Abstract
Since June 1985 ten consecutive paediatric cadaveric renal transplant recipients (aged from 7 to 15 years) have been studied prospectively to evaluate a triple immunosuppressive regime of low-dose cyclosporin A (CyA), azathioprine (AZA) and prednisolone (PNL) with the aim of eliminating PNL from the regime within 6 months. Follow-up has been over 6–18 months. Patient and graft survival are both 100%. Median (range) serum creatinine values at 6 months were 0.09 (0.05–0.14) mmol/l (n=10) and 0.09 (0.06–0.16) mmol/l (n=5) at 12 months. Readily reversible acute rejection episodes occurred in five patients (50%); two of these episodes occurred soon after cessation of PNL. Six months post-transplantation, PNL had been discontinued in six patients (60%). After 12 months, three of five patients were still not receiving PNL. Complications included hypertension (seven patients), cytomegaloviral infections (three patients), labial herpes simplex (one patient), leucopenia (two patients), marked hirsuitism (four patients) and transient CyA nephrotoxicity (one patient). Following transplantation, all children had growth velocities greater than 5 cm/year and seven have growth patterns which suggest that “catch-up growth” may be occurring. This preliminary study shows that a triple immunosuppressive regime of low-dose CyA, AZA and PNL allows excellent patient survival, graft survival and graft function and has been associated with few complications, including a low incidence of CyA nephrotoxicity. Growth rates are very encouraging and in a high proportion of children it has been possible to discontinue PNL completely.
