RESUMO
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.

BACKGROUND & AIMS: Rapid symptomatic relief is an important treatment goal for patients with ulcerative colitis (UC). We aimed to characterize early response with ustekinumab in patients with moderate-to-severe UC during the initial 16 weeks of treatment. METHODS: We performed a post hoc analysis of data from A Study to Evaluate the Safety and Efficacy of Ustekinumab Induction and Maintenance Therapy in Participants With Moderately to Severely Active Ulcerative Colitis trial. Patients (N = 961) were randomized (1:1:1) to receive intravenous 130 mg ustekinumab, approximately 6 mg/kg ustekinumab, or placebo at week 0. Symptomatic remission, absolute stool number, Mayo stool frequency and rectal bleeding subscores, partial Mayo score, C-reactive protein, and fecal calprotectin were assessed in the overall population and for patients in the biologic-naïve or prior biologic failure subgroups. RESULTS: A significantly greater percentage of patients in the 130-mg ustekinumab (20.0%; P = .015) or approximately 6-mg/kg ustekinumab (20.2%; P = .012) groups achieved symptomatic remission at week 2 vs placebo (12.9%). Mean [SD] changes from baseline in daily stool number on day 7 were greater in the ustekinumab groups (-1.1 [2.6] in 130 mg [P = .065] and -1.2 [2.5] in â¼6 mg/kg [P = .017]) vs placebo (-0.7 [2.7]). The percentage of patients with Mayo stool frequency subscore of 1 or less and rectal bleeding subscore of 0 increased from baseline through week 16 for both ustekinumab groups. Significant improvements in partial Mayo scores were observed by week 2 in both ustekinumab groups vs placebo (P ≤ .001). Significantly more patients in the ustekinumab groups had normalized C-reactive protein levels from week 2 to week 8 vs placebo (P ≤ .05). Similar results were observed with normalized fecal calprotectin levels between week 2 and week 4 (P ≤ .05). CONCLUSIONS: Ustekinumab improved symptoms in patients with UC compared with placebo in as early as 7 days, indicating rapid onset of effect after induction. CLINICAL TRIAL REGISTRY NUMBER: ClinicalTrials.gov: NCT02407236.

INTRODUCTION: Endoscopic healing is currently considered the main target in the management of ulcerative colitis (UC). There are conflicting data about the role of histology as a stricter treatment objective. We aim at evaluating the additional benefit of histologic remission over endoscopic remission. METHODS: We performed a prospective observational study at the McGill University Health Center. We enrolled adult patients with UC in clinical remission for at least 3 months undergoing a colonoscopy. Endoscopic disease activity was based on the Mayo endoscopic score. Rectal biopsies were obtained, and the histologic activity was evaluated using the Geboes score (active disease defined as Geboes score ≥ 3.1) with the addition of assessing the presence of basal plasmacytosis. Patients were followed up for 12 months for disease relapse defined as a partial Mayo score of > 2. At the time of relapse or end of follow-up, all patients underwent repeat endoscopic evaluation. The primary end point was clinical relapse. RESULTS: Two hundred fifty-three patients were included. The presence of basal plasmacytosis was associated with relapse (adjusted odd ratio = 2.07, 95% confidence interval [CI] 1.06-4.18, P = 0.042). Time to clinical relapse was significantly higher for patients with Mayo endoscopic score > 0 with adjusted hazard ratio = 2.65, 95% CI 1.31-5.39, and P = 0.007. Time to clinical relapse was not significantly higher for Geboes score ≥ 3.1 with adjusted hazard ratio = 1.29, 95% CI 0.67-2.49, and P = 0.45. DISCUSSION: Active histologic disease did not affect time to clinical relapse in patients with UC who achieved endoscopic remission while the presence of basal plasmacytosis is associated with relapse.

BACKGROUND: Fucosyltransferase 2 (FUT2) participates in intestinal antigen secretion and bacterial adherence. FUT2 homozygous nonsense mutations (FUT2M) and subsequent nonsecretor status is associated with Crohn's disease (CD). The common null allele is rs601338. We assessed the relationship between FUT2M and disease course. METHODS: In consecutive adult CD outpatients, clinical, biochemical, and genetic data were collected at baseline visits. Patients were longitudinally followed over 5 years. The primary outcome analyzed the relationship between FUT2M and rates of CD patients in persistent steroid-free clinical remission requiring neither surgery, biologics, nor immunomodulators. RESULTS: Sixty-two CD patients were recruited. FUT2M homozygotes (rs601338 or any mutation in linkage disequilibrium) were detected in 27% of CD (17/62). Patients with rs601338 mutations had higher rates of the primary outcome (homozygous: 46.6%, heterozygous: 28.0%, wild-type: 5.3%, P=0.02). Similar findings existed for CD patients with homozygous mutations in any single-nucleotide polymorphism for FUT2 (homozygous: 41.2%, heterozygous: 25.9%, wild-type: 5.6%, P=0.04). On multivariable analysis, rs601338 mutation was associated with the primary outcome (odds ratio=3.4, 95% confidence interval: 1.3-8.7, P=0.01), while other parameters were not. Mutation of rs601338 was associated with lower rates of penetrating disease (homozygous: 13.3%, heterozygous: 28.0%, wild-type: 52.6%, P=0.05) and particularly in high-risk patients (homozygous: 0%, heterozygous: 37.5%, wild-type: 83.3%, P=0.01). CONCLUSIONS: FUT2 mutation status is associated with a favorable clinical course in CD. Further confirmatory studies are needed.

BACKGROUND: In this systematic review, our objective was to assess inflammatory bowel disease (IBD) patient preferences and perspectives relating to their disease diagnosis, treatment, knowledge needs and telemedicine. METHODS: This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Four databases and conference proceedings were searched between January 1, 1980, and May 1, 2020. The methodological quality of the included studies was assessed using the Standards for reporting qualitative research checklist. RESULTS: Our search identified 240 citations and 52 studies met the inclusion criteria. The major expectations of the patients are symptomatic and pain control, quality of life and normal endoscopy. Patients' main concerns are access to information and healthcare, and shared decision making. At the time of diagnosis, patients expressed a greater need for knowledge about their IBD, preferentially by their treating gastroenterologist. The main treatment expectations in active disease are efficacy, safety and convenience. Patients are willing to accept relatively high risks of complications from medical therapy to avoid a permanent ostomy and to achieve durable remission. Patients are more interested in disease monitoring, research and development during the time of remission. Telemedicine and self-management with supervised e-health tools are feasible and acceptable amongst patients with IBD. CONCLUSION: This systematic review demonstrates that patients with IBD expect more information about their disease process, shared decision making and symptom control. Further research is needed to help align patient and physician expectations in order to improve the quality of care provided to patients with IBD.

BACKGROUND AND AIMS: The value of ustekinumab (UST) therapeutic drug monitoring (TDM) in clinical practice remains unclear. This study examined the impact of UST TDM on clinical decision making in patients with Crohn's disease (CD). METHODS: A total of 110 consecutive UST-treated CD patients were enrolled in this multicenter, single-arm cross-sectional study. During a single study visit, clinical decisions, disease characteristics, and serum and fecal samples were obtained. The primary outcome was congruency of the actual and two hypothetical clinical decisions based on provision of UST TDM (with and without fecal calprotectin [FCP]) to participating clinicians. Decisions were compared against those of a review panel. A sub-study retrospectively measured the associations of clinical outcomes at the next follow-up visit with serum UST concentration [UST]. RESULTS: No differences in the pattern of decisions by clinicians were observed before and after provision of UST TDM (P = 1.0) or UST TDM + FCP (P = 0.86). However, 39% (TDM) and 50% (TDM + FCP) of hypothetical decisions differed from the initial decisions. The review panel's decisions differed with the addition of TDM + FCP (P = 0.0006), but not TDM alone (P = 0.16). The sub-study (n = 53) failed to detect an association between therapeutic serum [UST] at the initial study visit and clinical outcomes at the next visit. CONCLUSIONS: In consecutive CD patients treated with UST, the addition of TDM into routine clinical practice did not significantly impact clinical decisions and there was no association between short-term clinical outcomes and serum [UST]. Further studies are warranted before clinicians routinely implement UST TDM into clinical practice.

BACKGROUND: Optimal management of patients with ulcerative colitis (UC) requires the accurate, objective assessment of disease activity. AIMS: We aimed to determine how strong patient-reported outcomes, clinical scores and symptoms correlate with endoscopy and biomarkers for assessment of disease activity in patients with UC. METHODS: Consecutive patients with UC followed at the McGill University IBD Center and referred for endoscopy (surveillance or flare) were included prospectively between September 2018 and August 2020. Patient-reported outcome (PRO2), partial Mayo, Simple Clinical Colitis Activity Index (SCCAI), Mayo endoscopic subscore (MES) and Baron and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) scores were calculated. C-reactive protein (CRP) and fecal calprotectin (FCAL) were collected. RESULTS: A total of 171 patients with UC [age: 49(IQR:38-61) years, female: 46.2%, 57.3% extensive disease, 42.7% on biologicals] were included prospectively. Rectal bleeding (RBS), stool frequency (SF) subscore of 0, or total PRO2 remission (RBS0 and SF ≤ 1), partial Mayo (≤ 2) and SCCAI (≤ 2.5) remission were similarly associated with mucosal healing defined by MES (0 or ≤ 1), Baron (0 or ≤ 1) or UCEIS (≤ 3) scores in ROC analysis (AUC:0.93-0.72). There was a moderate-to-strong agreement between MES Baron and UCEIS (K = 0.91-0.41). A UCEIS of ≤ 3 was identified as the best cutoff to clinical or endoscopic remission. Agreement between CRP and clinical remission or endoscopic healing (MES/Baron) was poor (K ~ 0.2), while agreement between FCAL and RBS-PRO2 or MES/Baron/UCEIS was moderate to strong (K = 0.44-0.70). CONCLUSIONS: Agreement between RBS, SF, PRO2, partial Mayo and SCCAI in predicting endoscopic healing was moderate to strong, while no clinically meaningful difference was found in accuracy across the scores and definitions. FCAL, but not CRP, was associated to clinical and endoscopic remission.

BACKGROUND: Treatment options for acute severe ulcerative colitis (ASUC) are limited. Tofacitinib, an approved treatment for moderate to severe ulcerative colitis, could be a potential rescue therapy for ASUC given its rapid onset of action. OBJECTIVE: To evaluate the effectiveness of tofacitinib in hospitalized patients with ASUC refractory to standard therapy in a real-world setting. METHODS: Retrospective observational study of hospitalized adult patients with ASUC treated with tofacitinib between January 2019 and September 2020 at five Canadian centers. We extracted patient demographics, clinical status, biomarkers (C-reactive protein and fecal calprotectin), endoscopic findings, and colectomy-free rate at admission, 30 days, 90 days, and 6 months after tofacitinib initiation. RESULTS: Eight patients with symptoms refractory to standard rescue therapy (corticosteroids ± infliximab if infliximab-naïve prior to admission) were treated with tofacitinib. During index hospitalization, clinical response was observed in 5/8 patients. The median time to discharge post-tofacitinib initiation was 5 days (IQR 5.0-6). At 30 and 90 days, all five responders were in clinical remission. At 6 months, only 3/5 responders remained in clinical remission. The colectomy-free rate was 37.5% during the follow-up period (two colectomies occurred within 30 days; one occurred within 90 days). No drug-related adverse reaction occurred. CONCLUSION: In this small case-series, tofacitinib was an effective rescue therapy in patients with refractory ASUC. These findings need to be evaluated in a randomized controlled trial.

BACKGROUND & AIMS: Noninvasive tests to measure endoscopic activity in patients with Crohn's disease (CD) have limitations. We aimed to develop a test to identify patients in remission, based on endoscopic analysis, and monitor CD activity based on serum levels of proteins. METHODS: We developed a test to measure 13 proteins in blood (ANG1, ANG2, CRP, SAA1, IL7, EMMPRIN, MMP1, MMP2, MMP3, MMP9, TGFA, CEACAM1, and VCAM1), called the endoscopic healing index [EHI], using samples from 278 patients with CD from a multinational training cohort. We validated the test using 2 independent cohorts of patients with CD: 116 biologic-naive patients with early-stage CD (validation cohort 1) and 195 biologic-exposed patients with chronic CD (validation cohort 2). The ability of the test to identify patients with active disease vs patients in remission (defined as a simple endoscopic score for CD of ≤2 and ≤1 in each segment, or a total CD endoscopic index of severity score <3) was assessed by using area under receiver operating characteristic curve (AUROC) analysis. The diagnostic accuracy of the test was compared with that of measurement of serum C-reactive protein (CRP) and fecal calprotectin. RESULTS: The EHI scores range from 0 to 100 units; higher scores indicate more severe CD activity, based on endoscopy findings. The EHI identified patients in remission with an AUROC of 0.962 in validation cohort 1 (95% confidence interval, 0.942-0.982) and an AUROC of 0.693 in validation cohort 2 (95% confidence interval, 0.619-0.767), regardless of CD location or phenotype. A cutoff value of 20 points identified patients in remission with the highest level of sensitivity (97.1% in validation cohort 1 and 83.2% in validation cohort 2), with specificity values of 69.0% and 36.6%, respectively. A cutoff value of 50 points identified patients in remission with the highest level of specificity (100% in validation cohort 1 and 87.8% in validation cohort 2), with sensitivity values of 37.3% and 30.0%, respectively. The EHI identified patients in remission with a significantly higher AUROC value than the test for CRP (0.876, P < .001 in validation cohort 1 and 0.624, P = .109 in validation cohort 2). In analysis of patients with available FC measurements, the AUROC value for the EHI did not differ significantly from that of measurement of FC (AUROC, 0.950 for EHI vs AUROC, 0.923 for FC; P = .147 in validation cohort 1 and AUROC, 0.803 for EHI vs AUROC, 0.854 for FC; P = .298 in validation cohort 2). CONCLUSIONS: We developed an index called the EHI to identify patients with CD in endoscopic remission based on blood levels of 13 proteins. The EHI identified patients with resolution of endoscopic disease activity, with good overall accuracy, although with variation between the 2 cohorts assessed. The EHI AUROC values were comparable to measurement of FC and higher than measurement of serum CRP. The test might be used in practice to assess endoscopic activity in patients with CD.

In the context of the Severe Acute Respiratory Syndrome Coronavirus 2 pandemic, we have developed a novel negative pressure aerosol protector for upper endoscopy (TRACEY). TRACEY is the first endoscopic enclosure to have passed stringent testing for aerosol protection. The following describes its clinical use in a single-center prospective case series. Overall, 15 patients were included. All endoscopic procedures were successful without premature removal of TRACEY. In addition, its use did not lead to significant patient discomfort, technical hinderance, or adverse events. TRACEY seems to offer a safe and easy to use aerosol protection for upper endoscopy and a potential Severe Acute Respiratory Syndrome Coronavirus 2 mitigation strategy in endoscopy.

Therapeutic drug monitoring (TDM) of biologics is a rapidly evolving field. We aimed to provide a consensus statement regarding the clinical utility of TDM for biologics in inflammatory bowel disease (IBD). A modified Delphi method was applied to develop consensus statements. A comprehensive literature review was performed regarding TDM of biologic therapies in IBD, and 45 statements were subsequently formulated on the potential application of TDM in IBD. The statements, along with literature, were then presented to a panel of 10 gastroenterologists with expertise in IBD and TDM who anonymously rated them on a scale of 1-10 (1 = strongly disagree and 10 = strongly agree). An expert consensus development meeting was held virtually to review, discuss, refine, and reformulate statements that did not meet criteria for agreement or that were ambiguous. During the meeting, additional statements were proposed. Panelists then confidentially revoted, and statements rated ≥7 by 80% or more of the participants were accepted. During the virtual meeting, 8 statements were reworded, 7 new statements were proposed, and 19 statements were rerated. Consensus was finally reached in 48/49 statements. The panel agreed that reactive TDM should be used for all biologics for both primary nonresponse and secondary loss of response. It was recommended that treatment discontinuation should not be considered for infliximab or adalimumab until a drug concentration of at least 10-15 µg/mL was achieved. Consensus was also achieved regarding the utility of proactive TDM for anti-tumor necrosis factor therapy. It was recommended to perform proactive TDM after induction and at least once during maintenance. Consensus was achieved in most cases regarding the utility of TDM of biologics in IBD, specifically for reactive and proactive TDM of anti-tumor necrosis factors.

BACKGROUND: Immunomodulator monotherapy is an important component in the treatment of inflammatory bowel disease (IBD). However, there is conflicting literature about thiopurines maintaining long-term remission in patients with active IBD. AIM: To determine the durable clinical remission rate in adults with Crohn's disease (CD) or ulcerative colitis (UC) on thiopurine monotherapy over 5 years. METHODS: We performed a retrospective analysis of adult patients identified at McGill University Health Centre from 2009 to 2012. We included IBD patients who initiated thiopurine monotherapy and were in remission for at least 3 months (Harvey-Bradshaw Index (HBI) < 5 points for CD and partial Mayo Score (pMS) < 2 points in UC). The primary endpoint was sustained clinical remission on thiopurines during a 5-year follow-up. This included patients who had not relapsed or discontinued the drug due to side effects. The secondary endpoint was clinical relapse over the follow-up period, which was defined as HBI > 5 in CD and pMS > 2 in UC. RESULTS: There were 148 patients included in the study (100 CD; 48 UC). At 5 years, 23% (34/148) patients remained in clinical remission on thiopurine monotherapy (25 CD and 9 UC patients). Thirty-three percent (33/100) of CD and 46% (22/48) of UC patients relapsed while on thiopurines. There was no difference in relapse rates between CD and UC patients. Eighty-four percent (42/50) of patients with CD with side effects and all UC (17/17) patients who experienced side effects discontinued the drug. CONCLUSION: This analysis demonstrates that there is poor sustainability of clinical remission in IBD patients on thiopurine monotherapy given that a high proportion of patients discontinue thiopurines due to either relapse or side effects.

BACKGROUND: Evaluating clinical data on the safety and efficacy of vedolizumab (VDZ) in 'real-world' setting is still desirable. Recent reports have raised concerns that arthralgia may be associated with VDZ. AIMS: The aim of this study is to present clinical experience with VDZ from a tertiary IBD center. METHODS: Retrospective chart reviews were performed of consecutive patients exposed to VDZ between 2015 and 2018. Clinical, biomarker, and endoscopic efficacy and safety data were evaluated. RESULTS: A total of 130 IBD (75CD, 55UC) patients were included. Median duration of VDZ therapy was 65 weeks. Probability of drug discontinuation was 4.9% and 9.4% at 1 and 2 years. Dose intensification was more frequent in CD compared to UC (at 1 and 2 years: 64.8/87.9% vs. 26.5/35.7%, p < 0.001). Clinical remission rates at 3-, 6- and 12 months were 44.4%, 71.4% and 77.1% in UC, and 9.1%, 26.7% and 29.2% in CD patients, respectively. Prior use of multiple biologic agents was associated with diminished efficacy of VDZ in CD. Three new cases of arthralgia were encountered during follow-up. CONCLUSION: Vedolizumab (VDZ) therapy displayed good drug sustainability and clinical efficacy in a population with severe disease phenotype and high rates of previous anti-TNF failure. Frequent dose intensification was required. The safety profile was good, and no association between newly onset arthralgia and VDZ therapy was observed.

BACKGROUND & AIMS: Optimal management of patients with ulcerative colitis (UC) requires assessment of disease activity-usually by endoscopy, which is invasive, costly, and not risk free. We performed a systematic review to determine whether clinical symptoms correlate with findings from endoscopy assessments of patients with UC. METHODS: We performed a systematic review of publication databases from January 1980 through July 2018 to identify clinical trials and observational studies reporting correlations among symptoms, disease activity index scores and/or patient reported outcomes (rectal bleeding and/or stool frequency), and endoscopic disease activity. Correlations were ascertained in patients with active vs inactive disease and by disease extent and treatment type. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Because of significant heterogeneity, meta-analysis was not possible. Results were synthesized qualitatively and systematically. RESULTS: Our final analysis included 23 studies (1 randomized trial, 22 observational studies) comprising 3320 patients with UC. The studies used a variety of measures to assess clinical activity, endoscopic activity, and measures of correlation (sensitivity, specificity, correlation coefficients, area under the receiver operator curve). Overall, studies were at moderate-high risk of bias. Composite clinical measures, including rectal bleeding and stool frequency, had moderate to strong correlations with endoscopic disease activity; the absence of rectal bleeding identified patients with inactive disease with higher levels of sensitivity than normalization of stool frequency. In general, symptoms correlated more strongly with endoscopic activity in patients with left-sided colitis than extensive colitis. The effect of different medications on the correlation between clinical and endoscopic activity has not been well studied. CONCLUSIONS: In a systematic review, we found a moderate to strong correlation between clinical activity, particularly the combination of rectal bleeding and stool frequency, and endoscopic activity in patients with UC. Although these clinical assessments could help prioritize patients for endoscopic evaluation in resource-limited settings, challenges associated with treating patients based on symptoms alone preclude adaptation of current management algorithms.

BACKGROUND & AIMS: Crohn's disease (CD) is a lifelong illness with substantial morbidity, although new therapies and treatment paradigms have been developed. We provide guidance for treatment of ambulatory patients with mild to severe active luminal CD. METHODS: We performed a systematic review to identify published studies of the management of CD. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an iterative online platform and then finalized and voted on by a group of specialists. RESULTS: The consensus includes 41 statements focused on 6 main drug classes: antibiotics, 5-aminosalicylate, corticosteroids, immunosuppressants, biologic therapies, and other therapies. The group suggested against the use of antibiotics or 5-aminosalicylate as induction or maintenance therapies. Corticosteroid therapies (including budesonide) can be used as induction, but not maintenance therapies. Among immunosuppressants, thiopurines should not be used for induction, but can be used for maintenance therapy for selected low-risk patients. Parenteral methotrexate was proposed for induction and maintenance therapy in patients with corticosteroid-dependent CD. Biologic agents, including tumor necrosis factor antagonists, vedolizumab, and ustekinumab, were recommended for patients failed by conventional induction therapies and as maintenance therapy. The consensus group was unable to clearly define the role of concomitant immunosuppressant therapies in initiation of treatment with a biologic agent. CONCLUSIONS: Optimal management of CD requires careful patient assessment, acknowledgement of patient preferences, evidence-based use of existing therapies, and thorough assessment to define treatment success.

BACKGROUND AND OBJECTIVES: Rare but potentially life-threatening hypersensitivity reactions can occur during the administration of intravenous iron. To provide guidance to healthcare professionals caring for adults receiving intravenous iron, a panel of 10 Canadian clinical experts developed a practical algorithm for the identification and management of hypersensitivity reactions to intravenous iron. MATERIALS AND METHODS: A systematic search of PubMed to February 2018 was performed. Articles related to hypersensitivity reactions were selected for review. The algorithm was developed during a 1-day live meeting based on the literature review and clinical expertise where evidence was lacking. The algorithm was then refined through an iterative process involving a web-based platform and virtual meetings. RESULTS: The algorithm provides guidance to healthcare professionals in preparing for and administering IV iron, as well as recognizing and managing hypersensitivity reactions to intravenous iron. Considerations for re-challenging patients who have experienced prior reactions are provided. CONCLUSION: Healthcare professionals who are involved in the care of patients receiving intravenous iron should be trained to anticipate, recognize and manage hypersensitivity reactions to intravenous iron to optimize patient care.

BACKGROUND AND OBJECTIVE: Optimization strategies with infliximab (IFX) are increasingly used as rescue therapy for steroid refractory acute severe ulcerative colitis (ASUC). We aim to determine if intensified IFX induction improves colectomy rate and identifies outcome predictors. METHODS: Hospitalized adult patients who received IFX for ASUC between 2010 and 2016 were identified. We compared standard inductions (5 mg/kg) vs high-dose induction (10 mg/kg) with 3-month colectomy rate as primary outcome. RESULTS: Seventy-two patients (62.5% male, median age 38.5) were identified. Thirty-seven patients (51.3%) received 5 mg/kg IFX and 35 received 10 mg/kg. Baseline clinical, biochemical and endoscopic parameters were well matched between these two groups. 10 mg/kg was more likely to be used by clinicians from 2014 onwards (p < 0.001). Three-month colectomy rate was 9.7%; which was not significantly different between the standard (5.4%) and high-dose (14.3%) IFX induction (p = 0.205). CRP ≥ 60 (OR 10.9 [95% CI 1.23-96.50], p = 0.032), hemoglobin ≤ 90 g/L (OR 15.6 [95% CI 2.61-92.66], p = 0.036) and albumin < 30 g/L (OR 9.4 [95% CI 1.06-83.13], p = 0.044) were associated with increased risk of colectomy at 3 months in univariate regression analysis. CONCLUSION: Use of high-dose infliximab rescue therapy did not improve 3-month colectomy-free survival in this cohort. Tailored use in high-risk patients may be beneficial although further validation is required.

BACKGROUND: Reactivation of LTBI in patients with IBD on anti-TNF-α agents can lead to serious life-threatening illness. No gold standard exists for the detection of LTBI. We examined whether a dual testing strategy with TST and IGRA would improve the detection of LTBI. METHODS: Consecutive IBD patients being considered for anti-TNF-α treatment underwent testing with a TST, IGRA and CXR. All patients completed a self-administered questionnaire. The association of both tests with demographic factors, LTBI risk factors, BCG vaccination, IS therapy and agreement between the TST and IGRA were evaluated. RESULTS: One-hundred and fifty-five IBD patients were included, 6% were TST positive and 5% were IGRA positive. Concordance between TST and IGRA was fair (κ = 0.21, 95% CI - 0.081-0.498). Neither test was affected by age, gender or BCG vaccination. The presence of risk factors for LTBI was found to be positively associated with TST (OR 19.8, 95% CI 3.9-102.1), but not IGRA. IGRA was negatively associated with IS therapy (OR 0.06, 95% CI 0.007-0.5), but not TST. Four patients who were IGRA positive but TST negative were treated for LTBI by a respirologist. CONCLUSION: An IGRA result was negatively associated with IS therapy, while the presence of risk factors for LTBI was found to be positively associated with TST results. There was fair agreement between positive TST and IGRA results. The addition of IGRA to the standard practice of TST and CXR increased the number of cases that were initiated on LTBI therapy.

BACKGROUND: Direct head-to-head studies comparing the long-term outcomes of infliximab (IFX) to adalimumab (ADA) in Crohn's disease (CD) are sparse. AIMS: We compared the short-term and long-term efficacy and safety of IFX and ADA in CD. METHODS: We performed a single-center retrospective study including biologic-naïve adult patients with CD who were started on IFX or ADA at the McGill University Health Center. The primary end points were clinical response and remission at 12 months. Secondary end points included corticosteroid-free remission at 12 months, durable remission, and treatment failure with need for steroids, hospitalization or surgery. Safety was also assessed. RESULTS: Two hundred and twenty patients were included (143 IFX, 77 ADA). Patients on IFX had a higher prevalence of fistulizing or perianal disease and corticosteroid treatment at baseline. Rates of clinical remission and corticosteroid-free remission at 12 months were similar between both groups: 63.8 versus 76.3% (p = 0.139) and 54.1 versus 44.7% (p = 0.354), respectively, for IFX and ADA. Combination therapy led to significantly higher remission rates at 12 months compared to monotherapy for patients on IFX (81.2 vs. 52.1%, p = 0.008), but not for those on ADA. Higher rates of adverse events were reported with IFX compared to ADA (p = 0.006). CONCLUSIONS: Our real-life experience in biologic-naïve CD patients demonstrated that patients started on IFX were more likely to have a harder-to-treat phenotype. Despite that, efficacy end points were similar between both groups. Clinical remission was higher in patients with combination therapy for IFX, but not for those on ADA. This warrants further investigation.
