Patients with colonic inflammatory bowel disease (IBD) have a high risk of colorectal cancer (CRC). Current guidelines recommend endoscopic surveillance, yet epidemiological studies show poor compliance. The aims our study were to analyse adherence its impact on advanced lesions, and factors non-adherence.A retrospective multicentre IBD patients criteria for CRC diagnosed between 2005 2008 followed up 2020, was performed. Following European guidelines, stratified into groups considered when...

Summary Background Ulcerative proctitis (UP) can have a milder, less aggressive course than left‐sided colitis or extensive colitis. Therefore, immunosuppressants tend to be used in patients with this condition. Evidence, however, is scarce because these are excluded from randomised controlled clinical trials. Our aim was describe the characteristics of refractory UP and their disease‐related complications, identify need for immunosuppressive therapies. Methods We identified prospective...

Inflammatory bowel disease (IBD) is associated with a considerable burden to the patient and society. However, current data on IBD incidence are limited because of paucity nationwide epidemiological studies, heterogeneous designs, low number participating centers sample size. The EpidemIBD study large-scale investigation provide an accurate assessment in Spain, as well treatment patterns outcomes.This multicenter, population-based cohort included patients aged >18 years (Crohn's disease,...

Argon plasma coagulation (APC) is a noncontact technique of electrocoagulation in which energy transmitted via ionized argon gas flow. The tip the catheter should be kept between 1 mm and 3 away from mucosa. APC has become increasingly popular for treating gastric antral vascular ectasia (GAVE). Its main advantage that more superficial, thus reducing risk complications [1].

Abstract Background The prevalence of hepatitis C virus infection (HCV) in patients with inflammatory bowel disease (IBD) ranges from 1–6%. Direct-acting antivirals (DAAs), cure rates &amp;gt;90%, represent a radical change interferon-based therapies. ECCO guidelines (Kucharzik JCC 2021) warns about the risk IBD reactivation due to effect DAAs, but HCV management this situation is uncertain given lack evidence. AIMS: To evaluate: 1) Effectiveness and safety DAAs IBD; 2) Interaction drugs,...

Background: Infliximab seems to be the most efficacious of three available anti-TNF agents for ulcerative colitis (UC) but little is known when it used as second anti-TNF. Objectives: To compare clinical and treatment outcomes a subcutaneous or intravenous in UC patients. Design: Retrospective observational study. Methods: Patients from ENEIDA registry treated consecutively with infliximab (or vice versa), naïve other biological agents, were identified grouped according administration route...

Abstract Background Anti-TNF drugs have proven effective in managing Inflammatory Bowel Disease (IBD), but a significant percentage of patients exhibit primary or secondary non-response. Therapeutic drug monitoring (TDM) is valuable tool for optimizing patient management. HLA-DQA1*05 gene has been investigated as potential marker immunogenicity and loss response to anti-TNF therapy.This prospective, multicentric study aimed assess the clinical impact determining Adalimumab (ADA) levels...

Randomised clinical trials have confirmed that biological therapy with anti-tumour necrosis factor (anti-TNF) agents is an effective treatment to induce remission as well avoid hospitalisation and colectomy in ulcerative colitis (UC). Infliximab (IFX) Adalimumab (ADA) are available for UC, Spain, since 2009 2012, respectively. Aim: assess the long-term effectiveness of anti-TNF UC a real-world setting. A retrospective multicentre cohort study was performed on patients receiving between 2015,...

Abstract Background Some patients with Inflammatory Bowel Disease (IBD) who are treated anti-TNFα therapy develop a drug-induced psoriasis (IP) as an adverse event. There some therapeutic approaches, being more frequent to change the biologic ustekinumab, effective and approved for treatment of both entities. This could be best option, but available data lacking it increase risk IBD relapse. Our aim is assess management anti-TNF IP in IBD, subsequent evolution diseases large nationwide...
