Data were gathered from the records of 51 children of median age 1.5 years who survived more than 6 months after intestinal transplantation. Abnormal liver function tests (LFTs) were defined as serum aspartate aminotransferase (AST) greater than 100 IU/L or total bilirubin greater than 2.0 g/dL lasting more than 3 days. Temporary elevation was defined when LFTs returned to normal without graft loss or death. LFT elevation at the time of transplantation was not included as a temporary LFT elevation. Median follow-up was 36 months. In multivisceral transplant recipients, all patients (n = 34) showed abnormal LFTs at transplantation that normalized within a median period of 2 days. Temporary LFT elevations were seen in 20 of 34 (59%) in multivisceral transplantation and 5 of 17 (29%) in isolated intestinal transplantation. Median length of elevation was 14 days in multivisceral transplantation and 12 days in isolated intestinal transplantation. Peak AST was 353 ± 190 IU/dL in multivisceral transplantation and 839 ± 605 IU/dL in isolated intestinal transplantation (P = .0059). Events associated with temporary LFT elevations in multivisceral transplantation were total parental nutrition (TPN) (n = 8), dehydration (n = 2), viral infection (n = 2), others (n = 3), and nonspecific (n = 5). Events in isolated intestinal transplantation were posttransplant lymphoproliferative disorder (n = 2), TPN (n = 1), and nonspecific (n = 2). Temporary LFT elevations were commonly seen among pediatric intestinal recipients, which correlated with events other than rejection. Approximately half of the temporary LFT elevations were associated with no significant clinical events. They resolved spontaneously. Interestingly, the peak AST value was higher in isolated intestinal transplantation compared to multivisceral transplantation.
