Résumé
Abstract Background Emerging data suggest that a treat-to-target approach and early therapeutic intervention using regular objective disease assessment leads to improved outcomes. Our aim was to evaluate the value of objective disease monitoring during regular follow-up. Methods Patients presenting in our IBD center between January and December in, 2018 were included and followed up for, 1 year. Data from clinical visits, clinical disease activity using Crohn’s Disease Activity Index and partial Mayo Score, biomarkers (CBC, CRP, FCAL), stool culture, colonoscopy/sigmoidoscopy, CT/MRI scans, abdominal US, total number of visits, hospitalization or surgery rates, and change in medical therapy were collected. We compared monitoring strategy according to the clinical disease activity in the given quarter-year period based on the patient’s status of clinical disease activity (remission/ flare / post-flare/ continuous activity). Results N=161 patients were included (CD:118/UC:43; male:, 56%), with predominantly moderate-to-severe disease phenotype (70% on biological therapy). In total, n=644 quarter year periods (n=, 554 with patient visit) were evaluated (remission, 57%; continuous activity, 19%; post-flare, 11%; flare, 13%). CBC and CRP were performed in, 82.9% and, 83.9% of all patients with at least one clinical visit in a quarter-year period, regardless of clinical activity in IBD. Colonoscopy was performed in patients with flare or continuous disease activity in, 21.1% and, 18.9%, but, 10.1% of the patients in clinical remission also underwent colonoscopy in a given quarter-year period. In a sub-analysis of UC patients, 24.1% of the patients presenting with disease flare had colonoscopy in a given period. Stool culture and C.difficile stool tests were performed in, 17.2% of UC patients with flare. CT scans were performed at a low rate of, 2.4% in CD patients with disease flare, while MRI scans were similar in all subgroups of CD patients (7.7–16.7%)., 13.2% of patients with cont. activity and, 24.5% of patients with flare needed initiation or dose optimization of corticosteroids, while biological start or dose optimization was needed in, 31.1% and, 33.8% in a given quarter-year period. Mean number of follow-up visits per quarter-year period was high(1.6) even for patients in remission, and, 2.4 in flare. Conclusion Our study confirmed the use of regular objective biomarker monitoring, independent of clinical activity. We report high utilization of c-scope/sigmoidoscopy as well as MRI (in CD) in the objective evaluation of patients with clinical symptoms or even as part of routine monitoring. CT was reserved for emergency situations, while the use of US was relatively low. Objective monitoring resulted in frequent and early optimization of the therapeutic strategy.

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.
