AKI is a common complication associated with COVID-19. Thiago Terzian Ganadjian, MD, and colleagues at Universidade Federal Sao Paulo, Sao Paulo, Brazil, conducted a study to examine the frequency and association of clinical variables in patients who developed CKD and ESRD following AKI related to COVID-19. The researchers reported results of the 1-year follow-up study during a poster session at the American Society of Nephrology Kidney Week 2022. The poster was titled The Emergence of CKD After COVID-19 Related AKI. The study included 182 survivor patients who were admitted to the center’s ward and intensive care unit with COVID-19 between April 2020 and March 2021. Inclusion criteria were age ≥18 years and COVID-19 confirmed on reverse transcription-polymerase chain reaction test. Exclusion criteria included ESRD prior to hospitalization. Kidney Disease: Improving Global Outcomes criteria were used to define AKI and CKD. The researchers assessed the frequency of AKI and then compared selected clinical variables in two subgroups: CKD after COVID-19-related AKI and non-CKD after COVID-19. Univariate and multivariate analyses were conducted. A total of 137 patients
