Abstract
Background and Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) was described in December 2019 for the first time, and it was responsible for a global pandemic. An alarming number of patients with coronavirus disease 2019 (COVID-19) also developed acute kidney injury (AKI), especially those who required extracorporeal membrane oxygenation (ECMO) therapy for acute respiratory distress syndrome (ARDS). The aim of our retrospective observational study was to assess the prognostic significance of AKI in these patients. This study observed, in COVID-19 patients admitted to an intensive care unit (ICU), AKI stages and the need for renal replacement therapy (RRT), assessing the risk factors and outcomes. Moreover, we evaluated the mortality rate of patients treated by ECMO. Materials and Methods: Between November 2020 and December 2022, among 396 patients admitted to our intensive care unit (ICU) diagnosed with SARS-CoV-2 infection, we selected patients with severe ARDS requiring veno-venous (vv) ECMO support and AKI. Results: The 30-day mortality after ECMO positioning was 85.7%. A Cox regression revealed a significant advantage for RRT with a high cut-off (HCO) hemofilter both for ICU mortality (HR 0.17 [95% CI: 0.031–0.935], p = 0.035) and 15 day-mortality after the start of vv-ECMO (HR 0.13 [95%CI: 0.024–0.741], p= 0.021), whereas the early onset of vasoplegic shock after ECMO implantation indicated a higher risk of death (HR 11.55 [95% CI: 1.117–119.567], p = 0.04) during the ICU stay. Conclusions:COVID-19 induces a high risk of AKI and RRT. In our cohort, hypertension, pre-existing renal disease, and mechanical ventilation represented independent risk factors for AKI. Patients requiring ECMO support had a high mortality rate. The early implementation of RRT reduced the risk of death during the ICU stay.
