Splenic infarction is a condition in which blood flow supply to the spleen is compromised, [1] leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ. [2] Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot .
Immune 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. The syndrome was first described in 1951 by R. S. Evans and colleagues. [1]
Platelets which have been bound by antibodies are taken up by macrophages in the spleen (which have Fc receptors), and so removal of the spleen reduces platelet destruction. The procedure is potentially risky in ITP cases due to the increased possibility of significant bleeding during surgery.
This is an incomplete list, which may never be able to satisfy certain standards for completion. There are many conditions of or affecting the human hematologic system—the biological system that includes plasma, platelets, leukocytes, and erythrocytes, the major components of blood and the bone marrow.

Thrombotic thrombocytopenic purpura (TTP) initially presents with a range of symptoms that may include severe thrombocytopenia (platelet count usually < 30,000/mm³), microangiopathic hemolytic anemia (evidenced by schistocytes in the blood smear), and various clinical signs such as petechiae, purpura, neurologic symptoms, myocardial ischemia ...
Reactive thrombocythemia is the most common cause of a high platelet count. It accounts for 88% to 97% of thrombocythemia cases in adults, and near 100% in children. In adults, acute infection, tissue damage, chronic inflammation and malignancy are the common causes of reactive thrombocythemia. Usually, one or more of these conditions is ...
Rheumatoid arthritis is a condition that cannot be cured but symptoms can be treated using certain medications alone or in conjunction. Due to the increased inflammatory response of the body's immune system, this condition can cause a reduction in red and white blood cells. [8]
Fostamatinib is a drug used to treat adults with low platelet count due to chronic immune thrombocytopenia (ITP) when a prior treatment for ITP has not worked well enough. Chronic immune thrombocytopenia is an autoimmune bleeding disorder where the blood doesn't clot as it should because of a low platelet count. [4] [6] [3]
