IgG4-related disease is a newly recognized fibro-inflammatory condition characterized by several features: a tendency to form tumefactive lesions in multiple sites; a characteristic histopathological appearance; and-often but not always-elevated serum IgG4 concentrations. An international symposium on IgG4-related disease was held in Boston, MA, on 4-7(More)
Autoimmune pancreatitis (AIP) is a peculiar type of pancreatitis of presumed autoimmune etiology. Many new clinical aspects of AIP have been clarified during the past 10 years, and AIP has become a distinct entity recognized worldwide. However, its precise pathogenesis or pathophysiology remains unclear. As AIP dramatically responds to steroid therapy,(More)
atic duct and diffuse enlargement of the entire pancreas due to lymphocyte infiltration. In 1995, Japanese investigators 3 firstly proposed a concept of " autoimmune pancreatitis (AIP) " , in which the patients showed diffusely enlarged pancreas, narrowing pancreatogram, increased serum IgG, presence of autoantibodies, fibrotic changes with lymphocytic(More)
1 OBJECTIVE—The pathogenesis of autoimmune pancreatitis (AIP) and fulminant type 1 diabetes remains unclear, although it is known that immune-mediated processes severely compromise the endocrine and exocrine functions in both diseases. RESEARCH DESIGN AND METHODS—We have screened a ␭TriplEx2 human pancreas cDNA library with serum from a patient with AIP and(More)
OBJECTIVE Autoimmune pancreatitis (AIP) is a treatable form of chronic pancreatitis that has been increasingly recognised over the last decade. We set out to better understand the current burden of AIP at several academic institutions diagnosed using the International Consensus Diagnostic Criteria, and to describe long-term outcomes, including organs(More)
We investigated the aetiological role of group A rotavirus in adults with acute diarrhoea in a 4-year prospective study. Of 683 patients with acute diarrhoea, 97 (14%) shed rotavirus as a sole agent, whereas six (5%) of 115 patients without diarrhoea shed rotavirus. Half of patients with rotavirus diarrhoea required admission to hospital. Unlike rotavirus(More)
Juxtapapillary duodenal diverticula (JPD) are observed in around 10-20% of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). They are acquired extraluminal outpouchings of the duodenal wall through 'locus minoris resistance' and their incidence increases with age. They have been studied mainly with regard to their association with(More)
BACKGROUND/AIMS The objective of this study was to compare the clinical characteristics of patients with autoimmune pancreatitis (AIP) with or without Mikulicz's disease (MD) and with MD alone. METHODS We investigated the clinical findings in 15 AIP patients with MD (group A+M), 49 AIP only patients (group A), and 14 MD only patients (group M). RESULTS(More)
IgG4-related disease (IgG4-RD) is a potentially multiorgan disorder. In this study, clinical and serological features from 132 IgG4-RD patients were compared about organ correlations. Underlying pathologies comprised autoimmune pancreatitis (AIP) in 85 cases, IgG4-related sclerosing cholangitis (IgG4-SC) in 12, IgG4-related sialadenitis (IgG4-SIA) in 56,(More)
It is now clear that are two histological types (Type-1 and Type-2) of autoimmune pancreatitis (AIP). The histological pattern of Type-1 AIP, or traditional AIP, is called lymphoplasmacytic sclerosing pancreatitis (LPSP). The histological pattern of Type-2 AIP is characterized by neutrophilic infiltration in the epithelium of the pancreatic duct. In(More)
