Giant platelet disorders, also known as macrothrombocytopenia, are rare disorders featuring abnormally large platelets, thrombocytopenia and a tendency to bleeding. Giant platelets cannot stick adequately to injured blood vessel walls, resulting in abnormal bleeding when injured.
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]
In terms of diagnosis Bernard–Soulier syndrome is characterized by prolonged bleeding time, thrombocytopenia, increased megakaryocytes, and enlarged platelets, Bernard–Soulier syndrome is associated with quantitative or qualitative defects of the platelet glycoprotein complex GPIb/V/IX. The degree of thrombocytopenia may be estimated ...
It is not yet known why inclusion bodies are not present in platelets, monocytes, and lymphocytes, or how giant platelets are formed. MYH9 is also found to be responsible for several related disorders with macrothrombocytopenia and leukocyte inclusions, including Sebastian, Fechtner, and Epstein syndromes, which feature deafness, nephritis, and ...
Harris platelet syndrome, previously known as asymptomatic constitutional macrothrombocytopenia, is the most common inherited giant platelet disorder in the Indian subcontinent. It is characterized by a functional thrombocytopenia due to the presence of giant platelet cells.
Platelet transfusion is contraindicated in thrombotic thrombocytopenic purpura (TTP), as it fuels the coagulopathy. Platelet transfusion is generally ineffective, and thus contraindicated, for prophylaxis in immune thrombocytopenia (ITP), because the transfused platelets are immediately cleared; however, it is indicated to treat bleeding. [70]
Unlike ITP, the platelet count in gestational thrombocytopenia rarely goes below 100,000, and a platelet count below 80,000 is even more rare (seen in less than 0.1% of cases of gestational thrombocytopenia). Also unlike ITP, gestational thrombocytopenia is not a cause of neonatal or maternal bleeding, or neonatal thrombocytopenia. [63]
Glanzmann's thrombasthenia is an abnormality of the platelets. [2] It is an extremely rare coagulopathy (bleeding disorder due to a blood abnormality), in which the platelets contain defective or low levels of glycoprotein IIb/IIIa (GpIIb/IIIa), which is a receptor for fibrinogen.
