COVID-19 Linked to Kidney Stone Disease
Researchers from the University of Louisville have discovered that the coronavirus disease 2019 (COVID-19) pandemic may be causing kidney stone disease (KSD) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced epigenetic reprogramming. This review proposes a novel framework connecting COVID-19-induced epigenetic reprogramming to disruptions in mitochondrial sulfur metabolism and the pathogenesis of kidney stones.
Key Takeaways:
- COVID-19 has brought to light unexpected complications beyond respiratory illness, including effects on kidney function and a potential link to kidney stone disease (KSD).
- The researchers propose a novel framework connecting COVID-19-induced epigenetic reprogramming to disruptions in mitochondrial sulfur metabolism and the pathogenesis of kidney stones.
- SARS-CoV-2 interferes with host methylation processes, leading to elevated homocysteine (Hcy) levels and impairment of the trans-sulfuration pathway mechanisms particularly relevant in metabolic disorders such as homocystinuria.
- The study suggests that these epigenetic and metabolic alterations may promote specific kidney stone subtypes through disrupted sulfur and oxalate handling.
- The research also explores the role of COVID-19-associated gut dysbiosis in increasing oxalate production and driving calcium oxalate stone formation.
- The study offers an integrated hypothesis to explain post-viral renal lithogenesis and highlights the potential of targeting sulfur metabolism and redox pathways as therapeutic strategies for KSD triggered or aggravated by viral infections such as COVID-19.
