Abstract OBJECTIVE: To evaluate the diagnostic value of measuring serum C-reactive protein (CRP) and procalcitonin (PCT) levels, within 6 hours after admission to the pediatric intensive care unit (PICU) in children with bloodstream infection (BSI)-associated sepsis and septic infection at other sites. METHODS: A retrospective analysis was performed on 30 children with a confirmed diagnosis of systemic inflammatory response syndrome who were admitted to the Shengjing Hospital of China Medical University between January 2010 and January 2012. Clinical data on serum CRP, PCT and D-dimer levels were collected within 6 hours after admission. The diagnostic values of the indices were determined by comparative analysis. RESULTS: Serum CRP and PCT levels in children with BSI-associated sepsis were significantly higher than in children with septic infection at other sites (P0.05). Serum PCT level was superior to serum CRP level in distinguishing children with BSI-associated sepsis from those with septic infection at other sites. Serum PCT level could not realistically be used for diagnosing BSI-associated sepsis when it was less than 2 ng/mL (negative predictive value: 100%), but could be reliably used when it was more than 10 ng/mL (positive predictive value: 77%). CONCLUSIONS: Serum PCT level is superior to serum CRP level in distinguishing children with BSI-associated sepsis from those with septic infection at other sites within 6 hours after admission to the PICU. Serum PCT level has a better diagnostic value for BSI-associated sepsis when it is more than 10 ng/mL.
