概括
血糖控制不会增加献血者血管反应 (VVR) 风险. 较高的HbA1C水平与VVR无关,这表明基于血糖状况的当前捐赠限制可能是不必要的.
科学领域:
- 血液学 血液学 血液学
- 心脏病学 心脏病学
- 内分泌学 在内分泌学.
背景情况:
- 血管道反应 (VVRs) 是献血期间常见的不良事件.
- 已知的危险因素包括年龄较小,体重较低和首次捐献者身份.
- 血糖控制对VVR风险的影响尚不清楚,一些国家限制了糖尿病患者的捐赠.
研究的目的:
- 为了研究血糖控制与献血者VVR风险之间的关联.
- 评估血红蛋白A1C (HbA1C) 水平对VVR发生的影响.
- 为有关不同血糖状况的个人提供捐赠政策的信息.
主要方法:
- 分析了391,607名献血者对HbA1C进行测试的数据.
- 捐赠者的分类为正常血糖 (HbA1C <5.7%) 和高血糖 (HbA1C ≥5.7%) 组.
- 根据性别分层的后勤回归来评估VVR风险,根据供体特征进行调整.
主要成果:
- 总共记录了9394个VVR (2.4%的发病率).
- 在女性捐赠者中,血糖水平和VVR风险之间没有发现任何关联.
- 与正常血糖男性相比,高血糖男性捐赠者表现出VVR的几率较低 (OR 0.72,95% CI:0.62-0.83).
- 年龄,种族/种族,血红蛋白和血液损失仍然是两性中VVR的重要预测因素.
结论:
- 升高的HbA1C水平与献血者的VVR风险增加无关.

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...

The ABO Blood Group
4.5K
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.
Antigens in the ABO Blood Group System
Antigens are substances that can trigger an immune response, leading to the production of antibodies. In the ABO blood group system,...

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.

Blood Types
22.2K
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.
