Abstract
PURPOSE To identify symptoms and their impacts on daily functioning and health-related quality of life (HRQoL) experienced by adult patients with ulcerative colitis (UC) and evaluate patient-reported outcome (PRO) measures for UC clinical studies. METHODS A conceptual model of symptoms and impacts of UC were developed from a literature review. PRO measures were identified from the literature, clinical trials databases, health technology assessment submissions, and regulatory label claims, and were selected for conceptual analysis based on disease specificity and use across information sources. PRO measures covering the most concepts when mapped against the conceptual model were assessed for gaps in psychometric properties using Food and Drug Administration (FDA) guidance and consensus-based standards for the selection of health measurement instruments (COSMIN) criteria. RESULTS The conceptual model grouped the 52 symptom concepts and 72 proximal and distal impacts into eight, two, and five dimensions, respectively. Of 65 PRO measures identified, eight underwent conceptual analysis. Measures covering the most concepts and assessed for psychometric properties were the Inflammatory Bowel Disease Questionnaire, Symptoms and Impacts Questionnaire for UC, UC-PRO symptoms modules, UC-PRO impact modules, and Crohn's and UC Questionnaire; all had good or excellent support for content validity. The UC-PRO Signs and Symptoms fully met FDA guidance and COSMIN criteria for content validity and most psychometric properties. CONCLUSION Existing PRO measures assess concepts relevant to patients with UC, but all PRO measures reviewed require further psychometric evaluation to demonstrate they are fit for purpose.

Abstract
AIM To assess whether oral health problems affect disease-specific quality of life (QoL) of inflammatory bowel disease (IBD) patients, and vice versa, whether IBD affects oral-health-related QoL. MATERIALS AND METHODS Individuals reporting IBD and matched controls were surveyed on general anamnestic information, oral-health-related questions and the Oral Health Impact Profile (OHIP)-5. IBD patients were additionally surveyed on years since diagnosis, disease activity and severity as well as health-related QoL (Short Inflammatory Bowel Disease Questionnaire, sIBDQ). OHIP-5 and sIBDQ were defined as primary outcome parameters, and several predictors and confounders were used in adjusted univariable and multivariable regression analyses. RESULTS Answers from 1108 IBD patients and 3429 controls were analysed. Compared with controls, IBD patients reported significantly more frequently an oral impact on daily life and worse oral-health-related QoL, with Crohn's disease (CD) patients being more severely affected than ulcerative colitis (UC) patients. The diagnosis of UC and CD, having <20 teeth, severe periodontitis and stressful daily-life experience were associated with a higher prevalence of poor oral-health-related QoL. Among IBD patients, an impaired IBD-specific, health-related QoL was significantly associated with the diagnosis of CD and depression, IBD activity and severity, having <20 teeth, presence of oral lesions and stressful daily-life experience, while a longer time since diagnosis was significantly associated with an improved IBD-specific, health-related QoL. CONCLUSIONS The results of the present study indicate, for the first time, that oral health problems are associated with an impairment of IBD-specific health-related QoL, and vice versa, IBD is associated with an impaired oral health-related QoL. This emphasizes the potential advantages of including dental professionals in the multi-disciplinary treatment teams of IBD patients.

Abstract
Background This study aimed to evaluate the psychometric properties of the Chinese version of the Short Inflammatory Bowel Disease Questionnaire (C-SIBDQ), and its measurement invariance across sex in Chinese patients with inflammatory bowel disease (IBD). Methods Between September 2018 and July 2021, 284 patients with IBD were recruited from a spleen and stomach clinic. All participants completed the C-SIBDQ, 12-item Short-Form Health Survey (SF-12), nine-item Patient Health Questionnaire Depression Scale (PHQ-9), and the seven-item Generalized Anxiety Disorder Scale (GAD-7). Floor and ceiling effects were evaluated by testing frequencies and composition ratios for the minimum and maximum C-SIBDQ scores. Exploratory and confirmatory factor analysis (CFA) were used to evaluate the C-SIBDQ’s factor structure and construct validity. Convergent validity was evaluated through examining bivariate correlations between the C-SIBDQ and the SF-12, PHQ-9, and GAD-7. Internal consistency reliability and retest reliability were evaluated by respectively calculating the Cronbach’s α and the intraclass correlation coefficient (ICC) among a subsample (n = 79) after 2 weeks. The measurement invariance across sex was evaluated through multiple-group CFA. Results The C-SIBDQ scores showed no floor or ceiling effects and had a single-factor structure and good convergent validity, with significant correlations with the SF-12, PHQ-9 and GAD-7. Good internal consistency (Cronbach’s α = 0.920) and test–retest reliability (ICC = 959) were observed. The C-SIBDQ also showed measurement invariance across sex, and females showed higher C-SIBDQ scores than males. Conclusions The C-SIBDQ has high reliability, validity, and stability across sex, and can be used in clinics to assess the health-related quality of life of patients with IBD.

Abstract
Peripheral artery disease (PAD) is a progressive atherosclerotic disease associated with high rates of morbidity and mortality. Symptomatic PAD typically presents with claudication, and symptom severity strongly associates with reduced health-related quality of life (HRQoL). Existing treatment strategies for PAD are aimed at reducing symptom severity and improving functional outcomes. However, there is a need to incorporate patient-reported outcome measures (PROMs) into PAD treatment and research in order to provide more patient-centered care. This review will discuss the impact of PAD on HRQoL, existing PROMs available to assess PAD-related HRQoL, utilization of PROMs in research studies and registries, and challenges and solutions related to the integration of PROMs into research and clinical settings.

Abstract
BACKGROUND AND PURPOSE To assess bowel dose-volume relationships for acute patient-reported intestinal symptoms of patients treated with whole-pelvis intensity-modulated radiotherapy (WPRT) for prostate cancer. MATERIALS AND METHODS Complete data of 415 patients enrolled in a multi institute, prospective trial (#NCT02803086) treated with radical (31%), adjuvant (33%) and salvage (36%) intent at a median dose to pelvic nodes/lymph-nodal area of 53 Gy were available. The most severe changes between baseline and radiotherapy mid-point/end toxicity assessed by Inflammatory Bowel Disease Questionnaire (only Bowel Domain) were considered (ΔIBDQ). The 25th percentile values of these score variations were set as endpoints. DVHs of bowel loops for patients with/without toxicity were compared for each endpoint, having excluded patients with baseline scores <5 (rate ranging between 2% and 7% according to the endpoint): the resulting best dosimetric predictors were combined with selected clinical parameters through multivariate logistic regression (MVA) to derive predictive models. RESULTS ΔIBDQ ranged between 0.2-1.5 points considering separately each IBDQ symptom. Only four symptoms (IBDQ1 = frequency, IBDQ5 = diarrhea, IBDQ17 = gas passage, IBDQ24 = urgency) showed a median worsening ≥ 1; DVH predicted the risk of worse symptoms for IBDQ5, IBDQ24 and overall Bowel Domain. At multivariable analysis DVHs (best cut-off: V46Gy ≥80 cc) and baseline scores (Odd-Ratio:0.35-0.65) were independently associated to the three end-points. The resulting models were reliable (H&L test: 0.453-0.956), well calibrated (calibration plot: slope = 0.922-1.069, R2 = 0.725-0.875) and moderately discriminative (Area Under the Curve:0.628-0.669). A bootstrap-based validation confirmed their robustness. CONCLUSION Constraining the bowel loops (V46 < 80 cc) may reduce the risk of several moderate intestinal symptoms, with a much greater impact for patients with lower IBDQ baseline scores.

Short Inflammatory Bowel Disease Questionnaire: translation and validation to the Portuguese language. Health Qual Life Outcomes 2021; 19:59.

Abstract
BACKGROUND The Short Inflammatory Bowel Disease Questionnaire (SIBDQ) is a widely used instrument to assess Health-related Quality of Life (HRQoL) among inflammatory bowel disease (IBD) patients. Our aim was to translate and adapt the SIBDQ so that it could be adequately used in Portugal. METHODS This is a prospective design cohort study undertaken at a tertiary hospital. This study took place simultaneously with the first part of the SexIDI study, a study aiming to assess the impact of IBD on patients' sexual QoL. The original SIBDQ was translated by two independent translators and adapted by an IBD expert panel following the opinions of a convenient sample of 5 IBD patients. Afterwards, IBD patients from the outpatient clinic were consecutively invited to fill the Portuguese version of the questionnaire (SIBDQ-PT) at three different timepoints (0, 2, 4 weeks). Ninety-two patients completed the SIBDQ-PT at baseline, whereas 33 did so after 2 and 4 weeks (approximately). Statistical analysis was performed using SPSS version 25, and the following aspects were analysed: reliability (through internal consistency, test-retest and intraclass correlation), validity (through exploratory factor analysis [EFA], and Pearson correlation coefficient for linear correlations), score distribution, and responsiveness analysis (through t-student tests). RESULTS Overall, SIBDQ-PT was shown to have a high internal consistency (Cronbach's α = 0.80) and a high test-retest reliability (0.80 [CI 0.74-0.86] and 0.69 [CI 0.50-0.82]). EFA detected four dimensions-bowel, social, emotional and systemic. As expected, an overall SIBDQ-PT score was positively correlated with sexual satisfaction (r = 0.27; p < 0.05) and negatively correlated with depression (r = - 0.63; p < 0.01). Moreover, SIBDQ-PT was found to have an adequate score distribution, and to be responsive, as there was a significant subscore change for patients who reported an "overall worsening in general well-being" (0.93 ± 0.13 decrease; p < 0.01). CONCLUSIONS The Portuguese version of the SIBDQ hereby presented is a reliable, valid and responsive instrument that can be used to measure HRQoL among Portuguese IBD patients.

Abstract
BACKGROUND AND AIMS Patient-reported outcome measures are increasingly important in daily care and research in inflammatory bowel disease [IBD]. This study provides an overview of the content and content validity of IBD-specific patient-reported outcome measures on three selected constructs. METHODS Databases were searched up to May 2019 for development and/or content validity studies on IBD-specific self-report measures on health-related quality of life, disability, and self-report disease activity in adults. Evidence was synthesised on content validity in three aspects: relevance, comprehensiveness, and comprehensibility following the COnsensus-based Standards for the selection of health Measurement INstruments methodology. Questionnaire items were organised in themes to provide an overview of important aspects of these constructs. RESULTS For 14/44 instruments, 25 content validity studies were identified and 25/44 measures had sufficient content validity, the strongest evidence being of moderate quality, though most evidence is of low or very low quality. The Crohn's Life Impact Questionnaire and IBD questionnaire-32 on quality of life, the IBD-Control on disease activity, and the IBD Disability Index Self-Report and its 8-item version on disability, have the strongest evidence of sufficient relevance, comprehensiveness, and comprehensibility, ranging from moderate to very low quality. A fair number of recurring items themes, possibly important for the selected constructs, was identified. CONCLUSIONS The body of evidence for content validity of IBD-specific health-related quality of life, self-report disease activity, and disability self-report measures is limited. More content validity studies should be performed after reaching consensus on the constructs of interest for IBD, and studies should involve patients.

Abstract
BACKGROUND/AIMS Inflammatory bowel diseases (IBD) impairs patients' quality of life (QoL). Inflammatory bowel disease questionnaire (IBDQ) is created to measure the health-related QoL specific for IBD. We planned to investigate the validation and reliability of the Turkish translation of IBDQ. MATERIALS AND METHODS Patients filled self-report questionnaires (Turkish Inflammatory bowel disease questionnaire (TrIBDQ) and Short Form-36 (SF-36)) themselves under a physician's supervision, and they were free to ask questions about the questionnaires. The participants then filled the same questionnaire after at least two weeks. Construct validity, discriminant ability, reliability, and susceptibility to change were analyzed separately for the IBD patients. Intra-class correlation coefficient (ICC) was used to assess test-retest reliability. Cronbach's alpha values were used to assess internal consistency. RESULTS A hundred patients enrolled in the study, 53 with Crohn's disease (CD), 47 with ulcerative colitis (UC). We found a moderate to high positive correlation between the TrIBDQ domains and the SF-36 dimensions. In UC and CD, TrIBDQ was able to differentiate active disease and remission. We found Cronbach's alpha for TrIBDQ domains ranged from 0.76-0.94 in CD and from 0.79-0.92 in UC. The total Cronbach's alpha for TrIBDQ was 0.96 in CD and 0.95 in UC. Sensitivity-to-change analyses of the bowel, systemic, and emotional scores showed statistically significant differences between their baseline and follow-up values. CONCLUSION TrIBDQ is a valid and reliable tool for assessing the quality of life in Turkish speaking IBD patients. Thus it can be used in clinical research and practice.

Abstract
Patients' cognitions about their disease and treatment are important mediators between health and quality of life of patients with chronic diseases and also explain the occurrence of individual differences in individuals' adjustment to chronic disease. The aim of this study was to examine the relationship between illness cognitions and health-related quality of life among adult patients with inflammatory bowel disease. Self-report data on illness cognition and health-related quality of life were collected from 118 people with Crohn disease or ulcerative colitis. Illness cognition of greater helplessness significantly predicted health-related quality of life in patients with inflammatory bowel disease. A relative contribution of acceptance and perceived benefits was not confirmed as a predictor of health-related quality of life. The other variables (type of disease, duration of disease, age, and episode of relapses) did not have statistical significance, except for gender. Results demonstrate that experiencing helplessness in relation to the disease, its treatment, and consequences can be generalized to patients in all areas of daily life, leading to deterioration in their overall psychological and physical functioning. These results can provide useful indicators of potential patient's adherence in treatment and self-management of inflammatory bowel disease.

Abstract
Objectives: To identify and classify tools for assessing the influence of neurogenic bowel dysfunction (NBD) on quality of life (QoL) after spinal cord injury (SCI). Methods: In this systematic review, MEDLINE/PubMed, CINAHL, and PsycInfo were searched to identify studies assessing the influence of NBD on QoL (or related construct) after SCI. Two independent reviewers screened titles and abstracts, and both reviewers classified tools as subjective or objective according to Dijkers' theoretical QoL framework. Results: Seventy-two studies were identified, and 35 studies met the inclusion criteria. Five objective measures assessed the influence of NBD on QoL, which were validated for use in SCI, but no measure was condition-specific to NBD. Eight measures were classified as subjective tools; two had an established reliability and validity for SCI while six had some psychometric evidence for use in the SCI population. Five subjective measures (NBD score, Burwood QoL Questionnaire, Impediments to Community Integration [ICI] Scale, SCI-QoL Bowel Management Difficulties, and Survey of Neurogenic Bowel Characteristics) were developed specifically for SCI. The NBD score showed sensitivity to the influence of NBD on QoL in experimental trials. Conclusion: Thirteen tools assessed the influence of NBD on QoL in SCI. Although not developed specifically for SCI, the Health Utility Index (HUI-III) was the only tool identified that provided data on "QoL as utility" on the impact of NBD. The validated NBD score was the only condition-specific tool to assess QoL as "subjective well-being." Further validation of existing tools could help to inform practice and policy related to resource allocation for bowel care post SCI.

Abstract
BACKGROUND The efficacy of infliximab and ciclosporin in treating severe ulcerative colitis (UC) is proven, but there has been no comparative evaluation of effectiveness. OBJECTIVE To compare the clinical effectiveness and cost-effectiveness of infliximab and ciclosporin in treating steroid-resistant acute severe UC. METHOD Between May 2010 and February 2013 we recruited 270 participants from 52 hospitals in England, Scotland and Wales to an open-label parallel-group, pragmatic randomised trial. Consented patients admitted with severe colitis completed baseline quality-of-life questionnaires before receiving intravenous hydrocortisone. If they failed to respond within about 5 days, and met other inclusion criteria, we invited them to participate and used a web-based adaptive randomisation algorithm to allocate them in equal proportions between 5 mg/kg of intravenous infliximab at 0, 2 and 6 weeks or 2 mg/kg/day of intravenous ciclosporin for 7 days followed by 5.5 mg/kg/day of oral ciclosporin until 12 weeks from randomisation. Further treatment was at the discretion of physicians responsible for clinical management. The primary outcome was quality-adjusted survival (QAS): the area under the curve (AUC) of scores derived from Crohn's and Ulcerative Colitis Questionnaires completed by participants at 3 and 6 months, and then 6-monthly over 1-3 years, more frequently after surgery. Secondary outcomes collected simultaneously included European Quality of Life-5 Dimensions (EQ-5D) scores and NHS resource use to estimate cost-effectiveness. Blinding was possible only for data analysts. We interviewed 20 trial participants and 23 participating professionals. Funded data collection finished in March 2014. Most participants consented to complete annual questionnaires and for us to analyse their routinely collected health data over 10 years. RESULTS The 135 participants in each group were well matched at baseline. In 121 participants analysed in each group, we found no significant difference between infliximab and ciclosporin in QAS [mean difference in AUC/day 0.0297 favouring ciclosporin, 95% confidence interval (CI) -0.0088 to 0.0682; p = 0.129]; EQ-5D scores (quality-adjusted life-year mean difference 0.021 favouring ciclosporin, 95% CI -0.032 to 0.096; p = 0.350); Short Form questionnaire-6 Dimensions scores (mean difference 0.0051 favouring ciclosporin, 95% CI -0.0250 to 0.0353; p = 0.737). There was no statistically significant difference in colectomy rates [odds ratio (OR) 1.350 favouring infliximab, 95% CI 0.832 to 2.188; p = 0.223]; numbers of serious adverse reactions (event ratio = 0.938 favouring ciclosporin, 95% CI 0.590 to 1.493; p = 0.788); participants with serious adverse reactions (OR 0.660 favouring ciclosporin, 95% CI 0.282 to 1.546; p = 0.338); numbers of serious adverse events (event ratio 1.075 favouring infliximab, 95% CI 0.603 to 1.917; p = 0.807); participants with serious adverse events (OR 0.999 favouring infliximab, 95% CI 0.473 to 2.114; p = 0.998); deaths (all three who died received infliximab; p = 0.247) or concomitant use of immunosuppressants. The lower cost of ciclosporin led to lower total NHS costs (mean difference -£5632, 95% CI -£8305 to -£2773; p < 0.001). Interviews highlighted the debilitating effect of UC; participants were more positive about infliximab than ciclosporin. Professionals reported advantages and disadvantages with both drugs, but nurses disliked the intravenous ciclosporin. CONCLUSIONS Total cost to the NHS was considerably higher for infliximab than ciclosporin. Nevertheless, there was no significant difference between the two drugs in clinical effectiveness, colectomy rates, incidence of SAEs or reactions, or mortality, when measured 1-3 years post treatment. To assess long-term outcome participants will be followed up for 10 years post randomisation, using questionnaires and routinely collected data. Further studies will be needed to evaluate the efficacy and effectiveness of new anti-tumour necrosis factor drugs and formulations of ciclosporin.

Abstract
Background This review aims to critically appraise and compare the measurement properties of inflammatory bowel disease (IBD)-specific health-related quality of life instruments. Methods Medline, EMBASE and ISI Web of Knowledge were searched from their inception to May 2016. IBD-specific instruments for patients with Crohn’s disease, ulcerative colitis or IBD were enrolled. The basic characteristics and domains of the instruments were collected. The methodological quality of measurement properties and measurement properties of the instruments were assessed. Results Fifteen IBD-specific instruments were included, which included twelve instruments for adult IBD patients and three for paediatric IBD patients. All of the instruments were developed in North American and European countries. The following common domains were identified: IBD-related symptoms, physical, emotional and social domain. The methodological quality was satisfactory for content validity; fair in internal consistency, reliability, structural validity, hypotheses testing and criterion validity; and poor in measurement error, cross-cultural validity and responsiveness. For adult IBD patients, the IBDQ-32 and its short version (SIBDQ) had good measurement properties and were the most widely used worldwide. For paediatric IBD patients, the IMPACT-III had good measurement properties and had more translated versions. Conclusions Most methodological quality should be promoted, especially measurement error, cross-cultural validity and responsiveness. The IBDQ-32 was the most widely used instrument with good reliability and validity, followed by the SIBDQ and IMPACT-III. Further validation studies are necessary to support the use of other instruments.

Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic inflammatory disorder of the colon that has a relapsing-remitting course. Health related quality of life (HRQL) is significantly lower in patients with UC than the general population due to the negative effects of the disease on physical, psychological and social well-being. Randomized controlled trials (RCTs) evaluating medical interventions for UC have traditionally used clinical disease activity indices that focus on symptoms to define primary outcomes such as clinical remission or improvement. However, this approach does not evaluate benefits that are highly relevant to patients such as HRQL OBJECTIVES: The primary objective was to assess the impact of biologic therapy on the HRQL of UC patients. SEARCH METHODS We searched PubMed, MEDLINE, EMBASE and CENTRAL from inception to September, 2015. Conference abstracts and reference lists were also searched. SELECTION CRITERIA RCTs that compared biologics to placebo in UC patients and reported on HRQL using the Inflammatory Bowel Disease Questionnaire (IBDQ), or the SF-36 or EQ-5D to measure HRQL were included. DATA COLLECTION AND ANALYSIS Two authors independently screened studies for inclusion, extracted data and assessed study quality using the Cochrane risk of bias tool. The primary outcome was improvement in HRQL. For dichotomous outcomes we calculated the risk ratio (RR) and 95% confidence interval (CI). For continuous outcomes we calculated the mean difference (MD) and 95% CI. The overall quality of the evidence supporting the primary outcome was assessed using GRADE. MAIN RESULTS Nine RCTs (n = 4143) were included. Biologics included rituximab (one small study), interferon-ß-1a (one study), vedolizumab (one study), and the tumor necrosis factor-alpha (TNF-α) antagonists infliximab (two studies), adalimumab (three studies), and golimumab (one study). Risk of bias was low in eight studies. The rituximab study was judged to be at high risk of bias due to attrition bias. The studies comparing interferon-ß-1a and rituximab to placebo found no clear evidence of a difference in the proportion of patients who experienced an improvement in HRQL at 8 or 12 weeks respectively. The proportion of patients with a clinically meaningful improvement in HRQL at 6 or 52 weeks was significantly higher in vedolizumab patients compared to placebo. At 6 weeks 37% (83/225) of vedolizumab patients had an improvement in IBDQ score of at least 16 points from baseline compared to 23% (34/149) of placebo patients (RR 1.62, 95% CI 1.15 to 2.27; 1 study). At 52 weeks, 64% (157/247) of vedolizumab patients had an improvement in IBDQ score of at least 16 points from baseline compared to 38% (48/126) of placebo patients (RR 1.62, 95% CI 1.15 to 2.27; 1 study). A GRADE analysis indicated that the overall quality of the evidence supporting these outcomes was moderate due to sparse data (< 400 events). Patients who received maintenance vedolizumab every eight weeks had significantly higher mean SF-36 scores than placebo patients at 52 weeks (MD 3.40, 95% CI 1.56 to 5.24, 1 study 248 patients). This difference appears to be clinically meaningful as the lower boundary for a clinically meaningful change in SF-36 is three points. A GRADE analysis indicated that the overall quality of the evidence supporting this outcome was moderate due to sparse data (< 400 events). Adalimumab patients had significantly higher mean IBDQ scores than placebo patients at weeks 8 (MD 9.00, 95% CI 2.65 to 15.35; 1 study, 494 patients) and 52 (MD 8.00, 95% CI 0.68 to 15.32; 1 study, 494 patients). However, these differences may not be clinically meaningful as the lower boundary for a clinically meaningful change in IBDQ is 16 points. A GRADE analysis indicated that the overall quality of the evidence supporting this outcome was moderate due to sparse data (< 400 events). Golimumab patients who received a dose of 200/100 mg (MD 12.20, 95% CI 6.52 to 17.88; 504 patients) or 400/200 mg (MD 12.10, 95% CI 6.40 to 17.80; 508 patients) had significantly higher mean IBDQ scores than placebo patients at week 6. Although a GRADE analysis indicated that the overall quality of the evidence supporting these outcomes was high, the difference in IBDQ scores may not be clinically meaningful. Infliximab patients had significantly higher mean IBDQ scores at week 6 or 8 than placebo patients (MD 18,58, 95% CI 13.19 to 23.97; 2 studies, 529 patients). This difference in HRQL is clinically meaningful. A GRADE analysis indicated that the overall quality of the evidence supporting this outcome was high. The proportion of patients with a clinically meaningful improvement in HRQL at eight weeks was significantly higher in infliximab patients compared to placebo. Sixty-nine per cent (333/484) of infliximab patients had an improvement in IBDQ score of > 16 points from baseline compared to 50% of placebo patients (RR 1.39, 95% CI 1.21 to 1.60; 1 study). A GRADE analysis indicated that the overall quality of the evidence supporting this outcome was high. Similar results were found between infliximab and placebo when HRQL was measured using the SF-36 instrument. One small study (n = 43) found no difference in HRQL between infliximab and placebo when measured by the EQ-5D. Pooled analyses of TNF-α antagonists showed a benefit in HRQL favouring TNF-α over placebo. AUTHORS' CONCLUSIONS These results suggest that biologics have the potential to improve HRQL in UC patients. High quality evidence suggests that infliximab provides a clinically meaningful improvement in HRQL in UC patients receiving induction therapy. Moderate quality evidence suggests that vedolizumab provides a clinically meaningful improvement in HRQL in UC patients receiving maintenance therapy. These findings are important since there is a paucity of effective drugs for the treatment of UC that have the potential to both decrease disease activity and improve HRQL. More research is needed to assess the long-term effect of biologic therapy on HRQL in patients with UC. More research is needed to assess the impact of golimumab and adalimumab on HRQL in UC patients. Trials involving direct head to head comparisons of biologics would help determine which biologics provide optimum benefit for HRQL.

Abstract
BACKGROUND AND AIMS Most of the disease-specific quality of life (QoL) measures for inflammatory bowel disease (IBD) are lengthy and time consuming. None have been established for routine use in clinical practice. We designed this study to develop a short QoL measure in IBD. METHODS A 32-item questionnaire, the Crohn's and ulcerative colitis questionnaire (CUCQ)-32 was developed by reviewing the literature of the previously validated questionnaires and by consultation with patients and experts. Construct validity was carried out using the Short Form 12 and the EuroQol 5 dimensions questionnaires and two disease severity measures (the Simple Clinical Colitis Activity Index and the Harvey-Bradshaw Index). Test-retest analysis was done by asking patients to complete the CUCQ questionnaire twice within a period of two weeks. RESULTS Data were obtained from 205 patients with IBD who completed the CUCQ-32. Psychometric analysis showed that Cronbach's α was 0.88, item-total correlations were good, and there were no ceiling or flooring effects. Stepwise regression identified eight items that accounted for >95% of the variance in the CUCQ-32. The resulting CUCQ-8 demonstrated good internal consistency (Cronbach's α = 0.84), had good reproducibility (intraclass correlation coefficient = 0.94), was well correlated with the EuroQol 5 dimensions questionnaire (r = 0.58) and the Short Form-12 (r = 0.65 for physical component and r = 0.63 for mental component), and was responsive to change (responsiveness ratio was 0.64, p-value < 0.05). CONCLUSIONS CUCQ-8 is a short questionnaire that has the potential to be an efficient tool for assessing the QoL of all patients with IBD in clinical practice.

Abstract
Background The chronic nature of inflammatory bowel disease leads to considerable impairment on the health related quality of life (HRQOL). The aims of the present study are to validate the mainland Chinese translation of the Inflammatory Bowel Disease Questionnaire (MCIBDQ), and to evaluate the impact of infliximab treatment on HRQOL in patients with IBD for the first time in China, as compared with other therapies of different levels. Furthermore, the impact of different medical therapies on marriage, employment and economic burden in IBD patients were also evaluated. Methods Consecutive patients who met inclusion/exclusion criteria were investigated with MCIBDQ, SF-36, disease activity index (DAI), marriage, employment and economic burden questionnaires before and after treatment. Results MCIBDQ showed significant reliability and validity both in CD and UC patients. The scores of total SF-36, total MCIBDQ and all domains were found significantly increased, while both DAI and health transition on general health scores were found significantly decreased after infliximab treatment (all P < 0.001). Scores of SF-36 and MCIBDQ increased significantly more in infliximab group than non-infliximab group (all P < 0.05). Infliximab treatment was suggested to significantly reduce the negative impact on love (P = 0.037), increase work time (P = 0.016) and ease economic burden (P = 0.048). Conclusions MCIBDQ was demonstrated to be a reliable and valid scale applied in Chinese IBD patients. Infliximab treatment was found to significantly improve HRQOL in IBD patients in comparison with conventional treatments. Negative impact on marriage, employment, and economic status was found in patients with IBD.

Abstract
BACKGROUND & AIMS Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe. METHODS The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.1 million. Patients answered the disease specific Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and generic Short Form 12 (SF-12) questionnaire at diagnosis and after one year of follow-up. RESULTS In total, 1079 patients were included in this study. Crohn's disease (CD) patients mean SIBDQ scores improved from 45.3 to 55.3 in Eastern Europe and from 44.9 to 53.6 in Western Europe. SIBDQ scores for ulcerative colitis (UC) patients improved from 44.9 to 57.4 and from 48.8 to 55.7, respectively. UC patients needing surgery or biologicals had lower SIBDQ scores before and after compared to the rest, while biological therapy improved SIBDQ scores in CD. CD and UC patients in both regions improved all SF-12 scores. Only Eastern European UC patients achieved SF-12 summary scores equal to or above the normal population. CONCLUSION Medical and surgical treatment improved HRQoL during the first year of disease. The majority of IBD patients in both Eastern and Western Europe reported a positive perception of disease-specific but not generic HRQoL. Biological therapy improved HRQoL in CD patients, while UC patients in need of surgery or biological therapy experienced lower perceptions of HRQoL than the rest.

Abstract
OBJECTIVE To assess the effectiveness of solution-focused therapy (SFT) on fatigue and quality of life (QoL) in patients with fatigued inflammatory bowel disease (IBD). DESIGN Randomised controlled trial in two Dutch hospitals. Patients with IBD with quiescent IBD and with a Checklist Individual Strength--Fatigue (CIS--fatigue) score of ≥ 35 were enrolled. Patients were 1:1 randomised to receive SFT or care as usual (CAU) for 3 months. Patients were followed for a further 6 months after the SFT. Primary endpoint was defined as changes in fatigue and QoL during follow-up. Secondary endpoints included change in anxiety and depression, medication use, side effects to medication, disease activity, laboratory parameters (C-reactive protein, leucocytes and haemoglobin) and sleep quality. RESULTS Ninety-eight patients were included, of whom 63% were women, mean age was 40.1 years. After the SFT course, 17 (39%) patients in the SFT group had a CIS-fatigue score below 35 compared with eight (18%) of patients in the CAU group (p=0.03). The SFT group also showed a greater reduction in fatigue across the first 6 months compared with the CAU group (CIS-fatigue: p=<0.001 and CIS-total: p=0.001). SFT was associated with a significant higher mean IBD questionnaire change at 3 months (p=0.020). At 9 months, no significant differences between the two groups were observed. CONCLUSIONS SFT has a significant beneficial effect on the severity of fatigue and QoL in patients with quiescent IBD. However, this effect diminished during follow-up.

Abstract
OBJECTIVE To assess whether a combination of adalimumab and ciprofloxacin is superior to adalimumab alone in the treatment of perianal fistulising Crohn's disease (CD). DESIGN Randomised, double-blind, placebo controlled trial in eight Dutch hospitals. In total, 76 CD patients with active perianal fistulising disease were enrolled. After adalimumab induction therapy (160/80 mg week 0, 2), patients received 40 mg every other week together with ciprofloxacin 500 mg or placebo twice daily for 12 weeks. After 12 weeks, adalimumab was continued. Follow-up was 24 weeks. Primary endpoint (clinical response) was defined as 50% reduction of fistulas from baseline to week 12. Secondary endpoints included remission (closure of all fistulas), Perianal Crohn's Disease Activity Index, Crohn's Disease Activity Index (CDAI) and Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS Clinical response was observed in 71% of patients treated with adalimumab plus ciprofloxacin and in 47% treated with adalimumab plus placebo (p=0.047). Likewise, remission rate at week 12 was significantly higher (p=0.009) in the combination group (65%) compared with adalimumab plus placebo (33%). Combination treatment was associated with a higher mean CDAI change and mean IBDQ change at week 12 (p=0.005 and p=0.009, respectively). At week 24, no difference in clinical response between the two treatment groups was observed (p=0.22). No difference in safety issues was observed. CONCLUSIONS Combination therapy of adalimumab and ciprofloxacin is more effective than adalimumab monotherapy to achieve fistula closure in CD. However, after discontinuation of antibiotic therapy, the beneficial effect of initial coadministration is not maintained. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT00736983.

Abstract
Background/Aims Gastroesophageal reflux disease is a highly prevalent disease. Assessing treatment efficacy is critical in that clinical endpoints are properly evaluated. Clinical tools for symptoms severity assessment should be discriminative, predictive and evaluative. Methods In this study we compared a patient-oriented symptoms evaluation (ReQuest™) vs a structured interview assessment initiated by a physician (sickness impact profile [SIP]). Both questionnaires were analyzed in a multidimensional space using latent factors. Five dimensions were found: 1 for the short ReQuest™ questionnaire and 4 for SIP. Results We included 1,522 women and 1,296 men; mean age was 36 ± 7 years, and mean body mass index was 26 ± 4. The score questionnaire assessment evaluation by physicians and patients did not correlate between them (between r = 0.03 and 0.26) except nausea and sleep disorder (r = 0.45 and 0.51) but both were sensitive enough to detect changes after treatment (P < 0.05). Medical specialty of the physician showed effect on the score of both, ReQuest™ and SIP evaluation. Questionnaire variance decomposition due to specialist was only 2% (P < 0.05). Conclusions While both evaluations are orthogonal (non-correlated), meaning patients and physicians measured diverse aspects of the same disease, they both were able to measure patient's improvement with treatment.

Abstract
Background Patient-reported outcomes are measured in many epidemiologic studies using self- or interviewer-administered questionnaires. While in some studies differences between these administration formats were observed, other studies did not show statistically significant differences important to patients. Since the evidence about the effect of administration format is inconsistent and mainly available from cross-sectional studies our aim was to assess the effects of different administration formats on repeated measurements of patient-reported outcomes in participants with AIDS enrolled in the Longitudinal Study of Ocular Complications of AIDS. Methods We included participants enrolled in the Longitudinal Study of Ocular Complications in AIDS (LSOCA) who completed the Medical Outcome Study [MOS] -HIV questionnaire, the EuroQol, the Feeling Thermometer and the Visual Function Questionnaire (VFQ) 25 every six months thereafter using self- or interviewer-administration. A large print questionnaire was available for participants with visual impairment. Considering all measurements over time and adjusting for patient and study site characteristics we used linear models to compare HRQL scores (all scores from 0-100) between administration formats. We defined adjusted differences of ≥0.2 standard deviations [SD]) to be quantitatively meaningful. Results We included 2,261 participants (80.6% males) with a median of 43.1 years of age at enrolment who provided data on 23,420 study visits. The self-administered MOS-HIV, Feeling Thermometer and EuroQol were used in 70% of all visits and the VFQ-25 in 80%. For eight domains of the MOS-HIV differences between the interviewer- and self- administered format were < 0.1 SD. Differences in scores were highest for the social and role function domains but the adjusted differences were still < 0.2 SD. There was no quantitatively meaningful difference between administration formats for EuroQol, Feeling Thermometer and VFQ-25 domain scores. For ocular pain (VFQ-25), we found a statistically significant difference of 3.5 (95% CI 0.2, 6.8), which did, however, not exceed 0.2 SD. For all instruments scores were similar for the large and standard print formats with all adjusted differences < 0.2 SD. Conclusions Our large study provides evidence that administration formats do not have a meaningful effect on repeated measurements of patient-reported outcomes. As a consequence, longitudinal studies may not need to consider the effect of different administration formats in their analyses.

Abstract
BACKGROUND Successful treatment of systemic inflammatory symptoms is essential for improving health-related quality of life in patients with active Crohn's disease. Patient-reported outcomes provide unique perspectives on the impact of chronic disease. It is unknown whether a combination of different instruments might improve sensitivity to clinically relevant changes in health status. AIM To develop a composite score based upon Crohn's Disease Activity Index (CDAI) and Inflammatory Bowel Disease Questionnaire (IBDQ) items. METHODS Patients from the PRECiSE 2 trial who responded at week 6 to certolizumab pegol (CZP) were randomised to receive treatment with CZP 400 mg or placebo for up to 26 weeks. IBDQ and CDAI scores were assessed at weeks 0, 6, 16 and 26. A 'daily practice' composite score (DP-6) containing two items from the CDAI and four items from IBDQ was constructed. RESULTS Correlation coefficients between the CDAI score and IBDQ total score at baseline and at week 26 were -0.344 and -0.603, respectively (P<0.05). All IBDQ items were improved following CZP treatment. The DP-6 had the highest responsiveness at assessing response to treatment, relative to CDAI total score, when compared with other scores. CONCLUSIONS The DP-6 composite score could be used to optimise the use of existing instruments by serving as an index of symptoms due to systemic inflammation. Additional studies are needed to determine if the DP-6 composite score differentiates the impact of different treatments on patient-reported outcomes, and to determine if the use of the DP-6 improves the care of patients in clinical practice.

Abstract
BACKGROUND The Short Inflammatory Bowel Disease Questionnaire (SIBDQ) is a written, self-administered instrument measuring quality of life in IBD. We assessed the validity of an interactive voice response system (IVRS) as a new mode of administering the SIBDQ. METHODS An IVRS was designed using prerecorded questions to collect data via touchtone telephone. Subjects with Crohn's disease (CD) or ulcerative colitis (UC) were randomized into 2 groups with different orders of administration: written, self-administered followed by IVRS (S-I) or IVRS followed by written, self-administered (I-S). Half of the S-I group was also randomized to receive a second IVRS. Sixty-four subjects were studied: 30 in S-I, 34 in I-S. RESULTS The mean SIBDQ scores were not different between written and IVRS modes (P = 0.26) with r = 0.93. IVRS scores were lower in active than inactive CD (36.1 +/- 9.6 versus 54.7 +/- 8.6, P < 0.001) and lower in active than inactive UC (40.8 +/- 9.6 versus 59.8 +/- 10.0, P < 0.001). Mean scores correlated highly with disease activity indices, and were not different between first and second IVRS administrations (P = 0.85) with r = 0.92. IVRS had excellent internal consistency (Cronbach alpha = 0.90). CONCLUSIONS IVRS administration of the SIBDQ yields results similar to written self-administration, with excellent procedural validity, test-retest reliability, and internal consistency.

Abstract
BACKGROUND Inflammatory bowel disease affects the quality of a patient's life in many ways, but no validated instrument for measuring disease-specific quality of life in these patients is available for use in Mainland China. The aim of our study was to develop and validate the Mainland Chinese translation of the Inflammatory Bowel Disease Questionnaire for ulcerative colitis (UC) and Crohn's disease (CD) by assessing its construct validity, discriminant ability, reliability, and sensitivity to change. METHODS We administered a developed Mainland Chinese version of the Inflammatory Bowel Disease Questionnaire (IBDQ). Ninety-two Mainland Chinese patients (52 with UC and 40 with CD) completed the Mainland Chinese version of the IBDQ, the Chinese version of SF-36, and the global scale for general well-being. A subgroup of 71 patients also completed the Mainland Chinese version of the IBDQ and the global scales for general well-being on a second occasion. Clinical activity was assessed by the Walmsley and Harvey-Bradshaw simple indices. RESULTS The Mainland Chinese IBDQ scores correlated well with the related SF-36 dimensional scores for all 4 domains (r = 0.51-0.82), SF-36 total scores (r = 0.58-0.87), the colitis activity index (r = -0.56-0.74), and the CD activity index (r = -0.64-0.78) as well as with the global scales. The Mainland Chinese IBDQ was able to discriminate between active and inactive disease. Cronbach's alpha was 0.95 in UC and 0.94 in CD. Test-retest reliability was excellent (intraclass correlation coefficient 0.69-0.93) when it was repeated in patients whose clinical activity index was stable. In contrast, there was a significant difference between the baseline and follow-up measurements in patients whose clinical activity index was changed. CONCLUSIONS The Mainland Chinese IBDQ proved to be a valid, discriminative, and reliable instrument for assessing health-related quality of life in patients with UC and CD in Mainland China.

Abstract
BACKGROUND & AIMS Tetomilast (OPC-6535), a novel thiazole compound, inhibits phosphodiesterase-4 and proinflammatory functions of leukocytes including superoxide production and cytokine release. METHODS One hundred eighty-six patients with mildly to moderately active ulcerative colitis (Disease Activity Index [DAI] 4-11 points) from 35 centers were randomized to receive an oral, once-daily dose of placebo or tetomilast 25 mg or 50 mg for 8 weeks. RESULTS Percentages of patients reaching the primary end point (improvement as defined by reduction in DAI > or =3 at week 8) were not significantly different between placebo (35%) and either the 25 mg tetomilast (52%) or the 50 mg tetomilast (39%) groups (intent-to-treat population). Remission rates (DAI 0-1) were 7%, 16%, and 21%, respectively (not significant). Mean reduction in DAI at week 8 was greater in the 25-mg group than under placebo (2.8 +/- 0.4 vs 1.7 +/- 0.36, respectively, P = .041) and approached statistical significance in the 50-mg group (2.8 +/- 0.46, P = .056). A post hoc analysis focusing on patients with high activity scores (baseline DAI 7-11) suggested differences between tetomilast and placebo that will require further investigation. No significant safety concerns were raised. Main adverse effects included gastrointestinal problems (nausea, vomiting) and were preferentially seen in the 50-mg tetomilast group. CONCLUSIONS This phase II trial of tetomilast in ulcerative colitis did not achieve statistical significance for the primary end point. Secondary end points indicate a potential clinical activity of tetomilast. The post hoc analysis suggests that further clinical development should focus on patients with objective parameters of inflammation.

Abstract
GOALS Two uncontrolled, multicenter feasibility studies evaluated safety and pilot efficacy of selective granulocyte and monocyte adsorption apheresis (GMA) with the Adacolumn Apheresis System for treatment of moderate-to-severe ulcerative colitis (UC) and Crohn disease (CD) patients refractory/intolerant to conventional pharmacologic therapy. BACKGROUND Patients with UC and CD, characterized by elevations in peripheral blood granulocytes, monocytes/macrophages, and proinflammatory mediators, may benefit from reductions in activated granulocytes and monocytes by selective apheresis. METHODS Patients underwent weekly Adacolumn sessions for 5 weeks. Pilot efficacy assessments used disease activity index (DAI) for UC (0-12) or CD activity index (CDAI; 0-600) for CD. RESULTS Eleven of 15 UC patients completed all 5 treatments. Mean DAI scores fell from 8.4+/-1.3 (baseline) to 5.2+/-2.9 (week 7). Five patients had DAI reductions of > or = 3 points at week 7. Fourteen of 15 CD patients completed all 5 treatments. Mean CDAI scores fell from 308.0+/-76.5 (baseline) to 200.6+/-117.4 (week 7). Nine CD patients responded (CDAI reductions > or = 70 points) at week 7. Remission (CDAI score < or = 150 at week 7) was observed in 6 patients. There were no device-related serious adverse effects. CONCLUSIONS Treatment with Adacolumn may be feasible and effective in patients with moderate-to-severe refractory inflammatory bowel disease. Larger sham-controlled studies are ongoing.

Abstract
BACKGROUND More than 50% of patients with Crohn's disease become either steroid resistant or dependent. Accordingly, development of new treatments for steroid-dependent Crohn's disease is a research priority. AIM To evaluate CDP571, a humanized antibody to tumour necrosis factor-alpha, for the treatment of steroid-dependent Crohn's disease. METHODS Patients with steroid-dependent Crohn's disease (n = 271) were enrolled in a 36-week, double-blind, placebo-controlled trial. Steroid dependence was defined as use of prednisolone or prednisone (15-40 mg/day) or budesonide (9 mg/day) for > or =8 weeks, a previous failed attempt to decrease or discontinue steroids within 8 weeks of screening, and a Crohn's Disease Activity Index score of < or =150 points. Patients were randomized to receive intravenous CDP571 10 mg/kg or placebo 8-weekly through to week 32. Steroids were then tapered using a defined schedule. The primary efficacy endpoint was the percentage of patients with steroid sparing, defined as discontinuation of steroid therapy without a disease flare (Crohn's Disease Activity Index score > or =220 points) at week 36. RESULTS Steroid sparing occurred in 53 of 181 (29.3%) CDP571 patients and 33 of 90 (36.7%) placebo patients (P = 0.24). Adverse events occurred at similar frequencies in both treatment groups. CONCLUSIONS CDP571 was ineffective for sparing steroids in patients with steroid-dependent Crohn's disease. CDP571 was well tolerated.

Abstract
BACKGROUND The inflammatory bowel disease questionnaire (IBDQ) is a frequently used outcome parameter in clinical trials. Whereas the validity and reproducibility of the IBDQ have been extensively studied, there are limited data on its short-term responsiveness and cutoff values for remission and partial clinical response. METHODS The IBDQ score and its bowel (BD), systemic (SysD), emotional (ED), and social (SocD) dimensions were tested for responsiveness in a cohort of 224 patients with Crohn's disease (CD) treated with infliximab for refractory luminal disease. Changes in the IBDQ score and its dimensions 4 weeks after therapy were analyzed and correlated with changes in the Crohn's Disease Activity Index (CDAI). The responsiveness ratios of the IBDQ and its dimensions were analyzed. Using regression line with DeltaCDAI, the cutoff values for the IBDQ remission and response were calculated. RESULTS Overall, there was a good correlation between the CDAI and IBDQ at week 0 (correlation coefficient, 0.69; P < .001) and week 4 (-0.76; P < .001) and change after 4 weeks (0.74; P < .001). The correlation coefficients for DeltaCDAI and changes in BD, SysD, ED, and SocD were 0.753, 0.552, 0.620, and 0.631, respectively; all P < 0.001. The responsiveness ratios for DeltaIBDQ, BD, SysD, ED, and SocD were 2.6, 2.1, 1.9, 1.7, and 1.9, respectively. Regression line for the IBDQ (r = -0.76, P < .001) resulted in a cutoff value for remission of 168 points and for DeltaIBDQ resulted in a cutoff value of 22 and 27 points for clinical improvement based on DeltaCDAI > or = -70 and > or = -100 points. CONCLUSIONS The IBDQ is a responsive instrument for reflecting quick change in the quality of life of patients with CD. Cutoff values for the IBDQ remission and partial response were 168 and > or = 27 points.

Abstract
The Crohn's disease activity index (CDAI) is the most widely used measure of clinical disease activity in patients entered into clinical trials. The prospective nature of the CDAI calculation precludes its use as a clinical assessment tool. We compared the retrospective evaluation of the CDAI with the prospective evaluation in a heterogeneous patient population of 100 patients with Crohn's disease. The correlation between the two assessment methods was good with an r-value of 0.84 (p < 0,0001). There was a tendency of patients with a high retrospective CDAI to have a lower prospective CDAI which is explained by intention to treat. This study shows that a retrospective assisted evaluation of the CDAI is as accurate as the traditional prospective evaluation.

Abstract
AIM To evaluate CDP571, a humanized monoclonal antibody to tumour necrosis factor-alpha, for the treatment of corticosteroid-dependent Crohn's disease. METHODS Patients with corticosteroid-dependent Crohn's disease (use of prednisolone 15-40 mg/day or budesonide 9 mg/day for at least 8 weeks, a previous failed attempt to discontinue corticosteroids within 8 weeks, and Crohn's Disease Activity Index score 150 points or less) were enrolled in a 16-week, randomized, double-blind, placebo-controlled trial. The patients received intravenous CDP571 (20 mg/kg at week 0 and 10 mg/kg at week 8) or placebo. Corticosteroid therapy was decreased following a predefined schedule. The primary efficacy end-point was the percentage of patients with corticosteroid-sparing [i.e. no disease flare (Crohn's Disease Activity Index score > or =220 points) and no longer requiring corticosteroid therapy] at week 10. The major secondary efficacy end-point was corticosteroid-sparing at week 16. RESULTS Seventy-one patients received treatment. Corticosteroid-sparing was achieved by 19 of 39 (48.7%) CDP571 patients and 13 of 42 (40.6%) placebo patients (P = 0.452) at week 10, and by 18 of 39 (46.2%) CDP571 patients and seven of 32 (21.9%) placebo patients (P = 0.032) at week 16. CDP571 therapy was well-tolerated and the incidence of serious adverse events was similar to placebo. CONCLUSIONS The CDP571 was effective for corticosteroid-sparing at week 16 but not week 10, and was well-tolerated in patients with corticosteroid-dependent Crohn's disease.

Abstract
BACKGROUND/OBJECTIVE The purpose of this study was to compare patient outcomes and quality of life for people with neurogenic bowel using either a standard bowel care program or colostomy. METHODS We analyzed survey data from a national sample, comparing outcomes between veterans with spinal cord injury (SCI) who perform bowel care programs vs individuals with colostomies. This study is part of a larger study to evaluate clinical practice guideline implementation in SCI. The sample included 1,503 veterans with SCI. The response rate was 58.4%. For comparison, we matched the respondents with colostomies to matched controls from the remainder of the survey cohort. A total of 74 veterans with SCI and colostomies were matched with 296 controls, using propensity scores. Seven items were designed to elicit information about the respondent's satisfaction with their bowel care program, whereas 7 other items were designed to measure bowel-related quality of life. RESULTS No statistically significant differences in satisfaction or quality of life were found between the responses from veterans with colostomies and those with traditional bowel care programs. Both respondents with colostomies and those without colostomies indicated that they had received training for their bowel care program, that they experienced relatively few complications, such as falls as a result of their bowel care program, and that their quality of life related to bowel care was generally good. However, large numbers of respondents with colostomies (n = 39; 55.7%) and without colostomies (n = 113; 41.7%) reported that they were very unsatisfied with their bowel care program. CONCLUSION Satisfaction with bowel care is a major problem for veterans with SCI.

Abstract
BACKGROUND Targeting tumour necrosis factor alpha (TNF-alpha) has demonstrated efficacy in Crohn's disease. AIM To evaluate CDP571, a humanised antibody to TNF-alpha, for treating active Crohn's disease. PATIENTS A total of 396 patients with moderate to severe Crohn's disease. METHODS In a 28 week, randomised, double blind, placebo controlled trial, patients received intravenous CDP571 (10 mg/kg) or placebo every eight weeks to week 24. The primary outcome measure was clinical response (a decrease in the Crohn's disease activity index (CDAI) to > or =100 points or remission (CDAI score < or =150 points)) at week 28. A secondary outcome measure was clinical response (using the same definition) at week 2. RESULTS Clinical response occurred at week 28 in 80/263 (30.4%) CDP571 patients and 31/132 (23.5%) placebo patients (p = 0.102). Clinical response at week 2 occurred in 90/263 (34.2%) CDP571 patients and 28/132 (21.2%) placebo patients (p = 0.011). Post hoc exploratory subgroup analysis of 159 patients with baseline C reactive protein (CRP) > or =10 mg/l demonstrated significant differences between CDP571 and placebo in clinical response rates at weeks 2 (CDP571, 50/101 (49.5%); placebo, 9/58 (15.5%); p<0.001) and 28 (CDP571, 29/101 (28.7%); placebo, 7/58 (12.1%); p = 0.018). Adverse events occurred at similar frequencies in both treatment groups. CONCLUSIONS CDP571 is modestly effective for short but not long term treatment of unselected patients with moderate to severe Crohn's disease. The clinical relevance of this short term effect is unclear. Post hoc analysis suggests both short and long term efficacy of CDP571 in patients with elevated baseline CRP (> or =10 mg/l). CDP571 is well tolerated.

Abstract
BACKGROUND The current understanding of quality of life impairment in inflammatory bowel disease has largely been derived from selected populations and may not reflect the experience of patients in the community, where fewer than half are likely to be under specialist care. AIM To describe the health-related quality of life in a community-based sample of patients with established inflammatory bowel disease and explore its association with the type and extent of disease, gender, age, material deprivation and other factors. METHODS Adults with established inflammatory bowel disease were identified systematically from the records of 23 family practices in north-east England. The health-related quality of life was assessed by self-completion of the UK Inflammatory Bowel Disease Questionnaire. RESULTS Five hundred and fifty-six patients were sent the questionnaire and 409 (74%) gave usable replies. Lower scores (worse quality of life) were significantly associated with female gender, Crohn's disease, more extensive disease (ulcerative colitis) and being under specialist care. The mean health-related quality of life score was significantly lower in patients resident in more deprived districts, independent of the type and extent of disease. CONCLUSIONS Most patients with established inflammatory bowel disease showed only minor impairment of their health-related quality of life. On average, women and those with Crohn's disease were relatively more affected. Clinicians responsible for the care of patients with inflammatory bowel disease should be aware of these more vulnerable groups.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GERD) is highly prevalent in Western countries. Because the majority of patients do not present with endoscopic abnormalities, the assessment of the symptom severity and quality of life, and their response to treatment, has become increasingly important. Self-assessed symptom questionnaires are now key instruments in clinical trials. AIM To evaluate the validity of available GERD measurement tools. METHODS An ideal GERD symptom assessment instrument, suitable as a primary end-point for clinical trials, should possess the following characteristics: (i) be sensitive in patients with GERD; (ii) cover the frequency and intensity of typical and atypical GERD symptoms; (iii) be multidimensional (cover all symptom dimensions); (iv) have proven psychometric properties (validity, reliability and responsiveness); (v) be practical and economical; (vi) be self-assessed; (vii) use 'word pictures' which are easy to understand for patients; (viii) respond rapidly to changes (responsiveness over short time intervals); (ix) be used daily to assess changes during and after therapy; and (x) be valid in different languages for international use. RESULTS A literature review revealed five scales that met some of the above characteristics, but did not fulfil all criteria. CONCLUSION There is a need for a new evaluative tool for the assessment of GERD symptoms and their response to therapy.

Abstract
OBJECTIVES The Inflammatory Bowel Disease Questionnaire (IBDQ) is a disease-specific questionnaire for assessing health-related quality of life. The main objective of this study is to assess three main areas of the validation of the Greek IBDQ: internal validity, designating items to dimensions, and selecting items for a short form. An additional aim is to present alternative validation methods for improved and robust results. METHODS A total of 134 patients with IBD, including 74 with ulcerative colitis (UC) and 60 with Crohn's disease (CD), completed the Greek IBDQ. Internal validity was assessed by using standard methods and multiple correlation analysis. Factor analysis of the 32 items of the questionnaire was carried out to identify the underlying dimensions, using principal factor analysis and maximal likelihood. For selecting items for a short form, three methods of linear regression analysis were used. RESULTS All items had adequate convergent validity (except item 11 in the CD group) and acceptable discriminant validity (except item 11 for both groups). Factor analysis yielded five factors (emotional function, social function, systemic symptoms, bowel symptoms, and abdominal symptoms). The combination of three regression techniques and their internal validity yielded two similar but distinct short forms, one for UC and one for CD. Both forms had high correlation with the total IBDQ score (R(2) = 0.949 and 0.977, respectively). CONCLUSIONS The Greek IBDQ had good internal validity. The original designation in four dimensions and the original short form could be improved with only slight modifications.

Abstract
BACKGROUND Health-related quality of life is an important outcome measure in inflammatory bowel disease. The Inflammatory Bowel Disease Questionnaire is a quality of life questionnaire that has not been validated previously in Chinese patients with inflammatory bowel disease. AIM To develop and validate a Chinese translation of the Inflammatory Bowel Disease Questionnaire, specifically determining its construct validity, discriminant ability, reliability and sensitivity to change. METHODS We developed a Chinese version of the Inflammatory Bowel Disease Questionnaire. Chinese patients with Crohn's disease and ulcerative colitis completed the Chinese Inflammatory Bowel Disease Questionnaire and visual analogue scales measuring systemic, social, bowel and emotional well-being. Patients also completed a validated Chinese SF-36 generic quality of life questionnaire, the Crohn's disease activity index or the clinical activity index for ulcerative colitis. RESULTS One hundred and thirty-five patients (59 with Crohn's disease and 76 with ulcerative colitis) were enrolled, 99 of whom also completed the Chinese Inflammatory Bowel Disease Questionnaire for a second time. The Chinese Inflammatory Bowel Disease Questionnaire correlated well with the SF-36 for all four domains (Spearman: r = 0.55-0.80), the Crohn's disease activity index (r = -0.62-0.72) and the clinical activity index for ulcerative colitis (r = -0.44-0.68), as well as with the visual analogue scales. The Chinese Inflammatory Bowel Disease Questionnaire accurately distinguished between active and inactive disease. Test-re-test reliability showed excellent intra-class correlation (0.76-0.92; all P < 0.001). The Chinese Inflammatory Bowel Disease Questionnaire was also sensitive to changes in disease activity (P < 0.05). CONCLUSION The Chinese Inflammatory Bowel Disease Questionnaire is a valid and reliable test that correlates well with the patients' subjective well-being and clinical disease activity.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) have identified a need for more information about their disease. PURPOSE To assess the effect of an educational intervention on health-related quality of life (HRQOL) in patients with IBD. METHODS Consecutive ambulatory IBD patients were randomized to receive four IBD-specific educational booklets or usual care. Subjects completed two disease-specific HRQOL questionnaires-the Inflammatory Bowel Disease Questionnaire (IBDQ) (range 1-poor to 7-excellent) and the Quality Index in Crohn's and Colitis (QuICC) (range 1-excellent to 5-poor) at entry and after 2 weeks. The mean change in HRQOL scores at follow-up was compared between the education and control groups. RESULTS 59 subjects participated, with a mean age of 40.0 +/- 11.9 years. 34 were given educational booklets and 25 received standard care. 6 patients (10%) did not complete the study. Mean IBDQ scores became significantly worse in the education group with a change of -0.17 +/- 0.49 compared with controls at +0.28 +/- 0.62 (p = 0.006). This could be explained by worsened disease activity in the education group. There was no significant change in the QuICC scores (p = 0.61). Education group patients who had not received prior educational material had improved mean IBDQ scores of +0.24 +/- 0.47 compared with education patients who had received educational material prior to this study, with a score change of -0.25 +/- 0.46 (p = 0.09). CONCLUSIONS The addition of educational booklets to IBD patients in a tertiary center does not improve, and may worsen, short-term HRQOL. Education of newly diagnosed or less informed patients should be studied further.

Abstract
BACKGROUND Infusion of anti-tumour necrosis factor-alpha appears to be highly effective in patients with Crohn's disease. AIM To assess the effect of infliximab on the quality of life in patients with active or fistulizing disease, as measured by the inflammatory bowel disease questionnaire, and to examine the impact on its four dimensions. METHODS An observational study was conducted in 65 patients. An infusion of 5 mg/kg infliximab was given at week 0 in patients with active disease and at week 0, 2 and 6 in fistulizing disease. Changes from baseline in the total and dimensional inflammatory bowel disease questionnaire scores were calculated and compared between the patient groups. Potential predictors of change in the quality of life were identified. RESULTS In the active disease group, at week 4, the mean total and dimensional inflammatory bowel disease questionnaire scores improved compared to baseline (P < 0.001). In the fistulizing group, at week 6, all scores changed from baseline (P < 0.05). Improvement in the total inflammatory bowel disease questionnaire score correlated well with the improvement of the Crohn's disease activity index. Systemic and social scores improved more than bowel and emotional scores. Inflammatory Crohn's disease and a young age at diagnosis were predictors for a better response to infliximab therapy. CONCLUSIONS Infliximab therapy improves all dimensions of the quality of life in patients with Crohn's disease.

Abstract
BACKGROUND Health Related Quality of Life (HRQoL) is an important outcome measure in Inflammatory Bowel Disease (IBD). The aim of our study was to assess HRQoL in a population of 135 Greek patients with IBD. METHODS A cohort of 135 patients with IBD, 81 with ulcerative colitis (UC) and 54 with Crohn's disease (CD) were enrolled in our study. Demographic and disease-related data were recorded. HRQoL was assessed by a disease-specific and a generic questionnaire, IBDQ and SF-36, respectively. Disease activity was assessed by Harvey-Bradshaw Index and the Colitis Activity Index for CD and UC patients, respectively. RESULTS Among all variables recorded in our study, only disease activity had a significant effect on HRQoL. Patients with active disease scored significantly lower on both IBDQ and SF-36 when compared to those in remission. Only two among the four IBDQ dimensions, bowel and systemic, had significant ability in distinguishing best patients in remission from those with active disease. CONCLUSIONS IBD has a negative impact on HRQoL. Patients with active disease are more impaired than patients in remission. In our population of patients bowel and systemic dimensions had a predominant value in patients' perception of quality of life. Patients in our study using the same instrument scored higher than previously reported.

Abstract
OBJECTIVE The Short Inflammatory Bowel Disease Questionnaire (SIBDQ) is a health-related quality of life (HRQoL) tool measuring physical, social, and emotional status (score 10-70, poor to good HRQoL). The SIBDQ has been predominantly used in trials for Crohn's disease, and further validation of the SIBDQ is desirable in ulcerative colitis (UC) patients. The primary objective was to further validate the SIBDQ by examining discriminant ability against measures of disease activity. The secondary objectives were to examine reliability and responsiveness to change. METHODS UC patients attending hospital completed the SIBDQ and two activity indices. Patients' disease status (remission, mild, moderate, or severe relapse) was determined subjectively by the patients and their physician. RESULTS Scores were obtained for 69 events in 61 patients. mean age 47.8 yr (range 16-79). All classes of disease extent were represented. The mean SIBDQ score was 48.4 (13-70). The difference between mean score in patients in remission and relapse was -20.1 (95% CI = -25.1 to -15.1). The difference for remission and mild relapse was -14.6 (95% CI = -8.9 to -20.2). The correlation between SIBDQ and the activity indices were good, r = -0.83 and r = -0.61. Eight patients presented twice. Those with unchanged disease status showed no significant difference in the mean SIBDQ score. Patients whose disease status had deteriorated from remission to mild relapse, or from mild to moderate relapse demonstrated a mean reduction of 11.8 points (95% CI = 20.1-3.4). CONCLUSIONS This study contributes to the validation of the SIBDQ as a HRQoL tool in UC. It is reproducible and responsive to changes in disease activity.

Abstract
BACKGROUND Urinary and fecal incontinence in females are both common and distressing conditions. Because common pathophysiologic mechanisms have been described, an association between the two would be expected. The aim of this study was to determine whether patients with lower urinary tract dysfunction have concomitant fecal incontinence when compared with age and gender matched community controls and, second, to determine whether they have predisposing factors that have led to lower urinary tract symptoms and concomitant fecal incontinence. METHODS A case-control study was performed by means of detailed questionnaire and review of investigation results. One thousand consecutive females presenting for urodynamic investigation of lower urinary tract dysfunction, were compared with 148 age and gender matched community controls. RESULTS Frequent fecal incontinence was significantly more prevalent among all cases than among community controls (5 vs. 0.72 percent, P = 0.023). Occasional fecal incontinence was also more prevalent (24.6 vs. 8.4 percent, P < 0.001). Fecal incontinence was not significantly more prevalent among females with genuine stress incontinence (5.1 percent) when compared with females with detrusor instability (3.8 percent) or any other urodynamic diagnosis. Symptoms of fecal urgency and fecal urge incontinence were significantly more prevalent among those with a urodynamic diagnosis of detrusor instability or sensory urgency than among females with other urodynamic diagnoses or community controls. Multivariate analysis comparing cases with fecal incontinence with other cases and also with community controls did not indicate that individual obstetric factors contributed significantly to the occurrence of fecal incontinence in these patients. CONCLUSIONS There is an association between genuine stress incontinence, lower urinary tract dysfunction, and symptoms of fecal incontinence, but the exact mechanism of injury related to childbirth trauma is questioned.

Abstract
BACKGROUND Any disease and its treatment has an important impact on health-related quality of life for affected individuals. There have been few previous studies on the quality of life for children with inflammatory bowel disease (IBD). METHODS A cross-cultural comparison was performed to determine whether the concerns of children with IBD in the United Kingdom are ranked similarly to those of children with IBD in Canada. An item reduction questionnaire, developed from interviews with Canadian children with IBD, was scored by 53 British children with IBD for importance and frequency, as a questionnaire had been scored previously by 117 Canadian children. RESULTS There was a significant correlation between the mean scores (r = 0.831, P < 0.001) and ranks (r = 0.801, P < 0.001) for the 96 questions, and 43 of the 50 highest-ranking concerns corresponded for both populations. Confidence interval analysis showed a significant difference between the mean values for 21 of the 96 items; 20 of these 21 were ranked higher in the United Kingdom than they had been in Canada, suggesting that the frequency and/or degree of concern was greater for the British children with IBD. CONCLUSIONS Health-related concerns of British children with Crohn disease and ulcerative colitis correlate closely with those of Canadian children with those diseases. Further studies are needed to determine the sensitivity of individual questions, the most appropriate wording of these questions, and the optimal length for a proposed instrument to assess quality of life in children with IBD.

Abstract
Patient-rated symptom and health-related quality-of-life (HR-QOL) outcomes are important end-points for clinical trials of medical treatments for gastrointestinal (GI) disorders. Based on this review, patient outcomes research is focused on gastroesophageal reflux disease and dyspepsia, with a growing interest in irritable bowel syndrome but little research in gastroparesis. State-of-the-art for patient-rated symptom scales is rudimentary with an abundance of scales and little attention to systematic instrument development or comprehensive psychometric evaluation. Generally, disease-specific HR-QOL measures have been more systematically developed and evaluated psychometrically, but few have been incorporated into clinical trials. More comprehensive outcome assessments are needed to determine the effectiveness of new medical treatments for functional GI disorders. Future clinical trials of GI disorders should combine clinician assessments of outcomes and symptoms with patient-rated symptom and HR-QOL end-points.

Abstract
BACKGROUND Health-Related Quality of Life is an important measure of illness perception on the part of the patient. In this review, the current status of the Health-Related Quality of Life assessment in studies concerning inflammatory bowel disease is examined and the various instruments proposed for this purpose are considered and compared. METHODS A search was made of the Medline database, for relevant articles since 1980. Standard criteria were used for including studies for further evaluation. RESULTS All studies on measuring Health-Related Quality of Life in inflammatory bowel disease patients conclude that the instruments used were valid and reliable assessment tools. Valid instruments that have been proposed for the assessment of health-related quality of life are: the Inflammatory Bowel Disease Questionnaire, the Rating Form of Inflammatory Bowel Disease Patient Concerns, an Inflammatory Bowel Disease-specific questionnaire developed in Cleveland, the Ulcerative colitis and Crohn's disease Health Status Scales and a Disease-specific questionnaire developed in the University of Padova. CONCLUSIONS Assessing health-related quality of life in inflammatory bowel disease patients is an ever-expanding practice, especially in clinical trials. The instruments that, currently, satisfy most demands for simplicity and validity are the Inflammatory Bowel Disease Questionnaire, reflecting primarily disease activity, and the Rating Form of Inflammatory Bowel Disease Patient Concerns which corresponds more to the psychological and social aspects of inflammatory bowel disease from the patient's point of view.

Abstract
Our aims were to assess the impact on health-related quality of life (HRQOL) of a controlled ileal release (CIR) formulation of budesonide in active Crohn's disease (CD) and further define the role of HRQOL, using the Inflammatory Bowel Disease Questionnaire (IBDQ), in assessing outcome in CD. A randomized trial was conducted in 258 patients with active ileal or ileocecal CD. Budesonide CIR 1.5 mg, 4.5 mg, 7.5 mg, or placebo was given b.i.d. for 8 weeks. IBDQ score changes were compared among groups. Correlations for IBDQ and Crohn's Disease Activity Index (CDAI) scores were calculated. Mean IBDQ scores improved significantly over placebo by 2 weeks in budesonide 15 mg (155+/-38; p = 0.006) and 9 mg groups (157+/-33; p = 0.0002). Bowel, systemic, social, and emotional subscores were also significantly better (p < 0.002) at 2 and 8 weeks in the 9 mg group. Improved HRQOL scores correlated well with decreased CDAI (-0.8 < r < -0.4). Average per item change in IBDQ at remission was 1.17 to 1.48. Prior surgery (p < 0.005) or current smoker (p < 0.05) status predicted poorer initial HRQOL but not response. Budesonide CIR 9 or 15 mg/day rapidly and significantly improved HRQOL in active CD.

Abstract
Measurement of health-related quality of life (HRQL) is becoming more important in studies of patients with inflammatory bowel disease. The McMaster IBDQ is the most widely used HRQL instrument for these patients. However, its use with patients in the United Kingdom has not been validated. This study develops and validates a UK version of the McMaster IBDQ (UK IBDQ). The UK IBDQ was tested with two samples of patients for its reliability, validity, reproducibility, and responsiveness. The first sample consisted of 180 patients participating in a randomized clinical trial. The second was recruited from members of the National Association for Colitis and Crohns Disease. Reliability of the subscales and the summary score of the UK IBDQ is demonstrated by Cronbach's alpha and item-total correlations. Their validity is demonstrated by their correlations with SF-36 subscales and an empirical index of disease activity. Good intraclass correlations and responsiveness ratios show their reproducibility and responsiveness. The findings support the reliability, validity, reproducibility, and responsiveness of the UK IBDQ and its acceptability to patients in UK.

Abstract
We have audited the quality of life and functional outcome from restorative proctocolectomy and ileoanal pouch surgery in patients with familial adenomatous polyposis coli (FAP). By assessing the effect on employment, leisure activity, social life, and sexual function using a questionnaire derived from a modified McMaster Inflammatory Disease Questionnaire we have assessed the functional outcome of the pouch [ 1]. We have shown that although quality of life is maintained from the results of the questionnaire, over 50% of the patients felt that the pouch had not improved their lives. It has been shown that colitic patients have less complete function than polyposis patients, although the former were more satisfied with the results of their surgery [ 2]. Perhaps then the realization of the nature of FAP is not an incentive to surgery, when your life is to be ruled by your bowels. Therefore perhaps we should consider the outcomes in patients with FAP to be different from those in patients who have lived with colitis.

Abstract
BACKGROUND Health-related quality of life (HRQOL) describes the physical, social, and emotional attitudes and behavior of people in relation to health status. By the 1980s, HRQOL was noted to be impaired in chronic diseases but inflammatory bowel disease, had not been extensively described. METHODS This review summarizes the results of several studies describing the development and application of a disease-specific HRQOL instrument, the Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS An initial study described how patients with inflammatory bowel disease identified 150 problems they had experienced in four domains: bowel, systemic, emotional, and social function. Almost half of patients underreported impairment until encouraged by a reminder list. Thirty-two questions were included in the final questionnaire and were scored on a 7-point scale from I (worst) to 7 (best) for a range of possible scores from 32 to 224. Physicians' and spouses' global assessments correlated poorly with patient-reported HRQOL. Subsequent validation of the IBDQ suggested a strong correlation with disease severity (r = -0.5; p < 0.001) and a test-retest reliability of 0.7. Mean score changes of 16 to 30 points have been linked to changes in therapy. Statistically significant differences also occur between active and inactive disease. Results of four clinical trials have included the IBDQ as a measure of outcome. A self-administered version and a shortened version of the IBDQ have also been validated. CONCLUSIONS The IBDQ is a valid, reliable, and sensitive measure that can be meaningfully applied in clinical trials. The short IBDQ may also be useful in clinical research and office practice.
