Serum hyaluronic acid in healthy infants and children and its value as a marker of progressive hepatobiliary disease starting in infancy.
We have established reference ranges for the concentrations of hyaluronic acid in serum from 397 infants and children and measured serum hyaluronic acid at presentation and 1 year follow-up in 37 infants who presented with hepatobiliary disease in the first 6 months of life. In health, hyaluronic acid concentrations fell progressively from median (10-90 percentile) values of 93 micrograms/l (49-153) at 1-3 months of age to 20 micrograms/l (9-40) at 2-3 years and 16 micrograms/l (6-32) at 4-18 years. In patients at presentation, the hyaluronic acid concentration was raised in 11 of 15 with biliary atresia, 6 of 11 with alpha-1 antitrypsin deficiency and 6 of 11 with cryptogenic hepatitis of infancy. One year later, the 9 patients who developed progressive liver disease showed 2-6-fold increases in hyaluronic acid concentration while no increase was observed in the 28 with undetectable or mild disease. Increases in serum hyaluronic acid concentration appeared to be a better indicator of progressive liver disease in infancy than standard laboratory tests.
