%X In cases of acute liver failure (ALF) with hepatic coma, early liver transplantation, including ABO-incompatible (ABOi) living donor liver transplantation (LDLT), should be considered. The ABO antibody barrier can be reduced using plasma exchange (PE) and the anti-CD20 antibody rituximab. Plasma exchange is also performed for drug-induced ALF and is effective for desensitization. Rituximab treatment usually requires 14 days. There is presently no established desensitization protocol for ABOi-LDLT for ALF. Here, we report a case of drug-induced ALF with hepatic coma, which was treated with ABOi-LDLT using PE and rituximab 8 days prior to surgery. A 33-year-old female, with a history of headaches for which she was taking analgesics daily, developed drug-induced ALF with hepatic coma. Her ABOi sister desired to become a liver donor. We initiated desensitization using rituximab (500 mg) and mycophenolate mofetil (MMF, 2000 mg/day), followed by five sessions of PE. Eight days after rituximab administration, ABOi-LDLT with splenectomy was performed. Postoperatively, the patient received local infusion via portal vein for 14 days and immunosuppression with tacrolimus, methylprednisolone, and MMF. No episode of cellular or antibody-mediated rejection (AMR) was observed. The patient was discharged uneventfully 56 days after ABOi-LDLT with no problems up to 15 months after the transplant.
