Utility of the MARS-5 in Assessing Medication Adherence in IBD

Abstract Introduction We aimed to validate the Medication Adherence Report Scale-5 (MARS-5) as a tool for assessing medication adherence in inflammatory bowel disease (IBD) and to determine predictors of medication adherence. Methods One hundred twelve (N = 112) adults with confirmed IBD participating in the longitudinal Manitoba Living With IBD Study were eligible. Demographics, IBD type, surgeries, disease activity (using the Inflammatory Bowel Disease Symptom Inventory and fecal calprotectin levels), perceived stress, and medication use were collected biweekly through online surveys. The MARS-5 scores were obtained at baseline and at 1 year. Correlation between medication monitoring data and MARS-5 scores was performed and the optimal MARS-5 cutoff point for adherence assessment determined. Predictors of medication adherence were assessed at both ≥90% and ≥80%. Results Participants were predominantly female (71.4%), mean age was 42.9 (SD = 12.8), and the majority (67.9%) had Crohn disease (CD). Almost half (46.4%) were taking more than 1 IBD medication, with thiopurines (41.9%) and biologics (36.6%) the most common. Only 17.9% (n = 20) were nonadherent at a <90% level; of those, 90% (n = 18) were using oral medications. The MARS-5 was significantly associated with adherence based on medication monitoring data at baseline (r = 0.48) and week 52 (r = 0.57). Sensitivity and specificity for adherence ≥80% and ≥90% were maximized at MARS-5 scores of >22 and >23, respectively. Having CD (OR = 4.62; 95% confidence interval, 1.36-15.7) was the only significant predictor of adherence. Conclusion MARS-5 is a useful measure to evaluate adherence in an IBD population. In this highly adherent sample, disease type (CD) was the only predictor of medication adherence.

Objective: Fecal calprotectin (FC) is a promising marker for assessment of inflammatory bowel disease (IBD) activity. However, the utility of FC for predicting mucosal healing (MH) of IBD patients has yet to be clearly demonstrated. The objective of our study was to perform a meta-analysis evaluating the diagnostic accuracy of FC in predicting MH of IBD patients. Methods: We systematically searched the databases for studies from inception to April 2020 that evaluated MH in IBD. The methodological quality of each study was assessed according to the Quality Assessment of Diagnostic Accuracy Studies checklist. The extracted data were pooled using a summary receiver operating characteristic curve model. Random-effects model was used to summarize the diagnostic odds ratio, sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio. Results: Sixteen studies comprising 1,682 ulcerative colitis (UC) patients and 4 studies comprising 221 Crohn’s disease (CD) patients were included. The best performance of FC for predicting MH in UC was at cut-off range of 60–75 μg/g with area under the curve (AUC) of 0.88 and pooled sensitivity and specificity of 0.87 and 0.79, respectively. The pooled sensitivity and specificity values of cutoff range 180–250 μg/g for predicting MH in CD were 0.67 and 0.76, respectively. The AUC of 0.79 also revealed improved discrimination for identifying MH in CD with FC concentration. Conclusion: Our meta-analysis has found that FC is a simple, reliable noninvasive marker for predicting MH in IBD patients. FC cutoff range 60–75 μg/g appears to have the best overall accuracy in UC patients.

AbstractIn the search for improved stool biomarkers for inflammatory bowel disease (IBD), an aptamer-based screen of 1129 stool proteins was conducted using stool samples from an IBD cohort. Here we report that of the 20 proteins subsequently validated by ELISA, stool Ferritin, Fibrinogen, Haptoglobin, Hemoglobin, Lipocalin-2, MMP-12, MMP-9, Myeloperoxidase, PGRP-S, Properdin, Resistin, Serpin A4, and TIMP-1 are significantly elevated in both ulcerative colitis (UC) and Crohn’s disease (CD) compared to controls. When tested in a longitudinal cohort of 50 UC patients at 4 time-points, fecal Fibrinogen, MMP-8, PGRP-S, and TIMP-2 show the strongest positive correlation with concurrent PUCAI and PGA scores and are superior to fecal calprotectin. Unlike fecal calprotectin, baseline stool Fibrinogen, MMP-12, PGRP-S, TIMP-1, and TIMP-2 can predict clinical remission at Week-4. Here we show that stool proteins identified using the comprehensive aptamer-based screen are superior to fecal calprotectin alone in disease monitoring and prediction in IBD.

Abstract Background This multicenter prospective study (UMIN000019958) aimed to evaluate the usefulness of serum leucin-rich alpha-2 glycoprotein (LRG) levels in monitoring disease activity in inflammatory bowel disease (IBD). Methods Patients with moderate-to-severe IBD initiated on adalimumab therapy were enrolled herein. Serum LRG, C-reactive protein (CRP), and fecal calprotectin (fCal) levels were measured at week 0, 12, 24, and 52. Colonoscopy was performed at week 0, 12, and 52 for ulcerative colitis (UC), and at week 0, 24, and 52 for Crohn’s disease (CD). Endoscopic activity was assessed using the Simple Endoscopic Score for Crohn’s Disease (SES-CD) for CD and the Mayo endoscopic subscore (MES) for UC. Results A total of 81 patients was enrolled. Serum LRG levels decreased along with improvements in clinical and endoscopic outcomes upon adalimumab treatment (27.4 ± 12.6 μg/ml at week 0, 15.5 ± 7.7 μg/ml at week 12, 15.7 ± 9.6 μg/ml at week 24, and 14.5 ± 6.8 μg/ml at week 52), being correlated with endoscopic activity at each time point (SES-CD: r = 0.391 at week 0, r = 0.563 at week 24, r = 0.697 at week 52; MES: r = 0.534 at week 0, r = 0.429 at week 12, r = 0.335 at week 52). Endoscopic activity better correlated with LRG compared to CRP and fCal on pooled analysis at all time points (SES-CD: LRG: r = 0.636, CRP: r = 0.402, fCal: r = 0.435; MES: LRG: r = 0.568, CRP: 0.389, fCal: r = 0.426). Conclusions Serum LRG is a useful biomarker of endoscopic activity both in CD and UC during the adalimumab treatment.

Background:Аnkylosing Spondylitis (AS) is closely associated with inflammatory bowel disease (IBD). About 6-46% of patients with IBD have various lesions of the musculoskeletal system [1]. 5-10% of patients with spondylarthritis (SpA) eventually develop IBD, with Crohn’s disease (CD) being more common than Ulcerative colitis (UC) [2]. Determining the level of fecal calprotectin (FC) is a study that allows to diagnose IBD. The concentration of FC directly depends on the neutrophil infiltration of the intestinal mucosa and has a direct connection with the activity of the inflammatory process [3]. It is known that level of FC increases in 2/3 of patients with AS and is closely related to parameters reflecting higher disease activity [4].Objectives:The aim of this study was to evaluate the frequency of IBD in patients with AS using an assessment of FC level.Methods:In the analysis were included 40 patients with AS, fulfilling the modified New York criteria, among them man -26 (65%), woman -14 (35%), mean age of patients was 41.2 ±10.5, mean disease duration - 13±8.8 years. All patients were examined with ESR, CRP, esophagogastroduodenoscopy, colonoscopy and quantitative analysis of the fecal calprotectin levels using the method of lateral immunochromatography with the BUHLMANN Quantum Blue rapid test. Standart range: 100-1800 µg /g.Results:All patients had a high disease activity, mean BASDAI was 5.2 ± 1.7, mean ASDAS CRP 3.8 ± 1.1. 35 patients (87.5 %) had FC level more than 100 µg / g, the remaining 5 patients (12.5%) less than 100 µg /g. 12 patients (30 %) had FC level more than 1,800 µg / g, 23 (57.5 %) from 101 µg / g to 1800 µg / g. All patients with FC levels more than 100 µg / g showed an increase CRP (mean 28.4 mg / l) and ESR (mean 36.3 mm\h) levels. IBD were diagnosed in 9 cases (22.5%): 5 patients (12.5 %) with CD and 4 patients (10 %) - UC, in the remaining cases (77.5%) was no intestinal pathology.Conclusion:The results showed high frequency of IBD in patients with AS. Patients with high FC levels (more than 100 μg/g) had high disease activity (AS). In most cases, inflammatory bowel disease were diagnosed in patients with FC levels more than 100 µg/g.References:[1] Bernstein CN, Blanchard JF, Rawsthorne P, Yu N.

Background and aims: Early prediction of the effect of vedolizumab (VDZ) in inflammatory bowel disease (IBD) is of paramount importance to guide clinical decisions. This study assessed whether early fecal calprotectin (FC) can predict endoscopic response and histologic remission after VDZ initiation. Methods: This was a prospective study. Inclusion criteria were endoscopic inflammation and FC >100 µg/g. FC was determined at baseline and weeks 2, 4, 8 and 16. At week 16, endoscopies with ileal and colonic biopsies were performed. FC changes were assessed with Wilcoxon Rank Sum tests. ROC statistics were used to assess the diagnostic accuracy of FC. Results: In total, 45 patients [27 Crohn’s disease (CD), 16/2 ulcerative colitis (UC)/IBD-unclassified] [40% males, median age 39 (28–51) years] were included. Week 16 endoscopic response and histologic remission rates were 58% and 33%. A median 37% decline in FC at week 2 was observed only in endoscopic responders, p = 0.025. FC <250 µg/g at week 8 predicted endoscopic response in both UC and CD (positive predictive value 100%), whereas absence of FC decline at week 8 corresponded with absence of endoscopic response in CD [negative predictive value (NPV) 82%] and absence of histologic remission in both UC and CD (NPV 90%). Conclusion: The onset of a decline in FC as early as week 2 is associated with endoscopic response to VDZ induction. FC <250 µg/g at week 8 is associated with endoscopic response, whereas absence of FC decline at week 8 is associated with absence of both endoscopic response and histologic remission. FC levels 8 weeks after the start of VDZ could be used to guide clinical decisions and might substitute for endoscopic response evaluation.
