Full Text Available Abstract Background Publication of results from the Women's Health Initiative study in July 2002 was a landmark event in biomedical science related to postmenopausal women. The purpose of this study was to describe the impact of new hormone therapy recommendations on patients' attitudes and decision-making in a primary care practice. Methods A questionnaire including structured and open-ended questions was administered in a family practice office waiting room from August through October 2003. Rationale for taking or not taking hormone therapy was specifically sought. Women 50–70 years old attending for office visits were invited to participate. Data were analyzed qualitatively and with descriptive statistics. Chart review provided medication use rates for the entire practice cohort of which the sample was a subset. Results Respondents (n = 127 were predominantly white and well educated, and were taking hormone therapy at a higher rate (38% than the overall rate (26% for women of the same age range in this practice. Belief patterns about hormone therapy were, in order of frequency, 'use is risky', 'vindication or prior beliefs', 'benefit to me outweighs risk', and 'unaware of new recommendations'. Twenty-eight out of 78 women continued hormones use after July 2002. Of 50 women who initially stopped hormone therapy after July 2002, 12 resumed use. Women who had stopped hormone therapy were a highly symptomatic group. Responses with emotional overtones such as worry, confusion, anger, and grief were common. Conclusion Strategies for decision support about hormone therapy should explicitly take into account women's preferences about symptom relief and the trade-offs among relevant risks. Some women may need emotional support during transitions in hormone therapy use.

Fourteen hyperthyroid patients (11 men, three women), ages 28 to 66, were followed with serial measurements of serum thyroid hormone levels for 1 mo after therapy with I-131. Twelve patients had diffuse toxic goiters (25 to 70 g in size); two patients had multinodular glands (40 to 100 g). The patients were taking no antithyroid medications; ten patients were treated with propranolol. All patients received the equivalent of 5000 rad, except the two with multinodular glands, who received larger doses. There was no consistent pattern of serum T 4 and T 3 levels after the I-131 therapy. For the entire group, there was no significant increase of the mean serum hormone concentration. One group (three patients) had a mean T 4 increase of 28% and a T 3 increase of 91% above baseline at Days 10--11. Seven patients had minimal increases of hormone levels at Days 2--3, and a third group (four paients) had no increase of thyroid hormones after I-131 therapy. The patients with no rise in hormone concentrations had smaller goiters than the other groups. There was no correlation of the dose of radioactive iodine, or of the initial hormone concentration, with the rises or declines of T 4 and T 3 levels after I-131 therapy. Radioiodine therapy caused no significant increase of serum T 4 and T 3 concentrations in the majority of patients

The effects of growth hormone (GH) therapy were studied in 6 children, previously treated for brain tumours which did not directly involve the hypothalamic-pituitary axis, and who had received cranial irradiation between 2.1 and 10 years earlier. All 6 were short with a standing height standard deviation score (SDS) from -1.7 to -3.3. Impaired growth hormone responses to an insulin tolerance test (ITT) were observed in all 6 and a Bovril stimulation test in 5 children. The remainder of pituitary function was essentially normal. All 6 were prepubertal and 5 had a retarded bone age. Subsequently all received human GH in a dose of 5 units 3 times weekly for 1 year. The growth rate in each was at least 2 cm greater during the treatment year than the pre-treatment year.(author)

Williams, Aaron O; Kocherill, Paul G; Wallace, Michelle; Forman, Jeffrey D

1996-01-01

Purpose: To evaluate the efficacy and toxicity of intermittent hormonal therapy in the treatment of residual/recurrent prostate cancer. Materials and Methods: Seventeen patients with biochemical evidence of residual/recurrent prostate cancer were initially treated with radiation therapy (RT)(13), neo-adjuvant hormonal therapy and RT (3), or RT following prostatectomy (1). The mean follow-up time was 19.4 months from the initiation of hormonal therapy. Hormonal therapy consisted of an LH-RH agonist alone (7), an anti-androgen alone (1) or a combination of both (9). Hormonal therapy was continued until the prostatic specific antigen (PSA) level became undetectable. IHT was reinstituted when the PSA reached a pre-determined level, usually greater than or equal to 10ng/ml. Results: The mean time from completion of primary treatment to the initiation of hormonal therapy was 32.5 months. The mean PSA at the start of the first cycle of hormonal therapy was 43.9ng/ml, the second cycle, 11.9ng/ml and the third cycle, 24ng/ml. The mean PSA levels at the end of the first and second cycle of hormonal therapy were .48 and .42ng/ml, respectively. No patient has yet completed the third cycle of hormonal therapy. The average duration of hormonal therapy was 10 months for the first cycle and 4 months for the second cycle. The mean intermittent time off hormones were 9.3 months between cycles 1 and 2, and 10 months between cycles 2 and 3. No patient has yet become refractory to hormonal therapy. Currently all patients are alive. All patients experienced hot flashes and decreased libido at varying degrees during treatment. Thirty-five percent experienced gynecomastia. During the intervals between hormonal therapy, most patients reported a decrease in hot flashes. Conclusion: This analysis supplies preliminary evidence that intermittent hormonal therapy is a viable option in patients with biochemical evidence of disease following initial therapy. It is associated with less treatment

Preliminary studies of plasma growth hormone releasing activity during medical therapy of acromegaly

International Nuclear Information System (INIS)

Hagen, T.C.; Lawrence, A.M.; Kirsteins, L.

1978-01-01

The in vitro growth hormone releasing activity of plasma obtained from six acromegalic subjects was measured before and during therapy. In five subjects, plasmas were obtained before and during successful medical therapy with medroxyprogesterone acetate (MPA). The sixth subject was sampled before and after transphenoidal Sr 90 -induced hypopituitarism. All subjects had a decrement in fasting growth hormone levels with respective therapies (29-88%). The in vitro growth hormone released from Rhesus monkey anterior pituitaries was assessed after incubating one lateral half in control plasma (pre-therapy) and the contralateral pituitary half in plasma obtained during or after therapy. Studies with plasmas obtained from the five patients successfully treated with MPA showed a decrease in growth hormone releasing activity during therapy in all (18-57%). Plasma obtained after Sr 90 pituitary ablation in the sixth subject had 35% more growth hormone releasing activity than obtained before therapy. These results suggest that active acromegalics who respond to MPA with significantly lowered growth hormone levels may actually achieve this response because of a decrease in growth hormone releasing factor measured peripherally. The opposite response in one acromegalic subject, following Sr 90 pituitary ablation and hypopituitarism, suggests that growth hormone releasing factor secretion may increase when growth hormone levels are lowered by ablative therapy.

Although hormonal therapy is effective for treatment of prostate cancer, its effect in the treatment of metastatic spinal cord compression (MSCC) has not been established. The objective of this study was to clarify the efficacy of conservative treatment of MSCC-induced paralysis resulting from prostate cancer for patients without a previous treatment history. We reviewed data from 38 patients with MSCC-induced paralysis from newly diagnosed prostate cancer who presented to our service between 1984 and 2010. Conservative treatment consisted of hormonal therapy with external radiation therapy (ERT). Patient demographic data, treatment details, involved spine MRI images, complications, and the course of neurologic recovery were investigated. Twenty-five patients were treated conservatively. Mean follow-up period was 36.8 months. Sixteen patients (two with Frankel B, 14 with Frankel C) were unable to walk at initial presentation. After initiating conservative treatment, 75% (12 of 16) of these patients regained the ability to walk within 1 month, 88% (14 in 16) did so within 3 months, and all non-ambulatory patients did so within 6 months. No one had morbid complications. Four patients who did not regain the ability to walk at 1 month were found to have progressed to paraplegia rapidly, and tended to have severe compression as visualized on MRI, with a delay in the start of treatment in comparison with those who did so within 1 month (21.0 vs. 7.8 days). Hormonal therapy associated with ERT is an important option for treatment of MSCC resulting from newly diagnosed prostate cancer. (author)

Progressive pituitary hormone deficiency following radiation therapy in adults

International Nuclear Information System (INIS)

Loureiro, Rafaela A.; Vaisman, Mario

2004-01-01

Hypopituitarism can be caused by radiation therapy, even when it is not directly applied on the hypothalamic-pituitary axis, and can lead to anterior pituitary deficiency mainly due to hypothalamic damage. The progressive loss of the anterior pituitary hormones usually occurs in the following order: growth hormone, gonadotropin hormones, adrenocorticotropic hormone and thyroid-stimulating hormone. Although there are several different tests available to confirm anterior pituitary deficiency, this paper will focus on the gold standard tests for patients submitted to radiation therapy. We emphasize that the decline of anterior pituitary function is time- and dose-dependent with some variability among the different axes. Therefore, awareness of the need of a joint management by endocrinologists and oncologists is essential to improve treatment and quality of life of the patients. (author)

Full Text Available Deficiency of estrogen hormone will result in either long-term or short-term health problems which may reduce the quality of life. There are numerous methods by which the quality of female life can be achieved. Since the problems occuring are due to the deficiency of estrogen hormone, the appropriate method to tackle the problem is by administration of estrogen hormone. The administration of hormone replacement therapy (HRT with estrogen may eliminate climacteric complaints, prevent osteoporosis, coronary heart disease, dementia, and colon cancer. Although HRT has a great deal of advantage, its use is still low and may result in controversies. These controversies are due to fact that both doctor and patient still hold on to the old, outmoded views which are not supported by numerous studies. Currently, the use of HRT is not only based on experience, or temporary observation, but more on evidence based medicine. (Med J Indones 2001; 10: 182-6Keywords: controversies, HRT

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 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.

Abnormal Bleeding during Menopause Hormone Therapy: Insights for Clinical Management

2013-01-01

Full Text Available Objective Our objective was to review the involved mechanisms and propose actions for controlling/treating abnormal uterine bleeding during climacteric hormone therapy. Methods A systemic search of the databases SciELO, MEDLINE, and Pubmed was performed for identifying relevant publications on normal endometrial bleeding, abnormal uterine bleeding, and hormone therapy bleeding. Results Before starting hormone therapy, it is essential to exclude any abnormal organic condition, identify women at higher risk for bleeding, and adapt the regimen to suit eachwoman's characteristics. Abnormal bleeding with progesterone/progestogen only, combined sequential, or combined continuous regimens may be corrected by changing the progestogen, adjusting the progestogen or estrogen/progestogen doses, or even switching the initial regimen to other formulation. Conclusion To diminish the occurrence of abnormal bleeding during hormone therapy (HT, it is important to tailor the regimen to the needs of individual women and identify those with higher risk of bleeding. The use of new agents as adjuvant therapies for decreasing abnormal bleeding in women on HT awaits future studies.

Full Text Available The last decade has brought many challenges and uncertainties regarding the use of menopausal hormone therapy in women. Two early key studies, the Heart and Estrogen/Progestin Replacement Study (HERS and the Women's Health Initiative (WHI failed to prove beneficial effects of exogenous estrogen, and estrogen combined with progestin, in cardiovascular prevention. More recent studies, however, introduced the concept of a possible “window-of-opportunity” for hormonal therapy, in which menopausal hormone therapy is used early after the onset of menopause, and may lead to more favorable, cardio-protective outcomes. Despite the increasing wealth of clinical data, menopausal hormone therapy is not currently recommended for primary or secondary prevention of coronary heart disease in women. Further research is needed to understand the risk-benefit balance of menopausal hormone therapy. Resumen: La última década ha traído muchos retos e incertidumbres respecto al uso de la terapia hormonal en la menopausia en mujeres. Dos estudios tempranos clave, el Heart and Estrogen/Progestin Replacement Study (HERS [Estudio del Corazón y Reemplazo de Estrógeno/Progestina] y la Womeńs Health Initiative (WHI [Iniciativa de Salud de la Mujer] no pudieron demostrar los efectos benéficos del estrógeno exógeno y el estrógeno combinado con la progestina, en la prevención cardiovascular. Sin embargo, estudios más recientes han introducido el concepto de una posible “ventana de oportunidad” para la terapia hormonal, en donde la terapia hormonal en la menopausia se emplea tempranamente luego del inicio de la menopausia, y que puede llevar a resultados más favorables y cardioprotectores. A pesar de la creciente riqueza en datos clínicos, en la actualidad no se recomienda la terapia hormonal en la menopausia para la prevención primaria o secundaria de la enfermedad coronaria en mujeres.

Emerging evidence implicates metabolic syndrome as a long-term cancer risk factor but also suggests that certain cancer therapies may increase patients’ risk of developing metabolic syndrome secondary to cancer therapy. In particular, breast cancer and prostate cancer are driven in part by sex hormones, thus treatment for both diseases is often based on hormone-modifying therapy. Androgen suppression therapy in men with prostate cancer is associated with dyslipidemia, increasing risk of cardi...

Purpose: To determine the rate of tumor response and patterns of relapse following combined hormonal-radiation therapy of adenocarcinoma of the prostate and to measure the survival in a group of men with tumor metastatic to pelvic lymph nodes. Methods and Materials: 66 patients with adenocarcinoma of the prostate with pathologically confirmed pelvic lymph node involvement were treated with combined radiation therapy and hormonal therapy. An additional five patients declined hormonal therapy. The patients treated with combined therapy represented a group with locally advanced disease including 44 patients (67%) with T3 or T4 tumors and 51 patients (80%) had N2 or N3 lymph node metastases. The pelvic lymph nodes were treated to a dose of 45 Gy and the prostate was boosted to a dose of 65 to 71 Gy. Hormonal therapy began up to 2 months before radiation and continued indefinitely. Patients were allowed to select their hormonal therapy and could choose DES (2 patients), orchiectomy (21 patients), LHRH agonist (7 patients) or combined androgen blockade (34 patients). Results: Median follow-up is 49 months (range 12 to 131 months) and 21 patients have been followed for longer than 5 years. There have been 15 recurrences the entire group including three local recurrences in the prostate, seven patients with distant metastases, four patients with biochemical recurrences without clinical evidence of disease, and one patient where the location was unknown. Two of the PSA recurrences occurred in patients who elected to discontinue hormones after less than 3 years of therapy. The overall survival at 5 and 8 years is 94 and 84%, the clinical disease free survival is 85 and 67%, and the biochemical disease-free survival is 78 and 47%. There was no increased toxicity of the combined modality regimen compared to the expected effects of radiation and hormonal therapy. Conclusion: Combined hormonal and radiation therapy represents an effective treatment option for patients with

Hormonal therapy in female pattern hair loss

Directory of Open Access Journals (Sweden)

Kevin R. Brough

2017-03-01

Full Text Available Female pattern hair loss is the most common cause of hair loss in women and one of the most common problems seen by dermatologists. This hair loss is a nonscarring alopecia in which loss occurs on the vertex scalp, generally sparing the frontal hairline. Hair loss can have significant psychosocial effects on patients, and treatment can be long and difficult. The influence of hormones on the pathogenesis of female pattern hair loss is not entirely known. The purpose of this paper is to review physiology and potential hormonal mechanisms for the pathogenesis of female pattern hair loss. We also discuss the current hormonal and hormone-modifying therapies that are available to providers as they partner with patients to treat this frustrating issue.

Therapy of Hypoparathyroidism by Replacement with Parathyroid Hormone

Directory of Open Access Journals (Sweden)

Lars Rejnmark

2014-01-01

Full Text Available Hypoparathyroidism (HypoPT is a state of hypocalcemia due to inappropriate low levels of parathyroid hormone (PTH. HypoPT is normally treated by calcium supplements and activated vitamin D analogues. Although plasma calcium is normalized in response to conventional therapy, quality of life (QoL seems impaired and patients are at increased risk of renal complications. A number of studies have suggested subcutaneous injections with PTH as an alternative therapy. By replacement with the missing hormone, urinary calcium may be lowered and QoL may improve. PTH replacement therapy (PTH-RT possesses, nevertheless, a number of challenges. If PTH is injected only once a day, fluctuations in calcium levels may occur resulting in hypercalcemia in the hours following an injection. Twice-a-day injections seem to cause less fluctuation in plasma calcium but do stimulate bone turnover to above normal. Most recently, continuous delivery of PTH by pump has appeared as a feasible alternative to injections. Plasma calcium levels do not fluctuate, urinary calcium is lowered, and bone turnover is only stimulated modestly (into the normal range. Further studies are needed to assess the long-term effects. If beneficial, it seems likely that standard treatment of HypoPT in the future will change into replacement therapy with the missing hormone.

Children with hypoplastic pituitary (pituitary 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 growth hormone deficient children with hypoplastic pituitary respond better to therapy with GH in short term.

Hypoparathyroidism: Replacement Therapy with Parathyroid Hormone

Directory of Open Access Journals (Sweden)

Lars Rejnmark

2015-12-01

Full Text Available Hypoparathyroidism (HypoPT is characterized by low serum calcium levels caused by an insufficient secretion of parathyroid hormone (PTH. Despite normalization of serum calcium levels by treatment with activated vitamin D analogues and calcium supplementation, patients are suffering from impaired quality of life (QoL and are at increased risk of a number of comorbidities. Thus, despite normalization of calcium levels in response to conventional therapy, this should only be considered as an apparent normalization, as patients are suffering from a number of complications and calcium-phosphate homeostasis is not normalized in a physiological manner. In a number of recent studies, replacement therapy with recombinant human PTH (rhPTH(1-84 as well as therapy with the N-terminal PTH fragment (rhPTH(1-34 have been investigated. Both drugs have been shown to normalize serum calcium while reducing needs for activated vitamin D and calcium supplements. However, once a day injections cause large fluctuations in serum calcium. Twice a day injections diminish fluctuations, but don't restore the normal physiology of calcium homeostasis. Recent studies using pump-delivery have shown promising results on maintaining normocalcemia with minimal fluctuations in calcium levels. Further studies are needed to determine whether this may improve QoL and lower risk of complications. Such data are needed before replacement with the missing hormone can be recommended as standard therapy.

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.

In the PALOMA-3 study, the combination of the CDK4 and CDK6 inhibitor palbociclib and fulvestrant was associated with significant improvements in progression-free survival compared with fulvestrant plus placebo in patients with metastatic breast cancer. Identification of patients most suitable for the addition of palbociclib to endocrine therapy after tumour recurrence is crucial for treatment optimisation in metastatic breast cancer. We aimed to confirm our earlier findings with this extended follow-up and show our results for subgroup and biomarker analyses. In this multicentre, double-blind, randomised phase 3 study, women aged 18 years or older with hormone-receptor-positive, HER2-negative metastatic breast cancer that had progressed on previous endocrine therapy were stratified by sensitivity to previous hormonal therapy, menopausal status, and presence of visceral metastasis at 144 centres in 17 countries. Eligible patients-ie, any menopausal status, Eastern Cooperative Oncology Group performance status 0-1, measurable disease or bone disease only, and disease relapse or progression after previous endocrine therapy for advanced disease during treatment or within 12 months of completion of adjuvant therapy-were randomly assigned (2:1) via a centralised interactive web-based and voice-based randomisation system to receive oral palbociclib (125 mg daily for 3 weeks followed by a week off over 28-day cycles) plus 500 mg fulvestrant (intramuscular injection on days 1 and 15 of cycle 1; then on day 1 of subsequent 28-day cycles) or placebo plus fulvestrant. The primary endpoint was investigator-assessed progression-free survival. Analysis was by intention to treat. We also assessed endocrine therapy resistance by clinical parameters, quantitative hormone-receptor expression, and tumour PIK3CA mutational status in circulating DNA at baseline.

Rousseau, M E

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.

Full Text Available Only orchiectomy is still commonly used today either as a single therapy or in combination regimens. Hypophysectomy & adrenalectomy showed such devastating effects on the endocrine equilibrium as to be inconsistent with an acceptable quality of life or even with survival. Chemical adrenalectomy was also tried with drugs (eg. aminoglutethmide, spironolactone leading to consequences superimposable to those of surgical adrenalectomy. Along with orchiectomy, three groups of substances are commonly used today for the hormonal therapy of prostate cancer: estrogens, LHRH agonists & anti androgens. Bilateral orchiectomy removes 90-95% of circulating testosterone. Clinical studies document 60-80% of positive responders to castration, on continued evaluation, relapse occurs usually within 6-24 months in responders, with a death rate of 50% within 6 months. The androgenic activity still remaining after castration may explain the partial & progressively decreasing effectiveness of this & other testosterone reducing therapies. Antiandrogens define substances that act directly at the target site, where interacting with steroid hormone receptors, they impede the binding of androgens. A trend towards the combination of testosterone-reducing & androgen-blocking treatment is developing in modern therapy of prostate cancer. This is due to the complementary characteristics of the two different pharmacological mechanisms that are involved. In this study castration+antiandrogen is compared to castration alone. The results demonstrate a significantly greater percentage of positive objective & subjective responses with antiandrogen than with placebo. In addition survival time was increased in patients treated with castration+antiandrogen than castration+placebo.

Full Text Available 2-Methoxyestradiol (2-ME has potent anti proliferative effects on cancer cells. Its utility alone or in combination with other therapies for treating prostate cancer, however, has not been fully explored. Androgendependent, independent human prostate cancer cells were examined in vivo for their response to combination therapy. Efficacy was assessed by terminal deoxynucleotide transferase-mediated dUTP nick-end labeling assay, measuring microvessel density (MVD in excised tumors. Animals harboring hormonedependent tumors treated with 2-ME alone, androgen deprivation therapy alone, or the combination of the two had a 3.1-fold, 5.3-fold, 10.1-fold increase in apoptosis, respectively. For hormone-independent tumors, treatment with 2-ME resulted in a 2.43-fold increase in apoptosis, a 73% decrease in MVD. 2-ME was most effective against hormone-dependent tumors in vivo, combination therapy resulted in a significant increase in efficacy compared to no treatment controls, trended toward greater efficacy than either 2-ME or androgen deprivation alone. Combination therapy should be investigated further as an additional therapeutic option for early prostate cancer.

Full Text Available Menopause is a key point moment in the specific aging process of women. It represents a universal evolution in life. Its initiation is defined by a 12-month amenorrhea following the ultimate menstrual period. It encompasses a series of different biologic and physiologic characteristics. This period of life appears to spot a decline in a series of skin functional performances initiating tissue atrophy, withering, and slackness. Any part of the skin is possibly altered, including the epidermis, dermis, hypodermis, and hair follicles. Hormone replacement therapy (oral and nonoral and transdermal estrogen therapy represent possible specific managements for women engaged in the climacteric phase. All the current reports indicate that chronologic aging, climacteric estrogen deficiency, and adequate hormone therapy exert profound effects on various parts of the skin.

Ten patients with newly diagnosed, advanced prostatic cancer were treated with radiotherapy and hormone therapy to improve tumor control and survival. Eight patients with hormonally relapsed prostatic cancer were treated with radiotherapy to improve their quality of life. Local control of the tumor was achieved in 9 of 10 patients with newly diagnosed, advanced prostatic cancer. Five of eight patients with hormonally relapsed prostatic cancer obtained improved quality of life. Combined radiotherapy and hormone therapy were effective in the treatment of newly diagnosed, advanced prostatic cancer, and radiotherapy was useful for improving the quality of life of patients with hormonally relapsed prostatic cancer.

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 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.

[Effects of growth hormone replacement therapy on bone metabolism].

Growth hormone (GH) as well as insulin like growth factor-1 (IGF-1) are essential hormones to maintain homeostasis of bone turnover by activating osteoblastogenesis and osteoclastogenesis. Results from GH replacement therapy for primary osteoporosis and adult-onset GH deficiency (AGHD) suggest that one year or more treatment period by this agent is required to gain bone mineral density (BMD) over the basal level after compensating BMD loss caused by dominant increase in bone resorption which was observed at early phase of GH treatment. A recent meta-analysis demonstrates the efficacy of GH replacement therapy on increases in BMD in male patients with AGHD. Additional analyses are needed to draw firm conclusions in female patients with AGHD, because insufficient amounts of GH might be administrated to them without considerations of influence of estrogen replacement therapy on IGF-1 production. Further observational studies are needed to clarify whether GH replacement therapy prevent fracture risk in these patients.

To evaluate the effects of hormone therapy (HT) on cognition and subjective quality of life (QoL) in recently postmenopausal women with cognitive complaints. Cognitive Complaints in Early Menopause Trial (COGENT) was a randomized, double-blind, placebo-controlled, multicenter, pilot study of 180 healthy postmenopausal women aged 45 to 55 years, randomly assigned to receive either placebo or conjugated equine estrogen 0.625 mg/medroxyprogesterone acetate 2.5 mg for 4 months. Outcome measures included memory, subjective cognition, QoL, sexuality, and sleep, which were assessed at baseline and month 4. The study was terminated before the expected final sample size of 275 due to a decrease in enrollment coinciding with the publication of findings from the Women's Health Initiative. There were no differences between groups on any cognitive or QoL measures, except for an increase in sexual interest and thoughts with HT. Modest negative effects on short- and long-term verbal memory approached significance (p or=0.45, this study suggests potential modest negative effects on verbal memory that are consistent with previous hormone therapy trials in older women.

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 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.

АBNORMAL UTERINE BLEEDING DURING МENOPAUSAL HORMONAL THERAPY

Directory of Open Access Journals (Sweden)

Ya. Z. Zaydieva

2015-01-01

Full Text Available Postmenopausal women using continuous combined estrogen/progestin therapy are likely to have irregular bleedings or spotting. Up to now, their causes remain unclear. Most investigators believe that a potential mechanism of abnormal bleedings during menopausal hormonal therapy could be a change in the ratio of pro- and anti-angiogenic factors, namely, of vascular endothelial growth factor to thrombospondin-1; alterations in metalloproteinases and their tissue inhibitors; changes in a tissue factor that is a mediator of endometrial hemostasis; as well as an increased number of endometrial leukocytes with predominance of uterine natural killer cells. As long as no link between bleeding discharge during continuous combined hormonal treatment and any of these  actors has been established, each and every of them is the subject of in vivo and in vitro investigations. At present, there are no  herapeutic methods to correct this complication of hormonal treatment. Patient monitoring to exclude neoplastic abnormalities in endometrium are of paramount importance.

Increasing research suggests that periodontal status is associated with hormone replacement therapy in postmenopausal women. This study was performed to assess the relationship between the number of natural teeth and ever use of hormone replacement therapy in postmenopausal women using nationally representative Korean data. Data from the Korea National Health and Nutrition Examination Survey between 2010 and 2012 were used, and the analysis in this study was confined to a total of 4869 respondents over 19 years old who had gone through menopause and who had no missing data for the reproductive factors and outcome variables in that study. The total number of natural teeth was then calculated after excluding third molars. The time of day when tooth brushing was done was recorded as representative oral health behavior. Multiple logistic regression analyses were used to assess association between the number of natural teeth and the use of hormone replacement therapy. Among participants who had ever used hormone replacement therapy, the proportions (percentage and standard error) with no teeth, 1-9 teeth, 10-19 teeth, 20-27 teeth, and 28 teeth were 5.0±2.4%, 6.7±1.4%, 12.5±1.7%, 18.9±1.0%, and 20.7±1.6%, respectively (Preplacement therapy, after adjustments. The analysis revealed that the use of hormone replacement therapy by postmenopausal women showed positive effects for retention of natural teeth. Lack of hormone replacement therapy may be considered to be an independent risk indicator for tooth loss in Korean postmenopausal women. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Purpose: To explore long-term immune responses after combined radio-gene-hormonal therapy. Methods and Materials: Thirty-three patients with prostate specific antigen 10 or higher or Gleason score of 7 or higher or clinical stage T2b to T3 were treated with gene therapy that consisted of 3 separate intraprostatic injections of AdHSV-tk on Days 0, 56, and 70. Each injection was followed by 2 weeks of valacyclovir. Intensity-modulated radiation therapy was delivered 2 days after the second AdHSV-tk injection for 7 weeks. Hormonal therapy was initiated on Day 0 and continued for 4 months or 2.3 years. Blood samples were taken before, during, and after treatment. Lymphocytes were analyzed by fluorescent antibody cell sorting (FACS). Results: Median follow-up was 26 months (range, 4-48 months). The mean percentages of DR + CD8 + T cells were increased at all timepoints up to 8 months. The mean percentages of DR + CD4 + T cells were increased later and sustained longer until 12 months. Long-term (2.3 years) use of hormonal therapy did not affect the percentage of any lymphocyte population. Conclusions: Sustained long-term (up to 8 to 12 months) systemic T-cell responses were noted after combined radio-gene-hormonal therapy for prostate cancer. Prolonged use of hormonal therapy does not suppress this response. These results suggest the potential for sustained activation of cell-mediated immune responses against cancer

Functional and molecular neuroimaging of menopause and hormone replacement therapy

Full Text Available The level of gonadal hormones to which the female brain is exposed considerably changes across the menopausal transition, which in turn, is likely to be of great relevance for neurodegenerative diseases and psychiatric disorders. However, the neurobiological consequences of these hormone fluctuations and of hormone replacement therapy in the menopause have only begun to be understood. This review summarizes the findings of thirty-four studies of human brain function, including functional magnetic resonance imaging, positron and single-photon computed emission tomography studies, in peri- and postmenopausal women treated with estrogen, or estrogen-progestagen replacement therapy. Seven studies using gonadotropin-releasing hormone agonist intervention as a model of hormonal withdrawal are also included. Cognitive paradigms are employed by the majority of studies evaluating the effect of unopposed estrogen or estrogen-progestagen treatment on peri- and postmenopausal women’s brain. In randomized-controlled trials, estrogen treatment enhances activation of fronto-cingulate regions during cognitive functioning, though in many cases no difference in cognitive performance was present. Progestagens seems to counteract the effects of estrogens. Findings on cognitive functioning during acute ovarian hormone withdrawal suggest a decrease in activation of the inferior frontal gyrus, thus essentially corroborating the findings in postmenopausal women. Studies of the cholinergic and serotonergic systems indicate these systems as biological mediators of hormonal influences on the brain. More, hormonal replacement appears to increase cerebral blood flow in cortical regions. On the other hand, studies on emotion processing in postmenopausal women are lacking. These results call for well-powered randomized-controlled multi-modal prospective neuroimaging studies as well as investigation on the related molecular mechanisms of effects of menopausal hormonal

Studies have shown associations of diabetes and endogenous hormones with exposure to a wide variety of organochlorines. We have previously reported positive associations of polychlorinated biphenyls (PCBs) and inverse associations of selected steroid hormones with diabetes in postmenopausal women previously employed in a capacitor manufacturing plant. This paper examines associations of PCBs with diabetes and endogenous hormones in 63 men previously employed at the same plant who in 1996 underwent surveys of their exposure and medical history and collection of bloods and urine for measurements of PCBs, lipids, liver function, hematologic markers and endogenous hormones. PCB exposure was positively associated with diabetes and age and inversely associated with thyroid stimulating hormone and triiodothyronine-uptake. History of diabetes was significantly related to total PCBs and all PCB functional groupings, but not to quarters worked and job score, after control for potential confounders. None of the exposures were related to insulin resistance (HOMA-IR) in non-diabetic men. Associations of PCBs with specific endogenous hormones differ in some respects from previous findings in postmenopausal women employed at the capacitor plant. Results from this study, however, do confirm previous reports relating PCB exposure to diabetes and suggest that these associations are not mediated by measured endogenous hormones.

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.

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.

PALBOCICLIB IN COMBINATION WITH HORMONE THERAPY FOR LUMINAL HER2-NEGATIVE METASTATIC BREAST CANCER: NEW HIGHLY EFFECTIVE STRATEGY OF DRUG TREATMENT

2017-01-01

Full Text Available The review considers a new oral targeted drug palbociclib and its place in treatment of luminal (estrogen receptor-positive HER2– metastatic breast cancer. The results of randomized clinical trials have shown that inclusion of palbociclib in various hormone therapy regimens for treatment of HER2– metastatic breast cancer with expression of estrogen receptors allows to significantly improve clinical outcomes and increase survival, objective response rate and its duration, as well as clinical benefit rate (CBR. Addition of palbociclib to letrozole in the 1st line hormone therapy or to fulvestrant in patients with progression at/after previous endocrine therapy increased progression-free survival in all groups irrespective of clinical characteristics, tumor progression, or expression of molecular markers mediating development of hormone resistance. The main adverse events associated with palbociclib were neutropenia, leukopenia and thrombocytopenia, but overall hematological toxicity was manageable, and the therapy itself was safe. This strategy received a “breakthrough therapy designation” from the experts and combines proven effectiveness and satisfactory tolerability, allows to maintain high quality of life, and should be prescribed to patients with luminal HER2– metastatic breast cancer.

Full Text Available 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

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. 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.

Full Text Available Stephen F Kemp, J Paul FrindikUniversity of Arkansas for Medical Sciences, Arkansas Children's Hospital, Little Rock, AR, USAAbstract: Growth hormone (GH was first used to treat a patient in 1958. For the next 25 years it was available only from cadaver sources, which was of concern because of safety considerations and short supply. In 1985, GH produced by recombinant DNA techniques became available, expanding its possible uses. Since that time there have been three indications approved by the US Food and Drug Administration (FDA for GH-deficiency states and nine indications approved for non-GH-deficiency states. In 2003 the FDA approved GH for use in idiopathic short stature (ISS, which may indirectly cover other diagnoses that have short stature as a feature. However, coverage for GH therapy is usually more reliably obtainable for a specific indication, rather than the ISS indication. Possible future uses for GH therapy could include the treatment of syndromes such as Russell–Silver syndrome or chondrodystrophy. Other non-short-stature indications could include wound healing and burns. Other uses that have been poorly studied include aging and physical performance, in spite of the interest already shown by elite athletes in using GH. The safety profile of GH developed over the past 25 years has shown it to be a very safe hormone with few adverse events associated with it. The challenge for the future is to follow these patients into adulthood to determine whether GH therapy poses any long-term risks.Keywords: growth hormone, somatotropin, anabolic, short stature

As the use of hormone replacement therapy for the menopausal women increases, some caution is advised, since there is an increased risk of breast cancer. Accordingly, the importance of regular mammography has been addressed. This cross-setional study analyzed the effects of different hormone therapies on mammographic density. Sixty-seven postemenopausal women who had completed one year of hormone therapy and had undergone follow-up mammography, were divided into two groups : Group I : continuous conjugated equine estrogen, 0.625mg, plus continuous medroxyprogesterone acetate, 2.5mg (n=48), Group II : continuous conjugated equine estrogen 0.625mg (n=19). The mammograms were read by two radiologists. With regard to the radiologists involved, interobserver reliabillity (kappa) was 0.70 and intraobserver reliability (kappa) was 0.51 and 0.67. Before hormone therapy, factors related to decreased mammographic density were age and number of full term pregnancies (p<0.05). After one year of hormone therapy, body fat showed a significant increase (p<0.05), but in spite of this, increased mammographic density induced by hormone therapy remained significantly high (p<0.05). Compared with Group II, Group I showed a significant increase in mammographic density (p<0.05). In Group I, mammographic density increased from P2 to DY pattern in two cases, but there was no such change in Group II. The increase of mammographic density seen in Group II was much more significant statistically than that seen in Group I. The mammograms of women who have undergone continuous combined hormone therapy should therefore be interpreted very cautiously.

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

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

Science.gov (United States)

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.

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.

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.

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

We evaluated the diagnostic capability of MRI in ovarian chocolate cysts treated by Danazol (analogue of testosterone). Both inversion recovery as T1-weighted image and long TE and TR spin echo as T2-weighted image were performed before and during hormonal therapy. Temporal change of signal intensity and size was evaluated in three ovarian chocolate cysts (stage II: 2 cases, stage III: 1 case by Beecham classification, 1966) using the 0.15-T MR system. The high intense signal from all of the cysts was seen on both T1 and T2 weighted images before treatment. There was marked decrease in size of the chocolate cysts during hormonal therapy, and they were of considerably lower signal intensity than initially on T2-weighted image. We concluded that MRI was useful to evaluate hormonal therapy for ovarian chocolate cysts.

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 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.

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 (high blood pressure: past menopausal hormone therapy use: 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.

Intrahepatic cholestasis of pregnancy predisposes women to liver disorders years after affected pregnancy. We compared the basal levels and responses of hyaluronic acid, a marker of liver fibrosis, and liver transaminases to postmenopausal hormone therapy in women with (n = 20) and without (n = 20) a history of intrahepatic cholestasis of pregnancy. This was a randomized, double-blind, placebo-controlled, crossover trial. Basal levels of hyaluronic acid were similar in both groups. Two weeks of oral estradiol 2.0 mg/day led to significant but similar (10.9% to 15.4%) rises in hyaluronic acid in both groups. Increasing the dose of oral estradiol to 4.0 mg/day resulted in normalization of the levels, whereas the addition of medroxyprogesterone acetate led to falls (11.0% to 10.7 %) in hyaluronic acid. Transdermal estradiol 50 microg led to a rise (3.2 %) in hyaluronic acid only in the control group. Other liver markers were normal at baseline and during hormone therapy. Normal basal levels and/or normal responses of hyaluronic acid and other liver markers to hormone therapy in women with previous intrahepatic cholestasis suggest that this therapy does not predispose these women to liver diseases.

Objective: The Women's Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS. Methods: We contacted 2,345 women at 14 WHIMS sites; scans were completed on 1,424 (61%) and 1,403 were accepted for analysis. The primary outcome measure was total ischemic lesion volume on brain MRI. Mean duration of on-trial HT or placebo was 4 (CEE+MPA) or 5.6 years (CEE-Alone) and scans were conducted an average of 3 (CEE+MPA) or 1.4 years (CEE-Alone) post-trial termination. Cross-sectional analysis of MRI lesions was conducted; general linear models were fitted to assess treatment group differences using analysis of covariance. A (two-tailed) critical value of α = 0.05 was used. Results: In women evenly matched within trials at baseline, increased lesion volumes were significantly related to age, smoking, history of cardiovascular disease, hypertension, lower post-trial global cognition scores, and increased incident cases of on- or post-trial mild cognitive impairment or probable dementia. Mean ischemic lesion volumes were slightly larger for the CEE+MPA group vs placebo, except for the basal ganglia, but the differences were not significant. Women assigned to CEE-Alone had similar mean ischemic lesion volumes compared to placebo. Conclusions: Conjugated equine estrogen–based hormone therapy was not associated with a significant increase in ischemic brain lesion volume relative to placebo. This finding was consistent within each trial and in pooled analyses across trials.

To examine the role of concurrent 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) use and postmenopausal hormone therapy on osteoporosis-related fractures. Case-control study. Data Source. Large integrated health plan in New Mexico. Patients. Case patients were 1001 women with incident fractures of the hip, wrist, forearm, or spine that occurred between January 1, 2000, and December 31, 2005, and controls were 2607 women without fractures during the same time frame; both groups were selected from the same population of women aged 50 years or older who utilized health plan services during the study time frame. Postmenopausal hormone therapy use was classified as "current" (12 mo before index date) or "never or past." The risk of fractures was ascertained among continuous (> or = 80% medication possession ratio during 12 mo before the index date) and current (3 mo before index date) statin users relative to patients without hyperlipidemia who did not use lipid-lowering drugs. The interaction between statins and hormone therapy was examined in multivariable logistic regression. The association between statin use and fractures was examined separately among current and never or past hormone therapy users after controlling for other risk factors. Nineteen percent of the study participants were current hormone therapy users; 9.5% were current and 4.8% were continuous statin users. No association between continuous statin use and fractures was observed among never or past hormone therapy users (odds ratio [OR] 0.80, 95% confidence interval [CI] 0.53-1.22). In contrast, a strong protective effect (OR 0.19, 95% CI 0.04-0.87) was observed among women who concurrently used statins and hormone therapy for 1 year, independent of age; corticosteroid, bisphosphonate, thiazide diuretic, calcitonin, methotrexate, or antiepileptic drug use; chronic kidney disease; and Charlson comorbidity index. Concurrent statin use and hormone therapy may have a synergistic

Bone loss in long-term suppressive therapy with thyroid hormone

1987-01-01

The trabecular bone density of the spine was measured with CT in 31 women, aged 39-79 years, who had received an average of 13.5 years of thyroid suppressive therapy. The spinal trabecular bone density values in 24 (77%), 18 (58%), and 13 subjects (42%) were respectively below the mean for healthy age-matched controls, the fifth percentile for healthy premenopausal women, and the fifth percentile for age-matched controls. Cortical and trabecular bone loss occurs in hyperthyroidism. Although the intent is not to cause hyperthyroidism in subjects on suppressive therapy, supraphysical doses of thyroid hormone are usually necessary for suppression of thyroid-stimulating hormone. In this study, bone loss was noted in these subjects. Because most of these patients are middle-aged or postmenopausal women, who are at risk for osteoporosis, it is important to be aware of the risk of additional bone loss induced by thyroid suppressive therapy in them

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.

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.

Building a better hormone therapy?: How understanding the rapid effects of sex steroid hormones could lead to new therapeutics for age-related memory decline

Science.gov (United States)

Frick, Karyn M.

2012-01-01

A wealth of data collected in recent decades has demonstrated that ovarian sex-steroid hormones, particularly 17β-estradiol (E2), are important trophic factors that regulate the function of cognitive regions of the brain such as the hippocampus. The loss of hormone cycling at menopause is associated with cognitive decline and dementia in women, and the onset of memory decline in animal models. However, hormone therapy is not currently recommended to prevent or treat cognitive decline, in part because of its detrimental side effects. In this article, it is proposed that investigations of the rapid effects of E2 on hippocampal function be used to further the design of new drugs that mimic the beneficial effects of E2 on memory without the side effects of current therapies. A conceptual model is presented for elucidating the molecular and biochemical mechanisms through which sex-steroid hormones modulate memory, and a specific hypothesis is proposed to account for the rapid memory-enhancing effects of E2. Empirical support for this hypothesis is discussed as a means of stimulating the consideration of new directions for the development of hormone-based therapies to preserve memory function in menopausal women.

We evaluated the diagnostic capability of MRI in ovarian chocolate cysts treated by Danazol (analogue of testosterone). Both inversion recovery as T1-weighted image and long TE and TR spin echo as T2-weighted image were performed before and during hormonal therapy. Temporal change of signal intensity and size was evaluated in three ovarian chocolate cysts (stage II: 2 cases, stage III: 1 case by Beecham classification, 1966) using the 0.15-T MR system. The high intense signal from all of the cysts was seen on both T1 and T2 weighted images before treatment. There was marked decrease in size of the chocolate cysts during hormonal therapy, and they were of considerably lower signal intensity than initially on T2-weighted image. We concluded that MRI was useful to evaluate hormonal therapy for ovarian chocolate cysts. (author)

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

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.

Growth hormone deficiency (GHD) is one of the main indications for growth hormone therapy. One characteristic of this disease is bone age delay in relation to the chronological age. Pituitary dysfunction negatively affects the growth and development of the jaws and teeth of the child. The secretion of endocrine glands regulates growth, development, and gender differentiation. It also controls the growth of bones and teeth, regulates metabolism of calcium and phosphate, proteins, lipids and carbohydrates. The primary role in the endocrine system is played by the pituitary gland which is responsible for the production of somatotropin [1]. Dysfunction of the pituitary gland has a negative effect on the growth and development of long bones in the body, and may have an adverse effect on the development of maxilla, mandible and dentition of a child. There is some information in the literature that dental age is delayed in short stature children; the replacement of deciduous teeth by permanent teeth is also delayed, and newly erupted permanent teeth often require orthodontic treatment. Applying hormonal therapy positively affects the process of replacement of dentition [2, 3, 4, 5, 6]. The aim of the study was to assess bone and dental age, as well as analyze the state of dentition in children diagnosed with GH deficiency treated with growth hormone, depending on the duration of treatment. The study material consisted of 110 children (27 males, 83 females), hospitalized for somatotropin hypopituitarism in the Department of Paediatric Endocrinology and Diabetology at the Medical University of Lublin, Poland. The mean birth age was 13 years (156 months) with a standard deviation of 2 years and 6 months (30 months). 47 children (43%) started treatment with the growth hormone (group starting treatment) and 63 children (57%) whose treatment was started 2-3 years previously (group in the course of treatment). The control group consisted of 41 generally healthy children (15males

As growing of old women population, menopausal women will also increase: an accurate estimation of postmenopausal population is an essential information for health care providers considering that with aging, the incidence of all cancers is expected to increase. Hormone replacement therapy (HRT) has proven to be highly effective in alleviating menopausal symptoms such as hot flashes, night sweats, dyspareunia, sexual disorders, and insomnia and in preventing osteoporosis. According to preclinical data, estrogen and progesterone are supposed to be involved in the induction and progression of breast and endometrial cancers. Similarly, in epithelial ovarian cancer (EOC), the pathogenesis seems to be at least partly hormonally influenced. Is HRT in gynecological cancer survivors possible? The literature data are controversial. Many clinicians remain reluctant to prescribe HRT for these patients due to the fear of relapse and the risk to develop coronary heart disease or breast cancer. Before the decision to use HRT an accurate counselling should be mandatory in order to individualizing on the basis of potential risks and benefits, including a close follow-up. Nevertheless, we do believe that with strong informed consent doctors may individually consider to prescribe some course of HRT in order to minimize menopausal symptoms and disease related to hormonal reduction.

To assess the effects of adjuvant hormone therapy (AHT) on survival and disease outcome in women with epithelial ovarian cancer. Participants were premenopausal and postmenopausal women who had been diagnosed with epithelial ovarian cancer (any International Federation of Gynecology and Obstetrics stage) 9 or fewer months previously. Ineligible patients included those with deliberately preserved ovarian function, with a history of a hormone-dependent malignancy, or with any contraindications to hormone-replacement therapy. Patients were centrally randomly assigned in a 1:1 ratio to either AHT for 5 years after random assignment or no AHT (control). Main outcome measures were overall survival (OS), defined as time from random assignment to death (any cause), and relapse-free survival, defined as time from random assignment to relapse or death (any cause). Patients who continued, alive and relapse free, were censored at their last known follow-up. A total of 150 patients (n = 75, AHT; n = 75, control) were randomly assigned from 1990 to 1995 from 19 centers in the United Kingdom, Spain, and Hungary; all patients were included in intention-to-treat analyses. The median follow-up in alive patients is currently 19.1 years. Of the 75 patients with AHT, 53 (71%) have died compared with 68 (91%) of 75 patients in the control group. OS was significantly improved in patients who were receiving AHT (hazard ratio, 0.63; 95% CI, 0.44 to 0.90; P = .011). A similar effect was seen for relapse-free survival (hazard ratio, 0.67; 95% CI, 0.47 to 0.97; P = .032). Effects remained after adjustment for known prognostic factors. These results show that women who have severe menopausal symptoms after ovarian cancer treatment can safely take hormone-replacement therapy, and this may, in fact, infer benefits in terms of OS in addition to known advantages in terms of quality of life. © 2015 by American Society of Clinical Oncology.

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 (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 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.

Hormonal therapy and risk of breast cancer in mexican women.

Full Text Available The use of hormonal therapies, including hormonal contraceptives (HC and postmenopausal hormone replacement therapy (HRT have been shown to influence breast cancer (BC risk. However, the variations of these effects among populations and ethnic groups are not completely documented, especially among Hispanic women. We evaluated the association between HC and premenopausal BC risk, and between HRT and postmenopausal BC risk in Mexican women. Data from a Mexican multi-center population-based case-control study ofwomen aged 35 to 69 years were analysed. A total of 1000 cases and 1074 matched controls were recruited between 2004 and 2007. Information on hormonal therapy was collected through a structured questionnaire. Results were analysed using conditional logistic regression models. Overall, HC were used by 422/891 (47.3% premenopausal women and HRT was used by 220/1117 (19.7% postmenopausal women. For HC, odds ratios (ORs for BC were 1.11 (95% confidence interval (CI: 0.82, 1.49 for current users and 1.68 (95% CI: 0.67, 4.21 for ever-users. No clear effect of duration of use was observed. For HRT, the OR for BC was significantly increased in ever users (OR: 1.45; 95% CI: 1.01, 2.08. A non-significant increased risk was observed for combined estrogen/progestin, (OR =  1.85; 95% CI: 0.84, 4.07 whereas no effect was observed for the use of estrogen alone (OR = 1.14; 95% CI: 0.68, 1.91. Our results indicate that, HC had a non-significant effect on the risk of pre-menopausal BC, but suggested that injected contraceptives may slightly increase the risk, whereas HRT had a significant effect on post-menopausal BC in this population. This study provides new information about the effects of HC and HRT on BC risk in a Mexican population, which may be of relevance for the population of Latin America as a whole.

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.

The aim of this study is to investigate the effects of sleeve gastrectomy on hormone replacement therapy and on hypothalamic obesity in patients affected by craniopharyngioma with post-surgical pan-hypopituitarism. A retrospective review of three patients, treated for hypothalamic obesity with laparoscopic sleeve gastrectomy, who have previously undergone surgery for craniopharyngioma in their childhood, was done. Patients' mean age and BMI were 22.3 years (range 21-24) and 49.2 kg/m 2 (range 41.6-58.1), respectively. The mean time of delay between neurosurgery and bariatric surgery was 12.3 years (range 6-16). There were no major complications or deaths. At 24 months follow-up, the mean BMI was 35.3 kg/m 2 (range 31.2-40.6). No hydrocortisone and sex steroids dose changes were observed, while levothyroxine was decreased in two patients. Growth hormone replacement therapy was increased in two patients, whereas it was started in one patient. Desmopressin was significantly decreased in all of them. Patients with surgically induced pan-hypopituitarism after craniopharyngioma who become obese, can expect good results from sleeve gastrectomy: this procedure does not have significant negative effects on hormone substitution and leads to a good stabilization of body weight in a mid-term follow-up.

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.

Full Text Available OBJECTIVE: To determine the safety and efficacy of a transdermal nanostructured formulation of progesterone (10% combined with estriol (0.1% + estradiol (0.25% for relieving postmenopausal symptoms. METHODS: A total of 66 postmenopausal Brazilian women with climacteric symptoms of natural menopause received transdermal nanostructured formulations of progesterone and estrogens in the forearm daily for 60 months to mimic the normal ovarian secretory pattern. Confocal Raman spectroscopy of hormones in skin layers was performed. Clinical parameters, serum concentrations of estradiol and follicle-stimulating hormone, blood pressure, BI-RADS classification from bilateral mammography, and symptomatic relief were compared between baseline and 60 months post-treatment. Clinicaltrials.gov: NCT02033512. RESULTS: An improvement in climacteric symptoms was reported in 92.5% of women evaluated before and after 60 months of treatment. The serum concentrations of estradiol and follicle-stimulating hormone changed significantly (p<0.05 after treatment; the values of serum follicle-stimulating hormone decreased after 60 months from 82.04±4.9 to 57.12±4.1 IU/mL. A bilateral mammography assessment of the breasts revealed normal results in all women. No adverse health-related events were attributed to this hormone replacement therapy protocol. CONCLUSION: The nanostructured formulation is safe and effective in re-establishing optimal serum levels of estradiol and follicle-stimulating hormone and relieving the symptoms of menopause. This transdermal hormone replacement therapy may alleviate climacteric symptoms in postmenopausal women.

1996-01-01

To improve the effectiveness of treatment for patients with stage C prostate cancer, therapy in combination with hormonal, radiation and chemotherapy was given for the initial period, and there after, hormonal therapy was continuously administered to 18 patients with chemotherapy and three patients without it. At the Social Health Insurance Medical Center, between May 1988 and August 1991, 21 patients were diagnosed to have stage C histologically confirmed adenocarcinoma of the prostate. The average age of the patients was 69.0 years. The tumor was well, moderate and poorly differentiated in 5, 6 and 10 patients, respectively. As hormonal therapy, orchiectomy was performed on 19 of the 21 patients. Furthermore, 11 patients were administered estramustine phosphate, 9 chlormadinone acetate, and one diethylstilbesterol diphosphate. As, radiation therapy, all patients were treated with AP-PA parallel opposing technique to small pelvis with a 12 cm x 12 cm treatment field (44-45 Gy) combined with conformation radiotherapy to prostate (20-26 Gy). Chemotherapy was performed using either one or a combination of the following; cis-diamminedichloroplatinum, adriamycin, cyclophosphamide, 5-fluorouracil, methotrexate and etoposide. The observation period was 54.5 months on the average. Recurrence was observed in 3 patients, for all of which the sites were at bone. The 5-year non-recurrence rate was 90.4% by Kaplan-Meier's method. There were 4 deaths, three were due to prostate cancer and one to gastric cancer. The 5-year cumulative survival rate by Kaplan-Meier's method was 90.5%. In conclusion, this treatment was effective for stage C cases of prostate cancer. (author)

Hormone therapy and radiotherapy for early prostate cancer: A utility-adjusted number needed to treat (NNT) analysis

Jani, Ashesh B.; Kao, Johnny; Heimann, Ruth; Hellman, Samuel

2005-01-01

Purpose: To quantify, using the number needed to treat (NNT) methodology, the benefit of short-term (≤6 months) hormone therapy adjuvant to radiotherapy in the group of patients with early (clinical stage T1-T2c) prostate cancer. Methods and materials: The absolute biochemical control benefit for the use of hormones adjuvant to radiotherapy in early-stage disease was determined by literature review. A model was developed to estimate the utility-adjusted survival detriment due to the side effects of hormone therapy. The NNTs before and after the incorporation of hormone sequelae were computed; the sign and magnitude of the NNTs were used to gauge the effect of the hormones. Results: The absolute NNT analysis, based on summarizing the results of 8 reports including a total of 3652 patients, demonstrated an advantage to the addition of hormones for the general early-stage prostate cancer population as well as for all prognostic groups. After adjustment for hormone-induced functional loss, the advantage of hormones remained considerable in the high- and intermediate-risk groups, with the utility-adjusted NNT becoming weakened in the low-risk group when the utility compromise from complications of hormones was assumed to be considerable. Conclusions: Short-term hormone therapy seems to be beneficial for selected early-stage prostate cancer patients. The advantage seems to be greatest in the intermediate- and high-risk groups; with current follow-up, the side effects of hormones may outweigh their benefit in certain clinical situations in the favorable group. The present investigation demonstrates the significant role of the NNT technique for oncologic and radiotherapeutic management decisions when treatment complications need to be considered and balanced with the beneficial effects of the treatment

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  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.

2012-01-01

Bone metastases are involved in a 65-75% of advanced metastatic breast cancer cases. Tumoral markers (CEA, CA 15.3) are useful in the follow-up and evaluation of response to treatment. Hormonal therapy is the optimal treatment option in low grade metastatic breast cancer due to low toxicity and general long term good response. We present a breast cancer case treated with surgery, chemotherapy and radiotherapy. The patient was asymptomatic during the follow-up and multiple bone metastases were diagnosed as a result of an increased CA 15.3 marker found. Hormone therapy was the recommended initial treatment with good response and tolerance. Bone lesions remained stabilized for 7 years but after treatment suspension new bone lesions appeared. CA 15.3 marker had increased again. Reintroduction of hormonal therapy achieved again the stabilization of the lesions

Beyer, David C.; McKeough, Timothy; Thomas, Theresa

2005-01-01

Purpose: To review the impact of prior hormonal therapy on 10-year overall and prostate cancer specific survival after primary brachytherapy. Methods and Materials: A retrospective review was performed on the Arizona Oncology Services tumor registry for 2,378 consecutive permanent prostate brachytherapy cases from 1988 through 2001. Hormonal therapy was administered before the implant in 464 patients for downsizing of the prostate or at the discretion of the referring physician. All deceased patients with known clinical recurrence were considered to have died of prostate cancer, irrespective of the immediate cause of death. Risk groups were defined, with 1,135 favorable (prostate-specific antigen [PSA] 70 years (p = 0.0013), Gleason score ≥ 7 (p = 0.0005), and prior hormone use (p = 0.0065) on overall survival. Conclusions: At 10 years, in prostate cancer patients receiving brachytherapy, overall survival is worse in men receiving neoadjuvant hormonal therapy, compared with hormone naive patients. This does not appear to be due to other known risk factors for survival (i.e., stage, grade, PSA, age) on multivariate analysis. The leading causes of death were cardiovascular, prostate cancer, and other cancers with no obvious discrepancy between the two groups. This finding is unexpected and requires confirmation from other centers

Estrogen, vascular estrogen receptor and hormone therapy in postmenopausal vascular disease.

Science.gov (United States)

Khalil, Raouf A

2013-12-15

Cardiovascular disease (CVD) is less common in premenopausal women than men of the same age or postmenopausal women, suggesting vascular benefits of estrogen. Estrogen activates estrogen receptors ERα, ERβ and GPR30 in endothelium and vascular smooth muscle (VSM), which trigger downstream signaling pathways and lead to genomic and non-genomic vascular effects such as vasodilation, decreased VSM contraction and growth and reduced vascular remodeling. However, randomized clinical trials (RCTs), such as the Women's Health Initiative (WHI) and Heart and Estrogen/progestin Replacement Study (HERS), have shown little vascular benefits and even adverse events with menopausal hormone therapy (MHT), likely due to factors related to the MHT used, ER profile, and RCT design. Some MHT forms, dose, combinations or route of administration may have inadequate vascular effects. Age-related changes in ER amount, distribution, integrity and post-ER signaling could alter the vascular response to MHT. The subject's age, preexisting CVD, and hormone environment could also reduce the effects of MHT. Further evaluation of natural and synthetic estrogens, phytoestrogens, and selective estrogen-receptor modulators (SERMs), and the design of appropriate MHT combinations, dose, route and 'timing' could improve the effectiveness of conventional MHT and provide alternative therapies in the peri-menopausal period. Targeting ER using specific ER agonists, localized MHT delivery, and activation of specific post-ER signaling pathways could counter age-related changes in ER. Examination of the hormone environment and conditions associated with hormone imbalance such as polycystic ovary syndrome may reveal the causes of abnormal hormone-receptor interactions. Consideration of these factors in new RCTs such as the Kronos Early Estrogen Prevention Study (KEEPS) could enhance the vascular benefits of estrogen in postmenopausal CVD.

Full Text Available Objective: To discuss the effect of adjuvant levosimendan therapy on neuroendocrine hormones and cytokines in elderly patients with chronic heart failure. Methods: A total of 100 elderly patients with chronic heart failure who were treated in the hospital between March 2014 and March 2017 were divided into control group and levosimendan group by random number table, each with 50 cases. Control group received clinical routine therapy for chronic heart failure, and levosimendan group received routine therapy combined with adjuvant levosimendan therapy. The differences in serum levels of RAAS indexes, thyroid hormones, myocardial damage indexes and endothelial function indexes were compared between the two groups before and after treatment. Results: At T0, there was no statistically significant difference in serum levels of RAAS indexes, thyroid hormones, myocardial damage indexes and endothelial function indexes between the two groups. At T1, serum RAAS indexes PRA, AngⅡ and ALD levels of levosimendan group were lower than those of control group; serum thyroid hormones TT3, TT4, FT3 and FT4 levels of levosimendan group were higher than those of control group; serum myocardial damage indexes cTnⅠ, H-FABP and NT-proBNP levels of levosimendan group were lower than those of control group; serum endothelial function index NO level of levosimendan group was higher than that of control group while ET-1 level was lower than that of control group. Conclusion: Adjuvant levosimendan therapy for elderly patients with chronic heart failure can effectively adjust the secretion of neuroendocrine hormones and reduce the myocardial and vascular endothelial damage.

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

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

Jung, Min-Ho

2017-09-01

The purpose of this study was to illustrate the effects of growth hormone (GH) therapy and fixed functional appliance treatment in a 13-year-old Class II malocclusion patient without GH deficiency. GH has been shown to effectively increase endochondral growth and induce a more prognathic skeletal pattern. Although a major concern in Class II retrognathic patients is chin deficiency, long-term studies have shown that the mandibular growth enhancement effects of functional appliances are clinically insignificant. This case report demonstrates that the mandible grew significantly during fixed functional appliance treatment combined with GH therapy, with stable results during 2 years 11 months of retention. More studies are needed to evaluate GH therapy as a supplement in Class II treatment. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

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

Sheanon, Nicole M; Backeljauw, Philippe F

2015-01-01

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.

The effects of growth hormone deficiency and growth hormone replacement therapy on intellectual ability, personality and adjustment in children.

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.

Slipped Capital Femoral Epiphysis as a Complication of Growth Hormone Therapy

Directory of Open Access Journals (Sweden)

Shuo-Yu Wang

2007-01-01

Full Text Available Slipped capital femoral epiphysis (SCFE is a rare complication of growth hormone (GH therapy. Here, we report three patients who developed SCFE during GH therapy. The first two patients had hypopituitarism and had started GH therapy at the age of 15 years 6 months and 13 years 9 months, respectively. SCFE developed 4 years and 1 year after GH therapy, respectively. The third patient had Prader-Willi syndrome with obesity and hypogonadism and began GH therapy at the age of 12 years and 11 months. SCFE developed 2 months after starting GH therapy. Pain over the hip joints or over the knees is an early sign of SCFE. Despite recommendation, none of the three patients continued GH therapy. A high index of suspicion during GH therapy in patients at high risk of SCFE is important for early diagnosis and appropriate management. [J Formos Med Assoc 2007;106(2 Suppl:S46-S50

Endocrinology and hormone therapy in breast cancer: Endocrine therapy in premenopausal women

International Nuclear Information System (INIS)

Pritchard, Kathleen

2005-01-01

Endocrine therapy remains important in premenopausal women with hormone receptor positive breast cancer. Ovarian ablation, used alone, is effective in delaying recurrence and increasing survival in such women. When added to chemotherapy, it is less clear that it is effective perhaps because of the endocrine ablative effect of chemotherapy. Trials comparing ovarian ablation with or without tamoxifen to CMF-type chemotherapy suggest that the endocrine therapy is equivalent to or better than this chemotherapy in women whose tumors have estrogen and/or progesterone receptor. Tamoxifen is also effective in preventing recurrence and prolonging survival in the adjuvant setting in premenopausal women. While most of the available data deals with tamoxifen given alone, it appears to have a similar beneficial effect when added to chemotherapy in the premenopausal adjuvant setting. Adjuvant aromatase inhibitors should not be used in premenopausal women

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 (Porgans per donor and group B provided a mean of 2.87 organs per donor, an increase of 15.3% in group A (Pdonor 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.

There is an increasing body of literature showing associations of organochlorine exposure with risk of diabetes and insulin resistance. Some studies suggest that associations differ by gender and that diabetes risk, in turn, may be affected by endogenous steroid hormones. This report examines the relationships of serum PCBs and endogenous hormones with history of diabetes in a cohort of persons previously employed at a capacitor manufacturing plant. A total of 118 women were post-menopausal with complete data, of whom 93 were not using steroid hormones in 1996, at the time of examination, which included a survey of exposure and medical history, height, weight and collection of blood and urine for measurements of lipids, liver function, hematologic markers and endogenous hormones. This analysis examines relationships of serum polychlorinated biphenyls (PCBs), work exposure and endogenous hormones with self-reported history of diabetes after control for potential confounders. All PCB exposure groups were significantly related to history of diabetes, but not to insulin resistance as measured by the homeostatic model assessment of insulin resistance (HOMA-IR) in non-diabetics. Diabetes was also independently and inversely associated with follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEAS) and triiodothyronine (T3) uptake. HOMA-IR was positively associated with body mass index (BMI) and C-reactive protein (CRP) and inversely associated with sex hormone binding globulin (SHBG) and T3 uptake after control for PCB exposure. Possible biologic mechanisms are discussed. This study confirms previous reports relating PCB exposure to diabetes and suggests possible hormonal pathways deserving further exploration.

Primary prevention of cardiovascular disease with hormone replacement therapy

DEFF Research Database (Denmark)

Schierbeck, L

2015-01-01

Many peri- and postmenopausal women suffer from a reduced quality of life due to menopausal symptoms and preventable diseases. The importance of cardiovascular disease in women must be emphasized, as it is the leading cause of mortality and morbidity in women. It is well known that female hormones...... contribute to the later onset of cardiovascular disease in women. The effect of estrogens has for decades been understood from observational studies of postmenopausal women treated with hormone replacement therapy (HRT). Later, treatment with HRT was disregarded due to the fear of side......-effects and an ambiguity of the cardiovascular advantages. Accumulating knowledge from the large number of trials and studies has elucidated the cause for the disparity in results. In this paper, the beneficial effects of HRT, with emphasis on cardiovascular disease are explained, and the relative and absolute risks...

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.

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.

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.

Hypopituitarism can be caused by radiation therapy, even when it is not directly applied on the hypothalamic-pituitary axis, and can lead to anterior pituitary deficiency mainly due to hypothalamic damage. The progressive loss of the anterior pituitary hormones usually occurs in the following order: growth hormone, gonadotropin hormones, adrenocorticotropic hormone and thyroid-stimulating hormone. Although there are several different tests available to confirm anterior pituitary deficiency, this paper will focus on the gold standard tests for patients submitted to radiation therapy. We emphasize that the decline of anterior pituitary function is time- and dose-dependent with some variability among the different axes. Therefore, awareness of the need of a joint management by endocrinologists and oncologists is essential to improve treatment and quality of life of the patients. (author)

Adjuvant endocrine therapy for premenopausal women with hormone-responsive breast cancer.

Science.gov (United States)

Mathew, Aju; Davidson, Nancy E

2015-11-01

Multiple strategies for endocrine treatment of premenopausal women with hormone-responsive breast cancer have been assessed and results have been presented over the last two years. These include tamoxifen for 5-10 years (ATLAS and aTTom), tamoxifen for 5 years followed by aromatase inhibitor (AI) for 5 years for women who have become postmenopausal (MA-17); ovarian ablation (OA) by surgery (EBCTCG overview); ovarian function suppression (OFS) by LHRH agonist (LHRH agonist meta-analysis); or combinations of approaches including OFS plus tamoxifen or AI (SOFT, TEXT, ABCSG 12 and E3193). Many of these trials have taken place in the backdrop of (neo)adjuvant chemotherapy which can confound interpretation because such therapy can suppress ovarian function either transiently or permanently. Nonetheless these trials suggest in aggregate that 10 years of tamoxifen are better than 5 years and that a program of extended adjuvant therapy of tamoxifen for 5 years followed by aromatase inhibitor for 5 years is effective for suitable candidates. The SOFT and E3193 trials do not show a major advantage for use of OFS + tamoxifen compared to tamoxifen alone. The joint SOFT/TEXT analysis and ABCGS12 trials both suggest that outcomes can be excellent with the use of combined endocrine therapy alone in properly selected patients but give conflicting results with regard to potential benefits for OFS + AI compared with OFS + tamoxifen. Further work will be needed to ascertain long-term outcomes, identify factors that predict who will benefit from extended adjuvant endocrine therapy, and assess role of OFS by medical or surgical means. It is clear, however, that endocrine therapy is a critical part of the adjuvant regimen for most premenopausal women with hormone-responsive breast cancer, and a subset of these women with luminal A-type tumors can be safely treated with endocrine therapy alone.

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.

2015-01-01

Acne vulgaris is a very common condition affecting up of 93% of adolescents. Although rare, this disease may persist in adulthood. In adult women with acne (those older than 25 years old), this condition is particularly relevant because of the refractory to conventional therapies, which makes acne a challenge for dermatologists in this group of patients. In order to its potential risk for chronicity and the involvement of visible anatomical sites such as face and upper torso, acne has been associated with a wide spectrum of psychological and social dysfunction such as depression, anxiety, suicidal ideation, somatization, and social inhibition. In particular, adult women with acne have been shown to be adversely impacted by the effect of acne on their quality of life. For the last four decades, dermatologists have used hormonal therapies for the management of acne vulgaris in adult women, which are considered a rational choice given the severity and chronicity of this condition in this group of patients. The aim of this work is to review the hormonal drugs for management of acne. © 2015 Wiley Periodicals, Inc.

The aim of this study was to analyze the effects of hormone therapy (HT) on postural balance in postmenopausal women and its association with risk of falls. In this cross-sectional study, a total of 225 Brazilian postmenopausal women aged 45 to 75 years were included and divided into two groups: HT users (n = 102) and nonusers (n = 123). HT users were women who had continuously taken HT throughout the preceding 6 months, whereas nonusers received no such therapy during the same period. Women with amenorrhea for more than 12 months and aged 45 years or older were included. Those with neurological or musculoskeletal disorders, vestibulopathies, uncorrected visual deficit, or drug use that could affect balance were excluded. Histories of falls (previous 24 mo) as well as clinical and anthropometric characteristics were analyzed. Postural balance was assessed through stabilometry (computerized force platform), Romberg test, and crouching test. Statistical analysis included the median test, χ test, Spearman correlation coefficient, and logistic regression method (odds ratio). Women users of HT were younger (53.0 vs 57.0 y) and with a shorter time since menopause (5.5 vs 10.0 y) than nonusers (P Romberg test and fall rate (P > 0.05). In the crouching test, 47.1% of the participants showed an adequate level of muscle strength in lower limbs without differences between the groups (P > 0.05). Postmenopausal women using HT showed lower frequency of falls and a better performance in stabilometric parameters than did nonusers.

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.

Risks and benefits of hormone therapy: has medical dogma now been overturned?

In an integrated overview of the benefits and risks of menopausal hormone therapy (HT), the Women's Health Initiative (WHI) investigators have claimed that their 'findings … do not support use of this therapy for chronic disease prevention'. In an accompanying editorial, it was claimed that 'the WHI overturned medical dogma regarding menopausal [HT]'. To evaluate those claims. Epidemiological criteria of causation were applied to the evidence. A 'global index' purporting to summarize the overall benefit versus the risk of HT was not valid, and it was biased. For coronary heart disease, an increased risk in users of estrogen plus progestogen (E + P), previously reported by the WHI, was not confirmed. The WHI study did not establish that E+ P increases the risk of breast cancer; the findings suggest that unopposed estrogen therapy (ET) does not increase the risk, and may even reduce it. The findings for stroke and pulmonary embolism were compatible with an increased risk, and among E+ P users there were credible reductions in the risk of colorectal and endometrial cancer. For E+ P and ET users, there were credible reductions in the risk of hip fracture. Under 'worst case' and 'best case' assumptions, the changes in the incidence of the outcomes attributable to HT were minor. Over-interpretation and misrepresentation of the WHI findings have damaged the health and well-being of menopausal women by convincing them and their health professionals that the risks of HT outweigh the benefits.

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.

Full text: 131 I therapy may cause exacerbation of hyperthyroidism due to leakage of previously formed thyroid hormones from damaged thyroid cells in Graves' patients. To avoid this complication pretreatment with antithyroid drugs is recommended. Otherwise, the use of antithyroid drugs prior to 131 I therapy may diminish the success of 131 I therapy and should therefore be discontinued. The aim of our prospective clinical study was to compare early changes of thyroid hormone concentrations after 131 I therapy in Graves' patients, pretreated or not pretreated with methimazole. 92 consecutive Graves' patients, 84 females and 8 males, aged 17 to 80 were treated with 555 MBq of 131 I. Absorbed dose of 131 I was calculated. In the first group of 22 patients treatment with methimazole (20 mg/day) was discontinued 7 days before 131 I therapy, the second group of 33 patients received methimazole until the day of 131 I therapy and the third group of 37 patients was not pretreated with methimazole before 131 I therapy. 7 and 2 days before 131 I therapy and 2, 5, 12 and 30 days after serum free T 4 (fT 4 ) and free T 3 (fT 3 ) concentrations were measured. In the first group a significant increase of fT 4 and fT 3 was observed 7 days after discontinuation of methimazole (fT 4 14.60 ± 4.10 vs. 18.25 ± 7.16; fT 3 5.45 ± 1.44 vs. 7.79 ± 5.27 pmol/l), while gradual decrease of fT 4 and fT 3 was observed after 131 I therapy. In the second group a significant increase of fT 4 and fT 3 after 131 I therapy peaking on day 5 was observed (fT 4 20.91 ± 13.70 vs. 27.85 ± 18.17; fT 3 7.81 ± 5.21 vs. 9.42 ± 6.21 pmol/l). In the third group significant decrease of fT 4 and fT 3 concentrations was observed after 131 I therapy (fT 4 36.12 ± 18.55 vs. on day 12th 27.49 ± 15.20; fT 3 12.66 ± 7.04 vs. on day 12th 8.31 ± 4.92 pmol/l). No correlation between absorbed dose of 131 I and changes of fT 4 and fT 3 concentrations was observed. Therefore, our results indicate that not 131 I

2003-01-01

Background and purpose:To determine the effect of curative radiation therapy (46-50 Gy) on the sex hormone levels in male rectal cancer patients. Materials and methods:Twenty-five male rectal cancer patients (mean age 65 years), receiving pelvic radiation therapy (2 Gyx23-25 fractions in 5 weeks) were included. Serum testosterone, FSH and LH were determined before start of treatment, at the 10th and 25th fractions, and 4-6 weeks after completed radiotherapy. The testicular dose was determined by thermoluminescent dosimetry. Results:Five weeks of radiation therapy (46-50 Gy) resulted in a 100% increase in serum FSH, a 70% increase in LH, and a 25% reduction in testosterone levels. After treatment, 35% of the patients had serum testosterone levels below lower limit of reference. The mean radiation dose to the testicles was 8.4 Gy. A reduction in testosterone values was observed already after a mean dose of 3.3 Gy (10th fraction). Conclusion:Radiation therapy (46-50 Gy) for rectal cancer resulted in a significant increase in serum FSH and LH and a significant decrease in testosterone levels, indicating that sex hormone production is sensitive to radiation exposure in patients with a mean age of 65 years

Results of radiation therapy combined with neoadjuvant hormonal therapy for stage III prostate cancer. Comparison of two different definitions of PSA failure

We herein report the clinical outcome of radical radiation therapy combined with neoadjuvant hormonal therapy (NHT) for stage III (International Union Against Cancer [UICC] 1997: UICC 97) prostate cancer. Prostate-specific antigen (PSA) failure-free survival was assessed according to two different definitions, and the appropriateness of each definition is discussed. Between October 1997 and December 2000, 27 patients with stage III prostate cancer were enrolled in this study. The median pretreatment PSA level was 29 ng/ml (range, 7.4-430 ng/ml). The Gleason score (GS) was 7 or more in 22 patients (81%). All patients received 3 months of NHT with a luteinizing hormone-releasing hormone (LH-RH) analogue, in combination with an antiandrogen (flutamide), given during the first 2 weeks, followed by 70-Gy external-beam radiation therapy (EBRT) in 35 fractions. The initial 46 Gy was given with a four-field technique, while the remainder was given with a dynamic conformal technique. No adjuvant hormonal therapy (AHT) was given. The median follow-up time was 63 months. PSA levels decreased to the normal range (<4 ng/ml) after irradiation in all but one patient. The 5-year PSA failure-free survival was 34.8% according to the American Society for Therapeutic Radiology and Oncology (ASTRO) definition and it was 43.0% according to the ''nadir plus 2'' definition. Discordance of the results between the two definitions was seen in two patients. The 5-year overall and cause-specific survivals were 83.0% and 93.3%, respectively. No severe acute or late adverse effects were observed. Seventy Gy of EBRT following 3 months of NHT produced therapeutic results comparable to those reported in other studies which used long-term AHT. The value of long-term AHT for Japanese men should be tested in a clinical trial. (author)

Growth hormone therapy in a girl with Turner syndrome and diabetes type 1 - case report.

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.

Full Text Available Nathan W Kopper, Jennifer Gudeman, Daniel J ThompsonKV Pharmaceutical, St. Louis, MO, USAAbstract: Vasomotor symptoms (VMS associated with menopause can cause significant discomfort and decrease the quality of life for women in the peri-menopausal and post-menopausal stages of life. Hormone therapy (HT is the mainstay of treatment for menopausal symptoms and is currently the only therapy proven effective for VMS. Numerous HT options are available to treat VMS, including estrogen-only and estrogen-progestogen combination products to meet the needs of both hysterectomized and nonhysterectomized women. In addition to selecting an appropriate estrogen or estrogen-progestogen combination, consideration should be given to the route of administration to best suit the needs of the patient. Delivery systems for hormone therapy include oral tablets, transdermal patches, transdermal topical (nonpatch products, and intravaginal preparations. Oral is currently the most commonly utilized route of administration in the United States. However, evidence suggests that oral delivery may lead to some undesirable physiologic effects caused by significant gut and hepatic metabolism. Transdermal drug delivery may mitigate some of these effects by avoiding gut and hepatic first-pass metabolism. Advantages of transdermal delivery include the ability to administer unmetabolized estradiol directly to the blood stream, administration of lower doses compared to oral products, and minimal stimulation of hepatic protein production. Several estradiol transdermal delivery technologies are available, including various types of patches, topical gels, and a transdermal spray.Keywords: estradiol, hormone therapy, menopause, transdermal drug delivery, vasomotor symptoms

Prader-Willi syndrome (PWS) is a genetic disorder frequently characterized by obesity, growth hormone deficiency, genital abnormalities, and hypogonadotropic hypogonadism. Incomplete or delayed pubertal development as well as premature adrenarche are usually found in PWS, whereas central precocious puberty (CPP) is very rare. This study aimed to report the clinical and biochemical follow-up of a PWS boy with CPP and to discuss the management of pubertal growth. By the age of 6, he had obesity, short stature, and many clinical criteria of PWS diagnosis, which was confirmed by DNA methylation test. Therapy with recombinant human growth hormone (rhGH) replacement (0.15 IU/kg/day) was started. Later, he presented psychomotor agitation, aggressive behavior, and increased testicular volume. Laboratory analyses were consistent with the diagnosis of CPP (gonadorelin-stimulated LH peak 15.8 IU/L, testosterone 54.7 ng/dL). The patient was then treated with gonadotropin-releasing hormone analog (GnRHa). Hypothalamic dysfunctions have been implicated in hormonal disturbances related to pubertal development, but no morphologic abnormalities were detected in the present case. Additional methylation analysis (MS-MLPA) of the chromosome 15q11 locus confirmed PWS diagnosis. We presented the fifth case of CPP in a genetically-confirmed PWS male. Combined therapy with GnRHa and rhGH may be beneficial in this rare condition of precocious pubertal development in PWS.

BACKGROUND: In 1975, estrogen only was found to be associated with an increased risk of endometrial cancer. In November 2015, NICE guidelines on hormone therapy were published that did not take this risk into account. AIM: This systematic literature review assesses the safety of estrogen plus...... progestin therapy according to the risk of endometrial cancer, while considering both regimen and type of progestin. METHODS: PubMed, EMBASE and the Cochrane Library were searched, resulting in the identification of 527 published articles on menopausal women with intact uteri treated with estrogen only......, estrogen plus progestin or tibolone for a minimum of one year. Risk of endometrial cancer was compared to placebo or never users and measured as relative risk, hazard or odds ratio. RESULTS: 28 studies were included. The observational literature found an increased risk among users of estrogen alone...

• 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.

2017-07-01

The 2017 Hormone Therapy Position Statement of The North American Menopause Society (NAMS) updates the 2012 Hormone Therapy Position Statement of The North American Menopause Society and identifies future research needs. An Advisory Panel of clinicians and researchers expert in the field of women's health and menopause was recruited by NAMS to review the 2012 Position Statement, evaluate new literature, assess the evidence, and reach consensus on recommendations, using the level of evidence to identify the strength of recommendations and the quality of the evidence. The Panel's recommendations were reviewed and approved by the NAMS Board of Trustees.Hormone therapy (HT) remains the most effective treatment for vasomotor symptoms (VMS) and the genitourinary syndrome of menopause (GSM) and has been shown to prevent bone loss and fracture. The risks of HT differ depending on type, dose, duration of use, route of administration, timing of initiation, and whether a progestogen is used. Treatment should be individualized to identify the most appropriate HT type, dose, formulation, route of administration, and duration of use, using the best available evidence to maximize benefits and minimize risks, with periodic reevaluation of the benefits and risks of continuing or discontinuing HT.For women aged younger than 60 years or who are within 10 years of menopause onset and have no contraindications, the benefit-risk ratio is most favorable for treatment of bothersome VMS and for those at elevated risk for bone loss or fracture. For women who initiate HT more than 10 or 20 years from menopause onset or are aged 60 years or older, the benefit-risk ratio appears less favorable because of the greater absolute risks of coronary heart disease, stroke, venous thromboembolism, and dementia. Longer durations of therapy should be for documented indications such as persistent VMS or bone loss, with shared decision making and periodic reevaluation. For bothersome GSM symptoms not

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 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.

Health care factors associated with survival among women with breast cancer on hormone therapy in Rio de Janeiro, Brazil, 2004 – 2010

Directory of Open Access Journals (Sweden)

Cláudia de Brito

Full Text Available ABSTRACT Objectives To better understand the role that health care plays in breast cancer survival by investigating the effects that hormone therapy adherence and other select health care variables, adjusted for clinical and sociodemographic factors, had among a population of women in Rio de Janeiro, Brazil. Methods This was a longitudinal study based on secondary data of 5 861 women treated with hormone therapy (tamoxifen or aromatase inhibitors at the National Cancer Institute of Brazil (INCA, from 1 January 2004 – 29 October 2010. Four different sources of data were integrated for analysis: INCA Pharmacy Sector Dispensation System; Hospital-based Cancer Registry; Integrated Hospital System and INCA Absolute System; and Mortality Information System. Analyses explored the effects of adherence to hormone therapy, disease care aspects, and sociodemographic, behavioral, and clinical variables, on the time of survival, using Kaplan-Meier and Cox proportional hazards models. Results The general survival rate was 94% in the first year after initiation of hormone therapy, and 71% in the fifth year. The Cox model indicated a higher hazard of death among women smokers, with more hospitalizations, more exams, and, among those who used, who used only aromatase inhibitors, as hormone therapy modality. The hazard was lower among women with a partner (stable relationship, a high school or college education a family history of cancer, and those who were treated by a mastologist, oncologist, and/or psychotherapist, who underwent surgery, and who adhered to hormone therapy. Conclusions The study indicated more vulnerable sub-groups and the aspects of care that provide best results, bringing new knowledge to improve assistance to this group of women.

Purpose: To determine the incidence of and risk factors for radiation pneumonitis (RP) after stereotactic ablative radiation therapy (SABR) to the lung in patients who had previously undergone conventional thoracic radiation therapy. Methods and Materials: Seventy-two patients who had previously received conventionally fractionated radiation therapy to the thorax were treated with SABR (50 Gy in 4 fractions) for recurrent disease or secondary parenchymal lung cancer (T 10 and mean lung dose (MLD) of the previous plan and the V 10 -V 40 and MLD of the composite plan were also related to RP. Multivariate analysis revealed that ECOG PS scores of 2-3 before SABR (P=.009), FEV1 ≤65% before SABR (P=.012), V 20 ≥30% of the composite plan (P=.021), and an initial PTV in the bilateral mediastinum (P=.025) were all associated with RP. Conclusions: We found that severe RP was relatively common, occurring in 20.8% of patients, and could be predicted by an ECOG PS score of 2-3, an FEV1 ≤65%, a previous PTV spanning the bilateral mediastinum, and V 20 ≥30% on composite (previous RT+SABR) plans. Prospective studies are needed to validate these predictors and the scoring system on which they are based.

Objective. The diagnostic significance of an enlarged pituitary gland regarding both shape and size parameters on MR imaging has previously been demonstrated in children with central precocious puberty. This study was designed to assess changes in these parameters following successful suppressive therapy of central precocious puberty with the gonadotropin-releasing hormone (GnRH) analogue. Materials and methods. Twelve girls (mean age 7.3 years) with central precocious puberty were prospectively enrolled in our study protocol. Sagittal and coronal MR images of the pituitary region were obtained in all patients before treatment and after at least 6 months of GnRH analogue therapy (mean 18.0 months). Parameters measured included pituitary gland height, length, width, sagittal cross-sectional area, and volume. Results. All patients had excellent clinical response to treatment with arrest of secondary sexual development, normalization of serum estradiol levels, and complete obliteration of the LH response to diagnostic GnRH stimulation. No significant change occurred in any pituitary size or shape parameter following GnRH analogue therapy. Conclusion. Favorable clinical response to GnRH analogue therapy in central precocious puberty is not accompanied by significant a change in pituitary gland size and shape. (orig.)

Full Text Available Adult growth hormone deficiency (AGHD is being recognized increasingly and has been thought to be associated with premature mortality. Pituitary tumors are the commonest cause for AGHD. Growth hormone deficiency (GHD has been associated with neuropsychiatric-cognitive, cardiovascular, neuromuscular, metabolic, and skeletal abnormalities. Most of these can be reversed with growth hormone therapy. The insulin tolerance test still remains the gold standard dynamic test to diagnose AGHD. Growth hormone is administered subcutaneously once a day, titrated to clinical symptoms, signs and IGF-1 (insulin like growth factor-1. It is generally well tolerated at the low-doses used in adults. Pegylated human growth hormone therapy is on the horizon, with a convenient once a week dosing.

The hormone levels were measured before and after hormonal therapy. Statistically significant changes in the levels of the hormones in this study were recognized (p<0,001) as a result of treatment with estrogen preparations. Plasma prolactin was raised before estrogen therapy (statistically significant rise, p<0,001), as compared to the levels in a control group of normal subjects. A mild tendency was observed toward its increase, depending on the duration of treatment. The results of this study show that control of the hormonal status of patients with prostate cancer may serve as reliable criterion in evaluating the effectiveness of hormonal therapy. The changes in prolactin levels are evidence of hormonal disbalance, which may be observed in these patients

Background 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. Methods 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. Results 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 nine years of EHT use, but after only three years of CHT use. Discussion 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. Impact 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.

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.

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

Background: This study analyzed the outcome of salvage radiotherapy for biochemical failure after radical prostatectomy (RP). By comparing the outcomes for patients who received RT alone and for those who received combined RT and hormonal therapy, we assessed the potential benefits of hormonal therapy. Patients and Methods: This cohort was comprised of 101 patients who received salvage RT between 1990 and 2001 for biochemical failure after RP. Fifty-nine of these patients also received hormone. Margin status (positive vs. negative), extracapsular extension (yes vs. no), seminal vesicle involvement (yes vs. no), pathologic stage, Gleason score, pre-RP PSA, post-RP PSA, pre-RT PSA, hormonal use, radiotherapy dose and technique, RP at M. D. Anderson Cancer Center, and time from RP to salvage RT were analyzed. Statistically significant variables were used to construct prognostic groups. Results: Independent prognostic factors for the RT-alone group were margin status and pre-RT PSA. RP at M. D. Anderson Cancer Center was marginally significant (p = 0.06) in multivariate analysis. Pre-RT PSA was the only significant prognostic factor for the combined-therapy group. We used a combination of margin status and pre-RT PSA to construct a prognostic model for response to the salvage treatment based on the RT group. We identified the favorable group as those patients with positive margin and pre-RT PSA ≤0.5 ng/mL vs. the unfavorable group as otherwise. This stratification separates patients into clinically meaningful groups. The 5-year PSA control probabilities for the favorable vs. the unfavorable group were 83.7% vs. 61.7% with radiotherapy alone (p = 0.03). Androgen ablation seemed to be most beneficial in the unfavorable group. Conclusion: After prostatectomy, favorable-group patients may fare well with salvage radiotherapy alone. These patients may be spared the toxicity of androgen ablation. The other patients may benefit most from a combined approach with hormonal

Full Text Available Abstract Background For postmenopausal women, the main reason to start hormone therapy (HT is to reduce menopausal symptoms and to improve quality of life (QOL. The aim of this study was to analyse the impact of HT on different aspects of symptom experience and QOL during a randomised trial. A total of 1823 postmenopausal women were recruited into the Estonian Postmenopausal Hormone Therapy (EPHT trial in 1999–2001. Women were randomised to blind HT, open-label HT, placebo or non-treatment arm. After one year in the trial, a questionnaire was mailed and 1359 women (75% responded, 686 in the HT arms and 673 in the non-HT arms. Mean age at filling in the questionnaire was 59.8 years. The questionnaire included Women's Health Questionnaire (WHQ to assess menopause specific QOL of middle-aged women together with a 17-item questionnaire on symptoms related to menopause, a question about painful intercourse, and a question about women's self-rated health. Results After one year in the trial, fewer women in the HT arms reported hot flashes, trouble sleeping, and sweating on the symptom questionnaire. According to WHQ, women in the HT arms had fewer vasomotor symptoms, sleep problems, and problems with sexual behaviour, but more menstrual symptoms; HT had no effect on depression, somatic symptoms, memory, attractiveness, or anxiety. A smaller proportion of women reported painful intercourse in the HT arms. There were no significant differences between the trial arms in women’s self-rated subjective health. Conclusions The results from the EPHT trial confirm that HT is not justified for treating symptoms, other than vasomotor symptoms, among postmenopausal women. WHQ proved to be a useful and sensitive tool to assess QOL in this age group of women.

Full Text Available Variability in the severity of asthma during various phases of the menstrual cycle has been frequently suspected. However, the hormonal changes that might affect mediators of bronchospasm have yet to be elucidated. The case of a 41-year-old woman suffering from longstanding asthma with life-threatening exacerbations is reported. The patient was treated with buserelin, a gonadotropin releasing hormone (GnRH analogue, which created a temporary chemical menopause and thus permitted diagnosis of a premenstrual exacerbation of asthma and offered insight into potential therapy. GnRH analogues may therefore be of value in assessing women with severe asthma suspected to vary with the menstrual cycle. The addition of estrogens and progestins at the same time as treatment with GnRH analogue may be of value in determining the role of these hormones in the pathogenesis of menstrually related exacerbations of asthma.

Full Text Available Marianna Cannoletta, Angelo Cagnacci Institute of Obstetrics and Gynecology, Department of Medical and Surgical Sciences of the Mother, Child and Adult, University of Modena and Reggio Emilia, Modena and Reggio Emilia, Emilia-Romagna, Italy Abstract: The rate of hypertension increases after menopause. Whether estrogen and progesterone deficiency associated with menopause play a role in determining a worst blood pressure (BP control is still controversial. Also, studies dealing with the administration of estrogens or hormone therapy (HT have reported conflicting evidence. In general it seems that, despite some negative data on subgroups of later postmenopausal women obtained with oral estrogens, in particular conjugated equine estrogens (CEE, most of the data indicate neutral or beneficial effects of estrogen or HT administration on BP control of both normotensive and hypertensive women. Data obtained with ambulatory BP monitoring and with transdermal estrogens are more convincing and concordant in defining positive effect on BP control of both normotensive and hypertensive postmenopausal women. Overall progestin adjunct does not hamper the effect of estrogens. Among progestins, drospirenone, a spironolactone-derived molecule, appears to be the molecule with the best antihypertensive properties.

OBJECTIVE: Few studies have examined the risk of an ovarian serous borderline tumor (SBT) associated with parity, infertility, oral contraceptives (OCs), or hormone replacement therapy (HRT), which was the study aim. METHODS: This nationwide case-control study included all women with an SBT...... diagnosis in Denmark, 1978-2002. SBTs were confirmed by centralized expert pathology review. For each case, 15 age-matched female controls were randomly selected using risk-set sampling. Cases and controls with previous cancer (except for non-melanoma skin cancer) and controls with bilateral oophorectomy...... or salpingo-oophorectomy were excluded. Conditional logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: We found a strongly decreased risk of SBTs among parous women which decreased with increasing number of children (p

We conducted a retrospective analysis of the clinical activity of fulvestrant in postmenopausal women with hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (MBC) previously treated with endocrine therapy and/or chemotherapy. We reviewed the medical records of all patients with MBC treated at Samsung Medical Center between January 2009 and August 2016. Patients received fulvestrant 250 mg intramuscularly every 28 days (from January 2009 to November 2010) or 500 mg intramuscularly every 28 days (from December 2010 to August 2016). Tumor responses were assessed every 8 weeks and at the end of treatment, as well as when disease progression was suspected. A total of 84 patients were included in this study. A median of two previous endocrine treatments had been performed; 79% of the patients had received two or more endocrine treatments. Forty-five patients (54%) had been treated with chemotherapy for MBC before the fulvestrant treatment course. Visceral metastasis was found in 49 patients (58%). The estimated median progression-free survival and overall survival were 4.4 months (95% confidence interval [CI], 3.4 to 5.5) and 32.5 months (95% CI, 17.6 to 47.4), respectively. The disease control rate was 40.5% (95% CI, 30.5 to 51.5); partial response was observed in 16% of the patients and stable disease was observed in 25% of the patients. The most frequently reported adverse reactions were mild-to-moderate grade myalgia (10.5% of the patients), injection site pain (7%), and fatigue (7%). Fulvestrant was generally well tolerated. Fulvestrant showed encouraging clinical activity and favorable feasibility in postmenopausal women with MBC who had been treated with multiple endocrine therapies and/or cytotoxic chemotherapies.

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.

Objective: To investigate the effects of recombinant human growth hormone (rhGH) on metabolic parameters in patients with craniopharyngioma surgeries. Methods: Totallys 30 patients with craniopharyngioma were included in this retrospective study. They were divided into growth hormone (GH) group and control group according to whether they received rhGH therapy or not. The following parameters, including body mass index (BMI), weight, waist circumstance, transaminase, fasting blood glucose, lipid profile and high-sensitivity C-reactive protein (hsCRP) were compared after rhGH therapy for 4-6 months. Results: In GH group, patients were 18-46 (30.0±8.8) years old. The duration after craniopharyngioma surgery was (12.9±5.4) years. Before rhGH therapy, they had got sufficient thyroid and glucocorticoid hormone replacement. After rhGH therapy, the body weight decreased from (92.3±20.1) to (87.6 ±14.6) kg ( P =0.190), with a reduction of BMI from (30.1±5.9) to (28.2±3.7) kg/m(2) ( P =0.120). The waist circumference decreased from (104.4±9.4) cm to (98.8±10.6) cm ( P =0.002). Alanine aminotransferase (ALT) decreased from (52±34) to (28±19) U/L ( P =0.029), with a reduction of aspartate transaminase (AST) from (46±21) to (33±18) U/L ( P =0.035) and γ-glutamyl transpeptadase (GGT) from (59±42) to (29±15) U/L ( P =0.02). hsCRP decreased from (5.3±4.9) to (2.3±2.8) mg/L ( P =0.006) and triglyceride (TG) decreased from (1.8±0.7) to (1.5±0.6) mmol/L ( P =0.028). Fasting blood glucose, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and free fat acid (FFA) were not significantly changed(all P >0.05). In the control group, the above mentioned parameters did not changed significantly during 4-6 months of observational period(all P >0.05). Conclusion: rhGH therapy improves metabolic parameters in patients after craniopharyngioma surgery by decreasing body weight, waist circumstance and fat deposit in liver, as well as

Little is known about the period required for menstruation recovery after long-term luteinizing hormone-releasing hormone (LH-RH) agonist plus tamoxifen therapy following chemotherapy. In this study we investigated the period required for menstruation recovery after the therapy. The subjects comprised 105 premenopausal breast cancer patients who had undergone surgery. All patients were administered an LH-RH agonist for 24 months and tamoxifen for 5 years following the postoperative adjuvant chemotherapy, and the status of menstruation recovery was examined. Menstruation resumed in 16 cases (15.2%) after the last LH-RH agonist treatment session. The mean period from the last LH-RH agonist treatment to the recovery of menstruation was 6.9 months. The rate of menstruation recovery was 35.5% in patients aged 40 years or younger and 8.0% in those aged 41 years or older, and it was significantly higher in those aged 40 years or younger. The period until menstruation recovery tended to be longer in older patients at the end of treatment. This study showed that menstruation resumed after treatment at higher rates in younger patients. However, because it is highly likely that ovarian function will be destroyed by the treatment even in young patients, it is considered necessary to explain the risk to patients and obtain informed consent before introducing this treatment modality.

Menopausal hormone use and ovarian cancer risk

DEFF Research Database (Denmark)

Beral, V; Gaitskell, K; Hermon, C

2015-01-01

BACKGROUND: Half the epidemiological studies with information about menopausal hormone therapy and ovarian cancer risk remain unpublished, and some retrospective studies could have been biased by selective participation or recall. We aimed to assess with minimal bias the effects of hormone therapy...... on ovarian cancer risk. METHODS: Individual participant datasets from 52 epidemiological studies were analysed centrally. The principal analyses involved the prospective studies (with last hormone therapy use extrapolated forwards for up to 4 years). Sensitivity analyses included the retrospective studies....... Adjusted Poisson regressions yielded relative risks (RRs) versus never-use. FINDINGS: During prospective follow-up, 12 110 postmenopausal women, 55% (6601) of whom had used hormone therapy, developed ovarian cancer. Among women last recorded as current users, risk was increased even with

Risk of hormone escape in a human prostate cancer model depends on therapy modalities and can be reduced by tyrosine kinase inhibitors.

Full Text Available Almost all prostate cancers respond to androgen deprivation treatment but many recur. We postulated that risk of hormone escape--frequency and delay--are influenced by hormone therapy modalities. More, hormone therapies induce crucial biological changes involving androgen receptors; some might be targets for escape prevention. We investigated the relationship between the androgen deprivation treatment and the risk of recurrence using nude mice bearing the high grade, hormone-dependent human prostate cancer xenograft PAC120. Tumor-bearing mice were treated by Luteinizing-Hormone Releasing Hormone (LHRH antagonist alone, continuous or intermittent regimen, or combined with androgen receptor (AR antagonists (bicalutamide or flutamide. Tumor growth was monitored. Biological changes were studied as for genomic alterations, AR mutations and protein expression in a large series of recurrent tumors according to hormone therapy modalities. Therapies targeting Her-2 or AKT were tested in combination with castration. All statistical tests were two-sided. Tumor growth was inhibited by continuous administration of the LH-RH antagonist degarelix (castration, but 40% of tumors recurred. Intermittent castration or complete blockade induced by degarelix and antiandrogens combination, inhibited tumor growth but increased the risk of recurrence (RR as compared to continuous castration (RR(intermittent: 14.5, RR(complete blockade: 6.5 and 1.35. All recurrent tumors displayed new quantitative genetic alterations and AR mutations, whatever the treatment modalities. AR amplification was found after complete blockade. Increased expression of Her-2/neu with frequent ERK/AKT activation was detected in all variants. Combination of castration with a Her-2/neu inhibitor decreased recurrence risk (0.17 and combination with an mTOR inhibitor prevented it. Anti-hormone treatments influence risk of recurrence although tumor growth inhibition was initially similar. Recurrent

Fracture incidence in Oslo decreased from the 1970s to the 1990s in younger postmenopausal women, but not in older women or in men. Concurrently, hormone replacement therapy increased considerably. Using data from the Oslo Health Study, we estimated that roughly half the decline might be attributed hormone replacement therapy. Between the late 1970s and the late 1990s, the incidence of hip fracture and distal forearm fracture decreased in younger postmenopausal women in Oslo, but not in elderly women or in men. The purpose of this report is to evaluate whether the decreased incidence was coherent with trends in use of hormone replacement therapy (HRT). Data on estrogens were collected from official drug statistics, data on fractures from published studies and data on bone mineral density (BMD) from the Oslo Health Study. The sale of all estrogens increased 22 times from 1979 to 1999, and the sub-category estradiol combined with progestin increased 35 times. In the corresponding period the incidence of distal forearm fracture in women aged 50-64 years decreased by 33% and hip fracture by 39%. Based on differences in BMD between users and non-users of HRT, we estimated that up to half of this decline might be due to HRT. The reduction in fracture incidence in postmenopausal women in Oslo occurred in a period with a substantial increase in the use of HRT. Future surveillance will reveal whether the last years' decline in use of HRT will be translated into increasing fracture rates.

Objectives: The extent and relevance of altered bone metabolism for statural growth in children with chronic kidney disease is controversial. We analyzed the impact of renal dysfunction and recombinant growth hormone therapy on a panel of serum markers of bone metabolism in a large pediatric...... turnover state in children with chronic kidney disease. Growth hormone induces an osteoanabolic pattern and normalizes osteocyte activity. The osteocyte markers cFGF23 and sclerostin are associated with standardized height, and the markers of bone turnover predict height velocity......./min/ 1.73m2. 41 children receiving recombinant growth hormone therapy were compared to an untreated matched control group. Results: Standardized levels of BAP, TRAP5b and cFGF-23 were increased whereas sclerostin was reduced. BAP was correlated positively and cFGF-23 inversely with eGFR. Intact serum...

Studies on blood levels of hormones in patients undergoing surgery and radiation therapy for cervical cancer, 3

International Nuclear Information System (INIS)

Tanaka, Motofumi

1984-01-01

Blood levels of LH, FSH, prolactin (PRL), progesterone (Prog), estrone (E 1 ), estradiol (E 2 ), testosterone (T), and cortisol (Cor) were determined in 5 patients treated with radiation therapy following surgical transposition of the ovaries (group A) and in 9 patients treated with surgical transposition alone (group B). Although disturbance in ovarian function was transiently observed during and after X-ray irradiation in the group A, blood levels of hormones returned to normal at 5-7 months after the completion of treatment. Cyclic changes in blood hormones were observed in 4 patients. These results indicated that ovarian function is fully conserved after X-ray irradiation. No remarkable changes in blood hormones were observed in the group B, suggesting that there is no effect of surgical procedure on ovarian function. However, because one patient receiving anticancer agents had transient disturbance in ovarian function, caution is necessary in the selection of anticancer agents. Surgical transposition of the ovaries is therefore considered to be a very simple, reasonable procedure when radiation therapy is required in patients with Ib or more advanced stages cervical cancer.

Thirty-three acromegalic patients were treated with radiotherapy and followed up for at least 3 years (mean 6 years, range 3 to 12). Seventeen had not had previous pituitary ablative therapy and 16 had. The mean GH level for these two groups before radiotherapy was comparable at 98 and 119 mlU/l. The observed frequency of reaching <10 mlU/L was 53% and 75% of patients in the two groups, respectively, the mean observed falls in growth hormone level were 81 and 85% of the initial level, and the calculated exponential decline rate of GH level was 72 and 52% per fyear. Considering all 35 patients, requirement for pituitary hormone replacement therapy increased from 15 patients before radiotherapy to 20 after radiotherapy, being mostly those who had had prior ablative therapies. There were no complications attributable to the radiotherapy treatment. It appears that radiotherapy is equally efficacious whether a prior unsuccessful ablative procedure had been used or not.

The combined treatment (ADT–EBRT also seems to play a significant role in improving treatment results in the intermediate-risk group of prostate cancer patients. On the other hand, there is a growing body of evidence that treatment with ADT can be associated with serious and lifelong adverse events including osteoporosis, cardiovascular disease, diabetes, and many others. Almost all ADT adverse events are time dependant and tend to increase in severity with prolongation of hormonal manipulation. Therefore, it is crucial to clearly state the optimal schedule for ADT in combination with EBRT, that maintaining the positive effect on treatment efficacy would keep the adverse events risk at reasonable level. To achieve this goal, treatment schedule may have to be highly individualized on the basis of the patient-specific potential vulnerability to adverse events. In this study, the concise and evidence-based review of current literature concerning the general rationales for combining radiotherapy and hormonal therapy, its mechanism, treatment results, and toxicity profile is presented.Keywords: prostate cancer, radiotherapy, androgen deprivation, combined treatment

Purpose ASCO provisional clinical opinions (PCOs) offer direction to the ASCO membership after publication or presentation of potential practice-changing data. This PCO addresses second-line hormonal therapy for chemotherapy-naïve men with castration-resistant prostate cancer (CRPC) who range from being asymptomatic with only biochemical evidence of CRPC to having documented metastases but minimal symptoms. Clinical Context The treatment goal for CRPC is palliation. Despite resistance to initial androgen deprivation therapy, most men respond to second-line hormonal therapies. However, guidelines have neither addressed second-line hormonal therapy for nonmetastatic CRPC nor provided specific guidance with regard to the chemotherapy-naïve population. Recent Data Six phase III randomized controlled trials and expert consensus opinion inform this PCO. Provisional Clinical Opinion For men with CRPC, a castrate state should be maintained indefinitely. Second-line hormonal therapy (eg, antiandrogens, CYP17 inhibitors) may be considered in patients with nonmetastatic CRPC at high risk for metastatic disease (rapid prostate-specific antigen doubling time or velocity) but otherwise is not suggested. In patients with radiographic evidence of metastases and minimal symptoms, enzalutamide or abiraterone plus prednisone should be offered after discussion with patients about potential harms, benefits, costs, and patient preferences. Radium-223 and sipuleucel-T also are options. No evidence provides guidance about the optimal order of hormonal therapies for CRPC beyond second-line treatment. Prostate-specific antigen testing every 4 to 6 months is reasonable for men without metastases. Routine radiographic restaging generally is not suggested but can be considered for patients at risk for metastases or who exhibit symptoms or other evidence of progression.

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

Hormone Therapy and Cardiovascular Disease

Full Text Available As in other Western countries, cardiovascular disease (CVD is the leading cause of death among women in Taiwan, exceeding the mortality from cervical or breast cancer. Women generally present with CVD after menopause and later than men, since menopause-related estrogen deficiency has been considered to be associated with an increased risk for CVD. Thus, coronary artery diseases and stroke are the two main contributors of mortality among postmenopausal women. Observational studies have reported a reduction in coronary artery disease risk after hormone therapy (HT ranging from 31-44%. However, recent randomized controlled trials that evaluated the effect of HT on primary and secondary CVD prevention have questioned the efficacy of HT, despite confirming the lipid-lowering effect of estrogen. However, a cluster of factors are responsible for the genesis and progression of CVD. Until we further evaluate their specific actions and how these different factors interact, the issue related to HT and cardiovascular risk will remain unsettled. Since these studies have contributed to our understanding of the benefits and risks associated with HT, HT use should be individualized after consideration of the condition of each postmenopausal patient. Ideally, the efficacy of different preparations and dosages of HT in postmenopausal women who are at risk of CVD, before atheromatous lesions have developed, should be investigated.

Levothyroxine (l-T4) is commonly employed to correct hormone deficiency in children with congenital hypothyroidism (CH) and in adult patients with iatrogenic hypothyroidism. To compare the daily weight-based dosage of the replacement therapy with l-T4 in athyreotic adult patients affected by CH and adult patients with thyroid nodular or cancer diseases treated by total thyroidectomy. A total of 36 adult patients (27 females and nine males) aged 18-29 years were studied; 13 patients (age: 21.5±2.1, group CH) had athyreotic CH treated with l-T4 since the first days of life. The remaining 23 patients (age: 24±2.7, group AH) had hypothyroidism after total thyroidectomy (14 patients previously affected by nodular disease and nine by thyroid carcinoma with clinical and biochemical remission). Patient weight, serum free thyroid hormones, TSH, thyroglobulin (Tg), anti-Tg, and anti-thyroperoxidase antibodies were measured. Required l-T4 dosage was evaluated. At the time of the observations, all patients presented free thyroid hormones within the normal range and TSH between 0.8 and 2 μIU/ml. Patients had undetectable Tg and anti-thyroid antibodies. The daily weight-based dosage of the replacement therapy with l-T4 to reach euthyroidism in patients of group CH was significantly higher than that in those of group AH (2.16±0.36 vs 1.73±0.24 μg/kg, Phypothyroidism, patients of group CH required a daily l-T4 dose/kg higher than group AH patients, despite higher levels of TSH. The different requirement of replacement therapy between adult patients with congenital and those with surgical athyroidism could be explained by a lack of thyroid hormones since fetal life in CH, which could determine a different set point of the hypothalamus-pituitary-thyroid axis. © 2014 European Society of Endocrinology.

[Puberty-delaying hormone therapy in adolescents with gender identity disorder].

2013-01-01

The guideline for the treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology was revised in January 2012. The guideline eased restrictions for the endocrine treatment of transsexual adolescents. A medical specialist can start treating transsexual adolescents at the age of 15 after the diagnosis of GID. It recommends that transsexual adolescents (Tanner stage 2 [mainly 12-13 years of age]) are treated by endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until the age of 15 years old, after which cross-sex hormones may be given. Female-to-male transsexuals do not necessarily want to start androgen therapy before presenting female secondary sexual characteristics because androgen can easily stop menstruation, cause beard growth, and lower the voice. On the contrary, male-to-female transsexuals want to start estrogen therapy before presenting male secondary sexual characteristics because estrogen cannot alter the beard and low voice. It is important to identify children with gender dysphoria in school and help them receive medical advice. However, approximately half of school teachers think that children with gender dysphoria are very rare and they do not know of the notification from Ministry of Education, Culture, Sports, Science and Technology, JAPAN, which aims to help children with gender dysphoria. The revision of the guideline for the treatment of transsexual people and endocrine treatment of transsexual adolescents by medical specialists may prevent them from attempting suicide, being depressive, and refusing to attend school. Furthermore, the treatment may help avoid mental disorders, aid being employed with the desired sexuality, and, subsequently, getting married and having children.

Litsas, G

2013-09-01

Growth hormone (GH) has significant effects on linear bone growth, bone mass and bone metabolism. The primary role of GH supplementation in children with GH deficiency, those born small for gestational age or with other types of disorders in somatic development is to increase linear growth. However, GH therapy seems to elicit varying responses in the craniofacial region. Whereas the effects of GH administration on somatic development are well documented, comparatively little is known of its effects on the craniofacial region. The purpose of this review was to search the literature and compile results from both animal and human studies related to the impact of GH on craniofacial growth. © 2012 John Wiley & Sons A/S.

Salivary cortisol and explicit memory in postmenopausal women using hormone replacement therapy.

Science.gov (United States)

Hampson, Elizabeth; Duff-Canning, Sarah J

2016-02-01

Circulating cortisol levels are known to influence explicit memory in humans and other primates. The present study investigated salivary cortisol and its association with explicit memory performance in 99 postmenopausal women (64 treated with conjugated equine estrogens or estradiol, and 35 matched controls not using any form of hormone therapy). Controls were compared with treated women taking estrogens alone (n=39), or taking estrogens in combination with a progestin (n=25). Mean time on hormone therapy was approximately 5 years, with initiation of treatment in close proximity to the onset of menopause. Explicit memory was assessed with the California Verbal Learning Test (CVLT). Saliva was collected before (basal or resting sample) and after (post-test sample) completing a set of cognitive tasks. Cortisol was measured using a high-sensitivity radioimmunoassay. Treated women were found to have higher resting cortisol concentrations than controls matched for time of day. Basal cortisol was a modest predictor of learning and memory on the CVLT. Higher cortisol was associated with better recall and fewer memory errors, which is consistent with experimental studies examining explicit memory under small increases in circulating cortisol load. Potential cumulative effects on the central nervous system of sustained exposure to mildly increased cortisol in conjunction with the long-term use of oral estrogens are discussed in the context of aging and dementia.

Shared decision making and patient choice for growth hormone therapy: current perspectives

Directory of Open Access Journals (Sweden)

2016-06-01

Full Text Available Belinda George, Vageesh Ayyar Department of Endocrinology, St. John’s Medical College Hospital, Bangalore, Karnataka, India Abstract: Growth hormone has now been available in medical practice for close to 50 years. Its use has provided dramatic results in patients with growth hormone deficiency and it is associated with an overall favorable safety profile. Over the years, the utility of growth hormone has expanded to include treatment for short stature associated with conditions other than growth hormone deficiency, and this situation warrants greater involvement of the child and parents in the shared decision-making process. Shared decision making is in good conformance to the principle of informed consent, and it also improves the compliance and adherence to therapy as the patient fully understands the benefit and safety of the treatment. In the pediatric-care setting, the decision-making interactions usually occur between the health care provider, patient, and parents. The process may range from an autonomous decision-making pattern, where the patient or parents are fully responsible for the decision taken, to the paternalistic decision-making pattern, where the health care provider assumes full responsibility for the decision taken. However, the ideal situation is one where a truly shared decision-making process happens, in which the doctor and patient/parents work together to choose an evidence-based option, in line with the patient’s preferences and wishes. The limited data available on shared decision making with regard to growth hormone replacement, however, is not very encouraging and suggests that the actual involvement of the parents as perceived by them is less than optimal. Introduction of a simple structured model for a shared decision-making process that can be easily incorporated into clinical practice and familiarization of health care providers with the same is essential to improve our shared decision-making practices

To determine whether menopausal hormone therapy (HT) affects regional brain volumes, including hippocampal and frontal regions. Brain MRI scans were obtained in a subset of 1,403 women aged 71-89 years who participated in the Women's Health Initiative Memory Study (WHIMS). WHIMS was an ancillary study to the Women's Health Initiative, which consisted of two randomized, placebo-controlled trials: 0.625 mg conjugated equine estrogens (CEE) with or without 2.5 mg medroxyprogesterone acetate (MPA) in one daily tablet. Scans were performed, on average, 3.0 years post-trial for the CEE + MPA trial and 1.4 years post-trial for the CEE-Alone trial; average on-trial follow-up intervals were 4.0 years for CEE + MPA and 5.6 years for CEE-Alone. Total brain, ventricular, hippocampal, and frontal lobe volumes, adjusted for age, clinic site, estimated intracranial volume, and dementia risk factors, were the main outcome variables. Compared with placebo, covariate-adjusted mean frontal lobe volume was 2.37 cm(3) lower among women assigned to HT (p = 0.004), mean hippocampal volume was slightly (0.10 cm(3)) lower (p = 0.05), and differences in total brain volume approached significance (p = 0.07). Results were similar for CEE + MPA and CEE-Alone. HT-associated reductions in hippocampal volumes were greatest in women with the lowest baseline Modified Mini-Mental State Examination scores (scores equine estrogens with or without MPA are associated with greater brain atrophy among women aged 65 years and older; however, the adverse effects are most evident in women experiencing cognitive deficits before initiating hormone therapy.

In a 58-year-old postmenopausal woman blood flow and blood pool images of bone scintigraphy showed a focus of increased activity in the right pelvic region. Computed tomography and ultrasound exhibited no abnormalities in the abdomen; especially the uterus and ovaries were normal. Careful anamnestic evaluation revealed that the patient received a long-term peroral estrogen/gestagen replacement therapy for the prevention of osteoporosis, but did not have menstruation-like bleedings for the last twelve months of therapy. At time of admission, the patient was on day 25 of hormone replacement therapy, and the uterus wash, therefore, in a premenstrual stage. Hence, despite cessation of bleedings in postmenopausal women, one should think of hormone replacement therapy as an explanation for vascular pelvic tumors seen by the first two phases of bone scintigraphy, before further diagnostic steps are undertaken.

Full Text Available Abstract Background Oestrogen and progestogen have the potential to influence gastro-intestinal motility; both are key components of hormone replacement therapy (HRT. Results of observational studies in women taking HRT rely on self-reporting of gastro-oesophageal symptoms and the aetiology of gastro-oesophageal reflux disease (GORD remains unclear. This study investigated the association between HRT and GORD in menopausal women using validated general practice records. Methods 51,182 menopausal women were identified using the UK General Practice Research Database between 1995–2004. Of these, 8,831 were matched with and without hormone use. Odds ratios (ORs were calculated for GORD and proton-pump inhibitor (PPI use in hormone and non-hormone users, adjusting for age, co-morbidities, and co-pharmacy. Results In unadjusted analysis, all forms of hormone use (oestrogen-only, tibolone, combined HRT and progestogen were statistically significantly associated with GORD. In adjusted models, this association remained statistically significant for oestrogen-only treatment (OR 1.49; 1.18–1.89. Unadjusted analysis showed a statistically significant association between PPI use and oestrogen-only and combined HRT treatment. When adjusted for covariates, oestrogen-only treatment was significant (OR 1.34; 95% CI 1.03–1.74. Findings from the adjusted model demonstrated the greater use of PPI by progestogen users (OR 1.50; 1.01–2.22. Conclusions This first large cohort study of the association between GORD and HRT found a statistically significant association between oestrogen-only hormone and GORD and PPI use. This should be further investigated using prospective follow-up to validate the strength of association and describe its clinical significance.

Purpose: To report the preliminary results of a Phase I/II study combining radiotherapy and in situ gene therapy (adenovirus/herpes simplex virus thymidine kinase gene/valacyclovir) with or without hormonal therapy in the treatment of prostate cancer. Methods and Materials: Arm A: low-risk patients (T1-T2a, Gleason score <7, pretreatment PSA <10) were treated with combined radio-gene therapy. A mean dose of 76 Gy was delivered to the prostate with intensity-modulated radiotherapy. Arm B: high-risk patients (T2b-T3, Gleason score ≥7, pretreatment PSA ≥10) were treated with combined radio-gene therapy and hormonal therapy. Hormonal therapy was comprised of a 4-month leuprolide injection and 2-week use of flutamide. Arm C: Stage D1 (positive pelvic lymph node) patients received the same regimen as Arm B, with the additional 45 Gy to the pelvic lymphatics. Treatment-related toxicity was assessed using Cancer Therapy Evaluation Program common toxicity score and Radiation Therapy Oncology Group (RTOG) toxicity score. Results: Thirty patients (13 in Arm A, 14 in Arm B, and 3 in Arm C) completed the trial. Median follow-up was 5.5 months. Eleven patients (37%) developed flu-like symptoms (Cancer Therapy Evaluation Program Grade 1) of fatigue and chills/rigors after gene therapy injection but recovered within 24 h. Four patients (13%) and 2 patients (7%) developed Grade 1 and 2 fever, respectively. There was no patient with weight loss. One patient in Arm B developed Grade 3 elevation in liver enzyme, whereas 11 and 2 patients developed Grade 1 and 2 abnormal liver function tests. There was no Grade 2 or above hematologic toxicity. Three patients had transient rise in creatinine. There was no RTOG Grade 3 or above lower gastrointestinal toxicity. Toxicity levels were as follows: 4 patients (13%), Grade 2; 6 patients (20%), Grade 1; and 20 patients (67%), no toxicity. There was 1 patient with RTOG Grade 3 genitourinary toxicity, 12 patients (40%) with Grade 2, 8 patients

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

To evaluate the impact of neoadjuvant hormonal therapy (NHT) on quality of life after external-beam radiotherapy (EBRT) for prostate cancer. A group of 170 patients (85 with and 85 without NHT) has been surveyed prospectively before EBRT (70.2-72 Gy), at the last day of EBRT, a median time of 2 months and 15 months after EBRT using a validated questionnaire (Expanded Prostate Cancer Index Composite). Pairs with and without NHT (median treatment time of 3.5 months before EBRT) were matched according to the respective planning target volume and prostate volume. Before EBRT, significantly lower urinary function/bother, sexual function and hormonal function/bother scores were found for patients with NHT. More than 1 year after EBRT, only sexual function scores remained lower. In a multivariate analysis, NHT and adjuvant hormonal therapy (HT) versus NHT only (hazard ratio 14; 95% confidence interval 2.7-183; p = 0.02) and luteinizing hormone-releasing hormone (LHRH) agonists versus antiandrogens (hazard ratio 3.6; 95% confidence interval 1.1-12; p = 0.04) proved to be independent risk factors for long-term erectile dysfunction (no or very poor ability to have an erection). With the exception of sexual function (additional adjuvant HT and application of LHRH analog independently adverse), short-term NHT was not found to decrease quality of life after EBRT for prostate cancer.

Sex Hormones and the QT Interval: A Review

Science.gov (United States)

Sedlak, Tara; Shufelt, Chrisandra; Iribarren, Carlos

2012-01-01

Abstract A prolonged QT interval is a marker for an increased risk of ventricular tachyarrhythmias. Both endogenous and exogenous sex hormones have been shown to affect the QT interval. Endogenous testosterone and progesterone shorten the action potential, and estrogen lengthens the QT interval. During a single menstrual cycle, progesterone levels, but not estrogen levels, have the dominant effect on ventricular repolarization in women. Studies of menopausal hormone therapy (MHT) in the form of estrogen-alone therapy (ET) and estrogen plus progesterone therapy (EPT) have suggested a counterbalancing effect of exogenous estrogen and progesterone on the QT. Specifically, ET lengthens the QT, whereas EPT has no effect. To date, there are no studies on oral contraception (OC) and the QT interval, and future research is needed. This review outlines the current literature on sex hormones and QT interval, including the endogenous effects of estrogen, progesterone, and testosterone and the exogenous effects of estrogen and progesterone therapy in the forms of MHT and hormone contraception. Further, we review the potential mechanisms and pathophysiology of sex hormones on the QT interval. PMID:22663191

Menopause may be a risk factor for hearing loss, and postmenopausal hormone therapy (HT) has been proposed to slow hearing decline; however, there are no large prospective studies. We prospectively examined the independent relations between menopause and postmenopausal HT and risk of self-reported hearing loss. Prospective cohort study among 80,972 women in the Nurses' Health Study II, baseline age 27 to 44 years, followed from 1991 to 2013. Baseline and updated information was obtained from detailed validated biennial questionnaires. Cox proportional-hazards regression models were used to examine independent associations between menopausal status and postmenopausal HT and risk of hearing loss. After 1,410,928 person-years of follow-up, 18,558 cases of hearing loss were reported. There was no significant overall association between menopausal status, natural or surgical, and risk of hearing loss. Older age at natural menopause was associated with higher risk. The multivariable-adjusted relative risk of hearing loss among women who underwent natural menopause at age 50+ years compared with those aged less than 50 years was 1.10 (95% confidence interval [CI] 1.03, 1.17). Among postmenopausal women, oral HT (estrogen therapy or estrogen plus progestogen therapy) was associated with higher risk of hearing loss, and longer duration of use was associated with higher risk (P trend menopause and longer duration of postmenopausal HT are associated with higher risk of hearing loss.

The Women's Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS. We contacted 2,345 women at 14 WHIMS sites; scans were completed on 1,424 (61%) and 1,403 were accepted for analysis. The primary outcome measure was total ischemic lesion volume on brain MRI. Mean duration of on-trial HT or placebo was 4 (CEE+MPA) or 5.6 years (CEE-Alone) and scans were conducted an average of 3 (CEE+MPA) or 1.4 years (CEE-Alone) post-trial termination. Cross-sectional analysis of MRI lesions was conducted; general linear models were fitted to assess treatment group differences using analysis of covariance. A (two-tailed) critical value of alpha = 0.05 was used. In women evenly matched within trials at baseline, increased lesion volumes were significantly related to age, smoking, history of cardiovascular disease, hypertension, lower post-trial global cognition scores, and increased incident cases of on- or post-trial mild cognitive impairment or probable dementia. Mean ischemic lesion volumes were slightly larger for the CEE+MPA group vs placebo, except for the basal ganglia, but the differences were not significant. Women assigned to CEE-Alone had similar mean ischemic lesion volumes compared to placebo. Conjugated equine estrogen-based hormone therapy was not associated with a significant increase in ischemic brain lesion volume relative to placebo. This finding was consistent within each trial and in pooled analyses across trials.

Full Text Available There has been an increasing use of hormonal therapy among male-to-female (MtF transgender individuals. This long-term hormone replacement therapy (HRT renders MtF individuals a unique patient subgroup in terms of breast cancer risk. This case describes a MtF transgender who presented with a breast lesion concerning for malignancy following hormonal replacement therapy. The patient additionally had a strong family history of breast cancer. Final pathology revealed lobular hyperplasia in the setting of gynecomastia and pseudoangiomatous stromal hyperplasia (PASH. Both pathology findings are rare in biological females, let alone in the setting of hormone replacement therapy in a MtF individual. While the number of reported cases of suspicious breast lesions in this population remains scarce, it presents both a diagnostic and therapeutic challenge due to the nature of the treatment course and the lack of research in this recently growing subgroup of patients.

The history of pituitary growth hormone (GH) started 100 years ago but the isolation purification and determination of the chemical structure of the human GH (hGH) took another 50 years. Starting in 1957 hGH was extracted from cadaver pituitaries and its clinical use was restricted to severe GH deficient patient. With the invention of recombinant biosynthetic hGH in 1985; the indications for its use were extended. The major approved medications are GH deficiency and short statured children of various etiologies. This is a critical review of present and future use of human GH. To evaluate the effectiveness of the hGH treatment several pharmaceutical companies established postmarketing follow-up programs which are based on the reliability and cooperation of the treating physicians. Unfortunately they stop when the treatment is terminated and most studies refer to growth stimulation effectiveness during initial years but do not follow the children until final height. The long-term experience enabled to evaluate adverse effects (AE), the majority being due to large dosage. The most serious AE reported are increases in malignancies and early or late mortality in adult age. There is consensus that GH deficient children need replacement therapy. As long-term hGH treatment is expensive and the final height gains in non-GH deficient children small the cost-benefit indications to treat short children without a disease has been questioned. To avoid the need of daily injections, long-acting hGH preparations undergo clinical trials. The future will show their effectiveness and eventual adverse effects.

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.

Thyroid Hormones and Antioxidant Systems: Focus on Oxidative Stress in Cardiovascular and Pulmonary Diseases

Full Text Available In previous works we demonstrated an inverse correlation between plasma Coenzyme Q10 (CoQ10 and thyroid hormones; in fact, CoQ10 levels in hyperthyroid patients were found among the lowest detected in human diseases. On the contrary, CoQ10 is elevated in hypothyroid subjects, also in subclinical conditions, suggesting the usefulness of this index in assessing metabolic status in thyroid disorders. A Low-T3 syndrome is a condition observed in several chronic diseases: it is considered an adaptation mechanism, where there is a reduction in pro-hormone T4 conversion. Low T3-Syndrome is not usually considered to be corrected with replacement therapy. We review the role of thyroid hormones in regulation of antioxidant systems, also presenting data on total antioxidant capacity and Coenzyme Q10. Published studies suggest that oxidative stress could be involved in the clinical course of different heart diseases; our data could support the rationale of replacement therapy in low-T3 conditions.

Most studies that have examined the effects of mammographic density and hormone therapy use on breast cancer detection have included screen-film mammography. This study further examines this association in post-menopausal women screened by digital mammography. Approved by the University of Toronto Research Ethics Board, this study identified 688,418 women of age 50-74 years screened with digital or screen-film mammography from 2008 to 2009 within the Ontario Breast Screening Program. Of 2993 eligible women with invasive breast cancer, 2450 were contacted and 1421 participated (847 screen-film mammography, 574 digital direct radiography). Mammographic density was measured by study radiologists using the standard BI-RADS classification system and by a computer-assisted method. Information on hormone therapy use was collected by a telephone-administered questionnaire. Logistic regression and two-tailed tests for significance evaluated associations between factors and detection method by mammography type. Women with >75 % radiologist-measured mammographic density compared to those with diagnosed with an interval than screen-detected cancer, with the difference being greater for those screened with screen-film (OR = 6.40, 95 % CI 2.30-17.85) than digital mammography (OR = 2.41, 95 % CI 0.67-8.58) and aged 50-64 years screened with screen-film mammography (OR = 10.86, 95 % CI 2.96-39.57). Recent former hormone therapy users were also at an increased risk of having an interval cancer with the association being significant for women screened with digital mammography (OR = 2.08, 95 % CI 1.17-3.71). Breast screening using digital mammography lowers the risk of having an interval cancer for post-menopausal women aged 50-64 with greater mammographic density.

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.

Purpose: To estimate the effect of fasting during Ramadan (the ninth lunar month) on adherence to oral hormonal therapies (OHT) among breast cancer (BC) patients. Patients and Methods: During Ramadan 2010, 139 BC patients were interviewed at the Egyptian National Cancer Institute. They were asked about fasting as well as intake of OHT in Ramadan and in the preceding month. Results: The median age was 50 years and most patients were postmenopausal with good performance status and non-metastatic disease. The median number of fasting days was 18% and 93% of patients were fasting 80% or more of Ramadan. Tamoxifen and aromatase inhibitors were used in 64% and 36%, respectively. Adherence to OHT during Ramadan and its preceding month were 94.2% and 95.7%, respectively (p = 0.77). In univariate analysis, non-adherence prior to Ramadan and shorter duration of OHT were predictors of non-adherence during Ramadan (P < 0.001, 0.003, respectively). Fasting, age, performance status, presence of metastases and type of hormonal therapy were not good predictors of adherence. Conclusions: While most of patients receiving OHT for BC are fasting during Ramadan, this does not negatively impact compliance with treatment

Objective: To explore the association between postmenopausal hormone therapy (HT) and Alzheimer disease (AD). Methods: Twenty-year follow-up data from the Kuopio Osteoporosis Risk Factor and Prevention study cohort were used. Self-administered questionnaires were sent to all women aged 47–56 years, residing in Kuopio Province starting in 1989 until 2009, every 5th year. Register-based information on HT prescriptions was available since 1995. Probable AD cases, based on DSM-IV and National Institute of Neurological and Communicative Disorders and Stroke–Alzheimer's Disease and Related Disorders Association criteria, were identified from the special reimbursement register (1999–2009). The study population included 8,195 women (227 cases of incident AD). Results: Postmenopausal estrogen use was not associated with AD risk in register-based or self-reported data (hazard ratio/95% confidence interval 0.92/0.68–1.2, 0.99/0.75–1.3, respectively). Long-term self-reported postmenopausal HT was associated with reduced AD risk (0.53/0.31–0.91). Similar results were obtained with any dementia diagnosis in the hospital discharge register as an outcome. Conclusions: Our results do not provide strong evidence for a protective association between postmenopausal HT use and AD or dementia, although we observed a reduced AD risk among those with long-term self-reported HT use.

The state of bone health and the effect of growth hormone (GH) therapy on bone and body composition in children with idiopathic short stature (ISS) are largely unknown. A direct role of GH deficiency (GHD) on bone density is controversial. Using dual-energy X-ray absorptiometry, this study measured total body bone mineral content (TB BMC), body composition, and volumetric bone mineral density (vBMD) at the lumbar spine (LS) and femoral neck (FN) in 77 children (aged 3-17 years) with ISS (n = 57) and GHD (n = 20). Fifty-five children (GHD = 13) receiving GH were followed over 24 months including measurement of bone turnover. At diagnosis, size-corrected TB BMC SDS was greater (P bone relation, as assessed by the BMC/lean mass (LTM) ratio SDS was not different between groups. During GH therapy, prepubertal GHD children gained more height (1.58 [0.9] SDS) and LTM (0.87 [0.63] SDS) compared to prepubertal ISS children (0.75 [0.27] and 0.17 [0.25] SDS, respectively). Percent body fat decreased in GHD (-5.94% [4.29]) but not in ISS children. Total body BMC accrual was less than predicted in all groups accompanied by an increase in bone turnover. Puberty led to the greatest absolute, but not relative, increments in weight, LTM, BMI, bone mass, and LSvBMD. Our results show that children with ISS and GHD differ in their response to GH therapy in anthropometry, body composition, and bone measures. Despite low vBMD values at diagnosis in both prepubertal groups, size-corrected regional or TB bone data were generally within the normal range and did not increase during GH therapy in GHD or ISS children. Growth hormone had great effects on the growth plate and body composition with subsequent gains in height, LTM, bone turnover, and bone mass accrual, but no benefit for volumetric bone density over 2 years.

Methimazole-Induced Goitrogenesis in an Adult Patient With the Syndrome of Resistance to Thyroid Hormone

Full Text Available Patients with the syndrome of resistance to thyroid hormone (RTH have clinical (tachycardia and anxiety and biochemical (elevated thyroid hormones level features of hyperthyroidism. Based on previous reports in pediatric patients with the RTH, antithyroid treatment in these patients is not indicated. Clinical and biochemical sequel of antithyroid therapy in an adult patient with RTH was not previously reported. A 63-year-old African American female with history of RTH was treated with a therapy consisting of methimazole 15 mg daily and atenolol. Methimazole treatment resulted in reduction in thyroid hormone level while the patient’s TSH increased with a peak of 24.88 mIU/L. Having achieved biochemical euthyroidism, the patient developed thyroid gland enlargement associated with progressive symptoms of dysphagia and dyspnea. Examination demonstrated globally enlarged firm thyroid gland with areas of nodularity in both lobes. A computed tomography of the neck showed enlarged thyroid gland with extension around bilateral sternocleidomastoid muscles and compression onto the trachea. Methimazole therapy was discontinued and patient was treated just on atenolol. Over 12 months following discontinuation of methimazole, the patient experienced marked clinical and radiographic improvement of the goiter size associated with TSH reduction to 1.26 mIU/L and modest free thyroxine increase as expected in RTH. It seems appealing to treat patients with the RTH with antithyroid medications. However, in these patients decrease in thyroid hormone levels will stimulate TSH production, which can, in turn, predispose to goiter formation. Our report supports prior observations in children with RTH that treatment with methimazole is not indicated in adult patients with RTH.

The mechanisms linking ovarian hormones to negative affect are poorly characterized, but important clues may come from the examination of the brain's intrinsic organization. Here, we studied the effects of both the menstrual cycle and oral contraceptives (OCs) on amygdala and salience network resting-state functional connectivity using a double-blind, randomized, and placebo-controlled design. Hormone levels, depressive symptoms, and resting-state functional connectivity were measured in 35 healthy women (24.9±4.2 years) who had previously experienced OC-related negative affect. All participants were examined in the follicular phase of a baseline cycle and in the third week of the subsequent cycle during treatment with either a combined OC (30 μg ethinyl estradiol/0.15 mg levonorgestrel) or placebo. The latter time point targeted the midluteal phase in placebo users and steady-state ethinyl estradiol and levonorgestrel concentrations in OC users. Amygdala and salience network connectivity generally increased with both higher endogenous and synthetic hormone levels, although amygdala-parietal cortical connectivity decreased in OC users. When in the luteal phase, the naturally cycling placebo users demonstrated higher connectivity in both networks compared with the women receiving OCs. Our results support a causal link between the exogenous administration of synthetic hormones and amygdala and salience network connectivity. Furthermore, they suggest a similar, potentially stronger, association between the natural hormonal variations across the menstrual cycle and intrinsic network connectivity.

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.

Although systemic therapy is one of the cornerstones of therapy for premenopausal women with early stage breast cancer, there remain many unknowns regarding its optimal use. By accident of clinical trial design, much clinical investigation in premenopausal women has focused on chemotherapy. More recently the value of endocrine therapy (tamoxifen and ovarian suppression/ablation via surgery, LHRH agonists, or chemotherapy-induced menopause) has become apparent, and some form of endocrine therapy is viewed as standard for virtually all premenopausal women with early stage invasive breast cancer that expresses estrogen and/or progesterone receptor. Critical open questions include type and duration of endocrine therapy and the development of prognostic/predictive markers to help identify patients who are likely to benefit from chemotherapy in addition to endocrine therapy. For some years, five years of tamoxifen has been viewed as the standard endocrine therapy for premenopausal hormone-responsive breast cancer, although the ATLAS trial suggests that an additional five years of tamoxifen can be considered. The MA17 trial also suggests that an additional five years of an aromatase inhibitor can be considered for women who become postmenopausal during tamoxifen therapy. Information about the value of ovarian suppression continues to emerge, most recently with the demonstration of excellent outcome with goserelin plus tamoxifen in the ABCSG12 trial. The SOFT and TEXT trials, whose accrual is now complete, should help to define optimal endocrine therapy. In addition, use of the 21-gene recurrence score assay may help to delineate the additional value of chemotherapy for patients with node-negative breast cancer, and its utility in the setting of women with 1-3 positive lymph nodes is under study in the RxPONDER trial. Nonetheless, the need for other predictive biomarkers to select appropriate therapy remains real. Finally, attention to long term benefits and side effects

Experimental and clinical data support the inhibitory effect of testosterone on breast tissue and breast cancer. However, testosterone is aromatized to estradiol, which exerts the opposite effect. The aim of this study was to determine the effect of testosterone, combined with the aromatase inhibitor anastrozole, on a hormone receptor positive, infiltrating ductal carcinoma in the neoadjuvant setting. To determine clinical response, we obtained serial ultrasonic measurements and mammograms before and after therapy. Three combination implants-each containing 60 mg of testosterone and 4 mg of anastrozole-were placed anterior, superior, and inferior to a 2.4-cm tumor in the left breast. Three additional testosterone-anastrozole implants were again placed peritumorally 48 days later. By day 46, there was a sevenfold reduction in tumor volume, as measured on ultrasound. By week 13, we documented a 12-fold reduction in tumor volume, demonstrating a rapid logarithmic response to intramammary testosterone-anastrozole implant therapy, equating to a daily response rate of 2.78% and a tumor half-life of 23 days. Therapeutic systemic levels of testosterone were achieved without elevation of estradiol, further demonstrating the efficacy of anastrozole combined with testosterone. This novel therapy, delivered in the neoadjuvant setting, has the potential to identify early responders and to evaluate the effectiveness of therapy in vivo. This may prove to be a new approach to both local and systemic therapies for breast cancer in subgroups of patients. In addition, it can be used to reduce tumor volume, allowing for less surgical intervention and better cosmetic oncoplastic results.

This article aims to explain the reasons for the remarkable change in age of breast cancer occurrence in the Swiss canton of Geneva. We used population-based data from the Geneva cancer registry, which collects information on method of detection, stage and tumour characteristics since 1975. For patients diagnosed between 1997–2003, we obtained additional information on use of hormone replacement therapy from a large prospective study on breast cancer. Using generalized log linear regression analysis, we compared age-specific incidence rates with respect to period, stage, oestrogen receptor status, method of detection and use of hormone replacement therapy. In the periods 1975–1979 and 1985–1989, breast cancer risk increased with age, showing the highest incidence rates among women aged ≥ 85 years. From 1997, the age-specific incidence curve changed completely (p < 0.0001), showing an incidence peak at 60–64 years and a reduced incidence among elderly women. This incidence peak concerned mainly early stage and oestrogen positive cancers and was exclusively observed among women who ever used hormone replacement therapy, regardless whether the tumour was screen-detected or not. The increasing prevalence of hormone replacement therapy use during the 1990s could explain the important change in age-specific breast cancer incidence, not only by increasing breast cancer risk, but also by revealing breast cancer at an earlier age

Background and purpose: In this study, we investigated how often guidelines for radiation therapy in patients with breast cancer are not complied with, which patient group is mostly affected, and how this influences local recurrence. Patients and methods: All patients (n = 1,903) diagnosed between November 2003 and December 2008 with primary invasive or intraductal breast cancer in the interdisciplinary breast center of the Charite Hospital Berlin were included and followed for a median 2.18 years. Results: Patients who, in contrast to the recommendation of the interdisciplinary tumor board, did not undergo postoperative radiation experienced a fivefold higher local recurrence rate (p < 0.0005), corresponding to a 5-year locoregional recurrence-free survival of 74.5% in this group. The 5-year locoregional recurrence-free survival of patients following the recommendations was 93.3%. Guideline compliance was dependent on age of patients, acceptance of adjuvant hormonal treatment or chemotherapy, and increased diameter of the primary tumor. Multiple logistic regression analysis showed an association between compliance and age or hormonal therapy. Conclusion: In order to avoid local recurrence patients should be motivated to comply with guideline driven therapy. Since a higher number of local recurrences is observed in health services research compared to clinical research, studies on the value of adjuvant treatment following local recurrence should be performed.

Standard and Low-dose Hormone Therapy for Postmenopausal Women—Focus on the Breast

Directory of Open Access Journals (Sweden)

Peng-Hui Wang

Full Text Available Menopause occurs naturally when the ovary ceases folliculogenesis, or artificially by surgical and/or medical ablation of the ovarian function. Menopause is a hypoestrogenic state, which may adversely affect estrogen target tissues, such as the brain, skeleton and skin, as well as the cardiovascular and genitourinary systems, with resultant frequency and severity of climacteric symptoms. The climacteric symptoms, however, vary significantly among women. For decades, hormone therapy (HT has been the mainstay and is considered the most effective for managing menopausal symptoms. The prolonged use of either single estrogen therapy or a combination therapy of estrogen and progestogen (EPT might be associated with a slightly increased risk of breast cancer and many resultant adverse events, such as coronary heart disease, stroke and venous thromboembolism. Perhaps because the clear benefits are limited to these end points of HT in treating menopausal women, the relatively significant adverse event profiles of these women may not be enough to trigger primary care physicians to be more aggressive than they have been to date in treating climacteric symptoms of postmenopausal women. However, severe climacteric symptoms really disturb the woman's life. Some epidemiologic studies have shown that the increased risk for breast cancer after 5 years of combined EPT is similar in magnitude to other lifestyle variables, such as 10-year delayed menopause, fewer pregnancies and reduced breastfeeding, postmenopausal obesity, excessive alcohol or cigarette use, and lack of regular exercise. Furthermore, elevated serum concentrations of either endogenous or exogenous (replaced by HT sex hormone in either pre- or postmenopausal women are associated with an increased risk of breast cancer. Finally, the increased breast cancer risk diminishes soon after discontinuing hormones, and largely disappears by 5 years after cessation. Taken together, low-dose conventional HT

Hormone replacement therapy has been shown to reduce colorectal cancer incidence, but its effect on colorectal cancer mortality is controversial. The objective of this study was to determine the effect of hormone replacement therapy on survival from colorectal cancer. We performed a secondary analysis of data from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, a large multicenter randomized trial run from 1993 to 2001, with follow-up data recently becoming mature. Participants were women aged 55 to 74 years, without recent colonoscopy. Data from the trial were analyzed to evaluate colorectal cancer incidence, disease-specific mortality, and all-cause mortality based on subjects' use of hormone replacement therapy at the time of randomization: never, current, or former users. A total of 75,587 women with 912 (1.21%) incident colorectal cancers and 239 associated deaths were analyzed, with median follow-up of 11.9 years. Overall, 88.6% were non-Hispanic white, and colorectal cancer incidence in current users compared to never-users was lower (hazard ratio [HR], 0.81; 95% confidence interval [CI], 0.69-0.94; P = .005), as was death from colorectal cancer (HR, 0.63; 95% CI, 0.47-0.85; P = .002) and all-cause mortality (HR, 0.76; 95% CI, 0.72-0.80; P colorectal cancer incidence and improved colorectal cancer-specific survival, as well as all-cause mortality.

Broodstock management and hormonal manipulations of fish reproduction.

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

Growth hormone (GH) registries indicate that boys receive preferential GH treatment for idiopathic short stature (ISS). The aim was to determine whether age, auxological parameters, pubertal status, and target height differ between genders at GH initiation. Review of the computerized files of the endocrine department of a tertiary pediatric medical center identified 184 patients who started GH therapy for ISS between 2003-2011. Data on auxologic parameters, predicted height, parental height, and pubertal status were collected and compared between boys and girls. Boys accounted for a significantly higher percentage of the study group (65.8%, pdeficit, and pubertal status at onset of GH treatment in boys and girls suggests that gender differences do not exist. Male predominance may stem from family preferences to treat boys. Future studies are warranted to assess the psychosocial aspects in the decision to initiate therapy.

Thyroid hormone therapy following the thyroidectomy for thyroid carcinoma

International Nuclear Information System (INIS)

Horster, F.A.

1986-01-01

Medication with thyroid hormones following total thyroidectomy for thyroid carcinoma is based on the following principles: 1. The patient is informed about the lifelong necessity of taking a thyroid hormones daily before breakfast. This hormone must be given orally and its bioligical effect is identical with that of the tyhroid hormone secreted by the healthy thyroid gland. 2. The daily dosage of thyroid hormones may be assessed on the basis of the following parameters: a) the patient's clinical euthyroidism, b) suppression of thyrotropic activity, c) unrestricted tolerance of the preparation. 3. The in vitro parameters associated with optimal medication should be within the following ranges: Thyroxine value (TT4 or FT4): above the normal range, triiodothyronine value (TT3 or FT3): within the upper normal range and thyrotropin value (TSH 'ultrasensitive' or TRH-test): suppressed.

Neoadjuvant chemotherapy is an interesting option in the therapy of some breast cancer cases. Cases in which the timing for sentinel lymph node biopsy is controversial. Co-expression of estrogen receptors and Her2/neu (cc-erbB-2) in breast cancer may imply hormone resistance, especially to tamoxifen. We present a clinic case with co-expression of estrogen receptors and Her2/neu that was treated with neoadjuvant chemotherapy and previous sentinel lymph node biopsy followed by breast tumorectomy with axillar lympha- denectomy, radiotherapy and hormonotherapy with letrozol, geserelina and trastuzumab.

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.

Full Text Available Medical reviews and research comprise a key information source for news media stories on medical therapies and innovations as well as for physicians in updating their practice. The present study examined medical review journal articles, physician surveys and news media coverage of hormone replacement therapy (HT to assess the relationship between the three information sources and whether/if they contributed to a state-of-the-science gap (a condition when the evaluation of a medical condition or therapy ascertained by the highest standards of investigation is incongruent with the science-in-practice such as physician recommendations and patient actions.We content-analyzed 177 randomly sampled HT medical reviews between 2002 and 2014, and HT news valence in three major TV networks, newspapers and magazines/internet sites in 2002-2003, 2008-2009 and 2012-14. The focus in both analyses was whether HT benefits outweighed risks, risks outweighed benefits or both risks and benefits were presented. We also qualitatively content-analyzed all 19 surveys of US physicians' HT recommendations from 2002 to 2009, and 2012 to 2014.Medical reviews yielded a mixed picture about HT (40.1% benefits, 26.0% risks, and 33.9% both benefits and risks. While a majority of physician surveys were pro-HT 10/19, eight showed varied attitudes and one was negative. Newspaper and television coverage reflected a pro and con balance while magazine stories were more positive in the later reporting period.Medical journal review articles, physicians, and media reports all provide varying view points towards hormone therapy use thus leading to limited knowledge about the actual risks and benefits of HT among peri- and menopausal women and a state-of-the-science gap.

Full Text Available AimGonadal hormones are essential for reproductive function, but can act on neural and other organ systems, and are probably the cause of the large majority of known sex differences in function and disease. The aim of this review is to provide evidence for this hypothesis in relation to eye disorders and to retinopathies in particular.MethodsEpidemiological studies and research articles were reviewed.ResultsAnalysis of the biological basis for a relationship between eye diseases and hormones showed that estrogen, androgen, and progesterone receptors are present throughout the eye and that these steroids are locally produced in ocular tissues. Sex hormones can have a neuroprotective action on the retina and modulate ocular blood flow. There are differences between the male and the female retina; moreover, sex hormones can influence the development (or not of certain disorders. For example, exposure to endogenous estrogens, depending on age at menarche and menopause and number of pregnancies, and exposure to exogenous estrogens, as in hormone replacement therapy and use of oral contraceptives, appear to protect against age-related macular degeneration (both drusenoid and neurovascular types, whereas exogenous testosterone therapy is a risk factor for central serous chorioretinopathy. Macular hole is more common among women than men, particularly in postmenopausal women probably owing to the sudden drop in estrogen production in later middle age. Progestin therapy appears to ameliorate the course of retinitis pigmentosa. Diabetic retinopathy, a complication of diabetes, may be more common among men than women.ConclusionWe observed a correlation between many retinopathies and sex, probably as a result of the protective effect some gonadal hormones may exert against the development of certain disorders. This may have ramifications for the use of hormone therapy in the treatment of eye disease and of retinal disorders in particular.

Full text: Exacerbation of hyperthyroidism has been reported to occur as early as 3 days after administration of radioiodine (I-131) therapy. The hematological effects of radioiodine also have been reported but mainly confined in thyroid cancer cases wherein high doses are administered. This study was undertaken to determine the possible acute changes in the thyroid hormone concentration and blood picture of patients one week after therapy. Twelve hyperthyroid patients (8 females, 4 males), with ages ranging from 27-56 years, were followed with measurements of serum thyroid hormone levels and blood profile a week after I-131 therapy. All patients were pretreated with antithyroid medications. Radioiodine doses given ranged from 8 mCi up to 16 mCi, all based from the computed dose of 160 uCi/g. Only two out of twelve (2/12) exhibited an increase in FT3 level. Two patients showed a decrease while the remaining 8 patients showed no significant difference. Six out of 12 (50%) exhibited an increase in FT4 level. Five patients showed a decrease while only one had no significant difference. Hematologically, there were 5/12, 1/12, 3/12, 5/12 and 1/12 patients who showed a decrease in hemoglobin, hematocrit, RBC, WBC and platelet counts, respectively. Four out of 12, 2/12, and 1/12 patients, however, showed an increase in hemoglobin, RBC and platelet, respectively. The rest exhibited no significant change. FT4 level was observed to be more affected than FT3 levels but there was no consistent pattern established. A significant decrease in WBC count was observed. Although a high percentage of decreased hemoglobin was noted, no pattern was established. Radioiodine therapy caused no significant increase of serum FT3 and FT4 concentrations in the majority of patients after one week of therapy. In the followup of patients, determination of complete blood count of patients is also important. (author)

Full Text Available OBJECTIVE: To evaluate the influence of estrogen therapy and estrogen-progestin therapy on homocysteine and C-reactive protein levels in postmenopausal women. METHODS: In total, 99 postmenopausal women were included in this double-blind, randomized clinical trial and divided into three groups: Group A used estrogen therapy alone (2.0 mg of 17β-estradiol, Group B received estrogen-progestin therapy (2.0 mg of 17 β-estradiol +1.0 mg of norethisterone acetate and Group C received a placebo (control. The length of treatment was six months. Serum measurements of homocysteine and C-reactive protein were carried out prior to the onset of treatment and following six months of therapy. RESULTS: After six months of treatment, there was a 20.7% reduction in homocysteine levels and a 100.5% increase in C-reactive protein levels in the group of women who used estrogen therapy. With respect to the estrogen-progestin group, there was a 12.2% decrease in homocysteine levels and a 93.5% increase in C-reactive protein levels. CONCLUSION: Our data suggested that hormone therapy (unopposed estrogen or estrogen associated with progestin may have a positive influence on decreasing cardiovascular risk due to a significant reduction in homocysteine levels.

This study investigated changes in laboratory findings and body composition after GH recommencement for adult GHD and analyzed correlation between GH interruption period and endocrine or anthropometric parameters.MethodsA total of 45 patients (17 females and 28 males diagnosed with childhood-onset GHD (CO-GHD were investigated and all patients had organic brain lesions. Patients diagnosed CO-GHD were retested to confirm adult GHD at age 20.4±5.0 years (18.0-32.1 years. Recombinant human GH was administered at a dose of 0.44 mg/day. Clinical and laboratory parameters such as weight, height, body mass index (BMI, serum insulin-like growth factor 1 (IGF-1, serum total cholesterol, high-density lipoprotein (HDL cholesterol, low-density lipoprotein (LDL cholesterol, and triglyceride levels, were compared between baseline and 12 months after treatment using paired t-test. In addition, correlation between GH interruption period and clinical parameters including BMI, lipid profile, IGF-1, and IGFBP-3, was analyzed.ResultsOf 45 patients, 33 patients had GH interruption period of 4.3±3.6 years (0.7-12.5 years. Serum HDL-cholesterol level increased significantly, whereas LDL-cholesterol decreased after 1 year of GH replacement therapy. However, body weight and BMI showed no significant changes after 1 year of GH replacement therapy. There were no significant correlations between GH interruption period and lipid profile or anthropometric parameters.ConclusionBMI and body weight were not affected by GH replacement. However, GH replacement in adults with GHD offers benefits in lipid metabolism.

Full Text Available Background. Therapy for metastatic castration-resistant prostate cancer (CRPC is a serious problem that requires significant public health care expenditures.Objective: to evaluate the cost-effectiveness of abiraterone treatment in patients with metastatic CRPC who previously received docetaxel under the conditions of the budgetary public health system of the Russian Federation.Material and methods. Markovian simulation based on the COU-AA-301 randomized placebo-controlled Phase III study was used. Survival analysis was made in 70-year-old patients. The cost of abiraterone therapy corresponded to that of the 2013 auctions.Results. Abiraterone therapy in patients who have previously received docetaxel therapy causes an increase in average life expectancy by an average of 4.6 months and progression-free survival by 2.0 months. Moreover, the cost calculated with reference to one year of additional life will account for about 3.6 million rubles and that to one additional quality-adjusted life year will be about 5.45 million rubles.Conclusion. The cost-effectiveness of abiraterone therapy for metastatic CRPC in patients who have previously received docetaxel therapy is similar to that of other medicaments used in oncological practice under the conditions of the budgetary public health system of the Russian Federation. In this connection, abiraterone may be considered as an economically acceptable medical intervention in this clinical situation.

Full Text Available Objectives: To highlight alternative treatment options other than exogenous testosterone administration for hypogonadal men with concomitant infertility or who wish to preserve their fertility potential, as testosterone replacement therapy (TRT inhibits spermatogenesis, representing a problem for hypogonadal men of reproductive age. Materials and methods: We performed a comprehensive literature review for the years 1978–2017 via PubMed. Also abstracts from major urological/surgical conferences were reviewed. Review was consistent with the Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA criteria. We used Medical Subject Heading terms for the search including ‘testosterone replacement therapy’ or ‘TRT’ and ‘male infertility’. Results: In all, 91 manuscripts were screened and the final number used for the review was 56. All studies included were performed in adults, were written in English and had an abstract available. Conclusions: Exogenous testosterone inhibits spermatogenesis. Hypogonadal men wanting to preserve their fertility and at the same time benefiting from TRT effects can be prescribed selective oestrogen receptor modulators or testosterone plus low-dose human chorionic gonadotrophin (hCG. Patients treated for infertility with hypogonadotrophic hypogonadism can be prescribed hCG alone at first followed by or in combination from the start with follicle-stimulating hormone preparations.

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.

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.

Gynecomastia is a potential side effect of hormone therapy for prostate cancer. In large, randomized, placebo controlled studies approximately 50% or more of patients with prostate cancer experienced gynecomastia attributable to various mechanisms. Although it is mostly reported as mild to moderate, gynecomastia is one of the reasons most frequently cited for premature discontinuation of such treatment. Prophylactic radiotherapy and prophylactic tamoxifen have been shown to decrease the incidence of hormone-induced gynecomastia; nevertheless, there are still cases of refractory gynecomastia, and in these plastic surgery is needed for correction. Gynecomastia is a benign enlargement of the male breast, requiring no treatment unless it is a source of embarrassment and/or distress for the adolescent or man affected. The indications for surgical treatment of gynecomastia are founded on two main objectives: restoration of the male chest shape and diagnostic evaluation of suspected breast lesions. The authors believe that the complete circumareolar technique with no further scarring creates the best aesthetic results with fewer complications. When this is used in combination with liposuction very pleasing aesthetic results can be achieved.

Olfactory dysfunction can be an early sign of Alzheimer’s disease (AD). Since hormone replacement therapy (HRT) may protect against developing AD in postmenopausal women, the question arises as to whether it also protects against olfactory dysfunction in such women. Three olfactory and 12 neurocognitive tests were administered to 432 healthy postmenopausal women with varied HRT histories. Serum levels of reproductive hormones were obtained for all subjects; APOE-ε4 haplotype was determined for 77. National Adult Reading Test and Odor Memory/Discrimination Test (OMT) scores were positively influenced by HRT. Odor identification and OMT test scores were lower for women who scored poorly on a delayed recall test, a surrogate for mild cognitive impairment. WAIS-R NI Spatial Span Backwards Test scores were higher in women receiving estrogen plus progestin HRT and directly correlated with serum testosterone levels, the latter implying a positive effect of testosterone on spatial memory. APOE-ε4 was associated with poorer odor threshold test scores. These data suggest that HRT positively influences a limited number of olfactory and cognitive measures in the menopause. PMID:25850354

To evaluate whether hormone therapy (HT) modifies cognitive performance during sleep deprivation in postmenopausal women. Comparison was made with a group of young women. Participants included 26 postmenopausal women (age 58-72 years, 16 HT users, 10 non-users), 11 young women (age 20-26 years). They spent four consecutive nights in the sleep laboratory. Cognitive tests of attention, working memory, and verbal episodic memory were carried out after the baseline night, 25-h sleep deprivation, and recovery night. Sleep deprivation impaired performance in all groups. It was manifested either as delayed practice effect or deteriorated performance (p Attention and memory deteriorated similarly in postmenopausal and young women, despite the lower initial performance level of postmenopausal women. One night of sleep ensured recovery in most tasks.

Prostate cancer is rarely associated with leptomeningeal metastasis. An 87-year-old man with a history of prostate cancer presented with leptomeningeal metastasis. He received hormonal therapy with leuprolide. Subsequently, he achieved an impressive response, indicated by a constant fall in his PSA levels and by the stabilization of leptomeningeal disease and clinical improvement. Hormonal therapy may be effective in inducing remission in hormone-sensitive prostate cancer with leptomeningeal metastasis.

Full Text Available Abstract Background It has been shown in in-vitro experiments that "withdrawal" of tamoxifen inhibits growth of tumor cells. However, evidence is scarce when this is extrapolated into clinical context. We report our experience to verify the clinical relevance of "withdrawal therapy". Methods Breast cancer patients since 1998 who fulfilled the following criteria were selected from the departmental database and the case-notes were retrospectively reviewed: (1 estrogen receptor positive, operable primary breast cancer in elderly (age > 70 years, locally advanced or metastatic breast cancer; (2 disease deemed suitable for treatment by hormonal manipulation; (3 disease assessable by UICC criteria; (4 received "withdrawal" from a prior endocrine agent as a form of therapy; (5 on "withdrawal therapy" for ≥ 6 months unless they progressed prior. Results Seventeen patients with median age of 84.3 (53.7-92.5 had "withdrawal therapy" as second to tenth line of treatment following prior endocrine therapy using tamoxifen (n = 10, an aromatase inhibitor (n = 5, megestrol acetate (n = 1 or fulvestrant (n = 1. Ten patients (58.8% had clinical benefit (CB (complete response/partial response/stable disease ≥ 6 months with a median duration of Clinical Benefit (DoCB of 10+ (7-27 months. Two patients remain on "withdrawal therapy" at the time of analysis. Conclusion "Withdrawal therapy" appears to produce sustained CB in a significant proportion of patients. This applies not only to "withdrawal" from tamoxifen, but also from other categories of endocrine agents. "Withdrawal" from endocrine therapy is, therefore, a viable intercalating option between endocrine agents to minimise resistance and provide additional line of therapy. It should be considered as part of the sequencing of endocrine therapy.

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)

Social isolation is a major stressor which impacts the physiology, behaviour and health of individuals in gregarious species. However, depending on conditional and contextual factors, such as social status and group composition, social isolation may be perceived differently by different individuals or even by the same individuals at different times. Here we tested the effects of social status (territorial vs. non-territorial) and previous group composition (i.e. type of social group: mixed sex group with two territorial males, TT vs. mixed sex group with one territorial and one non-territorial male, TnT) on the hormonal response (androgens and cortisol) to social isolation in a cichlid fish (Oreochromis mossambicus). The different steroid hormones measured responded differentially to social isolation, and their response was modulated by social factors. Social isolation elicited a decrease of 11-keto formation only in territorial males, whereas non-territorial males present a non-significant trend for increasing KT levels. Testosterone did not respond to social isolation. Cortisol only increased in isolated individuals from TnT groups irrespective of social status (i.e. both in territorials and non-territorials). These results suggest that it is the perception of social isolation and not the objective structure of the situation that triggers the hormonal response to isolation. © 2013.

Silver-Russell Syndrome is both clinically and genetically a heterogeneous syndrome. Among the most important dysmorphic features of this condition are: a triangular shaped face with a small mandible, a prominent frontal eminence, a thin vermilion border with downward-pointing lip corners, clino- and brachydactyly of the 5th fingers as well as body asymmetry. The most well-known genetic mutations in this syndrome are: the 11p15 epimutation (20-60% patients) and the maternal uniparental chromosome 7 disomy present in 7% to 15% of patients. Children with SRS have severely impaired physical growth - intrauterine and after birth. This, together with the aforementioned dysmorphic features, forms the main diagnostic criteria. The study group consisted of 12 children treated with growth hormone, aged 2 to 17 (8.9±4.0 years), therein, all of whom met the phenotype diagnostic criteria by Wollmann and Price. The effects of growth hormone therapy on somatic development of these children are also presented. Height and weight improved as a result of growth hormone treatment, but the effects were significantly worse than in children with IUGR. Children from the study group presented also a smaller an improvement in growth velocity than children from the control group, but the difference was statistically insignificant. Growth hormone therapy accelerates the growth of children with SRS but to a smaller extent than the growth of children born with intrauterine growth retardation without dysmorphic features.

To evaluate mammographic and sonographic breast parenchymal changes and the risk of breast cancer in women on hormonal replacement therapy (HRT). The study group consisted of 50 patients examined with serial mammograms and/or ultrasonograms during HRT. The control group consisted of 50 patients examined with serial mammogram for a routine health check. Mammographic parenchymal changes in both the study and control groups and sonographic findings of 27/50 patients in study group were evaluated. Follow-up mammogram of the control group showed no interval change or slight evolution of parenchyma with increasing age, but the study group showed increasing parenchymal densities. Most frequently encountered finding on sonogram in 11 women treated by estrogen alone, was ductal dilatation (7 cases; 64%), whereas in 16 women treated by estrogen and progesteron it was ductal epithelial hyperplasia (8 cases; 50%). Overall, four breast cancers developed; one infiltrating ductal carcinoma and three ductal carcinoma in situ. HRT causes the changes of breast parenchyma on mammogram and sonogram of postmenopausal women, and increases the risk of developing breast cancer. Therefore, careful and regular examination should be followed in those on postmenopausal HRT

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.

There are different opinions about the effects of growth hormone replacement therapy (GHRT) on thyroid function and volume. This study aimed to assess the effects of GHRT on thyroid volume and function in the children and adolescents with growth hormone (GH) deficiency. A total of 29 patients diagnosed with GH deficiency were enrolled in the study. The control group consisted of 29 cases matched for age, gender and pubertal period with the patients. Thyroid function tests and insulin-like growth factor levels were measured, simultaneously thyroid volumes were assessed by ultrasonography at the initiation period and at the end of GHRT. Thyroid volumes of the patient group was -0.55±1.1 standard deviations (SDs) initially; whereas at the end of 1 year it was found to be -0.29±1.29 SDs and both SDs of thyroid volumes did not differ significantly. The SDs of thyroid volume of the control group was -0.85±1.03 SDs initially and -0.72±0.85 SDs at the end of 1 year; and they did not differ significantly. On the other hand, after GHRT of 1 year, thyroid stimulating hormone (TSH) and free thyroxine (T4) levels decreased. It was observed that SDs of thyroid gland volumes did not change in GH deficient children and adolescents after GHRT.

Toward developing recombinant gonadotropin-based hormone therapies for increasing fertility in the flatfish Senegalese sole.

Directory of Open Access Journals (Sweden)

François Chauvigné

Full Text Available Captive flatfishes, such as the Senegalese sole, typically produce very low volumes of sperm. This situation is particularly prevalent in the first generation (F1 of reared sole males, which limits the development of artificial fertilization methods and the implementation of selective breeding programs. In this study, we investigated whether combined treatments with homologous recombinant follicle-stimulating (rFsh and luteinizing (rLh hormones, produced in a mammalian host system, could stimulate spermatogenesis and enhance sperm production in Senegalese sole F1 males. In an initial autumn/winter experiment, weekly intramuscular injections with increasing doses of rFsh over 9 weeks resulted in the stimulation of gonad weight, androgen release, germ cell proliferation and entry into meiosis, and the expression of different spermatogenesis-related genes, whereas a subsequent single rLh injection potentiated spermatozoa differentiation. In a second late winter/spring trial corresponding to the sole's natural prespawning and spawning periods, we tested the effect of repeated rLh injections on the amount and quality of sperm produced by males previously treated with rFsh for 4, 6, 8 or 10 weeks. These latter results showed that the combination of rFsh and rLh treatments could increase sperm production up to 7 times, and slightly improve the motility of the spermatozoa, although a high variability in the response was found. However, sustained administration of rFsh during spawning markedly diminished Leydig cell survival and the steroidogenic potential of the testis. These data suggest that in vivo application of rFsh and rLh is effective at stimulating spermatogenesis and sperm production in Senegalese sole F1 males, setting the basis for the future establishment of recombinant gonadotropin-based hormone therapies to ameliorate reproductive dysfunctions of this species.

Effect of rejuvenation hormones on spermatogenesis.

Moss, Jared L; Crosnoe, Lindsey E; Kim, Edward D

2013-06-01

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.

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.

成人生长激素缺乏症可致机体组分改变、糖、脂代谢紊乱、骨代谢异常、心血管疾病风险增加及生活质量下降等,生长激素替代治疗可有效改善以上情况.但生长激素广泛的生理作用使其安全性备受争议,近几年大部分文献提示生长激素替代治疗不增加糖尿病的发生、肿瘤复发、新发恶性肿瘤及心血管事件等,但仍缺乏大量随机、对照研究,故在生长激素治疗时应严密监测血清胰岛素样生长因子-1水平、血脂、血压、血糖、骨密度、肿瘤标志物及生活质量等指标.%Adult growth hormone deficiency causes a series of abnormities including abnormal body composition,impaired glucose and lipid metabolism,abnormal bone metabolism,as well as increased cardiovascular risk and decreased living quality.Growth hormone replacement therapy can effectively improve those abnormalities.However,the safety of growth hormone is controversial since growth hormone has extensively physiological functions.In recent years,most of the studies revealed that the incidence of diabetes mellitus,tumor recurrence,second neoplasms and cardiovascular events in growth hormone replacement therapy did not increase,although large randomized controlled studies are needed to reach the conclusion.Serum insulin-like growth factor-1 level,serum lipids,blood pressure,plasma glucose,bone mineral density,cancer biomarkers and living quality should be closely monitored during the period of growth hormone replacement therapy.

Malignant melanoma is the 6th most commonly diagnosed cancer with increasing incidence in the United States. It is estimated that 54,200 cases of malignant melanoma will be newly diagnosed and 7,600 cases of death will occur in the United States in the year 2003 (1). At the present time, more than 1.3% of Americans will develop malignant melanoma during their lifetime (2). The average survival for patients with metastatic melanoma is about 6-9 months (3). Moreover, metastatic melanoma deposits are resistant to conventional chemotherapy and external beam radiation therapy (3). Systematic chemotherapy is the primary therapeutic approach to treat patients with metastatic melanoma. Dacarbazine is the only single chemotherapy agent approved by FDA for metastatic melanoma treatment (5). However, the response rate to Dacarbazine is only approximately 20% (6). Therefore, there is a great need to develop novel treatment approaches for metastatic melanoma. The global goal of this research program is the rational design, characterization and validation of melanoma imaging and therapeutic radiopharmaceuticals. Significant progress has been made in the design and characterization of metal-cyclized radiolabeled alpha-melanocyte stimulating hormone peptides. Therapy studies with {sup 188}Re-CCMSH demonstrated the therapeutic efficacy of the receptor-targeted treatment in murine and human melanoma bearing mice (previous progress report). Dosimetry calculations, based on biodistribution data, indicated that a significant dose was delivered to the tumor. However, {sup 188}Re is a very energetic beta-particle emitter. The longer-range beta-particles theoretically would be better for larger tumors. In the treatment of melanoma, the larger primary tumor is usually surgically removed leaving metastatic disease as the focus of targeted radiotherapy. Isotopes with lower beta-energies and/or shorter particle lengths should be better suited for targeting metastases. The {sup 177}Lu

No study on side effects had showed that conformal radiation therapy for prostate cancer is more harmful in patients older than 70 years to patients younger. The aim of this study was to evaluate acute and late toxicities of conformal radiotherapy, with high dose for localized prostate cancer in patients older than 70 years and compared to patients younger than 70 years. Between 1996 and 2009, 104 patients were treated with radiation therapy and hormonal therapy for localized cancer prostate. Median follow-up was 105 months (9 300). Acute (occurred at ≤ three months) and late side effects of 55 patients older than 70 years (median age: 75 [71 92]) were graded according to the CTCAE 3.0 criteria and compared to the younger population. Median dose to the prostate was 75.6 Gy (67 80) in both groups. There were no significant differences in acute and late side effects between age groups. For patients above 70 years, the incidence of grade II or higher acute and late side effects were respectively 27 and 22% for urologic symptoms and 13 and 16% for rectal symptoms. The frequency of grade III late symptoms was low and ranged between 0 and 6% for the evaluated symptoms, irrespective of age group. Older patients had a better biochemical recurrence-free survival than younger patients (86 versus 77% at four years, P ≡ ns). High dose 3D conformal radiotherapy for localized prostate cancer was well tolerated in patients older than 70 years. Age is not a limiting factor for conformal radiation therapy and hormonotherapy for older patients. (authors)

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

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.

Combined radio- and hormone therapy of the prostate carcinoma

Intention of this study is to detect in 49 patients suffering from prostate carcinomas, effects and side effects of radiotherapy. According to the present results, there is not any doubt that prostate carcinomas are radiosensitive. In all patients radiotherapy induced a prostate shrinkage and an increasing of consistency. It resulted that a prostate biopsy must be carried out in order to control the success of therapy. The success of the treatment depends upon tumour spreading and on its degree of differentiation. Within the observation period only in four cases metastasation of the prostate carcinoma occurred after radiotherapy. According to literature, the 5-year survival rate with an organ-defined prostate carcinoma ranges between 70 and 80% when radiotherapeutic methods are applied. The same authors indicate a 5-year survival rate between 42 and 48% for scattered carcinomas. Only minor side effects are provoked by radiotherapy. In 75% of the patients pollakisuria and dysuria resulted. After irradiation was finished, the symptoms disappeared and did not cause in any case any late complications. In 12% of the cases proctitic pain occurred during irradiation, which in 6% remained even after the treatment was terminated. We could prove unequivocally on our patients that passage impairments caused by a prostate carcinoma are improved by radiotherapy. Finally it can be said that this treatment is applicable for curing carcinoma which is localised on the prostate. In the case of an undefined, scattered carcinoma radiotherapy combined with hormone therapy is the treatment of choice. With regards to undesired side effects radiotherapy is superior to other therapeutic measures. (orig./MG) [de

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.

The objective of this paper was to determine systematically the impact of growth hormone (GH)therapy on adult height of children with (so-called) 'idiopathic short stature' (ISS) using the Cochrane Central Register of Controlled Trials, Medline, and the bibliographic references from retrieved articles of randomised controlled trials (RCTs) and non-RCTs from 1985 to April 2010. Inclusion criteria were initial short stature (defined as height >2 standard deviation[SD] below the mean), peak growth hormone responses>10 micrograms per litre (μg/L), prepuberty, no previous growth hormone therapy, and no comorbid conditions that would impair growth. Data extracted were adult height and overall gain in height from baseline measurement in childhood.Three RCTs (115 children) met the inclusion criteria.The adult height of the GH treated children exceeded that of the controls by 0.65 SD score (~4 cm). The mean height gain in treated children was 1.2 SD score compared with 0.34 SD score in untreated children. A difference of ~1.2 cm in adult height was observed between two GH dose regimens. In the seven non-RCTs, adult height of the GH-treated group exceeded that of controls by 0.45 SD score (~3 cm).The authors conclude that 1) GH therapy in children with ISS seems effective in partially reducing the deficit in height as adults, although less so than in other conditions for which GH is licensed; treated individuals remain relatively short compared with normal height peers. 2)Individual responses to therapy are highly variable; further studies are needed to identify responders. 3) High quality evidence from long-term RCTs of GH therapy that continue until adult height is necessary to determine the ideal dosage and long-term safety.

Testicular radiation dose after multimodal curative therapy for locally advanced rectal cancer. Influence on hormone levels, quality of life, and sexual functioning

Purpose: The purpose of the current work was to prospectively measure the influence of testicular radiation dose on hormone levels, quality of life (QoL), and sexual functioning following multimodal therapy (neoadjuvant radiochemotherapy, surgery, and adjuvant chemotherapy) for rectal cancer. Patients and methods: From November 2007 to November 2009, 83 male patients were treated at the University of Goettingen with radiochemotherapy (RCT) for locally advanced rectal cancer [total dose 50.4 Gy, concomitant chemotherapy with two cycles of 5-fluorouracil (FU) or 5-FU and oxaliplatin]. Testicular radiation doses were analyzed and correlated with hormone levels [luteinizing hormone (LH), follicle stimulating hormone (FSH), total testosterone and free androgen index (FAI) serum levels], QoL, and sexual functioning, which were determined before and up to 1 year after RCT. Results: Mean dose at the testes was 3.9 Gy (range 0.28-11.98 Gy). It was higher for tumors located < 6 cm from the anocutaneous line (p < 0.05). One year after therapy, testosterone, the testosterone/LH ratio, and the FAI/LH ratio were significantly decreased (3.5-3.0 μg/l, 0.9-0.4, 7.9-4.5, respectively) while LH and FSH (4.2-8.5 IU/l, 6.0-21.9 IU/l) were increased. QoL and sexual functioning were significantly impaired. However, there was no statistical correlation between testicular radiation dose and changes in hormone levels, QoL, or sexual functioning. Conclusion: Multimodal treatment for rectal cancer including RCT leads to hormone level changes and to impaired QoL and sexual functioning. However, because there was no apparent correlation between the analyzed parameters, QoL is probably also influenced by other factors, e.g., psychosocial aspects. (orig.)

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

Science.gov (United States)

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

Genetic evaluation has been recognized as an important tool to elucidate the causes of growth disorders. To investigate the cause of short stature and to determine the phenotype of patients with IHH mutations, including the response to recombinant human growth hormone (rhGH) therapy. We studied 17 families with autosomal-dominant short stature by using whole exome sequencing and screened IHH defects in 290 patients with growth disorders. Molecular analyses were performed to evaluate the potential impact of N-terminal IHH variants. We identified 10 pathogenic or possibly pathogenic variants in IHH, an important regulator of endochondral ossification. Molecular analyses revealed a smaller potential energy of mutated IHH molecules. The allele frequency of rare, predicted to be deleterious IHH variants found in short-stature samples (1.6%) was higher than that observed in two control cohorts (0.017% and 0.08%; P IHH variants segregate with short stature in a dominant inheritance pattern. Affected individuals typically manifest mild disproportional short stature with a frequent finding of shortening of the middle phalanx of the fifth finger. None of them have classic features of brachydactyly type A1, which was previously associated with IHH mutations. Five patients heterozygous for IHH variants had a good response to rhGH therapy. The mean change in height standard deviation score in 1 year was 0.6. Our study demonstrated the association of pathogenic variants in IHH with short stature with nonspecific skeletal abnormalities and established a frequent cause of growth disorder, with a preliminary good response to rhGH.

Thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are rare, representing secreting or clinically silent TSH-immunostaining pituitary tumors among all pituitary adenomas followed at their institution between 1987 and 2003. Patient records, including clinical, imaging, and pathological and surgical characteristics were reviewed. Twenty-one patients (6 women and 15 men; mean age 46 years, range 26-73 years) were identified. Of these, 10 patients had a history of clinical hyperthyroidism, of whom 7 had undergone ablative thyroid procedures (thyroid surgery/(131)I ablation) prior to the diagnosis of pituitary adenoma. Ten patients had elevated TSH preoperatively. Seven patients presented with headache, and 8 presented with visual field defects. All patients underwent imaging, of which 19 were available for imaging review. Sixteen patients had macroadenomas. Of the 21 patients, 18 underwent transsphenoidal surgery at the authors' institution, 2 patients underwent transsphenoidal surgery at another facility, and 1 was treated medically. Patients with TSH-secreting tumors were defined as in remission after surgery if they had no residual adenoma on imaging and had biochemical evidence of hypo-or euthyroidism. Patients with TSH-immunostaining tumors were considered in remission if they had no residual tumor. Of these 18 patients, 9 (50%) were in remission following surgery. Seven patients had residual tumor; 2 of these patients underwent further transsphenoidal resection, 1 underwent a craniotomy, and 4 underwent postoperative radiation therapy (2 conventional radiation therapy, 1 Gamma Knife surgery, and 1 had both types of radiation treatment). Two patients had persistently elevated TSH levels despite the lack of evidence of residual tumor. On pathological analysis and immunostaining of the surgical specimen, 17 patients had samples that stained positively for TSH, 8 for alpha-subunit, 10 for growth hormone, 7 for prolactin, 2 for adrenocorticotrophic hormone

The existence of homologous anti-human growth hormone (anti-hGH) and heterologous anti-bovine growth hormone (anti-bGH) humoral immune responses in hypopituitary patients under hGH therapy has been reported previously. In order to study the influence of the hormone source, both responses were compared by radiobinding assays performed with [ 125 I]hGH or [ 125 I]bGH as tracers. 57 hypopituitary patients treated with extractive hGH, recombinant methionyl hGH or authentic recombinant hGH were studied. A very low incidence of heterologous antibodies was found in patients under recombinant hGH therapy, contrary to the high incidence observed in patients treated with extractive hGH preparations. In addition, immunochemical studies performed with a synthetic peptide (hGH 44-128) indicated that this peptide exhibited, in the anti-bGH/[ 125 I]bGH radioimmunoassay system, higher reactivity than the native hGH, suggesting that such fragment resembled an altered conformation of the hormone. The high heterologous response elicited only by the extractive hGH along with the behaviour of the hGH 44-128 fragment supports the fact that the extraction and purification procedures in extractive preparations may alter slightly the structure of the hGH molecule and trigger a heterologous immune response. 16 refs., 4 figs., 1 tab

The extent and relevance of altered bone metabolism for statural growth in children with chronic kidney disease is controversial. We analyzed the impact of renal dysfunction and recombinant growth hormone therapy on a panel of serum markers of bone metabolism in a large pediatric chronic kidney disease cohort. Bone alkaline phosphatase (BAP), tartrate-resistant acid phosphatase 5b (TRAP5b), sclerostin and C-terminal FGF-23 (cFGF23) normalized for age and sex were analyzed in 556 children aged 6-18 years with an estimated glomerular filtration rate (eGFR) of 10-60 ml/min/1.73 m2. 41 children receiving recombinant growth hormone therapy were compared to an untreated matched control group. Standardized levels of BAP, TRAP5b and cFGF-23 were increased whereas sclerostin was reduced. BAP was correlated positively and cFGF-23 inversely with eGFR. Intact serum parathormone was an independent positive predictor of BAP and TRAP5b and negatively associated with sclerostin. BAP and TRAP5B were negatively affected by increased C-reactive protein levels. In children receiving recombinant growth hormone, BAP was higher and TRAP5b lower than in untreated controls. Sclerostin levels were in the normal range and higher than in untreated controls. Serum sclerostin and cFGF-23 independently predicted height standard deviation score, and BAP and TRAP5b the prospective change in height standard deviation score. Markers of bone metabolism indicate a high-bone turnover state in children with chronic kidney disease. Growth hormone induces an osteoanabolic pattern and normalizes osteocyte activity. The osteocyte markers cFGF23 and sclerostin are associated with standardized height, and the markers of bone turnover predict height velocity.

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 determine the influence of radical prostatectomy (RP) and external beam radiation therapy (EBRT) on the hypothalamic pituitary axis of 120 men with clinically localized prostate cancer treated with RP or EBRT exclusively. 120 patients with localized prostate cancer were enrolled. Ninety two patients underwent RP and 28 patients EBRT exclusively. We measured serum levels of luteinizing hormone, follicle stimulating hormone (FSH), total testosterone (T), free testosterone, and estradiol at baseline and at 3 and 12 months after treatment completion. Patients undergoing RP were younger and presented a higher prostate volume (64.3 vs. 71.1 years, p<0.0001 and 55.1 vs. 36.5 g, p<0.0001; respectively). No differences regarding serum hormonal levels were found at baseline. Luteinizing hormone and FSH levels were significantly higher in those patients treated with EBRT at three months (luteinizing hormone 8,54 vs. 4,76 U/l, FSH 22,96 vs. 8,18 U/l, p<0,0001) while T and free testosterone levels were significantly lower (T 360,3 vs. 414,83ng/dl, p 0,039; free testosterone 5,94 vs. 7,5pg/ml, p 0,018). At 12 months FSH levels remained significantly higher in patients treated with EBRT compared to patients treated with RP (21,01 vs. 8,51 U/l, p<0,001) while T levels remained significantly lower (339,89 vs. 402,39ng/dl, p 0,03). Prostate cancer treatment influences the hypothalamic pituitary axis. This influence seems to be more important when patients with prostate cancer are treated with EBRT rather than RP. More studies are needed to elucidate the role that prostate may play as an endocrine organ. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

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

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.

Functional hypothalamic amenorrhea (FHA) refers to a functional menstrual disorder with various causes and presentations. Recovery of menstrual cyclicity is common in long-term follow-up but the affecting factors remain unknown. To explore factors affecting the menstrual resumption and to evaluate the pituitary response to gonadotropin-releasing hormone (GnRH) in FHA. Thirty cases with FHA were recruited. All subjects were put on continuous 1 mg/day estradiol valerate orally and followed up monthly. Recovery was defined as the occurrence of at least three consecutive regular cycles. Responder referred to those who recovered within two years of therapy. Gonadotropin response to the 50 μg GnRH challenge was tested every three months. Nineteen (63.3%) subjects recovered with a mean time to recovery of 26.8 months. Time to recovery was negatively correlated with body mass index (BMI) before and by amenorrhea. Twentyone cases had undertaken therapy for more than two years and 10 of them recovered. BMI before and by amenorrhea were negatively correlated with the recovery. Significant increase of serum luteinizing hormone (LH) and LH response to GnRH were noted after recovery. Menstrual resumption was common in FHA undertaking estrogen replacement therapy (ERT). The likelihood of recovery was affected by their BMI before and by amenorrhea but not by the weight gain during therapy. Low serum LH and attenuated LH response to GnRH were the main features of pituitary deficiency in FHA. The menstrual resumption in FHA was accompanied by the recovery of serum LH and the LH response to GnRH.

Cornelia de Lange syndrome (CdLS) is a both clinically and genetically heterogeneous syndrome. In its classical form, it is characterised by distinctive facial features, intra-uterine growth retardation, short stature, developmental delay, and anomalies in multiple organ systems. NIPBL, SMC1A, SMC3, RAD21 and HDAC8, all involved in the cohesin pathway, have been identified to cause CdLS. Growth hormone (GH) secretion has been reported as normal, and to our knowledge, there are no reports on the effect of recombinant human GH treatment in CdLS patients. We present a patient born small for gestational age with persistent severe growth retardation [height -3.4 standard deviation score (SDS)] and mild dysmorphic features, who was treated with GH from 4.3 years of age onward and was diagnosed 6 years later with CdLS using whole-exome sequencing. Treatment led to a height gain of 1.6 SDS over 8 years. Treatment was interrupted shortly due to high serum insulin-like growth factor-1 serum values. In conclusion, GH therapy may be effective and safe for short children with CdLS.

Based on the previous results concerning electron transfer processes in biological substances, it was of interest to investigate if hormone transients resulting by e.g. electron emission can be regenerated. The presented results prove for the first time that the hormone transients originating by the electron emission process can be successfully regenerated by the transfer of electrons from a potent electron donor, such as vitamin C (VitC). Investigations were performed using progesterone (PRG), testosterone (TES) and estrone (E1) as representatives of hormones. By irradiation with monochromatic UV light (λ=254 nm) in a media of 40% water and 60% ethanol, the degradation as well as the regeneration of the hormones was studied with each hormone individually and in the mixture with VitC as a function of the absorbed UV dose, using HPLC. Calculated from the obtained initial yields, the determined regeneration of PRG amounted to 52.7%, for TES to 58.6% and for E1 to 90.9%. The consumption of VitC was determined in the same way. The reported results concerning the regeneration of hormones by the transfer of electrons from an electron donor offer a new, promising method for the therapy with hormones. As a consequence of the regeneration of hormones, a decreased formation of carcinogenic metabolites is expected.

Objective To compare the response in quality of life (QoL) to growth hormone (GH) replacement in women with GH deficiency (GHD) and a history of acromegaly with that in women with GHD of other causes. Methods Fifty-five women with GHD were studied: 17 with prior acromegaly and 38 with other causes of GHD. We compared two 6-month, randomized, placebo-controlled studies of GH therapy in women with hypopituitarism conducted with use of the same design—one in women with a history of acromegaly and one in women with no prior acromegaly. QoL was assessed with the following questionnaires: the QoL-Assessment of Growth Hormone deficiency in Adults (AGHDA), the Symptom Questionnaire, and the 36-Item Short-Form Health Survey (SF-36). Results The 2 groups had comparable mean pretreatment age, body mass index, and QoL scores and comparable mean GH dose at 6 months (0.61 ± 0.30 versus 0.67 ± 0.27 mg daily). After 6 months of GH replacement therapy, women with GHD and prior acromegaly demonstrated a greater improvement in AGHDA score, four SF-36 subscales (Role Limitations due to Physical Health, Energy or Fatigue, Emotional Well-Being, and Social Functioning), and the Somatic Symptoms subscale of the Symptom Questionnaire than did women with GHD of other causes. Poorer pretreatment QoL was associated with a greater improvement in QoL after administration of GH. Conclusion In this study, GH replacement therapy improved QoL in women with GHD and a history of acromegaly but not in women with GHD due to other hypothalamic and pituitary disorders. Further studies are needed to determine the long-term risks versus benefits of GH replacement in patients who develop GHD after definitive treatment for acromegaly. PMID:22440981

With the aim of evaluating the effect of high dose irradiation (6,500 cGy/36 fractions or higher) to pituitary fossa, a prospective study was carried out in patients with nasopharyngeal cancer by a serial determination of several hormones in the serum, before and after the course of radiation therapy (RT). The radiation treatment field was at least 1 cm above the skull base with bilateral parallel opposing fields. Hormone assays were performed three times on each patient: (1)prior to, (2)one month after, (3)15-18 months after radiation therapy. The study included determination of serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), cortisol, growth hormone (GH) and prolactin concentrations and LH-releasing hormone, thyrotrophin-releasing hormone stimulation and insulin tolerance tests were also carried out. Complete profiles were obtained in 24 patients (16 males and 8 females), aged 16-67 years. The results showed a significant decrease in the level of serum peak value of LH in males 18 months after therapy, and also in GH both one month and 18 months after therapy. A significant increase in the peak value of serum TSH was observed after therapy. Decreased serum FSH, cortisol and prolactin levels were noted, but these did not reach statistical significance. The decrease in GH level appeared earlier and was more sensitive than that found for the other hormones, and could prove to be a useful parameter for clinical evaluation. None of the patients showed any clinically recognizable symptoms or signs of hormone deficiency in the 18-33 months following completion of the radiation therapy. (author)

Full Text Available ABSTRACT INTRODUCTION: The difficulty in choosing the appropriate therapy for chronic tinnitus relates to the variable impact on the quality of life of affected patients and, thus, requires individualization of treatment. OBJECTIVE: To evaluate the effectiveness of using sound generators with individual adjustments to relieve tinnitus in patients unresponsive to previous treatments. METHODS: A prospective study of 10 patients with chronic tinnitus who were unresponsive to previous drug treatments, five males and five females, with ages ranging from 41 to 78 years. Bilateral sound generators (Reach 62 or Mind 9 models were used daily for at least 6 h during 18 months. The patients were evaluated at the beginning, after 1 month and at each 3 months until 18 months through acuphenometry, minimum masking level, the Tinnitus Handicap Inventory, visual analog scale, and the Hospital Anxiety and Depression Scale. The sound generators were adjusted at each visit. RESULTS: There was a reduction of Tinnitus Handicap Inventory in nine patients using a protocol with a customized approach, independent of psychoacoustic characteristics of tinnitus. The best response to treatment occurred in those with whistle-type tinnitus. A correlation among the adjustments and tinnitus loudness and minimum masking level was found. Only one patient, who had indication of depression by Hospital Anxiety and Depression Scale, did not respond to sound therapy. CONCLUSION: There was improvement in quality of life (Tinnitus Handicap Inventory, with good response to sound therapy using customized settings in patients who did not respond to previous treatments for tinnitus.

Certain relationships between pituitary size and growth hormone (GH) secretion have previously been observed, however they are still a matter of controversy. Organic abnormalities of the hypothalamic-hypophyseal region are important for predicting growth response to GH therapy. Evaluation of relations between GH secretion and the pituitary size in short children and estimation of the efficacy of GH therapy in children with GH deficiency (GHD). The analysis comprised 216 short children (159 boys). Two GH stimulation tests, as well as magnetic resonance image (MRI) examination, were performed in each patient. All the patients with GHD were treated with GH for, at least, one year. Significant correlations were found between pituitary height and GH secretion (p < 0.05). Patients were classified into three (3) groups: 1) pituitary hypoplasia (HP) for height age; 2) HP for the chronological age but not for the height age; 3) normal pituitary size. Significant differences in GH secretion were observed among the groups (6.1+/-5.3 vs. 8.1+/-4.4 vs. 12.3+/-9.1 ng/mL, respectively). There was a negative correlation between GH peak and height gain during GH therapy (r = -0.34). The highest growth improvement was noticed in patients with HP for the height age. Pituitary hypoplasia for the height age is related to more severe GH deficiency and the best response to GH therapy.

Hormone therapy (HT) has long been thought beneficial for controlling menopausal symptoms and human cognition. Studies have suggested that HT has a positive association with working memory, but no consistent relationship between HT and neural activity has been shown in any cognitive domain. The purpose of this meta-analysis was to assess the convergence of findings from published randomized control trials studies that examined brain activation changes in postmenopausal women. A systematic search for fMRI studies of neural responses during working memory tasks in postmenopausal women was performed. Studies were excluded if they were not treatment studies and did not contain placebo or blank controls. For the purpose of the meta-analysis, 8 studies were identified, with 103 postmenopausal women taking HT and 109 controls. Compared with controls, postmenopausal women who took HT increased activation in the left frontal lobe, including superior frontal gyrus (BA 8), right middle frontal gyrus (BA 9), anterior lobe, paracentral lobule (BA 7), limbic lobe, and anterior cingulate (BA 32). Additionally, decreased activation is noted in the right limbic lobe, including parahippocampal gyrus (BA 28), left parietal lobe, and superior parietal lobule (BA 7). All regions were significant at p ≤ 0.05 with correction for multiple comparisons. Hormone treatment is associated with BOLD signal activation in key anatomical areas during fMRI working memory tasks in healthy hormone-treated postmenopausal women. A positive correlation between activation and task performance suggests that hormone use may benefit working memory.

Most studies of exercise-induced amenorrhea have compared amenorrheic athletes (usually runners) with sedentary control subjects. Such comparisons will identify hormonal changes that develop as a result of exercise training but cannot determine which of these changes play a role in causing amenorrhea. To obviate this problem, we assessed reproductive hormone status in a group of five amenorrheic runners and compared them to a group of six eumenorrheic runners matched for body fatness, training intensity, and exercise performance. Compared to the eumenorrheic runners, the amenorrheic runners had lower serum estradiol concentrations, similar basal serum luteinizing hormone and follicle-stimulating hormone concentrations, and exaggerated responses of serum gonadotropins after administration of luteinizing hormone-releasing hormone (100 micrograms intravenous bolus). Serum prolactin levels, both basally and after thyrotropin-releasing hormone administration (500 micrograms intravenous bolus) or treadmill exercise, was similar in the two groups, as were serum thyroid function tests (including thyrotropin response to thyrotropin-releasing hormone). Changes in serum cortisol levels after short-term treadmill exercise were similar in both groups, and serum testosterone levels increased after exercise only in the eumenorrheic group. In neither group did such exercise change serum luteinizing hormone, follicle-stimulating hormone, or thyrotropin levels. We concluded that exercise-induced amenorrhea is not solely related to the development of increased prolactin output after exercise training. The exaggerated gonadotropin response to luteinizing hormone-releasing hormone seen in amenorrheic runners in comparison with matched eumenorrheic runners is consistent with a hypothalamic etiology for the menstrual dysfunction, analogous to that previously described in "stress-induced" or "psychogenic" amenorrhea.

To determine the effect of GnRH analogues (GnRH-a) leuprolide acetate (LA) and cetrorelix acetate on gonadal hormone-regulated expression of extracellular matrix in uterine leiomyoma three-dimensional (3D) cultures. Laboratory study. University research laboratory. Women undergoing hysterectomy for symptomatic leiomyomas. The 3D cell cultures, protein analysis, Western blot, immunohistochemistry. Expression of extracellular matrix proteins, collagen 1, fibronectin, and versican in leiomyoma cells 3D cultures exposed to E2, P, LA, cetrorelix acetate, and combinations for 24- and 72-hour time points. The 3D leiomyoma cultures exposed to E2 for 24 hours demonstrated an increased expression of collagen-1 and fibronectin, which was maintained for up to 72 hours, a time point at which versican was up-regulated significantly. Although P up-regulated collagen-1 protein (1.29 ± 0.04) within 24 hours of exposure, significant increase in all extracellular matrix (ECM) proteins was observed when the gonadal hormones were used concomitantly. Significant decrease in the amount of ECM proteins was observed on use of GnRH-a, LA and cetrorelix, with 24-hour exposure. Both the compounds also significantly decreased ECM protein concentration despite the presence of E2 or both gonadal hormones. This study demonstrates that GnRH-a directly affect the gonadal hormone-regulated collagen-1, fibronectin, and versican production in their presence. These findings suggest that localized therapy with GnRH-a may inhibit leiomyoma growth even in the presence of endogenous gonadal hormone exposure, thereby providing a mechanism to eliminate the hypoestrogenic side effects associated with GnRH-a therapy.

Different symptoms in Climacteric period, includes hot flash. Hormone replacement therapy (HRT) is common therapy for relief of menopausal symptoms but has possible contraindications and side effects. Recently Piascledine (combination of Avocado oil with Soybean oil) showed effects in reducing hot flash severity. Present study designed to compare the effects of HRT with Piascledine in treatment of hot flash. The cases of this study were sixty-six women at the age range of 40 to 70 years and complaints of menopause-induced hot flashing, whose last menstruation dated at least 6 months prior to the beginning of the study. The patients in this open label clinical trial, randomized to receive Piascledine capsule 1 mg or HRT (0.625 mg oral daily Conjugated Estrogen tablets, plus 2.5 mg continuous oral daily Medroxyprogesterone Acetate tablets) for 2 month. Hot flash property and severity was assessed via a daily check list and Visual analog scale. Climacteric symptom was measured before and after intervention using Greene Climacteric Scale (GCS) and Blatt-kupperman Menopausal Index (BKMI). Thirty-three eligible patients were allocated in each group. From the Piascledine group, one patient and from the HRT group, 16 patients weren›t willing to attend the study; therefore, 32 and 17 woman received treatment in Piascledine and HRT groups. 4 patients were withdrawn for vaginal bleeding and one for breast tenderness from HTR group. Hot flash severity in both groups decreased during the time similarly. With regard to GCS (p = 0.571) and BMKI (p = 0.891), the outcome was similar among the two groups. Due to low HRT compliance and its possible risks in long period of time and considering the same activity of soybean supplement and HRT in relieving the hot flash as menopausal symptoms in women, it seems that soybean supplements can be an alternative therapy to hormone.

The use of aggregated quality of life estimates in the formation of public policy and practice guidelines raises concerns about the moral relevance of variability in values in preferences for health care. This variability may reflect unique and deeply held beliefs that may be lost when averaged with the preferences of other individuals. Feminist moral theories which argue for attention to context and particularity underline the importance of ascertaining the extent to which differences in preferences for health states reveal information which is morally relevant to clinicians and policymakers. To facilitate these considerations, we present an empirical study of preferences for the timing and occurrence of health states associated with hormone replacement therapy (HRT). Sixteen women between the ages of 45 and 55 were enrolled in this pilot study. Their preferences regarding five health states associated with HRT (menopausal symptoms. side effects of HRT, breast cancer, myocardial infarction, and osteoporosis) were assessed in quantitative terms known as utilities. Two standard methods, the visual analog scale (VAS) and the standard gamble (SG), were used to assess utility and time preference (calculated as a discount rate). The wide variability of responses underlines the importance of tailoring health care to individual women's preferences. Policy guidelines which incorporate utility analysis must recognize the normative limitations of aggregated preferences, and the moral relevance of individual conceptions of health.

Silent pituitary adenomas are a subtype of adenomas characterized by positive immunoreactivity for one or more hormones classically secreted by normal pituitary cells but without clinical expression, although in some occasions enhanced or changed secretory activity can develop over time. Silent corticotroph adenomas are the classical example of this phenomenon. A series of about 500 pituitary adenomas seen over a period of 20 years were screened for modification in hormonal secretion. Biochemical and immunohistochemical data were reviewed. Two cases were retrieved, one silent somatotroph adenoma and one thyrotroph adenoma, both without specific clinical features or biochemical abnormalities, which presented 20 years after initial surgery with evidence of acromegaly and hyperthyroidism, respectively. While the acromegaly was controlled by a combination of somatostatin analogs and growth hormone (GH) receptor antagonist therapy, neurosurgery was necessary to manage the thyrotroph adenoma. Immunohistochemical examination demonstrated an increase in the number of thyroid stimulating hormone (TSH)-immunoreactive cells compared to the first tissue. Apparently, the mechanisms responsible for the secretory modifications are different, being a change in secretory capacity in the silent somatotroph adenoma and a quantitative change in the silent thyrotroph adenoma. These two cases, one somatotroph and one thyrotroph adenoma, are an illustration that clinically silent pituitary adenomas may in rare circumstances evolve over time and become active, as previously demonstrated in silent corticotroph adenomas.

Gene expression studies on human keratinocytes transduced with human growth hormone gene for a possible utilization in gene therapy

Taking advantage of the recent progress in the DNA-recombinant techniques and of the potentiality of normal human keratinocytes primary culture to reconstitute the epidermis, it was decided to genetically transform these keratinocytes to produce human growth hormone under controllable conditions that would be used in gene therapy at this hormone deficient patients. The first step to achieve this goal was to standardize infection of keratinocytes with retrovirus producer cells containing a construct which included the gene of bacterial b-galactosidase. The best result was obtained cultivating the keratinocytes for 3 days in a 2:1 mixture of retrovirus producer cells and 3T3-J2 fibroblasts irradiated with 60 Gy, and splitting these infected keratinocytes on 3T3-J2 fibroblasts feeder layer. Another preliminary experiment was to infect normal human keratinocytes with interleukin-6 gene (hIL-6) that, in pathologic conditions, could be reproduced by keratinocytes and secreted to the blood stream. Thus, we verify that infected keratinocytes secrete an average amount of 500 ng/10 6 cell/day of cytokin during the in vitro life time, that certify the stable character of the injection. These keratinocytes, when grafted in mice, secrete hIL-6 to the blood stream reaching levels of 40 pg/ml of serum. After these preliminary experiments, we construct a retroviral vector with the human growth hormone gene (h GH) driven by human metallothionein promoter (h PMT), designated DChPMTGH. Normal human keratinocytes were infected with DChPMTGH producer cells, following previously standardized protocol, obtaining infected keratinocytes secreting to the culture media 340 ng h GH/10 6 cell/day without promoter activation. This is the highest level of h GH secreted in human keratinocytes primary culture described in literature. The h GH value increases approximately 10 times after activation with 100 μM Zn +2 for 8-12 hours. (author). 158 refs., 42 figs., 6 tabs

Gynecological problems are one of the most frequent somatic complications of eating disorders. The purpose of the present study was to assess the role of improper eating habits causing menstrual disturbances, anovulation and related hormonal changes. Latent bulimia nervosa is in the focus of attention since amenorrhea is considered as a diagnostic criterion of anorexia nervosa. Subjects of the BITE (Bulimia Investigation Test, Edinburgh) test were infertile patients (n = 34) of the gynecological outpatient departments after medical examination, blood-test (LH, FSH, androstenedione, DHEAS, progesterone, testosterone, SHBG, prolactin) and ultrasonic examination (uterus and ovaries). Symptoms and severity subscales of the BITE test and body mass index (BMI) were close correlation (p = 0.003, p = 0.033). In comparison with previous results, EDNOS (Eating Disorders Not Otherwise Specified) prevalence was 48%. Of hormonal changes, low LH and FSH levels (6/6) and hyperandrogenism (5/6) were significant in patients with subclinical eating disorders (n = 6) by infertile women as compared with the "normal" infertile group (n = 18; 7/18, 8/18). The recent results suggests that unsatisfactory nutrition (bulimic binges, "crash diet") is as relevant in hormonal dysfunction, menstrual disturbances and infertility as pathologically low weight in anorexia nervosa. Excessive application of contraceptives in therapy has to be taken into consideration.

The menopause accelerates bone loss and is associated with an increased bone turnover. Bone formation may be evaluated by several biochemical markers. However, the establishment of an accurate marker for bone resorption has been more difficult to achieve. To study the effect of hormone replacement therapy (HRT) on bone mass and on the markers of bone resorption: urinary excretion of pyridinoline and deoxypyridinoline. Cohort correlational study. Academic referral center. 53 post-menopausal women, aged 48-58 years. Urinary pyr and d-pyr were measured in fasting urine samples by spectrofluorometry after high performance liquid chromatography and corrected for creatinine excretion measured before treatment and after 1, 2, 4 and 12 months. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry (DEXA) before treatment and after 12 months of HRT. The BMD after HRT was about 4.7% (P < 0.0004); 2% (P < 0.002); and 3% (P < 0. 01) higher than the basal values in lumbar spine, neck and trochanter respectively. There were no significant correlations between pyridinium cross-links and age, weight, menopause duration and BMD. The decrease in pyr and d-pyr was progressive after HRT, reaching 28.9% (P < 0.0002), and 42% (P < 0.0002) respectively after 1 year. Urinary pyridinoline and deoxypyridinoline excretion decreases early in hormone replacement therapy, reflecting a decrease in the bone resorption rate, and no correlation was observed with the bone mass evaluated by densitometry.

Full Text Available Abstract Background Patients with high Gleason score, elevated prostate specific antigen (PSA level, and advanced clinical stage are at increased risk for both local and systemic relapse. Recent data suggests higher radiation doses decrease local recurrence and may ultimately benefit biochemical, metastasis-free and disease-specific survival. No randomized data is available on the benefits of long-term hormonal therapy (HT in these patients. A prospective study on the efficacy and safety of trimodality treatment consisting of HT, external beam radiation therapy (EBRT, and brachytherapy (BT for high-risk prostate cancer (PCa is strongly required. Methods/Design This is a phase III, multicenter, randomized controlled trial (RCT of trimodality with BT, EBRT, and HT for high-risk PCa (TRIP that will investigate the impact of adjuvant HT following BT using iodine-125 (125I-BT and supplemental EBRT with neoadjuvant and concurrent HT. Prior to the end of September 2012, a total of 340 patients with high-risk PCa will be enrolled and randomized to one of two treatment arms. These patients will be recruited from more than 41 institutions, all of which have broad experience with 125I-BT. Pathological slides will be centrally reviewed to confirm patient eligibility. The patients will commonly undergo 6-month HT with combined androgen blockade (CAB before and during 125I-BT and supplemental EBRT. Those randomly assigned to the long-term HT group will subsequently undergo 2 years of adjuvant HT with luteinizing hormone-releasing hormone agonist. All participants will be assessed at baseline and every 3 months for the first 30 months, then every 6 months until 84 months from the beginning of CAB. The primary endpoint is biochemical progression-free survival. Secondary endpoints are overall survival, clinical progression-free survival, disease-specific survival, salvage therapy non-adaptive interval, and adverse events.

Cardiovascular consequences of hormone therapy in postmenopausal women: Messages to clinicians.

Ylikorkala, O; Mikkola, T

Results from the recent randomized clinical trials indicating that hormone therapy (HT) does not provide cardiovascular protection, but potentially harm are in profound disagreement with the sound evidence from numerous observational and experimental studies. While the observational studies have mainly assessed symptomatic recently menopausal women, the randomized trials have studied symptomless elderly postmenopausal women with established coronary heart disease or various risk factors for cardiovascular disease. Therefore, the recent trials have only revealed that HT does not provide secondary cardiovascular benefits. Since primary cardiovascular benefits of HT are rational but not yet proven in clinical trials, new studies are in demand. Until more data from recently menopausal symptomatic women are available, we need to base our decisions on existing evidence and good clinical practice. Although the potential of HT to provide cardiovascular benefits is decreased by advancing age and time since menopause, this should not preclude the use of individualized HT in younger postmenopausal women.

Radiotherapy and hormone therapy in intermediate risk prostate cancer: a critical review

International Nuclear Information System (INIS)

Franco, Rejane Carolina; Souhami, Luis

2015-01-01

Introduction: The standard treatment for patients with high risk prostate cancer is the combined use of radiation therapy (RT ) and hormone therapy (HT). In regards to patients stratified as intermediate risk, the use of HT associated with RT remains controversial, and its use should be carefully planned and based on available evidence. Objective: To critically assess results of randomized studies published in the literature that associated the use of HT of short duration with an average period of 6 months with RT in the treatment of patients with localized prostate cancer classified as intermediate risk. Method: Only randomized studies comparing these treatments were eligible for this review. A structured search through 'PubMed' was carried out using the terms 'androgen suppression therapy', 'radiotherapy', 'randomized trials', 'phase 3 trials', 'prostate cancer' and 'intermediate risk'. Results: Four randomized studies comparing RT alone to RT plus short course HT were found and selected. The majority of the trials had a mixed population of intermediate and high risk disease and did not include patients with only intermediate risk. Despite that, there appears to be a significant benefit for the combined approach regarding disease-free survival, biochemical free survival and overall survival. Conclusion: The randomized studies published so far suggest improved outcomes for the group of patients receiving RT and short course HT. Data from randomized trials comparing RT alone to RT and short course HT in patients with intermediate risk only are forthcoming. (author)

Menopause impacts 25 million women world wide each year, and the World Health Organization estimates 1.2 billion women will be postmenopausal by 2030. Menopause has been associated with symptoms of hot flashes, night sweats, dysphoric mood, sleep disturbance, and conditions of cardiovascular disease, depression, osteoporosis, osteoarthritis, depression, dementia, and frailty. Conventional hormone replacement therapy results in increased thrombotic events, and an increased risk of breast cancer and dementia as evidenced in large prospective clinical trials including Heart and Estrogen/Progestin Replacement Study I and the Women's Health Initiative. A possible mechanism for these adverse events is the unfavorable net effects of conjugated equine estrogens and medroxyprogesterone acetate on the hemostatic balance and inflammatory and immune factors. Physiologic sex steroid therapy with transdermal delivery for peri/postmenopausal women may offer a different risk/benefit profile, yet long-term studies of this treatment model are lacking. The objective of this study was to examine the long-term effects of compounded bioidentical transdermal sex steroid therapy including estriol, estradiol, progesterone, DHEA, and testosterone on cardiovascular biomarkers, hemostatic, inflammatory, immune signaling factors; quality-of-life measures; and health outcomes in peri/postmenopausal women within the context of a hormone restoration model of care. A prospective, cohort, closed-label study received approval from the Human Subjects Committee. Recruitment from outpatient clinics at an academic medical center and the community at large resulted in three hundred women giving signed consent. Seventy-five women who met strict inclusion/exclusion criteria were enrolled. Baseline hormone evaluation was performed along with baseline experimental measures. Following this, women received compounded transdermal bioidentical hormone therapy of BiEst (80%Estriol/20%Estradiol), and

Recombinant human thyroid-stimulating hormone (rhTSH) enhances {sup 131}I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi {sup 131}I, in patients with MNG. Seventeen patients (15 females, 59.0 {+-} 13.1 years), who had never been submitted to {sup 131}I therapy, received a single 0.1-mg injection of rhTSH followed by 30 mCi {sup 131}I on the next day. Mean basal thyroid volume measured by computed tomography was 106.1 {+-} 64.4 mL. {sup 131}I 24-h uptake, TSH, free-T4, T3, thyroglobulin, anti-thyroid antibodies, and thyroid volume were evaluated at regular intervals of 12 months. Mean {sup 131}I 24-h uptake increased from 18.1 {+-} 9.7 to 49.6 {+-} 13.4% (P < 0.001), a median 2.6-fold increase (1.2 to 9.2). Peak hormonal levels were 10.86 {+-} 5.44 mU/L for TSH (a median 15.5-fold increase), 1.80 {+-} 0.48 ng/dL for free-T4, 204.61 {+-} 58.37 ng/dL for T3, and a median of 557.0 ng/mL for thyroglobulin. The adverse effects observed were hyperthyroidism (17.6%), painful thyroiditis (29.4%) and hypothyroidism (52.9%). Thyroid volume was reduced by 34.3 {+-} 14.3% after 6 months (P < 0.001) and by 46.0 {+-} 14.6% after 1 year (P < 0.001). Treatment of MNG with a single 0.1-mg dose of rhTSH, followed by a fixed amount of radioactivity of {sup 131}I, leads to an efficacious decrease in thyroid volume for the majority of the patients, with a moderate incidence of non-serious and readily treatable adverse effects.

Full Text Available The present study evaluated the short-term effects of percutaneous 17ß-estradiol on blood pressure, metabolic profile and hormonal levels in postmenopausal women with systemic arterial hypertension. After a wash-out period of 15 days, 10 hypertensive patients were treated with guanabenz acetate to control blood pressure, followed by 17ß-estradiol in the form of hydroalcoholic gel administered for 21 of 28 days of each cycle, for 3 cycles. Patients were evaluated before, during and 2 months after estrogen administration. Systolic and diastolic blood pressure or heart rate did not present any significant change in any patient when compared to those periods with the antihypertensive drug only (pretreatment period and 60 days after estrogen therapy was discontinued. Plasma biological markers of hepatic estrogenic action (plasma renin activity, antithrombin III, triglycerides, total cholesterol and lipoproteins also remained unchanged during the study. Hormone treatment was effective, as indicated by the relief of menopausal symptoms, a decrease in FSH levels (73.48 ± 27.21 to 35.09 ± 20.44 IU/l, P<0.05, and an increase in estradiol levels (15.06 ± 8.76 to 78.7 ± 44.6 pg/ml, P<0.05. There was no effect on LH (18.0 ± 9.5 to 14.05 ± 8.28 IU/l. Hormone levels returned to previous values after estrogen treatment was discontinued. The data indicate that short-term percutaneous 17ß-estradiol replacement therapy, at the dose used, seems to be a safe hormone therapy for hypertensive menopausal women. Nevertheless, a controlled, prospective, randomized clinical assay with a larger number of subjects is needed to definitely establish both the beneficial and harmful effects of hormone replacement therapy in hypertensive women

Full Text Available Introduction: Obviously, long therapy time of orthodontic treatment and a number of its adverse effects, such as pain, root resorption, enamel demineralization, periodontal disease, are the main reasons of complaints from patients. It is the first thing for an orthodontist to shorten the period of treatment and decrease the complications of orthodontic treatment as much as possible. The Hypothesis: We hypothesis Gonadotropin Releasing Hormone Agonists (GnRHa and add-back therapy can create the "therapeutic window", namely, the appropriate estrogen level and assuage the adverse effects of estrogen deficiency which should be avoided as much as possible. Evaluation of the Hypothesis: It is generally acknowledged that estrogen has direct regulating role in bone metabolism by acting on osteoblasts and osteoclasts. Estrogen deficiency can increase the rate of orthodontic tooth movement and also bring about some adverse effects. The appropriate estrogen level, which we call the "therapeutic window" in orthodontic treatment, can speed up the orthodontic tooth movement and eliminate the adverse effects as far as possible. GnRHa can be the maker of estrogen deficiency; meanwhile, add-back therapy can remove the adverse effects by estrogen deficiency. So, we believe that GnRHa plus add-back therapy could be a new adjuvant method of orthodontic treatment and be good for orthodontists and patients.

The impact of hormone therapy use on late-life anxiety disorder in elderly women has not been evaluated. Anxiety disorders were evaluated in 838 community-dwelling postmenopausal women aged 65 years and over, randomly recruited from electoral rolls. Anxiety disorders were assessed using a standardized psychiatric examination based on DSM-IV criteria, at baseline and as part of the 2- and 4-year follow-up. Multivariate logistic regression analyses adjusted for socio-demographic variables, measures of physical health and cognitive impairment, as well as current depressive symptomatology indicated no significant association between hormone therapy and anxiety disorders at baseline or after the 4-year follow-up period, regardless of type of treatment. Compared to women who have never taken hormonal therapy, no significant difference was observed for women taking continuously hormone therapy over the follow-up or those who stopped their treatment. The use of hormone therapy was not associated with improved anxiety symptomatology in elderly postmenopausal women.

Purpose Docetaxel added to androgen-deprivation therapy (ADT) significantly increases the longevity of some patients with metastatic hormone-sensitive prostate cancer. Herein, we present the outcomes of the CHAARTED (Chemohormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer) trial with more mature follow-up and focus on tumor volume. Patients and Methods In this phase III study, 790 patients with metastatic hormone-sensitive prostate cancer were equally randomly assigned to receive either ADT in combination with docetaxel 75 mg/m 2 for up to six cycles or ADT alone. The primary end point of the study was overall survival (OS). Additional analyses of the prospectively defined low- and high-volume disease subgroups were performed. High-volume disease was defined as presence of visceral metastases and/or ≥ four bone metastases with at least one outside of the vertebral column and pelvis. Results At a median follow-up of 53.7 months, the median OS was 57.6 months for the chemohormonal therapy arm versus 47.2 months for ADT alone (hazard ratio [HR], 0.72; 95% CI, 0.59 to 0.89; P = .0018). For patients with high-volume disease (n = 513), the median OS was 51.2 months with chemohormonal therapy versus 34.4 months with ADT alone (HR, 0.63; 95% CI, 0.50 to 0.79; P OS benefit was observed (HR, 1.04; 95% CI, 0.70 to 1.55; P = .86). Conclusion The clinical benefit from chemohormonal therapy in prolonging OS was confirmed for patients with high-volume disease; however, for patients with low-volume disease, no OS benefit was discerned.

Purpose: Males treated with irradiation (RT) or certain chemotherapeutic (CT) agents are at risk for testicular damage in the form of germ cell injury and hormonal dysfunction. Sperm DNA structural defects or immaturity may affect reproductive potential both in terms of the likelihood for conception and early fetal loss. Preclinical data provoked our hypothesis that patients with subnormal sperm counts due to cytotoxic therapy could be demonstrated to have defective sperm chromatin; we also questioned whether structural abnormalities might be found in the sperm of patients with normal counts. Although the RT dose threshold for ablation of spermatogenesis is known to be below that for hormonal dysfunction, the relative effects of CT are unclear, which suggested the second component of our investigation. Methods: Eligibility criteria included treatment with CT including an alkylating agent, and/or RT with scattered dose to the testes for a cancer not involving the testes, and remission duration of at least 3 years. Of the 15 study patients, 12 received CT (including cyclophosphamide in 7) and 12 received RT (with peripheral testicular doses of 0-169 cGy, and including 4 also treated to the whole brain with doses below that associated with impaired gonadotropin secretion). Sperm number, motility, morphology and pattern of movement were assessed by computer-assisted spermanalysis, and for chromatin structural integrity and maturation using dual parameter flow cytometric (FC) analysis of acid-induced DNA denaturation. The mean age at tumor diagnosis was 14.4 yrs (range 6.5-36; 12 patients were ≤ 19 years old), and at testing was 25.5 yrs (range 18-46), with a mean interval of 9.7 yrs (range 3-21). Results: Only 3 patients (20%) had normal sperm counts (> 20 million/ml), 2 of whom had not received an alkylating agent but had scattered RT testes doses of 41 cGy and 169 cGy, respectively. These 2 patients had impaired sperm motility (13% and 32%, respectively), and the

Full Text Available Introduction. Endocrine therapy (ET is an integral part of breast cancer (BC treatment with surgical resection remaining the cornerstone of curative treatment. The objective of this study is to compare the survival of elderly postmenopausal women with hormone receptor-positive early-stage BC treated with ET alone, without radiation or chemotherapy, versus ET plus surgery. Materials and Methods. This is a retrospective study based on a prospective database. The medical records of postmenopausal BC patients referred to the surgical oncology service of two hospitals during an 8-year period were reviewed. All patients were to receive ET for a minimum of four months before undergoing any surgery. Results. Fifty-one patients were included and divided in two groups, ET alone and ET plus surgery. At last follow-up in exclusive ET patients (n=28, 39% had stable disease or complete response, 22% had progressive disease, of which 18% died of breast cancer, and 39% died of other causes. In surgical patients (n=23, 78% were disease-free, 9% died of recurrent breast cancer, and 13% died of other causes. Conclusions. These results suggest that surgical resection is beneficial in this group and should be considered, even for patients previously deemed ineligible for surgery.

Full Text Available CONTEXT: The menopause accelerates bone loss and is associated with an increased bone turnover. Bone formation may be evaluated by several biochemical markers. However, the establishment of an accurate marker for bone resorption has been more difficult to achieve. OBJECTIVE: To study the effect of hormone replacement therapy (HRT on bone mass and on the markers of bone resorption: urinary excretion of pyridinoline and deoxypyridinoline. DESIGN: Cohort correlational study. SETTING: Academic referral center. SAMPLE: 53 post-menopausal women, aged 48-58 years. MAIN MEASUREMENTS: Urinary pyr and d-pyr were measured in fasting urine samples by spectrofluorometry after high performance liquid chromatography and corrected for creatinine excretion measured before treatment and after 1, 2, 4 and 12 months. Bone mineral density (BMD was measured by dual energy X-ray absorptiometry (DEXA before treatment and after 12 months of HRT. RESULTS: The BMD after HRT was about 4.7% (P < 0.0004; 2% (P < 0.002; and 3% (P < 0.01 higher than the basal values in lumbar spine, neck and trochanter respectively. There were no significant correlations between pyridinium cross-links and age, weight, menopause duration and BMD. The decrease in pyr and d-pyr was progressive after HRT, reaching 28.9% (P < 0.0002, and 42% (P < 0.0002 respectively after 1 year. CONCLUSIONS: Urinary pyridinoline and deoxypyridinoline excretion decreases early in hormone replacement therapy, reflecting a decrease in the bone resorption rate, and no correlation was observed with the bone mass evaluated by densitometry.

Purpose: We evaluated the effect of three-dimensional conformal radiation therapy (3D-CRT) with or without hormonal therapy (HT) on sexual function (SF) in prostate cancer patients whose SF was known before all treatment. Methods and Materials: Between March 1996 and March 1999, 144 patients received 3D-CRT (median dose = 70.2 Gy, range 66.6-79.2 Gy) for prostate cancer and had pre- and post-therapy SF data. All SF data were obtained with the O'Leary Brief SF Inventory, a self-administered, multidimensional, validated instrument. We defined total sexual potency as erections firm enough for penetration during intercourse. Mean follow-up time was 21 months (SD ± 11 months). The Wilcoxon signed-rank test was used to test for significance of the change from baseline. Results: Before 3D-CRT, 87 (60%) of 144 men were totally potent as compared to only 47 (47%) of 101 at 1-year follow-up. Of the 60 men totally potent at baseline and followed for at least 1 year, 35 (58%) remained totally potent. These changes corresponded to a significant reduction in SF (p<0.05). Patients who had 3D-CRT alone were more likely to be totally potent at 1 year than those receiving 3D-CRT with HT (56% vs. 31%, p=0.012); however, they were also more likely to be potent at baseline (71% vs. 44%, p=0.001). Although these two groups had a significant reduction in SF from baseline, their change was not significantly different from each other. Conclusion: These data indicate that 3D-CRT causes a significant reduction in total sexual potency as compared to pretreatment baseline. The addition of HT does not appear to increase the risk of sexual dysfunction

Conventional glucocorticoid replacement therapy in patients with Addison's disease (AD) is unphysiological with possible adverse effects on mortality, morbidity and quality of life. The diurnal cortisol profile can likely be restored by continuous subcutaneous hydrocortisone infusion (CSHI). The aim of this study was to compare circadian hormone rhythms and insulin sensitivity in conventional thrice-daily regimen of glucocorticoid replacement therapy with CSHI treatment in patients with AD. An open, randomized, two-period, 12-week crossover multicentre trial in Norway and Sweden. Ten Norwegian patients were admitted for 24-h sampling of hormone profiles. Fifteen Swedish patients underwent euglycaemic-hyperinsulinaemic clamp. Thrice-daily regimen of oral hydrocortisone (OHC) and CSHI treatment. We measured the circadian rhythm of cortisol, adrenocorticotropic hormone (ACTH), growth hormone (GH), insulin-like growth factor-1, (IGF-1), IGF-binding protein-3 (IGFBP-3), glucose, insulin and triglycerides during OHC and CSHI treatment. Euglycaemic-hyperinsulinaemic clamp was used to assess insulin sensitivity. Continuous subcutaneous hydrocortisone infusion provided a more physiological circadian cortisol curve including a late-night cortisol surge. ACTH levels showed a near normal circadian variation for CSHI. CSHI prevented a continuous decrease in glucose during the night. No difference in insulin sensitivity was observed between the two treatment arms. Continuous subcutaneous hydrocortisone infusion replacement re-established a circadian cortisol rhythm and normalized the ACTH levels. Patients with CSHI replacement had a more stable night-time glucose level compared with OHC without compromising insulin sensitivity. Thus, restoring night-time cortisol levels might be advantageous for patients with AD. © 2015 John Wiley & Sons Ltd.

To assess the 1-year continuation rate of HRT prescribed in Hong Kong public health sector and to identify factors affecting this continuation rate. All women who received at least one dispensed prescription of estrogens between January 1998 and December 2000 from 36 specialist outpatient clinics of the Hospital Authority were selected, and observed for at least 2 years and at most 3 years. The duration of use and variables including age, types of hormones, routes of delivery, dose of estrogen, and prescribing specialty were retrieved from the central prescription database of the Hospital Authority. Of 12,711 incident users of HRT, more than half were aged 50-59. Most (78.5%) of the users took conjugated equine estrogens (CEE) 0.625 mg or related products. Only a small proportion (3.0%) of women used CEE 0.3 mg. Initial estrogen prescriptions were written by gynaecologists in 86.7%. The overall 1-year continuation rate was 68.3%. The highest and lowest continuation rates were observed in women aged 40-49 and the two extreme age groups (35-39 and 70-79), respectively. Better continuation rate was observed in women taking estrogen-only therapy such as CEE or estradiol (overall 76.3%) than in women using continuous combined therapy (58.6%), sequential combined therapy (64.8%), or transdermal estrogen (60.6%). In the age group 60-69, the use of CEE 0.3 mg was associated with better continuation rate than CEE 0.625 mg. Better continuation rate at 1 year was associated with age younger than 60, oral route of HRT and hysterectomy.

To examine whether the effect of postmenopausal hormone therapy (HT) on brain volumes in women aged 65-79 years differs depending on type 2 diabetes status during postintervention follow-up of a randomized controlled clinical trial. The Women's Health Initiative randomized clinical trials assigned women to HT (0.625 mg/day conjugated equine estrogens with or without 2.5 mg/day medroxyprogesterone acetate) or placebo for an average of 5.6 years. A total of 1,402 trial participants underwent brain MRI 2.4 years after the trials; these were repeated in 699 women 4.7 years later. General linear models were used to assess the interaction between diabetes status and HT assignment on brain volumes. Women with diabetes at baseline or during follow-up who had been assigned to HT compared to placebo had mean decrement in total brain volume of -18.6 mL (95% confidence interval [CI] -29.6, -7.6). For women without diabetes, this mean decrement was -0.4 (95% CI -3.8, 3.0) (interaction p=0.002). This interaction was evident for total gray matter (pNeurology.

To investigate the effect of duration, how recently it has been used, and age at start of hormone replacement therapy (HRT) and the risk of bone fracture. A population-based, nested case-control study was conducted in Lombardia, Northern Italy. The 78,294 women aged 45-75 years who received at least one HRT prescription during 1998-2000 were followed until 2005. Cases were women who experienced bone fracture during follow-up. Up to six controls were randomly selected for each case from the cohort after matching for age and date of cohort entry. The odds ratio of fracture associated with the use of HRT was estimated by conditional logistic regression. One thousand one hundred and seventy-four cases and 6760 controls were included. Compared with women who took HRT for less than 2 months, those who were treated for more than 20 months had an odds ratio (OR) of 0.80 (95% confidence interval 0.65, 0.99). This risk reduction was still significant among current HRT users (OR 0.71, 95% CI 0.55, 0.90) and in women who began therapy at the age of 55-65 years (OR 0.63, 95% CI 0.42, 0.94) or 65-75 years (OR 0.56, 95% CI 0.32, 0.99). There was no statistical evidence of a protective effect for women who had stopped treatment more than 6 months previously or those who began HRT at the age of 45-55 years. HRT should be continued for long periods to achieve an optimal protection from fracture. The fracture reducing potential of HRT seems to disappear after a few months without treatment and might mainly act in women who begin therapy at older age.

Melanome Therapy with Rhenium Cyclized Alpha Melanocyte Stimulating Hormone Peptide Analogs. Final report

Malignant melanoma is the 6th most commonly diagnosed cancer with increasing incidence in the United States. It is estimated that 54,200 cases of malignant melanoma will be newly diagnosed and 7,600 cases of death will occur in the United States in the year 2003 (1). At the present time, more than 1.3% of Americans will develop malignant melanoma during their lifetime (2). The average survival for patients with metastatic melanoma is about 6-9 months (3). Moreover, metastatic melanoma deposits are resistant to conventional chemotherapy and external beam radiation therapy (3). Systematic chemotherapy is the primary therapeutic approach to treat patients with metastatic melanoma. Dacarbazine is the only single chemotherapy agent approved by FDA for metastatic melanoma treatment (5). However, the response rate to Dacarbazine is only approximately 20% (6). Therefore, there is a great need to develop novel treatment approaches for metastatic melanoma. The global goal of this research program is the rational design, characterization and validation of melanoma imaging and therapeutic radiopharmaceuticals. Significant progress has been made in the design and characterization of metal-cyclized radiolabeled alpha-melanocyte stimulating hormone peptides. Therapy studies with 188 Re-CCMSH demonstrated the therapeutic efficacy of the receptor-targeted treatment in murine and human melanoma bearing mice (previous progress report). Dosimetry calculations, based on biodistribution data, indicated that a significant dose was delivered to the tumor. However, 188 Re is a very energetic beta-particle emitter. The longer-range beta-particles theoretically would be better for larger tumors. In the treatment of melanoma, the larger primary tumor is usually surgically removed leaving metastatic disease as the focus of targeted radiotherapy. Isotopes with lower beta-energies and/or shorter particle lengths should be better suited for targeting metastases. The 177 Lu-DOTA-Re(Arg11)CCMSH and

Rheumatoid arthritis (RA) is a chronic inflammatory disease that damages the synovial joints, and patients with it are often anorexic and cachectic with high morbidity and mortality. Biological therapy with anti-tumor necrosis factor (TNF)-α has been proven effective as a treatment for RA. However, the long-term effects of anti-TNF-α therapy on body weight, appetite, plasma gut hormones and leptin have not been investigated. Twenty RA patients received subcutaneous injections of etanercept, a chimeric protein of human IgG1 Fc and TNF receptor p75, twice weekly for 12 consecutive months. Sequential changes in body weight, body fat, appetite rating, lipid profiles, gut hormones and leptin were measured at baseline and at 3 and 12 months after treatment. Ten RA patients who received non-biological disease modifying anti-rheumatic drugs were enrolled as the controls and were appraised at baseline and at 12 months after treatment (a nonrandomized study). Significant weight gain, hyperuricemia, decreased fasting plasma glucose-dependent insulinotropic polypeptide (GIP) levels, and loss of post-oral glucose suppression of plasma leptin concentration were found in the patients after the 12-month course of etanercept therapy, but not in the controls. A transient decrease in fasting plasma acyl ghrelin occurred at 3 months during etanercept treatment. Appetite score and serum lipid profiles did not change in either group. Long-term therapy with anti-TNF-α is promising in ameliorating body mass decrease in patients with active RA. Plasma levels of ghrelin, GIP and leptin may play significant roles in maintaining energy homeostasis in the anti-inflammatory responses during RA remission.

Full Text Available BackgroundWe examined the change in the levels of incretin hormone and effects of glucose-dependent insulinotropic polypeptide (GIP and glucagon-like peptide 1 (GLP-1 on insulin secretion in women with previous gestational diabetes (pGDM.MethodsA 75-g oral glucose tolerance test (OGTT was conducted on 34 women with pGDM. In addition, 11 women with normal glucose tolerance, matched for age, height and weight, were also tested. The insulin, GIP, GLP-1, and glucagon concentrations were measured, and their anthropometric and biochemical markers were also measured.ResultsAmong 34 women with pGDM, 18 had normal glucose tolerance, 13 had impaired glucose tolerance (IGT and 1 had diabetes. No significant differences were found in GLP-1 concentration between the pGDM and control group. However, a significantly high level of glucagon was present in the pGDM group at 30 minutes into the OGTT. The GIP concentration was elevated at 30 minutes and 60 minutes in the pGDM group. With the exception of the 30-minute timepoint, women with IGT had significantly high blood glucose from 0 to 120 minutes. However, there was no significant difference in insulin or GLP-1 concentration. The GIP level was significantly high from 0 to 90 minutes in patients diagnosed with IGT.ConclusionGLP-1 secretion does not differ between pGDM patients and normal women. GIP was elevated, but that does not seem to induce in increase in insulin secretion. Therefore, we conclude that other factors such as heredity and environment play important roles in the development of type 2 diabetes.

Endogenous hormones in postmenopausal females with breast cancer--before and after treatment.

Breast cancer is usually present for many years (as long as 5-10 years) before it can be clinically diagnosed (theory of the 'dormant malignant cell'). This implies that breast cancer cells, during their subclinical period, are likely to have been exposed for a considerable time to endogenous sex hormones and endogenous hormonal milieu predicts the chances of breast cancer in females. So, we planned this study to evaluate the role of endogenous hormones in postmenopausal females excluding the patients on hormone replacement therapy as the relationship between breast cancer and hormone replacement therapy is well known. Hormone therapy is known to affect these hormone levels but whether treatment of breast cancer per se also decreases the hormone levels is not known. We planned the present study to determine hormone levels in patients before and after 4 months of treatment (chemotherapy/surgery and radiotherapy). Circulating hormone levels were measured using a chemiluminescence method. Their results were compared with a group of 25 age matched healthy controls. We found that serum prolactin, testosterone and estrogen levels were very significantly higher in patients before treatment (Group I) as compared to controls (Group III). Serum prolactin and serum estrogen levels were significantly higher and serum testosterone was very significantly higher in patients before treatment (Group I) when compared after 4 months of treatment (Group II). Only serum estrogen levels were significantly high in patients after treatment (Group II) as compared to controls (Group III). Serum progesterone levels showed no significant difference to any of the groups. We concluded that postmenopausal females with breast cancer have abnormalities in hormone levels. These abnormalities may be considered in the pathogenesis of the disease and should be taken into account in the treatment of patients of breast cancer. It might also be helpful to delay the onset of cancer by normalizing the

BACKGROUND AND AIMS: The interaction between cortisol and growth hormone (GH)-levels may significantly influence GH-responses to a stimulation test. In order to systematically analyse the interaction in a paired design, it is necessary to use a test, which has been proven safe and reliable...... such as the pyridostigmine-growth-hormone-releasing-hormone (PD-GHRH) test. Three groups of subjects with a different GH-secretory capacity were included. STUDY A: Eight healthy adults were tested seven times, once with placebo throughout the examination and six times with the PD-GHRH test following no glucocorticoid......-responses to a PD-GHRH test were reduced in all individuals during acute stress-appropriate cortisol levels and the percentage reduction in GH-levels was independent of the GH-secretory capacity. Clinically, we found that peak GH-responses were not significantly affected by a short break in conventional HC therapy...

Full Text Available With increases life expectancy, the incidence of undesirable manifestations of menopause has increased as well. The effects of lost ovarian function include progressive decrease in estradiol secretion, trophic changes in the breast, vasomotor symptoms, anxiety, depression, and sleep disorders. Insomnia, which has physiological consequences and can result in a loss of quality of life, is prevalent in women after menopause. Hormone therapy has been widely used to reduce menopausal symptoms, but its use in recent years has been questioned because of the reported risks of cardiovascular events and increased incidence of tumors. This controversy has generated significant interest in non-hormonal treatments among both physicians and patients. Our previous research has shown a positive effect of massage therapy on menopausal symptoms. We explored the hypothesis that massage therapy would produce beneficial effects in postmenopausal women through inflammatory and immunological changes. Recent results from self-report questionnaires have shown improvements in sleep pattern and quality of life following massage therapy. These findings demonstrate the effectiveness of massage therapy for the treatment of postmenopausal symptoms, particularly insomnia, and indicate that it is a promising line of research.

Full Text Available Background: The role of breast cancer treatments in reducing recurrence and death has been established. However, the treatments side effects greatly impact on quality of life and little is known about the non-adherence rates. The purpose of this study was to determine the non-adherence rates to surgery, chemotherapy, radiotherapy and hormonal therapy, and factors that affect it in public hospitals in Malaysia. Methods: A multicentre cross-sectional study was conducted in six public hospitals involving all newly diagnosed breast cancer patients in 2012. Data were collected through medical record reviews and interview by using structured questionnaire. Non-adherence was categorized as any breast cancer patients refusing or discontinuing any treatment due to non-medical reasons. Univariable logistic regression and multiple logistic regressions were used for analysis. Results: A total of 340 breast cancer patients were included in the study. The proportion for non-adherence to surgery, chemotherapy, radiotherapy and hormonal therapy were 14%, 30.1%, 33.3% and 36.3% respectively. Factors associated with non-adherence to surgery were localities involving Kuala Lumpur (2 (OR: 3.41, Johor (OR: 8.38 and Kelantan (OR: 6.32, and those required mastectomy (OR: 5.66. No factors were found to be associated with non-adherence to chemotherapy, radiotherapy and hormonal therapy. These three treatment modalities were then combined as oncology therapy and the only independent factor associated with non-adherence to oncology therapy was Perak locality (OR: 1.42. Conclusion: Non-adherence to breast cancer treatments was high among breast cancer patients at public hospitals in Malaysia. Factors influencing non-adherence were locations and mastectomy implicating of socio-culture, body image issues, psychological disturbance and treatment navigation.

Recombinant human growth hormone (rhGH) is being used to promote linear growth in short children with Noonan syndrome. However, its efficacy is still controversial. To systematically determine the impact of rhGH therapy on adult height in children with Noonan syndrome. We searched the Cochrane Central Register of Controlled Trials, ISI Web of Science, MEDLINE, and the bibliographic references from all retrieved articles published until April 2014. Studies reporting adult/near-adult height in children with Noonan syndrome treated with rhGH or reporting at least a 3-year follow-up were analysed. Quality and strength of recommendation were assessed according to the Endocrine Society criteria. No controlled trials reporting adult height were available. Five studies were identified reporting adult height or near adult height. Data comparison showed inter-individual variability in the response to rhGH, mean height gain standard deviation score ranging between 0.6 and 1.4 according to national standards, and between 0.6 and 2 according to Noonan standards. Significant biases affected all the studies. High-quality controlled trials on the impact of rhGH therapy on adult height are lacking, and the robustness of available data is not sufficient to recommend such therapy in children with Noonan syndrome. © 2015 S.

Climacteric medicine has been in focus during the last 2 decades, and an intensive debate has been ongoing regarding the positive and negative aspects of postmenopausal hormone therapy (HT). Recent randomised controlled studies have been unable to confirm data from observational studies of primary...... or secondary preventive effects of HT on coronary heart disease, and other studies have indicated an increased risk of breast cancer, stroke and venous thromboembolism among HT users. In 2001, we reported on knowledge, attitudes, management strategies and use of HT among Scandinavian gynaecologists. The aim...... of the present study was to re-assess the same parameters concerning HT among Scandinavian gynaecologists in 2002-2003, and compare the results with the data collected in 1995-1997....

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.

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).

Full Text Available Both pulsatile gonadotropin-releasing hormone (GnRH infusion and combined gonadotropin therapy (human chorionic gonadotropin and human menopausal gonadotropin [HCG/HMG] are effective to induce spermatogenesis in male patients with congenital hypogonadotropic hypogonadism (CHH. However, evidence is lacking as to which treatment strategy is better. This retrospective cohort study included 202 patients with CHH: twenty had received pulsatile GnRH and 182 had received HCG/HMG. Patients had received therapy for at least 12 months. The total follow-up time was 15.6 ± 5.0 months (range: 12-27 months for the GnRH group and 28.7 ± 13.0 months (range: 12-66 months for the HCG/HMG group. The median time to first sperm appearance was 6 months (95% confidence interval [CI]: 1.6-10.4 in the GnRH group versus 18 months (95% CI: 16.4-20.0 in the HCG/HMG group (P 1 × 10 6 ml−1 was 43.7% ± 20.4% (16 samples in the GnRH group versus 43.2% ± 18.1% (153 samples in the HCG/HMG group (P = 0.921. Notably, during follow-up, the GnRH group had lower serum testosterone levels than the HCG/HMG group (8.3 ± 4.6 vs 16.2 ± 8.2 nmol l−1 , P < 0.001. Our study found that pulsatile GnRH therapy was associated with earlier spermatogenesis and larger testicular size compared to combined gonadotropin therapy. Additional prospective randomized studies would be required to confirm these findings.

Ischemic stroke sets in motion a dialogue between the central nervous and the immune systems that includes the sympathetic/adrenal system. We investigated the course of immune cells and adrenocortical and adrenomedullary effectors in a cohort of 51 patients with acute stroke receiving reperfusion therapy (intravenous alteplase or mechanical thrombectomy) and its correlation with stroke outcomes and infarct growth. Cortisol increased rapidly and fleetingly after stroke, but 39% of patients who had larger infarctions on admission showed a positive delta cortisol at day 1. It was associated with enhanced infarct growth (p = 0.002) and poor outcome [OR (95% CI) 5.30 (1.30-21.69)], and correlated with less lymphocytes and T cells at follow up. Likewise, fewer circulating lymphocytes, T cells, and Tregs were associated with infarct growth. By contrast, metanephrines did not increase at clinical onset, and decreased over time. Higher levels of NMN correlated with more Treg and B cells. Eventually, complete reperfusion at the end of therapy headed the identification of more circulating Tregs at day 1. Then activation of cortical or medullar compartments of the adrenal gland result in specific signatures on leukocyte subpopulations. Manipulation of the adrenal gland hormone levels warrants further investigation. Copyright © 2018. Published by Elsevier Inc.

Aim: Despite extensive use of {sup 131}I therapy for Graves' hyperthyroidism the treatment regimen with {sup 131}I and antithyroid drugs remain under discussion. In our prospective clinical study we followed acute thyroid hormone changes after {sup 131}I in patients not pretreated with methimazole (MMI) and in patients with different MMI pretreatment regimes. Patients, methods: 187 patients were treated with fixed activity of 550 or 740 MBq of {sup 131}I. First group (71 patients) received {sup 131}I alone. In the second group (57 patients) MMI was stopped seven days before {sup 131}I. The third group (59 patients) received MMI until {sup 131}I application. Initial free triodothyronin and free thyroxin were measured in the second group 7 and 2 days before {sup 131}I therapy and in all three groups on the day of {sup 131}I application as well as 2, 5, 12, and 30 days afterwards. Absorbed dose was measured in each patient. Results: In the non-pretreated group {sup 131}I application was followed by a significant decrease of fT{sub 4} in 5 days and of fT{sub 3} in 2 days, higher reduction was detected in patients with higher baseline values. In MMI pretreated patients significant but clinically irrelevant increase of both thyroid hormones was detected with maximum value 7 days after discontinuation in the second group and 5 days after discontinuation in the third group. Additionally, in patients of the third group absorbed dose of {sup 131}I was significantly lower relative to other two groups. We found no correlation between absorbed dose of {sup 131}I and thyroid hormone changes. Conclusion: Our study demonstrates that {sup 131}I application alone does not result in exacerbation of hyperthyroidism and therefore it may be considered as safe. Additionally, MMI withdrawal causes significant but clinically irrelevant elevation of thyroid hormones. (orig.)

Radiation therapy for prostate cancer

In Japan, where the mortality rate of prostate cancer is lower than in Western countries, radical prostatectomy or hormonal therapy has been applied more frequently than radiation therapy. However, the number of patients with prostate cancer has been increasing recently and the importance of radiation therapy has rapidly been recognized. Although there have been no randomized trials, results from several institutions in Western countries suggest that similar results of cancer control are achieved with either radiation therapy or radical prostatectomy. For higher-risk cases, conformal high-dose therapy or adjuvant hormonal therapy is more appropriate. In this article, the results of radiation therapy for prostate cancer were reviewed, with a view to the appropriate choice of therapy in Japan. (author)

Pre-treatment growth and IGF-I deficiency as main predictors of response to growth hormone therapy in neural models

Directory of Open Access Journals (Sweden)

Full Text Available Mathematical models have been applied in prediction of growth hormone treatment effectiveness in children since the end of 1990s. Usually they were multiple linear regression models; however, there are also examples derived by empirical non-linear methods. Proposed solution consists in application of machine learning technique – artificial neural networks – to analyse this problem. This new methodology, contrary to previous ones, allows detection of both linear and non-linear dependencies without assuming their character a priori. The aims of this work included: development of models predicting separately growth during 1st year of treatment and final height as well as identification of important predictors and in-depth analysis of their influence on treatment’s effectiveness. The models were derived on the basis of clinical data of 272 patients treated for at least 1 year, 133 of whom have already attained final height. Starting from models containing 17 and 20 potential predictors, respectively for 1st year and final height model, we were able to reduce their number to 9 and 10. Basing on the final models, IGF-I concentration and earlier growth were indicated as belonging to most important predictors of response to GH therapy, while results of GH secretion tests were automatically excluded as insignificant. Moreover, majority of the dependencies were observed to be non-linear, thus using neural networks seems to be reasonable approach despite it being more complex than previously applied methods.

Several studies have been conducted to estimate persistence to hormonal therapy among women with breast cancer (BC). Most studies focus on first treatment discontinuation. Patients, however, can have numerous periods of treatment discontinuation or treatment exposure. Our objective is to estimate persistence to tamoxifen in patients with BC while accounting for temporary treatment discontinuations and this by using multi-state (MS) models. A cohort of 10,806 women with BC having received at least one prescription of tamoxifen between 1998 and 2008 was constituted from the UK General Practice Research Database. We fitted a semi-Markov model with three states to estimate the probability of being off treatment over a 5-year period while accounting for temporary treatment discontinuations (transition between on treatment and off treatment) and competing risks (recurrence of BC or death). Non-persistence, as estimated from the MS model, ranged from 12.1% (95% confidence interval [95%CI]: 9.2-15.1) at 1 year to 14.9% (95%CI: 11.7-18.1) at 5 years. Estimations of non-persistence based on the Kaplan-Meier model were higher, i.e., 29.3% (95%CI: 28.1-30.6) at 5 years, as well as those obtained from a competing risk model, i.e., 24.0% (95%CI: 22.9-25.1). Most temporary discontinuations (94.7%) lasted less than 6 months. Temporary treatment discontinuations are frequent and should be accounted for when measuring adherence to treatment. MS models can provide a useful framework for this sort of analysis insofar as they help describe patients' complex behavior. This may help tailor interventions that improve persistence to hormonal therapy among women with BC. Copyright © 2014 John Wiley & Sons, Ltd.

Parental height is the most important identifiable factor influencing final height (FH) of children with growth hormone (GH) deficiency (GHD), treated with GH. Assessment of FH of patients with GHD--classified into familial short stature (FSS) and non-familial short stature (non-FSS) according to parentally adjusted deficit of height. The analysis comprised 101 patients (76 boys) with childhood-onset GHD. Final height was compared with patients' height before GH therapy, predicted adult height (PAH) and target height (TH). Both GH peak in stimulating tests and height standard deviation score (SDS) before the therapy were significantly lower in non-FSS than in FSS. Target height was significantly lower in FSS than in non-FSS. Parentally-adjusted deficit of height was significantly more profound in non-FSS than in FSS. The prognosis of adult height was very similar in both groups of patients, being significantly worse in non-FSS than in FSS while corrected by TH. The absolute FH was similar in FSS and non-FSS, being, however, significantly lower in non-FSS than in FSS while corrected by TH. Improvement of height was significantly better in non-FSS than in FSS. In both groups, FH SDS was significantly better than height SDS before the therapy (H0SDS). In FSS group, PAH was similar to TH, moreover, FH corresponded to both PAH and TH. In non-FSS group FH was significantly higher than PAH, but both FH and PAH were significantly lower than TH. 1) Growth hormone therapy was more effective in the patients with non-FSS than in those with FSS. 2) Parentally-adjusted deficit of height is an important prognostic factor of GH therapy effectiveness.

A survey based on a postal questionnaire sent to a random sample of Danish women aged 40-59 yr living on the island of Fünen (n = 401, response rate = 79%) revealed that the overall prevalence of the use of hormone replacement therapy (HRT) was 16%, the highest rate being in the 50-54 age group (21......%). Among post-menopausal women the rate was 21% and it was highest of all (37%) in those who had undergone an artificial menopause. The median age at the start of treatment was 44.3 yr among the artificial menopause and 48.9 yr among the natural menopause subjects. About half of the women were treated...... with natural oestrogen alone and over a third with cyclic natural oestrogen in combination with progestogens. Almost one-third of the women had consulted their doctor about climacteric complaints and two-thirds of these were current or past users of HRT. The women had ambiguous feelings towards HRT...

Hormone resistance in two MCF-7 breast cancer cell lines is associated with reduced mTOR signaling, decreased glycolysis and increased sensitivity to cytotoxic drugs

Directory of Open Access Journals (Sweden)

Euphemia Yee Leung

2014-09-01

Full Text Available The mTOR pathway is a key regulator of multiple cellular signaling pathways and is a potential target for therapy. We have previously developed two hormone-resistant sub-lines of the MCF-7 human breast cancer line, designated TamC3 and TamR3, which were characterized by reduced mTOR signaling, reduced cell volume and resistance to mTOR inhibition. Here we show that these lines exhibit increased sensitivity to carboplatin, oxaliplatin, 5-fluorouracil, camptothecin, doxorubicin, paclitaxel, docetaxel and hydrogen peroxide. The mechanisms underlying these changes have not yet been characterized but may include a shift from glycolysis to mitochondrial respiration. If this phenotype is found in clinical hormone-resistant breast cancers, conventional cytotoxic therapy may be a preferred option for treatment.

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.

Long-Term Treatment Sequelae After External Beam Irradiation With or Without Hormonal Manipulation for Adenocarcinoma of the Prostate: Analysis of Radiation Therapy Oncology Group Studies 85-31, 86-10, and 92-02

Purpose: Late gastrointestinal (GI) and genitourinary (GU) morbidity from external beam irradiation used to treat adenocarcinoma of the prostate continue to be a concern of physicians and patients alike. In addition, for locally advanced/high-risk cancer, the appropriate use of hormonal manipulation in addition to radiation therapy (RT) may increase toxicity. We analyzed three large Radiation Therapy Oncology Group (RTOG) studies (85-31, 86-10, and 92-02) to try to address these issues. Methods and Materials: A total of 2,922 patients were accrued with a median follow-up of 10.3 years for surviving patients. The RTOG scoring scheme was used to assess GI, GU, and other toxicities. Toxicity reported was Grade 3 or higher late toxicity. Patient toxicity level was assessed by study and by treatment type combining RT only vs. RT + short-course hormone therapy (STH) vs. RT + long-term hormone therapy (LTH). Results: Multivariate analysis reveals that age >70 was statistically significantly associated with a decrease in late any Grade 3+ toxicity (hazard ratio [HR] = 0.78, p = 0.0476) adjusted for treatment type. Comparing treatment type, patients treated with RT+STH had a statistically significant lower probability of Grade 3+ GI, GU, and other toxicity compared with RT alone (p = .00006; p = 0.0037; p = 0.0127, respectively). Patients treated with RT+LTH had a statistically significant lower probability of Grade 3+ GU toxicity compared with RT alone (p = 0.023). Conclusions: These data show that external beam radiation therapy remains a safe option for locally advanced/high-risk prostate cancer, and the use of hormonal manipulation does appear to be protective for GU and GI toxicity depending upon length of treatment

The efficacy and safety of growth hormone therapy in children with noonan syndrome: a review of the evidence.

Science.gov (United States)

Noonan, Jacqueline A; Kappelgaard, Anne-Marie

2015-01-01

Noonan syndrome is a genetic disorder associated with short stature. We reviewed 15 studies in which growth hormone (GH) therapy was used in children with Noonan syndrome. Data show consistent increases in mean height standard deviation score (SDS), with first-year changes of up to 1.26 SDS. Among studies reporting adult or near-adult height, GH therapy over 5-7 years resulted in adult height SDS from -0.6 to -2.1, with up to 60% of subjects in some studies achieving adult height within 1 SDS of mid-parental height. GH treatment results in an acceleration of bone age, likely reflecting normalization from the retarded bone age common in Noonan syndrome patients at the start of therapy. BMI is not affected by GH treatment, but favorable changes in fat mass and body composition are achievable. Longer-term studies and observational studies suggest a waning of the effect of GH therapy over time, as is seen in other GH-treated conditions, and early initiation of therapy and prepubertal status are important predictors of response. GH treatment does not appear to be associated with adverse cardiac or metabolic effects, and data on malignancy during GH treatment give no cause for concern, although they are limited. © 2014 S.

Headache And Hormones

Directory of Open Access Journals (Sweden)

Shukla Rakesh

2002-01-01

Full Text Available There are many reasons to suggest a link between headache and hormones. Migraine is three times common in women as compared to men after puberty, cyclic as well as non-cyclic fluctuations in sex hormone levels during the entire reproductive life span of a women are associated with changes in frequency or severity of migraine attack, abnormalities in the hypothalamus and pineal gland have been observed in cluster headache, oestrogens are useful in the treatment of menstrual migraine and the use of melatonin has been reported in various types of primary headaches. Headache associated with various endocrinological disorders may help us in a better understanding of the nociceptive mechanisms involved in headache disorders. Prospective studies using headache diaries to record the attacks of headache and menstrual cycle have clarified some of the myths associated with menstrual migraine. Although no change in the absolute levels of sex hormones have been reported, oestrogen withdrawal is the most likely trigger of the attacks. Prostaglandins, melatonin, opioid and serotonergic mechanisms may also have a role in the pathogenesis of menstrual migraine. Guidelines have been published by the IHS recently regarding the use of oral contraceptives by women with migraine and the risk of ischaemic strokes in migraineurs on hormone replacement therapy. The present review includes menstrual migraine, pregnancy and migraine, oral contraceptives and migraine, menopause and migraine as well as the hormonal changes in chronic migraine.

To examine the relationship between pituitary anatomy and the degree of hormonal dysfunction. This study involved a retrospective review of MRI findings in all children diagnosed with congenital growth hormone deficiency from 1988 to 2010 at a tertiary-level pediatric hospital. Of the 52 MRIs reviewed in 52 children, 26 children had normal pituitary anatomy and 26 had one or more elements of the classic triad. Fourteen of fifteen children with multiple pituitary hormone deficiencies had structural anomalies on MRI. Twelve of 37 children with isolated growth hormone deficiency had an abnormal MRI. Children with multiple pituitary hormone deficiencies were more likely to have the classic triad than children with isolated growth hormone deficiency. A normal MRI was the most common finding in children with isolated growth hormone deficiency. (orig.)

Recombinant human thyroid-stimulating hormone (rhTSH)-based protocol is a promising recent development in the management of differentiated thyroid carcinoma (DTC). The objectives of this prospective study were: (1) to assess the feasibility and efficacy of the rhTSH primed 131 I therapy protocol in patients with DTC with distant metastatic disease, (2) to perform lesional dosimetry in this group of patients compared to the traditional protocol, (3) to document the practical advantages (patient symptoms and hospital stay) of the rhTSH protocol compared to the traditional thyroid hormone withdrawal protocol, (4) to document and record any adverse effect of this strategy, (5) to compare the renal function parameters, and (6) to compare the serum TSH values achieved in either of the protocols in this group of patients. The study included 37 patients with metastatic DTC having lung or skeletal metastases or both. A comparison of lesional radiation absorbed dose, hospital stay, renal function tests, and symptom profile was undertaken between the traditional thyroid hormone withdrawal protocol and rhTSH-based therapy protocol. Dosimetric calculations of metastatic lesions were performed using lesion uptake and survey meter readings for calculation of effective half-life. Non-contrast-enhanced CT was used for assessment of tumor volume. Quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QOL forms. A comparison of pretreatment withdrawal thyroglobulin (TG) was done with the withdrawal TG level 3 months after treatment. The mean effective half-life of 131 I in metastatic lesions was less during the rhTSH protocol (29.49 h) compared to the thyroid hormone withdrawal protocol (35.48 h), but the difference was not statistically significant (p = 0.056). The mean 24-h % uptake of the lesions during the traditional protocol (4.84 %) was slightly higher than the 24-h % uptake during the rhTSH protocol (3.56 %), but the

Purpose: Females incidentally irradiated to the hypothalamic-pituitary axis (H/P-A) during radiation therapy (RT) for brain tumors may become oligoamenorrheic. We previously demonstrated that these women are hypoestrogenemic but frequently have near normal or only moderately decreased basal luteinizing hormone (LH) levels and maintain appropriate peak pituitary responses to exogenous gonadotropin releasing hormone (GnRH). We postulated that hypothalamic injury resulting in abnormal LH pulsatility could explain this complex of findings. This investigation intended to characterize this hypothalamic injury and test two potentially corrective pharmacologic interventions. Catecholamines (specifically dopamine) and opiates are known to suppress pituitary LH release through inhibition of the pituitary gonadotropes or of the GnRH neuronal terminals in the hypothalamus. Radiation-induced dysfunction of the catecholaminergic or opiate control mechanisms might translate into an increase in dopamine or opiate release or receptor responsiveness, which in turn would inhibit pulsatile gonadotropin secretion, leading to reduced LH pulsatility and to gonadal dysfunction. We therefore determined the pattern of LH release in normal controls and in patients, at baseline as well as after administration of the dopamine receptor antagonist metoclopramide (MCP), and the opiate-receptor antagonist naloxone (NAL). Methods: Patient eligibility criteria included RT to the H/P-A for a non-H/P-A CNS tumor, usually astrocytoma, with subsequent hypoestrogenemia and oligo-amenorrhea. Patients and normal volunteers were studied first under control conditions and then using MCP and NAL in a randomized cross-over manner at monthly intervals. Serum samples for LH determination were taken every 10 minutes for 12 hours during an overnight hospital stay. MCP (10 mg) was administered as an IV bolus every 4.5 hours, and NAL was administered as a continuous infusion (1.6 mg/hour). The following morning each

Sex and Hormonal influences on Seizures and Epilepsy

Epilepsy is the third most common chronic neurological disorder. Clinical and experimental evidence supports the role of sex and influence of sex hormones on seizures and epilepsy as well as alterations of the endocrine system and levels of sex hormones by epileptiform activity. Conversely, seizures are sensitive to changes in sex hormone levels, which in turn may affect the seizure-induced neuronal damage. The effects of reproductive hormones on neuronal excitability and seizure-induced damage are complex to contradictory and depend on different mechanisms, which have to be accounted for in data interpretation. Both estradiol and progesterone/allopregnanolone may have beneficial effects for patients with epilepsy. Individualized hormonal therapy should be considered as adjunctive treatment in patients with epilepsy to improve seizure control as well as quality of life. PMID:22504305

Full Text Available This report presents a case of a 12-year-old girl with maxillary deficiency, mandibular prognathism, and facial asymmetry, undergoing growth hormone (GH therapy due to idiopathic short stature. Children of short stature with or without GH deficiency have a deviating craniofacial morphology with overall smaller dimensions; facial retrognathism, especially mandibular retrognathism; and increased facial convexity. However, a complete opposite craniofacial pattern was presented in our case of a skeletal Class III girl with idiopathic short stature. The orthodontic treatment goal was to inhibit or change the direction of mandibular growth and stimulate the maxillary growth of the girl during a course of GH therapy. Maxillary protraction and mandibular retraction were achieved using occipitomental anchorage (OMA orthopedic appliance in the first stage of treatment. In the second stage, the patient was treated with a fixed orthodontic appliance using a modified multiple-loop edgewise archwire technique of asymmetric mechanics and an active retainer of vertical chin-cup. The treatment led to an acceptable facial profile and obvious facial asymmetry improvement. Class I dental occlusion and coincident dental midline were also achieved. A 3½-year follow-up of the girl at age 18 showed a stable result of the orthodontic and dentofacial orthopedic treatment. Our case shows that the OMA orthopedic appliance of maxillary protraction combined with mandibular retraction is effective for correcting skeletal Class III malocclusion with midface deficiency and mandibular prognathism in growing children with idiopathic short stature undergoing GH therapy.

Gynecomastia is an abnormal increase in the volume of the male breast that is generally considered to be due to an increased estrogen/androgen ratio. Pathological causes of gynecomastia include organic diseases and therapy, such as the administration of estrogens and antiandrogens, which alter the ratio of circulating hormones. Hormone therapy for prostate cancer is generally well tolerated but often accompanied by the occurrence of gynecomastia and breast pain or tenderness. The increased use of antiandrogens as monotherapy is leading to an increase in the number of patients affected by gynecomastia. Treatments are available to alleviate or prevent the development of gynecomastia, including medical treatment with antiestrogens and aromatase inhibitors. Alternatively, mastectomy with excision of the gland, liposuction or an association of the two techniques have proved to be effective. Radiation therapy may provide effective relief from the breast pain associated with gynecomastia. In this paper we show the good results of mastectomy performed with a lower semicircular periareolar incision in men suffering from gynecomastia due to antiandrogen therapy for inoperable prostate cancer. In addition, we present a review of the various techniques used for the treatment of gynecomastia. During the period from September 1998 to May 2001, 10 patients receiving hormone treatment for metastatic or inoperable prostatic cancer were selected for the study if they had breast pain and bilateral gynecomastia. Five of these patients had been offered prophylactic radiotherapy before treatment but refused, while the remaining five patients had refused radiotherapy after hormone treatment. These patients were therefore given the option of surgical treatment. Before surgery all patients underwent clinical and ultrasound examination of the breast. All surgical samples were examined histopathologically. During follow-up clinical examinations were carried out one week, one month, six

Full Text Available Hormone replacement therapy (HRT reduces cardiovascular risks, although the initiation of therapy may be associated with transient adverse ischemic and thrombotic events. Antibodies against heat shock protein (Hsp and oxidized low density lipoprotein (LDL have been found in atherosclerotic lesions and plasma of patients with coronary artery disease and may play an important role in the pathogenesis of atherosclerosis. The aim of the present study was to assess the effects of HRT on the immune response by measuring plasma levels of antibodies against Hsp 65 and LDL with a low and high degree of copper-mediated oxidative modification of 20 postmenopausal women before and 90 days after receiving orally 0.625 mg equine conjugate estrogen plus 2.5 mg medroxyprogesterone acetate per day. HRT significantly increased antibodies against Hsp 65 (0.316 ± 0.03 vs 0.558 ± 0.11 and against LDL with a low degree of oxidative modification (0.100 ± 0.01 vs 0.217 ± 0.02 (P<0.05 and P<0.001, respectively, ANOVA. The hormone-mediated immune response may trigger an inflammatory response within the vessel wall and potentially increase plaque burden. Whether or not this immune response is temporary or sustained and deleterious requires further investigation.

Twenty-four cases of pituitary adenoma, 13 males and 11 females with the age ranging from 11 to 65 years, received radiation therapy(RT) on the pituitary area with 6MV linear accelerator during past 25 months at the Division of Radiation Therapy, Kangnam St. Mary Hospital, Catholic Medical College. Of 24 case of RT, 20 were postoperative and 4 primary. To evaluate the effect of RT, we analyzed the alteration of the endocrinological tests, neurologic abnormalities, major clinical symptoms, endocrinological changes and improvement in visual problems after RT. The results were as follows ; 1. Major clinical symptoms were headache, visual defects, diabetes insipidus, hypogonadisms and general weakness in decreasing order of frequency. 2. All but the one with Nelson syndrome showed abnormal neuroradiologic changes in the sella turcica with an invasive tumor mass around supra and para-sellar area. 3. Endocrinological classifications of the patient were 11 prolactinoma, 4 growth hormonesecreting tumors, 3 ACTH-secreting tumors consisting of one Cushing disease and two Nelson syndrome, and 6 nonfunctioning tumors. 4. Eleven of 14 patients, visual problems were improved after treatment but remaining 3 were unchanged. 5. Seven of 11 prolactinomas returned to normal hormonal level after postoperative and primary RT and 3 patients are being treated with bromocriptine (BMCP) but on lost case. 6. Two of 4 growth hormone-secreting tumor returned to normal level after RT but the remaining 2 are being treated with BMCP, as well

A case in which radiotherapy was requested for bone metastases from prostate carcinoma after hormonal and radiation therapy and diagnosed as insufficiency fracture of the sacrum on bone scan was reported. A 78-year-old man underwent endocrine therapy with luteinizing hormone releasing hormone agonists and radical radiotherapy toward pelvis for prostate cancer. The onset of buttock pain started from the nine-month after the beginning of radiotherapy, and was diagnosed as sacrum metastasis by MRI, and radiotherapy was requested again for pain control. However, on bone scan, butterfly-like changed accumulation was noted, therefore sacrum insufficiency fracture was suspected. Addition of CT inspection and reconfirmation of MRI were performed, and bone metastases became negative, and serial observation was performed of the painkilling effect after that. No tumor marker rise was seen after five months without sigh of new bone metastases and the final diagnosis became insufficient fracture. In order to avoid unnecessary treatment, we think that the view of bone scintigram for diagnosis of sacrum insufficient fracture should be known. (author)

Sex Hormone Receptor Repertoire in Breast Cancer

Directory of Open Access Journals (Sweden)

Gerald M. Higa

2013-01-01

Full Text Available Classification of breast cancer as endocrine sensitive, hormone dependent, or estrogen receptor (ER positive refers singularly to ERα. One of the oldest recognized tumor targets, disruption of ERα-mediated signaling, is believed to be the mechanistic mode of action for all hormonal interventions used in treating this disease. Whereas ERα is widely accepted as the single most important predictive factor (for response to endocrine therapy, the presence of the receptor in tumor cells is also of prognostic value. Even though the clinical relevance of the two other sex hormone receptors, namely, ERβ and the androgen receptor remains unclear, two discordant phenomena observed in hormone-dependent breast cancers could be causally related to ERβ-mediated effects and androgenic actions. Nonetheless, our understanding of regulatory molecules and resistance mechanisms remains incomplete, further compromising our ability to develop novel therapeutic strategies that could improve disease outcomes. This review focuses on the receptor-mediated actions of the sex hormones in breast cancer.

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.

Growth hormone treatment stimulates growth in short children with chronic renal failure. However, the extent to which this therapy increases final adult height is not known. We followed 38 initially prepubertal children with chronic renal failure treated with growth hormone for a mean of 5.3 years until they reached their final adult height. The mean (+/-SD) age at the start of treatment was 10.4+/-2.2 years, the mean bone age was 7.1+/-2.3 years, and the mean height was 3.1+/-1.2 SD below normal. Fifty matched children with chronic renal failure who were not treated with growth hormone served as controls. The children treated with growth hormone had sustained catch-up growth, whereas the control children had progressive growth failure. The mean final height of the growth hormone-treated children was 165 cm for boys and 156 cm for girls. The mean final adult height of the growth hormone-treated children was 1.6+/-1.2 SD below normal, which was 1.4 SD above their standardized height at base line (Pgrowth hormone-treated children, treatment was not associated with a shortening of the pubertal growth spurt. The total height gain was positively associated with the initial target-height deficit and the duration of growth hormone therapy and was negatively associated with the percentage of the observation period spent receiving dialysis treatment. Long-term growth hormone treatment of children with chronic renal failure induces persistent catch-up growth, and the majority of patients achieve normal adult height.

Hormonal protection of spermatogenic stem cells during irradiation

In this thesis it is examined if by hormonal suppression of spermatogenesis the disadvantageous side-effects of radiation therapy on the gonads can be reduced. Therefore a rat model was investigated, where hormonal suppression of spermatogenesis during irradiation was achieved and stem cell survival was measured. Attention was focussed on the stem cell, because this cell is primarily responsible for the late effects of radiation on fertility. Flow cytometrical and histological techniques were used as parameters for measuring stem cell survival. Serum concentrations of FSH, LH and testosterone were measured to evaluate the hormonal suppression. (Auth.)

The pathogenesis of bone necrosis is discussed with special attention and with respect to metabolic, hormonal, and vascular factors. The influence of statics and dynamics of the hip joint bones for the development of aseptic necrosis are discussed. 45 patients with ''idiopathic femoral head necroses'' were observed, including 6 cases of renal osteopathy following renal transplantation and immune suppression therapy, 14 cases of long term corticoid therapy, and 11 cases of liver diseases of different genesis. The femoral head necrosis understood as complication of an osteopathy. In our patients there were 31 males and 14 females - which means higher involvement of males. Plain radiological findings and CT-findings of changes of the femoral heat structure in different stages of the disease are described. Early diagnosis of metabolic and hormonal osteopathies is demanded for a joint keeping therapy of the beginning femoral head necrosis. (orig.) [de

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

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.

Full Text Available Like women, old female rhesus macaques undergo menopause and show many of the same age-associated changes, including perturbed activity/rest cycles and altered circulating levels of many hormones. Previous studies showed that administration of an estrogen agonist increased activity in female monkeys, that hormone therapy (HT increased activity in postmenopausal women and that obesity decreased activity in women. The present study sought to determine if postmenopausal activity and circulating hormone levels also respond to HT when monkeys are fed a high-fat, high-sugar Western style diet (WSD. Old female rhesus macaques were ovo-hysterectomized (OvH to induce surgical menopause and fed a WSD for 2 years. Half of the animals received estradiol-17β (E, beginning immediately after OvH, while the other half received placebo. Animals in both groups showed an increase in body weight and a decrease in overall activity levels. These changes were associated with a rise in both daytime and nocturnal serum leptin concentrations, but there was no change in serum concentrations of either cortisol or dehydroepiandrosterone sulfate (DHEAS. These data suggest that 2 years of HT has little or no effect on locomotor activity or circadian hormone patterns in menopausal macaques fed an obesogenic diet.

Deficiência progressiva dos hormônios adeno-hipofisários após radioterapia em adultos Progressive pituitary hormone deficiency following radiation therapy in adults

Full Text Available A radioterapia é um dos fatores desencadeantes do hipopituitarismo, mesmo quando não direcionada diretamente para o eixo hipotálamo-hipofisário, podendo resultar em redução de hormônios adeno-hipofisários, principalmente por lesão hipotalâmica. A perda da função da hipófise anterior é progressiva e geralmente na seguinte ordem: hormônio do crescimento, gonadotrofinas, adrenocorticotrofina e o hormônio estimulante da tireóide. Vários testes estão disponíveis para a confirmação das deficiências, sendo discutidos, neste artigo, os melhores testes para pacientes submetidos à irradiação. Enfatizamos que o desenvolvimento do hipopituitarismo após a radioterapia é dose e tempo dependente de irradiação, com algumas diferenças entre os eixos hipofisários. Portanto, a conscientização da necessidade de terapia em conjunto de endocrinologistas e oncologistas otimizará o tratamento e a qualidade de vida do paciente.Hypopituitarism can be caused by radiation therapy, even when it is not directly applied on the hypothalamic-pituitary axis, and can lead to anterior pituitary deficiency mainly due to hypothalamic damage. The progressive loss of the anterior pituitary hormones usually occurs in the following order: growth hormone, gonadotropin hormones, adrenocorticotropic hormone and thyroid-stimulating hormone. Although there are several different tests available to confirm anterior pituitary deficiency, this paper will focus on the gold standard tests for patients submitted to radiation therapy. We emphasize that the decline of anterior pituitary function is time- and dose-dependent with some variability among the different axes. Therefore, awareness of the need of a joint management by endocrinologists and oncologists is essential to improve treatment and quality of life of the patients.

Hormonal Changes and Sexual Dysfunction.

2017-11-01

Sexual dysfunction is a common concern for many patients with cancer after treatment. Hormonal changes as a result of cancer-directed therapy can affect both male and female sexual health. This has the potential to significantly impact patients' quality of life, but is underreported and undertreated in the oncology setting. This review discusses commonly reported sexual issues and the role that hormonal changes play in this dysfunction. Although medical and psychosocial intervention strategies exist, there is a clear need for further research to formally develop programming that can assist people whose sexual health has been impacted by cancer treatment.

Objective: To investigate the effects of hormone therapy on brain structure in a randomized, double-blinded, placebo-controlled trial in recently postmenopausal women. Methods: Participants (aged 42–56 years, within 5–36 months past menopause) in the Kronos Early Estrogen Prevention Study were randomized to (1) 0.45 mg/d oral conjugated equine estrogens (CEE), (2) 50 μg/d transdermal 17β-estradiol, or (3) placebo pills and patch for 48 months. Oral progesterone (200 mg/d) was given to active treatment groups for 12 days each month. MRI and cognitive testing were performed in a subset of participants at baseline, and at 18, 36, and 48 months of randomization (n = 95). Changes in whole brain, ventricular, and white matter hyperintensity volumes, and in global cognitive function, were measured. Results: Higher rates of ventricular expansion were observed in both the CEE and the 17β-estradiol groups compared to placebo; however, the difference was significant only in the CEE group (p = 0.01). Rates of ventricular expansion correlated with rates of decrease in brain volume (r = −0.58; p ≤ 0.001) and with rates of increase in white matter hyperintensity volume (r = 0.27; p = 0.01) after adjusting for age. The changes were not different between the CEE and 17β-estradiol groups for any of the MRI measures. The change in global cognitive function was not different across the groups. Conclusions: Ventricular volumes increased to a greater extent in recently menopausal women who received CEE compared to placebo but without changes in cognitive performance. Because the sample size was small and the follow-up limited to 4 years, the findings should be interpreted with caution and need confirmation. Classification of evidence: This study provides Class I evidence that brain ventricular volume increased to a greater extent in recently menopausal women who received oral CEE compared to placebo.

Full Text Available PurposeNoonan syndrome (NS is characterized by short stature, heart anomalies, developmental delays, dysmorphic features, cryptorchidism, and coagulation defects. Several studies reported the short-term effects of recombinant human growth hormone (rhGH treatment on the improvement of height. This study was performed to evaluate the long-term efficacy of rhGH in children with NS in Korea.MethodsThis study included 15 prepubertal NS children who received rhGH subcutaneously at a dose of 50–75 µg/kg/day for 6 days a week for at least >3 years. Preand posttreatment data, such as height, weight, bone age, insulin-like growth factor 1 (IGF-1, and IGF binding protein 3 (IGFBP-3 levels, were collected every 6 months.ResultsChronologic age and bone age at the start of treatment were 7.97±1.81 and 5.09±2.12 years, respectively. Height standard deviation score (SDS was increased from –2.64±0.64 to –1.54±1.24 years after 3 years (P<0.001. Serum IGF-1 SDS levels were elevated from –1.28±1.03 to –0.10±0.94 (P<0.001. Height SDS was more increased in subjects without PTPN11 mutations compared to those with mutations after 3 years (P=0.012. However, the other parameters, including bone age, IGF-1 SDS, and IGFBP-3 SDS, were not significantly different between patients with and without PTPN11 mutations.ConclusionAlthough this study included a relatively small number of patients, long-term rhGH therapy in NS patients was safe and effective at improving height, growth velocity, and serum IGF-1 levels, in accordance with previous studies. However, the meticulous monitoring of potential adverse events is still needed because of high dose of rhGH and preexisting hyperactivity of RAS-MAPK pathway. Patients with PTPN11 mutations demonstrated a decreased response to rhGH therapy compared to those without mutations.

The cardinal features of Turner syndrome (TS) are short stature, congenital abnormalities, infertility due to gonadal dysgenesis, with sex hormone insufficiency ensuing from premature ovarian failure, which is involved in lack of proper development of secondary sex characteristics and the frequent...... osteoporosis seen in Turner syndrome. But sex hormone insufficiency is also involved in the increased cardiovascular risk, state of physical fitness, insulin resistance, body composition, and may play a role in the increased incidence of autoimmunity. Severe morbidity and mortality affects females with Turner...... syndrome. Recent research emphasizes the need for proper sex hormone replacement therapy (HRT) during the entire lifespan of females with TS and new hypotheses concerning estrogen receptors, genetics and the timing of HRT offers valuable new information. In this review, we will discuss the effects...
