RESUMO
Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, showed a wide spectrum of intestinal and extra-intestinal manifestations, which rendered the patients physically inactive and impaired their quality of life. It has been found that physical activity is a non-pharmacological intervention that improves the quality of life for those patients. Irisin is one member of the myokines secreted by muscle contraction during exercise and could be used as an anti-inflammatory biomarker in assessing the physical activity of IBD patients. In addition, experimental studies showed that exogenous irisin significantly decreased the inflammatory markers and the histological changes of the intestinal mucosa observed in experimental colitis. Furthermore, irisin produces changes in the diversity of the microbiota. Therefore, endogenous or exogenous irisin, via its anti-inflammatory effects, will improve the health of IBD patients and will limit the barriers to physical activity in patients with IBD.

Ulcerative colitis (UC) is a serious inflammatory bowel disease (IBD) with high morbidity and mortality worldwide. As the traditional diagnostic techniques have various limitations in the practice and diagnosis of early ulcerative colitis, it is necessary to develop new diagnostic models from molecular biology to supplement the existing methods. In this study, we developed a machine learning-based synthesis to construct an artificial intelligence diagnostic model for ulcerative colitis, and the correctness of the model is verified using an external independent dataset. According to the significantly expressed genes related to the occurrence of UC in the model, an unsupervised quantitative ulcerative colitis related score (UCRScore) based on principal coordinate analysis was established. The UCRScore is not only highly generalizable across UC bulk cohorts at different stages, but also highly generalizable across single-cell datasets, with the same effect in terms of cell numbers, activation pathways and mechanisms. As an important role of screening genes in disease occurrence, based on connectivity map analysis, 5 potential targeting molecular compounds were identified, which can be used as an additional supplement to the therapeutic of UC. Overall, this study provides a potential tool for differential diagnosis and assessment of bio-pathological changes in UC at the macroscopic level, providing an opportunity to optimize the diagnosis and treatment of UC.

BACKGROUND AND AIMS: Most paediatric inflammatory bowel disease [IBD] studies are performed after medications are approved in adults, and the majority of participants in these studies are adolescents. We hypothesised that adolescent-onset IBD is not fundamentally different from adult-onset IBD. If this is correct, the value of delaying access to novel drugs in adolescents becomes questioned. METHODS: Data from 11 randomised, double-blind, placebo-controlled, adult Phases 2 and 3 trials of four biologics were analysed. Participants were categorised as having adolescent- or adult-onset disease [diagnosed 12 toâ <18, orâ ≥18 years]. Multivariable modelling explored the association between age at diagnosis and response to treatment, after adjustment for disease duration, extent, and severity at baseline. Data from dose arms were pooled to evaluate similarity of therapeutic response between adolescent- and adult-onset IBD within the same trial [not between doses or across trials]. Ratios of odds ratios [ORs] between the two groups were evaluated. RESULTS: Data from 6283 study participants (2575 with Crohn's disease [CD], 3708 with ulcerative colitis [UC]) were evaluated. Of 2575 study participants with CD, 325 were 12-<18 years old at diagnosis; 836 participants [32.4%] received placebo. Of 3708 participants with UC, 221 were 12-<18 years old at diagnosis; 1212 [33%] were receiving placebo. The majority of the ratios of ORs were within 2-fold, suggesting that responses in adolescent- and adult-onset participants are generally similar. CONCLUSION: Data presented lend support for extrapolating efficacy of biologics from adults to adolescents with IBD, which would facilitate earlier labelling and patient access.

BACKGROUND AND AIMS: Current endoscopic scoring systems for ulcerative colitis (UC) do not consider the extent of mucosal inflammation. The modified Mayo endoscopic score (MMES) was developed to detect segmental endoscopic improvement. We evaluated the ability of the MMES to predict long-term clinical outcomes and compared it to the widely used Mayo endoscopic subscore (MES). METHODS: Consecutive patients with moderate to severe UC starting biological therapy were enrolled between January 2014 and September 2017 in this prospective observational study. A clinical and endoscopic evaluation was performed at baseline and at week 8/14. A modified Mayo score was used to grade clinical activity, MES and MMES were used to evaluate endoscopic activity. Patients were divided into 3 groups according to the evolution of endoscopic activity, namely endoscopic improvement (MES ≤ 1), segmental endoscopic response only (MES > 1, but decrease in MMES ≥ 30%) or no endoscopic response (all others). Over the follow-up period clinical relapse-, discontinuation- and colectomy-free survival were assessed. RESULTS: A total of 150 patients were included (48% female, median age 42 years, median disease duration 7 years) with a median follow-up of 61 months. We identified 69 patients with endoscopic improvement, 27 with segmental endoscopic response and 54 without endoscopic response. Patients with segmental endoscopic response showed intermediate long-term clinical outcomes as compared to the other two groups (log rank p = 0.003 for clinical relapse-, and p < 0.001 for both discontinuation- and colectomy-free survival). CONCLUSIONS: The MMES exhibited a benefit in predicting long-term outcome in UC even though endoscopic improvement remains the strongest predictor.

BACKGROUND AND AIMS: Epidemiologic evidence suggests that Hodgkin lymphoma (HL) and multiple sclerosis (MS) share a common set of risk factors with Crohn's disease (CD) and ulcerative colitis (UC). It was hypothesized that such shared risk factors would lead to clustering of the 4 diagnoses in the same patients. METHODS: All patients with HL, MS, CD, or UC were identified in the veterans population from 2016-2020 and the Medicare population from 1986 to 1989. In a case-control study, the observed concurrences amongst these 4 diagnoses were compared with their expected frequencies in the overall veterans or Medicare population during the same time period by calculating odds ratios (OR) with their 95% confidence intervals (CI). RESULTS: The study included 6 million veterans and 35 million Medicare patients. In the veterans population, inflammatory bowel disease (IBD) was significantly associated with a concurrent diagnosis of HL (OR: 1.40, 95% CI: 1.15-1.71) and MS (1.34, 1.19-1.50). In the Medicare population, IBD was also significantly associated with HL (1.84, 1.07-3.17) and MS (2.31, 1.59-3.35). Similar trends were observed in CD or UC when analyzed separately in both datasets. In the veterans population, adjustment for the potentially confounding influence of ethnicity, sex, and age left all OR values largely unaffected and statistically significant. CONCLUSION: The concurrence of IBD with HL or MS could reflect on a common pathway in the etiology or pathogenesis of these 4 diseases.

BACKGROUND: Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease of the digestive tract with increasing prevalence globally. Although venous thromboembolism (VTE) is a major complication in IBD patients, it is often underappreciated with limited tools for risk stratification. AIM: To estimate the proportion of VTE among IBD patients and assess genetic risk factors (monogenic and polygenic) for VTE. METHODS: Incident VTE was followed for 8465 IBD patients in the UK Biobank (UKB). The associations of VTE with F5 factor V leiden (FVL) mutation, F2 G20210A prothrombin gene mutation (PGM), and polygenic score (PGS003332) were tested using Cox hazards regression analysis, adjusting for age at IBD diagnosis, gender, and genetic background (top 10 principal components). The performance of genetic risk factors for discriminating VTE diagnosis was estimated using the area under the receiver operating characteristic curve (AUC). RESULTS: The overall proportion of incident VTE was 4.70% in IBD patients and was similar for CD (4.46%), UC (4.49%), and unclassified (6.42%), and comparable to that of cancer patients (4.66%) who are well-known at increased risk for VTE. Mutation carriers of F5/F2 had a significantly increased risk for VTE compared to non-mutation carriers, hazard ratio (HR) was 1.94, 95% confidence interval (CI): 1.42-2.65. In contrast, patients with the top PGS decile had a considerably higher risk for VTE compared to those with intermediate scores (middle 8 deciles), HR was 2.06 (95%CI: 1.57-2.71). The AUC for differentiating VTE diagnosis was 0.64 (95%CI: 0.61-0.67), 0.68 (95%CI: 0.66-0.71), and 0.69 (95%CI: 0.66-0.71), respectively, for F5/F2 mutation carriers, PGS, and combined. CONCLUSION: Similar to cancer patients, VTE complications are common in IBD patients. PGS provides more informative risk information than F5/F2 mutations (FVL and PGM) for personalized thromboprophylaxis.

Many molecular targeted agents, including biologics, have emerged for inflammatory bowel diseases (IBD), but their high prices have prevented their widespread use. This study aimed to reveal the changes in patient characteristics and the therapeutic strategies of IBD before and after the implementation of biologics in Japan, where the unique health insurance system allows patients with IBD and physicians to select drugs with minimum patient expenses. The analysis was performed using a prospective cohort, including IBD expert and nonexpert hospitals in Japan. In this study, patients were classified into two groups according to the year of diagnosis based on infliximab implementation as the prebiologic and biologic era groups. The characteristics of therapeutic strategies in both groups were evaluated using association analysis. This study analyzed 542 ulcerative colitis (UC) and 186 Crohn's disease (CD). The biologic era included 53.3% of patients with UC and 76.2% with CD, respectively. The age of UC (33.9 years vs. 38.8 years, P < 0.001) or CD diagnosis (24.3 years vs. 31.9 years, P < 0.001) was significantly higher in the biologic era group. The association analysis of patients with multiple drug usage histories revealed that patients in the prebiologic era group selected anti-tumor necrosis factor (TNF)-α agents, whereas those in the biologic era group preferred biologic agents with different mechanisms other than anti-TNF-α. In conclusion, this study demonstrated that both patient characteristics and treatment preferences in IBD have changed before and after biologic implementation.

BACKGROUND: Inflammatory bowel disease has been linked to increasing healthcare costs, but longitudinal data on other societal costs are scarce. AIM: To assess costs, including productivity losses, in patients with prevalent Crohn's disease (CD) or ulcerative colitis (UC) in Sweden between 2007 and 2020. METHODS: We linked data from national registers on all patients with CD or UC and a matched (sex, birthyear, healthcare region and education) reference population. We assessed mean costs/year in Euros, inflation-adjusted to 2020, for hospitalisations, out-patient visits, medications, sick leave and disability pension. We defined excess costs as the mean difference between patients and matched comparators. RESULTS: Between 2007 and 2020, absolute mean annual societal costs in working-age (18-64 years) individuals decreased by 17% in CD (-24% in the comparators) and by 20% in UC (-27% in comparators), due to decreasing costs from sick leave and disability, a consequence of stricter sick leave regulations. Excess costs in 2007 were dominated by productivity losses. In 2020, excess costs were mostly healthcare costs. Absolute and excess costs increased in paediatric and elderly patients. Overall, costs for TNF inhibitors/targeted therapies increased by 274% in CD and 638% in UC, and the proportion treated increased from 5% to 26% in CD, and from 1% to 10% in UC. CONCLUSION: Between 2007 and 2020, excess costs shifted from productivity losses to direct healthcare costs; that is, the patients' compensation for sickness absence decreased, while society increased its spending on medications. Medication costs were driven both by expanding use of TNF inhibitors and by high costs for newer targeted therapies.

BACKGROUNDS AND AIMS: Absence of neutrophils is the minimum standard to consider histological remission of ulcerative colitis [UC]. The PICaSSO Histological Remission Index [PHRI] is a new simple index for UC, based only on the detection of neutrophils. We evaluate PHRI's correlation with endoscopy and its prognostic value compared with other established indices. METHODS: Consecutive patients with UC underwent colonoscopy at two referral centres [Birmingham, UK, and Milan, Italy,] and were followed up for 2 years. Correlation between histology (PHRI, Nancy [NHI], and Robarts [RHI] indexes) and endoscopy (Mayo Endoscopic Score [MES], Ulcerative Colitis Endoscopic Index of Severity [UCEIS], and PICaSSO index) was calculated as Spearman coefficients. Diagnostic performance of endoscopy was assessed with receiver operating characteristic [ROC] curves and outcome stratification with Kaplan-Meier curves. RESULTS: A total of 192 patients with UC was enrolled, representing all grades of endoscopic severity. Correlation between histology and endoscopy did not differ significantly when using PHRI instead of NHI or RHI. In particular, PHRI's correlation with MES, UCEIS, and PICaSSO was 0.745, 0.718, and 0.694, respectively. Endoscopically-assessed remission reflected the absence of neutrophils [PHRIâ =â 0] with areas under the ROC curve of 0.905, 0.906, and 0.877 for MES, UCEIS, and PICaSSO, respectively. The hazard ratio for disease flare between patients in histological activity/remission was statistically similar [pâ >0.05] across indexes [2.752, 2.706, and 2.871 for RHI, NHI, and PHRI, respectively]. CONCLUSION: PHRI correlates with endoscopy and stratifies risk of relapse similarly to RHI and NHI. Neutrophil-only assessment of UC is a simple yet viable alternative to established histological scores.

Inflammatory bowel disease (IBD) pathogenesis is thought to be induced by a mix of genetic susceptibility, microbial populations, and immune triggers such as infections. Severe acute respiratory syndrome coronavirus 2 (SARS-nCoV2) may have increased capacity to generate autoimmune disease as evidenced by known spikes in diseases such as type 1 diabetes mellitus. Public health interventions like masking and closures additionally created remarkable drops in typical viral infections, with remarkable shifts in influenza-like illness reporting in 2020. This study aims to evaluate the impact of SARS-nCoV2 and associated interventions on pediatric IBD presentation in New York City using records of new diagnoses at a consortium of 4 institutions between 2016 and June 2022. We fit time series model (autoregressive integrated moving average model) to monthly and quarterly number of cases of each disease for January 2016-March 2020 and forecast the period between April 2020 and June 2022. We note no decrease in ulcerative colitis (UC) or Crohn disease (CD) in the aftermath of historic low levels of overall viral illness, and statistically significant increases in CD diagnoses and elevation in UC diagnoses creating a trend suggesting overall increase in IBD diagnoses exceeding the baseline rate of increase. These data suggest a possible linkage between SARS-nCoV2 infection rates and subsequent pediatric IBD presentation.

BACKGROUND: Mucosal healing (MH) was proposed to be an ideal treatment goal for patients with inflammatory bowel disease (IBD). Instead of endoscopy to confirm MH, biomarkers are frequently used and have become an indispensable modality for the clinical examination of patients with IBD. SUMMARY: Common biomarkers of IBD include C-reactive protein (CRP), erythrocyte sedimentation rate, antineutrophil cytoplasmic antibodies, anti-Saccharomyces cerevisiae antibodies, leucine-rich α2 glycoprotein, fecal calprotectin (FCP), and the fecal immunochemical test. Biomarkers play five major roles in the management of IBD: (1) diagnosing and distinguishing between IBD and non-IBD or ulcerative colitis and Crohn's disease; (2) predicting treatment response, especially before administrating biologics; (3) monitoring and grasping endoscopic or histological disease activity; (4) replacing endoscopy for diagnosing MH, including endoscopic and histological remission; and (5) predicting recurrence before disease activity appears through symptoms. Many reports have demonstrated the usefulness of CRP and FCP for those five roles; however, they have limitations for diagnosing MH or predicting treatment response. In general, FCP has better ability in those positions than CRP; additionally, leucine-rich α2 glycoprotein can diagnose endoscopic disease activity better than CRP. The novel biomarker, prostaglandin E-major urinary metabolite, and anti-αvß6 antibody are expected to be noninvasive and reliable biomarkers; however, more evidence is required for future studies. Oncostatin M and microRNA are also prospects, in addition to other familiar and novel biomarkers. KEY MESSAGES: Each biomarker has a useful feature; therefore, we should consider their features and use appropriate biomarkers for the five roles to enable noninvasive and smooth management of IBD.

BACKGROUND: Few data describing pre-diagnosis changes in patients with inflammatory bowel disease (IBD) exist. We aimed to determine if there is a pattern of change in use of health resources, medications and laboratory results in the years preceding diagnosis. METHODS: This retrospective study used electronic medical records of Maccabi Health Services (MHS). Patients with IBD ≥ 16 years of age and minimum of 5-years follow-up were identified by entry into the MHS IBD registry and included in the analysis. Demographic, clinical, medication and laboratory data were collected. Generalized estimating equation model was applied to study trends and compare between years. RESULTS: This study included 5643 patients with IBD. Of these, 3039 (53.8%) had Crohn's disease (CD), 2322 (41.1%) had ulcerative colitis (UC) and 282 (5%) had indeterminate colitis (IC). Laboratory parameters including white blood cells, platelets and C-reactive protein showed significant increases while haemoglobin and mean cell volume showed significant decreases in mean values in the 2 years prior to diagnosis with stable values prior to that (p < 0.0001). Parameters such as creatinine, total protein and albumin showed significant, progressive decreases in mean values starting 5 years prior to diagnosis (p < 0.0001). Patients with CD had distinct laboratory trends when compared with patients with UC. CONCLUSIONS: Changes in laboratory parameters, healthcare service and medication use occur during the 5-year period before IBD diagnosis. These data can have future clinical applicability by developing a composite score and referral algorithm introducing red flags into primary care visits and appropriate referral for specialist care.

BACKGROUND AND AIMS: The number of population-based studies in ulcerative colitis [UC] from Eastern Europe is limited. Our aim here was to analyse the incidence, prevalence, disease phenotype, treatment strategy, disease course and colectomy rates in a prospective population-based inception cohort including UC patients diagnosed between 2007 and 2018. The present study is a continuation of the Veszprem IBD cohort since 1977. METHODS: In total, 467 UC patients were included [male/female: 236/231; median age at diagnosis: 36 years, IQR: 25-54 years]. Both in-hospital and outpatient records were collected and comprehensively reviewed. The mean length of follow-up was 8.34â ±â 3.6 years. Demographic data were derived from the Hungarian Central Statistical Office. RESULTS: The mean incidence rate was 11.02/105 person-years in this 12-year period. Prevalence was 317.79/105 persons in 2015. Disease extent at diagnosis was proctitis [E1] in 22.3%, left-sided colitis [E2] in 43.9% and extensive colitis [E3] in 33.8%. The probability of disease extent progression was 11.6% [SE: 1.8] after 5 years. The distribution of maximal therapeutic steps was 5-ASA in 46.9%, corticosteroids in 16.3%, immunosuppressives in 19.3% and biologicals in 16.5%. The probability of receiving biological therapy after diagnosis was 9.9% [SE: 1.4] at 3 years. The overall colectomy rate was 4.1% in the population. The probability of colectomy was 1.5% [SE: 0.6] at 1 year, 3.6% [SE: 0.9] at 5 years and 4.4% [SE: 1.0] at 10 years. CONCLUSIONS: The incidence of UC was high in Hungary, similar to high-incidence areas in Western Europe. Treatment strategies are in line with the biological era. The probability of progressing to proximal disease, and the medium- and long-term colectomy rates were both lower compared with data from Western European centres.

BACKGROUND: Although validated patient-reported outcome (PRO) measurements can categorize patients with inflammatory bowel disease (IBD) into clinical remission or active disease, patients may have different definitions of remission. The purpose of this study was to compare patient-defined remission to remission based on PRO measures and physician global assessment (PGA) and to understand the clinical and demographic factors associated with disagreements. METHODS: We retrospectively analyzed 3257 de-identified surveys from 2004 IBD patients who consented to participate in the Crohn's and Colitis Foundation's IBD Qorus Learning Health System between September 2019 and February 2021. We used logistic regression models with generalized estimating equations to analyze the clinical and demographic factors (eg, age, disease duration, health confidence) associated with discordance between patient-defined remission (yes/no) and PRO-defined remission for ulcerative colitis (UC; PRO2: stool frequency, rectal bleeding) and Crohn's disease (CD; PRO-3: average number of liquid stools, abdominal pain, well-being). RESULTS: Among patients with UC, overall concordance was 79% between patient self-report and PRO2-defined remission and 49% between patient self-report and PGA-defined remission. Among patients with CD, overall concordance was 69% between patient self-report and PRO3-defined remission and 54% between patient self-report and PGA-defined remission. Patients in PRO-defined remission were more likely to report active disease if they had IBDâ <5 years and low health confidence. Patients with PRO-defined active disease were more likely to report remission if they were not using prednisone and had high health confidence. CONCLUSION: Discordance exists between how remission is defined by patients, PRO measures, and PGA.
Discordance between patients' self-reported remission and remission defined based on patient-reported outcomes was observed in 31% of Crohn's disease visits and 21% of ulcerative colitis visits. Disease duration and health confidence were associated with discordance.

BACKGROUND: Histological disease severity assessment in ulcerative colitis [UC] has become a mainstay in the definition of clinical endpoints ['histological remission'] in clinical trials of UC. Several scores have been established in the microscopic assessment of disease activity, but the Nancy index [NI] stands out as being the histological index with the fewest scoring items. To what extent histological assessment using the NI is affected by interobserver reliability in a real-word setting is poorly understood. We therefore performed a single-centre retrospective analysis of NI assessment in patients with UC. METHODS: We retrospectively evaluated the NI in two independent cohorts [total: 1085 biopsies, 547 UC patients] of clinically diagnosed UC patients, who underwent colonoscopy between 2007 and 2020. Cohort #1 consisted of 637 biopsies from 312 patients, while Cohort #2 consisted of 448 biopsies from 235 patients. Two blinded pathologists with different levels of expertise scored all biopsies from each cohort. A consensus conference was held for cases with discrepant scoring results. Finally, an overall consensus scoring was obtained from both cohorts. RESULTS: The interobserver agreement of the NI was substantial after the assessment of 1085 biopsy samples (κâ =â 0.796 [95% confidence interval, CI: 0.771-0.820]). An improvement of the interobserver agreement was found with increasing numbers of samples evaluated by both observers (Cohort #1: κâ =â 0.772 [95% CI: 0.739-0.805]; Cohort #2: κâ =â 0.829 [95% CI: 0.793-0.864]). Interobserver discordance was highest in NI grade 1 [observer 1: nâ =â 128; observer 2: nâ =â 236]. Interobserver discordance was lowest in NI grades 0 [observer 1: nâ =â 504; observer 2: nâ =â 479] and 3 [observer 1: nâ =â 71; observer 2: nâ =â 66]. CONCLUSION: The NI is an easy-to-use index with high interobserver reliability for assessment of the histological disease activity of UC patients in a real-world setting. While NI grades 0 and 3 had a high level of agreement between observers, NI grade 1 had a poorer level of agreement. This highlights the clinical need to specify histological characteristics leading to NI grade 1.

BACKGROUND: There are no data to assess the value associated with a treat-to-target (T2T) strategy based on tight control of mild-moderate ulcerative colitis (UC). AIM: To assess the cost-effectiveness of a T2T approach based on the normalisation of clinical signs and faecal calprotectin (FC) METHODS: A decision analytical Markov model was developed to compare T2T algorithm combining clinical symptoms and FC levels to define treatment response and the possible switch to the next treatment line (T2T-FC), and the reference strategy based only on symptoms. The model included five treatment lines and was conducted from the Italian national health service (NHS) perspective using a 3-year time horizon. The model calculated the incremental cost-effectiveness ratio as per relapse avoided. Deterministic and probabilistic sensitivity analyses were conducted. RESULTS: The cost-effectiveness analysis produced an increased time spent by a patient in clinical remission and FC ≤ 100 level (+0.177 years; about 2 months) and a decreasing number of relapses (-0.1937; -20.9%) per patient using a T2T-FC approach compared to only symptoms. Furthermore, the T2T-FC was associated with higher cost (+1795). The ICER estimated was 9263 per relapse avoided. These results were confirmed by sensitivity analyses. CONCLUSIONS: T2T-FC approach resulted in a higher benefit for mild-moderate UC patients in terms of time in remission and incidence of relapse but was associated with higher costs. Clinical trials and real-world clinical studies are needed to provide additional data on the cost-benefit of this approach.

OBJECTIVE: Physicians tend to focus on biomedical targets while little is known about issues important to patients. We aimed to identify critical concepts impacting patients with inflammatory bowel disease (IBD). DESIGN: We performed a survey of patients with IBD in biologic therapy (n=172) and used a validated qualitative method called group concept mapping (GCM) in patient workshops. The survey included 13 questions on attitudes toward symptoms and issues related to IBD. In the eight workshops, patients (n=26) generated statements later clustered into concepts identifying issues impacting a patient's life. Patients ranked the statements. RESULTS: In the survey, patients' mean age were 40 years (SD 13), 53% were women, and 38% had ulcerative colitis. They identified fatigue (57%) and stool frequency (46%) as the most critical symptoms impacting their daily lives regardless of disease activity. In the GCM workshops with Crohn's disease (n=13) (median age 42 years (IQR 39-51) and 62% were women), 335 statements divided among 10 concepts were generated, and the three most important concepts were 'Positive attitudes', 'Accept and recognition', and 'Sharing knowledge and experiences in life with Crohn's disease'. In the workshops with ulcerative colitis (n=13) (median age 43 years (IQR 36-49) and 69% were women), 408 statements divided into 11 concepts were generated; the most important concepts were 'Take responsibility and control over your life', 'Medication', and 'Everyday life with ulcerative colitis'. CONCLUSION: Focusing solely on IBD symptoms, patients identified fatigue and stool frequency to impact daily life the most. However, when investigating the disease burden in a broader perspective beyond classic IBD symptoms, patients identified concepts with focus on emotional health to be most important. TRIAL REGISTRATION: The Copenhagen University Hospital, Herlev and Gentofte approved the questionnaire and methodology (work-zone no: 18015429).

BACKGROUND: A gap remains in documenting the impact of anti-tumor necrosis factor therapy on disease burden in ulcerative colitis (UC) patients treated in a real-world setting. The use of patient-reported outcomes (PROs) has been discussed as a primary endpoint in the context of the FDA PRO Guidance, for labelling purposes. Specifically, the efficacy and safety of adalimumab have been demonstrated in pivotal trials; however, data are needed to understand how clinical results translate into improvements in key aspects of the daily lives of UC patients, such as symptoms, health-related quality of life (HRQoL), and disability. AIM: To assess real-world effectiveness of adalimumab on PRO measures in patients with moderate-to-severe UC. METHODS: UCanADA was a single arm, prospective, 1-year multicenter Canadian post-marketing observational study in which multiple PRO questionnaires were completed-with psychologic distress/depression symptoms as the primary endpoint-by patients with moderate-to-severe UC. Assessments were performed during patients' routine care visit schedule, which was at the initiation of adalimumab (baseline), after induction (approximately 8 wk), and 52 wk after baseline. Additional optional assessments between weeks 8 and 52 were collected at least once but no more than two times during this period. Serious safety events and per-protocol adverse events were collected. RESULTS: From 23 Canadian centres, 100 patients were enrolled and 48 completed the study. Measured with the Patient Health Questionnaire-9 items at week 52, 61.5% (40/65) [95% confidence interval (CI): 49.7%-73.4%] of the patients improved in psychologic distress/depression symptoms, which was slightly higher in completers [65.9% (29/44); 95%CI: 51.9%-79.9%)]. At week 52, clinical response and clinical remission were achieved respectively by 65.7% (44/73) and 47.8% (32/73) of the patients. The odds of improving depressive symptoms for those achieving a clinical remission at week 52 was 7.94 higher compared with those not achieving a clinical remission (CI: 1.42, 44.41; P = 0.018). Significant changes from baseline to weeks 8 and 52 were observed in disability, HRQoL, and fatigue. Meaningful improvement was reported in work impairment. CONCLUSION: At week 52, over 60% of the UCanADA patients had depressive symptoms significantly reduced, as well as HRQoL, fatigue symptoms, and work impairment improved. No new safety signals were detected.
