Plasma and erythrocyte magnesium, manganese, zinc, and plasma calcium levels in G-6-PD-deficient and normal male children.

Abstract

Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is the most common human enzymopathy in the world. Trace elements are important for normal hematopoiesis and can play a role in acute hemolytic anemia induced by G-6-PD deficiency. For this purpose, we studied two groups consisting of 10 male children who are G-6-PD-deficient and 12 age-matched normal male children to compare plasma and erythrocyte magnesium, manganese, zinc, and plasma calcium levels between G-6-PD-deficient and normal children. All assays were performed under normal conditions free of any oxidative attack that may result in hemolytic crisis in G-6-PD-deficient subjects. All parameters in each group did not differ significantly except for erythrocyte G-6-PD activities. These data show that plasma and erythrocyte trace element contents of G-6-PD-deficient subjects do not differ in normal conditions.
