COVID-19 outbreak and the impact on renal disorders: A rapid review

In this rapid review, we aimed to evaluate the effect of coronavirus disease 2019 (COVID-19) on renal functions and mortality of patients with kidney diseases. We searched MEDLINE, The Cochrane Library, Scopus, Embase, Web of Science, UpToDate, and TRIP databases using the following keywords: COVID-19, COVID19, 2019-nCoV, 2019-CoV, coronavirus, SARS-nCoV-2, urology, cancer, bladder, prostate, kidney, trauma, stone, neurogenic, and reconstructive. The initial search resulted in 495 records. After the primary screening of titles, abstracts, and full texts and removing duplicates, 10 articles were selected and included in this rapid review. Moreover, we performed meta-analysis of binary data for the outcomes with sufficient data. Owing to a high level of heterogeneity because of different study designs and contexts, we used a random model for the meta-analysis. Only 5 studies were eligible for the meta-analysis. In these studies, comprising 964 COVID-19 positive patients, the cumulative event rate of acute kidney injury (AKI) was 7.1% (95% confidence interval: 1.8%–24.5%, p<0.001, I2=92.4). Based on the qualitative synthesis of the 10 included studies, patients with COVID-19 and kidney diseases had higher risk of in-hospital mortality. If AKI occurs because of the novel coronavirus, the mortality rate will be very high. Therefore, we need further investigations and more studies to recognize the extent and the cause of renal involvement in COVID-19.
