Preoperative Use of Romiplostim in Thrombocytopenic Patients Undergoing Cardiac Surgery.

Romiplostim has demonstrated its efficacy and good tolerance in multiple indications. If the efficacy of Romiplostim is confirmed in this population, thrombocytopenic patients will be able to undergo cardiac surgery, which is generally life-saving, without prior thrombocytopenia. Patients included in the study will be hospitalized within 15 days of the first administration of the study treatment and will be closely monitored clinically and biologically for at least 10 days after surgery. The occurrence of an adverse event can therefore be quickly detected and managed. Collectively, "Patient Blood Management" strategies are mainly focused on the management of preoperative anemia. If positive, this study will enrich the therapeutic arsenal available for optimizing patients in preparation for major surgery. As no major collective complications are expected, the collective benefit/risk ratio also appears favorable.

Clinical Efficacy of Platelet Transfusion

The aim of this study is to analyze the effect of the storage time of platelet concentrates on the occurrence of bleeding events during prophylactic platelet transfusions in patients with hematological malignancies.

Sirolimus Monotherapy in the Treatment of Antiphospholipid Antibody Related Thrombocytopenia

The goal of this clinical trial is to learn the efficacy and safety of sirolimus in the treatment of anti-phospholipid antibody associated thrombocytopenia. The patients would be followed at 2 weeks, 1 month, 3 months, and 6 months after the enrollment. The main questions it aims to answer are the differences between sirolimus and control group at below outcomes: Primary outcome: the overall response rate at 6 months Secondary outcome: the complete response rate at 6 months the partial response rate at 6 months the change of anti-phospholipid antibody titers the change of oral glucocorticoids dosage Other pre-defined outcome: the dropout rate within 6 months Participants will receive either sirolimus 1mg per day or placebo.
