In this retrospective case-control study, we have observed a higher prevalence of ventilator-associated pneumonia (VAP) and MDR VAP in C-ARDS as compared with NC-ARDS patients. Further, probably multicenter, research work are needed to confirm this association.

We assessed 90 C-ARDS and 82 NC-ARDS patients, who were mechanically ventilated for more than 48 hours.

At ICU admission, there were significantly fewer bacterial coinfections documented in C-ARDS than in NC-ARDS: 14 (16%) vs 38 (48%), p<0.01. Conversely, significantly more patients developed at least one VAP episode in C-ARDS as compared with NC-ARDS : 58 (64%) vs. 36 (44%), p=0.007. The probability of VAP was significantly higher in C-ARDS after adjusting on death and ventilator weaning. We conducted a monocenter retrospective study comparing the prevalence of VAP and invasive aspergillosis between patients with COVID-19 related acute respiratory distress syndrome (C-ARDS) and those with non-SARS-CoV-2 viral ARDS (NC-ARDS).
