摘要
简介本研究比较了奥比妥珠单抗和利妥昔单抗治疗原发性膜性肾病患者的有效性和安全性:方法:原发性膜性肾病患者,尿蛋白≥3.5 g/24 小时,估计肾小球滤过率(eGFR)≥30 mL/min/1.73 m2,且使用血管紧张素转换酶抑制剂/血管紧张素 II 受体阻滞剂和奥比妥珠单抗或利妥昔单抗治疗 6 个月的患者被纳入,并根据年龄、性别、尿蛋白、eGFR 和抗磷脂酶 A2 受体 (PLA2R) 抗体滴度进行倾向评分匹配(比例:1:2)。主要结果定义为 12 个月时部分或完全缓解的组合。采用逻辑回归模型、卡普兰-梅耶曲线和绝对风险差异比较了奥比妥珠单抗和利妥昔单抗的治疗效果和安全性:研究共纳入63名原发性膜性肾病患者,其中21名患者接受了奥比妥珠单抗治疗,42名患者接受了利妥昔单抗治疗。12个月后,奥比妥珠单抗组21名患者中有20名患者达到了主要治疗效果,利妥昔单抗组42名患者中有28名患者达到了主要治疗效果(奥比妥珠单抗与利妥昔单抗相比:95%对67%;几率):95%对67%;几率比(OR):10.00,95%置信区间(CI):1.21-82.35,P=0.03)。此外,奥比妥珠单抗组患者获得的完全缓解率更高(奥比妥珠单抗 vs. 利妥昔单抗:38% vs. 14%; OR=0.03):38% vs. 14%; OR:3.69,95% CI:1.08-12.68,P=0.04)。在PLA2R相关原发性膜性肾病亚组分析中,奥比妥珠单抗组患者的CD19 B细胞计数较低(CD19 B细胞计数:中位数(IQR)0(0-6)个/ul vs. 20(3-58)个/ul,P=0.002),更容易达到免疫学缓解(定义为PLA2R抗体结论):我们的研究表明,与利妥昔单抗相比,奥比妥珠单抗在12个月时临床缓解的几率更高,这可能是由于原发性膜性肾病患者在6个月时免疫学缓解率更高,且安全性相似。
期刊介绍:
The Clinical Journal of the American Society of Nephrology strives to establish itself as the foremost authority in communicating and influencing advances in clinical nephrology by (1) swiftly and effectively disseminating pivotal developments in clinical and translational research in nephrology, encompassing innovations in research methods and care delivery; (2) providing context for these advances in relation to future research directions and patient care; and (3) becoming a key voice on issues with potential implications for the clinical practice of nephrology, particularly within the United States. Original manuscript topics cover a range of areas, including Acid/Base and Electrolyte Disorders, Acute Kidney Injury and ICU Nephrology, Chronic Kidney Disease, Clinical Nephrology, Cystic Kidney Disease, Diabetes and the Kidney, Genetics, Geriatric and Palliative Nephrology, Glomerular and Tubulointerstitial Diseases, Hypertension, Maintenance Dialysis, Mineral Metabolism, Nephrolithiasis, and Transplantation.
