Abstract
- For the early detection of abnormal findings considering for therapeutic intervention, we regularly undertake protocol renal allograft biopsy at 1 year after kidney transplantation (KT). We examined whether urinary liver fatty acid binding protein (L-FABP) level predicts some pathologic findings of renal allograft. We retrospectively enrolled recipients with stable graft function who routinely were biopsied renal allograft specimens 1 year after KT between January 2015 and May 2021 in our center. We assessed the association urinary L-FABP level with pathologic findings of renal allograft biopsies. We enrolled 56 recipients in this study. Their median age at KT was 49.5 and their median serum creatinine at 1 year after KT was 1.22 mg/dL. In 9 of 56 patients, abnormal high value of urinary L-FABP were observed. All of them had abnormal findings pathologically in the renal allografts (border line change 3, medullary ray injury [MRI] with calcineurin inhibitor toxicity [CNI-T] 1, MRI without CNI-T 1, CNI-T with IgA deposition 1, and BK virus nephropathy 3). On the other hand, 30 of 47 patients with normal value of urinary LFABP had no pathologically abnormal findings. Both specificity and positive predictive value of urinary L-FABP for pathologic findings were 100.0༅. Our results suggest that patients with renal transplant with elevated urinary L-FABP levels might benefit from renal allograft biopsy. Comparison of urinary liver fatty acid binding protein level and pathologic biopsy findings 1 year after KT. [ABSTRACT FROM AUTHOR]
