Objective: The aim of the study was to evaluate the association between chronic kidney disease (CKD) and new onset renal replacement therapy (RRT) with the outcome of Coronavirus Disease 2019 (COVID-19) in patients. Methodology: A systematic literature search from several databases was performed on studies that assessed CKD, use of RRT, and the outcome of COVID-19. The composite of poor outcome consisted of mortality, severe COVID-19, acute respiratory distress syndrome (ARDS), need for intensive care, and use of mechanical ventilator. Results: Nineteen studies with a total of 7216 patients were included. CKD was associated with increased composite poor outcome (RR 2.63 [1.33, 5.17], P =.03; I2 = 51%, P =.01) and its subgroup, consisting of mortality (RR 3.47 [1.36, 8.86], P =.009; I2 = 14%, P =.32) and severe COVID-19 (RR 2.89 [0.98, 8.46], P =.05; I2 = 57%, P =.04). RRT was associated with increased composite poor outcome (RR 18.04 [4.44, 73.25], P <.001; I2 = 87%, P <.001), including mortality (RR 26.02 [5.01, 135.13], P <.001; I2 = 60%, P =.06), severe COVID-19 (RR 12.95 [1.93, 86.82], P =.008; I2 = 81%, P <.001), intensive care (IC) (RR 14.22 [1.76, 114.62], P <.01; I2 = 0%, P <.98), and use of mechanical ventilator (RR 34.39 [4.63, 255.51], P <.0005). Conclusion: CKD and new-onset RRT were associated with poor outcome in patients with COVID-19.
