Clinical value of serum new molecular markers in the early diagnosis of sepsis in elderly patients with burns / 中华老年医学杂志

ABSTRACT

Objective@#To investigate the clinical value of the serum new molecular markers, soluble triggering receptor expressed on myeloid cells-1(sTREM-1)and soluble hemoglobin scavenger receptor(sCD163), in the diagnosis of sepsis in elderly patients with burns.@*Methods@#A total of 58 inpatients with burns from Jun 2017 to June 2018 were enrolled in the study.Patients were divided into three groups the sepsis group(n=12), the localized infection group(n=21)and the non-infection group(n=29). The levels of sTREM-1 and sCD163 were determined by enzyme-linked immunosorbent assays(ELISAs). The clinical diagnostic value of sTREM-1 and sCD163 was assessed by receiver operating characteristic(ROC)curve analysis.@*Results@#There was a statistically significant difference in the levels of sTREM-1 and sCD163 at day 1 between the three groups(F=20.994 and 38.363, P<0.01). Serum levels of sTREM-1 and sCD163 were higher in the sepsis group than in the localized infection group and the non-infection group.Serum levels of sTREM-1 and sCD163 were higher in the localized infection group than in the non-infection group.Serum levels of sTREM-1 and sCD163 were lower at day 7 than those at day 1 in all groups(F=21.242 and 41.035, P<0.01). Serum sTREM-1 levels were positively correlated with serum sCD163 levels(r=0.609, P=0.000). The AUC of sTREM-1 and sCD163 for the diagnosis of sepsis was 0.880(95%CI 0.816~0.926).@*Conclusions@#Serum levels of sTREM-1 and sCD163 are elevated with increasing degrees of infection.Monitoring serum sTREM-1 and sCD163 levels is helpful for the diagnosis of sepsis in elderly patients with burns.
