Abstract:
Objective To determine the fecal elastase-1 (FE-1) in critically ill children in order to investigate the relationships between FE-1 and trypsin,sepsis as well as the severity of the disease.Methods Totally 402 critically ill children admitted in pediatric intensive care unit (PICU) of Hunan Children' s Hospital from July 2013 to March 2014 were studied.The formed stool of patients was collected during the first 24 h after admission.Subjects were divided to 3 groups according to FE-1 concentration:> 200 μg/g for normal pancreatic exocrine function (group A,n =300),100-200 μg/g for mild to moderate exocrine pancreatic insufficiency (group B,n =52),< 100 μg/g for severe pancreatic exocrine insufficiency (group C,n =50).The analyses of the relationships between FE-1 and pancreatic enzymes,sepsis severity,shock,the number of organ dysfunction,PCIS (pediatric critically ill score),SOFA score,and APACHE Ⅱ score were carried out.Chi-squared test was used for data statistics.The median and four percentile interval were used for the measurement data of abnormal distribution or non-neat variance,the rank sum test of each two of multiple samples compared each other was used for non-parametric test,only when it was statistically significant,and the Spearman method of correlation analysis was used for correlation analysis.Results (1) There was significant difference in serum lipase between group A and group B (P < 0.01).(2) There was statistical difference in FE-1 level between sepsis group and non-sepsis group (P < 0.05).Children with sepsis were divided into three groups according to the severity of sepsis:mild sepsis group,severe sepsis group and septic shock group.There were significant difference in FE-1 level among different severities of sepsis groups and as well as non-sepsis group (P < 0.01).(3) The proportions of FE-1 in septic children of A,B and C groups in comparison with those in non-septic children of three groups were 65.79% vs.78.13%,15.79% vs.11.80%,18.42% vs.10.07%,respectively.The proportions of FE-1 in septic children of B and C groups escalated were higher than those in children without sepsis.(4) The general trend in FE-1 concentrations varied along with the severity of sepsis.There were no significant differences in FE-1 concentration between non-sepsis group and mild sepsis group,and between severe sepsis group and septic shock group,but other paired comparisons between the four groups had statistical significant (P <0.01).(5) Along with FE-1 level decreased,the number of organ dysfunction,SOFA score,APS score (This is a part of APACHE Ⅱ score and other part,CPS,is excluded) increased and PCIS score decreased (rs1 =-0.194,P =0.000; rs2 =-0.348,P =0.000; rs3 =-0.176,P =0.000; rs4 =0.185,P =0.000).Conclusions Pancreatic exocrine function damage is associated with sepsis,the pancreatic dysfunction in patients with mild sepsis may not be significant,but its incidence increases gradually with the development of sepsis or with the deterioration of the disease.
