PURPOSE: The efficacy and thrombogenicity of transdermal estradiol in the management of refractory uremic bleeding in adults are examined. SUMMARY: Platelet dysfunction from chronic kidney disease may induce uremic bleeding. This type of bleeding may involve the skin, oral and nasal mucosa, gingivae, respiratory system, and gastrointestinal or urinary tract. While the mainstay of treatment for uremic bleeding primarily involves dialysis and use of prohemostatic agents such as desmopressin and erythropoiesis-stimulating agents, certain patients may experience bleeding refractory to these interventions...

We report an uncommon case of deep infiltrating endometriosis of the colon presenting as iron deficiency anemia nine years after hysterectomy with bilateral salpingo-oophorectomy. The endometrial implant was found at the hepatic flexure, an exceedingly rare location for endometriosis invasion with no cases distinctly reported in the literature. Additionally, the presentation of gastrointestinal endometriosis as iron deficiency anemia is not well documented in the literature. Instead of surgery, we prescribed a novel medical therapeutic approach using conjugated estrogen-bazedoxifene to antagonize the proliferative effects of estrogen on endometrial tissue...

OBJECTIVE: This review describes historical development of selective estrogen receptor modulators (SERMs) and their combination with estrogens, termed a tissue selective estrogen complex (TSEC), and considers the potential for future TSEC development. METHODS: This narrative review is based on literature identified on PubMed and the TSEC research and development experience of the authors. RESULTS: SERMs have estrogenic and antiestrogenic effects in various tissues; however, no single agent has achieved an optimal balance of agonist and antagonist effects for the treatment of menopausal symptoms...

Context: Most girls with Turner Syndrome have hypergonadotropic hypogonadism and need hormonal replacement - for induction of puberty and later maintaining secondary sex characteristics, attaining peak bone mass, and uterine growth. The optimal estrogen replacement regimen is still being studied. Evidence Acquisition: We conducted a systematic search of PubMed for research related to TS and puberty, including key words: estrogen, growth, puberty. Evidence Synthesis: The goals of replacement are to mimic normal timing and progression of physical and social development while minimizing risks...

In the present study we comprehensively characterize intratesticular sex steroid production, metabolism and receptors in the domestic cat to elucidate the role of testosterone, estradiol and progesterone in testis development, steroid synthesis and spermatogenesis. There is a great demand for new concepts of fertility control in domestic (feral) cats and wild felids. The acquired knowledge will help to understand the regulation of spermatogenesis in felids, and may reveal new target points for male contraception...

Oxidative stress has been proposed to play a key role in malignant hyperthermia (MH), a syndrome caused by excessive Ca2+ release in skeletal muscle. Incidence of mortality in male calsequestrin-1 knockout (CASQ1-null) mice during exposure to halothane and heat (a syndrome closely resembling human MH) is far greater than that in females. To investigate the possible role of sex hormones in this still unexplained gender difference, we treated male and female CASQ1-null mice for 1 month, respectively, with Premarin (conjugated estrogens) and leuprolide (GnRH analog) and discovered that during exposure to halothane and heat Premarin reduced the mortality rate in males (79-27% and 86-20%), while leuprolide increased the incidence of mortality in females (18-73% and 24-82%)...

BACKGROUND: In recent years, compounded bioidentical hormone therapy (CBHT) has emerged as a popular alternative to manufactured, FDA approved hormone therapy (HT)-despite concerns within the medical community and the availability of new FDA approved "bioidentical" products. This study aims to characterize the motivations for using CBHT in a U.S. sample of ordinary midlife women. METHODS: We analyze data collected from 21 current and former users of CBHT who participated in a larger qualitative study of menopausal decision-making among U...

Context: Estrogens affect the incidence and progression of colorectal cancer (CRC), although the precise molecular mechanisms remain ill-defined. Objective: The present study investigated prereceptor estrogen metabolism through steroid sulphatase (STS) and 17β-hydroxysteroid dehydrogenase activity and subsequent nongenomic estrogen signaling in human CRC tissue, in The Cancer Genome Atlas colon adenocarcinoma data set, and in in vitro and in vivo CRC models. We aimed to define and therapeutically target pathways through which estrogens alter CRC proliferation and progression...

Estrogen conjugates are precursors of free estrogens such as 17ß-estradiol (E2) and estrone (E1), which cause potent endocrine disrupting effects on aquatic organisms. In this study, microcosm laboratory experiments were conducted at 25°C in an agricultural soil to investigate the aerobic degradation and metabolite formation kinetics of 17ß-estradiol-3-glucuronide (E2-3G) and 17ß-estradiol-3-sulfate (E2-3S). The aerobic degradation of E2-3G and E2-3S followed first-order kinetics and the degradation rates were inversely related to their initial concentrations...

Poultry manure contains free and conjugated forms of the natural estrogens 17β-estradiol and estrone, which can be transported to receiving waters via runoff when land-applied. Previous studies have demonstrated estrogens in runoff from poultry manure-amended fields but have not tracked changes in estrogenicity within this water over time. Microbial conversion of conjugated estrogens (a major portion of water-extractable estrogens) to parent forms may result in temporary increases in estrogenicity in natural water bodies...

OBJECTIVE: Conjugated estrogens/bazedoxifene (CE/BZA) has demonstrated benefit in vulvar-vaginal atrophy (VVA, part of genitourinary syndrome of menopause) and the sexual function domain of the Menopause-specific Quality of Life (MENQOL) questionnaire. The study's objective was to determine the relationship of VVA symptoms and clinical parameters with MENQOL sexual functioning in postmenopausal women receiving VVA treatment. STUDY DESIGN: Post hoc analysis data were derived from the 12-week SMART-3 trial, which evaluated CE/BZA's effect on VVA in nonhysterectomized postmenopausal women (aged 40-65 years) experiencing one or more moderate to severe VVA symptoms (dryness, itching/irritation, pain with intercourse) and vaginal pH>5...

Hormone replacement therapy (HRT) affects the incidence and potential progression of colorectal cancer (CRC). As HRT primarily consists of estrone sulfate (E1S), understanding whether this conjugated estrogen is transported and metabolized in CRC will define its potential effect in this malignancy. Here, we show that a panel of CRC cell lines (Colo205, Caco2, HCT116, HT-29) have steroid sulfatase (STS) activity, and thus can hydrolyze E1S. STS activity is significantly higher in CRC cell lysate, suggesting the importance of E1S transport in intracellular STS substrate availability...

Background: Hemorrhagic cystitis (HC) is one of the most challenging complications in hematopoietic stem cell transplantation (HSCT). Estrogen is one of the suggested treatments for controlling this problem. Subjects and Methods: We performed a randomized case-control study to evaluate the efficacy of oral conjugated estrogen on HC management in 56 HSCT patients. Patients were randomly assigned to the drug group (received 6.25 mg conjugated estrogen oral tablets in a daily single dose during hematuria period) or control group...

The immunologic potency of IgG is modulated by glycosylation, but mechanisms regulating this process are undefined. A role for sex hormones is suggested by differences in IgG glycans between women and men, most prominently with respect to galactose. We therefore assessed IgG galactosylation in 713 healthy adults from 2 cohorts as well as in 159 subjects from 4 randomized controlled studies of endocrine manipulation: postmenopausal women receiving conjugated estrogens, raloxifene, or placebo; premenopausal women deprived of gonadal hormones with leuprolide and treated with estradiol or placebo; men deprived of gonadal hormones with goserelin and given testosterone or placebo; and men deprived of gonadal hormones with goserelin and given testosterone or placebo together with anastrozole to block conversion of testosterone to estradiol...
