Proteinuria as a Noninvasive Marker for Renal Allograft Histology and Failure: An Observational Cohort Study.

ABSTRACT: Proteinuria is routinely measured to assess renal allograft status, but the diagnostic and prognostic values of this measurement for renal transplant pathology and outcome remain unclear. We included 1518 renal allograft recipients in this prospective, observational cohort study. All renal allograft biopsy samples with concomitant data on 24-hour proteinuria were included in the analyses (n=2274). Patients were followed for ≥7 years post-transplantation. Compared with proteinuria <0.3 g/24 h, the hazard ratios for graft failure were 1.14 (95% confidence interval [95% CI], 0.81 to 1.60; P=0.50), for proteinuria 0.3-1.0 g/24 h, 2.17 (95% CI, 1.49 to 3.18; P<0.001), for proteinuria 1.0-3.0 g/24 h, and 3.01 (95% CI, 1.75 to 5.18; P<0.001), for proteinuria >3.0 g/24 h, independent of GFR and al
