Abstract
Background
Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide and seriously threatens human health since December 2019. However, information about acute kidney injury (AKI) during COVID-19 infection is limited. Some studies thought that presence of AKI is very common and cannot be ignored, while some studies pointed that AKI only is a rare incident during COVID-19 infection. This meta-analysis aimed to find out the truth of COVID-19 related AKI and to provide stronger evidence.
Methods
Two authors independently performed a literature search using PubMed, Web of Science, Embase, and Cochrane Library fulfilled the pre-specified criteria until April 25, 2020 to include studies reported the necessary clinic characteristics, then the incidence of AKI, incidence of required RRT, the mortality with AKI and the death risk with AKI during COVID-19 infection were pooled for statistical analysis by Open Meta-Analyst software to get conclusions.
Findings
It was found that the incidence of AKI in hospitalized patients with COVID-19 infection is low, only about 3.8%; the in-hospital mortality with AKI in COVID-19 infected patients is reach up to 32.6%; the death risk with AKI in COVID-19 infected patients is about 16.1 times higher than those without AKI.
Conclusions
This meta-analysis indicated AKI during COVID-19 infection should be pay more attention, it maybe a strong red flag to death risk. It is still need additional studies to support the conclusions and to explore the AKI mechanism during COVID-19 infection.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:The present study provides a much-needed evidential basis for AKI incidence among COVID-19 patients, but has several limitations. First, there remains a limited amount of original studies (< 10) by which to evaluate the risk of death with AKI during COVID-19 infection. Nonetheless, considering the potential of this research in advancing our understanding of COVID-19 and in supplying medical practitioners with evidence-based recommendations, and in light of the current global pandemic emergency, the authors took the decision to present these findings forthwith. Second, there is a statistically significant heterogeneity in the meta-analysis for AKI incidence. Potential origins for significant heterogeneity may come from different COVID-19 infection stages. As performed via subgroup analysis according to AKI definitions, the results still reveal a significant heterogeneity. Future heterogeneity exploration must rely on the acquisition of more original clinical data. Finally, since the clinical data collection is based upon publications with limited availability, extra investigations could not be made but should be considered (infection duration, drugs used, geography, ethnicity, and age group in particular). Nevertheless, AKI incidence with COVID-19 infections must demand greater attention. Further studies are still urgently needed to support the conclusion herein and explore the AKI mechanism within a COVID-19 infection context. Although the chance of AKI during COVID-19 is rar...
