Background: Since the emergence of the pandemic of SARS-CoV-2, a high reported incidence of VAP in COVID-19 sustained by carbapenem resistant Acinetobacter baumannii (CRAB) has been observed, but data are scarce to date. Materials and methods: We retrospectively collected COVID-19 patients who developed CRAB-VAP - defined according to Center for Diseases Control (CDC) 2020 criteria and European Society of Clinical Microbiology and Infectious Diseases (ESCMID) or Infectious Diseases Society of America (IDSA) guidelines - to describe characteristics and outcome. Results: Among 21 patients with CRAB-VAP in COVID-19, median age was 66 years (IQR 41-80). Median time of VAP-onset was 7 days (IQR 0-28 days) from ICU - admission and 76.2% had septic shock. Treatment regimens were all colistin-based, in 28% (n=6) including ampicillin/sulbactam and rifampicin. In three cases, cefiderocol was started as rescue. Survival rate at 28-days was 35% (n=7). Conclusion: Non-fermenting Gram-negative bacteria are an emerging aetiology of VAP in COVID-19 patients. This underscores the urgent need for proper microbiological identification to address therapies and infection control protocols.

Abstract

Background: Since the emergence of the pandemic of SARS-CoV-2, a high reported incidence of VAP in COVID-19 sustained by carbapenem resistant Acinetobacter baumannii (CRAB) has been observed, but data are scarce to date. Materials and methods: We retrospectively collected COVID-19 patients who developed CRAB-VAP - defined according to Center for Diseases Control (CDC) 2020 criteria and European Society of Clinical Microbiology and Infectious Diseases (ESCMID) or Infectious Diseases Society of America (IDSA) guidelines - to describe characteristics and outcome. Results: Among 21 patients with CRAB-VAP in COVID-19, median age was 66 years (IQR 41-80). Median time of VAP-onset was 7 days (IQR 0-28 days) from ICU - admission and 76.2% had septic shock. Treatment regimens were all colistin-based, in 28% (n=6) including ampicillin/sulbactam and rifampicin. In three cases, cefiderocol was started as rescue. Survival rate at 28-days was 35% (n=7). Conclusion: Non-fermenting Gram-negative bacteria are an emerging aetiology of VAP in COVID-19 patients. This underscores the urgent need for proper microbiological identification to address therapies and infection control protocols.
