A return to normal kidney function in a Caucasian male after COVID-19 induced dialysis-requiring kidney failure
Abstract Background: Coronavirus disease 2019 also known as COVID-19 has been recognized by WHO as a global pandemic and has spread to most of the world. The disease has a multitude of clinical presentations, and especially the development of acute kidney injury has been associated with increased mortality.Case Presentation: A 71-year old Caucasian male was admitted with fever and dyspnea to the emergency department. His medical history included type 2 diabetes and hypertension. Blood tests showed a normal kidney function before admission with a creatinine of 0,8 mg/dL. Clinical examination, blood tests and Chest X-ray suggested COVID-19. At admission the diagnose COVID-19 was confirmed, fluid therapy was commenced and Angiotensin-converting enzyme therapy discontinued. The patients was intubated due to respiratory failures and transferred to the intensive care ward where he developed acute anuric kidney failure and was started in continuous renal replacement therapy. After 6 days of dialysis treatment his kidney function slowly started to improve, and he was discharged after 26 days of admission. 42 days after admission his creatinine was measured to 1.3 mg/dLConclusion: We present the rare case of a Caucasian male, who not only survived COVID-19 induced kidney failure that required continuous renal replacement therapy, but returned to almost baseline creatinine. We discuss the role of Angiotensin-converting enzyme inhibitor treatment in COVID-19 and the potential pathophysiological mechanism surrounding AKI in COVID-19 patients in literature, and connect it to our case report.
