Study Summary

This trial is testing whether transfusing platelets more slowly than the standard rate can be more effective for people with PTR. Blood will be drawn before and after transfusions to study the effects.

Who is the study for?
Adults aged 18-100 with very low platelet counts who need a transfusion and have platelet transfusion refractoriness (PTR), meaning standard transfusions don't increase their platelet count enough. They must understand the study and agree to participate. Excluded are those responsive to certain immune therapies, under 18, unable to consent, with autoimmune thrombocytopenia or pregnant women.Check my eligibility
What is being tested?
The trial is testing if giving platelets more slowly than usual can help people whose bodies don't respond well to normal transfusions. Participants will receive two types of transfusions: one over an hour (SHORT) and another over four hours (LONG). They'll be randomly assigned an order for these treatments.See study design
What are the potential side effects?
Potential side effects from the different rates of platelet transfusion aren't specified in detail but may include reactions similar to regular blood product transfusions such as fever, allergic reactions, or infection at the injection site.
