Heparin-binding protein and lung edema in ICU patients

Heparin-binding Protein (HBP) and Lungedema in ICU Patients. Is There a Correlation Between HBP and Pulmonary Vascular Permeability? A Prospective Observational Study

Observational Umeå University · NCT07434908

This will test whether blood levels of heparin-binding protein relate to lung fluid and total fluid balance in adult ICU patients monitored with a PiCCO device.

What this trial studies

This single-center observational cohort will enroll about 25 adult ICU patients who are monitored with a PiCCO hemodynamic surveillance device. Researchers will collect blood samples to measure heparin-binding protein (HBP) and record PiCCO-derived measures such as extravascular lung water (EVLW), pulmonary blood volume (PBV), and the pulmonary vascular permeability index (PVPI). They will also track patients' cumulative fluid balance and relevant clinical data. The study will analyze correlations between plasma HBP concentrations and measures of lung vascular permeability, lung water, and total fluid balance.

Who should consider this trial

Good fit: Adults (over 18) in the ICU who are being monitored with a PiCCO system and are not transferred from another ICU are ideal candidates.

Not a fit: Patients under 18, those not monitored with PiCCO, or patients transferred from another ICU would not be eligible and are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the findings could help clinicians use HBP levels to identify increased lung vascular permeability and guide fluid management in critically ill patients.

How similar studies have performed: Previous work has linked HBP to vascular leak in inflammatory states and PiCCO-derived PVPI is an established measure of lung permeability, but direct correlation of HBP with PiCCO measures is relatively novel.
