OBJECTIVE: To describe the characteristics and clinical course of children and young persons with inflammatory bowel disease (IBD) and sclerosing cholangitis (SC). STUDY DESIGN: Retrospective analysis of clinical characteristics, management, and outcome of two separate cohorts of children and young persons with IBD-SC managed in a tertiary pediatric gastroenterology center and in a tertiary pediatric hepatology center in the UK. RESULTS: Eighty-two pediatric patients (31% female) with IBD-SC and a mean age at diagnosis of 11.9 ± 2.8 years were followed up for a mean of 6.8 ± 3.3 years. The most common type of IBD was ulcerative colitis (55%), followed by unclassified IBD (30%) and Crohn's disease (15%). Autoimmune SC (ASC) was diagnosed in 72%, and small duct SC was diagnosed in 28%. Complication-free and native liver survival were 96% and 100%, respectively, at 5 years after diagnosis and 75% and 88%, respectively, at 10 years after diagnosis. Patients in the gastroenterology center, who were diagnosed with liver disease sooner after diagnosis of IBD compared with the hepatology center cohort (mean, 2.7 ± 6.1 months vs 9.3 ± 19.4 months; P = .03), did not develop liver-related complications during follow-up. CONCLUSIONS: Our data suggest that children with IBD-SC have better clinical outcomes than have been reported previously, particularly if diagnosed early. We recommend prompt assessment for SC, including liver biopsy and biliary imaging, when liver function abnormalities are detected in a children diagnosed with IBD.

OBJECTIVES: To report baseline features and long-term medical/social outcomes of juvenile autoimmune liver disease, including autoimmune hepatitis (AIH) and autoimmune sclerosing cholangitis (ASC), managed in a single tertiary center. STUDY DESIGN: Retrospective study of children diagnosed in 2000-2004 with AIH/ASC followed up to date. Patients with abnormal cholangiogram were classified as ASC. Presentation and outcome features were compared. RESULTS: Eighty-three children were included (42 female, median age 12.1 years [8.5-14.1 years], AIH = 54, ASC = 29). Most (65%) had antinuclear and/or anti-smooth muscle autoantibodies; 6% presented with acute liver failure; 29% had histologic evidence of cirrhosis. The 1999 and simplified International Autoimmune Hepatitis Group criteria failed to diagnose up to 26% of patients with AIH and 48% with ASC, and the proposed the European Society for Pediatric Gastroenterology, Hepatology and Nutrition criteria were accurate. Response to treatment was excellent with 95% achieving normal transaminase levels. During follow-up, 31% had at least 1 relapse episode; 3 patients with AIH developed cholangiopathy and 5 patients with ASC developed progressive bile duct injury. At last follow-up (median of 14.5 years, 10.4-16.8), 99% were alive, 11 underwent transplantation and 1 is listed for transplant. Five-, 10-, and 15-year transplant-free survival rates were 95%, 88%, and 83%; patients with ASC and those relapsing being more likely to require transplant. Social outcome was excellent with 93% in employment/education. CONCLUSIONS: Seamless management of juvenile autoimmune liver disease leads to excellent clinical and social outcomes. Despite good response to immunosuppressive treatment, patients with ASC have a worse prognosis than those with AIH. Diagnostic models developed for adults are unsatisfactory to correctly diagnose juvenile autoimmune liver disease.

OBJECTIVE: To assess the incidence, clinical features, and outcome of autoimmune liver disease (AILD) in patients with sickle cell disease (SCD). STUDY DESIGN: Single center retrospective review of patients with SCD with AILD referred between 1999 and 2015. RESULTS: Thirteen of 77 (17%) patients with SCD with hepatic dysfunction were diagnosed with AILD (median age 11, range, 3.4-16 years) with a female preponderance (77%). Acute hepatitis and insidious onset were the commonest presentations. Two patients (15%) presented with acute liver failure. In 2 patients (15%), parvovirus B19-induced transient red cell aplasia preceded the diagnosis of AILD. All patients were positive for antinuclear and/or smooth muscle autoantibodies. Six of 12 patients (50%) had cholangiopathy on cholangiogram suggesting autoimmune sclerosing cholangitis (ASC). Liver biopsy, performed in 11 patients without complications, showed interface hepatitis in 90%. Patients with AILD were treated with standard immunosuppression. After a median follow-up of 3.8 years (range, 0.2-14.3), 10 patients are alive (1 was transplanted 6.4 years after diagnosis); 2 are lost to follow-up; 1 died of subdural hemorrhage before starting treatment for AILD. Five (42%) achieved full and 4 (33%) partial biochemical remission. Ulcerative colitis, present in 4 patients (2 male patients, 3 with ASC) was diagnosed in 2 patients before and in 2 patients after the diagnosis of AILD. CONCLUSIONS: AILD is not uncommon in patients with SCD, affecting mainly female patients and responding satisfactorily to immunosuppressive treatment. Liver biopsy is helpful in confirming the diagnosis and can be safely performed in the absence of acute vaso-occlusive sickling episodes. Ulcerative colitis is common in the presence of ASC.
