Background and aim: Systemic inflammatory response syndrome (SIRS) has to do with how the body reacts to injury. Herein, we analyzed the clinical features of acute pancreatitis (AP) in children with SIRS complication and investigated the role of SIRS score combined with C-reactive protein (CRP) level in assessing AP severity in children.
Methods: This retrospective cohort study involved 111 children hospitalized with AP at the Children's Hospital of Zhejiang University School of Medicine between January 2012 and August 2017. Presence of SIRS, demographic data, clinical information and laboratory test results on admission were statistically examined.
Results: Out of the 111 AP cases, 45 were diagnosed with SIRS. Differences in CRP, interleukin-6 (IL-6), age, temperature, heart rate (HR), white blood cell (WBC), neutrophil count (NC), body mass index (BMI), duration of onset of disease symptoms as well as cases requiring intensive care unit (ICU) treatment were significantly higher in patients with SIRS than those without SIRS (p < .01 or p < .05). Logistic regression analyses evinced two independent risk factors for SIRS to be coexisted diseases (odds ratio (OR) = 4.871, p = .02) and fever (OR = 3.56, p = .007). SIRS was an independent predictor for AP severity (OR = 10.820, p = .005). The optimal cut-off value of CRP was 27.5 mg/L for severe AP classification according to receiver operating characteristic (ROC) (area under curve was 0.733).
Conclusion: Amalgamation of SIRS criterion with CRP level potentially plays an important role in assessing AP severity in children.
