IMMUNOLOGICAL ASPECTS OF CROHN’S DISEASE: A REGULATORY FUNCTION OF TIM-3/ GALECTIN-9 IN LYTH1

2017

Crohn's disease (CD) is a type of inflammatory bowel disease (IBD) and its etiology is multifactorial and involves a combination of genetic and environmental factors. The interaction of these factors causes an imbalance in the microbiota, leading to the activation of several immunological and inflammatory mechanisms. From an immunological point of view, there seems to be an involvement of the TIM-3/galectin-9 pathway and of the autoregulation of LyTh1. The studies show that in patients with CD the autoregulation of LyTh1 is lost due to a reduced concentration of galectin-9 and a reduced TIM-3 expression in LyTh1. This could be one of the reasons for the state of perpetual activation in LyTh…

Incidence, Clinical Characteristics and Management of Inflammatory Bowel Disease in Spain: Large-Scale Epidemiological Study

2021

(1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD—Crohn’s disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)—during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and…

Activities related to inflammatory bowel disease management during and after the coronavirus disease 2019 lockdown in Italy: How to maintain standard…

2020

BACKGROUND AND AIMS: Restructuring activities have been necessary during the lockdown phase of the coronavirus disease 2019 (COVID-19) pandemic. Few data are available on the post-lockdown phase in terms of health-care procedures in inflammatory bowel disease (IBD) care, and no data are available specifically from IBD units. We aimed to investigate how IBD management was restructured during the lockdown phase, the impact of the restructuring on standards of care and how Italian IBD units have managed post-lockdown activities. METHODS: A web-based online survey was conducted in two phases (April and June 2020) among the Italian Group for IBD affiliated units within the entire country. We inv…

What new endoscopic imaging modalities will become important in the diagnosis of IBD?

Imaging techniques in inflammatory bowel disease: recent trends, questions and answers

2009

Summary Imaging techniques have undergone substantial progress in recent years and contribute significantly in the diagnosis of inflammatory bowel diseases in conjunction with patient history, clinical and laboratory examination. Modern cross-sectional imaging modalities such as computed tomography and magnetic resonance imaging allow an evaluation not only of the complete bowel wall of the small intestine, but also of extraluminal structures. They constitute a major diagnostic component in the initial workup, in stricturing or fistulizing disease and in suspected abscess. Transabdominal ultrasonography has been re-appreciated in these settings as an easy- and ready-to-use tool yielding rea…

Abincol® (Lactobacillus plantarum LP01, Lactobacillus lactis subspecies cremoris LLC02, Lactobacillus delbrueckii LDD01), an oral nutraceutical, prag…

2019

Chronic intestinal disorders (CID), including inflammatory bowel disease (IBD), such as ulcerative colitis and Crohn’s disease, irritable bowel syndrome (IBS), and diverticular disease (DD), are diseases that relapse episodes. There is evidence that patients with CID have intestinal dysbiosis, so probiotics may counterbalance the impaired microbiota. Therefore, the current survey evaluated the efficacy and safety of Abincol®,an oral nutraceuticalcontaining a probiotic mixture with Lactobacillus plantarum LP01 (1 billion of living cells), Lactobacillus lactis subspecies cremoris LLC02 (800 millions of living cells), and Lactobacillus delbrueckii LDD01 (200 millions of living cells), in 3,460…

Hyaluronic Acid Increases Anti-Inflammatory Efficacy of Rectal 5-Amino Salicylic Acid Administration in a Murine Colitis Model

2021

5-amino salicylic acid (5-ASA) is a standard therapy for the treatment of mild to moderate forms of inflammatory bowel diseases (IBD) whereas more severe forms involve the use of steroids and immunosuppressive drugs. Hyaluronic acid (HA) is a naturally occurring non-sulfated glycosaminoglycan that has shown epithelium protective effects in experimental colitis recently. In this study, both 5-ASA (30 mg/kg) and HA (15 mg/kg or 30 mg/kg) were administered rectally and investigated for their potential complementary therapeutic effects in moderate or severe murine colitis models. Intrarectal treatment of moderate and severe colitis with 5-ASA alone or HA alone at a dose of 30 mg/kg led to a sig…

Immunomodulatory drugs: Oral and systemic adverse effects

2013

Objectives: The main objectives are to present the different adverses effects of the immunomodulatory drugs that can impair the quality of life of the immunosupressed patients and study the impact of immunomodualtion on oral diseases. Immunomodulatory drugs have changed the treatment protocols of many diseases where immune functions play a central role, such as rheumatic diseases. Their effect on oral health has not been systematically investigated, however. Study Design: We review current data on the new immunomodulatory drugs from the oral health perspective based on open literature search of the topic. Results: These target specific drugs appear to have less drug interactions than earlie…

Guanosine prevents nuclear factor-κB nuclear translocation ameliorating experimental colitis in rats

2018

Background inflammatory bowel diseases (IBDs), including Crohn’s disease (CD) and ulcerative colitis (UC), are prevalent and debilitating health problems worldwide. Due to the adverse effects of classical treatment for IBD, therapeutic options and approaches for these diseases continue to evolve. Guanosine, a guanine-based purine, is an extracellular signalling molecule that seems to exert anti-inflammatory and antioxidative effects in several in vivo and in vitro injury models. The aim of the present study was to investigate whether exogenous guanosine may have protective effects on 2,4-dinitrobenzene sulfonic acid (DNBS)-induced Colitis in rat. Methods Experimental Colitis was induced by …

New therapeutic strategies for treatment of inflammatory bowel disease

2008

Although the precise etiology of inflammatory bowel disease (IBD) still remains unclear, considerable progress has been made in the identification of cytokine-mediated signaling pathways involved in the inflammatory process. Recent data have clearly shown that these pathways induce augmented intestinal T-cell activation and thus resistance to apoptosis, which is a central process in disease pathogenesis, as it impairs mucosal homeostasis. Therefore, novel therapeutic strategies aim at restoring activated effector T-cell susceptibility to apoptosis in the gut, based on a pathophysiological rationale. This development is best exemplified by the emergence of agents that target the TNF pathway,…
