Membranous nephropathy (MN) is characterized by deposition of immune complexes leading to thickening of glomerular basement membranes. Over time, the understanding of MN has evolved, with the identification of specific autoantibodies against novel podocyte antigens and the unraveling of intricate pathogenic pathways. Although the anti-CD20 monoclonal antibody rituximab is favored as part of the initial therapy in MN, a subgroup of MN patients may be resistant to rituximab necessitating the use of alternative agents such as cytotoxic therapies. In addition, newer agents such as novel anti-CD20 monoclonal antibodies, therapies targeting the CD38-positive plasma cells and anti-complement therapy are being studied in patients who are resistant to traditional treatment strategies. This manuscript furnishes a review of the novel developments in the pathophysiology of MN including the identification of target antigens and current treatment standards for MN, concentrating on evidenced-based interventions designed to attain remission and to prevent disease progression.
膜性肾病(MN)的特征是免疫复合物的沉积导致肾小球基底膜增厚。随着时间的推移,对 MN 的认识不断发展,新型足细胞抗原特异性自身抗体的鉴定和复杂发病机制的阐明。尽管抗 CD20 单克隆抗体利妥昔单抗被作为 MN 初始治疗的一部分,但一小部分 MN 患者可能对利妥昔单抗耐药,需要使用细胞毒性药物等替代药物。此外,新型抗 CD20 单克隆抗体等新型药物、针对 CD38 阳性浆细胞的治疗方法和抗补体治疗方法正在对传统治疗策略耐药的患者中进行研究。本文综述了 MN 的病理生理学方面的新进展,包括靶抗原的鉴定和 MN 的当前治疗标准,重点介绍了旨在实现缓解和预防疾病进展的基于证据的干预措施。
