Leucocyte glucose-6-phosphate dehydrogenase (G-6-PD) activity in G-6-PD deficient Chinese.
The activity of glucose-6-phosphate dehydrogenase (G-6-PD) in leucocytes was studied for erythrocyte G-6-PD deficiency using 49 hemizygous males, 16 heterozygous females, and 19 normal controls. The mean G-6-PD activity in leucocytes of the affected neonates (9.2 +/- 5.4 units) and the children (11.2 +/- 5.3 units) were significantly lower than those of normal newborns (22.9 +/- 5.1 units, P less than 0.01). Seventy percent of the effected newborns and 58% of the children with G-6-PD deficiency had the leucocyte enzyme activity of less than 13 IU/10(9)WBC. The leucocyte enzyme activity (14.6 +/- 8.6 units) of 16 heterozygous G-6-PD deficient mothers was also lower than that of normal controls (23.1 +/- 7.0 units). The present study thus concludes that, in G-6-PD deficient Chinese, the enzyme defect is demonstrable not only in erythrocytes but also in leucocytes.
