| Abstract: | There is currently no way to diagnose a rejection before a change in serum creatinine. This had led some to start doing SB, but little data exist on the utility and safety of SB in pediatric patients. There is also little known on practice patterns of pediatric nephrologists. A retrospective review of pediatric kidney transplant SB between January 2013 and January 2017 at a single center was performed. A survey went to the PedNeph email list. There were 47 SB; 15 at 6 months, 12 at 1 year, 13 at 2 years, and 7 at 3 years. There were 3 minor (1 gross hematuria and 2 hematomas) and no major complications. On 6‐month SB, 1 had SC 1A ACR (6.7%) with no BR ACR. On the 12‐month SB, there were 5 with SCBR ACR (41.7%) and 1 with SC AMR (8.3%). On the 2‐year SB, there were 4 that had SCBR ACR (30.8%), and 1 with SC AMR (7.7%). On the 3‐year SB, 1 had chronic transplant glomerulitis (14.3%). The survey showed that 34.3% of pediatric nephrologists perform SB. SB can be performed safely. By early identification of histological lesions, SB gives us an opportunity for individualized immunosuppressive regimens that may prevent chronic allograft dysfunction and improve long‐term graft outcome. |
