Integration of Gender-Affirming Primary Care and Peer Navigation With HIV Prevention and Treatment Services to Improve the Health of Transgender Women: Protocol for a Prospective Longitudinal Cohort Study.

ABSTRACT:

Background

Public health strategies are urgently needed to improve HIV disparities among transgender women, including holistic intervention approaches that address those health needs prioritized by the community. Hormone therapy is the primary method by which many transgender women medically achieve gender affirmation. Peer navigation has been shown to be effective to engage and retain underserved populations living with HIV in stable primary medical care.

Objective

This study aims to assess the feasibility and acceptability of an integrated innovative HIV service delivery model designed to improve HIV prevention and care by combining gender-affirming primary care and peer navigation with HIV prevention and treatment services.

Methods

A 12-month, nonrandomized, single-arm cohort study was implemented in Lima, Peru, among adult individuals, assigned a male sex at birth, who identified themselves as transgender women, regardless of initiation or completion of medical gender affirmation, and who were unaware of their HIV serostatus or were living with HIV but not engaged in HIV treatment. HIV-negative participants received quarterly HIV testing and were offered to initiate pre-exposure prophylaxis. HIV-positive participants were offered to initiate antiretroviral treatment and underwent quarterly plasma HIV-1 RNA and peripheral CD4+ lymphocyte cell count monitoring. All participants received feminizing hormone therapy and adherence counseling and education on their use. Peer health navigation facilitated retention in care by visiting participants at home, work, or socialization venues, or by contacting them by social media and phone.

Results

Patient recruitment started in October 2016 and finished in March 2017. The cohort ended follow-up on March 2018. Data analysis is currently underway.

Conclusions

Innovative and culturally sensitive strategies to improve access to HIV prevention and treatment services for transgender women are vital to curb the burden of HIV epidemic for this key population. Findings of this intervention will inform future policies and research, including evaluation of its efficacy in a randomized controlled trial.

Project description:BackgroundThe effect of gender affirming hormone therapy (GAHT) on clinical laboratory parameters, including levels of liver enzymes alanine aminotransferase (ALT) and aspartate transaminase (AST), is an area of uncertainty in transgender health.AimWe sought to estimate the distribution parameters of liver enzyme levels among transmasculine (TM) and transfeminine (TF) persons receiving GAHT relative to the corresponding measures in cisgender reference groups, and to evaluate longitudinal changes in these laboratory measures following GAHT initiation.MethodsThe data for this longitudinal study included 624 TF and 438 transmasculine (TM) people as well as 4,090 cisgender males and 4,797 cisgender females enrolled in 3 integrated health systems. Time under observation was divided into 2 intervals: from the first blood test to the date of the first filled GAHT prescription and from GAHT initiation to the most recent ALT or AST measurement. Linear mixed models were used to compare changes in log-transformed ALT and AST values among transgender cohort members before and after GAHT initiation, and relative to the reference groups. The results were expressed as relative differences (in %) and the ratios of these differences (ratios-of-ratios) along with the 95% confidence intervals (CIs).OutcomesChanges in ALT and AST levels among transgender people over time and relative to the corresponding changes in cisgender referents.ResultsAmong TM study participants, the post GAHT ratios-of-ratios for AST were 1.61 (95% CI: 1.13, 2.31) and 1.57 (95% CI: 1.06, 2.31) relative to cisgender males and females respectively. For ALT, the corresponding comparisons yielded the ratios-of-ratios (95% CIs) of 2.06 (1.67, 2.54) and 1.90 (1.50, 2.40). No statistically significant changes were observed among TF participants. Other factors associated with higher liver enzyme levels included alcohol use/abuse and obesity.Clinical implicationsTM persons may experience modest increases in ALT and AST concentrations following testosterone initiation; however, clinical significance of the observed association remains unclear and requires further investigation. By contrast, feminizing GAHT is unlikely to induce appreciable changes in liver enzyme levels.Strength and limitationsThe strengths of this study are the longitudinal design and the ability to assemble an unselected cohort nested within large health systems. The main limitations include the lack of information on hormone levels and the inability to take into account GAHT doses and routes of administration.ConclusionThe influence of long-term GAHT on ALT and AST levels appears modest and not likely to reflect clinically meaningful changes in liver function.

Project description:ImportanceIn the US, transgender, nonbinary, and gender diverse (TGD) adults have high rates of depression. Gender-affirming hormone therapy (GAHT) is associated with improved mental health outcomes, yet existing US studies have short follow ups and lack sample diversity.ObjectiveTo evaluate the use of GAHT delivered in primary care as an intervention for moderate-to-severe depressive symptoms in diverse TGD adult patients.Design, setting, and participantsLEGACY was an observational cohort study conducted in federally qualified community health centers in Boston and New York that followed up TGD patients (N = 3592) from calendar years 2016 to 2019 (48 months). Participants included individuals aged 18 years or older, gender identity different from sex at birth, a past 12-month medical visit, and signed patient consent form in the electronic health record (EHR).ExposuresPrescriptions for GAHT obtained from EHR data, using the date of the first and last GAHT prescription in each calendar year of observation (GAHT within the year vs no GAHT during the year).Main outcomes and measuresA binary outcome of patient-reported moderate-to-severe depressive symptoms was obtained using the validated Patient-Health Questionnaire (PHQ), scoring 10 or greater on the PHQ-9 or scoring 3 or greater on the PHQ-2. Following multiple imputation, generalized estimating equations (GEE) longitudinally modeled GAHT and moderate-to-severe depressive symptoms (n = 20 320 observations) and adjusted for age, gender identity, race and ethnicity, health insurance, federal poverty level, HIV serostatus, number of cohort years, and clinical site.ResultsThe median age of the 3592 patients was 28 (IQR, 24-36) years. Race and ethnicity was diverse (1.3% Asian/Pacific Islander, 11.7% Black, 16.1% Hispanic/Latinx, 63.1% White, 6.8% multiracial, and 1.4% other). In addition, 18.9% were nonbinary, 52.1% lived below the federal poverty level, 34.2% were publicly insured, 4.1% were uninsured, and 5.1% were living with HIV. At baseline, 84.5% of the individuals were prescribed GAHT and 15.3% reported moderate-to-severe depressive symptoms. Patients prescribed GAHT had a statistically significantly lower risk of moderate-to-severe depressive symptoms over follow-up compared with those not prescribed GAHT (adjusted risk ratio, 0.85; 95% CI, 0.75-0.98).Conclusions and relevanceIn this longitudinal observational cohort study, GAHT was associated with lower rates of moderate-to-severe depressive symptoms, highlighting the importance of gender-affirming primary care models for TGD patients.

Project description:ImportanceGender-affirming hormone treatment (GAHT) is a common therapy for transgender individuals to reduce gender dysphoria and improve quality of life. Clarifying the long-term effects of GAHT remains a priority in transgender health research.ObjectiveTo explore whether sex hormones (estradiol and testosterone) are associated with the development of metabolic syndrome in transgender veterans compared with cisgender veterans.Design, setting, and participantsThis retrospective, longitudinal cohort study used International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis codes for gender dysphoria from the Veterans Health Administration national database to identify transfeminine and transmasculine veterans receiving documented feminizing (estradiol) or masculinizing (testosterone) treatment from January 1, 2006, to December 31, 2019, and for whom the GAHT initiation date and metabolic syndrome component-related data were available. Transgender veterans were matched to cisgender referents.ExposureGender-affirming hormone treatment.Main outcomes and measuresMetabolic syndrome z-scores were calculated based on body mass index, systolic blood pressure, and levels of high-density lipoprotein cholesterol, triglycerides, and blood glucose. Changes in mean z-scores were compared among the transgender and cisgender groups before and after the index date (corresponding to GAHT initiation) using a repeated-measures analysis of variance model.ResultsThe cohort included 1290 participants: 645 transgender (494 [38.3%] transfeminine, 151 [11.7%] transmasculine) and 645 cisgender (280 [21.7%] female, 365 [28.3%] male). Mean (SD) age at the index date was 41.3 (13.2) years. Metabolic syndrome z-scores changed significantly over time and differed significantly across groups. Overall, transmasculine veterans had the greatest percentage increase in mean (SEM) z-scores after vs before the index date (298.0% [57.0%]; P < .001), followed by cisgender females (108.3% [27.5%]; P < .001), cisgender males (49.3% [27.5%]; P = .02), and transfeminine persons (3.0% [10.7%]; P = .77).Conclusions and relevanceIn this cohort study, in both cisgender and transgender veterans, estradiol was associated with reduced metabolic syndrome risk, whereas testosterone was associated with increased risk. However, transmasculine individuals had the greatest risk and transfeminine individuals had the lowest risk of metabolic syndrome associated with these hormones. This is relevant for the management of metabolic syndrome risk factors in cisgender and transgender individuals and to potentially predict the risk of atherosclerotic cardiovascular disease, type 2 diabetes, systolic hypertension, insulin resistance, and nonalcoholic fatty liver disease.
