Abstract
- OBJECTIVE: We sought to determine the clinical and histopathological factors associated with intestinal hemorrhage and its correlation with clinical outcomes in neonates with surgical necrotizing enterocolitis (NEC). METHODS: A retrospective study compared clinical and histopathology information in neonates following surgical NEC with severe hemorrhage and those with mild/moderate hemorrhagic lesions seen on resected intestine pathology. RESULTS: The infants with severe hemorrhage (Grade 3-4, 81/148, 54.7%) had significantly lower exposure to antenatal steroids (52.5 % vs 76.9 %; p = 0.004), had higher gestational age (28.5 weeks [7.14] vs. 26.58 [2.90]; p = 0.034), lost more bowel length (p = 0.045), had higher CRP levels at 2 weeks (p = 0.035), and had less intestinal failure ([30.3 % vs 52.5 %]; p = 0.014) than mild/moderate (Grade 0–2, 67/148, 45.2%) hemorrhage group. Those with severe hemorrhage had significantly higher mean inflammation score (2.67 [0.94] vs. 1.63 [0.92]; p = <0.001), higher necrosis scores (1.95 [1.28] vs. 1.49 [1.35]; p = 0.037), higher neovascularization (p = 0.01), higher fibroblasts (p = 0.023) and higher lymphocyte percentages up to 48 hours (p < 0.05) following NEC than mild/ moderate hemorrhage group. On multivariable regression, less exposure to antenatal steroids (OR 0.18 [95% CI 0.05–0.58]; p = 0.005), higher inflammation (OR 3.7 [95% CI 2.09–7.32]; p = 0.001), and lymphocyte count on the day of onset/24 hours following NEC (OR 1.06 [95% CI 1.02–1.11]; p = 0.005) were independently associated with a higher odd of severe intestinal hemorrhage. CONCLUSION: The surgical NEC infants with intestinal hemorrhage were less likely to have antenatal steroid exposure but had higher inflammation grade and lymphocyte counts following NEC onset on multivariable regression modeling.
