Immune-mediated hemolytic anemia (IMHA) is a type of anemia caused by the destruction of red blood cells by the body’s own immune system. IMHA is a serious condition that can lead to life-threatening complications. This article will discuss the types of IMHA and their causes.
Primary IMHA
Primary IMHA is an autoimmune disorder in which the body’s own immune system mistakenly attacks and destroys red blood cells. This type of IMHA is usually seen in adults and can be caused by a variety of conditions, including certain drugs, infections, and underlying medical conditions.
Secondary IMHA
Secondary IMHA is caused by an underlying disorder or condition. This type of IMHA is seen more commonly in children and can be associated with bacterial or viral infections, autoimmune diseases, or certain drugs.
Paroxysmal Nocturnal Hemoglobinuria (PNH)
PNH is an acquired disorder in which the body’s own immune system mistakenly attacks and destroys red blood cells. This type of IMHA is usually seen in adults and can be caused by a variety of conditions, including certain drugs, infections, and underlying medical conditions.
Autoimmune Hemolytic Anemia (AIHA)
AIHA is an autoimmune disorder in which the body’s own immune system mistakenly attacks and destroys red blood cells. This type of IMHA is usually seen in adults and can be caused by a variety of conditions, including certain drugs, infections, and underlying medical conditions.
