A study published in *Kidney International* by Yichun Cheng et al. found that kidney disease is associated with in-hospital death in patients with COVID-19. The study, conducted at a tertiary teaching hospital in Wuhan, China, included 701 patients with COVID-19, of whom 113 (16.1%) died in hospital. The prevalence of acute kidney injury (AKI) was 5.1%, and patients with kidney disease had a significantly higher risk of in-hospital death. Elevated baseline serum creatinine, elevated blood urea nitrogen, AKI stages, proteinuria, and hematuria were independent risk factors for in-hospital death after adjusting for age, sex, disease severity, comorbidities, and leukocyte count. The findings highlight the importance of early identification and intervention for kidney involvement in COVID-19 to improve patient prognosis.The COVID-19 Resource Centre, established by Elsevier in January 2020, provides free information in English and Mandarin on the novel coronavirus.
