Acute kidney injury (AKI) has garnered attention as it is frequently observed in COVID-19 and is associated with severe disease. Furthermore, in recent years, reduced renal function has been identified as a long-term sequela following COVID-19. However, some reports indicate that AKI caused by COVID-19 results in milder long-term renal impairment compared to other causes of AKI, suggesting it may merely represent the progression from AKI to chronic kidney disease (CKD). The objective of this study is to evaluate the incidence of AKI and the subsequent decline in renal function following infection with COVID-19, bacterial pneumonia, and influenza, and to investigate the differences between these conditions.
We conducted a retrospective study of COVID-19 patients hospitalized at our institution from March 2020 to September 2022, bacterial pneumonia patients hospitalized during the same period, and influenza infection patients hospitalized from January 2016 to December 2019. Renal function was followed for 2 years after discharge. We compared the incidence of AKI, rate of renal function decline, and prognostic factors among the three disease groups.
During the study period, 929 cases of COVID-19 (mean age 67.1 years), 761 cases of bacterial pneumonia (mean age 84.6 years), and 265 cases of influenza infection (mean age 83.4 years) were hospitalized. Follow-up of renal function after discharge was possible for 276, 369, and 185 cases, respectively. The incidence rates of AKI at admission were 12.2%, 38.5%, and 14.3%, respectively. The changes in eGFR over two years were -2.2 mL/min/1.73m²/year, +4.7 mL/min/1.73m²/year, and -1.8 mL/min/1.73m²/year, respectively.
It has been revealed that AKI occurs during hospitalization not only for COVID-19 but also for bacterial pneumonia and influenza infections. Factors such as age and underlying conditions are thought to influence the incidence rate of AKI and subsequent changes in renal function. This report incorporates statistical analysis and a review of the literature.
