Time to evaluate diet quality and give dietary advice is limited in clinical inflammatory bowel disease (IBD) practice. The Eetscore is a web-based tool that assesses diet quality according to the Dutch dietary guidelines and provides personalised dietary advice. We aimed to assess diet quality of IBD patients using the Eetscore and to study changes in diet quality, health-related quality of life (HRQoL) and clinical disease activity over time. A prospective cohort study was performed in 195 adult IBD patients. Participants were invited to fill out questionnaires (Eetscore -FFQ, short Inflammatory Bowel Disease Questionnaire and Patient Harvey Bradshaw Index/Patient Simple Clinical Colitis Activity Index) at baseline and after 1 and 4 months. The Eetscore calculates diet quality based on sixteen food components (ten points per component, total score 0–160; the higher the better) and provides dietary advice per component based on the assessment. At baseline, mean diet quality was 98 (sd 19). Diet quality was positively associated with age, female sex and level of education. Component scores were highest for red meat, wholegrain products and sweetened beverages, and lowest for legumes, nuts and processed meat. Over time, diet quality increased to 107 (sd 21) at 4 months (P < 0·001). Each ten-point improvement in diet quality was associated with an increase in HRQoL (β = 0·4 (95 % CI (0·02, 0·7), P = 0·04). Clinical disease activity did not change. In conclusion, diet quality of IBD patients significantly improved following personalised dietary advice of the Eetscore. Improvement of diet quality was associated with a slight improvement in HRQoL. The Eetscore is a practical and useful tool to monitor and support a healthy diet in IBD patients.

Background and Aims Newly diagnosed inflammatory bowel disease [IBD] patients need to deal with the physical and emotional impact of the disease. We aimed to evaluate care for recently diagnosed IBD patients from the patient perspective and assess themes for improvement. Methods A mixed-method study with adult IBD patients 4–15 months after diagnosis was performed. First, relevant themes were identified through semi-structured interviews until data saturation. Next, a questionnaire assessing satisfaction with care [SATI-Q] was developed and validated with 15 items divided into two domains: medical care and information and psychosocial care. Higher scores indicate higher patient satisfaction [0–100]. Results We interviewed 20 patients. Next, 84/107 patients completed the SATI-Q: 51% female, aged 37 years (interquartile range [IQR 25–58]), 36% Crohn's disease, disease duration 9 months [IQR 6–12] and 74% in clinical remission. The median SATI-Q score was 82 [IQR 72–92]. Patients were more satisfied with medical care than with information and psychosocial care (score 92 [IQR 81–98] vs 74 [IQR 60–90], p < 0.001). Patients were least satisfied with the attention given to IBD-related emotions and information on IBD medication, diet and future perspectives [77, 76, 57 and 54% of patients satisfied]. Patients [81%] preferred spoken information. Only 26–27% preferred brochures and websites. Conclusions In this study, the SATI-Q questionnaire was developed and validated to assess patient satisfaction with care in early IBD. Our findings suggest that psychosocial care and information on IBD medication, diet influence and future perspectives for recently diagnosed IBD patients require improvement. [ABSTRACT FROM AUTHOR]

Monitoring of IBD patients on intravenous biologic treatment is recommended but time-consuming for patients and nurses. We developed a mobile application (app) to promote self-management and studied its feasibility in clinical practice. Adult IBD patients treated with intravenous infliximab or vedolizumab used the app over four biologic treatments. The app includes information modules and an interactive timeline with notifications of blood tests and health checks before treatment. In total, 55 patients participated of whom 71% had Crohn's disease and 85% used infliximab. Compliance with health checks and blood tests was 67% before the first biologic treatment and 70, 87, and 80% before the second, third, and fourth treatment, respectively. The median number of times the app was used per treatment varied from 6 to 8 times (≥4 considered sufficient). Patients were satisfied with the app [median VAS score 8 (IQR 7–9)] and remained equally satisfied with IBD care [score 8 (IQR 8–9) before and after app use]. Nurses contacted all patients by telephone before the first biologic treatment, as previous standard care. Before the second, third, and fourth treatment only 47, 35, and 49% of patients were contacted. The majority (92%) wanted to continue using the app after the study. Monitoring of IBD patients treated with intravenous biologics using an app is feasible. We saw high compliance, sufficient app use, and high patient satisfaction. Moreover, health-care utilization was reduced and almost all patients preferred using the app over previous standard care (ClinicalTrials.gov NCT04254614). [ABSTRACT FROM AUTHOR]

Background and Aims Segmentation of patients based on psychological determinants of subjective health may provide new ways to personalized care. The cross-disease segmentation model developed by Bloem & Stalpers discriminates patients based on disease acceptance and perceived control. We aimed to validate the segmentation model, compare segments and evaluate whether segments independently correlate with quality of life in inflammatory bowel disease [IBD]. Methods A cross-sectional study of adult IBD patients was performed with questionnaires on quality of life [32-item inflammatory bowel disease questionnaire], acceptance and perceived control [six items with 7-point Likert scale]. Four segments were formed [cut-off > 5]: [I] high acceptance, high control; [II] high acceptance, low control [III]; low acceptance, high control and; [IV] low acceptance, low control. Results We included 686 patients. The acceptance and perceived control scales were unidimensionally structured and internally consistent. Segments differed significantly in age, smoking behaviour, diagnosis, disease duration, extra-intestinal manifestations, IBD medication, clinical disease activity and quality of life. High acceptance (standardized beta coefficient [ß] 0.25, p < 0.001), high perceived control [ß 0.12, p < 0.001] or both [ß 0.53, p < 0.001], were associated with a significantly better health-related quality of life compared with low acceptance and low perceived control. Sociodemographic and clinical factors explained 25% of the variance in quality of life. The explained variance significantly increased to 45% when the patients' segment was added to the model [Δ R 2 20%, p < 0.001]. Conclusions The segmentation model based on disease acceptance and perceived control is valid in IBD patients and discriminates different segments that correlate independently with quality of life. This may open new strategies for patient care. [ABSTRACT FROM AUTHOR]

Immunotherapy, targeting programmed death-1 (PD-1) enhances antitumor T-cell activity in patients with malignancies. Blocking PD-1 or its ligand may lead to fulminant colitis as serious adverse event in these patients. Since little is known of the presence and role of PD-1+T cells in colitis of different etiologies, we determined PD-1+T cells in mucosal specimens of patients with inflammatory bowel disease, infectious colitis (InfC), immunotherapy-related colitis (ImC) and healthy controls (HC). Newly diagnosed patients with ulcerative colitis (UC, n = 73), Crohn's disease (CD, n = 50), InfC (n = 5), ImC (n = 8) and HC (n = 8) were included. Baseline inflamed colonic biopsies were studied with immunohistochemistry and flowcytometry. Using immunohistochemistry, PD-1 was not present on lymphocytes in the epithelium of all patients, nor in HC. The percentage PD-1+ of all lymphocytes in the lamina propria was 40% in UC, 5% in InfC, 3% in ImC and 0% in HC. Flowcytometry showed significant higher percentages of PD-1+T cells in inflamed biopsy specimens of UC patients (22%) compared to all other groups: CD patients (13%), InfC (12%), ImC (5%) and HC (6%). There are relevant differences in distribution and frequencies of mucosal PD-1+ T-cell subsets in patients with UC, CD, InfC and ImC, supporting the hypothesis that these types of colitis are driven by different immunological pathways. The increased numbers of PD-1+ and PD-L1+ lymphocytes in the colonic mucosa of UC patients suggest that the PD-1/PD-L1 pathway might be more activated in UC than in CD. [ABSTRACT FROM AUTHOR]

Background: The Dutch guidelines for esophageal and gastro-esophageal junction (GEJ) cancer recommend discussion of patients by a multidisciplinary tumor board (MDT). Despite this recommendation, one previous study in the Netherlands suggested that therapeutic guidance was missing for palliative care of patients with esophageal cancer. The aim of the current study was therefore to assess the impact of an MDT discussion on initial palliative treatment and outcome of patients with esophageal or GEJ cancer. Material and methods: The population-based Netherlands Cancer Registry was used to identify patients treated for esophageal or GEJ cancer with palliative intent between 2010 and 2017 in 7 hospitals. We compared patients discussed by the MDT with patients not discussed by the MDT in a multivariate analysis. Primary outcome was type of initial palliative treatment. Secondary outcome was overall survival. Results: A total of 389/948 (41%) patients with esophageal or GEJ cancer were discussed by the MDT before initial palliative treatment. MDT discussion compared to non-MDT discussion was associated with more patients treated with palliative intent external beam radiotherapy (38% vs. 21%, OR 2.7 [95% CI 1.8–3.9]) and systemic therapy (30% vs. 23%, OR 1.6 [95% CI 1.0–2.5]), and fewer patients treated with stent placement (4% vs. 12%, OR 0.3 [95% CI 0.1–0.6]) and best supportive care alone (12% vs. 33%, OR 0.2 [95% CI 0.1–0.3]). MDT discussion was also associated with improved survival (169 days vs. 107 days, HR 1.3 [95% CI 1.1–1.6]). Conclusion: Our study shows that MDT discussion of patients with esophageal or GEJ cancer resulted in more patients treated with initial palliative radiotherapy and chemotherapy compared with patients not discussed by the MDT. Moreover, MDT discussion may have a positive effect on survival, highlighting the importance of MDT meetings at all stages of treatment. [ABSTRACT FROM AUTHOR]

Introduction: A dysregulated intestinal T cell response is presumed in patients with inflammatory bowel disease [IBD]. In this longitudinal study, we investigated the changes in intestinal T lymphocyte subsets in IBD at first presentation and over time during endoscopic active or inactive disease, and relate them to disease activity and outcome. Methods: We included 129 newly diagnosed patients (87 Crohn's disease [CD], 42 ulcerative colitis [UC]) and 19 healthy controls [HC]. Follow-up biopsy specimens were analysed from 70 IBD patients. Immunophenotyping of specimens was performed by flow cytometry identifying lymphocyte subpopulations. Results: IBD patients at diagnosis displayed higher percentages of CD4 T+ cells, Tregs, and central memory T cells [TCM] and with lower percentages of CD8 and CD103 T lymphocytes than HC. Follow-up specimens of patients with endoscopic inactive disease showed T cell subset recovery comparable to HC. Endoscopic active disease at follow-up coincided with T cell subsets similar to those at diagnosis. In UC, lower baseline percentages of CD3 cells was associated with milder disease course without the need of an immunomodulator, whereas in CD, higher baseline percentages of CD4 and Tregs were associated with complicated disease course. Conclusions: The intestinal T cell infiltrate in IBD patients with active endoscopic disease is composed of increased percentages of CD4+ T cells, Tregs, and TCM, with lower percentages of CD8+ T cells and CD103+ T cells, compared with HC and endoscopic inactive IBD. Baseline percentages of CD3, CD4, and Tregs were associated with disease outcome. Further research is needed to demonstrate the predictive value of these lymphocyte subsets. [ABSTRACT FROM AUTHOR]

Background:Data on serum antibodies in untreated adult inflammatory bowel disease (IBD) patients at diagnosis are scarcely available, and results on the stability of antibody presence over time are inconsistent. Our aim was to investigate antibodies in newly diagnosed, untreated IBD patients in relation to disease phenotype and course. Furthermore, we analyzed antibody presence over time. Methods:Baseline anti-Saccharomyces cerevisiaeantibodies (ASCA), anti-chitobioside carbohydrate antibodies (ACCA), anti-laminaribioside carbohydrate antibodies (ALCA) and anti-mannobioside carbohydrate antibodies (AMCA) were measured with enzyme-linked immunosorbent assays and perinuclear anti-neutrophilic cytoplasmic antibodies (pANCA) was measured by indirect immunofluorescence in serum of 120 untreated IBD patients at diagnosis and 19 healthy controls. Antibodies were related to disease outcomes. Serial measurements were available in 71 patients. Results:The combination of pANCA and ASCA enabled good discrimination between UC and CD (p = .004). Antibody presence was relatively stable over time, even though there were significant changes in concentrations. There was a trend towards larger fluctuations in concentration with immunosuppressive medication. Baseline pANCA in UC patients correlated with calprotectin values (rho = .545,p = .019) and change in pANCA status over time was associated with disease activity at that moment. No associations were found with antibodies at diagnosis and disease outcomes. Conclusion:Antibody profiles at diagnosis support the distinction between CD and UC. Anti-glycan antibodies are reasonably stable over time, but may fluctuate under the influence of immunosuppressive treatment which may explain the inconsistency in findings hitherto. The appearance or disappearance of pANCA antibodies during follow-up correlated with disease activity in UC and may be used in disease monitoring. [ABSTRACT FROM PUBLISHER]

Placement of the duodenal-jejunal bypass liner (DJBL) is a minimally invasive technique for the management of patients with type 2 diabetes mellitus and obesity. Acute pancreatitis was seen in 5 of 167 patients (3 %) in our series. It is suggested that acute pancreatitis in patients with the DJBL results from either direct blockage or edema of the major duodenal papilla, which may be caused by the following: migration of the anchor of the DJBL, accumulation of food debris between the liner and the duodenal wall, or reflux of duodenal contents into the pancreatic duct due to intraluminal hypertension caused by the liner. Early removal of the DJBL resulted in fast and complete recovery, whereas delayed diagnosis and removal led to severe, necrotizing acute pancreatitis. [ABSTRACT FROM AUTHOR]

Background and study aims: Despite significant interest from health care authorities, patient organizations, and insurance companies, data on procedural outcome and quality of endoscopic retrograde cholangiopancreatography (ERCP) in general and academic practice are sparse. The aims of this study were to assess procedural outcome of ERCP within a large prospective registry in The Netherlands, and to evaluate associations between endoscopist-related factors and procedural outcome. Methods: All endoscopists performing ERCP in The Netherlands were invited to register their ERCPs over a 1-year period using the Rotterdam Assessment Form for ERCP (RAF-E). The primary outcome measure was procedural success. A priori difficulty level of the procedure was classified according to Schutz. Baseline characteristics of the endoscopist (e.g. previous experience) were recorded at study entry. Regression analysis was performed to identify predictors of procedural outcome. Results: A total of 8575 ERCPs were registered by 171 endoscopists from 61 centers, constituting about 50% of all ERCPs performed nationally during the study period. Overall procedural success was 85.8 %. Intact papillary anatomy was present in 5106 patients (59.5 %): procedural success in this subgroup of patients was 83.4% vs. 89.4% after sphincterotomy (P<0.001). Multivariate logistic regression identified "degree of difficulty," "intact papillary anatomy," and "previous ERCP failure" to be independently associated with procedural failure. "Yearly volume of ERCPs" and "trainee involvement" were independently associated with success. Conclusions: The nationwide prospective RAF-E registry proved to be a valuable tool to gain insight into procedural outcome of ERCPs. [ABSTRACT FROM AUTHOR]

Background & Aims: The patient segmentation model based on disease acceptance and perceived control may guide personalized care in inflammatory bowel disease (IBD). We aimed to investigate the external validity of the segmentation model and its consistency over time. Methods: This is a multicenter longitudinal cohort study of adult IBD patients with questionnaires on disease acceptance and perceived control (6-items, 7-point Likert scale) and health-related quality of life (HRQoL) (Short IBD questionnaire, range 10-70). Segments were created based on mean scores (cut-off>5): (I) high acceptance, high control; (II) high acceptance, low control; (III) low acceptance, high control and; (IV) low acceptance, low control. Results: The external validation cohort included 921 IBD patients. The acceptance and control scale were unidimensional and internally consistent. Segments differed significantly in gender, disease duration, IBD medication and clinical disease activity. High acceptance and/or high control were significantly associated with a higher HRQoL compared with low acceptance and low control (i.e., segment IV) (Beta (95%CI) segment I=11.7 (10.4-13.1), segment II=9.3 (7.7-10.9) and segment III=3.8 (1.6-6.0), p=0.001). The follow-up cohort included 783 patients: 58% remained in the same segment while 42% differed in segment over time. Changes in segment were positively correlated with changes in HRQoL over time (Spearman rho 0.38, p<0.001). Conclusions: The patient segmentation model based on disease acceptance and perceived control was externally valid and showed consistency over time. The different segments were independently associated with HRQoL. Future interventions should aim to personalize care based on segments and improve disease acceptance and perceived control of IBD patients. [ABSTRACT FROM AUTHOR]

Background: Self-expanding metal stents (SEMS) are known to have a significantly higher patency rate than plastic stents. We aimed to identify prognostic factors, besides stent type, for stent patency and to develop a score model that could further aid in guiding stent choice for the palliation of a malignant biliary stricture. Methods: A retrospective multicenter study was conducted. Data on consecutive patients who had a stent placed between January 2002 and July 2009 were collected. Cumulative stent occlusion rates were analyzed by Kaplan-Meier curves and log rank testing, and prognostic factors were assessed by Cox regression analysis. Results: A total of 690 stents (512 plastic stents, 174 SEMS) were endoscopically placed in 390 patients. At 8 weeks, stent occlusion had occurred in 32% of the plastic stents and 11% of the SEMS. Multivariate analysis indicated that plastic stents (hazard ratio [HR] 2.5, 95% confidence interval [CI] 1.9-3.5), a tight stricture requiring preceding dilation (HR 1.8, 95% CI 1.3-2.5), and a high initial bilirubin level (>50 μmol/L (HR 1.3, 95% CI 1.0-1.7) were independently associated with an increased risk of stent occlusion. A score model based on these 3 factors was able to distinguish between stent procedures with a relatively high and low risk of stent occlusion (median 14 vs. 26 weeks, respectively). Conclusion: Besides plastic stents, stricture severity requiring preceding dilation, and initial higher bilirubin level were associated with a shorter period of stent patency. A simple score model based on these factors was able to predict stent occlusion and may aid in choosing the most appropriate stent type in individual patients. [ABSTRACT FROM AUTHOR]

Objective. Gastrointestinal endoscopy databases are important for surveillance, epidemiology, quality control and research. A good quality of automatically generated databases to enable drawing justified conclusions based on the data is of key importance. The aim of this study is to validate the correctness of coding of a national automatically generated anonymous endoscopy database. Material and methods. We evaluated a total of 500 colonoscopies performed in five larger hospitals of the TRANS.IT project focusing on endoscopy reporting. Randomly 500 examinations were selected from a total of 5,000 examinations and their generated endoscopic terminology codes as well as complete reports were analysed. Indications for the examination and described findings were scored for correctness and clinical relevance of the coding that would be exported to the anonymous database. Results. Indications were correctly coded in 92% of all examinations (range 76–100%) per hospital. Correct coding of findings ranged from 42% to 93% per hospital (mean 77%). Different correct coding proportions were seen varying with the diagnosis, with the highest correct coding rates in polyps, carcinoma and diverticular disease. Incorrect coded examinations were scored for clinical relevance. Overall 11% of the investigated examinations were incorrectly coded with clinical relevance. Conclusions. Accuracy of clinically relevant endoscopy data recorded in the TRANS.IT anonymous central database is high. Further improvement is desirable, which may be achieved by education of individual endoscopists and enhancement of the program. [ABSTRACT FROM AUTHOR]

Background and Aims: Fatigue significantly impacts the quality of life of patients with inflammatory bowel disease (IBD). This study aimed to assess the effect of a personalized, intensive exercise program on fatigue, health-related quality of life (HRQoL), and cardiorespiratory fitness in patients with quiescent IBD and severe fatigue.Methods: A pilot study was performed including IBD patients in remission with severe fatigue. The 12-week exercise program consisted of three times per week 1-h sessions, including aerobic- and progressive-resistance training at personalized intensity based on a cardiopulmonary exercise test (CPET) and one-repetition maximum. CPET was repeated after 12 weeks. Fatigue and HRQoL were assessed using the checklist individual strength and 32-item IBD questionnaire.Results: Twenty-five IBD patients with mean age of 45 (± 2.6) years were included of which 22 (88%) completed the exercise program. Fatigue significantly improved from 105 (± 17) points on the checklist individual strength before, to 66 (± 20) after completion of exercise program (p < 0.001). Patients' HRQoL significantly improved from 156 (± 21) to 176 (± 19) (p < 0.001). When looking at the subdomains of HRQoL, significant improvement was seen in emotional (58 ± 12 vs. 69 ± 9.1, p = 0.003), systemic (19 ± 3.9 vs. 24 ± 4.7, p < 0.001), and social function (25 ± 5.4 vs. 30 ± 3.9, p < 0.001). Bowel symptoms did not change (53 ± 7.7 vs. 55 ± 7.3, p = 0.208). Repeat CPET showed a significant improvement in maximum power patients were able to deliver (2.4 ± 0.5 vs. 2.7 ± 0.5 W/kg, p = 0.002).Conclusions: A personalized, intensive exercise program can lead to significant improvement of fatigue, HRQoL, and cardiorespiratory fitness in patients with quiescent IBD and severe fatigue.

PNAd and MAdCAM-1 addressins on venules are of importance in T-cell homing and potential therapeutic targets in ulcerative colitis (UC). Normally, PNAd+ high endothelial venules (HEVs) are only present in lymphoid organs, whereas small numbers of MAdCAM-1+ venules can be seen in non-lymphoid tissue. We aimed to study their presence in the intestinal mucosa of UC patients at diagnosis and during follow-up, and their correlation with disease activity. Colonic biopsy specimens of 378 UC patients were analyzed by immunohistochemistry for CD3, CD20, ERG, MECA-79 (PNAd) and MECA-376 (MAdCAM-1) and compared to healthy controls (HC). The proportion of PNAd+HEVs in UC at diagnosis was 4.9% (IQR 2.0%–8.3%), while none were detected in HC. During follow-up, PNAd+HEVs completely disappeared in remission (n = 93), whereas the proportion in active disease was similar to baseline (n = 285, p = 0.39). The proportion of MAdCAM-1+venules in UC at baseline was 5.8% (IQR 2.6–10.0). During follow-up, the proportion in remission was comparable to diagnosis, but upregulated (7.5% (IQR 4.4–10.9), p = 0.001) in active disease. In conclusion, PNAd+HEVs appear in UC during active inflammation which could thus serve as a marker for disease activity, whereas MAdCAM-1+venules remain present after inflammation is resolved and increase after subsequent flares, reflecting chronicity and potentially serving as a therapeutic target.
