- Background and Aims: Diagnosis and management of inflammatory bowel diseases [IBD] requires a lifelong multidisciplinary approach.The quality of medical reporting is crucial in this context.The present topical review addresses the need for optimised reporting in endoscopy, surgery, and histopathology. Methods: A consensus expert panel consisting of gastroenterologists, surgeons, and pathologists, convened by the European Crohns and Colitis Organisation, performed a systematic literature review. The following topics were covered: in endoscopy: [i] general IBD endoscopy; [ii] disease activity and surveillance; [iii] endoscopy treatment in IBD; in surgery: [iv] medical history with surgical relevance, surgical indication, and strategy; [v] operative approach; [vi] intraoperative disease description; [vii] operative steps; in pathology: [viii] macroscopic assessment and interpretation of resection specimens; [ix] IBD histology, including biopsies, surgical resections, and neoplasia; [x] IBD histology conclusion and report. Statements were developed using a Delphi methodology incorporating two consecutive rounds. Current practice positions were set when >= 80% of participants agreed on a recommendation. Results: Thirty practice positions established a standard terminology for optimal reporting in endoscopy, surgery, and histopathology. Assessment of disease activity, surveillance recommendations, advice to surgeons for operative indication and strategies, including margins and extent of resection, and diagnostic criteria of IBD, as well as guidance for the interpretation of dysplasia and cancer, were handled. A standardised report including a core set of items to include in each specialty report, was defined. Conclusions: Interdisciplinary high-quality care requires thorough and standardised reporting across specialties.This topical review offers an actionable framework and practice recommendations to optimise reporting in endoscopy, surgery, and histopathology.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: Inflammatory bowel disease may cause long-standing inflammation and fibrosis and may increase the risk of adverse events in colonoscopy. We evaluated whether inflammatory bowel disease and other potential risk factors are associated with bleeding or perforation in a nationwide, population-based, Swedish study.Methods: Data from 969 532 colonoscopies, including 164 012 [17%] on inflammatory bowel disease patients, between 2003 and 2019, were retrieved from the National Patient Registers. ICD-10 codes for bleeding [T810] and perforation [T812] within 30 days of the colonoscopy were recorded. Multivariable logistic regression was used to test if inflammatory bowel disease status, inpatient setting, time period, general anaesthesia, age, sex, endoscopic procedures, and antithrombotic treatment were associated with higher odds for bleeding and perforation.Results: Bleeding and perforation were reported in 0.19% and 0.11% of all colonoscopies, respectively. Bleeding [odds ratio 0.66, p <0.001] and perforation [odds ratio 0.79, p <0.033] were less likely in colonoscopies in individuals with inflammatory bowel disease status. Bleeding and perforation were more common in inpatient than in outpatient inflammatory bowel disease colonoscopies. The odds for bleeding but not perforation increased between 2003 to 2019. General anaesthesia was associated with double the odds for perforation.Conclusions: Individuals with inflammatory bowel disease did not have more adverse events compared with individuals without inflammatory bowel disease status. However, the inpatient setting was associated with more adverse events, particularly in inflammatory bowel disease status. General anaesthesia was associated with a greater risk of perforation.

- Background and Aims: An adaptive immunological response to microbial antigens has been observed in Crohn's disease (CD). Intriguingly, this serological response precedes the diagnosis in some patients and has also been observed in healthy relatives. We aimed to determine whether genetic factors are implicated in this response in a CD twin cohort.Methods: In total, 82 twin pairs (Leuven n = 13, Maastricht n = 8, Örebro n = 61) took part: 81 pairs with CD (concordant monozygotic n = 16, discordant monozygotic n = 22, concordant dizygotic n = 3, discordant dizygotic n = 40) and 1 monozygotic pair with both CD and ulcerative colitis. Serology for Pseudomonas fluorescens-related protein (anti-I2), Escherichia coli outer membrane porin C (anti-OmpC), CBir1flagellin (anti-CBir1) and antibodies to oligomannan (anti-Saccharomyces cerevisiae antibody [ASCA]) was determined by standardized enzyme-linked immunoassay.Results: All markers were more often present in CD twins than in their healthy twin siblings. Using the intraclass correlation coefficient (ICC), agreements in concentrations of anti-OmpC and anti-I2 were observed in discordant monozygotic but not in discordant dizygotic twin pairs with CD (anti-OmpC, ICC 0.80 and -0.02, respectively) and (anti-I2, ICC 0.56 and 0.05, respectively). In contrast, no agreements were found in anti-CBir, immunoglobulin (Ig) G ASCA and ASCA IgA.Conclusions: We show that anti-I2 and anti-CBir1 statuses have specificity for CD and confirm previous reported specificities for anti-OmpC and ASCA. Based on quantitative analyses and observed ICCs, genetics seems to predispose to the anti-OmpC and anti-I2 response but less to ASCA and anti-CBir1 responses.

Fibre intake and the development of inflammatory bowel disease : A European prospective multi-centre cohort study (EPIC-IBD)
- 2018
-

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: Population-based prospective cohort studies investigating fibre intake and development of inflammatory bowel disease are lacking. Our aim was to investigate the association between fibre intake and the development of Crohn's disease [CD] and ulcerative colitis [UC] in a large European population.Methods: In total, 401 326 participants, aged 20-80 years, were recruited in eight countries in Europe between 1991 and 1998. At baseline, fibre intake [total fibres, fibres from fruit, vegetables and cereals] was recorded using food frequency questionnaires. The cohort was monitored for the development of inflammatory bowel disease. Each case was matched with four controls and odds ratios [ORs] for the exposures were calculated using conditional logistic regression. Sensitivity analyses according to smoking status were computed.Results: In total, 104 and 221 participants developed incident CD and UC, respectively. For both CD and UC, there were no statistically significant associations with either quartiles, or trends across quartiles, for total fibre or any of the individual sources. The associations were not affected by adjusting for smoking and energy intake. Stratification according to smoking status showed null findings apart from an inverse association with cereal fibre and CD in non-smokers [Quartile 4 vs 1 OR = 0.12, 95% confidence interval = 0.02-0.75, p = 0.023, OR trend across quartiles = 0.50, 95% confidence interval = 0.29-0.86, p = 0.017].Conclusion: The results do not support the hypothesis that dietary fibre is involved in the aetiology of UC, although future work should investigate whether there may be a protective effect of specific types of fibre according to smoking status in CD.

Ileorectal anastomosis in comparison with ileal pouch anal anastomosis in reconstructive surgery for ulcerative colitis - a single institution experience
- 2014
-
Ingår i: Journal of Crohn's & Colitis. - : Elsevier. - 1873-9946 .- 1876-4479. ; 8:7, s. 582-589

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION:Ileal pouch anal anastomosis (IPAA) is the standard procedure for reconstruction after colectomy for ulcerative colitis (UC). However, ileorectal anastomosis (IRA) as an alternative has, recently experienced a revival. This study from a single center compares the clinical outcomes of these procedures.METHODS:From 1992 to 2006, 253 patients consecutively underwent either IRA (n=105) or IPAA (n=148). Selection to either procedure was determined on the basis of rectal inflammation, presence of dysplasia/cancer or patient preferences. Patient-records were retrospectively evaluated. Mean follow-up time was 5.4 and 6.3 years respectively.RESULTS:Major postoperative complications occurred in 12.4% of patients after IRA and in 12.8% after IPAA (ns). Complications of any kind after IRA or IPAA, even including subsequent stoma-closure, occurred in 23.8% and 39.9% respectively (p<0.01). Estimated cumulative failure rates after 5 and 10 years were 10.1% and 24.1% for IRA and 6.1% and 18.6% for IPAA respectively (ns). The most common cause for failure was intractable proctitis (4.8%) and unspecified dysfunction (4.8%) respectively. At follow-up 76.9% of patients with IRA had proctitis and 34.1% with IPAA had pouchitis. Estimated cumulative cancer-risk after 10, 20 and 25 year duration of disease was 0.0%, 2.1% and 8.7% for IRA. Figures for IPAA were 0.7%, 1.8% and 1.8% (ns).CONCLUSION:Failure-rates did not significantly differ between patients operated with IRA or IPAA. Patients operated with IPAA had a higher cumulative number of postoperative complications. The high long-term cancer-risk after IRA indicates that this procedure should be an interim solution in younger patients.

Inflammatory Bowel Disease and Risk of Colorectal Polyps : A nationwide population-based cohort study from Sweden
- 2023
-
Ingår i: Journal of Crohn's & Colitis. - : Oxford University Press. - 1873-9946 .- 1876-4479. ; 17:9, s. 1395-1409

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Inflammatory bowel disease (IBD) has been linked to an increased risk of colorectal neoplasia. However, the types and risks of specific polyp types in IBD are less clear.METHODS: We identified 41,880 individuals with IBD [Crohn's disease (CD: n=12,850); Ulcerative colitis (UC): n=29,030)] from Sweden matched with 41,880 reference individuals. Using Cox regression, we calculated adjusted hazard ratios (aHRs) for neoplastic colorectal polyps (Tubular, Serrated/Sessile, Advanced and Villous) defined by histopathology codes.RESULTS: During follow-up, 1648 (3.9%) IBD patients and 1143 (2.7%) reference individuals had an incident neoplastic colorectal polyp, corresponding to an incidence rate of 46.1 and 34.2 per 10,000 person-years, respectively. This correlated to an aHR of 1.23 (95% CI 1.12-1.35) with the highest HRs seen for sessile serrated polyps (8.50, 95% CI 1.10-65.90) and traditional serrated adenomas (1.72, 95% CI 1.02-2.91). aHRs for colorectal polyps were particularly elevated in those diagnosed with IBD at a young age and after 10 years after diagnosis. Both absolute and relative risks of colorectal polyps were higher in UC than in CD (aHRs 1.31 vs. 1.06, respectively), with a 20-year cumulative risk differences of 4.4% in UC and 1.5% in CD, corresponding to one extra polyp in 23 patients with UC and one in 67 CD patients during the first 20 years after IBD diagnosis.CONCLUSIONS: In this nationwide population-based study, there was an increased risk of neoplastic colorectal polyps in IBD patients. Colonoscopic surveillance in IBD appears important, especially in UC and after 10 years of disease.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: The association between microscopic colitis [MC] and cancer risk is unclear. Large, population-based studies are lacking.Methods: We conducted a nationwide cohort study of 11 758 patients with incident MC [diagnosed 1990-2016 in Sweden], 50 828 matched reference individuals, and 11 614 siblings to MC patients. Data were obtained through Sweden's pathology departments and from the Swedish Cancer Register. Adjusted hazard ratios [aHRs] were calculated using Cox proportional hazards models.Results: At the end of follow-up [mean: 6.7 years], 1239 [10.5%] of MC patients had received a cancer diagnosis, compared with 4815 [9.5%] of reference individuals (aHR 1.08 [95% confidence interval1.02-1.16]). The risk of cancer was highest during the first year of follow up. The absolute excess risks for cancer at 5, 10, and 20 years after MC diagnosis were + 1.0% (95% confidence interval [C1]0.4%-1.6%), +1.5% [0.4%-2.6%], and + 3.7% [-2.3-9.6%], respectively, equivalent to one extra cancer event in every 55 individuals with MC followed for 10 years. MC was associated with an increased risk of lymphoma (aHR 1.43 [1.06-1.92]) and lung cancer (aHR 1.32 [1.04-1.68]) but with decreased risks of colorectal (aHR 0.52 [0.40-0.66]) and gastrointestinal cancers (aHR 0.72 [0.60-0.85]). We found no association with breast or bladder cancer. Using siblings as reference group to minimise the impact of shared genetic and early environmental factors, patients with MC were still at an increased risk of cancer (HR 1.20 [1.06-1.36]).Conclusions: This nationwide cohort study demonstrated an 8% increased risk of cancer in MC patients. The risk was highest during the first year of follow-up.

The Cost-effectiveness of Biological Therapy Cycles in the Management of Crohn's Disease
- 2019
-
Ingår i: Journal of Crohn's & Colitis. - : Oxford University Press (OUP). - 1873-9946 .- 1876-4479. ; 13:10, s. 1323-1333

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To examine the cost-effectiveness of continued treatment for patients with moderate-severe Crohn's disease in clinical remission, with a combination of anti-tumour necrosis factor alpha [anti-TNFα] [infliximab] and immunomodulator therapy compared with two different withdrawal strategies: [1] withdrawal of the anti-TNFα therapy; and [2] withdrawal of the immunomodulator therapy, respectively. METHODS: A decision-tree model was constructed mimicking three treatment arms: [1] continued combination therapy with infliximab and immunomodulator; [2] withdrawal of infliximab; or [3] withdrawal of the immunomodulator. Relapses in each arm are managed with treatment intensification and re-institution of the de-escalated drug according to a prespecified algorithm. State-dependent relapse risks, remission probabilities, and quality of life weights were collected from previous published studies. RESULTS: Combination therapy was less costly and more efficient than the withdrawal of the immunomodulator, and more costly and more efficient than withdrawal of infliximab. Whether or not combination therapy is cost-effective, compared with the alternatives, depends primarily on current pharmaceutical prices and the willingness-to-pay per additional quality-adjusted life-year [QALY]. CONCLUSIONS: Combination therapy using a combination of anti-TNFα [infliximab] and an immunomodulator is cost-effective in the treatment of Crohn's disease compared with treatment cycles in which the immunomodulator is withdrawn. Combination treatment is cost-effective compared with treatment cycles in which infliximab is withdrawn, at prices of infliximab below€192/100 mg, given a willingness-to-pay threshold at€49 020 [Sweden] per additional QALY.

In-Depth Study of Transmembrane Mucins in Association with Intestinal Barrier Dysfunction During the Course of T Cell Transfer and DSS-Induced Colitis
- 2020
-
Ingår i: Journal of Crohns & Colitis. - : Oxford University Press (OUP). - 1873-9946. ; 14:7, s. 974-994
-
Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: There is evidence for a disturbed intestinal barrier function in inflammatory bowel diseases [IBD] but the underlying mechanisms are unclear. Because mucins represent the major components of the mucus barrier and disturbed mucin expression is reported in the colon of IBD patients, we studied the association between mucin expression, inflammation and intestinal permeability in experimental colitis. Methods: We quantified 4-kDa FITC-dextran intestinal permeability and the expression of cytokines, mucins, junctional and polarity proteins at dedicated time points in the adoptive T cell transfer and dextran sodium sulfate [DSS]-induced colitis models. Mucin expression was also validated in biopsies from IBD patients. Results: In both animal models, the course of colitis was associated with increased interleukin-1 beta [IL-1 beta] and tumour necrosis factor-alpha [TNF-alpha] expression and increased Muc1 and Muc13 expression. In the T cell transfer model, a gradually increasing Muc1 expression coincided with gradually increasing 4-kDa FITC-dextran intestinal permeability and correlated with enhanced IL-1 beta expression. In the DSS model, Muc13 expression coincided with rapidly increased 4-kDa FITC-dextran intestinal permeability and correlated withTNF-alpha and Muc1 overexpression. Moreover, a significant association was observed between Muc1, Cldn1, Ocln, Par3 and aPKC zeta expression in the T cell transfer model and between Muc13, Cldn1, Jam2, Tjp2, aPkc zeta, Crb3 and Scrib expression in the DSS model. Additionally, MUC1 and MUC13 expression was upregulated in inflamed mucosa of IBD patients. Conclusions: Aberrantly expressed MUC1 and MUC13 might be involved in intestinal barrier dysfunction upon inflammation by affecting junctional and cell polarity proteins, indicating their potential as therapeutic targets in IBD.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Studies from mainly before the wide use of targeted therapies and guidelines for thromboprophylaxis indicate that patients with inflammatory bowel disease (IBD) are at a doubled risk of venous thromboembolism (VTE). We studied the risk of VTE in a modern-day cohort of patients with IBD, overall and in subgroups of disease characteristics.Methods: Using Swedish healthcare registers, we identified a nationwide population-based cohort of 55,252 patients with incident IBD between 2007 and 2021 with a median follow-up time of 6.5 years. Patients were matched by age, sex, calendar year and county of residence with up to ten reference individuals from the general population (N=536,067). The primary outcome was VTE, including pulmonary embolism and deep vein thrombosis. Incidence rates per 1,000 person-years and hazard ratios (HR) were calculated for IBD in general and according to disease subtype, sex, age and disease characteristics at diagnosis. HRs stratified by matching variables (model 1) and additionally adjusted for comorbidities and socioeconomic factors (model 2) were estimated by using Cox regression.Results: The incidence rate of VTE among patients with IBD was 5.03 per 1,000 person-years compared with 2.34 per 1,000 person-years among reference individuals (Table 1). This corresponded to a doubled incidence of VTE (HR=2.18, 95% confidence interval (CI)=2.07-2.29, model 1). Adjusting further for covariates in model 2 had only minor effects on the HR. The HR was consistent across IBD subtypes and sex. The relative risk was higher for those with younger age (18-39 years) at IBD diagnosis (HR 2.52, 95% CI: 2.22-2.83) with a risk difference of 1.25 per 1,000 person-years. The IR, 10.64 per 1,000 person-years, and risk difference, 5.42 per 1,000 person-years, was the highest for those with elderly onset (≥60 years) IBD. There was a stronger association for those with extensive ulcerative colitis (E3), primary sclerosing cholangitis, extraintestinal manifestations and perianal disease. HRs for VTE were persistently elevated across follow-up time, but was higher during the first year of follow-up (Figure 1).Conclusion: The risk of VTE was doubled in these modern-day data and remained elevated across follow-up time. Disease characteristics associated with higher inflammatory burden at diagnosis and older age are markers of increased risk. This underscores the importance of continuous vigilance and individual assessment of risk factors for VTE in patients with IBD.

Tidskriftsartikel (refereegranskat)abstract
- Background: The EpiCom-study investigates a possible East-West-gradient in Europe in the incidence of IBD and the association with environmental factors. A secured web-based database is used to facilitate and centralize data registration. Aim: To construct and validate a web-based inception cohort database available in both English and Russian language. Method: The EpiCom database has been constructed in collaboration with all 34 participating centers. The database was translated into Russian using forward translation, patient questionnaires were translated by simplified forward-backward translation. Data insertion implies fulfillment of international diagnostic criteria, disease activity, medical therapy, quality of life, work productivity and activity impairment, outcome of pregnancy, surgery, cancer and death. Data is secured by the WinLog3 System, developed in cooperation with the Danish Data Protection Agency. Validation of the database has been performed in two consecutive rounds, each followed by corrections in accordance with comments. Results: The EpiCom database fulfills the requirements of the participating countries local data security agencies by being stored at a single location. The database was found overall to be "good" or "very good" by 81% of the participants after the second validation round and the general applicability of the database was evaluated as "good" or "very good" by 77%. In the inclusion period January 1st -December 31st 2010 1336 IBD patients have been included in the database. Conclusion: A user-friendly, tailor-made and secure web-based inception cohort database has been successfully constructed, facilitating remote data input. The incidence of IBD in 23 European countries can be found at www.epicom-ecco.eu. (C) 2011 European Crohns and Colitis Organisation. Published by Elsevier B.V. All rights reserved.
