There are an increasing number of reports on the safe use of rituximab (RTX), a chimeric anti-CD20 monoclonal antibody, in pregnant women with hematological malignancies or refractory autoimmune diseases. In 2014, the use of RTX for patients with complicated steroid-dependent nephrotic syndrome (SDNS) was approved in Japan. We herein report a woman with childhood-onset complicated SDNS due to focal and segmental glomerulosclerosis, who had two successful pregnancies while receiving RTX maintenance therapy. No adverse complications were observed during the pregnancies, and she delivered healthy newborns. This case suggested that RTX may be used safely in pregnant women complicated with SDNS.
越来越多的报告表明,在患有血液系统恶性肿瘤或难治性自身免疫性疾病的孕妇中,使用利妥昔单抗(RTX)是安全的。RTX 是一种嵌合抗 CD20 单克隆抗体。2014 年,RTX 获批用于治疗伴有复杂型激素依赖性肾病综合征(SDNS)的患者。本文报告了一例儿童起病的伴有局灶节段性肾小球硬化的复杂型 SDNS 患者,该患者在接受 RTX 维持治疗的同时成功妊娠两次。两次妊娠期间均未发生不良并发症,患者顺利分娩健康新生儿。该病例提示,RTX 可能可安全用于伴有 SDNS 的孕妇。
