In this study, 14 children with G-6-PD deficiency aged 5 to 20 years and 14 healthy controls of the same age group were studied. Erythrocytic G-6-PD(quantitative and qualitatively), erythrocytic GSH-Px (quantitatively) and erythrocytic GSH-Rx activities (qualitatively) and serum vitamin E levels(with HPLC) have been determined.

G-6-PD activity was found to be 2.84±0.91 U/g Hb in the G-6-PD deficient group and 9.32±3.40 U/g Hb in the control group(p<0.05).

Mean serum vit E level was 5.34±0.99 μg/mL in the G-6-PD deficient group and 7.11±1.67 μg/mL in the healthy controls(p<0.05).

Erythrocytic GSH-Px activity was 3.24±0.90 U/g Hb in the G-6-PD deficient cases and 9.09±2.35 U/g Hb in the controls.

GSH-Rx activity was below normal in all G-6-PD deficient cases; in contrary, GSH-Rx was normal in controls.
