Background: The 'United Registries for Clinical Assessment and Research' [UR-CARE] database is an initiative of the European Crohn's and Colitis Organisation [ECCO] to facilitate daily patient care and research studies in inflammatory bowel disease [IBD]. Herein, we sought to validate the database by using fictional case histories of patients with IBD that were to be entered by observers of varying experience in IBD. Methods: Nineteen observers entered five patient case histories into the database. After 6 weeks, all observers entered the same case histories again. For each case history, 20 key variables were selected to calculate the accuracy for each observer. We assumed that the database was such that = 90% of the entered data would be correct. The overall proportion of correctly entered data was calculated using a beta-binomial regression model to account for inter-observer variation and compared to the expected level of validity. Re-test reliability was assessed using McNemar's test. Results: For all case histories, the overall proportion of correctly entered items and their confidence intervals included the target of 90% (Case 1: 92% [88-94%]; Case 2: 87% [83-91%]; Case 3: 93% [90-95%]; Case 4: 97% [94-99%]; Case 5: 91% [87-93%]). These numbers did not differ significantly from those found 6 weeks later [NcNemar's test p > 0.05]. Conclusion: The UR-CARE database appears to be feasible, valid and reliable as a tool and easy to use regardless of prior user experience and level of clinical IBD experience. UR-CARE has the potential to enhance future European collaborations regarding clinical research in IBD., SCOPUS: ar.j, info:eu-repo/semantics/published

Background and Aims: The ECCO-EpiCom study investigates the differences in the incidence and therapeutic management of inflammatory bowel diseases [IBD] between Eastern and Western Europe. The aim of this study was to analyse the differences in the disease phenotype, medical therapy, surgery, and hospitalization rates in the ECCO-EpiCom 2011 inception cohort during the first year after diagnosis. Methods: Nine Western, five Eastern European centres and one Australian centre with 258 Crohn’s disease [CD], 380 ulcerative colitis [UC] and 71 IBD unclassified [IBDU] patients [female/male: 326/383; mean age at diagnosis: 40.9 years, SD: 17.3 years] participated. Patients’ data were registered and entered in the web-based ECCO-EpiCom database [www.epicom-ecco.eu]. Results: In CD, 36 [19%] Western Europe/Australian and 6 [9%] Eastern European patients received biological therapy [p = 0.04], but the immunosuppressive [IS] use was equal and high in these regions [Eastern Europe vs Western Europe/Australia: 53% vs 45%; p = 0.27]. Surgery was performed in 17 [24%] CD patients in Eastern Europe and 13 [7%] in Western Europe/Australia [p < 0.001, pLogRank = 0.001]. Of CD patients from Eastern Europe, 24 [34%] were hospitalized, and 39 [21%] from Western Europe/Australia, [p = 0.02, pLogRank = 0.01]. In UC, exposure to biologicals and colectomy rates were low and hospitalization rates did not differ between these regions during the 1-year follow-up period [16% vs 16%; p = 0.93]. Conclusions: During the first year after diagnosis, surgery and hospitalization rates were significantly higher in CD patients in Eastern Europe compared with Western Europe/Australia, whereas significantly more CD patients were treated with biologicals in the Western Europe/Australian centres., BACKGROUND AND AIMS: The ECCO-EpiCom study investigates the differences in the incidence and therapeutic management of inflammatory bowel diseases [IBD] between Eastern and Western Europe.

Objective The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East–West gradient in the incidence of IBD in Europe exists. Design A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience. Results 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100 000 in 2010 for CD were 6.5 (range 0–10.7) in Western European centres and 3.1 (range 0.4–11.5) in Eastern European centres, for UC 10.8 (range 2.9–31.5) and 4.1 (range 2.4–10.3), respectively, and for IBDU 1.9 (range 0–39.4) and 0 (range 0–1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy. Conclusions An East–West gradient in IBD incidence exists in Europe. Among

Background and Aims: The EpiCom study and inception cohort was initiated in 2010 in 31 centers from 14 Western and 8 Eastern European countries, covering a 10.1 million person background population. Our aim was to investigate whether there is a difference between Eastern and Western Europe in health care and education of patients with inflammatory bowel disease (IBD). Methods: A quality of care (QoC) questionnaire was developed in the EpiCom group consisting of 16 questions covering 5 items: time interval between the onset of symptoms and diagnosis, information, education, empathy and access to health care providers. Results: Of 1,515 patients, 947 (217 east/730 west) answered the QoC questionnaire. Only 23% of all patients had knowledge about IBD before diagnosis. In Eastern Europe, significantly more patients searched out information about IBD themselves (77% vs. 68%, p < 0.05), the main source was the Internet (92% vs. 88% p = 0.23). In Western Europe, significantly more patients were educated by nurses (19% vs. 1%, p < 0.05), while in Eastern Europe, gastroenterologists were easier to contact (80% vs. 68%, p < 0.05). Conclusion: Health care differed significantly between Eastern and Western Europe in all items, but satisfaction rates were high in both geographic regions. Because of the low awareness and the rising incidence of IBD, general information should be the focus of patient organizations and medical societies. In Western Europe IBD nurses play a very important role in reducing the burden of patient management. (c) 2014 European Crohn's and Colitis Organisation. Published by Elsevier B.V.

BACKGROUND AND AIMS: The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe possibly due to changes in environmental factors towards a more "westernised" standard of living. The aim of this study was to investigate differences in exposure to environmental factors prior to diagnosis in Eastern and Western European IBD patients.METHODS: The EpiCom cohort is a population-based, prospective inception cohort of 1560 unselected IBD patients from 31 European countries covering a background population of 10.1 million. At the time of diagnosis patients were asked to complete an 87-item questionnaire concerning environmental factors.RESULTS: A total of 1182 patients (76%) answered the questionnaire, 444 (38%) had Crohn's disease (CD), 627 (53%) ulcerative colitis (UC), and 111 (9%) IBD unclassified. No geographic differences regarding smoking status, caffeine intake, use of oral contraceptives, or number of first-degree relatives with IBD were found. Sugar intake was higher in CD and UC patients from Eastern Europe than in Western Europe while fibre intake was lower (p<0.01). Daily consumption of fast food as well as appendectomy before the age of 20 was more frequent in Eastern European than in Western European UC patients (p<0.01). Eastern European CD and UC patients had received more vaccinations and experienced fewer childhood infections than Western European patients (p<0.01).CONCLUSIONS: In this European population-based inception cohort of unselected IBD patients, Eastern and Western European patients differed in environmental factors prior to diagnosis. Eastern European patients exhibited higher occurrences of suspected risk factors for IBD included in the Western lifestyle.

BACKGROUND AND AIMS: The aim of the present study was to validate the IBD (inflammatory bowel diseases) incidence reported in the 2010 ECCO-EpiCom (European Crohn's and Colitis Organization-Epidemiological Committee) inception cohort by including a second independent inception cohort from participating centers in 2011 and an Australian center to investigate whether there is a difference in the incidence of IBD between Eastern and Western European countries and Australia.METHODS: Fourteen centers from 5 Eastern and 9 Western European countries and one center from Australia participated in the ECCO-EpiCom 2011 inception cohort. Patients' data regarding disease type, socio-demographic factors, extraintestinal manifestations and therapy were entered into the Web-based EpiCom database, www.ecco-epicom.eu.RESULTS: A total of 711 adult patients were diagnosed during the inclusion year 2011, 178 (25%) from Eastern, 461 (65%) from Western Europe and 72 (10%) from Australia; 259 (37%) patients were diagnosed with Crohn's disease, 380 (53%) with ulcerative colitis and 72 (10%) with IBD unclassified. The mean annual incidence rate for IBD was 11.3/100,000 in Eastern Europe, 14.0/100,000 in Western Europe and 30.3/100,000 in Australia. Significantly more patients were diagnosed with complicated disease at diagnosis in Eastern Europe compared to Western Europe (43% vs. 27%, p=0.02).CONCLUSION: Incidence rates, disease phenotype and initial treatment characteristics in the 2011 ECCO-EpiCom cohort were not significantly different from that reported in the 2010 cohort.

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., Munkholm, P.

BACKGROUND: Infliximab (IFX) maintenance therapy for Crohn's disease (CD) is administered every 8 weeks, but inter-patient variation in optimal treatment intervals may exist. AIM: To assess, in a prospective pilot study, the efficacy, safety and quality of life (QoL) of IFX maintenance treatment scheduled through web-based self-monitoring of disease activity. METHODS: Twenty-seven CD patients in IFX maintenance therapy were enrolled and received a standardised disease education and web-training. Using the http://www.cd.constant-care.dk concept, patients recorded their disease activity and faecal calprotectin weekly. From this, the inflammatory burden (IB) score was calculated, placing patients in the green, yellow or red zones of a 'traffic light' system. If placed in the yellow or red zones, the computer directed these patients to consult their physician for IFX infusion. RESULTS: Seventeen patients (63%) completed 52 weeks of follow-up, 6 (22%) completed 26 weeks and 4 (15%) were excluded due to loss of response, patient decision or non-adherence. In total, 121 IFX infusions were given with a median interval of 9 (range: 4-18) weeks. Only 10% of infusions were given at 8-week intervals, whereas 39% were administered with shorter and 50% with longer intervals respectively. The mean IB and the QoL remained stable during the web-treatment. One mild infusion reaction and one case of folliculitis were observed, while three patients underwent surgery. CONCLUSIONS: The program http://www.cd.constant-care.dk appears to be a practical and safe concept for the individualised scheduling of maintenance treatment with IFX in patients with Crohn's disease. Larger studies are awaited to confirm this preliminary outcome.

BACKGROUND: Forecasting clinical and economic outcomes in ulcerative colitis (UC) and Crohn's disease (CD) patients is complex, but necessary.AIMS: To determine: the frequency of treatment-classified clinical states; the probability of transition between states; and the economic outcomes.METHODS: Newly diagnosed UC and CD patients, allocated into seven clinical states by medical and surgical treatments recorded in serial 3-month cycles, underwent Markov analysis.RESULTS: Over 10 years, 630 UC and 318 CD patients had 22,823 and 11,871 cycles. The most frequent clinical outcomes were medical/surgical remission (medication-free) and mild disease (on 5-aminosalicylates, antibiotics, topical corticosteroids), comprising 28% and 62% of UC cycles and 24% and 51% of CD cycles respectively. The probability of drug-response in patients receiving systemic corticosteroids/immunomodulators was 0.74 in UC, 0.66 in CD. Both diseases had similar likelihood of persistent drug-dependency or drug-refractoriness. Surgery was more probable in CD, 0.20, than UC, 0.08. In terms of economic outcomes, surgery was costlier in UC per cycle, but the outlay over 10 years was greater in CD. Drug-refractory UC and CD cases engendered high costs in the cohort.CONCLUSIONS: Most patients on 5-aminosalicylates, corticosteroids and immunomodulators had favourable clinical and economic outcomes over 10 years. Drug-refractory and surgical patients exhibited greater long-term expenses.

BACKGROUND: The evidence concerning the use of isosorbide-mononitrate (IsMn) for oesophageal varices is equivocal.AIM: To assess the effects of IsMn for patients with oesophageal varices and no previous bleeding (primary prevention) or previous variceal bleeding (secondary prevention).METHODS: Systematic review with meta-analyses of randomized trials on IsMn alone or with beta-blockers or endoscopic therapy for oesophageal varices. Electronic and manual searches were combined. Randomized trials on primary and secondary prevention were included. The primary outcome measure was mortality. Intention-to-treat random effects meta-analyses were performed. The robustness of the results was assessed in trial sequential analyses.RESULTS: Ten randomized trials on primary and 17 on secondary prevention were included. Evidence of bias was identified. No apparent effect of IsMn on mortality compared with placebo or beta-blockers or IsMn plus beta-blockers vs. beta-blockers was identified. Compared with endoscopic therapy, IsMn plus beta-blockers had no apparent effect on bleeding, but did seem to reduce mortality in secondary prevention (RR 0.73, 95% CI 0.59-0.89), but not in primary prevention. The effect of IsMn plus beta-blockers on mortality in secondary prevention was not confirmed in trial sequential analysis.CONCLUSIONS: Isosorbide-mononitrate used alone or in combination with beta blockers does not seem to offer any reduction in bleeding in the primary or secondary prevention of oesophageal varices. Compared with endoscopic therapy, there may be a survival advantage in using IsMn and beta-blockers, but additional large multicentre trials are needed to verify this finding.

BACKGROUND: In Crohn's disease (CD), studies associating phenotype at diagnosis and subsequent disease activity are important for patient counselling and health care planning.AIMS: To calculate disease recurrence rates and to correlate these with phenotypic traits at diagnosis.METHODS: A prospectively assembled uniformly diagnosed European population based inception cohort of CD patients was classified according to the Vienna classification for disease phenotype at diagnosis. Surgical and non-surgical recurrence rates throughout a 10 year follow up period were calculated. Multivariate analysis was performed to classify risk factors present at diagnosis for recurrent disease.RESULTS: A total of 358 were classified for phenotype at diagnosis, of whom 262 (73.2%) had a first recurrence and 113 patients (31.6%) a first surgical recurrence during the first 10 years after diagnosis. Patients with upper gastrointestinal disease at diagnosis had an excess risk of recurrence (hazard ratio 1.54 (95% confidence interval (CI) 1.13-2.10)) whereas age >/=40 years at diagnosis was protective (hazard ratio 0.82 (95% CI 0.70-0.97)). Colonic disease was a protective characteristic for resective surgery (hazard ratio 0.38 (95% CI 0.21-0.69)). More frequent resective surgical recurrences were reported from Copenhagen (hazard ratio 3.23 (95% CI 1.32-7.89)).CONCLUSIONS: A mild course of disease in terms of disease recurrence was observed in this European cohort. Phenotype at diagnosis had predictive value for disease recurrence with upper gastrointestinal disease being the most important positive predictor. A phenotypic North-South gradient in CD may be present, illustrated by higher surgery risks in some of the Northern European centres.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) often affects patients in their fertile age. The aim of this study was to describe pregnancy outcome in a European cohort of IBD patients. As data are limited regarding the effect of pregnancy on disease course, our second objective was to investigate whether pregnancy influences disease course and phenotype in IBD patients. METHODS: In a European cohort of IBD patients, a 10-yr follow-up was performed by scrutinizing patient files and approaching the patients with a questionnaire. The cohort comprised 1,125 patients, of whom 543 were women. Data from 173 female ulcerative colitis (UC) and 93 Crohn's disease (CD) patients form the basis for the present study. RESULTS: In all, 580 pregnancies, 403 occurring before and 177 after IBD was diagnosed, were reported. The rate of spontaneous abortion increased after IBD was diagnosed (6.5% vs. 13%, p = 0.005), whereas elective abortion was not significantly different. 48.6% of the patients took medication at the time of conception and 46.9% during pregnancy. The use of cesarean section increased after IBD diagnosis (8.1% vs 28.7% of pregnancies). CD patients pregnant during the disease course, did not differ from patients who were not pregnant during the disease course regarding the development of stenosis (37% vs 52% p = 0.13) and resection rates (mean number of resections 0.52 vs 0.66, p = 0.37). The rate of relapse decreased in the years following pregnancy in both UC (0.34 vs 0.18 flares/yr, p = 0.008) and CD patients (0.76 vs 0.12 flares/yr, p = 0.004). CONCLUSIONS: Pregnancy did not influence disease phenotype or surgery rates, but was associated with a reduced number of flares in the following years.

BACKGROUND: Heparin has anti-inflammatory and immunomodulatory activity which may be of therapeutic benefit in the treatment of ulcerative colitis.AIM: To test whether low molecular weight heparin, given subcutaneously, would provide a significant therapeutic response compared with placebo in the treatment of mild to moderate ulcerative colitis.STUDY DESIGN: A prospective, double-blind, randomized, placebo-controlled, multi-centre trial comparing tinzaparin 175 anti-Xa IU/kg/day (innohep, LEO Pharma) subcutaneously for 14 days followed by tinzaparin 4500 anti-Xa IU/day subcutaneously for 28 days with placebo, administered subcutaneously once daily for up to 42 days. The primary outcome measure was the mean change in colitis activity from baseline to the end of study treatment assessed by the sum of scores of stool frequency, rectal bleeding, sigmoidoscopic appearance and histology. Secondary outcome measures included changes in individual activity indices and laboratory parameters. Patients were assessed at weekly intervals for 6 weeks and within 1 week of completing treatment.RESULTS: One hundred patients with active ulcerative colitis (up to six bloody stools per day, no fever, no tachycardia or systemic disturbances) were randomized. Forty-eight received tinzaparin and 52 received placebo. The difference in the mean percentage change in colitis activity from baseline to end of treatment (tinzaparin-placebo) was not statistically significant (P = 0.84). There was no difference between tinzaparin and placebo in any secondary outcome measure. One major bleed (rectal), occurred in a patient receiving placebo.CONCLUSION: This is the largest trial to date of heparin in ulcerative colitis. The results show no benefit of low molecular weight heparin over placebo in mild to moderately active ulcerative colitis.

In the literature there are indications of associations between health-related quality of life (HRQoL) in inflammatory bowel disease and disease activity, psychological status, coping, stressful life events, and social support. The aim of this study was to examine whether a relation exists between quality of health care and HRQoL, taking possible confounding variables into account. For this purpose, one single questionnaire was compiled from existing validated questionnaires. A population-based inception cohort of 1056 patients with inflammatory bowel disease in eight countries, diagnosed 6 to 8 years prior to the study, was approached to participate. In total, 824 patients responded (78%), and 517 could be included in statistical analyses. It was shown that in inflammatory bowel disease HRQoL was indeed influenced by quality of care (particularly with regard to the parameters of "providing information," " costs," and "courtesy"), as well as by disease activity, psychological status, type of hospital, social support, stressful life events, and way of administration of the questionnaire. Patients with active disease had lower psychological status and HRQoL scores at the time of the survey than patients without active disease. However, quality of care scores did not differ between these groups. The care aspect "costs" was scored worse by CD compared with UC patients, probably caused by a potentially more expensive treatment. In conclusion, it is shown in a large exploratory study, for the first time, that in inflammatory bowel disease, quality of care has a significant role in determining health-related quality of life.

AIM: To determine the long-term risk of intestinal and extra-intestinal malignancies in Crohn's disease patients in Copenhagen County, Denmark.METHODS: In Copenhagen County, a strictly population-based cohort of 374 patients with Crohn's disease diagnosed between 1962 and 1987 was followed until 1997 in order to determine the long-term risk of intestinal and extra-intestinal malignancies. Information on cancer occurrence was provided by the Danish National Cancer Registry and confirmed by the examination of hospital files. The observed number of cases was compared with the expected number, calculated from individually computed person-years at risk and 1995 cancer incidence rates for the background population.RESULTS: The risk of small bowel adenocarcinoma was significantly increased, independent of age and gender (standardized morbidity ratio, 66.7; 95% confidence interval, 18.1-170.7). The risk of colorectal cancer was not increased, either in the total group of patients or in patients with colonic Crohn's disease exclusively (standardized morbidity ratio, 1.64; 95% confidence interval, 0.20-5.92). Extra-intestinal cancer did not occur more frequently than expected.CONCLUSIONS: This population-based study of patients with Crohn's disease revealed no increase in colorectal cancer risk, possibly due to maintenance treatment with 5-aminosalicylic acid preparations and surgery in treatment failure. In contrast, the risk of small bowel cancer was increased more than 60-fold, but the numbers were small. The risk of extra-intestinal cancer was not increased and no lymphomas were observed.

Inflammatory bowel disease (IBD) is associated with an increased risk of developing intestinal cancer at sites of chronic inflammation. Aminosalicylates, including both sulfasalazine and mesalamine, are the most commonly prescribed anti-inflammatory agents prescribed in IBD. On balance, the body of literature to date suggests that aminosalicylates confer some protection against the development of colonic neoplasia in patients with IBD and in a variety of models, including in the noninflamed gut. This latter observation implies that aminosalicylates may be of chemopreventive value in normal as well as IBD individuals. The current review examines and gives an overview of the evidence from a variety of sources, including epidemiological, in vivo and in vitro studies that have investigated the potential anticancer effects of aminosalicylates.
