Abstract:
AIM:To investigate the role of lipopolysaccharide binding protein (LBP) for diagnosis and prog-nosis prediction in the septic patients.METHODS:A total number of 80 ICU patients were enrolled.The patients were divided into systemic inflammatory response syndrome ( SIRS) group and sepsis group, the patients in sepsis group were di-vided into non-survivor sub-group and survivor sub-group.We collected the serum samples and analyzed acute physiology and chronic health evaluation ( APACHE) II score on the first day of the patients hospitalized in ICU.In addition, we also selected 10 healthy volunteers and collected their serum samples.The serum concentrations of LBP, C-reactive protein ( CRP) and procalcitonin ( PCT) were measured by ELISA.ROC analysis of LBP, CRP, PCT and APACHE II score was conducted to discriminate among critically ill patients with sepsis and predict the prognosis of the patients with sepsis.RE-SULTS:The levels of the 4 indicators in the septic patients were higher than those in the patients of SIRS (P<0.05).In addition, serum LBP and APACHE II score in the non-survivor sub-group were higher than those in the survivor sub-group (P<0.05), whereas no difference of the PCT and CRP levels between survivors and non-survivors with sepsis was ob-served.LBP levels greater than 26.84 mg/L had 97.1% sensitivity and 95.9% specificity to discriminate between SIRS and sepsis.LBP levels greater than 54.16 mg/L had 85.2%sensitivity and 80.0%specificity for prognosis of unfavorable outcome.CONCLUSION:LBP level was more accurately correlated with diagnosis or prognosis prediction than CRP or PCT in patients with sepsis.
