IS MEMBRANOUS NEPHROPATHY ONLY A GLOMERULAR-DISEASE

Tubulointerstitial lesions represent nor only a constant component of the pathology of a ''classical'' glomerular disease such as idiopathic membranous nephropathy but also the most important prognostic indicat or and a new ''target'' for its treatment. Proper ''quantification'' o f the cellular events occurring within the interstitium may enable us to accurately assess the amount of disease activity and identify patie nts who might benefit from treatment.
