Insights
This study identifies key risk factors for neonatal hyperbilirubinemia in breast-fed infants. Combining third-day bilirubin levels and UGT1A1 gene variants effectively predicts jaundice risk.
Area of Science:
- Neonatal Medicine
- Pediatric Gastroenterology
- Genetics
Background:
- Neonatal hyperbilirubinemia poses a significant health risk to term breast-fed infants.
- Early identification of at-risk infants is crucial for timely intervention and prevention of complications.
Purpose of the Study:
- To develop a predictive model for identifying term breast-fed infants at risk of significant neonatal hyperbilirubinemia.
- To evaluate specific clinical and genetic factors associated with hyperbilirubinemia development.
Main Methods:
- A prospective study involving 240 exclusively breast-fed term neonates.
- Investigated factors including birth weight, delivery mode, G6PD deficiency, predischarge bilirubin, and UGT1A1/SLCO1B1 gene variants.
- Defined significant hyperbilirubinemia based on American Academy of Pediatrics phototherapy guidelines.
Main Results:
- 10.8% of infants developed significant hyperbilirubinemia.
- Predischarge total serum bilirubin (day 3) and variant UGT1A1 gene (nucleotide 211) were significant risk factors.
- The predictive model demonstrated high accuracy (ROC curve AUC = 0.964).
Conclusions:
- A combination of third-day total serum bilirubin and the variant UGT1A1 gene at nucleotide 211 effectively predicts hyperbilirubinemia in term breast-fed infants.
- This model can aid in early risk stratification and management of neonatal jaundice.
Background:
The aim of this study was to establish a model to identify term breast-fed infants who are at risk of developing significant neonatal hyperbilirubinemia.
Methods:
A prospective study was designed to investigate the effects of birth weight, mode of delivery, cephalohematoma, glucose-6-phosphate dehydrogenase (G6PD) deficiency, predischarge total serum bilirubin, variant uridine 5'diphospho-glucuronosyltransferase 1A1 (UGT1A1) gene, and hepatic solute carrier organic anion transporter 1B1 (SLCO1B1) gene on significant hyperbilirubinemia in term breast-fed neonates. Significant hyperbilirubinemia was defined as a bilirubin level exceeding the hour-specific phototherapy treatment threshold recommended by the American Academy of Pediatrics in 2004.
Results:
Of 240 exclusively breast-fed term neonates, 26 (10.8%) had significant hyperbilirubinemia. The predischarge total serum bilirubin on the third day (odds ratio (OR) = 2.63; 95% confidence interval (CI): 1.87-3.70; P < 0.001) and the variant UGT1A1 gene at nucleotide 211 (OR = 5.00; 95% CI: 1.08-23.03; P < 0.05) were significant risk factors. The area under the receiver operating characteristic (ROC) curve of the predictive probability was 0.964 (95% CI: 0.932-0.984; P < 0.0001).
Conclusion:
Combining the total serum bilirubin on the third day and the variant UGT1A1 gene at nucleotide 211 can predict hyperbilirubinemia well in term breast-fed infants.
