Abstract

Chronic interstitial nephritis in agricultural communities (CINAC) is a progressive form of tubulointerstitial nephritis affecting agricultural workers in different parts of the world. Its underlying etiology is not known, although a study by Vervaet and coworkers in this issue of Kidney International provides strong evidence that CINAC is a lysosomal tubulopathy induced by toxin exposure. Key to this important discovery is a thorough morphologic analysis of kidney tissue, including ultrastructural as well as histopathologic examination.
