AbstractAcute kidney injury (AKI) is relatively common in critically ill coronavirus disease 2019 (COVID-19) patients and it increases mortality and prolongs hospital stay. This article aimed to investigate the history, virology, epidemiology, clinical manifestations, pathophysiology and management of COVID-19 disease, in general, and the pathogenetic mechanisms of severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV2)-induced kidney damage, in particular. Keywords like SARS-CoV2, COVID-19, renal impairment, sepsis, viremia, etc. were used to find relevant publications from PubMed, Scopus, Google Scholar, and clinical trials registry websites. According to different studies, kidney involvement in COVID-19 typically occurs in patients who develop acute respiratory distress syndrome (ARDS) or multiorgan failure. The kidney damage in COVID-19 has been shown to be multifactorial, involving direct viral infection, indirect injury by sepsis, hemodynamic alterations, cytokine storm, disseminated intravascular coagulation and other unknown mechanisms. The presence in kidney of angiotensin-converting enzyme 2 (ACE2), a receptor for the virus, has been proven, but few cases of direct viral presence in kidney tissue have been published. Therefore, further studies are needed to investigate the exact mechanisms underlying kidney impairment. Since the development of AKI is one of the important risk factors for mortality in COVID-19 patients, optimal management of AKI may improve the outcomes. Key Words: Acute kidney injury, Angiotensin-converting enzyme, Sepsis, Cytokine storm, Kidney replacement therapy, Coronavirus disease 2019.
