AKI with COVID-19

Acute kidney injury in patients with COVID-19 (May 2020)


Acute kidney injury in patients with COVID-19 (May 2020)

AKI has been reported among ptns infected with the coronavirus disease 2019 (COVID-19), but the available database on its current incidence and its clinical criteria have been limited owing to the small number of patients. In an observational report conducting 5500 patients who admitted with COVID-19 infection, AKI occurred mostly in 37 %, with 14 % of cases were in need for dialysis (DX). Almost 50% of the ptns with AKI presents with hematuria and proteinuria syndrome, and about one1/3rd were diagnosed with AKI within 24 hs of hospital admission. AKI has been observed in 90 % of ptns requiring mechanical ventilation and in 22 % of non-ventilated ptns. The current findings raise the postulation that AKI is a common sequela of COVID-19, furthermore, it can be recognized as an important marker of clinical disease severity.

Effect of sodium bicarbonate on post-contrast acute kidney injury among patients receiving intravenous contrast (April 2020)

Ptns with an estimated glomerular filtration rate (eGFR) of <30 mL/min/1.73 m2 have a higher risk of acute kidney injury (AKI) following intravenous iodinated contrast used for computed tomography (CT). By contrast, the risk is not appreciably increased among ptns with a higher eGFR, consequently, it is NOT recommended to apply the policy of prophylactic volume expansion in such cohort of ptns. In a trial conducting over 550 ptns with mild/ moderate chronic kidney disease (eGFR ≥30 mL/min/1.73 m2) who underwent CT with IV contrast, post-contrast AKI can be observed at similar rates among cohorts receiving, and not receiving prophylactic volume expansion with intravenous sodium bicarbonate. These findings support the recommendation that volume expansion should be NOT administered to prevent post-contrast AKI in ptns with an eGFR ≥30 mL/min/1.73 m2.
