BACKGROUND: The lack of scientific evidence regarding the effectiveness of 5-aminosalicylate in patients with Crohn's disease is in sharp contrast to its widespread use in clinical practice. AIMS: The aim of the study was to investigate the use of 5-aminosalicylate in patients with Crohn's disease as well as the disease course of a subgroup of patients who were treated with 5-aminosalicylate as maintenance monotherapy during the first year of disease. METHODS: In a European community-based inception cohort, 488 patients with Crohn's disease were followed from the time of their diagnosis. Information on clinical data, demographics, disease activity, medical therapy and rates of surgery, cancers and deaths was collected prospectively. Patient management was left to the discretion of the treating gastroenterologists. RESULTS: Overall, 292 (60%) patients with Crohn's disease received 5-aminosalicylate period during follow-up for a median duration of 28 months (interquartile range 6-60). Of these, 78 (16%) patients received 5-aminosalicylate monotherapy during the first year following diagnosis. Patients who received monotherapy with 5-aminosalicylate experienced a mild disease course with only nine (12%) who required hospitalization, surgery, or developed stricturing or penetrating disease, and most never needed more intensive therapy. The remaining 214 patients were treated with 5-aminosalicylate as the first maintenance drug although most eventually needed to step up to other treatments including immunomodulators (75 (35%)), biological therapy (49 (23%)) or surgery (38 (18%)). CONCLUSION: In this European community-based inception cohort of unselected Crohn's disease patients, 5-aminosalicylate was commonly used. A substantial group of these patients experienced a quiescent disease course without need of additional treatment during follow-up. Therefore, despite the controversy regarding the efficacy of 5-aminosalicylate in Crohn's disease, its use seems to result in a satisfying disease course for both patients and physicians.

BACKGROUND: Inflammatory bowel disease (IBD) places a significant burden on health-care systems because of its chronicity and need for expensive therapies and surgery. With increasing use of biological therapies, contemporary data on IBD health-care costs are important for those responsible for allocating resources in Europe. To our knowledge, no prospective long-term analysis of the health-care costs of patients with IBD in the era of biologicals has been done in Europe. We aimed to investigate cost profiles of a pan-European, community-based inception cohort during 5 years of follow-up. METHODS: The Epi-IBD cohort is a community-based, prospective inception cohort of unselected patients with IBD diagnosed in 2010 at centres in 20 European countries plus Israel. Incident patients who were diagnosed with IBD according to the Copenhagen Diagnostic Criteria between Jan 1, and Dec 31, 2010, and were aged 15 years or older the time of diagnosis were prospectively included. Data on clinical characteristics and direct costs (investigations and outpatient visits, blood tests, treatments, hospitalisations, and surgeries) were collected prospectively using electronic case-report forms. Patient-level costs incorporated procedures leading to the initial diagnosis of IBD and costs of IBD management during the 5-year follow-up period. Costs incurred by comorbidities and unrelated to IBD were excluded. We grouped direct costs into the following five categories: investigations (including outpatient visits and blood tests), conventional medical treatment, biological therapy, hospitalisation, and surgery. FINDINGS: The study population consisted of 1289 patients with IBD, with 1073 (83%) patients from western Europe and 216 (17%) from eastern Europe. 488 (38%) patients had Crohn's disease, 717 (56%) had ulcerative colitis, and 84 (6%) had IBD unclassified. The mean cost per patient-year during follow-up for patients with IBD was €2609 (SD 7389; median €446 [IQR 164-1849]). The mean cost per patient-year during follow-up was €3542 (8058; median €717 [214-3512]) for patients with Crohn's disease, €2088 (7058; median €408 [133-1161]) for patients with ulcerative colitis, and €1609 (5010; median €415 [92-1228]) for patients with IBD unclassified (p<0·0001). Costs were highest in the first year and then decreased significantly during follow-up. Hospitalisations and diagnostic procedures accounted for more than 50% of costs during the first year. However, in subsequent years there was a steady increase in expenditure on biologicals, which accounted for 73% of costs in Crohn's disease and 48% in ulcerative colitis, in year 5. The mean annual cost per patient-year for biologicals was €866 (SD 3056). The mean yearly costs of biological therapy were higher in patients with Crohn's disease (€1782 [SD 4370]) than in patients with ulcerative colitis (€286 [1427]) or IBD unclassified (€521 [2807]; p<0·0001). INTERPRETATION: Overall direct expenditure on health care decreased over a 5-year follow-up period. This period was characterised by increasing expenditure on biologicals and decreasing expenditure on conventional medical treatments, hospitalisations, and surgeries. In light of the expenditures associated with biological therapy, cost-effective treatment strategies are needed to reduce the economic burden of inflammatory bowel disease.

OBJECTIVE: The Epi-IBD cohort is a prospective population-based inception cohort of unselected patients with inflammatory bowel disease from 29 European centres covering a background population of almost 10 million people. The aim of this study was to assess the 5-year outcome and disease course of patients with Crohn's disease (CD). DESIGN: Patients were followed up prospectively from the time of diagnosis, including collection of their clinical data, demographics, disease activity, medical therapy, surgery, cancers and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis. RESULTS: In total, 488 patients were included in the study. During follow-up, 107 (22%) patients received surgery, while 176 (36%) patients were hospitalised because of CD. A total of 49 (14%) patients diagnosed with non-stricturing, non-penetrating disease progressed to either stricturing and/or penetrating disease. These rates did not differ between patients from Western and Eastern Europe. However, significant geographic differences were noted regarding treatment: more patients in Western Europe received biological therapy (33%) and immunomodulators (66%) than did those in Eastern Europe (14% and 54%, respectively, P<0.01), while more Eastern European patients received 5-aminosalicylates (90% vs 56%, P<0.05). Treatment with immunomodulators reduced the risk of surgery (HR: 0.4, 95% CI 0.2 to 0.6) and hospitalisation (HR: 0.3, 95% CI 0.2 to 0.5). CONCLUSION: Despite patients being treated early and frequently with immunomodulators and biological therapy in Western Europe, 5-year outcomes including surgery and phenotype progression in this cohort were comparable across Western and Eastern Europe. Differences in treatment strategies between Western and Eastern European centres did not affect the disease course. Treatment with immunomodulators reduced the risk of surgery and hospitalisation.

BACKGROUND AND AIM: A definitive diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) is not always possible, and a proportion of patients will be diagnosed as inflammatory bowel disease unclassified (IBDU). The aim of the study was to investigate the prognosis of patients initially diagnosed with IBDU and the disease course during the following 5 years. METHODS: The Epi-IBD study is a prospective population-based cohort of 1289 IBD patients diagnosed in centers across Europe. Clinical data were captured prospectively throughout the follow-up period. RESULTS: Overall, 476 (37%) patients were initially diagnosed with CD, 701 (54%) with UC, and 112 (9%) with IBDU. During follow-up, 28 (25%) IBDU patients were changed diagnoses to either UC (n = 20, 71%) or CD (n = 8, 29%) after a median of 6 months (interquartile range: 4-12), while 84 (7% of the total cohort) remained IBDU. A total of 17 (15%) IBDU patients were hospitalized for their IBD during follow-up, while 8 (7%) patients underwent surgery. Most surgeries (n = 6, 75%) were performed on patients whose diagnosis was later changed to UC; three of these colectomies led to a definitive diagnosis of UC. Most patients (n = 107, 96%) received 5-aminosalicylic acid, while 11 (10%) patients received biologicals, of whom five remained classified as IBDU. CONCLUSIONS: In a population-based inception cohort, 7% of IBD patients were not given a definitive diagnosis of IBD after 5 years of follow-up. One in four patients with IBDU eventually was classified as CD or UC. Overall, the disease course and medication burden in IBDU patients were mild.
