  • Onset of Ulcerative Colitis in a Patient with Nonalcoholic Fatty Liver
           Disease (NAFLD): Dramatic Effect of Plant-based Diet for NAFLD
    • Authors: Chiba M; Nakane K, Abe H, et al.
      Abstract: AbstractNonalcoholic fatty liver disease (NAFLD) develops in ulcerative colitis (UC) and Crohn’s disease. However, there is scarce reporting on the onset of UC in patients with NAFLD.A 44-year-old man was diagnosed with UC and referred to us in 2019. His height was 166.0 cm, and body weight was 86.3 kg. The waist circumference was 93.7 cm (normal range <85) and triglyceride was 751 mg/dL. These findings, in addition to hypertension, resulted in a diagnosis of metabolic syndrome. HbA1c was normal. Ultrasonography disclosed severe fatty liver. Nonalcoholic fatty liver disease was diagnosed. He underwent 12 days of educational hospitalization for UC. A lacto-ovo-semi-vegetarian diet (1400 kcal/day), a kind of plant-based diet (PBD), was provided. He lost 4 kg, which was 4.6% of his base body weight. Triglyceride and total cholesterol decreased to the normal ranges. Transaminases and γ-glutamyl transpeptidase also decreased. His body weight decreased further after discharge. Follow-up ultrasonography indicated an improvement in hepatic enlargement. The shear wave velocity decreased from 1.11 to 0.88 m/s. His soft stool became normal stool by 2 months after discharge.Records of his health checkups revealed the presence of metabolic syndrome and abnormal liver function tests already in 2015. Thus, it was concluded that UC developed in a patient with NAFLD in this case. Plant-based diet has already been shown to be effective in inflammatory bowel disease (IBD). In the present case, NAFLD parameters were dramatically improved by PBD. Whether the improvement was due to weight loss per se or due to weight loss with PBD is to be clarified.

      Abstract: This prospective observational study including consecutive patients with inflammatory bowel disease treated with either infliximab or adalimumab showed that although the correlation between the ELISA and the homogeneous mobility shift assay was good for both drugs, the agreement was poor.

           Disease Collaborative: Design, Implementation, and Validation of a
           Disease-specific Module
    • Authors: Eisenstein S; Holubar S, Hilbert N, et al.
      Pages: 1731 - 1739
      Abstract: AbstractBackgroundSurgery for inflammatory bowel disease (IBD) involves a complex interplay between disease, surgery, and medications, exposing patients to increased risk of postoperative complications. Surgical best practices have been largely based on single-institution results and meta-analyses, with multicenter clinical data lacking. The American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) has revolutionized the way in which large-volume surgical outcomes data have been collected. Our aim was to employ the ACS-NSQIP to collect disease-specific variables relevant to surgical outcomes in IBD.Study DesignA collaborative of 13 high-volume IBD surgery centers was convened to collect 5 IBD-specific variables in NSQIP. Variables included biologic and immunomodulator medications usage, ileostomy utilization, ileal pouch anastomotic technique, and colonic dysplasia/neoplasia. A sample of the Surgical Clinical Reviewer collected data was validated by a colorectal surgeon at each institution, and kappa's agreement statistics generated.ResultsOver 1 year, data were collected on a total of 956 cases. Overall, 41.4% of patients had taken a biologic agent in the 60 days before surgery. The 2 most commonly performed procedures were laparoscopic ileocolic resections (159 cases) and subtotal colectomies (151 cases). Overall, 56.8% of cases employed an ileostomy, and 134 ileal pouches were constructed, of which 92.4% used stapled technique. A sample of 214 (22.4%) consecutive cases was validated from 8 institutions. All 5 novel variables were shown to be reliably collected, with excellent agreement for 4 variables (kappa ≥ 0.70) and very good agreement for the presence of colonic dysplasia (kappa = 0.68).ConclusionWe report the results of the initial year of implementation of the first disease-specific collaborative within NSQIP. The selected variables were demonstrated to be reliably collected, and this collaborative will facilitate high-quality, large case–volume research specific to the IBD patient population.

  • Decellularized Human Gut as a Natural 3D Platform for Research in
           Intestinal Fibrosis
    • Authors: Giuffrida P; Curti M, Al-Akkad W, et al.
      Pages: 1740 - 1750
      Abstract: AbstractBackgroundThe current methodologies for the identification of therapeutic targets for inflammatory bowel disease (IBD) are limited to conventional 2-dimensional (2D) cell cultures and animal models. The use of 3D decellularized human intestinal scaffolds obtained from surgically resected intestine and engineered with human intestinal cells may provide a major advancement in the development of innovative intestinal disease models. The aim of the present study was to design and validate a decellularization protocol for the production of acellular 3D extracellular matrix (ECM) scaffolds from the human duodenum.MethodsScaffolds were characterized by verifying the preservation of the ECM protein composition and 3D architecture of the native intestine and were employed for tissue engineering with primary human intestinal myofibroblasts for up to 14 days.ResultsEngrafted cells showed the ability to grow and remodel the surrounding ECM. mRNA expression of key genes involved in ECM turnover was significantly different when comparing primary human intestinal myofibroblasts cultured in 3D scaffolds with those cultured in standard 2D cultures on plastic dishes. Moreover, incubation with key profibrogenic growth factors such as TGFβ1 and PDGF-BB resulted in markedly different effects in standard 2D vs 3D cultures, further emphasizing the importance of using 3D cell cultures.ConclusionsThese results confirm the feasibility of 3D culture of human intestinal myofibroblasts in intestinal ECM scaffolds as an innovative platform for disease modeling, biomarker discovery, and drug testing in intestinal fibrosis.

  • Systematic Review and Meta-analysis: Short-Chain Fatty Acid
           Characterization in Patients With Inflammatory Bowel Disease
    • Authors: Zhuang X; Li T, Li M, et al.
      Pages: 1751 - 1763
      Abstract: AbstractBackgroundAlterations in gut microbiota and short-chain fatty acids (SCFAs) have been reported in inflammatory bowel disease (IBD), but the results are conflicting. The aim of this study was to perform a meta-analysis to explore the characterization of SCFAs in IBD patients and their potential role in the occurrence and development of IBD.MethodsCase–control studies investigating SCFAs in IBD patients were identified from several English databases. The standardized mean difference (SMD) with 95% confidence interval (CI) was calculated using the random-effects model.ResultsThe SMDs of acetate, valerate, and total SCFAs in ulcerative colitis (UC) patients were –0.51 (95% CI, –0.90 to –0.13), –0.65 (95% CI, –1.02 to –0.28), and –0.51 (95% CI, –0.95 to –0.07), respectively. The SMDs of acetate, propionate, and butyrate in patients with active UC were –1.74 (95% CI, –3.15 to –0.33), –2.42 (95% CI, –4.24 to –0.60), and –1.99 (95% CI, –3.39 to –0.60), respectively. However, the SMD of butyrate in UC patients in remission was 0.72 (95% CI, 0.34 to 1.11). In addition, the SMDs of acetate, butyrate, and valerate in Crohn’s disease (CD) patients were –1.43 (95% CI, –2.81 to –0.04), –0.77 (95% CI, –1.39 to –0.14), and –0.75 (95% CI, –1.47 to –0.02), respectively. Finally, the SMDs of acetate, propionate, butyrate, valerate, and lactate in IBD patients were –2.19 (95% CI, –3.98 to –0.39), –1.64 (95% CI, –3.02 to –0.25), –1.98 (95% CI, –3.93 to –0.03), –0.55 (95% CI, –0.93 to –0.18), and 4.02 (95% CI, 1.44 to 6.61), respectively.ConclusionsThere were alterations of SCFAs in IBD patients, and inconsistent SCFA alterations were found in CD and UC. More importantly, inverse SCFA alterations existed in patients with active UC and those in remission.

  • Systematic Review With Meta-analysis: Epidemiology of Nonalcoholic Fatty
           Liver Disease in Patients With Inflammatory Bowel Disease
    • Authors: Zou Z; Shen B, Fan J.
      Pages: 1764 - 1772
      Abstract: AbstractBackgroundNonalcoholic fatty liver disease (NAFLD) is increasingly identified in patients with inflammatory bowel disease (IBD), but there are few systematic reviews and meta-analyses of the studies of NAFLD in IBD patients.MethodsMEDLINE, Web of Science, Cochrane Library, and Scopus were searched (until August 2018) to identify observational studies that reported the prevalence and risk factors for NAFLD in IBD patients. Pooled prevalence, odds ratios (OR), mean difference (MD), and 95% confidence intervals (95% CI) were calculated. Study quality was assessed using the modified Newcastle-Ottawa scale.ResultsOf the 662 citations evaluated, 19 studies (including 5620 subjects) reported the prevalence of NAFLD in IBD population and were included for the analysis. The overall pooled prevalence was 27.5% (95% CI, 20.7%–34.2%). The prevalence was higher in older patients (MD = 8.22; 95% CI, 6.22–10.22), type 2 diabetes (OR = 3.85; 95% CI, 2.49–5.95), hypertension (OR = 3.18; 95% CI, 2.36–4.28), obesity (OR = 2.79; 95% CI, 1.73–4.50), insulin resistance (OR = 6.66; 95% CI, 1.28–34.77), metabolic syndrome (OR = 4.96; 95% CI, 3.05–8.05), chronic kidney disease (OR = 4.83; 95% CI, 1.79–13.04), methotrexate use (OR = 1.76; 95% CI, 1.02–3.06), surgery for IBD (OR = 1.28; 95% CI, 1.02–1.62), and longer duration of IBD (MD = 5.60; 95% CI, 2.24–8.97).ConclusionsWe found that NAFLD was not uncommon in the IBD population. Older age, metabolic risk factors, methotrexate use, prior surgery, and longer duration of IBD are predictors for the presence of NAFLD in IBD. Screening of NAFLD might be recommended among IBD patients with the aforementioned factors.

  • Prevalence of Fistulizing Crohn’s Disease in the United States: Estimate
           From a Systematic Literature Review Attempt and Population-Based Database
    • Authors: Schwartz D; Tagarro I, Carmen Díez M, et al.
      Pages: 1773 - 1779
      Abstract: BackgroundFistulas may arise as a relevant complication of Crohn’s disease (CD). Despite their clinical significance and the substantial burden imposed on patients, limited data are available on the epidemiology of fistulizing CD in the United States.MethodsA systematic literature review was conducted to identify data published between 1970 and 2017 on the epidemiology of fistulas in patients with CD, with the aim to estimate the number of prevalent cases in the United States. Retrieved titles and abstracts were screened by 2 independent researchers for inclusion criteria (US population-based studies reporting data on the epidemiology of fistulizing CD). To validate the literature-based estimate, data from a US claims database (Truven Health MarketScan database) were analyzed. This database has broad geographic coverage, with health care data for >60 million patients during the period of the analysis.ResultsThe literature search retrieved 7 articles for full-text review, and only 1 met the criteria for inclusion. This study described the cumulative incidence of fistulas in a CD population from Minnesota over 20 years. From the reported data, the estimated number of prevalent cases with fistulizing CD in the United States was ~76,600 in 2017 (~52,900 anal, ~7400 rectovaginal, ~2300 enterocutaneous, and ~14,100 internal). Analysis from the US health care database resulted in an estimated number of ~75,700 patients, confirming the robustness of the original estimate from the literature.ConclusionsBased on 2 separate analyses, the estimated number of patients with fistulizing CD in the United States is ~77,000 patients.

  • Lipidomics in Ulcerative Colitis Reveal Alteration in Mucosal Lipid
           Composition Associated With the Disease State
    • Authors: Diab J; Hansen T, Goll R, et al.
      Pages: 1780 - 1787
      Abstract: ABSTRACTBackgroundThe onset of ulcerative colitis (UC) is associated with alterations in lipid metabolism and a disruption of the balance between pro- and anti-inflammatory molecules. Only a few studies describe the mucosal lipid biosignatures during active UC. Moreover, the dynamics of lipid metabolism in the remission state is poorly defined. Therefore, this study aims to characterize mucosal lipid profiles in treatment-naïve UC patients and deep remission UC patients compared with healthy subjects.MethodsTreatment-naïve UC patients (n = 21), UC patients in deep remission (n = 12), and healthy volunteers (n = 14) were recruited. The state of deep remission was defined by histological and immunological remission defined by a normalized TNF-α gene expression. Mucosa biopsies were collected by colonoscopy. Lipid analysis was performed by means of ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS-MS). In total, 220 lipids from 11 lipid classes were identified.ResultsThe relative concentration of 122 and 36 lipids was altered in UC treatment-naïve patients and UC remission patients, respectively, compared with healthy controls. The highest number of significant variations was in the phosphatidylcholine (PC), ceramide (Cer), and sphingomyelin (SM) composition. Multivariate analysis revealed discrimination among the study groups based on the lipid profile. Furthermore, changes in phosphatidylethanolamine(38:3), Cer(d18:1/24:0), and Cer(d18:1/24:2) were most distinctive between the groups.ConclusionThis study revealed a discriminant mucosal lipid composition pattern between treatment-naïve UC patients, deep remission UC patients, and healthy controls. We report several distinctive lipids, which might be involved in the inflammatory response in UC, and could reflect the disease state.

  • CARMIL2 Deficiency Presenting as Very Early Onset Inflammatory Bowel
    • Authors: Magg T; Shcherbina A, Arslan D, et al.
      Pages: 1788 - 1795
      Abstract: AbstractBackgroundChildren with very early onset inflammatory bowel diseases (VEO-IBD) often have a refractory and severe disease course. A significant number of described VEO-IBD-causing monogenic disorders can be attributed to defects in immune-related genes. The diagnosis of the underlying primary immunodeficiency (PID) often has critical implications for the treatment of patients with IBD-like phenotypes.MethodsTo identify the molecular etiology in 5 patients from 3 unrelated kindred with IBD-like symptoms, we conducted whole exome sequencing. Immune workup confirmed an underlying PID.ResultsWhole exome sequencing revealed 3 novel CARMIL2 loss-of-function mutations in our patients. Immunophenotyping of peripheral blood mononuclear cells showed reduction of regulatory and effector memory T cells and impaired B cell class switching. The T cell proliferation and activation assays confirmed defective responses to CD28 costimulation, consistent with CARMIL2 deficiency.ConclusionOur study highlights that human CARMIL2 deficiency can manifest with IBD-like symptoms. This example illustrates that early diagnosis of underlying PID is crucial for the treatment and prognosis of children with VEO-IBD.

  • Analysis of Genetic Association of Intestinal Permeability in Healthy
           First-degree Relatives of Patients with Crohn’s Disease
    • Authors: Turpin W; Espin-Garcia O, Bedrani L, et al.
      Pages: 1796 - 1804
      Abstract: AbstractExcessive intestinal permeability or intestinal barrier dysfunction as measured by various assays has been observed in various diseases. However, little is known about the factors contributing to altered gut permeability in these diseases. Our objective was to determine the genetic determinants of altered gut permeability as measured by the lactulose mannitol fractional excretion ratio (LacMan ratio) in 1075 healthy first-degree relatives of patients with Crohn’s disease (CD). In a targeted analysis of single nucleotide polymorphisms (SNPs) located in genes associated with intestinal barrier function related or not to inflammatory bowel disease, we did not find a significant association with intestinal permeability. In an untargeted genome-wide association analysis, the top 100 associations were located in 22 genomic loci, although they were not statistically significant after correction for multiple testing (raw P values [1.8 × 10–7 - 1.4 × 10–5]. The lowest P value was obtained for rs9616637 (22q13.33, C22orf34), for which the minor allele A was associated with a decreased LacMan ratio. These results suggest that host genetic background has limited contribution toward intestinal permeability. Despite this, our study is currently the largest of its kind assessing gut permeability in vivo. It remains possible that smaller genetic effect sizes on LacMan ratio are not detectable in this sized cohort. Larger studies are warranted to identify the potential genetic contribution to intestinal permeability.

  • Comparative Efficacy of Vedolizumab and Adalimumab in Ulcerative Colitis
           Patients Previously Treated With Infliximab
    • Authors: Favale A; Onali S, Caprioli F, et al.
      Pages: 1805 - 1812
      Abstract: AbstractBackgroundAdalimumab (ADA) and vedolizumab (VDZ) have shown efficacy in moderate to severe ulcerative colitis (UC) patients who failed infliximab (IFX). Although, a comparative efficacy evaluation of ADA and VDZ in this clinical setting is currently missing.AimThe aim of this study is to compare the efficacy of ADA and VDZ in patients affected by UC who failed IFX.MethodsClinical records of UC patients from 8 Italian IBD referral centers who failed IFX and were candidates to receive either ADA or VDZ were retrospectively reviewed. The primary end point was therapeutic failure at week 52. Secondary end points included therapy discontinuation at weeks 8, 24 and 52, the discontinuation-free survival, and safety.ResultsOne hundred sixty-one UC patients, 15 (9.2%) primary, 83 (51.6%) secondary IFX failures, and 63 (39.2%) IFX intolerants were included. Sixty-four (40%) patients received ADA and 97 (60%) VDZ as second line therapy. At week 52, 37.5% and 28.9% of patients on ADA and VDZ, respectively, had therapeutic failure (P = 0.302). However, the failure rate was significantly higher in the ADA group as compared with VDZ group among IFX secondary failures (48.0% ADA vs 22.4%VDZ, P = 0.035). The therapy discontinuation-free survival was significantly higher in the group of IFX secondary failures who received VDZ as compared with ADA at both the univariate (P = 0.007) and multivariate survival analysis (OR 2.79; 95% CI, 1.23–6.34; P = 0.014). No difference in the failure and biologic discontinuation-free survival was observed in the IFX primary failure and intolerant subgroups.ConclusionVedolizumab might be the therapy of choice in those UC patients who showed secondary failure to IFX.

  • Association of Infliximab Levels With Mucosal Healing Is Time-Dependent in
           Crohn’s Disease: Higher Drug Exposure Is Required Postinduction Than
           During Maintenance Treatment
    • Authors: Feng T; Chen B, Ungar B, et al.
      Pages: 1813 - 1821
      Abstract: AbstractBackgroundInfliximab levels have been reported to be associated with mucosal healing (MH) in Crohn’s disease (CD). However, whether the association differs between postinduction (week 14) and maintenance (week 30) has seldom been investigated. We aimed to analyze the association between serum infliximab trough levels and MH at the 2 different time points.MethodsA retrospective study of CD patients treated with infliximab in a tertiary referral center between January 2012 and May 2018 was conducted. MH was defined as absence of ulceration by endoscopy. Correlations between infliximab level and MH were investigated at 2 specific time points, weeks 14 and 30.ResultsMedian infliximab levels were higher in patients with MH than those without at weeks 14 (7.5 vs 1.5 μg/mL; P < 0.001) and 30 (5.9 vs 0.5 μg/mL; P < 0.001). The median levels in patients with MH at week 14 were higher than at week 30 (7.5 vs 5.9 μg/mL; P < 0.05). Multivariate analysis showed that infliximab level was independently associated with MH (both P < 0.001 at weeks 14 and 30). Infliximab level above 4.85 μg/mL and 2.85 μg/mL identified patients with MH at week 14 (area under the curve [AUC], 0.796; P < 0.001) and week 30 (AUC, 0.780; P < 0.001) with 80% specificity. The rates of MH reached a plateau (>85%) when infliximab levels were above 10 and 6 μg/mL at weeks 14 and 30, respectively.ConclusionsInfliximab levels correlated with MH at weeks 14 and 30 in CD patients. Higher levels might be required to achieve MH at postinduction than during maintenance treatment.

  • Improving the Quality of Inpatient Ulcerative Colitis Management:
           Promoting Evidence-Based Practice and Reducing Care Variation With an
           Inpatient Protocol
    • Authors: Lewin S; McConnell R, Patel R, et al.
      Pages: 1822 - 1827
      Abstract: AbstarctBackgroundHospitalization for ulcerative colitis is a high-risk period associated with increased risk of Clostridium difficile infection, thromboembolism, and opiate use. The study aim was to develop and implement a quality-improvement intervention for inpatient ulcerative colitis management that standardizes gastroenterology consultant recommendations and improves delivery of evidence-based care.MethodsAll adult patients hospitalized for ulcerative colitis between July 1, 2014, and December 31, 2017, who received intravenous corticosteroids were included. On July 1, 2016, the UCSF Inpatient Ulcerative Colitis Protocol was implemented, featuring standardized core recommendations and a daily checklist for gastroenterology consultant notes, a bundled IBD electronic order set, and an opiate awareness campaign. The composite primary outcome was adherence to all 3 evidence-based care metrics: C. difficile testing performed, pharmacologic venous thromboembolism (VTE) prophylaxis ordered, and opiates avoided.ResultsNinety-three ulcerative colitis hospitalizations occurred, including 36 preintervention and 57 postintervention. Age, gender, disease duration, disease extent, and medication use were similar preintervention and postintervention. C. difficile testing was performed in 100% of hospitalizations. Venous thromboembolism prophylaxis was ordered on 84% of hospital days before intervention compared with 100% after intervention (P ≤ 0.001). Opiates were administered in 67% of preintervention hospitalizations, compared with 53% of postintervention hospitalizations (P = 0.18). The median daily dose of oral morphine equivalents decreased from 12.1 mg before intervention to 0.5 mg after intervention (P = 0.02). The composite outcome of adherence to all 3 metrics was higher after intervention (25% vs. 47%, P = 0.03).ConclusionsEvidence-based inpatient ulcerative colitis management may be optimized with standardized algorithms that reinforce core principles, reduce care variation, and do not require IBD specialists to implement.

           After Biologic Initiation in Inflammatory Bowel Disease
    • Authors: Limketkai B; Singh S, Jairath V, et al.
      Pages: 1828 - 1837
      Abstract: AbstractBackgroundWe assessed practice patterns for monitoring mucosal inflammation after biologic initiation and the association between monitoring approaches and development of disease-related complications for Crohn’s disease (CD) and ulcerative colitis (UC).MethodsThis study used a Truven Health MarketScan (2007–2016) query for CD and UC patients initiating biologic therapy. Cumulative 24-month disease-related complications (corticosteroids, change of biologic, hospitalization, surgery) in patients undergoing proactive disease monitoring with lower endoscopy, fecal calprotectin, or cross-sectional radiographic enterography (computed tomography enterography or magnetic resonance enterography) within 6 months of biologic initiation vs no early monitoring after biologic initiation were compared. Cox proportional hazard ratios (HRs with 95% confidence intervals [CIs]) adjusted for propensity score were used.ResultsWithin the first 24 months after biologic initiation, monitoring (proactive or reactive) was performed in 56.4% of CD patients and 67.8% of UC patients, with considerable geographic variability. Early (within 6 months) proactive monitoring was endoscopy-based (87.9%), performed in 11% of CD (n = 2195/19,899) and 12.8% of UC (n = 925/7247) patients. Compared with no early monitoring, early proactive monitoring was associated with a reduction in disease-related complications for CD (adjusted HR [aHR], 0.90; 95% CI, 0.84–0.96) and UC (aHR, 0.87; 95% CI, 0.78–0.97) and predominately driven by a reduction in corticosteroid use (CD: aHR, 0.83; 95% CI, 0.77–0.90; UC: aHR, 0.77; 95% CI, 0.69–0.87). Results were consistent across multiple sensitivity analyses.ConclusionsEarly proactive monitoring of mucosal inflammation in CD and UC within 6 months of biologic initiation was associated with reduction in disease-related complications over 24 months, primarily related to reduced steroid utilization. Wide variation exists in practice patterns for monitoring of mucosal inflammation after biologic initiation.

  • Impact of Changing Treatment Strategies on Outcomes in Pediatric
           Ulcerative Colitis
    • Authors: Bolia R; Rajanayagam J, Hardikar W, et al.
      Pages: 1838 - 1844
      Abstract: AbstractBackgroundIn recent years, treatment strategies for ulcerative colitis have evolved with an early step-up approach, the availability of biologicals, and therapeutic drug monitoring.We carried out this study to evaluate the effect of these changes on disease outcomes.MethodsIn this retrospective review, 2 time periods were defined: Group 1 (2005–2010) and Group 2 (2011–2016). Baseline demographic, endoscopic parameters, and medication use were compared. Overall colectomy rate, number of disease flares per year, and number of hospital admissions per year were compared between the 2 groups.ResultsGroup 1 had 71 children, and in children in Group 2. The use of 5-ASA increased in Group 2 (Group 2, 99.2% vs. Group 1, 84.5%, P = 0.0007). In addition, infliximab and thiopurines were introduced earlier in the disease course.The 2-year cumulative probability of colectomy decreased from 14% to 3% (P = 0.02) between the 2 periods. No change in median number of flares per year [Group 1, 0.41 (IQR 0.6) vs. Group 2, 0.62 (IQR 0.91), P = 0.28] or median number of hospital admissions per year [Group 1, 0.30 (IQR 0.77) vs. Group 2, 0.21 (IQR 0.75), P = 0.52] was seen.Thereafter, we proceeded to identify the changes in treatment strategies that were responsible for the reduction in colectomy and we found that the use of infliximab OR 3.7 (95% CI 1.1–11.7), P = 0.02, was independently associated with it.ConclusionsA reduction in 2-year colectomy rates has been observed in patients with pediatric ulcerative colitis since biologics have become available for its treatment. The numbers of disease-flares rates and hospital admissions remain unchanged.

  • Development of an Objective Model to Define Near-Term Risk of Ileocecal
           Resection in Patients with Terminal Ileal Crohn Disease
    • Authors: Grass F; Fletcher J, Alsughayer A, et al.
      Pages: 1845 - 1853
      Abstract: AbstractBackgroundThe decision to either escalate medical therapy or proceed to ileocecal resection (ICR) in patients with terminal ileal Crohn disease (CD) remains largely subjective. We sought to develop a risk score for predicting ICR at 1 year from computed tomography or magnetic resonance enterography (CTE/MRE).MethodsWe conducted a retrospective cohort study including all consecutive adult (> 18 years) patients with imaging findings of terminal ileal CD (Montreal classification: B1, inflammatory predominant; B2, stricturing; or B3, penetrating) on CTE/MRE between January 1, 2016, and December 31, 2016. The risk for ICR at 6 months and at 1 year of CTE/MRE and risk factors associated with ICR, including demographics, CD-specific immunosuppressive therapeutics, and disease presentation at the time of imaging, were determined.ResultsOf 559 patients, 121 (21.6%) underwent ICR during follow-up (1.4 years [IQR 0.21–1.64 years]); the risk for ICR at 6 months and at 1 year was 18.2% (95% CI 14.7%–21.6%) and 20.5% (95% CI 16.8%–24.1%), respectively. Multivariable analysis revealed Montreal classification (B2, hazard ratio [HR] 2.73, and B3, HR 6.80, both P < 0.0001), upstream bowel dilation (HR 3.06, P < 0.0001), and younger age (19–29 years reference, 30–44 years, HR 0.83 [P = 0.40]; 45–59 years, HR 0.58 [P = 0.04], and 60+ years, HR 0.45 [P = 0.01]) to significantly increase the likelihood of ICR. A predictive nomogram for interval ICR was developed based on these significant variables.ConclusionsThe presence of CD strictures, penetrating complications, and upstream bowel dilation on CTE/MRE, combined with young age, significantly predict ICR. The suggested risk model may facilitate objective therapeutic decision-making.

  • Changes in Vedolizumab Utilization Across US Academic Centers and
           Community Practice Are Associated With Improved Effectiveness and Disease
    • Authors: Koliani-Pace J; Singh S, Luo M, et al.
      Pages: 1854 - 1861
      Abstract: AbstractBackgroundVedolizumab effectiveness estimates immediately after Food and Drug Administration (FDA) approval for ulcerative colitis (UC) and Crohn’s disease (CD) are limited by use in refractory populations. We aimed to compare treatment patterns and outcomes of vedolizumab in 2 time frames after FDA approval.MethodsWe used 2 data sets for time trend analysis, an academic multicenter vedolizumab consortium (VICTORY) and the Truven MarketScan database, and 2 time periods, May 2014–June 2015 (Era 1) and July 2015–June 2017 (Era 2). VICTORY cumulative 12-month clinical remission, corticosteroid-free remission, and mucosal healing rates, and Truven 12-month hospitalization and surgery rates, were compared between Eras 1 and 2 using time-to-event analyses.ResultsA total of 3661 vedolizumab-treated patients were included (n = 1087 VICTORY, n = 2574 Truven). In both cohorts, CD and UC patients treated during Era 2 were more likely to be biologic naïve. Compared with Era 1, Era 2 CD patients in the VICTORY consortium had higher rates of clinical remission (31% vs 40%, P = 0.03) and mucosal healing (42% vs 58%, P < 0.01). These trends were not observed for UC. In the Truven database, UC patients treated during Era 2 had lower rates of inflammatory bowel disease–related hospitalization (22.4% vs 9.6%, P < 0.001) and surgery (17.2% vs 9.4%, P = 0.008), which was not observed for CD.ConclusionSince FDA approval, remission and mucosal healing rates have increased for vedolizumab-treated CD patients, and vedolizumab-treated UC patients have had fewer hospitalizations and surgeries. This is likely due to differences between patient populations treated immediately after drug approval and those treated later.

  • Adalimumab or Infliximab for the Prevention of Early Postoperative
           Recurrence of Crohn Disease: Results From the ENEIDA Registry
    • Authors: Cañete F; Mañosa M, Casanova M, et al.
      Pages: 1862 - 1870
      Abstract: AbstractBackgroundAnti–tumor necrosis factor agents (anti-TNFs) are efficacious at preventing the postoperative recurrence (POR) of Crohn disease, as demonstrated in 2 randomized controlled trials. However, real-life data for infliximab or adalimumab in this setting are scarce. Our aim was to assess both the efficiency of anti-TNFs at preventing early POR of Crohn disease in clinical practice and the associated risk factors for POR.MethodsPatients in whom anti-TNFs were prescribed for the prevention of POR within 3 months after ileocolonic resection and who had an endoscopic assessment within 18 months were identified from the ENEIDA registry. Clinical and endoscopic features were collected within 18 months after surgery.ResultsIn total, 152 patients were included (55 treated with infliximab, 97 with adalimumab, and 39% with concomitant immunosuppressants). Anti-TNF treatment was started after a median time of 29 days (IQR 13–44) after surgery. Eighty-two percent of patients had at least one risk factor for POR, and 82% had been exposed to anti-TNFs before the index surgery. Overall, 34% had endoscopic POR (as defined using a Rutgeerts endoscopic score > i1); 14% had advanced endoscopic POR (>i2); and 20% had clinical POR, with no differences between infliximab and adalimumab. In the multivariate analysis, only perianal disease (odds ratio 2.73, 95% confidence interval [CI] 1.26–5.91) and rectal involvement (odds ratio 2.79, 95% CI 1.09–7.14) were independent predictors of endoscopic POR.ConclusionsIn clinical practice, anti-TNFs for the prevention of POR of Crohn disease are frequently used in patients experienced with anti-TNFs and with concomitant immunosuppressants. The efficacy of infliximab and adalimumab for POR prevention is similar and in accordance with the results obtained in randomized controlled trials.
