autoimmune cholangiopathy

Sophie Restellini, Olivier Chazouillères, Jean-Louis Frossard
Inflammatory bowel diseases (IBD) are associated with various hepatobiliary disorders, reported both in Crohn's disease (CD) and ulcerative colitis (UC). They may occur at any moment in the natural course of the disease. The prevalence of liver dysfunction rises from 3% to 50% accordingly to definitions. Fatty liver is considered as the most common hepatobiliary complication in IBD whilst primary sclerosing cholangitis (PSC) the most specific one. Less frequently, IBD-associated hepatobiliary disorders include: autoimmune hepatitis/PSC overlap syndrome, IgG4-associated cholangiopathy, primary biliary cholangitis (PBC), hepatic amyloidosis, granulomatous hepatitis, cholelithiasis, portal vein thrombosis, and liver abscess...

Various cellular responses including apoptosis, necrosis, autophagy and cellular senescence are involved in the pathogenesis of inflammatory cholangiopathies, such as primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) and biliary atresia (BA). For example, dysregulated autophagy may play a role in abnormal expression of mitochondrial antigens and following autoimmune pathogenesis in bile duct lesions in PBC. Recently, new types of regulated cell death including necroptosis, parthanatos, pyroptosis, immunogenic cell death are the subject of numerous reports and they may play roles in pathogenesis of liver diseases, such as nonalcoholic steatohepatitis...

BACKGROUND: Immunoglobulin G4 (IgG4)-associated diseases mostly involve the pancreaticobiliary tree and pancreatic parenchyma. This disease complex is characterized by marked response to corticosteroid therapy and response to steroids is incorporated in the diagnostic algorithm of IgG4 associated diseases. However, there is much unknown about the sequences and duration of healing during the corticosteroid therapy in the literature. CASE REPORT: In this case report, we report a young male patient with IgG4 associated extrahepatic biliary stricture and autoimmune pancreatitis successfully treated with corticosteroids...

Liver biopsy is recommended to establish the diagnosis and to assess remission in autoimmune hepatitis (AIH) patients. The aim of our study was to assess the utility of repeat biopsy in AIH. Forty liver biopsies from 20 consecutive AIH patients who underwent repeat biopsy were evaluated. We assessed the biopsies for histological findings other than AIH and how often the repeat biopsy led to a change in clinical management. Furthermore, we correlated the changes in the laboratory findings with the histological features...

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...

Autoimmune pancreatitis (AIP) is part of a systemic fibrosclerotic process characterized by lymphoplasmacytic infiltrate with immunoglobulin G subtype-4 (IgG4) positive cells. It characteristically presents with biliary obstruction due to mass-like swelling of the pancreas. Frequently AIP is accompanied by extra-pancreatic manifestations including retroperitoneal fibrosis, thyroid disease, and salivary gland involvement. Auto-antibodies, hypergammaglobulemia, and prompt resolution of pancreatic and extrapancreatic findings with steroids signify its autoimmune nature...

OBJECTIVE: To determine the diagnostic performance of imaging criteria for distinguishing Ig-G4-associated autoimmune cholangiopathy (IAC) from primary sclerosing cholangitis (PSC) and bile duct malignancy. METHODS: A medical records search between January 2008 and October 2013 identified 10 patients (8 M, 2 F, mean age 61 years, range 34-82) with a clinical diagnosis of IAC. Fifteen cases of PSC (6 M, 9 F, mean age 50, range 22-65) and 15 cases of biliary malignancy (7 M, 8 F, mean age 65, range 48-84) were randomly selected for comparative analysis...

Biliary atresia (BA) is the most frequent identifiable cause of neonatal cholestasis and the majority of patients will need liver transplantation for survival. Despite surgical intervention with the Kasai portoenterostomy, significant fibrosis and cirrhosis develops early in life. An increased understanding of what causes this inflammatory fibrosing cholangiopathy will lead to therapies aimed at protecting the intrahepatic biliary system from immune-mediated damage. This review focuses on studies pertaining to the role of the adaptive immune response in bile duct injury in BA, including cellular and humoral immunity...

PURPOSE OF REVIEW: The clinical spectrum of immunoglobulin G4-related disease (IgG4-RD) is diverse and the disease may affect multiple organ systems. The pancreatobiliary tract probably is the clinically most important localization of the disease but diagnosing IgG4-related cholangiopathy (synonym: IgG4-associated cholangitis) or autoimmune pancreatitis is often challenging. This review summarizes the current best practice in diagnosing and treating IgG4-related cholangiopathy and recent advances in our understanding of its cause...

Fibrosing cholangiopathy such as primary sclerosing cholangitis (PSC) and biliary atresia (BA) is characterized by biliary epithelial injuries and concentric fibrous obliteration of the biliary tree together with inflammatory cell infiltration. In these diseases, inappropriate innate immunity is reported to contribute more to bile duct pathology as compared with various aspects of "classical" autoimmune diseases. Primary biliary cirrhosis (PBC) is characterized by chronic cholangitis with bile duct loss and classical autoimmune features...

Autoimmune cholangitis (AIC) or autoimmune cholangiopathy is a chronic inflammation of liver and a variant syndrome of autoimmune hepatitis (AIH). We present a case of an adult female who had biochemical features of cholestasis and transaminasemia but aminotransferases were not in the hepatitis range and had histological evidence of bile duct injury which was subsequently diagnosed as autoimmune cholangitis.

IgG4 related cholangiopathy, a distinctive type of cholangitis of unknown origin, is characterized by increased serum levels of IgG4, massive infiltration of IgG4-positive plasma cells with storiform fibrosis and/or obliterative phlebitis in the thickened bile duct wall, and good response to steroids. Patients with IgG4-cholangiopathy are frequently associated with autoimmune pancreatitis; IgG4-cholangiopathy is recognized as a biliary manifestation of IgG4-related disease. This condition can be diagnosed by a combination of imaging, serology, histopathology, and steroid responsiveness; however, cholangiographic features are often difficult to differentiate from primary sclerosing cholangitis, pancreatic cancer, or cholangiocarcinoma...

Recently, autoimmune pancreatitis, a pancreatic manifestation of IgG4-related disease (IgG4-RD) has been recognized as a novel clinical entity associated with massive infiltration of IgG4-positive cells. The first international symposium on IgG4-RD endorsed the comprehensive nomenclature as IgG4-RD, which the Japanese research committee supported by the Ministry of Health, Labor and Welfare of Japan proposed in 2009, and proposed the individual nomenclatures for each organ system manifestations and the international pathologic consensus in 2011...

A 63-year-old man presented with the initial diagnosis of autoimmune pancreatitis with obstructive jaundice. CT of the abdomen revealed an oedematous pancreas and dilated common bile duct (CBD), without gallstones. After failure of initial retrograde cholangiopancreatography, a percutaneous biliary catheter was inserted with good drainage. Subsequent endoscopic retrograde cholangiopancreatography (ERCP) revealed a 2 cm distal CBD stricture. A biliary stent was inserted past the stricture. Biopsy of the stricture, brush cytology of the bile duct and fine needle aspiration of pancreatic head under endoscopic ultrasound guidance were negative for malignancy...

Abnormal liver biochemical tests are present in up to 30% of patients with inflammatory bowel disease (IBD), and therefore become a diagnostic challenge. Liver and biliary tract diseases are common extraintestinal manifestations for both Crohn's disease and ulcerative colitis (UC), and typically do not correlate with intestinal activity. Primary sclerosing cholangitis (PSC) is the most common hepatobiliary manifestation of IBD, and is more prevalent in UC. Approximately 5% of patients with UC develop PSC, with the prevalence reaching up to 90%...

Autoimmune liver disease spans three predominant processes, from the interface hepatitis of autoimmune hepatitis to the lymphocytic cholangitis of primary biliary cirrhosis, and finally the obstructive fibrosing sclerotic cholangiopathy of primary sclerosing cholangitis. Although all autoimmune in origin, they differ in their epidemiology, presentation and response to immunosuppressive therapy and bile acid based treatments. With an ongoing better appreciation of disease aetiology and pathogenesis, treatment is set ultimately to become more rational...

Secondary sclerosing cholangitis (SSC) is an aggressive and rare disease with intricate pathogenesis and multiple causes. Understanding the specific cause underlying each case of SSC is crucial in the clinical management of the disease. Radiologic imaging can help diagnose SSC and hence institute management in a timely manner. Management may encompass simple interventions, such as supportive therapy, antibiotics, and monitoring, or more serious measures, such as surgery, endoscopic intervention, or liver transplantation...

Biliary atresia (BA) is an infantile obstructive cholangiopathy of unknown etiology with suboptimal therapy, which is responsible for 40 to 50% of all pediatric liver transplants. Although the etiology of bile duct injury in BA in unknown, it is postulated that a pre- or perinatal viral infection initiates cholangiocyte apoptosis and release of antigens that trigger a Th1 immune response that leads to further bile duct injury, inflammation, and obstructive fibrosis. Humoral immunity and activation of the innate immune system may also play key roles in this process...

Primary biliary cirrhosis (PBC) is histologically characterized by chronic nonsuppurative destructive cholangitis (CNSDC) associated with destruction of small bile ducts. The pathogenesis of PBC, predominance of female, or the reason why biliary duct is selectively involved, however, remains unknown. Infectious or non-infectious noxious insults such as xenobiotic chemicals may precipitate in the individual having a genetic background of PBC. Activation of innate immune response seems to be a key event in early PBC, leading to the autoimmune injury of small intrahepatic bile duct...
