Osteoporosis and Bone Health in Transgender Persons

Evaluating changes in body composition, bone mass, and metabolic profile in an animal model undergoing transfeminine hormone therapy and physical exercise

BACKGROUND & AIMS

Gender-affirming hormone therapy (GAHT) is essential for transgender individuals seeking body modifications. For transfeminine people assigned male at birth, GAHT typically involves a combination of antiandrogens and estrogens. Despite its importance, the scientific literature presents inconsistencies regarding the effects of these hormones on nutritional status, body composition, and biochemical markers. This study aims to evaluate the impact of estradiol enanthate and dihydroxyprogesterone acetophenide (E2EN/DHPA) hormonal treatment, in conjunction with resistive physical exercise, on body composition and metabolic profiles.

METHODS

Twenty-eight male rats were divided into three groups: MO (control group, n = 8), receiving sesame oil vehicle; MH (n = 11), receiving E2EN/DHPA; and MEH (n = 9), receiving E2EN/DHPA along with physical exercise. The hormonal treatment was administered every ten days for two months, while the exercise regimen involved stair climbing with progressively increasing weights, performed five times weekly for seven weeks. Evaluated parameters included body mass index (BMI), body composition (fat and lean mass), bone mineral density (BMD), and lipid profile (triglycerides, HDL-C, LDL-C).

RESULTS

The rats that received E2EN/DHPA showed significant changes in body composition and BMI, regardless of exercise. The MH group had increased body fat, while both the MH and MEH groups had decreased bone area and mineral content. However, BMD remained the same across all groups. Elevated triglyceride levels were observed, and the MEH group also had reduced LDL-C levels. HDL-C levels did not show significant variation.

CONCLUSION

The study's findings show similarities to changes seen in transfeminine individuals undergoing GAHT with estrogen and antiandrogens. These changes include decreased muscle mass, increased body fat, preserved bone mineral density, and elevated triglycerides. The study also found that resistance exercise positively impacted lipid profiles, particularly in reducing LDL-C. These results highlight the need for further research and comparative trials on hormone therapy regimens.

Transgender and Gender Diverse Medical Education in Radiology: A Systematic Review

RATIONALE AND OBJECTIVES

Physicians report a lack of Transgender and Gender Diverse (TGD) health competency for medical imaging. This knowledge gap contributes to negative medical imaging experiences, discrimination, stigma, and diagnostic errors for TGD individuals. Medical education plays an important role in improving this. However, the current landscape and gaps in TGD medical education in radiology is underexplored. We aimed to fill the knowledge gap on the current state of TGD medical education in radiology.

MATERIALS AND METHODS

A PRISMA and SWiM guideline-compliant systematic review on TGD medical education in radiology was performed. Four databases were searched: Medline, Embase, Web of Science, and Scopus from inception to May 13, 2024. Article screening and extraction occurred independently and in duplicate. Narrative synthesis was performed on TGD medical education material in radiology, educational recommendations, barriers/enablers to education, and current guidelines.

RESULTS

A total of 4360 records were identified with 76 articles included. Most articles (52, 68%) were from the United States. Most articles aimed to provide recommendations for TGD medical education in radiology (53, 69.7%). Some articles focused on developing medical education (7, 9.2%), evaluating medical education (7, 9.2%), evaluating guidelines (8, 10.5%), or developing guidelines (3, 4%). Identified TGD medical education in radiology is inconsistent, focusing on terminology guides, clinical scenarios, and cultural sensitivity workshops. Many current guidelines for TGD medical imaging were developed through extrapolation of guidance for cisgender patients, demonstrating limited relevance and meaningfulness for TGD patients.

CONCLUSION

This systematic review identifies a need to develop consistent TGD medical educational material in radiology in partnership with TGD patients to cover patient perspectives and guidance for medical imaging considerations. Results can be used to identify TGD medical education resources in radiology which may be helpful, and guide development of future medical education.

Getting old in the desired gender: a systematic review on aging diseases in transgender people

INTRODUCTION

The growing demographic presence of the transgender (TGD) population has sparked an increase in clinical investigations focusing on the impacts of gender-affirming hormone therapy (GAHT) in adults with gender dysphoria. Despite this surge in studies, there remains a significant gap in the literature regarding the health status of older TGD individuals. This review aims to assess prevalent pathological conditions within the TGD population, specifically concentrating on aging-related diseases investigated to date.

METHODS

A systematic search across Embase Ovid, Scopus, PubMed, Cochrane Library, and Web of Science databases was conducted to identify articles reporting on the aging process in TGD individuals. Methodological quality was evaluated using Newcastle-Ottawa Scale (NOS) scores.

RESULTS

Initial database searches yielded 12,688 studies, which were refined to 18 through elimination of duplicates and title/abstract review. Following a comprehensive appraisal, nine studies were included in the systematic review. These articles, published between 2017 and 2023, involved a total of 5403 participants. The evidence indicates a noteworthy percentage of the TGD population being at risk for cardiovascular diseases, experiencing depression or disability, and demonstrating hesitancy toward major recommended screening programs.

CONCLUSIONS

Limited studies on older TGD individuals highlight not only an organic risk of chronic diseases but also a cognitive/psychiatric risk that should not be underestimated. Further research is imperative to deepen our understanding of the pathophysiological mechanisms involved in the health challenges faced by older TGD individuals.

Systematic Review of Gender and Sex Terminology Use in Arthroplasty Research: There Is Room for Improvement

BACKGROUND

There is increasing appreciation of the distinction between gender and sex as well as the importance of accurately reporting these constructs. Given recent attention regarding transgender and gender nonconforming (TGNC) and intersex identities, it is more necessary than ever to understand how to describe these identities in research. This study sought to investigate the use of gender- and sex-based terminology in arthroplasty research.

METHODS

The 5 leading orthopaedic journals publishing arthroplasty research were reviewed to identify the first twenty primary clinical research articles on an arthroplasty topic published after January 1, 2022. Use of gender- or sex-based terminology, whether use was discriminate, and whether stratification or adjustment based on gender or sex was performed, were recorded.

RESULTS

There were 98 of 100 articles that measured a construct of gender or sex. Of these, 15 articles used gender-based terminology, 45 used sex-based terminology, and 38 used a combination of gender- and sex-based terminology. Of the 38 articles using a combination of terminology, none did so discriminately. All articles presented gender and sex as binary variables, and 2 attempted to explicitly define how gender or sex were defined. Of the 98 articles, 31 used these variables for statistical adjustments, though only 6 reported stratified results.

CONCLUSIONS

Arthroplasty articles infrequently describe how gender or sex was measured, and frequently use this terminology interchangeably. Additionally, these articles rarely offer more than 2 options for capturing variation in sex and gender. Future research should be more precise in the treatment of these variables to improve the quality of results and ensure findings are patient-centered and inclusive.

Association between hepatitis A seropositivity and bone mineral density in adolescents and adults: a cross-sectional study using NHANES data

BACKGROUND

Osteoporosis, characterized by decreased bone density and increased fracture risk, imposes significant physical, psychosocial, and financial burdens. Early detection and prevention are crucial for managing osteoporosis and reducing the risk of fractures.

OBJECTIVES

To investigate the relationship between Hepatitis A seropositivity and bone mineral density (BMD) in adolescents and adults and to explore the potential link between Hepatitis A infection and osteoporosis risk.

DESIGN AND SETTING

This cross-sectional study used data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 to evaluate the association between hepatitis A seropositivity and BMD in 15,693 participants.

METHODS

Multivariable regression analysis was used to calculate the mean BMD and standard error for adolescents and adults, followed by an independent z-test to determine whether there was a significant difference between the seropositive and seronegative groups.

RESULTS

Hepatitis A seropositive adolescents and adults had lower BMD than their seronegative counterparts, with significant differences in lumber spine (mean difference = -0.03 g/cm2, P < 0.01 for both age groups) and pelvis BMDs (mean difference = -0.02 g/cm2, P < 0.01 for the adult age groups), after adjusting for various covariates.

CONCLUSIONS

This study confirmed that both adolescent and adult individuals seropositive for Hepatitis A antibodies had reduced BMD among both adolescents and adults, especially in the adult group. This finding suggests a possible link between Hepatitis A infection and risk of osteoporosis.

Three cases highlighting possible discrepancies in the interpretation of transgender DXA scores

For diagnosis of osteoporosis, a T-score of ≤-2.5 is recommended for all transgender and gender-diverse patients aged 50 years or older, regardless of hormonal status. This case series presents 3 transgender individuals younger than 50 years undergoing gender-affirming hormone therapy (GAHT) who had DXA scores suggestive of osteoporosis. We highlight possible discrepancies in DXA scan interpretations, especially in forearm bone mineral density measurements. We present the baseline (prior to beginning GAHT), 6-month, and 1-year follow-up DXA data along with pertinent labs to include 25-OH vitamin D, calcium, and alkaline phosphatase, for 2 transgender males (assigned female at birth) and 1 transgender female (assigned male at birth) undergoing GAHT who had low Z-scores and T-scores suggestive of osteoporosis. Multiple studies have analyzed the BMD data of individuals taking GAHT over time, which identify possible causes for low baseline Z-scores for transgender females, but less so for transgender males. Other than positional statements, guidelines remain unclear regarding diagnostic approaches to osteoporosis and low Z-scores in transgender individuals who are premenopausal or under 50 years of age. This case series addresses discrepancies in interpretation that may be encountered by clinicians with baseline and follow-up DXAs, especially involving the forearm, during the course of GAHT. This highlights the importance of establishing clearer guidelines for the diagnosis and treatment of osteoporosis and low BMD for chronological age in the transgender population.

Bone Health in the Transgender Population

» Transgender women are more susceptible to low bone mineral density (BMD) before initiating gender-affirming hormone therapy (GAHT), and while bone density initially improves with GAHT, it gradually declines while still remaining above baseline. Transgender women older than 50 years have a comparable fracture risk as age-matched cisgender women. Transgender men typically have normal or increased BMD before initiating and while receiving GAHT and are not at increased risk of fractures.» Transgender youth who receive puberty-blocking medications experience either no change or a slight decrease in BMD that returns to baseline after initiating GAHT.» It is important to abide by the International Society for Clinical Densitometry guidelines whenever ordering, performing, or reading a BMD scan for a gender-diverse patient.» There are no specific guidelines concerning vitamin D and calcium supplementation or the use of bisphosphonates in the transgender population, so the current recommendation is to abide by the guidelines for cisgender individuals.

Endocrine Health and Health Care Disparities in the Pediatric and Sexual and Gender Minority Populations: An Endocrine Society Scientific Statement

Endocrine care of pediatric and adult patients continues to be plagued by health and health care disparities that are perpetuated by the basic structures of our health systems and research modalities, as well as policies that impact access to care and social determinants of health. This scientific statement expands the Society's 2012 statement by focusing on endocrine disease disparities in the pediatric population and sexual and gender minority populations. These include pediatric and adult lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) persons. The writing group focused on highly prevalent conditions-growth disorders, puberty, metabolic bone disease, type 1 (T1D) and type 2 (T2D) diabetes mellitus, prediabetes, and obesity. Several important findings emerged. Compared with females and non-White children, non-Hispanic White males are more likely to come to medical attention for short stature. Racially and ethnically diverse populations and males are underrepresented in studies of pubertal development and attainment of peak bone mass, with current norms based on European populations. Like adults, racial and ethnic minority youth suffer a higher burden of disease from obesity, T1D and T2D, and have less access to diabetes treatment technologies and bariatric surgery. LGBTQIA youth and adults also face discrimination and multiple barriers to endocrine care due to pathologizing sexual orientation and gender identity, lack of culturally competent care providers, and policies. Multilevel interventions to address these disparities are required. Inclusion of racial, ethnic, and LGBTQIA populations in longitudinal life course studies is needed to assess growth, puberty, and attainment of peak bone mass. Growth and development charts may need to be adapted to non-European populations. In addition, extension of these studies will be required to understand the clinical and physiologic consequences of interventions to address abnormal development in these populations. Health policies should be recrafted to remove barriers in care for children with obesity and/or diabetes and for LGBTQIA children and adults to facilitate comprehensive access to care, therapeutics, and technological advances. Public health interventions encompassing collection of accurate demographic and social needs data, including the intersection of social determinants of health with health outcomes, and enactment of population health level interventions will be essential tools.

The Third Gender in a Third World Country: Major Concerns and the "AIIMS Initiative"

With a population dividend of around 1.3 billion, India is the largest democracy in the world that encompasses "unity in diversity". The kaleidoscope of the socio-cultural fabric comprises the transgender population too, which has a historical context dating back millennia and also plays a vital role as described in Hindu scriptures. The Indian transgender person's community shows a variety of gender identities and sexual orientations, which is unlikely from the West, forming a culturally unique gender group. In India, transgender persons were recognised as the 'third gender' in 2014. The third gender population of India is marginalised to a great extent in every sector. Often, transgender persons have been the subjects of sociology, psychology, and health issues. There was a dearth of data regarding their major health problems including bone health, which has not been reported in India and elsewhere before this study. Through a prospective cross-sectional study design, we aimed to determine the current health status of transgender persons with a special emphasis on bone health. Descriptive statistics were used for data analysis. The preliminary results of the study show poor bone health in the transgender population of India. The majority of transgender persons have low bone mineral density (BMD) at a much young age, even before the achievement of their peak bone mass. The health status of the transgender population in India is poor overall. Transgender persons have many impediments to optimal healthcare that requires holistic care. This study presents the current health challenges of the transgender population with a special emphasis on their bone health status as 'AIIMS initiative'. This study also shows transgender persons human rights needs to be explicitly discussed. The stakeholders of social policies require an urgent attention to unfold the major concerns encompassing transgender persons.

Providing gender-affirming care to transgender and gender-diverse individuals with and at risk for HIV

Transgender and gender-diverse populations have unique medical and psychosocial needs. It is important that clinicians address these needs with a gender-affirming approach in all aspects of health care for these populations. Given the significant burden of HIV experienced by transgender people, such approaches in providing HIV care and prevention are essential both to engage this population in care and to work toward ending the HIV epidemic. This review presents a framework for practitioners caring for transgender and gender-diverse individuals to deliver affirming, respectful health care in HIV treatment and prevention settings.

Unique considerations for the medical care of restrictive eating disorders in children and young adolescents

BACKGROUND

The medical complications of eating disorders are often approached through an age-neutral lens. However, children and young adolescents may have unique medical complications related to the energy needs and timing of growth and development. Providers caring for patients in this vulnerable age range should understand how to identify, approach, and manage these potential age-related complications.

REVIEW

Evidence continues to accumulate that increasingly younger patients are being diagnosed with eating disorders. These children and young adolescents have significant risk for unique and potentially irreversible medical complications. Without early identification and treatment, restrictive eating disorders may negatively impact linear growth, bone development and brain maturation in children and young adolescents. Additionally, due to the energy needs of growth and development, unique considerations exist for the use of acute medical stabilization and the identification of patients at risk for refeeding syndrome with initial nutritional rehabilitation. This review presents an approach to the evaluation and management of children and young adolescents with eating disorders.

CONCLUSION

Children and young adolescents with restrictive eating disorders may have unique medical complications related to the energy needs and timing of linear growth and pubertal development. Significant risk exists for irreversible medical complications of impaired growth, bone, and brain health. Increased awareness of the energy needs for growth and development may improve early recognition, appropriate intervention, and future outcomes for children and young adolescents with restrictive eating disorders.

Affirming Care for Transgender Patients

Gender identity is a deeply felt internal sense of self, which may correspond (cisgender) or not correspond (transgender) with the person's assigned sex at birth. Transgender, nonbinary, and gender diverse people may choose to affirm their gender in any number of ways including medical gender affirmation. This is a primer on the medical care of transgender individuals which covers an introduction to understanding a common language, history of transgender medical care, creating a welcoming environment, hormone therapy, surgical therapies, fertility considerations, and cancer screening in transgender people.

Hormonothérapie injectable et réduction des risques : pratiques, difficultés, santé des personnes trans en France

INTRODUCTION

Hormone therapy (HT) adherence practices among trans people are poorly studied. For a large proportion of these people, HT is administered parenterally. The unavailability of certain treatments in France, combined with poor institutional care, keeps injectors away from the health care system and encourages potentially risky injection practices. Following a significant increase in the number of trans people in its active list, the association Safe, coordinator of the remote harm reduction system in France, conducted a cross-sectional descriptive study from December 2020 to February 2021 using an anonymous self-administered online questionnaire.

PURPOSE OF RESEARCH

The objective is to better understand the profile of trans people who inject their HT and their injection practices.

RESULTS

We observed that a significant proportion of trans injectors do not benefit from professional support, either to obtain treatment or to carry out the injection. This situation can lead to certain misuses of medical supplies, such as needle sharing or reuse, which present significant health risks. This is especially true for injectors whose treatment is not legally available and who obtain it through parallel markets. This study also underlines the importance of self-support associations to accompany transition.

CONCLUSIONS

We therefore propose that a harm reduction policy adapted to the practices of trans people be implemented in order to better support this population and avoid the emergence of major health problems such as HIV infection.

Epilepsy Care in Transgender Patients

PURPOSE OF REVIEW

The goal of this review is to outline the main considerations when treating transgender patients with epilepsy. Points to be addressed include the gender affirming hormone therapy regimens and how they interact with anti-seizure medications and seizure control, as well as common co-morbidities in the transgender epilepsy population.

RECENT FINDINGS

Gender affirming hormone therapy (GAHT) may affect seizure control directly, due to proconvulsant or anticonvulsant properties. GAHT may interact with anti-seizure medications; most notably, estrogen will decrease serum concentration of lamotrigine. Enzyme-inducing anti-seizure medications may decrease hormone levels, potentially interfering with goals of GAHT. Transgender epilepsy patients are at risk for co-morbidities such as decreased bone mineral density and depression. There are minimal direct studies on treatment or outcomes in the transgender epilepsy population. Providers must be knowledgeable about the bi-directional interactions between gender affirming hormone therapy and anti-seizure medications, as well as direct hormonal influences on seizure control. Future research should directly evaluate outcomes in transgender epilepsy patients with regard to seizure control, success of hormone therapy, and management of co-morbidities, to further educate providers and patients how to best manage their healthcare.

Hormone Concentrations in Transgender Women Who Self-Prescribe Gender Affirming Hormone Therapy: A Retrospective Study

BACKGROUND

Self-prescribed gender-affirming hormone therapy (GAHT) is common practice among transgender women, especially in resource-limited countries, yet the effectiveness of each GAHT regimen to achieve female range sex hormone concentrations is not known.

AIM

To describe the use and sex hormone concentrations of various GAHT regimens among transgender women who self prescribe in Thailand.

METHODS

This was a retrospective study in a community-based setting. Five hundred and 27 records of transgender women taking GAHT who were receiving care at a community health center between January 1, 2018, and December 31, 2020 were included for the analysis.

MAIN OUTCOME MEASURES

Blood total testosterone and estradiol concentration after at least a 6-month period of GAHT.

RESULTS

Multiple GAHT regimens were identified including oral estradiol valerate (EV), transdermal 17β-estradiol gel, injectable EV with hydroxyprogesterone caproate, injectable estradiol benzoate with progesterone, oral EV with cyproterone acetate (CPA), and oral contraceptive pills (OCPs). The most common GAHT regimen used by 49.1% of the participants was OCPs that contained 0.035 mg of ethinyl estradiol and 2 mg of CPA. Only 25.2% of this group had female range testosterone concentrations (<50 ng/dL). Oral EV and CPA were used by 23.1% of the participants. Most of them used 12.5 mg of CPA and 47.7% of this group had female range testosterone concentrations. There was no statistical significance between mean testosterone concentrations in CPA 12.5 and 25 mg groups, (P = .086).

CLINICAL IMPLICATIONS

The inadequate sex hormone levels found in these commonly self-prescribed GAHT regimens provide information regarding the efficacy and safety of GAHT regimens for health care providers working with transgender women in a community-based setting.

STRENGTHS AND LIMITATIONS

This study reflected a real-world situation and provided hormonal profiles among transgender women taking self-prescribed GAHT. However, issues in recall, medical literacy, and adherence to the medication may limit the results.

CONCLUSION

Combined hormonal contraceptive pill was a commonly used GAHT regimen in Thai transgender women who self prescribe GAHT. However, this regimen was not effective to decrease testosterone concentrations to the recommended range of less than 50 ng/dL. Overall, self-prescription of GAHT does not appear to be effective in reaching target sex hormone concentrations. Including health care providers in the prescription and monitoring of GAHT may be a more effective approach in the delivery of GAHT. Salakphet T, Mattawanon N, Manojai N, et al.

Physical Therapist Management of Patients With Suspected or Confirmed Osteoporosis: A Clinical Practice Guideline From the Academy of Geriatric Physical Therapy

A clinical practice guideline on physical therapist management of patients with suspected or confirmed osteoporosis was developed by a volunteer guideline development group (GDG) that was appointed by the Academy of Geriatric Physical Therapy (APTA Geriatrics). The GDG consisted of an exercise physiologist and 6 physical therapists with clinical and methodological expertise. The guideline was based on a systematic review of existing clinical practice guidelines, followed by application of the ADAPTE methodological process described by Guidelines International Network for adapting guidelines for cultural and professional utility. The recommendations contained in this guideline are derived from the 2021 Scottish Intercollegiate Guideline Network (SIGN) document: Management of Osteoporosis and the Prevention of Fragility Fractures. These guidelines are intended to assist physical therapists practicing in the United States, and implementation in the context of the US health care system is discussed.

How Do Drugs Affect the Skeleton? Implications for Forensic Anthropology

Simple Summary

Forensic anthropologists analyze human remains to assist in the identification of the deceased, predominantly by assessing age-at-death, sex, stature, ancestry and any unique identifying features. Whilst methods have been established to create this biological profile of the skeleton, these may be influenced by a number of factors. This paper, for the first time, provides an overview from a reading of the clinical and pharmacological literature to explore whether the intake of drugs can affect the skeleton and whether these may have implications for forensic anthropology casework. In effect, drugs such as tobacco, heroin, and prescription medications can alter bone mineral density, can increase the risk of fractures, destroy bone and changes to the dentition. By considering how drugs can affect the skeleton, forensic anthropologists can be aware of this when attempting to identify the deceased.

Abstract

Forensic anthropologists rely on a number of parameters when analyzing human skeletal remains to assist in the identification of the deceased, predominantly age-at-death, sex, stature, ancestry or population affinity, and any unique identifying features. During the examination of human remains, it is important to be aware that the skeletal features considered when applying anthropological methods may be influenced and modified by a number of factors, and particular to this article, prescription drugs (including medical and non-medical use) and other commonly used drugs. In view of this, this paper aims to review the medical, clinical and pharmacological literature to enable an assessment of those drug groups that as side effects have the potential to have an adverse effect on the skeleton, and explore whether or not they can influence the estimation of age-at-death, sex and other indicators of the biological profile. Moreover, it may be that the observation of certain alterations or inconsistencies in the skeleton may relate to the use of drugs or medication, and this in turn may help narrow down the list of missing persons to which a set of human remains could belong. The information gathered from the clinical and medical literature has been extracted with a forensic anthropological perspective and provides an awareness on how several drugs, such as opioids, cocaine, corticosteroids, non-steroidal anti-inflammatory drugs, alcohol, tobacco and others have notable effects on bone. Through different mechanisms, drugs can alter bone mineral density, causing osteopenia, osteoporosis, increase the risk of fractures, osteonecrosis, and oral changes. Not much has been written on the influence of drugs on the skeleton from the forensic anthropological practitioner perspective; and this review, in spite of its limitations and the requirement of further research, aims to investigate the current knowledge of the possible effects of both prescription and recreational drugs on bones, contributing to providing a better awareness in forensic anthropological practice and assisting in the identification process of the deceased.

Inmune-mediated inflammatory rheumatic diseases in transgender people: A scoping review

BACKGROUND

In immune-mediated inflammatory rheumatic diseases (IMIRD), there are differences between cis-men and cis-women in epidemiology, clinical feature, therapeutic approach, treatment response, and prognosis. In transgender individuals, information concerning IMIRD is not substantial. The assessment of information concerning rheumatic diseases in transgenders is crucial because transgenders may undergo treatments with potential impacts on IMIRD. We aim to collect and discuss current knowledge on IMIRD in transgender individuals, determine the coverage of the literature, identify the knowledge gaps, and highlight opportunities for future research.

METHODS

We did a scoping review of publications collected through a systematic search of transgender patients with any IMIRD. Data sources were Medline, Embase, and Web of Knowledge. Synthesis of results and qualitative review of data information was collected in tables. A semi-quantification of the quality of the articles reporting clinical studies was performed.

RESULTS

There were 11 transwoman, and 3 transmen cases of systemic lupus erythematosus (5 cases), skin lupus erythematosus (2), systemic sclerosis (4), anti-synthetase syndrome (1), rheumatoid arthritis (1) and ankylosing spondylitis (1). Eleven were de novo cases and three had prior history of IMIRD and developed a comorbidity after starting hormone replacement therapy. The clinical expression of the disease was variable. Two transwomen and one transman developed thrombotic events. The lupus skin lesions in one transman improved following testosterone treatment. No clinical studies were identified. Quality of publications was disparate.

CONCLUSION

Although the number of cases is small, most cases of IMIRD occur in transwomen. The absence of solid data warrants caution in establishing recommendations regarding hormone replacement therapy in transgenders with IMIRD. There is an essential need for the consideration of cisgender and transgender particularities in future research on IMIRD.

Rethinking of osteoporosis through a sex- and gender-informed approach in the COVID-19 era

Standards and models of reference for osteoporosis (OP) have been developed for female individuals as they are more likely to be affected by the disease. Nonetheless, OP is also responsible for one-third of hip fractures in male individuals suggesting that a sexblinded approach to OP may lead to miss opportunities for equity in bone health. OPrelated fractures, especially hip fractures, are a matter of immediate concern as they are associated with limited mobility, chronic disability, loss of independence, and reduced quality of life in both sexes. When it comes to sociocultural gender, the effect of gender domains (i.e., identity, roles, relations, and institutionalized gender) on development and management of OP is largely overlooked despite risk factors or protective conditions are gendered. Clinical trials testing the efficacy and safety of anti-OP drugs as well as non-pharmacological interventions have been conducted mainly in female participants, limiting the generalizability of the findings. The present narrative review deals with the sex and gender-based challenges and drawbacks in OP knowledge and translation to clinical practice, also considering the impact of coronavirus disease 2019 pandemic.

Gender-Affirming Hormone Therapy and Bone Health: Do Different Regimens Influence Outcomes in Transgender Adults? A Narrative Review and Call for Future Studies

BACKGROUND

Gender-affirming hormone therapy (GAHT) influences bone health in transgender individuals. Several hormone preparations and administration routes are available for GAHT, but no studies have compared clinical and laboratory bone health measures across different GAHT regimens.

CONTENT

We searched PubMed (MEDLINE), Embase, and Google Scholar for studies measuring bone turnover markers and bone mineral density before and during GAHT in transgender adults. We summarized bone health data by hormone type and administration route (estrogen or testosterone; oral, transdermal/percutaneous, intramuscular). Among trans women, we also examined outcomes among regimens containing different adjunctive agents (antiandrogens or gonadotropin-releasing hormone analogs).

SUMMARY

Most hormone preparations maintained or increased areal bone mineral density among trans adults taking GAHT for at least 12 months from baseline. Different bone turnover markers were measured across studies, and we were unable to compare or comment on the direct influence of selected hormone preparations on these clinical laboratory measures. Larger and uniformed studies are needed to measure volumetric bone mineral density and biomarkers of bone metabolism in trans adults taking standardized GAHT regimens.

Medical transition for gender diverse patients

Purpose of review

The purpose of this review is to provide an up-to-date overview of gender-affirming hormone therapy, including the various hormone regimens available, the efficacy and potential risks of these treatments, and considerations for surveillance and long-term care.

Recent findings

Recent studies reaffirm that hormone therapy has positive physical and psychological effects for many transgender individuals. The overall risks of treatment are low. Transgender women may have an increased risk of venous thromboembolism and breast cancer based on recent cohort studies, but these findings have yet to be confirmed with randomized controlled trials. Important long-term considerations include metabolic, cardiovascular, and skeletal health.

Summary

High-quality, long-term studies on the effectiveness and safety of various gender-affirming hormone treatment regimens are lacking, but the currently available evidence suggests that it is overall safe and effective with appropriate oversight.

Sexual orientation-based disparities in bone health: Evidence of reduced bone mineral density and mineral content among sexual minority men but not women in multiple NHANES waves

INTRODUCTION

Sexual minority (SM) people experience significant stress associated with stigma, contributing to a higher rate of adverse health outcomes. Several known factors (eg, smoking) elevate risk of poor bone health, but to date little research has examined disparities in bone health among SM people. To address this, we analyzed sexual orientation differences in an available bone mineral density (BMD) cross-sectional dataset assessed via dual X-ray absorptiometry.

METHODS

We combined the 2007 to 2008, 2009 to 2010, and 2013 to 2014 cycles of US National Health and Nutrition Examination Survey to examine sexual orientation-based differences in z-scored BMD in the proximal femur (greater trochanter and intertrochanter locations), bone mineral content (BMC) in the femur and spine, and osteoporosis risk among Lesbian/Gay (n = 53), Bisexual (n = 97), Same-Sex Experienced (n = 103), and Heterosexual (n = 2990) adults.

RESULTS

Sexual orientation-based disparities in bone mass were observed across all anatomical sites. This effect was due to differences between heterosexual and gay men and persisted in linear regressions after adjusting for risk factors. We found differences in femoral and femoral neck BMC in heterosexual and gay men (P = .02) and in femoral, femoral neck and spinal BMC between heterosexual and bisexual women (P = .05). Sexual orientation remained significant in BMC regressions.

CONCLUSION

Our findings suggest that SM men but not women are at greater risk for poor bone health relative to heterosexuals and this disparity is independent of the lifestyle and psychosocial risks included in our models.

Bone Health and Osteoporosis Prevention and Treatment

Postmenopausal osteoporosis is a common condition and is associated with increased risk of fracture, including hip and vertebral fractures that in turn can have devastating consequences on morbidity and mortality. In this article, we review the pathogenesis and diagnostic approach to postmenopausal osteoporosis. We review available nonpharmacologic and pharmacologic therapies and we discuss their clinical efficacy and complications, with a detailed discussion of atypical femur fractures and osteonecrosis of the jaw.

Transwomen and bone mineral density: a cross-sectional study in Brazilian population

OBJECTIVES

Transgender individuals submitted to hormone or surgical treatment may have alterations in their bone metabolism as these elements are important players in bone remodeling. We aimed to study bone mineral density (BMD) and body composition in transwomen undergoing cross-sex hormonal treatment (CSHT) from Brazil for over 3 years, comparing them with female and male controls.

METHODS

93 individuals (31 transwomen, 31 females and 31 males paired for age and body mass index) were studied for bone mass, and body composition by densitometry (by DXA). Epidemiological and clinical data were collected through direct questioning.

RESULTS

Low bone mass (T score ≤2) was found in 12.9% of transwomen; in 3.2% of females and 3.3% of males. Transwomen individuals had lower spine Z score (0.26 ± 1.42 vs 0.50 ± 1.19) and femur Z score (-0.41 ± 0.95 vs 0.29 ± 1.04) than females. They had lower total femur Z score than males (-0.41 ± 0.95 vs 0.20 ± 0.83). Lean mass values correlated positively with total femur BMD (ρ = 0.40; 95% confidence interval = 0.009-0.68; p = 0.04) and BMD in femoral neck (ρ = 0.48; 95% confidence interval = 0.11-0.74; p = 0.01) but neither the type of therapy received nor the time that they were used, impacted bone mass.

CONCLUSION

Low BMD is found frequently in transwomen and it is correlated with lean body mass.

ADVANCES IN KNOWLEDGE

There are few studies of the effects of hormone therapy on the bones and muscles of transwomen. This study demonstrated that significant changes occur, and that the population studied needs greater care in musculoskeletal health.

Trans-specific Geriatric Health Assessment (TGHA): An inclusive clinical guideline for the geriatric transgender patient in a primary care setting

There is a growing concern in the field of geriatric medicine that transgender health is often overlooked and under-reported. Not only does this impact the health and safety of the aging transgender community, but it also often influences the ability of physicians to provide high-quality evidence-based care. This article reviews the current knowledge base for geriatric transgender health and aims to organize evidence-based clinical recommendations for the primary care provider. Our proposed guideline, the Trans-specific Geriatric Health Assessment (TGHA), highlights areas of current clinical practice that do not address the geriatric transgender experience and modifies them to include trans-specific clinical recommendations found in the literature. The TGHA emphasizes topics such as cognitive function, vision and hearing, gait and stability, nutrition, sleep, functional/social status, urogenital health, psychiatric health, hormone replacement therapy, cancer screening, disease prevention and advanced care planning. Our review also addresses the limitations of certain clinical topics and where there is significant need for supportive research.

Systematic Review of the Long-Term Effects of Transgender Hormone Therapy on Bone Markers and Bone Mineral Density and Their Potential Effects in Implant Therapy

This study seeks to evaluate the long-term effects of pharmacologic therapy on the bone markers and bone mineral density of transgender patients and to provide a basis for understanding its potential implications on therapies involving implant procedures. Following the referred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and well-defined PICOT (Problem/Patient/Population, Intervention, Comparison, Outcome, Time) questionnaires, a literature search was completed for articles in English language, with more than a 3 year follow-up reporting the long-term effects of the cross-sex pharmacotherapy on the bones of adult transgender patients. Transgender demographics, time under treatment, and treatment received were recorded. In addition, bone marker levels (calcium, phosphate, alkaline phosphatase, and osteocalcin), bone mineral density (BMD), and bone turnover markers (Serum Procollagen type I N-Terminal pro-peptide (PINP), and Serum Collagen type I crosslinked C-telopeptide (CTX)) before and after the treatment were also recorded. The considerable variability between studies did not allow a meta-analysis. All the studies were completed in European countries. Transwomen (921 men to female) were more frequent than transmen (719 female to male). Transwomen's treatments were based in antiandrogens, estrogens, new drugs, and sex reassignment surgery, meanwhile transmen's surgeries were based in the administration of several forms of testosterone and sex reassignment. Calcium, phosphate, alkaline phosphatase, and osteocalcin levels remained stable. PINP increased in transwomen and transmen meanwhile, CTX showed contradictory values in transwomen and transmen. Finally, reduced BMD was observed in transwomen patients receiving long-term cross-sex pharmacotherapy. Considering the limitations of this systematic review, it was concluded that long-term cross-sex pharmacotherapy for transwomen and transmen transgender patients does not alter the calcium, phosphate, alkaline phosphatase, and osteocalcin levels, and will slightly increase the bone formation in both transwomen and transmen patients. Furthermore, long-term pharmacotherapy reduces the BMD in transwomen patients.
