The variation and significance of interleukin-6 and E-selectin, intercellular adhesion molecule-1 in children with sepsis / 中国小儿急救医学

ABSTRACT

Objective To investigate the variation of interleukin-6 ( IL-6 ) , vascular endothelial growth factor(VEGF),E-selectin and intercellular adhesion molecule-1(ICAM-1)in children with sepsis and the clinical significance. Methods This was a prospective and control study. Thirty-two children diagnosed as sepsis in PICU from December 2008 to December 2009 served as the sepsis group. According to whether there was a shock, sepsis group were divided into shock subgroup and no shock subgroup. Fifteen healthy children served as control group. The serum levels of IL-6,VEGF,E-selectin and ICAM-1 were detected with enzyme linked immunosorbent assay. Results The serum level of IL-6 was 65. 00(30. 49~237. 14) ng/L in shock subgroup and 48. 68(30. 25~75. 00) ng/L in no shock subgroup,which were significantly higher than that in control group[0. 80(0. 60 ~1. 00) ng/L](P<0. 05). There was no significant difference between shock subgroup and no shock subgroup. The serum levels of VEGF and E-selectin showed no significant differences among the three groups. The serum level of ICAM-1 was 998. 72(666. 93~1 526. 44) ng/ml in shock subgroup,and 925. 71(683. 53~1 225. 12) ng/ml in no shok subgroup,which were significantly high-er than that in control group[660. 59(525. 48~685. 47) ng/ml]. Compared with those who survived in sep-sis group,the serum levels of VEGF and E-selectin in the died children with sepsis showed no significant difference,but IL-6 and ICAM-1 significantly increased(P<0. 05). Conclusion IL-6 and ICAM-1 increase greatly and accentuate inflammation in septic patients,the changes of which may help to determine the prog-nosis of sepsis.
