Systematic Literature Review: Ability of the IBDQ-32 to Detect Meaningful Change in Ulcerative Colitis Health Indicators

Purpose: Previous reviews produced weak evidence regarding the responsiveness of the Inflammatory Bowel Disease Questionnaire (IBDQ-32) to changes in ulcerative colitis (UC) health indicators. This systematic review and meta-analysis provide an updated synthesis on IBDQ-32 responsiveness. Methods: A systematic literature review identified 11 articles reporting IBDQ-32 responder analyses in randomized control trials, which were included in a random effects meta-analysis, and 15 articles linking IBDQ-32 change to change in UC health indicators, which were summarized narratively. Meta-analysis compared differences between IBDQ-32 responder proportions in efficacious and nonefficacious treatment arms relative to placebo. Linear meta-regression examined the association of treatment efficacy and proportions of IBDQ-32 responders in active treatment compared with placebo. Results: Meta-analysis showed larger differences in IBDQ-32 response proportions between active treatment and placebo for efficacious treatments (pooled OR, 2.19; 95% CI, 1.83-2.63) than nonefficacious treatments (pooled OR, 1.21; 95% CI, 0.84-1.74; Cochran's Q[df = 1] = 8.26, P = .004). Meta-regression showed that the magnitude of treatment efficacy positively predicted IBDQ-32 response in active treatments relative to placebo (β = 0.21, P < .001). Moderate to strong correlations were found between change in IBDQ-32 and change in health indicators (eg, patient-reported measures, disease activity, endoscopic indices; correlations, 0.37-0.64 in absolute values). Patients achieving clinical response or remission showed greater change in IBDQ-32 total scores (range, 22.3-50.1 points) and more frequently met clinically meaningful thresholds on the IBDQ-32 than those not achieving clinical response or remission (all P < .05). Conclusions: The IBDQ-32 is responsive to changes in UC health indicators and disease activity, including in response to efficacious treatment (relative to placebo)

Health-Related Quality of Life Outcomes With Tofacitinib Treatment in Patients With Ulcerative Colitis in the Open-Label Extension Study, OCTAVE Open

BACKGROUND Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. We report health-related quality of life (HRQoL) outcomes in patients with ulcerative colitis in the phase 3 open-label, long-term extension study, OCTAVE Open. METHODS The Inflammatory Bowel Disease Questionnaire (IBDQ), EuroQoL-5 Dimensions Health Questionnaire, and 36-Item Short Form Survey scores were analyzed up to month (M) 72 in 4 subpopulations: patients in remission at baseline (maintenance remitters) assigned tofacitinib 5 mg twice daily and patients not in remission at baseline (maintenance nonremitters, maintenance treatment failures, and induction nonresponders [IndNRs]) assigned tofacitinib 10 mg twice daily in OCTAVE Open. Data were analyzed overall and stratified by corticosteroid use at baseline, prior tumor necrosis factor inhibitor failure, and prior immunosuppressant failure. RESULTS Among maintenance remitters and nonremitters, HRQoL outcomes were maintained up to M72: 80.0% and 100.0% of patients had an IBDQ total score ≥170, respectively. At baseline, 7.4% of maintenance treatment failures had an IBDQ total score ≥170, and this increased to 54.3% and 75.0% at M2 and M72, respectively. Corresponding values for IndNRs were 22.6%, 51.0%, and 86.0%. HRQoL outcomes were independent of treatment history. Among patients not in remission at baseline, improvement in EuroQoL-5 Dimensions Health Questionnaire and 36-Item Short Form Survey scores was maintained or achieved by M2, and steady to M72 or M33, with maintenance treatment failures and IndNR subpopulations undergoing the biggest improvements from baseline. CONCLUSIONS A continued favorable impact on HRQoL was revealed with long-term tofacitinib treatment in OCTAVE Open, regardless of baseline remission status or treatment history.

Patient interpretations of patient-reported outcome measures to assess bowel urgency: qualitative interviews in ulcerative colitis

Objectives: Bowel urgency is an impactful core symptom of ulcerative colitis (UC). Patient-reported outcome (PRO) questionnaires have been developed and used to assess the patient experience of this important symptom. The objective of this paper is to present evidence from qualitative research conducted to support the use and interpretation of select PRO questionnaires to assess bowel urgency related to the UC patient experience. Methods: Qualitative interviews were conducted with ten adults with a clinician-confirmed diagnosis of moderately to severely active UC. Interviews aimed to document patient interpretation of modified recall periods for the Urgency Numeric Rating Scale (Urgency NRS), two global assessments (i.e., the Patient Global Impression of Severity [PGIS] and Patient Global Impression of Change [PGIC]), and four items (Items 11, 16, 23, and 26) of the Inflammatory Bowel Disease Questionnaire (IBDQ), and explore the patient perspective of meaningful change on these questionnaires. Results: Both modified Urgency NRS versions (with 7-day or 3-day recall period) were interpreted as intended by most patients (≥ 88.9%), and slightly more than half of patients (60.0%) reported that the 7-day recall period was more relevant to their bowel urgency experience. Patients reported thinking of bowel urgency (≥ 80.0%) or bowel urgency-related accidents (70.0% of patients) when interpreting the global assessments and IBDQ items. Most patients reported a 1- to 3-point change as the smallest meaningful improvement that would be meaningful on the Urgency NRS (similar to findings on other questionnaires). Conclusion: Adults with UC can understand and respond to the Urgency NRS with modified recall periods (i.e., 7-day or 3-day), interpret the conceptual content of the PGIS, PGIC, and select IBDQ items to be inclusive of bowel urgency and bowel urgency-related accidents, and select answers representing meaningful improvements on the Urgency NRS, PGIS, PGIC, and IBDQ item response scales. These results further contribute patient-centered data to existing UC and bowel urgency research

Iron Deficiency Is Common after Restorative Proctocolectomy with Ileal Pouch-Anal Anastomosis in Patients with Ulcerative Colitis

Background: Micronutrient deficiencies may occur after restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC), largely due to malabsorption and/or pouch inflammation. Objectives: The objective of this study was to report the frequency of iron deficiency in patients with UC who underwent RPC with IPAA and identify associated risk factors. Methods: We conducted a retrospective chart review of patients with UC or IBD-unclassified who underwent RPC with IPAA at Mount Sinai Hospital between 2008 and 2017. Patients younger than 18 years of age at the time of colectomy were excluded. Descriptive statistics were used to analyze baseline characteristics. Medians with interquartile range (IQR) were reported for continuous variables, and proportions were reported for categorical variables. Iron deficiency was defined by ferritin &lt;30 ng/mL. Logistic regression was used to analyze unadjusted relationships between hypothesized risk factors and the outcome of iron deficiency. Results: A total of 143 patients had iron studies a median of 3.0 (IQR 1.7–5.6) years after final surgical stage, of whom 73 (51.0%) were men. The median age was 33.5 (IQR 22.7–44.3) years. Iron deficiency was diagnosed in 80 (55.9%) patients with a median hemoglobin of 12.4 g/dL (IQR 10.9–13.3), ferritin of 14 ng/mL (IQR 9.0–23.3), and iron value of 44 μg/dL (IQR 26.0–68.8). Of these, 29 (36.3%) had a pouchoscopy performed within 3 months of iron deficiency diagnosis. Pouchitis and cuffitis were separately noted in 4 (13.8%) and 13 (44.8%) patients, respectively, and concomitant pouchitis-cuffitis was noted in 9 (31.0%) patients. Age, sex, anastomosis type, pouch duration, and history of pouchitis and/or cuffitis were not associated with iron deficiency. Conclusion: Iron deficiency is common after RPC with IPAA in patients with UC. Cuffitis is seen in the majority of patients with iron deficiency; however, iron deficiency may occur even in the absence of inflammation

Defining Transabdominal Intestinal Ultrasound Treatment Response and Remission in Inflammatory Bowel Disease: Systematic Review and Expert Consensus Statement

Background and Aims No consensus exists on defining intestinal ultrasound response, transmural healing, or transmural remission in inflammatory bowel disease, nor clear guidance for optimal timing of assessment during treatment. This systematic review and expert consensus study aimed to define such recommendations, along with key parameters included in response reporting. Methods Electronic databases were searched from inception to July 26, 2021, using pre-defined terms. Studies were eligible if at least two intestinal ultrasound [IUS] assessments at different time points during treatment were reported, along with an appropriate reference standard. The QUADAS-2 tool was used to examine study-level risk of bias. An international panel of experts [n = 18] rated an initial 196 statements [RAND/UCLA process, scale 1–9]. Two videoconferences were conducted, resulting in additional ratings of 149 and 13 statements, respectively. Results Out of 5826 records, 31 full-text articles, 16 abstracts, and one research letter were included; 83% [40/48] of included studies showed a low concern of applicability, and 96% [46/48] had a high risk of bias. A consensus was reached on 41 statements, with clear definitions of IUS treatment response, transmural healing, transmural remission, timing of assessment, and general considerations when using intestinal ultrasound in inflammatory bowel disease. Conclusions Response criteria and time points of response assessment varied between studies, complicating direct comparison of parameter changes and their relation to treatment outcomes. To ensure a unified approach in routine care and clinical trials, we provide recommendations and definitions for key parameters for intestinal ultrasound response, to incorporate into future prospective studies.publishedVersio

Predicting Outcomes in Pediatric Crohn’s Disease for Management Optimization: Systematic Review and Consensus Statements from PIBD-Ahead Program

A better understanding of prognostic factors within the heterogeneous spectrum of pediatric Crohn's disease (CD) should improve patient management and reduce complications. We aimed to identify evidence-based predictors of outcomes with the goal of optimizing individual patient management. A survey of 202 experts in pediatric CD identified and prioritized adverse outcomes to be avoided. A systematic review of the literature with meta-analysis, when possible, was performed to identify clinical studies that investigated predictors of these outcomes. Multiple national and international face-to-face meetings were held to draft consensus statements based on the published evidence. Consensus was reached on 27 statements regarding prognostic factors for surgery, complications, chronically active pediatric CD, and hospitalization. Prognostic factors for surgery included CD diagnosis during adolescence, growth impairment, NOD2/CARD15 polymorphisms, disease behavior, and positive anti-Saccharomyces cerevisiae antibody status. Isolated colonic disease was associated with fewer surgeries. Older age at presentation, small bowel disease, serology (anti-Saccharomyces cerevisiae antibody, antiflagellin, and OmpC), NOD2/CARD15 polymorphisms, perianal disease, and ethnicity were risk factors for penetrating (B3) and/or stenotic disease (B2). Male sex, young age at onset, small bowel disease, more active disease, and diagnostic delay may be associated with growth impairment. Malnutrition and higher disease activity were associated with reduced bone density. These evidence-based consensus statements offer insight into predictors of poor outcomes in pediatric CD and are valuable when developing treatment algorithms and planning future studies. Targeted longitudinal studies are needed to further characterize prognostic factors in pediatric CD and to evaluate the impact of treatment algorithms tailored to individual patient risk

An International Consensus to Standardize Integration of Histopathology in Ulcerative Colitis Clinical Trials

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

Impact of SARS-CoV-2 Vaccination on Inflammatory Bowel Disease Activity and Development of Vaccine-Related Adverse Events: Results From PREVENT-COVID

Severe acute respiratory syndrome coronavirus 2 vaccination is recommended for all individuals with inflammatory bowel disease (IBD), including those on immunosuppressive therapies; however, little is known about vaccine safety and efficacy in these patients or the impact of vaccination on IBD disease course.We evaluated coronavirus disease 2019 (COVID-19) vaccine–related adverse events (AEs) and the effect of vaccination on IBD disease course among participants in the PREVENT-COVID (Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID) study, a prospective, observational cohort study. Localized and systemic reactions were assessed via questionnaire. Disease flare was defined by worsening IBD symptoms and change in IBD medications. Outcomes were stratified by vaccine type and IBD medication classes.A total of 3316 individuals with IBD received at least 1 COVID-19 vaccine. Injection site tenderness (68%) and fatigue (46% dose 1, 68% dose 2) were the most commonly reported localized and systemic AEs after vaccination. Severe localized and systemic vaccine-related AEs were rare. The mRNA-1273 vaccine was associated with significantly greater severe AEs at dose 2 (localized 4% vs 2%, systemic 15% vs 10%; P &lt; .001 for both). Prior COVID-19 infection, female sex, and vaccine type were associated with severe systemic reactions to dose 1, while age &lt;50 years, female sex, vaccine type, and antitumor necrosis factor and vedolizumab use were associated with severe systemic reactions to dose 2. Overall rates (2%) of IBD flare were low following vaccination.Our findings provide reassurance that the severe acute respiratory syndrome coronavirus 2 vaccine is safe and well tolerated among individuals with IBD, which may help to combat vaccine hesitancy and increase vaccine confidence.The severe acute respiratory syndrome coronavirus 2 vaccine is safe and well tolerated among individuals with inflammatory bowel disease (IBD). Severe localized and systemic vaccine-related adverse events were rare, and rates of IBD flare were low (2%) following severe acute respiratory syndrome coronavirus 2 vaccination in a cohort of 3316 participants with IBD

Low Rates of Breakthrough COVID-19 Infection After SARS-CoV-2 Vaccination in Patients With Inflammatory Bowel Disease

We demonstrate low rates of breakthrough coronavirus disease 2019 (COVID-19) infection and mild course of illness following severe acute respiratory syndrome coronavirus 2 vaccination in a large cohort of inflammatory bowel disease patients. Residence in southern United States and lower median anti-receptor binding antibody level were associated with development of COVID-19
