The mucus gel covers the wet epithelia that forms the inner lining of the body. It constitutes our first line of defense protecting the body from infections and other deleterious molecules. Failure of the mucus barrier can lead to the inflammation of the mucosa such as in inflammatory bowel diseases. Unfortunately, there are no effective strategies that reinforce the mucus barrier properties to recover or enhance its ability to protect the epithelium. Herein, we describe a mucus engineering approach that addresses this issue where we physically crosslink the mucus gel with low molar mass chitosan variants to reinforce its barrier functions...

BACKGROUND: Neuroendocrine tumors (NETs) metastasize to the liver. Everolimus and selective internal radioembolization (SIRT) are approved treatments. Pasireotide is a somatostatin analogue with an affinity for somatostatin receptors 1, 2, 3, and 5. Everolimus and pasireotide may potentiate SIRT radiosensitization and inhibit rebound angiogenesis. This study evaluated the safety of pasireotide, everolimus, and SIRT. METHODS: This 3 + 3 phase 1 trial evaluated 3 dose levels of everolimus (2...

Inflammatory bowel diseases, Crohn's disease and ulcerative colitis are chronic relapsing conditions that may result in progressive bowel damage, high risk of complications, surgery and permanent disability. The conventional therapeutic approach for inflammatory bowel diseases is based mainly on symptom control. Unfortunately, a symptom-based therapeutic approach has little impact on major long-term disease outcomes. In other chronic disabling conditions such as diabetes, hypertension and rheumatoid arthritis, the development of new therapeutic approaches has led to better outcomes...

As expected, pharmacy costs increased with the introduction of this new treatment in a market dominated by over-the-counter and generic treatments. On the other hand, outpatient GI-related and irritable bowel disease health care resource use and costs substantially decreased among commercial and Medicare patients following linaclotide treatment initiation.

BACKGROUND: Celiac disease (CD) is a chronic inflammatory enteropathy with a symptom spectrum similar to that of irritable bowel syndrome (IBS). CD is a common, but largely undiagnosed, condition in Western countries. However, it is extremely rare among Chinese people, and few studies have evaluated its prevalence in China. OBJECTIVE: To determine the prevalence of CD in IBS patients diagnosed using the Rome III criteria in North China. METHODS: This was a single-center, prospective, controlled cohort study performed in Qilu Hospital involving 246 IBS patients and 246 healthy controls...

Kaposi sarcoma is an unusual tumor associated to a human herpes virus-8 infection involving the skin or internal organs. Iatrogenic Kaposi's sarcoma often occurs in patients receiving immunosuppressive therapy. So far, a few Kaposi's sarcoma cases have been reported in the literature associated with inflammatory bowel diseases. We report a 53-year-old male diagnosed with a severe refractory ulcerative colitis who was treated with corticosteroids and azathioprine. The patient underwent a colectomy after the failure of medical treatment...

Obesity is a global epidemic affecting chronic inflammatory diseases. Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease that can occur as an extraintestinal manifestation of inflammatory bowel disease (IBD). Previously we reported that patients with PSC who are obese have a higher risk of advanced liver disease. Currently it is unknown how obesity accelerates or worsens PSC. We evaluated the progression of PSC in an antigen-driven cholangitis mouse model of diet-induced obesity. Obesity was induced in our murine model of immune-mediated cholangitis (OVAbil)...

OBJECTIVE: Inflammatory bowel disease (IBD) is generally reported to be associated with spondylarthropathies (SpA) in 5%-15% of cases. Systematic colonoscopic assessment by protocol demonstrated mucosal inflammation characteristic of Crohn disease (CD) in up to one-third of patients with SpA. Video capsule endoscopy (CE) is a superior diagnostic tool to detect small bowel mucosal disease. Our study compared the accuracy of CE to standard colonoscopy for detection of inflammatory bowel lesions in patients with SpA, and to describe predictors of small bowel inflammation (SBI) in this cohort...

Enterocutaneous fistulae (ECF) and enteroatmospheric fistulae (EAF) are difficult complications that primarily arise after abdominal surgical procedures. Development of an ECF or EAF carries significant mortality and morbidity. Effective management of patients with these disease states requires a multidisciplinary approach, which includes surgical, pharmacotherapeutic, and nutritional interventions. This review focuses on the medical and nutritional management of ECF/EAF, providing background on drug agents and nutritional strategies that may be helpful in reducing effluent volume, optimizing fistula healing, and maintaining nutritional health...

Inflammatory Bowel Diseases, such as Crohn's disease (CD) and Ulcerative Colitis (UC), are widespread diseases (with an estimated 2.2 million Europeans affected), and even populations previously considered 'low risk' (such as Japan and India) are witnessing an increasing incidence. CD is a chronic, progressive immunologically driven disease, with an evolution characterized by succession of periods of progression and remission. New physiopathological pathways are continuously being discovered, the more we understand about how the disease appears and progresses, the more targets become available for the development of novel therapies...

Ulcerative colitis (UC) is a major inflammatory bowel disease (IBD) has become a worldwide emergent disease. Veronica polita (VP) is a medicinal herb that has strong antioxidant and anti-inflammatory properties. In the present study, we studied the protective effect of VP on dextran sulfate sodium (DSS)-induced experimental colitis in mice. Phytochemical screening of VP extract demonstrated the presence of high total phenolic and flavonoid contents. Compared with the DSS group, VP significantly reduced clinical symptoms with less weight loss, bloody stool, shortening of the colon, and the severity of colitis was considerably inhibited as evidenced by the reduced disease activity index (DAI) and degree of histological damage in the colon and spleen...

The initiating factors that trigger inflammatory bowel disease (IBD) are poorly understood. In a recent paper, Yang et al. (2017) demonstrate that IBD-like syndrome in mice can develop as a consequence of recurrent pathogen infection. Pathogenic triggering of inflammatory disease is a re-emerging concept that has significant therapeutic implications.

Autophagy is genetically associated with inflammatory bowel disease (IBD); however, its role remains unclear in disease pathogenesis. Three recent studies reveal a novel cytoprotective role of autophagy during viral, bacterial, and protozoan-triggered IBD (Burger et al., 2018; Matsuzawa-Ishimoto et al., 2017; Pott et al., 2018).

Neutrophilic urticarial dermatosis (NUD) is a useful diagnostic term for urticarial lesions that are less pruritic and more painful than conventional urticaria. The histopathologic features include neutrophilic infiltrates in the interstitial dermis with a higher density than idiopathic urticaria. NUD has been associated with several systemic conditions, which are predominantly autoimmune and autoinflammatory in nature. A woman with Crohn disease who developed NUD is described. Literature reports of other conditions in which neutrophilic urticarial dermatosis have been observed are also reviewed and summarized...

OBJECTIVES: Perianal Crohn's disease (CD) prevalence varies according to the disease location, being particularly frequent in patients with colonic involvement. We aimed to evaluate small bowel involvement and compare small bowel capsule endoscopy findings and inflammatory activity between patients with and without perianal disease. MATERIALS AND METHODS: Retrospective single-center study including 71 patients - all patients with perianal CD (17 patients) who performed a small bowel capsule endoscopy were included, and non-perianal CD patients were randomly selected (54 patients)...

BACKGROUND AND PURPOSE: Inflammatory bowel disease (IBD) is characterized by pain, bleeding, cramping and altered gastrointestinal (GI) function. Changes in mucosal serotonin (5-HT) signalling occur in animal models of colitis and in humans suffering from IBD. Melatonin is co-released with 5-HT from the mucosa and has a wide variety of actions in the GI tract. Here we examined how melatonin signalling is affected by colitis and determined how this relates to 5-HT signalling. EXPERIMENTAL APPROACH: Using electroanalytical approaches, we investigated how 5-HT release, reuptake and availability as well as melatonin availability are altered in dextran sodium sulfate (DSS)-induced colitis in mice...
