Simultaneous Deceased Donor Liver and Kidney Transplantation in a Human Immunodeficiency Virus/Hepatitis C Virus -Coinfected Patient With Hemophilia in Japan: A Case Report

The authors describe the first case of simultaneous liver and kidney transplantation (SLK) in a human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patient with severe hemophilia in Japan, and it could be second case in the world. The patient was a 61-year-old Japanese man with HCV cirrhosis complicated with HIV coinfection through contaminated blood product for hemophilia B at age 1 year. The patient's liver disease was classified as Child-Pugh C, Model for End-Stage Liver Disease score 38. He had been on hemodialysis for 6 years, but HIV RNA and HCV RNA had been undetectable after appropriate antiviral therapies. In September 2019, the patient underwent successful deceased donor (DD) SLK. The donor was a man in his 60s deceased due to cerebral hemorrhage. Regular DD liver transplantation was performed using the piggyback technique with a full-sized liver graft. Cold ischemia time was 566 min, and the graft liver weighed 1154 g. The graft kidney was transplanted extraperitoneally in the right iliac fossa. The administration of clotting factor IX was discontinued on day 3. The immunosuppressive regimen was based on intravenous induction with 2 mg/kg of basiliximab and 1 g methylprednisolone and subsequent oral administration of mycophenolate mofetil and prednisolone, followed by low-dose tacrolimus after 1 week for kidney-sparing purpose. Steroid therapy was gradually discontinued at 3 months after SLK. The same pretransplantation antiretroviral therapy (ART; tenofovir and dolutegravir) was introduced after 3 days when the CD4 cell count was more than 300/μL and HIV RNA was within an undetectable range. The postoperative course was uneventful without infectious complication, and the patient was transferred to a referral hospital on day 90 and discharged home on day 111. Strategic surgical planning and meticulous pre- and post-transplant management of ART and clotting factors could lead to the success of SLK.
