Ten missteps in the management of inflammatory bowel disease in Asia: An expert report by the Asian Pacific Association of Gastroenterology Working Group on Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is rapidly emerging in the Asia Pacific region. However, there are many challenges in the diagnosis and management of this condition. The Asian Pacific Association of Gastroenterology (APAGE) Working Group on IBD conducted a round table meeting to identify 10 common mistakes in the management of IBD in Asia. To summarize, many physicians still over rely on a definitive histological diagnosis before starting treatment and do not fully establish disease extent such as perianal and proximal gastrointestinal involvement in Crohn's disease (CD) or extent of involvement in ulcerative colitis (UC). It is also essential to actively look for evidence of extra-intestinal manifestations, which may influence choice of therapy. In terms of conventional therapy, underuse of topical 5 aminosalicylates (5-ASAs) in UC and inappropriate dosing of corticosteroids are also important considerations. Acute severe UC remains a life-threatening condition and delay in starting rescue therapy after inadequate response to intravenous steroids is still common. Anti-tumor necrosis factors should be considered first line in all cases of complex perianal fistulizing CD. Most patients with IBD are on potent immunosuppressive therapy and should be screened for latent infections and offered vaccinations according to guidelines. Under-recognition and management of significant complications such as anemia, osteoporosis, malnutrition, and thromboembolism should also be addressed. Colonoscopy is still not properly performed for dysplasia/cancer surveillance and for evaluating post-op recurrence of CD. Another common misstep is inappropriate withdrawal of medications during pregnancy leading to increased complications for the mother and the newborn.

Effects of Thiopurine Withdrawal on Vedolizumab-Treated Patients With Ulcerative Colitis: a Randomized Controlled Trial.

BACKGROUND AND AIMS: The impact of thiopurine de-escalation whilst on vedolizumab versus continuing thiopurine therapy in ulcerative colitis (UC) is unclear. We aimed to determine the effect of thiopurine withdrawal for patients with UC in remission on vedolizumab. METHODS: This multi-centre randomized controlled trial recruited UC patients on vedolizumab 300mg IV every 8 weeks and a thiopurine. Patients in steroid-free clinical remission for ≥6 months and endoscopic remission/improvement (Mayo endoscopic subscore[MES]≤1) were randomized 2:1 to withdraw or continue thiopurine. Primary outcome was comparing week 48 vedolizumab trough concentrations. Secondary outcomes were clinical relapse (partial Mayo score≥3 and fecal calprotectin>150µg/g or increase in MES≥1 from baseline), fecal calprotectin remission (<150µg/g), C-reactive protein remission (<5mg/L), centrally-read endoscopic remission (MES=0), histologic remission (Nancy index=0), histo-endoscopic remission and adverse events. RESULTS: In total, 62 patients were randomized to continue (n=20) or withdraw (n=42) thiopurine. At week 48, vedolizumab trough concentrations were not significantly different between continue and withdrawal groups (14.7µg/mL [IQR:12.3-18.5µg/mL] versus 15.9µg/mL [IQR:10.1-22.7µg/mL] respectively, P=0.36). The continue group had significantly higher fecal calprotectin remission (95.0% [19/20] versus 71.4% [30/42], P=0.03), histologic remission (80.0% [16/20] versus 48.6% [18/37], P=0.02) and histo-endoscopic remission (75.0% [15/20] versus 32.4% [12/37], P=0.002) than the withdrawal group. Histological activity (HR:15.5 [95%CI:1.6-146.5],P=0.02) and prior anti-TNF exposure (HR:6.5 [95%CI:1.3-33.8],P=0.03) predicted clinical relapse after thiopurine withdrawal. CONCLUSION: Thiopurine withdrawal did not affect vedolizumab trough concentrations. However, it may increase fecal calprotectin, histologic and histo-endoscopic activity. Histological activity and prior anti-TNF exposure may predict disease relapse upon thiopurine withdrawal for patients using vedolizumab for UC; Australian and New Zealand Trial Registry, number ACTRN12618000812291.

Meta-analysis: Persistence of advanced therapies in the treatment of inflammatory bowel disease.

BACKGROUND: The expanding options in advanced therapies for ulcerative colitis (UC) and Crohn's disease (CD) present challenges in treatment selection. Persistence analysis assesses drug durability in real-world settings, acting as a surrogate marker for medication efficacy and tolerance. Unlike traditional comparative studies, persistence analysis provides insights extending beyond the initial year of treatment. AIM: To provide real-world evidence on treatment effectiveness, tolerability and preferences of physicians and patients regarding various advanced therapies for IBD. METHODS: We conducted a systematic review of observational studies up to March 2023 assessing advanced therapies' persistence in UC and CD. Advanced therapies under examination included infliximab, adalimumab, vedolizumab, ustekinumab, golimumab, certolizumab and tofacitinib. We pooled the persistence of each agent and conducted a meta-analysis to compare the persistence of newer agents with traditional TNF inhibitors (TNFi)-specifically infliximab and adalimumab. RESULTS: Among 63 observational studies, vedolizumab had the highest 1-year persistence in UC (73.8%, 95% CI: 70.0%-77.6%) and ustekinumab in CD (77.5%, 95% CI: 72.9%-82.1%). Compared to TNFi, vedolizumab demonstrated increased persistence with a relative risk (RR) of 1.30 (95% CI: 1.19-1.41) for UC and 1.14 (95% CI: 1.09-1.20) for CD at 1 year, while ustekinumab demonstrated a RR of 1.15 (95% CI: 1.07-1.23) for CD at 1 year. Vedolizumab exhibited sustained increased persistence in UC over 2 years compared to TNFi (RR: 1.33, 95% CI 1.14-1.54). CONCLUSION: This meta-analysis highlights the superior persistence of ustekinumab and vedolizumab over TNFi, and offers valuable insights for clinicians navigating the challenging landscape of UC and CD therapeutic choices.

Intravenous Versus Subcutaneous Infliximab in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.

BACKGROUND: Subcutaneous (SC) infliximab may provide multiple benefits over intravenous (IV) formulations. However, studies for efficacy and safety in inflammatory bowel disease (IBD) have been constrained by small sizes that limit the interpretation of outcomes, especially for subgroups potentially at high-risk of disease relapse. METHODS: We conducted a systematic review and random-effects meta-analysis up to January 2023 to evaluate the change in clinical remission after transitioning from IV to SC infliximab in patients with IBD in clinical remission. The primary outcome was measured using the relative risk for meta-analysis. RESULTS: 15 studies of patients established ≥3 months on IV infliximab were identified, consisting of 1371 patients and 840 patient-years of follow-up. There was no loss of clinical remission in the IBD cohort overall, Crohn's disease (CD), and perianal CD p=0.55 & p=0.11 at 9-12 months, and p=0.50 at 6 months respectively). Neither prior IV dose (≤10mg/kg 6-weekly) (p=0.48) nor IBD disease subtype was associated with an increased clinical relapse rate at 6 months (p=0.48 and p=0.45 (UC vs CD), respectively). CONCLUSION: Changing patients established on IV infliximab to an SC formulation is associated with a high ongoing clinical remission and low adverse event rate. Furthermore, there are no signals for adverse outcomes among different IBD disease subtypes, nor in those on escalated IV infliximab dosing schedules up to 10mg/kg 6-weekly. This data should provide patients and clinicians alike with confidence in SC infliximab use in IBD.

Biological Agents in the Treatment of Crohn's Disease: A Propensity Score-Matched Analysis From the Prospective Persistence Australian National IBD Cohort (PANIC3) Study.

INTRODUCTION: Comparative effectiveness research provides data on the relative benefits and risks between treatments. In Crohn's disease (CD), however, there are few head-to-head studies comparing advanced therapies and none with long-term follow-up. Real-world effectiveness, defined by treatment persistence, obtained from prospective population-based patient cohorts, may help determine the best sequencing and positioning of biological agents. METHODS: We analyzed the prospectively collected population-based Australian national Pharmaceutical Benefits Scheme dispensing data registry (2005-2019) for CD. There is no mandated biological agent prescribing order, and all citizens and permanent residents are eligible for treatment irrespective of insurance status. Propensity score matching was performed to reduce selection bias. RESULTS: There were 2,029 lines of therapy in 1,446 patients (median age 43 years, interquartile range 34-58, 44% male patients) over the 15-year period with 5,618 patient-years of follow-up. Per line of therapy, 915/2,029 (45.1%) patients used adalimumab, 722/2,029 (35.6%) used infliximab, 155/2,029 (7.6%) used vedolizumab, and 237/2,029 (11.7%) used ustekinumab. When used in biological agent-naive patients, there was no difference in persistence between any agent ( P > 0.05). Used after first line in biological agent-experienced CD, ustekinumab had significantly better persistence than non-ustekinumab biological agents ( P = 0.0018), vs anti-tumor necrosis factor (TNF) alpha therapy ( P = 0.006) or vedolizumab ( P < 0.001). Ustekinumab persistence was unaffected by prior biological agent exposure ( P = 0.51). After anti-TNF use, ustekinumab had superior persistence to an alternative anti-TNF agent ( P = 0.033) and to vedolizumab ( P = 0.026). Using a propensity score-matched analysis adjusted for age, immunomodulator use, and bio-exposed status, ustekinumab had superior persistence to anti-TNF ( P = 0.01). Multivariate predictors of worse persistence were the use of a non-ustekinumab biological agent (adjusted hazard ratio 2.10, P < 0.001), and bio-experienced status (adjusted hazard ratio 1.23, P < 0.001). DISCUSSION: This large national prospective database with nonhierarchical prescribing of biological agents did not identify superior persistence of any agent in bio-naive CD. However, for patients with bio-experienced CD, persistence was greater with ustekinumab.

Efficacy and Safety of Ustekinumab for Ulcerative Colitis Through 4 Years: Final Results of the UNIFI Long-Term Maintenance Study.

INTRODUCTION: Ulcerative colitis (UC) is a chronic condition that may require long-term treatment. We report the final efficacy and safety results of the UNIFI long-term extension study of ustekinumab in patients with UC through 4 years. METHODS: Ustekinumab induction responders who completed 44 weeks of maintenance treatment and agreed to enter the long-term extension continued their subcutaneous maintenance therapy (90 mg ustekinumab every 8 or 12 weeks [q8w or q12w] or placebo). Starting at week 56, randomized patients could receive dose adjustment to 90 mg q8w. Symptoms and adverse events were assessed through the study; endoscopic assessment was conducted at week 200. RESULTS: Of the 348 patients randomized to subcutaneous ustekinumab at maintenance baseline (q8w and q12w combined), 55.2% were in symptomatic remission at week 200. A greater proportion of biologic-naive patients (67.2% [117/174]) were in symptomatic remission than those with a history of biologic failure (41.6% [67/161]). Among patients in symptomatic remission at week 200, 96.4% were corticosteroid-free. Of the 171 patients with endoscopic evaluation at week 200, 81.6% (71/87) in the q12w group and 79.8% (67/84) in the q8w group had endoscopic improvement. From weeks 156 to the final safety visit (up to week 220), no deaths, major adverse cardiovascular events, or tuberculosis occurred in patients receiving ustekinumab. Nasopharyngitis, UC worsening, and upper respiratory tract infections were the most frequently reported adverse events. DISCUSSION: The long-term efficacy of ustekinumab maintenance in patients with UC was confirmed through 4 years. No new safety signals were observed. ClinicalTrials.gov number NCT02407236.

The Disease Severity Index for Inflammatory Bowel Disease Is a Valid Instrument that Predicts Complicated Disease.

BACKGROUND: The disease severity index (DSI) for inflammatory bowel disease (IBD) combines measures of disease phenotype, inflammatory activity, and patient-reported outcomes. We aimed to validate the DSI and assess its utility in predicting a complicated IBD course. METHODS: A multicenter cohort of adults with IBD was recruited. Intraclass correlation coefficients (ICCs) and weighted Kappa assessed inter-rater reliability. Cronbach's alpha measured internal consistency of DSI items. Spearman's rank correlations compared the DSI with endoscopic indices, symptom indices, quality of life, and disability. A subgroup was followed for 24 months to assess for a complicated IBD course. Area under the receiver operating characteristics curve (AUROC) and multivariable logistic regression assessed the utility of the DSI in predicting disease progression. RESULTS: Three hundred and sixty-nine participants were included (Crohn's disease [CD], n = 230; female, n = 194; mean age, 46 years [SD, 15]; median disease duration, 11 years [interquartile range, 5-21]), of which 171 (CD, n = 99; ulcerative colitis [UC], n = 72) were followed prospectively. The DSI showed inter-rater reliability for CD (ICC 0.93, n = 65) and UC (ICC 0.97, n = 33). The DSI items demonstrated inter-rater agreement (Kappa > 0.4) and internal consistency (CD, α > 0.59; UC, α > 0.75). The DSI was significantly associated with endoscopic activity (CDn=141, r = 0.65, P < .001; UCn=105, r = 0.80, P < .001), symptoms (CDn=159, r = 0.69, P < .001; UCn=132, r = 0.58, P < .001), quality of life (CDn=198, r = -0.59, P < .001; UCn=128, r = -0.68, P < .001), and disability (CDn=83, r = -0.67, P < .001; UCn=52, r = -0.74, P < .001). A DSI of 23 best predicted a complicated IBD course (AUROC = 0.82, P < .001) and was associated with this end point on multivariable analyses (aOR, 9.20; 95% confidence interval, 3.32-25.49). CONCLUSIONS: The DSI reliably encapsulates factors contributing to disease severity and accurately prognosticates the longitudinal IBD course.

This study shows that the disease severity index (DSI) for inflammatory bowel disease (IBD) is a valid and reliable instrument encapsulating the disease phenotype, disease activity, and impact of the disease on the patient; and it accurately predicts for incident disease complications.

Comparing persistence of new biologics to conventional anti-TNF alphas in adult patients with inflammatory bowel disease: a systematic review and meta-analysis protocol.

BACKGROUND: Biological therapy is a cornerstone of managing moderate-to-severe inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD). New biologics have been evolving over the past 20 years and selection of an agent remains challenging.Drug persistence measures the duration of time from initiation to discontinuation of a therapy, which can be a surrogate marker of drug tolerance and efficacy. OBJECTIVES: The study aimed to compare drug persistence of new generation biologics for the treatment of UC and CD (vedolizumab, ustekinumab, certolizumab, tofacitinib, natalizumab and golimumab) with conventional anti-tumor necroisis factor alphas (anti-TNF alphas) (adalimumab and infliximab) in adult patients with IBD. Results of the study may provide guidance on the preferred first and subsequent lines of biological treatments in patients with IBD. METHODS AND ANALYSIS: Search via electronic databases including EMBASE, MEDLINE, PubMed and clinical trial databases will be conducted on 10 March 2023 with eligible studies included from inception of 2017 to 2023. The primary outcomes are 1-year persistence of individual biologics with comparison of new biologics versus conventional anti-TNF alphas. A meta-analysis will be conducted using Review Manager V.5 and outcome will be presented as relative risk. Heterogeneity will be assessed with forest plot, χ2 and I2, followed with sensitivity analysis and subgroup analysis. Finally, the Grading of Recommendations Assessment, Development and Evaluation system will be used to assess the quality of evidence. ETHICS AND DISSEMINATION: Ethical approval is not required as no private information of participants will be used. Results of the present study will be disseminated in a peer-reviewed journal or conference presentation. PROSPERO REGISTRATION NUMBER: CRD42023392236.

Planning to conceive within a year is associated with better pregnancy-specific disease-related patient knowledge and better medication adherence in women of childbearing age with inflammatory bowel disease.

Background: Adherence to inflammatory bowel disease (IBD) medication is crucial to maintain remission, especially during pregnancy. Objective: To examine the influence of family planning and pregnancy-related patient knowledge regarding IBD and pregnancy on adherence. Design: Cross-sectional survey study. Methods: We surveyed female patients with IBD aged 18-35 years, who at recruitment to the UK IBD BioResource had not had children. We elicited disease and treatment history, demographics and family planning status via an online questionnaire. Patient knowledge as assessed by the validated Crohn's and Colitis Pregnancy Knowledge Score (CCPKnow) and adherence by visual analogue scale (VAS). Results: In 326 responders (13.8% response rate), good adherence (VAS ⩾ 80) was found in only 38.35%. Disease- and treatment-related factors were not significantly associated with good adherence, except for methotrexate (70.0% adherent of 10 exposed patients versus 37.2% non-exposed; p = 0.036). Patients planning pregnancy for the next year were more often adherent (59.0% versus 35.5%; p = 0.019) and knowledgeable (median CCPKnow 8 versus 7; p = 0.035) compared to those in other family planning categories. Pregnancy-related patient knowledge was significantly associated with adherence (Pearson correlation 0.141; p = 0.015). Adherent patients had significantly higher CCPKnow scores than non-adherent patients (median 8 versus 6; p = 0.009). On binary regression analysis, only planning to conceive within 12 months was independently associated with better adherence (p = 0.016), but not methotrexate exposure (p = 0.076) and CCPKnow (p = 0.056). Conclusions: In a cohort of women of childbearing age with IBD overall medication, adherence was low. Planning to conceive within the next year was associated with better adherence and greater patient knowledge.

IBD barriers across the continents: a continent-specific analysis - Australasia.

Australasia, encompassing Australia, New Zealand, and Papua New Guinea, has some of the highest prevalence's of inflammatory bowel disease (IBD) in the world. The way IBD medicine is practiced varies between and within these countries. There are numerous shared issues of IBD care between Australia and New Zealand, whereas Papua New Guinea has its' own unique set of circumstances. This review looks to explore some of the barriers to IBD care across the continent from the perspective of local IBD healthcare professionals. Barriers to IBD care that are explored include access to IBD multidisciplinary teams, provision of nutritional-based therapies, the prevalence and engagement of IBD-associated mental health disorders, access to medicine, access to endoscopy, rural barriers to care, Indigenous IBD care and paediatric issues. We look to highlight areas where improvements to IBD care across Australasia could be made as well as address research needs.

Real-world experience with subcutaneous infliximab: broadening treatment strategies for inflammatory bowel disease.

INTRODUCTION: The first subcutaneous (SC) formulation of infliximab (IFX), CT­P13 SC, has been approved in Europe and Australia, including for the treatment of inflammatory bowel disease (IBD). AREAS COVERED: We provide a comprehensive overview of available clinical trial and real-world data for IFX SC treatment of IBD, focusing on the potential benefits of switching from IFX intravenous (IV) to IFX SC. We evaluate emerging evidence for IFX SC treatment for difficult-to-treat IBD, use as monotherapy, and suitability for patients receiving escalated IFX IV doses. Therapeutic drug monitoring approaches and patient and healthcare system perspectives on IFX SC are also discussed. EXPERT OPINION: IFX SC represents a significant treatment innovation in the tumor necrosis factor inhibitor class after approximately 20 years of IFX IV availability. Evidence suggests that IFX SC is well tolerated and is associated with high patient acceptance and satisfaction. In addition, effectiveness is maintained in patients with stable disease following switch from IFX IV. Switching may be advisable, given the clinical benefits of IFX SC and its potential to improve healthcare service capacity. There are several areas requiring further research, including the role of IFX SC in difficult-to-treat and refractory disease, and the feasibility of IFX SC monotherapy.

Adalimumab originator versus adalimumab biosimilars in inflammatory bowel disease in Australia.

BACKGROUND: Biosimilar adalimumabs have improved treatment access, but without any clinical advantage, distributors rely on delivery device design-enhancements, support services, and removal of painful excipients to capture market share. Prescribers, however, are often unaware of these differences. This article compares and contrasts originator versus biosimilar adalimumab agents to identify key differences that might influence adalimumab selection. RESEARCH DESIGN AND METHODS: We reviewed listed adalimumab biosimilars in Australia and compared them to the originator adalimumab. Similarities and differences identified were confirmed with the manufacturers via two rounds of interviews: the first to collate a list of features and benefits of their product, and the second to consolidate and confirm the data. RESULTS: The originator adalimumab Humira [by AbbVie, U.S.A] and four adalimumab biosimilars (Amgevita [by Amgen, U.S.A], Hadlima [by Organon, U.S.A], Hyrimoz [by Sandoz, Switzerland], and Idacio [by Fresenius Kabi, Germany]) are included in this review. Key differences identified include product formulation, dosages available, delivery devices, physician support, patient support, and the supply of other biosimilar products by the company. CONCLUSION: Adalimumab biosimilars are different from each other with unique advantages and disadvantages likely to influence prescriber and patients. Therefore, the choice of agent should be individualized to the needs of the patient and the healthcare service.

Australian inflammatory bowel disease consensus statements for preconception, pregnancy and breast feeding.

OBJECTIVE: Because pregnancy outcomes tend to be worse in women with inflammatory bowel disease (IBD) than in those without, we aimed to update consensus statements that guide the clinical management of pregnancy in patients with IBD. DESIGN: A multidisciplinary working group was established to formulate these consensus statements. A modified RAND/UCLA appropriateness method was used, consisting of a literature review, online voting, discussion meeting and a second round of voting. The overall agreement among the delegates and appropriateness of the statement are reported. RESULTS: Agreement was reached for 38/39 statements which provide guidance on management of pregnancy in patients with IBD. Most medications can and should be continued throughout pregnancy, except for methotrexate, allopurinol and new small molecules, such as tofacitinib. Due to limited data, no conclusion was reached on the use of tioguanine during pregnancy. Achieving and maintaining IBD remission before conception and throughout pregnancy is crucial to optimise maternofetal outcomes. This requires a multidisciplinary approach to engage patients, allay anxieties and maximise adherence tomedication. Intestinal ultrasound can be used for disease monitoring during pregnancy, and flexible sigmoidoscopy or MRI where clinically necessary. CONCLUSION: These consensus statements provide up-to-date, comprehensive recommendations for the management of pregnancy in patients with IBD. This will enable a high standard of care for patients with IBD across all clinical settings.

Knowledge and attitudes towards the use of histological assessments in ulcerative colitis by gastroenterologists vs pathologists.

BACKGROUND: Histological remission is increasingly accepted as a treatment endpoint in the management of ulcerative colitis (UC). However, the knowledge of histology guidelines and the attitudes towards their use in clinical practice by gastroenterologists and pathologists is unknown. AIM: To evaluate the knowledge of histology guidelines and attitudes towards the use of histology in UC by gastroenterologists and pathologists. METHODS: A prospective, cross-sectional nationwide survey of gastroenterologists and pathologists who analyse UC specimens was conducted. The survey consisted of 34 questions to assess gastroenterologists' and pathologists' knowledge (score out of 19) and attitudes towards histological assessment in UC. Survey questions were formulated using the European Crohn's and Colitis position paper on histopathology and the British Society of Gastroenterology biopsy reporting guidelines. It included knowledge of histological assessment of disease activity and dysplasia, knowledge of histological scoring systems for ulcerative colitis, uptake of histology scoring systems in routine practice, attitudes towards the role of histological activity, and the use of histological activity in clinical scenarios. RESULTS: Of 89 responders (77 gastroenterologists, 12 pathologists), there was almost universal acceptance that histological assessment should form part of UC evaluation [95% gastroenterologists, 92% pathologists]. However, gastroenterologists reported that 92% of their pathologists do not use a histological scoring system. Utilisation of a formal histological scoring system was preferred by 77% of gastroenterologists and 58% of pathologists. Both groups lacked awareness of the Geboes Score, Nancy Index and Robarts Histopathological Index scoring systems with 91%, 87%, and 92% of gastroenterologists respectively; and 83%, 83%, and 92% pathologists respectively, being uncertain of scoring systems' remission definitions. Histology knowledge score was not significantly different between gastroenterologists and pathologists [9/19 (IQR: 8-11) vs 8/19 (IQR: 7-10), P = 0.54]. Higher knowledge scores were predicted by hospital attending gastroenterologists (P = 0.004), participation in inflammatory bowel disease (IBD) multidisciplinary teams (P = 0.009), and self-declared IBD sub-specialist (P = 0.03). CONCLUSION: Histological remission is a recognised target for both gastroenterologists and pathologists. Despite this, knowledge of histological scoring systems and their utilisation is poor.

Faecal microbiota transplantation for recurrent C. difficile infections: challenges and improvement opportunities for clinical practice and healthcare systems.

BACKGROUND: There is growing interest in faecal microbiota transplantation (FMT) as a treatment for recurrent Clostridioides difficile infection (CDI), but evidence on the diverse requirements for safe, effective and accessible services is fragmented and limited. AIMS: To identify key components of FMT provision relating to the patient care pathway, stool donor pathway and wider healthcare system, and to explore variation in practice METHODS: We conducted a narrative review of the literature and consultations with key clinical experts in the field. Evidence is drawn from high-income country contexts, with an emphasis on Australia, Canada, Italy and the United Kingdom as case example countries. RESULTS: We identify and discuss key challenges to do with healthcare capacity (workforce, FMT and stool banking facilities), donors and donations, patient access and choice of FMT delivery routes, regulation, costs and reimbursement. We also identify improvement opportunities to increase awareness of FMT and referral processes, physician training, maintaining patient registries and outcome monitoring metrics, in-country regulatory harmonisation and tackling reimbursement challenges and discuss future research needs. CONCLUSION: Effectively bringing FMT to patients in a healthcare system requires much more than just the existence of a clinically effective procedure. With FMT being a potentially effective treatment option for recurrent CDI for many patients, a well-rounded understanding of how appropriate FMT capacity can be built and nurtured is important for both healthcare providers and policymakers seeking to improve patient care.

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.
