    醋酸环丙孕酮(CPA)和螺内酯(SPL)是变性女性性别确认激素治疗(GAHT)中不同的抗雄激素药物。很少有研究评估他们的功效和用户满意度,尤其是东亚人。本研究旨在评估中国跨性别女性的这些方面。
    回顾性收集2012-2021年在北京大学第三医院就诊的变性人女性资料。从639名变性女性中,其中151个(80个使用CPA,71个使用SPL,16至40岁)在稳定的GAHT≥6个月下进行登记。评估总睾酮水平和基于视觉模拟量表(VAS)的满意度评分。
    CPA组和SPL组之间的年龄没有差异(中位数[IQR],22[20-24]年和23[20-26]年,分别)。CPA组的GAHT持续时间长于SPL组(18[10-32]个月vs.12[8-21]个月,p=0.009)。CPA治疗(25mg/d)的总睾丸激素水平显着低于SPL治疗(100mg/d)(中位数[IQR]:0.7[0.7-2.1]nmol/Lvs.13.0[6.0-17.8]nmol/L,p<0.001)。CPA组总睾酮水平达到推荐范围的比例明显高于SPL组(75.0%vs.11.3%,p<0.001)。CPA组基于VAS的勃起满意度评分下降,身材女性化高于SPL组,在调整年龄后保持不变,治疗持续时间,雌二醇剂量,和合并症精神障碍(p<0.05)。CPA组催乳素水平高于SPL组(18.9[11.8-28.1]ng/mlvs.11.8[7.9-18.4]ng/ml,p<0.001)。两组均未发生严重的安全事件。
    在中国变性女性中,在降低睾酮水平方面,CPA比SPL更有效。此外,与SPL相比,VAS得分表明对使用CPA的勃起减少和数字女性化的满意度更高。
    UNASSIGNED: Cyproterone acetate (CPA) and spironolactone (SPL) are different antiandrogens in gender-affirming hormone therapy (GAHT) for transgender women. Few studies have evaluated their efficacy and user satisfaction, especially among East Asians. This study aimed to evaluate these aspects in Chinese transgender women.
    UNASSIGNED: Data were collected retrospectively from transgender women visiting the Peking University Third Hospital from 2012 to 2021. From 639 people identified as transgender women, 151 of them (80 using CPA and 71 using SPL, 16 to 40-year-old) under stable GAHT ≥6 months were enrolled. Total testosterone levels and visual analogue scale (VAS)-based satisfaction scores were evaluated.
    UNASSIGNED: No difference was observed in age between the CPA and SPL groups (median [IQR], 22 [20-24] years and 23 [20-26] years, respectively). The duration of GAHT was longer in CPA group than in SPL group (18 [10-32] months vs. 12 [8-21] months, p = 0.009). Total testosterone levels were significantly lower with CPA treatment (25 mg/d) than with SPL treatment (100 mg/d) (median [IQR]: 0.7 [0.7-2.1] nmol/L vs. 13.0 [6.0-17.8] nmol/L, p < 0.001). The proportion of total testosterone levels reaching the recommended range was significantly higher in CPA group than in SPL group (75.0% vs. 11.3%, p < 0.001). VAS-based satisfaction scores for erection decreased and figure feminization were higher in CPA group than in SPL group, which remained unchanged after adjusting for age, treatment duration, estradiol dose, and comorbid mental disorders (p < 0.05). The prolactin levels were higher in CPA group than in SPL group (18.9 [11.8-28.1] ng/ml vs. 11.8 [7.9-18.4] ng/ml, p < 0.001). No severe safety events were reported in both groups.
    UNASSIGNED: In Chinese transgender women, CPA was more effective than SPL in lowering testosterone levels. Additionally, VAS scores indicated greater satisfaction with erection decreased and figure feminization using CPA compared to SPL.

    女性最常见的脱发类型是女性雄激素性脱发(FAGA),以图案化分布的进行性脱发为特征。许多口服疗法,包括螺内酯(醛固酮拮抗剂),雄激素受体阻滞剂(例如,氟他胺/比卡鲁胺),5-α-还原酶抑制剂(例如,非那雄胺/度他雄胺),和口服避孕药,靶向雄激素转化和与各自受体结合的机制,因此可以用于治疗FAGA。尽管FAGA的口服治疗取得了重大进展,对有妇科恶性肿瘤病史的患者的治疗,全世界女性最常见的癌症,可能仍然是一个问题。在这次审查中,我们关注抗雄激素治疗FAGA患者的安全性.为此,在PubMed上进行了有针对性的文献综述,利用相关的搜索条件。总而言之,螺内酯对于FAGA的全身治疗似乎是安全的,即使是高危人群。然而,对于有妇科恶性肿瘤病史的患者,其他药物的安全性仍然存在普遍的不确定性。需要进一步的研究来评估其在FAGA患者中的长期安全性和风险因素,以建立最佳的风险评估和治疗选择方案.
    The most common type of alopecia in women is female androgenetic alopecia (FAGA), characterized by progressive hair loss in a patterned distribution. Many oral therapies, including spironolactone (an aldosterone antagonist), androgen receptor blockers (e.g., flutamide/bicalutamide), 5-alpha-reductase inhibitors (e.g., finasteride/dutasteride), and oral contraceptives, target the mechanism of androgen conversion and binding to its respective receptor and therefore could be administered for the treatment of FAGA. Despite significant advances in the oral treatment of FAGA, its management in patients with a history of gynecological malignancies, the most common cancers in women worldwide, may still be a concern. In this review, we focus on the safety of antiandrogens for the treatment of FAGA patients. For this purpose, a targeted literature review was conducted on PubMed, utilizing the relevant search terms. To sum up, spironolactone seems to be safe for the systemic treatment of FAGA, even in high-risk populations. However, a general uncertainty remains regarding the safety of other medications in patients with a history of gynecologic malignancies, and further studies are needed to evaluate their long-term safety in patients with FAGA and risk factors to establish an optimal risk assessment and treatment selection protocol.

    目的:多囊卵巢综合征(PCOS)在年轻女性中广泛报道,和抗雄激素用于治疗这些患者的多毛症和痤疮。肌醇的保护作用,口服避孕药,据报道,PCOS女性的牙周组织和高敏C反应蛋白(hsCRP)水平与胰岛素增敏剂有关。然而,乙酸环丙孕酮/乙炔雌二醇(CPA/EE)尚未研究。这项横断面研究探讨了与未服用药物的女性相比,使用CPA/EE药物组合的PCOS女性的牙周状况和全身性炎症。
    方法:共有150名参与者被纳入三组:50名新诊断的PCOS女性未服药(N-PCOS);50名PCOS女性在过去6个月内服用CPA/EE组合(PCOS+CPA/EE);50名全身健康女性(对照组)。人体测量,生物化学,牙周参数,并记录健康相关生活质量问卷.
    结果:N-PCOS和PCOS+CPA/EE组hsCRP水平无显著差异,牙龈指数,探查时出血,腰围,腰臀比(P>0.05)。PCOS+CPA/EE组的牙龈厚度和角化组织宽度明显大于N-PCOS组(P≤0.05);这些与对照组相当(P>.05)。回归分析显示探查出血与牙龈指数显著相关,临床依恋水平,和hsCRP(P≤0.05)。
    结论:CPA/EE组合不影响PCOS女性的牙周和全身炎症状态,与未服用药物的PCOS女性相比,CPA/EE消费者的局部和全身炎症水平相似.然而,它可能在增加这些患者的牙龈厚度和角化组织宽度中起作用。
    Polycystic ovary syndrome (PCOS) is widely reported among young females, and anti-androgens are used for treating hirsutism and acne in these patients. The protective effects of myo-inositol, oral contraceptives, and insulin sensitizers have been reported on the periodontium and high-sensitivity C-reactive protein (hsCRP) levels in PCOS females. However, cyproterone acetate/ethinyl estradiol (CPA/EE) has not yet been studied. This cross-sectional study explores the periodontal status and systemic inflammation in PCOS women on CPA/EE drug combination compared to females not on medication.
    A total of 150 participants were enrolled into three groups: 50 newly diagnosed PCOS females not on medication (N-PCOS); 50 PCOS females consuming CPA/EE combination for the last 6 months (PCOS+CPA/EE); and 50 systemically healthy females (control group). Anthropometric, biochemical, periodontal parameters, and health-related quality of life questionnaires were recorded.
    N-PCOS and PCOS+CPA/EE groups showed a nonsignificant difference in hsCRP levels, Gingival Index, bleeding on probing, waist circumference, and waist-hip ratio (P > .05). Gingival thickness and keratinized tissue width were significantly greater in the PCOS+CPA/EE than the N-PCOS group (P ≤ .05); however, these were comparable with the control group (P > .05). Regression analysis showed significant association of bleeding on probing with Gingival Index, clinical attachment level, and hsCRP (P ≤ .05).
    CPA/EE combination does not influence the periodontal and systemic inflammatory status in PCOS females, as similar levels of local and systemic inflammation were observed in CPA/EE consumers compared with PCOS females not on medication. However, it might play a role in increasing gingival thickness and keratinized tissue width in these patients.

    目标:性别确认激素治疗(GAHT)导致拟人化的可测量变化,生化和激素变量,对患者及其卫生保健专业人员指导治疗很重要。这项研究试图量化响应于GAHT启动而发生的变化。
    方法:我们对开始GAHT的变性人和性别多样化(TGD)患者的结局进行了回顾性队列研究。主要结果是患者比例和开始GAHT后达到最佳激素水平所需的时间。进行其他分析以评估临床和生化因素是否与达到目标激素水平的可能性相关。
    结果:纳入345例患者。在154个跨男性个体中,116(75%)在中位4个月(IQR4-9)的随访期间达到睾酮水平>10nmol/L。在变性人中,没有临床或生化因素与达到治疗性睾酮浓度的可能性显着相关。在191名跨女性个体中,131(72%)在中位4个月的随访期间达到睾酮水平<2.0nmol/L(IQR3-9)。与睾酮抑制可能性增加相关的因素是使用皮下雌二醇植入物以及醋酸环丙孕酮作为雄激素拮抗剂。在重复测量脂质的过程中观察到不同方向的变化,肝功能,以及跨男性和跨女性个体之间的血细胞计数,反映睾酮和雌二醇对作为常规临床护理一部分的生化检查的重要影响。
    结论:大多数TGD患者在GAHT开始后9个月内达到目标睾酮水平。GAHT的副作用很少见,通常是温和的。
    OBJECTIVE: Gender affirming hormone treatment (GAHT) results in measurable changes to anthropomorphic, biochemical and hormonal variables that are important to patients and their health care professionals to guide treatment. This study sought to quantify changes which occur in response to initiation of GAHT.
    METHODS: We performed a retrospective cohort study of outcomes in transgender and gender diverse (TGD) patients starting GAHT. The primary outcome was proportion of patients and time required to achieve optimal hormone levels after commencement of GAHT. Additional analyses were performed to assess whether clinical and biochemical factors were associated with likelihood of achieving target hormone levels.
    RESULTS: 345 patients were included. Among 154 transmasculine individuals, 116 (75%) achieved a testosterone level >10 nmol/L during follow-up at a median of 4-months (IQR 4-9). No clinical or biochemical factors were significantly associated with likelihood of reaching therapeutic testosterone concentrations in transmen. Among 191 transfeminine individuals, 131 (72%) achieved a testosterone level <2.0 nmol/L during follow-up at a median of 4-months (IQR 3-9). Factors associated with increased likelihood of testosterone suppression were use of subdermal estradiol implants as well as cyproterone acetate as an androgen antagonist. Changes in differing directions were observed during repeated measures of lipids, liver function, and blood count between transmasculine and transfeminine individuals, reflecting the important effects of testosterone and estradiol on biochemical tests ordered as part of routine clinical care.
    CONCLUSIONS: Most TGD patients achieve target testosterone levels within 9 months of GAHT initiation. Adverse effects of GAHT are rare, and are usually mild.

    背景:醋酸环丙孕酮(CPA)是一种合成的孕酮衍生物,于1970年代引入,被规定为无法手术的前列腺癌的抗雄激素疗法,男性的性偏差,和女性雄激素化的迹象。2020年,CPA产品特征摘要(SmPC)进行了修订,以包括有关(1)累积剂量增加的脑膜瘤风险和(2)脑膜瘤或脑膜瘤病史患者的禁忌症的最新特殊警告和预防措施。分发了直接医疗保健专业通信(DHPC)。欧洲药物管理局的药物警戒风险评估委员会要求欧洲市场授权持有人进行一项调查,以评估医生对更新的关键安全信息的了解。这项研究的主要目的是衡量医生的意识(即,他们是否收到并审查了修订的SmPC和DHPC)以及对由于脑膜瘤风险而限制使用CPA单药治疗的关键安全性信息的知识和理解水平。
    方法:这项基于网络的横断面调查是针对皮肤科医生进行的,内分泌学家,妇科医生,泌尿科医师,肿瘤学家,精神病医生,和法国的全科医生,德国,波兰,西班牙,以及在过去12个月内使用CPA单药治疗的荷兰,以评估对CPA单药治疗相关脑膜瘤风险的认识。
    结果:在参加的613名医生中,85%正确地表明,CPA单药治疗应以最低有效剂量开处方,75%正确表明脑膜瘤的风险随着CPA单药治疗剂量的增加而增加,73%的人正确地指出,如果患者被诊断患有脑膜瘤,则必须永久停止含CPA产品的治疗。总的来说,40%的医生报告说已经接受了DHPC,42%的人报告收到了修订后的SmPC。
    结论:尽管收到更新的SmPC和DHPC的召回率很低,大多数接受调查的医生都意识到脑膜瘤的风险以及降低风险的措施。
    BACKGROUND: Cyproterone acetate (CPA) is a synthetic progesterone derivative introduced in the 1970s and prescribed as antiandrogenic therapy for inoperable prostate cancer, sexual deviations in men, and signs of androgenization in women. In 2020, the CPA summary of product characteristics (SmPC) was revised to include an updated special warning and precaution about (1) the risk of meningioma with increasing cumulative dose and (2) contraindication in patients with meningioma or history of meningioma. A Direct Healthcare Professional Communication (DHPC) was distributed. The European Medicine Agency\'s Pharmacovigilance Risk Assessment Committee requested that marketing authorization holders in Europe conduct a survey to assess physicians\' knowledge of the updated key safety information. The primary objective of this study was to measure physicians\' awareness (i.e., did they receive and review the revised SmPC and DHPC) and level of knowledge and understanding of the key safety information pertaining to the restricted use of CPA monotherapy because of the risk of meningioma.
    METHODS: This cross-sectional web-based survey was administered to dermatologists, endocrinologists, gynecologists, urologists, oncologists, psychiatrists, and general practitioners in France, Germany, Poland, Spain, and the Netherlands who had prescribed CPA monotherapy in the previous 12 months to assess awareness of the risk of meningioma associated with CPA monotherapy.
    RESULTS: Of the 613 physicians who participated, 85% correctly indicated that CPA monotherapy should be prescribed with the lowest effective dose, 75% correctly indicated that the risk of meningioma increases with increasing cumulative CPA monotherapy doses, and 73% correctly indicated that treatment with CPA-containing products must be stopped permanently if a patient is diagnosed with meningioma. Overall, 40% of physicians reported having received the DHPC, and 42% reported having received the revised SmPC.
    CONCLUSIONS: Despite low recall of receipt of the updated SmPC and DHPC, most physicians surveyed are aware of the meningioma risk and actions to mitigate the risk.

    UNASSIGNED: Comparison of hormonal, metabolic and inflammatory markers of glutathione with metformin and Diane-35 in a rat model of PCOS induced by dehydroepiandrosterone.
    UNASSIGNED: Twenty-five female rats were randomized into four groups. Group 1 was administered a subcutaneous dose of 0.2 ml saline/day. Group 2 was given 0.2 ml of 1% carboxymethyl cellulose (CMC)/day orally for 28 days. A PCOS model was established with DHEA in rats. Group 3 was given 4.5 mg/kg/day of Diane-35 orally dissolved in 1% CMC for 28 days. Group 4 was given 300 mg/kg/day of metformin orally dissolved in 1 ml of saline for 28 days, and Group 5 was administered 100 mg/kg of glutathione intraperitoneally on days 35, 42, and 49. On day 56, the rats were sacrificed. Serum markers and follicle count were examined.
    UNASSIGNED: Serum IL-6, hs-CRP, insulin, testosterone, SHBG, and MDA values were significantly lower in the glutathione group than in the PCOS group (p = 0.0006, p = 0.023, p = 0.0082, p = 0.0007, p = 0.0048, and p < 0.0001, respectively).The number of all follicles was similar between the control and glutathione groups (p < 0.05). When we compared the other groups with the PCOS group, the number of primary, secondary, atretic, and cystic follicles was significantly lower in the metformin and glutathione groups. The number of primordial and antral follicles was significantly higher than in the PCOS group.
    UNASSIGNED: Glutathione plays anti-inflammatory and antioxidant roles, similar to metformin, by lowering serum IL-6, insulin, testosterone, CRP, and MDA levels; decreasing atretic/cystic follicle count; and improving antral follicle count and folliculogenesis in PCOS patients.

    背景:性别认同不同于生物性别和社会规范的个体被定义为变性者。有时变性人接受性别确认激素治疗,持续一生,这对评估其潜在的长期影响至关重要。此外,跨性别可以代表一个易感人群,在风险评估中需要特别注意,包括有针对性的动物模型的开发。该研究的目的是通过设置适当剂量的激素治疗和选择特定的生物标志物来评估性别转变,从而实现啮齿动物的去血管化-女性化模型。由于与生殖功能密切相关,因此应特别注意甲状腺稳态。将四只雄性成年大鼠/组皮下暴露于三种剂量加上β-雌二醇戊酸酯和乙酸环丙孕酮的对照:0.0450.2(低),0.09+0.2(中)和0.18+0.2(高)毫克/剂,五次/周。选择剂量时考虑了针对跨性别女性的最新建议。精子计数,组织病理学分析(睾丸,肝脏,甲状腺),睾丸激素,雌二醇,评估了三碘甲状腺原氨酸和促甲状腺激素的血清水平以及性别双态CYP450的基因表达。
    结果:剂量诱导女性化-去血管化作用:相应顺位时睾酮血清水平降低,增加雌二醇,男性生殖功能受损和性别特异性CYP肝脏表达逆转。然而,中、高剂量引起明显的肝毒性,低剂量被认为是最佳选择,也用于风险评估的长期研究。甲状腺的改变表明滤泡细胞肥大,高剂量的促甲状腺激素血清水平增加。
    结论:实施模拟性别确认激素治疗效果的动物模型对于支持变性人的临床研究和填补数据空白至关重要,以确保适当的风险评估和更准确的,为变性人提供个性化护理。
    Individuals whose gender identity differs from the biological sex and the social norms are defined as transgender. Sometimes transgender undergo gender affirming hormone therapy, which lasts for the entire life making essential to evaluate its potential long-term effects. Moreover, transgender can represent a susceptible sub-group of population and specific attention is needed in risk assessment, including the development of targeted animal models. Aim of the study is the implementation of a rodent demasculinizing-feminizing model through the setting of appropriate dose of hormone therapy and the selection of specific biomarkers to evaluate the sex transition. Specific attention is paid to thyroid homeostasis due to the close link with reproductive functions. Four male adult rats/group were subcutaneously exposed to three doses plus control of β-estradiol valerate plus cyproterone acetate at: 0.045 + 0.2 (low), 0.09 + 0.2 (medium) and 0.18 + 0.2 (high) mg/dose, five times/week. The doses were selected considering the most recent recommendations for transgender woman. Sperm count, histopathological analysis (testis, liver, thyroid), testosterone, estradiol, triiodothyronine and thyroid-stimulating hormone serum levels and gene expression of sex dimorphic CYP450 were evaluated.
    The doses induced feminizing-demasculinizing effects: decreased testosterone serum levels at the corresponding cisgender, increased estradiol, impairment of male reproductive function and reversal of sex-specific CYP liver expression. However, the medium and high doses induced marked liver toxicity and the low dose is considered the best choice, also for long-term studies in risk assessment. The alterations of thyroid indicated follicular cell hypertrophy supported by increased thyroid-stimulating hormone serum levels at the higher doses.
    The implementation of animal models that mimic the effects of gender affirming hormone therapy is essential for supporting clinical studies in transgender people and filling data gap in order to ensure an appropriate risk assessment and a more accurate, personalized care for transgender people.

    南美弱电鱼,奥马洛姆,在两性中全年都表现出领土侵略。为了检查快速雄激素调节在非繁殖攻击中的作用,我们服用醋酸环丙孕酮(CPA),一种有效的雄激素受体抑制剂,对男性和女性来说,就在上演激动互动之前。野生捕获的鱼被注射了CPA,30分钟后,成对的性内二元。然后,我们记录了包含运动表现和社会电信号发射的激动行为。我们发现,注册会计师对两种性别的攻击性水平或从事攻击性行为的动机都没有明显的影响。然而,CPA特别降低了男性和女性二元群体中社会电信号的表达。该效应与状态有关,因为它只影响从属电通信行为,在他们的电信号中发出短暂的中断(“关”)。这项研究首次证明了通过雄激素受体介导的对非育种攻击的直接和快速的雄激素作用。在此硬骨鱼模型中阐明非繁殖侵略的机制,可以使我们更好地了解脊椎动物侵略背后的潜在保守或趋同的神经内分泌机制。
    The South American weakly electric fish, Gymnotus omarorum, displays territorial aggression year-round in both sexes. To examine the role of rapid androgen modulation in non-breeding aggression, we administered acetate cyproterone (CPA), a potent inhibitor of androgen receptors, to both male and females, just before staged agonistic interactions. Wild-caught fish were injected with CPA and, 30 min later, paired in intrasexual dyads. We then recorded the agonistic behavior which encompasses both locomotor displays and emission of social electric signals. We found that CPA had no discernible impact on the levels of aggression or the motivation to engage in aggressive behavior for either sex. However, CPA specifically decreased the expression of social electric signals in both males and female dyads. The effect was status-dependent as it only affected subordinate electrocommunication behavior, the emission of brief interruptions in their electric signaling (\"offs\"). This study is the first demonstration of a direct and rapid androgen effect mediated via androgen receptors on non-breeding aggression. Elucidating the mechanisms involved in non-breeding aggression in this teleost model allows us to better understand potentially conserved or convergent neuroendocrine mechanisms underlying aggression in vertebrates.

    SLE患者年龄较大,26.3±5.8年与20.1±2.3年,p=0.006。所有的人体测量,身体成分,和实验室变量在基线时相同。虽然烦躁不安似乎更大,在基线时CO组性功能较低,这在年龄调整后取消了。两种处理诱导相似的生化和激素变化。肌酐,血红蛋白和胆固醇显著下降,而睾酮在两组中被抑制到相同的水平:SLE组中为3.22[1.47-5.0]nmol/L,CO组中为2.41[0.55-8.5]nmol/L,p=0.65。在两组中都注意到身体成分向女性身体的显着变化。两组患者均无明显改善,虽然性欲和功能在六个月时都有所下降,p<0.001。
    两种治疗方法的临床变化相似。在这个阶段,SLE,反复引起全天血清雌二醇的惊人移动,似乎与CO方法相比没有任何优势。
    UNASSIGNED: Chronic gender-affirming hormone therapy (GAHT) with sublingual estradiol (SLE) has not been studied. We aimed to compare GAHT with SLE only, to combined oral (CO) estradiol and cyproterone acetate, in treatment-naive trans women.
    UNASSIGNED: Twenty-two trans women enrolled into either the CO arm or the SLE-only arm (0.5 mg four times daily) in this 6-month prospective study. Anthropometric and laboratory variables were collected at baseline and 3 and 6 months. At the study beginning and end, body composition was measured by dual-energy X-ray absorptiometry and bioelectrical impedance, and gender dysphoria, sexual desire, and function were assessed by validated questionnaires.
    UNASSIGNED: Subjects in the SLE were older, 26.3±5.8 years versus 20.1±2.3 years, p=0.006. All anthropometric, body composition, and laboratory variables were identical at baseline. Although dysphoria appeared greater, and sexual function lower at baseline in the CO group, this canceled out after age adjustment. Both treatments induced similar biochemical and hormonal changes. Creatinine, hemoglobin and cholesterol decreased significantly, while testosterone was suppressed to the same level in both groups: 3.22 [1.47-5.0] nmol/L in the SLE group and 2.41 [0.55-8.5] nmol/L in the CO, p=0.65. Significant changes in body composition toward a more feminine body were noted in both groups. Dysphoria did not significantly improve in either group, while sexual desire and function decreased at six months in both, p<0.001.
    UNASSIGNED: Both treatments achieved similar clinical changes. At this stage, SLE, which repeatedly induces alarming excursions of serum estradiol throughout the day, appears to offer no advantage over the CO approach.
