| Outline of Final Research Achievements |
Although the pathogenesis of bronchopulmonary dysplasia (BPD) remains unclear, the development of BPD has been reported to be associated with pulmonary inflammation. To search for the correlation between BPD and serum neutrophil gelatinase-associated lipocalin (NGAL), serum levels of NGAL at birth were measured and assessed in the association of BPD. The median NGAL levels and neutrophil counts at birth in BPD group (n=16) were higher than non-BPD group (n=20) (p=0.012). Higher NGAL levels at birth showed a significant association with BPD (p<0.01). The serum levels of NGAL at birth might be an early predictive marker for BPD in preterm infants. We then evaluated the relationship among the hematological features, clinical course and radiological severity (chest CT scoring) of BPD infants (n=73). SGA and sustained inflammation until 28 day of life were associated with aggravation of BPD.
