Summary

AI Generated

Blinded assessment of confocal laser endomicroscopy recordings in IBS patients shows 81% agreement between two experienced assessors in identifying acute food-induced mucosal alterations in the duodenum.

Two blinded assessors with at least 20 exams experience each agreed on presence or absence of mucosal alterations in 81% of 75 video sequences from 13 non-constipated Rome IV IBS patients, yielding a Cohen's Kappa of 0.63 indicating substantial agreement.
Confocal laser endomicroscopy was performed during upper endoscopy to visualize duodenal mucosa before and after sequential application of six dissolved lyophilized food antigens (fish, nuts, egg white, soy, milk, wheat) in patients without allergic sensitization.
Among sequences with agreement, 52% showed fluorescence leakage and cell shedding on at least three mucosal spots, while 48% were judged normal.
The authors suggest that modifying assessment criteria might further increase agreement rates and validity of the technique for evaluating food-triggered epithelial barrier disruption in IBS.

Abstract

Introduction

Irritable bowel syndrome (IBS) is a common disorder of gut brain interaction (DGBI) characterized by abdominal pain associated with altered bowel habits – symptoms are often related to food intake. Confocal laser endomicroscopy (CLE) has shown acute food-triggered disruption of the epithelial barrier in the duodenum of IBS patients. While this technique promises new insights into the pathophysiology of IBS, image interpretation is subjective and interobserver agreement rates have not been assessed.

Aims & Methods

Aim: To assess the agreement rate between assessors regarding acute food induced mucosal changes visualized by CLE.
Methods: In Rome IV IBS (non-constipated) patients, allergic sensitization to nutrients was excluded by specific serum Immunoglobulin E tests. CLE was performed during upper GI endoscopy: duodenal mucosa was visualized before and after sequential application of 10mL dissolved aliquots of lyophilized fish, nuts, egg white, soy, milk and wheat. Two investigators (experience of ≥20 exams each) assessed separately recorded sequences for the presence or absence of acute mucosal alterations defined as fluorescence leakage and cell shedding visualized on ≥3 different mucosal spots. Assessors were blinded for patient characteristics, and for the timepoint of recordings (i.e. baseline or after food administration). Agreement rates are reported in percent and using Cohen’s Kappa computed with Rstudio.

Results

A total of 75 video sequences from 22 procedures in 13 patients were interpreted. Regarding presence or absence of mucosal alterations, assessors agreed in 81% (61/75) of assessed sequences resulting in a Cohen’s Kappa of 0.63.
Overall, 52% (32/61) of sequences with agreement were judged by both assessors to present leakiness and cell shedding whereas 48% (29/61) were considered normal.

Conclusion

When assessed in a blinded manner, mucosal leakiness is visualized on CLE recordings with a high agreement rate between assessors and substantial agreement when accounting for random chance agreement. Further increasing agreement rates by possibly modifying criteria might increase the validity of this technique.

Abstract

Introduction

Inflammatory bowel disease (IBD) is a chronic relapsing–remitting condition that impairs health-related quality of life (HRQoL), even in remission. Beyond physical symptoms, IBD is associated with anxiety, depression, and persistent fatigue, affecting up to 70% of patients during flares and 40% in remission¹. Despite its impact, specific therapies for chronic fatigue in IBD are lacking. Physical exercise has shown benefits in other immune-mediated diseases^2,3, but data in IBD are limited. A previous pilot study from our group showed that a 12-week supervised exercise programme improved fatigue, HRQoL, and fitness.⁴ To further investigate these findings in a larger cohort, this RCT was conducted.

Aims & Methods

In a multicentre, randomised trial, adults (18–67 years) with quiescent IBD and chronic fatigue (≥3 months; IBD-F section I ≥11) were randomised 1:1 to the intervention or control group. The intervention comprised a 12-week supervised intensive exercise programme with three personalised one-hour sessions per week, each consisting of 30 min of aerobic training and 30 min of resistance training and included cardiopulmonary exercise testing within the intervention group pre- and post-intervention. Controls received standard care and written advice about daily exercise. Primary outcomes were fatigue (IBD-F) and HRQoL (IBDQ) at 12 weeks. Secondary outcomes included anxiety and depression (PROMIS), sleep quality (PSQI), cardiorespiratory fitness, body composition, disease activity, adverse events and long-term effects on fatigue and HRQoL (6 and 12 months).

Results

In total, 100 patients were randomised. Of them, 95 participants completed the study and were included in the analysis (mean age 43.2 ± 11.5 years; 74% female; 62% CD, 36% UC, 2% IBD-U). Fatigue decreased more in the intervention group as compared to the control group (adjusted mean 36.5 ± 2.6 vs 45.3 ± 2.6; p = 0.014, respectively) and HRQoL increased more in the intervention group as compared to the control group (adjusted mean 175.6 ± 2.9 vs 166.6 ± 2.9; p = 0.024, respectively); both remained significant after Bonferroni correction. Longitudinal mixed-model analyses up to 12 months showed significant time-by-group interactions for IBD-F section 1 (p = 0.023) and IBDQ total (p = 0.037), while the interaction for IBD-F total was not statistically significant (p = 0.072). Anxiety (PROMIS-A) decreased (p = 0.030). Cardiorespiratory fitness improved in the intervention group compared with pre-intervention measurements (VO₂max p < 0.001, maximum power p < 0.001, heart rate recovery after 2 min p = 0.014) and body fat decreased (p = 0.024). Depressive symptoms (PROMIS-D) and sleep quality showed no significant group differences.

Conclusion

This 12-week personalised, supervised exercise programme improved fatigue and HRQoL in patients with quiescent IBD and chronic fatigue, and was additionally associated with improvements in anxiety and physical fitness. Benefits appeared to persist during follow-up, although the magnitude of effect attenuated over time. These findings support intensive exercise as a promising strategy for managing IBD-related fatigue.

Abstract

Introduction

Gender-specific differences in adult patients with immune mediated diseases like inflammatory bowel diseases (IBD) or coeliac diseases are increasingly recognised (1). In paediatric patients, gender differences in the incidence of IBD have been identified in a pooled analysis of population-based studies (2). However, gastrointestinal (GI) symptoms associated with paediatric IBD or coeliac disease and possible gender differences in GI symptoms have not been systematically studied.

Aims & Methods

Our aim was to utilise the newly developed, validated paediatric Structured Assessment of Gastrointestinal Symptoms (pSAGIS) scale to systematically assess GI symptoms in children with Crohn’s disease, ulcerative colitis, and coeliac disease by gender in an paediatric gastrointestinal outpatient clinic.
The pSAGIS is a patient-reported outcome measure (PROM) that consists of 21 GI-related questions and assesses the type and five severity grades of symptoms.
pSAGIS scales were completed by patients or their caregivers attending the GI outpatient unit of St. Anna Children’s Hospital, Vienna, Austria between the years 2016 and 2020. The diagnoses of patients were established on clinical terms after a complete examination deemed clinically necessary. Based on pSAGIS, an overall GI-symptom score was calculated as the sum of each individual symptom score for patients with Crohn’s disease, ulcerative colitis and coeliac disease, and symptom scores were compared between female and male patients. In addition, GI symptoms were summarised in five symptom groups (abdominal pain, dyspepsia, diarrhea, constipation, dysphagia/nausea). Data are given as mean ± standard deviation (SD), a p-value <0.05 was considered significant.

Results

From 3344 collected pSAGIS questionnaires 12.9% (n=430) were completed by children diagnosed with Crohn’s disease (71.9% male, 28.1% female), 9.0% (n=302) with ulcerative colitis (57.0% male, 43.0% female), and 24.7% (n=827) with coeliac disease (36.4% male, 63.6% female). In patients with Crohn’s disease the overall GI-symptom score was significantly higher among female patients comparing to male patients (7.3±10,1 vs. 2. 8±4,2, p<0.001) while in patients with ulcerative colitis overall symptom scores were higher in male than in female patients (5.6±8.5 vs 2.9±5.9; p=0.002). The table shows scores of symptom groups in patients with Crohn's disease and ulcerative colitis. The overall GI symptom score was low in patients with coeliac disease, and no significant differences were found between male and female coeliac patients (3.1±4.6 vs. 3.9±6.4, p=0,064).

	Crohn's disease			Ulcerative colitis
	male	female	p-value	male	female	p-value
abdominal pain	1.0±2.1	2.6±3.8	<0.0001	1.7±2.7	1.3±2.9	0.1692
dyspepsia	0.9±1.5	2.7±4.7	<0.0001	1.5±2.6	0.4±1.2	<0.0001
diarrhea	0.5±1.1	0.8±1.7	0.0247	1.8±3.0	0.6±1.7	<0.0001
constipation	0.2±0.6	0.4±1.0	0.0042	0.2±0.6	0.4±0.8	0.0771
dysphagia/nausea	0.3±0.8	0.8±1.4	<0.0001	0.4±1.2	0.2±0.9	0.3156
	Mean symptom score ± SD			Mean symptom score ± SD

Conclusion

Gender specific symptoms and symptom burden exist in paediatric patients with Crohn’s disease and ulcerative colitis. These gender differences may affect time to diagnosis, initiation of treatment and adherence to treatment and need further investigation. The pSAGIS is an easy adjunct to gastrointestinal history taking and allows a valid and systematic symptom assessment in a paediatric outpatient clinic.
