Insights
Cyclosporin A (CsA) offers better long-term patient and graft survival after pediatric renal transplantation compared to azathioprine (AZA). While CsA showed lower graft function, it did not progressively decline over time.
Area of Science:
- Pediatric Nephrology
- Transplantation Immunology
- Pharmacology
Background:
- Long-term outcomes of immunosuppression in pediatric renal transplantation are crucial.
- Cyclosporin A (CsA) and azathioprine (AZA) are standard immunosuppressants.
- Assessing the long-term effectiveness and tolerability of CsA in children is important.
Purpose of the Study:
- To compare the long-term effectiveness and tolerability of CsA versus AZA in pediatric renal transplant recipients.
- To evaluate patient and graft survival rates, rejection episodes, and graft function.
Main Methods:
- Retrospective analysis of 32 children treated with CsA and low-dose prednisolone.
- Comparison with 34 children treated with AZA and high-dose prednisolone.
- Both groups had functioning grafts for at least 5 years post-transplantation.
Main Results:
- Overall patient and graft survival rates were significantly better in the CsA group.
- The CsA group experienced more late acute reversible rejection episodes (6 vs. 2).
- Graft function was lower in CsA recipients but showed no progressive decline.
Conclusions:
- CsA demonstrates superior long-term patient and graft survival in pediatric renal transplantation.
- Despite lower graft function, CsA's stability mitigates concerns about progressive loss.
- CsA is a viable long-term immunosuppressive option for children post-renal transplant.
Abstract:
In order to assess the long-term effectiveness and tolerability of cyclosporin A (CsA) treatment in children with renal transplantation (Tx), the follow-ups of 32 children (17 boys, 15 girls; age at Tx = 12.2 yr; range, 5.1 to 16.9) with a functioning graft of greater than or equal to 5 yr and continuous treatment with CsA and low-dose prednisolone are analyzed retrospectively. For comparison, data of 34 children (19 boys, 15 girls; age at Tx, 11.0; range, 3.2 to 17.1) are collected who had received a graft before the introduction of CsA, had at least 5 yr of graft function, and were continuously treated with azathioprine (AZA) plus high-dose prednisolone. The mean observation period in the CsA group was 6.5 (range, 5.0 to 8.0) yr, and in the AZA group was 10.4 yr (range, 5.7 to 15.8). CsA dosage remained unchanged in the range of 200 mg/m2/day; CsA whole blood trough level was 120 to 130 ng/mL throughout the years. One patient died in each group. Four more grafts were lost in the CsA group by chronic rejection, which was associated with noncompliance in three, and two grafts were lost in the AZA group by chronic rejection. Late acute reversible rejection episodes occurred more frequent in the CsA (six) than in the AZA group (two). The overall survival rates for patients and grafts were significantly better with CsA. The graft function in CsA-treated recipients was significantly lower than that in AZA patients, but there was no progressive loss over the years.(ABSTRACT TRUNCATED AT 250 WORDS)
