Differential Diagnosis of Thrombocytopenia in Hematopoietic Stem Cell Transplant Patients

Thrombocytopenia has remained a major concern in post-haematopoietic stem cell transplant patients. It is a strong negative indicator for survival and is often seen in patients with advanced acute and chronic Graft versus host disease (GVHD). The pathogenesis of thrombocytopenia varies from impaired thrombopoiesis to increased turnover of platelets. The dose of CD34+ cells and that of megakaryocyte specific lineage cells (CD34+/CD41+ and CD34+/CD61+) has a positive effect on thrombopoiesis. Conditions like bone marrow fibrosis, CMV infection and ganciclovir administration affect the bone marrow environment leading to ineffective thrombopoiesis. Increased destruction of platelets is seen with GVHD, drugs, infections, thrombotic microangiopathy and platelet refractoriness due to alloimmunization. The management of thrombocytopenia includes treating the underlying conditions and supportive care with platelet transfusion.
