Red cell ferritin and iron stores in chronic granulocytic leukemia.
Basic red cell ferritin was investigated in 28 patients with different phases of chronic granulocytic leukemia (CGL). Red cell ferritin was significantly decreased in remission after busulphan treatment and significantly elevated in the blast crisis as compared to healthy controls. Bone marrow stainable iron was decreased or absent in 86% of patients in the initial phase at the time of diagnosis and in 92% of those in remission. Red cell ferritin correlated with serum ferritin, however, serum ferritin level remained above normal range during all phases of the disease. A negative correlation between red cell ferritin and hemoglobin (Hb) (r = -0.605, p < 0.001) suggested that red cell ferritin level reflected the rate of iron utilization for heme synthesis. Decreased red cell iron stores observed in the remission may be explained by regression of dyserythropoiesis and by restoration of normal Hb synthesis after busulphan treatment. A progressive dyserythropoiesis in the blast crisis may lead to an increased red cell ferritin level.
