Dynamic changes and significance of serum IL-1β and sE-selectin in patients with acute pancreatitis / 中华胰腺病杂志

ABSTRACT

Objective To investigate the dynamic changes and relationship between the serum levels of IL-1 β and sE-selectin in acute pancreatitis (AP) patients, and to study the predicative value for severity of AP.Methods Forty one patients with AP were divided into severe acute pancreatitis (SAP, 19 cases) group and mild acute pancreatitis (MAP, 22 cases) group.Their serum were collected at the 1st, 3rd, 7th, and 14th day after admission and the serum concentrations of IL-1 β and sE-selectin were detected by ELISA.Another 20healthy volunteers were selected as controls.Results The serum concentration of IL-1 β in control group was ( 18.71 ±2.43)ng/L, while they were (61.18 ±7.47)ng/L, (33.03 ±5.85)ng/L, (20.73 ±4.07)ng/L in MAP group at the 1st, 3rd, 7th day;and they were (86.91 ± 13.32) rng/L, (81.35 ± 12.71) ng/L,(64.93 ±5.99)ng/L, (21.40±49.13) ng/L at the 1st, 3rd, 7th and 14th day in SAP group.The serum concentration of IL - 1β of patients with SAP were markedly higher than those with MAP and normal controls on the 1st, 3rd, 7th day (P ＜0.05) and they decreased almost to normal on the 14th day.The serum concentration of sE-selectin was ( 10.69 ± 2.51 ) ng/ml, while they were ( 41.60 ± 6.85 ) ng/ml, ( 14.90 ±3.51)ng/ml, (9.85 ±2.88)ng/ml in MAP group at the 1st, 3rd, 7th day;and they were (84.73 ±15.37)ng/ml, ( 95.65 ± 13.06 ) ng/ml, ( 39.41 ± 3.73 ) ng/ml, ( 12.25 ± 2.29 ) ng/mlon the 1st, 3rd, 7 th and 14th day.The serum concentration of sE-selectin of patients with SAP were significantly higher than those with MAP and normal controls on the 1st, 3rd, 7th day (P ＜0.05 ) and there was no significant difference between SAP and control group on the 14th day.There was a positive correlation between the serum level of IL-1 β and sE-selectin in AP on the 1 st day after admission ( r = 0.851, P ＜ 0.01 ).Conclusions The serum concentrations of IL-1 β and sE-selectin are useful for AP severity predication.
