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]

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: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]

Background and Aims: More than half of patients with Crohn's disease [CD] develop disease complications requiring aggressive medical therapy or surgery over time. However, predicting disease course and treatment response remains difficult. We therefore identified distinctive serum analytes associated with disease activity and course in newly diagnosed, untreated patients at presentation and during their follow-up. Methods: In a pilot study, a multiplex immunoassay analysis on 36 markers was performed on serum from 20 CD patients at the time of primary diagnosis following endoscopic evaluation. The 12 most potent markers associated with disease activity, phenotype and course were analysed in a consecutive cohort of 66 CD patients at diagnosis and follow-up [n = 39]. A healthy control group [n = 20] was included as a reference. Results: CD patients had higher baseline levels of sTNF-R2 [p = 0.001], sIL-2R [p = 0.0001], and MMP-1 [p = 0.001] compared with healthy controls. Serial measurements revealed that these three analytes dropped statistically significantly from baseline level during remission and were high during exacerbation. Great decline of sTNF-R1 levels was found during remission, with 6.7-fold lower levels than in healthy controls [p = 0.015]. Patients who did not respond to initial prednisone treatment had higher baseline levels of sTNF-R2 [p = 0.001]. Patients experiencing relapses during follow-up had lower baseline sTNF-R2 and VCAM levels compared with patients with long-lasting remission. Conclusions: In a large cohort of newly diagnosed untreated CD patients, we identified candidate serum markers [sTNF-R1, sTNF-R2, sIL-2R, and MMP-1] associated with disease activity. Furthermore, sTNF-R2 was associated with prednisone response and, together with VCAM, with long-lasting remission. [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]
