Comparison of COVID-19 Patients With and Without Acute Kidney Injury at ICU Admission: Evaluation of Associated Factors and Outcomes

Le résumé fourni par la source

Although acute kidney injury (AKI) is common among patients with coronavirus disease 2019 (COVID-19), there are only limited data on its occurrence at intensive care unit (ICU) admission. Assessing the factors associated with AKI is essential for early diagnosis and intervention. This study aims to compare the clinical and laboratory characteristics and survival outcomes of COVİD-19 patients with and without AKI at ICU admission and determine the factors associated with AKI. In this study, patients with SARS-CoV-2 infection were categorized based on the presence (AKI group) or absence (non-AKI group) of AKI. Clinical and laboratory data and outcomes were analyzed retrospectively. Of the 712 patients included in this study, 198 were assigned to the AKI group and 514 were assigned to the non-AKI group. Patients with AKI had more comorbidities and higher disease severity; higher rates of invasive mechanical ventilation, vasopressor therapy, and mortality; and longer hospital stays (p < 0.05). Our multivariate analysis identified advanced age, a high Acute Physiology and Chronic Health Evaluation II score, a high neutrophil-to-lymphocyte ratio, a low albumin level, and the presence of comorbidities as independent factors associated with AKI. In patients with COVID-19, AKI observed at ICU admission is associated with advanced age and increased disease severity. The early diagnosis and monitoring of patients may improve clinical outcomes.
