BACKGROUND: Increased protease activity is a key pathological feature of inflammatory bowel disease (IBD). However, the differences in extracellular matrix remodelling (ECM) in Crohn's disease (CD) and ulcerative colitis (UC) are not well described. An increased understanding of the inflammatory processes may provide optimized disease monitoring and diagnostics. We investigated the tissue remodelling in IBD and IBS patients by using novel blood-based biomarkers reflecting ECM remodelling...

Inflammatory bowel disease (IBD) patients are at an increased risk of developing colorectal cancer (CRC), which is thought to develop via the adenoma-carcinoma pathway. Since the discovery of the serrated carcinogenesis pathway and serrated polyposis syndrome (SPS), the incidence of carcinomas arising from serrated lesions in IBD patients has increased. We report three cases of long-standing IBD patients with associated serrated polyposis syndrome. At present, the pathophysiology of serrated lesions in IBD patients is not fully understood and there is a lack of strong evidence to confirm whether the manifestation of both conditions represents an increased risk of developing cancer...

BACKGROUND: Very early onset inflammatory bowel disease, diagnosed in children ≤5 years old, can be the initial presentation of some primary immunodeficiencies. METHODS: In this study, we describe a 17-month-old boy with recurrent infections, growth failure, facial anomalies, and inflammatory bowel disease. Immune evaluation, whole-exome sequencing, karyotyping, and methylation array were performed to evaluate the child's constellation of symptoms and examination findings...

Mechanical low back pain (LBP) is an injury or derangement of an anatomic structure in the low back. When evaluating patients with LBP, clinicians should maintain clinical suspicion for vertebral fracture, cancer, and cauda equina syndrome. Management includes patient education focused on exercise, massage, and behavioral approaches such as cognitive behavioral therapy. Acupuncture can be an effective alternative and specific herbal supplements may provide short-term pain relief. The prognosis for patients with mechanical LBP is good...

REVIEW

Management of intestinal strictures associated with Crohn's disease (CD) is clinically challenging despite advanced medical therapy directed toward mucosal healing to positively influence the natural course of CD-associated complications. Although medical therapy is available for inflammatory strictures, therapy of fibrostenotic strictures is the domain of surgery and endoscopy. Endoscopic balloon dilation (EBD) has been recognized as a well-established first-line procedure in terms of safety and efficacy. Although surgery is a valuable treatment modality for the management of CD-related strictures, EBD can help prevent multiple surgical interventions, which might in the long-term lead to a risk of short bowel syndrome...

Autoimmune liver diseases, which include mainly autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, and the variant syndromes, are often associated with extrahepatic autoimmune diseases. However, the association with cutaneous diseases is less well described. In the present article, we provide a systematic literature review on skin manifestations linked to each of these four autoimmune liver diseases, excluding skin manifestations of systemic diseases. The association of autoimmune hepatitis with vitiligo is well known, with a particular striking association with type 2 autoimmune hepatitis, a condition occurring almost entirely in children and adolescents, much rarer and more aggressive than type 1 autoimmune hepatitis; probable associations are also identified with alopecia areata, psoriasis, and pyoderma gangrenosum...

REVIEW
Geoffrey Burnstock
Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990's when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine) receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling...

Autoimmune and inflammatory conditions are a frequent complication in patients with reduced numbers of T cells. Here, we describe a mouse model of thymic stromal dysplasia resulting in peripheral T cell lymphopenia. In Foxn1:CFP-NTR transgenic mice, the bacterial nitroreductase enzyme is expressed in thymic epithelial cells and converts the prodrug CB1954 into a cytotoxic agent. This strategy enables titratable and durable destruction of thymopoietic tissue in early embryogenesis. Our results indicate that the resulting low levels of thymic capacity for T cell production create a predisposition for the development of a complex autoimmune syndrome, chiefly characterized by inflammatory bowel disease and lymphocytic organ infiltrations...

The endocannabinoid system (ECS) is an endogenous signalling pathway involved in the control of several gastrointestinal (GI) functions at both peripheral and central levels. In recent years, it has become apparent that the ECS is pivotal in the regulation of GI motility, secretion and sensitivity, but endocannabinoids (ECs) are also involved in the regulation of intestinal inflammation and mucosal barrier permeability, suggesting their role in the pathophysiology of both functional and organic GI disorders...

BACKGROUND: Currently, there are no histological criteria to diagnose irritable bowel syndrome (IBS). Our aims were (i) to examine the distribution of inflammatory cells in the colon of healthy and IBS subjects and (ii) to find histological diagnosis criteria for IBS. METHODS: Colonic biopsies were taken from four distinct regions of the colon from 20 controls (HC) and 11 patients with IBS (4 with constipation (IBS-C) and 7 with diarrhea (IBS-D) and embedded in paraffin...

AIM: To evaluate the role of P2Y1R in visceral hypersensitivity in rats with experimental irritable bowel syndrome. METHODS: A rat model of irritable bowel syndrome was generated by intra-colonic administration of acetic acid (AA) and assessed by histology and myeloperoxidase (MPO) activity assay. Then P2Y1R expression in the colonic tissue was detected by Western blot. In order to explore the regulatory role of P2Y1R in visceral hypersensitivity, an agonist (MRS2365) and an antagonist (MRS2179) of P2Y1R were intra-colonically administered and effects were tested through a colorectal distension test...

Celiac disease, an inflammatory disease of small bowel caused by sensitivity to dietary gluten and related protein, affects approximately 0.5-1% of the population in the Western world. Extraintestinal symptoms and associated diseases are increasingly recognized including diabetes mellitus type 1, thyroid disease, dermatitis herpetiformis and ataxia. There have also been a number of reports of various types of renal involvement in patients with celiac disease including diabetes nephropathy, IgA nephropathy, membranous nephropathy, membranoproliferative glomerulonephritis, nephrotic syndrome related to malabsorption, oxalate nephropathy, and associations of celiac disease with chronic kidney disease and end-stage kidney disease...

Gut microbiota forms a catalog of about 1000 bacterial species; which mainly belong to the Firmicutes and Bacteroidetes phyla. Microbial genes are essential for key metabolic processes; such as the biosynthesis of short-chain fatty acids (SCFA); amino acids; bile acids or vitamins. It is becoming clear that gut microbiota is playing a prevalent role in pathologies such as metabolic syndrome; type 2 diabetes (T2D); inflammatory and bowel diseases. Obesity and related diseases; notably type 2 diabetes, induce gut dysbiosis...

Non-alcoholic fatty liver disease (NAFLD) occurs with higher prevalence in patients with inflammatory bowel disease (IBD) relative to the general population, and susceptibility is related to the metabolic syndrome, as well as higher prevalence of bowel resection and gut microbiotal factors. Liver complications, including NAFLD and primary sclerosing cholangitis (PSC) contribute to treatment and prognosis of patients with IBD. However, the potential interplay of NAFLD and PSC is not well understood. We retrospectively assessed severity of steatosis and steatohepatitis in liver specimens from 49 patients with IBD only, 44 with IBD and co-morbid PSC, and 30 with IBD and PSC after liver transplantation...

The mechanisms underlying chronic pain states, including osteoarthritis, differ from those underlying acute pain. In chronic pain states, central nervous system (CNS) factors often play a particularly prominent role. In many individuals with chronic pain, pain can occur with minimal or no evidence of ongoing nociceptive input. Medical subspecialties have applied a wide-range of labels to these pain conditions including fibromyalgia, irritable bowel syndrome and interstitial cystitis to name just a few. These same CNS processes can augment or magnify pain when there is ongoing nociceptive input, as in conditions such as osteoarthritis or autoimmune disorders...
