Abstract
Backgrounds/AimsGraft survival after ABO-incompatible (ABOi) living donor liver transplantation (LDLT) has increased due to advances in desensitization methods. We analyzed early outcomes following ABOi LDLT using only rituximab without any additional desensitization methods in recipients with low anti-ABO antibody titers (≤1:32).MethodsTen adult patients underwent ABOi LDLT between September 2014 and December 2016. All patients were administered a single dose of rituximab (300 mg/m2) prior to LDLT. Three patients with baseline anti-ABO titer >1:32 underwent multiple sessions of plasmapheresis to reduce titers to <1:32 (rituximab+plasmapheresis, RP). Seven patients with low anti-ABO titer (≤1:32) did not undergo plasmapheresis (rituximab-only, RO). ABO-compatible LDLT patients during the same period were included for comparison (n=22).ResultsPost-transplantation titers were significantly lower in the RO than in the RP and showed no rebound rise (POD7 1.14±0.38 vs 28.0±31.7, p=0.04), (POD30 1.26±0.45 vs 108±107, p=0.02). There were no significant differences in rejection, biliary complications and infection between groups. There were no significant differences in outcome between the RO group and ABO-compatible except for infection.ConclusionsThis study shows that recipients with low baseline anti-ABO antibody titer (≤1:32) can undergo ABOi LDLT using conventional immunosuppression and rituximab alone.
