Effect of novel coronavirus disease 2019 infection on chronic kidney disease G1-G5, G5 Dialysis and G5 Transplantation
Abstract Background: The pneumonia caused by the 2019 novel coronavirus (SARS-CoV-2) is a highly infectious disease that causes lethal disease and multiorgan failure. The aim of this research is to investigate association between covid-19 infection and kidney dysfunction.Methods and materials: In this retrospective study, sixty-eight patients with kidney dysfunction and covid-19 infection were investigated. Clinical features, laboratory data at initial presentation, management and outcomes were collected.The paper has written based on searching PubMed Central and Google Scholar to identify potentially relevant articles. Median, percentage, mean ± standard deviation (SD), two-tailed t and chi-square and Cohen᾽s-d tests were used for statistical analyses. Moreover, relative risk, odds ratio, pearson᾽s correlation for statistical analyses were used. Results: The average age of patients at time of diagnosis in covid-19 nephropathy was 52.04 ± 14.42 years (ranging from 24 years to 88 years). There was not statistical significance correlation between lymphocytopenia and serum creatinine (SCr) in covid-19 nephropathy (R2=0.063; p-value= 0.33). Effect size of elevated IL-6 on decreased estimated glomerular filtration rate (eGFR) in covid-19 nephropathy was assessed 0.656 (medium effect size). Relative risk and odds ratio of acute kidney disease (AKD) in covid-19 nephropathy were assessed 0.57 and 0.4, respectively (p-value: 0.422). Correlation between SCr changes and time of emergent AKI (acute kidney injury), AKD and chronic kidney disease (CKD) was assessed with R2 of 0.0003 and p-value of 0.94 (not significant). Conclusion: The present study revealed medium effect size of elevated IL-6 on decreased eGFR. Future clinical research is required for investigating novel unknown findings in covid-19 nephropathy.
