Abstract

Disease indicators for sepsis and analysis of sepsis treatment in children using the continuous blood purification technique

We analyzed disease severity, inflammation markers, and dynamic changes in cartilage glycoprotein 39 (YKL-40) and Creactive protein (CRP) levels in children with sepsis before and after treatment with continuous blood purification (CBP). Study participants were 30 children with severe sepsis who were cured from the disease (experimental group) in the Children’s Serious Disease Center of Inner Mongolia People’s Hospital between June 2012 and October 2013. Symptomatic CBP treatment was performed after disease severity scoring. Interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), YKL-40, and CRP levels were tested 0, 12, 24, and 48 h after CBP treatment. YKL-40 mRNA expression in whole blood was determined biochemically, and its expression in peripheral blood was determined with an immunochemical method. We found a significant difference in disease severity scores before and 48 h after CBP treatment (P < 0.05). IL- 6, TNF-α, YKL-40, and CRP levels in children with sepsis at 12, 24, and 48 h after CBP treatment significantly differed from those before treatment (P < 0.05). The relative expression of YKL-40 mRNA in the experimental group before CBP treatment significantly increased from that of the control group (P < 0.05). We found a positive correlation between IL-6, TNF-α, YKL-40, and CRP levels 48 h after CBP treatment. In conclusion, CBP is an effective treatment strategy for pediatric sepsis. YKL-40 and CRP can be used to evaluate the effects of sepsis treatment.
