Abstract Background Patients with colon Inflammatory Bowel Disease (IBD) have a higher risk of colorectal cancer (CRC) than general population. Current guidelines establish endoscopic surveillance recommendations; however, epidemiological studies show poor compliance. The main aim of our study was to analyse adherence to endoscopic surveillance guidelines. Secondary aim was to evaluate the prevalence and time-to advanced lesions or CRC. Methods Retrospective multicentre study of patients with IBD followed-up in the participating centres between 2005 and 2020, who were diagnosed of IBD between 2005 and 2008, with criteria for CRC surveillance. Patients with CRC before IBD diagnosis were excluded. The ECCO 2013–2017 guidelines were used to evaluate adherence. Adenomatous lesions with >25% of villous component, >1cm or with high-grade dysplasia or serrated lesions >1cm or with any degree of dysplasia were considered advanced lesions. Software used for all analysis was R in its 3.6.1 version. Normality was checked with the Shapiro-Wilks test. Mean comparison was carried out using t-Student test while normality assumptions held true, otherwise, Mann-Whitney test. Time-to advanced lesions or CRC event between patients that had adherence to ECCO guidelines versus those who did not was performed through Kaplan-Meier and Log-rank test. P-values below 0.05 were considered significant. Results A total of 1004 (713 Ulcerative Colitis, 252 Crohn’s disease and 39 Indeterminate Colitis; 52% male) patients from 25 centres were recruited with a median age of 36 (26–47) years. 87% of all patients were included in the endoscopic surveillance programme. The main reasons for non-inclusion were the absence of indication by the physician (38%) and the presence of inflammatory activity (37%). Adherence to the first or subsequent surveillance colonoscopies was 45% and 61%, respectively, with a total adherence rate of 32%. Prevalence of advanced lesions or CRC was 4% and 7 cases of CRC were detected. Time-to-detection of these lesions since IBD diagnosis was significantly longer in non-adherent patients (13.4 + 1.3 vs13.04 + 1.7; p<0.001). Adherence was associated to a higher detection of advanced lesions or CRC compared to non-adherent patients (HR: 1.97; IC: 1.02–3.79; p=0.043) (Figure 1). Conclusion Adherence to ECCO guidelines for endoscopic surveillance is low in this Southern European population. A higher and earlier detection of advanced lesions or CRC was identified in the adherent group. The results of this study highlight the need to improve compliance with the recommendations to obtain better outcomes.

BackgroundPatients with inflammatory bowel disease (IBD) have increased risk of developing colorectal cancer (CRC), depending on the duration and severity of the disease. The evolutionary process in IBD is driven by chronic inflammation leading to epithelial-to-mesenchymal transition (EMT) events in colonic fibrotic areas. EMT plays a determinant role in tumor formation and progression, through the acquisition of ‘stemness’ properties and the generation of neoplastic cells. The aim of this study is to monitor EMT/cancer initiating tracts in IBD in association with the deep characterization of inflammation in order to assess the mechanisms of IBD severity and progression towards malignancy.Methods10 pediatric and 20 adult IBD patients, admitted at Sidra Medicine (SM) and Hamad Medical Corporation (HMC) respectively, have been enrolled in this study, from whom gut tissue biopsies (from both left and right side) were collected. Retrospectively collected tissues (N=10) from patients with malignancy and history of IBD were included in the study. DNA and RNA were extracted from fresh small size (2–4 mm in diameter) gut tissues using the BioMasher II (Kimble) and All Prep DNA/RNA kits (Qiagen). MicroRNA (miRNA; N=700) and gene expression (N=800) profiling have been performed (cCounter platform; Nanostring) as well as the methylation profiling microarray (Infinium Methylation Epic Bead Chip kit, Illumina) to interrogate up to 850,000 methylation sites across the genome.ResultsDifferential miRNA profile (N=27 miRNA; p<0.05) was found by the comparison of tissues from pediatric and adult patients. These miRNAs regulate: i. oxidative stress damage (e.g., miR 99b), ii. hypoxia induced autophagy; iii. genes associated with the susceptibility to IBD (ATG16L1, NOD2, IRGM), iv. immune responses, such as TH17 T cell subset (miR 29). N=6 miRNAs (miR135b, 10a196b, 125b, let7c, 375) linked with the regulation of Wnt/b-catenin, EM-transaction, autophagy, oxidative stress and play role also in cell proliferation and mobilization and colorectal cancer development were differentially expressed (p<0.05) in tissues from left and right sides of gut. Gene expression signature, including genes associated with inflammation, stemness and fibrosis, has also been performed for the IBD tissues mentioned above. Methylation sites at single nucleotide resolution have been analyzed.ConclusionsAlthough the results warrant further investigation, differential genomic profiling suggestive of altered pathways involved in oxidative stress, EMT, and of the possible stemness signature was found. The integration of data from multiple platforms will provide insights of the overall molecular determinants in IBD patients along with the evolution of the disease.Ethics ApprovalThis study was approved by Sidra Medicine and Hamad Medical Corporation Ethics Boards; approval number 180402817 and MRC-02-18-096, respectively.

Inflammatory Bowel

Abstract Background Inflammatory bowel disease (IBD) is a debilitating intestinal condition, manifesting as Crohn’s disease (CD), ulcerative colitis (UC) or indeterminate colitis (IC). The patient experience is impacted by a lack of awareness from other stakeholders despite growing global disease prevalence. To gain deeper insight of the patient experience, promote quality care, and enhance quality of life, we performed a qualitative study of the patient journey starting from pre-diagnosis through treatment. Methods U.S. patients with IBD were recruited via UC/CD support groups and organizations, social media platforms, blog followers, and personal networks. Participants were screened via an emailed survey and asked to self-identify as medically diagnosed on the basis of reported diagnostic testing. Interviews were conducted by qualitative researchers by phone or web conferencing. Open-ended questions were developed to support and gather information about our learning objectives—primarily, our desire to understand the unique experiences of UC/CD patients in their journey from symptom onset through diagnosis, treatment and maintenance (e.g. “Upon diagnosis, what were your immediate thoughts about the condition?”). This qualitative data were analyzed using Human-Centered Design methodology, including patient typologies (personas), forced temporal zoom (journey maps), forced semantic zoom (stakeholder system mapping), and affinity mapping for pattern recognition of unmet needs. Results A total of 32 patients were interviewed: N=17 CD patients, N=13 UC patients and N=2 IC patients. The interviewed population reflected regional, demographic, and disease-related diversity (Table 1). Five unique, mutually exclusive journeys were identified to understand and classify patient experiences: (1) Journey of Independence, (2) Journey of Acceptance, (3) Journey of Recognition, (4) Journey of Passion and (5) Journey of Determination (Figure 1). Patients with IBD expressed a need for increased awareness, education, and training for providers to shorten the path to diagnosis. Mental health support was found to be a critical gap in care, particularly for major treatment decisions (e.g., surgery). The inclusion of emotional support into the treatment paradigm was perceived as essential to long-term wellness. Patient attitudes and self-advocacy varied on their individual journeys; understanding these journeys may accelerate time to diagnosis and treatment. Conclusion Better understanding of patient journeys can help healthcare providers improve their approach to patient care and coordination.
