INTRODUCTION: SARS-CoV-2 infection can affect other organs aside from those of respiratory system, particularly the kidney, heart, blood, digestive tract, and nervous system. COVID-19 renal compromise consists of different syndromes since proteinuria, hematuria, and acute kidney injury (AKI), until chronic kidney disease. Since COVID-19-induced renal tubular damage has been described as a potential antecedent condition to AKI installation, it was decided to evaluate how COVID-19 affects tubular function. MATERIALS AND METHOD: Serum inflammatory parameters, urinalysis, and classical urinary indexes in COVID-19 admitted patients who had neither AKI nor chronic kidney disease (CKD) were evaluated. Statistical analysis was performed by applying Student t test. RESULTS: Renal tubular function was evaluated in 41 COVID-19 admitted patients who had neither AKI nor CKD. Patients' mean age was 56 years, males (79%), and with normal creatininemia (0.8 +/- 0.2 mg/dL) and eGFR (105.7 +/- 6.5 mL/min) values. It was found mild hypocalcemia and a relative increased fractional excretion (FE) of sodium, FE of calcium, FE of phosphorus, calcium-creatinine index, urinary osmolarity, and relative alkaline urine pH values. CONCLUSION: Tubular dysfunction was documented in COVID-19 patients.
