Text of the abstract

Data suggests that invasive fungal infections (IFI) might complicate COVID-19.

Our goal was to describe characteristics of IFI among critically ill COVID-19 adults.

A retrospective observational case-series analysis was done between March–July 2020. Consecutive patients with critical COVID-19 were eligible, and have been included when proven or putative/probable IFI could be confirmed during their course. For COVID-19 diagnosis, ECDC definitions and WHO severity criteria were followed. Candidaemia was defined according to the ESCMID 2012 guideline. Invasive pulmonary aspergillosis (IPA) was diagnosed following EORTC/MSG and modified AspICU criteria. Outcome variables were rates of IFIs, in-hospital all-cause mortality, rate and time to negative respiratory SARS-CoV-2 PCR.

From 90 eligible patients, 20 (22.2%) fulfilled criteria for IFI. Incidence rate for IFI was 2.02 per 100 patient-days at ICU. Patients were mostly elderly males with significant comorbidities, requiring mechanical ventilation because of ARDS. IFI could be classified as candidaemia in 7/20 (40%), proven IPA in 3/20 (15.0%), putative IPA in 13/20 (65.0%). Isolated species of candidaemia episodes were Candida albicans (4/9, 44.4%), Candida glabrata (3/9, 33.3%), Candida parapsilosis (1/9, 11.1%), Candida metapsilosis (1/9, 11.1%). Mold isolates were Aspergillus fumigatus, BAL galactomannan positivity was prevalent (16/20, 80.0%). Mortality was 12/20 (60.0%) with a median time to death of 31.0±37.0 (5–89) days. Only 9/20 (45.0%) patients reached SARS-CoV-2 PCR negativity after a median time of 20.0±12.0 (3–38) days.

In this small cohort of critically ill COVID-19 adults, morbidity and mortality related to invasive fungal infections proved to be significant.
