概括
埃奎利祖马布有效治疗由抗补因子H (CFH) 抗体引起的非典型血溶性尿素性综合征 (aHUS). 治疗导致抗体水平降低和持续缓解,eculizumab和mycophenolate mofetil显示出良好的安全性.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 免疫学 免疫学 免疫学
- 儿科 儿科 儿科
背景情况:
- 儿童的非典型血溶性尿素综合征 (aHUS) 可能是由对补充因子H (CFH) 的自身抗体引发的,占病例的5-50%.
- 获得的自身免疫性aHUS需要等离子体交换和免疫抑制等治疗;eculizumab是最近的治疗选择.
研究的目的:
- 评估eculizumab在患有抗CFH抗体相关的aHUS的儿科患者的疗效和安全性.
- 评估各种免疫抑制疗法与eculizumab结合对抗CFH抗体水平和临床结果的影响.
主要方法:
- 多中心,回顾性研究分析了12名患有抗CFH抗体相关HUS的儿童的结局,这些儿童接受了eculizumab治疗.
- 患者接受了eculizumab,有些人还接受了血交换或IgG吸附.
- 与没有免疫抑制的对照组一起,给予了各种免疫抑制方案,包括mycophenolate mofetil (MMF),类固醇和rituximab.
主要成果:
- 治疗eculizumab导致抗CFH抗体水平显著下降,无论使用的免疫抑制疗法.
- 所有患者都实现了缓解,没有观察到复发,并保持了估计的球膜过率 (eGFR) 超过70mL/min/1.73m2.
- 平均11个月后,70%的患者停止使用eculizumab;平均36个月后,75%的患者停止使用MMF,持续缓解.
结论:
- 埃奎利祖马布对于诱导和维持抗CFH抗体相关的aHUS缓解是有效和安全的,减少了快速降低抗CFH标位的紧迫性.
- 结合eculizumab和MMF单疗似乎足以控制非印第安或不那么严重的抗CFH抗体相关的aHUS.
- 无论免疫抑制策略如何,大多数患者的抗CFH抗体标量都下降,这凸显了eculizumab的主要作用.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
