Acute kidney injury profile of COVID-19 patients and associated risk factors a rural hospital-based retrospective study from Vadodara, Gujarat

Abstract

Background: Clinical outcome of patients hospitalized with COVID-19 and acute kidney injury (AKI) are not well understood. The clinical significance of abnormal electrolytes and renal outcome in COVID-19 patients have been poorly documented. We aim to exhibit the electrolyte abnormalities, renal outcome and associated risk factors in hospitalized COVID-19 patients in rural tertiary care hospital in Vadodara district, Western India. Method: A hospital record based retrospective study was conducted. Total 994 patients hospitalized with COVID-19 between 1st April 2021 to 30th June 2021 and those meeting inclusion criteria were included for the analysis. The laboratory data of interest included electrolytes reports like Na+, K+, CL-, creatinine and blood urea. Result: Of the total hospitalized COVID-19 patients, 324 patients were eligible. For the criteria for suspected AKI - 279 (86.11%) and no AKI - 45 (13.88%) patients were found. Suspected AKI patients were classified into four conditions: 1) HYPERNATREMIA (14.33%); HYPERKALEMIA (2.15%); BCR ratio >20 (65.59%); HIGH Cl- (17.92%). Out of total AKI patients, (36.91%) died whereas (13.3%) patients died in no AKI group. All patients were provided antibiotics, steroids and anti-viral therapies irrespective of AKI status, which we presume might have contributed in high mortality among suspected AKI.
