One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5] Thrombocytopenia can be contrasted with the conditions associated with an abnormally high level of platelets in the blood – thrombocythemia (when the cause is unknown), and thrombocytosis (when the cause is known). [6] [7]
D69.3: 6673: D016553 Idiopathic thrombocytopenic purpura (ITP) is the condition of having a low platelet count (thrombocytopenia) of no known cause . Recurrent thrombosis: Hemophilia: Hemophilia A: Hemophilia B: Hemophilia C: Von Willebrand disease: Antiphospholipid syndrome: Thrombocytopenia: Glanzmann's thrombasthenia: Wiskott–Aldrich syndrome
Therefore, ITP is a significant cause of fetal and neonatal immune thrombocytopenia. Approximately 10% of newborns affected by ITP will have platelet counts <50,000/uL and 1% to 2% will have a risk of intracerebral hemorrhage, comparable to that of infants with neonatal alloimmune thrombocytopenia (NAIT). [64] [65]
Pseudothrombocytopenia (PTCP) or spurious thrombocytopenia is an in-vitro sampling problem which may mislead the diagnosis towards the more critical condition of thrombocytopenia. The phenomenon may occur when the anticoagulant used while testing the blood sample causes clumping of platelets which mimics a low platelet count. [ 1 ]
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 ...
Giant platelet disorders can be further categorized: [6] caused by auto-immune disorders, for example Immune thrombocytopenic purpura (ITP), and characterized by low platelet count, but high MPV (mean platelet volume). [7] Caused by glycoprotein abnormalities: Bernard–Soulier syndrome, velocardiofacial syndrome
WASHINGTON (Reuters) -U.S. President-elect Donald Trump on Saturday named his social media platform CEO Devin Nunes to lead an intelligence advisory panel and said his former intelligence chief ...
Evans syndrome is an autoimmune disease in which an individual's immune system attacks their own red blood cells and platelets, the syndrome can include immune neutropenia. [1] [2] These immune cytopenias may occur simultaneously or sequentially.
