Acute Kidney Injury in Patients with COVID – 19 Infection: Α Tertiary Referral Hospital Experience

The emersion of the new coronavirus SARS COV 2 (Severe Acute Respiratory SyndromeCoronavirus 2) was rapidly characterized as a pandemic by WHO. The majormanifestation of the virus is respiratory distress; however, the involvement of other organsshould not be overlooked. The kidney is one of the most important target organsof the specific virus with acute kidney injury (AKI) described in 5-36% of COVIDpositive patients and an average 25% within the severely ill.Purp ose: The purpose of this study was to consider the incidence of AKI in patientswith COVID 19 in our cohort and to better understand risk factors associated withAKI. Further, we wanted to investigate the impact of AKI on survival and in hospitalmortality.Methods: Patients admitted to Evagelismos General Hospital with confirmed COVID-19 infection from 11th March until 22th May were investigated. Patients 18 yearsold as well as transplanted patients were excluded from this study. AKI was definedaccording to the AKI criteria.Results : From 99 patients with COVID-19 infection, AKI occurred in 41 (41.4%).A total of 44 patients (44.4%) were admitted to Intensive Care Unit (ICU) and 31 ofthem (70.5%) developed AKI. Of the 44 patients with AKI, 16 (39%) required renalreplacement therapy. Hospital mortality, in total, was 16.2% (37% among patientswith AKI versus 0.02% among those without AKI, p=0.000).Conclusion: AKI was common among patients hospitalized with COVID 19. AKIwas associated with older age, clinical severity and existing CKD
