title: [Refractory anemia with ringed sideroblasts complicated with delta beta-thalassemia-like hemoglobinopathy].
abstract: A 73 year-old man suffering from marked anemia for several years admitted in our hospital. Diagnosis was immediately made of refractory anemia with ringed sideroblasts by the existence of ringed sideroblasts. Hemoglobin analysis revealed a high fetal hemoglobin, a low hemoglobin A2, a decreased beta/alpha synthetic ratio, and a decreased G gamma/A gamma synthetic ratio. This acquired hemoglobinopathy resembled delta beta-thalassemia. His anemia was remarkably improved because of the responsiveness to anabolic steroid hormone, and this abnormal globin synthetic pattern was identical as those of the normal adult. We consider this hemoglobinopathy may due to an abnormal expression of globin mRNA.
