Autoimmune Disorders01:29

Autoimmune Disorders

618
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 Transfusion and Agglutination

11.1K
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 Typing01:10

Blood Typing

1.3K
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

678
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...

Disorders of Erythrocytes01:27

Disorders of Erythrocytes

1.1K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Area of Science:

  • Hematology
  • Immunology
  • Internal Medicine

Background:

  • Autoimmune haemolytic anaemias (AIHA) are acquired hematological disorders.
  • Characterized by autoantibody-mediated erythrocyte destruction.
  • Classified by etiology (primary/secondary) and antibody type (warm/cold AIHA).

Purpose of the Study:

  • To review current management strategies for AIHA.
  • To highlight emerging therapeutic options.
  • To discuss the role of novel drugs in refractory cases.

Main Methods:

  • Review of current literature on AIHA management.
  • Analysis of recent study results for established and novel therapies.
  • Focus on treatment protocols for warm AIHA (w-AIHA) and cold AIHA (c-AIHA).

Main Results:

  • Glucocorticoids remain the primary treatment for w-AIHA.
  • Early rituximab addition shows promise in w-AIHA.
  • Rituximab is a key therapy for primary c-AIHA, often combined with chemotherapy.

Conclusions:

  • Established treatments for AIHA include glucocorticoids and rituximab.
  • Novel therapies such as Syk inhibitors, anti-FcRn Ig, and complement inhibitors are under development.
  • These new drugs offer potential for improved management of refractory or relapsed AIHA cases.
