Pregnancy outcomes among women with inflammatory bowel disease: A UK tertiary centre experience.

BACKGROUND: Optimal management of inflammatory bowel disease (IBD) in pregnancy is associated with better pregnancy outcomes. We describe management of IBD during pregnancy and maternal and fetal outcomes of patients from a tertiary UK IBD centre. METHODS: This is a retrospective observational cohort study of all pregnancies occurring between 2015 and 2021 in a large tertiary IBD centre in the UK. IBD activity and management prior to, during and after pregnancy were recorded along with pregnancy and neonatal outcomes. Associations between IBD-focused interventions and any adverse pregnancy outcomes, as well as the association between IBD severity and treatments and adverse maternofetal outcomes were assessed. RESULTS: Pregnancies in 130 women with IBD were included for analysis. The mean maternal age at delivery was 30.5 (± 4.7) years. At conception, 73 women (56.2%) were in clinical remission and 24 (18.4%) were treated with a biologic agent. Active disease during pregnancy, measured by physician global assessment, was less frequent in women who were in clinical remission at conception, compared to those not in remission at conception (16/73 21.9% vs. 39/49 79.6%; data insufficient for eight women). Active IBD at conception was associated with pre-term birth (p = 0.04). Maternal corticosteroid use in any trimester was associated with low birth weight (T1 p = 0.02; T2 p = 0.005; T3 p = 0.007). Active disease (p = 0.008) and steroid use in the third trimester (p = 0.05) were both associated with neonatal infections up to six months after birth. CONCLUSION: Women in clinical remission at the time of conception have favorable outcomes, consistent with prospective observational studies. Our observations emphasize the importance of high quality IBD care for women pre and post-partum in line with international recommendations.

Comparative Safety and Effectiveness of Ustekinumab and Anti-TNF in Elderly Crohn's Disease Patients.

BACKGROUND: Biologic therapies are associated with increased infection risk among elderly patients with inflammatory bowel disease (IBD). However, there are few data on the safety and effectiveness of ustekinumab compared with anti-tumor necrosis factor (anti-TNF) agents in the elderly. METHODS: The study sought to compare the safety and effectiveness of ustekinumab and anti-TNF agents in elderly Crohn's disease (CD) patients. Patients ≥60 years of age who commenced ustekinumab or an anti-TNF agent for CD were included in this retrospective multicenter cohort. The primary outcome was incidence of serious infections requiring hospitalization. Effectiveness was assessed by clinical remission, clinical response, and treatment persistence rates at 6 months. We adjusted for confounders using inverse probability of treatment weighting (IPTW) and performed a logistic regression analysis to assess factors associated with serious infections, clinical remission, and treatment persistence. RESULTS: Eighty-three patients commencing ustekinumab and 124 commencing anti-TNF therapy were included. There was no difference in serious infection rates between anti-TNF agents (2.8%) and ustekinumab (3.1%) (P = .924) after propensity adjustment. Clinical remission rates were comparable at 6 months for ustekinumab (55.9%) and anti-TNF agents (52.4%) (P = .762). There was a significant reduction in HBI at 6 months in both groups. Treatment persistence was comparable between ustekinumab (90.6%) and anti-TNF agents (90.0%) at 6 months. Cox regression analysis did not show differences in treatment persistence (hazard ratio, 1.23; 95% confidence interval, 0.57-2.61; P = .594) and serious infection incidence (hazard ratio, 1.38; 95% confidence interval, 0.25-7.57; P = .709) by 6 months. CONCLUSIONS: We observed comparable safety and effectiveness for ustekinumab and anti-TNF agents in treating elderly CD patients.

In this retrospective multicenter cohort study, we report equal safety and effectiveness for ustekinumab and anti-tumor necrosis factor agents in treating older adults with Crohn's disease over a 6-month period.

Management of acute severe ulcerative colitis-an update for generalist and specialist clinicians.

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. SOURCES OF DATA: The information in this review is derived from data published in peer- reviewed academic journals and registered clinical trials. AREAS OF AGREEMENT: Management of acute severe colitis requires a multidisciplinary approach with early initiation with steroids and timely escalation of treatment to either medical rescue therapy or surgery. AREAS OF CONTROVERSY: Balancing the risks of delayed surgery vs. optimizing medical therapy, including accelerated dosing schedules for biologics, remains ambiguous. GROWING POINTS: The position on newer molecules like Janus Kinase inhibitors, such as tofacitinib, is a growing area with early real-world data showing promise for steroid refractory ASUC. AREAS TIMELY FOR DEVELOPING RESEARCH: Developing predictive biomarkers and clinical risk scores for personalized rescue therapy selection is an evolving area of research.

Conception, pregnancy and inflammatory bowel disease-Current concepts for the practising clinician.

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. Most women with IBD have fertility rates comparable with the general population, although voluntary childlessness is common among women with IBD. IBD disease activity at conception and during pregnancy is a key determinant of the course of IBD during pregnancy. Active IBD during pregnancy is associated with adverse pregnancy-related outcomes, including spontaneous abortion, small for gestational age baby and preterm birth, emphasizing the importance of ensuring disease remission prior to conception. Most IBD medications (5-aminosalicylates, thiopurines if already initiated pre-conception, corticosteroids and biologic medications) are considered safe and low risk during pregnancy and breastfeeding, except for methotrexate, JAK-inhibitors, ozanimod and allopurinol and maintaining remission throughout gestation should be the priority. Most women with IBD can have a vaginal delivery, but cesarean section should be considered in active perianal disease and history of ileal pouch surgery. This narrative review outlines the current evidence for the management of IBD in pregnancy, as well as considering the pre-conceptual and post-partum period.

Attitudes, perceptions and barriers in implementing therapeutic drug monitoring for anti-TNFs in inflammatory bowel disease: a survey from the Middle East.

Background: A growing body of evidence underscores the beneficial impact of therapeutic drug monitoring (TDM) on the efficacy and cost-effectiveness of anti-tumour necrosis factor (TNF) therapy in patients with inflammatory bowel disease (IBD). Objectives: We surveyed clinician attitudes, perceptions and barriers related to TDM in IBD in the Middle East. Design: A 15-question survey was distributed through national gastroenterological societies in five Middle Eastern countries (UAE, Saudi Arabia, Kuwait, Lebanon and Egypt). Methods: Data on clinician characteristics, demographics, utilization patterns and obstacles related to the adoption of TDM with anti-TNFs were gathered. Logistic regression analysis was used to predict factors influencing the utilization of TDM. Results: Among 211 respondents (82% male), 82% were consultants, 8% were physicians with an interest in gastroenterology (GI), and 6% were GI trainees. Of these, 152 met inclusion criteria, treating >5 IBD patients per month and ⩾1 with an anti-TNF per month. TDM was used in clinical practice by 78% (95% CI: 71-85) of respondents. TDM was utilized following the loss of response (LOR) in 93%, for primary non-response (PNR) in 40% and before restarting anti-TNF therapy after a drug holiday in 33% of respondents, while 34% used TDM proactively. No specific factors were associated with the use of TDM. Barriers to TDM use included cost (85%), time lag to results (71%) and lack of insurance reimbursement (65%). Overall knowledge of TDM (70%), interpretation and actioning of results (76%) or awareness of clinical guidelines (57%) were not perceived as barriers. If barriers were removed, 95% would use TDM more frequently; 93% for LOR, 60% for PNR, 50% when restarting after a drug holiday, and 54% would use TDM proactively. Conclusion: Most gastroenterologists use TDM for LOR, with cost, time lag and insurance reimbursement being significant barriers. Addressing these barriers would increase the judicious use of reactive and proactive TDM to optimize anti-TNF therapy in IBD.

Attitudes, perceptions, and barriers in implementing therapeutic drug monitoring for anti-TNFs in inflammatory bowel disease: a survey from Middle East Anti-TNF therapies are perhaps the most widely used and available biological therapies for the treatment of inflammatory bowel disease globally even though other agents have been licensed in recent years. The role of therapeutic drug monitoring to optimise outcomes and mitigate against immunogenicity with anti-TNF agents are now being appreciated. Our study investigates clinician attitudes, perceptions, and barriers related to therapeutic drug monitoring (TDM) in the context of anti-tumor necrosis factor (TNF) therapy for inflammatory bowel disease (IBD) through a comprehensive survey distributed from five Middle Eastern countries. Among 211 respondents (82% male), 82% were consultants, 8% physicians with an interest in gastroenterology (GI), and 6% GI trainees. TDM was utilised following loss of response (LOR) in 93%, for primary non-response (PNR) in 40%, and before restarting anti-TNF therapy after a drug holiday by 33% of respondents, while 34% used TDM proactively. No specific factors were associated with the use of TDM. Barriers to TDM use included cost (85%), time lag to result (71%), and lack of insurance reimbursement (65%). Overall knowledge of TDM (70%), interpretation and actioning of results (76%), or awareness of clinical guidelines (57%) were not perceived as barriers. If barriers were removed, 95% would use TDM more frequently; 93% for LOR, 60% for PNR, 50% when restarting after a drug holiday and 54% would use TDM proactively. Most gastroenterologists use TDM for LOR, with cost, time lag, and insurance reimbursement being significant barriers. Addressing these barriers would increase judicious use of reactive and proactive TDM to optimise anti-TNF therapy in IBD.

Fecal Urgency in Ulcerative Colitis: Impact on Quality of Life and Psychological Well-Being in Active and Inactive Disease States.

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.1 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).2,3.

Biologic therapy for inflammatory bowel disease: Real-world comparative effectiveness and impact of drug sequencing in 13,222 patients within the UK IBD BioResource.

BACKGROUND AND AIMS: To compare effectiveness of different biologic therapies and sequences in patients with Inflammatory Bowel Disease (IBD) using real-world data from a large cohort with long exposure. METHODS: Demographic, disease, treatment and outcome data were retrieved for patients in the UK IBD BioResource. Effectiveness of treatment was based on persistence free of discontinuation or failure, analysed by Kaplan-Meier survival analysis with inverse probability of treatment weighting to adjust for differences between groups. RESULTS: 13,222 evaluable patients received at least one biologic. In ulcerative colitis (UC) first line vedolizumab (VDZ) demonstrated superior effectiveness over five years compared to anti-TNF agents (p=0.006). VDZ was superior to both infliximab (IFX) and adalimumab (ADA) after ADA and IFX failure respectively (p<0.001 and p<0.001). Anti-TNF therapy showed similar effectiveness when used first-line, or after failure of VDZ. In Crohn's disease (CD) we found significant differences between first line treatments over ten years (p=0.045), with superior effectiveness of IFX compared to ADA in perianal CD. Non-anti-TNF biologics were superior to a second anti-TNF after first line anti-TNF failure in CD (p=0.035). Patients with UC or CD experiencing TNF-failure due to delayed loss of response or intolerance had superior outcomes when switching to a non-anti-TNF biologic, rather than a second anti-TNF. CONCLUSIONS: We provide real-world evidence to guide biologic selection and sequencing in a range of common scenarios. Our findings challenge current guidelines regarding drug selection after loss of response to first anti-TNF.

Opioid use and associated factors in 1676 patients with inflammatory bowel disease: a multicentre quality improvement project.

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. A predefined questionnaire was used to collect data including patient demographics, IBD history, opioid use in the past year (>2 weeks) and opioid-use mitigation techniques. Additionally, consecutive IBD-related hospital stays leading up to July 2019 were reviewed with data collected regarding opioid use at admission, discharge and follow-up as well as details of the admission indication. Results: In 1352 outpatients, 12% had used opioids within the past 12 months. Over half of these individuals were taking opioids for non-IBD pain and less than half had undergone an attempted opioid wean.In 324 hospitalised patients, 27% were prescribed opioids at discharge from hospital. At 12 months postdischarge, 11% were using opioids. Factors associated with opioid use in both cohorts included female sex, Crohn's disease and previous surgery. Conclusions: 1 in 10 patients with IBD attending outpatient appointments were opioid exposed in the past year while a quarter of inpatients were discharged with opioids, and 11% continued to use opioids 12 months after discharge. IBD services should aim to identify patients exposed to opioids, reduce exposure where possible and facilitate access to alternative pain management approaches.

Establishing key performance indicators for inflammatory bowel disease in the UK.

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. Methods: KPIs that measure critical aspects of a patient journey within an IBD service were identified though stakeholder meetings. A two-stage Delphi consensus was then conducted. The first involved a multidisciplinary team of IBD clinicians and patients to refine definitions and methodology. The second stage assessed feasibility and utility of the proposed QI process by surveying gastroenterology services across UK. Results: First, the four proposed KPIs were refined and included time from primary care referral to diagnosis in secondary care, time to treatment recommendation following a diagnosis, appropriate use of steroids and advanced therapies prescreening and assessment. Second, the Delphi consensus reported >85% agreement on the feasibility of local adoption of the QI process and >75% agreement on the utility of benchmarking of the KPIs. Conclusions: Through a structured approach, we propose quantifiable KPIs for benchmarking to improve and reduce the individual variation in IBD care across the UK.

DECIDE: Delphi Expert Consensus Statement on Inflammatory Bowel Disease Dysplasia Shared Management Decision-Making.

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. We aimed to develop a toolkit to support a structured, multidisciplinary and shared decision-making approach to discussions about dysplasia management options between clinicians and their patients. METHODS: Evidence from systematic literature reviews, mixed-methods studies conducted with key stakeholders, and decision-making expert recommendations were consolidated to draft consensus statements by the DECIDE steering group. These were then subjected to an international, multidisciplinary modified electronic Delphi process until an a priori threshold of 80% agreement was achieved to establish consensus for each statement. RESULTS: In all, 31 members [15 gastroenterologists, 14 colorectal surgeons and two nurse specialists] from nine countries formed the Delphi panel. We present the 18 consensus statements generated after two iterative rounds of anonymous voting. CONCLUSIONS: By consolidating evidence for best practice using literature review and key stakeholder and decision-making expert consultation, we have developed international consensus recommendations to support health care professionals counselling patients on the management of high cancer risk colitis-associated dysplasia. The final toolkit includes clinician and patient decision aids to facilitate shared decision-making.

Management of Inflammatory Bowel Disease Using E-health Technologies: A Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: Technological advances have provided innovative, adaptive, and responsive models of care for inflammatory bowel diseases [IBD]. We conducted a systematic review to compare e-health interventions with standard care in management of IBD. METHODS: We searched electronic databases for randomised, controlled trials [RCT] comparing e-health interventions with standard care for patients with IBD. Effect measures were standardised mean difference [SMD], odds ratio [OR], or rate ratio [RR], calculated using the inverse variance or Mantel-Haenszel statistical method and random-effects models. Version 2 of the Cochrane tool was used to assess the risk of bias. The certainty of evidence was appraised with the GRADE framework. RESULTS: Fourteen RCTs [n = 3111; 1754 e-health and 1357 controls] were identified. The difference in disease activity scores (SMD 0.09, 95% confidence interval [CI]: -0.09-0.28) and clinical remission (odds ratio [OR] 1.12, 95% CI: 0.78-1.61) between e-health interventions and standard care were not statistically significant. Higher quality of life [QoL] [SMD 0.20, 95% CI: 0.05-0.35) and IBD knowledge [SMD 0.23, 95% CI: 0.10-0.36] scores were noted in the e-health group, and self-efficacy levels [SMD -0.09, 95% CI: -0.22-0.05] were comparable. E-health patients had fewer office [RR 0.85, 95% CI: 0.78-0.93] and emergency [RR 0.70, 95% CI: 0.51- 0.95] visits, with no statistically significant difference in endoscopic procedures, total health care encounters, corticosteroid use, and IBD related hospitalisation or surgery. The trials were judged to be at high risk of bias or to have some concerns for disease remission. The certainty of evidence was moderate or low. CONCLUSION: E-health technologies may have a role in value-based care in IBD.

The prevalence and burden of Rome IV faecal incontinence in ulcerative colitis: A cross-sectional study.

BACKGROUND: Despite advances in ulcerative colitis (UC) therapies, a relatively undefined proportion of patients experience faecal incontinence (FI) in the absence of active inflammation. For this group, there remains a significant unmet need with a limited evidence base. AIMS: We aimed to estimate the prevalence and impact of FI in UC. METHODS: In a prospective cross-sectional study, patients with UC completed a series of validated questionnaires, including Rome IV FI criteria, an inflammatory bowel disease (IBD)-specific FI questionnaire (ICIQ-IBD), Hospital Anxiety and Depression Scale and IBD-Control. UC remission was defined as faecal calprotectin (FCP) ≤250 µg/g, or IBD-control 8 score ≥13 and IBD-Control-VAS ≥ 85. RESULTS: Of 255 patients with UC, overall, 20.4% fulfilled Rome IV criteria for FI. Rome IV FI prevalence did not differ between active and quiescent UC regardless of whether disease activity was defined by IBD-Control scores ± FCP (p = 0.25), or objectively with FCP thresholds of 250 µg/g (p = 0.86) and 100 µg/g (p = 0.95). Most patients (75.2%) reported FI when in 'remission' and during 'relapse' (90.6%) according to ICIQ-IBD. Those who reported FI according to both ICIQ-IBD and Rome IV definitions had higher anxiety, depression and worse quality-of-life (QoL) scores (p < 0.05). In those with Rome IV FI, there was a strong correlation between FI symptom severity and impaired QoL (r = 0.809, p < 0.001). CONCLUSIONS: The prevalence of FI in UC is high, even in remission, and associated with significant psychological distress, symptom burden and impaired QoL. These findings highlight the urgent need for further research and development of evidence-based treatments for FI in UC.

The effect of immunomodulators on seroconversion after BNT162b2 and AZD1222 vaccines in patients with immune-mediated inflammatory diseases: a prospective cohort study.

BACKGROUND: Biologic and nonbiologic immunomodulators, used to treat immune-mediated inflammatory diseases (IMIDs), could impair the immune response to COVID-19 vaccines and thus vaccine effectiveness. OBJECTIVES: Our objective was to investigate the association between biologic and nonbiologic immunomodulators and seroconversion following the first and second dose of COVID-19 vaccines in patients with IMIDs. METHODS: Serum samples were collected following the first or second dose of the BNT162b2 or AZD1222 vaccines from patients receiving biologic and/or nonbiologic immunomodulators for one or more of psoriasis, psoriatic arthritis, rheumatoid arthritis, inflammatory bowel disease or systemic lupus erythematosus. Seroconversion was defined as a positive Roche Elecsys® Anti-SARS-CoV-2 S (spike protein subunit S1/receptor binding domain) immunoassay (≥ 0.8 U mL-1). Association between immunomodulator exposure and seroconversion was assessed using logistic regression, adjusting for age and sex. RESULTS: After excluding those with prior COVID-19, post-first vaccine dose samples from 193 participants and post-second dose samples from 312 participants were included in the analysis. Following the first vaccine dose, 17.6% (n = 34) of participants did not seroconvert. Seroconversion was reduced for those on nonbiologic [adjusted odds ratio (OR) 0.29, 95% confidence interval (CI) 0.12-0.69] or combined nonbiologic and biologic treatment (adjusted OR 0.14, 95% CI 0.045-0.45) compared with those on biologic monotherapy. Subgroup analysis demonstrated reduced odds of seroconversion in those on methotrexate (adjusted OR 0.097, 95% CI 0.19-0.49) or prednisolone treatment (adjusted OR 0.044, 95% CI 0.002-1.00) relative to tumour necrosis factor-α inhibitor monotherapy. No participants receiving rituximab (n < 5) seroconverted after the first vaccine dose. Following the second vaccine dose, 1.6% of all participants did not seroconvert. Non-seroconversion was associated with receiving rituximab (n = 3 of 4) compared with those receiving other therapies (n = 2 of 308, P < 0.001). Post hoc analyses demonstrated that non-seroconversion was associated with age [adjusted OR 0.18, 95% CI 0.037-0.93 for those aged 60 years and over (reference category age 18-39 years)], but not sex, ethnicity or vaccine type. CONCLUSIONS: Treatment with nonbiologics, particularly methotrexate, is associated with impaired seroconversion following two BNT162b2 or AZD1222 vaccine doses, in patients with IMIDs. These findings are consistent with those of other published studies. While this could indicate reduced protection against COVID-19, the immunological parameters that correlate most closely with vaccine effectiveness need to be defined to reach this conclusion.

Managing Inflammatory Bowel Disease in Pregnancy: Health Care Professionals' Involvement, Knowledge, and Decision Making.

BACKGROUND: The management of pregnant women with inflammatory bowel disease (IBD) is complex. We aimed to assess health care professionals' (HCPs) theoretical and applied knowledge of pregnancy-related IBD issues. METHODS: A cross-sectional international survey was distributed to HCPs providing IBD care between October 2020 and March 2021. Knowledge was assessed using the validated Crohn's and Colitis Pregnancy Knowledge Score (CCPKnow; range, 0-17). Decision-making was assessed by free text responses to 3 clinical scenarios scored against predetermined scoring criteria (maximum score 70). RESULTS: Among 81 participants, median CCPKnow score was 16 (range, 8-17), and median total scenario score was 29 (range, 9-51). Health care professionals who treat >10 IBD patients per week (CCPKnow P = .03; scenarios P = .003) and are more regularly involved in pregnancy care (CCPKnow P = .005; scenarios P = .005) had significantly better scores. Although CCPKnow scoring was consistently high (median score ≥15) across all groups, consultants scored better than trainees and IBD nurses (P = .008 and P = .031). Median scenario scores were higher for consultants (32) and IBD nurses (33) compared with trainees (24; P = .018 and P = .022). There was a significant positive correlation between caring for greater numbers of pregnant IBD patients and higher CCPKnow (P = .001, r = .358) and scenario scores (P = .001, r = .377). There was a modest correlation between CCPKnow and scenario scores (r = .356; P < 0.001). CONCLUSIONS: Despite "good" theoretical pregnancy-related IBD knowledge as assessed by CCPKnow, applied knowledge in the scenarios was less consistent. There is need for further HCP education and clinical experience to achieve optimal standardized care for IBD in pregnancy.

Objective assessment of pregnancy-specific IBD knowledge among gastroenterology health care professionals is good; however, clinician application of knowledge in decision-making is less consistent. There is need for further clinician education to provide optimal standardized care for IBD in pregnancy.

Ustekinumab and Vedolizumab Are Equally Safe and Effective in Elderly Crohn's Disease Patients.

BACKGROUND: Anti-tumour necrosis factor (anti-TNF) agents are associated with increased infection risk among elderly inflammatory bowel disease (IBD) patients, and thus, alternative biologics may be preferable. However, little comparative data exist on the safety and efficacy of vedolizumab and ustekinumab in elderly IBD patients. AIMS: To compare the safety and effectiveness of ustekinumab and vedolizumab in elderly Crohn's disease patients. METHODS: Patients ≥ 60 years old who commenced ustekinumab or vedolizumab for Crohn's disease (CD) were included. Primary outcome was serious infections, defined as requiring hospitalisation. Efficacy was assessed by treatment persistence and clinical response rates. We appropriately adjusted for confounders using propensity score-matched analysis weighted by the inverse predicted probability of treatment weighing and performed a logistic regression analysis to assess factors associated with serious infections and treatment persistence. RESULTS: Eighty-three patients commencing ustekinumab and 42 commencing vedolizumab therapy were included. In a propensity adjusted cohort, the rate of serious infection and treatment persistence were comparable between ustekinumab and vedolizumab. There was a significant reduction in HBI at 6 and 12 months compared to baseline in both groups. Male gender was positively associated with serious infection risk at 12 months, and penetrating disease behaviour was positively associated with 12-month treatment persistence. Baseline HBI score was negatively associated with 12-month treatment persistence. Cox regression analysis showed no overall difference in treatment discontinuation-free and serious infection-free survival by 12 months. CONCLUSIONS: We observed comparable safety and effectiveness for ustekinumab and vedolizumab in treating elderly CD patients.

A review of the therapeutic management of ulcerative colitis.

Ulcerative colitis (UC) is a chronic relapsing and remitting gastrointestinal disorder of uncertain aetiology. The last two decades have seen an expansion in the therapeutic arsenal used to treat UC. This has resulted in improved clinical remission and response rates. Nonetheless, staples in our current medical management originate from trials conducted in the early 20th century. In this review article, we aim to outline the key milestones in the history of the medical management of UC in addition to highlighting promising therapeutic developments for the future.
