Abstract
Orthotopic liver transplantation (OLT) in the care of children with inborn errors of metabolism (IEM) is well established and represent the second most common indication for pediatric liver transplantation in most centers worldwide, behind biliary atresia. OLT offers cure of disease when a metabolic defect is confined to the liver, but may still be transformative on a patient's quality of life reducing the chance of metabolic crises causing neurological damage in children be with extrahepatic involvement and no "functional cure." Outcomes post-OLT for inborn errors of metabolism are generally excellent. However, this benefit must be balanced with consideration of a composite risk of morbidity, and commitment to a lifetime of post-transplant chronic disease management. An increasing number of transplant referrals for children with IEM has contributed to strain on graft access in many parts of the world. Pragmatic evaluation of IEM referrals is essential, particularly pertinent in cases where progression of extra-hepatic disease is anticipated, with long-term outcome expected to be poor. Decision to proceed with liver transplantation is highly individualized based on the child's dynamic risk-benefit profile, their family unit, and their treating multidisciplinary team. Also to be considered is the chance of future treatments, such as gene therapies, emerging in the medium term.

Abstract
Metabolic liver diseases (MLD) are the second most common indication for liver transplantation (LT) in children. This is based on the fact that the majority of enzymes involved in various metabolic pathways are present within the liver and LT can cure or at least control the disease manifestation. LT is also performed in metabolic disorders for end-stage liver disease, its sequelae including hepatocellular cancer. It is also performed for preventing metabolic crisis’, arresting progression of neurological dysfunction with a potential to reverse symptoms in some cases and for preventing damage to end organs like kidneys as in the case of primary hyperoxalosis and methyl malonic acidemia. Pathological findings in explant liver with patients with metabolic disease include unremarkable liver to steatosis, cholestasis, inflammation, variable amount of fibrosis, and cirrhosis. The outcome of LT in metabolic disorders is excellent except for patients with mitochondrial disorders where significant extrahepatic involvement leads to poor outcomes and hence considered a contraindication for LT. A major advantage of LT is that in the post-operative period most patients can discontinue the special formula which they were having prior to the transplant and this increases their well-being and improves growth parameters. Auxiliary partial orthotopic LT has been described for patients with noncirrhotic MLD where a segmental graft is implanted in an orthotopic position after partial resection of the native liver. The retained native liver can be the potential target for future gene therapy when it becomes a clinical reality.

Abstract
After half a century of development, auxiliary liver transplantation (ALT) technology gradually matured and major indications of ALT have been gradually expanded. This review summarized the history of ALT and introduced indications for ALT which including metabolic liver disease, fulminant hepatic failure, highly sensitized kidney transplantation, prevention of hepatic resection of small hepatic syndrome, etc.; at the same time, the hot issues related to ALT were discussed, including the regulation of hepatic portal blood flow of transplanted liver and residual liver, how to treat the graft liver and remaining liver on second stage. Additionally, the expansion of indications for ALT which included the implementation of ALT for patients with liver cancer and ALT for patients with liver cirrhosis was discussed. It was believed that ALT can greatly alleviate the contradiction of insufficient source of graft liver.

Abstract
PURPOSE To investigate the efficacy of living donor liver transplantation (LDLT) plus domino-auxiliary partial orthotopic liver transplantation (D-APOLT) in pediatric patients with metabolic disorders. METHODS From May 2017 to October 2018, two patients with ornithine aminotransferase deficiency (OTCD) and one patient with type I Crigler-Najjar syndrome (CNS1) received LDLT, their livers were prepared as donors for D-APOLT. Two patients with CNS1 received domino liver grafts from OTCD patients; one OTCD patient received a domino liver graft from a CNS1 patient. RESULTS The mean follow-up was 26.6 months. The liver function and ammonia remained in the normal range at the end of the follow-up in all recipients. One D-APOLT patient experienced portal vein thrombosis 2 days after transplantation and required reoperation, this patient presented an imbalance of portal blood perfusion between the native and the domino liver at 8 months after liver transplant. The imbalance was improved by interventional radiology treatment. Two LDLT patients experienced early mild acute rejection. CONCLUSIONS The non-cirrhotic livers from pediatric patients with metabolic liver disease can be used as domino donor grafts for selected pediatric patients with different metabolic liver disease. D-APOLT achieves ideal recipient outcomes and provides a strategy to expand donor source for children.

Abstract
Although orthotopic liver transplantation remains the only proven treatment for end-stage liver disease and inherited metabolic liver disease, its application has been limited by the scarcity of donor organs available for transplantation. Among feasible approaches developed to expand the donor organ pool, domino liver transplantation is a strategy in which explanted genetically defective livers of liver transplant recipients are used as grafts in other patients. Another promising therapeutic strategy is hepatocyte transplantation, an alternative to liver transplantation for certain groups of patients. However, the availability of primary hepatocytes is also hindered by the shortage of donor liver tissues. Against this background, domino hepatocyte transplantation, a strategy that utilizes the hepatocytes derived from the explanted livers of liver transplant recipients with noncirrhotic inherited metabolic liver diseases as the source of primary hepatocytes, may help increase the supply of liver cells available for transplantation. In this review, we focus on the status quo of domino liver transplantation and domino hepatocyte transplantation. We also describe recent innovative transplant strategies based on domino transplantation.

Abstract
BACKGROUND Domino transplant occurs when a recipient explanted graft is used for a second recipient. INTRODUCTION The first experience came from thoracic surgery by the observation that many patients during heart-lung transplantation actually showed a functional heart that could be employed in other subjects with a good result. RESULTS This concept was then extended to the field of liver transplantation. At present, some patients transplanted for an inborn metabolic disease may be considered as excellent domino liver donors. CONCLUSION The results, limitations, clinical challenges and the donor and recipient features of domino liver transplantation are discussed in this manuscript.

Abstract
AIM/BACKGROUND Domino liver transplantation (DLT) using liver allografts from patients with metabolic disorders enhances organ utilization. Short- and long-term course and outcome of these patients can impact the decision to offer this procedure to patients, especially those with diseases that can potentially be cured with liver transplant. We reviewed the outcomes of DLT from maple syrup urine disease (MSUD) patients in our large academic pediatric and adult transplant program. METHODS All patients receiving DLT were analyzed retrospectively with a minimum of one-year follow-up period for patient and donor characteristics, early and late postoperative complications and patient and graft survival with their MSUD donors in terms of age, weight, MELD/PELD scores, cold ischemia time, postoperative leucine levels, and peak ALT (alanine aminotransferase) levels during the first 48 postoperative hours. RESULTS Between 2006 and May 2019, 21 patients underwent domino liver transplantation with live donor allografts from MSUD patients. Four patients transplanted for different metabolic diseases are focus of a separate report. Seventeen patients with minimum one-year follow-up period are reported herein. The indications were primary sclerosing cholangitis (PSC, n = 4), congenital hepatic fibrosis (CHF, n = 2), alpha-1 antitrypsin deficiency (A-1 ATD, n = 2), progressive familial intrahepatic cholestasis (PFIC, n = 2), cystic fibrosis (n = 1), primary biliary cirrhosis (PBC, n = 1), neonatal hepatitis (n = 1), embryonal sarcoma (n = 1), Caroli disease (n = 1), hepatocellular carcinoma (HCC, n = 1), and chronic rejection after liver transplantations for PSC (n = 1). All patients and grafts survived at median follow-up of 6.4 years (range 1.2-12.9 years). Median domino recipient age was 16.2 years (range 0.6-64.6 years) and median MSUD recipient age was 17.6 years (range 4.8-32.1 years). There were no vascular complications during the early postoperative period, one patient had portal vein thrombosis 3 years after DLT and a meso-Rex bypass was successfully performed. Small for size syndrome (SFSS) occurred in reduced left lobe DLT recipient and was managed successfully with conservative management. Biliary stricture developed in 2 patients and was resolved by stenting. Comparison between DLT and MSUD recipients' peak postoperative ALT results and PELD/MELD scores showed lower levels in DLT group (P-value <.05). CONCLUSIONS Patient and graft survival in DLT from MSUD donors was excellent at short- and long-term follow-up. Metabolic functions have been normal in all recipients on a normal unrestricted protein diet. Ischemia preservation injury based on peak ALT was significantly decreased in DLT recipients. Domino transplantation from pediatric and adult recipients with selected metabolic diseases should be increasingly considered as an excellent option and alternative to deceased donor transplantation, thereby expanding the living donor pool. This, to date, is the largest world experience in DLT utilizing livers from patients with MSUD.

Abstract
Domino liver transplantation (DLT) involves transplanting liver from a patient with metabolic disease into a patient with end-stage liver disease with the expectation that the recipient will not develop the metabolic syndrome or the recurrent syndrome will have minimal affect. The domino donor gets a deceased donor or a segment of live-donor liver through the deceased donor organ allocation system. Waitlist mortality for the domino recipient exceeds morbidity associated with getting the donor disease. Between 2015 and 2017, four patients with three metabolic disorders at UPMC Children's Hospital of Pittsburgh underwent DLT with domino allografts from maple syrup urine disease (MSUD) patients. These included patients with propionic acidemia (PA) (n = 1), Crigler-Najjar (CN) syndrome type-1 (n = 2), and carbamoyl phosphate synthetase deficiency (CPSD) (n = 1). Mean follow-up was 1.6 years (range 1.1-2.1 years). Total bilirubin levels normalized postoperatively in both CN patients and they maintain normal allograft function. The PA patient had normal to minimal elevations of isoleucine and leucine, and no other abnormalities on low protein diet supplemented with a low methionine and valine free formula. No metabolic crises have occurred. The patient with CPSD takes normal baby food. No elevation in ammonia levels have been observed in any of the patients. DLT for a select group of metabolic diseases alleviated the recipients of their metabolic defect with minimal evidence of transferrable-branched chain amino acid elevations or clinical MSUD despite increased protein intake. DLT using allografts with MSUD expands the live donor liver pool and should be considered for select metabolic diseases that may have a different enzymatic deficiency.

Abstract
Indications for liver transplantation (LT) in metabolic disease are evolving. We reviewed the US experience with primary LT for metabolic disease in the Scientific Registry for Transplant Recipients (October 1987 to June 2017) to determine the following: temporal changes in indications, longterm outcomes, and factors predicting survival. Patients were grouped by the presence of structural liver disease (SLD) and whether the defect was confined to the liver. There were 5996 patients who underwent LT for metabolic disease, 2354 (39.3%) being children. LT for metabolic disease increased in children but not in adults. Children experienced a 6-fold increase in LT for metabolic disease without SLD. Indications for LT remained stable in adults. Living donor liver transplantation increased between era 1 and era 3 from 5.6% to 7.6% in children and 0% to 4.5% in adults. Patient and graft survival improved with time. The latest 5-year patient survival rates were 94.5% and 81.5% in children and adults, respectively. Outcomes were worse in adults and in those with extrahepatic disease (P < 0.01), whereas SLD did not affect outcomes. Survival improved with younger age at LT until age <2 years. On multivariate analysis, diagnostic category, inpatient status, age at LT, and transplant era significantly predicted outcomes in all ages with male sex predicting survival in childhood only. Children without structural disease were less likely to die awaiting LT and had improved post-LT survival compared with children with chronic liver disease. In conclusion, LT for metabolic disease is increasingly used for phenotypic correction in children; extrahepatic manifestations significantly impact survival at all ages; where indicated, transplantation should not be unnecessarily delayed; and the development of new allocation models may be required.

Abstract
PURPOSE Auxiliary partial orthotopic liver transplantation (APOLT) in metabolic liver disease (MLD) has the advantage of correcting the metabolic defect, preserving the native liver for gene therapy in the future with the possibility of withdrawal of immunosuppression. METHODS Retrospective analysis of safety and efficacy of APOLT in correcting the underlying defect and its impact on neurological status of children with MLD. RESULTS A total of 13 APOLT procedures were performed for MLD during the study period. The underlying aetiologies being propionic acidemia (PA)-5, citrullinemia type 1 (CIT1)-3 and Crigler-Najjar syndrome type 1 (CN1)-5 cases respectively. Children with PA and CIT1 had a median of 8 and 4 episodes of decompensation per year, respectively, before APOLT and had a mean social developmental quotient (DQ) of 49 (<3 standard deviations) as assessed by Vineland Social Maturity Scale prior to liver transplantation. No metabolic decompensation occurred in patients with PA and CIT1 intraoperatively or in the immediate post-transplant period on protein-unrestricted diet. Patients with CN1 were receiving an average 8-15 h of phototherapy per day before APOLT and had normal bilirubin levels without phototherapy on follow-up. We have 100% graft and patient survival at a median follow-up of 32 months. Progressive improvement in neurodevelopment was seen in children within 6 months of therapy with a median social DQ of 90. CONCLUSIONS APOLT is a safe procedure, which provides good metabolic control and improves the neurodevelopment in children with selected MLD.

Abstract
Domino liver transplant has emerged as a viable strategy to increase the number of grafts available for transplantation. In the domino transplant organs explanted from one patient are transplanted into another patient. The first successful domino liver transplant was performed in Portugal in 1995. Since then this innovative concept has been applied to several genetic or biochemical disorders that are treated by liver transplantation. An important consideration during this operation is that such livers can pose a risk of the de novo development of the disease in the recipient. That is why this surgical procedure requires careful planning, proper selection of the patients, and informed consent of both donor and recipient.

Abstract
Even though auxiliary partial orthotopic liver transplantation (APOLT) as a technique was popularized in the late 80s, its role in metabolic liver disease remains controversial. The slow progress in gene therapy research, high incidence of technical complications, and the problem of long term graft atrophy have been roadblocks to its wider application. Better understanding of reciprocal dynamics of portal flow and regeneration between the graft and native liver along with multiple refinements in surgical technique have improved the outcomes of this operation, making it a safe alternative to orthotopic liver transplantation for patients with a wide range of noncirrhotic metabolic liver diseases (NCMLD). The ability to perform APOLT safely has also opened up a range of exciting indications in the setting of NCMLD. This article reviews the current status of APOLT for NCMLD, technical refinements which have improved outcomes and novel indications, which have rekindled fresh interest in this procedure.

Abstract
Liver transplantation as an established form of treatment for end-stage liver disease has gained acceptance in India over the last 10 years. Liver transplantation in India has unique features that have contributed to the growth of both deceased donor and living donor transplantations of which living donor currently dominates the picture. Living donor contributes to 80% and deceased donor to 20% of the liver transplants currently performed in India. The majority of these transplants are performed within the private sector with public sector hospitals lagging behind significantly. This article gives an overview of the evolution of liver transplantation in India and the potential future challenges. Liver Transplantation 22 1019-1024 2016 AASLD.

Abstract
Liver transplantation is currently in its golden period in India. The number of transplants being performed and the steady increase in the new programs that have emerged over the last decade is a testimony to it. The growth was not smooth, especially in the early years. But a multipronged approach in developing infrastructure and the involvement of multidisciplinary teams in the management of transplant patients has had a major positive impact on the outcome and as a result a positive impetus to the growth of this specialty in India. To date, the majority of transplants performed in India are live donor liver transplants. Deceased donation is more sporadic and concentrated in a couple of regions. With phenomenal increase in transplant activity in India, there is huge potential for streamlining data sharing among programs in India and with the rest of the world to ultimately benefit the transplant community.
