COVID-19 and Kidney Disease: A Review of Research Findings

Strategic Insights -

Researchers from the University Health Network have investigated the relationship between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and chronic kidney disease (CKD). Their study, published in the International Journal of Molecular Sciences, highlights the over 200 host genes that may influence the severity of COVID-19 and suggests that kidney disease may modulate the expression of SCARF genes and other key host genes involved in an effective adaptive defense against coronaviruses. The researchers propose a research agenda focusing on CKD to develop comorbidity-specific targeted therapeutic approaches to SARS-CoV-2 infection or future coronavirus infections.

Key Takeaways:

  • Chronic kidney disease (CKD) is the most common risk factor for severe COVID-19 and increases the risk of COVID-19-related death.
  • CKD patients are at increased risk of death from multiple infections, to which immune deficiency in non-specific host defenses may contribute.
  • COVID-19-associated acute kidney injury (AKI) has specific molecular features and CKD modulates the local (kidney) and systemic (lung, aorta) expression of host genes encoding coronavirus-associated receptors and factors (SCARFs).
  • The researchers identified over 200 host genes that may influence the severity of COVID-19, including SCARF genes and other key host genes involved in an effective adaptive defense against coronaviruses.
  • Kidney disease may modulate the expression of SCARF genes and other key host genes, which SARS-CoV-2 hijacks to enter cells and replicate.
  • The researchers propose a research agenda focusing on CKD to develop comorbidity-specific targeted therapeutic approaches to SARS-CoV-2 infection or future coronavirus infections.

Statistics:

  • Approximately 7 million persons worldwide have died from COVID-19.
  • CKD is the most common risk factor for severe COVID-19.
  • The researchers identified over 200 host genes that may influence the severity of COVID-19.
  • COVID-19-associated AKI has specific molecular features and CKD modulates the local (kidney) and systemic (lung, aorta) expression of host genes encoding SCARFs.
