Abstract
BACKGROUND AND AIMS The long-term course of ulcerative colitis [UC] is difficult to predict. Mortality, colectomy, cancer, and hospitalisation represent hard outcomes of disease. Moreover, knowledge on the risk of relapses and need for potent medication add important information about living with UC. We aimed to evaluate the course and prognosis of UC during the first 20 years after diagnosis, and to identify early prognostic risk factors. METHODS From 1990 to 1994, a population-based inception cohort of patients with inflammatory bowel disease was enrolled in South-Eastern Norway. A systematic follow-up [FU] was conducted at 1,5, 10, and 20 years after diagnosis. Clinical outcomes were recorded continuously, and possible relationships between early disease characteristics and outcomes were analysed using multiple regression analysis. RESULTS Among 519 UC patients, 119 died, 60 were lost to FU, and 340 were included in the FU cohort. The 20-year cumulative risk of colectomy was 13.0% (95% confidence interval [CI] [11.4-14.6]). Extensive colitis at diagnosis was independently associated with an increased risk of colectomy compared with proctitis (hazard ratio [HR] = 2].8, 95% CI [1.3-6.1]). In contrast, mucosal healing at 1-year FU was independently associated with reduced risk of colectomy [HR = 0.4, 95% CI [0.2-0.8]), and inversely associated with subsequent risk of relapse [adjusted HR = 0.5, 95% CI [0.3-0.7]). CONCLUSIONS The overall risk of colectomy in our cohort was lower than expected from previous studies, although considerable for patients with extensive colitis at diagnosis. Early mucosal healing was associated with better disease outcomes 20 years after diagnosis.

Abstract
Objective The association between ulcerative colitis (UC) and colorectal cancer (CRC) is widely accepted, although attenuated risk has been reported in recent years. Colonoscopic surveillance is recommended with intervals based on established clinical risk factors. Nevertheless, a significant number of patients develop interval cancers, indicating the need of improved individualised assessment. In the present study, we evaluated clinical risk factors associated with CRC during a prescheduled follow-up 20 years after diagnosis, the IBSEN study. Design A population-based inception cohort of patients diagnosed with inflammatory bowel disease from 1 January 1990 until 31 December 1993, prospectively followed at 1, 5, 10 and 20 years after diagnosis. A total of 517 patients with UC were included; 264 (51 %) men; median age at inclusion 37.4 years (4–88). Results The overall incidence of CRC was 1.6% (8/517) at a 20-year follow-up. The total lifetime risk of CRC prior to or after UC diagnosis was 2.3%. (12/517). Patients older than 70 years at diagnosis had a 15-fold higher risk of CRC compared with those diagnosed when younger than 40 years, with HR 15.68 (95% CI: 1.31 to 187.92). Neither sex, first-degree relative with CRC, extent of colitis nor primary sclerosing cholangitis affected the risk of CRC. Conclusion The risk of CRC in UC was low and comparable with the risk of CRC in the background population of Norway.

Abstract
BACKGROUND Ulcerative colitis (UC) negatively affects health-related quality of life (HRQoL), but population-based and long-term data on this topic are scarce. Our aim was to determine the HRQoL in UC patients after a 10-year disease duration. METHODS UC patients from a population-based inception cohort met at a prescheduled 10-year follow-up visit. In addition to a clinical examination, interview, and blood samples, the patients completed the Short Form 36 (SF-36) and the Norwegian Inflammatory Bowel Disease Questionnaire (N-IBDQ). The SF-36 scores were compared to scores from a general population sample using one-sample t-tests. Standardized scores were calculated and interpreted according to Cohen's effect size index. The associations between relevant clinical and demographic factors and HRQoL were examined through linear regression analyses. RESULTS A total of 196 patients completed the HRQoL questionnaires (response rate: 80%), of whom 54% were women; the mean age of all patients was 48 years (range: 22-86). The SF-36 scores were comparable to those of the general population except for lower scores in the General Health dimension. The SF-36 scores were significantly lower in the presence of current symptoms, in patients who had used corticosteroids, and in patients who reported not working. Overall N-IBDQ scores were equivalent to scores of patients in remission. Female gender, work status (not working), current symptoms, and smoking were associated with significantly lower N-IBDQ scores. CONCLUSIONS SF-36 scores were not reduced compared to the general population sample. The presence of current symptoms, the use of corticosteroids, work status (not working), female gender, and smoking had a negative impact on HRQoL.

Abstract
BACKGROUND AND AIMS Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. METHODS We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. RESULTS The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. CONCLUSIONS In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.

Abstract
BACKGROUND Crohn's disease (CD) is a chronic inflammation of the gastrointestinal tract associated with life-long high health care costs. We aimed to determine the effect of disease phenotype on cost. METHODS Clinical and economic data of a community-based CD cohort with 10-year follow-up were analyzed retrospectively in relation to Montreal classification phenotypes. RESULTS In 418 patients, mean total costs of health care for the behavior phenotypes were: nonstricturing-nonpenetrating 1690, stricturing 2081, penetrating 3133 and penetrating-with-perianal-fistula 3356 €/patient-phenotype-year (P<0.001), and mean costs of surgical hospitalization 215, 751, 1293 and 1275 €/patient-phenotype-year respectively (P<0.001). Penetrating-with-perianal-fistula patients incurred significantly greater expenses than penetrating patients for total care, diagnosis and drugs, but not surgical hospitalization. Total costs were similar in the location phenotypes: ileum 1893, colon 1748, ileo-colonic 2010 and upper gastrointestinal tract 1758 €/patient-phenotype-year, but surgical hospitalization costs differed significantly, 558, 209, 492 and 542 €/patient-phenotype-year respectively (P<0.001). By multivariate analysis, the behavior phenotype significantly impacted total, medical and surgical hospitalization costs, whereas the location phenotype affected only surgical costs. Younger age at diagnosis predicted greater surgical expenses. CONCLUSIONS Behavior is the dominant phenotype driving health care cost. Use of the Montreal classification permits detection of cost differences caused by perianal fistula.

Abstract
OBJECTIVE To determine dysplasia and cancer in the 1991-2004 European Collaborative Inflammatory Bowel Disease (EC-IBD) Study Group cohort. PATIENTS AND METHODS A patient questionnaire and a physician per patient form were completed for each of the 1,141 inflammatory bowel disease patients (776 ulcerative colitis/365 Crohn's disease) from 9 centers (7 countries) derived from the EC-IBD cohort. Rates of detection of intestinal cancer and dysplasia as well as extra-intestinal neoplasms were computed. RESULTS Patient follow-up time was 10.3 +/- 0.8 (range 9.4-11) years. The mean age of the whole group of IBD patients was 37.8 +/- 11.3 (range 16-76) years. Thirty-eight patients (3.3%; 26 with ulcerative colitis/12 with Crohn's disease, 21 males/17 females, aged 61.3 +/- 13.4, range 33-77 years), were diagnosed with 42 cancers. Cancers occurred 5.4 +/- 3.3 (range 0-11) years after inflammatory bowel disease diagnosis. Colorectal cancer was diagnosed in 8 (1 Crohn's disease and 7 ulcerative colitis patients--0.3 and 0.9% of the Crohn's disease and ulcerative colitis cohort, respectively) of 38 patients and 30 cancers were extra-intestinal. Four of 38 patients (10.5%) were diagnosed as having 2 cancers and they were younger compared to patients with one cancer (p = 0.0008). There was a trend for a higher prevalence of intestinal cancer in the northern centers (0.9%) compared to southern centers (0.3%, p = NS). Southern centers had more cases of extra-intestinal cancer compared to northern centers (2 vs. 3.8%, p = 0.08). Ten patients (0.9%; 8 with ulcerative colitis/2 with Crohn's disease, 8 males, aged 62.3 +/- 14.1 years) had colorectal dysplasia. CONCLUSIONS In the first decade of the EC-IBD Study Group cohort follow-up study, the prevalence of cancer was as expected with most patients having a single neoplasm and an extra-intestinal neoplasm. In northern centers there was a trend for more intestinal cancers, while in southern centers there was a trend for more extra-intestinal cancers compared to northern centers.

Abstract
BACKGROUND NOD2/CARD15, the first identified susceptibility gene in Crohn's disease (CD), is associated with ileal stenosis and increased frequency of surgery. Anti-Saccharomyces cerevisiae antibody (ASCA), a serological marker for CD, is associated with ileal location and a high likelihood for surgery. We hypothesized that the presence of ASCA and NOD2/CARD15 mutations could predict increased health care cost in CD. METHODS CD patients in a prospectively designed community-based multinational European and Israeli cohort (n = 228) followed for mean 8.3 (SD 2.6) years had blood drawn for measurement of ASCA (IgG, IgA), Arg702Trp, Gly908Arg, and Leu1007fsinsC. Days spent in the hospital and the costs of medical and surgical hospitalizations and medications were calculated. RESULTS The median duration of surgical hospitalizations was longer in Gly908Arg-positive than -negative patients, 3.5 and 1.5 days/patient-year (P < 0.01), and in ASCA-positive than -negative patients, 1.1 and 0 days/patient-year (P < 0.001). Median surgical hospitalization cost was 1,580 euro/patient-year in Gly908Arg-positive versus 0 euro/patient-year in -negative patients (P < 0.01), and 663 euro/patient-year in ASCA-positive versus 0 euro/patient-year in -negative patients (P < 0.001). Differences in cost of medications between groups were not significant. The effect of Gly908Arg was expressed in countries with higher Gly908Arg carriage rates. ASCA raised surgical costs independently of the age at diagnosis of disease. Arg702Trp and Leu1007fsinsC did not affect the cost of health care. CONCLUSIONS Since CD patients positive for Gly908Arg and ASCA demonstrated higher health care costs, it is possible that measurement of Gly908Arg and ASCA at disease diagnosis can forecast the expensive CD patients.

Abstract
BACKGROUND & AIMS The colectomy rate in ulcerative colitis (UC) is related to morbidity and to treatment decisions made during disease course. The aims of this study were to determine the colectomy risk in UC in the first decade after diagnosis and to identify factors that may influence the choice of surgical treatment. METHODS In 1991-1993, 781 UC patients from 9 centers located in 7 countries in northern and southern Europe and in Israel were included in a prospective inception cohort study. After 10 years of follow-up, 617 patients had complete medical records, 73 had died, and 91 had been lost to follow-up. RESULTS There were no significant differences in age, sex, or disease extent at diagnosis between patients followed for 10 years and those lost to follow-up. The 10-year cumulative risk of colectomy was 8.7%: 10.4% in the northern and 3.9% in the southern European centers (P < .001). Colectomy was more likely in extensive colitis than in proctitis, with an adjusted hazard ratio (HR) of 4.1 (95% CI: 2.0-8.4). Compared with the southern centers, the adjusted HR was 2.7 (95% CI: 1.3-5.6) for The Netherlands and Norway together and 8.2 (95% CI: 3.6-18.6) for Denmark. Age at diagnosis, sex, and smoking status at diagnosis had no statistically significant influence on colectomy rates. CONCLUSIONS The colectomy rate was found to be lower than that in previous publications, but there was a difference between northern and southern Europe. Colectomy was associated with extensive colitis, but the geographic variations could not be explained.

Abstract
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.

Abstract
OBJECTIVE To give a general outline of a 10-year clinical follow-up study of a population-based European cohort of inflammatory bowel disease (IBD) patients and to present the first results in terms of clinical outcome parameters and risk factors. MATERIALS AND METHODS A population-based cohort of newly, prospectively, diagnosed cases was initiated between 1991 and 1993. The 2201 patients with IBD (706 had Crohn's disease (CD), 1379 had ulcerative colitis (UC) and 116 had indeterminate colitis) originated from 20 different areas in 11 different European countries and Israel. For the 10-year follow-up of this cohort, electronic data-collecting instruments were made available through an Internet-based website. Data concerning vital status, disease activity, medication use, surgical events, cancer, pregnancy, fertility, quality of life and health-care costs were gathered. A blood sample was obtained from patients and controls to perform genotypic characterization. RESULTS Thirteen centres from eight European countries and Israel participated. In 958 (316 CD and 642 UC) out of a total of 1505 IBD patients (64%) from these 13 centres, a complete dataset was obtained at follow-up. Even though an increased mortality risk was observed in CD patients 10 years after diagnosis, a benign disease course was observed in this patient group in terms of disease recurrence. A correlation between ASCA and CARD15 variants in CD patients and complicated disease course was observed. A north-south gradient was observed regarding colectomy rates in UC patients. Direct costs were found to be highest in the first year after diagnosis and greater in CD patients than in UC patients, with marked differences between participating countries. CONCLUSIONS This 10-year clinical follow-up study of a population-based European cohort of IBD patients provides updated information on disease outcome of these patient groups.

Abstract
BACKGROUND High Helicobacter pylori eradication rates have consistently been reported with 2-week dual therapy regimens of ranitidine bismuth citrate plus clarithromycin. Ranitidine bismuth citrate with two antibiotics may provide an alternative 1-week eradication regimen. METHODS This double-blind, randomized, parallel group, international, multicentre study compared ranitidine bismuth citrate 400 mg b.d. and clarithromycin 500 mg b.d. for 2 weeks (RC) with ranitidine bismuth citrate 400 mg b.d., clarithromycin 500 mg b.d. and metronidazole 400 mg b.d. for 1 week (RCM) for eradication of H. pylori in 350 patients with dyspepsia. RESULTS Treatment with RC and RCM eradicated H. pylori (established by the combination of two negative results from two discrete 13C-UBTs at nominal weeks 4 and 12) from 89% (95% CI: 84-94) and 92% (95% CI: 88-97) of the observed population, and from 78% (95% CI: 72-84) and 80% (95% CI: 75-86) of the intention-to-treat population. When established only by one negative 13C-UBT result at least 28 days after the end of treatment, the respective intention-to-treat rates were 85% (95% CI: 79-90) and 88% (95% CI: 83-93). Both regimens were well-tolerated, only 6% of patients given RC and 4% given RCM discontinued treatment. Median plasma bismuth concentrations at the end of the second week of study were low, at 3.5 and 0.4 ng/ mL, respectively. CONCLUSIONS Ranitidine bismuth citrate triple therapy for 1 week (RCM) and dual therapy for 2 weeks (RC) were equally effective for the eradication of H. pylori infection.
