AIM: The human leucocyte antigen (HLA) allele and haplotype frequencies of the Finnish population are unique because of the restricted and homogenous gene population. There are no published data on HLA genotype associations in paediatric autoimmune liver diseases in Scandinavia. This study characterised the HLA genotypes of children with autoimmune liver or biliary disease in Finland. METHODS: The study cohort comprised 19 paediatric patients (13 female) aged three years to 15 years treated for autoimmune liver or biliary disease at the Children's Hospital, Helsinki University Hospital, between 2000 and 2011, and followed up for four years and three months to 14...

OBJECTIVES: Autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC) are progressive immune-mediated inflammatory diseases that may require liver transplant (LT). Outcomes in children undergoing LT for these diseases are poorly studied in the Pediatric End Stage Liver Disease (PELD) era. We aimed to characterize the outcome of LT in children with AIH and PSC. METHODS: Children ≤18 years with PSC or AIH who had a first, isolated LT from 2002-2012 were identified from the UNOS database...

BACKGROUND: Sclerosing cholangitis (SC) is a chronic cholestatic hepatobiliary disease with uncertain long-term prognosis in pediatric patients. This study aimed to evaluate long-term results in children with SC according to the types of SC. METHODS: We retrospectively followed up 25 children with SC over a period of 4-17 years (median 12). The diagnosis of SC was based on biochemical, histological and cholangiographic findings. Patients fulfilling diagnostic criteria for probable or definite autoimmune hepatitis at the time of diagnosis were defined as having autoimmune sclerosing cholangitis (ASC); other patients were included in a group of primary sclerosing cholangitis (PSC)...

BACKGROUND & AIMS: Neonatal sclerosing cholangitis (NSC) is a severe neonatal-onset cholangiopathy commonly leading to liver transplantation (LT) for end-stage liver disease in childhood. Liver biopsy findings histopathologically resemble those in biliary atresia (BA); however, in NSC extrahepatic bile ducts are patent, whilst in BA their lumina are obliterated. NSC is commonly seen in consanguineous kindreds, suggesting autosomal recessive inheritance. METHODS: From 29 NSC patients (24 families) identified, DNA was available in 24 (21 families)...

Neonatal sclerosing cholangitis (NSC) is a rare biliary disease leading to liver transplantation in childhood. Patients with NSC and ichtyosis have already been identified with a CLDN1 mutation, encoding a tight-junction protein. However, for the majority of patients, the molecular basis of NSC remains unknown. We identified biallelic missense mutations or in-frame deletion in DCDC2 in four affected children. Mutations involve highly conserved amino acids in the doublecortin domains of the protein. In cholangiocytes, DCDC2 protein is normally located in the cytoplasm and cilia, whereas in patients the mutated protein is accumulated in the cytoplasm, absent from cilia, and associated with ciliogenesis defect...

BACKGROUND: Shigatoxin-associated haemolytic uremic syndrome (STEC-HUS) is the most frequent cause of acute kidney injury in children worldwide. Extrarenal manifestations are the main determinants for both, short- and long-term prognosis of patients with STEC-HUS. PATIENTS: 46 patients treated over the last 10 years for STEC-HUS in a single center. METHODS: This retrospective study analysed the incidence and outcome of extrarenal manifestations in our cohort of children with STEC-HUS...

Approximately 10% of children with autoimmune hepatitis (AIH) and 30% of those with sclerosing cholangitis (SC) require liver transplantation (LT). LT is indicated in patients who present with fulminant hepatic failure (ie, with encephalopathy) and in those who develop end-stage liver disease despite treatment. After LT, recurrent AIH is reported in approximately 30% of patients and recurrent SC in up to 50%. Diagnosis of recurrence is based on biochemical abnormalities, seropositivity for autoantibodies, interface hepatitis on histology, steroid dependence, and, for SC, presence of cholangiopathy...

Jaundice with pruritus is a manifestation of cholestasis. The defective biliary drainage causes accumulation of substances that are usually excreted in bile, which in turn causes pruritus. The exact nature of the pruritogen is under evaluation. However, lysophosphatidic acid is the current favourite. The causes of cholestasis can be broadly classified as intra or extrahepatic, with intrahepatic disorders being more often associated with pruritus. Cholestatic phase of acute viral hepatitis, progressive familial intrahepatic cholestasis, syndromic and non-syndromic paucity of intralobular bile ductules, drug induced cholestasis and sclerosing cholangitis (SC) are the common causes in children...

Coeliac disease and inflammatory bowel disease are chronic inflammatory conditions of gastrointestinal tract with complex aetiology with genetic, environmental and immunological factors contributing to its pathogenesis. It was noted that immune-mediated disorders often coexist. There is well-known association between coeliac disease and type 1 diabetes and ulcerative colitis and primary sclerosing cholangitis. However, growing body of literature suggests the association between coeliac disease and inflammatory bowel disease, particularly ulcerative colitis...

Infliximab (IFX) is commonly used to induce and maintain remission in inflammatory bowel disease (IBD). We report the first 2 cases of children with ulcerative colitis who had normal liver transaminases before IFX and were diagnosed with immunomediated hepatitis after IFX induction. Both the cases had negative antibodies for antinuclear, smooth muscle, and liver kidney microsome, with 1 patient having positive autoimmune serology (dsDNA) and overlap primary sclerosing cholangitis. IFX was discontinued and transaminases normalized without steroid administration...

OBJECTIVES: This is a cohort study of 134 children and adolescents with a known diagnosis of autoimmune hepatitis (AIH). During follow-up, some of them developed autoimmune sclerosing cholangitis (ASC). This study describes the characteristics of the patients upon diagnosis, and their response to treatment and any complications, and compares the patients who developed ASC during follow-up (ASC group) with those who did not (AIH group). METHODS: A total of 73.1% of the patients were girls with a median age upon diagnosis of 10...

Biliary atresia (BA) is a rare and severe inflammatory and obliterative cholangiopathy that affects both extra- and intrahepatic bile ducts. BA symptoms occur shortly after birth with jaundice, pale stools and dark urines. The prognosis of BA has dramatically changed in the last decades: before the Kasai operation most BA patients died, while nowadays with the sequential treatment with Kasai operation±liver transplantation BA patient survival is close to 90%. Early diagnosis is very important since the chances of success of the Kasai procedure decrease with time...

BACKGROUND: Some patients present with features of both primary biliary cirrhosis (PBC) or primary sclerosing cholangitis (PSC) on the one hand and autoimmune hepatitis (AIH) on the other hand, either simultaneously or consecutively. The term 'overlap syndrome (OS)' is used to describe these settings, but lack of universal agreement on what precisely constitutes an OS has generated considerable confusion. The low prevalence of OS (roughly 10% of PBC or PSC) has made it impracticable to perform randomized controlled trials...

For many patients with autoimmune hepatitis (AIH), the presence of extrahepatic features is well recognised both at the time of presentation and during long-term follow-up. Concomitant 'autoimmune disorders' have been described in 20-50% of patients with AIH, both in adults and children. Indeed, the presence of these associated phenomena has been incorporated into both the original and revised International AIH group scoring systems as an aid to codifying the diagnosis. In acute index presentations, non-specific joint pains sometimes flitting in nature have been reported in 10-60% of patients, and while joint swelling is uncommon, rheumatoid arthritis and mixed connective tissue disease have been reported in 2-4% of patients with AIH...

Autoimmune hepatitis (AIH) fulfills the generally accepted contemporary criteria of an autoimmune liver disease: the presence of autoantibodies and autoreactive T cells, a female gender bias, association with other autoimmune diseases, response to immunosuppressive therapy and strong associations with the major histocompatibility complex HLA loci. It occurs worldwide in both children and adults and is marked by both etiopathogenic and clinical heterogeneity, differing from the other putative autoimmune liver diseases, primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC), albeit occasionally presenting with overlapping features of PBC or PSC...
