Future Work

The discovery of a series of genetic and serological markers associated with disease susceptibility and phenotype in inflammatory bowel disease has led to the prospect of an integrated classification system involving clinical, serological and genetic parameters. The Working Party has reviewed current clinical classification systems in Crohn’s disease, ulcerative colitis and indeterminate colitis, and provided recommendations for clinical classification in practice. Progress with respect to integrating serological and genetic markers has been examined in detail, and the implications are discussed. While an integrated system is not proposed for clinical use at present, the introduction of a widely acceptable clinical subclassification is strongly advocated, which would allow detailed correlations among serotype, genotype and clinical phenotype to be examined and confirmed in independent cohorts of patients and, thereby, provide a vital foundation for future work.

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.

Objective. The aim of this study was to evaluate the incidence of inflammatory bowel disease in Kaunas and its region during a 3-year period. Material and Methods. The study was conducted during the 3-year period (2007–2009) and enrolled the patients from Kaunas with its region, which has a population of 381 300 inhabitants. The data were collected from all practices in the area where the diagnosis of inflammatory bowel disease was made by practicing gastroenterologists and consulting pediatricians along with endoscopists. Only new cases of inflammatory bowel disease were included into analysis. The diagnosis of ulcerative colitis and Crohn’s disease was strictly made according to the Copenhagen criteria. Age- and sex-standardized incidence was calculated for each year of the study period. Results. A total of 108 new inflammatory bowel disease cases were diagnosed during the study period: 87 had ulcerative colitis, 16 Crohn’s disease, and 5 indeterminate colitis. The incidence of ulcerative colitis, Crohn’s disease, and indeterminate colitis for each study year was 6.85, 5.33, and 7.38 per 100 000; 0.95, 1.11, and 1.57 per 100 000; and 0.47, 0.21, and 0.42 per 100 000, respectively. The average 3-year standardized incidence of ulcerative colitis, Crohn’s disease, and indeterminate colitis was 6.52, 1.21, and 0.37 per 100 000, respectively. The mean patients’ age at onset of ulcerative colitis, indeterminate colitis, and Crohn’s disease was 49.95 (SD, 17.03), 49.80 (SD, 17.71), and 34.94 years (SD, 0.37), respectively. Conclusions. The average 3-year incidence of ulcerative colitis in Kaunas region was found to be lower as compared with that in many parts of Central and Western Europe. The incidence of Crohn’s disease was low and very similar to other countries of Eastern Europe. Age at onset of the diseases appeared to be older than that reported in the Western industrialized countries.

The Impact

Abstract Background The presence of serrated lesions (SLs) is an established risk factor for colorectal neoplasia development in the general population. However, the impact of SLs on the colorectal neoplasia risk in inflammatory bowel disease (IBD) patients is unknown. In addition, SLs might have been misclassified in IBD patients in the past, in part due to revisions of classification systems. Presently, SLs are categorised as hyperplastic lesions, sessile SLs, and traditional serrated adenomas. We aimed (1) to compare the colorectal neoplasia risk in IBD patients with SLs vs. IBD patients without SLs, and 2) to study the subclassification of SLs in IBD patients before and after histopathological review by two expert gastrointestinal pathologists. Methods We identified all IBD patients with colonic SLs from 1996 to 2019 in a tertiary referral centre using the local histopathology database. Patients with neoplasia prior to SL diagnosis were excluded. Clinical data from patients’ charts were retrieved until June 2019. A subgroup of 135 SLs was reviewed by two pathologists. The log-rank analysis was used to compare the cumulative (advanced) neoplasia incidence in IBD patients with SL vs. IBD patients without SL undergoing surveillance in the same time period. Patients were censored at the end of surveillance or at colectomy. Results We identified 376 SLs in 204 IBD patients (61.9% ulcerative colitis (UC)). In the original reports, 91.9% was classified as a hyperplastic lesion. After histopathological review, 120/136 (88%) of the SLs were confirmed (16 were no SL). Of the 120 confirmed SLs, 62.2% was classified as a sessile SL, 37.8% as a hyperplastic lesion, and 0.8% as a traditional serrated adenoma. The mean time from IBD diagnosis to the first serrated lesion was 14.3 ( ± 12.3) years. A total of 41/204 (20.0%) of patients developed neoplasia (3 CRC, 3 HGD, and 35 LGD; including 2 HGD and 17 LGD at the moment of serrated lesion detection). In the 304 patients without SL (52.6% UC), 63 developed neoplasia (20.7%; 8 CRC, 5 HGD and 50 LGD). Patients who received follow-up colonoscopies after SL (n = 127) had an increased cumulative risk of neoplasia (p < 0.01), but no increased risk of advanced neoplasia (p = 0.50) compared with the group of IBD patients without SL (Figure 1). Conclusion The presence of SLs in IBD patients was associated with a relatively high risk of synchronous colorectal neoplasia as well as an increased risk of subsequent neoplasia, although not with an increased risk of advanced neoplasia. Histopathological review confirmed the SL diagnosis in the majority of lesions, although a large proportion of the hyperplastic lesions was reclassified as a sessile SL.

Background. Because of the chronic and relapsing nature of inflammatory bowel disease (IBD), which often requires characterization with CT scan, IBD patients might be exposed to a large amount of radiation. As a cumulative effective dose (CED) ≥ 100 mSv is considered significant for stochastic risks of cancer, it is important to monitor and control the radiation exposure of the IBD patients. In the present work, we aimed to quantify the mean CED in IBD patients to assess any harmful effects of radiation. Methods. This study includes 200 IBD patients, identified retrospectively, from the outpatient clinics of the Centre Hospitalier de l’Université de Montréal between January 1, 2010, and February 15, 2017, from the gastroenterologists’ patients lists. The number and type of each radiology test performed were listed for each patient during the study period and the CED was calculated using our institution’s dose index when available and standardized tables. Results. Among the 200 IBD patients, 157 patients had Crohn’s disease (CD), 41 had ulcerative colitis (UC), and 2 had indeterminate colitis. The mean CED for IBD patients was 23.1 ± 45.2 mSv during a mean follow-up duration of 4.3 years. CED was higher among patients with CD than with UC (27.5 ± 49.5 versus 6.8 ± 14.8 mSv; p<0.01). Six patients were exposed to a high CED (>100 mSv) and all had CD. Conclusion. While potentially harmful levels of radiation exposure are of concern in only a small number of patients, strategies to limit such exposure are encouraged when clinically appropriate.
