Abstract:
Objective To study the significance of S100A12 in patients with acute pancreatitis (AP).Methods 139 patients with AP were divided into the severe acute pancreatitis (SAP) and moderate acute pancreatitis (MAP) groups.61 patients in the SAP group were further subdivided into the infection group (n =32) and the non-infection group (n =29) based on the presence/absence of secondary infection.Serum samples of these patients were collected on the 3rd,7th and 14th day after treatment.ELISA was used to determinate the S100A12,IL-1 β and IL-6 levels in serum.The area under ROC was used to evaluate the predictive role of S100A12,IL-1β,IL-6 and CRP for infection in patients with SAP.Results The S100A12,IL-1β and IL-6 levels in SAP patients were markedly higher than those in MAP patients and normal controls on the 3rd,7th and 14th day after treatment.These levels decreased toward normal range in MAP patients.They were persistently high in SAP patients after treatment for 7 days,but decreased significantly after 14 days.The serum levels of S100A12,IL-1β,IL-6 and CRP were significantly higher in the infection subgroup(647.5 ± 300.1,155.9 ±48.5,95.7 ±25.5,166.8 ±53.0) than the non-infection subgroup(249.0 ± 176.3,108.0 ± 46.1,64.0 ±38.5,117.9 ±34.9) (P ＜0.05).The sensitivity and specificity of serum S100A12 in diagnosing secondary infection in SAP were 96.8％ and 83.3％,which were higher than those of serum IL-1β,IL-6 or CRP.Conclusion The level of S100A12 was associated with systemic inflammatory response syndrome (SIRS) in AP,and it may serve as a new marker in early diagnosis of SAP and in secondary infection in SAP.
