  • Title: Increase in bilirubin binding to albumin with correction of neonatal acidosis.
    Author: Kozuki K, Oh W, Widness J, Cashore WJ.
    Journal: Acta Paediatr Scand; 1979 Mar; 68(2):213-7. PubMed ID: 33528.
    Abstract:
    Twenty-six serial measurements of free bilirubin concentration and apparent association constant of bilirubin for albumin (Ka) at a bilirubin: albumin molar ratio of 0.8 were performed and compared with baseline values in 11 newborn infants with acidosis before treatment and during recovery from acidosis. When arterial pH was corrected from 7.12 +/- 0.02 (Mean +/- S.EM.) to 7.34 +/- 0.02, there was a significant decrease in serum free bilirubin concentration and a significant increase in the Ka at molar ratio 0.8. The data offer in vivo evidence that correction of acidosis in the neonate results in an improvement of the apparent bilirubin binding affinity of albumin.
