摘要:

功能性下丘脑性闭经(functional hypothalamic amenorrhea,FHA)是一种中枢性、非器质性、可逆性闭经,由体内外各种因素,如能量摄入不足、过度运动、心理应激及遗传易感性,诱发下丘脑-垂体-卵巢(hypothalamic-pituitary-ovarian,HPO)轴功能抑制所致。近年来,低能量可用性(low energy availability,LEA)为理解FHA的发生提供了理论框架。机体LEA时会启动适应性反应机制,优先维持生命必需功能,同时抑制高能耗的生殖活动,表现为外周代谢信号水平改变及下丘脑Kisspeptin/神经激肽B/强啡肽(Kisspeptin/neurokinin B/dynorphin,KNDy)神经元功能受损,最终导致促性腺激素释放激素脉冲分泌障碍及HPO轴功能减退。基于改善LEA治疗FHA的策略,恢复能量可用性是核心,基础治疗以生活方式干预为主,包括营养支持、合理运动和心理干预;此外,基于Kisspeptin及其受体的靶向治疗也展现出潜在应用前景。

Abstract:

Functional hypothalamic amenorrhea (FHA) is a central, non-organic, and reversible form of amenorrhea, resulting from the suppression of hypothalamic-pituitary-ovarian (HPO) axis induced by various intrinsic and extrinsic factors, such as insufficient energy intake, excessive physical activity, psychological stress, and genetic susceptibility. In recent years, low energy availability (LEA) has provided a unifying theoretical framework for understanding the pathophysiology of FHA. Under LEA, the body initiates adaptive responses that prioritize vital physiological functions while suppressing energy-demanding reproductive processes. These adaptations are characterized by the alterations in peripheral metabolic signals and impaired function of hypothalamic Kisspeptin/neurokinin B/dynorphin (KNDy) neurons, ultimately leading to the disrupted gonadotropin-releasing hormone (GnRH) pulsatility and the attenuation of HPO axis function. Based on improving LEA, strategies for treating the FHA primarily focus on restoring energy availability. First-line management mainly involves lifestyle interventions, including nutritional support, appropriate exercise modification, and psychological intervention. In addition, the targeted therapies involving Kisspeptin and its receptor have also shown a potential therapeutic prospect.
