概括
大多数O组献血者具有高ABO抗体标位,但很少有人具有血解素. 年长的男性是理想的捐赠者,以防止血液溶解输血反应 (HTRs).
科学领域:
- 输血医学 输血医学
- 免疫学 免疫学 免疫学
- 血液银行 血液银行
背景情况:
- 来自O组血液产品的血液溶解输血反应 (HTR) 是罕见但严重的.
- 组O的捐赠者具有抗A和抗B抗体,构成HTRs的风险.
研究的目的:
- 为了确定高ABO抗体标位在O组献血者的流行率.
- 为了识别ABO抗体的免疫球蛋白 (Ig) 类 (IgM,IgG).
- 评估O组供体中血清素抗体的流行率.
主要方法:
- 来自311名O组捐献者的血在室温下测试了ABO抗体标位 (≥64被认为是高).
- 滴氨醇 (DTT) 治疗确定了IgG抗体的存在和标位.
- 用37°C的A1和B细胞悬浮剂进行了血液溶解试验.
主要成果:
- 76.5%的捐赠者表现出高的抗A和/或抗B标位 (高达256).
- 年轻的 (<40岁) 和女性捐赠者具有更高的ABO抗体标位,特别是女性的抗B (77.8%).
- 血解的发病率很低 (3.5%);年长的男性 (>50岁) 的平均标位很低.
结论:
- 大多数O组捐赠者具有高ABO抗体标位,但血解素的患病率较低.
- 年龄较大的男性 (>50岁) 是最佳的O组献血者,以尽量减少不匹配输血中HTR风险.
- 建议对年轻的女性捐赠者 (<40岁) 进行高ABO抗体标位的查,以防止向非O接受者输血强效的O组产品.

The ABO Blood Group
1.8K
The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Blood Types
17.8K
Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.

Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
