|Abstract:||Recognition of kernicterus as a significant contributor to newborn mortality and morbidity in G6PD deficient babies and the ease with which G6PD deficiency could be detected and kernicterus prevented by avoidance of triggers, led to the establishment of mass newborn screening for G6PD deficiency in 1965. G6PD deficient newborns are identified within a day of birth by measuring the enzyme activity in cord blood. They are then physically protected from triggers by keeping them in the hospital for the first 2 weeks of life after their parents are counseled. Enzyme activity is measured using Wong's in-house modification of the Bernstein's technique or the BM G6PD Deficiency Screening test based on the Beutler assay. Close to 1.6 million newborns, representing practically 100% of all births have been screened. Analysis of data from 22,830 newboms at the National University Hospital reveals an incidence of 1.62% in all newborns, 3.15% in males and and 0.11% in females. A distinct racial variation in the incidence of deficiency was observed in males : Chinese 3.94%, Malays 2.95% and Indians 0.66%. Intermediate deficiency was most frequently identified (1.83%) in Chinese females. With the preventive measures, the incidence of kernicterus has dropped dramatically and there has been, over the last 20 years, no reported cases of kernicterus in newborns with G6PD deficiency. We are now looking at issues like comparing different assay techniques and determining a shorter period of stay in hospital. We believe that all Asians, especially Chinese babies, should be screened for G6PD deficiency, irrespective of which country the child is born.|
