Biomarker potential of advanced glycosylated end-products levels at
birth in premature infants with bronchopulmonary dysplasia
Abstract
Background: Bronchopulmonary dysplasia (BPD) is the most common
morbidity complicating preterm birth. The soluble receptor for advanced
glycosylated end-products (sRAGE) is impilicated in the development of
various disease such as pulmonary diseases. The objectives of this study
were to evaluate the perinatal factors associated with serum sRAGE
levels at birth and to establish whether serum sRAGE levels at birth
could be potential biomarkers for BPD. Methods: A total of 124 subjects
included 84 preterm and 40 healthy infants were included in this study.
Among 84 infants born at less than 32 weeks were categorized into BPD
neonates (n=34) and non-BPD infants (n=50). The median serum sRAGE
levels in cord blood were measured using an enzyme-linked immunosorbent
assay. Results: There were significant positive correlations between
gestational age, birth weight, and serum sRAGE levels at birth. Among
preterm infants born at less than 32 weeks, serum sRAGE levels at birth
were significantly lower in infants with BPD than without. However,
serum RAGE levels were not associated with severity of BPD. Conclusions:
Serum sRAGE levels at birth were significantly correlated with BW and
GA. Furthermore, serum sRAGE levels at birth could serve as a biomarker
for predicting BPD, but not its severity.
