Introduction

IBD is a global health problem. It is necessary to understand the evolution and treatment exposure in a cohort of newly diagnosed IBD patients in the biologic era in the South of Europe

Aims & Methods

Aims: 1) To describe the main epidemiological and clinical characteristics of patients at IBD diagnosis and the long-term outcomes; 2) to analyse the use of drugs for IBD, and the need of hospitalisations and surgeries; 3) to compare IBD management based on the type of disease and the resources of the hospitals.
Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD —Crohn’s disease (CD), ulcerative colitis (UC) or IBD unclassified— during 2017 in the 17 Spanish regions were included. Patients who consented were followed-up for 5 years (yr) after diagnosis. Treatment was grouped into 5 categories: mesalamine (oral or topical), steroids (intravenous, oral, or topical), immunomodulators (thiopurines, methotrexate or cyclosporine), biologics (anti-TNF, vedolizumab, ustekinumab) or JAK inhibitors (JAKi), and surgery. Hospitals were classified into high resources and low resources ones. Cumulative incidence of exposure to each of the studied treatments was estimated by Kaplan-Meier curves; curves were compared with log-rank test.

Results

A total of 3,301 incident cases of IBD diagnosed during 2017 in 108 hospitals, covering over 22 million inhabitants in Spain (about 50% of the population), were enrolled into the follow-up study. Main characteristics of the cohort are summarised in table 1A and 1B. Median diagnosis delayed was 3.5 months (5.6 in CD and 2.7 in UC, p<0.001). During the 5-yr follow-up, 25% of UC patients progressed to more extensive involvement, while 8% of CD patients with inflammatory behaviour progressed to either stricturing or fistulising behaviour. Most of the patients who received mesalamine, corticosteroids, or immunomodulators initiated treatment within the first 2 years after diagnosis (figure 1). However, the cumulative incidence of biologics/JAKi usage steadily increased over time, reaching 49% by the 5-yr timepoint in CD. In terms of surgeries, a progressive increase in cumulative incidence was observed in CD; however, the incidence of colectomy remained stable in UC from the 2^nd year post-diagnosis. The management and progression of IBD unclassified were similar to that of UC. Regarding the type of hospital, a higher cumulative incidence of biologics/JAKi usage, hospitalisations, and surgeries was observed in CD at high resources hospitals. No differences were observed in the use of other therapeutic resources or the management of UC.

Conclusion

In the EpidemIBD large-scale epidemiological study, we have observed that the delay in diagnosing IBD is shorter than previously described. Approximately 50% of patients with CD and 20% of patients with UC end up receiving biologics/JAKi in the first 5 yrs following diagnosis. The percentage of patients undergoing surgery was lower than previously reported; in the case of UC, the majority of colectomies occurred within the first 2 yrs after diagnosis.

Introduction

Individuals with coeliac disease (CeD) commonly complain of persistent symptoms despite adhering to a gluten free diet (GFD). We analysed baseline data from the prospective pseudonymized German CeD Registry to identify factors associated with ongoing complaints.

Aims & Methods

​​​​​​After written informed consent, participants self-reported demographic, clinical and healthcare related information at baseline and yearly thereafter. Symptoms before diagnosis and during the four weeks prior to completing the baseline questionnaire were retrospectively assessed. Factors associated with symptoms after at least one year of gluten-free diet (GFD) were evaluated by multivariate logistic regression.

Results

From 11/2019 to 10/2021, 2164 participants provided baseline data: 78% were female, median age 36 years (range 1.1 to 93.2), median time since diagnosis 6.3 years (0 to 58.7), and median diagnostic delay (time from first symptom to diagnosis) 2.2 years (0 to 64.8). Most common symptoms before diagnosis included abdominal pain (83%), bloating (82%), fatigue (78%), and diarrhoea (71%). Individuals diagnosed in adulthood were more symptomatic compared to paediatric patients. Although 93.4% of participants reported improvement after diagnosis, a substantial proportion of those keeping a GFD >1year (n=1861, 86% of cohort) had ongoing symptoms. Factors associated with regularly experiencing above symptoms included female gender, having the same symptom before diagnosis, feeling insufficiently informed by their physician about CeD and implications for their daily life, and age at diagnosis (per decade), but not time since diagnosis (table).

Conclusion

Our findings revealed deficits in awareness, the diagnostic process, and post-diagnostic care. In this large cohort of patients with CeD we identified factors associated with persistence of symptoms despite keeping a GFD for at least one years. Early diagnosis, providing comprehensive education after confirmed diagnosis, and ensuring strict dietary adherence are pivotal for symptom resolution. A population-based mass-screening for CeD in childhood should be further explored. Implementing a multifaceted approach will enhance care for individuals with CeD and ultimately improve long-term health and well-being.

Introduction

Patients with Hypermobile Ehlers Danlos Syndrome (hEDS) have a high prevalence of Disorders of Gut-Brain Interaction (DGBI) and pose complex nutritional challenges in gastroenterology clinic. Despite this, little is known regarding nutrient intake and adequacy in hEDS.

Aims & Methods

Our aim was to assess nutrient intake and adequacy of patients with hEDS, as well as to determine which factors, including co-existent DGBI, are associated with poor intake. We conducted a cross sectional survey of patients with hEDS from two tertiary neurogastroenterology clinics as well as the Ehlers-Danlos Support UK. Inclusion criteria were adults with hEDS, exclusion criteria were those currently or previously using artificial nutrition. Patients completed the validated semi-quantitative Scottish Collaboration Group Food Frequency Questionnaire (FFQ) alongside questionnaires characterising: demographics, DGBIs (Rome IV), gastrointestinal, mood, somatic and autonomic symptoms, past history of eating disorders and screen for Avoidant Restrictive Food Intake Disorder (ARFID) using the Nine Item Avoidant-Restrictive Scale (NIAS). Nutrient intake was calculated from the FFQ and nutrient adequacy was calculated by comparison with UK daily reference values (DRVs) for age and sex. Unpaired t-tests were performed to compare nutrient intakes among patients with and without comorbidities, including the most common DGBIs.

Results

425 participants were included in the final analysis (mean: 41 years, 96% female). Only 48.5% reported BMI in the normal range, whereas 5.2% were underweight (BMI <18.5 kg/m²)and46.4% were overweight/obese (BMI >25 kg/m²). Only one third met their estimated average requirements (EAR) for energy (kcal/d). The majority met their reference nutrient intake (RNI) for protein (87.3%) and fat (72.5%), in contrast to only 21.2% for carbohydrate. Fibre intakes were very low (AOAC mean 23.7g/day (SD: 12.7) with only 24.7% meeting the RNI of 30 g/d. More than 58% of participants met/exceeded their DRV for micronutrients (zinc, magnesium, copper, manganese and selenium) and >95% for vitamins. Patients with functional nausea (n=157) were less likely to meet their protein requirements compared to those without (82.2% vs. 90.3%, p=0.015) and also had lower intakes for sodium (p=0.02), magnesium (p=0.02), calcium (p=0.01), zinc (p=0.002), selenium (p=0.03), folic acid (p=0.02) and vitamin C (p=0.05). Patients with previous eating disorders were less likely to meet nutrient requirements for thiamine (p=0.01) and vitamin B12 (p=0.04). Patients with ARFID (n=110) were less likely to meet requirements for all nutrients (except fat, calcium, vitamin D, vitamin B12) compared to patients without.

Conclusion

Patients with hEDS are rarely underweight and tend to consume high protein, high fat diets that are low in fibre. Functional nausea is the single most important DGBI impacting nutrient intake, as well as previous eating disorders and disordered eating (ARFID). These factors should be considered by clinicians and dietitians when assessing nutrient intake in this complex patient group.

Introduction

Coeliac disease (CeD) is a chronic immune-mediated enteropathy driven by dietary gluten proteins. Previous studies have indicated an increased risk of cardiovascular disease (CVD) in individuals with CeD [1-3]. However, results are inconsistent and specific guidelines on the management of CVD risk and comorbidities for individuals with CeD do not exist. In this study, we aimed to compare the distribution of traditional CVD risk factors in CeD patients and non-CeD controls from a population-based cohort.

Aims & Methods

We performed a CeD screening of 54,541 serum samples by anti-transglutaminase 2 immunoglobulin A and G serology from in total 56,042 adult participants in the fourth wave of the Norwegian Trøndelag Health Study (HUNT4) [4]. All seropositive participants were invited to upper endoscopy with duodenal biopsies to confirm a CeD diagnosis. Seronegative participants with previously diagnosed CeD were identified by linkage to hospital records and the Norwegian Patient Registry. We calculated SCORE2 and SCORE2-OP as predictors for 10-year risk of first-onset CVD [5, 6]. The groups “no CeD”, previously diagnosed CeD (“known CeD”) and CeD diagnosed in HUNT4 (“new CeD”), as well as “CeD” (known + new cases) were examined in this study. To compare group characteristics, we used the Wilcoxon rank sum test. Associations between groups and SCORE2(-OP) were assessed using ordinal logistic regression analysis.

Results

468 (0.80%) individuals received a CeD diagnosis in HUNT4, while 309 (0.57%) seronegative individuals had known CeD. Individuals with newly diagnosed CeD were younger, better educated, and had lower blood lipids compared to controls. Individuals with CeD smoked significantly less, had lower BMI and waist-hip-ratio, glycated hemoglobin levels, serum creatinine, and hsCRP levels compared to controls without CeD (n=52,438; p<0.05 for all variables mentioned, see table). We found a significantly lower SCORE2 for CeD cases (n=589) compared to controls (n=39,747; p<0.05). Adjustment for alcohol consumption did not affect group characteristics. A significantly lower SCORE2 was observed in CeD cases also after adjustment for level of education (OR .84, 95% CI .72-.98), high sensitivity C-reactive protein (hsCRP) and serum creatinine (OR .85, 95% CI .78-.99), but not for the combination of all three variables (OR .90, 95% CI .76-1.05).

Conclusion

Individuals with CeD appear to have a lower cardiovascular risk based on traditional risk factors like smoking habits, body fat, diabetes, renal function and inflammation compared to control individuals without CeD. In line with that, SCORE2 and SCORE2-OP as predictors for 10-year risk of first-onset CVD were lower in individuals with CeD.
