Brief summary
Systemic infection is still a major concern in young children with liver transplantation. The approach of this study is to reduce the risk of systemic infections by avoiding intraoperative steroids (another class of immunosuppressive drugs) given in combination with basiliximab, cyclosporine and steroids in pediatric de novo liver transplant recipients. The treatment is compared to the same treatment regimen including intraoperative steroids with respect to rejection episodes.
Interventions
Basiliximab (10 mg) was supplied as a lyophilisate in vials with ampoules of sterile water for injection (5 mL) and had to be given of 10 mg (body weight \<35 kg) or 20 mg (body weight ≥35 kg) strength.
Cyclosporine/cyclosporine microemulsion had to be started with 100 mg/m²/day intravenous (i.v) (2x4h) for 7 days and was to be continued i.v. or orally from day 8 onwards as per center practice. During the 6 months treatment period Cyclosporine doses had to be adjusted according to Cyclosporine A (CsA)-trough levels.
Intravenous prednisolone (loading dose: 300 mg/m2, maximum 500 mg) had to be administered intraoperatively only in treatment arm 1 (day 0). The first dose of steroids in treatment arm 2 (day 0) had to be administered within 8 hours after reperfusion of the graft. Beginning from day 1 to day 6 doses of 15 mg/m2/day had to be given intravenously (i.v.) in both treatment arms. Then, the steroid doses (oral prednisone or its equivalent) were to be decreased from 10 mg/m²/day orally (day 7-13), to 7.5 mg/m²/day orally (day 14-30), to 4 mg/m²/day orally (until end of month 2), to 2.5 mg/m²/day orally (until end of month 3) and to 1 mg/m²/day orally (until end of month 6).
