#1
REVIEW
Geoffrey Burnstock, Kenneth A Jacobson, Fievos L Christofi
Purinergic receptors are implicated in the pathogenesis of gastrointestinal disorders and are being explored as potential therapeutic targets. Gut inflammation releases ATP that acts on neuronal, glial, epithelial and immune cells. Purinergic signalling in glia and neurons is implicated in enteric neuropathies. Inflammation activates glia to increase ATP release and alter purinergic signalling. ATP release causes neuron death and gut motor dysfunction in colitis via a P2X7-dependent neural-glial pathway and a glial purinergic-connexin-43 pathway...

Inflammatory bowel disease (IBD) is an idiopathic prolonged ailment accountable for inflammatory conditions of the intestine. Moreover, arthritis is responsible for joints' stiffness and painful inflammation. IBD shows certain articular extra-intestinal manifestations associating IBD with arthritis. IBD associated arthritis is found to be linked with ankylosing spondylitis (AS). The present study insights for the potential and putative drug targets and biomarkers of IBD associated with arthritis using in silico approaches...

BACKGROUND: Prior studies have shown poor compliance with quality measures for IBD at academic and private practices. We sought to provide focused interventions to improve compliance and documentation with the IBD measures. METHODS: Two centers, academic practice (AP) and private practice (PP), initially reviewed their compliance with eight established IBD quality measures in consecutive charts. A multi-faceted intervention was developed to improve awareness and documentation of these measures...

Disability is a common worldwide health challenge and it has been increasing over the past 3 decades. The treatment paradigm has changed dramatically in inflammatory bowel diseases (IBDs) from control of symptoms towards full control of disease (clinical and endoscopic remission) with the goal of preventing organ damage and disability. These aims are broadly similar to rheumatoid arthritis and multiple sclerosis. Since the 1990s, our attention has focused on quality of life in IBD, which is a subjective measure...

Background: Adrenal insufficiency (AI) secondary to treatment with glucocorticoids (GCs) is common in patients with inflammatory bowel disease (IBD), but little is known about the relationship between AI and the clinical course in IBD. The aim of the study was to compare the clinical course in IBD patients with normal adrenal function versus patients with subnormal adrenal function. Methods: A retrospective observational study on 63 patients with IBD who had performed a low-dose short Synacthen test (LDSST) (1 μg) immediately (1-7 days) after a standard course of GCs...

Background: Thiopurines, azathioprine (AZA) and 6-mercaptopurine (6-MP) are common maintenance medications for inflammatory bowel disease (IBD). Excessive methylation via thiopurine methyltransferase (TPMT) frequently causes therapeutic failure. Allopurinol reduces excessive 6-methyl-mercaptopurine (6-MMP) while enhancing 6-thioguanine (6-TGN) levels. The aim of this study was to evaluate clinical, metabolic and endoscopic impact of allopurinol in combination with low-dose thiopurine in IBD...

Chronic abdominal and pelvic pain are common, debilitating clinical conditions experienced by millions of patients around the globe. The origin of such pain commonly arises from the intestine and bladder, which share common primary roles; the collection, storage and expulsion of waste. These visceral organs are located in close proximity to one another, and also share common innervation from spinal afferent pathways. Chronic abdominal pain, constipation or diarrhoea are primary symptoms for patients with Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD)...

Inflammatory Bowel Diseases (IBD) are chronic inflammatory gastrointestinal diseases, primarily consisting of Ulcerative Colitis (UC) and Crohn's Disease (CD). The complex nature of the disease, as well as the limited therapeutic options characterized by low efficiency and major side effects, shows the importance of developing novel strategies of therapeutic intervention in IBD. Susceptibility loci related to IBD are present only in a small percentage of IBD patients, implying that epigenetic modifications could influence the pathogenesis of the disease...

Objective: Family history is the strongest risk factor for developing Crohn's disease (CD) or ulcerative colitis (UC). We investigated whether the proximity of relationship with the affected relative and concordance for type of IBD modifies the effect of family history on phenotype and disease severity. Design: This cross-sectional study included patients with a confirmed diagnosis of IBD in a clinical registry. Family history of IBD was assessed by a questionnaire ascertaining presence of disease in a 1 st degree, 2 nd degree or a distant relative...

BACKGROUND: Psoriasiform and eczematous eruptions are the most common dermatological adverse reaction linked to anti-TNF-α therapy. Yet, a detailed characterization of their immune phenotype is lacking. OBJECTIVES: We sought to characterize anti-TNF-α induced inflammatory skin lesions on a histopathologic, cellular and molecular level, compared to psoriasis, eczema (atopic dermatitis), and healthy control skin. METHODS: Histopathologic evaluation, gene expression (quantitative RT-PCR) and computer-assisted immunohistologic studies (TissueFAXS) were performed on 19 skin biopsies from IBD (n=17) and rheumatoid arthritis (n=2) patients with new-onset inflammatory skin lesions during anti-TNF-α-therapy...

Anti-tumor necrosis factor (anti-TNF) is highly effective in inflammatory bowel disease (IBD); however, it is associated with an increased risk of infections, particularly in older adults. We reviewed 349 patients with IBD, who were observed over a 12-month period, 74 of whom had received anti-TNF therapy (71 patients were aged <60 years and 3 were aged ≥60 years). All the 3 older patients developed serious infectious complications after receiving anti-TNFs, although all of them were also on concomitant immunosuppressive therapy...

Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory condition with intestinal and extraintestinal manifestations. Medications are the cornerstone of treatment of IBD. However, patients often adhere to medication poorly. Adherence to medications is defined as the process by which patients take their medications as prescribed. Treatment non-adherence is a common problem among chronic diseases, averaging 50% in developed countries and is even poorer in developing countries. In this review, we will examine the adherence data in IBD which vary greatly depending on the study population, route of administration, and methods of adherence measurement used...

Intestinal microbiome dysbiosis has been consistently described in patients with IBD. In the last decades, Escherichia coli, and the adherent-invasive E coli (AIEC) pathotype in particular, has been implicated in the pathogenesis of IBD. Since the discovery of AIEC, two decades ago, progress has been made in unravelling these bacteria characteristics and its interaction with the gut immune system. The mechanisms of adhesion of AIEC to intestinal epithelial cells (via FimH and cell adhesion molecule 6) and its ability to escape autophagy when inside macrophages are reviewed here...

BACKGROUND: Genetic and other biological factors may lead to differences in disease behavior among children with inflammatory bowel disease of different races, which may be further modified by disparities in care delivery. Using the Kids' Inpatient Database, we aimed to evaluate differences in the management of pediatric patients with inflammatory bowel disease by race, focusing on length of stay (LOS). METHODS: We performed a cross-sectional analysis using 2000 to 2012 data from the Kids' Inpatient Database, a nationally representative database...

BACKGROUND: Infliximab (IFX) infusion may lead to development of anti-IFX antibodies, and subsequent infusion reactions (IRs). The safety of rapid IFX infusion administered over 60 minutes has been under-investigated in children with inflammatory bowel disease. In a multicenter study, the frequency and nature of rapid infusion-associated IRs were examined. METHODS: The medical records of all consecutive children with inflammatory bowel disease receiving rapid IFX infusions between January 2014 and December 2016 were reviewed...
