Article Title: The relationship between reticulated platelets, intestinal alkaline phosphatase, and necrotizing enterocolitis
Abstract: BACKGROUND: Necrotizing enterocolitis (NEC) affects up to 10% of extremely-low-birthweight infants, with a 30% mortality rate. Currently, no biomarker reliably facilitates early diagnosis. Since thrombocytopenia and bowel ischemia are consistent findings in advanced NEC, we prospectively investigated two potential biomarkers: reticulated platelets (RP) and intestinal alkaline phosphatase (iAP). METHODS: Infants born 0 U/L) in at least one sample before onset. Infants with "low" RP were significantly more likely to develop NEC [HR=11.0 (1.4-83); P=0.02]. Infants with "high" iAP were at increased risk for NEC, although not significant [HR=5.2 (0.7-42); P=0.12]. Median iAP levels were significantly higher at week 4 preceding the average time to NEC onset by one week (35.7+/-17.3days; P=0.02). CONCLUSION: Decreased RP serves as a sensitive marker for NEC onset, thereby enabling early preventative strategies. iAP overexpression may signal NEC development.
