P640 Incidence, prevalence, disease phenotype and maximal therapeutic step in Crohn’s disease patients in Western Hungary – a population-based study between 2007–2018, data from the Veszprem county cohort
Notice bibliographique
Résumé
Abstract Background The number of epidemiological population-based studies are still limited from Eastern Europe. The present study is a continuation of the Veszprem IBD population based cohort with a follow-up of the incidence and disease course of IBD since 1977. Our aim was to analyze the incidence and disease phenotype at diagnosis, and the maximal therapeutic step distributions during follow-up in a prospective population-based database from Veszprem Province, including incident Crohn’s disease (CD) patients diagnosed between January 1, 2007 and December 31, 2018. Methods Data of 421 incident CD patients were analyzed (male/female: 237/184; median age at diagnosis: 29 years(y) [IQR: 21–42]). Both in-hospital and outpatient records were collected and comprehensively reviewed at diagnosis and during clinical follow-up. The source of age- and gender-specific demographic data was derived from the national population census in 2011. Results Adjusted mean incidence rate was 9.94(CI95%: 9.0–10.9)/105 person-years in this 12 year period[males:11.5(CI95%:10.2–13.2)/105; females:8.4(CI95%:7.3–9.7)/105]. Prevalence rate was 191.18(CI95%:177.0–205.7)/105 persons in 2011 and 236.78(CI95%:220.8–252.8) in 2015. For detailed annual incidence rates and age-specific mean incidence rates see Figure1 and 2. Peak onset age in CD was 20–29 years of age. Diagnostic delay from symptom onset was ≥1year in 26.6%, and ≥3 years in 10% of the patients. Disease location was ileal(L1) in 29.7%, colonic(L2) in 24.5%, and ileo-colonic(L3) in 45.8% at diagnosis. Upper gastrointestinal manifestation or perianal disease were present in 7.6% and 13.5%. Disease behavior at diagnosis was luminal(B1) in 62.5%, stenosing(B2) in 17.6%, penetrating(B3) in 16.4%, and B2+B3 in 3.6%. Patients with ileocolonic disease were younger (29.2y,SD:14.6) at diagnosis compared to patients with ileal(35.7y,SD:15.5;p<0.001) or colonic disease(37.7y;SD:18.1;p<0.001). Extraintestinal manifestations were as follows: hepatic5.0%(PSC 1.9%), arthritis13.8%, ocular1.7%, cutan4.3%. Active smokers at diagnosis were 35.4%. Distribution of maximal therapeutic steps during the course of follow-up (8.53y,SD: 3.3) were 5-ASA in 15.7%, systemic corticosteroids in 14.3%, immunosuppressive therapy in 42.5%; anti-TNF biologic therapy in 23.3% and other biologic therapy in 2.9%. Conclusion The incidence of CD in this 12 year period was high, comparable to high-incidence areas in Western European countries, and comparable to previous data from the Veszprem cohort, while prevalence rates continue to rise.(Lakatos 2011, IBD). Ileocolonic location and penetrating disease behavior were somewhat higher compared to previous population-based data from Western Europe.(Burisch 2018, JCC).

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
