RESUMO

PURPOSE: While it is common for menstrual cycles to cease within the initial 6 months of treatment, there are instances where some transgender men may not experience this cessation. We analyzed transgender men undergoing gender-affirming hormone therapy (GAHT) with testosterone who experienced breakthrough bleeding in order to identify the factors associated with this condition. METHODS: In this case-control study, 24 transgender men in the case group and 48 in the control group were assessed for clinical, sociodemographic, hormonal, and body composition variables using dual-energy X-ray absorptiometry. All participants had been on GATH for at least 6 months. RESULTS: A few transgender men experienced persistent breakthrough bleeding, which was associated with decreased testosterone levels and free androgen index (FAI) compared with controls (p = 0.002 and p = 0.008, respectively). Among individuals with breakthrough bleeding, 50% had testosterone levels below the lowest tertile calculated for the sample, compared with 18.8% on controls (p = 0.007). After therapy adjustment, testosterone levels increased compared with the values obtained in the initial bleeding episode (p = 0.031). Eight transgender men required the addition of an oral progestogen to achieve amenorrhea, and these individuals had higher BMI than those in whom the adjustment of the parenteral testosterone dose was adequate (p = 0.026). A univariate prevalence ratio analysis revealed a negative association of persistent bleeding with testosterone levels (p = 0.028) and FAI levels (p = 0.019). CONCLUSION: Higher BMI and lower levels of testosterone and FAI were the main factors associated with breakthrough bleeding in transgender men.

RESUMO

A trans-male (TM) is a biologically female person with male gender identity who wishes to acquire male sexual characteristics and fulfil a male social role. To achieve that purpose, both cross-hormonal therapy (CHT) and surgical phalloplasty can be used. We evaluated the short term (12 months) safety profile of CHT using different forms of testosterone available for prescription in Argentina. In this retrospective study, we analyzed the medical history of 30 trans-male patients fitting the inclusion criteria. The mean age of the population was 27 years. The mean basal serum level of testosterone was 0.43 ng/ml, which increased to 6.36 ng/ml (male hormonal levels). The hematocrit increased from a baseline of 40.0 to 45.2% (p < 0.01) and hemoglobin increased from 13.6 to 15.2 g/dl (p < 0.01). Total cholesterol remained stable with values of 175 and 185 mg/dl (p = 0.81). There were no significant changes in serum triglycerides: 88.3 and 102 mg/dl (p = 0.08). LDL increased in the first 6 to 12 months of CHT from 101.2 to 112.5 mg/dl (p = 0.17). At 12 months HDL levels increased from 50.1 to 52 mg/dl (p < 0.01). Hepatic enzymes remained stable. There is no available data regarding safety of testosterone use in TM in our country. In no case did we need to suspend the medication due to unwanted effects.

RESUMO

Se denomina trans-varón (TV) a una persona de sexo biológico femenino con identidad de género masculino. Para adquirir caracteres sexuales y expresar un rol social semejante podría utilizarse: terapia hormonal cruzada (THC) y/o genitoplastia masculinizante. Se evaluó el perfil de seguridad a corto plazo (primer año) de la THC con las distintas formas farmacéuticas de testosterona disponibles en nuestro país. El estudio se realizó de manera retrospectiva, analizando las historias clínicas de 30 pacientes trans-varón que cumplían con los requisitos para ser incluidos. La edad media de la población fue de 27 años. La media basal de testosterona fue de 0.43 ng/ml, que luego aumentó a 6.36 ng/ml (valores normales para sexo masculino). El hematocrito incrementó de su valor basal 40.0 a 45.2% (p < 0.01) mientras la Hb de 13.6 a 15.2 g/dl (p < 0.01). El colesterol total se mantuvo estable con valores de 175 y 185 mg/dl (p = 0.81). No hubo cambios significativos en triglicéridos: 88.3 y 102 mg/dl (p = 0.08). El colesterol LDL incrementó en los primeros 6 a 12 meses de THC de 101.2 a 112.5 mg/dl (p = 0.17). A los 12 meses los niveles de colesterol HDL aumentaron de 50.1 a 52.0 mg/ dl (p < 0.01). Las enzimas hepáticas se mantuvieron estables. No existen datos en nuestro país sobre seguridad de la testosterona en TV. No tuvimos necesidad de suspender la medicación por efectos no deseados en los parámetros estudiados.

RESUMO

INTRODUCTION:: Transsexualism (ICD-10) is a condition characterized by a strong and persistent dissociation with one's assigned gender. Sex reassignment surgery (SRS) and hormone therapy provide a means of allowing transsexual individuals to feel more congruent with their gender and have played a major role in treatment over the past 70 years. Brain-derived neurotrophic factor (BDNF) appears to play a key role in recovery from acute surgical trauma and environmentally mediated vulnerability to psychopathology. We hypothesize that BDNF may be a biomarker of alleviation of gender incongruence suffering. OBJECTIVES:: To measure preoperative and postoperative serum BDNF levels in transsexual individuals as a biomarker of alleviation of stress related to gender incongruence after SRS. METHODS:: Thirty-two male-to-female transsexual people who underwent both surgery and hormonal treatment were selected from our initial sample. BDNF serum levels were assessed before and after SRS with sandwich enzyme linked immunosorbent assay (ELISA). The time elapsed between the pre-SRS and post-SRS blood collections was also measured. RESULTS:: No significant difference was found in pre-SRS or post-SRS BDNF levels or with relation to the time elapsed after SRS when BDNF levels were measured. CONCLUSION:: Alleviation of the suffering related to gender incongruence after SRS cannot be assessed by BDNF alone. Surgical solutions may not provide a quick fix for psychological distress associated with transsexualism and SRS may serve as one step toward, rather than as the conclusion of, construction of a person's gender identity.

Resumo Introdução: O transexualismo (CID-10) é uma condição caracterizada por forte e persistente dissociação com o gênero atribuído. A cirurgia de redesignação sexual (CRS) e a terapia hormonal (TH) permitem que indivíduos transexuais se sintam mais congruentes com seu gênero e, por isso, têm desempenhado papel importante nos últimos 70 anos. O fator neurotrófico derivado do cérebro (BDNF) parece desempenhar um papel fundamental na recuperação do trauma cirúrgico agudo e vulnerabilidade ambiental à psicopatologia. Nós hipotetizamos que o BDNF pode ser um biomarcador de alívio do sofrimento de incongruência de gênero pós-CRS. Objetivos: Mensurar os níveis séricos de BDNF no pré e pós-operatório em indivíduos transexuais como biomarcador de alívio de estresse relacionado à incongruência de gênero após a CRS. Métodos: Trinta e duas pessoas transexuais masculino para feminino submetidas a cirurgia e tratamento hormonal foram selecionadas de nossa amostra inicial. O nível sérico de BDNF foi avaliado antes e depois da CRS pela técnica ELISA. O tempo decorrido entre as coletas de sangue pré e pós-CRS foi medido. Resultados: Não houve diferença significativa nos níveis de BDNF pré e pós-CRS ou em relação ao tempo decorrido entre a CRS e a coleta. Conclusão: O alívio do sofrimento relacionado à incongruência de gênero pós-CRS não pode ser avaliado apenas pelo BDNF. Soluções cirúrgicas podem não fornecer uma solução rápida para o sofrimento associado ao transexualismo, e a CRS pode servir como um passo em direção à, em vez de conclusão da, construção da identidade de gênero de uma pessoa.

RESUMO

Serum BDNF levels are significantly decreased in transsexual Brazilian women when compared to cis-sexual men. Since transsexual men are also exposed to chronic social stress and have a high prevalence of associated psychopathologies, it is plausible to inquire if BDNF serum levels are altered in transsexual men as well. Therefore, our objective was to evaluate differences in BDNF serum level of transsexual men when compared to cis-sexual men and women. Our sample comprises 27 transsexual men, 31 cis-sexual women and 30 cis-sexual men recruited between 2011 and 2015. We observed that BDNF serum concentration is decreased in transsexual men comparing to cis-sexual men and women. Cross-sex hormone treatment, chronic social stress or long-term gender dysphoria (GD) could explain the variation found in BDNF serum levels.

RESUMO

Gender Identity Disorder (GID) is characterized by a strong and persistent cross-gender identification that affects different aspects of behavior. Brain-derived neurotrophic factor (BDNF) plays a critical role in neurodevelopment and neuroplasticity. Altered BDNF-signaling is thought to contribute to the pathogenesis of psychiatric disordersand is related to traumatic life events. To examine serum BDNF levels, we compared one group of DSM-IV GID patients (n = 45) and one healthy control group (n = 66). Serum BDNF levels were significantly decreased in GID patients (p = 0.013). This data support the hypothesis that the reduction found in serum BDNF levels in GID patients may be related to the psychological abuse that transsexuals are exposed during their life.
