Abstract:

Objective

To investigate the value of heparin binding protein (HBP) level in early diagnosis of disease severity and prognosis prediction in elderly sepsis patients.

Methods

A multi-center prospective study was used. Patients admitted to the intensive care unit (ICU) of 18 tertiary A hospitals across the country during July 2014 and March 2015 were enrolled in the study. Once patients were included in the study, they received fluid resuscitation and active treatment immediately according to the guidelines as needed. Venous blood was collected on the day of enrollment and 24 hours after enrollment, and the levels of plasma HBP, procalcitonin (PCT), and C-reactive protein (CRP) were detected. According to the sepsis 2.0 diagnostic criteria, the patients were divided into sepsis group, severe sepsis group, septic shock group and non-infectious systemic inflammatory response syndrome (SIRS) group. The gender, age, underlying diseases, acute physiology and chronic health scoreⅡ (APACHEⅡ) score, 28-day mortality, and the levels of HBP, PCT, CRP were compared among the groups. The correlation between HBP, PCT, CRP levels and APACHEⅡ score were analyzed using Spearman non parametric correlation coefficient, and the predictive value of HBP for the prognosis of patients was evaluated using survival function.

Results

A total of 295 patients were included in the study, including 124 patients with sepsis, 58 patients with severe sepsis, 73 patients with septic shock, and 40 patients with SIRS. There were differences in APACHEⅡ scores, baseline HBP, PCT and CRP levels among the groups (F=3.841; H=14.470, 44.298, 14.778; P < 0.01), and only HBP was correlated with APACHEⅡscore on the day after enrollment (r=-0.196, P < 0.05). The 28-day mortality rates in the SIRS group, sepsis group, severe sepsis group, and septic shock group were 2.50%, 2.42%, 18.97%, and 20.55%, respectively, and the survival rate of patients with HBP≥15 μg/L was higher (χ2=0.020, P < 0.05).

Conclusion

The level of HBP is correlated with the severity of disease in elderly sepsis patients. Baseline HBP can be used to predict the prognosis, and patients with baseline HBP >15 ng/mL have an increased risk of death.
