Filter by:An observational study in which investigators will observe platelet inhibition in patients on VA ECMO acorrding to treatment with P2Y12 inhibitor.
Some of the treatments for cancer can cause platelets (the part of the blood that helps with clotting) to decrease. If they are too low, then clinicians may recommend a transfusion (getting platelets from another person added to someone else's body). This usually works to increase the person's platelets to a healthy level, but sometimes it doesn't work. This is called platelet refractoriness. This study is trying to find out whether isatuximab (the study drug) may help people with a certain type of platelet refractoriness by removing some cells in order to make platelet transfusions more effective.
Platelet transfusions are widely employed to prevent or treat bleeding episodes in patients with thrombocytopenia. Patients with bone marrow failure secondary to haematological malignancy and chemotherapy frequently receive prophylactic platelet transfusion when platelet level reaches 10x109.L-1, to avoid spontaneous major bleeding. Due to immune or nonimmune factors, platelet refractoriness may be observed and is defined as a repeated suboptimal response to platelet transfusions with lower-than-expected post-transfusion count increments. The management of patients with alloimmunization is complex and prophylactic platelet support is no longer indicated. Therefore, platelet refractoriness remains a clinically challenging complication.
