Significance of high mobility group box 1 (HMGB1) in children with sepsis / 中国小儿急救医学

ABSTRACT

Objective To investigate the change of serum HMGB1 level and its clinical significance in children with sepsis.Methods Serum HMGB1 and procalcitonin (PCT) levels were determined in 30 healthy individuals and 46 children with sepsis,and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scoring system was evaluated in children with sepsis.These indexes were also collected on the third and fifth days.The correlations between serum HMGB1 level and serum PCT level as well as APACHE Ⅱ score were analyzed.Results Serum HMGB1 levels in children with sepsis on the first day,the third day and the fifth day were significantly higher than those in control group,these differences were statistically significant [(26.28 ± 1.54) ng/ml,(20.32 ± 1.29) ng/ml,(12.84 ± 1.06) ng/ml vs (1.52 ± 0.29) ng/ml,P ＜0.05],HMGB1 levels among three time points were also significantly different(P ＜0.05).The serum HMGB 1 levels were positively correlated with the PCT levels (r =0.931,P ＜ 0.05) and APACHE Ⅱ score (r =0.915,P ＜ 0.05).Conclusion Serum HMGB1 level is obviously elevated in children with sepsis,and the level of HMGB1 can reflect the severity of sepsis.
