Abstract Objectives Ventilator-associated pneumonia (VAP) is difficult to diagnose using clinical criteria and no biomarkers have yet been proved to be sufficiently accurate. The use of the neutrophil-derived Heparin-binding protein (HBP) as a biomarker for pneumonia was investigated in this exploratory case–control study in two intensive care units at a tertiary referral hospital. Methods Patients with clinical signs of pneumonia were recruited and bronchoalveolar lavage fluid (BALF) or bronchial wash (BW) samples were collected. Mechanically ventilated and lung healthy subjects were recruited as controls. HBP was measured with enzyme-linked immunosorbent assay. Results BALF was collected from 14 patients with pneumonia and 14 healthy controls. Median HBP in BALF pneumonia samples was 14,690 ng/ml and controls 16.2 ng/ml (p < 0.0001). BW was collected from 10 pneumonia patients and 10 mechanically ventilated controls. Median HBP in BW pneumonia was 9002 ng/ml and controls 7.6 ng/ml (p < 0.0001). Conclusions These data indicate that HBP concentrations is significantly higher in lower airway samples from patients with pneumonia than control subjects and is a potentially useful biomarker for diagnosis of VAP.

Abstract Background: The pathophysiology of severe COVID-19 has been implicated to involve neutrophil activation in the blood and in the lungs and endothelial dysfunction. Heparin binding protein (HBP) is a neutrophil protein that plays an important role in bacterial sepsis and is a promising biomarker in severe infections. Syndecans and glypicans are potential markers of sheeding of the glycocalyx and endothelial dysfunction.The primary aims of this study were to assess whether HBP or syndecans and glypicans are involved in the pathophysiology of COVID-19 and if so, whether they can be used to predict severe disease preferably using a point-of-care test (POC) that can substitute more time-consuming analysis with enzyme-linked immunosorbent assay (ELISA).Methods: A prospective convenience sample study of biomarkers. The main cohort consisted of patients admitted to hospital with a confirmed COVID-19 diagnosis. Samples and clinical data were collected at admission, during admission and at discharge and samples were analyzed with ELISA kit (Axis-Shield Diagnostics) for measuring HBP concentration and a novel dry immunofluorescence analyzer (Jet-iStar 800) (Joinstar) for point-of-care testing.Results: Thirty-five COVID-19 patients were prospectively enrolled in the study. HBP was significantly elevated in COVID-19 patients with organ dysfunction (n= 23) compared to those without organ dysfunction (n=6), 24.7 ng/mL (95% CI 17.3-48.4) vs 10.6 ng/mL (95% CI 6.2-17.1 ng/mL), p=0.03. Syndecan-1 and Glypican-4 were not significantly elevated in patients with organ dysfunction. Syndecan-1, 62.1 ng/mL (44.4-102.0) vs 57.5 ng/mL (95% CI 46.0- 63.7), p=0.44 and glypican-4, 3292.4 pg/mL (95% CI 1707.5- 6790.6) vs 3962.7 pg/mL (95% CI 2653.6- 5823.5), p=0.80. The point-of-care (POC) HBP test showed good correlation to the standard ELISA with an R-value of 0.83. HBP measured by the POC device predicted development of COVID-induced organ dysfunction within 72 hours with an AUC of 0.88.Conclusions: The neutrophil-derived HBP is elevated prior to onset of organ dysfunction in patients with severe COVID-19 using a newly developed point-of-care test and hence HBP could be used in a clinical setting as a prognostic marker in COVID-19.

Background and aims Neutrophil-derived heparin binding protein (HBP; also known as azurocidin or CAP-37) is a key player in bacterial sepsis and a promising biomarker in severe infections. The aims of this study were to assess whether HBP is involved in the pathophysiology of COVID-19 and, if so, whether it can be used to predict severe disease preferably using a point-of-care test. Methods This was a prospective convenience sample study of biomarkers in patients admitted to Skåne University hospital in Sweden with a confirmed COVID-19 diagnosis. Plasma samples and clinical data were collected within 72h after admission, during hospital stay and at discharge. Plasma HBP concentrations samples were measured both with enzyme-linked immunosorbent assay (ELISA) and with a novel dry immunofluorescence analyzer (Joinstar) point-of-care test. Results Thirty-five COVID-19 patients were enrolled in the study. Twenty-nine patients had blood samples taken within 72h after admission. We compared the highest HBP value taken within 72h after admission in patients who eventually developed organ dysfunction (n = 23) compared to those who did not (n = 6), and found that HBP was significantly elevated in those who developed organ dysfunction (25.0 ng/mL (interquartile range (IQR) 16.6–48.5) vs 10.6 ng/mL (IQR 4.8–21.7 ng/mL), p = 0.03). Point-of-care test measurements correlated well with ELISA measurements (R = 0.83). HBP measured by the POC device predicted development of COVID-induced organ dysfunction with an AUC of 0.88 (95% confidence interval (CI) 0.70–1.0). Conclusions HBP is elevated prior to onset of organ dysfunction in patients with severe COVID-19 using a newly developed point-of-care test and hence HBP could be used in a clinical setting as a prognostic marker in COVID-19.

Abstract BACKGROUNDWe aimed to investigate the prognostic value of dynamic changes in heparin-binding protein (HBP) within the first 48 hours of hospital admission in sepsis patients.MethodsWe conducted a prospective observational study in the emergency intensive care unit of a tertiary care center. Patients who met SEPSIS-3 criteria were prospectively enrolled from August 2019 to January 2020. Serum levels of HBP were measured at admission, 24 hours, and 48 hours. Dynamic change in HBP was calculated as a percentage change between admission and 24 hours, and between admission and 48 hours. Accuracies of absolute level of HBP, dynamic change of HBP, and other biomarkers were compared with ROC analysis.ResultsA total of 245 patients were enrolled. After excluding patients not fulfilling the eligibility criteria and those died before 48 hours of admission, 185 patients were included for final analysis, of which 117 had sepsis, 68(36.76%) had septic shock, and 48(30%) died in the hospital. Day 1-HBP was correlated with procalcitonin (r2=0.21, p=0.004). Of all predictors of 30-day mortality, HBP clearance within 48 hours had the highest predictive accuracy (AUC: 0.82), followed by Day 1-HBP (AUC: 0.79), PCT (AUC: 0.75) and HBPc-24(AUC: 0.6). HBPc-48 > -17.14% had an independent impact on 30-day survival after adjusting for age, gender, shock status, and requirement of mechanical ventilation support.ConclusionsHBPc-48 can predict survival in critically ill patients with sepsis and can assist clinicians with risk stratification of these patients. Future multicenter studies are necessary to assess the generalizability of these findings.
