Differences Between the 2016 and 2022 Food and Drug Administration Guidance-Implications for Design and Interpretation of Clinical Trials in Ulcerative Colitis. CROHN'S & COLITIS 360 2024; 6:otae038.

Abstract
Background In 2022, the Food and Drug Administration (FDA) updated its draft guidance for drug development in ulcerative colitis, replacing the version from 2016. Several changes from the 2016 version merit further discussion as they impact clinical trial design and the interpretation of trial results. Methods We compared both documents and critically appraised the changes and implications for future clinical trials. Results The 2022 guidance recommends full colonoscopy, rather than flexible sigmoidoscopy, to document disease activity in all involved segments of the colon. The concordance between the findings of the 2 procedures is very high and there is little evidence to support colonoscopy over sigmoidoscopy. The use of colonoscopy, rather than sigmoidoscopy, is also associated with a higher burden to trial participants who must undergo full bowel preparation, cost, and a potential for more adverse events. The definition of the Mayo endoscopic score of 0 was changed from the original publication to "normal appearance of mucosa," which suggests that endoscopic signs of prior disease, such as pseudopolyps and scarring, are incompatible with a score 0, even though they are not associated with active disease. The term "mucosal healing" has been abolished and histologic outcomes defined as exploratory. A welcome change is that shorter washout periods than 5 half-lives will be considered to reduce patient exposure to corticosteroids as bridging therapy. Conclusions The 2022 FDA draft guidance includes changes which for the most part are not informed by empirical evidence, which may ultimately complicate interpretation of future trials and preclude comparisons with past trials.

Abstract
INTRODUCTION Symptoms, endoscopy and histology have been proposed as therapeutic targets in ulcerative colitis (UC). Observational studies suggest that the achievement of histologic remission may be associated with a lower risk of complications, compared with the achievement of endoscopic remission alone. The actiVE ulcerative colitis, a RanDomIsed Controlled Trial (VERDICT) aims to determine the optimal treatment target in patients with UC. METHODS AND ANALYSIS In this multicentre, prospective randomised study, 660 patients with moderate to severe UC (Mayo rectal bleeding subscore [RBS] ≥1; Mayo endoscopic score [MES] ≥2) are randomly assigned to three treatment targets: corticosteroid-free symptomatic remission (Mayo RBS=0) (group 1); corticosteroid-free endoscopic remission (MES ≤1) and symptomatic remission (group 2); or corticosteroid-free histologic remission (Geboes score <2B.0), endoscopic remission and symptomatic remission (group 3). Treatment is escalated using vedolizumab according to a treatment algorithm that is dependent on the patient's baseline UC therapy until the target is achieved at weeks 16, 32 or 48. The primary outcome, the time from target achievement to a UC-related complication, will be compared between groups 1 and 3 using a Cox proportional hazards model. ETHICS AND DISSEMINATION The study was approved by ethics committees at the country level or at individual sites as per individual country requirements. A full list of ethics committees is available on request. Study results will be disseminated in peer-reviewed journals and at scientific meetings. TRIAL REGISTRATION NUMBER EudraCT: 2019-002485-12; NCT04259138.

Preoperative Use of Multiple Advanced Therapies Is Not Associated With Endoscopic Inflammatory Pouch Diseases. Inflamm Bowel Dis 2024; 30:203-212. [PMID: 37061838 DOI: 10.1093/ibd/izad054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Indexed: 04/17/2023]
Abstract
BACKGROUND Patients with an ileal pouch-anal anastomosis (IPAA) can experience pouch inflammation postoperatively. The use of antitumor necrosis factor (anti-TNF) biologics may be associated with pouch inflammation, but limited data exist on the impact of multiple advanced therapies on development of subsequent pouch inflammation. The aim of this study was to assess for an association between preoperative use of multiple advanced therapies and risk of endoscopically detected inflammatory pouch diseases (EIPDs). METHODS We performed a retrospective analysis of ulcerative colitis (UC) and indeterminate colitis (IBDU) patients who underwent an IPAA at a quaternary care center from January 2015 to December 2019. Patients were grouped based on number and type of preoperative drug exposures. The primary outcome was EIPD within 5 years of IPAA. RESULTS Two hundred ninety-eight patients were included in this analysis. Most of these patients had UC (95.0%) and demonstrated pancolonic disease distribution (86.1%). The majority of patients were male (57.4%) and underwent surgery for medically refractory disease (79.2%). The overall median age at surgery was 38.6 years. Preoperatively, 68 patients were biologic/small molecule-naïve, 125 received anti-TNF agents only, and 105 received non-anti-TNF agents only or multiple classes. Ninety-one patients developed EIPD. There was no significant association between type (P = .38) or number (P = .58) of exposures and EIPD, but older individuals had a lower risk of EIPD (P = .001; hazard ratio, 0.972; 95% confidence interval, 0.956-0.989). CONCLUSION Development of EIPD was not associated with number or type of preoperative advanced therapies.

Abstract
The landscape of ulcerative colitis has changed in the last two decades. Advancements in pharmacotherapeutics have heralded the introduction of new treatment options, with many agents in development. Better clinical outcomes are seen with tighter disease control, made possible with greater understanding of inflammatory pathways and their blockade with drugs. There has been a resultant shift in treatment targets, beyond symptoms to endoscopic and histological healing. Controlling the burden of disease activity also lowers the risk of developing colorectal cancer. Colorectal cancer screening now requires the use of dye-based agents and high-definition colonoscopy to improve the detection of colonic neoplasms.

Blood-Based Biomarkers Reflecting Protease 3 and MMP-12 Catalyzed Elastin Degradation as Potential Noninvasive Surrogate Markers of Endoscopic and Clinical Disease in Inflammatory Bowel Disease. J Clin Med 2023; 13:21. [PMID: 38202027 PMCID: PMC10779348 DOI: 10.3390/jcm13010021] [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: 11/14/2023] [Revised: 12/14/2023] [Accepted: 12/15/2023] [Indexed: 01/12/2024] Open
Abstract
Chronic inflammation in inflammatory bowel disease (IBD) triggers significant extracellular matrix remodeling, including elastin remodeling, leading to severe clinical complications. Novel methods to assess intestinal tissue destruction may act as surrogate markers of endoscopic disease activity, relieving patients of invasive endoscopy. We explored the noninvasive blood-based biomarkers ELP-3 and ELM-12, measuring elastin degradation in IBD. In a study involving 104 Crohn's disease (CD), 39 ulcerative colitis (UC), and 29 healthy donors, we assessed these biomarkers' association with endoscopic and clinical disease activity using ELISA. Patients were evaluated based on the SES-CD and CDAI for CD patients and modified MES and partial Mayo for UC patients. ELP-3 and ELM-12 were elevated in patients with IBD. Discerning CD patients in endoscopic remission and mild from moderate to severe, ELP-3 provided an AUC of 0.69 and ELM-12 an AUC of 0.73. The ELP-3 biomarker was associated with UC patients and provided the highest diagnostic power of 0.87 for remission vs. active clinical disease. The data suggest an association of ELP-3 with active CD and ELM-12 with endoscopic remission in CD patients. Additionally, ELP-3 could identify UC patients with active clinical disease from patients in remission. The noninvasive biomarkers ELP-3 and ELM-12 could be potential surrogate biomarkers of elastin degradation and endoscopic and clinical disease markers.

Pooled Phase 2 and 3 Efficacy and Safety Data on Budesonide Oral Suspension in Adolescents with Eosinophilic Esophagitis. J Pediatr Gastroenterol Nutr 2023; 77:760-768. [PMID: 37718471 PMCID: PMC10642696 DOI: 10.1097/mpg.0000000000003948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 08/07/2023] [Indexed: 09/19/2023]
Abstract
OBJECTIVES The objective of this study was to evaluate the efficacy and safety of budesonide oral suspension (BOS) in adolescents with eosinophilic esophagitis (EoE). METHODS This post hoc analysis pooled data from two 12-week, randomized, double-blind, placebo-controlled studies of BOS 2.0 mg twice daily (b.i.d.) (phase 2, NCT01642212; phase 3, NCT02605837) in patients aged 11-17 years with EoE and dysphagia. Efficacy endpoints included histologic (≤6, ≤1, and <15 eosinophils per high-power field [eos/hpf]), dysphagia symptom (≥30% reduction in Dysphagia Symptom Questionnaire [DSQ] scores from baseline), and clinicopathologic (≤6 eos/hpf and ≥30% reduction in DSQ scores from baseline) responses at week 12. Change from baseline to week 12 in peak eosinophil counts, DSQ scores, EoE Histology Scoring System (EoEHSS) grade (severity) and stage (extent) total score ratios (TSRs), and total EoE Endoscopic Reference Scores (EREFS) were assessed. Safety outcomes were also examined. RESULTS Overall, 76 adolescents were included (BOS, n = 45; placebo, n = 31). Significantly more patients who received BOS than placebo achieved histologic responses (≤6 eos/hpf: 46.7% vs 6.5%; ≤1 eos/hpf: 42.2% vs 0.0%; <15 eos/hpf: 53.3% vs 9.7%; P < 0.001) and a clinicopathologic response (31.1% vs 3.2%; P = 0.003) at week 12. More BOS-treated than placebo-treated patients achieved a dysphagia symptom response at week 12 (68.9% vs 58.1%; not statistically significant P = 0.314). BOS-treated patients had significantly greater reductions in EoEHSS grade and stage TSRs ( P < 0.001) and total EREFS ( P = 0.021) from baseline to week 12 than placebo-treated patients. BOS was well tolerated, with no clinically meaningful differences in adverse events versus placebo. CONCLUSIONS BOS 2.0 mg b.i.d. significantly improved most efficacy outcomes in adolescents with EoE versus placebo.

Alharthi F. Chicoric acid enhances the antioxidative defense system and protects against inflammation and apoptosis associated with the colitis model induced by dextran sulfate sodium in rats. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:119814-119824.

Abstract
Although several anticolitic drugs are available, their application is associated with numerous side effects. Chicoric acid (CA) is a hydroxycinnamic acid found naturally in chicory (Cichorium intybus), purple coneflower (Echinacea purpurea), and basil with numerous health benefits, such as antioxidative and anti-inflammatory activities. Here, the potential anticolitic efficiency of CA against dextran sulfate sodium (DSS)-induced colitis in rats was examined in rats. Animals were randomly assigned to the following five groups: control, CA (100 mg/kg body weight), DSS [(DSS); 4% w/v], CA + DSS (100 mg/kg), and the 5-aminosalicylic acid (100 mg/kg) + DSS group. The obtained data revealed that CA significantly prevented the shortening of colon length. Meanwhile, the oxidative stress-related enzymes were increased, while malondialdehyde and nitric oxide, were markedly decreased significantly by CA. The results also indicated that CA administration decreased significantly the pro-apoptogenic indices (Bax and caspase-3) and enhanced significantly Bcl-2, the anti-apoptogenic protein. Moreover, DSS caused a significant elevation of pro-inflammatory mediators, including interleukin-1β, tumor necrosis factor-α, myeloperoxidase, cyclooxygenase II, prostaglandin E2, and peroxisome proliferator-activated receptor gamma. Interestingly, these changes were significantly decreased following the CA administration. At the molecular level, CA supplementation has increased significantly the expression level of nuclear factor erythroid 2-related factor-2 (Nrf2) and decreased the expressions of nitric oxide synthase and mitogen-activated protein kinase 14. CA has been determined to significantly lessen DSS-induced colitis by activating Nrf2 and its derived antioxidant molecules and suppressing inflammation and apoptosis cascades associated with the development of colitis; suggesting that CA could be used as an alternative naturally-derived anticolitic agent.

Abstract
The latest guideline about ulcerative colitis (UC) clinical practice stresses that mucosal healing, rather than anti-inflammation, is the main target in UC clinical management. Current mucosal dysfunction mainly closely relates to the endoscopic intestinal wall (mechanical barrier) injury with the imbalance between intestinal epithelial cells (IECs) regeneration and death, as well as tight junction (TJ) dysfunction. It is suggested that biological barrier (gut microbiota), chemical barrier (mucus protein layer, MUC) and immune barrier (immune cells) all take part in the imbalance, leading to mechanical barrier injury. Lots of experimental studies reported that acupuncture and moxibustion on UC recovery by adjusting the gut microbiota, MUC and immune cells on multiple targets and pathways, which contributes to the balance of IEC regeneration and death, as well as TJ structure recovery in animals. Moreover, the validity and superiority of acupuncture and moxibustion were also demonstrated in clinic. This study aims to review the achievements of acupuncture and moxibustion on mucosal healing and analyse the underlying mechanisms.

Abstract
BACKGROUND Although validated patient-reported outcome (PRO) measurements can categorize patients with inflammatory bowel disease (IBD) into clinical remission or active disease, patients may have different definitions of remission. The purpose of this study was to compare patient-defined remission to remission based on PRO measures and physician global assessment (PGA) and to understand the clinical and demographic factors associated with disagreements. METHODS We retrospectively analyzed 3257 de-identified surveys from 2004 IBD patients who consented to participate in the Crohn's and Colitis Foundation's IBD Qorus Learning Health System between September 2019 and February 2021. We used logistic regression models with generalized estimating equations to analyze the clinical and demographic factors (eg, age, disease duration, health confidence) associated with discordance between patient-defined remission (yes/no) and PRO-defined remission for ulcerative colitis (UC; PRO2: stool frequency, rectal bleeding) and Crohn's disease (CD; PRO-3: average number of liquid stools, abdominal pain, well-being). RESULTS Among patients with UC, overall concordance was 79% between patient self-report and PRO2-defined remission and 49% between patient self-report and PGA-defined remission. Among patients with CD, overall concordance was 69% between patient self-report and PRO3-defined remission and 54% between patient self-report and PGA-defined remission. Patients in PRO-defined remission were more likely to report active disease if they had IBD <5 years and low health confidence. Patients with PRO-defined active disease were more likely to report remission if they were not using prednisone and had high health confidence. CONCLUSION Discordance exists between how remission is defined by patients, PRO measures, and PGA.

Abstract
Ulcerative colitis (UC) management has changed significantly in the past decade. The goal is to treat the symptoms, aid tissue healing, and change the disease course to improve future outcomes. Oral or topical mesalamine (5-ASA) is a well-known UC treatment. It is the standard for starting and maintaining recovery in mild-to-moderate illnesses. The majority of patients start the treatment in the first year after diagnosis and continue it for long periods. In this review article, PubMed/Medline, Google Scholar, and the Cochrane Library were used to search medical databases for relevant medical literature. After the articles were gathered and evaluated, 10 publications were compiled and selected using the qualifying criteria. The included articles aimed to provide an overview of 5-ASA in UC patients. According to several studies, there was no statistical relevance between various 5-ASA doses or the number of times they were taken. One study showed that 5-ASA cream preparation is better than oral preparation for patients with proctitis and proctosigmoiditis. The majority of the studies performed a follow-up to assess remission based on the use of endoscopy, fecal calprotectin, and patient symptoms during the investigations. Based on the aforementioned information, further investigation is required to ascertain the optimal approach for managing UC, with the aim of incorporating it into routine clinical procedures and enhancing our understanding of the subject matter.

Correlations Between Gastrointestinal Symptoms and Endoscopic-Histologic Disease Activity in Adults with Ulcerative Colitis. Dig Dis Sci 2023; 68:3254-3258. [PMID: 37268795 PMCID: PMC10936549 DOI: 10.1007/s10620-023-07986-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 05/22/2023] [Indexed: 06/04/2023]
Abstract
INTRODUCTION Discordance between gastrointestinal (GI) symptoms and endoscopic inflammation in patients with ulcerative colitis (UC) is known. However, the correlations between symptoms and endoscopic and histologic (endo-histologic) mucosal healing and remains unknown. METHODS We performed a secondary analysis of prospectively collected clinical, endoscopic, and histologic data on 254 colonoscopies from 179 unique adults at a tertiary referral center from 2014 to 2021. Spearman's rank was used to assess the correlation between patient reported outcomes and objective assessments of disease activity, as measured by validated instruments: Two-item patient-reported outcome measure (PRO-2) for stool frequency and rectal bleeding, the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) for endoscopic inflammation, and the Geboes score for histologic inflammation. The predictive value of objective assessments of inflammation and clinical symptoms was described using sensitivity, specificity, and positive/negative predictive value. RESULTS One-quarter (28%, 72/254) of cases were in endo-histologic remission; of these, 25% (18/72) report GI symptoms (22% diarrhea; 6% rectal bleeding). Endo-histologically active disease had higher sensitivity (95% rectal bleeding; 87% diarrhea) and negative predictive value (94% rectal bleeding, 78% diarrhea) for clinically active disease compared to active disease on endoscopic (77%) or histologic assessment only (80%). The specificity of endo/histologic inflammation for GI symptoms was < 65%. PRO-2 was positively correlated with endoscopic disease activity (Spearman's rank 0.57, 95% CI 0.54-0.60, p < 0.0001) and histologic disease activity (Spearman's rank 0.49, 0.45-0.53, p < 0.0001). CONCLUSION One-quarter of patients with ulcerative colitis in endo-histologic (deep) remission have gastrointestinal symptoms, more commonly with diarrhea than rectal bleeding. Endo-histologic inflammation has high sensitivity (≥ 87%) for diarrhea/rectal bleeding.

Abstract
BACKGROUND Patient-reported outcomes (PROs) are increasingly emphasized as endpoints in clinical trials of ulcerative colitis (UC). However, the prognostic value of early improvement in PROs for long-term outcomes remains unclear. METHODS This was a post-hoc analysis of 611 vedolizumab-treated or adalimumab-treated patients in the VARSITY trial (Clinicaltrial.gov: NCT02497469). Stool frequency (SF) and rectal bleeding score (RBS) as reported in the Mayo score at post-induction (week 6 and 14) was assessed for their association with one-year endoscopic improvement (EI), defined as Mayo endoscopic subscore <2; histo-endoscopic mucosal improvement (HEMI), defined as EI and Geboes highest grade <3.2, clinical remission (CR), defined as total Mayo score ≤2; and PRO-2 remission, defined as RBS of 0 and SF ≤1. Multivariable logistic regression models adjusted for confounders assessed the relationships between post-induction PROs and outcomes of interest at one-year. RESULTS Patients with severe SF at week 6 were significantly less likely to achieve one-year EI compared to those with non-severe SF [aOR 0.40 (95% CI: 0.24-0.68), p < .001]. Absence of rectal bleeding at week 6 was associated with greater odds of achieving EI at one-year [aOR 2.21 (95% CI: 1.58-3.09), p < .001]. These findings were consistent across comparisons at week 14. Similar findings were observed for the outcomes of one-year HEMI, CR and PRO-2 remission. No difference was observed between the modified partial Mayo score and modified PRO-2 score. CONCLUSIONS Post-induction PROs strongly predict the odds of CR and EI in UC and simplified evaluations can be used to assess early response to UC therapies.

Abstract
In patients with Crohn's disease and ulcerative colitis, poor correlation between symptoms and active luminal inflammation has been well established. As a result, the field has moved towards the use of endoscopic assessment to evaluate inflammatory activity. Numerous endoscopic indices have been used for this purpose although none are completely validated. The Simple Endoscopic Score for Crohn's Disease and the Crohn's Disease Endoscopic Index of Severity have been used most frequently; however in addition to incomplete validation, they have important limitations for clinical use, including complexity of scoring and poor reliability of items such as stenosis. The Rutgeerts' score for postoperative Crohn's disease was developed primarily as a prognostic rather than evaluative tool and also requires additional validation. In ulcerative colitis, the Mayo endoscopic subscore has been used as the regulatory standard, although the Ulcerative Colitis Endoscopic Index of Severity may provide a more granular assessment of individual components of disease activity. The use of combined outcomes with patient reported outcomes (PROs) and endoscopic indices has received favor by regulatory bodies but require further validation. This review describes the indications for endoscopic assessment in trials, the indices most frequently utilized for these purposes, and potential future approaches to assessment of disease activity.

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.

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. [PMID: 34943560 PMCID: PMC8700108 DOI: 10.3390/diagnostics11122323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 12/04/2021] [Accepted: 12/07/2021] [Indexed: 11/17/2022] Open
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.

Abstract
Twenty-five years ago the field was revolutionized by the introduction of infliximab as the first hybrid anti-TNF-antibody. Subsequently, other humanized anti-TNFs were developed and marketed, followed by antibodies to new targets including integrins (vedolizumab) and interleukin 12/23 (ustekinumab). All these so-called biologicals were shown in registrational trials to induce remission superior to placebo but consistently were effective in only a minority of patients. Even though in most trials only the responders were selected to continue on the respective medication for maintenance, many experienced a secondary loss of response and only a minority of usually <25% of the initial cohort achieved long-term (1 year) remission. In 'real life studies', the outcome was somewhat better, probably due to proper selection of patients and open, mostly retrospective study designs. A clear benefit of biologicals is apparent in otherwise treatment refractory patients, in extraintestinal manifestations and in Crohn´s disease (CD) with fistulizing complications. Biologicals achieve mucosal healing (MH) more often than corticosteroids or thiopurines, and MH is associated with improved prognosis. However, this does not justify escalating treatment until MH is reached since controlled trials proving this point of 'treat to target' are lacking both in ulcerative colitis and CD. Surgical rates have decreased with increasing use of biologicals, but disease progression has not been proven to improve. With the exception of opportunistic infections, serious adverse events are rare. In conclusion, biologicals have changed the scene considerably and expanded our armamentarium, but there is also a marketing hype fostering expectations without evidence.

Abstract
Introduction: Inflammatory bowel diseases (IBDs) are lifelong conditions causing relapsing inflammation of the intestine. In the absence of a cure, clinical management of IBDs is extremely challenging since they present with a wide range of phenotypes and disease behaviors. Hence, there is an urgent need for markers that could guide physicians in making the right choice of the rapidly growing treatment options toward a personalized care that could improve the overall outcome.Areas covered: In this review, the authors summarize existing biomarkers in IBD, discuss the challenges with the development of prognostic biomarkers and propose alternative options such as focusing on the prediction of the response to individual treatments, i.e. predictive biomarkers. The problems related to developing disease prognostic and predictive biomarkers in the field of IBDs are discussed including the difficulties in dealing with phenotypic heterogeneity particularly when performing studies in a real-life setting. The authors reviewed literature from PubMed.Expert opinion: Systems biology provides potential solutions to this problem by offering an unbiased, holistic approach to adjusting for variation in larger datasets thereby increasing the chances of identifying true associations between molecular profiles and clinical phenotypes.

Abstract
BACKGROUND AND AIM The aim was to assess non-invasive factors among clinical features, laboratory, and bowel ultrasound (BUS) characteristics and to develop a scoring system to predict endoscopic activities for ulcerative colitis (UC) patients. METHODS We performed a retrospective study collecting UC patients between January 2015 to September 2020. Logistic regression was performed to predict moderate-to-severe endoscopic activities, defined as endoscopic Mayo score ⩾2. Model performance was described with discrimination and calibration ability and validated by internal and external methods. RESULTS A total of 103 and 29 patients were enrolled in the modeling and validation groups, respectively. Stool frequency ⩾5 times/day, hematochezia, erythrocyte sedimentation rate (ESR), and colonic wall flow in BUS were included into two predictive models for endoscopic activities, both with good discrimination ability [Area under curve (AUC) 0.879 and 0.882, p < 0.001] and a sensitivity of 76.7% and specificity of 92.3%, which showed an adequate calibration ability by using the Hosmer-Lemeshow test (p = 0.14 and 0.07). The external validation displayed consistent results with the above mentioned. Nomograms were also established for these models. CONCLUSION We developed predictive models for endoscopic disease activities by using noninvasive factors based on stool frequency, hematochezia, ESR, and colonic wall blood flow in BUS. These models performed well in the internal and external validation.

[PMID: 34065300 PMCID: PMC8160866 DOI: 10.3390/biomedicines9050578] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 05/13/2021] [Accepted: 05/15/2021] [Indexed: 12/22/2022] Open
Abstract
5-Aminolevulinic acid (5-ALA) is a naturally occurring nonprotein amino acid licensed as an optical imaging agent for the treatment of gliomas. In recent years, 5-ALA has been shown to possess anti-inflammatory and immunoregulatory properties through upregulation of heme oxygenase-1 via enhancement of porphyrin, indicating that it may be beneficial for the treatment of inflammatory conditions. This study systematically examines 5-ALA for use in inflammatory bowel disease (IBD). Firstly, the ex vivo colonic stability and permeability of 5-ALA was assessed using human and mouse fluid and tissue. Secondly, the in vivo efficacy of 5-ALA, in the presence of sodium ferrous citrate, was investigated via the oral and intracolonic route in an acute DSS colitis mouse model of IBD. Results showed that 5-ALA was stable in mouse and human colon fluid, as well as in colon tissue. 5-ALA showed more tissue restricted pharmacokinetics when exposed to human colonic tissue. In vivo dosing demonstrated significantly improved colonic inflammation, increased local heme oxygenase-1 levels, and decreased concentrations of proinflammatory cytokines TNF-α, IL-6, and IL-1β in both plasma and colonic tissue. These effects were superior to that measured concurrently with established anti-inflammatory treatments, ciclosporin and 5-aminosalicylic acid (mesalazine). As such, 5-ALA represents a promising addition to the IBD armamentarium, with potential for targeted colonic delivery.

Abstract
Ulcerative colitis (UC) is a chronic disease that can present at various stages of disease activity and severity. Traditionally, severity scoring has focused on disease activity during a single moment with various tools, including patient-reported symptoms, as well as clinical, laboratory-based, endoscopic, histologic, and imaging variables. Optimal delivery of care depends on the accurate assessment of disease severity, which must take longitudinal variables into account. This article reviews the history of severity scoring in UC and provides a concise, clinically oriented approach to assessing disease severity.
