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:

Background and objectives

Some biomarkers of renal tubular injury are reported to be useful for predicting renal prognosis in the early stage of diabetic nephropathy (DN). Our study compared predictions of the renal prognosis by such biomarkers and by histologic tubulointerstitial damage.

Design, setting, participants, & measurements

Among 210 patients with type 2 diabetes and biopsy-proven DN managed from 1985 to 2011, 149 patients with urinary N-acetyl-β-d-glucosaminidase (NAG) and urinary β2-microglobulin (β2-MG) data at the time of renal biopsy were enrolled. The primary outcome was a decline in eGFR of ≥50% from baseline or commencement of dialysis for ESRD.

Results

The median follow-up period was 2.3 years (interquartile range, 1.1-5.3), and the primary outcome
