Trinitrobenzensulfonic acid (TNBS) is commonly used to induce an experimental inflammatory bowel disease (IBD) model. Oxidative stress and inflammation have been proposed as mechanisms underlying the pathophysiology of IBD. Aronia melanocarpa fruit juice (AMFJ) is extremely rich in polyphenolic substances, mainly proanthocyanidins, flavonoids and phenolic acids. The aim of this study was to evaluate the effect of AMFJ in a rat TNBSinduced colitis model and to compare the effect of the juice with that of sulfasalazine...

This special article reports on two crucial issues discussed during a meeting. The first was the updated management of Helicobacter pylori infection. This was approached taking into account the recent European Guidelines, with a focus on novelties in treatment. In particular, considering the increasing H. pylori antibiotic resistance to clarithromycin, in countries with a high clarithromycin resistance rate the bismuth-containing quadruple therapies should be preferred. The new formulation, with bismuth, metronidazole, and tetracycline contained in a single capsule (three-in-one), has shown exciting results both in naive and in non-responder patients...

Paeonol, as the main phenolic compound isolated from the Chinese herbs, has been confirmed to present anti-inflammatory effects on ulcerative colitis (UC) in our previous study. However, its poor solubility has hindered its development of being a favourable pharmaceutical product in treating colon diseases. In this study, we prepared the colon-specific delivery system (Pae-SME-CSC) with paeonol-loaded self-microemulsion (Pae-SMEDDS), and evaluated its in vitro and in vivo properties, especially the anti-inflammatory effects on UC rats...

The octapeptide NAP has been shown to exert neuroprotective properties and reduce neuro-inflammatory responses. The aim of the present study was to investigate if NAP provides anti-inflammatory effects in acute murine colitis. To address this, C57BL/6 j mice were challenged with 3.5% dextran sulfate sodium from day 0 until day 6 to induce colitis, either treated intraperitoneally with NAP or placebo (NaCl 0.9%) from day 1 until day 6 post-induction (p.i.) and subjected to in depth macroscopic, microscopic and immunological evaluations...

BACKGROUND: Eosinophilic colitis (EC) is a rare and ill-defined entity with an unknown pathogenesis and an unsatisfactory treatment response. The standard histopathological criteria for EC diagnosis lack specificity and not all the cases fulfilling those criteria are considered clinically as EC and treated. The objective of this study is to refine diagnostic criteria for EC. METHODS: Retrospective study of all the cases with a histopathological diagnosis of EC in Hospital Clinico San Carlos (Madrid, Spain) from 2006 to 2016...

Microscopic colitis (MC) is a chronic inflammatory bowel disease characterized by chronic watery diarrhea and diagnosed with the histologic hallmarks of disease despite a macroscopically normal large bowel. Although 2 distinct disease phenotypes exist, their clinical presentations and epidemiologic characteristics have overlapping features. This article summarizes evidence regarding the pathogenesis of MC, mechanisms of diarrhea in this cohort, and associations with medications. In addition, currently recommended and novel therapeutic approaches to achieving remission in this patient population are reviewed...

The goal of this study was explore the role of indoleamine 2, 3-dioxygenase (IDO) in the therapeutic effect of probiotics on inflammatory bowel disease (IBD). Trinitro-benzene sulfonic acid (TNBS) was used to induce colitis in mice, and 1-methyltryptophan (1-MT) was used to block the expression of IDO. Clinical manifes-tations, macroscopic and microscopic colonic alterations were assessed using the dis-ease activity index (DAI), Wallace-Keenan, and Curtner scoring systems, respectively. The expression of colonic IDO was detected by western blot...

BACKGROUND AND AIM: Microscopic colitis (MC) has been associated with increased paracellular permeability. Therefore, we aimed to investigate potential associations between MC and several genes encoding tight junction (TJ) proteins reported to interact with each other. METHODS: The association between MC and single nucleotide polymorphisms (SNP; n = 63) within TJ genes (F11R, MAGI1, MAGI2, MAGI3, PARD3, PTEN, and TJP1) were investigated in a case-control study (n MC patients = 104 and n controls = 423)...

OBJECTIVE: Ulcerative colitis (UC) is a dynamic disease with its severity continuously changing over time. We hypothesised that the risk of colorectal neoplasia (CRN) in UC closely follows an actuarial accumulative inflammatory burden, which is inadequately represented by current risk stratification strategies. DESIGN: This was a retrospective single-centre study. Patients with extensive UC who were under colonoscopic surveillance between 2003 and 2012 were studied...

Background: Bile acid diarrhoea (BAD) is a common cause of chronic diarrhoea with a population prevalence of primary BAD around 1%. Previous studies have identified associations with low levels of the ileal hormone fibroblast growth factor 19 (FGF19), obesity and hypertriglyceridaemia. The aim of this study was to identify further associations of BAD. Methods: A cohort of patients with chronic diarrhoea who underwent 75selenohomocholic acid taurate (SeHCAT) testing for BAD was further analysed retrospectively...

Adenosine represents a powerful modulating factor, which has been shown to orchestrate the scope, duration, and remission of the inflammatory response through the activation of four specific receptors, classified as A1, A2A, A2B, and A3, all being widely expressed in a variety of immune cells. Several selective A2A receptor agonists have displayed anti-inflammatory effects, through the suppression of IL-12, TNF, and IFN-γ production by monocytes and lymphocytes, in the setting of chronic intestinal inflammation...

Methyl gallate is a gallotannin widely distributed in nature. Previous studies have demonstrated its antioxidant, anti-inflammatory, antimicrobial and anti-tumor activities. In the present study, the activity of methyl gallate on experimental models of inflammatory bowel disease has been investigated. Experimental colitis was induced in Sprague-Dawley rats through the intracolonic instillation of an acetic acid solution (2 mL, 4% v/v). Methyl gallate (100 and 300 mg/kg, p.o.) and the reference drug mesalazine (100 mg/kg, p...

BACKGROUND: Irritable bowel syndrome (IBS) is a common condition characterised by abdominal pain, bloating, and poor quality of life. IBS might be caused by a gut dysbiosis. We aimed to compare faecal microbiota transplantation (FMT) with placebo in patients with IBS. METHODS: In this double-blind, randomised, placebo-controlled, parallel-group, single-centre study, we enrolled patients with IBS with diarrhoea or with diarrhoea and constipation (excluding dominating constipation) defined by the ROME III criteria, scored as moderate to severe according to the IBS severity scoring system (IBS-SSS; a score of ≥175)...

Brusatol (BR) is one of the main bioactive components derived from Brucea javanica, a medicinal herb historically used in the treatment of dysenteric disorders (also known as ulcerative colitis(UC)). Due to its poor aqueous solubility, a novel brusatol self-microemulsifying drug delivery system (BR-SMEDDS) nanoformulation with smaller size, higher negative zeta potential and drug content, and excellent stability was developed. The appearance of BR-SMEDDS remained clear and transparent, and transmission electron microscopy showed microemulsion droplets to be spherical with homogeneous distribution...

BACKGROUND: Epstein-Barr virus (EBV) has been associated with inflammation in the colon, particularly in patients with inflammatory bowel disease (IBD). Even if a relevant plasmocytosis, similar to IBD, is present in microscopic colitis (MC), the frequency of EBV infection in this setting is unknown. OBJECTIVES: We aimed to compare the frequency of colonic EBV infection in patients with MC, ulcerative colitis (UC), and irritable bowel syndrome (IBS). STUDY DESIGN: The frequency of colonic EBV infection in biopsies of 30 patients with MC, 30 patients with UC, and 30 controls with IBS was retrospectively assessed...
