Neonatal jaundice and glucose-6-phosphate dehydrogenase deficiency in Basrah.

In a study on a group of 186 newborn babies presenting with jaundice, erythrocyte glucose-6-phosphate dehydrogenase (G6PD) deficiency was detected in 95 (51%) of the patients. The incidence of severe hyperbilirubinaemia appeared to be much greater in G6PD-deficient infants (46%) than in infants who did not have the red cell defect (15%). No change was found in this association when ABO incompatibility was excluded. Phototherapy did not reduce the need for exchange transfusion, which was necessary in 27 babies. Eight babies developed kernicterus and one died. Early detection of G6PD deficiency and close surveillance of the affected newborns may be important in reducing the risk of severe neonatal jaundice and kernicterus associated with G6PD deficiency in Basrah.
