Abstract:
Objective To study the changes and significance of serum intestinal fatty acid binding protein (IFABP) in children with traumatic brain injury(TBI) complicaled with acute gastrointestinal injury (AGI). Methods A total of 95 children suffering from TBI hospitalized in the PICU of the First Affiliated Hospital of Zhengzhou University from January 2017 to March 2018 were enrolled in the study. According to the modified Glasgow coma score combined with clinical classification criteria for acute closed head injury, the cases were devided into mild(43 cases),moderate (23 cases),and severe(29 cases). Children were gra-ded according to AGI (AGI Ⅰ42 cases,AGI Ⅱ 30 cases,AGI Ⅲ 13 cases,and AGI Ⅳ 10 cases). Thirty healthy children who underwent physical examination at outpatient service were enrolled as the control group. Blood samples were collected at the time of admission and on the 3rd day after admission. Serum IFABP was detected by ELISA,and the differences of serum IFABP concentrations were compared among groups. The correlations between IFABP with TBI classification and AGI grade were analyzed. The receiver operating characteristic (ROC) curve was drawn,and the predictive values of IFABP for the diagnosis of children with TBI complicated with AGI were evaluated. Results On the day of admission,the serum levels of IFABP in mild,moderate and severe brain injury group were significantly higher than that in control group (all P <0. 01). And serum IFABP concentration gradually increased with the increase of brain injury (all P < 0. 01).Serum IFABP levels in children with AGI grade Ⅰto Ⅳ were significantly higher than those in control group (all P < 0. 01). The levels of serum IFABP also increased with the increase of AGI level (all P < 0. 01). The concentration of serum IFABP was positively correlated with the grade of TBI and AGI (rs = 0. 82,P < 0. 01;rs = 0. 70,P < 0. 01). In each group,the levels of serum IFABP on the 3rd day after admission were lower than those on admission (all P < 0. 01). The ROC curve analysis showed that serum IFABP was of high diag-nostic value in children with TBI complicated with AGI,and the area under the ROC curve was 0. 88. When the cutoff value of IFABP was 431. 36 ng/ L,the sensitivity and specificity were 71. 61％ and 90. 00％ ,re-spectively. Conclusion Serum IFABP can be used as a sensitive indicator for the early diagnosis and disease assessment in children with TBI complicated with gastrointestinal dysfunction.
