Abstract

International audience; Background The identification of patients at high risk of a disabling disease course would be invaluable in guiding initial therapy in Crohn’s disease (CD). Our objective was to evaluate a combination of clinical, serological, and genetic factors to predict complicated disease course in pediatric-onset CD. Methods Data for pediatric-onset CD patients, diagnosed before 17 years of age between 1988 and 2004 and followed more than 5 years, were extracted from the population-based EPIMAD registry. The main outcome was defined by the occurrence of complicated behavior (stricturing or penetrating) and/or intestinal resection within the 5 years following diagnosis. Lasso logistic regression models were used to build a predictive model based on clinical data at diagnosis, serological data (ASCA, pANCA, anti-OmpC, anti-Cbir1, anti-Fla2, anti-Flax), and 369 candidate single nucleotide polymorphisms. Results In total, 156 children with an inflammatory (B1) disease at diagnosis were included. Among them, 35% (n = 54) progressed to a complicated behavior or an intestinal resection within the 5 years following diagnosis. The best predictive model (PREDICT-EPIMAD) included the location at diagnosis, pANCA, and 6 single nucleotide polymorphisms. This model showed good discrimination and good calibration, with an area under the curve of 0.80 after correction for optimism bias (sensitivity, 79%, specificity, 74%, positive predictive value, 61%, negative predictive value, 87%). Decision curve analysis confirmed the clinical utility of the model. Conclusions A combination of clinical, serotypic, and genotypic variables can predict disease progression in this population-based pediatric-onset CD cohort. Independent validation is needed before it can be used in clinical practice.

Abstract

Background and Aims Defining and assessing the reproducibility of Crohn's disease [CD] endoscopic lesions is essential in assessing endoscopic healing. Methods Twelve endoscopic CD experts from the GETAID defined aphthoid erosions [AE], superficial ulcerations [SU], deep ulcerations [DU], stenosis, and fistulas according to a Delphi-like method. Thirty different GETAID physicians declared if they found acceptable each definition. Intra- and inter-observer agreements were investigated using 100 videos with one tagged specific lesion [AE, SU, DU, or sham lesion] read by 15 independent endoscopists at baseline and 1 month later in a randomised order. Video quality was determined by an external reader. According to kappa estimate [κ ±standard error], intra or inter-observer agreement was qualified as 'moderate' [0.4–0.6], 'substantial' [0.6–0.8], or 'almost perfect' [0.8–1.0]. Results Among 30 different experts, 83% to 97% found acceptable the definitions retrieved from the Delphi-like method. Intra-observer κ was 0.717 [±0.019] for SU, 0.681 [±0.027] for AE, 0.856 [±0.014] for DU, showing 'substantial' agreement. It was 0.801 [±0.016] for any ulceration [DU or SU]. There was a high variability across readers from 'moderate' to 'almost perfect' agreement. Inter-observer κ was 0.548 [±0.042] for SU, 0.554 [±0.028] for AE 0.694 [±0.041] for DU, and 0.705 [±0.042] for any ulceration. Inter-observer agreement increased when reading the 53 high-quality videos: 0.787 [±0.064] [ p  = 0.001], 0.607 [±0.043] [ p  = 0.001], and 0.782 [±0.064][ p  = 0.001] for DU, AE, and any ulceration, respectively. Conclusions Despite variable intra-agreement level across readers, the GETAID definitions for CD endoscopic lesions provided 'substantial' inter-observer agreements, especially in case of high-quality videos.

Abstract

Background: Crohn's disease (CD)-associated dysbiosis could predispose patients to relapse. Gut microbiota composition of patients from the prospective cohort study designed to identify predictive factors of clinical relapse after infliximab discontinuation (STORI Study) was investigated to determine the impact of dysbiosis in CD relapse., Methods: Fecal samples from 33 patients with CD in this cohort were collected at baseline, 2 months, 6 months, and at the end of the follow-up period (19 relapsers and 14 nonrelapsers). Healthy volunteers subjects (n = 29) were used as a control group. The fecal microbiota composition was assessed using quantitative PCR, and comparisons between the patient groups were made at different time points using the Wilcoxon test. The analysis of the time-to-relapse was performed according to the baseline median level of each bacterial signal., Results: Dysbiosis was observed in patients with CD compared with healthy subjects, and it was characterized by low mean counts of Firmicutes (Clostridium coccoides [P = 0.0003], C. leptum [P < 0.0001], and Faecalibacterium prausnitzii [P = 0.003]). Lower rates of Firmicutes were seen in relapsers compared with nonrelapsers. Moreover, a low rate of F. prausnitzii (P = 0.014) and a low rate of Bacteroides (P = 0.030) predicted relapse independently from high C reactive protein level (P = 0.0001)., Conclusions: In this work, we report that CD-associated dysbiosis, characterized by a decrease in Firmicutes, correlates with the time-to-relapse after infliximab withdrawal. A deficit in some bacterial groups or species, such as F. prausnitzii, may represent a predictive factor for relapse. Restoring normobiosis in CD could be a new goal for optimal CD management.

Abstract

Background: The role of small bowel capsule endoscopy in the management of established Crohn's disease is uncertain., Methods: A retrospective study of small bowel capsule endoscopy tests performed in a referral centre from 2008 to 2011; 77 tests were performed in patients with known Crohn's disease. Six patients were excluded due to capsule test retention. Patients were classified into 4 indication groups: unexplained anaemia (G1, n = 6); discrepancy between clinical symptoms and morphology (G2, n = 25), full assessment of Crohn's disease location (G3, n = 37) and evaluation of mucosal healing (G4, n = 3)., Results: Twenty-seven (38%) patients had no lesions, 32 (45%) moderate and 12 (17%) severe lesions. Endoscopic lesions were found in 4/6 (67%) G1 patients, 11/25 (44%) G2 and 28/37 (76%) G3 (p < 0.03). Three months after endoscopy was performed, 38/71 patients experienced a change in their treatment that was significantly associated with the severity of endoscopic lesions and with test indications; in 60%, 20% and 58% of patients from G1, G2 and G3, respectively (p < 0.01)., Conclusion: Small bowel capsule endoscopy resulted in management changes in the majority of patients with established Crohn's disease., (Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l.
