Eight-Year Results of the Spiesser Study, a Randomized Trial Comparing de Novo Sirolimus and Cyclosporine in Renal Transplantation
Résumé
We present the results at 8 years of the Spiesser study, a randomized trial comparing de novo sirolimus and cyclosporine in kidney transplant recipients at low immunologic risk. We assessed estimated glomerular filtration (eGFR), graft, patient, and death-censored graft survival (log-rank compared), de novo DSA appearance, risk of malignancy, post-transplant diabetes mellitus (PTDM), and anemia. Intent-to-treat and on-treatment analyses were performed. Graft survival was similar in both groups (sirolimus: 73.3%, cyclosporine: 77.7, P = 0.574). No difference was observed between treatment groups concerning patient survival (P = 0.508) and death-censored graft survival (P = 0.858). In conditional intent-to-treat analysis, mean eGFR was greater in sirolimus than in cyclosporine group (62.5 ± 27.3 ml/min vs. 47.8 ± 17.1 ml/min, P = 0.004), in particular because graft function was excellent in patients maintained under sirolimus (eGFR = 74.0 ml/min). Importantly, no detrimental impact was observed in patients in whom sirolimus has been withdrawn (eGFR = 49.5 ml/min). Overall, 17 patients showed de novo DSAs, with no difference between the two groups (P = 0.520). Malignancy did not differ by treatment. An initial maintenance regimen based on sirolimus provides a long-term improvement in renal function for kidney transplant patients, especially for those maintained on sirolimus.
