BACKGROUND: Ipilimumab and programmed death (PD) 1-antibodies are effective treatment options in metastatic melanoma. The safety and efficacy of ipilimumab in patients with pre-existing autoimmune disorders (AD) has only been evaluated in a selected number of patients. METHODS: We performed a retrospective analysis in 14 German skin cancer centers for patients with metastatic melanoma and pre-existing AD treated with ipilimumab. RESULTS: 41 patients with 44 pre-existing AD were treated with ipilimumab (thyroiditis n = 15, rheumatoid n = 11, dermatologic n = 10, Crohn's disease/ulcerative colitis n = 3, neurological n = 2, sarcoidosis n = 2, pancreatitis n = 1)...

BACKGROUND: Pancreatic autoantibodies (PABs) are detected in patients with inflammatory bowel disease (IBD). Their prevalence is higher in Crohn's disease (CrD) than in ulcerative colitis (UC). Glycoprotein 2 (GP2) and, more recently, CUB and zona pellucida-like domain-containing protein 1 (CUZD1) have been identified as target autoantigens of PAB. The clinical utility of CUZD1 autoantibodies has only recently been assessed by indirect immunofluorescence (IIF) assays. In this study, we developed and validated novel immunoassays for the detection of CUZD1 autoantibodies...

INTRODUCTION: IL-6 is involved in a variety of diseases such as acute or chronic inflammation and autoimmune diseases, and the modulation of IL-6 level is recognized as an important target. Therefore, the blocking agent of IL-6 receptor (IL-6R), particularly anti-IL-6R antibody, was invented and its clinical efficacy was well resolved. However, it has not been shown that synergistic effects can be achieved by the combination of anti-IL-6R antibody with immunosuppressants. AREAS COVERED: This patent assessed the possible use of anti-IL-6R antibody (tocilizumab) plus methotrexate (MTX) for the treatment of acute or chronic inflammatory diseases and autoimmune diseases including nephritis, Crohn's disease, ulcerative colitis, pancreatitis, juvenile idiopathic arthritis, rheumatoid arthritis, and psoriasis...

Crohn's disease, a transmural inflammatory bowel disease, has many well-known extra-intestinal manifestations and complications. Although acute pancreatitis has a higher incidence in patients with Crohn's disease as compared to the general population, acute pancreatitis is still relatively uncommon in patients with Crohn's disease. Patients with Crohn's disease are at an approximately fourfold higher risk than the general population to develop acute pancreatitis. The risk of developing acute pancreatitis is higher in females as compared to males...

BACKGROUND/AIMS: IgG4-related autoimmune disease can exist in other organs even when there is no evidence of autoimmune pancreatitis. The aim of our study was to determine the prevalence of IgG4-positive plasma cells in the histopathological evaluations of colon biopsy specimens in IBD patients. MATERIALS AND METHODS: The number of IgG4-positive plasma cells with strong cytoplasmic immunoreactivity was counted in each colon biopsy from inflammatory bowel disease patients who had no evidence of autoimmune pancreatitis...

BACKGROUND Digestive and liver diseases (LD) are among the most common causes of mortality and morbidity in Iran and throughout the world. We have aimed to report the etiology and outcome of gastrointestinal and LD that needed admission in a typical tertiary referral hospital in Tehran during the last decade. METHODS Shariati Hospital Gastroenterology and Liver Disease Department (GI & LD) was established in 1974. Information on admitted patients in this department, such as age, gender, clinical, laboratory and imaging results, fi nal diagnosis (according to ICD-10), and hospital outcome have been regularly collected by a special summary form since 1999...

Autoimmune diseases are a heterogeneous group of disorders affecting different organs and tissues. New tools, such as genome-wide association studies, have provided evidence for new susceptibility loci and candidate genes in the disease process including common susceptibility genes involved in the immunological synapse and T cell activation. Close linkages have been found in a number of diseases, including ankylosing spondylitis, multiple sclerosis, Crohn's disease and insulin-dependent diabetes mellitus (Type 1 diabetes mellitus)...

The distinction of Crohn's disease from ulcerative colitis is based on clinical, endoscopic, radiological, and histological findings, a paradigm that remains unchanged despite the advent of new understanding of the immunological and genetic basis of inflammatory bowel disease. There is a strong correlation between inflammatory bowel disease, predominantly ulcerative colitis, and autoimmune pancreatitis. We hypothesized that colonic biopsies from patients with inflammatory bowel disease would demonstrate increased numbers of IgG4-positive plasma cells and that this elevation might be restricted to ulcerative colitis...

CUZD1, the CUB, and zona pellucida-like domains-containing protein 1, is a newly identified antigen of pancreatic autoantibodies (PAB) giving a reticulogranular pattern in patients with inflammatory bowel diseases, and in particular Crohn's disease. The exact mechanisms by which this pancreatic antigen becomes the target of IBD-specific pancreatic autoantibodies are unclear. At the same time, evolving data strongly support a role for CUZD1 in carcinogenesis. Human CUZD1 is mapped at chromosome 10q26.13 and the loss of this region is a frequent event in various malignant tumours...

Inflammatory bowel disease (IBD) is reported to be associated with autoimmune pancreatitis and IgG4-related sclerosing disease. We report a case of a 28 year old African American male with a long history of upper gastrointestinal tract Crohn's disease (CD) with multiple surgeries who developed medically refractory disease with small bowel obstruction. He had abnormal liver function tests with imaging evidence of chronic pancreatitis and ampullary inflammatory process. He underwent Whipple's procedure. Histopathological evaluation of surgical specimens of the ampulla and distal common bile duct showed accumulation of IgG4-positive plasma cells in the lamina propria...

High levels of IgG₄-positive plasma cells are commonly seen in autoimmune pancreatitis. It has recently become evident that autoimmune pancreatitis is one component of a larger multi-system disease. IgG₄-positive plasma cells have been identified in many extrapancreatic tissues, including the colon, biliary tract, liver, and lungs, and thus the term "IgG₄-related sclerosing disease" has been proposed. Awareness of IgG₄-related sclerosing disease is important, as it has been shown to mimic other conditions like malignancy...

Diseases involving the hepatopancreatobiliary (HPB) system are frequently encountered in patients with inflammatory bowel disease (IBD). Hepatobiliary manifestations constitute some of the most common extraintestinal manifestations of IBD. They appear to occur with similar frequency in patients with Crohn's disease or ulcerative colitis. HPB manifestations may occur in following settings: 1) disease possibly associated with a shared pathogenetic mechanism with IBD including primary sclerosing cholangitis (PSC), small-duct PSC/pericholangitis and PSC/autoimmune hepatitis overlap, acute and chronic pancreatitis related to IBD; 2) diseases which parallel structural and physiological changes seen with IBD, including cholelithiasis, portal vein thrombosis, and hepatic abscess; and 3) diseases related to adverse effects associated with treatment of IBD, including drug-induced hepatitis, pancreatitis (purine-based agents), or liver cirrhosis (methotrexate), and reactivation of hepatitis B, and biologic agent-associated hepatosplenic lymphoma...

Because of the wide variations in the clinical presentation of celiac disease and because treatment exists that is effective in most cases, screening of the general population for celiac disease has been considered. There is still no evidence that patients who have symptom-free celiac disease are at increased risk of small intestinal lymphoma or other complications. Prevention of osteoporosis seems to be the strongest indicator for widespread screening today [22]. The major cause of failure to respond to a gluten-free diet is continuing ingestion of gluten, but other underlying diseases must be considered...

BACKGROUND: The pathology of non-alcoholic chronic pancreatitis has not yet been sufficiently studied. AIMS: To identify the major changes of pancreatic tissue in patients surgically treated for non-alcoholic chronic pancreatitis. PATIENTS: Pancreatectomy specimens from 12 patients with non-alcoholic chronic pancreatitis, including four patients with autoimmune or related diseases (Sjögren's syndrome, primary sclerosing cholangitis, ulcerative colitis, and Crohn's disease), were reviewed...

The sera of 59 patients with Crohn's disease (CD) and of 46 patients with ulcerative colitis (UC) were tested for autoantibodies (Aab) by indirect immunofluorescence with modern histochemical techniques using 19 different human tissues as antigenic substrates. Control collectives consisted of 19 patients with coeliac disease and of 100 healthy subjects. It was possible to demonstrate a specific marker for CD: Aab against exocrine pancreas (Pab) were present in 39% of the CD sera (UC 4%, coeliac disease 0%, healthy controls 3%)...
