Tidskriftsartikel (refereegranskat)abstract
- Background: Multiple studies have described the effectiveness of ustekinumab (UST) and vedolizumab (VDZ) in patients with Crohn's disease (CD) failing anti- Tumor necrosis factors (TNFs); however, the effectiveness of VDZ or UST as a third-class biologic has not yet been described.Aims and Methods: In this retrospective multicenter cohort study, we aimed to investigate the effectiveness of VDZ and UST as a third-class biologic in patients with CD.Results: Two-hundred and four patients were included; 156/204 (76%) patients received VDZ as a second- and UST as a third-class therapy (group A); the remaining 48/204 (24%) patients received UST as a second- and VDZ as a third-class therapy (group B). At week 16-22, 87/156 (55.5%) patients and 27/48 (56.2%) in groups A and B, respectively, responded to treatment (p = 0.9); 41/156 (26.2%) and 15/48 (31.2%) were in clinical remission (p = 0.5). At week 52; 89/103 (86%) patients and 25/29 (86.2%) of the patients with available data had responded to third-class treatment in groups A and B, respectively (p = 0.9); 31/103 (30%) and 47/29 (24.1%) were in clinical remission (p = 0.5).Conclusion: Third-class biological therapy was effective in more than half of the patients with CD. No differences in effectiveness were detected between the use of VDZ and UST as a third-class agent.

- (1) Background: Villous atrophy is an indication for small bowel capsule endoscopy (SBCE). However, SBCE findings are not described uniformly and atrophic features are sometimes not recognized; (2) Methods: The Delphi technique was employed to reach agreement among a panel of SBCE experts. The nomenclature and definitions of SBCE lesions suggesting the presence of atrophy were decided in a core group of 10 experts. Four images of each lesion were chosen from a large SBCE database and agreement on the correspondence between the picture and the definition was evaluated using the Delphi method in a broadened group of 36 experts. All images corresponded to histologically proven mucosal atrophy; (3) Results: Four types of atrophic lesions were identified: mosaicism, scalloping, folds reduction, and granular mucosa. The core group succeeded in reaching agreement on the nomenclature and the descriptions of these items. Consensus in matching the agreed definitions for the proposed set of images was met for mosaicism (88.9% in the first round), scalloping (97.2% in the first round), and folds reduction (94.4% in the first round), but granular mucosa failed to achieve consensus (75.0% in the third round); (4) Conclusions: Consensus among SBCE experts on atrophic lesions was met for the first time. Mosaicism, scalloping, and folds reduction are the most reliable signs, while the description of granular mucosa remains uncertain.

- BACKGROUND: Accurate inflammation reporting in capsule endoscopy (CE) is important for diagnosis and monitoring of treatment of inflammatory bowel disease (IBD). Fecal calprotectin (FC) is a highly specific biomarker of gut inflammation. Lewis score (LS) was developed to standardize quantification of inflammation in small-bowel (SB) CE images.GOALS: Multicenter retrospective study aiming to investigate correlation between LS and FC in a large group of patients undergoing CE for suspected or known small-bowel IBD, and to develop a model for prediction of CE results (LS) based on FC levels.STUDY: Five academic centers and a district general hospital offering CE in UK, Finland, Sweden, Canada, and Israel. In total, 333 patients were recruited. They had small-bowel CE and FC done within 3 months.RESULTS: Overall, correlation between FC and LS was weak (r s: 0.232, P < 0.001). When two clinically significant FC thresholds (100 and 250 μg/g) were examined, the r s between FC and LS was 0.247 (weak) and 0.337 (moderate), respectively (P = 0.307). For clinically significant (LS ≥ 135) or negative (LS < 135) for SB inflammation, ROC curves gave an optimum cutoff point of FC 76 μg/g with sensitivity 0.59 and specificity 0.41.LIMITATIONS: Retrospective design.CONCLUSIONS: LS appears to show low correlation with FC as well as other serology markers of inflammation. FC does not appear to be a reliable biomarker for significant small-bowel inflammation. Nevertheless, FC level ≥ 76 μg/g may be associated with appreciable visual inflammation on small-bowel CE in patients with negative prior diagnostic workup.

- BACKGROUND AND AIMS: Capsule endoscopy (CE) has revolutionized small-bowel (SB) investigation. Computational methods can enhance diagnostic yield (DY); however, incorporating machine learning algorithms (MLAs) into CE reading is difficult as large amounts of image annotations are required for training. Current databases lack graphic annotations of pathologies and cannot be used. A novel database, KID, aims to provide a reference for research and development of medical decision support systems (MDSS) for CE.METHODS: Open-source software was used for the KID database. Clinicians contribute anonymized, annotated CE images and videos. Graphic annotations are supported by an open-access annotation tool (Ratsnake). We detail an experiment based on the KID database, examining differences in SB lesion measurement between human readers and a MLA. The Jaccard Index (JI) was used to evaluate similarity between annotations by the MLA and human readers.RESULTS: The MLA performed best in measuring lymphangiectasias with a JI of 81 ± 6 %. The other lesion types were: angioectasias (JI 64 ± 11 %), aphthae (JI 64 ± 8 %), chylous cysts (JI 70 ± 14 %), polypoid lesions (JI 75 ± 21 %), and ulcers (JI 56 ± 9 %).CONCLUSION: MLA can perform as well as human readers in the measurement of SB angioectasias in white light (WL). Automated lesion measurement is therefore feasible. KID is currently the only open-source CE database developed specifically to aid development of MDSS. Our experiment demonstrates this potential.

- Background: In the medical literature, the nomenclature and descriptions (ND) of small bowel (SB) ulcerative and inflammatory (U-I) lesions in capsule endoscopy (CE) are scarce and inconsistent. Inter-observer variability in interpreting these findings remains a major limitation in the assessment of the severity of mucosal lesions, which can impact negatively on clinical care, training and research on SB-CE. Objective: Focusing on SB-CE in Crohn’s disease (CD), our aim is to establish a consensus on the ND of U-I lesions. Methods: An international panel of experienced SB-CE readers was formed during the 2016 United European Gastroenterology Week meeting. A core group of five CE and inflammatory bowel disease (IBD) experts established an Internet-based, three-round Delphi consensus but did not participate in the voting process. The core group built illustrated questionnaires, including SB-CE still frames of U-I lesions from patients with documented CD. Twenty-seven other experts were asked to rate and comment on the different proposals for the ND of the most frequent SB U-I lesions. For each round, we used a 6-point rating scale (varying from ‘strongly disagree’ to ‘strongly agree’). The consensus was reached when at least 80 % of the voting members scored the statement within the ‘agree’ or ‘strongly agree’ categories. Results: A 100% participation rate was obtained for all the rounds. Consensual ND were reached for the following seven U-I lesions: aphthoid erosion, deep ulceration, superficial ulceration, stenosis, edema, hyperemia and denudation. Conclusion: Considering the most frequent SB U-I lesions seen in CE in CD, a consensual ND was reached by the international group of experts. These descriptions and names are useful not only for daily practice and medical education, but also for medical research.

- BACKGROUND: Idiopathic Thrombocytopenic Purpura (ITP) is an acquired haematological disorder with an incidence of 1 to 6 per 100,000/year. ITP and inflammatory bowel disease (IBD) comorbidity has been reported in the literature, but insights regarding the course, outcome and optimal management are limited by its rarity. The current study aimed to evaluate the clinical presentation and outcome of ITP in patients with IBD.METHODS: This multicentre retrospective case series was performed as part of the ECCO Collaborative Network of Exceptionally Rare case reports (CONFER) project. Cases of patients with ITP and IBD were collected by participating investigators. Clinical data were recorded in a standardised collection form.RESULTS: This report includes 32 patients with concurrent ITP and IBD:10 were females, median age was 32.0 [interquartile range (IQR) 20.5-39.5]. 14 patients had a diagnosis of Crohn's disease (CD) and the other 18 had of ulcerative colitis (UC). The diagnosis of IBD preceded the ITP in 26 patients (median time between diagnoses was 7.0 years [IQR, 1.5-9.5]). Among those patients, 17 patients were in clinical remission at ITP diagnosis. 13 patients were treated with mesalamine, 4 with oral corticosteroids, 1 with rectal corticosteroids, 2 with azathioprine, and 5 with anti-TNF agents. The median platelet count was 35,000/mmc (IQR, 10,000-70,000). 8 patients had rectal bleeding, 13 had skin purpura, 3 had epistaxis, 6 had mucosal petechiae, and 13 were asymptomatic. Regarding ITP treatment, 19 were treated with corticosteroids, 1 with Anti-RhD immunoglobulin, 12 with intravenous immunoglobulins (IVIG), 4 with thrombopoietin, 3 with rituximab and 6 patients eventually required splenectomy. 10 patients needed no treatment directed to the ITP.Three patients required colectomy during term long follow-up, due to IBD or cancer and not to massive bleeding as a complication of ITP. One patient of eight patients who presented with rectal bleeding required splenectomy, and none required urgent colectomy. Two patients died during the follow-up, one of them due to bleeding complication located in the upper gastrointestinal tract.Median follow-up time was 6.5 years [IQR, 3-10]. With long-term follow-up, all patients had platelet count above 50,000/mmc, and 24 were in IBD clinical remission.CONCLUSION: Most ITP cases in this case series occurred after the IBD diagnosis and responded well to regular ITP treatment. The course of the ITP in the IBD patients follows an expected course, including response to medical therapy and low rates of splenectomy.

- Background and study aims: Video capsule endoscopy (VCE) is invaluable in the diagnosis of small-bowel pathology. Capsule retention is a major concern in patients with Crohn's disease. The patency capsule was designed to evaluate small-bowel patency before VCE. However, the actual benefit of the patency capsule test in Crohn's disease remains unclear. The aim of this study was to evaluate the clinical impact of patency capsule use on the risk of video capsule retention in patients with established Crohn's disease. Patients and methods: This was a retrospective, multicenter study of patients with established Crohn's disease who underwent VCE for clinical need. The utilization strategy for the patency capsule was classified as selective (only in patients with obstructive symptoms, history of intestinal obstruction or surgery, or per treating physician's request) or nonselective (all patients with Crohn's disease). The main outcome was video capsule retention in the entire cohort and within each utilization strategy. Results: A total of 406 patients who were referred for VCE were included in the study. VCE was performed in 132 /406 patients (32.5 %) without a prior patency capsule test. The patency capsule test was performed in 274 /406 patients (67.5 %) and was negative in 193 patients. Overall, VCE was performed in 343 patients and was retained in the small bowel in 8 (2.3 %). In this cohort, the risk of video capsule retention in the small bowel was 1.5 % without use of a prior patency capsule and 2.1 % after a negative patency test (P = 0.9). A total of 18 patients underwent VCE after a positive patency capsule test, with a retention rate of 11.1 % (P = 0.01). Patency capsule administration strategy (selective vs. nonselective) was not associated with the risk of video capsule retention. Conclusions: Capsule retention is a rare event in patients with established Crohn's disease undergoing VCE. The risk of video capsule retention was not reduced by the nonselective use of the patency capsule. Furthermore, VCE after a positive patency capsule test in patients with Crohn's disease was associated with a high risk of video capsule retention.
