Post-transfusion purpura (PTP) is a rare yet serious disease characterized by severe thrombocytopenia occurring after a blood transfusion. It is caused by alloimmunization against platelet antigens, anti-HPA-1a being the most frequent antibody. No platelet transfusions were needed.
Also to know is, can blood transfusion cause low platelets?
Surgery to treat cancer may lead to blood loss and a need for red blood cell or platelet transfusions. Most chemotherapy drugs affect cells in the bone marrow. This commonly leads to low blood cell counts, and can sometimes put a person at risk for life-threatening infections or bleeding.
Likewise, what is the cause of post transfusion purpura? It occurs after transfusion of any platelet-containing product (red blood cells or platelets) causing acute profound thrombocytopenia [1]. It is caused by alloimmunization against platelet antigens, anti-human platelet antigen-1a (HPA-1a) being the most frequent antibody involved [2].
Also, what are the side effects of platelet transfusion?
Common side effects of platelets include:
- Hemolytic transfusion reactions.
- Febrile non-hemolytic reactions.
- Allergic reactions ranging from hives to severe (anaphylaxis)
- Septic reactions.
- Transfusion Related Acute Lung Injury (TRALI)
- Circulatory overload.
- Transfusion associated graft versus host disease.
How much do platelets increase with transfusion?
Thrombocytopenia. Typical dosing for an adult is a pool of 6 whole blood derived (sometimes referred to as random donor) platelets or one apheresis platelet. This is expected to raise the platelet count by 30,000-60,000/uL in a 70 kg patient.
Is 70 a low platelet count?
A normal platelet count ranges from 150,000 to 350,000. It's important to have enough platelets in your blood. If the number of platelets is too low, excessive bleeding can occur.

|---|---|---|
| "Delayed" hemolytic reaction | Within 3 to 7 days Up to weeks after the transfusion | Low-grade fever, mild jaundice (yellowing of the skin and whites of the eyes), decrease in hematocrit, chills, chest pain, back pain, nausea |
How many platelet transfusions can you have?
The usual doses have been in the range of 3 × 1011 to 5 × 1011 platelets per transfusion but one-quarter to one-half of these doses has been shown to be equivalent in preventing bleeding in a recent but as yet unpublished large national randomized trial (Prophylactic Platelet Dose on Transfusion Outcomes, or PLADO) [4]Can having a blood transfusion change you?
This study shows that patients might feel that transfusions could modify their behavior or values and that certain personality traits of the donor could be transmitted. However, there is little scientific evaluation of possible changes in behavior after a transfusion.Why do you have a blood transfusion?

Platelet transfusion, also known as platelet concentrate, is used to prevent or treat bleeding in people with either a low platelet count or poor platelet function. Often this occurs in people receiving cancer chemotherapy. Platelets can be produced either from whole blood or by apheresis.Do platelet transfusions need to be cross matched?
A cross-match is usually not needed for a platelet or plasma transfusion unless the platelets look like they could contain some red blood cells.How fast can you transfuse platelets?
| Blood component | Notes on administration |
|---|---|
| Platelets | Usually transfused over 30–60 minutes per ATD. |
