RESUMEN
OBJECTIVES: To determine the value of procalcitonin (PCT), high sensitivity C-reactive protein (hs-CRP) and pancreatic stone protein(PSP) in predicting the prognosis of children with sepsis. METHODS: A total of 106 hospitalized children [(4.4±1.6) year-old] with sepsis were enrolled in this study. The expressions of PTC, hs-CRP and PSP in the serum samples of the children were detected on the first day of admission to hospital. Pearson correlation analyses were performed to test the correlations between pediatric critical illness score (PCIS) and PTC, hs-CRP and PSP. Logistic regression models were established to determine factors predicting death of children. The value of PTC, hs-CRP and PSP in predicting the prognosis of children with sepsis was determined using ROC curves. RESULTS: About 32% children (34 cases) died. Higher expressions of PTC, hs-CRP and PSP were found in those who died (P<0.001). Serum PTC, hs-CRP and PSP were negatively correlated with PCIS (P<0.001). The multivariate logistic regression showed that PTC, hs-CRP and PSP were independent predictors of death in patients with sepsis (P<0.001). PTC, hs-CRP and PSP had an area under the curve (AUC) value of 0.86[ (95% confidence interval (CI), 0.78-0.92], 0.70 (95%CI, 0.61-0.79) and 0.69 (95%CI, 0.60-0.78) , respectively.The AUC value increased (P<0.001) to 0.92 (95%CI, 0.85-0.96) when the three indicators were combined (0.481×PCT+0.392×hs-CRP +0.314*PSP), with a value of less than 122.3 indicating good prognosis in 28 d. CONCLUSIONS: Serum PTC, hs-CRP and PSP can predict prognosis of children with sepsis.
