Abstract：Objective To study the value of combined measurement of intestinal fatty acid-binding protein (I-FABP) and fecal calprotectin (FC) in the diagnosis of necrotizing enterocolitis (NEC) in full-term neonates. Methods A total of 36 full-term neonates with NEC (case group) and 39 neonates without digestive system diseases (control group) were enrolled as study subjects. ELISA was used to measure the serum I-FABP level and fecal FC level, and the clinical value of I-FABP combined with FC in the diagnosis of NEC was evaluated. Results The case group had significantly higher I-FABP and FC levels than the control group (P < 0.05). In the case group, serum I-FABP level was positively correlated with fecal FC level (r=0.71, P < 0.05). In the diagnosis of NEC, I-FABP alone, FC alone, and I-FABP/FC combination had sensitivities of 83.3%, 81.5%, and 79.5%, specificities of 72.5%, 75.8%, and 86.3%, and areas under the ROC curve (AUCs) of 0.82, 0.81, and 0.88. The combined measurement showed significantly higher specificity and AUC than single measurement (P < 0.05). Conclusions Children with NEC have significant increases in I-FABP and FC levels, and there is a correlation between them. Combined measurement of I-FABP and FC can increase the specificity of the diagnosis of NEC.
