概括
移植后的血栓性微血管病变 (PT-TMA) 具有多种风险因素和不良预后,特别是在晚发病的情况下. 用eculizumab治疗的早期PT-TMA显示出更好的结果,但晚期爱斯坦-巴尔病毒相关的淋巴增殖障碍是令人担忧的.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.

- 补充生物学 补充生物学
背景情况:
- 血栓式微血管病变 (TMA) 是移植后的一种严重并发症.
- 风险因素,对补充成分的自身抗体患病率,以及移植后TMA (PT-TMA) 的预后仍然不明.
研究的目的:
- 调查PT-TMA患者的风险因素,自身抗体概况和结果.
- 为了比较PT-TMA患者与没有PT-TMA的移植受体和健康对照.
主要方法:
- 从13名PT-TMA患者 (2011-2018) 的临床和实验室数据的回顾性分析.
- 与酶相关的免疫吸收试验 (ELISA) 检测对补充成分的自身抗体.
- 将PT-TMA患者与对照组进行比较.
主要成果:
- 在69%的患者中,PT-TMA发生了超出氨酸抑制剂 (CNIs) 的风险因素.
- 早期发病的PT-TMA (6个月内) 与供体特异性抗体 (DSA),补体相关病和急性排斥有关.

- 在早期开始的PT-TMA中,eculizumab治疗改善了功能.
- 三名患者患上了与爱斯坦-巴尔病毒相关的移植后淋巴增殖障碍 (EPTLD),引起了人们的担忧.
结论:
- 根据移植后发病时间,PT-TMA的风险因素和表现有所不同.
- 预后通常不好,但早期的PT-TMA可能会受益于eculizumab.
- 迟到的EPTLD的出现需要进一步的调查和监测.

Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
