Efficacy and safety of a 72-h infusion of prostacyclin (1 ng/kg/min) in mechanically ventilated patients with pulmonary infection and endotheliopathy-protocol for the multicenter randomized, placebo-controlled, blinded, investigator-initiated COMBAT-ARF trial.

ABSTRACT:

Background

Acute respiratory failure (ARF) is common in critically ill patients, and 50% of patients in intensive care units require mechanical ventilation [3, 4]. The COVID-19 pandemic revealed that COVID-19 infection induced ARF caused by damage to the microvascular pulmonary endothelium. In a randomized clinical trial, mechanically ventilated COVID-19 patients with severe endotheliopathy, as defined by soluble thrombomodulin (sTM) ≥ 4 ng/mL, were randomized to evaluate the effect of a 72-h infusion of low-dose prostacyclin 1 ng/kg/min or placebo. Twenty-eight-day mortality was 21.9% versus 43.6% in the prostacyclin and the placebo groups, respectively (RR 0.50; CI 0.24 to 0.96 p = .06). The aim of the current trial is to investigate if this beneficial effect and safety of prosta
