Overview
Pathogenesis
Evans syndrome is an autoimmune disease in which an individual's antibodies attack their own red blood cells and platelets.[1] Both of these events may occur simultaneously or one may follow on from the other.[2]
- Its overall pathology resembles a combination of autoimmune hemolytic anemia and idiopathic thrombocytopenic purpura.[1] Autoimmune hemolytic anemia is a condition in which the red blood cells that normally carry oxygen and carbon dioxide are destroyed by an autoimmune process. Idiopathic thrombocytopenic purpura is a condition in which platelets are destroyed by an autoimmune process. Platelets are a component of blood that contribute to the formation of blood clots in the body to prevent bleeding.
