Overview

Nephrologic_Disorders of COVID-19

Nephrologic_Disorders risk factors of COVID-19

Complications

AKI

Pathophysiology

  • Angiotensin-converting enzyme 2 (ACE2), which is a primary receptor for SARS-CoV-2 entry into cells, mostly presents in renal tubular epithelial cells as well as lungs and heart.[1]
  • Despite kidney injury following COVID-19 infection is less frequent than severe lung injury, ACE2: ACE ratio is higher in the kidneys compared to the respiratory system. (1:1 in the kidneys VS 1:20 in the respiratory system)[1]
  • After SARS-CoV-2 enters through the nasal cavity, it may travel to the kidneys and enters the bloodstream leading to severe inflammatory response activation and cytokine storm.
  • It is thought that AKI following COVID-19 is the result of[1]
    • Sepsis
    • Hypovolemia and Hypotension
    • Hypoxemia
    • Blood clots formation, leading to impaired blood flow in the renal arterioles.
  • AKI often occurs at later stages in critically ill patients with COVID-19 following multiple organ failure.

Clinical Features of AKI by SARS-CoV-2

  • Patients in the early stages of kidney failure may be asymptomatic. If left untreated, patients may progress to develop Azotemia and Uremia, which occur due to the buildup of waste materials in the blood.
  • Symptoms of kidney injury include[2]:
    • Nausea and Vomiting
    • Weakness
    • Fatigue
    • Confusion
    • Weight loss
    • Loss of appetite
    • Oliguria or Anuria
    • Fluid retention, leading edema and swelling of face, extremities
    • Electrolyte imbalance; High level of Potassium which leads to cardiac arrhythmia

Treatment

  • Management of AKI following COVID-19 includes treatment of infection, identifying electrolyte disorders, and intravenous fluid administration.
  • Treatment of AKI following COVID-19 includes[3]:
    • Correction of hypovolemia and hypotension by the administration of adequate intravenous fluid
    • Correction of electrolyte disturbances
    • Renal Replacement Therapy
      • If AKI is unresponsive to conservative therapy
      • In volume overload conditions
      • Modality of choice in unstable hemodynamic status
    • Anticoagulants in hypercoagulable conditions
    • Sequential extracorporeal therapy
