Abstract
Background: The aim of this study was to evaluate renal function by urinalysis in COVID-19 patients following the administration of vancomycin.
Methods: A retrospective observational study was performed between October 2020 and January 2021, during which time patients were hospitalized in the Prince Mohammed Bin Abdulaziz Hospital in Riyadh, Saudi Arabia. The patients were free of kidney disease. Urinalysis was performed by an automated laboratory system, and the collected results were based upon age, gender, diabetic status, whether the patients had received vancomycin, the mortality rate, and the urinalysis panel including coinfection by bacteria and yeast.
Results: A total of 227 patients were included in this study, 147 (64.75%) of whom were male and 80 (35.25%) of whom were female; 54.63% were diabetic, 11.89% were prediabetic, and 33.48% were non-diabetic patients. Proteinuria, hematuria, glycosuria, coinfection, and ketonuria were detected among all participants within the study group, specifically among diabetic patients. The mortality rate was 16.2% among the study group; 6.6% had received vancomycin, and 9.6% had not received vancomycin. No significant correlation was found between nephrotoxicity and abnormalities in the urine and the mortality rate among members of our study group.
Conclusions: Proteinuria, hematuria, glycosuria, ketonuria, and coinfection were common among members of our study group, especially in the diabetic group. Urinalysis abnormalities were less frequent in the vancomycin group than in the others, except the prediabetic group. No correlation between mortality and vancomycin was identified.
