Abstract
En 中文
Background: Patients with Crohn's disease (CD) are at risk of progressing from inflammatory to stricturing and penetrating phenotypes. The influence of the depth of remission on the risk of progression has not been adequately evaluated. Methods: A retrospective cohort study including surgically na & iuml;ve CD patients with inflammatory phenotype evaluated concomitantly by magnetic resonance enterography and colonoscopy. The degree of remission was correlated with the risk of progressing to stricturing and penetrating phenotypes. Results: Three hundred nineteen CD patients were included: 27.0% with transmural remission, 16.0% with isolated endoscopic remission, 14.4% with isolated radiologic remission, and 42.6% without remission. Patients with transmural remission presented the lowest rates of phenotype progression (1.2%), with a significant difference compared to isolated radiologic remission (10.9%, p = 0.019), to isolated endoscopic remission (19.6%, p <= 0.001), and to no remission (46.3%, p <= 0.001). In multivariate regression analysis, transmural remission (OR 0.017 95% CI 0.002-0.135, p < 0.001), isolated radiologic remission (OR 0.139 95% CI 0.049-0.396, p < 0.001), and isolated endoscopic remission (OR 0.301 95% CI 0.123-0.736, p = 0.008) resulted in lower rates of phenotype progression compared to no remission. No patient with transmural or isolated radiologic remission progressed to penetrating phenotypes. Conclusion: The degree of bowel remission correlates with the risk of phenotype progression. Patients with transmural remission are at the lowest risk of progressing to stricturing and penetrating phenotypes.
