研究的目的
- 这是一个诊断复杂的严重溶血性贫血病例与异常的自身抗体.
- 讨论诊断自身免疫性疾病的挑战,特别是在资源有限的环境中.
- 强调在临床实践中仔细解释罕见的自身抗体的重要性.
主要方法
- 一个45岁的妇女患有严重的贫血和血液溶解.
- 实验室检测显示抗PO,抗Ku和抗U1snRNP抗体呈阳性.
- 对SLE的诊断标准 (EULAR/ACR 2019,SLICC 2012) 进行了评估,通过间接免疫光 (IIF) 检测出无核抗体 (ANA).
主要成果
- 患者出现严重的贫血 (血红蛋白: 2. 9 g/ dL) 和血液溶解的证据.

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...
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...
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.

The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
The Rhesus Antigen and Blood Groups
The Rh antigen is a protein found on the surface of red blood cells (RBCs) in most individuals. Its presence or absence classifies a person's blood type as Rh-positive or Rh-negative. For instance, if someone with blood type A has the Rh antigen, they are classified as A positive (A+). Without the Rh antigen, their blood group is A...
Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...
