Abstract
Managing inflammatory bowel disease (IBD) is becoming increasingly complex and personalized, considering the advent of new advanced therapies with distinct mechanisms of action. Achieving mucosal healing (MH) is a pivotal therapeutic goal in IBD management and can prevent IBD progression and reduce flares, hospitalization, surgery, intestinal damage, and colorectal cancer. Employing proactive disease and therapy assessment is essential to achieve better control of intestinal inflammation, even if subclinical, to alter the natural course of IBD. Periodic monitoring of fecal calprotectin (FC) levels and interval endoscopic evaluations are cornerstones for evaluating response/remission to advanced therapies targeting IBD, assessing MH, and detecting subclinical recurrence. Here, we comment on the article by Ishida et al Moreover, this editorial aimed to review the role of FC and endoscopic scores in predicting MH in patients with IBD. Furthermore, we intend to present some evidence on the role of these markers in future targets, such as histological and transmural healing. Additional prospective multicenter studies with a stricter MH criterion, standardized endoscopic and histopathological analyses, and virtual chromoscopy, potentially including artificial intelligence and other biomarkers, are desired.

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
Fecal calprotectin (FC) levels correlate with the disease activity of inflammatory bowel diseases (IBD); however, the utility of FC in predicting IBD relapse remains to be determined. We aim to evaluate the efficacy of fecal calprotectin in predicting the relapse of inflammatory bowel disease. We searched Pubmed (MEDLINE), Embase, Web of Science, and the Cochrane library databases up to 7 July 2021. Our study estimated the pooled sensitivity and specificity, summary receiver operating characteristic (SROC) curve, and the optimal cut-off value for predicting IBD relapse using a multiple threshold model. A total of 24 prospective studies were included in the meta-analysis. The optimal FC cut-off value was 152 μg/g. The pooled sensitivity and specificity of FC was 0.720 (0.528 to 0.856) and 0.740 (0.618 to 0.834), respectively. FC is a useful, non-invasive, and inexpensive biomarker for the early prediction of IBD relapse. An FC value of 152 μg/g is an ideal threshold to identify patients with a high relapse probability.

[PMID: 36769791 PMCID: PMC9918267 DOI: 10.3390/jcm12031142] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/02/2023] [Accepted: 01/29/2023] [Indexed: 02/04/2023] Open
Abstract
The i Support Therapy-Access to Rapid Treatment (iSTART) was an initiative to improve patient-centered management in mild-to-moderate ulcerative colitis (UC). Our aim was to update the iSTART recommendations in order to include fecal calprotectin (FC) in the monitoring of patients with UC and improve their management. Twelve physicians from nine countries worldwide attended a virtual international consensus meeting on 4 May 2022. Data from three systematic reviews were analyzed, and a new systematic review investigating all studies reporting measurement of FC at home was conducted. Based on literature evidence, statements were formulated, discussed, and approved by voting. Statements were considered approved if at least 75% of participants agreed with a proposed statement. Fourteen statements were approved. Based on this consensus, FC measurement should be routinely performed for monitoring patients with mild-to-moderate UC to identify disease relapses early and initiate an appropriate treatment. Further studies are needed to assess whether self-monitoring of FC is associated with better disease control and improved patients' quality of life.

Abstract
PURPOSE Vedolizumab (VDZ) was reported to be effective as a first-line biological in adult ulcerative colitis (UC). The aim of this study was to investigate the safety and effectiveness of VDZ as the first-line biological in pediatric refractory UC. METHODS We retrospectively extracted data from pediatric patients with UC who received first-line VDZ. The following were recorded: baseline characteristics; clinical activity of intestinal disease, levels of fecal calprotectin (FC), C-reactive protein, and serum amyloid A; and erythrocyte sedimentation rate. Clinical effectiveness, biochemical remission, and safety of VDZ were also investigated. FINDINGS Eight patients were identified (median age, 12 years). FC levels were abnormal in all cases and were remarkably elevated in 3 patients. C-reactive protein, serum amyloid A, and erythrocyte sedimentation rate values were abnormal in 2, 4, and 5 patients, respectively. According to the pediatric UC activity index score, 1, 5, and 2 patients had mild, moderate, and severe disease. Fourteen weeks after VDZ administration, 5 patients achieved remission, and 3 remained in remission until week 52. Of the 3 patients who did not reach remission in week 14, two achieved remission by week 52. In week 52, five of the eight patients continued receiving VDZ and maintained remission. All patients achieved clinical remission without corticosteroid use. No adverse events were observed in any patient. IMPLICATIONS VDZ may serve as a safe and effective first-line biological option for treating pediatric patients with UC. FC levels before VDZ administration may be predictive of long-term remission.

Abstract
Inflammatory bowel disease (IBD) is a chronic immune-mediated inflammation of the gastrointestinal tract with a highly heterogeneous presentation. It has a relapsing and remitting clinical course that necessitates lifelong monitoring and treatment. Although the availability of a variety of effective therapeutic options including immunomodulators and biologics (such as TNF, CAM inhibitors) has led to a paradigm shift in the treatment outcomes and clinical management of IBD patients, some patients still either fail to respond or lose their responsiveness to therapy over time. Therefore, according to the recent Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE-II) recommendations, continuous disease monitoring from symptomatic relief to endoscopic healing along with short- and long-term therapeutic responses are critical for providing IBD patients with a tailored therapy algorithm. Moreover, considering the high unmet need for novel therapeutic approaches for IBD patients, various new modulators of cytokine signaling events (for example, JAK/TYK inhibitors), inhibitors of cytokines (for example IL-12/IL-23, IL-22, IL-36, and IL-6 inhibitors), anti-adhesion and migration strategies (for example, β7 integrin, sphingosine 1-phosphate receptors, and stem cells), as well as microbial-based therapeutics to decolonize the bed buds (for example, fecal microbiota transplantation and bacterial inhibitors) are currently being evaluated in different phases of controlled clinical trials. This review aims to offer a comprehensive overview of available treatment options and emerging therapeutic approaches for IBD patients. Furthermore, predictive biomarkers for monitoring the therapeutic response to different IBD therapies are also discussed.

Abstract
Background and objectives: Ulcerative colitis is a chronic recurrent intestinal inflammatory disease, and its recurrence is difficult to predict. In this review, we summarized the objective indicators that can be used to evaluate intestinal inflammation, the purpose is to better predict the clinical recurrence of UC, formulate individualized treatment plan during remission of UC, and improve the level of diagnosis and treatment of UC.Methods: Based on the search results in the PUBMED database, we explored the accuracy and value of these methods in predicting the clinical recurrence of UC from the following three aspects: endoscopic and histological scores, serum biomarkers and fecal biomarkers.Results: Colonoscopy with biopsy is the gold standard for assessing intestinal inflammation, but it is invasive, inconvenient and expensive. At present, there is no highly sensitive and specific endoscopic or histological score to predict the clinical recurrence of UC. Compared with serum biomarkers, fecal biomarkers have higher sensitivity and specificity because they are in direct contact with the intestine and are closer to the site of intestinal inflammation. Fecal calprotectin is currently the most studied and meaningful fecal biomarker. Lactoferrin and S100A12, as novel biomarkers, have no better performance than FC in predicting the recurrence of UC.Conclusions: FC is currently the most promising predictive marker, but it lacks an accurate cut-off value. Combining patient symptoms, incorporating multiple indicators to construct a UC recurrence prediction model, and formulating individualized treatment plans for high recurrence risk patients will be the focus of UC remission management.

Abstract
The timing of colonoscopy in patients with active ulcerative colitis (UC) lacks coherence. The published guidelines and recommendations advocate time-bound colonoscopy in patients with active UC to assess for mucosal healing. However, the practice of performing colonoscopies at fixed time frames lacks reasoning. The time to achieve mucosal healing in UC is not uniform across the patient populations and is influenced by the disease severity and efficacy and time to therapeutic response of the drugs being used. Additionally, with the availability of sensitive noninvasive inflammatory biomarkers such as fecal calprotectin, that parallel the disease activity and correlate with mucosal healing, the notion of performing colonoscopy at fixed intervals sounds unjustifiable. The authors express their view that a response-guided colonoscopy (driven by normalization of clinical symptoms and inflammatory biomarkers), rather than a time-bound colonoscopy, would be more logical, apart from being cost-effective and patient-friendly.

Abstract
The 2021 National report from IBD UK included responses from over 10 000 patients with inflammatory bowel disease, over 70% of whom reported having at least one flare in the last 12 months. As the first-line treatment for patients with mild and moderate ulcerative colitis, the action and delivery mechanisms of mesalazine are crucial for successful management of the disease. The choice of the most appropriate formulation of mesalazine and securing patient concordance and adherence to treatment remains a challenge for healthcare professionals. This article details the outcome of a roundtable discussion involving a group of gastroenterology consultants and specialist nurses which considered the importance of ensuring that patients have individualised mesalazine therapy before escalation to other treatments and gives recommendations for the management of patients with mild or moderate ulcerative colitis.

Abstract
The incidence of inflammatory bowel diseases (IBD) emerged with Westernisation of dietary habits worldwide. Crohn's disease and ulcerative colitis are chronic debilitating conditions that afflict individuals with substantial morbidity and challenge healthcare systems across the globe. Since identification and characterisation of calprotectin (CP) in the 1980s, faecal CP emerged as significantly validated, non-invasive biomarker that allows evaluation of gut inflammation. Faecal CP discriminates between inflammatory and non-inflammatory diseases of the gut and portraits the disease course of human IBD. Recent studies revealed insights into biological functions of the CP subunits S100A8 and S100A9 during orchestration of an inflammatory response at mucosal surfaces across organ systems. In this review, we summarise longitudinal evidence for the evolution of CP from biomarker to rheostat of mucosal inflammation and suggest an algorithm for the interpretation of faecal CP in daily clinical practice. We propose that mechanistic insights into the biological function of CP in the gut and beyond may facilitate interpretation of current assays and guide patient-tailored medical therapy in IBD, a concept warranting controlled clinical trials.

Abstract
Aminosalicylates (5-ASA) are used as the first-line maintenance treatment in patients with mild-moderate ulcerative colitis (UC). Early identification of patients at high risk for 5-ASA non-response and appropriate therapeutic escalation are essential to avoid disease progression. However, the absence of a standardized definition for treatment success makes this a challenging task. The focus of the current review was to describe the risk factors and management strategies associated with 5-ASA non-response. Rates of 5-ASA failure can vary from 17 % to 75 % according to different success definitions, of which clinical relapse is the most prevalent and studied condition. Younger age and endoscopic activity at diagnosis, extensive colitis, early need for corticosteroids, elevated inflammatory markers and non-adherence are consistent risk factors of 5-ASA failure. Given the effectiveness, safety profile and tolerability of this medication, therapy optimization is critical before treatment escalation. Combined use of systemic and topical therapy at an appropriate dose in a once-daily administration and control of adherence could improve success rates.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract mainly comprising two forms including Crohn's disease (CD) and ulcerative colitis (UC). IBD is a lifelong relapsing remitting disease and relapses occur at random patterns which are unpredictable. Fecal biomarkers have been increasingly used to assess disease activity in IBD due to their positive correlations with intestinal inflammation. Recent studies have also assessed the use of fecal biomarkers in predicting relapse and post-operative recurrence. This review provides information from global studies of using fecal calprotectin, lactoferrin and S100A12 to predict relapse in IBD. Strategies for further studies and the use of these fecal biomarkers for personalized management in IBD are also discussed.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronically relapsing disease with a continuous need for proactive monitoring to decide appropriate treatments and follow-up strategies. To date, gastrointestinal endoscopy with histologic examination of biopsies and contrast-enhanced imaging are mandatory techniques for the diagnosis and the activity assessment of IBD. SUMMARY In recent decades, many research efforts in the IBD field have been placed on finding non-invasive and reliable biomarkers of disease burden that can be easily tested in body fluids without impacting the quality of life of patients. Unfortunately, the ideal biomarker is yet to be discovered and recent studies have investigated the possibility to increase the accuracy of such measurements by combining different markers. In this review, we provide an update about the current knowledge on biomarkers of intestinal inflammation in IBD, focussing on disease diagnosis, correlation with endoscopic findings, and prediction of relapse. We also summarize composite scores of clinical and laboratory markers that have been recently proposed in various scenarios of disease activity. Key Messages: To date, only C-reactive protein and faecal calprotectin can be considered reliable markers of disease activity with demonstrated utility in IBD management. The combination of different parameters has recently shown higher accuracy and might substitute single-marker approaches in the future of research and clinical practice.

Abstract
OBJECTIVES In 2015, the Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) program proposed shifting the therapeutic focus on ulcerative colitis (UC) toward altering the natural history of the disease course by regularly monitoring objective measurements of disease activity and tailoring treatment accordingly. The therapeutic paradigm shift was well received in the research community and is often cited. However, new evidence on optimal UC treatment targets continues to accumulate since the time of the STRIDE guidelines. This systematic review summarizes the evidence accrued since the STRIDE UC recommendations, discusses the barriers for adoption of treat-to-target approaches in clinical practice in UC, and suggests directions for future research. METHODS We systematically reviewed MEDLINE for studies from the time of the STRIDE systematic review up to March 31, 2018, that assessed the potential treatment targets identified by the STRIDE recommendations. RESULTS Each potential treatment target literature search returned > 200 articles, which were then reviewed by 2 independent investigators for relevant studies. Selected studies of clinical factors, patient-reported outcomes, endoscopy, histology, imaging, and biomarkers and implications on treatment targets are summarized. CONCLUSIONS It appears that the relative weight given to different therapeutic targets in the development and improvement of UC treatments could be optimized, with an increased emphasis on endoscopic and histological targets over clinical or symptomatic targets. For this evolution to occur, however, new research has to demonstrate that the treat-to-target approach will deliver on the promise of better long-term outcomes compared with current approaches.

Abstract
The clinical course of ulcerative colitis (UC) is featured by remission and relapse, which remains unpredictable. Recent studies revealed that fecal calprotectin (FC) could predict clinical relapse for UC patients in remission, which has not yet been well accepted. To detect the predictive value of FC for clinical relapse in adult UC patients based on updated literature, we carried out a comprehensive electronic search of PubMed, Web of Science, Embase, and the Cochrane Library to identify all eligible studies. Diagnostic accuracy including pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and pooled area under the receiver operating characteristic (AUROC) was calculated using a random effects model. Heterogeneity across studies was assessed by the I 2 metric. Sources of heterogeneity were detected using subgroup analysis. Metaregression was used to test potential factors correlated to DOR. Publication bias was assessed using Deek's funnel plots. In our study, 14 articles enrolling a total of 1110 participants were finally included, and all articles underwent a quality assessment. Pooled sensitivity, specificity, PLR, and NLR with 95% confidence intervals (CIs) were 0.75 (95% CI: 0.70-0.79), 0.77 (95% CI: 0.74-0.80), 3.45 (95% CI: 2.31-5.14), and 0.37 (95% CI: 0.28-0.49) respectively. The area under the summary receiver operating characteristic (sROC) curve was 0.82, and the diagnostic odds ratio was 10.54 (95% CI: 6.16-18.02). Our study suggested that FC is useful in predicting clinical relapse for adult UC patients in remission as a simple and noninvasive marker.

Abstract
The current goals of treatment in inflammatory bowel disease, both Crohn's disease and ulcerative colitis, are to achieve clinical, endoscopic and ideally histological remission and improve the quality of life of these patients. Current therapies are effective in achieving remission in most cases, but there is a lack of clear guidelines on their optimal duration. This review aims to evaluate the current evidence on the withdrawal of therapy with 5-aminosalicylates, thiopurines and methotrexate. We also aim to identify which specific group of patients, while in remission and in the absence of risk factors, may be able to discontinue therapy without a significant risk of relapse.

Abstract
Introduction There is variability in the fecal calprotectin (FCP) cut‐off level for the prediction of ulcerative colitis (UC) disease activity and differentiation from irritable bowel disease (IBS‐D). The FCP cut‐off levels vary from country to country. Aims We aimed to assess FCP as a marker of disease activity in patients with UC. We determined the optimal FCP cut‐off value for differentiating UC and IBS‐D. Methods In a prospective study, we enrolled 76 UC and 30 IBS‐D patients. We studied the correlation of FCP with disease activity/extent as well as its role in differentiating UC from IBS‐D. We also reviewed literature regarding the optimal FCP cut‐off level for the prediction of disease activity and differentiation from IBS‐D patients. Results Sensitivity, specificity, positive predictive value, and negative predictive value of FCP (cut‐off level, 158 μg/g) for the prediction of complete mucosal healing (using Mayo endoscopic subscore) were 90, 85, 94.7, and 73.3%, respectively. Sensitivity, specificity, positive predictive value, and negative predictive value of FCP (cut‐off level, 425 μg/g) for the prediction of inactive disease (Mayo Score ≤ 2) were 94.3, 88.7, 86.2, and 95.4%, respectively. We also found a FCP cut‐off value of 188 μg/g for the differentiation of UC from IBS‐D. Conclusions The study reveals the large quantitative differences in FCP cut‐off levels in different study populations. This study demonstrates a wide variation in FCP cut‐off levels in the initial diagnosis of UC as well as in follow‐up post‐treatment. Therefore, this test requires validation of the available test kits and finding of appropriate cut‐off levels for different study populations.

Abstract
BACKGROUND Fecal biomarkers are emerging tools in the assessment of mucosal healing in inflammatory bowel diseases (IBD). GOALS We aimed to evaluate the accuracy of fecal matrix metalloprotease-9 (MMP-9) and fecal lipocalin-2 (LCN-2) compared with calprotectin in detecting endoscopic activity in IBD STUDY:: Overall, 86 IBD adults underwent colonoscopy consecutively and prospectively, with Crohn's disease Endoscopic Index of Severity (CDEIS) in Crohn's disease (CD) patients or Mayo endoscopic subscore calculation for ulcerative colitis (UC) patients, and stool collection. Fecal calprotectin was measured using quantitative immunochromatographic testing. Fecal MMP-9 and LCN-2 was quantified by enzyme-linked immunosorbent assay. MMP-9 and LCN-2 thresholds were determined using receiver operating curves. RESULTS In 54 CD patients, fecal calprotectin, MMP-9 and LCN-2 correlated with CDEIS and were significantly increased in patients with endoscopic ulcerations. MMP-9 >350 ng/g detected endoscopic ulceration in CD with a sensitivity of 90.0% and a specificity of 63.6%, compared with fecal calprotectin >250 μg/g (sensitivity=90.5% and specificity=59.1%). Fecal LCN-2 demonstrated lower performances than the 2 other biomarkers (sensitivity=85.7% and specificity=45.5%).In 32 UC patients, fecal MMP-9, LCN-2, and calprotectin levels were significantly increased in patients with endoscopic activity. In UC patients, fecal MMP-9 >900 ng/g had the best efficacy to detect endoscopic activity (sensitivity=91.0% and specificity=80.0%, compared with fecal calprotectin >250 μg/g (sensitivity=86.4% and specificity=80.0%) and LCN-2 >6700 ng/g (sensitivity=82.0% and specificity=80.0%). CONCLUSIONS Fecal MMP-9 is a reliable biomarker in detecting endoscopic activity in both UC and CD patients.

Abstract
Background Calprotectin is a stable neutrophil protein, which can be measured in faecal samples. The faecal level of calprotectin increases during disease activity in ulcerative colitis (UC). Nonetheless, the relevance of faecal calprotectin (FC) measurement during granulomonocytapheresis (GMA) for UC has not yet been fully evaluated. This prospective study was to investigate the value of FC for assessing disease activity and predicting clinical course in UC patients undergoing GMA therapy. Methods One hundred and eighty-four patients with moderately active UC with endoscopic activity (Mayo endoscopic subscore [MES] = 2 or 3) received Adacolumn GMA therapy (10 apheresis sessions over consecutive 5 weeks). Patients who achieved clinical remission were subsequently given maintenance medications for 12 months. FC levels were measured at entry and after treatment. Results After GMA, 80 of the 184 patients (43%) achieved clinical remission, and 51 (28%) achieved mucosal healing (MH; MES = 0 or 1). The median FC level significantly decreased in patients who achieved MH (P = 0.02), but not in those without MH. Thirty-four patients (43%) relapsed during the 12-month follow-up. The median FC level at the end of GMA therapy was significantly higher in patients who subsequently relapsed than in those who maintained remission (149.5 vs 45.5 μg/g, P < 0.001). A cut off value of 114 μg/g had a sensitivity of 76% and a specificity of 85% to predict future relapse. Conclusions Our findings indicate that FC is a relevant biomarker, which is convenient to measure for assessing endoscopic activity and predicting relapse in patients who achieve remission following a course of GMA therapy.

Abstract
PURPOSE OF REVIEW We discuss the newest evidence-based data on management of ulcerative colitis (UC). We emphasize risk-stratification, optimizing medical therapies, and surgical outcomes of UC. RECENT FINDINGS Recent medical advances include introduction of novel agents for UC. Vedolizumab, an anti-adhesion molecule, has demonstrated efficacy in moderate to severe UC. Tofacitinib, a small molecule, has also demonstrated efficacy. Data on optimization of infliximab show the superiority of combination therapy with azathioprine over monotherapy with infliximab or azathioprine alone. Data on anti-tumor necrosis factor-alpha (anti-TNF) therapeutic drug monitoring also hold promise, as do preliminary data on the dose escalation of infliximab in severe hospitalized UC. Surgical outcome data are reassuring, with new fertility data showing the effectiveness of in vitro fertilization. UC management is multi-disciplinary and changing. While novel therapies hold promise, better optimization of our current arsenal will also improve outcomes.

Abstract
Inflammatory bowel disease (IBD) is a chronic, idiopathic inflammatory disease of gastrointestinal tract with waxing and waning clinical course, which may lead to irreversible bowel damage and a loss of bowel function. Cumulative intestinal damage results in complications such as stricture or fistulae, and eventually a large number of IBD patients undergo surgery. Notably, even during remission period (no clinical symptoms), subclinical inflammation often persists and the disease continues to progress. Therefore, the therapeutic target of IBD has been evolving from symptomatic control to mucosal healing to prevent structural intestinal damage. To achieve therapeutic goals in IBD, it is important to optimize therapy according to disease severity and response to treatment. Therefore, monitoring disease activity is recommended throughout the disease course of IBD. Especially strategies to monitor disease beyond symptoms through endoscopy, laboratory markers, and imaging is required.

Abstract
Clinically effective therapies now exist for remission maintenance in both ulcerative colitis [UC] and Crohn's Disease [CD]. For each major class of IBD medications [5-aminosalicyclates, immunomodulators, and biologic agents], used alone or in combination, there is a risk of relapse following reduction or cessation of treatment. A consensus expert panel convened by the European Crohn's and Colitis Organisation [ECCO] reviewed the published literature and agreed a series of consensus practice points. The objective of the expert consensus is to provide evidence-based guidance for clinical practice so that physicians can make informed decisions in partnership with their patients. The likelihood of relapse with stopping each class of IBD medication is reviewed. Factors associated with an altered risk of relapse with withdrawal are evaluated, and strategies to monitor and allow early identification of relapse are considered. In general, patients in clinical, biochemical, and endoscopic remission are more likely to remain well when treatments are stopped. Reintroduction of the same treatment is usually, but not always, successful. The decision to stop a treatment needs to be individualized, and shared decision making with the patient should take place.

Abstract
Ileocolonoscopy is the gold standard for the diagnosis and assessment of postoperative recurrence in Crohn's disease (CD). Nevertheless, endoscopy is time-consuming and invasive. A minimally invasive and simple screening test would improve patient adherence to examination and provide greater clinical benefit. A number of fecal biomarkers have been evaluated for their utility for the diagnosis and monitoring of inflammatory bowel disease as alternative tests to endoscopy. Area covered: In this review, we focused on the utility of fecal biomarkers in the management of postoperative CD. Our major endeavor was to present an evidence-based assessment of the results of clinical trials on the available data. A literature search was conducted using the Medline. Expert commentary: Calprotectin and lactoferrin, both neutrophil-derived proteins, are the two most frequently used fecal biomarkers in clinical trials and practice. Several studies evaluated the role of these fecal biomarkers in patients with postoperative CD. These studies suggest that fecal calprotectin, and to a lesser degree lactoferrin, are useful in assessing endoscopic severity and in predicting future clinical recurrence after resection for CD. However, large scale, well-designed studies are necessary to rigorously evaluate the role of fecal biomarkers in postoperative CD.

Abstract
OBJECTIVE To evaluate the predictive value of fecal calprotectin (FC) for clinical relapse in Chinese patients with quiescent Crohn's disease (CD) and to further investigate the correlation between FC and intestinal inflammation. METHODS Sixty-two patients with a diagnosis of quiescent CD were consecutively enrolled in this prospective study. Fecal samples were collected and enteroscopy were performed to detect mucosal lesions at the beginning of the study. Patients were followed until the first relapse or by the end of the two-year follow-up. The calprotectin concentration was measured using a quantitative enzyme-linked immunoassay. RESULTS Of the 62 CD patients, 29 had a relapse (median time of relapse: 8.44 months). The median follow-up months was 8.16 (4.98-13.59). The cut off level of 225 μg/g provided the maximal area under the receiver operating characteristic curve (AUC) of .775 for detecting the relapse of CD patients. Meanwhile, fecal occult blood had an added value. The multivariate Cox regression model showed that FC was the strongest predictor of the risk of relapse (risk ratio (RR): 6.315; p = .001). FC correlated most closely with the simple endoscopic score for Crohn's disease (SES-CD) (r = 0.524, p < .001). CONCLUSIONS FC correlated significantly with gut inflammation and could be a reliable predictor of relapse in Chinese patients with CD.

Abstract
BACKGROUND Objective control of intestinal inflammation during inflammatory bowel disease (IBD) is becoming the main driver for medical treatment. However, the monitoring tools-related burden remains poorly investigated. We aimed to evaluate their comparative acceptability and utility according to patients with IBD. METHODS After a preliminary phase, the final questionnaire encompassing self-administered and physician questionnaires was prospectively and consecutively submitted to 916 patients with IBD from 20 public and private centers. Acceptability and utility visual analog scales (VAS) were expressed as median with interquartile range. RESULTS Regarding the group of patients with Crohn's disease (n = 618), venipuncture (VAS = 9.3 [8.8-9.7]) and ultrasonography (VAS = 9.3 [8.7-9.7]) were the most acceptable tools (P < 0.0001, for each comparison), whereas rectosigmoidoscopy was the least acceptable tool (VAS = 4.4 [1.2-7.3]) (P < 0.0001, for each comparison). Wireless capsule endoscopy (VAS = 8.5 [5.2-9.3]), magnetic resonance enterocolonography (VAS = 8.0 [5.0-9.2]), and stools collection (VAS = 7.7 [4.6-9.3]) were more acceptable than colonoscopy (VAS = 6.7 [4.3-8.9]) (P < 0.0001, for each comparison). The acceptability was assessed in 298 patients with ulcerative colitis for venipuncture (VAS = 9.4 [8.8-9.7]), stools collection (VAS = 8.1 [5.7-9.4]), colonoscopy (VAS = 7.5 [4.7-9.2]), and rectosigmoidoscopy (VAS = 6.7 [2.8-9.1]); (P < 0.001 for each comparison). All monitoring tools were considered as highly useful by patients with IBD. Decreased acceptability was related to embarrassment for the collection/transport of stools (60.7%), bowel cleansing (76.3%) for colonoscopy, abdominal discomfort (51.3%) and rectal enema (36.6%) for rectosigmoidoscopy, bowel distension (48.3%) for magnetic resonance enterocolonography, and potential capsule retention (21.4%) for wireless capsule endoscopy. CONCLUSIONS Among the IBD monitoring tools, endoscopy demonstrated the lowest acceptability supporting the development of alternative modalities. Patients' information and examination conditions should be improved to ensure proper monitoring adherence.

Abstract
BACKGROUND Ulcerative proctitis (UP) presents distinctive clinical characteristics, outcomes and therapeutic approaches as compared to left-sided and extensive ulcerative colitis (UC). AIM To describe the current therapeutic requirements and clinical outcomes in patients with active UP. METHODS Retrospective observational study conducted in a referral IBD centre. Patients with UP in follow-up between 1989 and 2014 were included. The clinical characteristics, as well as the different treatments and drug formulations administered to treat flares, were recorded. RESULTS Out of 687 UC patients, 101 patients (15%) with UP were included. Median follow-up was 8 years (IQR 3-14) and 49% of patients presented disease activity during the study period. Topical mesalazine monotherapy (90%) was the most commonly administered treatment for disease activity (mostly as suppositories), followed by topical steroids (47%) and oral mesalazine (56%) in monotherapy or combination therapy. Only 14% and 16% of patients required oral prednisone and beclomethasone, respectively. CONCLUSIONS In clinical practice, active UP presents mostly favourable outcomes. Mesalazine suppositories are by far the most used treatment for these patients.

Abstract
BACKGROUND In asymptomatic patients with inflammatory bowel disease (IBD), "monitoring" involves repeated testing aimed at early recognition of disease exacerbation. We aimed to determine the usefulness of repeated fecal calprotectin (FC) measurements to predict IBD relapses by a systematic literature review. METHODS An electronic search was performed in Medline, Embase, and Cochrane from inception to April 2016. Inclusion criteria were prospective studies that followed patients with IBD in remission at baseline and had at least 2 consecutive FC measurements with a test interval of 2 weeks to 6 months. Methodological assessment was based on the second Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) checklist. RESULTS A total of 1719 articles were identified; 193 were retrieved for full text review. Six studies met eligibility for inclusion. The time interval between FC tests varied between 1 and 3 months. Asymptomatic patients with IBD who had repeated FC measurements above the study's cutoff level had a 53% to 83% probability of developing disease relapse within the next 2 to 3 months. Patients with repeated normal FC values had a 67% to 94% probability to remain in remission in the next 2 to 3 months. The ideal FC cutoff for monitoring could not be identified because of the limited number studies meeting inclusion criteria and heterogeneity between selected studies. CONCLUSIONS Two consecutively elevated FC values are highly associated with disease relapse, indicating a consideration to proactively optimize IBD therapy plans. More prospective data are necessary to assess whether FC monitoring improves health outcomes.

Abstract
BACKGROUND AND AIM Non-invasive detection and monitoring of inflammatory bowel disease (IBD) is an important clinical challenge. Stool calprotectin is the most popular among available options, but the necessity of stool collection limits its acceptability. This study aimed to evaluate biomarker measurement in non-invasively collected colorectal mucus as a new tool for IBD detection and activity monitoring. METHODS Calprotectin, eosinophil-derived neurotoxin (EDN), and protein S100A12 were measured in colorectal mucus self-collected following defecation by 58 patients with IBD (before therapy), 50 patients with irritable bowel syndrome, and 33 healthy volunteers. Patients with IBD also collected samples at days 10, 20, and 30 of treatment for disease activity monitoring. RESULTS Protein biomarker levels were significantly (P < 0.001) higher in IBD patients than in irritable bowel syndrome and control groups. Calprotectin and EDN effectively detected IBD with a respective sensitivity and specificity of 0.76 and 0.92 for calprotectin and 0.83 and 0.94 for EDN. S100A12 was less sensitive. Calprotectin and EDN results were combined in a new test (CALEDN) that had a sensitivity of 0.91 and a specificity of 0.89. Repeated biomarker measurement during IBD treatment demonstrated a steady decline of calprotectin and EDN levels as well as CALEDN values in patients responding to applied therapy and lack of this pattern in non-responders. CONCLUSIONS Measuring calprotectin and EDN in non-invasively collected colorectal mucus presents a simple and efficient method for IBD detection and monitoring. Excellent performance of EDN for this purpose is reported for the first time. Combining calprotectin and EDN in one test improves IBD detection sensitivity.

Abstract
BACKGROUND Faecal calprotectin, an established biomarker used to assess mucosal inflammation, has been shown to correlate with endoscopic activity in inflammatory bowel disease (IBD). Longitudinal monitoring of faecal calprotectin, however, has rarely been employed beyond assessment of therapy response and post hoc analyses of clinical trials. AIM To study whether consecutive measurements of faecal calprotectin every third month are useful for monitoring patients with IBD in clinical remission. METHODS Patients aged 18 years or older, with a known diagnosis of IBD in clinical remission, were prospectively studied. Patients provided faecal samples every third month and were prospectively followed until the first clinical relapse or the end of the 2-year follow-up period. Measurements (EK-CAL, Bühlmann Lab. AG, Switzerland) were done at the end of the study. A Cox model with time-dependent covariates was used for analysis. RESULTS Among 104 patients, Crohn's disease (n = 49) and ulcerative colitis (n = 55), 37 had a relapse. A doubling of faecal calprotectin level between two consecutively collected samples was associated with a 101% increased risk of relapse (HR: 2.01; 95% CI: 1.53-2.65; P < 0.001). The relative risk of relapse attenuated with time (HR: 0.80; 95% CI: 0.75-0.86; P < 0.001), by a 20% decrease in risk of relapse per 3-month period since the sample was obtained. CONCLUSIONS By consecutively measuring faecal calprotectin every third month, we quantified the risk of relapse related to faecal calprotectin change and observed attenuation of the risk across time. Our data suggest that longitudinal monitoring of faecal calprotectin is informative in predicting relapse in IBD.

Abstract
BACKGROUND It is recommended that ileocolonoscopy is performed within 1 year after resection for Crohn's disease (CD). Nevertheless, optimal monitoring strategies for recurrence after the ileocolonoscopy remain to be elucidated. This prospective study was to evaluate the value of serial monitoring of faecal calprotectin (FC) after ileocolonoscopy for the assessment of endoscopic recurrence in asymptomatic patients. METHODS Patients in clinical remission who had no endoscopic recurrence at ileocolonoscopy 6-12 months after ileocolonic resection were studied. FC levels were measured every 2 months up to 24 months after the ileocolonoscopy. When the FC level was elevated (⩾140 µg/g), a second ileocolonoscopy was immediately undertaken. In contrast, patients who maintained low FC levels (<140 µg/g) during the 24-month follow up underwent a second ileocolonoscopy at the end of the study. Endoscopic recurrence was defined as a Rutgeerts score ⩾i2. RESULTS A total of 30 patients were studied. In eight patients, the FC level was raised during the 24-month follow up. Six of the eight patients (75%) had endoscopic recurrence. Of 22 patients who maintained low FC levels, 20 (91%) had no endoscopic recurrence, whereas two showed endoscopic recurrence at the end of the follow up. The incidence of endoscopic recurrence was significantly higher in patients with elevation of FC levels versus those with maintained low FC levels (75% versus 9%). A cut-off value of 140 µg/g for FC had a sensitivity of 75%, a specificity of 91%, a positive predictive value of 75%, a negative predictive value of 91% and a diagnostic accuracy of 87% to detect endoscopic recurrence. CONCLUSIONS Consecutive monitoring of FC is useful for the assessment of endoscopic recurrence after the initial ileocolonoscopy. Increased FC levels indicate a need for repeat ileocolonoscopy, while sustained low FC levels predict a low risk of endoscopic recurrence. In patients maintaining low FC levels, unnecessary invasive endoscopic examinations can be avoided.

Abstract
BACKGROUND The ST2/IL-33 pathway has been related to ulcerative colitis (UC), and soluble ST2 (sST2), to disease severity. We tested the potential usefulness of sST2 as a predictive marker of treatment response and patients' outcome. METHODS Twenty-six patients with active UC were prospectively recruited and grouped according to an endoscopic score and therapy response. Colonoscopic biopsies were collected at baseline and 6 months or when patients showed clinical activity. The protocol was reinitiated in patients requiring rescue therapy. Blood and stool were collected at baseline, 1, 3, 6 and 12 months. Serum and mucosal ST2, and fecal calprotectin (FC) content were determined by ELISA and correlated to Mayo clinical and endoscopic subscore. Intestinal ST2 was evaluated by immunofluorescence. Wilcoxon signed rank test and Spearman correlations (Rs) were applied (p <0.05). RESULTS Follow-up was completed in 24 patients. sST2 levels (median and range) varied from 173.5 [136.6-274.0] to 86.5 [54.6-133.2] in responders (p < 0.05), and 336.3 [211.0-403.2] to 385.3 pg/mL [283.4-517.3] in non-responders at baseline and 6 months, respectively. sST2 levels correlated with Mayo clinical and endoscopic subscore, mucosal ST2 and FC (Rs = 0.57, 0.66, 0.74 and 0.42, respectively; p < 0.0001) and showed a trend similar to that of FC in responders. Non-responders revealed an increased ST2 content, restricted to the lamina propria's cellular infiltrate. CONCLUSIONS Consecutive sST2 measurement to follow changes in inflammatory activity of UC patients who respond or not to treatment identifies sST2, like FC, as a useful biomarker in predicting clinical outcome of UC patients.

Abstract
BACKGROUND Faecal biomarkers are emerging tools in the assessment of mucosal healing in inflammatory bowel diseases (IBDs). AIM To evaluate the accuracy of faecal chitinase 3-like 1(CHI3L1) compared to calprotectin in detecting endoscopic activity in IBD. METHODS Overall, 86 IBD adults underwent colonoscopy consecutively and prospectively, with Crohn's disease Endoscopic Index of Severity (CDEIS) or Mayo endoscopic subscore calculation for ulcerative colitis, and stool collection. Faecal calprotectin was measured using quantitative immunochromatographic testing. Faecal CHI3L1 was quantified by ELISA. CHI3L1 cut-off value was determined using a receiver-operating curve. RESULTS In 54 Crohn's disease patients, faecal CHI3L1 (ρ = 0.70, P < 0.001) and calprotectin (ρ = 0.74, P < 0.001) levels correlated with CDEIS and were significantly increased in patients with endoscopic ulceration. In patients with ileal Crohn's disease, faecal CHI3L1 seemed to be better correlated with CDEIS than faecal calprotectin (ρ = 0.78 vs. ρ = 0.62, P < 0.001 for both). CHI3L1 > 15 ng/g detected endoscopic ulceration in Crohn's disease with a sensitivity of 100% and a specificity of 63.6%, compared to faecal calprotectin > 250 μg/g showing a sensitivity of 90.5% and a specificity of 59.1%. In 32 ulcerative colitis patients, faecal CHI3L1 and calprotectin levels correlated with Mayo endoscopic subscore (ρ = 0.44 and 0.61, respectively, P < 0.001 for both) and were significantly increased in ulcerative colitis patients with endoscopic activity. In ulcerative colitis patients, faecal CHI3L1 > 15 ng/g predicted endoscopic activity with a sensitivity of 81.8% and a specificity of 80.0%, compared to faecal calprotectin>250 μg/g showing a sensitivity of 86.4% and a specificity of 80.0%. CONCLUSION Faecal CHI3L1 is a reliable biomarker in detecting endoscopic activity in IBD.
