hematology

BackgroundSevere aplastic anemia (SAA) is a life-threatening bone marrow failure disorder. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an established curative treatment for pediatric patients with SAA. Busulfan, a key component of conditioning regimens, has a narrow therapeutic index and marked interindividual pharmacokinetic variability. However, the impact of different fir…

Immune thrombotic thrombocytopenic purpura (iTTP) is an autoimmune thrombotic microangiopathy caused by antibody-mediated deficiency of the plasma metalloprotease ADAMTS13. Therapeutic antibodies that target antibody-producing B-cells via the CD20 surface receptor protein to prevent disease exacerbation and relapse have become part of the standard of care of patients with iTTP. However, clinical …

Thrombosis associated with HIF-PH inhibitor therapy has become a major concern. While elevated transferrin (Tf) levels were previously thought to be the cause, recent findings suggest that Tf may actually inhibit thrombus formation. I propose a new hypothesis based on my own theory.

Platelet-activating antibodies against platelet factor 4 (PF4) cause highly prothrombotic disorders with reduced platelet counts. In heparin-induced thrombocytopenia (HIT), these antibodies bind PF4–heparin complexes, causing heparin-dependent platelet activation. Less common autoimmune and spontaneous HIT variants that are triggered by heparin and nonpharmacologic polyanions, respectively, have …

For 50 consecutive years, the University of North Carolina Division of Hematology has received funding through a National Institutes of Health (NIH) T32 training grant. The milestone reflects five decades of investment in training physician-scientists and researchers who have gone on to advance the field of hematology through careers in academic medicine and at the bench. Originally awarded in Ju…
