Abstract
Alagille syndrome causes intractable pruritus and disfiguring xanthomas because of retained bile acids and cholesterol. Drug therapy in addition to surgical intervention may be effective in many patients in reducing serum bile acids, cholesterol levels, pruritus, and skin xanthomas. In this report, we describe a child with Alagille syndrome who presented with severe pruritus and xanthomas as a consequence of severe hypercholesterolemia and discuss the treatment modalities.

Abstract
AMR is a risk factor for graft failure after SBTx. We studied impact of DSAs and AMR in 22 children transplanted between 2008 and 2012 (11 isolated SBTx, 10 liver inclusive Tx, and one modified multivisceral Tx). Three patients never developed DSA, but DSAs were found in seven in the pre-Tx period and de novo post-Tx in 19 children. Pathology revealed cellular rejection (15/19), with vascular changes and C4d+. Patients were treated with IV immunoglobulins, plasmapheresis, and steroids. Rescue therapy included antithymocyte globulins, rituximab, eculizumab, and bortezomib. Pathology and graft function normalized in 13 patients, graft loss occurred in two, and death in seven. At the end of the follow-up, 15 children were alive (68%), 13 with functioning graft (59%). Prognosis factors for poor outcome after Tx were the presence of symptoms at AMR suspicion (P +.033). DSAs were often found following SBTx, mostly de novo. Resistant ACR or severe AMR is still difficult to differentiate, with a high need for immunosuppression in both. DSAs may precede development of severe disease and pathology features on the graft: relationship and correlation need to be better investigated with larger groups before and after Tx.

Abstract
Chronic hepatitis B virus (HBV) infection leads to a risk of developing cirrhosis and hepatocellular carcinoma. In France, where the prevalence of HBV is low, mother-to-child transmission is the cause of chronic infection in more than one-third of cases. After exposure, the risk of chronic infection is the highest for newborns (90 %). The World Health Organization implemented a global immunization program in 1991, applied in France in 1994. A significant number of children are infected each year, however, and failure of postexposure prophylaxis is reported in 4-10 % of newborns. We report 11 children with chronic HBV infection due to failure of serovaccination, followed up in two centers between 1993 and 2015. We discuss maternal screening, serovaccination, and follow-up conditions, as well as the role of maternal viral load, amniocentesis, and mode of delivery as risk factors. These observations confirm that serovaccination failures are related to the nonobservance of recommendations for maternal screening or postexposure prophylaxis, and to a high maternal viral load (>106 copies/mL). We therefore recommend improving the screening strategy, with control of the hepatitis B antigen in early pregnancy, and discussion of treatment with a nucleoside analog during the last trimester of pregnancy. Serovaccination should be enforced. Its efficacy should be controlled when the child reaches 9 months of age, in order to organize the follow-up if infection occurs.

Abstract
This study analyzes the preoperative risk factors for intra-operative bleeding in our recent series of pediatric LTs. Between November 2009 and November 2014, 84 consecutive isolated pediatric LTs were performed in 81 children. Potential preoperative predictive factors for bleeding, amount of intra-operative transfusions, postoperative course, and outcome were recorded. Cutoff point for intra-operative HBL was defined as intra-operative RBC transfusions ≥1 TBV. Twenty-six patients (31%) had intra-operative HBL. One-year patient survival after LT was 66.7% (CI 95%=[50.2-88.5]) in HBL patients and 83.8% (CI 95%=[74.6-94.1]) in the others (P=.054). Among 13 potential preoperative risk factors, three of them were identified as independent predictors of high intra-operative bleeding: abdominal surgical procedure(s) prior to LT, factor V level ≤30% before transplantation, and ex situ parenchymal transsection of the liver graft. Based on these findings, we propose a simple score to predict the individual hemorrhagic risk related to each patient and graft association. This score may help to better anticipate intra-operative bleeding and improve patient's management.

Abstract
BACKGROUND Parenteral nutrition (PN) is the main treatment for intestinal failure. OBJECTIVE We aimed to review the indications for home parenteral nutrition (HPN) in children and describe the outcome over a 14-y period from a single center. DESIGN We conducted a retrospective study that included all children who were referred to our institution and discharged while receiving HPN between 1 January 2000 and 31 December 2013. The indications for HPN were divided into primary digestive diseases (PDDs) and primary nondigestive diseases (PNDDs). We compared our results to a previous study that was performed in our unit from 1980 to 2000 and included 302 patients. RESULTS A total of 251 patients were included: 217 (86%) had a PDD. The mean ± SD age at HPN onset was 0.7 ± 0.3 y, with a mean duration of 1.9 ± 0.4 y. The indications for HPN were short bowel syndrome (SBS) (59%), PNDD (14%), congenital enteropathies (10%), chronic intestinal pseudo-obstruction syndromes (9%), inflammatory bowel diseases (5%), and other digestive diseases (3%). By 31 December 2013, 52% of children were weaned off of HPN, 9% of the PDD subgroup had intestinal transplantation, and 10% died mostly because of immune deficiency. The major complications of HPN were catheter-related bloodstream infections (CRBSIs) (1.7/1000 d of PN) and intestinal failure-associated liver disease (IFALD) (51 children; 20% of cohort). An increased rate of CRBSIs was observed compared with our previous study, but we saw a decreasing trend since 2012. No noteworthy deceleration of growth was observed in SBS children 6 mo after weaning off HPN. CONCLUSIONS SBS was the major indication for HPN in our cohort. IFALD and CRBSIs were potentially life-threatening problems. Nevertheless, complication rates were low, and deaths resulted mostly from the underlying disease.

Abstract
Vaccination is an effective strategy to decrease infections in transplant recipients. Children after intestinal transplantation carry a high risk of infection due to increased immunosuppression. In a series of 22 children after intestinal transplantation, we studied the vaccination schedules and the antibodies against vaccine-preventable diseases before transplantation, and at one and five yr after transplantation. We reviewed whether the vaccination schedules were complete, and we analysed the factors that may influence serological immunity and the incidence of disease in patients with deficient immunity. All patients completed the recommended vaccination schedules for DTaP-IPV and HBV. After transplantation, the negative antibodies against vaccine-preventable diseases were mostly related to an antirejection therapy: for DTaP-IPV: four of four patients with no antibody had been treated for rejection, for HBV: two of five, HAV: three of four, MMR: three of seven, and VZV: three of four. A post-transplantation varicella infection was followed by acute rejection, with probability for a relationship between both events. We observed 50% of varicella cases in unvaccinated children, highlighting the importance of pretransplant vaccination. Waning immunogenicity mediated by antibodies against vaccine-preventable disease after transplantation indicated a need for boosters. The recommendations should be regularly enforced, as the reliance on routine immunizations schedules is not adequate in immunocompromised patients.

Abstract
"Cholestasis" means abnormal synthesis or secretion of bile. The main symptom in a neonate or infant is jaundice. Urine is dark, staining diapers, and stools are variably pale or white. Vitamin K should be injected (to prevent coagulation disorders due to malabsorption). The two diagnoses requiring urgent treatment are urinary tract infection and biliary atresia. If stools are permanently white, biliary atresia is highly probable. A few genetic causes of intrahepatic cholestasis should be screened and corrective surgery organized. The diseases responsible for cholestasis in this age group are described as well as the investigations and treatments, including the management of non-specific complications of cholestasis. A delay in the diagnosis of biliary atresia can have such severe consequences that consultation with a hepatology unit or transfer should be easy and rapid.

Abstract
AIM To characterize the effect of donor and recipient CYP3A4, CYP3A5 and ABCB1 genotypes as well as relevant patient characteristics on tacrolimus pharmacokinetics in pediatric liver transplantation. PATIENTS & METHODS Data from 114 pediatric liver transplant recipients were retrospectively collected during the first 3 months following transplantation. Population pharmacokinetic analysis was performed using nonlinear mixed effects modeling, including characterization of influential covariates. RESULTS A two-compartment model with first order elimination best fitted the data. Estimates of apparent volume of the central compartment, intestinal clearance, hepatic clearance and intercompartmental clearance were 79 l, 0.01 l/h, 10.9 l/h and 105 l/h, respectively. Time post-transplantation, recipient age, donor CYP3A5 and CYP3A4 genotypes and fluconazole administration significantly influenced tacrolimus apparent clearance while bodyweight influenced volume of distribution. CONCLUSION The proposed model displayed acceptable fitting performances and enabled identification of statistically significant and clinically relevant covariates on tacrolimus pharmacokinetics in the early pediatric post liver transplantation period.

Abstract
Propionic acidemia (PA) is a severe metabolic disorder with cardiac and neurologic complications and a poor quality of life. Liver transplantation (LT) was thus proposed in PA to increase enzyme activity. We studied retrospectively LT in PA in two European centers. Twelve patients underwent 17 LTs between 1991 and 2013. They developed severe, unusual and unexpected complications, with high mortality (58%). When present, the cardiomyopathy resolved and no acute metabolic decompensation occurred allowing dietary relaxation. Renal failure was present in half of the patients before LT and worsened in all of them. We suggest that cardiac and renal functions should be assessed before LT and monitored closely afterward. A renal sparing immunosuppression should be used. We speculate that some complications may be related to accumulated toxicity of the disease and that earlier LT could prevent some of these consequences. As kidney transplantation has been performed successfully in methylmalonic acidemia, a metabolic disease in the same biochemical pathway, the choice of the organ to transplant could be further discussed.

Abstract
The Registry has gathered information on intestine transplantation (IT) since 1985. During this time, individual centers have reported progress but small case volumes potentially limit the generalizability of this information. The present study was undertaken to examine recent global IT activity. Activity was assessed with descriptive statistics, Kaplan-Meier survival curves and a multiple variable analysis. Eighty-two programs reported 2887 transplants in 2699 patients. Regional practices and outcomes are now similar worldwide. Current actuarial patient survival rates are 76%, 56% and 43% at 1, 5 and 10 years, respectively. Rates of graft loss beyond 1 year have not improved. Grafts that included a colon segment had better function. Waiting at home for IT, the use of induction immune-suppression therapy, inclusion of a liver component and maintenance therapy with rapamycin were associated with better graft survival. Outcomes of IT have modestly improved over the past decade. Case volumes have recently declined. Identifying the root reasons for late graft loss is difficult due to the low case volumes at most centers. The high participation rate in the Registry provides unique opportunities to study these issues.

Abstract
UNLABELLED Microvillous inclusion disease (MVID) is a congenital disorder of the enterocyte related to mutations in the MYO5B gene, leading to intractable diarrhea often necessitating intestinal transplantation (ITx). Among our cohort of 28 MVID patients, 8 developed a cholestatic liver disease akin to progressive familial intrahepatic cholestasis (PFIC). Our aim was to investigate the mechanisms by which MYO5B mutations affect hepatic biliary function and lead to cholestasis in MVID patients. Clinical and biological features and outcome were reviewed. Pretransplant liver biopsies were analyzed by immunostaining and electron microscopy. Cholestasis occurred before (n = 5) or after (n = 3) ITx and was characterized by intermittent jaundice, intractable pruritus, increased serum bile acid (BA) levels, and normal gamma-glutamyl transpeptidase activity. Liver histology showed canalicular cholestasis, mild-to-moderate fibrosis, and ultrastructural abnormalities of bile canaliculi. Portal fibrosis progressed in 5 patients. No mutation in ABCB11/BSEP or ATP8B1/FIC1 genes were identified. Immunohistochemical studies demonstrated abnormal cytoplasmic distribution of MYO5B, RAB11A, and BSEP in hepatocytes. Interruption of enterohepatic BA cycling after partial external biliary diversion or graft removal proved the most effective to ensure long-term remission. CONCLUSION MVID patients are at risk of developing a PFIC-like liver disease that may hamper outcome after ITx. Our results suggest that cholestasis in MVID patients results from (1) impairment of the MYO5B/RAB11A apical recycling endosome pathway in hepatocytes, (2) altered targeting of BSEP to the canalicular membrane, and (3) increased ileal BA absorption. Because cholestasis worsens after ITx, indication of a combined liver ITx should be discussed in MVID patients with severe cholestasis. Future studies will need to address more specifically the effect of MYO5B dysfunction in BA homeostasis.

Abstract
Background Pulmonary alveolar proteinosis (PAP) is very rare in children. Only a few small series have been published, with little information about long-term progression. The objective of our study was to describe the clinical, radiological and pathological features, and the long-term course of PAP in a cohort of 34 children from La Réunion Island. Methods Data were retrospectively collected from medical files. Radiological and pathological elements were reviewed by two pediatric radiologists and three pathologists, respectively. Results Thirteen cases were familial and 32/34 (94%) cases were family connected. Disease onset occurred in the first six months of life in 82% of the patients. Thoracic computed tomography scans showed the typical “crazy-paving” pattern in 94% of cases. Respiratory disease was associated with a liver disorder, with the detection of liver enlargement at diagnosis in 56% of cases. The course of the disease was characterized by frequent progression to chronic respiratory insufficiency, accompanied by the appearance of cholesterol granulomas and pulmonary fibrosis. Overall prognosis was poor, with a mortality of 59% and an overall five-year survival rate from birth of 64%. Whole-lung lavages were performed in 21 patients, with no significant effect on survival. Liver disease progressed to cirrhosis in 18% of children, with no severe complication. Conclusions PAP in children from la Réunion Island is characterized by an early onset, associated liver involvement, poor prognosis and frequent progression to lung fibrosis, despite whole-lung lavages treatment. The geographic clustering of patients and the detection of many familial links between most of the cases strongly suggest a genetic etiology, with an autosomal recessive mode of inheritance.

Abstract
BACKGROUND & AIMS Chronic intestinal failure (CIF) requires long term parenteral nutrition (PN) and, in some patients, intestinal transplantation (ITx). Indications and timing for ITx remain poorly defined. In the present study we aimed to analyze causes and outcome of children with CIF. METHODS 118 consecutive patients referred to our institution were assessed by a multidisciplinary team and four different categories were defined retrospectively based on their clinical course: Group 1: patients with reversible intestinal failure; group 2: patients unsuitable for ITx, group 3: patients listed for ITx; group 4: patients stable under PN. Analysis involved comparison between groups for nutritional status, central venous catheter (CVC) related complications, liver disease, and outcome after transplantation by using non parametric tests, Mann-Whitney tests, Kruskal-Wallis, Wilcoxon signed rank tests and chi square distribution for percentage. RESULTS 118 children (72 boys) with a median age of 15 months at referral (2 months-16 years) were assessed. Etiology of IF was short bowel syndrome [n = 47], intractable diarrhea of infancy [n = 37], total intestinal aganglionosis [n = 18], and chronic intestinal pseudoobstruction [n = 17]. Most patients (89.8%) were totally PN dependent, with 48 children (40.7%) on home-PN prior to admission. Nutritional status was poor with a median body weight at -1.5 z-score (ranges: -5 to +2.5) and median length at -2.0 z-score (ranges: -5.5 to +2.3). The mean number of CVC inserted per patient was 5.2 (range 1-20) and the mean number of CRS per patient was 5.5 (median: 5; range 0-12) Fifty-five patients (46.6%) had thrombosis of ≥2 main venous axis. At admission 34.7% of patients had elevated bilirubin (≥50 μmol/l), and 19.5% had platelets <100,000/ml, and 15% had both. Liver biopsy performed in 79 children was normal (n = 4), or showed F1 or F2 fibrosis (n = 29), bridging fibrosis F3 (n = 20), or cirrhosis (n = 26). Group 1 included 10 children finally weaned from PN (7-years survival: 100%). Group 2 included 12 children with severe liver disease and associated disorders unsuitable for transplantation (7-years survival: 16.6%). Group 3 included 66 patients (56%) who were listed for small bowel or liver-small bowel transplantation, 62/66 have been transplanted (7 years survival: 74.6%). Factors influencing outcome after liver-ITx were body weight (p < .004), length (p < .001), pre-Tx bilirubin plasma level (p < .001) and thrombosis (p < .01) for isolated ITx, Group 4 included 30 children (25.4%) with irreversible IF considered as potential candidates for isolated ITx. Four children were lost from follow up and 3 died within 2 years (survival 88.5%). Among potential candidates, the following parameters improved significantly during the first 12 months of follow up: Body weight (p.0001), length (p < .0001) and bilirubin (p < .0001). CONCLUSIONS many patients had a poor nutritional status with severe complications especially liver disease. PN related complications were the most relevant indication for ITx, but also a negative predictor for outcome. Early patient referral for Tx-assessment might help to identify and separate children with irreversible IF from children with transient IF or uncomplicated long-term PN, allowing to adapt a patient-based treatment strategy including or not ITx.

Abstract
Simpson-Golabi-Behmel syndrome type 1 (SGBS1) -OMIM 312870- is a rare X-linked inherited overgrowth syndrome caused by a loss of function mutation in the GPC3 gene. Affected patients present a variable phenotype with pre- and post-natal macrosomia, distinctive facial dysmorphism, organomegaly, and multiple congenital anomalies. Intellectual disability is not constant. About 10% of patients have an increased risk of developing embryonic tumors in early childhood. Only one case of biliary disease has been described so far. GPC3 is localized on Xq26. It encodes for glypican 3, a heparan sulfate proteoglycan, which among its different known roles, negatively regulates liver regeneration and hepatocyte proliferation. This report concerns a male with a SGBS1, carrier of a GPC3 pathogenic mutation, and neonatal liver disease, who developed an early biliary cirrhosis. Together with the associated risk of cancer and developmental delay, liver transplantation was discussed and then successfully performed at the age of 19 months. A hypothesis on the role of GPC3 in the patient's liver disease is also proposed.

Abstract
BACKGROUND Asphyxiating Thoracic Dysplasia (ATD) belongs to the short rib polydactyly group and is characterized by a narrow thorax, short long bones and trident acetabular roof. Other reported features include polydactyly, renal, liver and retinal involvement. To date, mutations in IFT80, DYNC2H1, TTC21B and WDR19 have been reported in ATD. The clinical and molecular heterogeneity leads to difficulties in the evaluation of the long-term prognosis. METHODS We investigated 53 ATD cases (23 living cases and 30 fetuses) from 39 families. They benefited from a combined approach of deep phenotyping and IFT80 and DYNC2H1 molecular screening. RESULTS Among the 23 postnatal cases, pulmonary insufficiency was noted in 60% of cases, with tracheotomy requirement in five cases. Renal and liver diseases occurred respectively in 17% and 22% of cases, whereas retinal alteration was present in 50% of cases aged more than 5 years. We identified DYNC2H1 mutations in 23 families (59%) and IFT80 mutations in two families (5%). However, in six families, only one heterozygote mutation in either IFT80 or DYNC2H1 was identified. Finally, the two genes were excluded in 14 families (36%). CONCLUSIONS We conclude that DYNC2H1 is a major gene responsible for ATD, while IFT80 is rarely involved. The presence of only one mutation in six families and the exclusion of the two genes in 14 families support the involvement of other causal cilia genes. The long-term follow up emphasizes that the pulmonary prognosis is probably less pejorative and retinal involvement more frequent than previously thought.

Abstract
Congenital tufting enteropathy (CTE) is a rare and severe enteropathy recently ascribed to mutations in the epcam gene. Here we establish SPINT2, previously ascribed to congenital sodium diarrhea, as a second gene associated with CTE and report molecular and immunohistochemistry data in 57 CTE patients. Inclusion criteria were early onset diarrhea and intestinal insufficiency with the typical histological CTE abnormalities. The clinical phenotype was registered, the entire coding regions of epcam and SPINT2 sequenced, and immunostaining of EpCAM and SPINT2 performed on intestinal biopsies. An epcam mutation was involved in 41 patients (73 %) who mainly displayed isolated digestive symptoms. Mutations severely affected gene expression since the EpCAM signal on intestinal tissues was either undetectable or low and irregular. Twelve other patients (21 %) carried mutations in SPINT2, and were phenotypically characterized by systematic association with keratitis (p < 10(-4)) and, for half of them, with choanal atresia (p < 10(-4)). Dependency on parenteral nutrition (PN) was comparable in patients with epcam or SPINT2 mutations, but the frequent epcam mutation c.556-14A>G (abnormal splicing) was significantly associated with a better outcome (p = 0.032) with milder PN dependency to weaning in some cases. Finally, four patients (7 %) with isolated digestive symptoms had no detectable epcam or SPINT2 mutation. Two candidate genes, Elf3 and Claudin7, were excluded from this population. Our study allows us to separate CTE patients into at least three genetic classes, each with specific phenotypes. The genetics approach raises the question of the distinction between two congenital enteropathies. Our findings should help improve the diagnosis of CTE, guide toward strategies of long-term PN management, and limit indications for intestinal transplantation to life-threatening PN complications.

Abstract
The causes of Reye-like syndrome are not completely understood. Dihydrolipoamide dehydrogenase (DLD or E3) deficiency is a rare metabolic disorder causing neurological or liver impairment. Specific changes in the levels of urinary and plasma metabolites are the hallmark of the classical form of the disease. Here, we report a consanguineous family of Algerian origin with DLD deficiency presenting without suggestive clinical laboratory and anatomopathological findings. Two children died at birth from hepatic failure and three currently adult siblings had recurrent episodes of hepatic cytolysis associated with liver failure or Reye-like syndrome from infancy. Biochemical investigation (lactate, pyruvate, aminoacids in plasma, organic acids in urine) was normal. Histologic examination of liver and muscle showed mild lipid inclusions that were only visible by electron microscopy. The diagnosis of DLD deficiency was possible only after genome-wide linkage analysis, confirmed by a homozygous mutation (p.G229C) in the DLD gene, previously reported in patients with the same geographic origin. DLD and pyruvate dehydrogenase activities were respectively reduced to 25% and 70% in skin fibroblasts of patients and were unresponsive to riboflavin supplementation. In conclusion, this observation clearly supports the view that DLD deficiency should be considered in patients with Reye-like syndrome or liver failure even in the absence of suggestive biochemical findings, with the p.G229C mutation screening as a valuable test in the Arab patients because of its high frequency. It also highlights the usefulness of genome-wide linkage analysis for decisive diagnosis advance in inherited metabolic disorders.
