Long-term consequences of COVID-19 for kidneys: a manageable complication or a time bomb?

The impact of COVID-19 on chronic kidney disease (CKD) has already been confirmed by researchers around the world. However, there is still insufficient data in the literature how the new coronavirus infection can affect kidney function without signs of CKD before. The aim of this study was to determine the relative risk of developing stages 4-5 CKD in patients who had COVID-19 and did not have signs of kidney damage before, depending on the severity of the coronavirus infection, the fact of hospitalization and the complication of acute kidney injury. The results of the study demonstrate that the development of late (4-5) stages of CKD can be directly associated with COVID-19, especially in patients with severe COVID-19, hospitalization or acute kidney injury, which is consistent with many studies in this area, in particular in patients without signs of CKD before.
