RESUMO

Purpose: Feminizing hormone therapy (FHT) is used by many transgender women as a pharmacological method to mitigate gender dysphoria. However, information on hormone concentrations among those who use FHT is lacking. We aimed to determine the proportion of Thai transgender women who were using FHT who had hormone concentrations within target ranges in a real-world clinic setting. Methods: Transgender women who attended Tangerine Clinic in Bangkok, Thailand, reported current use of FHT at clinic entry, and tested for both blood estradiol (E2) and total testosterone (TT) concentrations were included in the analysis. Hormone target concentrations were defined as 100-200 pg/mL for E2 and <50 ng/dL for TT. Results: Of 1534 transgender women included, 2.5% had undergone orchiectomy, and 524 (34.2%) had any hormones within target concentrations. Median (interquartile range) E2 and TT concentrations at baseline were 29 (14.3-45.3) pg/mL and 298.5 (22-646) ng/dL, respectively. Among those who had any hormones within target concentrations, 28 (1.8%), 11 (0.7%), and 485 (31.6%) had both hormones, only E2, and only TT within target concentrations, respectively. Among 1010 (65.8%) transgender women who had neither hormone within target concentrations, 989 (64.5%) and 21 (1.4%) had suboptimal and supraphysiological E2 concentrations, respectively. Among those who came to at least one follow-up visit (n=302), 165 (54.6%) transgender women managed to achieve or maintain either hormone within target concentrations. Conclusion: One-third of Thai transgender women who were using FHT had any hormones within target concentrations at baseline in this real-world setting study. Most transgender women who had neither hormone within target concentrations had suboptimal rather than supraphysiological E2 concentrations. More than half managed to achieve or maintain at least one hormone concentration within target concentrations at follow-up visits, suggesting a positive effect from attending a trans-led, integrated gender-affirming care and sexual health service.

RESUMO

INTRODUCTION: Provider-collected swabs are an unappealing procedure for many transgender women and may have led to suboptimal rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing. Self-collection for CT/NG testing is recommended for men who have sex with men. However, the information on acceptability and clinical performance to support a recommendation for transgender women is lacking. We aimed to determine the acceptability and satisfaction towards self-collection for CT/NG testing among Thai transgender women. METHODS: Thai transgender women who attended Tangerine Clinic (a transgender-led, integrated, gender-affirming care and sexual health services clinic in Bangkok, Thailand) between May and July 2020 and had condomless sexual intercourse within the past six months were offered to collect urine and perform self-swabs of pharyngeal, rectal, and if applicable, neovaginal compartments for pooled nucleic acid amplification testing for CT/NG infections. Participants received a diagram, video and oral instructions about how to perform self-collection procedure. Those who accepted self-collection were also offered to receive provider collection to evaluate the performance between the two methods. Self-administered questionnaires were used to assess satisfaction. RESULTS: Among 216 transgender women enrolled, 142 (65.7%) accepted self-collection. All who accepted had pharyngeal, rectal and urine samples collected. Of 31 transgender women who had undergone genital surgery, 28 (90.3%) accepted neovaginal self-swab. The acceptance rate increased from 46.2% in May to 84.5% in July 2020. One participant had an invalid result. All transgender women who accepted self-collection could perform it without assistance, and 82.8% were highly satisfied with the method. None reported dissatisfaction. Due to the COVID-19 pandemic, provider collection services were discontinued early, and only eight transgender women were able to perform both methods for performance evaluation. The performance agreement was 100%. CONCLUSIONS: Thai transgender women had high acceptability and satisfaction towards self-collection for CT/NG testing. The performance was promising compared to provider collection. Our results support the implementation of self-collection to the sexually transmitted infection services, particularly during the COVID-19 pandemic where physical distancing is the new normal. A larger study is warranted to determine the performance of self-collection for CT/NG testing in each anatomical compartment and confirm the performance between self-collection and provider collection.

RESUMO

BACKGROUND: Drug-drug interactions between feminizing hormone therapy (FHT) and antiretroviral therapy (ART) are a major concern among transgender women (TGW), which may lead to suboptimal ART adherence and inappropriate FHT dosage. To evaluate potential drug-drug interactions between FHT and ART, we performed intensive measurements of the pharmacokinetic (PK) parameters of blood tenofovir (TFV), efavirenz (EFV), and estradiol (E2). METHODS: Twenty TGW with newly diagnosed human immunodeficiency virus (HIV) infection were enrolled. FHT (E2 valerate 2 mg/d and cyproterone acetate 25 mg/d) was prescribed at baseline until week 5 and restarted at week 8. ART (TFV disoproxil fumarate/emtricitabine/EFV at 300/200/600 mg) was initiated at week 3. The E2 PK parameters were measured intensively at weeks 3 (without ART) and 5 (with ART), and TFV and EFV PK parameters were measured intensively at weeks 5 (with FHT) and 8 (without FHT). RESULTS: The median (interquartile range) age and body mass index were 25.5 (22.5-31.0) years and 20.6 (19.3-23.1) kg/m2, respectively. The differences in geometric mean ratios between weeks 3 and 5 were as follows for E2 area under the curve, maximum concentration, and concentration at 24 hours (C24), respectively: 0.72 (90% confidence interval, .64-.81; P < .001), 0.81 (.72-.92; P = .006), and 0.64 (.50-.83; P = .004). The differences in geometric mean ratios between weeks 5 and 8 were as follows for TFV AUC, TFV C24, and EFV C24: 0.86 (90% confidence interval, .80-.93; P = .002), 0.83 (.75-.93; P = .006), and 0.91 (.85-.97; P = .02). CONCLUSIONS: Among HIV-positive TGW, E2 PK parameters were significantly lower in the presence of TFV disoproxil fumarate/emtricitabine/EFV, and some TFV and EFV PK parameters were lower in the presence of FHT. Further studies should determine whether these reductions are clinically significant and whether they occur with other FHT or ART regimens.
