ABSTRACT

Introduction:

We aimed to describe the incidence, risk factors, and clinical outcomes of bacterial and fungal co-infections and superinfections in intensive care patients with COVID-19 in a retrospective observational study. Method(s) A retrospective cohort of intensive care patients with confirmed SARS-CoV-2 by PCR was analysed from January to March 2021. This was contrasted to a control group of influenza-positive patients admitted during 2012-2022. Patient demographics, microbiology and clinical outcomes were analysed. Result(s) A total of 70 patients with confirmed SARS-CoV-2 were included;6 (8.6%) of 70 had early bacterial isolates identified rising to 42 (60%) of 70 throughout admission. Blood cultures, respiratory samples, and urinary samples were obtained from 66 (94.3%), 18 (25.7%) and 61 (87.1%) COVID-19 patients. Positive blood culture was identified in 13 patients (18.6%). Bacteraemia resulting from respiratory infection was confirmed in 3 cases (all ventilator-associated). Line-related bacteraemia was identified in 9 patients (6 Acinetobacter baumannii, 4 Enterococcus spp. and 1 Pseudomonas aeruginosa and 1 Micrococcus lylae). No concomitant pneumococcal, Legionella or influenza co-infection was detected. Invasive fungal infections with Aspergillus spp. were identified in 2 cases. Pneumococcal coinfections (7/68;10.3%) were identified in the control group of confirmed influenza infection;clinically relevant bacteraemias (6/68;8.8%), positive respiratory cultures (15/68;22.1%). The rate of hospital- acquired infections was 51.4% for COVID-19 and 27.9% for influenza. Longer intensive care stay, type 2 diabetes, obesity and hematologic diseases were independent risk factors for superinfections in the COVID-19 cohort. Conclusion(s) Respiratory coinfections occurred in influenza but not in COVID-19 patients. The rate of hospital-acquired infections (51.4% for COVID-19;27.9% for influenza) was unexpectedly high in both groups.
