Aim: To assess the preoperative disease characteristics and indications for living donor liver transplantation (LDLT), complications, patient survival, and prognosis after LDLT for fibropolycystic liver disease (FLD) in children.

Methods: We undertook a cross-sectional survey of patients who underwent LDLT for FLD between January 2002 and December 2020.

Results: A total of 35 patients (22 male and 13 female individuals) with FLD were included in this study, of whom 19 (54.

Optimal timing of liver transplantation for liver cirrhosis caused by sclerosing cholangitis in a patient with Langerhans cell histiocytosis: a case report.

Liver cirrhosis due to secondary sclerosing cholangitis caused by Langerhans cell histiocytosis (LCH) has a poor prognosis, and liver transplantation is the definitive treatment. However, the optimal timing has not been established. We report a 2-year-old girl with LCH-related liver cirrhosis who successfully underwent liver transplantation before progressing to severe liver dysfunction.

Feasibility of Real-Time Central Surgical Review for Patients with Advanced-Stage Hepatoblastoma in the JPLT3 Trial.

In the JPLT3 study, a real-time central surgical reviewing (CSR) system was employed aimed at facilitating early referral of candidates for liver transplantation (LTx) to centers with pediatric LTx services. The expected consequence was surgery, including LTx, conducted at the appropriate time in all cases. This study aimed to review the effect of CSR on institutional surgical decisions in cases enrolled in the JPLT3 study.

Successful living donor liver transplantation for liver failure due to maternal T cell engraftment following cord blood transplantation in X-linked severe combined immunodeficiency disease: Case report.

Maternal T cells from perinatal transplacental passage have been identified in up to 40% of patients with severe combined immunodeficiency (SCID). Although engrafted maternal T cells sometimes injure newborn tissue, liver failure due to maternal T cells has not been reported. We rescued a boy with X-linked SCID who developed liver failure due to engrafted maternal T cell invasion following living donor liver transplantation (LDLT) following unrelated umbilical cord blood transplantation (UCBT).

Hospitalisations due to respiratory syncytial virus infection in children with Down syndrome before and after palivizumab recommendation in Japan.

Aim: Down syndrome has been considered an independent risk factor for respiratory syncytial virus (RSV) infection. Palivizumab, an anti-RSV humanised monoclonal antibody, was currently approved for all children with Down syndrome in Japan. To investigate the change in RSV-associated hospitalisation (RSVH) rates before and after the universal approval of palivizumab in Japan in 2013, we conducted a nationwide retrospective survey.

Ferroptosis driven by radical oxidation of n-6 polyunsaturated fatty acids mediates acetaminophen-induced acute liver failure.

Acetaminophen (APAP) overdose is a common cause of drug-induced acute liver failure. Although hepatocyte cell death is considered to be the critical event in APAP-induced hepatotoxicity, the underlying mechanism remains unclear. Ferroptosis is a newly discovered type of cell death that is caused by a loss of cellular redox homeostasis.

Iron overload as a risk factor for hepatic ischemia-reperfusion injury in liver transplantation: Potential role of ferroptosis.

Hepatic ischemia-reperfusion (I/R) injury is a major problem in liver transplantation (LT). Although hepatocyte cell death is the initial event in hepatic I/R injury, the underlying mechanism remains unclear. In the present study, we retrospectively analyzed the clinical data of 202 pediatric living donor LT and found that a high serum ferritin level, a marker of iron overload, of the donor is an independent risk factor for liver damage after LT.

A Multicenter Japanese Survey Assessing the Long-term Outcomes of Liver Retransplantation Using Living Donor Grafts.

Background: Liver transplantation is the most suitable treatment option available for end-stage liver disease. However, some patients require retransplantation, despite medical advances that have led to improved survival. We aimed to compile a definitive, nationwide resource of liver retransplantation data in Japan, seeking to identify the predictors of patient survival posttransplantation.

Endovascular stent placement for venous complications following pediatric liver transplantation: outcomes and indications.

Purpose: Advances in interventional radiology (IVR) treatment have notably improved the prognosis of hepatic vein (HV) and portal vein (PV) complications following pediatric living donor liver transplantation (LDLT); however, graft failure may develop in refractory cases. Although endovascular stent placement is considered for recurrent stenosis, its indications are controversial.

Methods: We enrolled 282 patients who underwent pediatric LDLT in our department from May 2001 to September 2016.

Pediatric liver transplantation for neonatal-onset Niemann-Pick disease type C: Japanese multicenter experience.

Niemann-Pick disease type C (NPC) is a rare autosomal recessive inherited disease characterized by lysosomal accumulation of free cholesterol in macrophages within multiple organs. Infantile-onset NPC often presents with jaundice and hepatosplenomegaly from birth, but these symptoms usually improve during early childhood, and it rarely progresses to liver failure. We report three cases from different hospitals in Japan; the patients developed neonatal-onset NPC, and liver transplantation (LT) was performed as a life-saving procedure.

Long-term outcome of percutaneous transhepatic biliary drainage for biliary strictures following pediatric liver transplantation.

Background: We present a retrospective analysis of our experience with pediatric liver transplantation (LT), focusing on the long-term outcome of percutaneous transhepatic biliary drainage (PTBD) for post-transplant biliary strictures.

Methods: Fifty-three PTBDs were performed for 41 pediatric recipients with biliary strictures. The median ages at LT and PTBD were 1.

Biliary Complications Following Pediatric Living Donor Liver Transplantation: Risk Factors, Treatments, and Prognosis.

Background: We present retrospective analysis of our 15-year experience with pediatric living donor liver transplantation, focusing on the risk factors, treatments, and long-term prognosis for posttransplant biliary complications (BCs).

Methods: Between May 2001 and December 2017, 290 living donor liver transplantations were performed. The median age was 1.

Visceral artery anomalies in patients with Alagille syndrome.

Background: Intracranial and pulmonary vascular anomalies are well-known complications and causes of mortality in AGS; however, visceral artery anomalies are less commonly recognized. Herein, we present a retrospective analysis of our experience with pediatric LDLT that focuses on the current problems with and treatments for visceral artery anomalies in AGS after LDLT.

Methods: Between May 2001 and December 2017, 294 LDLTs were performed for 285 pediatric recipients.

Increased tacrolimus blood concentration by Beni-Madonna - a new hybrid citrus cultivar categorized as 'Tangor', in a liver transplant patient: likely furanocoumarin-mediated inhibition of CYP3A4 or P-glycoprotein.

Adverse Event: A drug interaction leading to greater exposure to tacrolimus.

Drug Implicated: Tacrolimus and Beni-Madonna (a new cultivar citrus categorized as 'Tangor').

The Patient: A 9-month-old girl with biliary atresia (body weight, 7.

Congenital absence of the portal vein: translated version.

Congenital portosystemic shunt (CPS) is classified into type I (congenital absence of the portal vein) and type II, depending on the presence or absence of the intrahepatic portal vein. Reports still exist on cases in which psychiatric diseases or mental retardation was diagnosed or cases in which diagnosis and treatment are not performed until severe pulmonary complications occur, indicating the need to recognize CPS. Herein, we reviewed epidemiology, etiology, classification, symptom, diagnosis, and treatment based on clinical view points of CPS.

Serum Mac-2 binding protein glycosylation isomer predicts the activation of hepatic stellate cells after liver transplantation.

Background And Aim: Serum Mac-2 binding protein glycosylation isomer (M2BPGi) is a novel fibrosis marker for various chronic liver diseases. We investigated the ability of M2BPGi to predict liver fibrosis in liver transplant (LT) recipients.

Methods: A total of 116 liver biopsies were performed in 113 LT recipients.

The Japanese experience and pharmacokinetics of antenatal maternal high-dose immunoglobulin treatment as a prophylaxis for neonatal hemochromatosis in siblings.

Neonatal hemochromatosis (NH) is a rare but serious disease causing fulminant hepatic failure. The recurrence rate of NH in a subsequent infant of a mother with an affected infant is 70-90%. Recently, antenatal maternal high-dose intravenous immunoglobulin (IVIG) treatment has been reported to be effective for preventing NH recurrence.
