Many individuals who develop COVID-19 experience kidney damage, or acute kidney injury (AKI). Investigators recently evaluated the incidence, risk factors, and prognosis of AKI in adults with COVID-19. Their findings appear in an upcoming issue of CJASN.

The study was conducted in Tongji hospital in Wuhan, China, which was assigned responsibility for the treatment of severe COVID-19 cases by the local government. Investigators led by Gang Xu, PhD and Shuwang Ge, MD analyzed information pertaining to 1,392 patients who tested positive for the virus that causes COVID-19.

The team found that, in patients with COVID-19, AKI is uncommon but is linked with a high risk of in-hospital mortality. Seven percent of patients developed AKI during hospitalization, many within seven days after admission. The in-hospital mortality rate was 10% in patients without AKI vs 72% in patients with AKI. After adjusting for potential confounding factors, AKI was associated with a five-times higher odds of dying while in the hospital. Also, the risk of death was higher with greater severity of AKI.
