Background
Coronavirus disease 2019 (COVID-19) pandemic disrupted adherences to healthcare-associated infection (HAI) prevention protocols. Herein, we studied the characteristics of all HAIs occurring in critically ill COVID-19 patients.
Methods
A retrospective, single-center cohort of critical COVID-19 patients during 2021. Microbiological samples were collected if HAI was suspected. We analyzed all factors that could potentially induce HAI, using septic shock and mortality as endpoints.
Results
Sixty-four among 161 included patients (39.7%) presented a total of 117 HAIs with an incidence density of 69.2 per 1,000 hospitalization days. Compared to the prior COVID-19 period (2013–2019), the identification of HAI increased in 2021. HAIs were classified into ventilator-associated pneumonia (VAP; n=38), bloodstream infection (n=32), urinary tract infection (n=24), catheter-related infection (n=12), and fungal infection (n=11). All HAIs occurred significantly earlier in the post–COVID-19 period (VAP: 6 vs. 10 days, P=0.045, in 2017 and 2021). Acinetobacter baumannii (39.5%) and Klebsiella pneumoniae (27%) were the most commonly isolated pathogens that exhibited a multidrug-resistant (MDR) profile, observed in 89% and 64.5%, respectively. The HAI factors were laboratory abnormalities (odds ratio [OR], 6.4; 95% confidence interval [CI], 2.3–26.0), cumulative steroid dose (OR, 1.9; 95% CI, 1.3–4.0), and invasive procedures (OR, 20.7; 95% CI, 5.3–64.0). HAI was an independent factor of mortality (OR, 8.5; P=0.004).
Conclusions
During the COVID-19 era, the incidence of HAIs increased and MDR isolates remained frequent. A severe biological inflammatory syndrome, invasive devices, and elevated cumulative steroid dosages were related to HAIs. HAI was a significant death factor.

AbstractAbstract PDF
Background
The kidney represents a potential target for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Acute kidney injury (AKI) can occur through several mechanisms and includes intrinsic tissue injury by direct viral invasion. Clinical data about the clinical course of AKI are lacking. We aimed to investigate the proportion, risk factors, and prognosis of AKI in critical patients affected with coronavirus disease 2019 (COVID-19).
Methods
A case/control study conducted in two intensive care units of a tertiary teaching hospital from September to December 2020.
Results
Among 109 patients, 75 were male (69%), and the median age was 64 years (interquartile range [IQR], 57–71 years); 48 (44%) developed AKI within 4 days (IQR, 1–9). Of these 48 patients, 11 (23%), 9 (19%), and 28 (58%) were classified as stage 1, 2, and 3, respectively. Eight patients received renal replacement therapy. AKI patients were older and had more frequent sepsis, acute respiratory distress syndrome, and rhabdomyolysis; higher initial urea and creatinine; more marked inflammatory syndrome and hematological disorders; and required more frequent mechanical ventilation and vasopressors. An elevated level of D-dimers (odds ratio [OR], 12.83; 95% confidence interval [CI], 1.9–85) was an independent factor of AKI. Sepsis was near to significance (OR, 5.22; 95% CI, 0.94–28; P=0.058). Renal recovery was identified in three patients. AKI, hypoxemia with the ratio of the arterial partial pressure of oxygen and the inspiratory concentration of oxygen <70, and vasopressors were identified as mortality factors.
Conclusions
AKI occurred in almost half the patients with critical COVID-19. A high level of D-dimers and sepsis contributed significantly to its development. AKI significantly worsened the prognosis in these patients.
