Toxic nephropathy is a disorder whose primary feature is impairment of the normal functions of the kidney. The clinical manifestations of toxic nephropathy vary from a mild reduction in renal function to hematuria, proteinuria, and urolithiasis to a severe progressive toxicity culminating in end-stage renal disease. Although it is commonplace for adolescents to use supplemental treatments such as natural medicines and over-the-counter (OTC) analgesics, they do not often reveal the use of such treatments to physicians, nor do they fully understand their potential adverse effects. This article reviews the nephrotoxic effects of OTC analgesics, natural medicines, and illicit drugs.

Functional nephrons can be lost through a process of glomerulotubular disconnection. Progressive development of atubular glomeruli seems to play a major role in a number of renal disorders, including glomerular diseases, ascribed to injury to the glomerulotubular junction as a result of proteinuria; however, formation of atubular glomeruli is even more common in tubulointerstitial disorders, such as obstructive nephropathy. Toxic nephropathy is also associated with the formation of atubular glomeruli, suggesting susceptibility of the glomerulotubular junction to toxic injury. Narrowing or other abnormalities of the glomerulotubular junction are described as precursors of glomerulotubular disconnection. Cystinosis represents a dramatic example of progressive injury to the glomerulotubular junction, with formation of the "swan-neck deformity" following degenerative tubular cell changes attributable to apoptosis. Significant numbers of atubular glomeruli have been reported in chronic pyelonephritis and renal allograft rejection; this suggests interstitial inflammation as a stimulus for the formation of atubular glomeruli. Because of difficulties in morphologic recognition, it is likely that glomerulotubular disconnection is an underappreciated mechanism in the progression of renal disease. A better understanding of the vulnerability of the glomerulotubular junction and its protection from injury should lead to better strategies for preserving renal function in many nephropathies.
