ABSTRACT
We conducted a retrospective cohort study to report the clinical characteristics, incidence and outcomes of patients with severe COVID-19 with acute kidney injury (AKI). One-hundred and sixtytwo intensive care unit (ICU) admitted patients in a tertiary level hospital in the city of Buenos Aires with COVID-19 diagnosis were included. We hypothesized that COVID-19 related AKI would develop in the period of more severe hypoxemia as an early event and late AKI would be more probably related to intensive care unit complications. For this purpose, we divided subjects into two groups those with early AKI and late AKI, before and after day 14 from symptom onset, respectively. A stepwise multivariate analysis was conducted to find possible AKI predictors. AKI incidence was 43.2% (n = 70) of the total patients admitted into ICU with severe COVID-19, 11.1% (n = 18) required renal replacement therapy. In-hospital mortality was higher (58.6%) for the AKI group. AKI occurred on a median time of 10 (IQR 5.5-17.5) days from symptom onset. A history of hypertension or heart failure, age and invasive mechanical ventilation (IMV) requirement were identified as risk factors. Late AKI (n = 25, 35.7%) was associated with sepsis and nephrotoxic exposure, whereas early AKI occurred closer to the timing of IMV initiation and was more likely to have an unknown origin. In conclusion, AKI is frequent among critically ill patients with severe COVID-19 and it is associated with higher in-hospital mortality.
