ITGA2B and autoimmune disease: These events are thought to be due to autoantibodies that target platelet external glycoproteins such as GPIb/IX and GPIIb/IIIa.[10,11] Secondary ITP is caused by other conditions, such as autoimmune disease, infection, cancer, or medication.[11] Specific autoimmune diseases include lymphoproliferative diseases, immunodeficiency diseases, and chronic infections,[12] and certain drugs can also cause secondary ITP.[13,14] Moreover, COVID infection was reported as a potential secondary cause of ITP.[15–17]
