Abstract:
Objective To investigate the effect of swifch from cyclosporine to FK506 on renal allograft outcome after initial acute rejection. Methods Clinical outcome of patients who experienced first acute rejection episode were retrospectively analyzed. After initial acute rejection, 23 patients were switched to FK506-based immunosuppression, and 63 patients continued CsA-based immunosuppression. Demographic data, lipid, serum creatinine, uric acid, incidence of recurrent acute rejection and graft survival were analyzed and compared. Results During one year after anti-rejection therapy, incidence of biopsy-proved recurrent rejection events was significantly lower with FK506 therapy (1/23, 4.35%) compared with CsA therapy (16/63, 25.40%)(P=0.033). 5-year graft survival rate of FK506-based immunosuppression group was higher than that of CsA-based immunosuppression group (100.0% vs 81.4%). Serum uric acid level of FK506-based immunosuppression group from 24 months to 36 months after initial rejection were significantly lower than that of CsA-based immunosuppression group [(265.5 ±147.9) μmol/L, (245.8±88.9) μmol/L vs (428.5±119.3) μmol/L, (441.2±125.3) μmol/L, P<0.01, respectively]. Conclusion Conversion to FK506 therapy can significantly reduce recurrent rejection episode, and decreasing serum uric acid level provides long-term benefits to graft survival.
