PHYSIOLOGIC HYPERBILIRUBINEMIA AND HEMOLYSIS OF ERYTHROCYTES BY HYDROGEN PEROXIDE SOLUTION IN THE NEWBORN: INVESTIGATION OF A POSSIBLE RELATIONSHIP

Forty-three full-term infants have been studied with respect to hemolysis of erythrocytes in solutions of hydrogen peroxide and concentrations of bilirubin in the serum.

Mean values for concentration of bilirubin in the serum and percentage of hemolysis followed similar patterns in the first few days of life. However, statistical analysis of the data in individual cases showed no significant correlation between the degree of hemolysis in solutions of hydrogen peroxide and the concentrations of bilirubin in the serum.

Administration of vitamin E prevented an increase in hemolysis of erythrocytes in solutions of hydrogen peroxide but failed to produce any significant change in concentrations of bilirubin as compared with the control group.

The evidence suggests that the relative deficiency of vitamin E which exists in most newborn infants does not play a part in the causation or maintenance of physiologic hyperbilirubinemia.

The clinical significance of increased hemolysis of the erythrocytes of the newborn infant in solutions of hydrogen peroxide remains a mystery. Possible approaches to the clarification of this problem are suggested.
