Rare cholestatic childhood diseases:Advances in clinical care

Biliary atresia, severe FIC1 and severe BSEP deficiency (also known as PFIC1 and PFIC2) are rare cholestatic childhood diseases. The aim of this thesis was to identify novel targets of intervention for improving the prognosis of patients suffering these diseases. The studies conducted in this thesis demonstrate that national or global collaboration allows to obtain novel insights in the natural history of rare liver diseases and their responsiveness to specific treatments. These insights have already led to patient-tailored changes in treatments for these diseases and are expected to have more impact in the near future, not only for the care and counselling of individual patients but also for understanding the pathophysiology of these rare diseases. The studies underline the value, if not the necessity, of collaborative efforts of clinicians, authorities and patient advocates for improving the prognosis of patients with rare diseases and for the advancement of science

Etiology and Outcome of Adult and Pediatric Acute Liver Failure in Europe

Acute liver failure (ALF) is rare but life-threatening. Common causes include intoxications, infections, and metabolic disorders. Indeterminate etiology is still frequent. No systematic data on incidence, causes, and outcome of ALF across Europe are available. Via an online survey we reached out to European Reference Network Centers on rare liver diseases. Numbers and etiology of ALF cases during 2020 were retrieved and diagnostic and treatment availabilities assessed. In total, 455 cases (306 adult, 149 pediatric) were reported from 36 centers from 20 countries. Intoxication was the most common cause in adult and pediatric care. The number of cases with indeterminate etiology is low. Diagnostic tools and specific treatment options are broadly available within this network. This is the first approach to report on etiology and outcome of ALF in the pediatric and adult population in Europe. High diagnostic yield and standard of care reflects the expert status of involved centers.</p

EASL-ERN position paper on liver involvement in patients with Fontan-type circulation

Fontan-type surgery is the final step in the sequential palliative surgical treatment of infants born with a univentricular heart. The resulting long-term haemodynamic changes promote liver damage, leading to Fontan-associated liver disease (FALD), in virtually all patients with Fontan circulation. Owing to the lack of a uniform definition of FALD and the competitive risk of other complications developed by Fontan patients, the impact of FALD on the prognosis of these patients is currently debatable. However, based on the increasing number of adult Fontan patients and recent research interest, the European Association for The Study of the Liver and the European Reference Network on Rare Liver Diseases thought a position paper timely. The aims of the current paper are: (1) to provide a clear definition and description of FALD, including clinical, analytical, radiological, haemodynamic, and histological features; (2) to facilitate guidance for staging the liver disease; and (3) to provide evidence- and experience-based recommendations for the management of different clinical scenarios.</p

Severe acute hepatitis and acute liver failure of unknown origin in children : a questionnaire-based study within 34 paediatric liver centres in 22 European countries and Israel, April 2022

Publisher Copyright: © 2022 European Centre for Disease Prevention and Control (ECDC). All rights reserved.To detect potential concern about severe acute hepatitis in children, we conducted a survey among 50 ERN RARE-LIVER centres. By 26 April 2022, 34 centres, including 25 transplant centres, reported an estimated median of 3-5, 0-2 and 3-5 cases in 2021, 2020 and 2019 and a mean of 2 (range: 0-8) cases between January and April 2022 (mean in 10 large liver transplant centres: 3). Twelve centres reported suspicion of an increase, but no rise. Following a report by the United Kingdom (UK) on 5 April 2022 on the occurrence of cases of severe acute hepatitis in children aged 16 years or under, the World Health Organization (WHO) raised concerns about the possibility of an epidemic [1,2]. By 21 April, 169 possible or confirmed cases were reported fulfilling the WHO case definition [3]. The cause of the hepatitis is unknown but a link to a virus infection has been suggested due to the epidemiological pattern of cases [4,5]. The hepatitis can progress to paediatric acute liver failure (pALF) necessitating urgent liver transplantation to avoid multi-organ failure [6]. We intended to assess whether a rise in incidence of severe acute hepatitis or pALF could be observed between 1 January and 26 April 2022 in comparison to previous years, within the European Reference Network on Hepatological Diseases (ERN RARE-LIVER) [7].Peer reviewe

Partial Biliary Diversion May Promote Long-Term Relief of Pruritus and Native Liver Survival in Children with Cholestatic Liver Diseases

Introduction Rare cholestatic liver diseases may cause debilitating pruritus in children. Partial biliary diversion (PBD) may relieve pruritus and postpone liver transplantation which is the only other alternative when conservative treatment fails. The aim was to report long-term outcome after PBD in a population of 26 million people during a 25-year period. Materials and Methods This is an international, multicenter retrospective study reviewing medical journals. Complications were graded according to the Clavien-Dindo classification system. Results Thirty-three patients, 14 males, underwent PBD at a median of 1.5 (0.3-13) years at four Nordic pediatric surgical centers. Progressive familial intrahepatic cholestasis was the most common underlying condition. Initially, all patients got external diversion, either cholecystojejunostomy (25 patients) or button placed in the gallbladder or a jejunal conduit. Early complications occurred in 14 (42%) patients, of which 3 were Clavien-Dindo grade 3. Long-term stoma-related complications were common (55%). Twenty secondary surgeries were performed due to stoma problems such as prolapse, stricture, and bleeding, or conversion to another form of PBD. Thirteen children have undergone liver transplantation, and two are listed for transplantation due to inefficient effect of PBD on pruritus. Serum levels of bile acids in the first week after PBD construction were significantly lower in patients with good relief of pruritus than in those with poor effect (13 [2-192] vs. 148 [5-383] mu mol/L; p =0.02). Conclusion PBD may ensure long-term satisfactory effect on intolerable pruritus and native liver survival in children with cholestatic liver disease. However, stoma-related problems and reoperations are common.Peer reviewe

Indeterminate pediatric acute liver failure:Clinical characteristics of a temporal cluster of five children in the Netherlands in the spring of 2022

There is increasing global concern of severe acute hepatitis of unknown etiology in young children. In early 2022, our center for liver transplantation in the Netherlands treated five children who presented in short succession with indeterminate acute liver failure. Four children underwent liver transplantation, one spontaneously recovered. Here we delineate the clinical course and comprehensive diagnostic workup of these patients. Three of five patients showed a gradual decline of liver synthetic function and had mild neurological symptoms. Their clinical and histological findings were consistent with hepatitis. These three patients all had a past SARS-CoV-2 infection and two of them were positive for adenovirus DNA. The other two patients presented with advanced liver failure and encephalopathy and underwent dialysis as a bridge to transplantation. One of these children spontaneously recovered. We discuss this cluster of patients in the context of the currently elevated incidence of severe acute hepatitis in children
