ObjectiveTo investigate the changes of serum soluble CD 163 (sCD 163) level, to assess the severity of critical illness and to evaluate the immune status of sepsis or severe sepsis in children.MethodA prospective study was conducted. The sCD 163 was determined in 50 cases with sepsis or severe sepsis in pediatric intensive care unit (PICU) and 23 cases of age- and gender-matched healthy children were enrolled as control during the period from April 2010 to March 2011. Double-antibody sandwich ELISA was used for sCD 163 measurement. The relationship with sCD 163 level and disease severity score (pediatric critical illness score, PCIS; and pediatric risk of mortality III, PRISM III), lymphocyte subsets, C-reactive protein (CRP), tumor necrosis factor α (TNFα) were analyzed.ResultThe sCD 163 in sepsis/severe sepsis groups (171.04 ± 177.85) mg/L was significantly higher than that in control group (44.19 ± 86.48) mg/L (P < 0.01).sCD 163 in sepsis group [(105.32 ± 145.87) mg/L] was significantly lower than that of severe sepsis group [(233.32 ± 171.78) mg/L] (P < 0.05). sCD 163 level was significantly higher in lower PCIS score patients. (P < 0.01). The sCD 163 levels was higher in PRISM III ≥ 10 than the PRISM III < 10 group. The sCD 163 levels were higher in death group than the survival group. The sCD 163 was negatively correlated with CD4 +, CD4 +/CD8 + (R = -0.820, P < 0.05; R = -0.839, P < 0.01).ConclusionDetection of sCD 163 was helpful in predicting the severity of sepsis and severe sepsis, and sCD 163 may reflect the immune status of critically ill children with sepsis.
