Background: As atypical polypoid adenomyoma (APA) has been reported to be a hormone-related tumor, we aimed to analyze the efficacy and safety of maintenance hormonal therapy after fertility-preserving treatment of these patients with medroxyprogesterone acetate (MPA). Methods: Data were retrospectively analyzed from patients with APA who were treated with a fertility-preserving regimen including MPA between October 2001 and December 2011. Eighteen patients were treated with MPA and 14 (77...

Risk of ovarian cancer with hormone therapy is associated with use of both unopposed estrogen therapy and combined estrogen-progestin therapy, whereas for endometrial cancer addition of continuous progestin decreases the estrogen induced increased risk. Less is known about risk with use of tibolone; a synthetic steroid with estrogenic, progestagenic, and androgenic properties. We assessed these associations in a prospective cohort study, including all Danish women 50-79 years of age and followed 1995-2009. National Danish Registers captured individually updated exposure information, cancer cases including histology and confounding factors...

Receptor-defined subtypes of breast cancer represent distinct cancer types and have differences in risk factors. Whether the two main hormonal forms of oral contraceptives (OCs); i.e. progestin-only (POC) and combined oral contraceptives (COC), are differentially associated with these subtypes are not well known. The aim of this study was to assess the effect of POC and COC use on hormone receptor-defined breast cancer risk in premenopausal women in a prospective population-based cohort - The Norwegian Women and Cancer study (NOWAC)...

PURPOSE OF REVIEW: Progestogen hypersensitivity (PH) is a rare disorder which usually occurs in women of childbearing age with symptoms ranging from urticaria with or without angioedema, multiple organ involvement consistent with allergic anaphylaxis, to a spectrum of other non-evanescent skin eruptions. In this review, we present a clinical vignette of PH and discuss the clinical presentation and proposed pathomechanisms, diagnosis, and treatment of PH. RECENT FINDINGS: The hypersensitivity symptoms are associated with exogenous progestin exposure (e...

In the last few years new oral contraceptives have been marketed showing a better safety profile for women. They are the result of important changes made to the old compounds. As far as the estrogenic component, with the aim of decreasing side effects, the dose of ethinyl estradiol has been reduced and synthetic estrogens have been replaced by natural estradiol, further improving the safety profile. Also the progestin component in the last years has been changed in terms of dose, endocrine and metabolic characteristics...

: A high risk of venous thromboembolism (VTE) recurrence requires extended anticoagulation but limits the options to control heavy menstrual bleeding (HMB) in women of reproductive age. We report the management of HMB in a 48-year-old woman with a history of menometrorrhagia, recurrent VTE and multiple VTE risk factors. Due to the occurrence of HMB during extended rivaroxaban treatment, the presence of a uterine fibroid and the contraindication to interrupt anticoagulation for high risk of VTE recurrence, she received hormonal treatment first with a gonadotropin-releasing hormone agonist and then with progestin...

With a diverse network of substrates, NUDIX hydrolases have emerged as a key family of nucleotide-metabolizing enzymes. NUDT5 (also called NUDIX5) has been implicated in ADP-ribose and 8-oxo-guanine metabolism and was recently identified as a rheostat of hormone-dependent gene regulation and proliferation in breast cancer cells. Here, we further elucidate the physiological relevance of known NUDT5 substrates and underscore the biological requirement for NUDT5 in gene regulation and proliferation of breast cancer cells...

INTRODUCTION: HIV affects more women than any other life-threatening infectious agent, and most infections are sexually transmitted. HIV must breach the female genital tract mucosal barrier to establish systemic infection, and clinical studies indicate virus more easily evades this barrier in women using depot-medroxyprogesterone acetate (DMPA) and other injectable progestins for contraception. Identifying a potential mechanism for this association, we learned DMPA promotes susceptibility of wild-type mice to genital herpes simplex virus type 2 (HSV-2) infection by reducing genital tissue expression of the cell-cell adhesion molecule desmoglein-1 (DSG-1) and increasing genital mucosal permeability...

In vertebrates, in addition to their classically reproductive functions, steroids regulate the immune system. This action is possible mainly due to the presence of steroid receptors in the different immune cell types. Much evidence suggests that the immune system of fish is vulnerable to xenosteroids, which are ubiquitous in the aquatic environment. In vivo and in vitro assays have amply demonstrated that oestrogens interfere with both the innate and the adaptive immune system of fish by regulating the main leukocyte activities and transcriptional genes...

The purpose of this study was to assess the proportion of patients satisfied with their treatment after a change from a low-dose oral contraceptive (OC) to norethisterone acetate (NETA) because of inefficacy of OC on pain symptoms. To this end, prospective, self-controlled study was conducted on 153 women using OC as a treatment for endometriosis and with persistence of one or more moderate or severe pain symptoms. At baseline and during 12 months after a shift from OC to oral NETA, 2.5 mg/d, pelvic pain was measured by means of a 0- to 10-point numerical rating scale and a multidimensional categorical rating scale...

Luminal breast cancers express estrogen (ER) and progesterone (PR) receptors, and respond to endocrine therapies. However, some ER+PR+ tumors display intrinsic or acquired resistance, possibly related to PR. Two PR isoforms, PR-A and PR-B, regulate distinct gene subsets that may differentially influence tumor fate. A high PR-A:PR-B ratio is associated with poor prognosis and tamoxifen resistance. We speculate that excessive PR-A marks tumors that will relapse early. Here we address mechanisms by which PR-A regulate transcription, focusing on SUMOylation...

Sex hormones play an important role in establishing sex-distinctive brain structural and functional variations that could contribute to the sex differences in alcohol consumption behavior. Here, we systematically reviewed articles that studied sex hormone impacts on alcohol consumption and alcohol use disorder (AUD). An extensive literature search conducted in MEDLINE, PubMed, Scopus and CINAHL databases identified 776 articles, which were then evaluated for pre-specified criteria for relevance and quality assurance...

While progesterone receptor (PR)-targeted therapies are modestly active in patients with uterine cancer, their underlying molecular mechanisms are not well understood. The clinical use of such therapies is limited because of the lack of biomarkers that predict response to PR-agonists (progestins) or PR-antagonists (onapristone). Thus, understanding the underlying molecular mechanisms of action will provide an advance in developing novel combination therapies for cancer patients. Nuclear translocation of PR has been reported to be ligand-dependent or -independent...

Importance: 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...
