It has been suggested that neonates with hyperbilirubinemia may have impaired renal function. In order to study this problem, creatinine clearance, and fractional tubular reabsorption of sodium and beta-2-microglobulin were measured in 22 jaundiced neonates with gestational ages ranging from 33 to 42 weeks and mean postnatal age of 3.9 days. These data were compared with those obtained from 23 nonjaundiced control infants matched for gestational and postnatal ages. In addition, follow-up studies of renal function were conducted in 18 of 22 study infants when serum bilirubin concentration was <11 mg/dl at a mean postnatal age of 7.6 days. No significant differences in CCr, TNa, or Tβ2M were observed. We conclude that when gestational age is ≥33 weeks, modification of current management of infants with moderate hyperbilirubinemia is unnecessary to prevent nephrotoxicity.
