Study Notes
Platelet Disorders
- Grey platelet syndrome is characterized by a lighter staining peripheral zone and maintains platelet's discoid shape.
Hemostasis
- Platelet plug occurs in the primary hemostasis stage.
Thrombocytopenia
- Severe thrombocytopenia is characterized by a platelet count of < 20,000/μL.
- Autoimmune thrombocytopenia is characterized by autoantibodies attacking megakaryocytes and platelets.
Immune Thrombocytopenia
- Acute Immune Thrombocytopenia is exclusively found in children.
- Chronic Immune Thrombocytopenia is common in adult women.
Thrombotic Thrombocytopenic Purpura (TTP)
- Primary etiology of TTP is abnormal processing of von Willebrand factor.
- Characterized by microthrombi in affected organs and is different from Hemolytic Uremic syndrome.
- Associated with Escherichia coli (E. coli) infection, which leads to RBC fragmentation.
Other Conditions
- Amyloid thrombocytopenia is associated with weaker vessel walls due to perivascular amyloidosis.
- Heparin-induced thrombocytopenia (HIT) presents within the first 2 days after exposure to heparin.
- Surgical bleeding typically occurs at a platelet count of < 50,000/μL.
- Idiopathic thrombocytopenic purpura (ITP) is characterized by reduced platelet count and megakaryocytes hyperplasia in bone marrow.
