RESUMO

PURPOSE: Gender Incongruence (GI) is a marked and persistent incongruence between an individual's experienced and the assigned gender at birth. In the recent years, there has been a considerable evolution and change in attitude as regards to gender nonconforming people. METHODS: According to the Italian Society of Gender, Identity and Health (SIGIS), the Italian Society of Andrology and Sexual Medicine (SIAMS) and the Italian Society of Endocrinology (SIE) rules, a team of experts on the topic has been nominated by a SIGIS-SIAMS-SIE Guideline Board on the basis of their recognized clinical and research expertise in the field, and coordinated by a senior author, has prepared this Position statement. Later on, the present manuscript has been submitted to the Journal of Endocrinological Investigation for the normal process of international peer reviewing after a first internal revision process made by the SIGIS-SIAMS-SIE Guideline Board. RESULTS: In the present document by the SIGIS-SIAMS-SIE group, we propose experts opinions concerning the psychological functioning, gender affirming hormonal treatment, safety concerns, emerging issues in transgender healthcare (sexual health, fertility issues, elderly trans people), and an Italian law overview aimed to improve gender non-conforming people care. CONCLUSION: In this Position statement, we propose experts opinions concerning the psychological functioning of transgender people, the gender-affirming hormonal treatment (full/partial masculinization in assigned female at birth trans people, full/partial feminization and de-masculinization in assigned male at birth trans people), the emerging issues in transgender health care aimed to improve patient care. We have also included an overview of Italian law about gender affirming surgery and registry rectification.

RESUMO

SUMMARY: With an estimated 3.8 million breast cancer survivors in the United States, obstetrician-gynecologists often are on the front lines of addressing survivorship issues, including the hypoestrogenic-related adverse effects of cancer therapies or early menopause in survivors (1). Although systemic and vaginal estrogen are used widely for symptomatic relief of genitourinary syndrome of menopause in the general population, among individuals with a history of hormone-sensitive cancer, there is uncertainty about the safety of hormone-based therapy, leading many individuals with bothersome symptoms to remain untreated, with potential negative consequences on quality of life (2). An effective management strategy requires familiarity with a range of both hormonal and nonhormonal treatment options, knowledge about the pharmaceutical mechanisms of action, and the ability to tailor treatment based on individual risk factors. This clinical consensus document was developed using an a priori protocol in conjunction with two authors specializing in urogynecology and gynecologic oncology. This document has been updated to review the safety and efficacy of newer hormonal treatment options as well as nonhormonal modalities.

RESUMO

BACKGROUND: Obesity rates and weight changes in adults on gender-affirming hormone therapy are lacking or limited by small sample sizes, duration, and location. SUBJECTS/METHODS: This longitudinal study followed the body mass index and body weights of 470 transgender and gender-diverse adult patients (247 transfeminine and 223 transmasculine; mean age, 27.8 years) seen at a Federally Qualified Health Center and an academic endocrinology practice, both in Washington DC USA. Body weight and body mass index were recorded at baseline and at multiple follow-up clinical visits up to 57 months after the initiation of gender-affirming hormone therapy. The outcomes of this study were the changes to body weight and obesity rates following hormone therapy. RESULTS: Within 2-4 months of starting gender-affirming hormone therapy, the mean body weight increased in the transmasculine group by 2.35 (1.15-3.55) kg and further increased beyond 34 months. Among the transfeminine group, the mean body weight was stable for the first 21 months of hormone therapy and then began to steadily increase, particularly in those under 30 years old. The prevalence of obesity at baseline was 25% in the transfeminine group and 39% in the transmasculine group. Following the initiation of hormone therapy, rates of obesity ranged from 42 to 52% among the transmasculine group and 21 to 30% among transfeminine group. Following 11-21 months of hormone therapy, weight gain ≥5 kg was seen among 21% of transfeminine individuals and 30% of transmasculine individuals. CONCLUSIONS: As compared with transfeminine individuals, transmasculine individuals have greater rates of obesity and weight gain before and during hormone therapy. Body weight and body mass index should be routinely monitored before and after the initiation of gender-affirming hormone therapy. Multidisciplinary weight-reduction interventions should be promoted where appropriate.

RESUMO

Importance: Benign breast diseases (BBDs) are common and associated with breast cancer risk, yet the etiology and risk of BBDs have not been extensively studied. Objective: To investigate the risk of BBDs by age, hormonal factors, and family history of breast cancer. Design, Setting, and Participants: This retrospective cohort study assessed 70 877 women from the population-based Karolinska Mammography Project for Risk Prediction of Breast Cancer (KARMA) who attended mammographic screening or underwent clinical mammography from January 1, 2011, to March 31, 2013, at 4 Swedish hospitals. Participants took part in a comprehensive questionnaire on recruitment. All participants had complete follow-up through high-quality Swedish national registers until December 31, 2015. Pathology medical records on breast biopsies were obtained for the participants, and BBD subtypes were classified according to the latest European guidelines. Analyses were conducted from January 1 to July 31, 2020. Exposures: Hormonal risk factors and family history of breast cancer. Main Outcomes and Measures: For each BBD subtype, incidence rates (events per 100 000 person-years) and multivariable Cox proportional hazards ratios (HRs) with time-varying covariates were estimated between the ages of 25 and 69 years. Results: A total of 61 617 women within the mammographic screening age of 40 to 69 years (median age, 53 years) at recruitment with available questionnaire data were included in the study. Incidence rates and risk estimates varied by age and BBD subtype. At premenopausal ages, nulliparity (compared with parity ≥3) was associated with reduced risk of epithelial proliferation without atypia (EP; HR, 0.62; 95% CI, 0.46-0.85) but increased risk of cysts (HR, 1.38; 95% CI, 1.03-1.85). Current and long (≥8 years) oral contraceptive use was associated with reduced premenopausal risk of fibroadenoma (HR, 0.65; 95% CI, 0.47-0.90), whereas hormone replacement therapy was associated with increased postmenopausal risks of epithelial proliferation with atypia (EPA; HR, 1.81; 95% CI, 1.07-3.07), fibrocystic changes (HR, 1.60; 95% CI, 1.03-2.48), and cysts (HR, 1.98; 95% CI, 1.40-2.81). Furthermore, predominantly at premenopausal ages, obesity was associated with reduced risk of several BBDs (eg, EPA: HR, 0.31; 95% CI, 0.17-0.56), whereas family history of breast cancer was associated with increased risk (eg, EPA: HR, 2.11; 95% CI, 1.48-3.00). Conclusions and Relevance: These results suggest that the risk of BBDs varies by subtype, hormonal factors, and family history of breast cancer and is influenced by age. Better understanding of BBDs is important to improve the understanding of benign and malignant breast diseases.

RESUMO

The objective of this project is to create eligibility criteria for the use of menopausal hormone therapy (MHT) similar to those established for contraceptive methods. A consortium of scientific societies coordinated by the Spanish Menopause Society met to formulate recommendations for the use of MHT by patients with medical conditions based on the best available evidence. The project protocol, which was registered in the Open Science Framework platform (DOI 10.17605/OSF.IO/J6WBC), will be conducted in two phases. As a first step we will conduct a series of systematic reviews on the safety of MHT, addressing eight clinical questions. The findings of these systematic reviews will help to inform a structured process in which a panel of experts will define the eligibility criteria according to a specific framework, which will facilitate the discussion and development process. For the first time, a set of eligibility criteria, based on clinical evidence and developed according to the most rigorous methodological tools, will be defined. This will provide health professionals with a powerful decision-making tool that can be used in the management of menopausal symptoms.

RESUMO

BACKGROUND: It remains under subject of debate regarding the optimal route of luteal support for hormone replacement therapy- frozen embryo transfer (HRT-FET) cycles. We compared efficacy of vaginal progesterone gel combined with oral dydrogesterone and intramuscular progesterone for HRT-FET lutein support. METHODS: This is a retrospective observational study. After matching for propensity score of getting vaginal + oral treatment, a total of 208 FET cycles in the vaginal progesterone combined with oral dydrogesterone and 624 cycles in the intramuscular progesterone group were enrolled. Pregnancy outcomes and neonatal outcomes including chemical pregnancy rate, clinical pregnancy rate, implantation rate, spontaneous abortion rate, live birth rate, gestational weeks, pre-term delivery, birth weight, and congenital anomalies rate were compared. RESULTS: No significant differences were observed in patient characteristics such as age, duration of infertility, type of infertility, or hormone level after matching. Chemical pregnancy rate (68.3 % versus 70.5 %), clinical pregnancy rate (64.9 % versus 64.4 %), implantation rate (52.3 % versus 50.2 %), spontaneous abortion rate (21.5 % versus 18.4 %), and live birth rate (49.0 % versus 51.3 %) were similar in both group without statistically significant difference. No significant differences in neonatal outcomes were observed between the two groups. CONCLUSION: We observed similar pregnancy outcomes in both vaginal progesterone gel combined with oral dydrogesterone and intramuscular progesterone protocol. Vaginal progesterone gel combined with oral dydrogesterone can be substituted for intramuscular progesterone given that vaginal plus oral use has good safety and is more convenient and may be associated with less side effect caused by intramuscular injection.

RESUMO

This study aimed to identify the pathological outcomes and survival benefits of neoadjuvant hormone therapy (NHT) combined with radical prostatectomy (RP) and radiotherapy (RT) administered to patients with high-risk prostate cancer (HRPCa). We searched PubMed, Embase, and the Cochrane Library for studies comparing NHT plus RP or RT with RP or RT alone, administered to patients with HRPCa. We used a random-effects model to compute risk estimates with 95% confidence intervals (CIs) and quantified heterogeneity using the I "2" statistic. Subgroup and sensitivity analyses were performed to identify potential sources of heterogeneity. We selected 16 studies. NHT before RP significantly decreased lymph node involvement (risk ratio [RR] = 0.69, 95% CI: 0.56-0.87) and increased the rates of pathological downstaging (RR = 2.62, 95% CI: 1.22-5.61) and organ-confinement (RR = 2.24, 95% CI: 1.54-3.25), but did not improve overall survival and biochemical progression-free survival (bPFS). The administration of NHT before RT to patients with HRPCa was associated with significant benefits for cancer-specific survival (hazard ratio [HR] = 0.51, 95% CI: 0.39-0.68), disease-free survival (HR = 0.51, 95% CI: 0.44-0.60), and bPFS (HR = 0.54, 95% CI: 0.46-0.64). Short-term NHT combined with RT administered to patients with HRPCa conferred significant improvements. Although the advantage of local control was observed when NHT was administered before RP, there was no significant survival benefit associated with HRPCa. Therefore, short-term NHT combined with RT is recommended for implementation in standard clinical practice but not for patients who undergo RP.

RESUMO

Adrenal insufficiency (AI) requires life-long treatment with glucocorticoid replacement therapy. Over- or under-substitution carries the risk of increased morbidity in the form of side effects or adrenal crises. Glucocorticoid replacement therapy needs to be flexible with dose adaptation in special situations. This could not be managed by medical personnel on a daily basis, but requires an educated patient who has a good knowledge of the disease, understands his medical therapy and is able to perform situational dose adaptation. The rarity of the disease in combination with the need to respond to stressful situations with rapid glucocorticoid dose adjustment underlines that a well-trained patient is crucial for optimal management of the disease.In this literature review we provide background information further clarifying the need of education in patients with AI including the current shortcomings of medical therapy and of the treatment of patients with AI. We outline the aims of therapeutic patient education, present the concept of structured patient education in Germany, and discuss available results of patient group education programs. Furthermore, we propose strategies how therapeutic patient education for adrenal insufficiency can be organized under COVID-19 pandemic conditions.

RESUMO

Since the introduction of sensitive assays for serum thyroid-stimulating hormone (TSH) clinicians have advised hypothyroid patients to adjust the dose of levothyroxine (L-T4) in order to achieve a normal serum TSH. A minority of patients are dissatisfied with this treatment strategy and experience symptoms. Some indirect evidence suggests that a normal serum TSH may not necessarily reflect euthyroidism at the tissue level in patients treated with L-T4. Increasingly hypothyroid patients demand higher doses of L-T4 or liothyronine (L-T3) or animal thyroid extract, often purchased online, and titrate the dose against symptoms, although ample evidence suggests that combination treatment (L-T4 with L-T3) is no more effective than L-T4 alone. Community surveys show that up to 53% of treated hypothyroid patients at any time have a serum TSH outside the normal range. The recommendation by guidelines that the upper limit of the normal range for serum TSH should not be exceeded is supported by robust evidence and is generally accepted by clinicians and patients. However, until recently the lower limit of serum TSH for optimal L-T4 replacement has been controversial. New evidence obtained by two independent large population studies over the past two years has shown that mortality of hypothyroid patients treated with levothyroxine is increased when the serum TSH exceeds or is reduced outside the normal reference range. It is estimated that the implementation of a policy of normalising serum TSH in hypothyroid patients will reduce the risk of death of 28.3 million people in the USA and Europe alone.

RESUMO

OBJECTIVE: Using real-world data from patients with growth hormone deficiency (GHD), we evaluated whether clinical practice in France adheres to international guidelines regarding somatropin dose adjustment, and assessed the long-term effectiveness and safety of somatropin. METHODS: Data were obtained from a national prospective systematic longitudinal routine follow-up programme of naive/non-naive adults with childhood-onset (CO) or adult-onset (AO) GHD treated with Norditropin® (Novo Nordisk A/S). RESULTS: Between 2003 and 2006, 331 treatment-naive and non-naive adults with severe GHD were enrolled and followed for a median duration of approximately 5 years; 328 patients were available for analysis. At baseline, mean patient age was 39.2 years; median standard deviation score (SDS) for insulin-like growth factor-1 (IGF-1) level was -2.2 in naive patients, subsequently fluctuating between -0.1 and +0.3 SDS during the study period. Mean GH doses ranged between 0.25 and 0.51mg/day (naive patients) and 0.39 and 0.46mg/day (non-naive patients). Despite generally receiving a higher somatropin dose, women (naive/non-naive) tended to have lower IGF-1 levels than men. Median somatropin dose was consistently higher in patients with CO-GHD than patients with AO-GHD. Extreme IGF-1 values (<-2 or >+2 SDS) were not systematically accompanied by somatropin dose adjustments. Waist circumference improved in approximately one third of patients, at a mean 3.5 years. Somatropin was well tolerated; there were no cardiovascular or cerebrovascular events during the 5-year analysis period. CONCLUSION: Current clinical practice of physicians in France follows international guidelines regarding somatropin dose adjustment in adults with GHD. However, dose adjustments are not always sufficient, notably in women, and treatment effects may have been delayed due to low somatropin dose (Clinical trial registration NCT01580605).

RESUMO

PURPOSE OF REVIEW: Hypogonadism is highly prevalent among not only patients with a history of prior treatment for cancer, but also among those patients with a new oncologic diagnosis who have not yet received any cancer therapy. Hypogonadism can cause a wide array of signs and symptoms including: deceased muscle mass; increased fat mass; decreased energy, mood, and overall sense of well being; diminished bone mineral density; infertility; and impaired libido and sexual function. This purpose of this manuscript is to review the mechanisms by which cancer and oncologic treatment regimens can adversely affect the hypothalamic pituitary gonadal axis, resulting in hypogonadism. Risks and benefits associated with the treatment of testosterone deficiency are also discussed, which are important considerations for clinicians caring for affected patients. RECENT FINDINGS: Hypogonadism has a high prevalence in the setting of cancer and is an important survivorship issue. Recent randomized controlled trials confirm testosterone's therapeutic benefits in terms of sexual function, mood body composition, and bone health, but the specific benefits in terms of quality of life are less clear. SUMMARY: More prospective studies are needed to further delineate the risks, benefits, and overall outcomes of testosterone replacement therapy in patients with cancer and cancer survivors.

RESUMO

PURPOSE OF REVIEW: The incidence of testosterone deficiency and number of men on testosterone therapy (TTh) has increased significantly over the past 3 decades. This rise has been accompanied by controversies surrounding the indications and possible adverse effects of therapy. To better inform prescribing habits among providers, many major medical associations have devised guidelines regarding the diagnosis and management of testosterone deficiency. While these guidelines agree in many areas, there are some key differences that should be identified. This review will explore the similarities, differences, and rationale for these guidelines. RECENT FINDINGS: Over the past 7 years, much attention has been devoted to the implications of TTh on cardiac health. All reviewed guidelines include dedicated sections discussing these implications and the society's position on prescribing testosterone considering recent findings, however, differ on specific contraindications to TTh and when to initiate therapy after a cardiovascular event. In addition, the American College of Physicians released its first guideline earlier this year which may impact prescribing habits among primary care physicians. SUMMARY: The differences between testosterone deficiency guidelines may indicate gaps in our knowledge of testosterone deficiency and focuses of future research efforts. Prescribers should be aware of these differences and discuss all treatment options with their patients.

RESUMO

CONTEXT: Accurate hydrocortisone dosing in children with adrenal insufficiency is important to avoid the risks of over and under treatment including iatrogenic Cushing's syndrome and adrenal crisis. OBJECTIVE: To establish a population pharmacokinetic model of hydrocortisone in children and use this to refine hydrocortisone replacement regimens. DESIGN AND METHODS: Pharmacokinetic study of hydrocortisone granules, available in 0.5, 1, 2 and 5 mg dose strengths, in 24 children with adrenal insufficiency aged 2 weeks to 6 years. Cortisol concentrations quantified by LC-MS/MS were used to refine an adult pharmacokinetic model to a paediatric population model which was then used to simulate seven different hydrocortisone treatment regimens. RESULTS: Pre-dose cortisol levels were undetectable in 54% of the 24 children. The developed pharmacokinetic model had good predictive performance. Simulations for the seven treatment regimens using either three- or four-times daily dosing showed treatment regimens delivered an AUC0-24h within the 90% reference range for healthy children except in neonates where two regimens had an AUC below the 5th percentile. Cortisol concentrations at individual time points in the 24 h were outside the 90% reference range for healthy individuals in 50%, 55-65% and 70-75% for children, infants and neonates, respectively, with low cortisol levels being most prevalent. CONCLUSIONS: Current paediatric hydrocortisone treatment regimens based on either three- or four-times daily administration replicate cortisol exposure based on AUC0-24h, but the majority of cortisol levels are above or below physiological cortisol levels with low levels very common before the next dose.

RESUMO

CONTEXT: It is well recognized that some hypothyroid patients on levothyroxine (LT4) remain symptomatic, but why patients are susceptible to this condition, why symptoms persist, and what is the role of combination therapy with LT4 and liothyronine (LT3), are questions that remain unclear. Here we explore evidence of abnormal thyroid hormone (TH) metabolism in LT4-treated patients, and offer a rationale for why some patients perceive LT4 therapy as a failure. EVIDENCE ACQUISITION: This review is based on a collection of primary and review literature gathered from a PubMed search of "hypothyroidism," "levothyroxine," "liothyronine," and "desiccated thyroid extract," among other keywords. PubMed searches were supplemented by Google Scholar and the authors' prior knowledge of the subject. EVIDENCE SYNTHESIS: In most LT4-treated patients, normalization of serum thyrotropin levels results in decreased serum T3/T4 ratio, with relatively lower serum T3 levels; in at least 15% of the cases, serum T3 levels are below normal. These changes can lead to a reduction in TH action, which would explain the slower rate of metabolism and elevated serum cholesterol levels. A small percentage of patients might also experience persistent symptoms of hypothyroidism, with impaired cognition and tiredness. We propose that such patients carry a key clinical factor, for example, specific genetic and/or immunologic makeup, that is well compensated while the thyroid function is normal but might become apparent when compounded with relatively lower serum T3 levels. CONCLUSIONS: After excluding other explanations, physicians should openly discuss and consider therapy with LT4 and LT3 with those hypothyroid patients who have persistent symptoms or metabolic abnormalities despite normalization of serum thyrotropin level. New clinical trials focused on symptomatic patients, genetic makeup, and comorbidities, with the statistical power to identify differences between monotherapy and combination therapy, are needed.

RESUMO

BACKGROUND: Late-onset hypogonadism (LOH) is a syndrome characterized by clinical and biochemical evidence of low testosterone levels with advancing age. In recent years, several guidelines, position statements and other recommendations have become available. It is unclear whether similar indications are reported in these documents. OBJECTIVE: To review similarities and differences among available documents on the management of hypogonadism, with a special focus on LOH. MATERIALS AND METHODS: PubMed, Google and international societies websites were searched on March 2020 for documents published in the last 10 years on the management of hypogonadism and LOH. RESULTS: Nine documents were found, each developed by: (a) the American Urological Association; (b) the British Society for Sexual Medicine; (c) the Canadian Medical Association; (d) the Endocrine Society; (e) the Endocrine Society of Australia; (f) the European Academy of Andrology; (g) the European Association of Urology; (h) the International Consultation for Sexual Medicine; and (i) the International Society for the Study of Aging Male. DISCUSSION: Despite similar principles, differences were found both for the diagnostic workup and follow-up. Particularly, discrepancies were reported both for total and free testosterone levels for diagnosis and for total testosterone for monitoring. CONCLUSION: Available documents differ in terms of specific recommendations for the management of hypogonadism and LOH. Given the relevant clinical implications of adequate management of these disorders, future guidelines should report more consistent measures to be adopted in clinical practice.

RESUMO

The goal of this study was to review relevant randomized controlled trials in order to determine the clinical efficacy of levothyroxine in the treatment of overt or subclinical hypothyroidism. Using appropriate keywords, we identified relevant studies using PubMed, the Cochrane library, and Embase. Key pertinent sources in the literature were also reviewed, and all articles published through December 2019 were considered for inclusion. For each study, we assessed odds ratios (ORs), mean difference (MD), and 95% confidence interval (95%CI) to assess and synthesize outcomes. We included 25 studies with totally 1,735 patients in the meta-analysis. In the patients with hypothyroidism, compared with L-T4, L-T4 plus L-T3 significantly decreased TSH levels and increased FT3 levels. Compared with placebo, L-T4 significantly increased FT4 levels and decreased TSH levels. In patients with subclinical hypothyroidism, compared with placebo, L-T4 significantly decreased SBP, TSH, T3 and TC and increased FT3 and FT4.
