Autoimmune cholangitis is a clinical constellation of chronic cholestasis, histological changes of chronic nonsuppurative cholangitis and the presence of autoantibodies other than antimitochondrial antibody (AMA). It is uncertain whether this entity is definitely different from AMA positive primary biliary cirrhosis (PBC), though it shows some differences. We report a case of autoimmune cholangitis in a 59-year-old woman, who had been previously diagnosed as AMA-positive PBC associated with rheumatoid arthritis, has been converted to an AMA-negative and anticentromere antibody-positive PBC during follow-up. The response to ursodeoxycholic acid treatment is poor except within the first few months, but prednisolone was dropping the biochemical laboratory data.

Immunoglobulin G4-related systemic disease (IgG4-RSD) is a recently defined emerging entity characterized by a diffuse or mass forming inflammatory reaction rich in IgG4-positive plasma cells associated with fibrosclerosis and obliterative phlebitis. IgG4-RSD usually affects middle aged and elderly patients, with a male predominance. It is associated with an elevated serum titer of IgG4, which acts as a marker for this recently characterized entity. The prototype is IgG4-related sclerosing pancreatitis or autoimmune pancreatitis (AIP). Other common sites of involvement are the hepatobiliary tract, salivary gland, orbit, and lymph node, however practically any organ can be involved, including upper aerodigestive tract, lung, aorta, mediastinum, retroperitoneum, soft tissue, skin, central nervous system, breast, kidney, and prostate. Fever or constitutional symptoms usually do not comprise part of the clinical picture. Laboratory findings detected include raised serum globulin, IgG and IgG4. An association with autoantibody detection (such as antinuclear antibodies and rheumatoid factor) is seen in some cases. Steroid therapy comprises the mainstay of treatment. Disease progression with involvement of multiple organ-sites may be encountered in a subset of cases and may follow a relapsing-remitting course. The principal histopathologic findings in several extranodal sites include lymphoplasmacytic infiltration, lymphoid follicle formation, sclerosis and obliterative phlebitis, along with atrophy and destruction of tissues. Immunohistochemical staining shows increased IgG4+ cells in the involved tissues (>50 per high-power field, with IgG4/IgG ratio >40%). IgG4-RSD may potentially be rarely associated with the development of lymphoma and carcinoma. However, the nature and pathogenesis of IgG4-RSD are yet to be fully elucidated and provide immense scope for further studies.

Recent studies have proposed nomenclatures of type 1 autoimmune pancreatitis (AIP) (IgG4-related pancreatitis), IgG4-related sclerosing cholangitis (IgG4-SC), IgG4-related cholecystitis, and IgG4-related hepatopathy as IgG4-related disease (IgG4-RD) in the hepato-bilio-pancreatic system. In IgG4-related hepatopathy, a novel concept of IgG4-related autoimmune hepatitis (AIH) with the same histopathological features as AIH has been proposed. Among organs involved in IgG4-RD, associations with pancreatic and biliary lesions are most frequently observed, supporting the novel concept of "biliary diseases with pancreatic counterparts." Targets of type 1 AIP and IgG4-SC may be periductal glands around the bile and pancreatic ducts. Based on genetic backgrounds, innate and acquired immunity, Th2-dominant immune status, regulatory T (Treg) or B cells, and complement activation via a classical pathway may be involved in the development of IgG4-RD. Although the role of IgG4 remains unclear in IgG4-RD, IgG4-production is upregulated by interleukin 10 from Treg cells and by B cell activating factor from monocytes/basophils with stimulation of toll-like receptors/nucleotide-binding oligomerization domain-like receptors. Based on these findings, we have proposed a hypothesis for the development of IgG4-RD in the hepato-bilio-pancreatic system. Further studies are necessary to clarify the pathogenic mechanism of IgG4-RD.

OBJECTIVETo investigate the positive rate of auto antibodies and autoimmune liver diseases in patients with abnormal liver function and it's clinical significance.
METHODS511 sera with abnormal ALT (>40 U/L) were continuously collected, all the sera were examined for antibodies and clinical information of 469 cases were studied.
RESULTSAmong the 511 sera, 14.09% of them showed of ANA positive, 0.59% of SMA positive, 2.94% of AMA positive, 0.98% of AMA-M2 positive, 0.59% of SS-A positive, 0.19% of SS-B positive, 0.19% of JO-1 and 0.78% of dsDNA positive and all SLA/LP, LC-1 and LKM-1 and ANA profile were negative. Clinical information was analyzed on 469 cases which have complete data from the 511 patients. Of these 469 cases, 5 cases (1.06%) were found to be PBC, 2 case (0.43%) were AIH, no PSC was found, 77.78% patients among those with positive auto antibodies were diagnosed as viral hepatitis and there were 18.29% patients with viral hepatitis showed different auto antibodies.
CONCLUSIONThe high titer auto antibodies were important criterion for diagnosis of autoimmune liver diseases. The positive rate of autoantibodies of autoimmune liver diseases was similar to hepatitis C and E

Sclerosing cholangitis is a spectrum of chronic progressive cholestatic liver disease characterized by inflammation, fibrosis, and stricture of the bile ducts, which can be classified as primary and secondary sclerosing cholangitis. Primary sclerosing cholangitis is a chronic progressive liver disease of unknown cause. On the other hand, secondary sclerosing cholangitis has identifiable causes that include immunoglobulin G4-related sclerosing disease, recurrent pyogenic cholangitis, ischemic cholangitis, acquired immunodeficiency syndrome-related cholangitis, and eosinophilic cholangitis. In this review, we suggest a systemic approach to the differential diagnosis of sclerosing cholangitis based on the clinical and laboratory findings, as well as the typical imaging features on computed tomography and magnetic resonance (MR) imaging with MR cholangiography. Familiarity with various etiologies of sclerosing cholangitis and awareness of their typical clinical and imaging findings are essential for an accurate diagnosis and appropriate management.

BACKGOUND/AIMS: The involvement of bile ducts is frequently reported in autoimmune pancreatitis (AIP), which seem to have similar features to primary sclerosing cholangitis (PSC). Recent systematic comparative studies about these diseases are rare in Korea. METHODS: We retrospectively analyzed 26 patients with AIP with bile duct involvement and 30 patients with classic PSC who were diagnosed during the last decade. RESULTS: The mean age of patients was significantly higher in AIP than PSC at the time of diagnosis. There was a preponderance of men in both group, which was more prominent in AIP. The most common symptom in patients with AIP was jaundice, but PSC patients usually visited hospitals due to incidentally detected abnormal liver function tests. Most (26/31) of AIP had bile duct involvement. All of these patients showed narrowing of intrapancreatic common bile ducts and one patient exhibited hilar involvement as well. About 80% of PSC had both intra- and extrahepatic ducts involvement, and the characteristic features involve multifocal strictures. AIP patients showed improvement with steroid treatment, however, most PSC patients showed clinical deterioration. CONCLUSIONS: The clinical and cholangiographic findings of patients with AIP and PSC have many different characteristics. Therefore, further study of two diseases is required for the proper diagnosis and management.
