Acute kidney injury outcomes of COVID-19 confirmed patients in a Philippine tertiary hospital: A retrospective study

The novel coronavirus (COVID-19) is known to be the fifth pandemic causing massive deaths worldwide. This virus has not only been deeply associated with acute respiratory distress, but also acute kidney injury (AKI). This study describes the baseline characteristics and various outcomes of AKI based on the KDIGO 2012 Clinical Practice Guidelines in patients hospitalized with COVID-19 at a Philippine tertiary hospital. A total of 195 patient records were retrospectively reviewed for the study. Of the 195 patients, 81(42%) patients developed AKI. Significant baseline characteristics included older age (56.28 + 14.12), presence of hypertension (p=0.004), diabetes mellitus (p=0.002), and cardiovascular disease (p=0.003). Also, the use of diuretics, inotropes and antibiotics were more prevalent in patients who developed AKI. Most of the patients who had AKI were categorized as stage 1 (49.38%). Mechanical ventilation was significantly (p<0.001) more prevalent in patients with AKI (20.99%) compared to patients without AKI (5.26%). There was significantly higher rates (p<0.001) of renal replacement therapy in patients with AKI (30.86%). Lastly, higher mortality rates were observed in patients with AKI (50.62%) versus patients without AKI (12.28%). Our study demonstrated that patients with COVID-19 can develop AKI and tend to have a poorer prognosis.
