Article Synopsis
  • Women with inflammatory bowel disease (IBD) face challenges in reproductive health, with many not receiving adequate contraception counseling despite a high comfort level in discussing these issues with their healthcare providers.
  • A study of 338 women revealed that while 74% used contraception, long-acting methods were relatively underutilized, especially among those in remission, indicating a need for improved education on contraceptive options.
  • Key preferences for contraceptive methods included effectiveness, ease of use, and minimal side effects, emphasizing the importance of better communication and support from healthcare professionals in managing reproductive health for women with IBD.

Background: Many women of childbearing age with inflammatory bowel disease (IBD) require advanced therapies. While biologics are largely low risk during pregnancy, the novel small molecules tofacitinib, filgotinib, upadacitinib and ozanimod (TFUO) have shown concerning teratogenic effects, and decreased fertility in animal studies. Therefore, their use in women of childbearing age needs careful consideration.

Background: Acute severe ulcerative colitis (ASUC) is a potentially life-threatening medical emergency that occurs in up to 25% of patients with ulcerative colitis. Although intravenous corticosteroids remain the cornerstone of therapy, 30-40% of patients will not respond and need timely consideration of rescue therapy with (currently) either infliximab or ciclosporin or indeed colectomy, underscoring the importance of multidisciplinary care to ensure favourable outcomes for patients. We discuss the current evidence and present an approach to the management of ASUC for general and specialist clinicians caring for patients with ASUC.

The peak incidence of inflammatory bowel disease (IBD) coincides with a woman's prime reproductive years. The management of IBD during pregnancy can be challenging for healthcare professionals, underpinning the need for a multi-disciplinary approach with shared decision-making with the patient. Pre-conception counselling can address patient concerns, improve pregnancy specific IBD patient knowledge and provide a personalized risk assessment, to ensure optimal maternal and fetal outcomes.

Ulcerative colitis (UC) is a chronic, relapsing-and-remitting, potentially progressive form of inflammatory bowel disease (IBD) with multidimensional and often negative effects on patients' lives. Fecal urgency, the sudden and compelling desire to defecate, often accompanied by impaired bowel control leading to frequent and urgent trips to the bathroom, is a distressing symptom, experienced by more than 50% of patients with UC. Physicians frequently underestimate the burden of fecal urgency on patients' lives, with ramifications ranging from disruption in daily activities, social interactions, and emotional distress with resultant impairment in quality of life (QoL).

Article Synopsis
  • - This study assessed the effectiveness of various biologic therapies for inflammatory bowel disease (IBD) using real-world data from a large UK patient cohort over a significant period.
  • - Results showed that vedolizumab (VDZ) was more effective than anti-TNF agents for ulcerative colitis, particularly after previous treatments failed, and that infliximab (IFX) outperformed adalimumab (ADA) for Crohn's disease.
  • - The findings suggest that switching to a non-anti-TNF biologic after failure of the first anti-TNF treatment yields better outcomes, challenging existing treatment guidelines.

Objective: Despite its association with poorer outcomes, opioid use in inflammatory bowel disease (IBD) is not well characterised in the UK. We aimed to examine the extent of opioid use, the associated factors and the use of mitigation techniques such as pain-service review and opioid weaning plans among individuals with IBD.

Methods: Data were collected from consecutive patients attending IBD outpatient appointments at 12 UK hospitals.

Background And Aims: Despite intravenous (IV) vedolizumab being established for treatment of inflammatory bowel disease (IBD), the novel subcutaneous (SC) route of administration may provide numerous incentives to switch. However, large-scale real-world data regarding the long-term safety and effectiveness of this strategy are lacking.

Methods: IBD patients on IV vedolizumab across 11 UK sites agreed to transition to SC injections or otherwise continued IV treatment.

Background And Aims: Healthcare quality improvement (QI) is the systematic process to continuously improve the quality of care and outcomes for patients. The landmark Inflammatory Bowel Disease (IBD) UK National Audits provided a means to measure the variation in care, highlighting the need to define the standards of excellence in IBD care. Through a consensus approach, we aimed to establish key performance indicators (KPIs), providing reliable benchmarks for IBD care delivery in UK.

Background And Aims: Inflammatory bowel disease colitis-associated dysplasia is managed with either enhanced surveillance and endoscopic resection or prophylactic surgery. The rate of progression to cancer after a dysplasia diagnosis remains uncertain in many cases and patients have high thresholds for accepting proctocolectomy. Individualised discussion of management options is encouraged to take place between patients and their multidisciplinary teams for best outcomes.
