Abstract
INTRODUCTION The serum-based endoscopic healing index (EHI) test identifies endoscopic Crohn's disease (CD) activity. Data are lacking on the relationship between EHI with other endpoints. We assessed the relationship between EHI and the simplified Magnetic Resonance Index of Activity. MATERIALS AND METHODS Data were prospectively collected on patients with CD with either an EHI or fecal calprotectin (FCAL) within 90 days of magnetic resonance enterography (MRE). Diagnostic accuracy was assessed using area under the receiver operator characteristics. Proportions with any, severe, and terminal ileum MR inflammation were compared above/below identified thresholds for both EHI and FCAL. RESULTS A total of 241 MREs paired to either EHI or FCAL from 155 patients were included. Both EHI and FCAL had similar accuracy to diagnose inflammation (area under the receiver operator characteristics: EHI: 0.635 to 0.651, FCAL: 0.680 to 0.708). Optimal EHI values were 42 and 26 for inflammation on MRE and endoscopy, respectively. Patients with EHI ≥42 (100% vs. 63%, P =0.002), FCAL >50 µg/g (87% vs. 64%, P <0.001) and FCAL >250 µg/g (90% vs. 75%, P =0.02) had higher rates of simplified Magnetic Resonance Index of Activity ≥1 compared with lower values. EHI differentiated ileitis numerically more than FCAL (delta: 24% to 25% vs. 11% to 21%). Patients with FCAL ≥50 µg/g had higher rates of severe inflammation compared with FCAL <50 µg/g (75% vs. 47%, P <0.001), whereas smaller differentiation existed for EHI threshold of 42 (63% vs. 49%, P =0.35). CONCLUSION Both EHI and FCAL were specific in their confirmation of inflammation and disease activity on MRE in patients with CD. However, MRE-detected inflammation was frequently present in the presence of low EHI and FCAL in similar proportions.

Int Immunopharmacol 2024; 137:112506. [PMID: 38914032 DOI: 10.1016/j.intimp.2024.112506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 06/02/2024] [Accepted: 06/14/2024] [Indexed: 06/26/2024]
Abstract
AIMS Disease activity assessment and treatment outcome prediction are crucial in the patient management of ulcerative colitis (UC); yet the significance of platelet-to-lymphocyte percentage ratio (PLpR) remains unknown, which was investigated in this study. METHODS We used data from three clinical trials: ACT 1, PURSUIT, and UNIFI. In total, 7,614 endoscopic procedures and 1,365 patients were included for assessing severity and predicting outcome, respectively. The primary outcome was endoscopic remission, defined as a Mayo endoscopic score of 0. The diagnostic capacity of PLpR was evaluated by the area under the receiver operating characteristic curve (AUC) while multivariable logistic regression was employed to assess the prognostic power of PLpR. RESULTS PLpR showed higher AUCs than C-reactive protein in identifying endoscopic remission (P < 0.001) and improvement (P < 0.001). Besides, combining PLpR with fecal calprotectin enhanced the power to distinguish disease activity. In therapeutic outcome analyses, higher PLpR level indicated worse long-term outcomes. PLpR ≥ 1016.7 predicted a lower likelihood of endoscopic remission (OR: 0.50 [95 % CI: 0.39-0.65]; P < 0.001), endoscopic improvement (OR: 0.45 [95 % CI: 0.36-0.57]; P < 0.001), clinical remission (OR: 0.50 [95 % CI: 0.39-0.62]; P < 0.001), histologic improvement (OR: 0.50 [95 % CI: 0.31-0.79]; P = 0.004), and histologic-endoscopic mucosal improvement (OR: 0.42 [95 % CI: 0.27-0.66]; P < 0.001). Moreover, PLpR added the prognostic value to C-reactive protein, fecal calprotectin, clinical and endoscopic scores to predict long-term outcomes. CONCLUSION PLpR could be a promising biomarker for monitoring disease activity and predicting long-term therapeutic outcomes in UC.

Abstract
Value-based care focuses on improving the quality, effectiveness, and efficiency of health care while controlling costs. Low-value care implies services or interventions that provide little or no benefit to patients, have the potential to cause harm, incur unnecessary cost to patients, or waste limited health care resources. In this review, we discuss common instances of low-value care along the spectrum of management in inflammatory bowel diseases (IBD). These include low value care in: (1) diagnosis and monitoring of IBD: utilization of serological markers to screen and diagnose IBD, over-reliance on symptoms for monitoring disease, failure to employ treat-to-target strategies in symptomatic patients with IBD, and annual surveillance colonoscopies in patients at low risk of developing dysplasia; (2) treatment of IBD: use of 5-aminosalicylates in Crohn's disease, continuation of 5-aminosalicylates after escalation to immunosuppressive therapy, chronic corticosteroid use without steroid-sparing strategies, step therapy for Crohn's disease, failure to optimize tumor necrosis factor antagonists in patients with active disease and subsequently de-intensification of therapies in those who have achieved stable remission; and (3) management of hospitalized patients with IBD: routine cross-sectional imaging for patients with IBD presenting to the emergency department, withholding pharmacological prophylaxis for venous thromboembolism in patients hospitalized with IBD flare, and prolonged use of high-dose intravenous corticosteroids in patients with acute severe ulcerative colitis. This review is meant to bring attention to value-based care in IBD and provide guidance to treating practitioners. Future studies on systematic evaluation of high- and low-value care in patients with IBD are warranted.

Abstract
BACKGROUND Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBD) that contributes in part to irreversible bowel damage and long-term complications, reduced quality of life, invalidity, and economic burden. Suboptimal control of IBD is associated with higher healthcare resource utilization (HCRU), impaired quality of life (QoL), and reduced work productivity. AIMS The IBD-PODCAST study aimed to assess the proportion of IBD patients with suboptimal control and its associated impact. METHODS IBD-PODCAST is a cross-sectional, multicenter study that aimed to characterize the CD and UC population with optimal or suboptimal control according to the STRIDE-II criteria and patient- and physician-reported measures. Here we present the results of the Spanish cohort (n = 396). RESULTS A total of 104/196 (53.1%) CD and 83/200 (41.5%) UC patients were found to have suboptimal disease control. Long-term treatment targets according to STRIDE-II were applied in 172 (87.8%) CD and 181 (90.5%) UC patients. 125 of 172 (72.7%) CD and 74 of 181 (40.9%) UC patients were currently treated with targeted immunomodulators. Patients with CD and UC and suboptimal disease control showed impaired QoL, higher HCRU and direct costs, and also loss of work productivity compared to those with optimal control. CONCLUSION Despite a high rate of targeted immunomodulator therapy, a substantial proportion of IBD patients show suboptimal disease control according to the STRIDE II criteria. Those patients with suboptimal disease control exhibit impaired QoL, less work productivity, and higher HCRU, suggesting that there is considerable need for better treatment approaches in IBD.

Abstract
GOAL The objective of this study was to evaluate for potential predictors and etiologies of clinical relapse among patients with ulcerative colitis in deep remission. BACKGROUND Patients displaying deep (endoscopic and histologic) remission have a decreased cumulative risk of relapse in ulcerative colitis of <10% per year, but predictors and etiologies of relapse in this population are poorly understood. MATERIALS AND METHODS We performed a retrospective cohort study utilizing electronic medical records at Tufts Medical Center to identify patients in deep remission, classified as having both endoscopic remission (Mayo Endoscopic Score of 0 or 1) and histologic remission (Simplified Geboes Score 0.2). We evaluated the cumulative risk of clinical relapse following attainment of deep remission and examined predictors and etiologies of relapse. RESULTS Among 139 patients with ulcerative colitis in deep remission, the cumulative risk of relapse was <10% and <20% at 1 and 2 years. Patients with complete normalization of mucosa (Geboes=0) and normalization of C-reactive protein (<7.48 mg/dL) at the time of remission were associated with a lower risk of relapse. Discontinuation of therapy was the most commonly identified etiology of relapse. CONCLUSIONS Patients in deep remission have a 1-year risk of clinical relapse of <10%, with those demonstrating a non-normalized mucosa or elevated C-reactive protein predictive of persistent relapse risk. Discontinuation of therapy or minor histologic changes may drive relapse among those in deep remission.

Abstract
Increasing number of patients with ulcerative colitis (UC) have received biologic treatment during the last decade. The association between endoscopic healing (EH) and biologic treatment failure remains understudied. Medical information of UC patients who started biologic treatment was retrospectively collected. EH was defined as Mayo endoscopic subscore of 0 or 1. Loss of response (LOR)-free drug continuation rate was compared between patients who achieved EH and those who did not using Kaplan-Meier estimator. Fifty-two patients received 53 biologic treatments and underwent follow-up colonoscopies within 2 years. Thirty-three patients achieved EH, all of which remained on the same treatment without LOR during the observational period. Twenty patients did not achieve EH, 8 of which ultimately discontinued the treatment due to LOR to biologic agents. Kaplan-Meier estimator found a significantly lower drug continuation rate in patients without EH (p < 0.001; log-rank test). A Cox regression analysis identified EH as an independent factor associated with a reduced risk of LOR-related biologic treatment failure irrespective of the types of biologic agents (Hazard Ratio = 0.0324, p < 0.001). EH within 2 years is associated with a reduced risk of LOR-related biologic treatment failure in patients with UC.

Abstract
BACKGROUND Intestinal ultrasound (IUS) is an emerging modality in monitoring disease activity in ulcerative colitis (UC). Here, we aimed to identify early IUS predictors of treatment response as evaluated by endoscopy and assessed the kinetics of IUS changes. METHODS This prospective, longitudinal study included UC patients with endoscopic disease activity (endoscopic Mayo score [EMS] ≥2) starting anti-inflammatory treatment. Clinical scores, biochemical parameters and IUS were assessed at baseline (W0), at week 2 (W2), at W6(W6), and at the time of second endoscopy (W8-W26). Per colonic segment, endoscopic remission (EMS = 0), improvement (EMS ≤1), response (decrease in EMS ≥1), and clinical remission (Lichtiger score ≤3) were assessed and correlated with common IUS parameters. Additionally, drug-specific responsiveness of bowel wall thickness (BWT) was assessed. RESULTS A total of 51 patients were included and followed, and 33 patients underwent second endoscopy. BWT was lower from W6 onward for patients reaching endoscopic improvement (3.0 ± 1.2 mm vs 4.1 ± 1.3 mm; P = .026), remission (2.5 ± 1.2 mm vs 4.1 ± 1.1 mm; P = .002), and clinical remission (3.01 ± 1.34 mm vs 3.85 ± 1.20 mm; P = .035). Decrease in BWT was more pronounced in endoscopic responders (-40 ± 25% vs -4 ± 28%; P = .001) at W8 to W26. At W6, BWT ≤3.0 mm (odds ratio [OR], 25.13; 95% confidence interval, 2.01-3.14; P = .012) and color Doppler signal (OR, 0.35; 95% confidence interval, 0.14-0.88; P = .026) predicted endoscopic remission and improvement, respectively. Submucosal layer thickness at W6 predicted endoscopic remission (OR, 0.09; P = .018) and improvement (OR, 0.14; P = .02). Furthermore, BWT decreased significantly at W2 for infliximab and tofacitinib and at W6 for vedolizumab. CONCLUSIONS BWT and color Doppler signal predicted endoscopic targets already after 6 weeks of treatment and response was drug specific. IUS allows close monitoring of treatment in UC and is a surrogate marker of endoscopy.

J Clin Med 2023; 12:6796. [PMID: 37959261 PMCID: PMC10647216 DOI: 10.3390/jcm12216796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 10/14/2023] [Accepted: 10/20/2023] [Indexed: 11/15/2023] Open
Abstract
(1) Many patients with inflammatory bowel disease (IBD) in endoscopic remission have persistent histologic activity, which is associated with worse outcomes. There are limited data on the association between adalimumab drug concentrations and histologic outcomes using validated histologic indices. We aimed to assess the relationship between adalimumab concentrations and the Robarts Histopathology Index (RHI). (2) Patients from a tertiary IBD center from 2013 to 2020 with serum adalimumab (ADA) trough concentrations measured during maintenance therapy (≥14 weeks) and a colonoscopy or flexible sigmoidoscopy with biopsies performed within 90 days of drug level were included. Blinded histologic scoring using the RHI was performed. Primary analysis assessed the relationship between adalimumab drug concentrations and histologic remission using receiver operating characteristic curve analysis. (3) In 36 patients (26 Crohn's Disease, 9 ulcerative colitis, 1 indeterminate), median adalimumab concentrations were higher (17.3 ug/mL, 12.2-24.0) in patients with histologic remission compared to those without (10.3 ug/mL, 6.8-13.9, p = 0.008). The optimal ADA concentration identified using the Youden threshold was ≥16.3 ug/mL (sensitivity 70%, specificity 90%). Patients with ADA ≥ 16.3 ug/mL had higher histologic remission rates (78%) compared to lower ADA concentrations (14%, p= 0.002), as well as higher mucosal healing rates (86%) compared to lower levels (12%, p = 0.001). Symptoms correlated weakly and non-significantly with both histologic (RHI) scores (r = 0.25, p = 0.2) and adalimumab concentrations (r = 0.05, p = 0.8). (4) The current study demonstrated that higher serum adalimumab concentrations (≥16.3 ug/mL) are needed for histologic remission and mucosal healing assessed using the RHI.

Abstract
INTRODUCTION Endoscopic healing has been associated with improved long-term clinical outcomes in inflammatory bowel disease (IBD) and is a recommended target for treatment. Evidence is limited regarding real-world uptake and patterns of treat-to-target monitoring to assess endoscopic healing after treatment initiation. We aimed to estimate the proportion of patients in the Study of a Prospective Adult Research Cohort with IBD (SPARC IBD) who received colonoscopy in the 3-15 months after starting a new IBD treatment. METHODS We identified SPARC IBD patients who initiated a new biologic (infliximab, adalimumab, certolizumab pegol, golimumab, vedolizumab, and ustekinumab) or tofacitinib. We estimated the proportion of patients who received colonoscopies in the 3-15 months after IBD treatment initiation and described use by patient subgroups. RESULTS Among 1,708 eligible initiations from 2017 to 2022, the most common medications were ustekinumab (32%), infliximab (22%), vedolizumab (20%), and adalimumab (16%). The median patient age was 38 years, with 66% Crohn's disease; 55% were female, and 12% were non-White. In the 3-15 months after medication initiation, 49.3% (95% confidence interval 46.2%-52.5%) of initiations were followed by a colonoscopy. Colonoscopy use was similar between ulcerative colitis and Crohn's disease, but was higher among male patients, those older than 40 years, and those who received colonoscopy within 3 months of initiation. Colonoscopy use varied between study sites, from 26.6% (15.0%-38.3%) to 63.2% (54.5%-72.0%). DISCUSSION Approximately half of SPARC IBD patients received colonoscopy in the 3-15 months after initiation to a new IBD treatment, suggesting a low uptake of treat-to-target colonoscopy for the assessment of mucosal healing in real-world clinical practice. The variation in colonoscopy use between study sites suggests a lack of consensus and a need for more robust evidence around whether or not the practice of routine monitoring colonoscopy is associated with improved patient outcomes.

Pharmacoepidemiol Drug Saf 2023; 32:817-831. [PMID: 37144449 DOI: 10.1002/pds.5635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 03/31/2023] [Accepted: 04/30/2023] [Indexed: 05/06/2023]
Abstract
BACKGROUND Propensity score (PS) methods with two treatment groups (e.g., treated vs. control) is a well-established technique for reducing the effects of confounding in nonrandomized studies. However, researchers are often interested in comparing multiple interventions. PS methods have been modified to incorporate multiple exposures. We described available techniques for PS methods in multicategory exposures (≥3 groups) and examined their use in the medical literature. METHODS A comprehensive search was conducted for studies published in PubMed, Embase, Google Scholar, and Web of Science until February 27, 2023. We included studies using PS methods for multiple groups in general internal medicine research. RESULTS The literature search yielded 4088 studies (2616 from PubMed, 86 from Embase, 85 from Google Scholar, 1671 from Web of Science, five from other sources). In total, 264 studies using PS method for multiple groups were identified; 61 studies were on general internal medicine topics and included. The most commonly used method was that of McCaffrey et al., which was used in 26 studies (43%), where the Toolkit for Weighting and Analysis of Nonequivalent Groups (TWANG) method and corresponding inverse probabilities of treatment weights were estimated via generalized boosted models. The next most commonly used method was pairwise propensity-matched comparisons, which was used in 20 studies (33%). The method by Imbens et al. using a generalized propensity score was implemented in six studies (10%). Four studies (7%) used a conditional probability of being in a particular group given a set of observed baseline covariates where a multiple propensity score was estimated using a non-parsimonious multinomial logistic regression model. Four studies (7%) used a technique that estimates generalized propensity scores and then creates 1:1:1 matched sets, and one study (2%) used the matching weight method. CONCLUSIONS Many propensity score methods for multiple groups have been adopted in the literature. The TWANG method is the most commonly used method in the general medical literature.

Abstract
BACKGROUND Evaluation of mucosal healing with colonoscopy is recommended for inflammatory bowel disease (IBD) management; however, little is known about real-world use of treat-to-target monitoring following IBD treatment initiation. We aimed to estimate the proportion of U.S. commercially insured IBD patients who receive colonoscopy in the 3 to 15 months after initiating treatment. METHODS We identified IBD patients, 18 to 64 years of age, in the IBM MarketScan Commercial Claims and Encounters database as those with ≥3 IBD diagnoses prior to initiation of biologic, small molecule, or immunomodulatory treatment. We excluded patients with prior colectomy and with rheumatologic and other indications for these therapies. Colonoscopies were identified using International Classification of Diseases-Ninth Revision, International Classification of Diseases-Tenth Revision, and Current Procedural Terminology procedure codes. We used Kaplan-Meier methods to estimate the proportion of newly treated IBD patients who received colonoscopy in the 3 to 6 months, 3 to 12 months, and 3 to 15 months following treatment initiation, and stratified trends by year, patient age and sex, and region. RESULTS From 2013 to 2019, we identified 39 734 initiators of IBD medications (51.9% female, mean age 39.4 years). We observed similar colonoscopy incidence among ulcerative colitis patients (3-6 months: 14.2% [95% confidence interval (CI), 13.6%-14.8%]; 3-12 months: 37.7% [95% CI, 36.8%-38.6%]; 3-15 months: 46.1% [95% CI, 45.2%-47.1%]) and Crohn's disease patients (3-6 months: 11.2% [95% CI, 10.8%-11.6%]; 3-12 months: 32.2% [95% CI, 31.5%-32.9%]; 3-15 months: CD: 40.1% [95% CI, 39.3%-40.8%]). Overall colonoscopy use was slightly higher among women, patients in the Northeast, and those initiating newer biologic therapies. CONCLUSIONS Fewer than half of newly treated IBD patients underwent colonoscopy within 3 to 15 months of initiating new treatment, suggesting low uptake of treat-to-target endoscopic disease monitoring in real-world practice.

Abstract
BACKGROUND The Endoscopic Healing Index (EHI) is a serum biomarker panel that can predict endoscopic inflammation in Crohn's disease (CD). METHODS Paired serum samples with endoscopies from adult patients participating in a prospective biobank (June 2014 to December 2018) were analyzed post hoc. Diagnostic performance for EHI was assessed against the individual parameters of the Simple Endoscopic Score for CD using previously identified cutoffs. Confounders for EHI performance were identified using logistic regression. RESULTS A total of 205 CD patients were included (50% male, median age 37 years). An EHI of 20 points was sensitive for ruling out any ulcers (85%; 95% confidence interval [CI], 77%-91%) and large (5-20 mm) or very large (>20 mm) ulcers (93%; 95% CI, 84%-97%). An EHI of 50 points was specific for ruling in any ulcers (86%; 95% CI, 76%-92%) and large or very large ulcers (87%; 95% CI, 79%-92%). After accounting for total extent of inflamed mucosa, strictures, and disease location, each 20-point increase in EHI was associated with a 1.7-fold increased probability for the presence of large or very large ulcers (adjusted odds ratio, 1.7; 95% CI, 1.1-2.6). CONCLUSIONS The EHI was independently associated with ulcer size and accurately identified large or very large ulcers. A cutoff of 50 points can reliably rule in mucosal ulcers and allow for treatment adjustment. A cutoff of 20 points can reliably rule out mucosal ulcers and signal completion of treatment adjustment algorithms.

Abstract
Background Strategies incorporating objective disease monitoring in Crohn's disease (CD), beyond clinical symptoms are important to improve patient outcomes. Little evidence exists to explore patient understanding of CD treatment goals, nor preferences and experiences with monitoring options. This qualitative study aimed to explore patient experiences and preferences of CD monitoring to inform monitoring strategies, improve patient engagement, and optimize a patient-centered approach to care. Methods This study used a patient-oriented, qualitative descriptive design. Convenience and snowball sampling were used to recruit adult participants diagnosed with CD who had experience with at least 2 types of disease monitoring. Online focus groups were conducted and data were analyzed using thematic analysis. Results This international study included 37 participants from Australia, Canada, United Kingdom, and the United States. Overall, participants preferred more noninvasive types of monitoring [eg, intestinal ultrasound (IUS)] but were willing to undergo more invasive monitoring (eg, colonoscopy) if required. To improve disease monitoring, participants wanted increased access to IUS, establishment of a patient-centered interdisciplinary team and access to information and self-testing. Participants identified challenges with communication between patients and providers and stressed the importance of participating in shared decision making and being equal team members in their care. Conclusions It is imperative to incorporate patient-driven preferences into how we can best structure monitoring strategies, to ensure equitable access to those preferred modalities and embrace a shared decision-making approach to disease management in CD.

Abstract
BACKGROUND & AIMS Biomarkers are used frequently for noninvasive monitoring and treatment decision making in the management of patients with ulcerative colitis (UC). This American Gastroenterological Association (AGA) guideline is intended to support practitioners in decisions about the use of biomarkers for the management of UC. METHODS A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, and conduct an evidence synthesis on the clinical performance of serum C-reactive protein (CRP), fecal calprotectin, and fecal lactoferrin as biomarkers of disease activity in patients with established UC in symptomatic remission or with active symptoms. The guideline panel used the Evidence-to-Decision framework to develop recommendations for the use of biomarkers for monitoring and management of UC and provided implementation considerations for clinical practice. RESULTS The guideline panel made 7 conditional recommendations. In patients with UC in symptomatic remission, the panel suggests the use of a biomarker- and symptom-based monitoring strategy over a symptom-based monitoring strategy. For patients in symptomatic remission, the panel suggests using fecal calprotectin <150 μg/g, normal fecal lactoferrin, and/or normal CRP to rule out active inflammation and avoid routine endoscopic assessment of disease. In patients with UC with moderate to severe symptoms, the panel suggests using fecal calprotectin >150 μg/g, elevated fecal lactoferrin, or elevated CRP to inform treatment decisions and avoid routine endoscopic assessment of disease. However, in patients in symptomatic remission but elevated biomarkers, and in patients with moderate to severe symptoms with normal biomarkers, the panel suggests endoscopic assessment of disease to inform treatment decisions. In patients with UC with mild symptoms, the panel suggests endoscopic assessment of disease activity to inform treatment decisions. The panel identified the use of a biomarker-based monitoring strategy over an endoscopy-based monitoring strategy as a knowledge gap. The panel also proposed key implementation considerations for optimal use of biomarkers, and identified areas for future research. CONCLUSIONS In patients with UC, noninvasive biomarkers, including fecal calprotectin, fecal lactoferrin, and serum CRP can inform disease monitoring and management.

Abstract
Background Endoscopic healing is an established treatment target for ulcerative colitis (UC). We have recently validated the Milan ultrasound criteria (MUC) to assess endoscopic activity in UC; a MUC score > 6.2 is a valid cut‐off to discriminate endoscopic activity (Mayo endoscopic subscore > 1). Objective The aim of this study was to assess the predictive value of MUC on disease course in a prospective cohort of UC patients. Methods UC patients regardless of disease activity and current therapy, underwent colonoscopy and bowel ultrasound (US) at baseline in a blinded fashion. Correlations between baseline MUC and Mayo endoscopic subscore were assessed using Spearman's rank correlation. UC‐related negative course (defined as the need for corticosteroids, or treatment escalation, or hospitalization, or need for colectomy: a composite outcome) over a median 20 months follow‐up, was investigated using the Kaplan‐Meier method and Cox regression analysis. Results 98 UC patients were followed up for a median time of 1.6 years (IQR 0.9¬2.7). Milan ultrasound criteria and Mayo endoscopic subscore significantly correlated at baseline (ρ = 0.653; p < 0.001). 70 patients (71%) had negative disease course during the follow‐up period. Milan ultrasound criteria > 6.2 at baseline was statistically significantly associated with negative disease course (HR: 3.87, 95% CI: 2.25–6.64, p < 0.001). Kaplan–Meier analyses drawed a statistically significantly lower cumulative probability of treatment escalation, need of corticosteroids, hospitalization and colectomy, among patients who had MUC ≤ 6.2 at baseline as compared to patients with MUC > 6.2 (p < 0.05 for all outcomes). Conclusion we have demonstrated for the first time the value of bowel US and an US score in predicting disease course in UC. Milan ultrasound criteria, a validated US‐based score, predicts disease course in UC. Milan ultrasound criteria ≤ 6.2 may be the new treatment target to achieve to reduce the risk of worse outcomes.

Abstract
Background Inflammatory bowel disease (IBD) treatment paradigms recommend objective disease activity assessment and reactive therapeutic drug monitoring (TDM) prior to changes in biologic therapy. We aimed to describe objective marker and TDM assessment in routine clinical practice prior to biologic therapeutic changes in adult IBD patients.
Methods TARGET-IBD is a prospective longitudinal cohort of over 2100 IBD patients receiving usual care at 34 US academic or community centers enrolled between June 2017 and October 2019 who received biologic therapy and had a dose change or biologic discontinuation for lack of efficacy. Objective markers of disease activity within 12 weeks prior included fecal calprotectin, C-reactive protein (CRP), endoscopy, computed tomography (CT) and magnetic resonance imaging (MRI). TDM data for infliximab or adalimumab was obtained. Results 525 patients (71.4% Crohn’s disease [CD], 28.6% ulcerative colitis [UC]) receiving biologic therapy underwent dose change (55.6%) or discontinuation (44.4%) for lack of efficacy. The majority were Caucasian (85.7%), 18–39 years old (52.2%), privately insured (81.5%), and at academic centers (73.7%). For dose changes, 67.5% had at least one objective disease activity assessment or TDM in the 12 weeks prior (CD 67.9%, UC 66.2%; P = 0.79). The most common objective marker was CRP in both CD (39.1%) and UC (54.5%). CRP and calprotectin were used significantly more in UC (P = 0.02 and P = 0.03). TDM was obtained in 30.7% (28.8% UC, 31.4% CD; P = 0.72) prior to dose change. For biologic discontinuation, 79.4% patients underwent objective assessment or TDM prior. In CD, CRP (46.3%) was most common, and CT (P = 0.03) and MRI (P < 0.001) were significantly more frequent than in UC. TDM was performed in 40.1% of patients (43.5% UC, 38.0% CD, P = 0.49) prior to discontinuation. Among all participants with dose change or discontinuation, endoscopy was performed in 29.3% with CD and 31.3% with UC. Academic care setting was associated with objective assessment before therapy change (OR 1.59, 95% CI 1.01–2.50). Conclusion Nearly one-third of patients undergoing a biologic dose change or discontinuation do not undergo objective disease activity assessment or TDM. Assessment choice differs by disease. Future studies assessing the impact of such practices on long-term outcomes are needed.

Abstract
BACKGROUND & AIMS Endoscopic improvement is an important treatment target for mild-to-moderate ulcerative colitis (UC). However, early endoscopic evaluation is not always feasible. We aimed to develop a clinical decision support tool to discriminate patients who have achieved endoscopic improvement from those with more severe inflammation following mesalamine induction therapy. METHODS We performed a post-hoc analysis of data from a phase 3 non-inferiority trial of 726 adults with mild-to-moderate UC treated with mesalamine. Multivariable logistic regression modeling determined associations between candidate variables and endoscopic improvement (Mayo endoscopic subscore=0-1 according to blinded central reading) at Week 8. Internal model validation was performed using bootstrap resampling. A clinical decision support tool was developed to stratify patients into low, intermediate, and high probability groups for endoscopic improvement. RESULTS Variables associated with endoscopic improvement at Week 8 included 50% reduction in fecal calprotectin from baseline (odds ratio [OR] 2.64, 95% CI:, 1.81, 3.85), reduction in rectal bleeding (OR 1.79 per point reduction, 95% CI: 1.35, 2.39), and improvement in physician global assessment (OR 2.32 per point improvement, 95% CI: 1.88, 2.85). The baseline Geboes score (OR 0.74 per grade, 95% CI: 0.65, 0.85) and prolonged disease duration (OR 0.95 per year, 95% CI: 0.92, 0.98) were negatively associated with endoscopic improvement. This model strongly discriminated endoscopic improvement in the development dataset (area under the curve [AUC] 0.84, 95% CI: 0.81, 0.87) and during validation (AUC 0.83). CONCLUSIONS We developed and validated a clinical decision support tool that has good discriminative performance for induction of endoscopic improvement in patients with mild-to-moderate UC treated with mesalamine. ClinicalTrials.gov Registration: NCT01903252.

Prealbumin and Retinol-Binding Protein 4: The Promising Inflammatory Biomarkers for Identifying Endoscopic Remission in Crohn's Disease. J Inflamm Res 2022; 14:7371-7379. [PMID: 34992423 PMCID: PMC8715867 DOI: 10.2147/jir.s343125] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 12/09/2021] [Indexed: 12/21/2022] Open
Abstract
Objective Endoscopic remission is the primary therapeutic target and associated with clinical outcome in Crohn’s disease (CD). Non-invasive and accurate biomarkers are important in monitoring endoscopic remission frequently. Our study aimed at investigating the predictive capacity of prealbumin and retinol-binding protein 4 (RBP4) for identifying endoscopic remission. Methods From June 2018 to December 2020, 515 endoscopy procedures (332 in the training cohort and 183 in the validation cohort) were enrolled in this multicentre retrospective cohort study. Blood samples were collected for prealbumin or RBP4 testing with 7 days before the endoscopy. A simple Endoscopic Score for CD (SES-CD) was performed to evaluate endoscopic activity and defined endoscopic remission. The area under receiver operating characteristic curve (AUROC), sensitivity, specificity, positive predictive value and negative predictive value were performed to assess the predictive capacity of the biomarkers. Results Serum concentration of prealbumin and RBP4 was demonstrated to be higher in patients with endoscopic remission and significantly negatively correlated with SES-CD in the training cohort. The AUROC of prealbumin and specificity of prealbumin and RBP4 were larger than that of C-reactive protein in the training cohort and the validation cohort. The model combining prealbumin and faecal calprotectin had the largest AUROC (0.842 [95% CI: 0.775–0.908]). Furthermore, in both cohorts, prealbumin had a larger AUROC than C-reactive protein for identifying endoscopic remission in patients with anti-tumour necrosis factor therapy. Conclusion Prealbumin and RBP4 were promising biomarkers for identifying endoscopic remission, especially in patients with anti-tumour necrosis factor therapy.

Abstract
BACKGROUND Crohn's disease is a progressive inflammatory bowel disease. Persistent untreated inflammation can cumulatively result in bowel damage in the form of strictures, fistulas, and fibrosis, which can ultimately result in the need for major abdominal surgery. Mucosal healing has emerged as an attractive, yet ambitious goal in the hope of preventing long-term complications. SUMMARY Clinical remission is an inadequate measure of disease activity. Noninvasive markers such as fecal calprotectin, CRP, or small bowel ultrasound are useful adjunct tools. However, endoscopic assessment remains the cornerstone in building a treatment plan. Achieving complete mucosal healing has proved to be an elusive goal even in the ideal setting of a clinical trial. KEY MESSAGES Aiming for complete mucosal healing in all patients may result in overuse of medications, higher costs, and potential side effects of aggressive immunosuppressive treatment. More practical goals such as relative or partial healing, for example, 50% improvement in inflammation and reduction in size of ulcers, ought to be considered, particularly in difficult-to-treat populations.

Role of Biomarkers in the Diagnosis and Treatment of Inflammatory Bowel Disease. Life (Basel) 2021; 11:life11121375.

Abstract
The number of patients with inflammatory bowel disease (IBD) is increasing worldwide. Endoscopy is the gold standard to assess the condition of IBD. The problem with this procedure is that the burden and cost on the patient are high. Therefore, the identification of a reliable biomarker to replace endoscopy is desired. Biomarkers are used in various situations such as diagnosis of IBD, evaluation of disease activity, prediction of therapeutic effect, and prediction of relapse. C-reactive protein and fecal calprotectin have a lot of evidence as objective biomarkers of disease activity in IBD. The usefulness of the fecal immunochemical test, serum leucine-rich glycoprotein, and urinary prostaglandin E major metabolite have also been reported. Herein, we comprehensively review the usefulness and limitations of biomarkers that can be used in daily clinical practice regarding IBD. To date, no biomarker is sufficiently accurate to replace endoscopy; however, it is important to understand the characteristics of each biomarker and use the appropriate biomarker at the right time in daily clinical practice.

A Patient Self-Made Point-of-Care Fecal Test Improves Diagnostic Accuracy Compared with Fecal Calprotectin Alone in Inflammatory Bowel Disease Patients. Diagnostics (Basel) 2021; 11:diagnostics11122323.

Abstract
Background: Monitoring inflammatory bowel disease patients may be challenging. Fecal calprotectin is one of the most performed tests. Other fecal biomarkers are less used in clinical practice. Rapid fecal tests that could be performed by patients may be a useful strategy to closely monitor disease activity. Methods: We performed a prospective observational study including consecutive inflammatory bowel disease patients referred for colonoscopy in a single center. Certest FOB + Transferrin + Calprotectin + Lactoferrin® (Certest Biotec S.L, Zaragoza, Spain), a one-step point-of-care test which simultaneously detects these four biomarkers was performed. Endoscopic inflammatory activity was defined using the Mayo score (≥1) in ulcerative colitis, SES-CD (>3) and Rutgeerts scores (≥1) for Crohn’s disease. Results: Out of a total of 106 patients (56.5% female, mean age 51 years), 54 (50.9%) were diagnosed with ulcerative colitis and 52 (49.1%) with Crohn’s disease. Endoscopic activity was detected in 42 patients (39.0%). Fecal calprotectin provided the best sensitivity (97.6%), with limited specificity (34.4%). Compared to calprotectin, the other 3 fecal biomarkers showed better specificity (87.5–92.1%) and lower sensitivity (45.2–59.5%). Patients with a negative result in all biomarkers (19/106—17.9%) had 100% (CI 95% 97.4–100) negative predictive value, while patients with the 4 biomarkers positive (13/106—12.3%) had 100% (CI 95% 96.1–100) positive predictive value of endoscopic inflammatory activity. AUROC of this 4 biomarker point-of-care test was 0.845 (95% CI 0.771–0.920), significantly higher than the AUROCs of any of the 4 biomarkers. Conclusions: This test may be a useful strategy to monitor inflammatory activity in clinical practice by excluding or prioritizing patients in need of a colonoscopy.

Treatment Targets in Ulcerative Colitis: Is It Time for All In, including Histology? J Clin Med 2021; 10:jcm10235551.

Abstract
The main therapeutic goal of ulcerative colitis (UC) is to induce and maintain remission to prevent long-term disease progression. Treat-to-target strategies, first introduced by the STRIDE consensus and updated in 2021, have shifted focus from symptomatic control toward more stringent objective endpoints. Today, patient monitoring should be based on a combination of biomarkers and clinical scores, while patient-reported outcomes could be used as short-term targets in monitoring disease activity and therapeutic response. In addition, endoscopic healing was the preferred long-term goal in UC. A Mayo endoscopic score (MES) ≤ 1 can be recommended as a minimum target. However, recent evidence suggests that more stringent endoscopic goals (MES of 0) are associated with superior outcomes. Recently, emerging data support that histological remission (HR) is a superior prognostic factor to endoscopic healing in predicting long-term remission. Despite not yet being recommended as a target, HR may become an important potential therapeutic goal in UC. However, it remains questionable if histological healing should be used as a routine assessment in addition to clinical, biomarker, and endoscopic targets in all patients. Therefore, in this review, our aim was to discuss the current evidence for the different treatment targets and their value in everyday clinical practice.

Understanding Determinants of Patient Preferences Between Stool Tests and Colonoscopy for the Assessment of Disease Activity in Inflammatory Bowel Disease. Dig Dis Sci 2021; 66:2564-2569.

Abstract
BACKGROUND AND AIMS Evidence is now available in support of using fecal biomarkers to monitor disease activity in inflammatory bowel disease (IBD). Patient adherence is often cited as a barrier to implementation. We assessed patient determinants for using stool tests to monitor disease activity. METHODS Prospective interview of IBD patients using an analytic hierarchy matrix survey built to understand preferences for choosing between stool testing or colonoscopy for monitoring disease activity, after considering different test criteria (accuracy, preparation, pain, complications). Theoretical thresholds of misclassification were posed to patients to see how they might consider shifting from colonoscopy to stool testing. RESULTS A total of 100 patients (n = 51 CD, n = 46 male) were interviewed with median age and disease duration of 44 years (IQR 27-63) and 9 years (IQR 5-21), respectively. Stool-based testing was preferred over colonoscopy by 60% initially; however, a majority of participants changed their choice to colonoscopy after learning more about the diagnostic performance of currently available stool tests for disease monitoring (p < 0.001). Across all sub-groups, accuracy was ranked as the top criterion when choosing between stool-based testing and colonoscopy for disease activity assessments. Most patients were willing to choose stool-based testing over colonoscopy for disease monitoring if the stool test was wrong at most 1 in 20 times (5% misclassification rate). DISCUSSION Accuracy is the most important criteria for IBD patients when choosing monitoring strategies, and a high degree of confidence is required of stool test results for patients to choose this strategy.

Abstract
Background and Aims Therapeutic drug monitoring (TDM) with measurement of serum drug and antidrug antibody concentrations is used to optimize tumor necrosis factor antagonists (anti-TNF). The endoscopic healing index (EHI) is a validated serum-based assay to measure mucosal inflammation in adults with Crohn disease (CD). Our objectives were to evaluate the relationship between EHI and TDM results and to determine the anti-TNF concentration range associated with EHI <20 (consistent with endoscopic remission). Methods Adult and pediatric patients with CD (N = 1731) were selected retrospectively from a clinical laboratory cohort. Patients were selected if they had an ICD-10 code for CD and if results for EHI and TDM were available within 30 days of each other. The relationship between EHI and TDM results was examined and the anti-TNF concentration range associated with EHI <20 vs >50 was evaluated. Results Median anti-TNF concentration was higher in patients with EHI <20 vs >50 for infliximab (N = 796): 11.1 vs 3.4 µg/mL and for adalimumab (N = 935): 9.2 vs 5.0 µg/mL (P < 0.0001 both drugs). Patients with antibodies to infliximab (12.8%) or adalimumab (14.9%) had lower anti-TNF concentrations (P < 0.001 both drugs) and higher EHI (P < 0.01 both drugs). The concentration range for infliximab: 5-15 µg/mL (5-9 µg/mL in pediatric patients) and for adalimumab: 5-10 µg/mL (8 µg/mL in pediatric patients) best discriminated EHI <20 vs >50. Conclusions We report the anti-TNF concentration range associated with EHI <20. Combined testing of EHI and TDM is proposed as a noninvasive approach for treat-to-target management which could improve the ability to monitor disease and optimize anti-TNF therapy.

Abstract
Background Inflammatory bowel disease (IBD) care is beset with substantial practice variation. Learning health systems (LHSs) aim to learn from this variation and improve quality of care by sharing feedback and improvement strategies within the LHS. Obtaining accurate information on outcomes and quality of care is a priority for LHS, which often includes patients' self-reported data. While prior work has shown that patients can accurately report their diagnosis and surgical history, little is known about their ability to self-report recent healthcare utilization, medication use, and vaccination status. Methods We compared patient self-reported data within the IBD Qorus LHS regarding recent IBD-related emergency department (ED) visits, hospitalizations, computerized tomography (CT) scans, corticosteroid use, opioid use, influenza vaccinations, and pneumococcal vaccinations with electronic health record (EHR) data. Results We compared 328 patient self-reports to data extracted from the EHR. Sensitivity was moderate-to-high for ED visits, hospitalizations, and CT scans (76%, 87%, and 87%, respectively), sensitivity was lower for medication use with 71% sensitivity for corticosteroid use and only 50% sensitivity for self-reported use of opioids. Vaccinations were reported with high sensitivity, but overall agreement was low as many patients reported vaccinations that were not registered in the EHR. Conclusions Self-reported IBD-related ED visits, hospitalizations, and CT scans are reported with high sensitivity and accuracy. Medication use, and in particular opioid use, is less reliably reported. Vaccination self-report is likely more accurate than EHR data as many vaccinations are not accurately registered.

Serum biomarkers confirming stable remission in inflammatory bowel disease. Sci Rep 2021; 11:6690.

Abstract
Crohn's disease (CD) and ulcerative colitis (UC) have a chronic-remittent course. Optimal management of inflammatory bowel diseases (IBD) relies on early intervention, treat-to-target strategies and a tight disease control. However, it is challenging to assess the risk of relapses in individual patients. We investigated blood-based biomarkers for the confirmation of disease remission in patients with IBD. We retrospectively analyzed samples of 40 IBD patients (30 UC, 10 CD) enrolled in a tight-control follow-up study. Half of the patients had a flare during follow up. Serum was analyzed for S100A12 as well as S100A8/A9 and for 50 further biomarkers in a bead-based multiplex assay. The concentrations of 9 cytokines/chemokines and S100A8/A9 significantly differed in IBD patients with unstable remission (before flares) when compared to IBD patients with stable remission. Although the number of patients was small, ROC curve analyses revealed a number of biomarkers (IL-1β, IL-1RA, IL-8, IL13, IL-15, IL-21, IL-25, IFN-β, CXCL9, CXCL10, CXCL11, Galectin-1, G-CSF and S100A8/A9) that were elevated in patients with later occurring relapses. While earlier studies on peripheral biomarkers in IBD are limited to only few analytes, our study using a broad screening approach identified serum biomarkers with the potential to indicate unstable disease control in IBD, which may help to steer individual therapies to maintain remission.

We aimed to investigate an effective CBC parameter and explore its impact on disease activity in a large CD cohort. METHODS We performed a retrospective analysis of patients with established CD who underwent clinically indicated endoscopy at four tertiary centres in China between 2016 and 2020. Individual variables of the Simple Endoscopic Score for CD, CBC parameters, C-reactive protein (CRP) levels, erythrocyte sedimentation rate, and faecal calprotectin (FC) were independently reviewed by different investigators. The hold-out method was used to verify the predictive power of the established model. RESULTS Data from a total of 1388 endoscopic procedures performed for 882 eligible CD patients were available with routine blood parameters and related indicators. The model using platelet-to-lymphocyte percentage ratio (PLpR) had high accuracy for identifying patients in endoscopic remission (ER), with an area under the curve (AUC) of 0.785 [95% confidence interval (CI): 0.784-0.787], which was comparable with that for CRP (AUC: 0.775, 95% CI: 0.774-0.777). Notably, the AUC of PLpR was significantly higher than that of CRP in patients with colonic disease and with a history of surgery. Moreover, after combining the FC with PLpR, the AUC value of FC + PLpR increased up to 0.892 (95% CI: 0.890-0.894) for identifying ER. CONCLUSIONS We explored an index (PLpR) to identify CD patients in ER based on platelet and lymphocyte percentage from the CBC. PLpR helped evaluate the degree of disease activity and monitor the therapeutic response.

Abstract
With the advent of biologic and small molecule therapies, there has been a substantial change in the treatment of inflammatory bowel disease. These advances have had a great impact in preventing disease progression, intestinal damage and, therefore, have contributed to a better quality of life. Discordance between symptom control and mucosal healing has been demonstrated. This has led to the search for new disease control targets. The treat to target strategy, based on expert recommendations and now a randomized controlled trial, has determined that clinical and endoscopic remission should be the goal of therapy. Biomarkers (fecal calprotectin) can be a surrogate target. Although histological healing has shown benefits, there is inadequate evidence and inadequate therapy for that to be a fixed goal at this time. This review will focus on therapeutic goals, according to the evidence currently available, and evaluate strategies to achieve them.

Incorporating Fecal Calprotectin Into Clinical Practice for Patients With Moderate-to-Severely Active Ulcerative Colitis Treated With Biologics or Small-Molecule Inhibitors.

Abstract
INTRODUCTION We applied the Grading of Recommendations, Assessment, Development, and Evaluation framework to evaluate the performance of fecal calprotectin (FC) as an alternative to endoscopy in patients with moderate-to-severe ulcerative colitis (UC) treated with a biologic agent or tofacitinib. METHODS Individual participant data from the trials of infliximab, golimumab, vedolizumab, and tofacitinib for UC were pooled to generate prevalence of endoscopic activity (Mayo endoscopy score) across different combinations of the rectal bleeding score (RBS) and stool frequency score (SFS). These estimates were then combined with the data from an updated systematic review of the operating properties of FC to generate clinical scenario-specific assessments of the performance of FC as a predictor of endoscopic disease activity. A prespecified threshold of acceptability for false-negative (FN) and false-positive (FP) test results was set at 5%. RESULTS For patients with UC achieving RBS 0 + SFS 0/1, FC ≤ 50 μg/g may avoid endoscopy in 50% patients with a FN rate <5%. Similarly, for patients with RBS 2/3 + SFS 2/3, FC ≥ 250 μg/g potentially avoids endoscopy in approximately 50% patients with an FP rate <5%. The greatest uncertainty in the diagnostic performance for FC was observed in patients with UC achieving RBS 0 but having SFS 2/3, where FN and FP rates were consistently >10%, and endoscopic evaluation may be warranted. DISCUSSION Two clinical scenarios were identified where FC can be used with confidence for monitoring treatment response to biologics or tofacitinib in patients with UC without the requirement for endoscopy.

Abstract
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.
