Urinary retinol binding protein (RBP) is elevated in sick preterm infants, indicating higher sensitivity to illness compared to albumin or total protein. This finding helps in assessing neonatal health status.

Area of Science:

  • Neonatal Medicine
  • Clinical Chemistry
  • Biomarker Discovery

Background:

  • Establishing reference ranges for urinary biomarkers in neonates is crucial for diagnosing health conditions.
  • Urinary retinol binding protein (RBP), albumin, and total protein are potential indicators of kidney function and systemic illness in infants.

Purpose of the Study:

  • To determine normal ranges for urinary RBP, albumin, and total protein in healthy term and preterm neonates.
  • To investigate alterations in these urinary proteins in neonates experiencing disease states.
  • To compare the sensitivity of urinary RBP, albumin, and total protein as indicators of illness in neonates.

Main Methods:

  • Analysis of urine samples from neonates admitted to a special care baby unit.
  • Quantification of urinary retinol binding protein, albumin, and total protein concentrations.

  • Comparison of biomarker excretion relative to creatinine and clinical status.

    • Main Results:

    • Urinary RBP excretion was significantly higher in preterm infants compared to term infants.
    • Sick neonates exhibited increased urinary RBP excretion, exceeding predictions based on gestational age and creatinine levels.
    • Urinary RBP demonstrated greater sensitivity to illness than urinary albumin or total protein.

    Conclusions:

    • Urinary RBP is a sensitive biomarker for detecting illness in neonates, particularly in preterm infants.
    • Elevated urinary RBP in sick neonates suggests a potential role in monitoring disease severity and progression.
    • Further research can explore the clinical utility of urinary RBP in neonatal intensive care settings.
