  2. Platelet transfusion - Wikipedia

    en.wikipedia.org/wiki/Platelet_transfusion

    Several studies have now assessed the benefit of using preventive platelet transfusions in adults with dengue who have profound thrombocytopenia (platelet count < 20 x 10 9 /L. [17] There is no evidence that this reduce the risk of bleeding, but there is evidence that they increase the risk of harm due to the platelet transfusion (increased ...

  3. Plateletpheresis - Wikipedia

    en.wikipedia.org/wiki/Plateletpheresis

    Platelet count increase as well as platelet survival after transfusion is related to the dose of platelets infused and to the patient's body surface area (BSA). Usually these values are less than what would be expected. Corrected platelet count increment (CCI) = platelet increment at one hr x BSA (m 2) / # platelets infused x 10 11

  4. Myelodysplastic syndrome - Wikipedia

    en.wikipedia.org/wiki/Myelodysplastic_syndrome

    Romiplostim and eltrombopag are thrombopoeitin receptor agonists which act on megakaryocytes (platelet precursor cells) to increase platelet production. They are used to increase platelet counts and have been shown to reduce the need for platelet transfusions. [ 36 ]

  5. Platelet transfusion refractoriness - Wikipedia

    en.wikipedia.org/wiki/Platelet_transfusion...

    Platelet transfusion refractoriness is the repeated failure to achieve the desired level of blood platelets in a patient following a platelet transfusion. The cause of refractoriness may be either immune or non-immune. Among immune-related refractoriness, antibodies against HLA antigens are the primary cause.

  6. Immune thrombocytopenic purpura - Wikipedia

    en.wikipedia.org/wiki/Immune_thrombocytopenic...

    Platelet transfusion alone is normally not recommended except in an emergency and is usually unsuccessful in producing a long-term platelet count increase. This is because the underlying autoimmune mechanism that is destroying the patient's platelets will also destroy donor platelets, and so platelet transfusions are not considered a long-term ...

  7. Pancytopenia - Wikipedia

    en.wikipedia.org/wiki/Pancytopenia

    Pancytopenia is a medical condition in which there is significant reduction in the number of almost all blood cells (red blood cells, white blood cells, platelets, monocytes, lymphocytes, etc.). If only two parameters from the complete blood count are low, the term bicytopenia can be used.

  8. Post-transfusion purpura - Wikipedia

    en.wikipedia.org/wiki/Post-transfusion_purpura

    Post-transfusion purpura (PTP) is a delayed adverse reaction to a blood transfusion or platelet transfusion that occurs when the body has produced alloantibodies to the allogeneic transfused platelets' antigens. These alloantibodies destroy the patient's platelets leading to thrombocytopenia, a rapid decline in platelet count. [1]

  9. Wiskott–Aldrich syndrome - Wikipedia

    en.wikipedia.org/wiki/Wiskott–Aldrich_syndrome

    Patients may require platelet transfusions when there is extreme bloodloss (such as during surgery) or for very low platelets splenectomy (removal of the spleen) may also be lifesaving. [25] However, splenectomy is generally considered palliative and is not universally recommended in WAS because it can increase the risk of life-threatening ...
