Children requiring respiratory treatment were assigned to the NVAP group, newborns who received mechanical ventilation and had neonatal respiratory distress syndrome were assigned to the first control group, and newborns with normal X-ray and electrocardiogram results but no non-pulmonary infection was assigned to the second control group. The blood and bronchoalveolar lavage fluid (BALF) sTREM-1 levels in all newborns were analyzed.Results: The acute-phase blood and BALF sTREM-1 levels were significantly higher in the NVAP group than in the first control group, and the blood sTREM-1 expression level was lower in the second control group than in the NVAP group.Conclusion: The present results suggest that sTREM-1 might be a useful biomarker for NVAP prediction in the Department of Pediatrics.Keywords: pneumonia, neonatal ventilator-associated pneumonia, soluble TREM-1, neonate, C-reactive protein
