Abstract:
Objective To explore the relationship between urine TGF-? 1 concentration and long-term function of renal allograft. Methods From August 1, 1999 to December 30, 2000, the urinary content of TGF-? 1 was determined in 146 patients who had had renal transplantation one year ago but with normal renal function. The relative content of urine TGF-? 1 was 172.5～533.1pg/mg Cr. Forty patients each with higher or lower urine TGF-? 1 concentrations were selected to form group Ⅰ and Ⅱ. Two years later, renal function variables, blood and urine TGF-? 1 concentrations were compared between the two groups. The relation between urine TGF-? 1 and chronic allograft nephropathy (CAN)was assessed. Biopsies of transplanted kidneys were carried out in recipients whose creatinine was higher than normal. Results Three years after transplantation, creatinine clearance rate was lowered by 12.8?10.6ml/min in group Ⅰ patients, and 29.6% of them were diagnosed as CAN. Compared with group Ⅱ, the lowering of creatinine clearance rate was more intense and the incidence of CAN was higher, with obviously higher urinary TGF-? 1 content. The differences were significant. Conclusions TGF-? 1 may play a role in the pathogenesis of CAN after renal transplantation, and urinary TGF-? 1 may be considered as an indicator in assessing long term renal function in such case.
