Congenital Nonspherocytic Hemolytic Anemia, Associated with Glutathione Deficiency of the Erythrocytes

Abstract

Abstract 1. A new biochemical defect of erythrocytes is described: glutathione deficiency (reduced glutathione less than 10 per cent of the amount of reduced glutathione in normal erythrocytes). 2. The defect is associated with a clinical picture of congenital nonspherocytic hemolytic anemia which is fairly well compensated. 3. The results of a family study are consistent with an autosomal recessive pattern of inheritance. 4. Labeling with Na2Cr51O4 has a damaging effect on glutathione-deficient erythrocytes. The erythrocyte life span, as estimated by a serological method (Ashby), was markedly shortened (30 days instead of 100-120 days). 5. Red cell destruction could be increased by the administration of primaquine. 6. Secondary to the glutathione deficiency, low glyoxalase activity was observed. The glutathione-reducing capacity, glycolytic activity, and the ATP level of the abnormal red cells were found to be within the normal range. 7. On incubation of the glutathione-deficient erythrocytes in vitro with glycine-C14 and glutamine-C14, no formation of labeled glutathione could be demonstrated.
