Abstract
ObjectiveTo explore the value of combined detection of high mobility group protein B1 (HMGB1) and intestinal fatty acid binding protein (I-FABP) in the diagnosis of necrotizing enterocolitis (NEC) in neonates.
MethodsFrom July 2016 to July 2018, one hundred and nineteen NEC neonators (NEC group) admitted to Northwest Women and Children’s Hospital and 30 non-NEC neonators during the same period (control group) were selected. Enzyme linked immunosorbent assay (ELISA) was used to detect the protein expression levels of HMGB1 in stool samples and I-FABP protein expression levels in serum. ROC curve was used to analyze the diagnostic efficacy of single test and combined test for NEC.
ResultsThe expression levels of HMGB1 and I-FABP in children with Bell stage Ⅲ NEC were significantly higher than those in children with stage and Ⅱ NEC (P<0.05), the protein level showed a gradual upward trend with the aggravation of the disease. The levels of HMGB1 and I-FABP protein in NEC group were significantly higher than those in control group (P<0.05). The sensitivity, specificity and area under ROC curve were 89.60%, 86.50% and 0.985 (P<0.01), respectively, and the diagnostic efficiency of the two combined indicators was significantly higher (P<0.05).
ConclusionsThe combined detection of HMGB1 and I-FABP has high sensitivity and specificity in the diagnosis of neonatal NEC. Real-time dynamic determination of HMGB1 and I-FABP is helpful for early screening and treatment of suspected NEC neonates and judgment of disease.
