Outcomes reported in randomised trials of surgical prehabilitation: a scoping review. Br J Anaesth 2024; 133:42-57. [PMID: 38570300 DOI: 10.1016/j.bja.2024.01.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 01/09/2024] [Accepted: 01/29/2024] [Indexed: 04/05/2024] Open
Abstract
BACKGROUND Heterogeneity of reported outcomes can impact the certainty of evidence for prehabilitation. The objective of this scoping review was to systematically map outcomes and assessment tools used in trials of surgical prehabilitation. METHODS MEDLINE, EMBASE, PsychInfo, Web of Science, CINAHL, and Cochrane were searched in February 2023. Randomised controlled trials of unimodal or multimodal prehabilitation interventions (nutrition, exercise, psychological support) lasting at least 7 days in adults undergoing elective surgery were included. Reported outcomes were classified according to the International Society for Pharmacoeconomics and Outcomes Research framework. RESULTS We included 76 trials, mostly focused on abdominal or orthopaedic surgeries. A total of 50 different outcomes were identified, measured using 184 outcome assessment tools. Observer-reported outcomes were collected in 86% of trials (n=65), with hospital length of stay being most common. Performance outcomes were reported in 80% of trials (n=61), most commonly as exercise capacity assessed by cardiopulmonary exercise testing. Clinician-reported outcomes were included in 78% (n=59) of trials and most frequently included postoperative complications with Clavien-Dindo classification. Patient-reported outcomes were reported in 76% (n=58) of trials, with health-related quality of life using the 36- or 12-Item Short Form Survey being most prevalent. Biomarker outcomes were reported in 16% of trials (n=12) most commonly using inflammatory markers assessed with C-reactive protein. CONCLUSIONS There is substantial heterogeneity in the reporting of outcomes and assessment tools across surgical prehabilitation trials. Identification of meaningful outcomes, and agreement on appropriate assessment tools, could inform the development of a prehabilitation core outcomes set to harmonise outcome reporting and facilitate meta-analyses.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is a progressive immune-mediated liver disease, for which no medical therapy has been shown to slow disease progression. However, the horizon for new therapies is encouraging, with several innovative clinical trials in progress. Despite these advancements, there is considerable heterogeneity in the outcomes studied, with lack of consensus as to what outcomes to measure, when to measure and how to measure. Furthermore, there has been a paradigm shift in PSC treatment targets over recent years, moving from biochemistry-based endpoints to histological assessment of liver fibrosis, imaging-based biomarkers and patient-reported outcome measures. The abundance of new interventional trials and evolving endpoints pose opportunities for all stakeholders involved in evaluating novel therapies. To this effect, there is a need to harmonise measures used in clinical trials through the development of a core outcome set (COS). METHODS AND ANALYSIS Synthesis of a PSC-specific COS will be conducted in four stages. Initially, a systematic literature review will be performed to identify outcomes previously used in PSC trials, followed by semistructured qualitative interviews conducted with key stakeholders. The latter may include patients, clinicians, researchers, pharmaceutical industry representatives and healthcare payers and regulatory agencies, to identify additional outcomes of importance. Using the outcomes generated from the literature review and stakeholder interviews, an international two-round Delphi survey will be conducted to prioritise outcomes for inclusion in the COS. Finally, a consensus meeting will be convened to ratify the COS and disseminate findings for application in future PSC trials. ETHICS AND DISSEMINATION Ethical approval has been granted by the East Midlands-Leicester Central Research Ethics Committee (Ref: 24/EM/0126) for this study. The COS from this study will be widely disseminated including publication in peer-reviewed journals, international conferences, promotion through patient-support groups and made available on the Core Outcomes Measurement in Effectiveness Trials (COMET) database. TRIAL REGISTRATION NUMBER 1239.

Baseline Data and Measurement Instruments Reported in Observational Studies in Inflammatory Bowel Disease: Results from a Systematic Review. J Crohns Colitis 2024; 18:875-884. [PMID: 38214470 DOI: 10.1093/ecco-jcc/jjae004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 12/04/2023] [Accepted: 01/11/2024] [Indexed: 01/13/2024]
Abstract
BACKGROUND Heterogeneity in demographic and outcomes data with corresponding measurement instruments [MIs] creates barriers to data pooling and analysis. Several core outcome sets have been developed in inflammatory bowel disease [IBD] to homogenize outcomes data. A parallel Minimum Data Set [MDS] for baseline characteristics is lacking. We conducted a systematic review to develop the first MDS. METHODS A systematic review was made of observational studies from three databases [2000-2021]. Titles and abstracts were screened, full-text articles were reviewed, and data were extracted by two reviewers. Baseline data were grouped into ten domains: demographics, clinical features, disease behaviour/complications, biomarkers, endoscopy, histology, radiology, healthcare utilization and patient-reported data. Frequency of baseline data and MIs within respective domains are reported. RESULTS From 315 included studies [600 552 subjects], most originated from Europe [196; 62%] and North America [59; 19%], and were published between 2011 and 2021 [251; 80%]. The most frequent domains were demographics [311; 98.7%] and clinical [289; 91.7%]; 224 [71.1%] studies reported on the triad of sex [306; 97.1%], age [289; 91.7%], and disease phenotype [231; 73.3%]. Few included baseline data for radiology [19; 6%], healthcare utilization [19; 6%], and histology [17; 5.4%]. Ethnicity [19; 6%], race [17; 5.4%], and alcohol/drug consumption [6; 1.9%] were the least reported demographics. From 25 MIs for clinical disease activity, the Harvey-Bradshaw Index [n = 53] and Mayo score [n = 37] were most frequently used. CONCLUSIONS Substantial variability exists in baseline population data reporting. These findings will inform a future consensus for MDS in IBD to enhance data harmonization and credibility of real-world evidence.

Abstract
Although ulcerative colitis [UC] shares many common pathways and therapeutic options with Crohn's disease [CD], CD patients are four times more likely to undergo surgery 10 years into their disease in the biological era and are more likely to have extraintestinal manifestations than UC patients. Early treatment in CD has been demonstrated to modify the natural history of the disease and potentially delay surgery. Previous reviews on this topic have borrowed their evidence from CD to make UC-specific recommendations. This review highlights the emergence of UC-specific data from larger cohort studies and a comprehensive individual patient data systemic review and meta-analysis to critically appraise evidence on the utility of early escalation to advanced therapies with respect to short-, medium-, and long-term outcomes. In UC, the utility of the early escalation concept for the purposes of changing the natural history, including reducing colectomy and hospitalizations, is not supported by the available data. Data on targeting clinical, biochemical, endoscopic, and histological outcomes are needed to demonstrate that they are meaningful with regard to achieving reductions in hospitalization and surgery, improving quality of life, and minimizing disability. Analyses of different populations of UC patients, such as those with 'relapsing & remitting' disease or with severe or complicated disease course, are urgently needed. The costs and risk/benefit profile of some of the newer advanced therapies should be carefully considered. In this clinical landscape, it appears premature to advocate an indiscriminate 'one size fits all' approach to escalating to advanced therapies early during the course of UC.

Clinical importance of weight gain and associated factors in patients with moderate to severe ulcerative colitis: results from the MOSAIK cohort in Korea. BMC Gastroenterol 2023; 23:405. [PMID: 37990156 PMCID: PMC10664292 DOI: 10.1186/s12876-023-03008-7] [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: 10/19/2023] [Indexed: 11/23/2023] Open
Abstract
BACKGROUND Many patients with ulcerative colitis (UC) gain weight after treatment. However, the clinical significance of weight gain in these patients remains unclear. This study aimed to evaluate body weight changes after treatment in patients newly diagnosed with moderate-to-severe UC and their effects on patients' prognosis. METHODS The change in weight between diagnosis and 1 year after treatment in 212 patients enrolled in the MOSAIK cohort (mean age, 40 years; males, 60%) was analyzed. Significant weight gain was defined as a weight increase of ≥ 5% from the baseline at 1 year. Factors associated with significant weight gain and the effect of significant weight gain on the risk of major adverse outcomes (clinical relapse, hospitalization, and new use of steroids or biologics) during a follow-up period of 20 months were evaluated. RESULTS Mean weight gain at 1 year was 1.7 ± 4.2 kg. The proportion of overweight/obese patients increased by 9.0% from 37.9% to 46.9%. Thirty-two percent had significant weight gain; extensive colitis at diagnosis was the only factor associated with significant weight gain (odds ratio 6.5, 95% confidence interval 1.4-31.0, p = 0.006). In multivariable analysis, significant weight gain was not associated with the risk of major adverse outcomes. Weight loss symptoms at diagnosis were associated with an increased risk for new steroid use after 1 year. CONCLUSIONS Approximately one-third of patients with moderate-to-severe UC had significant weight gain after 1 year of treatment. However, significant weight gain was not associated with the patient's prognosis.

Abstract
BACKGROUND Only one head-to-head comparison of advanced treatments in moderately to severely active ulcerative colitis (UC) has been published; therefore, there remains a need for further comparisons. AIM The relative treatment effects of filgotinib and adalimumab, golimumab, infliximab, tofacitinib, ustekinumab and vedolizumab were estimated using a network meta-analysis (NMA). METHOD Systematically identified studies (MEDLINE, Embase and Cochrane Library; searched: inception-May 2019, updated November 2020) investigating treatments for moderately to severely active UC were re-evaluated for inclusion in a Bayesian NMA (fixed-effects model). Relative treatment effects were estimated using different permutations of patient population (biologic-naïve or biologic-experienced), treatment phase (induction or maintenance) and outcomes (MCS response/remission or endoscopic mucosal healing). RESULTS Seventeen trials (13 induction; 9 maintenance) were included in the NMA; 8 treatment networks were constructed. Most targeted therapies were superior to placebo in terms of MCS response/remission and endoscopic mucosal healing; filgotinib 200 mg was similar to most other treatments. Infliximab 5 mg/kg was superior to filgotinib 200 mg (biologic-naïve; induction) for MCS response/remission (mean relative effect, 0.34 [95% credible interval: 0.05, 0.62]). Filgotinib 200 mg was superior to adalimumab 160/80/40 mg for MCS response/remission (biologic-experienced; induction; - 0.75 [- 1.16, - 0.35]), and endoscopic mucosal healing (biologic-naïve; maintenance; - 0.90 [- 1.89, - 0.01]); and to golimumab 50 mg every 4 weeks (biologic-naïve; maintenance; - 0.46 [- 0.94, 0]) for MCS response/remission. CONCLUSION The current treatment landscape benefits patients with moderately to severely active UC, improving key outcomes; filgotinib 200 mg was similar to current standard of care in most outcomes.

Abstract
BACKGROUND The medical treatment of fistulizing Crohn's disease (CD) remains a challenge to clinicians. Over the last 20 years, biologic therapies have been the mainstay of medical treatment of fistulizing CD. The purpose of this study is to compare the efficacy of biologic therapies in inducing response and remission in fistulizing CD. METHODS We performed a systematic review of the EMBASE, MEDLINE, and Cochrane Central databases from inception to December 2021. Inclusion criteria were any randomized controlled trials (RCTs) that evaluated the efficacy of biologic therapies against an active comparator or placebo for induction of response or remission in adults with fistulizing CD. The proportion of patients with fistula response or remission, as defined by each clinical trial, was our primary study outcome. A Bayesian random-effects network meta-analysis was used to measure treatment effects and results were reported as odds ratio (OR) and 95% confidence interval (CI). RESULTS In our analysis, 10 studies were included, and all were RCTs. Infliximab was superior to adalimumab in inducing response (OR, 0.24; 95% CI, 0.06-0.99) but not in inducing remission (OR, 0.31; 95% CI, 0.04-2.27). Tumor necrosis factor antagonists were superior to placebo in the induction of response (OR, 0.51; 95% CI, 0.35-0.750) and remission (OR, 0.36; 95% CI, 0.22-0.58). Infliximab was superior to placebo in inducing response (OR, 0.36; 95% CI, 0.17-0.75) and remission (OR, 0.17; 95% CI, 0.03-0.87). Ustekinumab was superior to placebo in inducing response (OR, 0.48; 95% CI, 0.26-0.860) but not in inducing remission (OR, 0.50; 95% CI, 0.13-1.93). When comparing biologic therapies against each other, there was no statistical difference in inducing remission. Vedolizumab was not superior to placebo in inducing remission (OR, 0.32; 95% CI, 0.04-2.29). Certolizumab was not superior to placebo in inducing response (OR, 0.78; 95% CI, 0.40-1.55) or remission (OR, 0.78; 95% CI, 0.40-1.55). CONCLUSIONS Tumor necrosis factor antagonists are effective in inducing response and remission in fistulizing CD. Infliximab was superior to adalimumab for inducing response but not for inducing remission. Ustekinumab is effective in the induction of response but not in the induction of remission. When compared against each other, biologic therapies showed no significant difference in the induction of remission. Based on the available data, infliximab is the preferred first-line treatment. As for other biologics, the limited published data do not allow us to make firm recommendations. This study supports current practice and emphasizes the need for dedicated RCTs to evaluate the efficacy of biologic therapies in fistulizing CD.

Abstract
OBJECTIVES Comparative trials among biological drugs for the treatment of ulcerative colitis (UC) provided conflicting results. After patent expire of infliximab originator, adalimumab, infliximab biosimilar, golimumab and vedolizumab have been approved in Italy.We compared the efficacy of these four biologics in UC according to the concept of continuous clinical remission (CCR). METHODS In a retrospective, multicentre study, all UC patients treated with adalimumab, infliximab biosimilar, golimumab or vedolizumab between 2014 and 2019 were included. All drugs were compared to each other according to the 1-year CCR rate, defined as Mayo partial score ≤2, with bleeding subscore = 0, without any relapse or optimization with dose escalation, topical treatments or steroid use after first clinical remission. RESULTS Four-hundred sixteen patients (adalimumab = 90, infliximab biosimilar = 105, golimumab = 79, vedolizumab = 142) were included. CCR was achieved in similar percentages among the groups (33%, 37%, 28%, 37%, respectively). All drugs were equivalent in biologic-naive patients, while vedolizumab was better than a second anti-TNFα in prior anti-TNFα agent failures. No differences were found according to type of adverse events or severe adverse events. CONCLUSIONS Based on a strict definition of clinical remission, all biologics appear equally effective at 1 year. Changing to vedolizumab is more effective than switching to another anti-TNFα in TNFα failures.

A Narrative Systematic Review and Categorisation of Outcomes in Inflammatory Bowel Disease to Inform a Core Outcome Set for Real-world Evidence. J Crohns Colitis 2022; 16:1511-1522.

Abstract
BACKGROUND Heterogeneity exists in reported outcomes and outcome measurement instruments [OMI] from observational studies. A core outcome set [COS] for observational and real-world evidence [RWE] in inflammatory bowel disease [IBD] will facilitate pooling large datasets. This systematic review describes and classifies clinical and patient-reported outcomes, for COS development. METHODS The systematic review of MEDLINE, EMBASE, and CINAHL databases identified observational studies published between 2000 and 2021 using the population exposure outcome [PEO] framework. Studies meeting eligibility criteria were included. After titles and abstracts screening, full-text articles were extracted by two independent reviewers. Primary and secondary outcomes with corresponding OMI were extracted and categorised in accordance with OMERACT Filter 2.1 framework. The frequency of outcomes and OMIs are described. RESULTS From 5854 studies, 315 were included: 129 [41%] Crohn's disease [CD], 60 [19%] ulcerative colitis [UC], and 126 [40%] inflammatory bowel disease [IBD] studies with 600 552 participants. Totals of 1632 outcomes and 1929 OMI were extracted mainly from medical therapy [181; 72%], surgical [34; 11%], and endoscopic [6; 2%] studies. Clinical and medical therapy-related safety were frequent outcome domains recorded in 194 and 100 studies. Medical therapy-related adverse events [n = 74] and need for surgery [n = 71] were the commonest outcomes. The most frequently reported OMI were patient or event numbers [n = 914], Harvey-Bradshaw Index [n = 45], and Montreal classification [n = 42]. CONCLUSIONS There is substantial variability in outcomes reporting and OMI types. Categorised outcomes and OMI from this review will inform a Delphi consensus on a COS for future RWE in IBD. Data collection standardisation may enhance the quality of RWE applied to decision-making.

Abstract
BACKGROUND & AIMS End points to determine the efficacy and safety of medical therapies for Crohn's disease (CD) and ulcerative colitis (UC) are evolving. Given the heterogeneity in current outcome measures, harmonizing end points in a core outcome set for randomized controlled trials is a priority for drug development in inflammatory bowel disease. METHODS Candidate outcome domains and outcome measures were generated from systematic literature reviews and patient engagement surveys and interviews. An iterative Delphi process was conducted to establish consensus: panelists anonymously voted on items using a 9-point Likert scale, and feedback was incorporated between rounds to refine statements. Consensus meetings were held to ratify the outcome domains and core outcome measures. Stakeholders were recruited internationally, and included gastroenterologists, colorectal surgeons, methodologists, and clinical trialists. RESULTS A total of 235 patients and 53 experts participated. Patient-reported outcomes, quality of life, endoscopy, biomarkers, and safety were considered core domains; histopathology was an additional domain for UC. In CD, there was consensus to use the 2-item patient-reported outcome (ie, abdominal pain and stool frequency), Crohn's Disease Activity Index, Simple Endoscopic Score for Crohn's Disease, C-reactive protein, fecal calprotectin, and co-primary end points of symptomatic remission and endoscopic response. In UC, there was consensus to use the 9-point Mayo Clinic Score, fecal urgency, Robarts Histopathology Index or Geboes Score, fecal calprotectin, and a composite primary end point including both symptomatic and endoscopic remission. Safety outcomes should be reported using the Medical Dictionary for Regulatory Activities. CONCLUSIONS This multidisciplinary collaboration involving patients and clinical experts has produced the first core outcome set that can be applied to randomized controlled trials of CD and UC.

Aliment Pharmacol Ther 2022; 55:1277-1296. [PMID: 35229332 DOI: 10.1111/apt.16846] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 11/03/2021] [Accepted: 02/13/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Coeliac disease (CeD) is an immune-mediated small bowel enteropathy resulting from dietary gluten exposure. Presently, the only effective treatment is adoption of a gluten-free diet (GFD), although strict adherence is challenging to maintain, and inadvertent gluten exposures are inevitable for most patients. Hence, there is substantial interest in drug development in CeD and multiple novel therapies are under investigation. AIMS To review existing and upcoming clinical trial programmes for pharmacologic agents for CeD. METHODS A narrative review was performed, informed by a search of MEDLINE, Embase, the Cochrane CENTRAL Library and clinicaltrials.gov. RESULTS We summarise the pathophysiology of CeD and the specific steps that are potentially amenable to pharmacologic treatment. We evaluate the evidence supporting existing and future drug targets, including trials of peptidases, gluten sequestrants, tight junction regulators, anti-transglutaminase 2 therapies, immune tolerizing agents, advanced biologics and small molecules, and microbiome-targeted strategies. We highlight unique considerations for conducting CeD trials, including identifying appropriate study populations, assessing results in the context of a gluten challenge, and interpreting CeD-specific clinical and histologic outcomes. Understanding these factors is crucial for accurately appraising the evidence. Finally, we outline what the future of CeD therapy may hold with the introduction of pharmacotherapies. CONCLUSIONS There is a need for pharmacologic options for CeD, either used adjunctively with a GFD for accidental or intentional gluten exposures or for refractory disease. Multiple promising agents are in development, and these trials are likely to lead to approvals for the first generation of pharmacologic agents for CeD within the next 5 years.

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.

Abstract
OBJECTIVES Knowledge of the extent of variation in outcome assessment for inflammatory bowel disease (IBD) in routine practice is limited. We aimed to describe and quantify variation in outcome coverage and to explore patient, clinician and practitioner factors associated with it. DESIGN Prospective exploratory mixed-methods study. SETTING IBD clinics at six hospitals in North West England with differing electronic health record (EHR) systems. METHODS Mixed-methods study comprising: (a) structured observations of outcomes elicited during consultations (102 patients consulting 24 clinicians); (b) retrospective analysis of outcomes recorded in the EHR (909 consultations; 127 clinicians) and (c) semistructured interviews with the 24 observed clinicians. We determined whether specific outcome 'sets' were elicited or recorded, including: (1) a minimum set of symptom pairs ('PRO-2'); (2) symptom sets from disease activity indices and (3) a reference list of 37 symptoms, signs and impacts. Factors associated with variation were explored in univariate and multivariate binary logistic regression analyses and from clinician interviews. RESULTS PRO-2 coverage was not invariable (elicited during 81% of observed consultations; recorded in 56% of EHR) and infrequent for complete activity indices (all domains from Harvey-Bradshaw Index: elicited, 18%; recorded, 5%). The median number of outcomes from the reference list elicited per consultation was 12 (13-fold variation) and recorded in EHR was 7 (>20-fold variation). Symptom quantification (PRO-2) seldom adhered closely to standardised descriptors and an explicit timeframe was defined rarely. PRO-2 recording in EHR was associated with a diagnosis of ulcerative colitis (OR: 2.09 (95% CI 1.15 to 3.80)) and nurse-led consultations (OR: 6.98 (95% CI 3.28 to 14.83)) and a three-way model suggested 26% of total variability lay between clinicians, 17% between patients but the remainder was unexplained. Most clinicians expressed preference for individualised health status evaluations versus standardised outcome assessments. CONCLUSIONS There was little evidence for standardised assessment and recording of IBD outcomes and substantial intra-clinician and inter-clinician variation from one consultation to another. Nurses demonstrated a greater tendency to standardised practice.

Composite outcomes in observational studies of ulcerative colitis: A systematic review and meta-analysis. United European Gastroenterol J 2021; 10:54-72. [PMID: 34907660 PMCID: PMC8830283 DOI: 10.1002/ueg2.12183] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Accepted: 11/18/2021] [Indexed: 12/13/2022] Open
Abstract
Background Ulcerative colitis (UC) has been the focus of numerous observational studies over the years and a common strategy employed in their design is the use of composite and aggregate outcomes. Objective This systematic review and meta‐analysis aims to identify composite and aggregate outcomes of observational studies in UC and to evaluate how the number and type of variables included and the length of follow‐up affect the frequency of patients that achieve these outcomes. Methods A systematic literature search was carried out using MEDLINE [via PubMed], Scopus, and Web of Science online databases. Observational studies that included UC patients and reported composite or aggregate outcomes were identified. A set of variables considered to be representative of progressive or disabling UC was defined, the proportion of patients attaining the outcomes was determined and a random‐effects meta‐analysis was performed by dividing the identified studies into subgroups according to different criteria of interest. Results A total of 10,264 records were identified in the systematic search, of which 33 were retained for qualitative analysis and 20 were included in the meta‐analysis. The mean frequency for composite outcomes was 0.363 [95% confidence interval (CI) 0.323‐0.403]. The frequency of composite outcome for the subgroup of studies that included the variable “Biologics” was significantly higher than for those in which this variable was not reported [0.410; 95% CI 0.364‐0.457 versus 0.298; 95% CI 0.232‐0.364; p = 0.006]. Composite outcomes were also more frequent as the follow‐up duration increased. Conclusion The frequency of composite outcomes in observational studies of UC is dependent on the specific identity of the variables being reported. Moreover, longer follow‐up periods are associated with higher frequencies of composite outcomes. The evidence provided here is useful for the design of future observational studies of UC that aim to maximize the frequency of patients that achieve composite outcomes. Summarize the established knowledge on this subject Observational studies have become a valuable source of information but also present a remarkable heterogeneity. The inconsistency on the reported outcomes between individual studies and the potential for reporting biases has led to calls for the development of core outcome sets (COS).
What are the significant and/or new findings of this study? This is the first systematic review and meta‐analysis of outcomes in observational studies of Ulcerative colitis (UC). The frequency of composite outcomes in observational studies of UC is dependent on the specific identity of the variables being reported and on the follow‐up duration. Reporting of the variable “Biologics” significantly increased the frequency of composite outcomes. These findings may be useful for the design of future observational studies of UC.

Early course of newly diagnosed moderate-to-severe ulcerative colitis in Korea: Results from a hospital-based inception cohort study (MOSAIK). J Gastroenterol Hepatol 2021; 36:2149-2156. [PMID: 33555067 DOI: 10.1111/jgh.15435] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 01/12/2021] [Accepted: 02/03/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND AND AIM No inception cohort study has ever evaluated the early course of moderate-to-severe ulcerative colitis (UC) within 1 year of diagnosis in the non-Caucasian population. We aimed to investigate the early clinical course of moderate-to-severe UC patients in terms of remission, relapse, UC-related hospitalizations, colectomy, mortality, and overall use of medications. METHODS In the MOSAIK inception cohort, which is an ongoing multicenter, prospective, hospital-based, observational cohort, 354 patients with moderate-to-severe UC were followed up for 1 year. Main outcomes of UC and predictive factors for medication use over the course of 1 year were evaluated. RESULT Among 354 patients, 276 (78.0%) patients were followed up for 1 year. The rates of remission, relapse, UC-related hospitalizations, and proximal disease extension were 95.3%, 39.6%, 15.2%, and 12.3%, respectively. Systemic corticosteroids, thiopurines, and biologics were administered to 61.2%, 30.4%, and 10.5% of patients, respectively, throughout 1 year. One year after, 58.2% patients experienced remission or mild endoscopic activity. Overall disease courses did not show much difference according to moderate or severe disease activity at baseline. In addition, no colectomy and mortality were observed for 1 year. Predictive factors for medication use included disease severity, disease extent, endoscopic severity, and presence of periappendiceal inflammation at baseline for corticosteroid, disease extent and initial corticosteroid use for thiopurine, and only initial corticosteroid use for biologics. CONCLUSION Korean patients with moderate-to-severe UC may have more favorable early outcomes than Western patients. However, outcomes of them need to be further looked into for a longer time.

Abstract
BACKGROUND & AIMS Histopathology is an emerging treatment target in ulcerative colitis (UC) clinical trials. Our aim was to provide guidance on standardizing biopsy collection protocols, identifying optimal evaluative indices, and defining thresholds for histologic response and remission after treatment. METHODS An international, interdisciplinary expert panel of 19 gastroenterologists and gastrointestinal pathologists was assembled. A modified RAND/University of California, Los Angeles appropriateness methodology was used to address relevant issues. A total of 138 statements were derived from a systematic review of the literature and expert opinion. Each statement was anonymously rated as appropriate, uncertain, or inappropriate using a 9-point scale. Survey results were reviewed and discussed before a second round of voting. RESULTS Histologic measurements collected using a uniform biopsy strategy are important for assessing disease activity and determining therapeutic efficacy in UC clinical trials. Multiple biopsy strategies were deemed acceptable, including segmental biopsies collected according to the endoscopic appearance. Biopsies should be scored for architectural change, lamina propria chronic inflammation, basal plasmacytosis, lamina propria and epithelial neutrophils, epithelial damage, and erosions/ulcerations. The Geboes score, Robarts Histopathology Index, and Nancy Index were considered appropriate for assessing histologic activity; use of the modified Riley score and Harpaz Index were uncertain. Histologic activity at baseline should be required for enrollment, recognizing this carries operational implications. Achievement of histologic improvement or remission was considered an appropriate and realistic therapeutic target. Current histologic indices require validation for pediatric populations. CONCLUSIONS These recommendations provide a framework for standardized implementation of histopathology in UC trials. Additional work is required to address operational considerations and areas of uncertainty.

Abstract
BACKGROUND Significant associations between serum golimumab concentrations and favourable outcomes have been observed during both induction and maintenance therapy in ulcerative colitis (UC). However, data regarding optimal therapeutic serum golimumab concentration thresholds are limited. AIMS To identify optimal serum golimumab concentration thresholds during induction and maintenance treatment with golimumab. METHODS GO-LEVEL was an open label, phase IV study that included a prospective cohort of UC patients commencing golimumab, as well as a cross-sectional cohort receiving maintenance treatment. Patients commencing induction for active UC (defined as a simple clinical colitis activity index [SCCAI] >5 in addition to a raised faecal calprotectin [FC] >59μg/g or, raised C-reactive protein [CRP] [>5mg/L] or, Mayo endoscopic disease activity 2 or 3) were evaluated at weeks 6, 10 and 14. Patients receiving maintenance therapy were recruited either at the point of flare or during remission. Combined clinical-biochemical remission was defined as SCCAI ≤2 and FC <250μg/g. Serum golimumab concentrations were measured using a commercially available ELISA (LISATRACKER, Theradiag). RESULTS Thirty-nine patients were included in the induction cohort, of whom 15 (38%) achieved combined clinical-biochemical remission at week 6. The median serum golimumab concentration of those in combined clinical-biochemical remission was significantly higher than those who were not (5.0 vs 3.1 μg/mL, respectively, P = 0.03). Receiver operating characteristic (ROC) curve analysis demonstrated 3.8 μg/mL as the optimal threshold (sensitivity 0.71, specificity 0.65, area under curve [AUC] 0.72, positive predictive value [PPV] 0.59 and negative predictive value [NPV] 0.79). Sixty-three patients were included in the maintenance cohort; 31 (49%) were in combined remission, 32 (51%) were not. The median serum golimumab concentration of those in combined remission was significantly higher (2.9 vs 2.1 μg/mL, respectively, P = 0.01). ROC curve analysis demonstrated 2.4 μg/mL as the optimal threshold (sensitivity 0.68, specificity 0.66, AUC 0.68, PPV 0.65 and NPV 0.66). CONCLUSIONS GO-LEVEL (NCT03124121) offers further evidence regarding golimumab's exposure-response relationship. Clinicians may consider using therapeutic drug monitoring to optimise golimumab dosing aiming to achieve our suggested therapeutic thresholds of 3.8 μg/mL at week 6 and 2.4 μg/mL during maintenance.

Abstract
In the last few decades several new molecules have been developed in the field of inflammatory bowel diseases. However, the process that leads to the approval and use of a new drug is very long, expensive and complex, consisting of various phases. There is a pre-clinical phase that is performed on animals and a clinical phase that is directed to humans. Each research phase aims to evaluate different aspects of the drug and involves a specific target group of subjects. In addition, many aspects must be considered in the evaluation of a clinical trial: randomization, presence of a control group, blind design, type of data analysis performed, and patient stratification. The objective of this review is to provide an overview of the clinical trial phases of a new drug in order to better understand and interpret their results.

Abstract
Crohn's disease and ulcerative colitis are increasingly prevalent, relapsing and remitting inflammatory bowel diseases (IBDs) with variable disease courses and complications. Their aetiology remains unclear but current evidence shows an increasingly complex pathophysiology broadly centring on the genome, exposome, microbiome and immunome. Our increased understanding of disease pathogenesis is providing an ever-expanding arsenal of therapeutic options, but these can be expensive and patients can lose response or never respond to certain therapies. Therefore, there is now a growing need to personalise therapies on the basis of the underlying disease biology and a desire to shift our approach from "reactive" management driven by disease complications to "proactive" care with an aim to prevent disease sequelae. Precision medicine is the tailoring of medical treatment to the individual patient, encompassing a multitude of data-driven (and multi-omic) approaches to foster accurate clinical decision-making. In IBD, precision medicine would have significant benefits, enabling timely therapy that is both effective and appropriate for the individual. In this review, we summarise some of the key areas of progress towards precision medicine, including predicting disease susceptibility and its course, personalising therapies in IBD and monitoring response to therapy. We also highlight some of the challenges to be overcome in order to deliver this approach.

Abstract
The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of inflammatory bowel disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the general principles of surgical treatment of inflammatory bowel disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Abstract
Introduction: The management of patients with ulcerative colitis (UC) has evolved over the past few decades. While aminosalicylates remain the mainstay of induction and maintenance therapy in patients with mild-to-moderate UC, the advent of biologic agents and novel oral small molecules has substantively changed the treatment landscape for patients with moderate-to-severe disease and confounded the role of traditional immunomodulators (IMMs) such as thiopurines and methotrexate in the UC management algorithm.Areas covered: We summarize the mechanism of action of thiopurines and methotrexate, identify clinical parameters for their use, and appraise the evidence supporting the efficacy and safety of IMMs in UC as both monotherapy and in combination with other therapies, emphasizing on prospective, controlled data.Expert opinion: With the advent of several classes of highly effective treatments for UC, emergence of data demonstrating no benefit of IMMs over placebo, and concerns about the relative safety profile of long-term IMM exposure, we propose that the role of thiopurines or methotrexate be restricted to patients with milder disease failing to maintain corticosteroid-free remission on aminosalicylates alone or in combination therapy with tumor necrosis factor antagonists in patients with moderate-to-severe UC.

Abstract
AbstractBackgroundThere is widespread concern that treatment with biologic agents may be associated with suboptimal postoperative outcome after surgery for inflammatory bowel diseases (IBD).AimWe aimed to search and analyze the literature regarding the potential association of biologic treatment on adverse postoperative outcome in patients with IBD. We used the subject as a case in point for surgical research. The aim was not to conduct a new systematic review.MethodThis is an updated narrative review written in a collaborative method by authors invited through Twitter via the following hashtags (#OpenSourceResearch and #SoMe4Surgery). The manuscript was presented as slides on Twitter to allow discussion of each section of the paper sequentially. A Google document was created, which was shared across social media, and comments and edits were verified by the primary author to ensure accuracy and consistency.ResultsForty-one collaborators responded to the invitation, and a total of 106 studies were identified that investigated the potential association of preoperative biological treatment on postoperative outcome in patients with IBD. Most of these studies were retrospective observational cohorts: 3 were prospective, 4 experimental, and 3 population-based studies. These studies were previously analyzed in 10 systematic/narrative reviews and 14 meta-analyses. Type of biologic agents, dose, drug concentration, antidrug antibodies, interval between last dose, and types of surgery varied widely among the studies. Adjustment for confounders and bias control ranged from good to very poor. Only 10 studies reported postoperative outcome according to Clavien–Dindo classification.ConclusionAlthough a large number of studies investigated the potential effect of biological treatment on postoperative outcomes, many reported divergent results. There is a need for randomized controlled trials. Future studies should focus on the avoiding the weakness of prior studies we identified. Seeking collaborators and sharing information via Twitter was integral to widening the contributors/authors and peer review for this article and was an effective method of collaboration.

Clin Gastroenterol Hepatol 2019; 17:2050-2059.e1. [PMID: 30471455 DOI: 10.1016/j.cgh.2018.11.029] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Revised: 10/04/2018] [Accepted: 11/13/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Inflammatory bowel disease (IBD) scoring systems combine patient-reported data with physicians' observations to determine patient outcomes, but these systems are believed to have limitations. We used real-world data from a large IBD cohort in Switzerland to compare results between patients and healthcare professionals from scoring systems for Crohn's disease (CD) and ulcerative colitis (UC). METHODS We collected data from the Swiss IBD cohort, beginning in 2006, using 2453 reports for 1385 patients (52% female, 58% with CD). During office visits, physicians asked patients about signs and symptoms and recorded their answers (health care professional-reported outcomes). On a later date, patients received a questionnaire at home (independently of the medical visit), complete it, and sent it back to the data center. Patients also completed the short form 36 and IBD quality of life (QoL) questionnaires. We calculated Cohen's kappa (κ) statistics to assess the level of agreement in scores between patients and health care professionals (Δt between reports collected less than 2 months apart). We used Spearman correlation coefficients (ρ) to compare general well-being (GWB) and QoL scores determined by patients vs health care professionals. Our primary aim was to investigate the overall and individual level of agreement on signs and symptoms reported by health care professionals vs patients. RESULTS The best level of agreement (although moderate) was observed for number of stools last week in patients with CD (κ = 0.47), and nocturnal diarrhea in patients with UC (κ = 0.52). Agreement was low on level of abdominal pain (κ = 0.31 for patients with CD and κ = 0.37 for patients with UC) and GWB (κ = 0.23 for patients with CD and κ = 0.26 for patients with UC). Patients reported less severe abdominal pain and worse GWB (CD) or better GWB (UC) than that determined by health care professionals. Patient self-rated GWB correlated with IBD quality of life (ρ = 0.68 for patients with CD and ρ = 0.70 for patients with UC) and SF-36 physical scores (ρ = 0.55 for patients with CD and ρ = 0.60 for patients with UC); there was no correlation between health care professional-rated GWB and QoL. CONCLUSIONS In a comparison of patient vs health care provider-reported outcomes in a Swiss IBD cohort, we found that health care professionals seem to misinterpret patients' complaints. Patients self-rated GWB correlated with QoL scores, indicating that reporting GWB in a single question is possible and relevant, but can vary based on how the data are collected.

Abstract
BACKGROUND AND AIMS Nocebo effects, adverse outcomes occurring in patients receiving inert therapy, contribute to adverse event [AE] reporting in randomized controlled trials [RCTs]. High placebo AE rates may result in inaccurate estimation of treatment-related AEs. We estimate the pooled rate of AEs in patients randomized to placebo compared to active therapy in inflammatory bowel disease [IBD] RCTs. METHODS MEDLINE, EMBASE and CENTRAL were searched to March 1, 2017 for RCTs of conventional medical therapies for Crohn's disease [CD] or ulcerative colitis [UC]. Rates of AEs, serious AEs [SAEs], AE-related trial withdrawal, infections and worsening IBD were pooled using a random-effects model. RESULTS We included 124 CD [n = 26 042] and 71 UC RCTs [n = 16 798]. The pooled placebo AE rate was 70.6% (95% confidence interval [CI]: 65.3%, 75.4%) and 54.5% [47.8%, 61.1%] in CD and UC RCTs, respectively. There was no significant risk difference [RD] in AE, SAE or AE-related withdrawal rates between CD patients receiving placebo or active drug. A 1.6% [95% CI: 0.1%, 3.1%] increase in AE rates was observed among UC patients randomized to active therapy. Patients receiving active therapy had a higher risk of infection (RD 1.0% [95% CI: 0.4%, 1.7%] for CD, 2.9% [95% CI: 1.4%, 4.4%] for UC) although a lower risk of worsening CD (RD -3.2% [95% CI: -4.8%, -1.5%]) or UC (RD -3.7% [95% CI: -5.7%, -1.8%]). CONCLUSIONS AEs are commonly reported by patients randomized to either placebo or active treatment in IBD RCTs. Clinically relevant differences in AE, SAE and AE-related withdrawal were not observed.

Abstract
Background Cortiment®MMX® (budesonide MMX®) is currently approved for the induction of remission in mild-to-moderate ulcerative colitis (UC) patients when 5-ASA treatment is not sufficient. Data in real-life settings are lacking. Methods This was a multicentre observational prospective cohort study conducted in Europe and Canada. Effectiveness, safety, and tolerability of Cortiment®MMX® in a real-life setting of patients treated for mild-to-moderate UC was investigated. Patients were prescribed Cortiment®MMX® in accordance with the Summary of the Product Characteristics (SmPC).The primary endpoint was the clinical benefit of Cortiment® MMX® in routine practice (improvement ≥ 3 points in the clinical sub-scores of the Ulcerative Colitis Disease Activity Index, UCDAI). Results Data from 326 patients with mild-to-moderate UC were analysed for the primary endpoint. Clinical benefit was achieved in 60.1% (196/326) of patients at the end of Cortiment®MMX® treatment. Clinical remission (UCDAI clinical sub-score ≤ 1), full symptoms resolution (rectal bleeding (RB) = 0 and stool frequency (SF) = 0) and symptoms resolution (RB = 0 + SF ≤ 1) at the end of the Cortiment®MMX® treatment were achieved in 51.8%, 45.1% and 63.2% of patients, respectively. The median time to symptoms resolution was 30 days (range 29.0-36.0 days). Fifty patients (14.3%) had to discontinue Cortiment®MMX® due to adverse events; 17.5% of patients (n = 61) reported at least one adverse event related to the study drug. Conclusions This was the first time that a large cohort study was conducted with Cortiment®MMX® in a real-life setting. It demonstrated that Cortiment®MMX® is effective, safe and well tolerated in about 60% of UC patients.

Abstract
BACKGROUND Janus kinase (JAK) inhibitors represent a novel therapeutic class for treatment of inflammatory bowel disease. AIMS To determine the efficacy and safety of JAK inhibitors compared to placebo for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). METHODS PubMed, Embase and CENTRAL were systematically searched to November 1, 2018. Randomised placebo-controlled trials (RCTs) of JAK inhibitors in adult patients with CD or UC were eligible. Open-label extension studies without a placebo comparator arm were excluded. Clinical, endoscopic, and safety outcomes were extracted and rates relative to placebo were pooled using a random-effects model. RESULTS A total of 12 RCTs (5 CD, 7 UC) were included. Patients were randomised to placebo (n = 844), tofacitinib (n = 1882), filgotinib (n = 130), peficitinib (n = 176), upadacitinib (n = 387) or TD-1473 (n = 31). JAK inhibitor treatment was associated with induction of clinical remission in CD (RR, relative risk 1.38 [95% confidence interval CI 1.04-1.83], P = 0.025, I2 = 14%) and UC (RR 3.07 [95% CI 2.03-4.63], P < 0.001, I2 = 0%). In UC, JAK inhibitor treatment was associated with induction of endoscopic remission (endoscopic Mayo subscore MCSe = 0/1) (RR 2.43 [95% CI 1.64-3.59], P < 0.001, I2 = 27%) and mucosal healing (MCSe = 0) (RR 5.50 [95% CI 2.46-12.32], P < 0.001, I2 = 0%). JAK inhibitor treatment increased the risk of infection compared to placebo (RR 1.40 [95% CI 1.18-1.67], P < 0.001, I2 = 0%), particularly for herpes zoster. CONCLUSIONS JAK inhibitors are effective for inducing clinical remission in CD and induction of clinical and endoscopic remission in UC, although are associated with an increased risk of infectious complications.

Abstract
Treatment targets in both randomized controlled trials (RCTs) and daily practice have evolved for patients with ulcerative colitis (UC), motivated by changing regulatory requirements and efforts to alter the disease's natural history. Substantial heterogeneity in outcome definitions has been identified in UC RCTs.1 To harmonize treatment outcomes that should be reported, we proposed the collaborative development of a core outcome set (COS).2 A COS is an agreed minimum set of outcomes that should be measured and reported in all clinical trials to facilitate reporting consistency, reduce selective reporting bias, and improve quality of evidence synthesis.3.

Histologic Healing Rates of Medical Therapies for Ulcerative Colitis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Am J Gastroenterol 2019; 114:733-745.

Abstract
OBJECTIVES Histologic remission is a potentially valuable means of assessing disease activity and treatment response in ulcerative colitis (UC). However, the efficacy of existing therapies to achieve this outcome is unclear. We performed a systematic review and meta-analysis of histologic outcomes in UC randomized controlled trials and examined the relationship between histologic and endoscopic outcomes. METHODS MEDLINE, EMBASE, CENTRAL, and the Cochrane IBD Register were searched for randomized controlled trials of aminosalicylates, corticosteroids, immunosuppressives, biologics, and small molecules. Histologic and endoscopic remission and response data were independently extracted and pooled using binomial-normal random-effect or fixed-effect models. Pooled efficacy estimates were calculated as risk ratios (RRs) using the Mantel-Haenszel method. Univariable and multivariable random-effect meta-regression models examined factors associated with histologic remission. RESULTS Seventy-four studies (68 induction and 7 maintenance) were identified. Topical aminosalicylate enemas [37.2%, 95% confidence interval (CI), 29.0-46.3] and suppositories (44.9%, 95% CI, 28.9-62.3) had the highest induction of histologic remission rates. Aminosalicylate enemas (RR = 4.14, 95% CI, 2.35-7.31), aminosalicylate suppositories (RR = 3.94, 95% CI, 1.26-12.32), and budesonide multimatrix (RR = 1.47, 95% CI 1.08-1.99) had higher histologic remission rates than placebo. Data were lacking for biologics and immunosuppressives. The pooled histologic remission rate for placebo in induction studies was 10.4% (95% CI, 7.1-15.2). Histologic and endoscopic remission correlated strongly (r = 0.66; 95% CI, 0.50-0.78). In multivariate analysis of placebo-arm data, less severe clinical disease activity and corticosteroid use were associated with higher histologic remission rates. Similarly, mild clinical disease activity was associated with higher histologic remission rates when active-arm data were analyzed. CONCLUSIONS Histologic remission rates for current UC treatments ranged from 15.0% to 44.9% according to drug class and patient population with the highest rates observed for topical aminosalicylates. Placebo remission rates were low with relatively narrow CIs. These data provide benchmarks to inform future trial design. Histologic remission is a potential treatment target in clinical practice.

Abstract
BACKGROUND The suitability of disease activity indices has been challenged, with growing interest in objective measures of inflammation. AIM To undertake a systematic review of efficacy and safety outcomes in placebo-controlled randomised controlled trials (RCTs) of patients with Crohn's disease. METHODS MEDLINE, EMBASE, CINAHL and Cochrane Library were searched until November 2015, for RCTs of adult Crohn's disease patients treated with medical or surgical therapies. Data on efficacy and safety outcomes, end-point definitions, and measurement instruments were extracted and stratified by publication date (pre-2009 and 2009 onwards). RESULTS One hundred and eighty-one RCTs (110 induction and 71 maintenance) were identified, including 23 850 patients. About 92.3% reported clinical efficacy endpoints. The Crohn's Disease Activity Index (CDAI) dominated, defining clinical response or remission in 63.5% of trials (35 definitions of response or remission). CDAI < 150 was the commonest endpoint, but reporting reduced between periods (46.4%-41.1%), whilst use of CDAI100 increased (16.8%-30.4%). Fistula studies most commonly reported fistula closure (9, 90.0%). Reporting of biomarker, endoscopy and histology endpoints increased overall (33.3%-40.6%, 14.4%-30.4% and 3.2%-12.5%, respectively), but were heterogeneous and rarely reported in fistula trials. Patient-reported outcome measures were reported in 41.4% of trials and safety endpoints in 35.4%. Many of the common adverse events relate to disease exacerbation or treatment failure. CONCLUSIONS Trial endpoints vary across studies, over time and are distinct in fistula studies. Despite growth in reporting of objective measures of inflammation and in patient-reported outcome measures, there is a lack of standardisation. This confirms the need for a core outcome set for comparative effectiveness research in Crohn's disease.

Systematic review with meta-analysis: high prevalence and cost of continued aminosalicylate use in patients with ulcerative colitis escalated to immunosuppressive and biological therapies. Aliment Pharmacol Ther 2019; 49:364-374. [PMID: 30569460 DOI: 10.1111/apt.15090] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 10/01/2018] [Accepted: 11/19/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND Aminosalicylates are the most frequently prescribed treatment for ulcerative colitis (UC). In the absence of empirical evidence, clinicians are uncertain whether to continue aminosalicylates in patients with UC after escalating therapy. AIMS To quantify concomitant aminosalicylate use in UC randomised clinical trials (RCTs), identify factors associated with their use, and estimate treatment costs of concomitant aminosalicylate therapy. METHODS MEDLINE, Embase, and CENTRAL were searched from inception to 1 March 2017 for placebo-controlled RCTs of immunosuppressants, biologics, or oral small molecules in adults with UC. The proportion of patients prescribed concomitant aminosalicylates at trial entry was pooled using a random-effects model. Meta-regression was performed to assess trial-level factors associated with aminosalicylate use. Treatment costs were estimated using 2018 formulary data from five Canadian provinces. RESULTS Thirty-two trials were included (23 induction only, nine induction, and maintenance trials). The pooled proportion of patients co-prescribed aminosalicylates was 80.7% (95% CI 75.5%-85.1%), with considerable observed heterogeneity (I2 = 95%). In univariable meta-regression, aminosalicylate use was not associated with trial design, setting, year of publication, disease severity, disease duration, or drug class. The estimated direct annual treatment cost of concomitant aminosalicylates is ~$20 million for the Canadian UC population, assuming conservative estimates of UC prevalence, aminosalicylate use and dose, and the lowest cost formulation. CONCLUSIONS Approximately 80% of UC patients entering clinical trials of immunosuppressants, biologics, or oral small molecules continue to use aminosalicylates. An RCT is needed to inform the benefits and harms of continuing vs stopping aminosalicylates in patients escalating therapy.

Abstract
BACKGROUND & AIMS Fistulas are debilitating complications of Crohn's disease (CD) that affect up to 50% of patients. We conducted a systematic review and meta-analysis of randomized controlled trials to assess the efficacy of treatments for fistulizing CD. METHODS We searched publication databases from inception through December 13, 2016 for trials comparing the efficacy of a therapeutic agent (single or combination) with placebo or another active therapy in adult patients with any form of fistulizing CD. The Cochrane risk of bias tool was used to assess the methodological quality of trials; the overall quality of evidence was evaluated using GRADE. Primary outcomes included induction and maintenance of fistula response and remission. Pooled risk ratios (RRs) and 95% CIs were calculated for each outcome. RESULTS We analyzed data from 27 trials; most studies (21/27) focused on patients with perianal fistulizing CD. We found moderate-quality evidence to support the efficacy of tumor necrosis factor (TNF) antagonists (RR, 2.01; 95% CI, 1.36-2.97), particularly infliximab, ustekinumab (RR, 1.77; 95% CI, 0.93-3.37), and mesenchymal stem cell therapy (RR, 1.31; 95% CI, 0.98-1.73) for induction of fistula remission. We found low-quality evidence for the efficacy of vedolizumab and immunosuppressives. There was also low-quality evidence to support the efficacy of combination therapy with TNF antagonists and antibiotics vs a TNF antagonist alone. CONCLUSION In a systematic review and meta-analysis of 27 controlled trials, we found TNF antagonists to be effective for induction and maintenance of perianal fistula response and remission. There are few data on the effects on internal fistulae. Further studies are needed, particularly for ustekinumab, vedolizumab, and stem cell therapies, in patients with fistulizing CD.

Abstract
BACKGROUND AND AIMS Assessment of disease activity is essential for developing and determining appropriate therapy in patients with ulcerative colitis (UC). Validated clinical and endoscopic scoring systems have been established to accurately define disease activity. Clinical and endoscopic treatment targets have also been proposed, with gastroenterologists encouraged to optimize medical therapy to achieve these targets. Recently, histology has been recognized as an important prognostic factor and potential treatment target in patients with UC. METHODS This review summarizes the recent literature regarding histologic scoring indices in UC and offers practical guidance to gastroenterologists on how to interpret histologic data. RESULTS Substantial evidence indicates that histology accurately predicts clinical relapse, hospitalization, corticosteroid use, and development of dysplasia. Furthermore, compared with endoscopy, findings suggest that histology may be more predictive of these outcomes. Because microscopic disease activity can persist in the absence of clinical or endoscopic disease activity, histology may be the ideal marker of inflammation. Standardized definitions of histologic response and remission and a biopsy procurement protocol are needed to guide clinical decision making. It is recommended that overall assessment of disease severity be determined according to the worst affected biopsy fragment. Crypt architectural distortion, basal plasmacytosis, and neutrophilic activity should be reported. A 5-category classification system based on disease chronicity/activity and basal plasmacytosis is proposed. It is not yet necessary to report on the degree of mucosal eosinophilia or use a validated scoring system, although the latter may aid in determining therapeutic response. CONCLUSIONS Although rarely used to measure inflammation and guide therapy, histologic disease activity is predictive of important clinical outcomes in UC. Randomized controlled trials are needed to determine whether histology should function as a treatment target.

Abstract
BACKGROUND & AIMS Agents are being developed for treatment of eosinophilic esophagitis (EoE). However, it is not clear what outcome measures would best determine the efficacy and safety of these agents in clinical trials. We performed a systematic review of outcomes used in randomized placebo-controlled trials of EoE and we estimate the placebo response and rates of remission. METHODS We searched MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, and the EU Clinical Trials Register from inception through February 20, 2018 for randomized controlled trials of pharmacologic therapies for EoE. Efficacy outcome definitions, measurement tools, and the proportion of patients responding to placebo were collected and stratified by based on histologic, endoscopic, and patient-reported outcomes. RESULTS We analyzed data from 22 placebo-controlled trials, comprising 1112 patients with EoE. Ten additional active registered trials were identified. Most published trials evaluated topical corticosteroid therapy (13/22, 59.1%). Histologic outcomes measuring eosinophil density and patient-reported outcomes were reported in 21/22 published trials (95.5%). No consistently applied definitions of histologic or patient-reported response or remission were identified. Endoscopic outcomes were described in 60% (12/20) of published trials. The EoE Endoscopic Reference Score is the most commonly applied tool for describing changes in endoscopic appearance. The median histologic response to placebo was 3.7% (range, 0%-31.6%) and the median rate of remission in patients given placebo was 0.0% (range, 0%-11.0%). The median patient-reported response to placebo was 14.4% (range, 8.6%-77.8%) and rate of remission in patients given placebo was 26.2% (range, 13.2%-35.7%). CONCLUSIONS In a systematic review of the literature, we found that no standardized definitions of histologic, endoscopic, or patient-reported outcomes are used to determine whether pharmacologic agents produce a response or remission in patients with EoE. A core outcome set is needed to reduce heterogeneity in outcome reporting and facilitate trial interpretation and comparison of results from trials.

Abstract
BACKGROUND & AIMS Endpoints in randomized controlled trials (RCTs) of Crohn's disease (CD) are changing. We performed a systematic review of efficacy and safety outcomes reported in placebo-controlled RCTs of patients with CD. METHODS We searched the MEDLINE, EMBASE, and the Cochrane Library through March 1, 2017 for placebo-controlled RCTs of adult patients with CD treated with aminosalicylates, immunomodulators, corticosteroids, biologics, and oral small molecules. Efficacy and safety outcomes, definitions, and measurement tools were collected and stratified by decade of publication. RESULTS Our final analysis included 116 RCTs (81 induction, 44 maintenance, 7 postoperative prevention trials, comprising 27,263 patients). Clinical efficacy endpoints were reported in all trials; the most common endpoint was CD activity index score. We identified 38 unique definitions of clinical response or remission and 32 definitions of loss of response. Definitions of endoscopic response, remission, and endoscopic healing were also heterogeneous, evaluated using the CD endoscopic index of severity, the simple endoscopic score for CD, ulcer resolution, and Rutgeerts' Score for postoperative endoscopic appearance. Histologic outcomes were reported in 11.1% of induction trials, 2.3% of maintenance trials, and 14.3% of postoperative prevention trials. Biomarker outcomes were reported in 81.5% induction trials, 68.2% of maintenance trials, and 42.9% of postoperative prevention trials. Safety outcomes were reported in 93.8% of induction trials, 97.7% of maintenance trials, and 85.7% of postoperative prevention trials. CONCLUSIONS In this systematic review, we demonstrate heterogeneity in definitions of response and remission, and changes in outcomes reported in RCTs of CD. It is a priority to select a core set of outcomes to standardize efficacy and safety evaluation in trials of patients with CD.

Abstract
PURPOSE OF REVIEW Since the first clinical trial of cortisone in ulcerative colitis in 1955, remarkable progress has been made in the design and conduct of clinical trials in inflammatory bowel diseases (IBD). In this review article, we will discuss evolution of clinical trials in IBD over the last 3-5 years. RECENT FINDINGS Recognizing limitations intrinsic to clinical disease activity indices in IBD, regulatory authorities have recommended evaluating co-primary endpoints of patient-reported outcomes and endoscopic disease activity in clinical trials. Biomarker-enriched trial enrolment and central endoscopy reading have emerged as critical events in trial recruitment and outcome assessment and have driven placebo response rates down. While trials of novel biologic therapies and advanced small molecules continue at an accelerated pace, pragmatic comparative efficacy trials of treatment strategy aimed at optimizing current therapies (such as early combined immunosuppression [REACT], tight disease control [CALM], therapeutic drug monitoring [TAXIT, TAILORIX]) have directly informed clinical practice. With emphasis on value-based care and population health management, multi-pronged remote monitoring, self-management, and telemedicine approaches in the era of smartphones have re-emerged with promise. Non-conventional therapies such as fecal microbiota transplantation, though still experimental, have provided insight into disease pathogenesis and offered hope for microbial manipulation strategies for treating these complex diseases. Clinical trials have rapidly evolved over the last 5 years not only focusing on novel therapies but also optimizing existing treatment approaches and population health management. Over the next decade, these trials will continue to advance the field, and be readily translatable into clinical practice.
