Abstract:
OBJECTIVE:To investigate the feasibility and safety of substituting tacrolimus(FK506) for cyclosporin A(CsA) on delaying the pace of renal dysfunction in patients with biopsy-proven chronic allograft nephropathy(CAN).
METHODS:Seventy-three renal transplantation patients with CAN proved by allograft biopsy were collected in this study. Patients were randomly divided into 2 groups. Patients were either converted to FK506(FK506 group, n=43) or remained on their initial CsA-based immunosuppression(CsA group, n=30). The clinical data at study entry and after 12 months including blood urea nitrogen(BUN), serum creatinine(SCr), glomerular filtration rate(GFR), 24-hour urine protein excretion, serum total cholesterol(TC), triglyceride(TG), low density lipoprotein(LDL) and the side effects of calcineurin inhibitors were monitored during a follow-up of over 12 months.
RESULTS:Twelve months later, the level of SCr was statistically reduced and GFR levels were obviously elevated in the FK506 group as compared with CsA group [(194.8+/-42.5)micromol/L vs. (245.4+/-52.8)micromol/L and (50.14+/-3.92)mL/(min.1.73 m(2)) vs. (40.58+/-2.49)mL/(min.1.73 m2), P<0.01]. Quantity of 24-hour urine protein excretion in the FK506 group was (2.0+/-0.5)g which is significantly lower than (3.9+/-0.7)g in the CsA group(P<0.01). TC, TG, and LDL levels remained unchanged in the CsA group, while those were statistically reduced in the FK506 group respectively [(5.19+/-0.73)mmol/L vs. (6.94+/-1.37)mmol/L, (1.86+/-0.84)mmol/L vs. (3.14+/-1.38)mmol/L, (3.03+/-0.71)mmol/L vs. (3.82+/-0.89)mmol/L, P<0.01]. Tremor obviously increased (P<0.01) and hypertension obviously decreased (P<0.05) in the FK506 group compared with the CsA group.
CONCLUSION:FK506 treatment can greatly improve the proteinuria and hyperlipidemia. Conversion from CsA to FK506 is an effective and safe alternative therapy for delaying the progression of renal dysfunction induced by CAN.
