      BACKGROUND: Sclerosing pancreatitis is a unique form of pancreatitis that is characterized by irregular narrowing of the main pancreatic duct, lymphoplasmacytic inflammation of the pancreas, and hypergammaglobulinemia and that responds to glucocorticoid treatment. Preliminary studies suggested that serum IgG4 concentrations are elevated in this disease but not in other diseases of the pancreas or biliary tract.

      METHODS: We measured serum IgG4 concentrations using single radial ...

      OBJECTIVE: To establish an appropriate steroid treatment regimen for autoimmune pancreatitis (AIP).

      METHODS: A retrospective survey of AIP treatment was conducted in 17 centres in Japan. The main outcome measures were rate of remission and relapse.

      RESULTS: Of 563 patients with AIP, 459 (82%) received steroid treatment. The remission rate of steroid-treated AIP was 98%, which was significantly higher than that of patients without steroid treatment (74%, 77/104; p<0.001). Steroid ...

      BackgroundFluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) has been widely used for the diagnosis of pancreatic cancer. Because autoimmune pancreatitis is easily misdiagnosed as pancreatic cancer and can be tested for by FDG-PET analysis based on the presence of suspected pancreatic cancer, we attempted to clarify the differences in FDG-PET findings between the two conditions.MethodsWe compared FDG-PET findings between 15 patients with autoimmune pancreatitis and 26 ...

      BackgroundAutoimmune pancreatitis is a unique form of chronic pancreatitis characterized by high serum IgG4 concentrations and abundant IgG4-bearing plasma cell infiltration in the pancreatic lesion, and it has been reported to be associated with a variety of extrapancreatic lesions, leading us to postulate the concept of a systemic inflammatory disease. To confirm this, we clarified the exact distribution of these extrapancreatic lesions and provide a panoramic view of them.MethodsThe ...

      BACKGROUND & AIMS: Autoimmune pancreatitis is a distinctive disease entity characterized by high serum immunoglobulin G4 concentrations. Because of the close association between some autoimmune diseases and particular alleles of major histocompatibility complex genes, we investigated the association between HLA alleles and autoimmune pancreatitis.

      METHODS: HLA-A, -B, -C, -DR, and -DQ gene typing and HLA-DRB1, -DQB1, and -DPB1 allele typing were performed by the polymerase chain reaction ...

      Autoimmune pancreatitis (AIP) is characterized by high serum immunoglobin (Ig) G4 concentrations, lymphoplasmacytic inflammation, and a favorable response to corticosteroid treatment. Since liver dysfunction is frequently seen in AIP patients, we investigated hepatic histopathology and its clinical significance in patients with AIP. We examined the clinical features, histology, and immunoglobin G (IgG)4-bearing plasma cell infiltration of liver biopsies from 17 patients with AIP and 63 ...

      BACKGROUND: A wide variety of systemic lesions have been seen in patients with autoimmune pancreatitis. The pulmonary involvement of autoimmune pancreatitis was analysed to clarify the clinicopathological features of pulmonary lesions in comparison with pulmonary sarcoidosis.

      MATERIALS AND METHODS: Nineteen patients had autoimmune pancreatitis and eight had pulmonary sarcoidosis. The symptoms, laboratory data, chest computed tomography, Gallium-67 scintigraphy, pulmonary function testing ...

      Autoimmune pancreatitis (AIP) is a recently proposed disease entity, in which an elevated serum IgG4 is characteristic. This disease is sometimes associated with other inflammatory diseases: Sjögren's disease, or sclerosing cholangitis. The aim of the present paper was to examine the difference in pathophysiology between AIP-associated sclerosing cholangitis (AIP-SC) and primary sclerosing cholangitis (PSC). The clinicopathological findings and the immunohistochemical expressions of IgG ...

      BACKGROUND AND AIM: IgG4-related sclerosing cholangitis (IgG4-SC) must be precisely distinguished from primary sclerosing cholangitis and cholangiocarcinoma (CC) because the treatments are completely different. However, the pathological diagnosis of IgG4-SC is difficult. Therefore, highly specific non-invasive criteria such as serum IgG4 should be established. This study established a cut-off for serum IgG4 to differentiate IgG4-SC from respective controls using serum IgG4 levels ...

      OBJECTIVES: Autoimmune pancreatitis (AIP) is characterized by high serum IgG4 concentrations, lymphoplasmacytic inflammation, and a favorable response to corticosteroid treatment. Although the HLA DRB1*0405-DQB1*0401 haplotype and Fc receptor-like 3 polymorphisms have been associated with AIP, the role of other genetic factors is largely unknown. As cytotoxic T-lymphocyte antigen 4 (CTLA4) polymorphisms have recently been linked with several autoimmune diseases, we sought to determine if ...

      BackgroundIgG4-related disease (IgG4-RD) is a novel clinical disease entity characterized by elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4+ plasma cells. Although IgG4-RD is not rare and is clinically important, its clinical diagnostic criteria have not been established. Comprehensive diagnostic criteria for IgG4-RD, including the involvement of various organs, are intended for the practical use of general physicians and nonspecialists.MethodsTwo ...

      OBJECTIVE: Corticosteroid has been established as the standard therapy for autoimmune pancreatitis (AIP), but the requirement for maintenance corticosteroid therapy is controversial. We conducted a randomised controlled trial to clarify the efficacy of maintenance corticosteroid therapy in patients with AIP.

      DESIGN: We conducted a multicentre, tertiary setting, randomised controlled trial. After the induction of remission with the initial oral prednisolone (PSL) treatment, maintenance ...

      We have previously reported that autoimmune pancreatitis (AIP) is a bioclinical entity characterized by high serum immunoglobulin G4 concentrations and association with the HLA-DRB1*0405-DQB1*0401 haplotype. However, the precise identity of gene(s) within this haplotype directly responsible for AIP pathogenesis is yet to be established. To dissect the genetic contribution of the incriminated haplotype, we have now performed an association analysis within the human leukocyte antigen (HLA) ...

      BACKGROUND: There are no descriptions of the appearance of the main duodenal papilla in sclerosing pancreatitis. The intent of the present study was to clarify the characteristics of the main duodenal papilla in patients with sclerosing pancreatitis.

      METHODS: Macroscopic findings at ERCP with reference to the main duodenal papilla of 17 patients with sclerosing pancreatitis were compared with those of 24 patients with normal ERCP findings, 11 with chronic pancreatitis, 13 with primary ...

      PURPOSE: Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by a variety of extra-pancreatic involvements which are frequently misdiagnosed as lesions of corresponding organs. The purpose of this study was to clarify the diagnostic imaging features of extra-pancreatic lesions associated with autoimmune pancreatitis.

      MATERIALS AND METHODS: We retrospectively analyzed diagnostic images of 90 patients with autoimmune pancreatitis who underwent computer-assisted ...
