概括
人类白细胞抗原 (HLA) 敏感化风险在移植失败后增加. 更多的HLA不匹配,特别是在HLA-DR和HLA-A位点,与血液透析 (HD) 患者更高的敏感性有关.
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
- 移植 移植 移植 移植
背景情况:
- 脏移植失败需要重返透析,这段时间患者可以产生人类白细胞抗原 (HLA) 敏感性.
- 导致移植后失去HLA敏感性的因素尚不清楚,缺乏建立的共识.
- 了解这些因素对于在移植后等待或接受透析的患者的管理至关重要.
研究的目的:
- 鉴定移植衰竭和恢复血液透析 (HD) 后患者中HLA敏感化风险增加相关的因素.
- 调查HLA不匹配和这种患者群体中抗HLA抗体的发展之间的关系.
主要方法:
- 进行了一项回顾性观察性研究,收集人口统计和移植相关数据.
- 数据包括人类白细胞抗原 (HLA) 不匹配,计算面板反应性抗体百分比的变化以及免疫抑制撤回计划.
- 患者的分析是基于1年后抗HLA抗体的发展,在HD.
主要成果:
- 与没有抗HLA抗体的患者相比,开发抗HLA抗体的患者显示出总HLA不匹配,HLA-DR不匹配和HLA-A不匹配的数量显著增加.
- 在分析具有高计算面板反应性抗体百分比的患者时,HLA不匹配的这些差异更加明显.
- 停止免疫抑制治疗的时间似乎没有影响HLA敏感性.
结论:
- 人类白细胞抗原 (HLA) 不匹配是影响脏移植衰竭后HLA敏感性的重要因素,特别是在血液透析 (HD) 的第一年.
- 建议在预计多次移植的患者中优先考虑HLA匹配.
- 意识到HLA不匹配对HD期间敏感化的影响对于患者管理至关重要.

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...

Tissue Transplantation
337
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...

Hypersensitivities
501
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Heart Failure Drugs: Diuretics
338
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Bone Marrow Sampling and Transplants
279
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
