Abstract

Italy has experienced one of the harshest and earliest COVID-19 epidemics, with the number of patients infected that followed, from the end of February up to the end of March, an exponential trend [1]. Between the 6 March and the 2 May, 394 patients were confirmed positive for SARS-CoV-2 at the University Hospital of Rome Policlinico Umberto I (PUI) [2]. At the PUI, 5 COVID-19 devoted wards were organized, including two brand new ICUs, counting 32 dedicated to COVID-19 patients: the first was the old general ICU converted into a dedicated COVID-19 ICU, while the second was created in the spaces of four operating rooms (new ICU). In the period of this study, a total of 80 COVID-19-affected patients were hospitalized in the two ICUs at PUI. Among them, 65 patients were screened for carbapenemase producing Enterobacterales (CPE) colonization (Brilliance™ CRE medium plates, Oxoid LTD, Basingstoke, UK): 41 out of 47 SARS-CoV-2 patients hospitalised in the old ICU and 24 out of 33 in the new one. Carbapenemase-producing K. pneumoniae were detected in 14/41 patients (34%) only in the old ICU. No CPE were detected from rectal swabs tested in patients hospitalized in the new ICU. In the same period, 11 CPEs were identified from the 39 rectal swabs out of 48 SARS-CoV-2-negative patients (28%) hospitalized in the non-COVID-ICU of the same hospital. Seven COVID-19 patients developed CPE co-infection (5 bronchoalveolar lavages and 2 blood cultures tested positives for carbapenemase-producing K. pneumoniae), while in the non-COVID-19 ICU 7 bloodstream infections (BSIs) also occurred (Table 1). Symptomatic patients were successfully treated with ceftazidime-avibactam.
