Renal Manifestations of Systemic Illness in Children

Kidney disease may be associated with a systemic disorder or found in isolation. With advances in the understanding of the pathophysiology of glomerular disorders, the distinction between primary and secondary glomerular disease is no longer valid. A wide spectrum of glomerular, vascular, and tubulointerstitial diseases may accompany autoimmune disorders, nephritogenic pharmaceuticals, infections, or complement dysregulation. This article focuses on renal manifestations of systemic diseases such as vasculitis, drug- and infection-related tubulointerstitial injury, and thrombotic disorders.
