An Unobvious Cause of Kidney Diseases Identified 0 7

A previous coronavirus infection can significantly increase the risk of kidney damage. This conclusion was reached by researchers from Penn State College of Medicine after analyzing data from more than three million people. The results were published in the journal Communications Medicine (CM).

Compared to influenza, individuals with a history of COVID-19 had a 2.3 times higher risk of acute kidney injury, a 1.4 times higher risk of chronic kidney disease, and a nearly 4.7 times higher likelihood of developing kidney failure. Participants with pre-existing kidney diseases were not included in the analysis, allowing for the assessment of new cases following the infection.

The observation lasted on average about a year after the illness. While influenza had a short-term and relatively mild impact on the kidneys, COVID-19 demonstrated a more persistent effect, increasing the risk of both acute and long-term organ damage. The scientists attribute this to the fact that kidney cells contain receptors through which the SARS-CoV-2 virus penetrates the tissues.

The authors emphasize that a previous coronavirus infection should be considered a risk factor when assessing patients' conditions, especially in individuals with diabetes and hypertension. More frequent monitoring of kidney function may help identify abnormalities at early stages and reduce the risk of severe complications.
