The article discusses the lack of association of the pregnane X receptor gene with inflammatory bowel disease determined through a parallel allelic association study and gene wide haplotype analysis. According to sources, dysregulation of this gene may influence intestinal barrier defence and susceptibility to inflammatory bowel disease. Thus, a critical re-evaluation of the allelic variants of the gene as determinants of disease susceptibility and phenotype in the Scottish population.

A case study of a 39-year-old female smoker presented to the gastrointestinal unit with a 6-month history of increasing right upper quadrant pain, abdominal distension, nausea and anorexia is presented. The patient has a history of dysmenorrhea but no bowel disturbance. It has found that the abdomen was distended with right upper quadrant tenderness. Investigations showed a normal full blood count and normal renal and liver biochemistry.

Objective: Management of acute severe UC (ASUC) during the novel COVID-19 pandemic presents significant dilemmas. We aimed to provide COVID-19-specific guidance using current British Society of Gastroenterology (BSG) guidelines as a reference point., Design: We convened a RAND appropriateness panel comprising 14 gastroenterologists and an IBD nurse consultant supplemented by surgical and COVID-19 experts. Panellists rated the appropriateness of interventions for ASUC in the context of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Median scores and disagreement index (DI) were calculated. Results were discussed at a moderated meeting prior to a second survey., Results: Panellists recommended that patients with ASUC should be isolated throughout their hospital stay and should have a SARS-CoV-2 swab performed on admission. Patients with a positive swab should be discussed with COVID-19 specialists. As per BSG guidance, intravenous hydrocortisone was considered appropriate as initial management; only in patients with COVID-19 pneumonia was its use deemed uncertain. In patients requiring rescue therapy, infliximab with continuing steroids was recommended. Delaying colectomy because of COVID-19 was deemed inappropriate. Steroid tapering as per BSG guidance was deemed appropriate for all patients apart from those with COVID-19 pneumonia in whom a 4-6 week taper was preferred. Post-ASUC maintenance therapy was dependent on SARS-CoV-2 status but, in general, biologics were more likely to be deemed appropriate than azathioprine or tofacitinib. Panellists deemed prophylactic anticoagulation postdischarge to be appropriate in patients with a positive SARS-CoV-2 swab., Conclusion: We have suggested COVID-19-specific adaptations to the BSG ASUC guideline using a RAND panel., (© Author(s) (or their employer(s)) 2020.

The COVID-19 pandemic is putting unprecedented pressures on healthcare systems globally. Early insights have been made possible by rapid sharing of data from China and Italy. In the UK, we have rapidly mobilised inflammatory bowel disease (IBD) centres in order that preparations can be made to protect our patients and the clinical services they rely on. This is a novel coronavirus; much is unknown as to how it will affect people with IBD. We also lack information about the impact of different immunosuppressive medications. To address this uncertainty, the British Society of Gastroenterology (BSG) COVID-19 IBD Working Group has used the best available data and expert opinion to generate a risk grid that groups patients into highest, moderate and lowest risk categories. This grid allows patients to be instructed to follow the UK government's advice for shielding, stringent and standard advice regarding social distancing, respectively. Further considerations are given to service provision, medical and surgical therapy, endoscopy, imaging and clinical trials., Competing Interests: Competing interests: For details of conflicts of interest see online supplementary table 1., (© Author(s) (or their employer(s)) 2020.

The management of inflammatory bowel disease represents a key component of clinical practice for members of the British Society of Gastroenterology (BSG). There has been considerable progress in management strategies affecting all aspects of clinical care since the publication of previous BSG guidelines in 2004, necessitating the present revision. Key components of the present document worthy of attention as having been subject to re-assessment, and revision, and having direct impact on practice include: The data generated by the nationwide audits of inflammatory bowel disease (IBD) management in the UK in 2006, and 2008. The publication of 'Quality Care: service standards for the healthcare of people with IBD' in 2009. The introduction of the Montreal classification for Crohn's disease and ulcerative colitis. The revision of recommendations for the use of immunosuppressive therapy. The detailed analysis, guidelines and recommendations for the safe and appropriate use of biological therapies in Crohn's disease and ulcerative colitis. The reassessment of the role of surgery in disease management, with emphasis on the importance of multi-disciplinary decision-making in complex cases. The availablity of new data on the role of reconstructive surgery in ulcerative colitis. The cross-referencing to revised guidelines for colonoscopic surveillance, for the management of metabolic bone disease, and for the care of children with inflammatory bowel disease.
