A 26-year-old Japanese woman presented with adrenal insufficiency, and treatment was started with cortisone and fludrocortisone in 1975. A few years later, she presented with hypoparathyroidism and was diagnosed with autoimmune polyendocrine syndrome type I (APS I), and treatment with calcium and alfacalcidol was started. She was found to have subacute thyroiditis and relative adrenal failure in 2006. Her condition remained stable under treatment with cortisone, fludrocortisone, levothyroxine, calcium lactate, precipitated calcium carbonate and alfacalcidol...

It is well known that the most important etiologies of acute pancreatitis are gallstones and alcohol consumption. Once these causes have been ruled out, especially in young adults, it is important to consider less frequent etiologic factors such as drugs, trauma, malformations, autoimmunity or systemic diseases. Other rare and less well studied causes of this pathology are infections, among which Mycoplasma pneumoniae has been reported to cause acute pancreatitis as an unusual extrapulmonary manifestation. Here, we report the case of a 21-year-old patient who had acute idiopathic pancreatitis associated with an upper respiratory tract infection...

MicroRNAs (miRNAs) are a series of conserved, short, non-coding RNAs that modulate gene expression in a posttranscriptional manner. miRNAs are involved in almost every physiological and pathological process. Type 1 diabetes (T1D) is an autoimmune disease that is the result of selective destruction of pancreatic β-cells driven by the immune system. miRNAs are also important participants in T1D pathogenesis. Herein, we review the most recent data on the potential involvement of miRNAs in T1D. Specifically, we focus on two aspects: the roles of miRNAs in maintaining immune homeostasis and regulating β-cell survival and/or functions in T1D...

Type 1 diabetes (T1D) is an autoimmune proinflammatory disease with no effective intervention. A major obstacle in developing new immunotherapies for T1D is the lack of means for monitoring immune responsiveness to experimental therapies. The LEW1.WR1 rat develops autoimmunity following infection with the parvovirus Kilham rat virus (KRV) via mechanisms linked with activation of proinflammatory pathways and alterations in the gut bacterial composition. We used this animal to test the hypothesis that intervention with agents that block innate immunity and diabetes is associated with a shift in the gut microbiota...

A 10-year-old child presented with prolonged fever, lymphadenopathy, weight loss, oral ulcers, alopecia and parotitis. She later developed arterial thrombosis, poly-serositis, nephritis, myocarditis, sacro-ilitis, autoimmune hemolytic anemia and refractory thrombocytopenia. Though anti-dsDNA was negative, she was diagnosed to have systemic lupus erythematosus (SLE). Terminally, she had pulmonary symptoms and succumbed to her illness. The autopsy showed lupus nephritis-Class II, polyserositis, myocarditis, inflammatory myositis, immune mediated vasculitis involving renal, coronary, pancreatic, adrenal, dermal and intramuscular arteries, and pulmonary hemorrhages and edema...

Type 1 Diabetes (T1D) is a chronic pro-inflammatory autoimmune disease consisting of islet-infiltrating leukocytes involved in pancreatic β-cell lysis. One promising treatment for T1D is islet transplantation; however, clinical application is constrained due to limited islet availability, adverse effects of immunosuppressants, and declining graft survival. Islet encapsulation may provide an immunoprotective barrier to preserve islet function and prevent immune-mediated rejection after transplantation. We previously demonstrated that a novel cytoprotective nanothin multilayer coating for islet encapsulation consisting of tannic acid (TA), an immunomodulatory antioxidant, and poly(N-vinylpyrrolidone) (PVPON), was efficacious in dampening in vitro immune responses involved in transplant rejection and preserving in vitro islet function...

Paired box 4 (PAX4) is a key factor in the generation of insulin producing β-cells during embryonic development. In adult islets, PAX4 expression is sequestered to a subset of β-cells that are prone to proliferation and more resistant to stress-induced apoptosis. The importance of this transcription factor for adequate pancreatic islets functionality has been manifested by the association of mutations in PAX4 with the development of diabetes, independently of its etiology. Overexpression of this factor in adult islets stimulates β-cell proliferation and increases their resistance to apoptosis...

INTRODUCTION: Pancreatic cysts are often observed incidentally on abdominal computed tomography (CT). For cysts involving intracystic nodules, malignant neoplasms such as intraductal papillary-mucinous carcinoma (IPMC) should be suspected. In contrast, cholesterol granuloma (CG) rarely occurs in the pancreas, and CG-associated autoimmune pancreatitis (AIP) has not yet been reported. To our knowledge, this is the first reported case of AIP with CG mimicking IPMC. PRESENTATION OF CASE: A 56-year-old woman underwent abdominal CT for preoperative breast cancer screening...

OBJECTIVES: The abdominal pain associated with chronic pancreatitis (CP) may be related to the increased number and size of intrapancreatic nerves. On the other hand, patients with type 1 autoimmune pancreatitis (AIP) rarely suffer from the pain syndrome, and there are no previous studies concerning the histopathological findings of intrapancreatic nerves in patients with type 1 AIP. The current study is aimed at investigating the differences in the histopathological and immunohistochemical findings of intrapancreatic nerves in patients with CP and type 1 AIP...

Paraneoplastic neurological syndromes are rare autoimmune manifestations of malignancies associated with specific antibodies. Anti-Hu associated brainstem encephalitis, a well-described syndrome, usually presents subacutely with preferential involvement of the medulla. Anti-Hu antibodies target intraneuronal antigens and are therefore highly correlated with neurological syndromes when present concomitantly with a neoplasm. Reported is a case of anti-Hu brainstem encephalitis associated with a pancreatic neuroendocrine tumor (PNET) presenting with central hypoventilation...

Changes in diet, lifestyle and exposition to environmental risk factors account for the increased incidence of pancreatic disorders, including acute and chronic pancreatitis, and pancreatic cancer. The role of the microbiome in the development of pancreatic disorders is increasingly recognized. The translocation of gut bacteria and endotoxins following gut barrier failure is a key event contributing to the severity of acute pancreatitis, while small intestine bacterial overgrowth is common in patients with chronic pancreatitis and further worsens their symptoms and malnutrition...

BACKGROUND/AIMS: Autoimmune pancreatitis (AIP) has been associated with an increased risk of malignant diseases. We aimed to describe the incidence of malignant diseases in patients with AIP compared to the general population and to characterize the clinical presentation of these patients. METHODS: We retrospectively analyzed data from 28 patients with AIP presenting to the clinic (periods 1998 until 2010, 2012 until September 2015). We retrieved the expected cancer incidence of the general population from the German cancer registry...

Sclerosing cholangitides represent a group of chronic biliary obstructive diseases which include primary sclerosing cholangitis (PSC), IgG4 associated sclerosing cholangitis (IgG4-SC) and secondary sclerosing cholangitis (SSC). The manifestations of the diseases are similar, but their asymptomatic course is also frequent. IgG4-SC belongs to the group of IgG4 associated diseases and it is the most frequently related to type 1 autoimmune pancreatitis. Diagnosing of IgG4-SC is based on typical histopathological images, shape changes revealed by diagnostic imaging, serological tests, concurrent impairment of other organs and response to therapy, where IgG4-SC responds well to treatment with corticoids, whereas the only possibility for the remaining units is endoscopic intervention or liver transplantation...

BACKGROUND & AIMS: Immunoglobulin G4-related disease (IgG4-RD) is characterized by increased serum levels of IgG4 and infiltration of biliary, and pancreatic, and other tissues by IgG4-positive plasma cells. We assessed the prevalence of allergy and/or atopy, serum and tissue IgE antibodies, and blood and tissue eosinophils in patients with IgG4-RD. We investigated the association between serum IgE and diagnosis and relapse of this disease. METHODS: We performed a prospective study of 48 patients with IgG4-RD, 42 patients with an increased serum level of IgG4 with other inflammatory and autoimmune conditions (disease controls), and 51 healthy individuals (healthy controls) recruited from Oxford, United Kingdom from March 2010 through March 2014, and followed for a median of 41 months (range 3-73 months)...

OBJECTIVES: Concurrent intraductal papillary-mucinous neoplasm (IPMN) and autoimmune pancreatitis (AIP) was observed in a patient (index case) at our institution. Cases of coincidental IPMN and type 1 AIP and concurrent ductal adenocarcinoma (PDAC) and AIP have been previously reported. In this study we evaluate the hypothesis that IPMN elicits an IgG4 response. METHODS: Twenty-one pancreases (including the index case) with IPMN resected at our institution were studied...

Ou Cai, Shiyun Tan
Autoimmune pancreatitis (AIP) is a special type of chronic pancreatitis which is autoimmune mediated. The international consensus diagnostic criteria (ICDC) 2011 proposed two types of AIP: type I is associated with histological pattern of lymphoplasmacytic sclerosing pancreatitis (LPSP), characterized by serum IgG4 elevation, whereas type 2 is named idiopathic duct-centric pancreatitis (IDCP), with granulocytic epithelial lesion (GEL) and immunoglobulin G4 (IgG4) negative. The pathogenic mechanism is unclear now; based on genetic factors, disease specific or related antigens, innate and adaptive immunity may be involved...
