The Product of Duration and Amount of Proteinuria (Proteinuria Index) Is a Possible Marker for Glomerular and Tubulointerstitial Damage in IgA Nephropathy

Abstract

The natural course of IgAN is steadily progressive depending on the duration and amount of proteinuria. The product of these two factors (proteinuria index) may be a useful predictor for glomerular and interstitial histopathological changes and the fate of renal function in IgAN.
