概括

分配系统 (KAS) 在高度敏感的患者中增加了移植,但结果没有恶化. 虽然KAS减少了种族差异,但黑人患者仍然存在显著的不平等.

科学领域:

腎臟病學 (nephrology) 是一種醫學.
移植免疫学移植免疫学
医疗保健服务研究医疗服务研究

背景情况:

美国器官共享网络于2014年实施了分配系统 (KAS),以解决器官分配方面的差异.
高度敏感的患者 (计算面板反应性抗体[cPRA] ≥97%) 由于抗体介导的排斥风险,面临接受脏移植的挑战.
了解KAS对高度敏感个体的移植结果的影响及其对种族差异的影响至关重要.

研究的目的:

为了比较高度敏感的患者 (cPRA ≥97%) 在实施KAS之前和之后的结果.
在KAS后的时代,检查高度敏感的患者相对于低风险接受者 (cPRA <10%) 的结果.
确定KAS对移植中的种族差异的影响.

主要方法:

对国家注册数据的回顾性分析.
在KAS实施前 (2011-2013年) 和之后 (2015-2017年) 的3年期间,确定了已故捐赠者移植等候名单上的两个成年候选人队伍.
患者群体之间和跨时代的移植率,移植存活率和死亡审查的移植失败的比较.

主要成果:

高度敏感的患者在KAS后更频繁地接受移植 (N=1238在KAS前,N=4687在KAS后).
在KAS后,在高度敏感的接受者中,第一年的移植存活率有所改善 (HR 0.56).
虽然种族差异有所改善,但黑人患者在KAS后的高度敏感的候选人和接受者中仍然占比不大.

结论:

在高度敏感的候选人中,KAS增加了移植率,而不会影响整体结果.
在KAS后,对高度敏感的接受者来说,第一年的移植存活率有所改善.
尽管有所改善,但KAS尚未完全消除移植中的种族不平等,黑人患者的差异仍然存在.

Tissue Transplantation

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...

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...

Kidney Transplant III: Nursing Management

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...
