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.

Abstract
OBJECTIVE To assess and characterize health care resource utilization (HRU) in children with the rare, genetic, multisystem disorder, Alagille syndrome. STUDY DESIGN This retrospective analysis reviewed commercially insured and Medicaid-insured claims from October 1, 2015 to December 31, 2019 to assess HRU in patients with Alagille syndrome. As there is no specific International Classification ofDiseases-10 code for Alagille syndrome, patients were identified using the following algorithm: ≥1 claim with diagnosis code Q44.7 (other congenital malformations of the liver); <18 years of age, with no history of biliary atresia (International Classification ofDiseases-10 code: Q44.2); and ≥6 months of insurance eligibility prior to diagnosis. HRU was summarized per patient per year over all available claims postdiagnosis. RESULTS A total of 171 commercially insured and 215 Medicaid-insured patients with Alagille syndrome were available for analysis. Annually, commercially insured and Medicaid-insured patients averaged 31 medical visits (range, 1.5-237) and 48 medical visits (range, 0.7-690), respectively. The most common visits were outpatient with the majority encompassing lab/imaging and primary care visits (commercially insured: 21 [range, 0.0-183]; Medicaid-insured: 26 [range, 0.0-609]). Inpatient visits were the highest driver of costs in both the commercial and Medicaid populations. CONCLUSIONS Patients with Alagille syndrome have a substantial HRU burden driven largely by numerous outpatient visits and costly inpatient stays. Given the complexity and variability of Alagille syndrome presentation, patients may benefit from multidisciplinary and subspecialized care.

Abstract
PURPOSE OF REVIEW Living donor liver transplantation (LT) has been increasingly recognized as an effective treatment modality with excellent patient survival. Indications for LT have evolved not only for cholestatic liver disease, but also metabolic liver diseases. Living donor selection, particularly for pediatric inherited disease, is essential to prevent morbidity, both in the donor and recipient. RECENT FINDINGS Based on 30 years of experience in pediatric living donor LT in Japan, we could identify marginal parental living donors who have potential risks following LT, including heterozygous mothers with ornithine transcarbamylase deficiency, heterozygous protein C deficiency, heterozygous hypercholesterolemia, heterozygous protoporphyria, asymptomatic parental donors with paucity of intrahepatic bile duct, and human leukocyte antigen-homozygous parental donors. SUMMARY Although these situations seem rare due to infrequency of the condition, careful living donor evaluation is required to optimize the outcomes for pediatric recipients. In the setting of an appropriate selection of a living donor, we should avoid any additional hazards, given that the procedure itself has risks for a healthy individual.

Abstract
Alagille syndrome, caused by mutations in the gene encoding Jagged1 (JAG1), a ligand in the Notch signaling pathway, is an autosomal dominant disorder with developmental abnormalities affecting the liver, heart, eyes, face and skeleton. The aim of the present study is try to disclose the clinical features, management and outcomes of pulmonary artery stenosis associated with Alagille syndrome. By comprehensive literature retrieval, 38 articles involving 401 patients were recruited for this study. The pertinent variables closely related to pulmonary artery stenosis in patients with Alagille syndrome were comprehensively analyzed by following the PRISMA guidelines. The management of pulmonary artery pathologies, especially a severe type of pulmonary artery stenosis in Alagille syndrome, is a concerned matter. Publications of literature retrieval of recent 3 decades were the study material of this article. The pulmonary artery pathologies, especially the severe type of pulmonary artery stenosis in Alagille syndrome, warrant surgical or interventional treatments. After the procedures, the right ventricular to left ventricular pressure ratio was reduced by 25%. There were no intergroup differences in terms of recovery, reintervention and mortality rates between interventionally and surgically treated patients. Transcatheter treatment is preferable due to less trauma. Surgical treatment of pulmonary artery stenosis can be performed currently with intracardiac defect repair.

Abstract
Alagille syndrome (ALGS) is an autosomal dominant disorder characterized by involvement of various organ systems. It predominantly affects the liver, skeleton, heart, kidneys, eyes and major blood vessels. With myriads of presentations across different age groups, ALGS is usually suspected in infants presenting with high gamma glutamyl transpeptidase cholestasis and/or congenital heart disease. In children it may present with decompensated cirrhosis, intellectual disability or short stature, and in adults vascular events like stroke or ruptured berry aneurysm are more commonly noted. Liver transplantation (LT) is indicated in children with cholestasis progressing to cirrhosis with decompensation. Other indications for LT include intractable pruritus, recurrent fractures, hepatocellular carcinoma and disfiguring xanthomas. Due to an increased risk of renal impairment noted in ALGS, these patients would require optimized renal sparing immunosuppression in the post-transplant period. As the systemic manifestations of ALGS are protean and a wider spectrum is being increasingly elucidated, a multidisciplinary team needs to be involved in managing these patients. Moreover, many basic-science and clinical questions especially with regard to its presentation and management remain unanswered. The aim of this review is to provide updated insights into the management of the multi-system involvement of ALGS.

Abstract
Alagille syndrome (ALGS) is an autosomal dominant disorder caused by pathogenic variants in JAG1 or NOTCH2, which encode fundamental components of the Notch signaling pathway. Clinical features span multiple organ systems including hepatic, cardiac, vascular, renal, skeletal, craniofacial, and ocular, and occur with variable phenotypic penetrance. Genotype-phenotype correlation studies have not yet shown associations between mutation type and clinical manifestations or severity, and it has been hypothesized that modifier genes may modulate the effects of JAG1 and NOTCH2 pathogenic variants. Medical management is supportive, focusing on clinical manifestations of disease, with liver transplant indicated for severe pruritus, liver synthetic dysfunction, portal hypertension, bone fractures, and/or growth failure. New therapeutic approaches are under investigation, including ileal bile acid transporter (IBAT) inhibitors and other approaches that may involve targeted interventions to augment the Notch signaling pathway in involved tissues.

Abstract
To analyze the clinical characteristics and the outcomes of living donor liver transplantation in children with Alagille syndrome (AGS). Clinical data of children with AGS who underwent liver transplantation between July 2009 and May 2019 in our unit were retrospectively analyzed. Primary end-points were patient and graft survival. Ten children with AGS underwent living donor liver transplantation at a median age of 28 months (range, 12-84 months). Jaundice was the most common initial symptom and was noted after a median duration of 20 days after birth (range, 7-60 days). Two patients had undergone Kasai porto-enterostomy for misdiagnosis of biliary atresia. The most common indication for transplantation was severe pruritus with poor quality of life. Explant livers in three children showed cirrhosis with early well-differentiated hepatocellular carcinoma. We have 100% patient and graft survival at a mean follow-up of 32 months (range 3-72 months). The median z-score for weight and height at liver transplantation was -2.66 (range: -6.44 to -0.9) and -3.6 (range: -7.96 to -0.93) while at follow-up was -1.7 (range: -3.4 to -0.35) and -2.1 (range: -3.9 to -1.4), respectively. The estimated glomerular filtration rate was normal pretransplant and follow-up. This is the first series of LDLT for Alagille syndrome in the Indian sub-continent. We report excellent post-transplant outcomes in contrast to outcomes reported from Western literature.

Outcomes of liver transplantation for Alagille syndrome after Kasai portoenterostomy: Alagille Syndrome with agenesis of extrahepatic bile ducts at porta hepatis. J Pediatr Surg 2019; 54:2387-2391. [PMID: 31104835 DOI: 10.1016/j.jpedsurg.2019.04.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Revised: 03/23/2019] [Accepted: 04/19/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Alagille syndrome (ALGS) is an autosomal dominant disorder, characterized by a paucity of intrahepatic bile ducts, resulting in significant cholestasis, and peculiar extrahepatic features. Some ALGS patients show a considerable overlap with biliary atresia (BA), and they can undergo Kasai procedure. The purpose of this study is to show the manifestations of BA overlapped ALGS cases in our institution, and to compare the outcomes of ALGS patients following liver transplantation (LT) between those who previously underwent Kasai surgery (ALGS-Kasai group) and those who did not (ALGS-non-Kasai group). METHODS Medical records of ALGS patients who underwent LT in Kyoto University Hospital, Japan from January 1992 to March 2018 were analyzed. ALGS diagnosis was determined according to physical, radiologic, and histopathological findings. RESULTS Thirty-one patients were ascertained (ALGS-Kasai: 4 males and 5 females vs. ALGS-non-Kasai: 14 males and 8 females, p = 0.43). Of 31 ALGS patients, 96.8% of children had pulmonary artery stenosis, 54.8% showed facial features, 29% revealed skeletal anomalies and 9.7% demonstrated ocular anomalies. The age at LT was significantly younger in ALGS-Kasai than ALGS-non-Kasai group (1.47 [interquartile range (IQR), 0.75-1.92] vs. 5.1 [IQR, 1.4-9.29] years; p = 0.038). Overall patient survival did not significantly differ between ALGS-Kasai (88.9%) and ALGS-non-Kasai patients (86.4%) (p = 0.84). Furthermore, the 1-year, 5-year, and 10-year patient survival rates for ALGS-Kasai group were 100%, 88.9%, and 88.9%, respectively, whereas those for ALGS-non-Kasai group were 90.9%, 90.9%, and 86.4%, respectively, with p-values of 0.36, 0.90, and 0.84, respectively. CONCLUSIONS BA overlapped ALGS cases had neonatal progressive cholestasis which prompted Kasai procedure, and early liver dysfunction after Kasai led to performing LT. The ALGS-Kasai patients undergo LT at earlier ages than the ALGS-non-Kasai patients, however, overall patients' survival rates are similar between groups. Overall ALGS patients' survival rate after LT is considered high. LEVELS OF EVIDENCE Level III; Case-control study or Retrospective comparative study.

Abstract
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. Of these, 13 LDLTs (4.4%) for 12 AGS patients were performed. We classified the visceral artery anomalies into aneurysms and stenosis. RESULTS The overall incidence of visceral aneurysm was 2 of 12 recipients (16.7%) and included a SMA aneurysm in one patient and an IPDA aneurysm with a subsequent SPA aneurysm in one patient; the ages of the diagnosis of visceral aneurysm were 16.3, 21.1, and 21.7 y, respectively. An endovascular treatment was performed for a progressive IPDA saccular aneurysm (12.0 × 14.5 × 15.0 mm). The overall incidence of visceral artery stenosis was 7 of 12 recipients (58.3%) and the median age at the diagnosis of visceral artery stenosis was 15.5 y (range 1.7-22.9 y). All 3 AGS patients with RA stenosis suffered from renal dysfunction (eGFR of 51, 78, and 51 mL/min/1.73m2 ). CONCLUSION The morbidity of visceral artery anomalies is not negligible. The performance of periodic imaging examinations is necessary, even for infants, because it is difficult to detect visceral vascular anomalies in the infant stage.

Abstract
Alagille syndrome is a complex multisystem autosomal dominant disorder with a wide variability in penetrance of clinical features. A majority of patients have pathogenic mutations in either the JAG1 gene, encoding a Notch pathway ligand, or the receptor NOTCH2. No genotype-phenotype correlations have been found in any organ system. Liver disease is a major cause of morbidity in this population, whereas cardiac and vascular involvement accounts for most of the mortality. Current therapies are supportive, but the future is promising for the development of targeted interventions to augment Notch pathway signaling in involved tissues.

Abstract
OBJECTIVES The aim of the study was to describe long-term growth postpediatric liver transplantation and to conduct bivariate and multivariate analysis of factors that may predict post-transplantation growth in children who received a liver transplant from January 1999 to December 2008 at the Hospital for Sick Children. METHODS A retrospective cohort study was conducted with follow-up of up-to 10 years post-transplantation. Mean height and weight z scores and annual differences in mean z scores were plotted against time after transplantation. A 1-way analysis of variance was conducted. Multivariate and univariate Cox proportional hazards analyses were conducted to determine factors associated with reaching the 50th and 25th percentiles for height. RESULTS A total of 127 children met eligibility criteria. The mean height z score at time of transplantation was -2.21 which by the second year post-transplantation increased significantly to -0.66 (mean increase of 1.55 standard deviation units). There were no further significant increases in mean height z score from 2 years post-transplantation until the end of follow-up at year 10. In multivariate analysis, height at transplant was the most important predictor of linear growth post-transplantation. CONCLUSIONS Children who underwent liver transplantation had significant catch-up growth in the first 2 years post-transplantation followed by a plateau phase. Increased height z-score at transplantation is the most important predictor of long-term growth.

Abstract
Living-donor liver transplantation is an important component of all liver transplant programs especially in those that care for the pediatric population. Over the last 30 years, innovations in surgical technique have converted living donation from an experimental procedure to a standard of care. Many of these innovations occurred in countries where culturally, deceased donation is limited leaving no alternatives but living donation. The Organ Transplantation Center at the National Center for Child Health and Development (NCCHD) in Tokyo, Japan, was established in 2005 where we have generated some of those innovations and in so doing, have performed living-donor liver transplantation in over 400 children. Here we review the indications, technical details, and outcomes of that cohort.

Abstract
PURPOSE Infants with Alagille syndrome (AGS) are occasionally misdiagnosed as biliary atresia and subsequently undergo Kasai operation. The purpose of this study was to investigate the outcome of patients with AGS who had previously received Kasai operation during infancy. METHODS This retrospective study was conducted at the Department of Pediatrics, Samsung Medical Center. We compared the prognosis and mortality between those who had undergone Kasai operation during infancy (Kasai group) and those who had not (non-Kasai group). RESULTS Among the 15 children with AGS, five had received Kasai operation, while 10 had not. All subjects in the Kasai group revealed neonatal cholestasis, while 70% of the non-Kasai group showed neonatal cholestasis. Liver transplantation was performed in 100% (5/5) among the Kasai group, and 20.0% (2/10) among the non-Kasai group (p=0.007). Mortality was observed in 60.0% (3/5) among the Kasai group, and 10.0% (1/10) among the non-Kasai group (p=0.077). CONCLUSION Although overall mortality rate did not significantly differ between the two groups, the proportion of patients receiving liver transplantation was significantly higher in the non-Kasai group. The relatively worse outcome in AGS patients who had received Kasai operation may be due to the unfavorable influences of Kasai operation on the clinical course of AGS, or maybe due to neonatal cholestasis, irrespective of the Kasai operation.

Abstract
Metabolic diseases that involve the liver represent a heterogeneous group of disorders. Apart from the metabolic defect, the subject's liver functions may be normal. With the increasing need for organs, livers from donors with metabolic diseases other than familial amyloid polyneuropathy might be possibly used for transplantation. However, whether such livers qualify as grafts and how they might impact recipient outcome are still unanswered questions. This review of the literature summarizes current experience in the use of such grafts in the context of cadaveric, domino, and living-related liver transplantation.

Abstract
Cholestatic liver disease consists of a variety of disorders. Primary sclerosing cholangitis and primary biliary cirrhosis are the most commonly recognized cholestatic liver disease in the adult population, while biliary atresia and Alagille syndrome are commonly recognized in the pediatric population. In infants, the causes are usually congenital or inherited. Even though jaundice is a hallmark of cholestasis, it is not always seen in adult patients with chronic liver disease. Patients can have “silent” progressive cholestatic liver disease for years prior to development of symptoms such as jaundice and pruritus. In this review, we will discuss some of the atypical causes of cholestatic liver disease such as benign recurrent intrahepatic cholestasis, progressive familial intrahepatic cholestasis, Alagille Syndrome, biliary atresia, total parenteral nutrition induced cholestasis and cholestasis secondary to drug induced liver injury.

Abstract
BACKGROUND This study was carried out in Chang Gung Memorial Hospital-Kaohsiung Medical Center, Taiwan, with the aim of reviewing the characteristics and the outcome of liver transplantation (LT) in children with Alagille syndrome (AGS). METHODS We performed a retrospective analysis of transplant records of children diagnosed with AGS and undergoing LT between 1987 and 2010. RESULTS Nine patients underwent living donor LT. Cholestasis and characteristic facies were seen in all patients. Posterior embryotoxon was seen in 4/9 (44.4%), butterfly vertebrae in 3/9 (33.3%), heart defect (pulmonary stenosis in 2) in 3/9 (33.3%), and renal disease in 2/9 (22.2%) patients. Five cases had cholestasis prior to the age of 60 days, whereas four cases had cholestasis after 60 days of age. Iminodiacetic acid scans showed no excretion of isotope into the bowel in four cases and suggested a false diagnosis of biliary atresia. All patients underwent diagnostic laparotomy and liver biopsy. Results of liver biopsy showed characteristic features of paucity of interlobular bile ducts in all patients. Kasai portoenterostomy was not performed in any patient prior to being referred for LT. The mean age at the time of LT was 4.6 years. The 5-year overall survival rate after living donor LT was 88.9%. CONCLUSION Our conclusion is that the clinical features of AGS are informative. In addition, histological confirmation is important in the diagnosis. AGS children with severe liver disease had good prognoses with LT.

Abstract
Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT.

Abstract
The association of biliary atresia (BA) with congenital heart diseases has been extensively described, and there are a number of reports on the outcomes of patients in this group who undergo liver transplantation (LT). The intraoperative management and the timing of LT for patients with end-stage liver disease are matters of debate, especially when complex heart diseases are involved. This report describes the outcome after LT for a pediatric recipient with BA and hypoplastic left heart syndrome. The patient underwent Norwood-Sano and Glenn procedures for heart palliation before LT. He was cyanotic, was severely malnourished, and had complications secondary to chronic liver failure. At the time of transplantation, the child was 16 months old and weighed 5175 g. Despite the critical clinical scenario and the long hospitalization period, there were no cardiac, vascular, or biliary complications after LT. At the age of 48 months, the patient was awaiting the final cardiac repair. In conclusion, the presence of complex cardiac malformations may not be a contraindication to LT. An experienced surgical team and a multidisciplinary approach are key to a successful outcome.

Abstract
Alagille syndrome (ALGS) is a multisystem disorder that manifests as childhood cholestasis. Reports of liver transplantation (LT) for patients with ALGS have come largely from single centers, which have reported survival rates of 57% to 79%. The aim of this study was to determine LT outcomes for patients with ALGS. We performed a retrospective analysis of the Studies of Pediatric Liver Transplantation database, which contains information about 3153 pediatric LT recipients. Data were available for 91 patients with ALGS and for 236 age-matched patients with biliary atresia (BA). The frequency of complex cardiac anomalies was lower in the LT group with ALGS versus published ALGS series (5% versus 13%). The pretransplant glomerular filtration rate (GFR) was <90 mL/minute/1.73 m(2) in 18% of the LT patients with ALGS and in 5% of the LT patients with BA (P < 0.001). The height deficit at listing was worse for the ALGS patients (66%) versus the BA patients (22%). The 1-year patient survival rates were 87% for the ALGS patients and 96% for the BA patients (P = 0.002). The deaths in the ALGS group mostly occurred within the first 30 days. No pretransplant factors associated with death were identified in the ALGS group. A survival analysis revealed that biliary (P = 0.02), vascular (P < 0.001), central nervous system (CNS; P < 0.001), and renal complications (P < 0.001) after LT were associated with death in the ALGS group. Renal insufficiency in the ALGS patients worsened after LT, and at 1 year, GFR was <90 mL/minute/1.73 m(2) in 22% of the LT patients with ALGS but in only 8% of the patients with BA (P = 0.0014). More LT pediatric patients with ALGS either were currently receiving special education (50% versus 30% for BA patients, P = 0.02) or had received special education in the past (60% versus 36%, P = 0.01). Vascular, CNS, and renal complications were increased in the ALGS patients after LT, and this reflected multisystem involvement. Although the 1-year survival rate was modestly lower for the ALGS patients versus the BA patients, the clustering of deaths within the first 30 days is notable and warrants increased vigilance and further investigation.

Abstract
Alagille syndrome (ALGS, OMIM #118450) is an autosomal dominant disorder that affects multiple organ systems including the liver, heart, eyes, vertebrae, and face. ALGS is caused by mutations in one of two genes in the Notch Signaling Pathway, Jagged1 (JAG1) or NOTCH2. In this study, analysis of 21 Vietnamese ALGS individuals led to the identification of 19 different mutations (18 JAG1 and 1 NOTCH2), 17 of which are novel, including the third reported NOTCH2 mutation in Alagille Syndrome. The spectrum of JAG1 mutations in the Vietnamese patients is similar to that previously reported, including nine frameshift, three missense, two splice site, one nonsense, two whole gene, and one partial gene deletion. The missense mutations are all likely to be disease causing, as two are loss of cysteines (C22R and C78G) and the third creates a cryptic splice site in exon 9 (G386R). No correlation between genotype and phenotype was observed. Assessment of clinical phenotype revealed that skeletal manifestations occur with a higher frequency than in previously reported Alagille cohorts. Facial features were difficult to assess and a Vietnamese pediatric gastroenterologist was only able to identify the facial phenotype in 61% of the cohort. To assess the agreement among North American dysmorphologists at detecting the presence of ALGS facial features in the Vietnamese patients, 37 clinical dysmorphologists evaluated a photographic panel of 20 Vietnamese children with and without ALGS. The dysmorphologists were unable to identify the individuals with ALGS in the majority of cases, suggesting that evaluation of facial features should not be used in the diagnosis of ALGS in this population. This is the first report of mutations and phenotypic spectrum of ALGS in a Vietnamese population.

Abstract
Alagille syndrome (ALGS), also known as arteriohepatic dysplasia, is a multisystem disorder due to defects in components of the Notch signalling pathway, most commonly due to mutation in JAG1 (ALGS type 1), but in a small proportion of cases mutation in NOTCH2 (ALGS type 2). The main clinical and pathological features are chronic cholestasis due to paucity of intrahepatic bile ducts, peripheral pulmonary artery stenosis, minor vertebral segmentation anomalies, characteristic facies, posterior embryotoxon/anterior segment abnormalities, pigmentary retinopathy, and dysplastic kidneys. It follows autosomal dominant inheritance, but reduced penetrance and variable expression are common in this disorder, and somatic/germline mosaicism may also be relatively frequent. This review discusses the clinical features of ALGS, including long-term complications, the clinical and molecular diagnosis, and management.

Abstract
OBJECTIVES Alagille syndrome (AGS) frequently presents with neonatal jaundice and can mimic other causes of high gamma-glutamyl transpeptidase (GGT) cholestasis, most notably biliary atresia. As a result infants with AGS may undergo intraoperative cholangiogram and even Kasai procedure. The aim of the study was to assess the hepatic outcomes of children with AGS who underwent the Kasai procedure. PATIENTS AND METHODS A retrospective review of the AGS clinical database at the Children's Hospital of Philadelphia was performed to identify clinically defined patients with AGS who underwent a Kasai. A cohort of Alagille control subjects was selected with equivalent symptoms of neonatal jaundice and matched for age and presence of cardiac anomaly. JAGGED1-mutation analysis was performed on available samples. Clinical courses were reviewed. Fisher exact and t tests were used for analysis. RESULTS Of the 430 patients with AGS, 19 underwent a Kasai procedure (K). The control cohort (C) consisted of 36 patients. Total bilirubin measured between 6 and 10 weeks of age in each cohort was equivalent (K: 9.6 mg/dL, C: 8.7 mg/dL); GGT levels were higher in the control group (K:493.4 U/L, C:574.4 U/L). Of note, the Kasai cohort had a significantly larger number of liver transplants (K: 9 [47.3%], C: 5 [13.9%], P = 0.01) and sustained higher mortality (K: 6 [31.6%], C: 1 [2.8%], P = 0.005). There was no genotype-phenotype correlation between the mutations identified and patients who underwent Kasai. CONCLUSIONS These data suggest that the Kasai procedure, although appropriate for children with biliary atresia, does not benefit children with AGS and actually appears to worsen outcome. The current data suggest that the Kasai is not a marker for underlying severe liver disease, but the procedure itself may have a detrimental effect on outcome. An appropriate medical evaluation and particular consideration of AGS is essential before surgical referral in infants with high GGT cholestasis.

Abstract
UNLABELLED AGS is an inherited disorder involving the liver, heart, eyes, face, and skeleton. AIM To determine the outcome of LT in children with AGS compared to those with BA. METHODS Children with AGS and BA who had a LT between 10/1987 and 5/2008 were identified from the UNOS database. RESULTS Of 11 467 children who received a liver transplant, 461 (4.0%) had AGS and 3056 (26.7%) had BA. One- and five-yr patient survival was significantly lower in patients with AGS in comparison with patients with BA (AGS; 82.9%, 78.4%, BA; 89.9%, 84%, respectively). Early death (<30 days from transplant) was significantly higher in AGS than in BA. One- and five-yr graft survival was significantly lower in AGS than in BA (AGS; 74.7%, 61.5%, BA; 81.6%, 70.0%, respectively). Death from graft failure, neurological, and cardiac complications was significantly higher in patients with AGS than in patients with BA. Serum creatinine at transplant, prior LT, and cold ischemic time >12 h were identified as risk factors for death. CONCLUSION Children with AGS were older at the time of LT and their one- and five-yr patient and graft survival were significantly lower compared to BA. Risk factors for poor outcome in AGS after LT were identified.

Abstract
Alagille syndrome is a multisystem disorder in which progressive liver disease with persistent cholestasis and dramatic pruritus often warrant consideration for liver transplantation. The most important part of the transplant assessment is evaluation of the cardiac and renal involvement. Preoperatively, cardiac performance often must be tested with dynamic stress tests, mimicking hemodynamic changes during liver transplant. Many aspects of the syndrome including cholestasis, pruritus, and hypercholesterolemia improve posttransplant, but short stature is rarely significantly affected. One- and 5-year patient and graft survival after liver transplant is comparable to other elective indications, but effects of long-term immunosuppressants on evolution of other components of the syndrome, including vascular, bone, and renal disease, remain largely unknown.

Abstract
BACKGROUND Alagille syndrome (AS) is regarded as the most common cause of chronic cholestasis in childhood associated with specific phenotypic features in western countries. This study was undertaken to investigate the significance of AS in Chinese children with chronic cholestasis and to describe its clinical and histological features. METHODS From October 2004 to January 2007, 157 children who presented with conjugated jaundice from less than 3 months of age were admitted to a tertiary hospital in Shanghai. Investigations of the heart, spine, eyes and kidneys were conducted in 13 children who experienced prolonged cholestasis beyond 1 year of age after exclusion of biliary atresia and familial progressive intrahepatic cholestasis type 1 or 2. In patients with interlobular bile duct paucity, AS was diagnosed if 3 or more of the following 5 major features were present: cardiac murmur, posterior embryotoxon, butterfly-like vertebrae, renal abnormalities and characteristic faces. In patients without interlobular bile duct paucity or who did not receive liver biopsy, 4 or more features were required for the diagnosis. RESULTS Of the 13 children, 6 were diagnosed with AS at ages ranging from 1 year and 7 months to 3 years and 11 months. Jaundice was noticed in early infancy and then pruritus developed in all the 6 patients, of whom 5 presented with acholic stool and 4 had been misdiagnosed as having presumed biliary atresia by hepatobiliary scintigraphy or laparoscopic cholangiography. Biochemical examinations demonstrated increased concentration of total bile acid and hyperlipidemia. Interlobular bile duct paucity was demonstrated histologically in 5 patients who received liver biopsy. Vertebral abnormalities, heart murmur, characteristic faces and failure to thrive were found in all the 6 patients. Two patients had evidence of renal involvement. Micropenis, empty scrotum, and gall stone were seen in 1 patient. CONCLUSION AS is also an important cause of prolonged cholestasis in Chinese children. It is difficult to differentiate AS from biliary atresia. Liver biopsy and spine X-ray may be helpful in the early detection of AS.

Abstract
Although advances in the management of children with congenital cholestasis have enabled many to survive into adulthood with their native livers, even the most common of these conditions remains rare in adult hepatology practice. Among four congenital cholestatic syndromes (biliary atresia, Alagille syndrome, Caroli disease and congenital hepatic fibrosis, and progressive familial intrahepatic cholestasis), the published data on outcomes of the syndromes into adulthood suggest that a spectrum of severity of liver disease can be expected, from cirrhosis (almost universal in adults with biliary atresia who have not required liver transplantation) to mild and subclinical (eg, in the previously undiagnosed affected parent of an infant with Alagille syndrome). Complications associated with portal hypertension and nutritional deficiencies are common, and other associated features of the cholestatic syndrome may require appropriate attention, such as congenital heart disease in Alagille syndrome. Indications for liver transplantation include synthetic failure, progressive encephalopathy, intractable pruritus, recurrent biliary sepsis and recurrent complications of portal hypertension. Improved understanding of biliary physiology will hopefully translate into improved therapy for children and adults with cholestasis.

Abstract
Mutations in the JAG1 gene and the NOTCH2 gene cause Alagille syndrome. At present, however, genetic testing of Alagille syndrome is not commonly applied in clinical settings because the currently available assays are technically and financially demanding, mainly because of the size of the genes. In the present study, we optimized the highly sensitive and specific mutation scanning method automated denaturing high-performance liquid chromatography (DHPLC) to analyze the entire coding region of JAG1 and NOTCH2. The coding region was amplified by 69 primer pairs, all of which have the same cycling conditions, aliquoted on a 96-well format PCR plate. In this manner, all the exons were simultaneously amplified using a single block in a thermal cycler. We then wrote a computer script to analyze each segment of JAG1 and NOTCH2 by DHPLC in a serial manner using conditions that were optimized for each amplicon. The implementation of this screening method for JAG1 and NOTCH2 will help medical geneticists confirm their clinical impressions and provide accurate genetic counseling to the patients with Alagille syndrome and their families.

Abstract
Progressive familial intrahepatic cholestasis (PFIC) is a severe cholestatic liver disease of early life often requiring liver transplantation. Organ shortage leads to consider living-related liver transplantation. Because of possible partial metabolic defect in heterozygotes, the use of familial donors might be questionable. We therefore evaluated the safety of this procedure, for both donors and recipients. We compared a series of seven parental-children pairs, having participated in the living related liver transplant program for PFIC between 1994 and 2001, with that of a series of seven parental-children pairs, performed for biliary atresia (BA) during the same period. No primary graft dysfunction was observed. There was no difference in the course of transaminases, gamma-glutamyl transpeptidase and bilirubin levels after transplantation in both donor and recipient series. Thirteen recipients and 14 donors are alive and well 3-10 yr post-surgery. One PFIC recipient died nine months post-orthotopic liver transplantation from sepsis. We conclude that PFIC heterozygote status of the donor does not increase the risk of liver dysfunction in either recipients or donors, with a similar course compared with BA recipients and donors.

Abstract
An AGS is a dominant inherited multisystem disorder caused by mutations in the Notch signaling pathway (JAG1). In our center, 5.3% of liver transplantations (OLT) are performed in children with AGS. Some of the affected children fulfilled criteria for OLT, despite the absence of liver cirrhosis. The aim of our present study was to evaluate the indications and outcome for OLT in children with this complex disorder as clear criteria are difficult to establish in clinical practice. A total of 37 patients were included in a retrospective analysis. Twenty-four children underwent OLT for chronic end-stage liver failure (n = 8) or symptomatic liver disease (n = 16). Patient survival post-OLT was 91.7% after 1 yr, that of graft survival was 87.5%, respectively. Significant post-transplant vascular complications included a mid-aortic syndrome (n = 1) and severe lethal bleeding due to suspected vascular malformation (n = 1). Severe hypercholesterolemia (>800 mg/dL) and xanthomata resolved completely in affected patients. We conclude from our data that indications for OLT in AGS should be extended to patients with severe symptomatic liver disease, even in the absence of liver cirrhosis because of the significantly improved outcome after pediatric OLT in the last decade. Future studies must identify underlying mechanisms of hypercholesterolemia and vascular malformation.

Abstract
We described a case of Alagille syndrome with severe peripheral pulmonary artery stenosis and very high right ventricular pressure that underwent successful living-related liver transplantation without any peri-operative and mid-term postoperative complication because of this cardiac malformation. The aim of this report is to point out that the severe pulmonary artery stenosis may be a risk factor but not a contraindication to liver transplantation in patients with Alagille syndrome.

Abstract
Alagille syndrome (AS) is a dominantly inherited, multisystem disorder involving the liver, heart, eyes, face, and skeleton. From October 1997 through July 2004, 260 pediatric orthotopic liver transplantations (OLTx) were performed in 231 patients. This report describes 21 patients of median age 1.95 years (range, 0.7-16.7) who had alagille syndrome. We present the technical features of the OLTx, incidence and type of complications, medical conditions related to the syndrome, need for retransplantation, as well as patient and graft survival rates. A split liver technique was used in 16 patients (76%) who received a left lateral segment (LLS) graft whereas 7 patients (33%) received a whole liver. Only cadaveric donors were used. The major surgical complications requiring reintervention in 11 patients (52%) included biliary problems (19%) and vascular complications (17%). One case of hepatic artery thrombosis required retransplantation. Three recipients (14%) died. All other patients are alive with an actuarial survival rate of 90% at 1 year and 80% at 5 years. The actuarial graft survival rate is 85% at 1 year and 75% at 5 years. Patients with AS, despite the associated cardiovascular anomalies, can be treated successfully by a combined approach between cardiologist, radiologist, cardiothoracic, and liver transplant surgeons. With careful planning and operative management, the results are comparable with those obtained with other more common cholestatic diseases.
