Successful ABO-incompatible living donor liver transplant for acute liver failure secondary to Hodgkin's Lymphoma in a child.

We present a case of pediatric ALF, secondary to hepatic HL, who underwent a successful ABOi living donor liver transplant. We believe this is the first such case reported in academic literature. HL with liver involvement is extremely rare and is not considered an indication for transplantation. The 12-year-old, male patient presented with a viral illness prodrome, and parvovirus was detected in pre-transplant laboratory cultures. He received an ABOi living donor liver graft followed by a course of plasma exchange and rituximab after which standard immunosuppression was used. The HL was diagnosed on hepatic biopsy post-transplant. Subsequently, the patient commenced six cycles of R-CHOP chemotherapy. During chemotherapy, we stopped tacrolimus and mycophenolate mofetil. Immunosuppression was maintained with corticosteroids in-between cycles. The patient is alive and reports good quality of life 1-year post-transplant. The HL is in remission. During the post-operative period, the patient experienced four episodes of neutropenia, a bile leak, and gram-negative sepsis. One episode of acute rejection has been treated. Although we did not initially transplant the patient for ALF secondary to HL, its subsequent diagnosis and the patient's response to management raises many issues that warrant consideration. While the findings from a single case cannot be generalized, this could be a "proof of concept" for liver transplantation in hepatic HL. We hope it will facilitate discussions and potentially expand therapeutic options available to this very small group patients.

Minding the gap-Providing quality transplant care for South African children with acute liver failure.

Pediatric ALF is rare but life-threatening and may require urgent transplantation. In low and middle-income countries, access to transplantation is limited, deceased organ donation rates are low, and data on outcomes scarce. The Wits Donald Gordon Medical Centre, in Johannesburg, is one of only two centers in South Africa that perform pediatric liver transplant. We describe the etiology, clinical presentation, and outcomes of children undergoing liver transplant for ALF at our center over the past 14 years. We performed a retrospective chart review of all children undergoing liver transplantation for ALF from November 2005 to September 2019. Recipient data included demographics, clinical and biochemical characteristics pretransplant, post-operative complications, and survival. We conducted descriptive data analysis and used the Kaplan-Meier method for survival analysis. We performed 182 primary pediatric liver transplants. Of these, 27 (15%) were for ALF, mostly from acute hepatitis A infection (11/27;41%). Just over half of the grafts were from living donors (15/27;56%), and five grafts (5/27;19%) were ABO-incompatible. The most frequent post-transplant complications were biliary leaks (9/27;33%). There were two cases of hepatic artery thrombosis (2/27;7%), one of whom required re-transplantation. Unadjusted patient and graft survival at one and 3 years were the same, at 81% (95% CI 61%-92%) and 78% (95% CI 57%-89%), respectively. At WDGMC, our outcomes for children who undergo liver transplantation for ALF are excellent. We found workable solutions that effectively addressed our pervasive organ shortages without compromising patient outcomes.
