Urine Alkalinisation to Prevent AKI in COVID-19

GSTT COVID-AKI

Since the outbreak of coronavirus disease 2019 (COVID-19), more than 100,000 patients have died in the United Kingdom. Acute kidney injury is common in critically ill patients with COVID-19. It is associated with a high risk of dying. At present, it is not clear how to prevent or treat kidney failure in these patients. Recent research has shown that the coronavirus can directly infect kidney issue. It uses a particular protein on the cell surface (the ACE2 receptor) for entry into cells. Entry into cells is easier if the blood is more acidic. The aim of this project is to find out whether urinary alkalisation using intravenous bicarbonate is feasible and can reduce the risk of acute kidney injury in critically ill patients with COVID-19.
