Abstract
Living donor liver transplantation (LDLT) is recognised as an alternative treatment modality to reduce waiting list mortality and expand the donor pool. Over recent decades, there have been an increasing number of reports on the use of LT and specifically LDLT for familial hereditary liver diseases. There are marginal indications and contraindications that should be considered for a living donor in paediatric parental LDLT. No mortality or morbidity related to recurrence of metabolic diseases has been observed with heterozygous donors, except for certain relevant cases, such as ornithine transcarbamylase deficiency, protein C deficiency, hypercholesterolemia, protoporphyria, and Alagille syndrome, while donor human leukocyte antigen homozygosity also poses a risk. It is not always essential to perform preoperative genetic assays for possible heterozygous carriers; however, genetic and enzymatic assays must hereafter be included in the parental donor selection criteria in the aforementioned circumstances.

Long-term results of liver transplantation for maple syrup urine disease: A single-center experience in Turkey. Pediatr Transplant 2023; 27:e14464.

Abstract
OBJECTIVES Maple syrup urine disease (MSUD) is an autosomal recessive inherited disorder. Despite the advances in medical nutrition therapies, classical phenotype causes severe neurological disorders and sudden death. It is known that MSUD patients do not experience metabolic attacks despite their free diet after liver transplantation (LT). This study aims to reveal the long-term results, development, mental, motor, intellectual and nutritional status of MSUD patients who underwent LT. METHODS The data of 12 patients who underwent deceased donor (5 recipients) and living donor liver transplantation (7 recipients) were retrospectively analyzed. The age, genotype, psychometric and mental status, development, BCAA values, type of LT, donor-recipient proximity, complications, and survival were assessed. RESULTS There were 4 (33%) girls and 8 (67%) boys. The mean current age was 9.33 ± 4.58 years. The mean follow-up time was 3 ± 2.5 years. The repeated measures of leucine and isoleucine values revealed that there were no significant differences from the pre-LT to post-LT 1-year. The protein-restricted nutrition was switched to a free diet when oral intake was opened after LT. None of the recipients experienced metabolic attacks after the living donor or deceased donor LT. The 1-, 3-, and 5-year survival rate of the patients is 83.3%. There was no significant difference in survival between living and deceased donor liver transplantation. CONCLUSIONS Liver transplantation is a treatment option for MSUD in proper conditions to save the patient life, increase the quality of life, and provide essential amino acids with free diet intake for growth and development.

Hyperleucinosis during infections in maple syrup urine disease post liver transplantation. Mol Genet Metab Rep 2021; 27:100763. [PMID: 33996492 PMCID: PMC8102797 DOI: 10.1016/j.ymgmr.2021.100763] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/19/2021] [Accepted: 04/19/2021] [Indexed: 11/29/2022] Open
Abstract
Maple syrup urine disease (MSUD) is due to biallelic variants in one of the three genes: BCKDHA, BCKDHB, and DBT. Branched-chain alpha-ketoacid dehydrogenase complex deficiency and elevated leucine, valine, isoleucine and alloisoleucine in body fluids are the results. We report hyperleucinosis during intercurrent illnesses in six patients with MSUD post liver transplantation. Patient charts were retrospectively reviewed. Data was entered into an Excel Database. Literature was reviewed. Six patients with MSUD were included who had post liver transplantation hyperleucinosis during an intercurrent illness. Five had encephalopathy. One received hemodialysis for the management of hyperleucinosis. All patients had unrestricted diet. Additionally, there were five patients (one patient included into the current study) reported in the literature. We suggested management considerations for the follow-up of patients with MSUD post liver transplantation after the first episode of unexplained encephalopathy or signs of acute hyperleucinosis during intercurrent illness due to our clinical experience: 1) Healthy: Unrestricted diet and monitoring of leucine levels; 2) Illness: a) home illness management: increased carbohydrate intake b) illness management at hospital: intravenous dextrose, intravenous lipid and daily plasma amino acid monitoring. We report hyperleucinosis and/or encephalopathy as a rare event post liver transplantation in MSUD as a multicenter case series. Hyperleucinosis and/or encephalopathy may occur in both related and unrelated donor liver transplantation. Based on the long-term follow-up of those patients, these suggested management considerations may be revised as per the patients' needs. Patients with MSUD can present with hyperleucinosis during intercurrent illness post liver transplantation. Hyperleucinosis in MSUD post liver transplantation can occur in related and unrelated donor liver transplantation. Monitoring of patients with MSUD is required after their first episode of hyperleucinosis post liver transplantation.

Abstract
Citrullinemia or ASS deficiency in its classical form presents in the neonatal period with poor feeding, hyperammonemia, encephalopathy, seizures, and if untreated can be fatal. Despite advances in medical therapy, neurocognitive outcomes remain suboptimal. LT has emerged as a potential management option. A retrospective single-center review identified 7 children with a median age of 1.1 years (range, 0.6-5.8) at referral. Five children presented clinically, and 2 were treated prospectively from birth due to positive family history. All patients received standard medical and dietary therapy prior to LT. The indications for LT were frequent metabolic decompensations in 4, elective in 2, and ALF in 1. The median age at LT was 2.4 years (range, 1.3-6.5). Five patients received 6 left lateral segment grafts, one a live unrelated donor left lateral segment as an APOLT graft, and one a cadaveric whole liver graft as APOLT. One child required retransplantation due to hepatic artery thrombosis. Graft and patient survival were 86% and 100%, respectively. Median follow-up is 3.1 years (range, 0.1-4.1), and the median age at follow-up is 5.5 years (range, 4.0-9.8). There have been no metabolic decompensations in 6 children, while 1 patient (with APOLT) developed asymptomatic hyperammonemia with no clinical or histological signs of liver injury, requiring additional medical therapy. Our medium-term experience following LT in citrullinemia is favorable, demonstrating a positive transformation of the clinical phenotype.

Abstract
Classical MSUD is often fatal without appropriate medical interventions because of metabolic crisis. There are numerous reports suggesting the therapeutic potential of deceased donor liver transplantation for MSUD. However, the usefulness of LDLT for MSUD is unknown. We report a case of classical MSUD, which was successfully managed by LDLT from the patient's father at 1 year of age. Abnormal brain findings, which were cured with effective treatment, gradually disappeared after LDLT. The patient then developed normally. Findings from this case suggest the importance of LDLT for maintaining low leucine levels and subsequent normal neurological development. Although LDLT involves a modest surgical insult, LDLT with a related donor achieves acceptable leucine levels for life.
