ABSTRACT
Device assisted enteroscopy (DAE) like the double balloon enteroscopy (DBE) and single balloon enteroscopy (SBE) are postulated to ease small bowel examination and performance of therapy. However, studies comparing the effectiveness of these 2 modalities have yielded varying results. The aim of this study is to compare the efficacy and safety of SBE and DBE. We retrospectively reviewed records of patients who underwent DBE (nâ =â 82) or SBE (nâ =â 45) for small bowel exam in our unit from January 2014 to January 2022. Our primary outcomes were to compare the technical success and diagnostic success rates between DBE and SBE. Our secondary outcomes were to compare the therapeutic success, and complication rates. The main indications were suspected GI bleeding (DBE 41.5% vs SBE 48.9%), iron deficiency anemia (DBE 9.8% vs SBE 4.4%) and small bowel lesions (DBE 28.0% vs SBE 44.4%) detected either from prior capsule endoscopy or radiological imaging. Majority of the enteroscopy exam was by antegrade approach (DBE 67.1% vs SBE 77.8%). We found no significant difference in the technical success (DBE 95.1% vs SBE 97.8%, Pâ =â .46), diagnostic success (DBE 69.5% vs SBE 77.8%, Pâ =â .36) and the therapeutic success rate (DBE 63.2% vs SBE 54.3%, Pâ =â .09) between the groups. Complications occurred in 1 case from each group (mucosal tear). None of the complications were major. In patients who underwent enteroscopy, the diagnostic and therapeutic performance of SBE is similar to DBE. Both procedures were safe with low complication rates.

BACKGROUND & AIMS: The impact of thiopurine de-escalation while 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 multicenter randomized controlled trial recruited UC patients on vedolizumab 300 mg intravenously every 8 weeks and a thiopurine. Patients in steroid-free clinical remission for ≥6 months and endoscopic remission/improvement (Mayo endoscopic subscore ≤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 >150 µg/g or increase in Mayo endoscopic subscore ≥1 from baseline), fecal calprotectin remission (<150 µg/g), C-reactive protein remission (<5 mg/L), centrally read endoscopic remission (Mayo endoscopic subscore = 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 (14.7 µg/mL, interquartile rate [IQR], 12.3-18.5 µg/mL versus 15.9 µg/mL, IQR, 10.1-22.7 µg/mL, respectively, P = 0.36). The continue group had significantly higher fecal calprotectin remission (95.0%, 19/20 versus 71.4%, 30/42; P = .03), histologic remission (80.0%, 16/20 versus 48.6%, 18/37; P = .02), and histo-endoscopic remission (75.0%, 15/20 versus 32.4%, 12/37; P = .002) than the withdrawal group. Histologic activity (hazard ratio [HR], 15.5; 95% confidence interval [CI], 1.6-146.5; P = .02) and prior anti-tumor necrosis factor exposure (HR, 6.5; 95% CI, 1.3-33.8; P = .03) predicted clinical relapse after thiopurine withdrawal. CONCLUSIONS: Thiopurine withdrawal did not affect vedolizumab trough concentrations. However, it may increase fecal calprotectin, histologic, and histo-endoscopic activity. Histologic activity and prior anti-tumor necrosis factor exposure may predict disease relapse on thiopurine withdrawal for patients using vedolizumab for UC.

ABSTRACT
BACKGROUND AND AIMS: Ustekinumab (UST) is an effective biologic for treatment of inflammatory bowel disease (IBD). However, some patients treated with UST have suboptimal clinical response with standard dosing. The aims of this study were to determine the effectiveness of UST dose intensification (DI), identify factors associated with DI, cumulative incidence of DI and persistence of UST among treated patients. METHODS: Clinical data of patients with Crohn's disease (CD) and ulcerative colitis (UC) who received UST from September 2017 to October 2022 in Singapore General Hospital were collected. Primary outcome was defined as achieving corticosteroid-free clinical remission, biochemical remission, endoscopic healing and/or transmural healing (CD). Statistical analysis was performed to identify factors, which are predictive of UST DI and effectiveness of UST DI. RESULTS: Forty-two patients (34 CD and 8 UC) underwent UST DI to either 6-weekly (n = 19, 45.2%) or 4-weekly (n = 23, 35.9%) and the median time to intensification was 31.1 weeks (17.8-65.7). Presence of perianal disease in CD (HR 4.9; 1.47-16.4) was associated with DI. After DI, 16 (38%) patients achieved primary outcome by week 52. The overall drug persistence rates at 1 year and 2 years were 75.7% (95% CI 62.9-84.6) and 63.5% (95% CI 49.9-74.3), respectively. CONCLUSION: Two third of IBD patients underwent DI while on UST treatment and the median time to DI was about 6 months after induction. CD patients with perianal disease is more likely to undergo DI. More than one third of dose-intensified patients achieved remission by week 52.

OBJECTIVES: Prevalence of malnutrition among ambulatory inflammatory bowel disease (IBD) patients in Singapore is unknown. We aimed to evaluate the prevalence of ambulatory IBD patients at risk of malnutrition (ARMN) using Malnutrition Universal Screening Tool (MUST) and its clinical outcomes. METHODS: IBD patients were recruited from March to June 2018 and followed up for 6 months. ARMN patients were defined as having a MUST score of 2 or more compared with those not at risk (non-ARMN). RESULTS: Altogether 217 patients were recruited, including 128 (59.0%) with ulcerative colitis (UC) and 89 (41.0%) with Crohn's disease (CD). The mean body mass index (BMI) was 23.5 ± 4.5 kg/m2 ; 35 (16.1%) patients were on biologics, and 52 (24.0%) were on steroids. Among them 25 (11.5%) patients were ARMN, with a predominance of UC (n = 15, 60.0%). The majority of ARMN patients were underweight (n = 23, 92.0%) while 114 (59.4%) non-ARMN patients were overweight. ARMN patients had a significantly lower albumin (38.3 g/L vs 41.9 g/L) and a significantly increased proportion of patients with C-reactive protein ≥5 mg/L (36.0% vs 19.3%). There was a trend towards longer hospital stay among ARMN patients, although this was not statistically significant. Use of biologics or immunomodulators and albumin levels were associated with being ARMN. CONCLUSION: Using MUST, 11.5% of our ambulatory IBD patients in Singapore were identified to be ARMN. Among ARMN patients, a trend was demonstrated towards a longer hospital stays for admitted patients. This underscores the need to actively screen ambulatory IBD patients for malnutrition.

BACKGROUND AND AIMS: Motorized spiral enteroscopy (MSE) has been postulated to ease the complexities of the standard-of-care double-balloon enteroscopy (DBE). However, there are no comparative studies between MSE and DBE. This study aimed to compare the therapeutic outcomes and safety between MSE and DBE. METHODS: In this case-matched study, patients were matched 1:2 (MSE/DBE) by age, sex, body mass index, and American Society of Anesthesiology scores. Thirty-one patients who underwent MSE were compared with 62 patients who underwent DBE from 2014 to 2022. Our primary outcomes were to compare the technical and diagnostic success rates between DBE and MSE. Our secondary outcomes were to compare the therapeutic success and adverse event rates. RESULTS: The main indications for enteroscopy were suspected GI bleeding and positive radiologic findings. Prior abdominal surgery was reported in 35.5% and 22.6% of DBE and MSE patients, respectively. Most were antegrade enteroscopy (71%). We found no significant difference in the technical success (DBE 98.4% vs MSE 96.8%, P = .62), diagnostic success (DBE 66.1% vs MSE 54.8%, P = .25), and therapeutic success rates (DBE 62.8% vs MSE 52.9%, P = .62) between the groups. Adverse events occurred in 1 DBE and 11 MSE patients. Most were minor (n = 10, 25.6%). Two patients (5.1%) in the MSE group sustained deep lacerations in the proximal esophagus requiring hospitalization. One developed ileal perforation after MSE needing surgical repair. CONCLUSIONS: In patients requiring enteroscopy, the diagnostic and therapeutic performance of MSE is similar to DBE. An increased frequency of adverse events was observed with MSE. There are some restrictions in the indication because of the design of MSE.

Background and Aim: Thiopurines are recommended for maintenance of steroid-free remission (SFR) in inflammatory bowel disease (IBD). Thiopurine metabolite monitoring (MM) is increasingly used in the West but remains novel in Singapore, with limited information on its therapeutic and economic benefits. Hence, this study aims to investigate MM's clinical utility and its impact on healthcare resource utilization in Singaporean IBD patients. Methods: A retrospective observational study was conducted at Singapore General Hospital outpatient IBD Centre. Patients with IBD, baseline MM during 2014-2017, and weight-based thiopurine doses for ≥4 weeks were followed up for 1 year. Actions were taken to optimize therapy, and metabolite levels before and after the first action were documented. Outcomes assessed included SFR, no therapy escalation or surgery, healthcare resource utilization, and direct healthcare costs. Results: Ninety IBD patients (50 Crohn's disease, 40 ulcerative colitis) were included. Among them, 40% had baseline metabolite levels within therapeutic range, 31.1% sub-therapeutic, 21.1% supra-therapeutic, and 7.8% shunters. Repeated MM with subsequent dose optimization helped 67.2% of patients achieve therapeutic levels after 1 year. Overall, 87.8% of patients achieved SFR and 90% had no therapy escalation or surgery. Despite greater outpatient visits and laboratory investigations with MM, the median total healthcare costs at 1 year only increased marginally (S$6407.66 [shunters] vs S$5215.20 [supra-therapeutic] vs S$4970.80 [sub-therapeutic] vs S$4370.48 [control (within therapeutic range)], P = 0.592). Conclusion: MM guided timely therapy escalation for non-responders, identification of non-adherence, and reversal of shunting. Therefore, it is a useful clinical tool to optimize thiopurines without significantly increasing healthcare costs.
ABSTRACT
Background and Aim: Patients with inflammatory bowel disease (IBD) requiring infliximab frequently spend hours to attend treatment. Through quality improvement (QI) methodology, we aimed to shorten the time spent in the biologics infusion center using the accelerated infusion protocol and describe patient outcomes, safety, and associated cost savings. Methods: From September 2018 through December 2019, eligible IBD patients receiving infliximab were recruited. We implemented interventions including the accelerated infusion protocol, and modifying collection location of infliximab. Statistical process control charts were created. Patients' clinical outcome and cost savings data were analyzed using descriptive statistics and Pearson's chi-square. Results: During the study period, a total of 60 patients with IBD receiving infliximab were recruited. A total of 315 infusions were administered-152 were under accelerated infusion protocol and 163 under standard protocol. The mean infliximab infusion time was reduced by 47%, from 2.4 h (142 ± 14 min) to 1.2 h (75 ± 10 min) (142 min vs 75 min, P < 0.001), with total time spent in the infusion center reduced by 52%, from 3.6 h (214 ± 25 min) to 1.7 h (102 ± 14 min) (214 vs 106 min, P < 0.001). Three mild infusion-related reactions (3/152 = 1.97%) were recorded. Estimated cost savings over the 16-month project period was SGD $6721.4 (nursing) and SGD $23 560 (patients). A high level of satisfaction (4.84 out of 5) with the protocol was reported. Conclusion: Our QI project shortened the infliximab infusion time and total time spent in the infusion center, without compromising patient safety. Estimated cost savings were substantial. The protocol helps reduce work productivity loss.
ABSTRACT
BACKGROUNDPatients undergoing immune-modifying therapies demonstrate a reduced humoral response after COVID-19 vaccination, but we lack a proper evaluation of the effect of such therapies on vaccine-induced T cell responses.METHODSWe longitudinally characterized humoral and spike-specific T cell responses in patients with inflammatory bowel disease (IBD), who were on antimetabolite therapy (azathioprine or methotrexate), TNF inhibitors, and/or other biologic treatment (anti-integrin or anti-p40) for up to 6 months after completing 2-dose COVID-19 mRNA vaccination.RESULTSWe demonstrate that a spike-specific T cell response was not only induced in treated patients with IBD at levels similar to those of healthy individuals, but also sustained at higher magnitude for up to 6 months after vaccination, particularly in those treated with TNF inhibitor therapy. Furthermore, the spike-specific T cell response in these patients was mainly preserved against mutations present in SARS-CoV-2 B.1.1.529 (Omicron) and characterized by a Th1/IL-10 cytokine profile.CONCLUSIONDespite the humoral response defects, patients under immune-modifying therapies demonstrated a favorable profile of vaccine-induced T cell responses that might still provide a layer of COVID-19 protection.FUNDINGThis study was funded by the National Centre for Infectious Diseases (NCID) Catalyst Grant (FY2021ES) and the National Research Fund Competitive Research Programme (NRF-CRP25-2020-0003).

BACKGROUND AND AIMS: Small bowel adenocarcinoma (SBA) is a rare neoplasm that is associated with Crohn's disease (CD). This study aims to quantify the prevalence of CD-SBA, review the current evidence of histopathology and molecular analysis findings, and identify the clinical presentation and outcomes of CD-SBA. METHODS: Electronic databases Medline and Embase were searched for articles describing SBA in inflammatory bowel disease patients. The histopathology, molecular analysis findings, clinical presentation, prevalence, and outcomes of CD-SBA were extracted, and results were pooled with random effects. RESULTS: In total, 33 articles were included in the analysis. Prevalence of SBA was 1.15 (CI: 0.31-2.33) per 1000 CD patients. Only 11% (CI: 0.04-0.21) of CD-SBA patients had observable radiological features. CD-SBA was most commonly found in the ileum (84%), diagnosed at stage 2 (36%), with main presenting complaints including obstruction, weight loss, and abdominal pain. Significant histopathological findings included adjacent epithelial dysplasia, and an equal distribution of well-differentiated (49%) and poorly differentiated subtypes (46%). Most prevalent genetic mutation was KRAS mutation (18%), followed by mismatch repair deficiency (9.7%). The 5-year overall survival for CD-SBA patients was 29% (CI: 0.18-0.41), and 33% (CI: 0.26-0.41) for de novo SBA. No statistically significant increase in risk for CD-SBA was noted for treatment with thiopurines, steroids, and 5-ASA. CONCLUSION: Our meta-analysis found the prevalence of CD-SBA to be 1.15 per 1000 CD patients. The 5-year overall survival for CD-SBA was poor. The presenting symptoms were non-specific, and therefore the diagnosis requires a high index of suspicion.

Psoriatic arthritis (PsA) is a chronic inflammatory disease that presents with psoriasis (PsO), peripheral and axial arthropathy. The heterogeneity of disease presentation leads to the term "psoriatic disease (PsD)" which is thought to better encompass the range of clinical manifestations. PsA is associated with several comorbidities such as cardiovascular diseases, metabolic syndrome and other extra-articular manifestations including uveitis, and inflammatory bowel disease (IBD). While novel therapeutics are being developed following advances in our understanding of the pathogenesis of the disease, the diverse combinations of PsA with its various comorbidities still pose a clinical challenge in managing patients with PsA. This article reviews our current understanding of the pathogenesis of PsA and how various pathways in the pathogenesis lead to the two comorbid extra-articular manifestations - uveitis and IBD. We also review current evidence of treatment strategies in managing patients with PsA with comorbidities of uveitis and/or IBD.
ABSTRACT
AIMS: Upper gastrointestinal Crohn's disease (UGI-CD) is an important subclassification of Crohn's Disease (CD). We performed a systematic review and meta-analysis to evaluate the prevalence, risk factors, and clinical outcomes associated with UGI-CD. METHODS: We searched Embase and Medline for articles reporting the clinical information of UGI-CD in CD patients, through 27 October 2020. Disease location and phenotype were coded according to the Montreal classification, and results were pooled with random effects by DerSimonian and Laird model. RESULTS: 26 articles were included. The prevalence of UGI-CD was 13%. UGI-CD was most commonly found in the stomach (56%) and was associated with concurrent ileocolonic involvement (54%). Non-stricturing, non-penetrating UGI-CD was the most common behavioral phenotype (61%). L4-jejunal disease was associated with the highest rates of surgery. Region of origin did not significantly influence the location and phenotype of UGI-CD. Young, male patients presenting with erythema nodosum, aphthous ulcers and stricturing-phenotype are more likely to have UGI-CD, which in turn is linked to increased risk of hospitalization and surgery. CONCLUSION: UGI-CD is present in 13% of patients with CD, and patients with L4-jejunal disease are more likely to require surgery. Further studies examining the effect of ethnicity and region on UGI-CD are needed.

OBJECTIVE: There is debate on the best method of colorectal cancer (CRC) surveillance in inflammatory bowel disease (IBD). We aimed to examine how gastroenterologists around the world practice CRC surveillance and manage dysplastic lesions in IBD. METHODS: A 22-question survey was emailed to gastroenterologists from 34 countries. It included questions on resources for, frequency and mode of CRC surveillance, and management of colorectal dysplasia. Fisher's exact test and logistic regression were used to evaluate the differences among respondents in various domains. RESULTS: There were 217 eligible responses, with most gastroenterologists working in public hospitals (76%), and treating >10 patients with IBD weekly (71%). High-definition white light endoscopy (HDWLE) was available in 93.1% of the centers. The preferred mode of surveillance was HDWLE with dye-spray chromoendoscopy and targeted biopsies (41.2%). Fewer than 50% of physicians reported using chromoendoscopy in >50% of cases, citing time as the limiting factor (73.7%). Of these gastroenterologists 63% infrequently (<25% of cases) performed random biopsies during chromoendoscopy. They would attempt endoscopic mucosal resection for polypoid lesions >10 mm (67.2%), including >20 mm lesions with low grade dysplasia (49.8%), and non-polypoid lesions >10 mm without dysplasia (56.9%). For non-polypoid lesions >20 mm with low- and high-grade dysplasia, referral to expert endoscopists was the preferred option. CONCLUSION: The preferred method of CRC surveillance was HDWLE with chromoendoscopy and targeted biopsies. Random biopsies were infrequently performed. The uptake of chromoendoscopy for surveillance in practice was low. Physicians varied in their approach in removing endoscopically resectable dysplastic lesions.

INTRODUCTION: Patients with inflammatory bowel disease(IBD) are at risk of infections, many of which are preventable with vaccinations. We performed a systematic review on various aspects of vaccination in IBD. METHODS: We searched PubMed, and EMBASE databases, through 31 January 2021. Primary outcomes included vaccination rates, predictors of vaccination, reasons of vaccination hesitancy and acceptance, and outcomes of intervention. Findings were presented with medians, ranges, and narrative synthesis. RESULTS: We included 33 observational studies comprising 146,918 patients and 681 physicians. The median vaccination rates of influenza, pneumococcal pneumonia, and hepatitis B vaccines were 42%(IQR, 28%-61.5%), 20%(IQR, 9%-38.5%), and 48%(IQR, 29%-53%), respectively. Uses of immunosuppressant, older age and physician recommendations have positive influence on vaccination rate. Lack of vaccine-related knowledge and awareness of need for vaccination are main reasons of vaccine hesitancy among patients and physicians. There was disagreement between gastroenterologists and primary-care physicians on whose responsibility to offer vaccination. Education was the sole intervention identified, with variable success. CONCLUSION: This systematic review demonstrates that the vaccination rates of IBD patients, similar to other chronic diseases, are suboptimal. Lack of vaccine-related knowledge and awareness of the need for vaccination are main reasons of vaccine hesitancy amongst patients and physicians. Education, though effective, was the only available intervention identified. Gastroenterologist could take the lead in educating, and initiating vaccination among IBD patients.

OBJECTIVE: Preventing the postoperative recurrence (POR) of Crohn's disease (CD) poses a significant challenge to clinicians. With the advent of biologics, various studies have observed a reduction of recurrence after surgery. Hence, we performed a systematic review and meta-analysis to identify the rate of POR at different time points in the era of biologic use. METHODS: We performed a literature search using Medline and Embase databases for studies investigating biologics in preventing the POR of CD. Data were extracted, and a single-arm meta-analysis with generalized linear mixed model and Clopper-Pearson method for confidence interval (CI) was performed to identify endoscopic, clinical and surgical recurrence rates at 6 months and 1, 2 and 5 years postoperatively. RESULTS: Altogether 24 studies were included in the meta-analysis. The endoscopic, clinical and surgical POR rate with the use of anti-tumor necrosis factor (TNF)-α agents at 1 year was 21.72% (95% CI 16.28%-28.37%), 13.06% (95% CI 8.18%-18.92%) and 3.76% (95% CI 1.37%-9.91%), respectively. The 5-year recurrence rate was 84.21% (95% CI 72.35%-91.57%) and 17.49% (95% CI 9.17%-30.80%) for endoscopic and surgical recurrence, respectively. Subgroup analyses at 1 year for the type of anti-TNF-α agent or the timing of initiation after surgery showed no significant difference in endoscopic, clinical and surgical recurrence rates. CONCLUSIONS: Anti-TNF-α agents are effective at preventing clinical, endoscopic and surgical POR of CD. The timing of initiating biological therapy after surgery has no significant effect on the rate of POR. The efficacy of infliximab and adalimumab for postoperative recurrence prevention is similar.

OBJECTIVES: To determine the age-standardised prevalence of inflammatory bowel disease (IBD) in a metropolitan area of Sydney, with a focus on its prevalence among older people. DESIGN, SETTING: Population-based epidemiological study of people with IBD in the City of Canada Bay, a local government area in the inner west of Sydney, during 1 March 2016 - 10 November 2016. PARTICIPANTS: Patients diagnosed with confirmed IBD according to the Copenhagen or revised Porto criteria. MAIN OUTCOME MEASURES: Crude prevalence of IBD, including Crohn disease and ulcerative colitis; age-standardised prevalence of IBD, based on the World Health Organization standard population; prevalence rates among people aged 65 years or more. RESULTS: The median age of 364 people with IBD was 47 years (IQR, 34-62 years); 185 were women (50.8%). The crude IBD prevalence rate was 414 cases (95% CI, 371-456 cases) per 100 000 population; the age-standardised rate was 348 cases (95% CI, 312-385 cases) per 100 000 population. The age-standardised rate for Crohn disease was 166 cases (95% CI, 141-192 cases) per 100 000 population; for ulcerative colitis, 148 cases (95% CI, 124-171 cases) per 100 000 population. The IBD prevalence rate in people aged 65 years or more was 612 cases (95% CI, 564-660 cases) per 100 000, and for those aged 85 years or more, 891 cases (95% CI, 833-949 cases) per 100 000; for people under 65, the rate was 380 cases (95% CI, 342-418 cases) per 100 000. CONCLUSIONS: We found that the prevalence of confirmed IBD in a metropolitan sample was highest among older people. Challenges for managing older patients with IBD include higher rates of comorbid conditions, polypharmacy, and cognitive decline, and the immunosuppressive nature of standard therapies for IBD.

BACKGROUND AND AIM: Patients with functional dyspepsia (FD) often have concomitant anxiety and depression. Mindfulness-based cognitive therapy (MBCT) combines the principles of cognitive behavioral therapy and mindfulness. It is a group-based therapy and has been shown to be efficacious in functional gastrointestinal disorders. There are no randomized controlled trials (RCTs) evaluating MBCT in FD. We aimed to evaluate feasibility and efficacy of MBCT in FD management. METHODS: We performed a mixed-method single-center pilot randomized trial of 28 patients fulfilling ROME-III criteria for FD. Fifteen patients were randomized to an 8-week MBCT program while 13 underwent treatment-as-usual (TAU). Patients completed questionnaires at baseline and at week 8. Two focus-groups were conducted. Feasibility of recruitment, acceptability of randomization, procedures and intervention, handout compliance and feasibility of quantitative measures were assessed. The primary outcome was subjective-clinical-assessment of FD symptoms (SCA-FD). Secondary outcome measures included Short-form Nepean Dyspepsia Index (SF-NDI), subjective-clinical-assessment of general health (SCA-GH), EuroQoL-Visual Analog Scale (EuroQoL-VAS), and Depression, Anxiety and Stress Scale-21 Items (DASS-21). RESULTS: Twelve of 15 patients in the MBCT group completed the program. There was a trend towards symptom improvement, with 90% in the MBCT group reporting improvement in SCA-FD compared with 45% in TAU(P = 0.063). Patients who underwent MBCT reported greater improvement in SF-NDI (mean change: -8.8 (SD: 7.5) vs -0.7 (7.2), P = 0.018) and DASS-21 (-19.8 (29.5) vs -5.5 (6.6) P = 0.13) compared with TAU. There was no difference in SCA-GH and EuroQoL-VAS. Based on SCA-FD improvement, the eventual RCT will require 50 patients (25 in each group). CONCLUSIONS: Mindfulness-based cognitive therapy is likely efficacious for FD, and it would be feasible to conduct a RCT.

BACKGROUND: Incidence of inflammatory bowel disease (IBD) is increasing in newly industrialised countries (NICs); however, data on suboptimal response to anti-tumor necrosis factor (anti-TNF) agents are limited. OBJECTIVES: To assess incidence and indicators of suboptimal response to first anti-TNF therapy in IBD patients in NICs. METHODS: A chart review was conducted in ten countries from Asia-Pacific (APAC), Latin America (LatAm), and Russia and the Middle East (RME) regions among patients diagnosed with ulcerative colitis (UC) or Crohn's disease (CD), initiating anti-TNF therapy in 2010-2015. The cumulative incidence of suboptimal response to anti-TNF therapy was assessed using the following indicators: dose escalation or discontinuation, augmentation with non-biologic therapy, IBD-related hospitalization, or surgery. RESULTS: The study included 1,674 patients (570 UC; 1,104 CD). At 24 months, 32.9% of UC (APAC: 45.1%; LatAm: 38.2%; RME: 23.8%) and 41.2% of CD patients (APAC: 54.1%; LatAm: 42.5%; RME: 29.5%) had experienced suboptimal response. The most frequent first indicator was non-biologic therapy augmentation in LatAm (41.7%), IBD-related hospitalization in RME (UC: 50.7%; CD:37.3%) and in APAC for CD (39.1%), and anti-TNF discontinuation in APAC for UC (38.3%). CONCLUSION: Suboptimal response to anti-TNF agents is common in IBD patients in NICs. Observed regional differences in the incidence and indicators may reflect local practice and anti-TNF restrictions in IBD management. NCT REGISTRATION NUMBER: NCT03090139.

BACKGROUND AND AIMS: Comorbidities, polypharmacy, malignancies, and infections complicate management of elderly patients with inflammatory bowel diseases (IBD). This study assessed gastroenterologists' preference in the prescription of medications or surgery to elderly patients with IBD, and the factors associated with their choices. METHODS: An international case-based survey was conducted that presented three cases of steroid-dependent ulcerative colitis assessing young-age versus elderly-age patients, with and without comorbidity. Physician characteristics and practice demographics were collected. Factors associated with selection of different choices of therapy were determined by logistic regression analysis. RESULTS: A total of 424 respondents from 41 countries were included. Vedolizumab (53.2%) and thiopurines (19.4%) were the top treatment preferences for moderate-to-severe ulcerative colitis (P < 0.0001). Comorbidity and older age were independently associated with more frequent use of vedolizumab (P < 0.0001), and less frequent use of immunomodulators and anti-tumour necrosis factor (TNF; P < 0.0001). Comorbidity was the only independent predictor for selecting colectomy (P < 0.0001). A history of lymphoma (94%) and opportunistic infection (78.3%) were the most frequent conditions precluding the use of thiopurine and anti-TNF in elderly patients with IBD. Only 6.1% of respondents considered patient age a limit for vedolizumab, while 37.9% considered age as a limiting factor in prescribing thiopurines (P < 0.001). Geographical heterogeneity was identified with significantly more physicians from Oceania and North America favouring the use of vedolizumab. CONCLUSION: Vedolizumab was the preferred first-line agent in the treatment of elderly patients with IBD with steroid-dependent moderate-to-severe ulcerative colitis. Older age and presence of comorbidity influenced the selection of medication. Comorbidity was the main predictor of colectomy. Geographical heterogeneity in prescribing habits may relate to medication reimbursement in individual countries.
