Abstract:
Objectives:To explore the value of heparin-binding protein (HBP) in the diagnosis and prognosis of patients with respiratory viral infections.Methods:The patients who were admitted to Emergency Department of Nanjing Hospital Affiliated to Nanjing Medical University from November 2018 to November 2020 were selected as the viral infection group, and the non-infected patients admitted in the same period as the non-viral infection group. Data of all patients’ general clinical information, peripheral white blood cell count (WBC), neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), and HBP in 24 h were collected. The differences in various indicators were compared between the two groups of patients, the receiver operating characteristic (ROC) curves were drawn, and the diagnostic value of each indicator for patients with respiratory virus infection were evaluated. The prognostic indicators such as sequential organ failure assessment (SOFA) score, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score within 24 h were recorded, and duration of ICU stay, antiviral treatment, ventilator and vasoactive agents to total length of hospital stay of patients in the viral infection group were calculated. The Spearman correlation analysis of HBP and the above indicators was performed to determine the prognostic value of HBP in patients with respiratory virus infections.Results:A total of 106 patients were included in the viral infection group, and 107 in the non-viral infection group. There were no significant differences in sex, age, and body mass index (BMI) between the two groups of patients (P>0.05). Compared with the non-viral infection group, the serum CRP and HBP of the viral infection group were significantly higher (P<0.05), while the WBC and NLR levels were significantly lower (P<0.05). There was no statistical difference in PCT between the two groups (P>0.05). HBP had the best diagnosis efficiency for respiratory viral infections, the areas under the ROC was 0.895, the optimal cut-off point was 13.625 μg/L, the sensitivity was 92.50% and the specificity was 76.60%. Correlation analysis showed that serum HBP levels within 24 h in the viral infection group were positively correlated with SOFA score and APACHEⅡ score in 24 h after admission (r = 0.756, P<0.05; r = 0.747, P<0.05). In the viral infection group, duration of ICU stay, antiviral treatment, and ventilator and vasoactive agents to total length of hospital stay were also positively correlated with serum HBP level (r = 0.873, 0.748, 0.830, and 0.794, P<0.05).Conclusions:HBP can be used as a favorable diagnostic indicator for patients with respiratory virus infections and has a good evaluation value for the prognosis.
