概括
遗传性阿尔法酸血症 (HαT) 患者患有诸如乳病和全身性红斑狼 (SLE) 等自身免疫性疾病的患病率较高. 这项研究突出显示,与普通人群相比,HαT患者的自身抗体阳性和药物过敏性增加.
科学领域:
- 免疫学 免疫学 免疫学
- 遗传学 是一个遗传学.

主要方法:
- 在第三级过敏诊所对101名具有阳性基因定型的HαT患者的回顾性图表审查.
- 提取人口统计数据,自身免疫病史和自身抗体血清学.
- 将HαT队列数据与文献数据进行比较:一般人群中自身免疫标记物的流行率.
主要成果:
- 与普通人群 (0.8%) 相比,HαT患者表现出正抗组织转质胺酶 (tTG) 抗体的显著更高的患病率 (4.9%).
- 与一般人群相比,HαT队列中乳病 (5%) 和全身性红斑狼 (SLE) (1%) 的患病率也显著增加.
- 超过一半的HαT患者 (52.5%) 报告了药物过敏史.
结论:
- 遗传性alpha-tryptasemia (HαT) 与乳病,SLE和阳性抗tTG血清学的患病率增加有关.

Autoimmune Disorders
390
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Blood Typing
1.1K
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.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target...

Blood Transfusion and Agglutination
10.7K
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
17.4K
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.
