The authors examined renal allograft loss and hospitalization for RTx biopsy or rejection before and after transition to adult care using clinical and administrative health records of children who underwent RTx (1992-2002) in Ontario, Canada.  Life-table analyses examined event rates/100 person years according to age at first RTx.

A total of 115 patients were included (57% men; mean age at first transplant 13.9±3.7 years).  Allograft loss rates were similar across ages 14.0 to 23.9 years.  No increase in allograft loss was observed during transition period (ages 18.0-19.9 years).  Hospitalizations for RTx rejection or biopsy were much lower after age 18.

Our findings do not support an increased risk of allograft loss after transition to adult care, although there is less hospital use for rejection or biopsy suggesting that differences exist in use of care before complete allograft loss after transition to adult care.
