Abstract:

Objective

To evaluate the value of plasma heparin binding protein (HBP) in the early diagnosis of sepsis, and to explore the application value of HBP for the severity and prognosis assessment of sepsis.

Methods

A prospective observational study was conducted in Department of Critical Care Medicine of Northern Jiangsu People's Hospital. One hundred and ninety-eight patients with confirmed infections from June 2019 to June 2021 were enrolled in this study. According to the illness severity of sepsis, patients were assigned as non-sepsis (n=48), sepsis (n=52) and septic shock (n=98). Forty patients in the same period without infection were selected as control group. The differences in HBP, procalcitonin (PCT), C-reactive protein (CRP), white blood cell count (WBC) and lactate (Lac) levels were compared and analyzed. The prognostic values on sepsis diagnosis and 28-day mortality were evaluated through drawing receiver operating characteristic (ROC) curve. Logistic regression analysis was used to clarify the factors affecting the prognosis of sepsis.

Results

The plasma level of HBP was obviously elevated in septic shock group than patients in other three groups (P<0.05), while patients in sepsis group had higher HBP than patients in non-sepsis group (P<0.05). Take an optimal cutoff value of 35.8 ng/ml, the area under the curve (AUC) for HBP to distinguish sepsis from from non-sepsis was 0.922. The levels of HBP and Lac were also significantly elevated in non-survivors compared to survival group (P<0.05). Ho sever, no significant differences of PCT, CRP and WBC levels were found between the two groups. Plasma HBP>97.6 ng/ml was associated with elevated mortality, AUC of HBP predicting 28-day mortality of sepsis patients was 0.750, with a sensitivity of 65.5% and a specificity of 77.7%. The plasma HBP levels in death group were higher than those in survival group at 0 h, 24 h, 48 h and 72 h after admission (P<0.05). Meanwhile, in death group, the plasma HBP level showed no statistical differences in each time point compared with that in the previous time point (P>0.05).

Conclusion

HBP can be a better and more specific early predictor of sepsis compared with PCT, CRP, WBC and Lactate. Meanwhile, the level and tendency of HBP has valuable to evaluate the severity of sepsis and mortality.
