A decrease in the urinary levels of TFF3 is associated with acute kidney injury in animal models. Circulating serum TFF3 is significantly increased Midostaurin in patients with chronic kidney disease (CKD) in a recent report. However, whether the urinary levels of TFF3 are associated with renal dysfunction in patients with CKD is unclear. Methods: We analyzed the urinary TFF (uTFF) levels in spot urine samples from 216 patients with CKD, and assessed the relationships among the uTFF, proteinuria and kidney function. Patients were prospectively followed for three years for doubling of the baseline serum creatinine concentration much and the initiation of renal replacement therapy. Results: The excretion of uTFF3 significantly increased with the extent of albuminuria (P < 0.0001), urinary α1 microglobulin (P < 0.0001) and urinary β2 microglobulin (P < 0.0001) and the decline in the eGFR (P < 0.0001). A multivariate logistic regression analysis

showed that the patients with higher levels of uTFF3 were more likely to have CKD stage ≥G3b (P < 0.01). A longitudinal analysis demonstrated that patients with a higher uTFF3, in combination with macroalbuminuria, had a significantly worse renal prognosis (Log rank, P < 0.0001). The levels of urinary TFF3 in the renal end-point group were significantly higher than those in the renal survival group (P < 0.01). The AUC of uTFF3 for predicting the progression of CKD (0.879) was significantly higher than that of albuminuria (0.692) (P < 0.0001). The levels of uTFF1 and uTFF2 did not correlate with albuminuria. Conclusions: The excretion of uTFF3 is therefore significantly associated with albuminuria and a decline in the renal function. Moreover, the uTFF3 level can be used as a novel biomarker to predict the renal outcomes in CKD patients.
