OBJECTIVE: Clinical studies have demonstrated that tubulointerstitial rather than glomerular pathology correlates with the degree and progression of renal impairment. Urinary n-acetyl-betaD- glucosaminidase (NAG) is a biomarker of tubular damage, shown to be elevated in patients with glomerulonephritis and acute kidney injury. However, it has not been assessed longitudinally in chronic kidney disease (CKD). The aim of the present study was to determine urinary NAG activity and its possible associations with metabolic and inflammatory parameters in CKD.
