OBJECTIVE: Several factors influence the clinical course of autoimmune inflammatory diseases such as MS and inflammatory bowel disease. Only recently, the complex interaction between the gut microbiome, dietary factors, and metabolism has started to be appreciated with regard to its potential to modulate acute and chronic inflammation. One of the molecular sensors that mediates the effects of these environmental signals on the immune response is the aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor with key functions in immune cells...

BACKGROUND: Intestinal fibrosis resulting in (sub)obstruction is a common complication of Crohn's disease (CD). Rho kinases (ROCKs) play multiple roles in TGFβ1-induced myofibroblast activation that could be therapeutic targets. Because systemic ROCK inhibition causes cardiovascular side-effects, we evaluated the effects of a locally acting ROCK inhibitor (AMA0825) on intestinal fibrosis. METHODS: Fibrosis was assessed in mouse models using dextran sulfate sodium and adoptive T cell transfer...

Pyostomatitis vegetans is a disease of the gingiva and the oral mucosa with noticeable, uncommon morphology. Clinical characteristics of this rare disease and considerations regarding differential diagnosis are described. Pyostomatitis vegetans is frequently associated with chronic inflammatory bowel diseases and can, thus, give a diagnostic hint at an existing ulcerative colitis or Crohn’s disease. A therapy plan for pyostomatitis vegetans is presented, which led to remission using local treatment only. The follow-up examination after one year showed that the treatment outcome had remained stable...

Inflammatory bowel disease (IBD) is characterized by recurrent or chronic inflammation of the gastrointestinal tract, which results in increased risk of developing cancer. Anorectal malignant melanoma is often misdiagnosed as either hemorrhoids or benign anorectal conditions in inflammatory bowel disease. Therefore, the overall prognosis and survival of IBD are poor. To date, the best treatment strategy remains controversial. Only early diagnosis and complete excision yield survival benefit. Here, we report a 64-year-old woman with ulcerative colitis, who was found to have anal malignant melanoma on routine colonoscopy...

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease which is associated with inflammatory bowel disease (IBD) in most cases. As there is currently no medical therapy which alters the natural history of PSC, liver transplantation may be required. Areas covered: We searched for articles in PubMed and critically reviewed current literature on the interrelationship between PSC and IBD with a specific focus on considerations for patients in the liver transplant setting. Expert commentary: PSC is an uncommon disease which limits available studies to be either retrospective or contain relatively small numbers of patients...

BACKGROUND: Increased delivery of taurine-conjugated bile acids to the distal bowel can lead to dysbiosis resulting in colitis in mouse models of inflammatory bowel disease. A similar situation also could occur in cats with intestinal disease and might therefore result in decreased whole-body taurine concentration. HYPOTHESIS/OBJECTIVES: To determine whether whole-blood taurine concentrations are decreased at the time of diagnosis in cats with intestinal disease and to correlate concentrations with clinical and laboratory variables...

BACKGROUND: Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic inflammatory disorders of the gastrointestinal tract. A combination of environmental factors and interactions with a genetic predisposition are suggested to play an important role in the etiology and pathogenesis of the IBD. Glutathione S-transferases (GSTs) are multifunctional enzymes involved in the cellular oxidative stress handling. Possible associations between GSTs gene polymorphisms and susceptibility to UC and CD have been reported in different population...

BACKGROUND: Antitumor immunotherapy has become a major player in cancer therapy. Ipilimumab is a humanized monoclonal antibody against the cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), an important downregulator of T-cell activation. Ipilimumab has demonstrated tumor regression and improvement in overall survival in patients with metastatic melanoma. Unfortunately, immune activation induced by this drug has been associated with several immune-mediated adverse effects, namely diarrhea and colitis...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease that is particularly troublesome for pediatric patients, as current therapeutic options consist of biologic agents and steroids which alter the immune response and have the harmful side effect of leaving the patient more susceptible to opportunistic infections and eventual surgery. Another option for therapy exists in the form of serum-derived bovine immunoglobulin/protein isolate (SBI), the key ingredient in a medical food, EnteraGam®. The FDA has reviewed the safety of SBI and issued a no challenge letter to the generally recognized as safe (GRAS) findings for this medical food...

Type 2 autoimmune pancreatitis, an increasingly recognized etiology of pancreatitis in patients less than 20 years old, has characteristically been diagnosed with the histological finding of duct-centric pancreatitis in a patient who lacks elevated serum immunoglobulin G4. We present the case of a nonobese 15-year-old male, without any chronic medical conditions, who presented with the chief complaint of abdominal pain. The laboratory study results were remarkable for a lipase level of 5,419 U/L and a γ-glutamyl transferase level of 373 U/L...

The use of bowel ultrasonography (US) for the evaluation of gut diseases has increased in recent years and has been proven to provide a widely available, non-invasive and inexpensive method for the initial work-up and follow-up of different intestinal diseases, limited mostly by technical challenges posed by the patient's anatomy. The present review aims to provide an extensive overview of the main pathologic features at US examination of intestinal diseases other than inflammatory bowel disease, both acute (e...

T-helper cell 17 (Th17) mediated inflammation is associated with various diseases including autoimmune encephalitis, inflammatory bowel disease and lung diseases such as chronic obstructive pulmonary disease and asthma. Differentiation into distinct Th subtypes needs to be tightly regulated to ensure an immunological balance. As microRNAs (miRNAs) are critical regulators of signaling pathways, we aimed to identify specific miRNAs implicated in controlling Th17 differentiation. We were able to create a regulatory network model of murine Th cell differentiation by combining Affymetrix mRNA and miRNA arrays and in-silico analysis...

Iron deficiency, even in the absence of anemia, can be debilitating, and exacerbate any underlying chronic disease, leading to increased morbidity and mortality. Iron deficiency is frequently concomitant with chronic inflammatory disease; however, iron deficiency treatment is often overlooked, partially due to the heterogeneity among clinical practice guidelines. In the absence of consistent guidance across chronic heart failure, chronic kidney disease and inflammatory bowel disease, we provide practical recommendations for iron deficiency to treating physicians: definition, diagnosis, and disease-specific diagnostic algorithms...

Gastrointestinal amyloidosis (GIA), a protein deposition disorder, represents a complex common pathway that encompasses multiple etiologies and presentations. It represents a significant diagnostic and treatment challenge. The disease results from the deposition of insoluble extracellular protein fragments that have been rendered resistant to digestion. GIA can be acquired or genetic, and most commonly results from chronic inflammatory disorders (AA amyloidosis), hematologic malignancy (AL amyloidosis), and end-stage renal disease (Beta-2 amyloidosis)...

Inflammatory bowel disease (IBD) is a heterogeneous group of chronic diseases with a rising prevalence in the pediatric population, and up to 25% of IBD patients are diagnosed before 18 years of age. Adolescents with IBD tend to have more severe and extensive disease and eventually require graduation from pediatric care toadult services. The transition of patients from pediatric to adult gastroenterologists requires careful preparation and coordination, with involvement of all key players to ensure proper collaboration of care and avoid interruption in care...

Crohn's disease (CD) is a chronic, non-specific granulomatous inflammatory disorder that commonly affects the small intestine and is a phenotype of inflammatory bowel disease (IBD). CD is prone to relapse, and its incidence displays a persistent increase in developing countries. However, the pathogenesis of CD is poorly understood, with some studies emphasizing the link between CD and the intestinal microbiota. Specifically, studies point to the brain-gut-enteric microbiota axis as a key player in the occurrence and development of CD...

Inflammatory bowel disease (IBD) is a complex set of diseases that lead to chronic inflammation in the gastrointestinal tract. Although the etiology of IBD is not fully understood, it is well-known that the intestinal microbiota is associated with the development and maintenance of IBD. Manipulation of the gut microbiota, therefore, may represent a target for IBD therapy. Fecal microbiota transplantation (FMT), where fecal microbiota from a healthy donor is transplanted into a patient's GI tract, is already a successful therapy for Clostridium difficile infection...
