The impact of Fc gamma receptor IIa and IIIa gene polymorphisms on the therapeutic response of rituximab in Egyptian adult immune thrombocytopenic purpura.

Background In chronic immune thrombocytopenic purpura (ITP), rituximab removes the harmful autoantibodies through antibody-dependent cellular cytotoxicity. The response to rituximab in ITP is variable; the effectiveness of rituximab is influenced by the process of activation of effector fragment C gamma receptors (FcγRs). Genetic factors may affect the response to rituximab.

Serum prohepcidin level in myelodysplasia.

This study highlights the iron profile of myelodysplastic patients in the era of hepcidin and its pro-hormone, pro-hepcidin. Previous studies have focused on the anemia of chronic renal failure, thalassemia, and hemochromatosis. We determined if pro-hepcidin played a role in iron overload in patients with myelodysplasia (MDS).
