Abstract
Sclerosing cholangitis (SC) is a rare chronic disorder characterised by inflammation and progressive obliterative fibrosis of the intrahepatic and/or extrahepatic bile ducts. Diagnosis is based on cholangiogram showing bile duct dilatation, narrowing and obliteration of the biliary tree, and histologically, on the presence of inflammatory bile duct damage leading to periductal fibrosis. In children the most common SC is associated with strong autoimmune features, overlapping with those of autoimmune hepatitis (AIH); this form is known as autoimmune sclerosing cholangitis, ASC. Conversely, primary SC (PSC), a condition in which the term "primary" indicates that aetiology and pathogenesis are unknown, is rare in paediatrics. Secondary SC (SSC) defines a cholangiopathy associated with an identifiable aetiology such as immunodeficiencies, infections or haematological disorders. ASC and PSC are strongly associated with inflammatory bowel disease (IBD). ASC responds biochemically well to immunosuppressive drugs and ursodeoxycholic acid (UDCA). Primary forms are exclusively managed with oral UDCA, while in the secondary forms the medical treatment depends on the underlying aetiology. Despite treatment, SC often progresses to biliary cirrhosis and end-stage liver disease requiring liver transplantation. The disease can recur after transplant. Better understanding of pathogenic mechanisms and better treatment modalities are needed to improve the prognosis of this invalidating hepatic disorder.

Abstract
Background and Objectives: Primary sclerosing cholangitis (PSC) is a rare cholestatic disease of the liver of unknown etiology, severe course and poor prognosis. PSC most often co-occurs with inflammatory bowel diseases (IBD), especially with ulcerative colitis (UC). The aim of the study was the analysis of the clinical course of primary sclerosing cholangitis in children, hospitalized in the Gastroenterology Unit in Katowice. Materials and Methods: The analysis included 30 patients, aged from 7 to 18 years, 21/30 boys (70%) and 9/30 girls (30%), diagnosed with PSC in the years 2009–2019. The analysis included the age at diagnosis, clinical symptoms, course of the disease, coexisting diseases, laboratory and imaging results, and complications. Results: The average age at diagnosis was 13 years. 22/30 (73.3%) patients suffered from UC, 4/30 (13.3%) were diagnosed with Crohn’s disease (CD), 2/30 (6.66%) with Eosinophilic Colitis (EC). 2/30 patients (6.66%) had no clinical evidence of coexistent IBD to date. In addition, 7/30 (23.3%) had an overlap syndrome of primary sclerosing cholangitis/autoimmune hepatitis. When PSC was detected before IBD (6/30–20%), patients had complications more often compared to those diagnosed with IBD first or PSC and IBD at the same time. At the moment of diagnosis 6/30 (20%) patients presented with abdominal pain, which was the most common symptom, 3/30 (10%) jaundice, while 17/30 (56.6%) were asymptomatic but had abnormal results of the laboratory tests. Conclusions: Monitoring liver markers in IBD patients is important since most PSC cases are asymptomatic and their elevation might be the first sign of the disease. Patients diagnosed with PSC before IBD diagnosis are more likely to have a more aggressive course of the disease.

Abstract
Juvenile sclerosing cholangitis is a rare chronic hepatobiliary disorder characterized by inflammation of the intra- and/or extrahepatic bile ducts, bile duct dilatation, narrowing and obliteration, and, histologically, by inflammatory bile duct damage leading to periductular fibrosis. The diagnosis is based on endoscopic retrograde cholangiopancreatography or magnetic resonance cholangiopancreatography. In children, it may be associated to a variety of systemic and hepatic conditions: thus, the term "primary" sclerosing cholangitis should be reserved for the rare cases without a known cause. Small duct disease is diagnosed in the presence of histological features diagnostic of sclerosing cholangitis and normal cholangiography. Autoimmune sclerosing cholangitis (ASC) is a form of sclerosing cholangitis with strong autoimmune features overlapping with those of autoimmune hepatitis (AIH). It is a well-recognized nosological entity in paediatrics, where it accounts for the majority of sclerosing cholangitis cases. It is as prevalent as AIH in children, is equally frequent in males and females, half of the patients have concomitant inflammatory bowel disease, virtually all patients have raised immunoglobulin G levels and positive anti-nuclear and/or anti-smooth muscle antibodies. Half of the ASC patients respond well to standard immunosuppressive treatment for AIH with the addition of ursodeoxycholic acid, but the transplant rate is higher than in AIH, and post-transplant recurrence is frequent. A number of open questions remain: are ASC and AIH distinct entities or different manifestations of the same condition? What is the role of histology? Is small duct disease a specific entity? What is the relationship between ASC and adult primary sclerosing cholangitis? What is the role of inflammatory bowel disease? In addition, validated diagnostic criteria for ASC are needed.

Abstract
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). The incidence of the following complications was studied: obstructive cholangitis, portal hypertension, advanced liver disease and death associated with the primary disease. RESULTS Fourteen (56%) patients had PSC and 11 (44%) had ASC. Patients with ASC were significantly younger at the time of diagnosis (12.3 vs 15.4 years, P=0.032) and had higher IgG levels (22.7 vs 17.2 g/L, P=0.003). The mentioned complications occurred in 4 (16%) patients with SC, exclusively in the PSC group: one patient died from colorectal cancer, one patient underwent liver transplantation and two patients, in whom severe bile duct stenosis was present at diagnosis, were endoscopically treated for acute cholangitis. Furthermore, two other children with ASC and 2 children with PSC had elevated aminotransferase levels. The 10-year overall survival was 95.8% in all patients, 100% in patients without complicated liver disease, and 75.0% in patients with complications. CONCLUSION In children, ASC is a frequent type of SC, whose prognosis may be better than that in patients with PSC.

Abstract
Hepatic involvement is often encountered in gastrointestinal (GI) diseases, in part because of the close anatomic and physiologic relations between the liver and GI tract. Drainage of the mesenteric blood supply to the portal vein permits absorbed and/or translocated nutrients, toxins, bacterial elements, cytokines, and immunocytes to gain hepatic access. Liver problems in digestive disorders may range from nonspecific hepatocellular enzyme elevations to significant pathologic processes that may progress to end-stage liver disease. Hepatobiliary manifestations of primary GI diseases in childhood and adolescence are not uncommon and include several well-described associations, such as sclerosing cholangitis with inflammatory bowel disease. Liver damage may also result from the effects of drugs used to treat GI diseases, for example, the hepatotoxicity of immunomodulatory therapies. This review highlights the important features of the hepatic and biliary abnormalities associated with 3 common pediatric GI conditions: inflammatory bowel disease, celiac disease, and cystic fibrosis.

Abstract
Apoptosis is a prominent feature of liver diseases. Causative factors such as alcohol, viruses, toxic bile acids, fatty acids, drugs, and immune response, can induce apoptotic cell death via membrane receptors and intracellular stress. Apoptotic signaling network, including membrane death receptor-mediated cascade, reactive oxygen species (ROS) generation, endoplasmic reticulum (ER) stress, lysosomal permeabilization, and mitochondrial dysfunction, is intermixed each other, but one mechanism may dominate at a particular stage. Mechanisms of hepatic apoptosis are complicated by multiple signaling pathways. The progression of liver disease is affected by the balance between apoptotic and antiapoptotic capabilities. Therapeutic options of liver injury are impacted by the clear understanding toward mechanisms of hepatic apoptosis.

Abstract
Patients suffering from primary sclerosing cholangitis (PSC) show considerable differences regarding clinical manifestations (i.e. large duct versus small-duct PSC, presence or absence of concomitant inflammatory bowel disease), disease progression, risk for malignancy and response to therapy, raising the question whether PSC may represent a mixed bag of diseases of different aetiologies. The growing list of secondary causes and diseases 'mimicking' or even overlapping with PSC (e.g. IgG4-associated sclerosing cholangitis), which frequently causes problems in clear-cut discrimination from classic PSC and the emerging knowledge about potential disease modifier genes (e.g. variants of CFTR, TGR5 and MDR3) support such a conceptual view. In addition, PSC in children differs significantly from PSC in adults in several aspects resulting in distinct therapeutic concepts. From a clinical perspective, appropriate categorization and careful differential diagnosis are essential for the management of concerned patients. Therefore, the aim of the current review is to summarize current and evolving pathophysiological concepts and to provide up-to-date perspectives including future treatment strategies for PSC.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic condition affecting the extrahepatic and intrahepatic biliary tree. The incidence is seemingly increasing in children as a result of increased use of cholangiographic screening techniques in children with inflammatory bowel disease. The clinical presentation of PSC in childhood is variable and frequently without obvious cholestatic features, and cholangiography is essential for the diagnosis of this disorder. Histologic findings may help to exclude autoimmune sclerosing cholangitis. The underlying pathogenesis remains poorly understood and, as a result, therapeutic agents that halt disease progression and improve prognosis are lacking. PSC treatment is mainly supportive and directed at controlling cholestatic symptoms and preventing complications. Ursodeoxycholic acid is helpful in inducing biochemical improvement; long-term pediatric studies to determine a benefit of this agent in young patients are lacking, although results from adult studies have not been promising. Some agents such as antibiotics are under investigation with some promising results. Liver transplantation is required for children who progress to end-stage liver disease. Prospective multicenter trials in children with PSC are needed.

Abstract
Primary sclerosing cholangitis (PSC) is uncommon in the younger age range and bile duct brushing cytology can present unique challenges. We describe the case of a 17-year-old boy with a new diagnosis of PSC who presented with cholangiocarcinoma. The clinical history, endoscopic features, cytomorphologic findings, and results of UroVysion™ fluorescent in situ hybridization (FISH) on the bile duct brush are described. UroVysion FISH on bile duct brushings is an ancillary study that can improve the diagnostic sensitivity for malignancy, specially in challenging cases where the cytomorphologic or clinical characteristics of the case are not typical. The occurrence of cholangiocarcinoma in young age group with PSC is uncommon, and the utilization of UroVysion FISH has been rarely described.

Abstract
OBJECTIVES Although it is known that extraintestinal manifestations (EIMs) commonly occur in pediatric inflammatory bowel disease (IBD), little research has examined rates of EIMs and their relation to other disease-related factors in this population. The purpose of this study was to determine the rates of EIMs in pediatric IBD and examine correlations with age, sex, diagnosis, disease severity, and distribution. PATIENTS AND METHODS Data were prospectively collected as part of the Pediatric IBD Collaborative Research Group Registry, an observational database enrolling newly diagnosed IBD patients <16 years old since 2002. Rates of EIM (occurring anytime during the period of enrollment) and the aforementioned variables (at baseline) were examined. Patients with indeterminate colitis were excluded from the analysis given the relatively small number of patients. RESULTS One thousand nine patients were enrolled (mean age 11.6 +/- 3.1 years, 57.5% boys, mean follow-up 26.2 +/- 18.2 months). Two hundred eighty-five (28.2%) patients experienced 1 or more EIMs. Eighty-seven percent of EIM occurred within the first year. Increased disease severity at baseline (mild vs moderate/severe) was associated with the occurrence of any EIM (P < 0.001), arthralgia (P = 0.024), aphthous stomatitis (P = 0.001), and erythema nodosum (P = 0.009) for both Crohn disease (CD) and ulcerative colitis (UC) during the period of follow-up. Statistically significant differences in the rates of EIMs between CD and UC were seen for aphthous stomatitis, erythema nodosum, and sclerosing cholangitis. CONCLUSIONS EIMs as defined in this study occur in approximately one quarter of pediatric patients with IBD. Disease type and disease severity were commonly associated with the occurrence of EIMs.

Abstract
BACKGROUND & AIMS Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by inflammation and progressive bile duct fibrosis. There are limited data on pediatric PSC. METHODS We performed a retrospective chart review of 47 pediatric patients with PSC. RESULTS The mean age at diagnosis was 11 +/- 4.9 years. Symptoms occurred before presentation in 81% of patients; inflammatory bowel disease was found in 59% and autoimmune hepatitis (overlap syndrome) in 25% of patients. Magnetic resonance cholangiography revealed both extrahepatic and intrahepatic, isolated intrahepatic, isolated extrahepatic, and no biliary involvement (small-duct PSC) in 40%, 14%, 10%, and 36%, respectively. Advanced fibrosis (stage >II) was present in 65%. Colonoscopy revealed pancolitis, rectal sparing, and normal findings in 24%, 24%, and 18%, respectively. All patients were treated with ursodeoxycholic acid (UDCA); 9 with overlap syndrome also received immunosuppressants. Fifteen patients without overlap syndrome had positive autoimmune markers and responded to UDCA monotherapy. Liver transplantation was performed in 9 patients (3 with overlap syndrome and 2 with small-duct PSC) at a median time of 7 years after diagnosis. The 10-year posttransplant survival rate was 89%. CONCLUSIONS In one of the largest single-center studies of children with PSC, we found that most children with PSC had inflammatory bowel disease or autoimmune overlap and advanced fibrosis at diagnosis. Levels of alanine aminotransferase and gamma-glutamyl transferase were highest in patients with overlap syndrome and lowest in those with small-duct PSC. Levels of serum liver enzymes normalized after therapy with UDCA, including patients with positive autoimmune markers without histologic features of autoimmune hepatitis.

Abstract
OBJECTIVES We aimed at characterizing the clinical presentation and prognosis of cholangiocarcinoma in youth with and without primary sclerosing cholangitis (PSC). METHODS Thirteen patients < or =25 yr of age with cholangiocarcinoma with or without PSC seen at the Mayo Clinic in Rochester, MN from 1980 to 2005 were identified. RESULTS Of the 13 patients with cholangiocarcinoma, 8 had concomitant PSC and 5 did not. PSC was the associated risk factor in 8/13 (61.5%) whereas PSC was present in only 321/2,014 (15.9%) cases with cholangiocarcinoma in patients older than 25 (P < 0.0001) seen in the same period of time. Seven of the eight (88%) patients with cholangiocarcinoma and PSC had IBD and 5 of the 7 (71%) had Crohn's disease. A mean 11 months transplant free survival was observed (range 3-20 months) in cholangiocarcinoma with PSC versus 8 months in cholangiocarcinoma patients without PSC (NS). CONCLUSIONS Cholangiocarcinoma is a rare disorder in young adults and it seems not to exist in children. The youth group of cholangiocarcinoma plus PSC seems to have a higher prevalence of Crohn's disease whereas the prognosis of cholangiocarcinoma in youth seems to be similarly poor as described in older patients with cholangiocarcinoma.

Abstract
OBJECTIVES The epidemiology of primary sclerosing cholangitis (PSC) has been incompletely assessed by population-based studies. We therefore conducted a population-based study to determine: (a) incidence rates of large and small duct PSC in adults and children, (b) the risk of inflammatory bowel disease on developing PSC, and (c) patterns of clinical presentation with the advent of magnetic resonance cholangiopancreatography (MRCP). METHODS All residents of the Calgary Health Region diagnosed with PSC between 2000 and 2005 were identified by medical records, endoscopic, diagnostic imaging, and pathology databases. Demographic and clinical information were obtained. Incidence rates were determined and risks associated with PSC were reported as rate ratios (RR) with 95% confidence intervals (CI). RESULTS Forty-nine PSC patients were identified for an age- and gender-adjusted annual incidence rate of 0.92 cases per 100,000 person-years. The incidence of small duct PSC was 0.15/100,000. In children the incidence rate was 0.23/100,000 compared with 1.11/100,000 in adults. PSC risk was similar in Crohn's disease (CD; RR 220.0, 95% CI 132.4-343.7) and ulcerative colitis (UC; RR 212.4, 95% CI 116.1-356.5). Autoimmune hepatitis overlap was noted in 10% of cases. MRCP diagnosed large duct PSC in one-third of cases. Delay in diagnosis was common (median 8.4 months). A minority had complications at diagnosis: cholangitis (6.1%), pancreatitis (4.1%), and cirrhosis (4.1%). CONCLUSIONS Pediatric cases and small duct PSC are less common than adult large duct PSC. Surprisingly, the risk of developing PSC in UC and CD was similar. Autoimmune hepatitis overlap was noted in a significant minority of cases.

Abstract
Primary sclerosing cholangitis (PSC) is rare in the pediatric population. Little information exists on the progression of the disease in children. This study evaluated the experience with PSC at the Children's Hospital of Philadelphia over the past 20 years, with an emphasis on the histologic features at presentation, during disease progression, and after liver transplantation. We retrospectively reviewed the medical records of patients diagnosed with PSC between 1981 and 2001. Nineteen patients met the inclusion criteria with classic radiographic evidence of PSC. One additional patient with normal biliary imaging was subsequently diagnosed at the time of liver transplantation. The 20 patients with PSC (14 males) ranged in age from 1 month to 15 years at time of presentation. Inflammatory bowel disease was evident in 50% of patients. Initial histology revealed advanced disease (bridging fibrosis or cirrhosis) in 13 patients and an earlier histologic stage in 7 patients. Of the latter, 3 remain stable, 2 required transplantation, and 2 were lost to follow-up. Seven of the 13 patients with advanced disease required orthotopic liver transplantation, and 3 of these subsequently showed recurrence of primary disease in the allograft. Thus, most subjects presented insidiously at an advanced stage that required transplantation. Subjects who presented at an earlier stage progressed or remained stable, but the histologic findings at diagnosis were generally not predictive of disease progression. Recurrence of PSC after transplantation is a significant complication in children.

Abstract
Primary biliary cirrhosis (PBC), autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC) are chronic liver diseases that likely have an autoimmune basis to their pathogenesis. Although significant strides have been made in the clinical management of these conditions, their pathogenesis remains obscure. Understanding of various epidemiological factors may shed light on predisposing or causative factors for these diseases. Most is known about the epidemiology of PBC, with only minimal information on that of PSC and AIH. In this review, the current data on the epidemiology of PBC, AIH and PSC are summarized and suggestions are made for future work in this important area.

Abstract
Primary sclerosing cholangitis (PSC) is increasingly diagnosed in children and adolescents, but its long-term prognosis remains uncertain. The aim of this longitudinal, cohort study was to determine the long-term outcome of children with PSC. Fifty-two children with cholangiography-proven PSC (34 boys and 18 girls; mean age 13.8 +/- 4.2 years; range, 1.5-19.6 years) who were seen at our institution over a 20-year period were followed-up for up to 16.7 years. Two thirds presented with symptoms and/or signs of PSC and 81% had concomitant inflammatory bowel disease (IBD). Twenty-five percent had total alkaline phosphatase activity within the normal range for the age group, but all of them had elevated gamma-glutamyl transpeptidase levels. Autoimmune hepatitis overlapping with PSC was present in 35% of children. A positive but transient clinical and/or biochemical response occurred under therapy with ursodeoxycholic acid, alone or in combination with immunosuppressive medications. During follow-up, 11 children underwent liver transplantation for end-stage PSC and 1 child died. The median (50%) survival free of liver transplantation was 12.7 years. Compared with an age- and gender-matched U.S. population, survival was significantly shorter in children with PSC (P <.001). In a Cox regression model, lower platelet count, splenomegaly, and older age were associated with shorter survival. Presence of autoimmune hepatitis overlapping with PSC (P =.2) or medical therapy (P =.2) did not affect survival. In conclusion, PSC significantly decreases survival in this child population. Although pharmacologic therapy may improve symptoms and liver test results initially, it does not seem to impact the long-term outcome.

Abstract
Primary sclerosing cholangitis is a chronic cholestatic liver disease of unknown etiology. Immunogenetic factors are considered important in its pathogenesis. The genetic susceptibility to primary sclerosing cholangitis is associated, in part, with the HLA HLA-DRB1, DQA1, DQB1 haplotype. Liver histology in primary sclerosing cholangitis is characterized by a portal inflammatory infiltrate mostly composed of memory T cells. Many patients eventually will develop cholangiocarcinoma, and inactivation of the p16 tumor-suppressor gene might be involved in neoplastic transformation. Alcohol consumption might be a risk factor for cholangiocarcinoma, and, in some patients, elevation of serum CA19-9 marks the neoplastic transformation. To date, no medical treatment has been proven effective. Endoscopic therapy might be useful in some patients, but controlled studies are lacking. Liver transplantation remains the only effective treatment. Posttransplant survival and quality of life are continuously improving despite the fact that the disease may recur in some patients after transplantation. Nevertheless, patient selection and timing of indication for liver transplantation remain uncertain.

Abstract
The purpose of this review is to highlight new developments during the past year regarding diagnosis and clinical features of inflammatory bowel disease. Endoscopy remains the cornerstone for diagnosis and evaluation of ileocolonic inflammatory bowel disease. In ulcerative colitis, recent studies have challenged the concept of a continuous and homogeneous inflammatory process with constant rectal involvement: patchy inflammation and rectal sparing were reported in treated ulcerative colitis, and frequent cecum and appendiceal orifice skip lesions were confirmed. Cross-sectional imaging techniques usefully complement endoscopy by assessing whole-bowel thickness and detecting abscesses and fistulae. Furthermore, echo Doppler ultrasound is able to measure mesenteric blood flow, which is increased in active inflammatory bowel disease and seems to parallel inflammatory disease activity. Osteopenia, which affects approximately half of patients with inflammatory bowel disease, can be detected by dual-energy x-ray absorptiometry and prevented. Hyperhomocysteinemia, a predisposing factor for thrombosis, seems to be more frequent in inflammatory bowel disease, and can be corrected by folate supplementation. The concept of an aggressive, penetrating form of Crohn disease with early postoperative recurrence as opposed to a more indolent, nonpenetrating form of the disease, with later recurrence, was recently challenged. The most significant predictor of the risk of malignancy in inflammatory bowel disease remains the presence of dysplasia in colonic biopsy specimens. A dysplastic polypoid lesion or mass is a strong predictor of cancer but should be distinguished from the dysplasia inherent in a coincident sporadic adenoma.
