概括

移植中的延迟移植功能 (DGF) 具有多种不同的生物学基础. 循环死亡后捐赠 (DCD) 长期DGF的脏显示代谢和压力反应受损,这表明目前的定义是不够的.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
移植生物学移植生物学
蛋白质组学是指蛋白质组学.

背景情况:

延迟移植功能 (DGF) 是移植后的常见并发症,影响长期结果.
目前的DGF定义,基于第一周的透析需求,可能无法完全捕捉潜在的损伤模式.
循环死亡 (DCD) 之后的捐赠脏特别容易受损伤和DGF.

研究的目的:

调查与不同DGF持续时间相关的DDC脏捐赠者的生物途径差异.
识别与直接功能 (IF),短期DGF (SDGF) 和长期DGF (LDGF) 相对应的蛋白质组签名.

主要方法:

使用无标签定量 (LFQ) 蛋白质组学分析了30个DCD脏活检.
样本分层成IF (n=10),SDGF (1-6天,n=10) 和LDGF (7-22天,n=10) 组.
利用发明路径分析 (IPA) 识别差异丰富的蛋白质和相关的生物路径.

主要成果:

与IF脏相比,SDGF脏显示出高调节的应激反应途径.
与IF和SDGF脏相比,LDGF脏表现出应激反应受损和显著的代谢缺陷.
在所有样本中共鉴定出3378种蛋白质.

结论:

患有短期DGF的DDC脏显示急性细胞损伤和修复通路激活的迹象.
长期DGF (7天以上) 的DDC脏显示最小的代谢和抗氧化反应,表明严重的功能障碍.
目前的DGF定义可能不足以区分损伤模式和预测DCD移植的结果.

Kidney Transplant I: Introduction

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
