IBD

BACKGROUND: Janus kinase (JAK) inhibitors represent a novel therapeutic class for treatment of inflammatory bowel disease. AIMS: To determine the efficacy and safety of JAK inhibitors compared to placebo for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). METHODS: PubMed, Embase and CENTRAL were systematically searched to November 1, 2018. Randomised placebo-controlled trials (RCTs) of JAK inhibitors in adult patients with CD or UC were eligible...

BACKGROUND & AIMS: Crohn's disease (CD) is a lifelong illness with substantial morbidity, although new therapies and treatment paradigms have been developed. We provide guidance for treatment of ambulatory patients with mild to severe active luminal CD. METHODS: We performed a systematic review to identify published studies of the management of CD. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach...

BACKGROUND: Biological therapy is currently widely used to treat IBD. Infliximab, adalimumab and golimumab are currently licensed anti-TNF therapies. Biosimilar anti-TNF monoclonal antibodies are increasingly used. Anti-TNF therapies are widely used and their adverse effects are well characterised, and may cause significant morbidity and mortality in a small proportion of exposed patients. Gastroenterologists need to understand the mechanisms for these effects, recognise these swiftly and manage such events appropriately...

BACKGROUND: Faecal calprotectin [FCal] levels are used as a surrogate marker for mucosal inflammation, but thresholds for defining endoscopic or histological disease activity in ulcerative colitis [UC] remain unclear. METHODS: Using validated indices, prospective measurements of FCal, symptoms [Simple Colitis Clinical Activity Index, SCCAI], endoscopic [Ulcerative Colitis Endoscopic Index of Severity, UCEIS] and histological activity [Nancy index] were made over 6 months in patients enrolled into the TrueColours UC web-based monitoring programme...

Over the last 2 decades, novel therapies targeting several immune pathways have been developed for the treatment of patients with inflammatory bowel disease (IBD). Although anti-tumor necrosis factor (anti-TNF) agents remain the firstline treatment for moderate to severe Crohn's disease and ulcerative colitis, many patients will require alternative agents, due to nonresponse, loss of response, or intolerance of anti-TNFs. Furthermore, patients may request newer therapies due to improved safety profiles or improved administration (ie, less frequent injection, oral therapy)...

Inflammatory bowel disease (IBD) is a chronic heterogeneous group of diseases that has undergone major advances in the understanding of its etiology and pathogenesis in recent years. The development of biologics had resulted in better overall management of the disease, including lower rates of surgery and better long-term clinical and patient-reported outcomes. Treatment modalities have either been newly developed or extrapolated from their approved use for a different indication. Modes of action and treatment targets have varied as well...

Endoscopy plays a fundamental role in the diagnosis, management, and treatment of inflammatory bowel disease (IBD). Colonoscopy, flexible sigmoidoscopy, and esophagogastroduodenoscopy have long been used in the care of patients with IBD. As endoscopic technologies have progressed, tools such as endoscopic ultrasound, capsule endoscopy, and balloon-assisted enteroscopy have expanded the role of endoscopy in IBD. Furthermore, chromoendoscopy has enhanced our ability to detect dysplasia in IBD. In this review article, we will focus on the roles, indications, and limitations of these tools in IBD...

The advent of anti-TNF agents has dramatically changed the treatment algorithms for IBD in the last 15 years, but primarily and more importantly secondary loss of response is often observed. Fortunately , new treatment options have been actively explored and some have already entered our clinical practice. In the class of anti-cytokine agents, the anti-IL12/IL23 monoclonal antibodies (mAbs) have entered clinical practice with the anti-p40 mAb ustekinumab in Crohn's disease (CD). Also, more selective anti-IL23 agents (anti-p19) have shown efficacy and are being further developed, in contrast to agents inhibiting IL-17 downstream which have failed in clinical trials despite their clear efficacy in psoriasis (Verstockt et al...

Crohn's disease is an idiopathic inflammatory disorder of unknown etiology with genetic, immunologic, and environmental influences. The incidence of Crohn's disease has steadily increased over the past several decades. The diagnosis and treatment of patients with Crohn's disease has evolved since the last practice guideline was published. These guidelines represent the official practice recommendations of the American College of Gastroenterology and were developed under the auspices of the Practice Parameters Committee for the management of adult patients with Crohn's disease...

Corticosteroids and antibodies to tumor necrosis factor (anti-TNF) are mainstays of treatment of acutely active IBD and while anti-TNF therapy is indicated for maintenance therapy, chronic corticosteroid therapy is associated with known significant risks. Nonetheless, chronic or recurrent corticosteroid treatment in IBD is common. In this edition of the journal Lewis et al. use Medicaid and Medicare databases to contrast adverse outcomes in persons with IBD and either corticosteroid or anti-TNF use. Compared to high dose corticosteroid use, anti TNF therapy is associated with less risk for death in Crohn's disease but no statistical difference in death outcomes in ulcerative colitis...

Current therapies used in the treatment of inflammatory bowel disease (IBD) are not effective in all patients. Biologic agents result in approximately 40% remission rates at 1 year in selected populations, prompting a growing interest in combining biologic therapy to improve outcomes. There are limited published data regarding the efficacy and safety of combination targeted therapy in IBD specifically, which include only 1 exploratory randomized control trial and 3 case reports or series. This review evaluates the published literature regarding this therapeutic paradigm in IBD and its extensive utilization in the treatment of other immune-mediated inflammatory disorders...

The management of inflammatory bowel disease (IBD) has been transformed over the last two decades by the arrival of tumor necrosis factor (TNF) antagonist agents. Recently, alternative drugs have been approved, directed at leukocyte-trafficking molecules (vedolizumab) or other inflammatory cytokines (ustekinumab). New therapeutics are currently being developed in IBD and represent promising targets as they involve other mechanisms of action (JAK molecules, Smad 7 antisense oligonucleotide etc.). Beyond TNF antagonist agents, these alternative drugs are needed for early-stage treatment of patients with aggressive IBD or when the disease is resistant to conventional therapy...

OBJECTIVES: Corticosteroid-free remission is an emerging treatment goal in the management of inflammatory bowel disease (IBD). In the population-based Inflammatory Bowel Disease South Limburg cohort, we studied temporal changes in corticosteroid use and assessed the corticosteroid-sparing effects of immunomodulators and biologicals in real life. METHODS: In total, 2,823 newly diagnosed patients with Crohn's disease (CD) or ulcerative colitis (UC) were included. Corticosteroid exposure and cumulative days of use were compared between patients diagnosed in 1991-1998 (CD: n=316, UC: n=539), 1999-2005 (CD: n=387, UC: n=527), and 2006-2011 (CD: n=459, UC: n=595)...

Crohn's disease (CD) is a chronic progressive destructive inflammatory bowel disease. As in rheumatoid arthritis, there is increasing evidence that early treatment initiation with disease-modifying agents, such as biological drugs, may lead to complete disease control, prevention of disease progression thus protecting against irreversible damage and restoration of normal quality of life. Data from randomised clinical trials with immunosuppressants and biologics suggest that treating patients with a disease duration of <2 years and an absence of complications may significantly reduce the risk for complications and increase time in remission in patients with CD...

World IBD Day is recognized on May 19 to raise awareness of inflammatory bowel disease (IBD) and the two conditions that comprise it: Crohn's disease and ulcerative colitis, both of which cause chronic inflammation of the gastrointestinal tract. World IBD Day is sponsored by the European Federation of Crohn's and Ulcerative Colitis Associations, which includes the Crohn's & Colitis Foundation.
