Patients' real-world experience with inflammatory bowel disease: A cross-sectional survey in tertiary care centres from the GETAID group.

BACKGROUND: Patients' experience with healthcare professionals could influence their clinical outcomes. AIMS: To assess inflammatory bowel disease (IBD) patients' experience with their disease, their treatment and their relationship with their physician. METHODS: A one-week cross-sectional study was conducted in 42 IBD centres. 2011 consecutive outpatients with IBD completed an anonymous self-report questionnaire assessing their experience with and knowledge of IBD. RESULTS: A quantitative assessment of the doctor-patient relationship revealed that patients' knowledge of IBD and IBD treatment ranged from 7.4 to 8.3 out of 10. In addition to IBD physicians, other sources of information about IBD and current treatment mainly included the internet (80% and 63%, respectively) and general practitioners (61% and 54%). Knowledge about education programmes (28%) was poor, resulting in a lack of willingness to further use these resources (25%). Concerns about IBD treatment were raised in 76% of patients, mostly related to the fear of adverse events (47%) and a lack of efficacy (33%). The need of alternative healthcare professionals was reported by 89% of the sample. CONCLUSION: In a large cohort of patients, we highlighted gaps in the management of patients with IBD regarding the need for higher-quality information and the implementation of alternative healthcare professionals.

The IBD-disk Is a Reliable Tool to Assess the Daily-life Burden of Patients with Inflammatory Bowel Disease.

BACKGROUND AND AIM: The inflammatory bowel disease [IBD]-disk is a 10-item self-questionnaire that is used to assess IBD-related disability. The aim of the present study was to evaluate this tool in the assessment of IBD daily-life burden. METHODS: A 1-week cross-sectional study was conducted in 42 centres affiliated in France and Belgium. Patients were asked to complete the IBD-disk [best score: 0, worst score: 100] and a visual analogue scale [VAS] of IBD daily-life burden [best score: 0, worst score: 10]. Analyses included internal consistency, correlation analysis, and diagnostic performance assessment. RESULTS: Among the 2011 IBD outpatients who responded to the survey [67.8% of the patients had Crohn's disease], 49.9% were in clinical remission. The IBD-disk completion rate was 73.8%. The final analysis was conducted in this population [n = 1455 patients]. The mean IBD-disk score and IBD daily-life burden VAS were 39.0 ± 23.2 and 5.2 ± 2.9, respectively. The IBD-disk score was well correlated with the IBD daily-life burden VAS [r = 0.67; p <0.001]. At an optimal IBD-disk cut-off of 40, the area under the receiver operating characteristic curve [AUROC] for high IBD daily-life burden [VAS >5] was 0.81 (95% confidence interval [CI]: 0.79-0.83; p <0.001). CONCLUSIONS: In a large cohort of patients, the IBD-disk score was well correlated with IBD daily-life burden, and it could be used in clinical practice.

Forkhead Box F1 represses cell growth and inhibits COL1 and ARPC2 expression in lung fibroblasts in vitro.

Aberrant expression of master phenotype regulators or alterations in their downstream pathways in lung fibroblasts may play a central role in idiopathic pulmonary fibrosis (IPF). Interrogating IPF fibroblast transcriptome datasets, we identified Forkhead Box F1 (FOXF1), a DNA-binding protein required for lung development, as a candidate actor in IPF. Thus we determined FOXF1 expression levels in fibroblasts cultured from normal or IPF lungs in vitro, and explored FOXF1 functions in these cells using transient and stable loss-of-function and gain-of-function models. FOXF1 mRNA and protein were expressed at higher levels in IPF fibroblasts compared with normal fibroblasts (mRNA: +44%, protein: +77%). Immunohistochemistry showed FOXF1 expression in nuclei of bronchial smooth muscle cells, endothelial cells, and lung fibroblasts including fibroblastic foci of IPF lungs. In normal lung fibroblasts, FOXF1 repressed cell growth and expression of collagen-1 (COL1) and actin-related protein 2/3 complex, subunit 2 (ARPC2). ARPC2 knockdown inhibited cell growth and COL1 expression, consistent with FOXF1 acting in part through ARPC2 repression. In IPF fibroblasts, COL1 and ARPC2 repression by FOXF1 was blunted, and FOXF1 did not repress growth. FOXF1 expression was induced by the antifibrotic mediator prostaglandin E2 and repressed by the profibrotic cytokine transforming growth factor-ß1 in both normal and IPF lung fibroblasts. Ex vivo, FOXF1 knockdown conferred CCL-210 lung fibroblasts the ability to implant in uninjured mouse lungs. In conclusion, FOXF1 functions and regulation were consistent with participation in antifibrotic pathways. Alterations of pathways downstream of FOXF1 may participate to fibrogenesis in IPF fibroblasts.
