Eltrombopag for secondary failure of platelet recovery post-allogeneic hematopoietic stem cell transplant in children
Secondary failure of platelet engraftment occurs in 20% of patients undergoing allogeneic HSCT and is associated with poor outcome. Currently, there are no guidelines for treatment of late thrombocytopenia and platelet transfusion is the mainstay of treatment. Here, we describe the use of Eltrombopag to treat secondary failure of platelet recovery following HSCT in a child with severe aplastic anemia. Eltrombopag resulted in recovery of platelet count with no need for platelet transfusion support with no reported side effects. Eltrombopag may be used successfully in children with secondary failure of platelet recovery post-HSCT for SAA.
