Postmenopausal osteoporosis (PMOP) is a systemic bone metabolism disease, characterized by progressive bone loss following menopause and a subsequent increase in fracture risk. Estrogen deficiency as a result of menopause is known to increase bone resorption and accelerate bone loss. Furthermore, postmenopausal women may exhibit iron accumulation, in addition to estrogen deficiency. Elevated iron levels are a risk factor for PMOP in postmenopausal women, and reducing the iron overload has been demonstrated to benefit bone cell metabolism and improve the bone by normalizing osteoclastic bone resorption and formation. The identification of hepcidin was a key development in the field of iron metabolism in the previous decade. We hypothesize that hepcidin may aid in the prevention and treatment of PMOP due to its capacity to control body iron stores and its intrinsic effects on osteoblast function. The aim of the current review was to highlight the role of iron accumulation in the pathogenesis of PMOP and to evaluate the possible use of hepcidin as a potential therapy for this condition.
绝经后骨质疏松症(PMOP)是一种全身性骨代谢疾病,其特征是绝经后骨量逐渐流失以及随后骨折风险增加。已知绝经导致的雌激素缺乏会增加骨吸收并加速骨质流失。此外,绝经后女性除雌激素缺乏外,还可能出现铁蓄积。铁水平升高是绝经后女性患PMOP的一个风险因素,并且已证明减少铁过载可通过使破骨细胞骨吸收和形成正常化来有益于骨细胞代谢并改善骨骼。在过去十年中,铁调素的发现是铁代谢领域的一项关键进展。我们推测,铁调素可能因其控制体内铁储存的能力及其对成骨细胞功能的内在影响而有助于预防和治疗PMOP。本综述的目的是强调铁蓄积在PMOP发病机制中的作用,并评估铁调素作为这种疾病潜在治疗方法的可能性。
