Prognostic Value of Tubulointerstitial Lesions, Urinary N-Acetyl-β-D-Glucosaminidase, and Urinary β2-Microglobulin in Patients with Type 2 Diabetes and Biopsy–Proven Diabetic Nephropathy

Abstract

Adding urinary NAG and β2-MG excretion to known promoters of progression did not improve prognostication, whereas adding the IFTA score did. The IFTA score may be superior to these tubulointerstitial markers for predicting the renal prognosis in advanced DN.
