Chronic kidney disease represents a significant and underrecognized consequence of SARS-CoV-2 infection, with multiple studies demonstrating elevated CKD risk persisting months after initial COVID-19 recovery. The virus triggers a distinctive nephropathy characterized by collapsing focal segmental glomerulosclerosis, alongside increased rates of new-onset vasculitis affecting renal function. This bidirectional relationship creates particular vulnerability for existing CKD patients, who face heightened risks of both severe acute COVID-19 and prolonged post-infectious complications. The kidney involvement extends beyond typical post-viral sequelae, suggesting direct pathophysiological mechanisms rather than secondary inflammatory damage alone. For the growing population of long COVID patients, this represents a critical blind spot in current monitoring protocols. Most post-COVID care focuses on respiratory and neurological symptoms, potentially missing progressive kidney dysfunction that develops silently over months. The finding challenges assumptions about COVID-19 as primarily a respiratory illness and underscores the need for systematic nephrology screening in long COVID clinics. Given that CKD affects quality of life and longevity trajectories, early detection and intervention could significantly alter health outcomes for millions of COVID survivors experiencing persistent symptoms.
