ABSTRACT
BACKGROUND:
Chronic allograft nephropathy (CAN) is commonly associated with proteinuria. In native nephropathies, proteinuria is linked with proximal renal tubular damage. This study uses regression analysis to link proteinuria with urinary N-acetyl-beta-d-glucosaminidase (NAG) as a marker of tubular injury or hyperfunction in renal transplant patients.METHODS:
Proteinuria and urinary NAG were measured and regression analysis applied in 105 transplant patients (42 with CAN). Most were receiving calcineurin inhibitor-based immunosuppression (cyclosporine, n=60; tacrolimus, n=26; and neither drug, n=19). Patients with native nephropathies (n=96) and volunteers (n=21) were also studied.RESULTS:
Urinary NAG increased with increasing proteinuria. However, patients taking calcineurin inhibitors had higher urinary NAG at any level of urinary protein than those on alternative therapy, or in native nephropathies.CONCLUSIONS:
In groups of transplant patients taking different immunosuppressive regimens, regression analysis of urinary NAG against urinary protein can identify the separate effects of drug-related tubular injury or hyperfunction from that of proteinuria.
