子宫内膜异位症(endometriosis,EMs)是育龄期妇女常见的良性疾病,但具有侵袭、种植及复发等恶性倾向,主要表现为痛经、月经紊乱、性交痛等,与不孕关系密切,其发病机制尚不明确。近年来多数研究认为,子宫内膜异位症是一种自身免疫性疾病,自身免疫反应在其发病机制中可能起一定作用。检测自身抗体可能为子宫内膜异位症的早期诊断提供新的辅助指标。 Endometriosis (EMs) is a common benign disease in women of childbearing age, but has malignant tendency of invasion, implantation and relapse. The main manifestations are dysmenorrhea, menstrual disorders, painful intercourse and so on, which are closely related to infertility. The pathogenesis is not clear. Most studies in recent years that endometriosis is an autoimmune disease, autoimmune response may play a role in its pathogenesis. Detection of autoantibodies may provide new ancillary indicators for the early diagnosis of endometriosis.
