Abstract:
Objective To determine the levels of blood pancreatic stone protein/ regenerating protein(PSP/reg)and to explore the value of PSP/ reg in assessing severity and predicting prognosis of sepsis with or without panc-reatic damage. Methods In this prospective study,the clinical data and blood samples to measure PSP/ reg levels in 1,3 and 7 days after admission in the Pediatric Intensive Care Unit,Hunan Children's Hospital,from the children with sepsis from September 2013 to September 2014 were collected. According to levels of pancreatic trypsin(amylase or li-pase),the children were divided into normal group,mildly elevated group(1 - 3 times),and severely elevated group (more than 3 times);based on the condition of sepsis,the children were divided into sepsis group and severe sepsis group. Chi - square test,nonparametric rank sum test,Spearman correlation and area under the receiver operating cha-racteristic curve(AUC),Kaplan - Meier survival curves were used for statistical analysis. Results (1)A total of 226 children with sepsis were included in this study,among them pancreatic trypsin was normal in 159 cases(70. 4% ), pancreatic trypsin mildly elevated in 44 cases( 19. 4% ),and pancreatic trypsin severely elevated in 23 cases (10. 2% );125 cases(55. 3% )were sepsis,and 101 cases(44. 7% ,of which 29 cases were sepsis shock)were severe sepsis.(2)The correlation between PSP/ reg and serum amylase was maximum,while PSP/ reg had some correlation with serum lipase,but there was no correlation with C - peptide,insulin,glucose.(3)When pancreatic trypsin was normal or mildly elevated,severe sepsis group had higher levels of PSP/ reg than that of sepsis group(Z = - 7. 627,- 2. 965,P =0. 000,0. 003);while pancreatic trypsin was severe elevated,there was no significant difference in PSP/ reg levels be-tween sepsis group and severe sepsis group(Z = - 0. 134,P = 0. 894).(4)The AUC of PSP/ reg and procalcitonin to assess severity of sepsis were greater than 0. 7 in the children whose pancreatic trypsin was normal or mildly elevated, and there was no significant difference between them(P ﹥ 0. 05);while the AUC of C - reactive protein and WBC were less than 0. 7.(5)PSP/ reg levels gradually increased in non - survival children in 3 and 7 days,while survival children gradually declined. The AUC of PSP/ reg to predict prognosis was 0. 775,and 60 μg/ L was viewed as the critical point, sensitivity 89% ,specificity 67% . Children with PSP/ reg levels ≤60 μg/ L had higher rate of survival than children with ﹥ 60 μg/ L(χ2 = 36. 874,P = 0. 000). Conclusions PSP/ reg is closely associated with pancreatic exocrine func-tion,but PSP/ reg still can assess severity and predict prognosis in children with sepsis and pancreatic damage.
