of HL provides well-grounded information on gonadal toxicity of currently used treatment regimens and allows risk-adapted fertility preservation and comprehensive support during therapy and follow-up.

Is the growth outcome of children with idiopathic short stature and isolated growth hormone deficiency following treatment with growth hormone and a luteinizing hormone-releasing hormone agonist superior to that obtained by GH alone?

The aim of this study was to evaluate the effect of combined therapy with growth hormone (GH) and luteinizing hormone-releasing hormone agonist (LHRHa) on the near-final height (NFH) of children with idiopathic short stature (ISS) and growth hormone deficiency (GHD) in early puberty. A retrospective analysis of 20 patients with ISS and 9 patients with GHD treated with combined therapy was undertaken. Twelve children with ISS and ten with GHD, treated with GH alone, served as controls. Patients were matched at baseline for chronological age, bone age, height standard deviation score (SDS), and pubertal development. Patients with ISS or GHD treated with combined therapy improved both their predicted adult height (PAH) at 2 years of therapy (ISS, p < 0.001; GHD, p = 0.03) and their NFH (ISS, p < 0.05; GHD, p = 0.05). Treatment with combined therapy did not generate additional benefits on the PAH after 2 years of therapy (ISS children, an increase of 7.9 +/- 4.9 cm with combined therapy vs. 7.3 +/- 6.0 cm with GH; GHD children, an increase of 6.8 +/- 7.8 cm with combined therapy vs. 5 +/- 5.9 cm with GH). The total height gain SDS was higher in patients treated with GH alone compared with those with combined therapy, but the difference was not significant (ISS children, a gain of 2.4 SDS with GH vs. 0.8 SDS with combined therapy; GHD children, a gain of 1.8 SDS with GH vs. 0.6 SDS with combined therapy). Although 2 years of combined treatment with GH and LHRHa improved the PAH and the NFH of ISS and GHD patients in early puberty, this improvement was not significant compared with that observed in similar subjects treated with GH alone.

Late pubertal growth spurt in a girl with growth hormone deficiency: Is Kaufmann therapy effective in a girl with short stature who responds poorly to growth hormone therapy and estrogen-replacement therapy?

A Japanese senior high school girl aged 18 years and 5 months with growth hormone deficiency was referred for primary amenorrhea. Her height was 1.36 m, and her bodyweight was 23.5 kg. She had received daily growth hormone therapy from the age of 5 years. Growth hormone therapy was discontinued at the age of 16 years and 11 months, and estrogen-replacement therapy (ERT) was started to stimulate secondary sexual characteristics. Although ERT was performed until the age of 18 years and 11 months, genital bleeding did not occur. ERT was changed to Kaufmann therapy, and the first genital bleeding occurred 1 year and 4 months later. Finally, regular medically induced menses occurred at the age of 21 years and 10 months. Her height increased by 9 cm in 1 year after the initiation of menstrual bleeding. Kaufmann therapy was associated not only with menstrual bleeding but also with growth spurt. © 2017 Japan Society of Obstetrics and Gynecology.

The emergence of levothyroxine as a treatment for hypothyroidism.

Hennessey, James V

2017-01-01

To describe the historical refinements, understanding of physiology and clinical outcomes observed with thyroid hormone replacement strategies. A Medline search was initiated using the search terms, levothyroxine, thyroid hormone history, levothyroxine mono therapy, thyroid hormone replacement, combination LT4 therapy, levothyroxine Bioequivalence. Pertinent articles of interest were identified by title and where available abstract for further review. Additional references were identified in the course of review of the literature identified. Physicians have intervened in cases of thyroid dysfunction for more than two millennia. Ingestion of animal thyroid derived preparations has been long described but only scientifically documented for the last 130 years. Refinements in hormone preparation, pharmaceutical production and regulation continue to this day. The literature provides documentation of physiologic, pathologic and clinical outcomes which have been reported and continuously updated. Recommendations for effective and safe use of these hormones for reversal of patho-physiology associated with hypothyroidism and the relief of symptoms of hypothyroidism has documented a progressive refinement in our understanding of thyroid hormone use. Studies of thyroid hormone metabolism, action and pharmacokinetics have allowed evermore focused recommendations for use in clinical practice. Levothyroxine mono-therapy has emerged as the therapy of choice of all recent major guidelines. The evolution of thyroid hormone therapies has been significant over an extended period of time. Thyroid hormone replacement is very useful in the treatment of those with hypothyroidism. All of the most recent guidelines of major endocrine societies recommend levothyroxine mono-therapy for first line use in hypothyroidism.

Cardiovascular Disease Among Transgender Adults Receiving Hormone Therapy: A Narrative Review.

Recent reports estimate that 0.6% of adults in the United States, or approximately 1.4 million persons, identify as transgender. Despite gains in rights and media attention, the reality is that transgender persons experience health disparities, and a dearth of research and evidence-based guidelines remains regarding their specific health needs. The lack of research to characterize cardiovascular disease (CVD) and CVD risk factors in transgender populations receiving cross-sex hormone therapy (CSHT) limits appropriate primary and specialty care. As with hormone therapy in cisgender persons (that is, those whose sex assigned at birth aligns with their gender identity), existing research in transgender populations suggests that CVD risk factors are altered by CSHT. Currently, systemic hormone replacement for cisgender adults requires a nuanced discussion based on baseline risk factors and age of administration of exogenous hormones because of concern regarding an increased risk for myocardial infarction and stroke. For transgender adults, CSHT has been associated with the potential for worsening CVD risk factors (such as blood pressure elevation, insulin resistance, and lipid derangements), although these changes have not been associated with increases in morbidity or mortality in transgender men receiving CSHT. For transgender women, CSHT has known thromboembolic risk, and lower-dose transdermal estrogen formulations are preferred over high-dose oral formulations. In addition, many studies of transgender adults focus predominantly on younger persons, limiting the generalizability of CSHT in older transgender adults. The lack of randomized controlled trials comparing various routes and formulations of CSHT, as well as the paucity of prospective cohort studies, limits knowledge of any associations between CSHT and CVD.

Treating type 1 diabetes: from strategies for insulin delivery to dual hormonal control

PubMed Central

McCall, A. L.; Farhy, L. S.

2014-01-01

Type 1 diabetes is a disorder where slow destruction of pancreatic β-cells occurs through autoimmune mechanisms. The result is a progressive and ultimately complete lack of endogenous insulin. Due to β-cell lack, secondary abnormalities in glucagon and likely in incretins occur. These multiple hormonal abnormalities cause metabolic instability and extreme glycemic variability, which is the primary phenotype. As the disease progresses patients often develop hypoglycemia unawareness and defects in their counterregulatory defenses. Intensive insulin therapy may thus lead to 3-fold excess of severe hypoglycemia and severely hinder the effective and safe control of hyperglycemia. The main goal of the therapy for type 1 diabetes has long been physiological mimicry of normal insulin secretion based on monitoring which requires considerable effort and understanding of the underlying physiology. Attainment of this goal is challenged by the nature of the disease and our current lack of means to fully repair the abnormal endocrine pancreas interactive functions. As a result, various insulin preparations has been developed to partially compensate for the inability to deliver timely exogenous insulin directly to the portal/intrapancreatic circulation. It remains an ongoing task to identify the ideal routes and regimens of their delivery and potentially that of other hormones to restore the deficient and disordered hormonal environment of the pancreas to achieve a near normal metabolic state. Several recent technological advances help addressing these goals, including the rapid progress in insulin pumps, continuous glucose sensors, and ultimately the artificial pancreas closed-loop technology and the recent start of dual-hormone therapies.

The aim of the present study was to evaluate the presence of symptoms of current social distress, anxiety and depression in transsexuals. We investigated a group of 187 transsexual patients attending a gender identity unit; 120 had undergone hormonal sex-reassignment (SR) treatment and 67 had not. We used the Social Anxiety and Distress Scale (SADS) for assessing social anxiety and the Hospital Anxiety and Depression Scale (HADS) for evaluating current depression and anxiety. The mean SADS and HADS scores were in the normal range except for the HAD-Anxiety subscale (HAD-A) on the non-treated transsexual group. SADS, HAD-A, and HAD-Depression (HAD-D) mean scores were significantly higher among patients who had not begun cross-sex hormonal treatment compared with patients in hormonal treatment (F=4.362, p=.038; F=14.589, p=.001; F=9.523, p=.002 respectively). Similarly, current symptoms of anxiety and depression were present in a significantly higher percentage of untreated patients than in treated patients (61% vs. 33% and 31% vs. 8% respectively). The results suggest that most transsexual patients attending a gender identity unit reported subclinical levels of social distress, anxiety, and depression. Moreover, patients under cross-sex hormonal treatment displayed a lower prevalence of these symptoms than patients who had not initiated hormonal therapy. Although the findings do not conclusively demonstrate a direct positive effect of hormone treatment in transsexuals, initiating this treatment may be associated with better mental health of these patients.

Risks and safety of combination therapy for hypothyroidism.

Jonklaas, Jacqueline

2016-08-01

Hypothyroidism is currently a condition that can be treated, but not cured. Although levothyroxine reverses stigmata of hypothyroidism in most individuals, some patients feel dissatisfied with 'monotherapy', and this has stimulated interest in 'combination therapy' with both levothyroxine and liothyronine. A search of PubMed was conducted using terms including hypothyroidism, treatment, benefits, risks, and safety. Based on the articles identified, the body of evidence regarding the efficacy of traditional levothyroxine is reviewed. Concerns with levothyroxine therapy including impaired quality of life in treated patients, thyroxine-predominant hormone ratios, and inadvertent iatrogenic thyroid disease are discussed. The trials of combination therapy performed since 1999 were reviewed. The heterogeneity of these trials, both in terms of design and results, is discussed. The potential for new trials to determine whether combination therapy can reverse the dissatisfaction associated with monotherapy, while avoiding non-physiologic hormone ratios, inadvertent thyrotoxicosis, and unacceptable side effects is discussed. Expert commentary: Research regarding which therapy fully reverses hypothyroidism at a tissue and cellular level is ongoing. The field would be advanced by the development of an extended release preparation of liothyronine. In the future regeneration of functional thyroid follicles from stem cells may offer hope for curing hypothyroidism.

Infants with complete growth hormone deficiency may suffer from psychomotor retardation in addition to severe growth failure. Without replacement therapy, they may have a compromised intellectual potential manifesting as learning disabilities and attention-deficit disorders in later life. In this communication, we discuss an infant who showed improvement in physical growth after growth hormone therapy but her psychomotor skills did not improve probably due to late start of treatment. There is a need to start growth hormone therapy as early as possible in infants with complete growth hormone deficiency to avoid adverse effects on psychomotor and brain development.

Hormone therapy in the form of androgen deprivation is a major treatment for advanced prostate cancer. However, if such therapy is overly prolonged, tumour cells may become resistant to this treatment and result in recurrent fatal disease. Long-term hormone deprivation also is associated with side effects poorly tolerated by patients. In contrast, intermittent hormone therapy with alternating on- and off-treatment periods is a possible clinical strategy to delay progression to hormone-refractory disease with the advantage of reduced side effects during the off-treatment periods. In this paper, we first overview previous studies on mathematical modelling of prostate tumour growth under intermittent hormone therapy. The model is categorized into a hybrid dynamical system because switching between on-treatment and off-treatment intervals is treated in addition to continuous dynamics of tumour growth. Next, we present an extended model of stochastic differential equations and examine how well the model is able to capture the characteristics of authentic serum prostate-specific antigen (PSA) data. We also highlight recent advances in time-series analysis and prediction of changes in serum PSA concentrations. Finally, we discuss practical issues to be considered towards establishment of mathematical model-based tailor-made medicine, which defines how to realize personalized hormone therapy for individual patients based on monitored serum PSA levels.

Original Research: Metabolic alterations from early life thyroxine replacement therapy in male Ames dwarf mice are transient.

Ames dwarf mice are exceptionally long-lived due to a Prop1 loss of function mutation resulting in deficiency of growth hormone, thyroid-stimulating hormone and prolactin. Deficiency in thyroid-stimulating hormone and growth hormone leads to greatly reduced levels of circulating thyroid hormones and insulin-like growth factor 1, as well as a reduction in insulin secretion. Early life growth hormone replacement therapy in Ames dwarf mice significantly shortens their longevity, while early life thyroxine (T4) replacement therapy does not. Possible mechanisms by which early life growth hormone replacement therapy shortens longevity include deleterious effects on glucose homeostasis and energy metabolism, which are long lasting. A mechanism explaining why early life T4 replacement therapy does not shorten longevity remains elusive. Here, we look for a possible explanation as to why early life T4 replacement therapy does not impact longevity of Ames dwarf mice. We found that early life T4 replacement therapy increased body weight and advanced the age of sexual maturation. We also find that early life T4 replacement therapy does not impact glucose tolerance or insulin sensitivity, and any deleterious effects on oxygen consumption, respiratory quotient and heat production are transient. Lastly, we find that early life T4 replacement therapy has long-lasting effects on bone mineral density and bone mineral content. We suggest that the transient effects on energy metabolism and lack of effects on glucose homeostasis are the reasons why there is no shortening of longevity after early life T4 replacement therapy in Ames dwarf mice. © 2016 by the Society for Experimental Biology and Medicine.

The side effects of oncological treatment, which appear during or after therapy, are sometimes very annoying for patients and are not adequately treated by physicians. Among the symptoms experienced by breast cancer patients are hot flushes, which result from a natural or cancer therapy-induced menopause. The intensity of hot flushes in breast cancer patients may be more severe than those experienced by women undergoing a natural menopause. Taking into account the incidence of breast cancer and long-lasting hormone-suppression therapies, the problem of hot flushes will affect many women. Hormonal replacement therapy, the most effective therapeutic means for alleviating hot flushes, is usually contraindicated for breast cancer patients. For intense and severe hot flushes, pharmacological treatment using agents from a group of selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors such as venlafaxine or citalopram may be introduced. Other agents from different pharmacological groups, such as clonidine, gabapentin, or pregabalin, have also proved to be effective in treating hot flushes. The efficacy of phytoestrogens has not been proven in randomized clinical trials. The importance of the placebo effect in decreasing vasomotor symptoms has also been reported in many research papers. Educating breast cancer patients in lifestyle changes which decrease the frequency and intensity of vasomotor symptoms can offer significant help too. This paper reviews the current state of research in order to assess the options for the treatment of hot flushes in breast cancer survivors.

Vulvar cancer is a rare malignancy; most tumors are squamous cell type while adenocarcinomas are rare. Primary adenocarcinomas of the vulva predominantly include extramammary Paget's disease and sweat gland carcinomas. Greene first described a rare form of adenocarcinoma in 1936, which was called adenocarcinoma of mammary-like glands of the vulva because of its morphologic and immunohistochemical resemblance to breast adenocarcinomas. In the management of this entity, varying combinations of surgery, radiation therapy, systemic chemotherapy and/or hormonal therapy may be used, as in patients with orthotopic breast carcinoma. However, hormonal therapy leads the way in patients with positive hormonal receptors, where other therapies cannot be used due to comorbidities or advanced age. We present the first reported case of an elderly patient with metastatic vulvar adenocarcinoma arising from mammary-like glands, successfully treated with a combination of surgery and hormonal therapy. © 2012 The Authors.

The sales data of oestrogen replacement products for 8 developing countries from 1993 to 1995 were analyzed. The data from Malaysia, Pakistan, Taiwan, Thailand, Indonesia, Philippines and South Korea showed the increasing use of oestrogen replacement products. The total usage however varied widely, from only US$11,153 (Philippines in 1993) to as much as US$6,306,717 (Taiwan in 1995). In Singapore, where oestrogen replacement is an accepted and established form of therapy for the postmenopausal woman, there has been an increase in the usage of the nonoestrogen replacement products. There are multiple reasons for the increasing sales of hormone replacement products in the developing countries and these are explored in this article. In some of the developing countries, for example China and India, hormone replacement therapy has just been introduced. However, in those developing countries in which hormone replacement therapy is already available, sales figures show increasing usage. The future augurs well for hormone replacement therapy.

Distinctive Tooth-Extraction Socket Healing: Bisphosphonate Versus Parathyroid Hormone Therapy

2014-01-01

Background Patients with osteoporosis who receive tooth extractions are typically on either oral bisphosphonate or parathyroid hormone (PTH) therapy. Currently, the consequence of these therapies on hard- and soft-tissue healing in the oral cavity is not clearly defined. The aim of this study is to determine the differences in the therapeutic effect on tooth-extraction wound healing between bisphosphonate and PTH therapies. Methods Maxillary second molars were extracted in Sprague Dawley rats (n = 30), and either bisphosphonate (zoledronate [Zol]), PTH, or saline (vehicle control [VC]) was administered for 10 days (n = 10 per group). Hard-tissue healing was evaluated by microcomputed tomography and histomorphometric analyses. Collagen, blood vessels, inflammatory cell infiltration, and cathepsin K expression were assessed in soft tissue using immunohistochemistry, quantitative polymerase chain reaction, and immunoblotting. Results Both therapies significantly increased bone fill and suppressed vertical bone loss. However, considerably more devital bone was observed in the sockets of rats on Zol versus VC. Although Zol increased the numbers of blood vessels, the total blood vessel area in soft tissue was significantly smaller than in VC. PTH therapy increased osteoblastic bone formation and suppressed osteoclasts. PTH therapy promoted soft-tissue maturation by suppressing inflammation and stimulating collagen deposition. Conclusion Zoledronate therapy deters whereas PTH therapy promotes hard- and soft-tissue healing in the oral cavity, and both therapies prevent vertical bone loss. PMID:23688101

Lack of physician knowledge about transgender medicine is a barrier to care. An intervention with medical students changed attitudes about providing transgender medical care, but it is unknown whether at the level of postgraduate education an intervention could have a similar effect. We conducted such an intervention with resident-physicians. An intervention on transgender medicine covering the durability of gender identity and hormonal treatment regimens was added to the curriculum for residents. An anonymous survey assessed the residents' knowledge and willingness to assist with hormonal therapy before and after the lecture. The percent of residents who agreed that they felt sufficiently knowledgeable to assist with hormonal therapy for a female-to-male patient increased significantly, from 5% before to 76% following the lecture (χ(2), 24.7; degrees of freedom, 1; P<.001). The percent of residents who reported that they felt sufficiently knowledgeable to assist with hormonal therapy for a male-to-female patient increased significantly, from 5% before to 71% following the lecture (χ(2), 24.0; degrees of freedom, 1; P<.001). The intervention increased resident knowledge about hormonal therapy for hypogonadal men (χ(2), 11.4; degrees of freedom, 1; P<.001) and women (χ(2), 9.4; degrees of freedom, 1; P = .002). The intervention made more residents agree that gender identity has a biologic basis that remains constant (P<.001) and that hormonal and surgical therapies should be offered (P = .047). The lecture significantly increased residents' knowledge and willingness to assist with hormonal therapy for transgender patients.

To provide clinical practice guidelines for the management of painful endometriosis in women without infertility. Systematic review of the literature literature since 2006, level of evidence rating, external proofreading and grading of the recommendation grade by an expert group according to HAS methodology. Combined hormonal contraceptives (COP) and the levonorgestrel-releasing intra-uterin system (LNG-IUS) are recommended as first-line hormonal therapies for the treatment of painful endometriosis (grade B). Second-line therapy relies on oral desogestrel microprogestative, etonogestrel-releasing implant, GnRH analogs (GnRHa) and dienogest (grade C). It is recommended to use add-back therapy containing estrogen in association with GnRHa (grade B). After endometriosis surgery, hormonal treatment relying on COP or LNG-IUS is recommended to prevent pain recurrence (grade B). COP is recommended to reduce the risk of endometrioma recurrence after surgery (grade B) but the prescription of GnRHa is not recommended (grade C). Continuous COP is recommended in case of dysmenorrhea (grade B). GnRHa is not recommended as first line endometriosis treatment for adolescent girl because of the risk of bone demineralization (grade B). The management of endometriosis-induced chronic pain requires an interdisciplinary evaluation. Physical therapies improving the quality of life such as yoga, relaxation or osteopathy can be proposed (expert agreement). Promising medical alternatives are currently under preclinical and clinical evaluation. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Evidence-based practice in women's health: hormone therapy for women at menopause.

2001-01-01

Women's health providers, especially midwives, must take into account the known benefits and risks, as well as the "unknown," when recommending the use of hormone therapy for menopausal women, especially as it relates to heart disease, breast cancer, impaired cognition, and osteoporosis. The most recent evidence available from various studies about the benefits and risks of estrogen and hormone therapy at menopause suggests that, although hormone therapy may be protective in some women against heart disease and osteoporosis, evidence is less certain about the benefits of hormone protection against impaired cognition and the risks of breast cancer with use. The clinical approach used by midwives in which individualizing care based on each woman's health status history as well as preferences is highly appropriate for women in the perimenopausal and menopausal period.

Debate: idiopathic short stature should be treated with growth hormone.

PubMed

Ambler, Geoffrey R; Fairchild, Jan; Wilkinson, Dominic J C

2013-03-01

In this paper we outline the case for and against the treatment of idiopathic short stature with growth hormone. Drs Ambler and Fairchild argue that many of those with 'idiopathic' short stature are not 'short, normal children' and will ultimately receive molecular diagnoses. They also argue that there is a subset of children who suffer negative psychosocial consequences of their stature for whom growth hormone therapy is effective. Growth hormone has a very good safety record and is likely to be as cost-effective in idiopathic short-stature as in some other conditions that are currently funded. Dr Wilkinson counters that short stature is not associated with physical or psychological illness, and that there is no evidence that growth hormone improves psychological or physical wellbeing. Moreover, growth hormone for idiopathic short stature represents a form of enhancement rather than treatment, and is not a fair use of resources. Socially mediated disadvantage should be treated by attention to prejudice and not by hormone treatment. © 2012 The Authors.

Women receiving vitamin K antagonists (VKAs) require adequate contraception because of the potential for fetal complications. It is unknown whether the use of hormonal therapy, especially those containing estrogens, is associated with recurrent venous thromboembolism (VTE) during anticoagulation. Despite the absence of data, World Health Organization guidelines state that use of estrogen-containing contraceptives confers an “unacceptable health risk” during established anticoagulation for VTE. We compared the incidences of recurrent VTE and abnormal uterine bleeding with and without concomitant hormonal therapy in women aged <60 years who were receiving anticoagulation with rivaroxaban or enoxaparin/VKA for confirmed VTE. Incidence densities in percentage per year were computed for the on and off estrogen-containing or progestin-only therapy periods. Cox regression models were fitted, with hormonal therapy (on vs off) as a time-dependent variable to derive the hazard ratio (HR) for the effects on recurrent VTE and abnormal uterine bleeding. In total, 1888 women were included. VTE incidence densities on and off hormonal therapy were 3.7%/year and 4.7%/year (adjusted HR, 0.56; 95% confidence interval [CI], 0.23-1.39), respectively, and were 3.7%/year and 3.8%/year, respectively, for estrogen-containing and progestin-only therapy. The adjusted HR for all abnormal uterine bleeding (on vs off hormonal therapy) was 1.02 (95% CI, 0.66-1.57). Abnormal uterine bleeding occurred more frequently with rivaroxaban than with enoxaparin/VKA (HR, 2.13; 95% CI, 1.57-2.89). Hormonal therapy was not associated with an increased risk of recurrent VTE in women receiving therapeutic anticoagulation. The observed increased risk of abnormal uterine bleeding with rivaroxaban needs further exploration. PMID:26696010

Women receiving vitamin K antagonists (VKAs) require adequate contraception because of the potential for fetal complications. It is unknown whether the use of hormonal therapy, especially those containing estrogens, is associated with recurrent venous thromboembolism (VTE) during anticoagulation. Despite the absence of data, World Health Organization guidelines state that use of estrogen-containing contraceptives confers an "unacceptable health risk" during established anticoagulation for VTE. We compared the incidences of recurrent VTE and abnormal uterine bleeding with and without concomitant hormonal therapy in women aged <60 years who were receiving anticoagulation with rivaroxaban or enoxaparin/VKA for confirmed VTE. Incidence densities in percentage per year were computed for the on and off estrogen-containing or progestin-only therapy periods. Cox regression models were fitted, with hormonal therapy (on vs off) as a time-dependent variable to derive the hazard ratio (HR) for the effects on recurrent VTE and abnormal uterine bleeding. In total, 1888 women were included. VTE incidence densities on and off hormonal therapy were 3.7%/year and 4.7%/year (adjusted HR, 0.56; 95% confidence interval [CI], 0.23-1.39), respectively, and were 3.7%/year and 3.8%/year, respectively, for estrogen-containing and progestin-only therapy. The adjusted HR for all abnormal uterine bleeding (on vs off hormonal therapy) was 1.02 (95% CI, 0.66-1.57). Abnormal uterine bleeding occurred more frequently with rivaroxaban than with enoxaparin/VKA (HR, 2.13; 95% CI, 1.57-2.89). Hormonal therapy was not associated with an increased risk of recurrent VTE in women receiving therapeutic anticoagulation. The observed increased risk of abnormal uterine bleeding with rivaroxaban needs further exploration. © 2016 by The American Society of Hematology.

Few studies have assessed the role of cross-sex hormones on psychological outcomes during the period of hormonal therapy preceding sex reassignment surgery in transsexuals. The objective of this study was to assess the relationship between hormonal therapy, self-esteem, depression, quality of life (QoL), and global functioning. This study incorporated a cross-sectional design. The inclusion criteria were diagnosis of gender identity disorder (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) and inclusion in a standardized sex reassignment procedure. The outcome measures were self-esteem (Social Self-Esteem Inventory), mood (Beck Depression Inventory), QoL (Subjective Quality of Life Analysis), and global functioning (Global Assessment of Functioning). Sixty-seven consecutive individuals agreed to participate. Seventy-three percent received hormonal therapy. Hormonal therapy was an independent factor in greater self-esteem, less severe depression symptoms, and greater "psychological-like" dimensions of QoL. These findings should provide pertinent information for health care providers who consider this period as a crucial part of the global sex reassignment procedure.

AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY POSITION STATEMENT ON MENOPAUSE-2017 UPDATE.

PubMed

Cobin, Rhoda H; Goodman, Neil F

2017-07-01

EXECUTIVE SUMMARY This American Association of Clinical Endocrinologists (AACE)/American College of Endocrinology (ACE) Position Statement is designed to update the previous menopause clinical practice guidelines published in 2011 but does not replace them. The current document reviews new clinical trials published since then as well as new information regarding possible risks and benefits of therapies available for the treatment of menopausal symptoms. AACE reinforces the recommendations made in its previous guidelines and provides additional recommendations on the basis of new data. A summary regarding this position statement is listed below: New information available from randomized clinical trials and epidemiologic studies reported after 2011 was critically reviewed. No previous recommendations from the 2011 menopause clinical practice guidelines have been reversed or changed. Newer information enhances AACE's guidance for the use of hormone therapy in different subsets of women. Newer information helps to support the use of various types of estrogens, selective estrogen-receptor modulators (SERMs), and progesterone, as well as the route of delivery. Newer information supports the previous recommendation against the use of bioidentical hormones. The use of nonhormonal therapies for the symptomatic relief of menopausal symptoms is supported. Newer information enhances AACE's guidance for the use of hormone therapy in different subsets of women. Newer information helps to support the use of various types of estrogens, SERMs, and progesterone, as well as the route of delivery. Newer information supports the previous recommendation against the use of bioidentical hormones. The use of nonhormonal therapies for the symptomatic relief of menopausal symptoms is supported. New recommendations in this position statement include: 1. the use of menopausal hormone therapy in symptomatic postmenopausal women should be based on consideration of all risk factors for cardiovascular disease, age, and time from menopause. 2. the use of transdermal as compared with oral estrogen preparations may be considered less likely to produce thrombotic risk and perhaps the risk of stroke and coronary artery disease. 3. when the use of progesterone is necessary, micronized progesterone is considered the safer alternative. 4. in symptomatic menopausal women who are at significant risk from the use of hormone replacement therapy, the use of selective serotonin re-uptake inhibitors and possibly other nonhormonal agents may offer significant symptom relief. 5. AACE does not recommend use of bioidentical hormone therapy. 6. AACE fully supports the recommendations of the Comité de l'Évolution des Pratiques en Oncologie regarding the management of menopause in women with breast cancer. 7. HRT is not recommended for the prevention of diabetes. 8. In women with previously diagnosed diabetes, the use of HRT should be individualized, taking in to account age, metabolic, and cardiovascular risk factors.

The artificial pancreas is an emerging technology for the treatment of type 1 diabetes and two configurations have been proposed: single-hormone (insulin alone) and dual-hormone (insulin and glucagon). We aimed to delineate the usefulness of glucagon in the artificial pancreas system. We did a randomised crossover trial of dual-hormone artificial pancreas, single-hormone artificial pancreas, and conventional insulin pump therapy (continuous subcutaneous insulin infusion) in participants aged 12 years or older with type 1 diabetes. Participants were assigned in a 1:1:1:1:1:1 ratio with blocked randomisation to the three interventions and attended a research facility for three 24-h study visits. During visits when the patient used the single-hormone artificial pancreas, insulin was delivered based on glucose sensor readings and a predictive dosing algorithm. During dual-hormone artificial pancreas visits, glucagon was also delivered during low or falling glucose. During conventional insulin pump therapy visits, patients received continuous subcutaneous insulin infusion. The study was not masked. The primary outcome was the time for which plasma glucose concentrations were in the target range (4·0-10·0 mmol/L for 2 h postprandially and 4·0-8·0 mmol/L otherwise). Hypoglycaemic events were defined as plasma glucose concentration of less than 3·3 mmol/L with symptoms or less than 3·0 mmol/L irrespective of symptoms. Analysis was by modified intention to treat, in which we included data for all patients who completed at least two visits. A p value of less than 0·0167 (0·05/3) was regarded as significant. This trial is registered with ClinicalTrials.gov, number NCT01754337. The mean proportion of time spent in the plasma glucose target range over 24 h was 62% (SD 18), 63% (18), and 51% (19) with single-hormone artificial pancreas, dual-hormone artificial pancreas, and conventional insulin pump therapy, respectively. The mean difference in time spent in the target range between single-hormone artificial pancreas and conventional insulin pump therapy was 11% (17; p=0·002) and between dual-hormone artificial pancreas and conventional insulin pump therapy was 12% (21; p=0·00011). There was no difference (15; p=0·75) in the proportion of time spent in the target range between the single-hormone and dual-hormone artificial pancreas systems. There were 52 hypoglycaemic events with conventional insulin pump therapy (12 of which were symptomatic), 13 with the single-hormone artificial pancreas (five of which were symptomatic), and nine with the dual-hormone artificial pancreas (0 of which were symptomatic); the number of nocturnal hypoglycaemic events was 13 (0 symptomatic), 0, and 0, respectively. Single-hormone and dual-hormone artificial pancreas systems both provided better glycaemic control than did conventional insulin pump therapy. The single-hormone artificial pancreas might be sufficient for hypoglycaemia-free overnight glycaemic control.

Introduction Although hormonal-therapy is the preferred first-line treatment for hormone-responsive, HER2 negative metastatic breast cancer, no data from clinical trials support the choice between hormonal-therapy and chemotherapy.Methods Patients were divided into two groups according to the treatment: chemotherapy or hormonal-therapy. Outcomes in terms of clinical benefit and median overall survival (OS) were retrospectively evaluated in the two groups. To calculate the time spent in chemotherapy with respect to OS in the two groups, the proportion of patients in chemotherapy relative to those present in either group was computed at every day from the start of therapy.Results From 1999 to 2013, 119 patients received first-line hormonal-therapy (HT-first group) and 100 first-line chemotherapy (CT-first group). Patients in the CT-first group were younger and with poorer prognostic factors as compared to those in HT-first group. Clinical benefit (77 vs 81%) and median OS (50.7 vs 51.1 months) were similar in the two groups. Time spent in chemotherapy was significantly longer during the first 3 years in CT-first group (54-34%) as compared to the HT-first group (11-18%). This difference decreased after the third year and overall was 28% in the CT-first group and 18% in the HT-first group.Conclusions The sequence first-line chemotherapy followed by hormonal-therapy, as compared with the opposite sequence, is associated with a longer time of OS spent in chemotherapy. However, despite the poorer prognostic factors, patients in the CT-first group had a superimposable OS than those in the HT-first group.

Background The risks/benefits balance of hormone replacement therapy is controversial. Information can influence consumers' knowledge and behavior; research findings about hormone replacement therapy are uncertain and the messages provided by the media are of poor quality and incomplete, preventing a fully informed decision making process. We therefore felt that an explicit, rigorous and structured assessment of the information needs on this issue was urgent and we opted for the organisation of a national consensus conference (CC) to assess the current status of the quality of information on hormone replacement therapy (HRT) and re-visit recent research findings on its risks/benefits. Methods We chose a structured approach based on the traditional CC method combined with a structured preparatory work supervised by an organising committee (OC) and a scientific board (SB). The OC and SB chose the members of the CC's jury and appointed three multidisciplinary working groups (MWG) which were asked to review clinical issues and different aspects of the quality of information. Before the CC, the three MWGs carried out: a literature review on the risk/benefit profile of HRT and two surveys on the quality of information on lay press and booklets targeted to women. A population survey on women's knowledge, attitude and practice was also carried out. The jury received the documents in advance, listened the presentations during the two-day meeting of the CCs, met immediately after in a closed-door meeting and prepared the final document. Participants were researchers, clinicians, journalists as well as consumers' representatives. Results Key messages in the CC's deliberation were: a) women need to be fully informed about the transient nature of menopausal symptoms, about HRT risks and benefits and about the availability of non-pharmacological interventions; b) HRT is not recommended to prevent menopausal symptoms; c) the term "HRT" is misleading and "post menopausal hormone therapy" should be the preferred definition. Conclusion This CC led to the identification of specific information drawbacks. Women are exposed to messages that are often partial, non evidence-based nor transparently developed. The structured and participative methodology of this CC allowed a multidisciplinary perspective and a substantial lay people input. PMID:19480688

Repeated application of GnRH agonists causes a reversible suppression of ovarian function. Suppression on estrogen release is the fundamental idea of this hormonal therapy of endometriosis. We treated twelve patients with histologically proved endometriosis with leuprolide acetate depot in a dose of 3.75 mg s.c. every 4 weeks over a period of 6 months. In the first week of therapy the estrogen level decreased to a post-menopausal niveau along with amenorrhoea during the entire period of therapy. Complaints previous to therapy such as dysmenorrhoea, pelvic pain and dyspareunia were relieved or completely disappeared after therapy. The clinical finding on palpation also diminished or disappeared. In addition to this finding pelvis copy showed a shift from severe endometriosis stage III and stage IV to stage I and stage II of the AFS classification 1985. Regular menstruation appeared in 5 to 9 weeks after the last application to all patients. Out of six cases of infertility, four patients became pregnant. Except for one case, typical menopausal symptoms appeared, such as flush, increased perspiration and sleeping disorders. During and after therapy we could not prove any changes in the lipid metabolism under estrogen therapy. Mineralization of the bone decreased under therapy by about 3%. Simultaneously, serum osteocalcin increased. Demineralization occurred with one exception within the normal range for the corresponding age. With identical efficiency but less side effects, we see therapy with GnRH agonists as an alternative to current hormonal therapy of endometriosis.

In most cases, about the voice of the patient with female-to-male/gender identity disorder (FTM/GID), hormone therapy makes the voice low-pitched. In success cases, there is no need for phonosurgery. However, hormone therapy is not effective in some cases. We perform type 3 thyroplasty in these cases. Hormone therapy was started in 2008 but did not lower the speaking fundamental frequencies (SFFs). We therefore performed TP3 under local anesthesia. In our case, the SFF at the first visit was 146 Hz. The postoperative SFF was 110 Hz. TP3 was performed under local anesthesia in a patient with FTM/GID in whom hormone therapy proved ineffective. With successful conversion to a lower-pitched voice, the patient could begin to live daily life as a male. QOL improved significantly with TP3. If hormone therapy proves ineffective, TP3 may be selected as an optional treatment and appears to show few surgical complications and was, in this case, a very effective treatment.

Navigation through inter- and intratumoral heterogeneity of endocrine resistance mechanisms in breast cancer: A potential role for Liquid Biopsies?

PubMed

Reinhardt, Florian; Franken, André; Fehm, Tanja; Neubauer, Hans

2017-11-01

The majority of breast cancers are hormone receptor positive due to the expression of the estrogen and/or progesterone receptors. Endocrine therapy is a major treatment option for all disease stages of hormone receptor-positive breast cancer and improves overall survival. However, endocrine therapy is limited by de novo and acquired resistance. Several factors have been proposed for endocrine therapy failures, which include molecular alterations in the estrogen receptor pathway, altered expression of cell-cycle regulators, autophagy, and epithelial-to-mesenchymal transition as a consequence of tumor progression and selection pressure. It is essential to reveal and monitor intra- and intertumoral alterations in breast cancer to allow optimal therapy outcome. Endocrine therapy navigation by molecular profiling of tissue biopsies is the current gold standard but limited in many reasons. "Liquid biopsies" such as circulating-tumor cells and circulating-tumor DNA offer hope to fill that gap in allowing non-invasive serial assessment of biomarkers predicting success of endocrine therapy regimen. In this context, this review will provide an overview on inter- and intratumoral heterogeneity of endocrine resistance mechanisms and discuss the potential role of "liquid biopsies" as navigators to personalize treatment methods and prevent endocrine treatment resistance in breast cancer.

Introduction Current and recent users of hormone replacement therapy (HRT) have an increased risk of being recalled to assessment at mammography without breast cancer being diagnosed ('false positive recall'), but there is limited information on the effects of different patterns of HRT use on this. The aim of this study is to investigate in detail the relationship between patterns of use of HRT and false positive recall. Methods A total of 87,967 postmenopausal women aged 50 to 64 years attending routine breast cancer screening at 10 UK National Health Service Breast Screening Units from 1996 to 1998 joined the Million Women Study by completing a questionnaire before screening and were followed for their screening outcome. Results Overall, 399 (0.5%) participants were diagnosed with breast cancer and 2,629 (3.0%) had false positive recall. Compared to never users of HRT, the adjusted relative risk (95% CI) of false positive recall was: 1.62 (1.43–1.83), 1.80 (1.62–2.01) and 0.76 (0.52–1.10) in current users of oestrogen-only HRT, oestrogen-progestagen HRT and tibolone, respectively (p (heterogeneity) < 0.0001); 1.65 (1.43–1.91), 1.49 (1.22–1.81) and 2.11 (1.45–3.07) for current HRT used orally, transdermally or via an implant, respectively (p (heterogeneity) = 0.2); and 1.84 (1.67–2.04) and 1.75 (1.49–2.06) for sequential and continuous oestrogen-progestagen HRT, respectively (p (heterogeneity) = 0.6). The relative risk of false positive recall among current users appeared to increase with increasing time since menopause, but did not vary significantly according to any other factors examined, including duration of use, hormonal constituents, dose, whether single- or two-view screening was used, or the woman's personal characteristics. Conclusion Current use of oestrogen-only and oestrogen-progestagen HRT, but not tibolone, increases the risk of false positive recall at screening. PMID:16417651

Could the improvement of obesity-related co-morbidities depend on modified gut hormones secretion?

Obesity and its associated diseases are a worldwide epidemic disease. Usual weight loss cures - as diets, physical activity, behavior therapy and pharmacotherapy - have been continuously implemented but still have relatively poor long-term success and mainly scarce adherence. Bariatric surgery is to date the most effective long term treatment for morbid obesity and it has been proven to reduce obesity-related co-morbidities, among them nonalcoholic fatty liver disease, and mortality. This article summarizes such variations in gut hormones following the current metabolic surgery procedures. The profile of gut hormonal changes after bariatric surgery represents a strategy for the individuation of the most performing surgical procedures to achieve clinical results. About this topic, experts suggest that the individuation of the crosslink among the gut hormones, microbiome, the obesity and the bariatric surgery could lead to new and more specific therapeutic interventions for severe obesity and its co-morbidities, also non surgical.

The pituitary gland plays a key role in hormonal regulation in the organism, contributing to maintenance of balance of basic vital functions. To emphasise the need for assessment of pituitary function after head injury, as correct diagnosis and hormone replacement therapy prove to be a life-saving therapy accelerating the recovery process. A healthy, normally developing 9-year-old girl, a child of young and healthy parents, was struck by a falling tree. The results of severe head trauma included adrenal crisis, hypothyroidism, and diabetes insipidus as manifestations of damage to the anterior and posterior pituitary gland. Administration of hormone replacement therapy, i.e. hydrocortisone, L-thyroxine, and desmopressin greatly improved the patient´s condition and facilitated effective rehabilitation. Determination of pituitary hormones in children after severe head injury should be an important part of diagnosis allowing identification of an early stage of acute hypopituitarism and acceleration of recovery through hormone replacement therapy.

Whether women developing venous thromboembolism (VTE) while using hormonal therapy should be classified as having "unprovoked" or "provoked" VTE is controversial. We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the rate of symptomatic VTE recurrences after discontinuing anticoagulation in 3 subgroups of women aged ≤50years without cancer, pregnancy or puerperium: (1) those with hormonal therapy and no additional risk factors (hormonal users only); (2) those with unprovoked VTE; and (3) those with additional risk factors, with or without hormonal therapy. As of March 2016, 1513 women had been followed-up for at least one month after discontinuing anticoagulation. Of these, 654 (43%) were hormonal users only, 390 (26%) had unprovoked VTE and 469 (31%) had transient risk factors with or without hormonal therapy. After discontinuing anticoagulation, the rate of VTE recurrences in women with hormonal use only (2.44 per 100 patient-years; 95% CI: 1.53-3.69) was significantly lower than in those with unprovoked VTE (6.03; 95% CI: 3.97-8.77) and similar to those with transient risk factors (2.58; 95% CI: 1.50-4.13). Interestingly, the rate of VTE recurrences presenting as pulmonary embolism in women with hormonal use only (0.55 per 100 patient-years; 95% CI: 0.18-1.29) was similar to those with transient risk factors (0.46; 95% CI: 0.09-1.33) and 4-fold lower than in women with unprovoked VTE (2.23; 95% CI: 1.07-4.10). After discontinuing anticoagulation, the rate of VTE recurrences in hormonal users only was significantly lower than in women with unprovoked VTE and similar to the rate in women with additional risk factors. © 2017 Elsevier Ltd.

Although the impact of sex reassignment surgery on the self-reported outcomes of transsexuals has been largely described, the data available regarding the impact of hormone therapy on the daily lives of these individuals are scarce. The objectives of this study were to assess the relationship between hormonal therapy and the self-reported quality of life (QoL) in transsexuals while taking into account the key confounding factors and to compare the QoL levels between transsexuals who have, vs. those who have not, undergone cross-sex hormone therapy as well as between transsexuals and the general population (French age- and sex-matched controls). This study incorporated a cross-sectional design that was conducted in three psychiatric departments of public university teaching hospitals in France. The inclusion criteria were as follows: 18 years or older, diagnosis of gender identity disorder (302.85) according to the Diagnostic and Statistical Manual, fourth edition text revision (DSM-IV TR), inclusion in a standardized sex reassignment procedure following the agreement of a multidisciplinary team, and pre-sex reassignment surgery. QoL was assessed using the Short Form 36 (SF-36). The mean age of the total sample was 34.7 years, and the sex ratio was 1:1. Forty-four (72.1%) of the participants received hormonal therapy. Hormonal therapy and depression were independent predictive factors of the SF-36 mental composite score. Hormonal therapy was significantly associated with a higher QoL, while depression was significantly associated with a lower QoL. Transsexuals' QoL, independently of hormonal status, did not differ from the French age- and sex-matched controls except for two subscales of the SF-36 questionnaire: role physical (lower scores in transsexuals) and general health (lower scores in controls). The present study suggests a positive effect of hormone therapy on transsexuals' QoL after accounting for confounding factors. These results will be useful for healthcare providers of transgender persons but should be confirmed with larger samples using a prospective study design. © 2011 International Society for Sexual Medicine.

Pubertal induction in hypogonadism: Current approaches including use of gonadotrophins.

2015-06-01

Primary disorders of the gonad or those secondary to abnormalities of the hypothalamic pituitary axis result in hypogonadism. The range of health problems of childhood and adolescence that affect this axis has increased, as most children now survive chronic illness, but many have persisting deficits in gonadal function as a result of their underlying condition or its treatment. An integrated approach to hormone replacement is needed to optimize adult hormonal and bone health, and to offer opportunities for fertility induction and preservation that were not considered possible in the past. Timing of presentation ranges from birth, with disorders of sexual development, through adolescent pubertal failure, to adult fertility problems. This review addresses diagnosis and management of hypogonadism and focuses on new management strategies to address current concerns with fertility preservation. These include Turner syndrome, and fertility presevation prior to childhood cancer treatment. New strategies for male hormone replacement therapy that may impinge upon future fertility are emphasized. Copyright © 2015 Elsevier Ltd. All rights reserved.

2005-04-01

This study examined the impact of sex hormones on functional cerebral hemispheric lateralization and cognition in a group of male-to-female transsexuals receiving cross-sex hormone therapy compared to eugonadal men with a male gender identity. Cerebral lateralization was measured with a handedness questionnaire and a visual-split-field paradigm and cognitive tests sensitive to sex hormone exposure (identical pictures, 3-D mental rotation, building memory) were also administered. Endocrine measures on the day of participation for transsexual and control subjects included total testosterone, free testosterone, estradiol, gonadotropins, and sex hormone binding globulin concentrations. Compared to controls, male-to-female transsexuals had elevated estradiol and sex hormone binding globulin concentrations and suppressed testosterone concentrations. Transsexual subjects showed a trend toward less exclusive right-handedness than controls. No group differences were observed on the visual-split-field or cognitive tasks. No direct associations were observed between endocrine measures and the laterality measures and cognitive performance. Previous observations of female-typical patterns in cerebral lateralization and cognitive performance in male-to-female transsexuals were not found in the current study.

Human ageing is accompanied with deterioration in endocrine functions the most notable and well characterized of which being the decrease in the production of sex hormones. Current research literature suggests that low sex hormone concentration may be among the key mechanism for sarcopenia and muscle weakness. Within the European large scale MYOAGE project, the role of sex hormones, estrogens and testosterone, in causing the aging-related loss of muscle mass and function was further investigated. Hormone replacement therapy (HRT) in women is shown to diminish age-associated muscle loss, loss in fast muscle function (power), and accumulation of fat in skeletal muscle. Further HRT raises the protein synthesis rate in skeletal muscle after resistance training, and has an anabolic effect upon connective tissue in both skeletal muscle and tendon, which influences matrix structure and mechanical properties. HRT influences gene expression in e.g. cytoskeletal and cell-matrix proteins, has a stimulating effect upon IGF-I, and a role in IL-6 and adipokine regulation. Despite low circulating steroid-hormone level, postmenopausal women have a high local concentration of steroidogenic enzymes in skeletal muscle.

The accrual of healthy bone during the critical period of childhood and adolescence sets the stage for lifelong skeletal health. However, in children with chronic kidney disease (CKD), disturbances in mineral metabolism and endocrine homeostasis begin early on, leading to alterations in bone turnover, mineralization, and volume, and impairing growth. Risk factors for CKD–mineral and bone disorder (CKD–MBD) include nutritional vitamin D deficiency, secondary hyperparathyroidism, increased fibroblast growth factor 23 (FGF-23), altered growth hormone and insulin-like growth factor-1 axis, delayed puberty, malnutrition, and metabolic acidosis. After kidney transplantation, nutritional vitamin D deficiency, persistent hyperparathyroidism, tertiary FGF-23 excess, hypophosphatemia, hypomagnesemia, immunosuppressive therapy, and alteration of sex hormones continue to impair bone health and growth. As function of the renal allograft declines over time, CKD–MBD associated changes are reactivated, further impairing bone health. Strategies to optimize bone health post-transplant include healthy diet, weight-bearing exercise, correction of vitamin D deficiency and acidosis, electrolyte abnormalities, steroid avoidance, and consideration of recombinant human growth hormone therapy. Other drug therapies have been used in adult transplant recipients, but there is insufficient evidence for use in the pediatric population at the present time. Future therapies to be explored include anti-FGF-23 antibodies, FGF-23 receptor blockers, and treatments targeting the colonic microbiota by reduction of generation of bacterial toxins and adsorption of toxic end products that affect bone mineralization.

Untreated transgender men face serious negative health care outcomes. Effective medical, surgical, and mental health treatment ameliorates these risks. Although the research is not as robust as would be ideal, hormone treatment is effective and generally well tolerated with few serious medical risks. Surgeries carry serious risks; but for most transgender men, the benefits outweigh the risks. This review describes current evidence-based medical treatments for transgender men and provides an overview of surgical therapy to enable practitioners to discuss these options with their transgender male patients.

Objective Although estrogen may be linked to biological pathways that maintain higher physical function, the evidence is derived mostly from observational epidemiology and therefore has numerous limitations. We examined whether hormone therapy affected physical function in women 65 to 79 years of age at enrollment. Methods This study involves an analysis of the Women’s Health Initiative randomized controlled trials of hormone therapy in which 922 nondisabled women who had previous hysterectomies were randomized to receive estrogen therapy or a placebo and 1,458 nondisabled women with intact uteri were randomized to receive estrogen + progestin therapy or a placebo. Changes in physical function were analyzed for treatment effect, and subgroup differences were evaluated. All women completed performance-based measures of physical function (grip strength, chair stands, and timed walk) at baseline. These measures were repeated after 1, 3, and 6 years. Results Overall, participants’ grip strength declined by 12.0%, chair stands declined by 3.5%, and walk pace slowed by 11.4% in the 6 years of follow-up (all P values <0.0001). Hormone therapy, as compared with placebo, was not associated with an increased or decreased risk of decline in physical function in either the intention-to-treat analyses or in analyses restricted to participants who were compliant in taking study pills. Conclusions Hormone therapy provided no overall protection against functional decline in nondisabled postmenopausal women 65 years or older in 6 years of follow-up. This study did not address the influence of hormone therapy for women of younger ages. PMID:19858764

This study aims to explore the effects of menopause and hormone therapy on the symptoms and signs of stress urinary incontinence and urge urinary incontinence. Records of women who attended a tertiary urogynecological unit were reviewed retrospectively. A standardized interview included evaluations of symptoms, menopause age (ie, time since last menstrual period or onset of menopausal symptoms), current or previous hormone use, and visual analogue scales for bother. Multichannel urodynamics, including urethral pressure profilometry and determination of abdominal leak point pressure, was performed. Of 382 women seen during the inclusion period, 62% were postmenopausal. Current systemic or local hormone use was reported by 7% and 6%, respectively. Two hundred eighty-eight women (76%) reported symptoms of stress urinary incontinence, with a mean bother of 5.7, and 273 women (72%) reported symptoms of urge urinary incontinence, with a mean bother of 6.4. On univariate analysis, symptoms and bother of urge incontinence were significantly related to menopause age, whereas this relationship was not found for stress incontinence. After calendar age was controlled for, length of menopause showed no significant relationship with any symptom or sign of urinary incontinence. Hormone deficiency after menopause is unlikely to play a major role in urinary incontinence.

CDK4/6 Inhibitors: Game Changers in the Management of Hormone Receptor–Positive Advanced Breast Cancer?

PubMed

Shah, Mirat; Nunes, Maria Raquel; Stearns, Vered

2018-05-15

The cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors palbociclib, ribociclib, and abemaciclib are rapidly transforming the care of patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative (HR+/HER2-) advanced breast cancer. Current clinical questions include how to choose among these agents and how to sequence them with other therapies. Areas of active inquiry include identifying predictive biomarkers for CDK4/6 inhibitors, deciding whether to continue CDK4/6 inhibitors after disease progression, creating novel treatment combinations, and expanding use beyond HR+/HER2- advanced breast cancer. Here, we review the current use of and potential next directions for CDK4/6 inhibitors in the treatment of patients with HR+ breast cancer.

Differentiated thyroid cancer is the most common malignant carcinoma in female population.Postoperative long-term thyroid-stimulating hormone(TSH) suppression therapy can reduce the risk of recurrence for differentiated thyroid cancer and control the progress of the disease, but it also induces simultaneously subclinical hypothyroidism and imposes negative effect on female. In addition to cardiovascular disease, TSH suppression therapy can lead to the alteration of sex hormone metabolism, menstrual disorder, poor influence on pregnancy and osteoporosis. This article reviews the recent studies on postoperative TSH suppression therapy in women with thyroid cancer.

Hormonal development therapy (HDT) in hypogonadism in long-term view.

PubMed

Heinz, Marlene

2010-04-01

Since the 1960s, oestrogen deficiency in hypogonadism in girls has been successfully treated by a sort of analogous application of the menopausal hormone replacement therapy (HRT) scheme, here however, to induce and support sexual development in puberty and adolescence. The essential distinction between goals, ways and means of the two distinct hormonal treatments caused by menopause and by hypogonadism in puberty also suggests that the latter treatment is more characteristic of defining hormonal development therapy (HDT). Moreover, specific HDT in hypogonadism is essential for longitudinal growth of girls, functions of female reproductive system, bone and lipid metabolism and the immune, central nervous and cardiovascular systems. By contrast, the aim of menopausal replacement therapy in elderly women is treating negative effects of physiological loss of oestrogens as hot flush, lacks of female well-being and osteoporosis, while in hypogonadal girls there is of course nothing that might be replaced eventually. Especially in cases of absolute oestrogen deficiency, as in Turner syndrome and in other cases of premature ovarian failure, HDT has to be started at the age of expected puberty. An international consensus suggests possibly lifelong HDT for the lasting support of female development and functions. However, neither reliable studies about possible risks and side effects of continuous hormonal therapy in adult women with hypogonadismus nor a more precise consensus have emerged yet. Emphasising the term HDT particularly aims at putting more effort in getting over these paucities simultaneously. Indications, hormonal therapy, dosage, application and timing in puberty are described in this article. Aspects of long-term hormonal treatment are critically discussed. Copyright 2010 Elsevier Ltd.

Progesterone is a steroid hormone of essential role in reproduction. In early pregnancy, it is responsible for preparation of endometrium for implantation process and maintenance of gestational sac in uterus, also by modulation of maternal immune system. Even though, several indices has been proposed as markers of endogenous progesterone synthesis (progesterone or luteinizing hormone measurements, endometrial biopsy), none has been proved to be reliable in detecting luteal phase defect. Currently, several pharmaceutical formulations are available, but in clinical setting the non-oral formulations seems to be effective in therapy. Progesterone is effective in the treatment of patients undergoing assisted reproductive technology procedure, as a luteal phase support. Some studies showed also its efficacy in the treatment of threatening or recurrent miscarriage, but newer trials neglected this beneficial effect. Due to controversies regarding utility of progesterone supplementation in these conditions, further studies are needed to address this issue.

The growth hormone (GH)-insulin-like growth factor (IGF)-I axis is a key endocrine mechanism regulating linear growth in children. While paediatricians have a good knowledge of GH secretion and assessment, understanding and use of measurements of the components of the IGF system are less current in clinical practice. The physiological function of this axis is to increase the anabolic cellular processes of protein synthesis and mitosis, and reduction of apoptosis, with each being regulated in the appropriate target tissue. Measurement of serum IGF-I and IGFBP-3 concentrations can complement assessment of GH status in the investigation of short stature and contribute to prediction of growth response during GH therapy. IGF-I monitoring during GH therapy also informs the clinician about adherence and provides a safety reference to avoid over-dosing during long-term management.

The pituitary glycoprotein hormones, luteinizing hormone and follicle-stimulating hormone (FSH), act through their cognate receptors to initiate a series of coordinated physiological events that results in germ cell maturation. Given the importance of FSH in regulating folliculogenesis and fertility, the development of FSH mimetics has been sought to treat infertility. Currently, purified and recombinant human FSH are the only FSH receptor (FSH-R) agonists available for infertility treatment. By screening unbiased combinatorial chemistry libraries, using a cAMP-responsive luciferase reporter assay, we discovered thiazolidinone agonists (EC50's = 20 microm) of the human FSH-R. Subsequent analog library screening and parallel synthesis optimization resulted in the identification of a potent agonist (EC50 = 2 nm) with full efficacy compared with FSH that was FSH-R-selective and -dependent. The compound mediated progesterone production in Y1 cells transfected with the human FSH-R (EC50 = 980 nm) and estradiol production from primary rat ovarian granulosa cells (EC50 = 10.5 nm). This and related compounds did not compete with FSH for binding to the FSH-R. Use of human FSH/thyroid-stimulating hormone (TSH) receptor chimeras suggested a novel mechanism for receptor activation through a binding site independent of the natural hormone binding site. This study is the first report of a high affinity small molecule agonist that activates a glycoprotein hormone receptor through an allosteric mechanism. The small molecule FSH receptor agonists described here could lead to an oral alternative to the current parenteral FSH treatments used clinically to induce ovarian stimulation for both in vivo and in vitro fertilization therapy.

Menopause occurs at a median age of 51.3 years, and the average US woman who reaches menopause is expected to live another 30 years. The prevalence and incidence of most chronic conditions, such as coronary heart disease, dementia, stroke, fractures, and breast cancer, increase with age; however, the excess risk for these conditions that can be attributed to menopause alone is uncertain. Since the publication of findings from the Women's Health Initiative that hormone therapy use is associated with serious adverse health effects in postmenopausal women, use of menopausal hormone therapy has declined. To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on the use of menopausal hormone therapy for the primary prevention of chronic conditions. The USPSTF reviewed the evidence on the benefits and harms of systemic (ie, oral or transdermal) hormone therapy for the prevention of chronic conditions in postmenopausal women and whether outcomes vary among women in different subgroups or by timing of intervention after menopause. The review did not address hormone therapy for preventing or treating menopausal symptoms. Although the use of hormone therapy to prevent chronic conditions in postmenopausal women is associated with some benefits, there are also well-documented harms. The USPSTF determined that the magnitude of both the benefits and the harms of hormone therapy in postmenopausal women is small to moderate. Therefore, the USPSTF concluded with moderate certainty that combined estrogen and progestin has no net benefit for the primary prevention of chronic conditions for most postmenopausal women with an intact uterus and that estrogen alone has no net benefit for the primary prevention of chronic conditions for most postmenopausal women who have had a hysterectomy. The USPSTF recommends against the use of combined estrogen and progestin for the primary prevention of chronic conditions in postmenopausal women. (D recommendation) The USPSTF recommends against the use of estrogen alone for the primary prevention of chronic conditions in postmenopausal women who have had a hysterectomy. (D recommendation).

Beer is one of the most frequently consumed fermented beverages in the world, and it has been part of the human diet for thousands of years. Scientific evidence obtained from the development of new techniques of food analysis over the last two decades suggests that polyphenol intake derived from moderate beer consumption may play a positive role in different health outcomes including osteoporosis and cardiovascular risk and the relief of vasomotor symptoms, which are commonly experienced during menopause and are an important reason why women seek medical care during this period; here, we review the current knowledge regarding moderate beer consumption and its possible effects on menopausal symptoms. The effect of polyphenol intake on vasomotor symptoms in menopause may be driven by the direct interaction of the phenolic compounds present in beer, such as 8-prenylnaringenin, 6-prenylnaringenin, and isoxanthohumol, with intracellular estrogen receptors that leads to the modulation of gene expression, increase in sex hormone plasma concentrations, and thus modulation of physiological hormone imbalance in menopausal women. Since traditional hormone replacement therapies increase health risks, alternative, safer treatment options are needed to alleviate menopausal symptoms in women. The present work aims to review the current data on this subject. PMID:28904736

European Code against Cancer 4th Edition: Medical exposures, including hormone therapy, and cancer.

The 4th edition of the European Code against Cancer recommends limiting - or avoiding when possible - the use of hormone replacement therapy (HRT) because of the increased risk of cancer, nevertheless acknowledging that prescription of HRT may be indicated under certain medical conditions. Current evidence shows that HRT, generally prescribed as menopausal hormone therapy, is associated with an increased risk of cancers of the breast, endometrium, and ovary, with the risk pattern depending on factors such as the type of therapy (oestrogen-only or combined oestrogen-progestogen), duration of treatment, and initiation according to the time of menopause. Carcinogenicity has also been established for anti-neoplastic agents used in cancer therapy, immunosuppressants, oestrogen-progestogen contraceptives, and tamoxifen. Medical use of ionising radiation, an established carcinogen, can provide major health benefits; however, prudent practices need to be in place, with procedures and techniques providing the needed diagnostic information or therapeutic gain with the lowest possible radiation exposure. For pharmaceutical drugs and medical radiation exposure with convincing evidence on their carcinogenicity, health benefits have to be balanced against the risks; potential increases in long-term cancer risk should be considered in the context of the often substantial and immediate health benefits from diagnosis and/or treatment. Thus, apart from HRT, no general recommendations on reducing cancer risk were given for carcinogenic drugs and medical radiation in the 4th edition of European Code against Cancer. It is crucial that the application of these measures relies on medical expertise and thorough benefit-risk evaluation. This also pertains to cancer-preventive drugs, and self-medication with aspirin or other potential chemopreventive drugs is strongly discouraged because of the possibility of serious, potentially lethal, adverse events.

[Glucocorticoid induced osteoporosis].

PubMed

Anić, Branimir; Mayer, Miroslav

2014-01-01

Secondary osteoporosis most often develops due to glucocorticoid therapy. Glucocorticoids affect all stages of the bone remodeling cycle, its formation and resorption. Osteoblasts are primarily affected, decreasing their activity and enhancing apoptosis. Patients treated with glucocorticoids have lower bone mineral density and increased fracture risk. Glucocorticoid-induced osteoporosis can be prevented by administering the minimal effective dose of glucocorticoids, calcium and vitamin D supplementation or, if possible, by hormone replace- ment therapy. Moreover, appropriate physical activity should be encouraged. Patients who are at higher risk for low-energy fractures (for example post-menopausal women) have to be actively treated, usually with antiresorptive drugs among which bisphosphonates are currently the first line therapy.

Current and emerging therapies for Addison's disease.

PubMed

Napier, Catherine; Pearce, Simon H S

2014-06-01

The purpose of this article is to review the current therapy of Addison's disease and to highlight recent developments in this field. Conventional steroid replacement for Addison's disease consists of twice or three-times daily oral hydrocortisone and once-daily fludrocortisone; however, new treatment modalities such as modified-released hydrocortisone and continuous subcutaneous hydrocortisone infusion have recently been developed. These offer the potential for closer simulation of the physiological serum cortisol rhythm. Two studies have also looked at modifying the natural history of adrenal failure using adrenocorticotropic hormone (ACTH) stimulation and immunomodulatory therapies, leading to the concept of residual adrenal function in some Addison's disease patients. Following more than 60 years with no significant innovation in the management of Addison's disease, these new approaches hold promise for improved patient health and better quality of life in the future.

New trends in combined use of gonadotropin-releasing hormone antagonists with gonadotropins or pulsatile gonadotropin-releasing hormone in ovulation induction and assisted reproductive technologies.

1992-10-01

The use of gonadotropin-releasing hormone agonists as adjunctive therapy with gonadotropins for ovulation induction in in vitro fertilization and other assisted reproductive technologies has become common clinical practice. With the recent advent of potent gonadotropin-releasing hormone antagonists free from the marked histamine-release effects that stymied earlier compounds, an attractive alternative method may be available. We have established the feasibility of combining gonadotropin-releasing hormone antagonist-induced inhibition of endogenous gonadotropins with exogenous gonadotropin therapy for ovulation induction in a nonhuman primate model. Here, the principal benefits to be gained from using the gonadotropin-releasing hormone antagonist rather than the gonadotropin-releasing hormone agonist are the immediate inhibition of pituitary gonadotropin secretion without the "flare effect," which brings greater safety and convenience for patients and the medical team and saves time and money. We have also recently demonstrated the feasibility of combining gonadotropin-releasing hormone antagonist with pulsatile gonadotropin-releasing hormone therapy for the controlled restoration of gonadotropin secretion and gonadal steroidogenesis culminating in apparently normal (singleton) ovulatory cycles. This is feasible only with gonadotropin-releasing hormone antagonists because, unlike gonadotropin-releasing hormone agonists, they achieve control of the pituitary-ovarian axis without down regulation of the gonadotropin-releasing hormone receptor system. This capacity to override gonadotropin-releasing hormone antagonist-induced suppression of pituitary-ovarian function may allow new treatment modalities to be employed for women who suffer from chronic hyperandrogenemia with polycystic ovarian disease.

In these clinical practice guidelines, specific recommendations are made for determining the most effective methods of diagnosing and treating hypogonadism in adult male patients. The target populations for these guidelines include the following: (1) men with primary testicular failure requiring testosterone replacement (hypergonadotropic hypogonadism); (2) male patients with gonadotropin deficiency or dysfunction who may have received testosterone replacement therapy or treatment for infertility (hypogonadotropic hypogonadism); and (3) aging men with symptoms relating to testosterone deficiency who could benefit from testosterone replacement therapy. Initial hormonal evaluation generally consists of a testosterone determination, in conjunction with a free testosterone or sex hormone-binding globulin level, inpatients with clear symptoms and signs but normal-range total testosterone, follicle-stimulating hormone, luteinizing hormone, and prolactin levels. Other possible tests include semen analysis, pituitary imaging studies, genetic studies, bone densitometry, testicular ultrasonography,testicular biopsy, and specialized hormonal dynamic testing. Therapeutic options generally consist of testosterone replacement by injections, patches, or topically applied gel in hypergonadotropic patients and in hypogonadotropic patients not interested in fertility. In hypogonadotropic patients interested in fertility, gonadal stimulation option scan be considered, including human chorionic gonadotropin stimulation therapy with or without human menopausal gonadotropin (or follicle-stimulating hormone) or gonadotropin-releasing hormone pump therapy. These therapies may be combined with assisted reproductive technologies such as in vitro fertilization with intracytoplasmic sperm injection, which may allow pregnancy to occur with very low numbers of sperm.

Noncontraceptive use of oral combined hormonal contraceptives in polycystic ovary syndrome-risks versus benefits.

PubMed

Dokras, Anuja

2016-12-01

The use of steroid sex hormones for noncontraceptive benefits has been endorsed by several medical societies. In women with polycystic ovary syndrome (PCOS), hormonal contraceptives are first-line therapy for concurrent treatment of menstrual irregularity, acne, and hirsutism. The association of PCOS with obesity, diabetes, and dyslipidemia frequently brings up the debate regarding risks versus benefits of hormonal contraceptives in this population. In women with PCOS, the lack of large-scale studies evaluating the risks with varying doses of ethinyl estradiol, types of progestins, and presence of confounding factors such as obesity, smoking, and other cardiometabolic comorbidities is a significant limitation in these deliberations. Although it is important to assess the absolute risk for major morbidities including cardiovascular events, currently, there are a paucity of long-term data for these outcomes in PCOS. Most of the current studies do not suggest an increase in risk of prediabetes/diabetes, clinically significant dyslipidemia, inflammatory changes, or depressive/anxiety symptoms with oral contraceptive pill use. Screening of women with PCOS for cardiometabolic and psychiatric comorbidities is routinely recommended. This information should be used by health care providers to individualize the choice of hormonal contraceptive treatment, adequately counsel patients regarding risks and benefits, and formulate an appropriate follow-up plan.

2017-08-01

The pituitary gland is one of the key components of the endocrine system. Congenital or acquired alterations can mediate destruction of cells in the gland leading to hormonal dysfunction. Even though pharmacological treatment for pituitary disorders is available, exogenous hormone replacement is neither curative nor sustainable. Thus, alternative therapies to optimize management and improve quality of life are desired. An alternative modality to re-establish pituitary function is to promote endocrine cell regeneration through stem cells that can be obtained from the pituitary parenchyma or pluripotent cells. Stem cell therapy has been successfully applied to a plethora of other disorders, and is a promising alternative to hormonal supplementation for resumption of normal hormone homeostasis. In this review, we describe the common causes for pituitary deficiencies and the advances in cellular therapy to restore the physiological pituitary function.

Clinical Implications of ESR1 Mutations in Hormone Receptor-Positive Advanced Breast Cancer

PubMed Central

Reinert, Tomas; Saad, Everardo D.; Barrios, Carlos H.; Bines, José

2017-01-01

Hormone receptor-positive breast cancer is the most frequent breast cancer subtype. Endocrine therapy (ET) targeting the estrogen receptor (ER) pathway represents the main initial therapeutic approach. The major strategies include estrogen deprivation and the use of selective estrogen modulators or degraders, which show efficacy in the management of metastatic and early-stage disease. However, clinical resistance associated with progression of disease remains a significant therapeutic challenge. Mutations of the ESR1 gene, which encodes the ER, have been increasingly recognized as an important mechanism of ET resistance, with a prevalence that ranges from 11 to 39%. The majority of these mutations are located within the ligand-binding domain and result in an estrogen-independent constitutive activation of the ER and, therefore, resistance to estrogen deprivation therapy such as aromatase inhibition. ESR1 mutations, most often detected from liquid biopsies, have been consistently associated with a worse outcome and are being currently evaluated as a potential biomarker to guide therapeutic decisions. At the same time, targeted therapy directed to ESR1-mutated clones is an appealing concept with preclinical and clinical work in progress. PMID:28361033

Bone healing in 2016

Buza, John A.; Einhorn, Thomas

2016-01-01

Summary Delayed fracture healing and nonunion occurs in up to 5–10% of all fractures, and can present a challenging clinical scenario for the treating physician. Methods for the enhancement of skeletal repair may benefit patients that are at risk of, or have experienced, delayed healing or nonunion. These methods can be categorized into either physical stimulation therapies or biological therapies. Physical stimulation therapies include electrical stimulation, low-intensity pulsed ultrasonography, or extracorporeal shock wave therapy. Biological therapies can be further classified into local or systemic therapy based on the method of delivery. Local methods include autologous bone marrow, autologous bone graft, fibroblast growth factor-2, platelet-rich plasma, platelet-derived growth factor, and bone morphogenetic proteins. Systemic therapies include parathyroid hormone and bisphosphonates. This article reviews the current applications and supporting evidence for the use of these therapies in the enhancement of fracture healing. PMID:27920804

We examined the associations of mammographic breast density with breast cancer risk by tumor aggressiveness and by menopausal status and current postmenopausal hormone therapy. This study included 2596 invasive breast cancer cases and 4059 controls selected from participants of four nested case-control studies within four established cohorts: the Mayo Mammography Health Study, the Nurses' Health Study, Nurses' Health Study II, and San Francisco Mammography Registry. Percent breast density (PD), absolute dense (DA), and non-dense areas (NDA) were assessed from digitized film-screen mammograms using a computer-assisted threshold technique and standardized across studies. We used polytomous logistic regression to quantify the associations of breast density with breast cancer risk by tumor aggressiveness (defined as presence of at least two of the following tumor characteristics: size ≥2 cm, grade 2/3, ER-negative status, or positive nodes), stratified by menopausal status and current hormone therapy. Overall, the positive association of PD and borderline inverse association of NDA with breast cancer risk was stronger in aggressive vs. non-aggressive tumors (≥51 vs. 11-25% OR 2.50, 95% CI 1.94-3.22 vs. OR 2.03, 95% CI 1.70-2.43, p-heterogeneity = 0.03; NDA 4th vs. 2nd quartile OR 0.54, 95% CI 0.41-0.70 vs. OR 0.71, 95% CI 0.59-0.85, p-heterogeneity = 0.07). However, there were no differences in the association of DA with breast cancer by aggressive status. In the stratified analysis, there was also evidence of a stronger association of PD and NDA with aggressive tumors among postmenopausal women and, in particular, current estrogen+progesterone users (≥51 vs. 11-25% OR 3.24, 95% CI 1.75-6.00 vs. OR 1.93, 95% CI 1.25-2.98, p-heterogeneity = 0.01; NDA 4th vs. 2nd quartile OR 0.43, 95% CI 0.21-0.85 vs. OR 0.56, 95% CI 0.35-0.89, p-heterogeneity = 0.01), even though the interaction was not significant. Our findings suggest that associations of mammographic density with breast cancer risk differ by tumor aggressiveness. While there was no strong evidence that these associations differed by menopausal status or hormone therapy, they did appear more prominent among current estrogen+progesterone users.

The relationship between menopausal hormone therapy (MHT) and cardiovascular risk remains controversial, with a number of studies advocating the use of MHT in reducing risk of cardiovascular diseases, while others have shown it to increase risk. The aim of this study was to determine the association between menopausal hormone therapy and high blood pressure. A total of 43,405 postmenopausal women were included in the study. Baseline data for these women were sourced from the 45 and Up Study, Australia, a large scale study of healthy ageing. These women reported being postmenopausal, having an intact uterus, and had not been diagnosed with high blood pressure prior to menopause. Odds ratios for the association between MHT use and having high blood pressure were estimated using logistic regression, stratified by age (<56 years, 56-61 years, 62-70 years and over 71 years) and adjusted for demographic and lifestyle factors. MHT use was associated with higher odds of having high blood pressure: past menopausal hormone therapy use: <56 years (adjusted odds ratio 1.59, 99% confidence interval 1.15 to 2.20); 56-61 years (1.58, 1.31 to 1.90); 62-70 years (1.26, 1.10 to 1.44). Increased duration of hormone use was associated with higher odds of having high blood pressure, with the effect of hormone therapy use diminishing with increasing age. Menopausal hormone therapy use is associated with significantly higher odds of having high blood pressure, and the odds increase with increased duration of use. High blood pressure should be conveyed as a health risk for people considering MHT use.

Effect of oxandrolone therapy on adult height in Turner syndrome patients treated with growth hormone: a meta-analysis.

Turner syndrome is a chromosomal abnormality in which there is complete or partial absence of the X chromosome. Turner syndrome effects 1 in every 2000 live births. Short stature is a cardinal feature of Turner Syndrome and the standard treatment is recombinant human growth hormone. When growth hormone is started at an early age a normal adult height can be achieved. With delayed diagnosis young women with Turner Syndrome may not reach a normal height. Adjuvant therapy with oxandrolone is used but there is no consensus on the optimal timing of treatment, the duration of treatment and the long term adverse effects of treatment. The objective of this review and meta-analysis is to examine the effect of oxandrolone on adult height in growth hormone treated Turner syndrome patients. Eligible trials were identified by a literature search using the terms: Turner syndrome, oxandrolone. The search was limited to English language randomized-controlled trials after 1980. Twenty-six articles were reviewed and four were included in the meta-analysis. A random effects model was used to calculate an effect size and confidence interval. The pooled effect size of 2.0759 (95 % CI 0.0988 to 4.0529) indicates that oxandrolone has a positive effect on adult height in Turner syndrome when combined with growth hormone therapy. In conclusion, the addition of oxandrolone to growth hormone therapy for treatment of short stature in Turner syndrome improves adult height. Further studies are warranted to investigate if there is a subset of Turner syndrome patients that would benefit most from growth hormone plus oxandrolone therapy, and to determine the optimal timing and duration of such therapy.

Seasonal affective disorder (SAD), characterized by fall/winter major depression with spring/summer remission, is a prevalent mental health problem. SAD etiology is not certain, but available models focus on neurotransmitters, hormones, circadian rhythm dysregulation, genetic polymorphisms, and psychological factors. Light therapy is established as the best available treatment for SAD. Alternative and/or supplementary approaches involving medications, cognitive-behavioral therapy, and exercise are currently being developed and evaluated. Given the complexity of the disorder, interdisciplinary research stands to make a significant contribution to advancing our understanding of SAD conceptualization and treatment. PMID:21179639

Breast cancer remains a worldwide public health dilemma and is currently the most common tumour in the globe. Awareness of breast cancer, public attentiveness, and advancement in breast imaging has made a positive impact on recognition and screening of breast cancer. Breast cancer is life-threatening disease in females and the leading cause of mortality among women population. For the previous two decades, studies related to the breast cancer has guided to astonishing advancement in our understanding of the breast cancer, resulting in further proficient treatments. Amongst all the malignant diseases, breast cancer is considered as one of the leading cause of death in post menopausal women accounting for 23% of all cancer deaths. It is a global issue now, but still it is diagnosed in their advanced stages due to the negligence of women regarding the self inspection and clinical examination of the breast. This review addresses anatomy of the breast, risk factors, epidemiology of breast cancer, pathogenesis of breast cancer, stages of breast cancer, diagnostic investigations and treatment including chemotherapy, surgery, targeted therapies, hormone replacement therapy, radiation therapy, complementary therapies, gene therapy and stem-cell therapy etc for breast cancer.

Letrozole: a review of its use in the treatment of postmenopausal women with hormone-responsive early breast cancer.

PubMed

Keating, Gillian M

2009-08-20

Letrozole (Femara) is a third-generation, nonsteroidal aromatase inhibitor. Adjuvant therapy with letrozole is more effective than tamoxifen in postmenopausal women with hormone-responsive early breast cancer, and extended adjuvant therapy with letrozole after the completion of adjuvant tamoxifen therapy is more effective than placebo in this patient population; letrozole is generally well tolerated. Ongoing trials will help answer outstanding questions regarding the optimal duration of letrozole therapy in early breast cancer and its efficacy compared with other third-generation aromatase inhibitors such as anastrozole. In the meantime, letrozole should be considered a valuable option in the treatment of postmenopausal women with hormone-responsive early breast cancer, both as adjuvant and extended adjuvant therapy.

Gonadotropin-releasing hormone (GnRH) agonists (e.g., triptorelin) are used for androgen suppression therapy. They possess improved stability as compared to the natural GnRH, yet they suffer from a poor pharmacokinetic profile. To address this, we used a GnRH peptide-modified dendrimer platform with and without lipidation strategy. Dendrimers were synthesized on a polylysine core and bore either native GnRH (1, 2, and 5) or lipid-modified GnRH (3 and 4). Compound 3, which bore a lipidic moiety in a branched tetramer structure, showed approximately 10-fold higher permeability and metabolic stability and 39 times higher antitumor activity against hormone-resistant prostate cancer cells (DU145) relative to triptorelin. In gonadotropin-release experiments, dendrimer 3 was shown to be the most potent construct. Dendrimer 3 showed similar luteinizing hormone (LH)-release activity to triptorelin in mice. Our findings indicate that dendrimer 3 is a promising analog with higher potency for the treatment of hormone-resistant prostate cancer than the currently available GnRH agonists.

New therapies for two common prostate diseases, prostate cancer (PrCa) and benign prostatic hyperplasia (BPH), depend critically on experiments evaluating their hormonal regulation. Sex steroid hormones (notably androgens and estrogens) are important in PrCa and BPH; we probe their respective roles in inducing prostate growth and carcinogenesis in mice with experiments using compressed hormone pellets. Hormone and/or drug pellets are easily manufactured with a pellet press, and surgically implanted into the subcutaneous tissue of the male mouse host. We also describe a protocol for the evaluation of hormonal carcinogenesis by combining subcutaneous hormone pellet implantation with xenografting of prostate cell recombinants under the renal capsule of immunocompromised mice. Moreover, subcutaneous hormone pellet implantation, in combination with renal capsule xenografting of BPH tissue, is useful to better understand hormonal regulation of benign prostate growth, and to test new therapies targeting sex steroid hormone pathways.

• To evaluate tumour-associated macrophage (TAM) infiltration in prostate biopsy specimens as a possible prognostic factor for prostate cancer (PCa) after hormonal therapy. • Immunostaining of TAMs in prostate biopsy specimens was performed using a monoclonal antibody CD68 for 71 patients having PCa treated with hormonal therapy. • Six microscopic (×400) fields around the cancer foci were selected for TAM counting. • The median value of serum prostate-specific antigen (PSA) was 50.1 ng/mL, and the median TAM count was 22. • Recurrence-free survival was significantly better in patients with fewer TAMs (<22) than in those with higher numbers of TAMs (≥22) (P < 0.001). • TAM count was higher in those with higher serum PSA (PSA), higher Gleason score, clinical T stage or those with PSA failure. Cox multivariate analysis showed that TAM count is one of the prognostic factors for PCa treated by hormonal therapy (P < 0.0001). • TAM infiltration in prostate needle biopsy specimens is a useful predictive factor for PSA failure or progression of PCa after hormonal therapy. © 2010 THE AUTHORS.

The incidence of hot flashes under hormone manipulation therapy is so high that this symptom caused by sex hormone blocking agents has been bothering patients and has a negative impact on their quality of life. Venlafaxine and gabapentin are most promising novel nonestrogenic agents to control the symptom. We seek to quatitatively summarize the efficacy of these novel agents. We conducted a meta-analysis of randomized controlled studies on the efficacy of venlafaxine/gabapentin to hot flashes in cancer patient under hormone deprivation therapies. A search for Medline, Embase, Cochrane Central Register of Controlled Trials, Ichushi, and Google Scholar yielded 733 citations, which were independently assessed by two authors. We estimated overall effect sizes and its 95 % confidence intervals (CI) for the efficacy of these agents compared with the controls with standardized mean difference. A total of 5 studies involving 588 cancer patients with hot flashes finally fulfilled the predefined inclusion criteria. Overall effect size of the efficacy of venlafaxine/gabapentin was -0.630 (95 % CI [-0.801, -0.459]). Venlafaxine/gabapentin significantly improved hot flashes in cancer patients under hormone manipulation therapies.

Acromegaly is a hormonal disorder resulting from excessive growth hormone (GH) secretion frequently produced by pituitary adenomas and consequent increase in insulin-like growth factor 1 (IGF-I). Elevated GH and IGF-I levels result in a wide range of somatic, cardiovascular, endocrine, metabolic and gastrointestinal morbidities. Somatostatin analogues (SSAs) form the basis of medical therapy for acromegaly and are currently used as first-line treatment or as second-line therapy in patients undergoing unsuccessful surgery. However, a considerable percentage of patients do not respond to SSAs treatment. Somatostatin receptors (SSTR1-5) and dopamine receptors (DRD1-5) subtypes play critical roles in the regulation of hormone secretion. These receptors are considered important pharmacological targets to inhibit hormone oversecretion. It has been proposed that decreased expression of SSTRs may be associated with poor response to SSAs. Here, we systematically examine SSTRs and DRDs expression in human somatotroph adenomas by quantitative PCR. We observed an association between the response to SSAs treatment and DRD4, DRD5, SSTR1 and SSTR2 expression. We also examined SSTR expression by immunohistochemistry and found that the immunohistochemical detection of SSTR2 in particular might be a good predictor of response to SSAs. © 2017 The Authors.

2018-06-01

Hot flushes during menopause are distressing for women and result in poor quality of life. Purpose of the current review was to evaluate the available treatment modalities that should be utilised for the management of hot flushes. Menopause refers to last menses of women life and can be declared after amenorrhea of 12 months. Vasomotor symptoms including hot flushes and night sweats are common after menopause, affecting almost 50 - 85% women older than 45 years. The mean increment in core body and skin temperature is 0.5°C and 0.25 - 3°C during a hot flush attack. Low level of estrogen during menopause and its association in triggering episodes of hot flushes, is still under debate. The most accepted hypothesis is a narrowing of the thermoneutral zone (TNZ) triggered by estrogen fluctuations. Although, hormone replacement therapy (HRT) remains the standard treatment for the alleviation of such symptoms, incidence of life threatening side effects restrained medical professionals from its use. Complications associated with the use of HRT can be avoided by appropriate evaluation of patients before initiating therapy. Several guidelines have also recommended HRT (estrogen and progesterone) to be safe for up to a period of seven years. Both hormonal and non-hormonal treatments are used for the management of hot flushes. Since hot flushes are the least appreciated and neglected complication of menopause, current review provides detailed information on its background, pathophysiology and management, and emphasises the need of its treatment.

Growth hormone treatment and risk of recurrence or progression of brain tumors in children: a review.

PubMed

Bogarin, Roberto; Steinbok, Paul

2009-03-01

Brain tumors are one of the most common types of solid neoplasm in children. As life expectancy of these patients has increased with new and improved therapies, the morbidities associated with the treatments and the tumor itself have become more important. One of the most common morbidities is growth hormone deficiency, and since recombinant growth hormone (GH) became available, its use has increased exponentially. There is concern that in the population of children with brain tumors, GH treatment might increase the risk of tumor recurrence or progression or the appearance of a second neoplasm. In the light of this ongoing concern, the current literature has been reviewed to provide an update on the risk of tumor recurrence, tumor progression, or new intracranial tumor formation when GH is used to treat GH deficiency in children, who have had or have intracranial tumors. On the basis of this review, the authors conclude that the use of GH in patients with brain tumor is safe. GH therapy is not associated with an increased risk of central nervous system tumor progression or recurrence, leukemia (de novo or relapse), or extracranial non-leukemic neoplasms.

Atrial natriuretic peptide: a magic bullet for cancer therapy targeting Wnt signaling and cellular pH regulators.

PubMed

Serafino, A; Pierimarchi, P

2014-01-01

Atrial natriuretic peptide (ANP) is a cardiac hormone playing a crucial role in cardiovascular homeostasis mainly through blood volume and pressure regulation. In the last years, the new property ascribed to ANP of inhibiting tumor growth both in vitro and in vivo has made this peptide an attractive candidate for anticancer therapy. The molecular mechanism underlying the anti-proliferative effect of ANP has been mainly related to its interaction with the specific receptors NPRs, through which this natriuretic hormone inhibits some metabolic targets critical for cancer development, including the Ras-MEK1⁄2-ERK1⁄2 kinase cascade, functioning as a multikinase inhibitor. In this review we summarize the current knowledge on this topic, focusing on our recent data demonstrating that the antitumor activity of this natriuretic hormone is also mediated by a concomitant effect on the Wnt/β-catenin pathway and on the pH regulation ability of cancer cells, through a Frizzled-related mechanism. This peculiarity of simultaneously targeting two processes crucial for neoplastic transformation and solid tumor survival reinforces the utility of ANP for the development of both preventive and therapeutic strategies.

Little is known about the health-related quality of life of young adults with childhood onset idiopathic growth hormone deficiency or neurosecretory dysfunction of growth hormone secretion, who have been treated with recombinant human growth hormone (GH). Patients were diagnosed and treated with human growth hormone at the University Children´s Hospital in Erlangen (n=85). The data of both groups were merged for analysis, because no difference between idiopathic growth hormone deficiency and neurosecretory dysfunction of growth hormone secretion in auxological. Data were found. Health-related quality of life was cross- sectionally assessed after the end of growth hormone therapy with the Short Form-36 Health Survey and the Nottingham Health Profiles for which population based norm data are available. At the time of the survey, the patients (53 m, 32 f) were 23.5 ± 4.6 years old. At start of GH therapy, age was 10.5 ± 2.8 and at the end 16.3 ± 1,4 years. At start, height SDS was -3.20 ± 1.06. GH dose was 0,026 ± 0,012 mg/kg/d (daily s. c.-injections). The increase in height SDS after the end of GH therapy was 1.69 ± 1.22.  Compared to the reference population, patients reported significantly lower scores on the scales energy level, vitality, social functioning, indicating a greater social isolation, a stronger emotional reaction, an increased loss of mobility and a worse psychological state. Young adults report specific impairments after completion of GH therapy. © Georg Thieme Verlag KG Stuttgart · New York.

Hormone Therapy in Breast Cancer Survivors and Those at High Risk for Breast Cancer.

Women and health care providers are often fearful of using hormone therapy to deal with distressing menopausal symptoms in circumstances where there is a perceived or real increased risk of breast cancer. This paper examines the evidence for and against hormone therapy use in 3 common clinical situations: the woman with a positive family history in a first-degree relative, the woman who has undergone risk-reducing salpingo-oophorectomy due to a known genetic mutation, and the woman in whom treatment of breast cancer has induced premature menopause.

Transgender populations and HIV: unique risks, challenges and opportunities.

2016-04-01

Due to unique social, behavioural, structural and biological issues, transgender (TG) populations, especially TG women, are at high risk for HIV acquisition. This increased risk is multifactorial, due to differing psychosocial risk factors, poorer access to TG-specific healthcare, a higher likelihood of using exogenous hormones or fillers without direct medical supervision, interactions between hormonal therapy and antiretroviral therapy, and direct effects of hormonal therapy on HIV acquisition and immune control. Further research is needed to elucidate these mechanisms of risk and to help design interventions to reduce HIV risk among transgender populations.

The aim of the study was to describe the trajectories of depressive symptoms in a large population-based cohort of midaged women, and to examine the associations of current and changing reproductive stage with depressive symptoms over time. Prospective, population-based cohort study of 13,715 women aged 45 to 50 years followed up for over 15 years (Australian Longitudinal Study on Women's Health). Nearly 6,000 women provided complete data for this study. Menopause status was determined from questionnaires about hysterectomy, oophorectomy, hormone therapy, and menstrual patterns. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression scale (CESD-10). Latent class analysis indicated four distinct profiles of CESD-10 scores over 15 years: stable low (80.0%), increasing (9.0%), decreasing (8.5%), and stable high (2.5%). Those with "increasing" depressive symptoms were more likely to have had bilateral salpingo-oophorectomy or be perimenopausal at baseline compared with women in the "stable low" group. Depressive symptoms were higher in perimenopausal women, (higher CESD-10 score of 0.19, 95% CI 0.02, 0.31), after hysterectomy alone (0.53, 95% CI 0.31, 0.74), bilateral salpingo-oophorectomy with/without hysterectomy (0.85, 95% CI 0.58, 1.12), hormone therapy users (0.19, 95% CI 0.01, 0.36), and after starting or stopping hormone therapy compared with postmenopausal women (adjusted for sociodemographic factors, vasomotor symptoms, health behaviors, and history of depression diagnosis or treatment). Depressive symptoms follow distinct trajectories across the menopause transition. Most women have stable symptoms, but around 9% have increasing symptoms and a similar proportion (8.5%) decreasing symptoms. Increasing depressive symptoms were independent of vasomotor symptoms but were associated with oophorectomy and stopping or starting hormone therapy. A large number of women were excluded due to missing data, and thus the results should be interpreted with caution.

Serum testosterone measurement is recommended to assess the efficacy of androgen deprivation therapy (ADT) and to diagnose castration resistance in patients with prostate cancer (PCa). Currently, the accepted castrate level of serum testosterone is 50 ng/dL. Liquid chromatography and tandem mass spectrometry (LC MSMS) is the appropriate method to measure testosterone, especially at low levels. However, worldwide, chemiluminescent assays (CLIAs) are used in clinical laboratories, despite their lack of accuracy and reproducibility, because they are automatable, fast, sensitive, and inexpensive. We compared serum testosterone levels measured using LC MSMS and CLIAs in 126 patients with PCa undergoing luteinizing hormone-releasing hormone (LHRH) agonist therapy. The median serum testosterone level was 14.0 ng/dL (range, 2.0-67.0 ng/dL) with LC MSMS and 31.9 ng/dL (range, 10.0-91.6 ng/dL) with CLIA (P < .001). The serum testosterone levels, measured using LC MSMS, were < 20 ng/dL in 83 patients (65.9%), 20 to 50 ng/dL in 40 (31.7%), and > 50 ng/dL in 3 patients (2.4%). These ranges were found in 34 (27%), 72 (57.1%), and 20 (15.9%) patients when testosterone was measured using CLIA (P < .001). The castrate level of serum testosterone using LC MSMS and CLIA was 39.8 ng/dL (95% confidence interval [CI], 37.1-43.4 ng/dL) and 66.5 ng/dL (95% CI, 62.3-71.2 ng/dL), respectively. We found that CLIA overestimated the testosterone levels in PCa patients undergoing LHRH agonist therapy. Thus, the castration level was incorrectly considered inadequate with CLIA in almost 15% of patients. The true castration level of serum testosterone using an appropriate method is < 50 ng/dL.

Turner syndrome occurs in phenotypic females with complete or partial absence of X chromosome. The leading symptom is short stature, while numerous but mild stigmata manifest in the craniofacial region. These patients are commonly treated with growth hormone to improve their final height. The aim of this study was to assess the influence of long-term growth hormone therapy on craniofacial morphology in Turner syndrome patients. In this cross-sectional study cephalometric analysis was performed on 13 lateral cephalograms of patients with 45,X karyotype and the average age of 17.3 years, who have received growth hormone for at least two years. The control group consisted of 13 Turner syndrome patients naive to growth hormone treatment, matched to study group by age and karyotype. Sixteen linear and angular measurements were obtained from standard lateral cephalograms. Standard deviation scores were calculated in order to evaluate influence of growth hormone therapy on craniofacial components. In Turner syndrome patients treated with growth hormone most of linear measurements were significantly larger compared to untreated patients. Growth hormone therapy mainly influenced posterior face height, mandibular ramus height, total mandibular length, anterior face height and maxillary length. While the increase in linear measurements was evident, angular measurements and facial height ratio did not show statistically significant difference. Acromegalic features were not found. Long-term growth hormone therapy has positive influence on craniofacial development in Turner syndrome patients, with the greatest impact on posterior facial height and mandibular ramus. However, it could not compensate X chromosome deficiency and normalize craniofacial features. Copyright © 2016 Elsevier Ltd. All rights reserved.

[The menopause and the skin (author's transl)].

PubMed

Aron-Brunetière, R

It is currently admitted that the skin and its appendages plays an important part in steroid metabolism, especially in genital androgens, estrogens and progestogens. This activity produces the cutaneous changes sometimes associated with the premenopause period : facial hyper-seborrhea, seborrhea of the scalp, loss of scalp hairs, increaed pilosity on the cheeks and upper lip, whether they occur spontaneously or after hormonal treatment. Following the menopause-onset a progressive decreases in hair growth, can be observed, especially in the axillary and pubic regions, with occasional diffuse alopecia, increase in degeneration of elastic tissue, and atrophy of the vaginal mucosa, in fact as some changes appearing in the skin show correlations with the hormonal changes, others appear to be more closely related to aging of the skin. Thus, hormonal therapy will not be able to treat efficiently all these disorders.

Clinical practice guidelines for the diagnosis and management of osteoporosis. Scientific Advisory Board, Osteoporosis Society of Canada.

PubMed Central

1996-01-01

OBJECTIVE: To recommend clinical practice guidelines for the assessment of people at risk for osteoporosis, and for effective diagnosis and management of the condition. OPTIONS: Screening and diagnostic methods: risk-factor assessment, clinical evaluation, measurement of bone mineral density, laboratory investigations. Prophylactic and corrective therapies: calcium and vitamin D nutritional supplementation, physical activity and fall-avoidance techniques, ovarian hormone therapy, bisphosphonate drugs, other drug therapies. Pain-management medications and techniques. OUTCOMES: Prevention of loss of bone mineral density and fracture; increased bone mass; and improved quality of life. EVIDENCE: Epidemiologic and clinical studies and reports were examined, with emphasis on recent randomized controlled trials. Clinical practice in Canada and elsewhere was surveyed. Availability of treatment products and diagnostic equipment in Canada was considered. VALUES: Cost-effective methods and products that can be adopted across Canada were considered. A high value was given to accurate assessment of fracture risk and osteoporosis, and to increasing bone mineral density, reducing fractures and fracture risk and minimizing side effects of diagnosis and treatment. BENEFITS, HARMS AND COSTS: Proper diagnosis and management of osteoporosis minimize injury and disability, improve quality of life for patients and reduce costs to society. Rationally targeted methods of screening and diagnosis are safe and cost effective. Harmful side effects and costs of recommended therapies are minimal compared with the harms and costs of untreated osteoporosis. Alternative therapies provide a range of choices for physicians and patients. RECOMMENDATIONS: Population sets at high risk should be identified and then the diagnosis confirmed through bone densitometry. Dual-energy x-ray absorptiometry is the preferred measurement technique. Radiography can be adjunct when indicated. Calcium and vitamin D nutritional supplementation should be at currently recommended levels. Patients should be counselled in fall-avoidance techniques and exercises. Immobilization should be avoided. Guidelines for management of acute pain are listed. Ovarian hormone therapy is the therapy of choice for osteoporosis prevention and treatment in postmenopausal women. Bisphosphonates are an alternative therapy for women with established osteoporosis who cannot or prefer not to take ovarian hormone therapy. PMID:8873639

The aim of the present study was to evaluate the alterations that may take place in the bacterial genital tract flora in the absence of ovarian hormones. The role of hormone replacement therapy was also assessed. For this purpose, various bacteria were identified from the vaginal flora of ovariectomized and sham operated female rats, following the Bergey's manual criteria. The data of this study showed that substantial differences exist in the vaginal bacterial microflora between ovariectomized and normal cyclic rats. Ovariectomy was associated with a lower total bacterial load that may be due mainly to the absence of Lactobacillus. Anaerobic bacteria were also absent. Streptococcus and Enterococcus were also not favored in an environment lacking the ovarian hormones. In contrast, C. perfringens, Bacteroides, S. epidermidis, and S. aureus were detected in high numbers in ovariectomized rats. In terms of the impact of hormone replacement therapy on vaginal flora, only estradiol (EE2) restored Lactobacillus levels in ovariectomized rats, whereas all hormonal schemes used brought Streptococcus, Clostridium lec (-), and C. perfringens, the spore and vegetative forms, close to those detected in normal cyclic female rats. In conclusion, ovarian hormones appeared to be regulatory factors that favor the presence of a broad variety of bacteria, which are members of the normal genital tract flora. On the other hand, ovariectomy modifies the vaginal microbial profile, and hormone replacement therapy based mainly on schemes containing EE2 could alleviate this disturbance.

Do hormone treatments for prostate cancer cause anxiety and depression?

PubMed

Sharpley, Christopher F; Christie, David R H; Bitsika, Vicki

2014-01-01

To investigate the relationship between hormone therapy (HT) and incidence of anxiety and depression among prostate cancer patients (PCa). 526 PCa patients completed a survey about their cancer status, treatment received, anxiety, and depression status. Total scores on anxiety and depression inventories, plus symptom profiles that discriminated between patients with current HT, past HT, and never having received HT, were compiled for analysis. Patients who were currently receiving HT had significantly higher total anxiety and depression scores than patients who had previously received HT or who had never received HT. Analysis of the symptoms of anxiety and depression which distinguished between these groups of patients suggested that patients who had never received HT had significantly lower scores than current or past HT patients. Although several symptoms could be directly allocated to PCa and/or HT, symptom profiles were indicative of clinically significant anxiety and/or depression in patients who were currently receiving, or who had previously received, HT. Current HT may lead to symptoms of anxiety and/or depression which require clinical attention. These effects seem to decrease after completion of HT.

To investigate the effects of cognitive function on discontinuation of hormonal therapy in breast cancer survivors ages 65+ ("older"). Older breast cancer survivors with invasive, non-metastatic disease, and no reported cognitive difficulties were recruited from 78 Alliance sites between 2004 and 2011. Eligible survivors (n = 1280) completed baseline interviews; follow-up was conducted annually for up to 7 years. Survivors with estrogen-receptor-positive (ER+) cancers who initiated hormonal therapy (n = 990) were included. Self-reported cognitive function was measured using the EORTC-QLQ30 scale; a difference of eight points on the 0-100 scale was considered clinically significant. Based on varying rates of discontinuation over time, discontinuation was evaluated separately for three time periods: early (<1 year); midpoint (1-3 years); and late discontinuation (>3-5 years). Cox models for each time period were used to evaluate the effects of cognition immediately preceding discontinuation, controlling for age, chemotherapy, and other covariates. Survivors were 65-91 years old (mean 72.6 years), and 79% had stages 1 or 2A disease. Overall, 43% discontinued hormonal therapy before 5 years. Survivors who reported lower cognitive function in the period before discontinuation had greater hazards of discontinuing therapy at the treatment midpoint (HR 1.22 per 8-point difference, CI 1.09-1.40, p < 0.001), considering covariates, but cognition was not related to discontinuation in the other periods. Self-reported cognitive problems were a significant risk factor for discontinuation of hormonal therapy 1-3 years post-initiation. Additional research is needed on the temporality of cognitive effects and hormonal therapy to support survivorship care needs of older survivors.

Mitchell, Darren M.; McAleese, Jonathan; Park, Richard M.

2007-12-01

Purpose: To investigate whether failure to suppress the prostate-specific antigen (PSA) level to {<=}1 ng/mL after {>=}2 months of neoadjuvant luteinizing hormone-releasing hormone agonist therapy in patients scheduled to undergo external beam radiotherapy for localized prostate carcinoma is associated with reduced biochemical failure-free survival. Methods and Materials: A retrospective case note review of consecutive patients with intermediate- or high-risk localized prostate cancer treated between January 2001 and December 2002 with neoadjuvant hormonal deprivation therapy, followed by concurrent hormonal therapy and radiotherapy was performed. Patient data were divided for analysis according to whether the PSA level in Week 1 of radiotherapymore » was {<=}1.0 ng/mL. Biochemical failure was determined using the American Society for Therapeutic Radiology and Oncology (Phoenix) definition. Results: A total of 119 patients were identified. The PSA level after neoadjuvant hormonal deprivation therapy was {<=}1 ng/mL in 67 patients and >1 ng/mL in 52. At a median follow-up of 49 months, the 4-year actuarial biochemical failure-free survival rate was 84% vs. 60% (p = 0.0016) in favor of the patients with a PSA level after neoadjuvant hormonal deprivation therapy of {<=}1 ng/mL. The overall survival rate was 94% vs. 77.5% (p = 0.0045), and the disease-specific survival rate at 4 years was 98.5% vs. 82.5%. Conclusions: The results of our study have shown that patients with a PSA level >1 ng/mL at the beginning of external beam radiotherapy after {>=}2 months of neoadjuvant luteinizing hormone-releasing hormone agonist therapy have a significantly greater rate of biochemical failure and lower survival rate compared with those with a PSA level of {<=}1 ng/mL. Patients without adequate PSA suppression should be considered a higher risk group and considered for dose escalation or the use of novel treatments.« less

Investigational drugs for the treatment of endometriosis, an update on recent developments.

2018-05-01

Endometriosis is a hormone-dependent benign chronic disease that requires a chronic medical therapy. Although currently available drugs are efficacious in treating endometriosis-related pain, some women experience partial or no improvement. Moreover, the recurrence of symptoms is expected after discontinuation of the therapies. Currently, new drugs are under intense clinical investigation for the treatment of endometriosis. Areas covered: This review aims to offer the reader a complete and updated overview on new investigational drugs and early molecular targets for the treatment of endometriosis. The authors describe the pre-clinical and clinical development of these agents. Expert opinion: Among the drugs under investigation, late clinical trials on gonadotropin-releasing hormone antagonists (GnRH-ant) showed the most promising results for the treatment of endometriosis. Aromatase inhibitors (AIs) are efficacious in treating endometriosis related pain symptoms but they cause significant adverse effects that limit their long-term use. New targets have been identified to produce drugs for the treatment of endometriosis, but the majority of these new compounds have only been investigated in laboratory studies or early clinical trials. Thus, further clinical research is required in order to elucidate their efficacy and safety in human.

Prepubertal Gynecomastia Due to Indirect Exposure to Nonformulary Bioidentical Hormonal Replacement Therapy: A Case Report.

Gynecomastia is a disorder of the endocrine system characterized by an abnormal presence of a palpable unilateral or bilateral enlargement and proliferation of glandular ductal benign breast tissue in male individuals. This case discusses the medical implications of an unregulated, indirect exposure to nonformulary, bioidentical hormone replacement therapy in male children. An 8-year-old boy presented with prepubertal gynecomastia secondary to estrogen exposure from maternal use of bioidentical hormonal replacement therapy (the Wiley protocol). We review the literature on prepubertal gynecomastia secondary to exogenous estrogen exposure, evaluation, clinical surveillance of the pubertal development, and relevant short- and long-term implications. Indirect exposure to nonformulary hormonal replacement in our case report was an etiologic factor in the development of prepubertal gynecomastia. This novel estrogen exposure source has important implications in the differential diagnosis of prepubertal gynecomastia and potential adverse effects secondary to precocious hormonal exposure.

Impact of growth hormone therapy on adult height of children with idiopathic short stature: systematic review.

To systematically determine the impact of growth hormone therapy on adult height of children with idiopathic short stature. Systematic review. Cochrane Central Register of Controlled Trials, Medline, and the bibliographic references from retrieved articles of randomised and non-randomised controlled trials from 1985 to April 2010. Height in adulthood (standard deviation score) and overall gain in height (SD score) from baseline measurement in childhood. Randomised and non-randomised controlled trials with height measurements for adults. Inclusion criteria were initial short stature (defined as height >2 SD score below the mean), peak growth hormone responses >10 μg/L, prepubertal stage, no previous growth hormone therapy, and no comorbid conditions that would impair growth. Adult height was considered achieved when growth rate was <1.5 cm/year or bone age was 15 years in females and 16 years in males. Three randomised controlled trials (115 children) met the inclusion criteria. The adult height of the growth hormone treated children exceeded that of the controls by 0.65 SD score (about 4 cm). The mean height gain in treated children was 1.2 SD score compared with 0.34 SD score in untreated children. A slight difference of about 1.2 cm in adult height was observed between the two growth hormone dose regimens. In the seven non-randomised controlled trials the adult height of the growth hormone treated group exceeded that of the controls by 0.45 SD score (about 3 cm). Growth hormone therapy in children with idiopathic short stature seems to be effective in partially reducing the deficit in height as adults, although the magnitude of effectiveness is on average less than that achieved in other conditions for which growth hormone is licensed. The individual response to therapy is highly variable, and additional studies are needed to identify the responders.

Women's experiences of hormonal therapy for breast cancer: exploring influences on medication-taking behaviour.

Five to 10 years of adjuvant hormonal therapy is recommended to prevent breast cancer recurrence. This study investigated modifiable influences on adjuvant hormonal therapy medication-taking behaviour (MTB) in women with stage I-III breast cancer. Semi-structured face-to-face interviews among women with stage I-III breast cancer prescribed adjuvant hormonal therapy purposively sampled by their MTB at two cancer centres. Thematic analysis was conducted based on the Framework approach, with the Theoretical Domains Framework (TDF) informing the analysis framework; the TDF is an integrative framework consisting of 14 domains of behavioural change to inform intervention design. Thirty-one women participated in interviews (14 adherent/persistent; 7 non-adherent/persistent; 10 non-persistent). Three domains identified both barriers and enablers to hormonal therapy MTB across the three MTB strata: beliefs about consequences, intentions and goals and behaviour regulation, but their influence was different across the strata. Other domains influenced individual MTB strata. Key enablers for adherent/persistent women were identified within the domain beliefs about consequences (breast cancer recurrence), intentions and goals (high-priority), beliefs about capabilities (side effects) and behaviour regulation (managing medication). Barriers were identified within the domain behaviour regulation (no routine), memory, attention and decision processes (forgetting) and environmental context and resources (stressors) for non-adherent/persistent women and intentions and goals (quality of life), behaviour regulation (temporal self-regulation), reinforcement, beliefs about consequences (non-necessity) and social influences (clinical support) for non-persistent women. This study identified modifiable influences on hormonal therapy MTB. Targeting these influences in clinical practice may improve MTB and hence survival in this population.

Broodstock management and hormonal manipulations of fish reproduction.

PubMed

Mylonas, Constantinos C; Fostier, Alexis; Zanuy, Silvia

2010-02-01

Control of reproductive function in captivity is essential for the sustainability of commercial aquaculture production, and in many fishes it can be achieved by manipulating photoperiod, water temperature or spawning substrate. The fish reproductive cycle is separated in the growth (gametogenesis) and maturation phase (oocyte maturation and spermiation), both controlled by the reproductive hormones of the brain, pituitary and gonad. Although the growth phase of reproductive development is concluded in captivity in most fishes-the major exemption being the freshwater eel (Anguilla spp.), oocyte maturation (OM) and ovulation in females, and spermiation in males may require exogenous hormonal therapies. In some fishes, these hormonal manipulations are used only as a management tool to enhance the efficiency of egg production and facilitate hatchery operations, but in others exogenous hormones are the only way to produce fertilized eggs reliably. Hormonal manipulations of reproductive function in cultured fishes have focused on the use of either exogenous luteinizing hormone (LH) preparations that act directly at the level of the gonad, or synthetic agonists of gonadotropin-releasing hormone (GnRHa) that act at the level of the pituitary to induce release of the endogenous LH stores, which, in turn act at the level of the gonad to induce steroidogenesis and the process of OM and spermiation. After hormonal induction of maturation, broodstock should spawn spontaneously in their rearing enclosures, however, the natural breeding behavior followed by spontaneous spawning may be lost in aquaculture conditions. Therefore, for many species it is also necessary to employ artificial gamete collection and fertilization. Finally, a common question in regards to hormonal therapies is their effect on gamete quality, compared to naturally maturing or spawning broodfish. The main factors that may have significant consequences on gamete quality-mainly on eggs-and should be considered when choosing a spawning induction procedure include (a) the developmental stage of the gonads at the time the hormonal therapy is applied, (b) the type of hormonal therapy, (c) the possible stress induced by the manipulation necessary for the hormone administration and (d) in the case of artificial insemination, the latency period between hormonal stimulation and stripping for in vitro fertilization.

Surgery for the primary breast tumour is usually not recommended in metastatic breast cancer (MBC); however, some reports have suggested a benefit of locoregional treatment. We designed this study to evaluate the efficacy of locoregional surgery in MBC. Data for patients diagnosed with MBC at Samsung Medical Center between 1995 and 2011 were retrospectively collected. We compared the survival benefit of all treatment modalities using Cox regression analysis. Subgroup analyses based on number of metastases were performed to delineate the indication for each treatment. Among 262 patients, 40 (15.3%) underwent surgery. Other treatments included chemotherapy (n = 213, 81.3%), radiotherapy (n = 138, 52.7%), hormone therapy (n = 118, 45.0%) and HER2/neu receptor (HER2)-targeted therapy (n = 37, 14.1%). Cox regression analysis showed that surgery (hazard ratios (HR) = 0.51, P < 0.01), hormone therapy (HR = 0.31, P < 0.01) and HER2-targeted therapy (HR = 0.33, P < 0.01) were associated with improved survival, whereas presence of three or more metastatic organs (HR = 1.62, P = 0.03) was associated with poor survival. In patients with metastasis to a single organ, surgery (HR = 0.43, P < 0.01), chemotherapy (HR = 0.62, P = 0.05), hormone therapy (HR = 0.39, P < 0.01) and HER2-targeted therapy (HR = 0.39, P = 0.02) had a survival benefit. Furthermore, for patients with bone-only metastasis, surgery (HR = 0.37, P = 0.02), chemotherapy (HR = 0.42, P < 0.01), hormone therapy (HR = 0.22, P < 0.01) and HER2-targeted therapy (HR = 0.09, P = 0.02) showed a survival benefit. However, only hormone therapy and HER2-targeted therapy had a survival benefit in MBC with metastasis to multiple organs. Surgical control of the primary breast tumour should be considered as a locoregional therapy in combination with systemic therapy in MBC with metastasis to a single organ, especially bone-only metastasis.

The relationships between bone turnover, the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis and vitamin D are complex, but still not fully explained. The GH/IGF-1 axis and vitamin D can mutually modulate each other's metabolism and influence the activation of cell proliferation, maturation, and mineralization as well as bone resorption. The aim of this study was to evaluate the reciprocal associations between bone formation markers [alkaline phosphatase (ALP), bone alkaline phosphatase (BALP)], the GH/IGF-1 axis and 25-hydroxyvitamin D [25(OH)D] in children with growth hormone deficiency at baseline and during recombinant human growth hormone (rhGH) therapy. ALP, BALP, 25(OH)D and IGF-1 levels were evaluated in 53 patients included in this prospective three-year study. ALP, BALP and IGF-1 increased during rhGH therapy. Baseline ALP activity correlated positively with baseline height velocity (HV). ALP and BALP activity at 12 months correlated positively with HV in the first year of therapy. We found positive correlations between ALP and IGF-1 at baseline and during the first year of therapy, between BALP activity at 12 months and rhGH dose in the first year of therapy, and between doses of cholecalciferol in the first year of rhGH therapy and early changes in BALP activity during rhGH therapy. Our results indicate that vitamin D supplementation enhances the effect of rhGH on bone formation process, which could improve the effects of rhGH therapy. ALP and BALP activity are useful in the early prediction of the effects of rhGH therapy, but their utility as long-term predictors seemed insufficient.

Oral contraceptive therapy for polycystic ovary disease after chronic gonadotropin-releasing agonist administration. Predictors of continued ovarian suppression.

1996-09-01

To study the beneficial effects of oral contraceptive (OC) therapy following gonadotropin-releasing hormone agonist (GnRH-a) administration in women with polycystic ovary disease (PCOD). Twenty-three hyperandrogenic women (aged 15-39) were randomized into two groups; GnRH-a (depot every 28 days) for six months or combination therapy (GnRH-a plus OC "addback") for six months. Following six months of treatment with either therapy, all patients received OC therapy for at least six months. The hormonal state was evaluated at three-month intervals. Hormone levels of luteinizing hormone (LH), testosterone (T) and free T remained suppressed within the normal range in 11 of 17 patients (65%) during the six months of OC only therapy, while the other six patients showed "escape" from suppression, with the LH, T and free T concentrations rising to pre-GnRH-a treatment levels. Use of OC addback therapy did not potentiate the long-acting therapeutic effect of GnRH-a pretreatment; three of six patients in the escape group were pretreated with combination therapy and three with GnRH-a only. In the majority of women with PCOD, OC therapy following GnRH-a administration was effective in maintaining ovarian androgen suppression. Failure to maintain ovarian suppression in this patient population was associated with higher elevations of baseline free T concentrations.

Acupuncture for menopausal vasomotor symptoms: study protocol for a randomised controlled trial

PubMed Central

2014-01-01

Background Hot flushes and night sweats (vasomotor symptoms) are common menopausal symptoms, often causing distress, sleep deprivation and reduced quality of life. Although hormone replacement therapy is an effective treatment, there are concerns about serious adverse events. Non-hormonal pharmacological therapies are less effective and can also cause adverse effects. Complementary therapies, including acupuncture, are commonly used for menopausal vasomotor symptoms. While the evidence for the effectiveness of acupuncture in treating vasomotor symptoms is inconclusive, acupuncture has a low risk of adverse effects, and two small studies suggest it may be more effective than non-insertive sham acupuncture. Our objective is to assess the efficacy of needle acupuncture in improving hot flush severity and frequency in menopausal women. Our current study design is informed by methods tested in a pilot study. Methods/design This is a stratified, parallel, randomised sham-controlled trial with equal allocation of participants to two trial groups. We are recruiting 360 menopausal women experiencing a minimum average of seven moderate hot flushes a day over a seven-day period and who meet diagnostic criteria for the Traditional Chinese Medicine diagnosis of Kidney Yin deficiency. Exclusion criteria include breast cancer, surgical menopause, and current hormone replacement therapy use. Eligible women are randomised to receive either true needle acupuncture or sham acupuncture with non-insertive (blunt) needles for ten treatments over eight weeks. Participants are blinded to treatment allocation. Interventions are provided by Chinese medicine acupuncturists who have received specific training on trial procedures. The primary outcome measure is hot flush score, assessed using the validated Hot Flush Diary. Secondary outcome measures include health-related quality of life, anxiety and depression symptoms, credibility of the sham treatment, expectancy and beliefs about acupuncture, and adverse events. Participants will be analysed in the groups in which they were randomised using an intention-to-treat analysis strategy. Discussion Results from this trial will significantly add to the current body of evidence on the role of acupuncture for vasomotor symptoms. If found to be effective and safe, acupuncture will be a valuable additional treatment option for women who experience menopausal vasomotor symptoms.

A summary of the influence of exogenous estrogen administration across the lifespan on the GH/IGF-1 axis and implications for bone health.

PubMed

Southmayd, Emily A; De Souza, Mary Jane

2017-02-01

Bone growth, development, and remodeling are modulated by numerous circulating hormones. Throughout the lifespan, the extent to which each of the hormones impacts bone differs. Understanding the independent and combined impact of these hormones on controlling bone remodeling allows for the development of more informed decision making regarding pharmacology, specifically the use of hormonal medication, at all ages. Endocrine control of bone health in women is largely dictated by the growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis and the hypothalamic-pituitary-ovarian (HPO) axis. Growth hormone, secreted from the pituitary gland, stimulates cells in almost every tissue to secrete IGF-1, although the majority of circulating IGF-1 is produced hepatically. Indeed, systemic IGF-1 concentrations have been found to be correlated with bone mineral density (BMD) in both pre- and post-menopausal women and is often used as a marker of bone formation. Sex steroids produced by the ovaries, namely estradiol, mediate bone resorption through binding to estrogen receptors on osteoclasts and osteoblasts. Specifically, by increasing osteoclast apoptosis and decreasing osteoblast apoptosis, adequate estrogen levels prevent excessive bone resorption, which helps to explain the rapid decline in bone mass that occurs with the menopausal decrease in estrogen production. Though there are documented correlations between endogenous estrogen concentrations and GH/IGF-1 dynamics, this relationship changes across the lifespan as sex-steroid dynamics fluctuate and, possibly, as tissue responsiveness to GH stimulation decreases. Aside from the known role of endogenous sex steroids on bone health, the impact of exogenous estrogen administration is of interest, as exogenous formulations further modulate GH and IGF-1 production. However, the effect and extent of GH and IGF-1 modulation seems to be largely dependent on age at administration and route of administration. Specifically, premenopausal women using combined oral contraceptive therapy (COC), post-menopausal women taking oral hormone therapy (HT), and both pre- and post-menopausal women using a transdermal form of estrogen therapy (COC or HT) demonstrate disparate GH/IGF-1 responses to exogenous estrogen. This review serves to summarize what is currently known regarding the influence of exogenous estrogen administration across the lifespan on the GH/IGF-1 axis and implications for bone health.

Cognitive Deficits in Breast Cancer Survivors After Chemotherapy and Hormonal Therapy.

PubMed

Frank, Jennifer Sandson; Vance, David E; Triebel, Kristen L; Meneses, Karen M

2015-12-01

Adjuvant treatments, specifically chemotherapy and hormonal therapy, have dramatically increased breast cancer survival, resulting in increased attention to the residual effects of treatment. Breast cancer survivors (BCS) frequently report that cognitive deficits are a particular source of distress, interfering with many aspects of quality of life. The literature on neuropsychological performance measures in BCS supports the reality of subtle cognitive deficits after both chemotherapy and hormonal therapy. This premise is supported by recent imaging studies, which reveal anatomical changes after chemotherapy as well as changes in patterns of neural activation while performing cognitive tasks. This review suggests that, even when performance on neuropsychological performance measures is within normal limits, BCS may be using increased cognitive resources in the face of reduced cognitive reserve. Potential interventions for cognitive deficits after adjuvant therapy include prescriptions for healthy living, pharmacotherapy, complementary therapy, and cognitive remediation therapy directed toward specific cognitive deficits or a combination of several strategies.

Taylor, Maida

2015-09-01

Given the persistent confusion about the risks and benefits of hormone therapy since 2002 and the first publication from the Women's Health Initiative's primary findings, women and health care providers are increasingly motivated to find effective, nonhormonal approaches to treat menopause-related symptoms. Complementary and alternative medicine has grown increasingly popular in the last decade. A wide array of botanic medicines is offered as an alternative approach to hormone therapy for menopause, but data documenting efficacy and safety are limited. None of the available botanicals is as effective as hormone therapy in the management of vasomotor symptoms. Copyright © 2015 Elsevier Inc. All rights reserved.

[Climacteric--medicalization, minimalization or normalization?].

PubMed

Hovelius, B; Ekström, H; Esseveld, J; Landgren, B M; Vinge, E

2000-12-13

Women's experiences and ideas about the climacteric are not in accord with the biomedical model, in which the climacteric and the menopause are characterized as being a risk factor for various diseases and a cause of "estrogen deficiency", a hormonal disease which is assumed to persist during the rest of life. The biomedical model may lead to medicalization and pathologizing, increasing the subordination of women and making them dependent on the health care system. Women who use hormonal therapy during the climacteric have many characteristics differentiating them from women who do not use such therapy. Thus, epidemiological studies will be difficult to interpret with respect to the long term effects of hormonal therapy. It is argued that the consultation for women of middle-age should be characterized by a holistic view of the woman taking account of her gender identity, life conditions and life situation. Such a view should focus on the woman's own ideas as to diagnostic procedures, treatment and solutions. In view of the lack of knowledge about the pros and cons of hormonal therapy, women themselves should make the decision, and such decisions should be encouraged. Also, the efforts directed towards women's compliance to hormonal therapy can be questioned. Women's climacteric symptoms should neither be medicalized, pathologized or minimized.

Severe angioedema in myxedema coma: a difficult airway in a rare endocrine emergency.

PubMed

Lee, Christopher H; Wira, Charles R

2009-10-01

Myxedema coma is the most lethal manifestation of hypothyroidism. It is a true medical emergency and can result in profound hemodynamic instability and airway compromise. Myxedema coma currently remains a diagnostic challenge due to the rarity of cases seen today, and failure to promptly initiate therapy with replacement thyroid hormone can be fatal. As thyroid hormone therapy can take days or weeks to reverse the manifestations of myxedema coma, interim supportive therapy is critical while awaiting clinical improvement. Some patients will require endotracheal intubation in the emergency department (ED), and physicians should be aware that unanticipated posterior pharyngeal edema in myxedema coma could severely complicate airway management. Although mechanical ventilation is a well-described adjunctive therapy for myxedema coma, reports of the potential difficulty in securing a definitive airway in these patients are rare. We describe a case of an unidentified woman who presented to the ED with myxedema coma requiring urgent endotracheal intubation and was found to have extensive posterior pharyngeal angioedema inconsistent with her relatively benign external examination. This case highlights the typical features of myxedema coma and discusses our necessity for a rescue device in definitive endotracheal tube placement. Emergency physicians should anticipate a potentially difficult airway in all myxedema coma patients regardless of the degree of external facial edema present.

To investigate the effect of growth hormone on proliferative activity of the residual small intestinal mucosa after massive small intestinal resection and to evaluate the clinical efficacy of bowel rehabilitative therapy for short bowel syndrome. Small intestinal mucosa proliferative activity were compared in rats from control group (sham operation), short bowel group (80% small bowel resection) and growth hormone treatment group (80% small bowel resection + growth hormone 1 U x kg(-1) x d(-1) for 28 days) with the aid of histology image analysis, flow cytometric assay, immunohistochemistry analysis and RT-PCR assay. The nutritional status, D-xylose absorption and stool nitrogen output were observed in 9 consecutive parenteral nutrition dependent patients with short bowel syndrome after intestinal rehabilitative therapy (growth hormone 8 - 12 U x kg(-1) x d(-1) im + glutamine 0.6 g x kg(-1) x d(-1) iv + special diet) for 21 continuous days. Growth hormone administration significantly increased rat small intestinal mucosal villous height, mucosal thickness, proliferative index, and the expression of proliferating cell nuclear antigen and c-jun mRNA. Rehabilitative therapy increased the body weight, serum total protein and album in concentrations in patients. Their D-xylose absorption indices increased and fecal nitrogen losses decreased. Follow-up data showed that 6 of the 9 patients sustained on enteral nutrition. Growth hormone enhances the proliferative activity of the mucosal epithelium and bowel rehabilitative therapy may benefit the patients with short bowel syndrome.

Menstrual migraine: a review of current and developing pharmacotherapies for women.

2018-02-01

Migraine is one of the most common neurological disorders in the general population. It affects 18% of women and 6% of men. In more than 50% of women migraineurs the occurrence of migraine attacks correlates strongly with the perimenstrual period. Menstrual migraine is highly debilitating, less responsive to therapy, and attacks are longer than those not correlated with menses. Menstrual migraine requires accurate evaluation and targeted therapy, that we aim to recommend in this review. Areas covered: This review of the literature provides an overview of currently available pharmacological therapies (especially with triptans, anti-inflammatory drugs, hormonal strategies) and drugs in development (in particular those acting on calcitonin gene-related peptide) for the treatment of acute migraine attacks and the prophylaxis of menstrual migraine. The studies reviewed here were retrieved from the Medline database as of June 2017. Expert opinion: The treatment of menstrual migraine is highly complex. Accurate evaluation of its characteristics is prerequisite to selecting appropriate therapy. An integrated approach involving neurologists and gynecologists is essential for patient management and for continuous updating on new therapies under development.

To assess whether the dual-hormone (insulin and glucagon) artificial pancreas reduces hypoglycaemia compared to the single-hormone (insulin alone) artificial pancreas in outpatient settings during the day and night. In a randomized, three-way, crossover trial we compared the dual-hormone artificial pancreas, the single-hormone artificial pancreas and sensor-augmented pump therapy (control) in 23 adults with type 1 diabetes. Each intervention was applied from 8 AM Day 1 to 8 PM Day 3 (60 hours) in outpatient free-living conditions. The primary outcome was time spent with sensor glucose levels below 4.0 mmol/L. A P value of less than .017 was regarded as significant. The median difference between the dual-hormone system and the single-hormone system was -2.3% (P = .072) for time spent below 4.0 mmol/L, -1.3% (P = .017) for time below 3.5 mmol/L, and -0.7% (P = .031) for time below 3.3 mmol/L. Both systems reduced (P < .017) hypoglycaemia below 4.0, 3.5 and 3.3 mmol/L compared to control therapy, but reductions were larger with the dual-hormone system than with the single-hormone system (medians -4.0% vs -3.4% for 4.0 mmol/L; -2.7% vs -2.2% for 3.5 mmol/L; and -2.2% vs -1.2% for 3.3 mmol/L). There were 34 hypoglycaemic events (<3.0 mmol/L for 20 minutes) with control therapy, 14 with the single-hormone system and 6 with the dual-hormone system. These differences in hypoglycaemia were observed while mean glucose level was low and comparable in all interventions (P = NS). The dual-hormone artificial pancreas had the lowest risk of hypoglycaemia, but the differences were not statistically significant. Larger studies are needed. © 2017 John Wiley & Sons Ltd.

Optimizing Quality of Life in Patients with Hormone Receptor-Positive Metastatic Breast Cancer: Treatment Options and Considerations.

PubMed

2017-01-01

The treatment landscape for hormone receptor-positive metastatic breast cancer continues to evolve as the molecular mechanisms of this heterogeneous disease are better understood and targeted treatment strategies are developed. Patients are now living for extended periods of time with this disease as they progress through sequential lines of treatment. With a rapidly expanding therapeutic armamentarium, the prevalence of metastatic breast cancer patients with prolonged survival is expected to increase, as is the duration of survival. Practice guidelines recommend endocrine therapy alone as first-line therapy for the majority of patients with metastatic hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. The approval of new agents and expanded combination options has extended their use beyond first line, but endocrine therapy is not used as widely in clinical practice as recommended. As all treatments are palliative, even as survival is prolonged, optimizing and maintaining patient quality of life is crucial. This article surveys data relevant to the use of endocrine therapy in the setting of hormone receptor-positive metastatic breast cancer, including key clinical evidence regarding approved therapies and the impact of these therapies on patient quality of life. © 2017 S.

Animal models of menopause have been used to further define the cognitive processes that respond to hormone therapy and to investigate parameters that may influence the cognitive effects of estrogen. Many investigations in animals have focused on memory; however, the effects of hormone therapy on executive function and attention processes have not been well studied. Thus, the purpose of this set of investigations was to assess the effects of estrogen therapy alone or with progesterone on executive and attention processes in middle-aged ovariectomized monkeys. Monkeys were preoperatively trained on a modified version of the Wisconsin card sort task and on a visual cued reaction time task. Hormone therapy was initiated at the time of ovariectomy and cognitive function was reassessed at 2, 12, and 24 weeks postoperatively. Relative to monkeys receiving either of the estrogen therapies, monkeys receiving placebo were impaired in their ability to shift a cognitive set in the Wisconsin card sort task and were impaired in shifting visuospatial attention in the visual cued reaction time task. Our findings are consistent with clinical studies that indicate that hormone therapy can improve executive function and attention processes in postmenopausal women.

The third versions of the guideline for treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology does not include puberty-delaying hormone therapy. It is recommended that feminizing/masculinizing hormone therapy and genital surgery should not be carried out until 18 year old and 20 year old, respectively. On the other hand, the sixth (2001) and the seventh (2011) versions of the standards of care for the health of transsexual, transgender, and gender nonconforming people of World Professional Association for Transgender Health (WPATH) recommend that transsexual adolescents (Tanner stage 2, [mainly 12-13 years of age]) are treated by the endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until age 16 years old, after which cross-sex hormones may be given. A questionnairing on 181 people with GID diagnosed in the Okayama University Hospital (Japan) showed that female to male (FTM) transsexuals hoped to begin masculinizing hormone therapy at age of 15.6 +/- 4.0 (mean +/- S.D.) whereas male to female (MTF) transsexuals hoped to begin feminizing hormone therapy as early as age 12.5 +/- 4.0, before presenting secondary sex characters. After confirmation of strong and persistent cross-gender identification, adolescents with GID should be treated with cross-gender hormone or puberty-delaying hormone to prevent developing undesired sex characters. These treatments may prevent transsexual adolescents from attempting suicide, being depressive, and refusing to attend school. Subsequent early breast and genital surgery may help being employed in desired sexuality.

Treatment of dwarfism with recombinant human insulin-like growth factor-1.

The growth hormone-IGF (insulin-like growth factor) system plays a central role in hormonal growth regulation. Recombinant human (rh) growth hormone (GH) has been available since the late 1980s for replacement therapy in GH-deficient patients and for the stimulation of growth in patients with short stature of various causes. Growth promotion by GH occurs in part indirectly through the induction of IGF-1 synthesis. In primary disturbances of IGF-1 production, short stature can only be treated with recombinant human IGF-1 (rhIGF-1). rhIGF-1 was recently approved for this indication but can also be used to treat other conditions. Selective review of the literature on IGF-1 therapy, based on a PubMed search. In children with severe primary IGF-1 deficiency (a rare condition whose prevalence is less than 1:10,000), the prognosis for final height is very poor (ca. 130 cm), and IGF-1 therapy is the appropriate form of pathophysiologically based treatment. There is no alternative treatment at present. The subcutaneous administration of IGF-1 twice daily in doses of 80 to 120 microg/kg accelerates growth and increases final height by 12 to 15 cm, according to current data. There is, however, a risk of hypoglycemia, as IGF-1 has an insulin-like effect. As treatment with IGF-1 is complex, this new medication should only be prescribed, for the time being, by experienced pediatric endocrinologists and diabetologists.

Background : Evidences shows that menopause affects women's health, but women's knowledge of proper care and maintenance is insufficient. To determine knowledge of hormone therapy (HT), reproductive physiology, and menopause in a population of 40-60 year old women. This cross-sectional study was conducted through a cluster sampling among 330 women in Yazd, Islamic Republic of Iran, in 2010. Data was collected using a questionnaire containing questions about reproductive physiology related to menopause and HT by interviewing. Inferential and descriptive statistics via SPSS.15 software were used for data analysis. Overall, 2.1% of women were current takers of HT, 13.4% had taken it in the past but had stopped and 84.5% had never taken hormone replacement therapy. Iranian women had low knowledge of HT, reproductive physiology, and menopause. Most of the women (85.5%) knew that hot flashes are common around menopause and only 77.2% knew decreasing estrogen production causes the menopause. They knew little about the effects of progestagens and the effects of HT on fertility. Logistic regression determined that age, educational level and BMI were the most important factors predicting use of HT after adjusting for other variables. Iranian women have a low HT usage rate and the majority of them are lacking of the knowledge about HT and menopause. Women need improved knowledge of the risks and benefits of HT as well as education about the reproductive system around menopause.

Gender identity disorder (transgenderism) is poorly understood from both mechanistic and clinical standpoints. Awareness of the condition appears to be increasing, probably because of greater societal acceptance and available hormonal treatment. Therapeutic options include hormone and surgical treatments but may be limited by insurance coverage because costs are high. For patients seeking male-to-female (MTF) change, hormone treatment includes estrogens, finasteride, spironolactone, and gonadotropin-releasing hormone (GnRH) analogs. Surgical options include feminizing genital and facial surgery, breast augmentation, and various fat transplantations. For patients seeking a female-to-male (FTM) gender change, medical therapy includes testosterone and GnRH analogs and surgical therapy includes mammoplasty and phalloplasty. Medical therapy for both FTM and MTF can be started in early puberty, although long-term effects are not known. All patients considering treatment need counseling and medical monitoring.

Radiation Therapy Did Not Induce Long-Term Changes in Rectal Mucosa: Results From the Randomized Scandinavian Prostate Cancer Group 7 Trial

Slagsvold, Jens Erik, E-mail: Jens.Erik.Slagsvold@stolav.no; Viset, Trond; Wibe, Arne

Purpose: To investigate long-term changes in the rectal mucosa after curative external beam radiation therapy in the treatment of prostate cancer. Methods and Materials: In the Scandinavian Prostate Cancer Group 7 trial, 880 men with locally advanced prostate cancer were randomized to hormonal therapy alone versus hormonal therapy plus radiation therapy to 70 Gy. A subcohort from this trial being randomized at our center (n=178) was invited to a study on late anorectal side effects during 2003-2005, approximately 5 years after treatment, including measuring health-reported quality of life and physician-assessed toxicity score by the Late Effects Normal Tissue Task Force/Subjective, Objective, Management, Analyticmore » (LENT/SOMA) and European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group score. Sixty-seven patients had a rectal mucosa biopsy. Sixty-four biopsies were included in the final analysis, of which 33 patients were randomized to hormonal treatment and 31 to hormonal treatment plus radiation therapy. The presence of fibrosis, number of capillaries, and lymphocyte infiltration was then evaluated by light microscopy. Results: The group receiving radiation therapy had significantly higher LENT/SOMA and function/bother scale scores than the group that only received hormonal treatment, but there was no significant difference in the presence of fibrosis, ectasia, number of capillaries in the lamina propria, or lymphocyte infiltration between the groups. Conclusion: Radiation therapy to 70 Gy to the prostate does not induce long-term microscopic mucosal changes in the rectum 5 years after treatment. This is in contrast to the general assumption that structural changes, including fibrosis, seen after radiation therapy include the mucosa. We speculate that the main late effects of radiation therapy on the structure of the rectum are located in the deeper layers of the rectal wall than the mucosa.« less

To suggest measures to optimize care to achieve a significant improvement, including options for saving financial resources. A comparison of the contents of texts related to transsexualism in the ICD-10, DSM-IV, and guidelines of the Spanish gender units with international standards of care for transgender persons and the last draft version of the DSM-5. Systematic revision of the literature related to the etiology and prevalence of transsexualism. Significant discrepancies have been found as regards the minimum time period for diagnosis, access to hormone replacement therapy and to genital surgery, and the requirement of the so-called real-life experience. Impact of sex hormones on the etiology of transsexualism and underestimation of its prevalence was confirmed. The access to hormonal and surgical treatment requires a profound review, and decentralization of transsexual care is recommended, because all university hospitals haves psychiatrists, clinical psychologists, and endocrinologists available. Although gender reassignment surgery also requires plastic surgery specialists, plastic surgeons currently receive training in this field. Copyright © 2012 SEEN. Published by Elsevier Espana.

Neuropsychological abnormalities in transsexual patients have been reported in comparison with subjects without gender identity disorder (GID), suggesting differences in underlying neurobiological processes. However, these results have not consistently been confirmed. Furthermore, studies on cognitive effects of cross-sex hormone therapy also yield heterogeneous results. We hypothesized that untreated transsexual patients differ from men without GID in activation pattern associated with a mental rotation task and that these differences may further increase after commencing of hormonal treatment. The present study investigated 11 male-to-female transsexual (MFTS) patients prior to cross-sex hormone therapy and 11 MFTS patients during hormone therapy in comparison with healthy men without GID. Using functional magnetic resonance imaging at 3-Tesla, a mental rotation paradigm with proven sexual dimorphism was applied to all subjects. Data were analyzed with SPM5. Patterns of brain activation associated with a mental rotation task. The classical mental rotation network was activated in all three groups, but significant differences within this network were observed. Men without GID exhibited significantly greater activation of the left parietal cortex (BA 40), a key region for mental rotation processes. Both transsexual groups revealed stronger activation of temporo-occipital regions in comparison with men without GID. Our results confirmed previously reported deviances of brain activation patterns in transsexual men from men without GID and also corroborated these findings in a group of transsexual patients receiving cross-sex hormone therapy. The present study indicates that there are a priori differences between men and transsexual patients caused by different neurobiological processes or task-solving strategies and that these differences remain stable over the course of hormonal treatment.

Our recent clinical observations put into question the routine hormonal therapy for pneumothorax recurrence prevention, in patients operated for catamenial pneumothorax (CP). Retrospective review of the treatment of four women operated for CP in a recent 32-months period. The four presented patients with CP represent 4.8 % of the overall number of patients operated for spontaneous pneumothorax and 19 % of women operated for pneumothorax in the same period. In all patients, typical multiple diaphragm holes existed. The involved part of the diaphragm was removed with diaphragm suture in three patients, whilst in one patient, a diaphragm placation was done. Endometriosis was histologically confirmed in two patients. During the follow-up period of 6-43 months, none of the patients underwent a postoperative hormonal therapy for different reasons, and in none of them the pneumothorax recurrence occurred. The clinical course of these patients, with the absence of the pneumothorax recurrence despite the omission of the hormonal treatment, suggests that the appropriateness of the routine hormonal treatment with gonadotrophin-releasing hormone analogues for 6-12 months, should be reconsidered and re-evaluated in further studies.

Pathogenesis of prostate cancer and hormone refractory prostate cancer

PubMed Central

Girling, J. S.; Whitaker, H. C.; Mills, I. G.; Neal, D. E.

2007-01-01

Prostate cancer is the second most common malignancy in males and the leading cause of cancer death. Prostate cancer is initially androgen dependent and relies upon the androgen receptor (AR) to mediate the effects of androgens. The AR is also the target for therapy using antiandrogens and LHRH analogues. However, all cancers eventually become androgen independent, often referred to as hormone refractory prostate cancer. The processes involved in this transformation are yet to be fully understood but research in this area has discovered numerous potential mechanisms including AR amplification, over-expression or mutation and alterations in the AR signaling pathway. This review of the recent literature examines the current knowledge and developments in the understanding of the molecular biology of prostate cancer and hormone refractory prostate cancer, summarizing the well characterized pathways involved as well as introducing new concepts that may offer future solutions to this difficult problem.

Important considerations in the management of Graves' disease in pregnant women.

Okosieme, Onyebuchi E; Lazarus, John H

2015-01-01

Graves' disease is an autoimmune disorder in which autoantibodies to the thyroid-stimulating hormone receptor cause hyperthyroidism through unregulated stimulation of the thyroid-stimulating hormone receptor. Effective management of Graves' disease in pregnancy must address the competing fetal and maternal priorities of controlling hyperthyroidism in the mother on the one hand, and on the other, minimizing the impact of maternal disease and antithyroid drugs on the well-being of the fetus. Optimal strategies for achieving this intricate balance are currently a source of continued debate among thyroid experts and studies in recent decades are now providing greater clarity into the risk posed to the unborn baby by the combination of biochemical, immunological and pharmacological hazards arising from Graves' disease and its therapy. This review summarizes the current best practice and highlights important considerations and areas of uncertainty in the management of Graves' disease in pregnant women.

Role of Aspirin in Breast Cancer Survival.

Chen, Wendy Y; Holmes, Michelle D

2017-07-01

Chemotherapy and hormonal therapy have significantly decreased breast cancer mortality, although with considerable side effects and financial costs. In the USA, over three million women are living after a breast cancer diagnosis and are eager for new treatments that are low in toxicity and cost. Multiple observational studies have reported improved breast cancer survival with regular aspirin use. Furthermore, pooled data from five large randomized trials of aspirin for cardiovascular disease showed that subjects on aspirin had decreased risk of cancer mortality and decreased risk of metastatic cancer. Although the potential mechanism for aspirin preventing breast cancer is not known, possible pathways may involve platelets, inflammation, cyclooxygenase (COX) 2, hormones, or PI3 kinase. This review article summarizes the current epidemiologic and clinical trial evidence as well as possible underlying mechanisms that justify current phase III randomized trials of aspirin to improve breast cancer survival.

Autoimmunity against the adrenal cortex is the leading cause of Addison's disease in industrialized countries, with prevalence estimates ranging from 93-220 per million in Europe. The immune-mediated attack on adrenocortical cells cripples their ability to synthesize vital steroid hormones and necessitates life-long hormone replacement therapy. The autoimmune disease etiology is multifactorial involving variants in immune genes and environmental factors. Recently, we have come to appreciate that the adrenocortical cell itself is an active player in the autoimmune process. Here we summarize the complex interplay between the immune system and the adrenal cortex and highlight unanswered questions and gaps in our current understanding of the disease.

Hormonal therapy to the brain-dead potential organ donor can include thyroid hormone (triiodothyronine [T3] or levothyroxine [T4]), corticosteroids, antidiuretic hormone, and insulin. Data on 66,629 donors (2000-2009) were retrospectively reviewed. Documentation on T3/T4 was available in 63,593 (study 1), but 23,469 had incomplete documentation of other hormones. In 40,124, details of all four hormones were recorded (study 2). In this cohort, group A (received T3/T4) consisted of 23,022, and group B (no T3/T4) consisted of 17,102 donors. A multivariate analysis was performed to determine whether age, sex, ethnicity, cause of death, body mass index, Organ Procurement Organization region, or other hormonal therapy influenced procurement. Posttransplantation organ graft survival at 1 and 12 months was compared. In study 1, 30,962 (48.69%) received T3/T4, providing a mean of 3.35 organs per donor, and 32,631 (51.31%) did not receive T3/T4, providing a mean of 2.97 organs per donor, an increase of 12.8% of organs from T3/T4-treated donors (P<0.0001). In study 2, group A provided a mean of 3.31 organs per donor and group B provided a mean of 2.87 organs per donor, an increase of 15.3% in group A (P<0.0001). T3/T4 therapy was associated with procurement of significantly greater numbers of hearts, lungs, kidneys, pancreases, and intestines, but not livers. Multivariate analysis indicated a beneficial effect of T3/T4 independent of other factors (P<0.0001). T3/T4 therapy of the donor was associated with improved posttransplantation graft survival or no difference in survival, except for pancreas recipient (but not graft) survival at 12 months in study 2. T3/T4 therapy results in more transplantable organs, with no detriment to posttransplantation graft survival.

Rare ovarian tumors include complex borderline ovarian tumors, sex-cord tumors, germ cell tumors, and rare epithelial tumors. Indications and modalities of fertility preservation, infertility management and contraindications for hormonal contraception or menopause hormone therapy are frequent issues in clinical practice. A panel of experts from the French national network dedicated to rare gynaecological cancers, and of experts in reproductive medicine and gynaecology have worked on guidelines about fertility preservation, contraception and menopause hormone therapy in women treated for ovarian rare tumors. A panel of 39 experts from different specialties contributed to the preparation of the guidelines, following the DELPHI method (formal consensus method). Statements were drafted after a systematic literature review, and then rated through two successive rounds. Thirty-five recommendations were selected, and concerned indications for fertility preservation, contraindications for ovarian stimulation (in the context of fertility preservation or for infertility management), contraceptive options (especially hormonal ones), and menopause hormone therapy for each tumor type. Overall, prudence has been recommended in the case of potentially hormone-sensitive tumors such as sex cord tumors, serous and endometrioid low-grade adenocarcinomas, as well as for high-risk serous borderline ovarian tumors. In the context of a scarce literature, a formal consensus method allowed the elaboration of guidelines, which will help clinicians in the management of these patients.

The 21-gene breast cancer assay (Oncotype DX(®); Genomic Health, Inc.) is a validated diagnostic test that predicts the likelihood of adjuvant chemotherapy benefit and 10-year risk of distant recurrence in patients with hormone-receptor-positive, human epidermal growth receptor 2-negative, early-stage breast cancer. The aim of this analysis was to evaluate the cost-effectiveness of using the assay to inform adjuvant chemotherapy decisions in Mexico. A Markov model was developed to make long-term projections of distant recurrence, survival, and direct costs in scenarios using conventional diagnostic procedures or the 21-gene assay to inform adjuvant chemotherapy recommendations. Transition probabilities and risk adjustment were taken from published landmark trials. Costs [2011 Mexican Pesos (MXN)] were estimated from an Instituto Mexicano del Seguro Social perspective. Costs and clinical benefits were discounted at 5% annually. Following assay testing, approximately 66% of patients previously receiving chemotherapy were recommended to receive hormone therapy only after consideration of assay results. Furthermore, approximately 10% of those previously allocated hormone therapy alone had their recommendation changed to add chemotherapy. This optimized therapy allocation led to improved mean life expectancy by 0.068 years per patient and increased direct costs by MXN 1707 [2011 United States Dollars (USD) 129] per patient versus usual care. This is equated to an incremental cost-effectiveness ratio (ICER) of MXN 25,244 (USD 1914) per life-year gained. In early-stage breast cancer patients in Mexico, guiding decision making on adjuvant therapy using the 21-gene assay was projected to improve life expectancy in comparison with the current standard of care, with an ICER of MXN 25,244 (USD 1914) per life-year gained, which is within the range generally considered cost-effective.

Lifestyle risk management--a qualitative analysis of women's descriptions of taking hormone therapy following surgically induced menopause.

PubMed

Crowe, Marie; Burrell, Beverly; Whitehead, Lisa

2012-08-01

This article is a report of a study that examined how women describe their decisions in relation to the use of menopausal hormone therapy following surgical menopause. Women who have had a surgically induced menopause generally experience more intense menopausal symptoms than natural menopause and are regularly prescribed menopausal hormone therapy. Since 2002 the risks associated with this therapy have been widely reported. This study is a qualitative analysis of semi-structured interviews between March and May 2009 with 30 participants who had experienced surgical menopause and were, or had in the past, taken menopausal hormone therapy. This was a community sample recruited in Christchurch, New Zealand. A risk management theoretical approach underpinned the analysis. The womens' descriptions of managing the risks associated with menopausal therapy fell into two main themes: Life has to go on and Waiting for someone to tell me. All these women had either made an active decision to continue on treatment because of the impact of menopausal symptoms or took their doctor's advice to continue. A less dominant theme but one that was also evident was Relying on my body to get me through in which the women had decided to discontinue treatment because they regarded it as unnatural. The study provided insights into how women utilize an experiential reasoning process to manage the health and lifestyle risks associated with taking menopausal hormone therapy. Nurses need to be aware of how this process influences women's reasoning processes when working with women following surgical menopause. © 2011 Blackwell Publishing Ltd.

Menopausal hormone therapy (HT) has shown benefits for women; however, associated drawbacks (i.e. risks, costs, fears) have currently determined its low use. To determine the prevalence of current HT use among mid-aged women and describe the characteristics of those who have never used, have abandoned or are currently using HT. In addition, reasons for not using HT were analyzed. This was a cross-sectional study that analyzed a total of 6731 otherwise healthy women (45-59 years old) of 15 cities in 11 Latin American countries. Participants were requested to fill out the Menopause Rating Scale (MRS) and a questionnaire containing sociodemographic data and items regarding the menopause and HT use. The prevalence of current HT use was 12.5%. Oral HT (43.7%) was the most frequently used type of HT, followed by transdermal types (17.7%). The main factors related to the current use of HT included: positive perceptions regarding HT (odds ratio (OR) 11.53, 95% confidence interval (CI) 9.41-14.13), being postmenopausal (OR 3.47, 95% CI 2.75-4.36) and having a better socioeconomic level. A total of 48.8% of surveyed women had used HT in the past, but abandoned it due to symptom improvement or being unconcerned; fear of cancer or any other secondary effects were also reported but in less than 10%. Among women who had never used HT, 28% reported the lack of medical prescription as the main reason, followed by the absence of symptoms (27.8%). Among those reporting lack of prescription as the main reason for not using HT, 30.6% currently had severe menopausal symptoms (total MRS score > 16); 19.5% of women were using alternative 'natural' therapies, with 35.1% of them displaying severe menopausal symptoms as compared to a 22.5% observed among current HT users. The use of HT has not regained the rates observed a decade ago. Positive perceptions regarding HT were related to a higher use. Lack of medical prescription was the main reason for not using HT among non-users, many of whom were currently displaying severe menopausal symptoms.

A positive correlation between the circulating growth hormone levels and the nutritional status was reported in 9 children of both sexes, aged 1 to 6 years, suffering from 2nd degree malnutrition. The mean serum insulin levels, the mean urinary 17-KS and 17-OHCS levels were low before the dietary therapy. No significant correlation between the levels of these hormones and the nutritional status was found. The hormone levels gradually returned to normal after the dietary therapy and the nutritional status of the children improved, according to the observed biochemical, clinical and anthropometric data.

The effect of hormones on the lower urinary tract.

PubMed

Robinson, Dudley; Toozs-Hobson, Philip; Cardozo, Linda

2013-12-01

The female genital and lower urinary tracts share a common embryological origin, arising from the urogenital sinus and both are sensitive to the effects of the female sex steroid hormones throughout life. Estrogen is known to have an important role in the function of the lower urinary tract and estrogen and progesterone receptors have been demonstrated in the vagina, urethra, bladder and pelvic floor musculature. In addition estrogen deficiency occurring following the menopause is known to cause atrophic change and may be associated with lower urinary tract symptoms such as frequency, urgency, nocturia, urgency incontinence and recurrent infection. These may also co-exist with symptoms of urogenital atrophy such as dyspareunia, itching, vaginal burning and dryness. Epidemiological studies have implicated estrogen deficiency in the aetiology of lower urinary tract symptoms with 70% of women relating the onset of urinary incontinence to their final menstrual period. Whilst for many years systemic and vaginal estrogen therapy was felt to be beneficial in the treatment of lower urinary and genital tract symptoms this evidence has recently been challenged by large epidemiological studies investigating the use of systemic hormone replacement therapy as primary and secondary prevention of cardiovascular disease and osteoporosis. The aim of this paper is to examine the effect of the sex hormones, estrogen and progesterone, on the lower urinary tract and to review the current evidence regarding the role of systemic and vaginal estrogens in the management of lower urinary tract symptoms and urogenital atrophy.

A luteinizing hormone-releasing hormone (LH-RH) agonist and tamoxifen (TAM) are used in hormonal therapy following pre- and post-operative chemotherapy in pre-menopausal advanced breast cancer patients who are positive for hormone receptors. However, it remains to be clarified how often patients recover menstruation after long-term LH-RH agonist plus TAM therapy. In this study, the incidence of menstruation recovery after therapy was examined. The subjects included 125 pre-menopausal patients with breast cancer who were positive for hormone receptors and had undergone surgery at our institution. They were treated with four cycles of the CEF regimen and four cycles of docetaxel (Doc) before surgery as adjuvant chemotherapy. Thereafter, they were treated with an LH-RH agonist plus TAM for 24 months and followed to determine menstruation recovery. Menstruation resumed in 24 cases (19.2%) after the last LH-RH agonist treatment session. It took 7.3 ± 2.8 months for the patients to recover menstruation. The rate of menstruation recovery was 42.1% in patients aged 40 or younger and 9.2% in those aged 41 or older; the difference was significant. The period until menstruation recovery tended to be longer in older patients at the end of treatment. The menstruation recovery rate after therapy was higher in younger women. However, since ovarian function may be lost even in younger patients, the potential consequences of this therapy should be fully explained beforehand to patients who may wish to become pregnant.

Hypnosis for hot flashes among postmenopausal women study: A study protocol of an ongoing randomized clinical trial

PubMed Central

2011-01-01

Background Hot flashes are a highly prevalent problem associated with menopause and breast cancer treatments. The recent findings from the Women's Health Initiative have important implications for the significance of a non-hormonal, mind-body intervention for hot flashes in breast cancer survivors. Women who take hormone therapy long-term may have a 1.2 to 2.0 fold increased risk of developing breast cancer. In addition, it is now known that hormone therapy with estrogen and progestin is associated with increased risk of cardiovascular disease and stroke. Currently there are limited options to hormone replacement therapy as non-hormonal pharmacological agents are associated with only modest activity and many adverse side effects. Because of this there is a need for more alternative, non-hormonal therapies. Hypnosis is a mind-body intervention that has been shown to reduce self-reported hot flashes by up to 68% among breast cancer survivors, however, the use of hypnosis for hot flashes among post-menopausal women has not been adequately explored and the efficacy of hypnosis in reducing physiologically measured hot flashes has not yet been determined. Methods/design A sample of 180 post-menopausal women will be randomly assigned to either a 5-session Hypnosis Intervention or 5-session structured-attention control with 12 week follow-up. The present study will compare hypnosis to a structured-attention control in reducing hot flashes (perceived and physiologically monitored) in post-menopausal women in a randomized clinical trial. Outcomes will be hot flashes (self-report daily diaries; physiological monitoring; Hot Flash Related Daily Interference Scale), anxiety (State-Trait Anxiety Inventory; Hospital Anxiety and Depression Scale (HADS); anxiety visual analog scale (VAS rating); depression (Center for Epidemiologic Studies Depression Scale), sexual functioning (Sexual Activity Questionnaire), sleep quality (Pittsburgh Sleep Quality Index) and cortisol. Discussion This study will be the first full scale test of hypnosis for hot flashes; one of the first studies to examine both perceived impact and physiologically measured impact of a mind-body intervention for hot flashes using state-of-the-art 24 hour ambulatory physiological monitoring; the first study to examine the effect of hypnosis for hot flashes on cortisol; and the first investigation of the role of cognitive expectancies in treatment of hot flashes in comparison to a Structured-Attention Control. Trial Registration This clinical trial has been registered with ClinicalTrials.gov, a service of the U.S. National Institutes of Health, ClinicalTrials.gov Identifier: NCT01293695. PMID:21989181

Cancer Treatment Using Peptides: Current Therapies and Future Prospects

This paper discusses the role of peptides in cancer therapy with special emphasis on peptide drugs which are already approved and those in clinical trials. The potential of peptides in cancer treatment is evident from a variety of different strategies that are available to address the progression of tumor growth and propagation of the disease. Use of peptides that can directly target cancer cells without affecting normal cells (targeted therapy) is evolving as an alternate strategy to conventional chemotherapy. Peptide can be utilized directly as a cytotoxic agent through various mechanisms or can act as a carrier of cytotoxic agents and radioisotopes by specifically targeting cancer cells. Peptide-based hormonal therapy has been extensively studied and utilized for the treatment of breast and prostate cancers. Tremendous amount of clinical data is currently available attesting to the efficiency of peptide-based cancer vaccines. Combination therapy is emerging as an important strategy to achieve synergistic effects in fighting cancer as a single method alone may not be efficient enough to yield positive results. Combining immunotherapy with conventional therapies such as radiation and chemotherapy or combining an anticancer peptide with a nonpeptidic cytotoxic drug is an example of this emerging field.

The objective of this study was to document the differences in testosterone (T) levels between crizotinib-treated and noncrizotinib-treated patients with metastatic nonsmall cell lung cancer (NSCLC). Testosterone levels were measured in 19 men with metastatic NSCLC who received crizotinib and in 19 men with metastatic NSCLC who did not receive crizotinib. Clinical characteristics of the patients were compared, and additional hormone assays were performed as appropriate. Two patients who began crizotinib and 4 patients who had dose interruptions or who stopped crizotinib therapy had serial hormone measurements, permitting the documentation of dynamic hormone changes on and off crizotinib treatment. Total T levels were low (<241 ng/dL) in 19 of 19 (100%) crizotinib-treated men and in 6 of 19 men (32%) with metastatic NSCLC who did not receive crizotinib (mean T levels, 131 ng/dL and 311 ng/dL, respectively; P = .0002). Only 1 in 5 patients who had anaplastic lymphoma kinase (ALK) gene rearrangements and had not yet received crizotinib had low T. The initiation of crizotinib in 2 patients who had previously normal T levels was associated with a rapid decreases in T and in luteinizing hormone and follicle stimulating hormone levels within 14 to 21 days. Discontinuation of crizotinib led to increases back to normal T levels. Crizotinib therapy caused rapid suppression of T levels in men. The current results indicated that the site of action must include a central (hypothalamic or pituitary) effect, but additional direct testicular effects could not be excluded. Further work is required to assess the correlation between low T levels and crizotinib side effects as well as the exact molecular mechanism and site of drug toxicity.

Biologicals targeting the interleukin (IL)-1β or IL-6 pathway are becoming prime choices for the treatment of children with systemic juvenile idiopathic arthritis (sJIA). Up to 1 in 3 sJIA children receiving such treatment continues to have inflammatory activity and to require supra-physiological glucocorticoid doses which may reduce growth velocity for years and may lead to an extremely short stature for age, if not for life. Currently, there is no long-term proposal to normalize the adult height of these children with sJIA. We present long-term (up to 10 years), proof-of-concept evidence that the adult stature and adipose body composition of short sJIA children can be normalized with a hormonal combination strategy: (i) pubertal onset is postponed with a gonadotropin-releasing hormone analog (triptorelin) until a minimum height is reached, or until prepubertal growth is exhausted, and (ii) height gain is promoted with growth hormone (≈50 μg/kg/day), once inflammation is under control and high glucocorticoid doses are no longer needed. The latter treatment takes advantage of the window of relative glucocorticoid deficiency, which is known to open after prolonged glucocorticoid administration, and to be uniquely favorable to height gain. A long-term combination of biological and hormonal treatments for short sJIA children can be guided by a simple concept that involves (i) postponement of pubertal development and (ii) growth-promoting therapy after the episodes of major inflammation and high-dose glucocorticoid treatment. Limited long-term experience in short sJIA children suggests that this strategy leads consistently - albeit late - to a normal adult stature. © 2018 S. Karger AG, Basel.

To evaluate the effects of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D), the angiotensinogen M235T and the angiotensin II type 1 receptor A1166C polymorphisms, and hormone therapy used on endothelial function in postmenopausal women without manifestation of coronary artery disease. Sixty-four postmenopausal women (42 hormone therapy users and 22 hormone therapy nonusers) without clinical manifestation of coronary artery disease were evaluated using external vascular ultrasonography to measure endothelium-dependent (hyperemic response, flow-mediated dilatation) and -independent (nitroglycerin) dilatation. Genotypes were determined by polymerase chain reaction amplification. Women with the ACE-DD genotype displayed a lower flow-mediated dilatation compared to those with the ACE-II genotype (8.4% +/- 3.9% vs 12.6% +/- 5.4%, P = 0.04). Endothelial function was not associated with the angiotensinogen M235T and anglotensin II type 1 receptor A1166C polymorphisms. ACE polymorphism seems to modulate endothelial function among postmenopausal women without hormone therapy (8.2% +/- 5.1% vs 18.4% +/- 5.9% for the DD and the II genotype, respectively, P = 0.02). However, in hormone therapy users, flow-mediated dilatation was similar according to the ACE genotypes. Our findings suggest that ACE-I/D polymorphism is related to endothelial dysfunction in postmenopausal women. Furthermore, a potential interaction between estrogen users and ACE polymorphism on endothelial function may be present.

Objective Women with breast cancer have been found to have poorer cognitive function before the initiation of systemic adjuvant therapy than their age- and education-matched counterparts. The basis for this may partly include hormone exposure during the course of a woman’s life. Methods We compared cognitive function between postmenopausal women with breast cancer before the initiation of systemic adjuvant therapy and healthy age- and education-matched postmenopausal women and examined whether factors related to lifetime exposure to hormones predicted cognitive function before therapy. Results We found that, compared with healthy women, women with breast cancer had poorer memory (P = 0.05) and attention (P = 0.006). Controlling for the covariates age and estimated verbal intelligence, we found that factors related to greater lifetime hormone exposure (oral contraceptive use, greater years since menopause, and longer duration of hormone therapy) predicted cognitive function (executive function, verbal learning and memory, attention, psychomotor efficiency, and visual sustained attention) in women with and without breast cancer but did not explain the differences in cognitive function observed at pretreatment in women with breast cancer. Conclusions Other factors may explain the poorer pretreatment cognitive function in women with breast cancer, including persistent effects of surgical operation and anesthesia, sleep problems, and tumor-related factors. Additional studies are needed to explicate the basis of poorer pretherapy cognitive function in this population. PMID:23481123

Common regimens of HRT therapy are reviewed, including common routes of hormone administration. Inconsistent patterns of HRT use are discussed, including the reasons women most often give for discontinuing hormone therapies. Specific issues related to misperceptions and fears regarding HRT are clarified, and specific, focused patient education formats are discussed to address women's common concerns about HRT. Obstacles to HRT use are elucidated, with suggestions for clinicians about how to communicate more effectively with women: clinicians must focus on emotional and physical aspects of HRT choices and tailor therapies to the individual patient. Discussing frankly the very serious concerns of women regarding the association between lobular breast cancer and endometrial cancer is important; discussing and preparing women for possible side effects helps patients cope better if and when side effects occur. Finally, offering a wide variety of HRT therapies provides women with a broader choice if an initial regimen is unsuccessful.

Background Postmenopausal hormone therapy with conjugated equine estrogens (CEE) may adversely affect older women’s cognitive function. It is not known whether this extends to younger women. Methods 1,326 postmenopausal women, who had begun treatment in two randomized placebo-controlled clinical trials of hormone therapy when aged 50–55 years, were assessed with an annual telephone-administered cognitive battery that included measures of global (primary outcome) and domain-specific cognitive functions (verbal memory, attention, executive function, verbal fluency, and working memory). The clinical trials in which they participated had compared 0.625 mg CEE with or without 2.5 mg medroxyprogesterone acetate (MPA) over an average of 7.0 years. Cognitive testing was conducted an average of 7.2 years following the end of the trials, when women had mean age 67.2 years, and repeated one year later. Results Global cognitive function scores from women who had been assigned to CEE-based therapies were similar to those from women assigned to placebo: mean [95% confidence interval] intervention effect of 0.02 [−0.08,0.12]standard deviation units (p=0.66). Similarly, no overall differences were found for any individual cognitive domain (all p>0.15). Pre-specified subgroup analyses found some evidence that CEE-based therapies may have adversely affected verbal fluency among women who had prior hysterectomy or prior use of hormone therapy: mean treatment effects of −0.17 [−0.33, −0.02] and −0.25 [−0.42, −0.08], respectively, however this may be a chance finding. We are not able to address whether initiating hormone therapy during the menopause and maintaining therapy until any symptoms are passed affects cognitive function, either in the short or longer term. Conclusions CEE-based therapies produced no overall sustained benefit or risk to cognitive function when administered to postmenopausal women aged 50–55 years. PMID:23797469

Díez, Juan J.; Sangiao-Alvarellos, Susana; Cordido, Fernando

2018-01-01

Pharmacological treatment of growth hormone deficiency (GHD) in adults began in clinical practice more than 20 years ago. Since then, a great volume of experience has been accumulated on its effects on the symptoms and biochemical alterations that characterize this hormonal deficiency. The effects on body composition, muscle mass and strength, exercise capacity, glucose and lipid profile, bone metabolism, and quality of life have been fully demonstrated. The advance of knowledge has also taken place in the biological and molecular aspects of the action of this hormone in patients who have completed longitudinal growth. In recent years, several epidemiological studies have reported interesting information about the long-term effects of GH replacement therapy in regard to the possible induction of neoplasms and the potential development of diabetes. In addition, GH hormone receptor polymorphism could potentially influence GH therapy. Long-acting GH are under development to create a more convenient GH dosing profile, while retaining the excellent safety, efficacy, and tolerability of daily GH. In this article we compile the most recent data of GH replacement therapy in adults, as well as the molecular aspects that may condition a different sensitivity to this treatment. PMID:29562611

Castration resistance occurs in most patients with metastatic hormone-sensitive prostate cancer who are receiving androgen-deprivation therapy. Replacing androgens before progression of the disease is hypothesized to prolong androgen dependence. Men with newly diagnosed, metastatic, hormone-sensitive prostate cancer, a performance status of 0 to 2, and a prostate-specific antigen (PSA) level of 5 ng per milliliter or higher received a luteinizing hormone-releasing hormone analogue and an antiandrogen agent for 7 months. We then randomly assigned patients in whom the PSA level fell to 4 ng per milliliter or lower to continuous or intermittent androgen deprivation, with patients stratified according to prior or no prior hormonal therapy, performance status, and extent of disease (minimal or extensive). The coprimary objectives were to assess whether intermittent therapy was noninferior to continuous therapy with respect to survival, with a one-sided test with an upper boundary of the hazard ratio of 1.20, and whether quality of life differed between the groups 3 months after randomization. A total of 3040 patients were enrolled, of whom 1535 were included in the analysis: 765 randomly assigned to continuous androgen deprivation and 770 assigned to intermittent androgen deprivation. The median follow-up period was 9.8 years. Median survival was 5.8 years in the continuous-therapy group and 5.1 years in the intermittent-therapy group (hazard ratio for death with intermittent therapy, 1.10; 90% confidence interval, 0.99 to 1.23). Intermittent therapy was associated with better erectile function and mental health (P<0.001 and P = 0.003, respectively) at month 3 but not thereafter. There were no significant differences between the groups in the number of treatment-related high-grade adverse events. Our findings were statistically inconclusive. In patients with metastatic hormone-sensitive prostate cancer, the confidence interval for survival exceeded the upper boundary for noninferiority, suggesting that we cannot rule out a 20% greater risk of death with intermittent therapy than with continuous therapy, but too few events occurred to rule out significant inferiority of intermittent therapy. Intermittent therapy resulted in small improvements in quality of life. Copyright © 2013 Elsevier Inc. All rights reserved.

The role of thyroid hormone in trophoblast function, early pregnancy maintenance, and fetal neurodevelopment.

To review the literature on the roles of thyroid hormone in trophoblast function, early pregnancy maintenance, and fetal neurodevelopment. MEDLINE was searched for English-language papers published from 1971 to 2003, using the key words "brain," "hypothyroidism," "placenta," "pregnancy," "threatened abortion," "thyroid hormone," "thyroid hormone receptor," "thyroid hormone replacement therapy," "thyroid hormone-responsive gene," and "trophoblast." Transplacental transfer of thyroid hormone occurs before the onset of fetal thyroid hormone secretion. Thyroid hormone receptors and iodothyronine deiodinases are present in the placenta and the fetal central nervous system early in pregnancy, and thyroid hormone plays a crucial role both in trophoblast function and fetal neurodevelopment. Maternal hypothyroxinemia is associated with a high rate of spontaneous abortion and long-term neuropsychological deficits in children born of hypothyroid mothers. Maternal iodine deficiency also causes a wide spectrum of neuropsychological disorders in children, ranging from subclinical deficits in cognitive motor and auditory functions to hypothyroid-induced cognitive impairment in infants. However, these conditions are preventable when iodine supplementation is initiated before the second trimester. Although thyroid hormone replacement therapy is effective for reducing the adverse effects complicated by maternal hypothyroidism, the appropriate dose of thyroid hormone is mandatory in protecting the early stage of pregnancy. Close monitoring of maternal thyroid hormone status and ensuring adequate maternal thyroid hormone levels in early pregnancy are of great importance to prevent miscarriage and neuropsychological deficits in infants.

Pituitary cell differentiation from stem cells and other cells: toward restorative therapy for hypopituitarism?

PubMed

Willems, Christophe; Vankelecom, Hugo

2014-01-01

The pituitary gland, key regulator of our endocrine system, produces multiple hormones that steer essential physiological processes. Hence, deficient pituitary function (hypopituitarism) leads to severe disorders. Hypopituitarism can be caused by defective embryonic development, or by damage through tumor growth/resection and traumatic brain injury. Lifelong hormone replacement is needed but associated with significant side effects. It would be more desirable to restore pituitary tissue and function. Recently, we showed that the adult (mouse) pituitary holds regenerative capacity in which local stem cells are involved. Repair of deficient pituitary may therefore be achieved by activating these resident stem cells. Alternatively, pituitary dysfunction may be mended by cell (replacement) therapy. The hormonal cells to be transplanted could be obtained by (trans-)differentiating various kinds of stem cells or other cells. Here, we summarize the studies on pituitary cell regeneration and on (trans-)differentiation toward hormonal cells, and speculate on restorative therapies for pituitary deficiency.

Current therapy and drug pipeline for the treatment of patients with acromegaly.

PubMed

Kumar, Sampath Satish; Ayuk, John; Murray, Robert D

2009-04-01

Acromegaly is a multisystem disease resulting from chronic exposure to supraphysiological levels of growth hormone (GH), and is associated with significant morbidity and excess mortality. The etiology is almost exclusively an underlying pituitary adenoma. Current therapeutic interventions include surgery, radiotherapy, and medical therapy. Despite surgery, around 50% of patients fail to achieve the biochemical targets shown to correlate with normalization of mortality rates. Radiotherapy is efficacious in controlling tumor growth and GH secretion; still, achievement of biochemical targets may take up to a decade and a number of safety issues have been raised with this treatment modality. Medical therapy, therefore, has an important role as adjuvant therapy in patients who fail to achieve control with surgery, or while awaiting the effects of radiotherapy to be realized. Furthermore, medical therapy is increasingly being used as primary therapy. Current medical therapies include dopaminergic agonists, somatostatin analogs, and GH receptor (GHR) antagonists. Dopaminergic agonists achieve biochemical targets in up to 30% of patients, and somatostatin analogs in around 60%. The currently available GHR antagonist pegvisomant effectively controls insulin-like growth factor-I levels in over 90% of patients; however, it has no effect on the tumor itself and has considerable financial implications. Research into optimizing the somatostatin and dopaminergic systems has led to promising advances in agonist development. Moieties with selectivity for various combinations of somatostatin receptor subtype receptors have been examined, along with molecules that additionally show high affinity for the dopaminergic D2 receptor. Of the molecules studied in vitro, only pasireotide (SOM230) and BIM-23A760 are currently undergoing further development. Other innovations to improve convenience of currently available drugs are also being investigated. Significant advances in under standing of the somatostatin and dopaminergic system have aided drug development. This may lead to new clinically available therapies enabling control of acromegaly in a larger proportion of patients, and at an earlier stage in their disease management.

To examine whether significant depressive symptoms in postmenopausal women increases the risk of subsequent mild cognitive impairment (MCI) and dementia. Prospective cohort study. Thirty nine of the 40 Women's Health Initiative (WHI) clinical centers that participated in a randomized clinical trial of hormone therapy. Six thousand three hundred seventy-six postmenopausal women without cognitive impairment aged 65 to 79 at baseline. Depressive disorders were assessed using an eight-item Burnam algorithm and followed annually for a mean period of 5.4 years. A central adjudication committee classified the presence of MCI and probable dementia based on an extensive neuropsychiatric examination. Eight percent of postmenopausal women in this sample reported depressive symptoms above a 0.06 cut point on the Burnam algorithm. Depressive disorder at baseline was associated with greater risk of incident MCI (hazard ratio (HR)=1.98, 95% confidence interval (CI)=1.33-2.94), probable dementia (HR=2.03, 95% CI=1.15-3.60), and MCI or probable dementia (HR=1.92, 95% CI=1.35-2.73) after controlling for sociodemographic characteristics, lifestyle and vascular risk factors, cardiovascular and cerebrovascular disease, antidepressant use, and current and past hormone therapy status. Assignment to hormone therapy and baseline cognitive function did not affect these relationships. Women without depression who endorsed a remote history of depression had a higher risk of developing dementia. Clinically significant depressive symptoms in women aged 65 and older are independently associated with greater incidence of MCI and probable dementia. © 2011, Copyright the Authors.

Although sexual health after genital surgery is an important outcome factor for many transsexual persons, little attention has been attributed to this subject. To provide data on quality of life and sexual health after sex reassignment surgery (SRS) in transsexual men. A single-center, cross-sectional study in 49 transsexual men (mean age 37 years) after long-term testosterone therapy and on average 8 years after SRS. Ninety-four percent of the participants had phalloplasty. Self-reported physical and mental health using the Dutch version of the Short Form-36 Health Survey; sexual functioning before and after SRS using a newly constructed specific questionnaire. Compared with a Dutch reference population of community-dwelling men, transsexual men scored well on self-perceived physical and mental health. The majority reported having been sexually active before hormone treatment, with more than a quarter having been vaginally penetrated frequently before starting hormone therapy. There was a tendency toward less vaginal involvement during hormone therapy and before SRS. Most participants reported an increase in frequency of masturbation, sexual arousal, and ability to achieve orgasm after testosterone treatment and SRS. Almost all participants were able to achieve orgasm during masturbation and sexual intercourse, and the majority reported a change in orgasmic feelings toward a more powerful and shorter orgasm. Surgical satisfaction was high, despite a relatively high complication rate. Results of the current study indicate transsexual men generally have a good quality of life and experience satisfactory sexual function after SRS. © 2011 International Society for Sexual Medicine.

To investigate the role of estrogen deprivation and replacement in amenorrheic and nonamenorrheic dancers on hormone therapy and calcium. Clinical, placebo-controlled, randomized trial study.Healthy volunteers in an academic research environment. Fifty-five dancers (mean age: 22.0 +/- 4.6, age at menarche: 14.7 +/- 2.3 years), including 24 amenorrheics. Amenorrheics were randomized in a controlled trial to receive placebo or Premarin, 0.625 mg for 25 days monthly, with Provera, 10 mg, for 10 of these 25 days (hormone therapy) for 2 years. These women were compared to normally menstruating controls. The study participants also received 1250 mg of calcium per day. Bone mineral density (BMD) measured at the foot, wrist, and lumbar spine. Our overall results showed no difference in BMD between the treated or placebo groups, indicating that hormone therapy did not change or normalize BMD when compared to normals. Five patients (all on placebo) who resumed menses during the study showed an increase in BMD without normalization. These findings suggest that mechanisms other than hypoestrogenism may be involved with the osteopenia associated with exercise-induced amenorrhea.

A series of new technologies and adjuvant therapies have been advocated in order to improve the success of IVF treatment. Dehydro-epiandrostenedione, growth hormones, Coenzyme Q 10, calcium ionosphores, immune therapy, heparin, low-dose aspirin, and vasodilators are among commonly prescribed pharmacological adjuvants. New technologies that are proposed to improve IVF outcomes include advanced sperm selection procedures, time- lapse embryo monitoring, preimplantation genetic screening, assisted hatching endometrial injury or embryo-glue. This review looked into current evidence to justify the use of these co-interventions and whether some of them can still be offered while awaiting more robust evidence to con rm or refute their role.

Cheung, A P; Wren, B G

To evaluate the cost-effectiveness of hormone replacement therapy in the menopause with particular reference to osteoporotic fracture and myocardial infarction. The multiple-decrement form of the life table was the mathematical model used to follow women of age 50 through their lifetime under the "no hormone replacement" and "hormone replacement" assumptions. Standard demographic and health economic techniques were used to calculate the corresponding lifetime differences in direct health care costs (net costs in dollars) and health effects ("net effectiveness" in terms of life expectancy and quality, in "quality-adjusted life-years"). This was then expressed as a cost-effectiveness ratio or the cost ($) per quality-adjusted life-year (QALY) for each of the chosen hormone replacement regimens. All women of age 50 in New South Wales, Australia (n = 27,021). The analysis showed that the lifetime net increments in direct medical care costs were largely contributed by hormone drug and consultation costs. Hormone replacement was associated with increased quality-adjusted life expectancy, a large percentage of which was attributed to a relief of menopausal symptoms. Cost-effectiveness ratios ranged from under 10,000 to over a million dollars per QALY. Factors associated with improved cost-effectiveness were prolonged treatment duration, the presence of menopausal symptoms, minimum progestogen side effects (in the case of oestrogen with progestogen regimens), oestrogen use after hysterectomy and the inclusion of cardiac benefits in addition to fracture prevention. Hormone replacement therapy for symptomatic women is cost-effective when factors that enhance its efficiency are considered. Short-term treatment of asymptomatic women for prevention of osteoporotic fractures and myocardial infarction is an inefficient use of health resources. Cost-effectiveness of hormone replacement in asymptomatic women is dependent on the magnitude of cardiac benefits associated with hormone use and the treatment duration.

Hormone replacement therapy in young women with primary ovarian insufficiency and early menopause

Primary ovarian insufficiency (POI) is a rare but important cause of ovarian hormone deficiency and infertility in women. In addition to causing infertility, POI is associated with multiple health risks, including bothersome menopausal symptoms, decreased bone density and increased risk of fractures, early progression of cardiovascular disease, psychological impact that may include depression, anxiety, and decreased perceived psychosocial support, potential early decline in cognition, and dry eye syndrome. Appropriate hormone replacement therapy to replace premenopausal levels of ovarian sex steroids is paramount to increasing quality of life for women with POI and ameliorating associated health risks. In this review, we discuss POI and complications associated with this disorder, as well as safe and effective hormone replacement therapy options. To decrease morbidity associated with POI, we recommend using HRT formulations that most closely mimic normal ovarian hormone production and continuing HRT until the normal age of natural menopause, ~50 years. We address special populations of women with POI, including women with Turner Syndrome, women with increased risk of breast or ovarian cancer, women approaching the age of natural menopause, and breastfeeding women.

Recent studies have reported an increased risk of certain cancers associated with hormone replacement therapy (HRT), possibly due to stimulation of estrogen receptors. Since estrogen receptors are expressed on certain hematopoietic cells, it is possible that HRT use may also increase the risk of leukemia. A cohort of 37,172 post-menopausal Iowa women ages 55-69 years with no history of prior cancer was linked annually to the population-based state cancer registry through 2001. In addition to other self-reported cancer risk factors, participants were asked about current and former use of HRT in 1986 and on four subsequent follow-up questionnaires. A total of 201 cases of leukemia were identified over 16 years of follow-up including 74 acute myeloid leukemias (AMLs) and 87 chronic lymphocytic leukemias (CLLs). Compared to never users of HRT at study baseline, current [multivariate relative risk (RR), 1.09; 95% confidence interval (CI) 0.70-1.71)] and former users (RR=0.82, 95% CI=0.59-1.15) were at no increased risk of developing leukemia. For AML, current users also had no increased risk (RR=0.83, 95% CI=0.37-1.84) and there was a suggestion that former users had a slightly decreased risk (RR=0.66, 95% CI=0.37-1.17). For CLL, all RRs were around unity. We conclude that HRT is unlikely to be an appreciable risk factor for leukemia.

Our objective was to assess the contribution of lean body mass (LBM) and fat body mass (FBM) to areal bone mineral density (aBMD) in women during the years surrounding menopause. We used a 12-year observational design. Participants included 75 Caucasian women who were premenopausal, 53 of whom were available for follow-up. There were two measurement periods: baseline and 12-year follow-up. At both measurement periods, bone mineral content and aBMD of the proximal femur, posterior-anterior lumbar spine, and total body was assessed using dual-energy X-ray absorptiometry (DXA). LBM and FBM were derived from the total-body scans. General health, including current menopausal status, hormone replace therapy use, medication use, and physical activity, was assessed by questionnaires. At the end of the study, 44% of the women were postmenopausal. After controlling for baseline aBMD, current menopausal status, and current hormone replacement therapy, we found that change in LBM was independently associated with change in aBMD of the proximal femur (P = 0.001). The cross-sectional analyses also indicated that LBM was a significant determinant of aBMD of all three DXA-scanned sites at both baseline and follow-up. These novel longitudinal data highlight the important contribution of LBM to the maintenance of proximal femur bone mass at a key time in women's life span, the years surrounding menopause.

Practical differences between luteinizing hormone-releasing hormone agonists in prostate cancer: perspectives across the spectrum of care

PubMed Central

Background: Androgen deprivation therapy (ADT) with luteinizing hormone-releasing hormone (LHRH) agonists is well established for the treatment of men with metastatic prostate cancer. As clear differences in efficacy, safety, or tolerability between the available LHRH agonists are lacking, the healthcare management team needs to look to practical differences between the formulations when selecting therapy for their patients. Moreover, as the economic burden of prostate cancer rises alongside earlier diagnosis and improved survival, the possibility for cost savings by using products with specific features is growing in importance. Methods: A review was conducted to summarize the information on the different LHRH agonist formulations currently available and offer insight into their relative benefits and disadvantages from the perspectives of physicians, a pharmacist, and a nurse. Results: The leuprorelin acetate and goserelin acetate solid implants have the advantage of being ready to use with no requirement for refrigeration, whereas powder and microsphere formulations have to be reconstituted and have specific storage or handling constraints. The single-step administration of solid implants, therefore, has potential to reduce labor time and associated costs. Dosing frequency is another key consideration, as administering the injection provides an opportunity for face-to-face interaction between the patient and healthcare professionals to ensure therapy is optimized and give reassurance to patients. Prostate cancer patients are reported to prefer 3- or 6-monthly dosing, which aligns with the monitoring frequency recommended in European Association of Urology guidelines and has been shown to result in reduced annual costs compared with 1-month formulations. Conclusions: A number of practical differences exist between the different LHRH agonist preparations available, which may impact on clinical practice. It is important for healthcare providers to be aware and carefully consider these differences when selecting treatments for their prostate cancer patients. PMID:29434673

Health literacy and the readability of written information for hormone therapies.

Health education and counseling are important elements of the care provided by clinicians. Counseling efforts may involve helping women to understand their options for symptom management related to various reproductive life transitions. In light of this, the need for information during the menopausal transition is critical for assisting women with their health care decisions. Yet the Institute of Medicine estimates that approximately half the adult population in the United States has difficulty understanding and using health information. The US Food and Drug Administration (FDA) mandates the distribution of written information for estrogen-containing products; however, the readability of information for these pharmaceutical products has not been widely studied. To address this gap, this study examined the readability of written information for FDA-approved prescription menopausal hormone therapies (N = 31). Readability of the written information about hormone therapies from 31 hormone therapy products was assessed using the Flesch Reading Ease and Flesch-Kincaid Grade Level formulas. The reading level ranged from 6.70 to 12.30, with an average grade level of 9.33 (ninth-grade reading level). All but one of the hormone therapy products evaluated in this study exceeded the recommended sixth-grade reading level for written health information. In addition, only 48% of the written information instructions in the study sample (n = 15) included illustrations. Assessment of written information about menopausal hormone therapies showed that the majority of the materials are written at a high reading level. These findings have implications for health literacy and counseling efforts when helping women to understand their options for menopausal symptom management. Midwives, nurses, and other health care providers may need to supplement written information with additional consumer-friendly written information, utilize illustrations, and use verbal instructions more frequently to help support women in evaluating their treatment options. © 2013 by the American College of Nurse-Midwives.

Purpose To evaluate the efficacy of a novel docetaxel derivative of deslorelin, a luteinizing hormone releasing hormone (LHRH) agonist, and its combination in-vivo with RGD peptide conjugated nanoparticles encapsulating an anti-angiogenic, anti-VEGF intraceptor (Flt23k) (RGD-Flt23k-NP) in H1299 lung cancer cells and/or xenografts in athymic nude BALB/c mice. Experimental Design The in-vitro and in-vivo efficacy of the deslorelin-docetaxel conjugate (D-D) was evaluated in H1299 cells and xenografts in athymic nude mice. Co-administration of D-D and RGD-Flt23k-NP was tested in-vivo in mice. Tumor inhibition, apoptosis and VEGF inhibition were estimated in each of the treatment groups. Results The conjugate enhanced in-vitro docetaxel efficacy by 13-fold in H1299 cells compared to docetaxel at 24h, and this effect was inhibited following reduction of LHRH-receptor expression by an antisense oligonucleotide. Combination of the conjugate with the RGD-Flt23k-NP in-vivo resulted in an 82- and 15-fold tumor growth inhibition on day 39 following repeated weekly intravenous injections and a single intratumoral injection, respectively. These effects were significantly greater than individual targeted therapies or docetaxel alone. Similarly, apoptotic indices for the combination therapy were 14 and 10% in the intravenous and intratumoral groups, respectively, and higher than the individual therapies. Combination therapy groups exhibited greater VEGF inhibition in both the intravenous and intratumoral groups. Conclusions Docetaxel efficacy was enhanced by LHRH-receptor targeted deslorelin conjugate and further improved by combination with targeted anti-angiogenic nanoparticle gene therapy. Combination of novel targeted therapeutic approaches described here provides an attractive alternative to the current treatment options for lung cancer therapy. PMID:19920099

Approximately 22,700 Canadian women were expected to be diagnosed with breast cancer in 2012. Despite improvements in screening and adjuvant treatment options, a substantial number of postmenopausal women with hormone receptor positive (hr+) breast cancer will continue to develop metastatic disease during or after adjuvant endocrine therapy. Guidance on the selection of endocrine therapy for patients with hr+ disease that is negative for the human epidermal growth factor receptor 2 (her2-) and that has relapsed or progressed on earlier nonsteroidal aromatase inhibitor (nsai) therapy is of increasing clinical importance. Exemestane, fulvestrant, and tamoxifen are approved therapeutic options in this context. Four phase iii trials involving 2876 patients-efect, sofea, confirm, and bolero-2-have assessed the efficacy of various treatment options in this clinical setting. Data from those trials suggest that standard-dose fulvestrant (250 mg monthly) and exemestane are of comparable efficacy, that doubling the dose of fulvestrant from 250 mg to 500 mg monthly results in a 15% reduction in the risk of progression, and that adding everolimus to exemestane (compared with exemestane alone) results in a 57% reduction in the risk of progression, albeit with increased toxicity. Multiple treatment options are now available to women with hr+ her2- advanced breast cancer recurring or progressing on earlier nsai therapy, although current clinical trial data suggest more robust clinical efficacy with everolimus plus exemestane. Consideration should be given to the patient's age, functional status, and comorbidities during selection of an endocrine therapy, and use of a proactive everolimus safety management strategy is encouraged.

Hypothyroidism is a significant cause of pericardial effusion. However, large pericardial effusions due to hypothyroidism are extremely rare. Hormone replacement therapy is the cornerstone of treatment for hypothyroidism and regular follow-up of patients after initiation of the therapy is indicated. Herein, the case of a 70-year-old woman with a massive pericardial effusion due to Hashimoto's disease is presented. A 70-year-old female from a rural village on the island of Crete, Greece, was admitted to our hospital due to a urinary tract infection. She was under hormone replacement therapy with levothyroxine 100 µg once a day for Hashimoto's disease. Two years previously, the patient had had an episode of pericarditis due to hypothyroidism and had undergone a computed tomography-guided pericardiocentesis. The patient did not have regular follow-up and did not take the hormone replacement therapy properly. On admission, the patient's chest X-ray incidentally showed a possible pericardial effusion. The patient was referred for echocardiography, which revealed a massive pericardial effusion. Beck's triad was absent. Thyroid hormones were consistent with subclinical hypothyroidism: thyroid-stimulating hormone (TSH) 30.25 mIU/mL (normal limits: 0.25-3.43); free thyroxin 4 0.81 ng/dL (normal limits: 0.7-1.94). The patient had a score of 5 on the scale outlined by the European Society of Cardiology (ESC) position statement on triage strategy for cardiac tamponade and, despite the absence of cardiac tamponade, a pericardiocentesis was performed after 48 hours. The patient was treated with 125 µg levothyroxine orally once daily. This was a rare case of an elderly female patient from a rural village with chronic massive pericardial effusion due to subclinical hypothyroidism without cardiac tamponade. Hypothyroidism should be included in the differential diagnosis of pericardial effusion, especially in a case of unexplained pericardial fluid. Initiation of hormone replacement therapy should be personalised in elderly patients. TSH levels >10 mU/L usually require therapy with levothyroxine in order to prevent adverse events. Rural patients usually do not have regular follow-up after the initiation of hormone replacement therapy. Pericardial effusions due to hypothyroidism grow slowly and subclinical hypothyroidism rarely shows signs and symptoms and can be underdiagnosed. The ESC position statement on triage strategy for pericardial diseases is a valuable clinical tool to estimate the necessity for pericardial drainage in such cases.

Metastatic breast cancer (MBC) is unfortunately still considered incurable; treatment aims to prolong progression-free and overall survival, relieve disease symptoms, and maintain quality of life. Treatment can include endocrine therapy, radiotherapy, chemotherapy, bisphosphonates, and/or targeted therapy; which is used depends on the characteristics of the disease [e.g., hormone receptor status, disease site(s), and response to previous treatment] and the patient (age, comorbidity, and personal preferences). For most patients with hormone-receptor-positive tumors, the first choice of treatment is further endocrine therapy, but endocrine resistance is a common problem in advanced disease. Several novel anticancer agents have been developed with the aim of overcoming endocrine resistance, many of which target intracellular signaling pathways implicated in disease progression or resistance. Among these, inhibitors of growth factor receptor tyrosine kinases and of mammalian target of rapamycin have shown the most promise in clinical trials. Chemotherapy is the cornerstone of MBC treatment in most women. Important considerations when choosing chemotherapy include the choice of agents, and whether to use single-agent or combination therapy. Anthracyclines are one of the most active cytotoxic agents currently used for the treatment of breast cancer, and for many women, further anthracycline therapy at progression or relapse would be the preferred option. However, lifetime exposure to anthracyclines is limited by cumulative cardiotoxicity, which often prevents rechallenge in later lines of therapy. Newer anthracycline formulations have been developed with lower cardiotoxicity than the conventional anthracycline doxorubicin, but these agents still impair cardiac function, and have maximum recommended lifetime doses. Recently, the concomitant use of cardioprotective agents, such as dexrazoxane, has emerged as an effective approach to reducing the cardiotoxic effects of anthracyclines, thus permitting retreatment. Bisphosphonates, which are not associated with the acute toxicities of cytotoxic chemotherapy drugs, are the established standard of care for patients with metastatic bone disease, and have greatly improved outcomes over the last decade. The search is ongoing for novel agents that will, hopefully, bring a cure closer to reality.

Modulation of Androgen Receptor Signaling in Hormonal Therapy-Resistant Prostate Cancer Cell Lines

Background Prostate epithelial cells depend on androgens for survival and function. In (early) prostate cancer (PCa) androgens also regulate tumor growth, which is exploited by hormonal therapies in metastatic disease. The aim of the present study was to characterize the androgen receptor (AR) response in hormonal therapy-resistant PC346 cells and identify potential disease markers. Methodology/Principal Findings Human 19K oligoarrays were used to establish the androgen-regulated expression profile of androgen-responsive PC346C cells and its derivative therapy-resistant sublines: PC346DCC (vestigial AR levels), PC346Flu1 (AR overexpression) and PC346Flu2 (T877A AR mutation). In total, 107 transcripts were differentially-expressed in PC346C and derivatives after R1881 or hydroxyflutamide stimulations. The AR-regulated expression profiles reflected the AR modifications of respective therapy-resistant sublines: AR overexpression resulted in stronger and broader transcriptional response to R1881 stimulation, AR down-regulation correlated with deficient response of AR-target genes and the T877A mutation resulted in transcriptional response to both R1881 and hydroxyflutamide. This AR-target signature was linked to multiple publicly available cell line and tumor derived PCa databases, revealing that distinct functional clusters were differentially modulated during PCa progression. Differentiation and secretory functions were up-regulated in primary PCa but repressed in metastasis, whereas proliferation, cytoskeletal remodeling and adhesion were overexpressed in metastasis. Finally, the androgen-regulated genes ENDOD1, MCCC2 and ACSL3 were selected as potential disease markers for RT-PCR quantification in a distinct set of human prostate specimens. ENDOD1 and ACSL3 showed down-regulation in high-grade and metastatic PCa, while MCCC2 was overexpressed in low-grade PCa. Conclusions/Significance AR modifications altered the transcriptional response to (anti)androgens in therapy-resistant cells. Furthermore, selective down-regulation of genes involved in differentiation and up-regulation of genes promoting proliferation and invasion suggest a disturbed balance between the growth and differentiation functions of the AR pathway during PCa progression. These findings may have implications in the current treatment and development of novel therapeutical approaches for metastatic PCa. PMID:21829708

The aim of this study is to explore the associations between hormone treatment variables and depression, and the nature of depression in prostate cancer (PCa) patients by comparing the severity and symptom profile of anxiety and depression in men who were currently receiving hormone therapy (HT) versus those who were not. Self-reports of anxiety and depression on standardized scales of GAD and major depressive disorder (MDD) were collected from 156 PCa patients across two recruitment sites in Australia. Patients who were currently receiving HT were compared with patients not receiving HT for their severity and symptom profiles on GAD and MDD. Participants receiving HT had significantly higher GAD and MDD total scores than patients who were not receiving HT. In addition, the symptom profiles of these two HT subgroups were differentiated by significantly higher scores on the key criteria for GAD and MDD plus fatigue and sleeping difficulties but not the remaining symptoms of GAD and MDD. However, there were no significant differences between HT subgroups for the degree of functional impairment experienced by these symptoms. Although these data confirm the association between HT and anxiety/depression, the range of GAD and MDD symptoms influenced is relatively restricted. Moreover, functional ability does not appear to be impaired by HT. These findings clarify the ways in which HT affects PCa patients and suggests that a simple total scale score for anxiety and depression may not be as helpful in designing treatment as consideration of the symptomatic profiles of PCa patients receiving HT.

We examined whether blood lead levels (BLLs) were associated with reproductive hormone levels in a cross-sectional study using data from the SPECT-China study. We selected 2286 men and 1571 postmenopausal women without hormone replacement therapy. BLLs, blood cadmium, total testosterone (TT), oestradiol (E2), luteinizing hormone (LH), follicle stimulating hormone (FSH) and sex hormone binding globulin(SHBG) levels were measured. The results showed that median values (interquartile range) of BLLs were 44.00 μg/L (29.00-62.30) for men and 41.00 μg/L (27.00-59.81) for postmenopausal women. In linear regression, after adjusting for age, current smoking status, body mass index, systolic blood pressure, diabetes and blood cadmium level, TT (P for trend = 0.001) and SHBG (P for trend < 0.001) levels were still positively associated with BLLs in men. Meanwhile, significant positive associations were found for BLLs with SHBG (P for trend = 0.002), FSH (P for trend = 0.001) and LH (P for trend = 0.026) levels in postmenopausal women. Additionally, the association between BLL and SHBG was modified by dysglycaemia (P for interaction = 0.03) in postmenopausal women. In conclusion, BLLs were associated with reproductive hormone levels in the general population of Chinese men and postmenopausal women, which may have important implications for human health. Concerted efforts to reduce adult lead exposure are warranted.

Investigators extracted data on participants, study design, analysis, follow-up, and results; 2 investigators independently rated study quality by using established criteria. 9 fair-quality trials met the inclusion criteria. The Women's Health Initiative reported most of the results, had 11 years of follow-up, and had data most applicable to postmenopausal women in the United States. It showed that estrogen plus progestin therapy reduced fractures (46 fewer per 10 000 woman-years) and increased invasive breast cancer (8 more per 10 000 woman-years), stroke (9 more per 10 000 woman-years), deep venous thrombosis (12 more per 10 000 woman-years), pulmonary embolism (9 more per 10 000 woman-years), lung cancer death (5 more per 10 000 woman-years), gallbladder disease (20 more per 10 000 woman-years), dementia (22 more per 10 000 woman-years), and urinary incontinence (872 more per 10 000 woman-years). Estrogen-only therapy reduced fractures (56 fewer per 10 000 woman-years), invasive breast cancer (8 fewer per 10 000 woman-years), and death (2 fewer per 10 000 woman-years) and increased stroke (11 more per 10 000 woman-years), deep venous thrombosis (7 more per 10 000 woman-years), gallbladder disease (33 more per 10 000 woman-years), and urinary incontinence (1271 more per 10 000 woman-years). Outcomes did not consistently differ by age or comorbid conditions. Limitations of the trials included low adherence, high attrition, inadequate power to detect risks for some outcomes, and evaluation of few regimens. Estrogen plus progestin and estrogen alone decreased risk for fractures but increased risk for stroke, thromboembolic events, gallbladder disease, and urinary incontinence. Estrogen plus progestin increased risk for breast cancer and probable dementia, whereas estrogen alone decreased risk for breast cancer. Agency for Healthcare Research and Quality.

Emerging Therapies in Metastatic Prostate Cancer.

In the last decade, there have been multiple landmark therapeutic advances for the treatment of metastatic prostate cancer, both in the castration-resistant and hormone-sensitive setting. In this review, we highlight recent progress and ongoing trials for metastatic prostate cancer, including advances in chemotherapy, androgen receptor-directed therapy, targeted therapies, and immunotherapy. Several landmark studies for men with metastatic hormone-sensitive prostate cancer demonstrated improvement in overall survival with the addition of docetaxel chemotherapy or abiraterone acetate to standard androgen deprivation therapy. A single-arm phase 2 study of the PARP inhibitor olaparib demonstrated high response rates and more favorable progression-free and overall survival for men with metastatic castration-resistant prostate cancer and DNA repair defects treated with olaparib compared with men without DNA repair defects. Multiple ongoing clinical trials are investigating novel hormonal therapies and combinations of chemotherapy, targeted small molecules, immunotherapy, and radiopharmaceuticals. Progress continues to be made in the treatment of metastatic prostate cancer, and ongoing clinical trials continue to investigate novel agents and approaches to treatment.

Background More than half of the world’s adults carry Helicobacter pylori. The eradication of H. pylori may affect the regulation of human metabolic hormones. The aim of this study was to evaluate the effect of H. pylori eradication on meal-associated changes in appetite-controlled insulinotropic and digestive hormones, and to assess post-eradication changes in body mass index as part of a currently on-going multicentre ESSAY (Eradication Study in Stable Adults/Youths) study. Methods We enrolled 29 H. pylori-positive young adult (18–30 year-old) volunteer subjects to evaluate the effect of H. pylori eradication on meal-associated changes on eight gastrointestinal hormones, using a multiplex bead assay. Changes in body mass index and anthropometric measurements were recorded, pre- and post-eradication therapy. Results Pre-prandial active amylin, total peptide YY (PYY) and pancreatic polypeptide (PP) levels were significantly elevated 12 months post-eradication compared with baseline (n = 18; Wilcoxon's signed rank test, p<0.05). Four of the post-prandial gut metabolic hormones levels (GLP-1, total PYY, active amylin, PP) were significantly higher 12 months post-eradication compared to baseline (n = 18; p<0.05). Following H. pylori eradication, the BMI and anthropometric values did not significantly change. Conclusions Our study indicates that H. pylori eradication was associated with long-term disturbance in three hormones (active amylin, PP and total PYY) both pre- and post-prandially and one hormone (GLP-1) post-prandially. Longer post-eradication monitoring is needed to investigate the long-term impact of the observed hormonal changes on metabolic homeostasis. PMID:26291794

Ovarian hormones are pivotal for the physiological maintenance of the brain function as well as its response to environmental stimuli. There is mounting evidence attesting the relevance of endogenous ovarian hormones as well as exogenous estradiol and progesterone for emotional and cognitive processing. The present review systematically summarized current knowledge on sex steroid hormonal modulation of neural substrates of emotion and cognition revealed by functional magnetic resonance imaging (fMRI). Twenty-four studies of healthy naturally cycling and combined oral contraceptives (COC) user women, or women undergoing experimental manipulations, during their reproductive age, were included. Furthermore, six studies of premenstrual dysphoric disorder (PMDD), a hormonally based mood disorder, and three of gender dysphoria (GD), which provides an intriguing opportunity to examine the effect of high-dose cross-sex hormone therapy (CSHT) on brain functioning, were included. Globally, low (early follicular and the entire follicular phase for estrogen and progesterone, respectively) and high (COC, CSHT, late follicular and luteal phase for estrogen; COC, mid- and late-luteal phase for progesterone) hormonal milieu diversely affected the response of several brain regions including the amygdala, anterior cingulate cortex, and inferior frontal gyrus, but their functional recruitment across groups and domains was scattered. The constellation of findings provides initial evidence of the influence of sex steroid hormones on cortical and subcortical regions implicated in emotional and cognitive processing. Further well-powered and multimodal neuroimaging studies will be needed to identify the neural mechanism of functional brain alterations induced by sex steroid hormones.

Introduction: The EvaluateTM study (Evaluation of therapy management and patient compliance in postmenopausal hormone receptor-positive breast cancer patients receiving letrozole treatment) is a prospective, non-interventional study for the assessment of therapy management and compliance in the routine care of postmenopausal women with invasive hormone receptor-positive breast cancer receiving letrozole. The parameters for inclusion in the study are presented and discussed here. Material and Methods: Between January 2008 and December 2009 a total of 5045 patients in 310 study centers were recruited to the EvaluateTM study. Inclusion criteria were hormone receptor-positive breast cancer and adjuvant treatment or metastasis. 373 patients were excluded from the analysis for various reasons. Results: A total of 4420 patients receiving adjuvant treatment and 252 patients with metastasis receiving palliative treatment were included in the study. For 4181 patients receiving adjuvant treatment, treatment with the aromatase inhibitor letrozole commenced immediately after surgery (upfront). Two hundred patients had initially received tamoxifen and started aromatase inhibitor treatment with letrozole at 1–5 years after diagnosis (switch), und 39 patients only commenced letrozole treatment 5–10 years after diagnosis (extended endocrine therapy). Patient and tumor characteristics were within expected ranges, as were comorbidities and concurrent medication. Conclusion: The data from the EvaluateTM study will offer a good overview of therapy management in the routine care of postmenopausal women with hormone receptor-positive breast cancer. Planned analyses will look at therapy compliance and patient satisfaction with how information is conveyed and the contents of the conveyed information. PMID:25568468

Although thyroid hormone deficiency, either clinical or subclinical, is an established risk factor for cardiovascular disease, coronary ischemia in a premenopausal woman in her 30s is relatively rare. A 38-year-old woman was referred to our hospital with severe breathlessness and depressed consciousness. Physical examination found facial, abdominal, and pretibial edema; coarse hair, hoarse voice, and dry skin; engorged jugular veins; a distant heart sound; and reduced bilateral entry of air into the chest. Laboratory examinations revealed severe hypothyroidism, hyperlipidemia, and elevated serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125). A computed tomography scan showed massive pleural and pericardial effusions. After 3 months of levothyroxine replacement therapy (initial dose: 12.5 microg/d; maintenance dose: 125 microg/d), all abnormal laboratory values associated with hypothyroidism returned to within normal ranges, with the exception of a transient and paradoxical rise in serum thyroid-stimulating hormone levels. However, 3 weeks after the initiation of therapy, the patient reported intermittent chest pains during the course of therapy, and a coronary artery angiogram revealed diffuse stenosis of all 3 branches. The patient underwent coronary artery bypass grafting, with subsequent improvement in coronary perfusion. Careful cardiovascular evaluation is recommended before the start of thyroid hormone replacement therapy. In addition, care should be taken in the interpretation of serum biomarkers of malignancy (eg, CEA, CA125) in patients with myxedema, as values may be elevated in a hypothyroid state. Long-standing hypothyroidism may be associated with severe coronary atherosclerosis, even in a relatively young, premenopausal woman. The potential adverse cardiovascular effects of thyroid hormone must be considered during replacement therapy, even in relatively young patients.

Thyroid hormone inhibits thyrotropin (TSH) production and thyrotrope growth. Somatostatin has been implicated as a synergistic factor in the inhibition of thyrotrope function. We have previously shown that pharmacological doses of thyroid hormone (levothyroxine [LT4]) inhibit growth of murine TtT-97 thyrotropic tumors in association with upregulation of somatostatin receptor type 5 (sst5) mRNA and somatostatin receptor binding. In the current study, we examined the effect of physiological thyroid hormone replacement alone or in combination with the long-acting somatostatin analogue, Sandostatin LAR, on thyrotropic tumor growth, thyrotropin growth factor-beta (TSH-beta), and sst5 mRNA expression, as well as somatostatin receptor binding sites. Physiological LT4 replacement therapy resulted in tumor shrinkage in association with increased sst5 mRNA levels, reduced TSH-beta mRNA levels and enhanced somatostatin receptor binding. Sandostatin LAR alone had no effect on any parameter measured. However, Sandostatin LAR combined with LT4 synergistically inhibited TSH-beta mRNA production and reduced final tumor weights to a greater degree. In this paradigm, Sandostatin LAR required a euthyroid status to alter thyrotrope parameters. These data suggest an important interaction between the somatostatinergic system and thyroid hormone in the regulation of thyrotrope cell structure and function.

Despite improvements in early detection, surgery and systemic therapy, metastatic breast cancer remains a major cause of death. Luminal type breast cancers expressing hormone estrogen receptor (ER) or progesterone (PR) and without HER2 overexpression are generally sensitive to endocrine therapy, but raise the issue of the occurrence of resistance to treatment, particularly at metastatic stage. A better understanding of hormone resistance may guide the development of new therapeutics. New strategies aim at enhancing and prolonging of endocrine sensitivity, by optimizing existing schemes, or by combining an endocrine therapy with a targeted therapies specific to hormone resistance pathways: ER signaling, PI3K/AKT/mTOR and Cyclin Dependent Kinase (CDK). Key corners of 2014 include confirmation of benefit of high dose fulvestrant, and commercialization of everolimus as the first mTOR inhibitor in this indication. Other strategies are being tested dealing with new endocrine therapies or new molecular targets such as PI3K inhibitors, insulin-like growth factor receptor (IGF-R) and histone deacetylase (HDAC) inhibitors. Coming years may be fruitful and might radically change our way to treat these patients. Copyright © 2015 Société Françise du Cancer. Publié par Elsevier Masson SAS. Tous droits réservés.

Hyperthyroidism.

PubMed

Maji, D

2006-10-01

Hyperthyroidism is a clinical situation where there is excess thyroid hormones in the circulation due to increased synthesis of hormone from a hyperactive thyroid gland. Common causes are Graves' disease, toxic multinodular goitre and toxic solitary nodule. Excess thyroid hormones in the circulation are also found in thyroiditis (hormone leakage) and excess exogenous thyroxine intake. Thyrotoxicosis is the term applied when there is excess thyroid hormone in the circulation due to any cause. Thyrotoxicosis can be easily diagnosed by high serum level of thyroxine (T4) and triiodothyronine (T3) and low serum level of thyroid stimulating hormone (TSH). Hyperthyroidism is confirmed by high isotope (I 131 or Tc99) uptake by the thyroid gland, while in thyroiditis it will be low. Treatment of hyperthyroidism depends on the underlying cause. Antithyroid drugs, 1131 therapy and surgery are the options of treatment of hyperthyroidism. Surgery is the preferred treatment for toxic adenoma and toxic multinodular goitre, while 1131 therapy may be suitable in some cases. Antithyroid drugs and 1131 therapy are mostly preferred for Graves' disease. Beta-adrenergic blockers are used for symptomatic relief in most patients of thyrotoxicosis due to any cause. Other rare causes of hyperthyroidism like, amiodarone induced thyrotoxicosis, choriocarcinoma, thyrotropin secreting pituitary tumour are difficult to diagnose as well as to treat.

Altered sarco(endo)plasmic reticulum calcium adenosine triphosphatase 2a content: Targets for heart failure therapy.

Sarco(endo)plasmic reticulum calcium adenosine triphosphatase is responsible for transporting cytosolic calcium into the sarcoplasmic reticulum and endoplasmic reticulum to maintain calcium homeostasis. Sarco(endo)plasmic reticulum calcium adenosine triphosphatase is the dominant isoform expressed in cardiac tissue, which is regulated by endogenous protein inhibitors, post-translational modifications, hormones as well as microRNAs. Dysfunction of sarco(endo)plasmic reticulum calcium adenosine triphosphatase is associated with heart failure, which makes sarco(endo)plasmic reticulum calcium adenosine triphosphatase a promising target for heart failure therapy. This review summarizes current approaches to ameliorate sarco(endo)plasmic reticulum calcium adenosine triphosphatase function and focuses on phospholamban, an endogenous inhibitor of sarco(endo)plasmic reticulum calcium adenosine triphosphatase, pharmacological tools and gene therapies.

A recently discovered mechanism enabling prostate cancer cells to escape the effects of endocrine therapies consists in the synthesis of C-terminally truncated, constitutively active androgen receptor (AR) splice variants (AR-V). Devoid of a functional C-terminal hormone/ligand binding domain, various AR-Vs are insensitive to therapies targeting the androgen/AR signalling axis. Preliminary studies suggest that AR-V7, the most common AR-V, is a promising predictive tumour marker and a relevant selection marker for the treatment of advanced prostate cancer. This review critically outlines recent advances in AR-V7 diagnostics and presents an overview of current AR-V7 targeted therapies. © Georg Thieme Verlag KG Stuttgart · New York.

What is the current status of ovarian suppression/ablation in women with premenopausal early-stage breast cancer?

PubMed

Higgins, Michaela J; Davidson, Nancy E

2009-01-01

The role of ovarian suppression/ablation (OS/OA) in premenopausal women with hormone receptor-positive breast cancer has been evolving for more than a century. It is clear that OS/OA is an effective adjuvant therapy for these women, but despite numerous studies enrolling thousands of women, many unanswered questions remain. In particular, a major question is whether additional benefit is gained with combination treatment comprising luteinizing hormone-releasing hormone (LH-RH) agonists and tamoxifen over tamoxifen alone. Ongoing trials also are assessing the coupling of aromatase inhibitors (traditionally contraindicated in these patients because of paradoxic stimulation of estrogen production) and LH-RH agonists. Any potential disease-free or overall survival advantage of combination treatment must be balanced against a possible increase in adverse effects and impairment of quality of life. This review focuses on new data on how to incorporate OS/OA into the rational treatment of this challenging patient population.

Recent advances in multidisciplinary management of hepatocellular carcinoma

The incidence of hepatocellular carcinoma (HCC) is increasing, and it is currently the second leading cause of cancer-related death worldwide. Potentially curative treatment options for HCC include resection, transplantation, and percutaneous ablation, whereas palliative treatments include trans-arterial chemoembolization (TACE), radioembolization, and systemic treatments. Due to the diversity of available treatment options and patients’ presentations, a multidisciplinary team should decide clinical management of HCC, according to tumor characteristics and stage of liver disease. Potentially curative treatments are suitable for very-early- and early-stage HCC. However, the vast majority of HCC patients are diagnosed in later stages, where the tumor characteristics or progress of liver disease prevent curative interventions. For patients with intermediate-stage HCC, TACE and radioembolization improve survival and are being evaluated in addition to potentially curative therapies or with systemic targeted therapy. There is currently no effective systemic chemotherapy, immunologic, or hormonal therapy for HCC, and sorafenib is the only approved molecular-targeted treatment for advanced HCC. Other targeted agents are under investigation; trials comparing new agents in combination with sorafenib are ongoing. Combinations of systemic targeted therapies with local treatments are being evaluated for further improvements in HCC patient outcomes. This article provides an updated and comprehensive overview of the current standards and trends in the treatment of HCC. PMID:25866604

Millions of women experience menopause-related hot flashes or flushes that may have a negative effect on their quality of life. Hormone therapy is an effective treatment, however, it may be contraindicated or unacceptable for some women based on previous health complications or an undesirable risk–benefit ratio. Side effects and the unacceptability of hormone therapy have created a need for behavioral interventions to reduce hot flashes. A variety of complex, multimodal behavioral, relaxation-based interventions have been studied with women (n = 88) and showed generally favorable results. However, currently extensive resource commitments reduce the translation of these interventions into standard care. Slow, deep breathing is a common component in most interventions and may be the active ingredient leading to reduced hot flashes. This article describes the content of an audio-based program designed to teach paced breathing to reduce hot flashes. Intervention content was based on skills training theory and music entrainment. The audio intervention provides an efficient way to deliver a breathing intervention that may be beneficial to other clinical populations. PMID:23914283

Background Transgender women have 49 times the odds of human immunodeficiency virus (HIV) infection compared to other groups, yet they are disproportionately underserved by current treatment efforts. Purpose To examine culturally unique barriers and facilitators to engagement and retention in HIV care and strengthen efforts to mitigate health disparities, guided by the Models of Gender Affirmation and Health Care Empowerment. Methods Through 20 interviews and 5 focus groups (n=38), transgender women living with HIV discussed their experiences and life contexts of engagement in and adherence to HIV care and treatment. Results Our participants faced substantial challenges to adhering to HIV care and treatment, including avoidance of healthcare due to stigma and past negative experiences, prioritization of hormone therapy, and concerns about adverse interactions between antiretroviral treatment for HIV and hormone therapy. Receiving culturally competent, transgender-sensitive healthcare was a powerful facilitator of healthcare empowerment. Conclusions Recommendations are offered to inform intervention research and guide providers, emphasizing gender affirming HIV care that integrates transition-related healthcare needs. PMID:24317955

Therapeutic management of premenstrual syndrome.

Freeman, Ellen W

2010-12-01

Premenstrual syndrome (PMS) is among the most common health problems reported by reproductive-age women. Estimates indicate that up to 25% of women may warrant treatment for the distress or impaired functioning associated with the symptoms. The primary focus of this review is the clinical condition of PMS and randomized, placebo-controlled trials of PMS treatment. A literature search in PubMed was conducted for these topics. The most recent reports of specific treatments in controlled treatment studies and all meta-analyses were selected. Reports consistently indicate that serotonergic antidepressants reduce PMS symptoms compared to a placebo. Hormonal treatments are the most widely prescribed medical treatment. Some oral contraceptives and gonadotropin-releasing hormone analogs have demonstrated efficacy, particularly for women who want contraception and PMS symptom control. Numerous non-pharmacologic treatments are utilized, but efficacy is reported only for calcium supplements, Vitex agnus castus (chasteberry), and cognitive-behavioral therapies. Further research to develop new therapies for the 40% of women with PMS who do not respond to the currently available treatments is needed. There are treatments with demonstrated efficacy for PMS, and the majority of women can be helped.

Noonan-like syndrome with loose anagen hair (NS/LAH; OMIM 607721) is caused by a heterozygous c.4A>G mutation in SHOC2. Most cases exhibit both growth hormone deficiency (GHD) and growth hormone insensitivity (GHI) and thus require a high dose of growth hormone (GH) therapy (e.g., 35-40 µg/kg/day). We report on a genetically diagnosed NS/LAH patient manifesting severe short stature (-3.85 SDs) with low serum level of IGF1, 30 ng/ml. The peak levels of GH stimulation tests were within the normal range, and GHI was not observed in the IGF1 generation test. However, with low-dose GH therapy (25 µg/kg/day) for two years, IGF1 level and height were remarkably improved (IGF1: 117 ng/ml, height SDs: -2.20 SDs). Further, catch-up of motor development and improvement of the proportion of extending limbs to trunk were observed (the Developmental Quotient score increased from 68 to 98 points, and the relative sitting height ratio decreased from 0.62 to 0.57). Our results suggest that endocrinological causes for short stature are variable in NS/LAH and that GH therapy should be considered as a possible treatment for delayed development in NS/LAH. © 2015 Wiley Periodicals, Inc.

In vitro studies have demonstrated that thyroid hormones can enhance basal and stimulated growth hormone secretion by cultured pituitary cells. However, both in man and in the rat the effects of high thyroid hormone levels on GH secretion are unclear. The aim of our study was to test the GH response to human GHRH in hyperthyroid patients and to evaluate the effects on GH secretion of short- and long-term pharmacological decrease of circulating thyroid hormones. We examined 10 hyperthyroid patients with recent diagnosis of Graves' disease. Twelve healthy volunteers served as controls. All subjects received a bolus iv injection of GHRH(1-29)NH2, 100 micrograms. Hyperthyroid patients underwent a GHRH test one and three months after starting antithyroid therapy with methimazole, 10 mg/day po. GH levels at 15, 30, 45, 60 min and GH peak after stimulus were significantly lower in hyperthyroid patients than in normal subjects. The GH peak was also delayed in hyperthyroid patients. After one month of methimazole therapy, most of the hyperthyroid patients had thyroid hormone levels in the normal range, but they did not show significant changes in GH levels after GHRH, and the GH peak was again delayed. After three months of therapy with methimazole, the hyperthyroid patients did not show a further significant decrease in serum thyroid hormone levels. However, mean GH levels from 15 to 60 min were significantly increased compared with the control study. The GH peak after GHRH was also earlier than in the pre-treatment study.(ABSTRACT TRUNCATED AT 250 WORDS)

Menopausal hot flashes are considered largely a quality-of-life issue. However, emerging research also links hot flashes to cardiovascular risk. In some investigations, this risk is particularly apparent among women using hormone therapy. The aim of this study was to determine whether a longer history of reported hot flashes over the study period was associated with greater aortic and coronary artery calcification. Interactions with hormone therapy use were examined in an exploratory fashion. Participants included 302 women participating in the Healthy Women Study, a longitudinal study of cardiovascular risk during perimenopause and postmenopause, which was initiated in 1983. Hot flashes (any/none) were assessed when women were 1, 2, 5, and 8 years postmenopausal. Electron beam tomography measures of coronary artery calcification and aortic calcification were completed in 1997-2004. Associations between the number of visits with report of hot flashes, divided by the number of visits attended, and aortic or coronary artery calcification (transformed) were examined in linear regression models. Interactions by hormone therapy use were evaluated. Among women using hormone therapy, a longer history of reported hot flashes was associated with increased aortic calcification, controlling for traditional cardiovascular risk factors (b = 2.87, SE = 1.21, P < 0.05). There were no significant associations between history of hot flashes and coronary artery calcification. Among postmenopausal women using hormone therapy, a longer history of reported hot flashes measured prospectively was associated with increased aortic calcification, controlling for traditional cardiovascular risk factors. Hot flashes may signal adverse cardiovascular changes among certain postmenopausal women.

Proprotein convertase 1/3 (PC1/3) deficiency is a very rare disease characterized by severe intractable diarrhea in the first years of life, followed by obesity and several hormonal deficiencies later. Diabetes mellitus requiring insulin treatment and diabetic ketoacidosis have not been reported in this disorder. We herein present a girl with PC1/3 deficiency who has been followed from birth to 17 years of age. She developed deficiencies of all pituitary hormones over time as well as diabetes mellitus while receiving growth hormone (GH) therapy. She was complicated with diabetic ketoacidosis during dietary management of diabetes mellitus, thus insulin treatment was initiated. Insulin requirement to regulate hyperglycemia was short-lived.

Proprotein convertase 1/3 (PC1/3) deficiency is a very rare disease characterized by severe intractable diarrhea in the first years of life, followed by obesity and several hormonal deficiencies later. Diabetes mellitus requiring insulin treatment and diabetic ketoacidosis have not been reported in this disorder. We herein present a girl with PC1/3 deficiency who has been followed from birth to 17 years of age. She developed deficiencies of all pituitary hormones over time as well as diabetes mellitus while receiving growth hormone (GH) therapy. She was complicated with diabetic ketoacidosis during dietary management of diabetes mellitus, thus insulin treatment was initiated. Insulin requirement to regulate hyperglycemia was short-lived. Repeat oral glucose tolerance test five years later was normal. The findings of this patient show that diabetes mellitus can develop at any time during follow-up of cases with proportein convertase 1/3 deficiency especially under GH therapy.

Androgen hormones and the androgen receptor (AR) pathway are the main targets of anti-hormonal therapies for prostate cancer. However, resistance inevitably develops to treatments aimed at the AR pathway resulting in androgen-independent or hormone-refractory prostate cancer (HRPC). Therefore, there is a significant unmet need for new, non-androgen anti-hormonal strategies for the management of prostate cancer. We demonstrate that a relaxin hormone receptor antagonist, AT-001, an analog of human H2 relaxin, represents a first-in-class anti-hormonal candidate treatment designed to significantly curtail the growth of androgen-independent human prostate tumor xenografts. Chemically synthesized AT-001, administered subcutaneously, suppressed PC3 xenograft growth by up to 60%. AT-001 also synergized with docetaxel, standard first-line chemotherapy for HRPC, to suppress tumor growth by more than 98% in PC3 xenografts via a mechanism involving the downregulation of hypoxia-inducible factor 1 alpha and the hypoxia-induced response. Our data support developing AT-001 for clinical use as an anti-relaxin hormonal therapy for advanced prostate cancer.

[Changes in carbohydrate metabolism and insulin resistance in patients with Prader-Willi Syndrome (PWS) under growth hormone therapy].

Life expectance and life quality have markedly changed in PWS patients within the last 10-15 years. A strict diet, improved physical activity and an additive growth hormone treatment have led to these changes. Growth hormone therapy decreases body fat and improves final height. But growth hormone also antagonizes insulin and therefore increases the diabetic potential. The purpose of our study was to investigate incidence and multiple dependencies of development of impaired carbohydrate metabolism in patients with PWS under growth hormone therapy and to determine suitable parameters for the work-up. 34 patients with genetically approved PWS have been treated with growth hormone for at least 0.5 years. The mean duration of growth hormone treatment was 2.15 years (0.5-4.51). At the start of growth hormone treatment patients were 1.33 to 16.47 years old. The clinical picture and the nutritional situation of children with PWS change age-dependent and can be divided up into three phases. The patients were duty subdivided into three age-groups at the beginning of growth hormone treatment. Group 1: 15 PWS patients, mean age 2.62 years (1.33-3.78). Group 2: 10 PWS patients, mean age 5.54 years (4.08-7.61). Group 3: 9 PWS patients, mean age 11.35 years (8.89-16.47). Data were collected within 0.3-0.38 years before start of treatment and every 6 months throughout the treatment period. Anthropometrical data, fat mass by bioelectric impedance analysis (BIA), fasting insulin, HbA1c, C-peptide, blood fats and the blood sugar profile in oral glucose tolerance tests (OGT/1.75 g glucose/kg body mass) were obtained. Growth hormone therapy was started with an average dose of 0.031 mg/kg body mass in all groups. Insulin resistance was based on Homeostasis Model Assessment-Test (HOMA). No IR or pathological OGT were detected when growth hormone therapy started before the 4th year of life. When therapy started between the 4th and 8th year, PWS patients with normal weight did not develop an IR under GH therapy. 6% developed a glucose tolerance (IGT) disorder and 4% developed an increased fasting glucose (IFG). 5 of 9 PWS patients older than 8 years at therapystart showed a transient disorder of glucose metabolism: 11% of the results obtained in these patients presented an IR with no pathological OGT, 13% showed an IR with IGT, 7% showed an IR with IFG, and 2% showed an IR with transient diabetes. For 4% the IFG persisted with no IR, for 4% the IGT persisted with no IR. These patients differed from younger ones by an increased average BMI, an increase fat body ratio and an increase fasting insulin as well as an already reached puberty. No difference was found in C-peptide, HbA1c or GH dose/kg/body mass. Transient glucose metabolism disorders with no development of manifest insulin resistance are shown by PWS patients with normal weight starting from 4th year under GH therapy. Changes in the glucose metabolism with and with no development of IR appear after start of puberty and weight increase. Changes persisted partially for 18 months. GH therapy was not interrupted for any patient, whereby physical training and dietetic measurements were increased for all patients. HOMA-index and OGT shall be used in parallel to monitor glucose metabolism as both show independently distinctive features. HbA1c and C-peptide are not suitable parameters for monitoring carbohydrate metabolism in PWS patients under GH treatment.

Traditionally, it has been assumed that intellectual development in children with growth hormone deficiency (GHD) is distributed between ranges of a normal population based on the observation that it does not differ substantially from that of children of the same age. Nevertheless, few studies have investigated this assumption. This Spanish Collaborative study was prospectively planned with two main purposes: to study a possible influence of GHD on intelligence quotient (IQ), personality traits and adaptative capacity and to study the evolution of these parameters during substitution therapy with growth hormone (GH). Although the overall intellectual ability of children with GHD is comparable to that of a normal reference population, some areas such the motor-component scale (evaluated by McCarthy test) and performance IQ (evaluated by WISC-R) were below the mean at the beginning of the study, showing significant improvement during therapy. Emotional adjustment (normal at study start) also improved significantly during treatment. Females showed better adjustment capacity before and during GH therapy. Longer studies with an increased number of cases are needed to confirm these effects of GHD and its treatment in children.

Nonlinear system identification for prostate cancer and optimality of intermittent androgen suppression therapy.

These days prostate cancer is one of the most common types of malignant neoplasm in men. Androgen ablation therapy (hormone therapy) has been shown to be effective for advanced prostate cancer. However, continuous hormone therapy often causes recurrence. This results from the progression of androgen-dependent cancer cells to androgen-independent cancer cells during the continuous hormone therapy. One possible method to prevent the progression to the androgen-independent state is intermittent androgen suppression (IAS) therapy, which ceases dosing intermittently. In this paper, we propose two methods to estimate the dynamics of prostate cancer, and investigate the IAS therapy from the viewpoint of optimality. The two methods that we propose for dynamics estimation are a variational Bayesian method for a piecewise affine (PWA) system and a Gaussian process regression method. We apply the proposed methods to real clinical data and compare their predictive performances. Then, using the estimated dynamics of prostate cancer, we observe how prostate cancer behaves for various dosing schedules. It can be seen that the conventional IAS therapy is a way of imposing high cost for dosing while keeping the prostate cancer in a safe state. We would like to dedicate this paper to the memory of Professor Luigi M. Ricciardi. Copyright © 2013 The Authors. Published by Elsevier Inc. All rights reserved.

Screening, prevention, detection, and treatment of cancer therapy-induced bone loss in patients with breast cancer.

Limburg, Connie E

To identify protocols to screen, detect, prevent, and treat cancer therapy-induced bone loss resulting in osteoporosis in patients with breast cancer. Published books and articles. Normal bone remodeling is affected by hormonal stimulation. Breast cancer therapies target hormones that promote cancer cell growth. Chemotherapy regimens and hormone ablation may cause ovarian failure, resulting in decreased hormone levels. A decrease in hormones, in estrogen- and progesterone-positive and -negative patients, introduces an environment for decreased bone remodeling, which may result in thinning bone and osteoporosis. The acceleration of bone loss leading to osteoporosis can result in higher fracture rates among breast cancer survivors. With proper use of screening tools, patient education, and advice about lifestyle changes, all prior to cancer treatment, healthcare professionals may decrease or prevent bone loss in patients with breast cancer. Doing so minimizes healthcare costs and decreases morbidity and mortality rates in breast cancer survivors. As more individuals diagnosed with breast cancer are surviving for extended periods of time, oncology nurses are providing long-term follow-up care. Part of the care should include proper screening and patient education for healthier recovery and prevention of further healthcare complications as a result of cancer treatment.

The human prostate is a gland composed of many types of cells and extracellular components with specific functions. The stromal compartment includes nerve tissue, fibroblasts, lymphocytes, macrophages, endothelial cells, and smooth muscular cells. The epithelial compartment is composed of luminal epithelial cells, basal cells, and a lesser number of neuroendocrine cells, which are transcendental in growth regulation, differentiation, and secretory function. In prostate cancer, neuroendocrine cells replicate especially in high grade and advanced stage, and hormonally treated tumoral cells adopt characteristics that make them resistant to hormonal deprivation. Androgen receptors have a crucial role in tumorigenesis of prostate adenocarcinoma. Deprivation hormone therapy blocks the expression of androgen receptors in the prostatic epithelial cells. Neuroendocrine cells lack androgen receptors; their growth is hormonally independent and that is why deprivation hormonal therapy does not eliminate the neoplasic neuroendocrine cells. In contrast, these types of cells proliferate after therapy and make a paracrine network, stimulating the proliferation of androgen-independent neoplastic cells, which finally lead to tumoral recurrence. In this work we describe the neuroendocrine function in normal tissue and in prostatic adenocarcinoma, including neoplasic proliferation stimulation, invasion, apoptosis resistance, and angiogenesis, and describe some molecular pathways involved in this neuroendocrine differentiation.

First-line investigations to diagnose endometriosis are clinical examination and pelvic ultrasound. Second-line investigations include pelvic examination performed by a referent clinician, transvaginal ultrasound performed by a referent echographist, and pelvic MRI. It is recommended to treat endometriosis when it is symptomatic. First-line hormonal treatments recommended for the management of painful endometriosis are combined with hormonal contraceptives or levonorgestrel 52mg IUD. There is no evidence to recommend systematic preoperative hormonal therapy for the unique purpose of preventing the risk of surgical complications or facilitating surgery. After endometriosis surgery, combined hormonal contraceptives or levonorgestrel SIU 52mg are recommended as first-line therapy in the absence of desire of pregnancy. In case of initial treatment failure, recurrence, or multiple organ involvement by endometriosis, medico-surgical and multidisciplinary discussion is recommended. The laparoscopic approach is recommended for the surgical treatment of endometriosis. HRT may be offered in postmenopausal women operated for endometriosis. In case of infertility related to endometriosis, it is not recommended to prescribe anti-gonadotropic hormone therapy to increase the rate of spontaneous pregnancy, including postoperatively. The possibilities of fertility preservation should be discussed with the patient in case of surgery for ovarian endometrioma. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Combination Therapy with Zoledronic Acid and Parathyroid Hormone Improves Bone Architecture and Strength following a Clinically-Relevant Dose of Stereotactic Radiation Therapy for the Local Treatment of Canine Osteosarcoma in Athymic Rats

Clinical studies using definitive-intent stereotactic radiation therapy (SRT) for the local treatment of canine osteosarcoma (OSA) have shown canine patients achieving similar median survival times as the current standard of care (amputation and adjuvant chemotherapy). Despite this, there remains an unacceptable high risk of pathologic fracture following radiation treatment. Zoledronic acid (ZA) and parathyroid hormone (PTH) are therapeutic candidates for decreasing this fracture risk post-irradiation. Due to differing mechanisms, we hypothesized that the combined treatment with ZA and PTH would significantly improve bone healing more than ZA or PTH treatment alone. Using an orthotopic model of canine osteosarcoma in athymic rats, we evaluated bone healing following clinically-relevant doses of radiation therapy (12 Gy x 3 fractions, 36 Gy total). Groups included 36 Gy SRT only, 36 Gy SRT plus ZA, 36 Gy SRT plus ZA and PTH, 36 Gy SRT plus PTH, and 36 Gy SRT plus localized PTH treatment. Our study showed significant increases in bone volume and increased polar moments of inertia (in the distal femoral metaphysis) 8 weeks after radiation in the combined (ZA/PTH) treatment group as compared to radiation treatment alone. Histomorphometric analysis revealed evidence of active mineralization at the study endpoint as well as successful tumor-cell kill across all treatment groups. This work provides further evidence for the expanding potential indications for ZA and PTH therapy, including post-irradiated bone disease due to osteosarcoma. PMID:27332712

Adrenocorticotropic hormone (ACTH) has shown promising results in glomerular diseases resistant to conventional therapies, but the reported data have solely been from retrospective, observational studies. In this prospective, open-label study (NCT01129284), 15 subjects with resistant glomerular diseases were treated with ACTH gel (80 units subcutaneously twice weekly) for 6 months. Resistant membranous nephropathy (MN), minimal change disease (MCD), and focal segmental glomerulosclerosis (FSGS) were defined as failure to achieve sustained remission of proteinuria off immunosuppressive therapy with at least 2 treatment regimens; resistant IgA nephropathy was defined as >1 g/g urine protein:creatinine ratio despite maximally tolerated RAAS blockade. Remission was defined as stable or improved renal function with ≥50% reduction in proteinuria to <0.5 g/g (complete remission) or 0.5-3.5 g/g (partial remission). The study included 5 subjects with resistant idiopathic MN, 5 subjects with resistant MCD (n = 2)/FSGS (n = 3), and 5 subjects with resistant IgA nephropathy. Two resistant MN subjects achieved partial remission on ACTH therapy, although 3 achieved immunologic remission of disease (PLA(2)R antibody disappeared by 4 months of therapy). One subject with resistant FSGS achieved complete remission on ACTH; one subject with resistant MCD achieved partial remission but relapsed within 4 weeks of stopping ACTH. Two subjects with resistant IgA nephropathy demonstrated >50% reductions in proteinuria while on ACTH, with proteinuria consistently <1 g/g by 6 months. Three of 15 subjects reported significant steroid-like adverse effects with ACTH, including weight gain and hyperglycemia, prompting early termination of therapy without any clinical response. ACTH gel is a promising treatment for resistant glomerular diseases and should be studied further in controlled trials against currently available therapies for resistant disease. Copyright © 2012 S.

The management of patients who relapse after radical radiotherapy is a challenging problem for the multidisciplinary team. This group of men may have been considered ineligible or chosen not to be treated with an initial surgical approach as a result of high-risk features or significant comorbid conditions. It is important not to miss the opportunity for definitive local salvage therapies at this stage, and eligible patients should undergo careful restaging to determine their suitability for these approaches. For those men not suitable for local treatment, androgen deprivation therapy (ADT) remains an option. Literature review of the evidence relating to the management of hormone therapy for radiorecurrent prostate cancer. Results from retrospective studies have shown that not all men with biochemical relapse will experience distant metastasis or a reduction in survival due to prostate cancer progression. Therefore, the timing of ADT commencement remains controversial. However, it would seem appropriate to offer immediate therapy to men with advanced disease or unfavourable prostate-specific antigen (PSA) kinetics at relapse. Patients with more favourable risk factors and PSA kinetics may be considered for watchful waiting and deferred ADT to avoid or delay the associated toxicities. Patients with non-metastatic disease can be given the option of castration-based therapy or an antiandrogen such as bicalutamide which may have potential advantages in maintenance of sexual function, physical capacity and bone mineral density but at the expense of an increase in gynaecomastia and mastalgia. Recent data suggest the burden of toxicity from ADT may be reduced by the use of intermittent hormone therapy without compromising survival in this group of patients with radiorecurrence. Hormone therapy remains an option for men with radiorecurrent prostate cancer.

This meta-analysis is to evaluate the effects and safety of the combination therapy for girls with idiopathic central precocious puberty (ICPP). Electronic databases were searched for randomized controlled trials (RCTs) and clinical controlled trials (CCTs) that adopted gonadotropin-releasing hormone analogue (GnRHa) therapy and GnRHa plus growth hormone (GH) combination therapy to treat ICPP girls. A total of six RCTs (162 patients) and six CCTs (247 patients) were included. Compared to the GnRHa therapy group, the combination therapy group achieved taller final height (mean difference, MD = 2.81 cm, 95 % CI 1.76-3.87, four CCTs; MD = 4.30 cm, 95 % CI 0.59-8.01, one RCT); greater progression of final height compared with target height (MD = 3.92 cm, 95 % CI 3.12-4.73, four CCTs; MD = 4.00 cm, 95 % CI 1.93-6.07, One RCT) and larger height gains (MD = 3.49 cm, 95 % CI 0.97-6.01, four CCTs; MD = 3.88 cm, 95 % CI 0.15-7.61, one RCT). No severe adverse effects of treatment were reported. For ICPP girls, the GnRHa and GH combination therapy had advantages over GnRHa alone on final height and no severe adverse effects were reported. We recommend comprehensive assessment of the individual growth rate, patient compliance, the clinical effects, the height expectations of individual patients and the treatment cost to the family in order to identify the best therapy for individual patients.

The Role of Androgens and Estrogens on Healthy Aging and Longevity

PubMed Central

Dillon, E. Lichar; Urban, Randall J.; Sheffield-Moore, Melinda

2012-01-01

Aging is associated with a loss of sex hormone in both men (andropause) and women (menopause). In men, reductions in testosterone can trigger declines in muscle mass, bone mass, and in physical function. In women, the impact of the loss of sex hormones, such as estradiol, on bone is well elucidated, but evidence is limited on whether the loss of estradiol negatively affects muscle mass and physical function. However, deficiencies in multiple anabolic hormones have been shown to predict health status and longevity in older persons. Thus, consideration should be given as to whether targeted hormone replacement therapies may prove effective at treating clinical conditions, such as age-related sarcopenia, cancer cachexia, and/or acute or chronic illnesses. If initiated carefully in the appropriate clinical population, hormone replacement therapies in men and women may prevent and reverse muscle and bone loss and functional declines and perhaps promote healthy aging and longevity.

We report a 15-year-old boy who had isolated central diabetes insipidus initially diagnosed at age 11 years. A brain magnetic resonance imaging (MRI) was normal at the time. At age 12 years, growth hormone (GH) testing was performed because of a decline in linear growth rate and demonstrated GH deficiency. After a repeat normal brain MRI, GH therapy was begun. Three years later, hormonal testing revealed prepubertal gonadotropins and low testosterone levels, free thyroxine index, and morning cortisol levels. Repeat brain MRI demonstrated a 9-mm enhancing lesion in the region of the pituitary stalk. The pathologic diagnosis was that of a high-grade malignant B-cell lymphoma, suggestive of Burkitt Lymphoma. Growth hormone therapy has not been associated with an increased incidence of lymphoma. This report underscores the need for vigilance in follow-up brain imaging and hormonal evaluation in children with diabetes insipidus, especially those with evolving anterior hormone deficiencies.

Bartter syndrome is a rare autosomal recessive disorder characterized by hypokalemia, salt loss, and metabolic alkalosis. Short stature is one of the clinical manifestations in these children. Although polyuria, polydipsia, hypokalemia, and salt loss may be responsible for growth retardation, the exact pathogenesis of short stature in Bartter syndrome is not known. In this study, we present three children diagnosed as having Bartter syndrome with short stature and growth hormone (GH) deficiency. After recombinant human growth hormone therapy (rhGH), their growth velocities were improved. These results indicate that GH deficiency may contribute to short stature in children with Bartter syndrome, and rhGH therapy would be an excellent adjunctive treatment for short children with this syndrome whose condition is resistant to conventional therapies in terms of growth.

Androgens play a prominent role in the development, maintenance and progression of prostate cancer. The introduction of androgen deprivation therapies into the treatment paradigm for prostate cancer patients has resulted in a wide variety of benefits ranging from a survival advantage for those with clinically localized or locally advanced disease, to improvements in symptom control for patients with advanced disease. Controversies remain, however, surrounding the optimal timing, duration and schedule of these hormonal approaches. Newer hormonal manipulations such as abiraterone acetate have also been investigated and will broaden treatment options for men with prostate cancer. This review highlights the various androgen-directed treatment options available to men with prostate cancer, their specific indications and the evidence supporting each approach, as well as patterns of use of hormonal therapies.

Guidelines recommend that women with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) metastatic breast cancer (mBC) initiate hormonal therapy before chemotherapy. This study compared outcomes of women with mBC who received chemotherapy first vs hormonal therapy. A retrospective cohort study of women with mBC was conducted using a large US commercial health plan database between January 1, 2008-April 30, 2013. Subjects had evidence of a HR+/HER2- tumor sub-type in a cancer registry and use of chemotherapy or hormonal therapy in claims. Subjects were continuously enrolled for ≥6 months after metastasis and assigned to cohorts for receiving chemotherapy only or hormonal therapy only during first-line (CT-1L vs HT-1L). Adjusted incidence rates of clinically significant events were compared using a negative binomial model, and adjusted healthcare costs were compared using a generalized linear model. Three hundred and twenty-four women with HR+/HER2- mBC met the selection criteria; 179 (55%) received CT-1L and 145 (45%) received HT-1L. Mortality rates did not differ between cohorts (unadjusted incidence rate ratio (IRR) = 1.67, 95% CI = 0.82-3.46; adjusted IRR = 0.64, 95% CI = 0.32-1.27). Adjusted average total all-cause healthcare costs were $11 090 for women with CT-1L and $6743 for women with HT-1L (cost ratio =1.64, 95% CI =1.36-1.99). Observed use of first-line chemotherapy (>50%) was higher than expected given the HR + molecular profile of the tumors. Chemotherapy use during first-line did not appear to be associated with a survival benefit, but was associated with significantly higher costs compared with the use of hormonal therapy during first-line; however, this comparison is limited by demographic and baseline characteristic differences between the two cohorts. This study contributes to understanding real-world treatment patterns and the associated clinical and economic outcomes of using chemotherapy vs hormonal therapy as a first-line treatment option for the HR+/HER2- mBC population.

The effects of long-term replacement therapy of adrenal insufficiency (AI) are still a matter of controversy. In fact, the established glucocorticoid replacement regimens do not completely reproduce the endogenous hormonal production and the monitoring of AI treatment may be a challenge for the lack of reliable clinical and biochemical markers. Consequently, several AI patients are frequently exposed to relative glucocorticoid excess potentially leading to develop chronic complications, such as diabetes mellitus, dyslipidemia, hypertension and fragility fractures with consequent impaired QoL and increased mortality risk. This review deals with the pathophysiological and clinical aspects concerning the over-replacement therapy of primary and secondary AI. © 2017 European Society of Endocrinology.

The 2012 Hormone Therapy Position Statement of The North American Menopause Society

PubMed Central

2012-01-01

Objective This position statement aimed to update the evidence-based position statement published by The North American Menopause Society (NAMS) in 2010 regarding recommendations for hormone therapy (HT) for postmenopausal women. This updated position statement further distinguishes the emerging differences in the therapeutic benefit-risk ratio between estrogen therapy (ET) and combined estrogen-progestogen therapy (EPT) at various ages and time intervals since menopause onset. Methods An Advisory Panel of expert clinicians and researchers in the field of women’s health was enlisted to review the 2010 NAMS position statement, evaluate new evidence, and reach consensus on recommendations. The Panel’s recommendations were reviewed and approved by the NAMS Board of Trustees as an official NAMS position statement. Results Current evidence supports the use of HT for perimenopausal and postmenopausal women when the balance of potential benefits and risks is favorable for the individual woman. This position statement reviews the effects of ET and EPT on many aspects of women’s health and recognizes the greater safety profile associated with ET. Conclusions Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms and to prevent osteoporosis in women at high risk of fracture. The more favorable benefit-risk ratio for ET allows more flexibility in extending the duration of use compared with EPT, where the earlier appearance of increased breast cancer risk precludes a recommendation for use beyond 3 to 5 years.

A total of 1450 ambulatory community volunteer participants in the Baltimore Longitudinal Study of Aging examined at the NIA Clinical Research Unit in Baltimore, MD, have undergone longitudinal monitoring of serum thyrotropin (TSH) and thyroid hormone (free thyroxine and free triiodothryonine) levels as well as medication use every one to four years, depending on age, between 2003 and 2014. The prevalence of low TSH was 9.6% for participants on thyroid hormone and 0.8% for nontreated individuals (p < 0.001). New cases occurred at a rate of 17.7/1000 person-years of exposure to thyroid hormone therapy [CI 9-32/1000] and 1.5/1000 person-years in the unexposed population [CI 0.7-2.9/1000]. Women were more likely to be treated and more often overtreated than men were. The adjusted hazard ratio (HR) for thyrotoxicosis between treated and untreated women was 27.5 ([CI 7.2-105.4]; p < 0.001) and 3.8 for men ([CI 1.2-6.3]; p < 0.01). White race/ethnicity and older age were risk factors for thyroid hormone therapy but not overtreatment. Body mass index was not associated with starting therapy (HR = 1.0). Thyroid hormone initiation was highest among women older than 80 years of age (3/100 person-years). For one-third of treated participants with follow-up data, overtreatment persisted at least two years. Iatrogenic thyrotoxicosis accounts for approximately half of both prevalent and incident low TSH events in this community-based cohort, with the highest rates among older women, who are vulnerable to atrial fibrillation and osteoporosis. Physicians should be particularly cautious in treating subclinical hypothyroidism in elderly women in light of recent studies demonstrating no increased risk of cardiovascular morbidity or death for individuals with elevated TSH levels <10 mIU/L.

Transgender women, hormonal therapy and HIV treatment: a comprehensive review of the literature and recommendations for best practices.

Studies have shown that transgender women (TGW) are disproportionately affected by HIV, with an estimated HIV prevalence of 19.1% among TGW worldwide. After receiving a diagnosis, HIV-positive TGW have challenges accessing effective HIV treatment, as demonstrated by lower rates of virologic suppression and higher HIV-related mortality. These adverse HIV outcomes have been attributed to the multiple sociocultural and structural barriers that negatively affect their engagement within the HIV care continuum. Guidelines for feminizing hormonal therapy among TGW recommend combinations of oestrogens and androgen blockers. Pharmacokinetic studies have shown that certain antiretroviral therapy (ART) agents, such as protease inhibitors (PIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and cobicistat, interact with ethinyl estradiol, the key oestrogen component of oral contraceptives (OCPs). The goal of this article is to provide an overview of hormonal regimens used by TGW, to summarize the known drug-drug interactions (DDIs) between feminizing hormonal regimens and ART, and to provide clinical care recommendations. The authors identified English language articles examining DDIs between oestrogen therapy, androgen blockers and ART published between 1995 and 2015 using PubMed, Cumulative Index to Nursing and Allied Health Literature and EBSCOhost. Published articles predominantly addressed interactions between ethinyl estradiol and NNRTIs and PIs. No studies examined interactions between ART and the types and doses of oestrogens found in feminizing regimens. DDIs that may have the potential to result in loss of virologic suppression included ethinyl estradiol and amprenavir, unboosted fosamprenavir and stavudine. No clinically significant DDIs were noted with other anti-retroviral agents or androgen blockers. There are insufficient data to address DDIs between ART and feminizing hormone regimens used by TGW. There is an urgent need for further research in this area, specifically pharmacokinetic studies to study the direction and degree of interactions between oral, injectable and transdermal estradiol and ART. Clinicians need to be vigilant about possible interactions and monitor hormone levels if concerns arise. More research is also needed on the provision of hormone therapy and gender-affirming care on the long-term health outcomes of HIV-positive TGW.

Cranial electrotherapy stimulation for the treatment of depression.

PubMed

Gunther, Mary; Phillips, Kenneth D

2010-11-01

More prevalent in women than men, clinical depression affects approximately 15 million American adults in a given year. Psychopharmaceutical therapy accompanied by psychotherapy and wellness interventions (e.g., nutrition, exercise, counseling) is effective in 80% of diagnosed cases. A lesser known adjunctive therapy is that of cranial electrotherapy stimulation (CES). The major hypothesis for the use of CES in depression is that it may reset the brain to pre-stress homeostasis levels. It is conjectured that the pulsed electrical currents emitted by cranial electrical stimulators affect changes in the limbic system, the reticular activating system, and/or the hypothalamus that result in neurotransmitter secretion and downstream hormone production. While evidence is good for applied research, basic research about the mechanisms of action for CES remains in its infancy. A review of the literature provides an overview of current research findings and implications for clinical mental health practice.

Alopecia and thinning hair are highly prevalent conditions affecting a large proportion of men and women. Diffused hair loss is often more difficult to diagnose in women, mostly due to over-reliance on the assumption of hormonal influences, and it is commonly treated with a multi-therapy approach. Clinical studies have demonstrated the effectiveness of a nutraceutical supplement to provide essential nutrients that aid in stimulating existing hair growth and reducing hair shedding. The supplement Viviscal® contains a proprietary blend of proteins, lipids, and glycosaminoglycans derived from sustainable marine sources. We present here a summary of studies that have examined the safety and efficacy of this nutraceutical; as well as discussions on hair loss and current therapies from a recently convened expert panel in dermatology and plastic surgery.

Patient-derived Hormone-naive Prostate Cancer Xenograft Models Reveal Growth Factor Receptor Bound Protein 10 as an Androgen Receptor-repressed Gene Driving the Development of Castration-resistant Prostate Cancer.

Although androgen deprivation therapy is initially effective in controlling growth of hormone-naive prostate cancers (HNPCs) in patients, currently incurable castration-resistant prostate cancer (CRPC) inevitably develops. To identify CRPC driver genes that may provide new targets to enhance CRPC therapy. Patient-derived xenografts (PDXs) of HNPCs that develop CRPC following host castration were examined for changes in expression of genes at various time points after castration using transcriptome profiling analysis; particular attention was given to pre-CRPC changes in expression indicative of genes acting as potential CRPC drivers. The functionality of a potential CRPC driver was validated via its knockdown in cultured prostate cancer cells; its clinical relevance was established using data from prostate cancer patient databases. Eighty genes were found to be significantly upregulated at the CRPC stage, while seven of them also showed elevated expression prior to CRPC development. Among the latter, growth factor receptor bound protein 10 (GRB10) was the most significantly and consistently upregulated gene. Moreover, elevated GRB10 expression in clinical prostate cancer samples correlated with more aggressive tumor types and poorer patient treatment outcome. GRB10 knockdown markedly reduced prostate cancer cell proliferation and activity of AKT, a well-established CRPC mediator. A positive correlation between AKT activity and GRB10 expression was also found in clinical cohorts. GRB10 acts as a driver of CRPC and sensitizes androgen receptor pathway inhibitors, and hence GRB10 targeting provides a novel therapeutic strategy for the disease. Development of castration-resistant prostate cancer (CRPC) is a major problem in the management of the disease. Using state-of-the-art patient-derived hormone-naive prostate cancer xenograft models, we found and validated the growth factor receptor bound protein 10 gene as a driver of CRPC, indicating that it may be used as a new molecular target to enhance current CRPC therapy.

The Women’s Health Initiative trial found a modestly increased risk of invasive breast cancer with daily 0.625-mg conjugated equine estrogens plus 2.5-mg medroxyprogesterone acetate, with most evidence among women who had previously received postmenopausal hormone therapy. In comparison, observational studies mostly report a larger risk increase. To explain these patterns, the authors examined the effects of this regimen in relation to both prior hormone therapy and time from menopause to first use of postmenopausal hormone therapy (“gap time”) in the Women’s Health Initiative trial and in a corresponding subset of the Women’s Health Initiative observational study. Postmenopausal women with a uterus enrolled at 40 US clinical centers during 1993–1998. The authors found that hazard ratios agreed between the two cohorts at a specified gap time and time from hormone therapy initiation. Combined trial and observational study data support an adverse effect on breast cancer risk. Women who initiate use soon after menopause, and continue for many years, appear to be at particularly high risk. For example, for a woman who starts soon after menopause and adheres to this regimen, estimated hazard ratios are 1.64 (95% confidence interval: 1.00, 2.68) over a 5-year period of use and 2.19 (95% confidence interval: 1.56, 3.08) over a 10-year period of use.

Internal carotid artery (ICA) supraclinoid segment aneurysms extending into the sellar region and leading to pituitary dysfunction are a rare occurrence. To date, long-term follow up of pituitary function 2 years post-treatment has never been reported. Herein, we present a case of pituitary dysfunction due to an unruptured ophthalmic segment internal carotid artery aneurysm and report improved 2-year follow-up results. A 76-year-old male presented with disturbed consciousness due to hyponatremia, which was caused by hypoadrenocorticism resulting from pituitary dysfunction complicated by hypogonadism and hypothyroidism. Computed tomography angiography revealed an intracranial aneurysm of the ophthalmic segment of the right ICA with an intrasellar extension. Thus, digital subtraction angiography and coil embolization were performed, followed by hormone replacement therapy. A 2-year follow-up revealed a partial improvement in the pituitary function, including complete restoration of thyroid-stimulating hormone level and other thyroid hormones levels, and partial restoration of testosterone levels, followed by discontinuation of thyroid hormone replacement therapy. However, the mechanisms of such pituitary dysfunction and the effects of various treatments, including clipping and coiling, on different hormones of pituitary function recovery remain unclear. A long-term follow-up of >2 years may elucidate the pituitary function recovery post-treatment and provide a medication adjustment for hormone replacement therapy.

[Thyroid emergencies : Thyroid storm and myxedema coma].

PubMed

Spitzweg, C; Reincke, M; Gärtner, R

2017-10-01

Thyroid emergencies are rare life-threatening endocrine conditions resulting from either decompensated thyrotoxicosis (thyroid storm) or severe thyroid hormone deficiency (myxedema coma). Both conditions develop out of a long-standing undiagnosed or untreated hyper- or hypothyroidism, respectively, precipitated by an acute stress-associated event, such as infection, trauma, or surgery. Cardinal features of thyroid storm are myasthenia, cardiovascular symptoms, in particular tachycardia, as well as hyperthermia and central nervous system dysfunction. The diagnosis is made based on clinical criteria only as thyroid hormone measurements do not differentiate between thyroid storm and uncomplicated hyperthyroidism. In addition to critical care measures therapy focusses on inhibition of thyroid hormone synthesis and secretion (antithyroid drugs, perchlorate, Lugol's solution, cholestyramine, thyroidectomy) as well as inhibition of thyroid hormone effects in the periphery (β-blocker, glucocorticoids).Cardinal symptoms of myxedema coma are hypothermia, decreased mental status, and hypoventilation with risk of pneumonia and hyponatremia. The diagnosis is also purely based on clinical criteria as measurements of thyroid hormone levels do not differ between uncomplicated severe hypothyroidism and myxedema coma. In addition to substitution of thyroid hormones and glucocorticoids, therapy focusses on critical care measures to treat hypoventilation and hypercapnia, correction of hyponatremia and hypothermia.Survival of both thyroid emergencies can only be optimized by early diagnosis based on clinical criteria and prompt initiation of multimodal therapy including supportive measures and treatment of the precipitating event.

Breast cancer is one of the most common malignancies among women, representing nearly 30% of newly diagnosed cancers every year. Till date, various therapeutic interventions, including surgery, chemotherapy, hormonal therapy, and radiotherapy are available and are known to cause a significant decline in the overall mortality rate. However, therapeutic resistance, recurrence and lack of treatment in metastasis are the major challenges that need to be addressed. Increasing evidence suggests the presence of cancer stem cells (CSCs) in heterogeneous population of breast tumors capable of selfrenewal and differentiation and is considered to be responsible for drug resistance and recurrence. Therefore, compound that can target both differentiated cancer cells, as well as CSCs, may provide a better treatment strategy. Due to safe nature of dietary agents and health products, investigators are introducing them into clinical trials in place of chemotherapeutic agents.This current review focuses on phytochemicals, mainly flavonoids that are in use for breast cancer therapy in preclinical phase. As phytochemicals have several advantages in breast cancer and cancer stem cells, new synthetic series for breast cancer therapy from analogues of most potent natural molecule can be developed via rational drug design approach.

Management of Primary Adrenal Insufficiency: Review of Current Clinical Practice in a Developed and a Developing Country.

Treatment of primary adrenal insufficiency (PAI) requires lifelong hormone replacement with glucocorticoids (GCs) and mineralocorticoids. Impaired quality of life and increased standardized mortality ratio in these patients emphasize the importance of tailoring therapy to individual needs. Role of education is paramount in improving patient compliance and in anticipating and preventing adrenal crises. Although discovery of synthetic GCs was a major breakthrough in treatment of patients with this life-threatening condition, management of PAI continues to be challenging. The obstacles for clinicians appear to vary widely across the globe. While optimization and individualization of therapy after diagnosis of PAI remain the main challenges for clinicians in the developed world, doctors in a developing country face problems at almost every stage from the diagnosis to the treatment and follow-up of these patients; cost of therapy, lack of resources, and funding are the main hindrances. Adherence to therapy and patient education are found to be common issues in most parts of the world. This commentary highlights the challenges from both developed and developing country's perspective in treating PAI; it also provides an update on current management scenario and future treatment options.

Hot flashes are one of the most common and distressing symptoms associated with menopause, occurring in more than 75% of postmenopausal women. They are especially problematic in breast cancer patients since some breast cancer therapies can induce hot flashes. For mild hot flashes, it is proposed that behavioral modifications are the first step in management. Hormonal therapies, including estrogens and progestogens, are the most well known effective agents in relieving hot flashes; however, the safety of these agents is controversial. There is an increasing amount of literature on nonhormonal agents for the treatment of hot flashes. The most promising data regard newer antidepressant agents such as venlafaxine, which reduces hot flashes by about 60%. Gabapentin is another nonhormonal agent that is effective in reducing hot flashes. While many complimentary therapies, including phytoestrogens, black cohosh, and dehydroepiandrosterone, have been explored for the treatment of hot flashes; none can be recommended at this time. Furthermore, there is a lack of strong evidence to support exercise, yoga, or relaxation for the treatment of hot flashes. Paced respirations and hypnosis appear to be promising enough to warrant further investigation. Another promising nonpharmacological therapy, currently under investigation, involves a stellate ganglion block. PMID:21072305

Applying advanced proteomic technologies to prospectively collected specimens from large studies is one means of identifying preclinical changes in plasma proteins that are potentially relevant to the early detection of diseases like breast cancer. We conducted fourteen independent quantitative proteomics experiments comparing pooled plasma samples collected from 420 estrogen receptor positive (ER+) breast cancer patients ≤17 months prior to their diagnosis and matched controls. Based on the over 3.4 million tandem mass spectra collected in the discovery set, 503 proteins were quantified of which 57 differentiated cases from controls with a p-value<0.1. Seven of these proteins, for which quantitative ELISA assays were available, were assessed in an independent validation set. Of these candidates, epidermal growth factor receptor (EGFR) was validated as a predictor of breast cancer risk in an independent set of preclinical plasma samples for women overall [odds ratio (OR)=1.44, p-value=0.0008], and particularly for current users of estrogen plus progestin (E+P) menopausal hormone therapy (OR=2.49, p-value=0.0001). Among current E+P users EGFR's sensitivity for breast cancer risk was 31% with 90% specificity. While EGFR's sensitivity and specificity are insufficient for a clinically useful early detection biomarker, this study suggests that proteins that are elevated preclinically in women who go on to develop breast cancer can be discovered and validated using current proteomic technologies. Further studies are warranted to both examine the role of EGFR and to discover and validate other proteins that could potentially be used for breast cancer early detection. PMID:20959476

Serum sex hormones may be related to the risk of several diseases including osteoporosis, heart disease, and breast and endometrial cancer in postmenopausal women. In the current report, the authors examined the epidemiology of serum sex hormones in 176 healthy, white postmenopausal women (mean age 58 years) recruited from the metropolitan Pittsburgh, Pennsylvania, area. The data were collected during 1982-1983; none of the women were on estrogen replacement therapy. Serum concentrations of estrone, estradiol, testosterone, and androstenedione were measured by a combination of extraction, column chromatography, and radioimmunoassay. Neither age nor time since menopause was a significant predictor of sexmore » hormones. The degree of obesity was a major determinant of estrone and estradiol. The estrone levels of obese women were about 40% higher than the levels of nonobese women. There was a weak relation between obesity and the androgens. Cigarette smokers had significantly higher levels of androstenedione than nonsmokers, with little difference in serum estrogens between smokers and nonsmokers. Both estrone and estradiol levels tended to decline with increasing alcohol consumption. Physical activity was an independent predictor of serum estrone. More active women had lower levels of estrone. There was a positive relation of muscle strength with estrogen levels. The data suggest interesting relations between environmental and lifestyle factors and serum sex hormones. These environmental and lifestyle factors are potentially modifiable and, hence, if associations between sex hormones and disease exist, modification of these factors could affect disease risks.« less

Today, the most pathogenic therapy of GH deficiency is hGH replacement therapy. Replacement hGH therapy a highly effective method of growth correction in children with GH deficiency, but further investigations are necessary for timely detection of disturbances of other organs and systems. The authors reported that hGH therapy supressed thyroid and adrenal functions. Besides, most patients with GH deficiency have multiple defficiency of pituitary hormones (both TSH and ACTH), so hGH therapy can enhances hypothyroidism and hypoadrenalism. In the Department of Pediatric Endocrinology of the Institute of Endocrinology and Metabolism a great experience was accumulated in the treatment of GH deficiency children and in the study of the efficacy and safety of this treatment.

Thyrotropin-producing pituitary tumor is relatively rare. In particular, concurrent cases associated with Graves' disease are extremely rare and only nine cases have been reported so far. We describe a case of a thyrotropin-producing pituitary adenoma concomitant with Graves' disease, which was successfully treated. A 40-year-old Japanese woman presented with mild signs of hyperthyroidism. She had positive anti-thyroid-stimulating hormone receptor antibody, anti-thyroglobulin antibody, and anti-thyroid peroxidase antibody. Her levels of serum thyroid-stimulating hormone, which ranged from low to normal in the presence of high levels of serum free thyroid hormones, were considered to be close to a state of syndrome of inappropriate secretion of thyroid-stimulating hormone. Magnetic resonance imaging showed a macropituitary tumor. The coexistence of thyrotropin-producing pituitary adenoma and Graves' disease was suspected. Initial therapy included anti-thyroid medication, which was immediately discontinued due to worsening symptoms. Subsequently, surgical therapy for the pituitary tumor was conducted, and her levels of free thyroid hormones, including the thyroid-stimulating hormone, became normal. On postoperative examination, her anti-thyroid-stimulating hormone receptor antibody levels decreased, and the anti-thyroglobulin antibody became negative. The coexistence of thyrotropin-producing pituitary adenoma and Graves' disease is rarely reported. The diagnosis of this condition is complicated, and the appropriate treatment strategy has not been clearly established. This case suggests that physicians should consider the coexistence of thyrotropin-producing pituitary adenoma with Graves' disease in cases in which thyroid-stimulating hormone values range from low to normal in the presence of thyrotoxicosis, and the surgical treatment of thyrotropin-producing pituitary adenoma could be the first-line therapy in patients with both thyrotropin-producing pituitary adenoma and Graves' disease.

Previous literature has documented that transgender people may encounter barriers when they use transition-related healthcare services. This study aims to investigate the experiences of transition-related healthcare and the barriers to those services among transgender adults in South Korea. In 2017, we conducted a nationwide cross-sectional survey of 278 transgender adults in South Korea. We assessed the prevalence of transition-related healthcare such as Gender Identity Disorder (GID) diagnosis, hormone therapy, and sex reassignment surgery. To understand the barriers to those procedures, we asked the participants for their reason not to receive each of the three procedures. We also examined their experiences of and reasons for using non-prescribed hormone medication. We found that 91.0% have been diagnosed with GID (N=253/278), 88.0% have received hormone therapy (N=243/276), and 42.4% had any type of sex reassignment surgery (N=115/271). Cost was the most common barrier to transition-related healthcare among the Korean transgender adults. Other common barriers were identified: Negative experiences in healthcare settings, lack of healthcare professionals and facilities, and social stigma against transgender people. Among those who have taken hormone therapy, 25.1% (N=61/243) reported that they had experience of purchasing hormone medication without medical prescription. Our findings suggest that transgender people face barriers to transition-related healthcare in South Korea. These barriers may preclude transgender individuals from safely accessing to transition-related healthcare. Improving access to transition-related healthcare requires institutional interventions including expanding national health insurance coverage on those procedures and providing transition-related training programs for healthcare professionals in South Korea.

Objective Hormone therapy has been shown to reduce markers of vascular inflammation in postmenopausal women. C-reactive protein (CRP), a marker of generalized inflammation, is raised by oral estradiol therapy. It is not known how sex hormone concentrations relate to the markers of inflammation in postmenopausal women taking or not taking hormone therapy. Methods This observational study includes postmenopausal women participating in the Estrogen in the Prevention of Atherosclerosis Trial (EPAT). Multiple measures of serum sex hormone and sex hormone binding globulin (SHBG) levels from 107 postmenopausal women taking oral estradiol therapy (ET) and 109 taking placebo over 2 years were correlated with markers of inflammation over the same time period using generalized estimating equations. Results Levels of soluble intercellular adhesion molecule-1 (sICAM-1) were significantly inversely associated with estrone (p = 0.05), total and free estradiol (p = 0.008 and 0.02, respectively), and SHBG (p = 0.03) only among oral ET users. Serum homocysteine levels were also inversely associated with estrone (p = 0.0001), total and free estradiol (p = 0.0006 and 0.0009, respectively) in ET-treated women only. No such associations were observed among women taking placebo. C-reactive protein (CRP) was positively associated with estrogens and SHBG among women taking oral ET but inversely associated with SHBG among the placebo group. Conclusions The inverse associations of estrogens with sICAM-1, and homocysteine support an anti-inflammatory property of estrogen, which was only observed at pharmacologic levels in postmenopausal women. The positive associations between estrogens and CRP in the ET-treated women can be explained by the first-pass hepatic effect rather than a pro-inflammatory response. PMID:20632462

The interaction between ER and NFκB in resistance to endocrine therapy

PubMed Central

2012-01-01

Endocrine therapy is a commonly used treatment for estrogen receptor (ER)-positive breast cancer. Although endocrine therapy has a favorable outcome in many patients, development of resistance is common. Recent studies have shown that NFκB, a transcription factor regulating a wide variety of cellular processes, might play a role in the development of endocrine resistance. The precise interaction between ER and NFκB and how this contributes to the attenuated responsiveness of ER-positive breast cancer cells to hormonal treatment remains unclear. This review provides an overview of the mechanisms of action for both transcription factors and focuses on the current knowledge explaining how ER and NFκB affect each other's activity and how this cross-talk might contribute to the development of an endocrine resistance phenotype in breast cancer cells.

Heart failure is relatively common in patients with hyperthyroidism, but thyrotoxic cardiomyopathy with poor left ventricular (LV) systolic function is very rare. We experienced a representative case of a patient who presented with severe LV dysfunction related to thyroid storm and needed extracorporeal membrane oxygenation (ECMO) temporally. Thyrotoxic cardiomyopathy. Aggressive antithyroid therapy, including steroid pulse to hyperthyroidism, leads to the dramatic improvement of cardiac function and she was successfully weaned from ECMO. The most outstanding feature of the current case was the rapid decrease of cardiac injury and improvement of cardiac function by strengthening antithyroid therapy, including steroid pulse, without thyroid hormone level normalization. In thyroid storm, various systemic inflammatory reactions have different time courses and among them, the cardiac phenotype emerges in most striking and critical ways.

2007-05-01

Hormone replacement therapy (HRT) containing estrogens is generally used to relieve climacteric symptoms and to prevent osteoporosis and coronary heart disease [1], however, there has been increasing evidence of the HRT as the risk of hormone-dependent neoplasms including breast cancer [2], uterine endometrial cancer [3], ovarian cancer [4], and even lung cancer [5]. Noteworthy is mucinous cyst neoplasms (MCNs) of the pancreas, characterized by mucin-producing columnar epithelium supported by "ovarian-like" mesenchymal stroma, occur mostly in females expressing estrogen receptors [6, 7]. Although several reports regarding the closed relationship between MCNs and pregnancy [8, 9] might imply potential sex hormone-dependency of the MCNs [10], no correlation has been reported. This is the first case report of malignant MCN developing during continuous HRT after hysterectomy.

Postmenopausal hormone therapy may have long-term effects on cognitive function depending on women's age. Postintervention follow-up was conducted with annual cognitive assessments of two randomized controlled clinical trial cohorts, beginning an average of 6-7 years after study medications were terminated: 1,376 women who had enrolled in the Women's Health Initiative when aged 50-54 years and 2,880 who had enrolled when aged 65-79 years. Women had been randomly assigned to 0.625mg/d conjugated equine estrogens (CEE) for those with prior hysterectomy (mean 7.1 years), CEE with 2.5mg/d medroxyprogesterone acetate for those without prior hysterectomy (mean 5.4 years), or matching placebos. Hormone therapy, when prescribed to women aged 50-54 years, had no significant long-term posttreatment effects on cognitive function and on changes in cognitive function. When prescribed to older women, it was associated with long-term mean (SE) relative decrements (standard deviation units) in global cognitive function of 0.081 (0.029), working memory of 0.070 (0.025), and executive function of 0.054 (0.023), all p < .05. These decrements were relatively stable over time. Findings did not vary depending on the hormone therapy regimen, prior use, or years from last menstrual period. Mean intervention effects were small; however, the largest were comparable in magnitude to those seen during the trial's active intervention phase. CEE-based hormone therapy delivered near the time of menopause provides neither cognitive benefit nor detriment. If administered in older women, it results in small decrements in several cognitive domains that remain for many years. © The Author 2016.

Bioidentical Hormones, Menopausal Women, and the Lure of the “Natural” in U.S. Anti-Aging Medicine

Fishman, Jennifer R.; Flatt, Michael A.; Settersten, Richard A.

2015-01-01

In 2002, the Women’s Health Initiative, a large-scale study of the safety of hormone replacement therapy (HRT) for women conducted in the United States, released results suggesting that use of postmenopausal HRT increased women’s risks of stroke and breast cancer. In the years that followed, as rates of HRT prescription fell, another hormonal therapy rose in its wake: bioidentical hormone replacement therapy (BHRT). Anti-aging clinicians, the primary prescribers of BHRT, tout it as a safe and effective alternative to treat menopausal symptoms and, moreover, as a preventative therapy for age-related diseases and ailments. Through in-depth interviews with 31 U.S.-based anti-aging clinicians and 25 female anti-aging patients, we analyze attitudes towards BHRT. We illustrate how these attitudes reveal broader contemporary values, discourses, and discomforts with menopause, aging, and biomedicine. The attraction to and promise of BHRT is rooted in the idea that it is a “natural” therapy. BHRT is given both biomedical and embodied legitimacy by clinicians and patients because of its purported ability to become part of the body’s “natural” processes. The normative assumption that “natural” is inherently “good” not only places BHRT beyond reproach, but transforms its use into a health benefit. The clinical approach of anti-aging providers also plays a role by validating patients’ embodied experiences and offering a “holistic” solution to their symptoms, which anti-aging patients see as a striking contrast to their experiences with conventional biomedical health care. The perceived virtues of BHRT shed light on the rhetoric of anti-aging medicine and a deeply complicated relationship between conventional biomedicine, hormonal technologies, and women’s bodies.

At the start of gender reassignment therapy, persons with a gender identity disorder (GID) may deal with various forms of psychopathology. Until now, a limited number of publications focus on the effect of the different phases of treatment on this comorbidity and other psychosocial factors. The aim of this study was to investigate how gender reassignment therapy affects psychopathology and other psychosocial factors. This is a prospective study that assessed 57 individuals with GID by using the Symptom Checklist-90 (SCL-90) at three different points of time: at presentation, after the start of hormonal treatment, and after sex reassignment surgery (SRS). Questionnaires on psychosocial variables were used to evaluate the evolution between the presentation and the postoperative period. The data were statistically analyzed by using SPSS 19.0, with significance levels set at P < 0.05. The psychopathological parameters include overall psychoneurotic distress, anxiety, agoraphobia, depression, somatization, paranoid ideation/psychoticism, interpersonal sensitivity, hostility, and sleeping problems. The psychosocial parameters consist of relationship, living situation, employment, sexual contacts, social contacts, substance abuse, and suicide attempt. A difference in SCL-90 overall psychoneurotic distress was observed at the different points of assessments (P = 0.003), with the most prominent decrease occurring after the initiation of hormone therapy (P < 0.001). Significant decreases were found in the subscales such as anxiety, depression, interpersonal sensitivity, and hostility. Furthermore, the SCL-90 scores resembled those of a general population after hormone therapy was initiated. Analysis of the psychosocial variables showed no significant differences between pre- and postoperative assessments. A marked reduction in psychopathology occurs during the process of sex reassignment therapy, especially after the initiation of hormone therapy. © 2013 International Society for Sexual Medicine.

Purpose: To determine the influence of maximal androgen blockade (MAB) and non-MAB hormonal therapy with an luteinizing hormone releasing hormone (LHRH) analog on overall survival of prostate cancer patients in the Japan Study Group of Prostate Cancer (J-CaP) registry according to risk, as assessed using the novel J-CAPRA risk instrument. To undertake a multivariate analysis combining J-CAPRA risk score, type of hormonal therapy and comorbidities, in order to assess their impact on overall survival. Methods: The J-CaP database includes men in Japan diagnosed with any stage of prostate cancer between 2001 and 2003 and treated with primary androgen deprivation therapy (PADT), as monotherapy or in combination. A total of 26,272 men were enrolled and of these 19,265 were treated with PADT. This analysis was undertaken using the latest data set (30 April, 2010) including a total of 15,727 patients who received PADT and had follow-up data for periods ranging from 0 to 9.2 years. Results: MAB for prostate cancer patients with intermediate- or high-risk disease has a significant benefit in terms of overall survival compared with LHRH analog monotherapy or surgical castration alone. Better results may be achieved in older (≥75 years) patients. Patient comorbidities are an important factor in determining overall survival, notably in older patients, and should be considered when selecting therapy. Conclusions: Based on large-scale registry data, this report is the first to analyze the outcomes of MAB therapy in patients with prostate cancer at a wide range of disease stages. MAB therapy may provide significant survival benefits in intermediate- and high-risk patients. PMID:24223407

Endocrinology Update: Hypopituitarism.

PubMed

Heidelbaugh, Joel J

2016-12-01

Hypopituitarism is defined as a deficiency of one or more pituitary hormones due to a decline in function of the pituitary gland and/or hypothalamus, which can result in higher risks of morbidity and mortality and decreased quality of life. Although hypopituitarism is a rare condition, it commonly develops after traumatic brain injury and in the setting of functioning and nonfunctioning pituitary adenomas. The diagnosis is based on detailed investigation of symptoms of target endocrine gland function relative to the corresponding pituitary hormone deficiency. The clinical manifestations of hypopituitarism result from the degree of the specific hormone deficiency. A thorough and longitudinal history and physical examination, including visual field testing, are paramount. Management consists of prompt pharmacotherapy, surgery, and/or radiotherapy to restore normal endocrine function and quality of life. In most patients with anterior and posterior pituitary hormone deficiency, corresponding hormone replacement is the mainstay of therapy. The prognosis for patients with hypopituitarism depends on the manner of and age at presentation, degree and severity of hormonal impairment, and response to medical and surgical therapies. Patients with hypopituitarism require lifelong monitoring of serum hormone levels and symptoms of hormone deficiency or excess.

[Pharmacotherapy of solid tumors. New hopes and frustrations].

PubMed

Grünwald, V; Rickmann, M

2014-10-01

Recent years have seen dramatic changes in the biological understanding and treatment of solid tumors. Based on the tumor biology, targeting agents have been developed which directly affect the underlying genetic or immunological changes found in specific tumor entities. Significant increases in survival have delivered the functional proof of the concept of targeted and immunological tumor therapy. The management and adherence of the patient as well as optimized cooperation with clinicians are decisive for the results of therapy and disease control.Several solid tumors are currently under investigation in clinical studies evaluating the (sequential) therapy with targeting and immunologically active agents, e.g. tyrosine kinase and mTOR inhibitors, targeting antibodies, such as bevacizumab, specific antagonists, such as enzalutamide and immunological checkpoint inhibitors via PD(L)1 and/or CTLA 4 antibodies.Currently approved agents have dramatically changed the landscape of treatment options especially for prostate cancer. Such agents include hormone therapy with enzalutamide and abiraterone, radiotherapy with cabazitaxel and xofigo (radium 223), metastatic breast cancer (eribulin and everolimus), renal cell carcinoma (sunitinib, sorafenib, axitinib, everolimus and temsirolimus), non-small cell lung cancer (crizotinib and afatinib), colorectal cancer and gastrointestinal stromal tumor (regorafenib) and melanoma (ipilimumab and vemurafenib). The treatment of rarer tumors, such as pancreatic and hepatocellular cancer and soft tissue sarcoma has entered the stage of targeted therapy with the approval of nanoparticle albumin-bound (nab)-paclitaxel, sorafenib, and eribulin/pazopanib. Current clinical trials are focusing on the best time point and sequence of therapy and also improvement in the management of these promising agents.

The outcomes of three-dimensional conformal radiation therapy (3D-CRT) combined with neoadjuvant hormonal therapy (NAHT) in Japanese patients with locally advanced prostate cancer who initiated salvage hormonal therapy (SHT) at a relatively early phase were evaluated. Between April 1998 and April 2003, 70 Japanese patients with T3N0M0 prostate cancer who received radical 3D-CRT treatment were evaluated. The median age, initial prostate-specific antigen (PSA) level, and duration of NAHT were 73 years old, 26.3 ng/ml, and 4 months, respectively. Seventy grays were given in 35 fractions that were confined to the prostate and seminal vesicles. Adjuvant hormonal therapy was not administered after 3D-CRT in any of the cases. The median follow-up period was 64.9 months. The median PSA value at the time of initiation of SHT was 5.0 ng/ml (range 0.1-21.6 ng/ml). Overall, disease-specific, PSA failure-free (based on the Phoenix definition) and SHT-free survival rates at 5 years were 90.3% (95% CI 86.5-94.0), 96.5% (94.0-98.9), 60.5% (48.2-72.7), and 63.5% (57.2-69.8), respectively. Therefore, two-thirds of the patients were still hormone-free at 5 years. PSA control rates in our series of Japanese patients with stage T3N0M0 prostate cancer treated with the standard dose of 3D-CRT combined with NAHT seemed higher than expected. This approach involving 3D-CRT combined with NAHT with the initiation of SHT at PSA values of around 5 ng/ml may be one option for Japanese patients with locally advanced prostate cancer, although further prospective study is required to confirm the validity.

Emerging biomarkers in breast cancer care.

Napieralski, Rudolf; Brünner, Nils; Mengele, Karin; Schmitt, Manfred

2010-08-01

Currently, decision-making for breast cancer treatment in the clinical setting is mainly based on clinical data, histomorphological features of the tumor tissue and a few cancer biomarkers such as steroid hormone receptor status (estrogen and progesterone receptors) and oncoprotein HER2 status. Although various therapeutic options were introduced into the clinic in recent decades, with the objective of improving surgery, radiotherapy, biochemotherapy and chemotherapy, varying response of individual patients to certain types of therapy and therapy resistance is still a challenge in breast cancer care. Therefore, since breast cancer treatment should be based on individual features of the patient and her tumor, tailored therapy should be an option by integrating cancer biomarkers to define patients at risk and to reliably predict their course of the disease and/or response to cancer therapy. Recently, candidate-marker approaches and genome-wide transcriptomic and epigenetic screening of different breast cancer tissues and bodily fluids resulted in new promising biomarker panels, allowing breast cancer prognosis, prediction of therapy response and monitoring of therapy efficacy. These biomarkers are now subject of validation in prospective clinical trials.

Myocardial performance index (MPI) has been used to assess global ventricular function in different types of cardiac disease. Thyroid hormones influence cardiac performance directly and indirectly by changes in peripheral circulation. The aim of this study was to evaluate the possible effect of central hypothyroidism (CH) on MPI. The study included 28 control subjects and 7 patients with CH without cardiac disease. MPI was defined as the sum of isovolumetric contraction time (ICT) and isovolumetric relaxation time divided by ejection time. Patients were submitted to hormonal therapy with thyroxin and the study was repeated after 35 to 42 days. MPI was significantly higher in patients with CH (0.54 +/- 0.08) than in control subjects (0.40 +/- 0.05) (P =.002). The increase in MPI was caused by the prolongation of ICT without a significant variation of isovolumetric relaxation time and ejection time. After hormonal therapy there was a significant reduction of MPI (0.54 +/- 0.08 vs 0.42 +/- 0.07; P =.028) and ICT. MPI was increased in patients with untreated CH. The increase was related to prolongation of ICT and reverted by hormonal therapy.

Hypopituitarism Presenting as Adrenal Insufficiency and Hypothyroidism in a Patient with Wilson's Disease: a Case Report

PubMed Central

2016-01-01

Wilson's disease typically presents symptoms associated with liver damage or neuropsychiatric disturbances, while endocrinologic abnormalities are rare. We report an unprecedented case of hypopituitarism in a patient with Wilson's disease. A 40-year-old woman presented with depression, general weakness and anorexia. Laboratory tests and imaging studies were compatible with liver cirrhosis due to Wilson's disease. Basal hormone levels and pituitary function tests indicated secondary hypothyroidism and adrenal insufficiency due to hypopituitarism. Brain MRI showed T2 hyperintense signals in both basal ganglia and midbrain but the pituitary imaging was normal. She is currently receiving chelation therapy along with thyroid hormone and steroid replacement. There may be a relationship between Wilson's disease and hypopituitarism. Copper deposition or secondary neuronal damage in the pituitary may be a possible explanation for this theory. PMID:27478349

Hormone therapy (HT) is associated with increased risk of both venous and arterial thrombosis, which are multifactorial in origin. Our objectives were twofold: first, we sought to examine associations between endogenous serum sex hormone levels and biomarkers of thrombosis and/or coagulation in postmenopausal hormone nonusers. Second, we separately studied the associations between serum sex hormone levels and biomarkers of thrombosis and/or coagulation in postmenopausal hormone users considering the fact that pattern of circulating hormones is different in women taking exogenous hormones. We performed a cross-sectional analysis of postmenopausal women enrolled in a large multiethnic community-based cohort study, The Multiethnic Study of Atherosclerosis. We hypothesized that higher levels of estrogen-related sex hormones would be associated with biomarkers of thrombosis, suggesting mechanisms for differences in thrombotic risk from HT. Women (n = 2878) were included if they were postmenopausal and had thrombotic biomarkers (homocysteine, fibrinogen, C-reactive protein [CRP], factor VIII, and d-dimer) and sex hormone levels (total testosterone [T], bioavailable testosterone, sex hormone binding globulin [SHBG], estradiol [E2], and dehydroepiandrosterone [DHEA]) measured. A smaller random sample of 491 women also had von Willebrand factor (vWF), plasminogen activator inhibitor (PAI-1), and tissue factor pathway inhibitor (TFPI) levels measured. We found that elevated levels of estradiol and SHBG in HT users were associated with elevated levels of CRP and lower levels of TFPI, both of which may be related to a prothrombotic milieu in HT users. HT nonusers had far more prothrombotic associations between elevated serum sex hormone levels and thrombotic biomarkers when compared with HT users.

Risks, benefits, and approaches to hormonal blockade in prostate cancer. Highlights from the European Association of Urology Meeting, March 20-24, 2015, Madrid, Spain.

PubMed

Barkin, Jack

2015-06-01

Several abstracts presented at the 2015 European Association of Urology Meeting highlighted new developments in hormone therapy for prostate cancer management. One abstract described how the luteinizing hormone-releasing hormone (LHRH)/gonadotropin-releasing hormone (GnRH) agonist leuprolide, but not the LHRH/GnRH antagonist degarelix, induced plaque instability in a mouse model. A second abstract showed that in patients with a history of severe cardiovascular disease, degarelix was associated with fewer cardiovascular events than treatment with an LHRH agonist. A third abstract showed how primary androgen-deprivation therapy was linked with increased all-cause mortality in a US registry. A fourth abstract showed that in the ANAMEN study, cognitive performance was not significantly affected by 6 months of treatment with GnRH agonists. Last, a fifth abstract showed that low-dose prednisone, with or without abiraterone, was associated with an overall low incidence of corticosteroid-associated adverse events.

Gonadotropin-releasing hormone antagonist in the management of prostate cancer.

PubMed

Debruyne, Frans M J

2004-01-01

Luteinizing hormone-releasing hormone (LHRH) agonist therapy to induce medical castration has become the most common form of hormonal therapy for advanced and metastatic prostate cancer. When treatment is started, LHRH agonists initially stimulate the release of LH, causing a surge in serum testosterone that can precipitate a "flare" phenomenon or worsening of disease, particularly in patients with bone metastatic disease. Gonadotropin-releasing hormone (GnRH) receptor antagonism represents a newer approach to medical castration. Abarelix is a pure GnRH receptor antagonist that is devoid of any LHRH agonist activity. Results from 1 phase II and 3 phase III clinical trials demonstrate that abarelix produces medical castration more quickly and without causing testosterone surge, as compared with LHRH agonists with or without a nonsteroidal antagonist. The safety profile in terms of adverse events is comparable between the 2 types of treatment, but the lack of testosterone surge with abarelix might confer a safety advantage by abolishing the risk of a disease flare.

Diabetes insipidus: celebrating a century of vasopressin therapy.

Qureshi, Sana; Galiveeti, Sneha; Bichet, Daniel G; Roth, Jesse

2014-12-01

Diabetes mellitus, widely known to the ancients for polyuria and glycosuria, budded off diabetes insipidus (DI) about 200 years ago, based on the glucose-free polyuria that characterized a subset of patients. In the late 19th century, clinicians identified the posterior pituitary as the site of pathology, and pharmacologists found multiple bioactivities there. Early in the 20th century, the amelioration of the polyuria with extracts of the posterior pituitary inaugurated a new era in therapy and advanced the hypothesis that DI was due to a hormone deficiency. Decades later, a subset of patients with polyuria unresponsive to therapy were recognized, leading to the distinction between central DI and nephrogenic DI, an early example of a hormone-resistant condition. Recognition that the posterior pituitary had 2 hormones was followed by du Vigneaud's Nobel Prize winning isolation, sequencing, and chemical synthesis of oxytocin and vasopressin. The pure hormones accelerated the development of bioassays and immunoassays that confirmed the hormone deficiency in vasopressin-sensitive DI and abundant levels of hormone in patients with the nephrogenic disorder. With both forms of the disease, acquired and inborn defects were recognized. Emerging concepts of receptors and of genetic analysis led to the recognition of patients with mutations in the genes for 1) arginine vasopressin (AVP), 2) the AVP receptor 2 (AVPR2), and 3) the aquaporin 2 water channel (AQP2). We recount here the multiple skeins of clinical and laboratory research that intersected frequently over the centuries since the first recognition of DI.

Serum estradiol should be monitored not only during the peri-menopausal period but also the post-menopausal period at the time of aromatase inhibitor administration

PubMed Central

2009-01-01

Background Aromatase inhibitor (AI) therapy is being extensively used as postoperative adjuvant therapy in patients with hormone receptor-positive postmenopausal breast cancer. On the other hand, it has been reported that ovarian function was restored when AI was administered to patients who had undergone chemical menopause with chemotherapy or tamoxifen. However, there have been no reports of comprehensive monitoring of estradiol (E2) in breast cancer patients with ordinary menopause who were being administered AI. Patients and Methods Beginning in March 2008, regular monitoring of the serum levels of E2, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) was performed for 66 postmenopausal breast cancer patients who had been started on AI therapy. For this study, we chose anastrozole as the AI. The assays of those hormones were outsourced to a commercial clinical laboratory. Results In 4 of the 66 patients the serum E2 level was decreased at 3 months but had then increased at 6 months, while in 2 other patients E2 was decreased at both 3 and 6 months but had increased at 9 months. Conclusion The results indicate that, in some breast cancer patients with ordinary menopause, E2 rebounds following AI therapy. In the future, E2 monitoring should be performed for a larger number of patients being administered AI therapy. Trial registration Our trial registration number is 19-11-1211. PMID:19909552

Urine metabonomic profiling of a female adolescent with PIT-1 mutation before and during growth hormone therapy: insights into the metabolic effects of growth hormone.

Growth hormone (GH) is a protein hormone with important roles in growth and metabolism. The objective of this study was to investigate the metabolism of a human subject with severe GH deficiency (GHD) due to a PIT-1 gene mutation and the metabolic effects of GH therapy using Nuclear Magnetic Resonance (NMR)-based metabonomics. NMR-based metabonomics is a platform that allows the metabolic profile of biological fluids such as urine to be recorded, and any alterations in the profile modulated by GH can potentially be detected. Urine samples were collected from a female subject with severe GHD before, during and after GH therapy, and from healthy age- and sex-matched controls and analysed with NMR-based metabonomics. The samples were collected at a hospital and the study was performed at a research facility. We studied a 17 year old female adolescent with severe GHD secondary to PIT-1 gene mutation who had reached final adult height and who had ceased GH therapy for over 3 years. The subject was subsequently followed for 5 years with and without GH therapy. Twelve healthy age-matched female subjects acted as control subjects. The GH-deficient subject re-commenced GH therapy at a dose of 1 mg/day to normalise serum IGF-1 levels. Urine metabolic profiles were recorded using NMR spectroscopy and analysed with multivariate statistics to distinguish the profiles at different time points and identify significant metabolites affected by GH therapy. NMR-based metabonomics revealed that the metabolic profile of the GH-deficient subject altered with GH therapy and that her profile was different from healthy controls before, and during withdrawal of GH therapy. This study illustrates the potential use of NMR-based metabonomics for monitoring the effects of GH therapy on metabolism by profiling the urine of GH-deficient subjects. Further controlled studies in larger numbers of GH-deficient subjects are required to determine the clinical benefits of NMR-based metabonomics in subjects receiving GH therapy.

Parathyroid hormone and its analogues--molecular mechanisms of action and efficacy in osteoporosis therapy.

PubMed

Misiorowski, Waldemar

2011-01-01

Most medical agents currently applied in osteoporosis therapy act by inhibiting bone resorption and reducing bone remodelling, i.e. they inhibit the process of bone mass loss by suppressing bone resorption processes. These drugs provide an ideal therapeutic option to prevent osteoporosis progression. They however have a rather limited usefulness when the disease has already reached its advanced stages with distinctive bone architecture lesions. The fracture risk reduction rate, achieved in the course of anti-resorptive therapy, is insufficient for patients with severe osteoporosis to stop the downward spiral of their quality of life (QoL) with a simultaneously increasing threat of premature death. The activity of the N-terminal fragment of 1-34 human parathormone (teriparatide - 1-34 rhPTH), a parathyroid hormone (PTH) analogue obtained via genetic engineering , is expressed by increased bone metabolism, while promoting new bone tissue formation by stimulating the activity of osteoblasts more than that of osteoclasts. The anabolic activity of PTH includes both its direct effect on the osteoblast cell line, and its indirect actions exerted via its regulatory effects on selected growth factors, e.g. IGF-1 or sclerostin. However, the molecular mechanisms responsible for the actual anabolic effects of PTH remain mostly still unclear. Clinical studies have demonstrated that therapeutic protocols with the application of PTH analogues provide an effective protection against all osteoporotic fracture types in post-menopausal women and in elderly men with advanced osteoporosis. Particular hopes are pinned on the possibility of applying PTH in the therapy of post-steroid osteoporosis, mainly to suppress bone formation, the most important pathological process in this regard. The relatively short therapy period with a PTH analogue (24 months) should then be replaced and continued by anti-resorptive treatment.

Most medical agents currently applied in osteoporosis therapy act by inhibiting bone resorption and reducing bone remodelling, i.e. they inhibit the process of bone mass loss by suppressing bone resorption processes. These drugs provide an ideal therapeutic option to prevent osteoporosis progression. They however have a rather limited usefulness when the disease has already reached its advanced stages with distinctive bone architecture lesions. The fracture risk reduction rate, achieved in the course of anti-resorptive therapy, is insufficient for patients with severe osteoporosis to stop the downward spiral of their quality of life (QoL) with a simultaneously increasing threat of premature death.

Anovulatory cycles and endometriosis are the main causes of female infertility. The most frequently anovulatory cycles are related to polycystic ovary syndrome (PCOS) commonly associated with obesity and hormonal disturbances in the course of obesity. Recently published studies revealed that infertility affects about one in six couples during their lifetime and is more frequent in obese. Obesity is also associated with male infertility related to erectile dysfunction, hormonal disturbances and lower semen quality. Any of these above mentioned disorder is the important risk factor of psychological disturbances and poor quality of life among women and men in the reproductive age. On the other hand the mood disorders may exacerbate the hormonal disturbances and worsen the effectiveness of infertility management. Infertility, its therapy with accompanying psychological disturbances may also significantly affect the partners relationships. The review summarize the results described in the current literature on the association between obesity and infertility and psychological disturbances as well as their impact on quality of life and sexual functioning in women and men. Moreover, the impact of infertility and psychological disturbances on partners relationships is discussed. PMID:22844280

Growth hormone therapy for Prader–willi syndrome: challenges and solutions

Grugni, Graziano; Sartorio, Alessandro; Crinò, Antonino

2016-01-01

Prader–Willi syndrome (PWS) is characterized by a dysregulation of growth hormone (GH)/insulin-like growth factor I axis, as the consequence of a complex hypothalamic involvement. PWS’ clinical picture seems to resemble the classic non-PWS GH deficiency (GHD), including short stature, excessive body fat, decreased muscle mass, and impaired quality of life. GH therapy is able to ameliorate the phenotypic appearance of the syndrome, as well as to improve body composition, physical strength, and cognitive level. In this regard, however, some pathophysiologic and clinical questions still remain, representing a challenge to give the most appropriate care to PWS patients. Data about the prevalence of GHD in PWS children are not unequivocal, ranging from 40% to 100%. In this context, to establish whether the presence (or not) of GHD may have a different effect on clinical course during GH therapy may be helpful. In addition, the comparison of GH effects in PWS children diagnosed as small for gestational age with those obtained in subjects born appropriate for gestational age is of potential interest for future trials. Emerging information seems to demonstrate the maintenance of beneficial effects of GH therapy in PWS subjects after adolescent years. Thus, GH retesting after achievement of final height should be taken into consideration for all PWS patients. However, it is noteworthy that GH administration exerts positive effects both in PWS adults with and without GHD. Another critical issue is to clarify whether the genotype–phenotype correlations may be relevant to specific outcome measures related to GH therapy. Moreover, progress of our understanding of the role of GH replacement and concomitant therapies on bone characteristics of PWS is required. Finally, a long-term surveillance of benefits and risks of GH therapy is strongly recommended for PWS population, since most of the current studies are uncontrolled and of short duration.

The International Society for the Study of Women's Sexual Health process of care (POC) for management of hypoactive sexual desire disorder (HSDD) algorithm was developed to provide evidence-based guidelines for diagnosis and treatment of HSDD in women by health care professionals. Affecting 10% of adult females, HSDD is associated with negative emotional and psychological states and medical conditions including depression. The algorithm was developed using a modified Delphi method to reach consensus among the 17 international panelists representing multiple disciplines. The POC starts with the health care professional asking about sexual concerns, focusing on issues related to low sexual desire/interest. Diagnosis includes distinguishing between generalized acquired HSDD and other forms of low sexual interest. Biopsychosocial assessment of potentially modifiable factors facilitates initiation of treatment with education, modification of potentially modifiable factors, and, if needed, additional therapeutic intervention: sex therapy, central nervous system agents, and hormonal therapy, guided in part by menopausal status. Sex therapy includes behavior therapy, cognitive behavior therapy, and mindfulness. The only central nervous system agent currently approved by the US Food and Drug Administration (FDA) for HSDD is flibanserin in premenopausal women; use of flibanserin in postmenopausal women with HSDD is supported by data but is not FDA approved. Hormonal therapy includes off-label use of testosterone in postmenopausal women with HSDD, which is supported by data but not FDA approved. The POC incorporates monitoring the progress of therapy. In conclusion, the International Society for the Study of Women's Sexual Health POC for the management of women with HSDD provides a rational, evidence-based guideline for health care professionals to manage patients with appropriate assessments and individualized treatments.

Reporter sex and newspaper coverage of the adverse health effects of hormone therapy.

Nelson, David E; Signorielli, Nancy

2007-01-01

Women have used hormone therapy (HT) to relieve menopausal symptoms for decades. Major studies published in JAMA in July 2002 demonstrated adverse health effects from hormone therapy, and the National Institutes of Health halted the Women's Health Initiative clinical trial several years early. We conducted a content analysis of 10 U.S. newspapers in July and August 2002 to examine the role of reporter sex on news coverage on HT. We found substantial sex differences in reporting about HT. Female reporters were much more likely than male reporters to include a self-help frame (66.7% vs. 30.8%, p = 0.002). Female reporters were also much more likely to use women in the public as sources in HT-related articles (33.9% vs. 10.0%, p = 0.039). Reporter sex may play a role in the selection and content of health news articles.

Endocrine therapy toxicity: management options.

Henry, N Lynn

2014-01-01

Treatment with adjuvant endocrine therapy, including tamoxifen and the aromatase inhibitors, has resulted in notable improvements in disease-free and overall survival for patients with hormone receptor-positive breast cancer. Despite their proven benefit, however, adherence to and persistence with the medications is poor in part because of bothersome side effects that can negatively affect quality of life. Retrospective analyses have identified possible predictors of development of toxicity. Reports have also suggested that development of toxicity may be a biomarker of better response to therapy. In addition, there has been considerable research investment into the management of these side effects, which may lead to improved adherence and persistence with therapy. However, although notable advances have been made, much more remains to be done to provide patients with truly personalized therapy for hormone receptor-positive breast cancer.

The prospect of gene therapy for prostate cancer: update on theory and status.

Koeneman, K S; Hsieh, J T

2001-09-01

Molecularly based novel therapeutic agents are needed to address the problem of locally recurrent, or metastatic, advanced hormone-refractory prostate cancer. Recent basic science advances in mechanisms of gene expression, vector delivery, and targeting have rendered clinically relevant gene therapy to the prostatic fossa and distant sites feasible in the near future. Current research and clinical investigative efforts involving methods for more effective vector delivery and targeting, with enhanced gene expression to selected (specific) sites, are reviewed. These areas of research involve tissue-specific promoters, transgene exploration, vector design and delivery, and selective vector targeting. The 'vectorology' involved mainly addresses selective tissue homing with ligands, mechanisms of innate immune system evasion for durable transgene expression, and the possibility of repeat administration.

This study was undertaken to identify growth hormone (GH) responsive proteins and protein expression patterns by short-term recombinant human growth hormone (rhGH) therapy in patients with idiopathic short stature (ISS) using proteomic analysis. Seventeen children (14 males and three females) with ISS were included. They were treated with rhGH at a dose of 0.31 ± 0.078 mg/kg/week for 3 months. Immunodepletion of six highly-abundant serum proteins followed by 2D DIGE analysis, and subsequent MALDI TOF MS, were employed to generate a panel of proteins differentially expressed after short-term rhGH therapy and verify the differences in serum levels of specific proteins by rhGH therapy. Fourteen spots were differentially expressed after rhGH treatment. Among them, apo E and apo L-1 expression were consistently enhanced, whereas serum amyloid A was reduced after rhGH therapy. The differential expressions of these proteins were subsequently verified by Western blot analysis using sera of the before and after rhGH treatment. This study suggests that rhGH therapy influences lipoprotein metabolism and enhances apo L-1 protein expression in ISS patients. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Weight gain and body fat increase the risk of cardiometabolic disease. Cross-sex hormone therapy in transgender persons leads to changes in body weight and body composition, but it is unclear to what extent. We performed a meta-analysis to investigate the changes in body weight, body fat and lean body mass during cross-sex hormone therapy in transgender persons. We searched the PubMed database for eligible studies until November 2015. Ten studies reporting changes in body weight, body fat or lean mass in hormone naive transgender persons were included, examining 171 male-to-female and 354 female-to-male transgender people. Pooled effect estimates in the male-to-female group were +1.8 kg (95% CI: 0.2;3.4) for body weight, +3.0 kg (2.0;3.9) for body fat and -2.4 kg (-2.8; -2.1) for lean body mass. In the female-to-male group, body weight changed with +1.7 kg (0.7;2.7), body fat with -2.6 kg (-3.9; -1.4) and lean body mass with +3.9 kg (3.2;4.5). Cross-sex hormone therapy increases body weight in both sexes. In the male-to-female group, a gain in body fat and a decline in lean body mass are observed, while the opposite effects are seen in the female-to-male group. Possibly, these changes increase the risk of cardiometabolic disease in the male-to-female group. © 2016 Blackwell Verlag GmbH.

Metabolic abnormalities in pituitary adenoma patients: a novel therapeutic target and prognostic factor

PubMed Central

Zheng, Xin; Li, Song; Zhang, Wei-hua; Yang, Hui

2015-01-01

Metabolic abnormalities are common in cancers, and targeting metabolism is emerging as a novel therapeutic approach to cancer management. Pituitary adenoma (PA) is a type of benign tumor. Impairment of tumor cells’ metabolism in PA seems not to be as apparent as that of other malignant tumor cells; however, aberrant hormone secretion is conspicuous in most PAs. Hormones have direct impacts on systemic metabolism, which in turn, may affect the progression of PA. Nowadays, conventional therapeutic strategies for PA do not include modalities of adjusting whole-body metabolism, which is most likely due to the current consideration of the aberrant whole-body metabolism of PA patients as a passive associated symptom and not involved in PA progression. Because systemic metabolic abnormalities are presented by 22.3%–52.5% PA patients and are closely correlated with disease progression and prognosis, we propose that assessment of metabolic status should be emphasized during the treatment of PA and that control of metabolic abnormalities should be added into the current therapies for PA.

Growth hormone deficiency in a patient with mitochondrial disease.

2015-09-01

Mitochondrial respiratory chain (MRC) disorders, defined as primary diseases of the oxidative phosphorylation system, are a protean group of metabolic disorders, difficult to diagnose and classify. The diagnosis is complex and requires the integration of information obtained by clinical, laboratory testing, imaging and muscle biopsy. They may be associated with endocrine disorders, including hypothyroidism, diabetes mellitus, hyperinsulinemia and growth hormone (GH) deficiency. We describe a case of five years old male with polymalformative syndrome with a systemic involvement. At 6 months of age, he was sent to metabolic consultation because of facial dysmorphy and short stature. During the investigation it was diagnosed at the boy a growth hormone deficiency and because of his multisystemic involvement, muscle biopsy was carried out and showed reduced activity of complex II (38%) of the mitochondrial respiratory chain. Currently, the boy is under GH therapy with growth in the 5th percentile and coenzime Q10. Mitochondrial biology is one of the fastest growing areas in genetics and medicine. Disturbances in mitochondrial metabolism are now known to play a role not only in rare childhood diseases, but also in many common diseases of aging. In mitochondrial disorders, short stature is a common symptom, but its underlying lesion, growth hormone deficiency, is rarely investigated.

Growth hormone (GH) is essential not only for normal growth during childhood, but also for the acquisition of bone mass and muscle strength in both sexes. This process is completed after the achievement of adult height in the phase of transition from adolescence to adulthood. Adolescents with childhood onset GH deficiency (GHD) show reduction of bone mineral density, decrease in lean body mass, increase in fat mass, and deterioration of the lipid profile. For this reason, continuation of GH replacement therapy in the transition age is recommended in all patients with a confirmed diagnosis of GHD. To confirm the diagnosis of GHD, GH treatment should be discontinued for at least 1 month after the attainment of adult height, and the patient should be re-evaluated for GH secretion. Current guidelines indicate that retesting is not required for those with a transcription factor mutation, more than 3 pituitary hormone deficits, or isolated GHD associated with an identified mutation. The key predictors of persistent GHD are its severity, the presence of additional pituitary hormone deficits, low insulin-like growth factor I (IGF-I) concentration, and the presence of structural hypothalamic-pituitary abnormalities Treatment should be initiated with a low dose (0.2-0.5 mg/day s.c.) and then adjusted according to IGF-I concentrations. © 2018 S.

Retinoblastoma (RB) is the most common intraocular cancer in children worldwide. Current treatments mainly involve combinations of chemotherapies, cryotherapies, and laser-based therapies. Severe or late-stage disease may require enucleation or lead to fatality. Recently, RB has been shown to arise from cone precursor cells, which have high MDM2 levels to suppress p53-mediated apoptosis. This finding leads to the hypothesis that restoring apoptosis mechanisms in RBs could specifically kill the cancer cells without affecting other retinal cells. We have previously reported involvement of an extrapituitary signaling pathway of the growth hormone-releasing hormone (GHRH) in the retina. Here we show that the GHRH receptor (GHRH-R) is highly expressed in RB cells but not in other retinal cells. We induced specific apoptosis with two different GHRH-R antagonists, MIA-602 and MIA-690. Importantly, these GHRH-R antagonists do not trigger apoptosis in other retinal cells such as retinal pigmented epithelial cells. We delineated the gene expression profiles regulated by GHRH-R antagonists and found that cell proliferation genes and apoptotic genes are down- and up-regulated, respectively. Our results reveal the involvement of GHRH-R in survival and proliferation of RB and demonstrate that GHRH-R antagonists can specifically kill the RB cells.

Current Diagnosis and Management of Erectile Dysfunction

PubMed Central

Pastuszak, Alexander W.

2015-01-01

Erectile dysfunction (ED) affects a growing number of men in the USA and abroad, with significant impacts on sexual function and overall quality of life. The risk factors for ED are numerous and include a strong link to cardiovascular disease, such that men with ED should be screened for cardiovascular disease. The evaluation of men presenting with ED includes a comprehensive history and physical exam to aid in the identification of comorbidities as well as laboratory testing to evaluate hormone and lipid levels and sugar metabolism. Adjunct studies are also available, though their utility is often limited to specific subtypes of ED. Once the etiology of ED is established, treatment can be initiated using appropriate medical therapies, including phosphodiesterase type 5 (PDE5) inhibitors, and transurethral or intracavernosal therapies, with surgical intervention via revascularization or penile prosthesis placement in men demonstrating a lack of response to medical therapy. In all cases of ED, a psychogenic component is present and referral for psychological intervention with or without medical therapy should be considered. PMID:25878565

An overview of early drug development for endometriosis.

PubMed

Leone Roberti Maggiore, Umberto; Ferrero, Simone

2016-01-01

Endometriosis is an estrogen-dependent chronic disease of women of fertile age requiring chronic therapy. Although available drugs have good efficacy and safety profiles, some patients experience partial or no improvement of pain with conventional treatment and recurrence of symptoms after discontinuation of the therapies. For these reasons, many new compounds are currently under investigation for the treatment of endometriosis. This review offers the reader a complete and updated overview on emerging therapies for the treatment of endometriosis. The authors describe, in detail, the laboratory and clinical studies on these therapies and highlight the potential advantages and limitations associated with the administration of these new agents. Gonadotropin-releasing hormone antagonists are the most intriguing emerging agents for the treatment of patients with endometriosis. It should be noted that while there are a number of drugs under investigation, a large majority of these new compounds have only been investigated in laboratory studies with more extensive research required to better elucidate their efficacy and safety profiles.

Thyroid Hormone Therapy and Risk of Thyrotoxicosis in Community-Resident Older Adults: Findings from the Baltimore Longitudinal Study of Aging

PubMed Central

McGready, John; Oxman, Rachael; Chia, Chee W.; Ladenson, Paul W.; Simonsick, Eleanor M.

2015-01-01

Background: Both endogenous and exogenous thyrotoxicosis has been associated with atrial fibrillation and low bone mineral density. Therefore, this study investigated the risk factors associated with prevalent and incident thyrotoxicosis and the initiation of thyroid hormone therapy in a healthy, aging cohort. Methods: A total of 1450 ambulatory community volunteer participants in the Baltimore Longitudinal Study of Aging examined at the NIA Clinical Research Unit in Baltimore, MD, have undergone longitudinal monitoring of serum thyrotropin (TSH) and thyroid hormone (free thyroxine and free triiodothryonine) levels as well as medication use every one to four years, depending on age, between 2003 and 2014. Results: The prevalence of low TSH was 9.6% for participants on thyroid hormone and 0.8% for nontreated individuals (p < 0.001). New cases occurred at a rate of 17.7/1000 person-years of exposure to thyroid hormone therapy [CI 9–32/1000] and 1.5/1000 person-years in the unexposed population [CI 0.7–2.9/1000]. Women were more likely to be treated and more often overtreated than men were. The adjusted hazard ratio (HR) for thyrotoxicosis between treated and untreated women was 27.5 ([CI 7.2–105.4]; p < 0.001) and 3.8 for men ([CI 1.2–6.3]; p < 0.01). White race/ethnicity and older age were risk factors for thyroid hormone therapy but not overtreatment. Body mass index was not associated with starting therapy (HR = 1.0). Thyroid hormone initiation was highest among women older than 80 years of age (3/100 person-years). For one-third of treated participants with follow-up data, overtreatment persisted at least two years. Conclusions: Iatrogenic thyrotoxicosis accounts for approximately half of both prevalent and incident low TSH events in this community-based cohort, with the highest rates among older women, who are vulnerable to atrial fibrillation and osteoporosis. Physicians should be particularly cautious in treating subclinical hypothyroidism in elderly women in light of recent studies demonstrating no increased risk of cardiovascular morbidity or death for individuals with elevated TSH levels <10 mIU/L.

[Advances in the treatment of acromegaly].

PubMed

Krysiak, Robert; Okopień, Bogusław; Marek, Bogdan

2008-01-01

Acromegaly is a slow developing chronic debilitating disease caused by a growth hormone (GH)-producing pituitary adenoma. The clinical consequences of acromegaly result both from excess GH secretion and from mass effect of the pituitary tumour. The disease is associated with increased morbidity and mortality compared to normal population. Currently available therapies for acromegaly are transsphenoidal surgery, radiotherapy and medical therapy. The last includes dopamine agonists, slow release formulation of somatostatin analogues and pegvisomant, a GH-receptor antagonist. All these forms of treatment attempt to control the disease by reducing GH secretion from the tumour and inhibiting the growth of adenoma. The decision concerning the choice of therapy should depend on age, the severity of acromegaly and the presence of its complications and should also consider the dangers associated with each treatment. This review paper summarizes the contemporary treatment of acromegaly with special emphasis on their established benefits and risks.

Data regarding costs of prostate cancer treatment are scarce. This study investigates how initial treatment choice affects short-term and long-term costs. This retrospective, longitudinal cohort study followed prostate-cancer cases diagnosed in 2000 for 5 years using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Men age≥66 years, in Medicare fee for service, diagnosed with clinically localized prostate cancer in 2000 while residing in a SEER region, were matched to noncancer controls using age, sex, race, region, comorbidity, and survival. On the basis of treatment received during the first 9 months postdiagnosis, patients were assigned to watchful waiting, radiation, hormonal therapy, hormonal+radiation, and surgery (may have received other treatments). Incremental costs for prostate cancer were the difference in costs for prostate cancer cases versus matched controls. Costs were divided into initial treatment (months -1 to 12), long-term (each 12 months thereafter), and total (months -1 to 60). Sensitivity analyses excluded the last 12 months of life. A total of 13,769 prostate-cancer cases were matched to 13,769 noncancer controls. Watchful waiting had the lowest initial treatment ($4270) and 5-year total costs ($9130). Initial treatment costs were highest for hormonal+radiation ($17,474) and surgery ($15,197). At $26,896, 5-year total costs were highest for hormonal therapy only followed by hormonal+radiation ($25,097) and surgery ($19,214). After excluding the last 12 months of life, total costs were highest for hormonal+radiation ($23,488) and hormonal therapy ($23,199). Patterns of costs vary widely based on initial treatment. These data can inform patients and clinicians considering treatment options and policy makers interested in patterns of costs. Copyright © 2010 American Cancer Society.

Preclinical studies have demonstrated that conditioned fear extinction is impaired in females with low endogenous levels of the sex hormone estradiol, due to menstrual fluctuations or hormonal contraceptive use. As fear extinction is a laboratory model of exposure therapy for anxiety and trauma disorders, here we assessed the hypothesis that treatment outcomes may be diminished when exposure therapy occurs during periods of low estradiol. 90 women with spider phobia (60 cycling and 30 using hormonal contraceptives) underwent a one-session exposure treatment for spider phobia, following which, serum estradiol levels were assessed. A median split in estradiol level was used to divide cycling participants into two groups; lower and higher estradiol. Behavioral avoidance and self-reported fear of spiders were measured pre-treatment, post-treatment, and at a 12 week follow-up assessment. Women using hormonal contraceptives exhibited a significantly slower rate of improvement across treatment, greater behavioral avoidance at post-treatment and follow-up, and fewer self-initiated post-treatment exposure tasks, relative to both groups of cycling women, who did not differ. No group differences in self-reported fear were evident. Correlational analyses revealed that across the whole sample, lower estradiol levels were associated with slower rates of improvement across treatment, and greater self-reported fear and behavioral avoidance at post-treatment, but not follow-up. These results provide the first evidence of an association between endogenous estradiol, hormonal contraceptive use, and exposure therapy outcomes in spider phobic women. Hormonal profile may partly account for variability in responsiveness to psychological treatments for anxiety and trauma disorders in women. Copyright © 2018 Elsevier Ltd. All rights reserved.

A combined case of macroprolactinoma, growth hormone excess and Graves' disease.

Thyrotoxicosis due to Graves disease is a relatively common endocrine disorder. The occurrence of a prolactinoma with co-secretion of growth hormone (GH) is on the other hand, rare. We report the rare co-existence of Graves' disease in a patient with macroprolactinoma and GH hypersecretion and describe the successful response to medical therapy with dopamine agonist and antithyroid therapy. We hypothesize that hyperprolactinaemia played a role in promoting autoimmune thyroid disease in our patient and that treatment of hyperprolactinaemia may have been important in suppressing autoimmune disease activity in Graves' disease. This case also reflects on the close and complex interactions between thyroid hormones, prolactin (PRL), GH and testosterone (T).

Neutropenia secondary to antithyroid drug (ATD) therapy in Graves' disease (GD) is well recognized. However, the effect of hyperthyroidism, prior to and after ATD therapy, on neutrophil counts in patients with GD is unclear. To study the prevalence of neutropenia in newly diagnosed untreated GD and the effect of ATD on the neutrophil count. Prospective study from August 2010 to December 2014. Endocrinology outpatient clinic in a single centre. Consecutive patients (n = 206) with newly diagnosed GD. ATD therapy. Prevalence and factors predicting neutropenia (<2 × 10 9 /l) and change in neutrophil counts following ATD. At diagnosis, 29 (14·1%) of GD individuals had neutropenia. Non-Caucasians [odds ratio (95% CI) of 4·06 (1·14-14·45), P = 0·03] and patients with higher serum thyroid hormone levels [OR 1·07 (1·02-1·13), P = 0·002 for serum FT3] were the only independent predictors of neutropenia. All patients with neutropenia had normalized blood neutrophil levels after achieving euthyroidism with ATD therapy. In patients in whom data were available posteuthyroidism (n = 149), change in neutrophil count after achieving euthyroidism was independently related to reduction in thyroid hormone levels (P < 0·01). GD is associated with neutropenia in one in seven patients at diagnosis, especially in non-Caucasians and those with higher serum thyroid hormone levels. Neutrophil counts increase with treatment with ATD and are related to reduction in thyroid hormone concentrations. It is therefore important to check neutrophil levels in newly diagnosed patients with GD prior to commencing ATD therapy as otherwise low levels may incorrectly be attributed to ATD therapy. © 2016 John Wiley & Sons Ltd.

Familial combined pituitary hormone deficiency is a rare endocrine disorder. We describe growth patterns of four children (3 females and 1 male) from two families with combined pituitary hormone deficiency. These children received growth hormone at ages ranging from 14.5 years to 19 years. While all the female siblings reached their target height, the male sibling was much shorter than mid parental height. The reasons for sexual dimorphism in growth patterns in these children are unclear.

To compare the changes induced by oral versus transdermal estrogen therapy on the total and free serum concentrations of testosterone (T), thyroxine (T4), and cortisol (C) and the concentrations of their serum binding globulins sex hormone-binding globulin, thyroxine-binding globulin, and cortisol-binding globulin in naturally menopausal women. Randomized, open-label, crossover. Interventions included a 6-week withdrawal from previous hormone therapy (baseline), followed in randomized order by 12 weeks of oral conjugated equine estrogens (CEE) (0.625 mg/d) and 12 weeks of transdermal estradiol (TD E2) (0.05 mg/d), with oral micronized progesterone (100 mg/d) given continuously during both transdermal estrogen therapy regimens. Twenty-seven women were enrolled in the study, and 25 completed both treatment periods. The mean(SD) percentage changes from baseline of sex hormone-binding globulin, total T, and free T with oral CEE were +132.1% (74.5%), +16.4% (43.8%), and -32.7% (25.9%), respectively, versus +12.0% (25.1%), +1.2% (43.7%), and +1.0% (45.0%) with TD E2. The mean (SD) percentage changes of thyroxine-binding globulin, total T4, and free T4 with oral CEE were +39.9% (20.1%), +28.4% (29.2%), and -10.4% (22.3%), respectively, versus +0.4% (11.1%), -0.7% (16.5%), and +0.2% (26.6%) with TD E2. The mean (SD) percentage changes of cortisol-binding globulin, total C, and free C with oral CEE were +18.0% (19.5%), +29.2% (46.3%), and +50.4% (126.5%), respectively, versus -2.2% (11.3%), -6.7% (30.8%), and +1.8% (77.1%) with TD E2. Concentrations of all hormones and binding globulins were significantly different (P < or = 0.003) during administration of oral versus transdermal estrogen therapy, except for free T4 and free C. Compared with oral CEE, TD E2 exerts minimal effects on the total and free concentrations of T, T4, and C and their binding proteins.

A plethora of in vitro and in vivo studies have supported the neuroprotective role of estrogens and their impact on the neurotransmitter systems implicated in cognition. Recent hormonal replacement therapy trials in non-demented post-menopausal women suggest a temporary positive effect (notably on verbal memory), and four meta-analyses converge to suggest a possible protective effect in relation to Alzheimer’s disease (reducing risk by 29 to 44%). However, data from the only large randomized controlled trial published to date, the Women’s Health Initiative Memory Study, did not confirm these observations and have even suggested an increase in dementia risk for women using hormonal replacement therapy compared to controls. Apart from methodological differences, one key short-coming of this trial has probably been the focus on late-onset (postmenopausal) hormonal changes, i.e. at a time when the neurodegenerative process has already begun and without taking into account individual lifetime exposure to hormone variability. Multifactorial models based on an exhaustive view of all hormonal events throughout the reproductive life (rather than on a specific exposure to a given steroid) together with other risk factors (notably genetic risk factors related to estrogen receptor polymorphisms) should be explored to clarify the role of hormonal risk factors, or protective factors for cognitive dysfunction and dementia.

Postmenopausal changes in the hormonal milieu in women with or without hormone therapy are hypothesized to be the pathway for a number of menopause-associated modifications in physiology and disease risk. Physical activity may modify these changes in women's hormone profiles. The crucial yet complex relationship between physical activity and physiologic and pharmacologic sex hormone levels in postmenopausal women has not been investigated sufficiently. Using structured recall, physical activity was assessed longitudinally during a period of 2 years in 194 postmenopausal women (90 randomized to 1 mg 17β-estradiol treatment daily and 104 randomized to placebo) in the Estrogen in the Prevention of Atherosclerosis Trial. The levels of physical activity were correlated with the serum sex hormone and the serum hormone-binding globulin levels in each treatment group. Among the placebo-treated women, total energy expenditure was positively associated with sex hormone-binding globulin (SHBG; P < 0.001) and inversely associated with testosterones (total, bioavailable, or free) and androstenedione (P < 0.001 for all), as well as with estradiol (P = 0.02). In estradiol-treated women, estradiol levels were inversely associated with total energy expenditure (P = 0.002) and weekly hours spent in moderate or more vigorous physical activity (P = 0.001). Physical activity is associated with lower serum levels of estradiol in both hormone therapy-treated and untreated women. In placebo-treated women only, physical activity is associated with reduced androgen levels and elevated SHBG levels.

To survey women who stopped hormone replacement therapy (HRT) after 2002, including those who later restarted. A questionnaire on the UK-based menopause website www.menopausematters.co.uk evaluating how women are influenced by HRT advice. Main outcome measures Answers to questions regarding stopping/restarting HRT in response to the advice in the early 2000s and advice given today. A total of 1100 responses were obtained. Of those who made the decision to stop HRT themselves, 56.4% (n = 425/754) said that they were influenced by the media. In those who would potentially most benefit from HRT, 72.8% (n = 220/302) stopped without medical advice. Overall, women aged under 50 years were significantly more likely to stop HRT themselves than women over 50 (P < 0.001). In women in whom symptoms returned, 37.5% (n = 362/966) said these affected their ability to work, 45.1% (n = 436) had problems with decision-making, 53.6% (n = 518) admitted to relationships being negatively affected and 29.2% (n = 286) said that symptoms affected their social relationships. Overall 46.5% of women (n = 485/1044) would not have stopped HRT given the current understanding of risk. Compared with women over 50, significantly more women under the age of 50 said that they would not have previously stopped their HRT based on their current understanding of risk (P < 0.001). The negative impact of published research and its reporting from the early 2000s are being mitigated by current press coverage. Media reports appear to influence the younger woman more than the older woman. Health professionals and media must learn the lessons from the past.

A 54-year-old female patient is admitted for evaluation of her thyroid function after two cycles of ipilimumab therapy. The decision for the anti-cytotoxic-T-lymphocyte-antigen-4-therapy (anti-CTLA-4) was made two months earlier because of malignant melanoma with pulmonary metastases. The patient was euthyroid before initiation of treatment and without known thyroid disease. The laboratory reveals thyrotoxicosis with elevated anti-thyroid peroxidase and anti-thyroglobulin antibody levels. The anti-thyroid stimulating hormone receptor antibody levels are within the normal range. Thyroid ultrasound shows a normal-sized, inhomogenous, hypoechogenic thyroid gland, consistent with autoimmune thyroiditis. Diagnosis of hyperthyroidism due to ipilimumab-induced autoimmune thyroiditis is made. The patient does not receive any thyroid-specific medication, with regular control of the thyroid hormone levels. When the patient becomes euthyroid, the ipilimumab therapy is continued. Three weeks later, the patient develops hypothyroidism and a supplementation with L-thyroxine is initiated. An anti-CTLA-4 therapy may cause thyroid dysfunction. Therefore, before initiation and in the course of the treatment, regular controls of the thyroid hormone levels are required. © Georg Thieme Verlag KG Stuttgart · New York.

In hyperthyroidism, the primary objective of therapy is to reduce secretion of thyroid hormone, which can be accomplished in various ways. The stimulus to hypersecretion can be removed in some causes of hyperthyroidism; in others, hormone synthesis and release can be inhibited by drugs such as thioamides, adrenergic blocking agents, or possibly lithium or glucocorticoids. Radioactive iodine is indicated for primary therapy of uncomplicated hyperthyroidism due to Graves' disease in persons over 30 years of age (myxedema may be a complication) and for treatment of autonomous thyroid adenoma in patients who are not suitable candidates for surgery. Surgical ablation ismore » preferred for some causes of hyperthyroidism but may induce postoperative hypothyroidism. Hypothyroidism due to thyroid failure usually presents few therapeutic difficulties and can be managed simply by long-term hormone replacement. Before hormone replacement is prescribed for secondary or tertiary hypothyroidism, the other pituitary functions should be assessed.« less

MANAGEMENT OF ENDOCRINE DISEASE: Pitfalls on the replacement therapy for primary and central hypothyroidism in adults.

Hypothyroidism is one of the most common hormone deficiencies in adults. Most of the cases, particularly those of overt hypothyroidism, are easily diagnosed and managed, with excellent outcomes if treated adequately. However, minor alterations of thyroid function determine nonspecific manifestations. Primary hypothyroidism due to chronic autoimmune thyroiditis is largely the most common cause of thyroid hormone deficiency. Central hypothyroidism is a rare and heterogeneous disorder characterized by decreased thyroid hormone secretion by an otherwise normal thyroid gland, due to lack of TSH. The standard treatment of primary and central hypothyroidism is hormone replacement therapy with levothyroxine sodium (LT4). Treatment guidelines of hypothyroidism recommend monotherapy with LT4 due to its efficacy, long-term experience, favorable side effect profile, ease of administration, good intestinal absorption, long serum half-life and low cost. Despite being easily treatable with a daily dose of LT4, many patients remain hypothyroid due to malabsorption syndromes, autoimmune gastritis, pancreatic and liver disorders, drug interactions, polymorphisms in DIO2 (iodothyronine deiodinase 2), high fiber diet, and more frequently, non-compliance to LT4 therapy. Compliance to levothyroxine treatment in hypothyroidism is compromised by daily and fasting schedule. Many adult patients remain hypothyroid due to all the above mentioned and many attempts to improve levothyroxine therapy compliance and absorption have been made. © 2018 European Society of Endocrinology.

To assess the effects of postmenopausal hormone replacement therapy (HRT) on intraocular pressure (IOP). This was a cross-sectional controlled study, including 107 women aged 60 to 80 years receiving HRT and 107 controls who have never received HRT. All subjects underwent IOP assessment and funduscopic photography for cup-to-disc (C/D) ratios, and completed questionnaires regarding personal and family history of glaucoma, hormone replacement therapy, lifetime estrogen and progesterone exposure, and cardiovascular risk factors. Main Outcome Measures included IOP, prevalence of increased IOP, and C/D ratios. The groups did not differ in mean IOP (15.3 versus 15.3 mm Hg), mean vertical (0.18 versus 0.21) and horizontal (0.17 versus 0.14) C/D ratios, and in prevalence of increased IOP (15% versus 14%), C/D ratio (7% versus 7%), or glaucoma (9% versus 11%). A personal history of ischemic heart disease was the only risk factor associated with increased IOP (O.R. = 4.63, P = 0.003). Lifetime estrogen and progesterone exposure, including pregnancies, deliveries, menstruation years, and the use of oral contraceptives did not significantly affect the risk for increased IOP. Hormone replacement therapy and lifetime estrogen and progesterone exposure do not seem to affect IOP or the risk for increased IOP. A personal history of ischemic heart disease may be associated with a higher risk for this disorder.

Resistance to thyroid hormone β (RTH β ) due to homozygous THRB defects is exceptionally rare, with only five kindreds reported worldwide. Cardiac dysfunction, which can be life-threatening, is recognized in the disorder. Here we describe the clinical, metabolic, ophthalmic, and cardiac findings in a 9-year-old boy harboring a biallelic THRB mutation (R243Q), along with biochemical, physiologic, and cardiac responses to carbimazole and triiodothyroacetic acid (TRIAC) therapy. The patient exhibits recognized features (goiter, nonsuppressed thyroid-stimulating hormone levels, upper respiratory tract infections, hyperactivity, low body mass index) of heterozygous RTH β , with additional characteristics (dysmorphic facies, winging of scapulae) and more markedly elevated thyroid hormone levels, associated with the homozygous form of the disorder. Notably, an older sibling with similar clinical features and probable homozygous RTH β had died of cardiac failure at age 13 years. Features of early dilated cardiomyopathy in our patient prompted combination treatment with carbimazole and TRIAC. Careful titration of therapy limited elevation in TSH levels and associated increase in thyroid volume. Subsequently, sustained reduction in thyroid hormones with normal TSH levels was reflected in lower basal metabolic rate, gain of lean body mass, and improved growth and cardiac function. A combination of antithyroid drug and TRIAC therapy may prevent thyrotoxic cardiomyopathy and its decompensation in homozygous or even heterozygous RTH β in which life-threatening hyperthyroid features predominate.

Resistance to thyroid hormone beta (RTHβ) is a rare and usually dominantly inherited syndrome caused by mutations of the thyroid hormone receptor β gene (THRB). In severe cases, it is rarely challenging to control manifestations using daily therapeutic replacement of thyroid hormone. The present case study concerns an 8-year-old Japanese girl with a severe phenotype of RTH (TSH, fT3, and fT4 were 34.0 mU/L, >25.0 pg/mL and, >8.0 ng/dL, respectively), caused by a novel heterozygous frameshift mutation in exon 10 of the thyroid hormone receptor beta gene (THRB), c.1347-1357 del actcttccccc : p.E449DfsX11. RTH was detected at the neonatal screening program. At 4 years of age, the patient continued to suffer from mental retardation, hyperactivity, insomnia, and reduced resting energy expenditure (REE), despite daily thyroxine (L-T4) therapy. Every-other-day high-dose liothyronine (L-T3) therapy improved her symptoms and increased her REE, without thyrotoxicosis. In a case of severe RTH, every-other-day L-T3 administration enhanced REE and psychomotor development, without promoting symptoms of thyrotoxicosis. Every-other-day L-T3 administration may be an effective strategy for the treatment of severe RTH.

Gc protein-derived macrophage-activating factor (GcMAF) occurs naturally in the human body. It has various functions, such as macrophage activation and antitumor activities. Recently, immunotherapy has become an attractive new strategy in the treatment of cancer. GcMAF-based immunotherapy can be combined with many other therapies. Sonodynamic therapy (SDT) using low-intensity ultrasound is a novel therapeutic modality. Ultrasound has been demonstrated to activate a number of sonosensitive agents allowing for the possibility of non-invasive targeted treatment for both superficial and deep-seated tumors. The current case study demonstrates that GcMAF and SDT can be used in combination with conventional therapies in patients with metastatic cancer, especially where treatment options are limited due to factors such as toxicity. This case study also suggests a new concept of cancer treatment using local destruction of cancer tissue, in this case conducted with SDT, to be used in combination with GcMAF immunotherapy as a systemic treatment.

Chronic application of third generation progestagens as contraceptives or hormone replacement therapy (HRT) could influence the serum lipid profile, and consequently the bile and gallstone composition. The aim of this study was to determine components of serum, bile and gallstones in women of reproductive age or postmenopausal women using hormonal third generation for at least two years. We enrolled 101 Caucasian women with cholelithiasis. The study included 45 women of reproductive age and 56 postmenopausal women who were divided into subgroups receiving or not exogenous female hormones. In patients we determined serum levels of 17β-estradiol, triglycerides, HDL and LDL cholesterol as well as composition of gallstones and bile. The postmenopausal women showed a significant reduction in the concentration of bile acids in serum while the application of HRT caused an increase in their contents. Serum total and LDL cholesterol in postmenopausal women was higher than in women without hormonal contraception and postmenopausal patients with HRT. Moreover, women taking the exogenous hormones showed a reduced content of calcium ions in both serum, bile and gallstones. Our observations confirm that the chronic use of oral contraceptives and hormone replacement therapy cause an increase in bile lithogenity.

Objective The Women's Health Initiative randomized hormone trials unexpectedly demonstrated an increase in early coronary events. In an effort to explain this finding, we examined lipoprotein particle concentrations and their interactions with hormone therapy in a case–control substudy. Methods and Results We randomized 16 608 postmenopausal women with intact uterus to conjugated estrogens 0.625 mg with medroxyprogesterone acetate 2.5 mg daily or to placebo, and 10 739 women with prior hysterectomy to conjugated estrogens 0.625 mg daily or placebo, and measured lipoprotein subclasses by nuclear magnetic resonance spectroscopy at baseline and year 1 in 354 women with early coronary events and matched controls. Postmenopausal hormone therapy raised high-density lipoprotein cholesterol and particle concentration and reduced low-density lipoprotein cholesterol (LDL-C; all P<0.001 versus placebo). In contrast, neither unopposed estrogen nor estrogen with progestin lowered low-density lipoprotein particle concentration (LDL-P). Conclusions Postmenopausal hormone therapy–induced reductions in LDL-C were not paralleled by favorable effects on LDL-P. This finding may account for the absence of coronary protection conferred by estrogen in the randomized hormone trials. PMID:18599797

Primary growth hormone insensitivity (Laron syndrome) and acquired hypothyroidism: a case report

PubMed Central

2011-01-01

Introduction Primary growth hormone resistance or growth hormone insensitivity syndrome, also known as Laron syndrome, is a hereditary disease caused by deletions or different types of mutations in the growth hormone receptor gene or by post-receptor defects. This disorder is characterized by a clinical appearance of severe growth hormone deficiency with high levels of circulating growth hormone in contrast to low serum insulin-like growth factor 1 values. Case presentation We report the case of a 15-year-old Caucasian girl who was diagnosed with Silver-Russell syndrome at the age of four and a half years. Recombinant growth hormone was administered for 18 months without an appropriate increase in growth velocity. At the age of seven years, her serum growth hormone levels were high, and an insulin-like growth factor 1 generation test did not increase insulin-like growth factor 1 levels (baseline insulin-like growth factor 1 levels, 52 μg/L; reference range, 75 μg/L to 365 μg/L; and peak, 76 μg/L and 50 μg/L after 12 and 84 hours, respectively, from baseline). The genetic analysis showed that the patient was homozygous for the R217X mutation in the growth hormone receptor gene, which is characteristic of Laron syndrome. On the basis of these results, the diagnosis of primary growth hormone insensitivity syndrome was made, and recombinant insulin-like growth factor 1 therapy was initiated. The patient's treatment was well tolerated, but unexplained central hypothyroidism occurred at the age of 12.9 years. At the age of 15 years, when the patient's sexual development was almost completed and her menstrual cycle occurred irregularly, her height was 129.8 cm, which is 4.71 standard deviations below the median for normal girls her age. Conclusion The most important functional tests for the diagnosis of growth hormone insensitivity are the insulin-like growth factor 1 generation test and genetic analysis. Currently, the only effective treatment is daily administration of recombinant insulin-like growth factor 1 starting from early childhood. However, these patients show a dramatically impaired final height. In our case, unexplained central hypothyroidism occurred during treatment. PMID:21745362

At the age of seven years, her serum growth hormone levels were high, and an insulin-like growth factor 1 generation test did not increase insulin-like growth factor 1 levels (baseline insulin-like growth factor 1 levels, 52 μg/L; reference range, 75 μg/L to 365 μg/L; and peak, 76 μg/L and 50 μg/L after 12 and 84 hours, respectively, from baseline). The genetic analysis showed that the patient was homozygous for the R217X mutation in the growth hormone receptor gene, which is characteristic of Laron syndrome. On the basis of these results, the diagnosis of primary growth hormone insensitivity syndrome was made, and recombinant insulin-like growth factor 1 therapy was initiated. The patient's treatment was well tolerated, but unexplained central hypothyroidism occurred at the age of 12.9 years. At the age of 15 years, when the patient's sexual development was almost completed and her menstrual cycle occurred irregularly, her height was 129.8 cm, which is 4.71 standard deviations below the median for normal girls her age. The most important functional tests for the diagnosis of growth hormone insensitivity are the insulin-like growth factor 1 generation test and genetic analysis. Currently, the only effective treatment is daily administration of recombinant insulin-like growth factor 1 starting from early childhood. However, these patients show a dramatically impaired final height. In our case, unexplained central hypothyroidism occurred during treatment.

Craniopharyngiomas (CPs) are benign brain tumors presenting frequently in childhood and are treated by surgery with or without radiotherapy. About 50% of cured patients suffer from eating disorders and obesity due to hypothalamic damage, as well as hypopituitarism, necessitating subsequent hormone substitution therapy. Gastric bypass surgery has been reported to be an efficient treatment strategy for morbid hypothalamic obesity. However, so far it is unknown whether oral hormone substitution is affected by impaired intestinal drug absorption, potentially leading to severe hypopituitarism or pituitary crisis. Four morbidly obese CP patients with panhypopituitarism treated by gastric bypass surgery were included in this retrospective analysis. Dosages of hormone substitution therapy, blood concentrations of hormones, potential complications of impaired drug absorption, and anthropometric characteristics were investigated pre- and postoperatively after 6 to 14 months and 13 to 65 months. In all CP patients (3 female/1 male; baseline body mass index, 49 ± 7 kg/m(2)), gastric bypass resulted in distinct weight loss (-35 ± 27 kg). In follow-up examinations, mean daily dosage of thyroid hormone (levothyroxinebaseline 156 ± 44 μg/day versus levothyroxinefollow-up 150 ± 30 μg/day), hydrocortisone (hydrocortisonebaseline 29 ± 12 mg/day versus hydrocortisonefollow-up 26 ± 2 mg/day), growth-hormone (somatotropinbaseline 0.9 ± 0.5 mg/day versus somatotropinfollow-up 1.0 ± 0.4 mg/day), and desmopressin (desmopressinbaseline 222 ± 96 μg/day versus desmopressinfollow-up 222 ± 96 μg/day) substitution was unchanged. No patient developed adrenal insufficiency. Oral thyroid/hydrocortisone absorption testing performed in 1 patient indicated sufficient gastrointestinal drug absorption after bariatric surgery. Our preliminary results suggest that oral hormone substitution therapy is not impaired following gastric bypass operation in CP patients with morbid obesity, indicating that it might be a safe and effective treatment strategy.

Treatment of solid tumors by photodynamic therapy (PDT) was recently shown to trigger a strong acute phase response. Using the mouse Lewis lung carcinoma (LLC) model, the present study examined complement and pentraxin proteins as PDT-induced acute phase reactants. The results show a distinct pattern of changes in the expression of genes encoding these proteins in the tumor, as well as host liver and spleen, following PDT mediated by photosensitizer Photofrin™. These changes were influenced by glucocorticoid hormones, as evidenced by transcriptional activation of glucocorticoid receptor and the upregulation of gene encoding this receptor. The expression of gene for glucocorticoid-induced zipper (GILZ) protein, whose activity is particularly susceptible to glucocorticoid regulation, was also changed in PDT-treated tumors. A direct demonstration that tumor PDT induces glucocorticoid hormone upregulation is provided by documenting elevated levels of serum corticosterone in mice bearing PDT-treated LLC tumors. Tumor response to PDT was negatively affected by blocking glucocorticoid receptor activity, which suggests that glucocorticoid hormones have a positive impact on the therapeutic outcome with this therapy.

This study investigated associations between the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis, adiponectin, resistin and metabolic profile in 47 GH-deficient children before and during 12 months of GH treatment. 23 short age-matched children without growth hormone deficiency (GHD) or any genetic or chronic disorders were recruited as controls at baseline. Metabolic evaluation included measurements of adiponectin, resistin, IGF-1, total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), glucose, insulin, glycated haemoglobin (HbA1c), thyroid stimulating hormone (TSH) and free thyroxine (free T4) concentrations. The GH-deficient children had significantly higher adiponectin (p<0.05) and total cholesterol (p<0.05) levels, and a significantly lower level of resistin (p<0.05) than the controls. Resistin at 6 months of GH treatment significantly correlated with changes in height SDS in that period (r=0.35) and with the level of fasting insulin (r=0.50), the HOMA-IR (r=0.56) and the QUICKI (r=-0.53) at 12 months of therapy. Adiponectin level at 12 months of GH treatment was significantly associated with changes in HDL-C within the first 6 (r=0.73) and within 12 (r=0.56) months of therapy, while resistin significantly correlated with an increment in IGF-1 within 12 months of treatment (r=0.49) and with total-C at 12 months (r=0.56). Untreated GH-deficient children had higher adiponectin and lower resistin levels than healthy short children without GHD. Adiponectin and resistin levels did not change significantly during the first 12 months of GH therapy. Good responders to GH treatment had a tendency for higher resistin level during GH therapy, which positively correlates with the insulin resistance parameters.

We performed a screening on patients with traumatic brain injury (TBI) or subarachnoid hemorrhage (SAH) to determine the prevalence of post-traumatic hypopituitarism in neurorehabilitation in a cross-sectional, observational single-center study. In addition, the therapeutic consequences of our screening were analyzed retrospectively. From February 2006 to August 2009, patients between 18 and 65 years (n=509) with the diagnosis of TBI (n=340) or SAH (n=169) were screened within two weeks of admittance to neurorehabilitation as clinical routine. Blood was drawn to determine fasting cortisol, free thyroxine (fT4), prolactin, testosterone or estradiol, and insulin-like growth factor I (IGF-I). Patients with abnormalities in the screening or clinical signs of hypopituitarism received further stimulation tests: growth hormone releasing hormone -L-arginine-test and adrenocorticotrophic hormone (ACTH)-test (n=36); ACTH-test alone (n=26); or insulin tolerance test (n=56). In our screening of 509 patients, 28.5% showed lowered values in at least one hormone of the hypothalamus-pituitary axis and 4.5% in two or more axes. The most common disturbance was a decrease of testosterone in 40.7% of all men (in the following 13/131 men were given substitution therapy). Low fT4 was detected in 5.9% (n=3 were given substitution therapy). Low IGF-I was detected in 5.8%, low cortisol in 1.4%, and low prolactin in 0.2%; none were given substitution therapy. Further stimulation tests revealed growth hormone deficiency in 20.7% (n=19/92) and hypocortisolism in 23.7% (n=28/118). Laboratory values possibly indicating hypopituitarism (33%) were common but did not always implicate post-traumatic hypopituitarism. Laboratory values possibly indicating hypopituitarism were common in our screening but most patients were clinically not diagnosed as pituitary insufficient and did not receive hormone replacement therapy. A routine screening of all patients in neurorehabilitation without considering the time since injury, the severity of illness and therapeutic consequences seems not useful.

Hormonal therapy to the brain-dead organ donor can include thyroid hormone (triiodothyronine [T3] or levothyroxine [T4]), antidiuretic hormone, corticosteroids, or insulin. There has been a controversy on whether thyroid hormone enables more organs to be procured. Data on 63,593 donors of hearts and lungs (2000-2009) were retrospectively reviewed. Documentation on T3/T4 was available in all donors (study 1), and in 40,124 details of all 4 hormones were recorded (study 2). In this cohort, group A (23,022) received T3/T4 and group B (17,102) no T3/T4. Univariate analyses and multiple regressions were performed. Posttransplant graft and recipient survival at 1 and 12 months were compared. In study 1, 30,962 donors received T3/T4, with 36.59% providing a heart and 20.05% providing 1 or both lungs. Of the 32,631 donors who did not receive T3/T4, only 29.62% provided a heart and 14.61% provided lungs, an increase of 6.97% hearts and 5.44% lungs from T3/T4-treated donors (both P < 0.0001). In study 2, 34.99% of group A provided a heart and 20.99% provided lungs. In group B only 25.76% provided a heart and 15.09% provided lungs, an increase of 9.23% (hearts) and 5.90% (lungs), respectively, in group A (both P < 0.0001). The results of multiple regression analyses indicated a beneficial effect of T3/T4 on heart (P < 0.0001) and lung (P < 0.0001) procurement independent of other factors. T3/T4 therapy to the donor was associated with either improved posttransplant graft and recipient survival or no difference in survival. T3/T4 therapy results in more transplantable hearts and lungs, with no detriment to posttransplant graft or recipient survival. Copyright © 2015 Elsevier Inc. All rights reserved.

Divergent findings on the quality of life (QoL) and the psychosocial functioning of adults treated during childhood with growth hormone (GH) because of GH deficiency (GHD) have been reported. In the present study we evaluated the QoL and the perception of the effect of former GH treatment in Belgian young adults with childhood GHD. Thirty-six patients (22 males) were included in the study. They all were treated during childhood with GH for GHD. QoL was evaluated with a standardised questionnaire: the Quality of Life Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA). Psychosocial functioning, sexual experience and schooling were evaluated by semi-structured interviews and questionnaires. The influence of gender, type of hormone deficiency (isolated GHD vs multiple pituitary hormone deficiencies [MPHD]), age at the start of GH therapy (before 12 yr vs after 12 yr) and the height deficit at the start of GH therapy (< -3 SDS vs > -3 SDS) were studied. In addition, the patients' and parents' perception of height and of the effect of GH treatment was retrospectively evaluated by semi-structured interviews. Age (mean +/- SD) at the time of evaluation was 20.0 +/- 1.3 yr and final height was -0.5 +/- 0.9 SDS, comparable to mid-parental height (-0.6 +/- 0.8 SDS). The QoL-AGHDA score was 9 +/- 6. About half of the patients, especially those in whom GH treatment was started after the age of 12 years, complained of retrospective difficulties with self-confidence and social contact, and about one-quarter of the patients had current difficulties with self-confidence, social contact, contact with the opposite sex and with emotional life. Only 44% of the patients had had sexual intercourse--none of those with MPHD. According to the parents, the patients had and still have more difficulties with self-confidence and social contact than their siblings and/or peers, and they needed and still need more emotional support. In one out of four patients the parents expected difficulties in finding a job, in one out of three patients parents expected difficulties in leaving home or in having a stable relationship. The educational level of patients with a height deficit < -3 SDS at start of GH therapy was lower than in patients with a height deficit > -3 SDS. According to the parents, about half of the patients, especially those with MPHD, had more study problems compared to siblings. In all patients, satisfaction with final height and GH therapy was obvious. In conclusion, the psychosocial outcome of young adults with childhood GHD was more satisfying than in previous studies. This could be due to a more adequate GH treatment with better final height results. Nevertheless, more difficulties with respect to psychosocial functioning were observed in patients with MPHD, in patients in whom GH treatment was started after 12 years of age and in patients with a height deficit < -3 SDS at the start of GH therapy, underlining the need for early diagnosis and treatment of childhood GHD, and of continuing medical follow-up and psychosocial counselling, particularly in these subgroups of patients with GHD.

To examine the associations between hormonal contraceptive use and measures of HIV disease progression and antiretroviral treatment (ART) effectiveness. A prospective cohort study of women with prevalent HIV infection in St. Petersburg, Russia, was conducted. After contraceptive counseling, participants chose to use combined oral contraceptives (COCs), depot-medroxyprogesterone acetate (DMPA), a copper intrauterine device (IUD) or male condoms for pregnancy prevention. Among participants not using ART at enrollment, we used multivariate Cox regression to assess the association between current (time-varying) contraceptive use and disease progression, measured by the primary composite outcome of CD4 decline to <350 cells/mm(3), ART initiation or death. Among participants using ART at enrollment, we used linear mixed models to estimate the predicted mean CD4 change at select time points by contraceptive method. During a total of 5233 months follow-up among participants not using ART with enrollment CD4 ≥350 cells/mm(3) (n=315), 97 experienced disease progression. Neither current use of COCs [adjusted hazard ratio (aHR) 0.91, 95% confidence interval (CI) 0.56-1.48] nor DMPA (aHR 1.28, 95% CI 0.71-2.31) was associated with a statistically significant increased risk for disease progression compared with use of nonhormonal methods (IUD or condoms). Among participants using ART at enrollment (n=77), we found no statistically significant differences in the predicted mean changes in CD4 cell count comparing current use of COCs (p=.1) or DMPA (p=.3) with nonhormonal methods. Hormonal contraceptive use was not significantly associated with measures of HIV disease progression or ART effectiveness among women with prevalent HIV infection.

Neoadjuvant hormonal therapy is generally considered a valid option for hormone receptor positive breast cancer (BC) patients who are unfit for chemotherapy or surgery. Whilst numerous studies analyzed efficacy of neoadjuvant chemotherapy (CT) or endocrine therapy (HT) alone in hormone receptor positive patients, there is a lack of research looking at the usefulness of a preoperative combinatorial approach of CT and HT in this patient subgroup. Using a predictive model previously described in the literature, developed to analyze the probability of benefit from preoperative chemotherapy, we were able to compare pathological complete response (pCR) rates expected with the use of CT alone with the pCR rates reported in a population of 192 patients treated with the combination of tamoxifen plus anthracycline-based CT at Cremona Hospital between 2003 and 2006. Even with a relatively small patient population, this approach provided insightful information for the selection of hormone receptor positive BC patients most likely to benefit from the use of preoperative HT and CT in combination. Whilst no statistically significant benefit was obtained with the addition of tamoxifen to neoadjuvant chemotherapy in the entire population, or in any of the molecular stratification subgroups, the analysis of the calibration curve showed that a combinatorial approach may improve pCR in patients with luminal B tumors. More specific trials should be designed to confirm our initial results. To the best of our knowledge, this is the first report investigating the efficacy of the combination of CT and HT in the neoadjuvant treatment of hormone receptor positive BC.

Progesterone receptor (PR) is strongly associated with disease prognosis and therapeutic efficacy in hormone related diseases such as endometriosis and breast, ovarian, and uterine cancers. Receptor status is currently determined by immunohistochemistry assays. However, noninvasive PR imaging agents could improve disease detection and help elucidate pathological molecular pathways, leading to new therapies and animal disease models. A series of water-soluble PR-targeted magnetic resonance imaging (MRI) probes were synthesized using Cu(I)-catalyzed click chemistry and evaluated in vitro and in vivo. These agents demonstrated activation of PR in vitro and preferential accumulation in PR(+) compared to PR(−) human breast cancer cells with low toxicity. In xenograft tumor models, the agents demonstrated enhanced signal intensity in PR(+) tumors compared to PR(−) tumors. The results suggest that these agents may be promising MRI probes for PR(+) diseases. PMID:21972997

Obesity and Appetite Control

Suzuki, Keisuke; Jayasena, Channa N.; Bloom, Stephen R.

2012-01-01

Obesity is one of the major challenges to human health worldwide; however, there are currently no effective pharmacological interventions for obesity. Recent studies have improved our understanding of energy homeostasis by identifying sophisticated neurohumoral networks which convey signals between the brain and gut in order to control food intake. The hypothalamus is a key region which possesses reciprocal connections between the higher cortical centres such as reward-related limbic pathways, and the brainstem. Furthermore, the hypothalamus integrates a number of peripheral signals which modulate food intake and energy expenditure. Gut hormones, such as peptide YY, pancreatic polypeptide, glucagon-like peptide-1, oxyntomodulin, and ghrelin, are modulated by acute food ingestion. In contrast, adiposity signals such as leptin and insulin are implicated in both short- and long-term energy homeostasis. In this paper, we focus on the role of gut hormones and their related neuronal networks (the gut-brain axis) in appetite control, and their potentials as novel therapies for obesity. PMID:22899902

Sex differences in Parkinson's disease.

Parkinson's disease (PD) displays a greater prevalence and earlier age at onset in men. This review addresses the concept that sex differences in PD are determined, largely, by biological sex differences in the NSDA system which, in turn, arise from hormonal, genetic and environmental influences. Current therapies for PD rely on dopamine replacement strategies to treat symptoms, and there is an urgent, unmet need for disease modifying agents. As a significant degree of neuroprotection against the early stages of clinical or experimental PD is seen, respectively, in human and rodent females compared with males, a better understanding of brain sex dimorphisms in the intact and injured NSDA system will shed light on mechanisms which have the potential to delay, or even halt, the progression of PD. Available evidence suggests that sex-specific, hormone-based therapeutic agents hold particular promise for developing treatments with optimal efficacy in men and women. Copyright © 2014 The Authors.

Purpose To investigate the role of out-of-pocket cost supports through the Medicare Part D Low-Income Subsidy on disparities in breast cancer hormonal therapy persistence and adherence by race or ethnicity. Methods A nationwide cohort of women age ≥ 65 years with a breast cancer operation between 2006 and 2007 and at least one prescription filled for oral breast cancer hormonal therapy was identified from all Medicare D enrollees. The association of race or ethnicity with nonpersistence (90 consecutive days with no claims for a hormonal therapy prescription) and nonadherence (medication possession rate < 80%) was examined. Survival analyses were used to account for potential differences in age, comorbidity, or intensity of other treatments. Results Among the 25,111 women in the study sample, 77% of the Hispanic and 70% of the black women received a subsidy compared with 21% of the white women. By 2 years, 69% of black and 70% of Hispanic patients were persistent compared with 61% of white patients. In adjusted analyses, patients in all three unsubsidized race or ethnicity groups had greater discontinuation than subsidized groups (white patients: hazard ratio [HR], 1.83; 95% CI, 1.70 to 1.95; black patients: HR, 2.09; 95% CI, 1.73 to 2.51; Hispanic patients: HR, 3.00; 95% CI, 2.37 to 3.89). Racial or ethnic persistence disparities that were present for unsubsidized patients were not present or reversed among subsidized patients. All three subsidized race or ethnicity groups also had higher adherence than all three unsubsidized groups, although with the smallest difference occurring in black women. Conclusion Receipt of a prescription subsidy was associated with substantially improved persistence to breast cancer hormonal therapy among white, black, and Hispanic women and lack of racial or ethnic disparities in persistence. Given high subsidy enrollment among black and Hispanic women, policies targeted at low-income patients have the potential to also substantially reduce racial and ethnic disparities. PMID:27998232

Purpose Patients with recurrent prostate cancer after local treatment make up a heterogeneous population for whom androgen deprivation therapy (ADT) is the usual treatment. The purpose of this randomized phase II trial was to investigate the efficacy and toxicity of short-course ADT with or without bevacizumab in men with hormone-sensitive prostate cancer. Patients and Methods Eligible patients had an increasing prostate-specific antigen (PSA) of ≤ 50 ng/mL and PSA doubling time of less than 18 months. Patients had either no metastases or low burden, asymptomatic metastases (lymph nodes < 3 cm and five or fewer bone metastases). Patients were randomly assigned 2:1 to a luteinizing hormone-releasing hormone agonist, bicalutamide and bevacizumab or ADT alone, for 6 months. The primary end point was PSA relapse-free survival (RFS). Relapse was defined as a PSA of more than 0.2 ng/mL for prostatectomy patients or PSA of more than 2.0 ng/mL for primary radiation therapy patients. Results Sixty-six patients received ADT + bevacizumab and 36 received ADT alone. Patients receiving ADT + bevacizumab had a statistically significant improvement in RFS compared with patients treated with ADT alone (13.3 months for ADT + bevacizumab v 10.2 months for ADT alone; hazard ratio, 0.47; 95% CI, 0.29 to 0.77; log-rank P = .002). Hypertension was the most common adverse event in patients receiving ADT + bevacizumab (36%). Conclusion ADT combined with bevacizumab resulted in an improved RFS for patients with hormone-sensitive prostate cancer. Long-term follow-up is needed to determine whether some patients have a durable PSA response and are able to remain off ADT for prolonged periods. Our data provide rationale for combining vascular endothelial growth factor–targeting therapy with ADT in hormone-sensitive prostate cancer. PMID:27044933

OBJECTIVE: To characterize thyroid disturbances induced by interferon-alpha and ribavirin therapy in patients with chronic hepatitis C. INTRODUCTION: Interferon-alpha is used to treat chronic hepatitis C infections. This compound commonly induces both autoimmune and non-autoimmune thyroiditis. METHODS: We prospectively selected 26 patients with chronic hepatitis C infections. Clinical examinations, hormonal evaluations, and color-flow Doppler ultrasonography of the thyroid were performed before and during antiviral therapy. RESULTS: Of the patients in our study, 54% had no thyroid disorders associated with the interferon-alpha therapy but showed reduced levels of total T3 along with a decrease in serum alanine aminotransferase. Total T4 levels were also reduced at 3 and 12 months, but free T4 and thyroid stimulating hormone (TSH) levels remained stable. A total of 19% of the subjects had autoimmune interferon-induced thyroiditis, which is characterized by an emerge of antithyroid antibodies or overt hypothyroidism. Additionally, 16% had non-autoimmune thyroiditis, which presents as destructive thyroiditis or subclinical hypothyroidism, and 11% remained in a state of euthyroidism despite the prior existence of antithyroidal antibodies. Thyrotoxicosis with destructive thyroiditis was diagnosed within three months of therapy, and ultrasonography of these patients revealed thyroid shrinkage and discordant change in the vascular patterns. DISCUSSION: Decreases in the total T3 and total T4 levels may be related to improvements in the hepatocellular lesions or inflammatory changes similar to those associated with nonthyroidal illnesses. The immune mechanisms and direct effects of interferon-alpha can be associated with thyroiditis. CONCLUSION: Interferon-alpha and ribavirin induce autoimmune and non-autoimmune thyroiditis and hormonal changes (such as decreased total T3 and total T4 levels), which occur despite stable free T4 and TSH levels. A thyroid hormonal evaluation, including the analysis of the free T4, TSH, and antithyroid antibody levels, should be mandatory before therapy, and an early re-evaluation within three months of treatment is necessary as an appropriate follow-up.

To characterize thyroid disturbances induced by interferon-alpha and ribavirin therapy in patients with chronic hepatitis C. Interferon-alpha is used to treat chronic hepatitis C infections. This compound commonly induces both autoimmune and non-autoimmune thyroiditis. We prospectively selected 26 patients with chronic hepatitis C infections. Clinical examinations, hormonal evaluations, and color-flow Doppler ultrasonography of the thyroid were performed before and during antiviral therapy. Of the patients in our study, 54% had no thyroid disorders associated with the interferon-alpha therapy but showed reduced levels of total T3 along with a decrease in serum alanine aminotransferase. Total T4 levels were also reduced at 3 and 12 months, but free T4 and thyroid stimulating hormone (TSH) levels remained stable. A total of 19% of the subjects had autoimmune interferon-induced thyroiditis, which is characterized by an emerge of antithyroid antibodies or overt hypothyroidism. Additionally, 16% had non-autoimmune thyroiditis, which presents as destructive thyroiditis or subclinical hypothyroidism, and 11% remained in a state of euthyroidism despite the prior existence of antithyroidal antibodies. Thyrotoxicosis with destructive thyroiditis was diagnosed within three months of therapy, and ultrasonography of these patients revealed thyroid shrinkage and discordant change in the vascular patterns. Decreases in the total T3 and total T4 levels may be related to improvements in the hepatocellular lesions or inflammatory changes similar to those associated with nonthyroidal illnesses. The immune mechanisms and direct effects of interferon-alpha can be associated with thyroiditis. Interferon-alpha and ribavirin induce autoimmune and non-autoimmune thyroiditis and hormonal changes (such as decreased total T3 and total T4 levels), which occur despite stable free T4 and TSH levels. A thyroid hormonal evaluation, including the analysis of the free T4, TSH, and antithyroid antibody levels, should be mandatory before therapy, and an early re-evaluation within three months of treatment is necessary as an appropriate follow-up.

The studies indicate the complex etiology of abnormal glucose metabolism in the Turner syndrome (TS). In the light of these carbohydrate disorders a therapy with recombinant growth hormone (rGH) in TS may be associated with complications, as growth hormone has a diabetogenic potential. Perinatal history is unknown since the patient was adopted at the age of 4 years. At 11 years old, due to typical phenotype, TS was diagnosed. The karyotype was 45,X[43]/46,X,i(X)(q10)[7]. At the same age, basing on laboratory results, insulin dependent diabetes was diagnosed and the conventional insulin therapy was initiated. During the hospitalization, at the age of 12 years, the patient was 123.5cm (-4.4SD). At the same age rGH tre-atment was initiated, with the dose 0.045 mg/kg/d. After 3 months of therapy the height velocity rose to 8.2 cm/ year. At the age of 13 years, substitution with 17β-estradiol was started. After 3 years and 4 months the growth hormone treatment was stopped because of poor height velocity. The final height of the patient was 140 cm (-4,OSD). Two years after the end of rGH treatment the height was 141.2 cm. After termination of rGH treatment the need for daily insulin dose decreased from 50-60U/d to 38-44U/d. The decision of rGH therapy in TS with diabetes is certainly difficult. While starting the growth hormone treatment the clinician must keep in mind the risk of metabolic complications, but also the awareness that gives the patient a chance to improve the final height. In terms of the proper psycho-emotional development the reduction of growth deficit is very important. © Polish Society for Pediatric Endocrinology and Diabetology.

The effectiveness of pulsatile gonadotropin-releasing hormone (GnRH) therapy in patients with congenital combined pituitary hormone deficiency (CCPHD) has not been investigated because of the limited number of patients, as well as these patients' presumed pituitary hypoplasia, poor gonadotrophic cell reserve, and impaired gonadotrophic response to GnRH. To assess the pituitary response to pulsatile GnRH therapy in men with CCPHD. Prospective, self-controlled, 3-month clinical trial. University endocrine clinic. Men with hypogonadotropic hypogonadism caused by CCPHD. Pulsatile GnRH was administered subcutaneously for 3 months. Primary endpoints were total serum testosterone, testicular volume, and luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels. Secondary endpoints included occurrence of spermatogenesis. A total of 40 men with CCPHD completed the study. Of these, 60% (24 of 40) showed a good response to pulsatile GnRH treatment (response group). At 3 months, their LH and FSH levels increased to within the normal range and their testosterone levels increased to 8.67 ± 4.83 nmol/L. Of the patients in the response group, 33.3% (8 of 24) of them achieved spermatogenesis. The remaining 40% (16 of 40) of patients had a poor response to pulsatile GnRH treatment. Magnetic resonance imaging (MRI) did not reveal any correlation between pituitary response and pituitary height and/or integrity of the pituitary stalk. This study suggests that gonadotrophs in patients with CCPHD can exist and be functional-even with MRI evidence of pituitary hypoplasia or dysplasia. Pulsatile GnRH therapy restored pituitary-testis axis function in 60% of patients with CCPHD. These results may directly guide the clinical therapeutic choice. Copyright © 2017 Endocrine Society

Untreated transsexuals have a brain cortical phenotype. Cross-sex hormone treatments are used to masculinize or feminize the bodies of female-to-male (FtMs) or male-to-female (MtFs) transsexuals, respectively. A longitudinal design was conducted to investigate the effects of treatments on brain cortical thickness (CTh) of FtMs and MtFs. This study investigated 15 female-to-male (FtMs) and 14 male-to-female (MtFs) transsexuals prior and during at least six months of cross-sex hormone therapy treatment. Brain MRI imaging was performed in a 3-Tesla TIM-TRIO Siemens scanner. T1-weighted images were analyzed with FreeSurfer software to obtain CTh as well as subcortical volumetric values. Changes in brain CTh thickness and volumetry associated to changes in hormonal levels due to cross-sex hormone therapy. After testosterone treatment, FtMs showed increases of CTh bilaterally in the postcentral gyrus and unilaterally in the inferior parietal, lingual, pericalcarine, and supramarginal areas of the left hemisphere and the rostral middle frontal and the cuneus region of the right hemisphere. There was a significant positive correlation between the serum testosterone and free testosterone index changes and CTh changes in parieto-temporo-occipital regions. In contrast, MtFs, after estrogens and antiandrogens treatment, showed a general decrease in CTh and subcortical volumetric measures and an increase in the volume of the ventricles. Testosterone therapy increases CTh in FtMs. Thickening in cortical regions is associated to changes in testosterone levels. Estrogens and antiandrogens therapy in MtFs is associated to a decrease in the CTh that consequently induces an enlargement of the ventricular system. © 2014 International Society for Sexual Medicine.

To ascertain the impact of pituitary size as judged by Magnetic Resonance Imaging (MRI), on response to Growth Hormone (GH) therapy in GH deficient children. Thirty nine children (9.1 ± 2.7 y, 22 boys) with non-acquired GH deficiency (21 Isolated GH deficiency and 18 Combined pituitary hormone deficiency) were consecutively recruited and followed up for one year. Clinical, radiological (bone age and MRI) and biochemical parameters were studied. Children with hypoplastic pituitary (pituitary height < 3 mm) had more severe height deficit (height for age Z-score -6.0 vs. -5.0) and retardation of skeletal maturation (bone age chronological age ratio of 0.59 vs. 0.48) at baseline as compared to children with normal pituitary heights (p < 0.05 for both). After one year of GH therapy, height for age Z scores and percentage change in height for age Z scores were significantly higher in children with hypoplastic pituitaries (13.8 ± 3.6 and 28.7 % vs. 11.2 ± 4.1 and 21.4 %). Significant co-relation was observed between pituitary height and height for age Z-scores at baseline (r = 0.39, p < 0.05). The predicted adult height using Tanner Whitehouse-2 equations improved from 140.8 to 152.3 cm in children with hypoplastic pituitary when compared to an increase from 145.8 to 153.5 cm observed in children with normal pituitary height (p < 0.05). Indian growth hormone deficient children with hypoplastic pituitary respond better to therapy with GH in short term.

Blood lipids and high-sensitivity C-reactive protein (hs-CRP) are altered by hormone therapy. The goal of the present study was to determine whether lipids and hs-CRP have predictive value for hormone therapy benefit or risk for coronary heart disease events in postmenopausal women without previous cardiovascular disease. A nested case-control study was performed in the Women's Health Initiative hormone trials. Baseline lipids and hs-CRP were obtained from 271 incident patients with coronary heart disease (cases) and 707 controls. In a combined trial analysis, favorable lipid status at baseline tended to predict better coronary heart disease outcomes when using conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA). Women with a low-density lipoprotein (LDL)/high-density lipoprotein (HDL) cholesterol ratio <2.5 had no increase in risk of coronary heart disease when using CEE with or without MPA (odds ratio 0.60, 95% confidence interval 0.34 to 1.06), whereas women with an LDL/HDL cholesterol ratio > or =2.5 had increased risk of coronary heart disease (odds ratio 1.73, 95% confidence interval 1.18 to 2.53, p for interaction = 0.02). Low hs-CRP added marginally to the value of LDL/HDL ratio <2.5 when predicting coronary heart disease benefit on hormone therapy. In conclusion, postmenopausal women with undesirable lipid levels had excess coronary heart disease risk when using CEE with or without MPA. However, women with favorable lipid levels, especially LDL/HDL cholesterol ratio <2.5, did not have increased risk of coronary heart disease with CEE with or without MPA irrespective of hs-CRP.

This study evaluated the augmentation of venlafaxine with hormone therapy in the treatment of postmenopausal depression. The hormones evaluated were estrogen (0.625 mg) in combination with medroxyprogesterone acetate (2.5 mg) and methyltestosterone (2.5 mg). Seventy-two menopausal women (mean age: 53.6 +/- 4.27 years) diagnosed with depression (Montgomery-Asberg Depression Rating Scale [MADRS] scores > or = 20) were treated with venlafaxine and one of the following hormone therapy combinations, in a double-blind regimen: estrogen + medroxyprogesterone + methyltestosterone (group 1, n = 20); estrogen + medroxyprogesterone acetate (group 2, n = 20); methyltestosterone only (group 3, n = 16); and no hormone therapy (group 4, n = 16). Study duration was 24 weeks. Primary efficacy outcome was remission according to the MADRS, whereas secondary efficacy measures included the Clinical Global Impression (CGI), Blatt-Kupperman Index, and Women's Health Questionnaire (WHQ). Forty-eight patients completed the study. All groups showed significant improvement from baseline. Group 3 demonstrated significant improvement on the MADRS compared with placebo (group 4) at weeks 20 (P = 0.048) and 24 (P = 0.030); effect size 8.04 (0.83; 15.26) (P = 0.029), but also had the highest dropout rate. Groups 1 and 3 had significant CGI improvement rates compared with placebo: 42.23% (P = 0.012) and 44.45% (P = 0.08), respectively. There were no differences in the WHQ or BKI scores among the groups. Methyltestosterone 2.5 mg had the highest effect size compared with placebo, but the high dropout rate prevented its efficacy from being determined. Estrogen plus medroxyprogesterone, combined with methyltestosterone or otherwise, demonstrated a trend toward increased efficacy of venlafaxine. Further larger-scale clinical trials are needed to elucidate the findings of this pilot study.

Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

Background Clinical guidelines recommend that women with hormone-receptor positive breast cancer receive endocrine therapy (selective estrogen receptor modulators [SERMs] or aromatase inhibitors [AIs]) for five years following diagnosis. Objective To examine utilization and adherence to therapy for SERMs and AIs in Medicare Part D prescription drug plans. Data Linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data. Study design We identified 15,542 elderly women diagnosed with hormone-receptor positive breast cancer in years 2003-2005 (the latest SEER data at the time of the study) and enrolled in a Part D plan in 2006 or 2007 (the initial years of Part D). This permitted us to compare utilization and adherence to therapy at various points within the recommended five-year timeframe for endocrine therapy. SERM and AI use was measured from claim records. Non-adherence to therapy was defined as a medication possession ratio of less than 80 percent. Principal findings Between May 2006 and December 2007, 22 percent of beneficiaries received SERM, 52 percent AI, and 26 percent received neither. The percent receiving any endocrine therapy decreased with time from diagnosis. Among SERM and AI users, 20-30 percent were non-adherent to therapy; out-of-pocket costs were higher for AI than SERM and were strongly associated with non-adherence. For AI users without a low income subsidy, adherence to therapy deteriorated after reaching the Part D coverage gap. Conclusions Many elderly breast cancer patients were not receiving therapy for the recommended five years following diagnosis. Choosing a Part D plan that minimizes out-of-pocket costs is critical to ensuring beneficiary access to essential medications. PMID:22340780

Sex hormones, aging, and Alzheimer’s disease

Barron, Anna M.; Pike, Christian J.

2012-01-01

A promising strategy to delay and perhaps prevent Alzheimer’s disease (AD) is to identify the age-related changes that put the brain at risk for the disease. A significant normal age change known to result in tissue-specific dysfunction is the depletion of sex hormones. In women, menopause results in a relatively rapid loss of estradiol and progesterone. In men, aging is associated with a comparatively gradual yet significant decrease in testosterone. We review a broad literature that indicates age-related losses of estrogens in women and testosterone in men are risk factors for AD. Both estrogens and androgens exert a wide range of protective actions that improve multiple aspects of neural health, suggesting that hormone therapies have the potential to combat AD pathogenesis. However, translation of experimental findings into effective therapies has proven challenging. One emerging treatment option is the development of novel hormone mimetics termed selective estrogen and androgen receptor modulators. Continued research of sex hormones and their roles in the aging brain is expected to yield valuable approaches to reducing the risk of AD. PMID:22201929

To review palbociclib, a novel small-molecule inhibitor of cyclin-dependent kinases 4 and 6, and its current place in therapy for the treatment of hormone receptor (HMR)-positive, human epidermal growth factor receptor 2 (Her2)-negative advanced breast cancer. Four phase I trials, 2 phase II trials, and 1 phase III trial were identified from May 2004 to May 2015 using PubMed, American Society of Clinical Oncology (ASCO) abstracts, and European Society of Medical Oncology (ESMO) abstracts. In the first-line setting, the phase II PALbociclib: Ongoing trials in the Management of breast cAncer (PALOMA)-1 trial randomized patients to receive letrozole alone or letrozole plus palbociclib 125 mg daily for 3 weeks, followed by 1 week off, as initial therapy for advanced breast cancer. The investigator-assessed median progression-free survival (PFS) was 20. 2 months for the combination versus 10.2 months for letrozole alone (hazard ratio [HR] = 0.488; 95% CI = 0.319-0.748; 1-sided P = 0.0004). The ensuing Food and Drug Administration approval of palbociclib was given a "breakthrough therapy" designation, where preliminary evidence suggests substantial improvement over existing therapies for a serious or life-threatening disease. A confirmatory phase III trial, PALOMA-2, is under way. In patients who were previously treated with endocrine therapy for advanced breast cancer, the phase III PALOMA-3 trial randomized patients to fulvestrant plus palbociclib versus fulvestrant plus placebo. The investigator-assessed median PFS at the time of a preplanned analysis was 9.2 months with palbociclib-fulvestrant compared with 3.8 months with placebo-fulvestrant (HR = 0.42; 95% CI = 0.32-0.56; P < 0.001). Palbociclib, the first-in-class CDK4/6 inhibitor, significantly extended PFS in combination with endocrine therapy in the first and subsequent lines of treatment for HMR-positive, Her2-negative advanced breast cancer. © The Author(s) 2015.

To explore the effects of valproate (VPA) on endocrine system in adolescent and reproductive female patients with epilepsy. A total of 30 adolescent and reproductive female patients with a diagnosis of epilepsy at our hospital during July 2009 to March 2010 were recruited. All cases with magnesium VPA alone were included. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), estradiol (E2), progesterone (P) and testosterone (T) were detected respectively at pre-therapy and 3, 6 and 12 months post-therapy. And the changes of menstruation and ovaries were recorded. The serum concentration of PRL was lower at 3 and 6 months post-therapy than that at pre-therapy. There was significant difference (P = 0.010 and 0.014). The serum concentration of E2 significantly decreased after a 3-month therapy of valproate (P < 0.05). While comparing the parameter's level between the initial test and at a 3, 6 and 12-month follow-up, the level of P significantly decreased in the later groups than that of the former one while the level of T showed a marked increase. The levels of FSH and LH were not significantly different at pre- and post-therapy. And 6 (20%) of them presented with menstrual dysfunctions and 3 (10%) polycystic ovary. The valproate therapy can not only cause the changes of endocrine system and hormonal levels, but also induce such endocrine dysfunction syndromes as menstrual suspension and polycystic ovary. It eventually causes polycystic ovary syndrome.

The advent of sensitive genetic testing modalities for the diagnosis of Prader-Willi syndrome has helped to define not only the phenotypic features of the syndrome associated with the various genotypes but also to anticipate clinical and psychological problems that occur at each stage during the life span. With advances in hormone replacement therapy, particularly growth hormone children born in circumstances where therapy is available are expected to have an improved quality of life as compared to those born prior to growth hormone. This manuscript was prepared as a primer for clinicians-to serve as a resource for those of you who care for children and adults with Prader-Willi syndrome on a daily basis in your practices. Appropriate and anticipatory interventions can make a difference. PMID:22008714

The aim of this study was to explore the association between depressive symptoms and some variables related to the reproductive life, such as history of premenstrual dysphoric disorder, antecedent of postpartum depression, previous use of hormonal contraceptives, and current hot flushes, in a group of perimenopausal women attending a menopause clinic. Perimenopausal women, 45 to 55 years old, who had not received hormonal replacement therapy and/or psychotropic medication, were invited to participate in this study. 141 perimenopausal women were included; we obtained their psychiatric and gynecological data, and we evaluated their depressive symptomatology using the CES-D scale. There were a significantly higher number of cases of previous depressive episodes, PMDD and PPD history in depressed patients compared with non-depressed women; current hot flushes prevalence was similar between depressed and non-depressed women. Patients with a PMDD history were more likely to have experienced previous depressive episodes, a PPD history and high levels of depression. Variables associated with the level of depression were a previous history of PMDD, current hot flushes, and previous depressive episodes. The occurrence of perimenopausal depression is related to a previous history of PMDD, PPD, and depressive episodes; hot flushes only increase the severity of the depressive episode.

A partial differential equation model and its reduction to an ordinary differential equation model for prostate tumor growth under intermittent hormone therapy.

PubMed

Tao, Youshan; Guo, Qian; Aihara, Kazuyuki

2014-10-01

Hormonal therapy with androgen suppression is a common treatment for advanced prostate tumors. The emergence of androgen-independent cells, however, leads to a tumor relapse under a condition of long-term androgen deprivation. Clinical trials suggest that intermittent androgen suppression (IAS) with alternating on- and off-treatment periods can delay the relapse when compared with continuous androgen suppression (CAS). In this paper, we propose a mathematical model for prostate tumor growth under IAS therapy. The model elucidates initial hormone sensitivity, an eventual relapse of a tumor under CAS therapy, and a delay of a relapse under IAS therapy, which are due to the coexistence of androgen-dependent cells, androgen-independent cells resulting from reversible changes by adaptation, and androgen-independent cells resulting from irreversible changes by genetic mutations. The model is formulated as a free boundary problem of partial differential equations that describe the evolution of populations of the abovementioned three types of cells during on-treatment periods and off-treatment periods. Moreover, the model can be transformed into a piecewise linear ordinary differential equation model by introducing three new volume variables, and the study of the resulting model may help to devise optimal IAS schedules.

ESTROGENS AND AGE-RELATED MEMORY DECLINE IN RODENTS: WHAT HAVE WE LEARNED AND WHERE DO WE GO FROM HERE?

PubMed Central

Frick, Karyn M.

2009-01-01

The question of whether ovarian hormone therapy can prevent or reduce age-related memory decline in menopausal women has been the subject of much recent debate. Although numerous studies have demonstrated a beneficial effect of estrogen and/or progestin therapy for certain types of memory in menopausal women, recent clinical trials suggest that such therapy actually increases the risk of cognitive decline and dementia. Because rodent models have been frequently used to examine the effects of age and/or ovarian hormone deficiency on mnemonic function, rodent models of age-related hormone and memory decline may be useful in helping to resolve this issue. This review will focus on evidence suggesting that estradiol modulates memory, particularly hippocampal-dependent memory, in young and aging female rats and mice. Various factors affecting the mnemonic response to estradiol in aging females will be highlighted to illustrate the complications inherent to studies of estrogen therapy in aging females. Avenues for future development of estradiol-based therapies will also be discussed, and it is argued that an approach to drug development based on identifying the molecular mechanisms underlying estrogenic modulation of memory may lead to promising future treatments for reducing age-related mnemonic decline.

Cellular immunity and immunopathology in autoimmune Addison's disease.

PubMed

Bratland, Eirik; Husebye, Eystein S

2011-04-10

Autoimmune adrenocortical failure, or Addison's disease, is a prototypical organ-specific autoimmune disorder. In common with related autoimmune endocrinopathies, Addison's disease is only manageable to a certain extent with replacement therapy being the only treatment option. Unfortunately, the available therapy does not restore the physiological hormone levels and biorhythm. The key to progress in treating and preventing autoimmune Addison's disease lies in improving our understanding of the predisposing factors, the mechanisms responsible for the progression of the disease, and the interactions between adrenal antigens and effector cells and molecules of the immune system. The aim of the present review is to summarize the current knowledge on the role of T cells and cellular immunity in the pathogenesis of autoimmune Addison's disease.

Is excessive weight gain after ablative treatment of hyperthyroidism due to inadequate thyroid hormone therapy?

PubMed

Tigas, S; Idiculla, J; Beckett, G; Toft, A

2000-12-01

There is controversy about the correct dose and form of thyroid hormone therapy for patients with hypothyroidism. Despite restoration of serum thyrotropin (TSH) concentrations to normal, many patients complain of excessive weight gain. We have compared weight at diagnosis of hyperthyroidism with that when euthyroid, evidenced by a stable, normal serum TSH concentration, with or without thyroxine (T4) replacement therapy, in patients treated with an 18-month course of antithyroid drugs (43 patients), surgery (56 patients), or 13I (34 patients) for Graves' disease. In addition, weights were recorded before and after treatment of 25 patients with differentiated thyroid carcinoma by total thyroidectomy, 131I, and long-term T4 suppressive therapy, resulting in undetectable serum TSH concentrations. Mean weight gain in patients with Graves' disease who required T4 replacement therapy following surgery was significantly greater than in those of the same age, sex, and severity of hyperthyroidism rendered euthyroid by surgery (3.9 kg) (p < 0.001) or at the end of a course of antithyroid drugs (4.1 kg) (p < 0.001). Weight gain was similar in those requiring T4 replacement following surgery or 131T therapy (10.4 versus 10.1 kg). In contrast, ablative therapy combined with suppression of TSH secretion by T4 in patients with differentiated thyroid carcinoma did not result in weight gain. The excessive weight gain in patients becoming hypothyroid after destructive therapy for Graves' disease suggests that restoration of serum TSH to the reference range by T4 alone may constitute inadequate hormone replacement.

Adult growth hormone (GH) deficiency is a well-recognized clinical syndrome with adverse health consequences. Many of these may improve after replacement therapy with recombinant GH. This treatment induces an increase in lean body mass and a decrease in fat mass. In long-term studies, bone mineral density increases and muscle strength improves. Health-related quality of life tends to increase after treatment with GH. Lipid profile and markers of cardiovascular risk also improve with therapy. Nevertheless, GH replacement therapy is not without risk. According to some studies, GH increases blood glucose, body mass index and waist circumference and may promote long-term development of diabetes and metabolic syndrome. Risk of neoplasia does not appear to be increased in adults treated with GH, but there are some high-risk subgroups. Methodological shortcomings and difficulties inherent to long-term studies prevent definitive conclusions about the relationship between GH and survival. Therefore, research in this field should remain active. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

Re-framing the representation of women in advertisements for hormone replacement therapy.

This article examines and presents examples of contemporary advertising within the medical and health professions that continue the process and organisation of knowledge about women and their reproductive bodies. It draws on feminist and poststructural perspectives to inform a critical evaluation of the visual representations of menopausal women and hormone replacement therapy. These representations work to construct certain definitions of the feminine that sustain and support existing contradictory cultural meanings and values about menopause. I argue that the images continue to misrepresent and define what forms of femininity and sexual gender are desirable and acceptable for menopausal women. The article addresses the problems of gender discrimination and bias within the advertising industry, and illustrates the ways in which readers of visual texts may be influenced by stereotypic assumptions concerning a woman's lived experience of menopause. It illustrates how specific symbolic images directed towards men and women for hormone replacement therapy, testosterone deficiency and sexual dysfunction influence the viewer's decision making and action responses.

Women using menopausal hormone therapy (MHT) are at increased risk to develop breast cancer (BC). To detect genetic modifiers of the association between current use of MHT and BC risk, we conducted a meta-analysis of four genome-wide case-only studies followed by replication in eleven case-control studies. We used a case-only design to assess interactions between single nucleotide polymorphisms (SNPs) and current MHT use on risk of overall and lobular BC. The discovery stage included 2,920 cases (541 lobular) from four genome-wide association studies. The top 1,391 SNPs showing P-values for interaction (Pint) <3.0×10−03 were selected for replication using pooled case-control data from eleven studies of the Breast Cancer Association Consortium, including 7,689 cases (676 lobular) and 9,266 controls. Fixed effects meta-analysis was used to derive combined Pint. No SNP reached genome-wide significance in either the discovery or combined stage. We observed effect modification of current MHT use on overall BC risk by two SNPs on chr13 near POMP (combined Pint≤8.9×10−06), two SNPs in SLC25A21 (combined Pint≤4.8×10−05), and three SNPs in PLCG2 (combined Pint≤4.5×10−05). The association between lobular BC risk was potentially modified by one SNP in TMEFF2 (combined Pint≤2.7×10−05), one SNP in CD80 (combined Pint≤8.2×10−06), three SNPs on chr17 near TMEM132E (combined Pint≤2.2×10−06), and two SNPs on chr18 near SLC25A52 (combined Pint≤4.6×10−05). In conclusion, polymorphisms in genes related to solute transportation in mitochondria, transmembrane signaling and immune cell activation are potentially modifying BC risk associated with current use of MHT. These findings warrant replication in independent studies. PMID:24080446

The metastatic spread of breast carcinoma to the stomach is rare. There are a small number of previous studies that report metastases from the breast to the stomach and these provide limited information regarding this infrequent event. Consequently, the clinicopathological features, clinical outcomes and the optimal treatment for these patients remain to be elucidated. In the present study, 78 cases of gastric metastases from breast cancer, including the current case, were identified from previous studies between 1960 and 2015. The clinicopathological features of primary breast tumors and metastatic gastric lesions, including initial stage, tumor size, hormone receptor status, treatment modalities and overall survival (OS) rate, were analyzed. The patients were all female and the median age at the time of gastric metastasis diagnosis was 59 years old (range, 38-86 years). The majority of the patients initially presented with stage II breast cancer (35.9%) and abdominal pain was the most common symptom of gastric metastases (75.6%). A total of 51/78 patients (65.4%) were identified to have a history of invasive lobular breast carcinoma and the majority of gastric tumors were positive for hormonal receptors and human epidermal growth factor receptor 2 (HER-2) negative (estrogen receptor, 94.0%; progesterone receptor, 68.3%; HER-2, 5.9%). Furthermore, in the univariate analysis, multiple organs involved prior to or at the time of gastric metastases were diagnosed and multiple gastric lesions and peritoneal carcinomatosis were significantly correlated with OS. Additionally, salvage hormonal therapy, but not surgery or chemotherapy, significantly extended OS. However, in the multivariate analysis, metastasis prior to stomach involvement was the only independent indicator of poor OS. In conclusion, physicians must be vigilant when patients with breast cancer history present with gastrointestinal symptoms, despite gastric metastasis from breast cancer being rare. An appropriate systemic therapeutic strategy that includes hormonal therapy may be beneficial for this group of patients.

The quality and quantity of bone formed in tooth extraction sockets impact implant therapy. Therefore, the establishment of a new approach to enhance bone formation and to minimize bone resorption is important for the success of implant therapy. In this study, we investigated whether intermittent parathyroid hormone (PTH) therapy enhanced bone formation in grafted sockets. Tooth extractions of the maxillary first molars were performed in rats, and the sockets were grafted with xenograft. Intermittent PTH was administered either for 7 days before extractions, for 14 days after extractions, or both. The effect of PTH therapy on bone formation in the grafted sockets was assessed using microcomputed tomography at 14 days after extractions. PTH therapy for 7 days before extractions was not effective to augment bone fill, whereas PTH therapy for 14 days after operation significantly augmented bone formation in the grafted sockets. Intermittent PTH therapy starting right after tooth extractions significantly enhanced bone fill in the grafted sockets, suggesting that PTH therapy can be a strong asset for the success of the ridge preservation procedure.

Menopause is caused by changes in the function of the hypothalamic-pituitary-gonadal (HPG) axis that controls reproduction. Hypophysiotropic gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus orchestrate the activity of this axis and are regulated by hormonal feedback loops. The mechanisms by which GnRH responses to the primary regulatory sex-steroid hormone, estradiol (E2) are still poorly understood in the context of menopause. Our goal was to determine whether the G protein-coupled estrogen receptor (GPER) is co-expressed in adult primate GnRH neurons, and whether this changes with aging and/or E2 treatment. We used immunofluorescence double labeling to characterize the co-expression of GPER in GnRH perikarya and terminals in the hypothalamus. Young and aged rhesus macaques were ovariectomized and given long-term (~2 year) hormone treatments (E2, E2 + progesterone, or vehicle) selected to mimic currently prescribed hormone replacement therapies used for the alleviation of menopausal symptoms in women. We found that about half of GnRH perikarya co-expressed GPER, while only about 12% of GnRH processes and terminals in the median eminence (ME) were double labeled. Additionally, many GPER labeled processes were in direct contact with GnRH neurons, often wrapped around the perikarya and processes and in close proximity in the ME. These results extend prior work by showing robust colocalization of GPER in GnRH in a clinically relevant model, and support the possibility that GPER-mediated E2 regulation of GnRH occurs both in the soma and terminals in nonhuman primates.
