Open Access Abstract Heme oxygenase-1 HO-1 an inducible heme-degrading enzyme is expressed by macrophages and endothelial cells in response to various stresses. Because ferritin synthesis is stimulated by Fe2 which is a product of heme degradation we examined the relation between HO-1 and ferritin levels in the serum of patients with hemophagocytic syndrome HPS adultonset Still s disease ASD and other diseases that may cause hyperferritinemia. Seven patients with HPS 10 with ASD 73 with other rheumatic diseases 20 with liver diseases 10 recipients of repeated blood transfusion because of hematological disorders and 22 healthy volunteers were enrolled. Serum HO-1 and ferritin levels were determined by ELISA. Expression of HO-1 mRNA and protein by peripheral .
