Patients with more severe cases of coronavirus disease-19 (COVID-19) may be at greater risk for developing acute kidney injury (AKI). The aim of our study was to analyze incidence and outcomes of AKI in critically ill patients with COVID-19. Our study prospectively followed about 198 patients with COVID-19 admitted to intensive care unit (ICU), Al Adan Hospital, Kuwait, for developing AKI and outcomes. Age, gender, nationality, history of hypertension, diabetes mellitus, ischemic heart disease, congestive heart failure, bronchial asthma, and chronic obstructive pulmonary disease were analyzed. The need for mechanical ventilation (MV), extracorporeal membrane oxygenation, inotropes, and medications was recorded. Causes of AKI, indication of dialysis, dialysis modality, dialysis outcomes, and mortality were analyzed. Our study reported that61 out of 198 (30.8%) ICU patients positive for COVID-19, developed AKI according to the Kidney Disease Improving Global Outcomes definition of AKI. Forty-eight out of 61 (79%) patients need continuous renal replacement therapy using continuous venovenous hemodiafiltration. Thirty-seven (61%) out of 61 patients were with severe sepsis syndrome. The most common cause of AKI was sepsis, cytokine storm, hypovolemia, heart failure, MV, and nephrotoxic drugs. Twenty-four patients (39%) out of 61 patients died, and the most common cause of death was sepsis, cytokine storm with respiratory failure, heart failure, and AKI. The outcome of AKI was as follows: six patients (10%) had complete recovery, five patients had partial recovery (8%), and 26 (43%) patients became dialysis dependent. Incidence of AKI is high in ICU COVID-19 patients and is associated with poor outcomes and high mortality. Early detection and specific therapy of kidney changes, including adequate hemodynamic support and avoidance of nephrotoxic drugs, may help to improve critically ill patients with COVID-19.
