Introduction

Disease acceptance and perceived control have been proposed as general predictors of subjective health. Acceptance refers to the feeling that a disease and its resulting constraints are acceptable, whereas perceived control is the belief that one’s health condition can be influenced by oneself or by others. The current study sought to investigate to what extent disease acceptance and perceived control are associated with the valuable clinical endpoint of IBD-related disability.

Aims & Methods

In this cross-sectional study, adult IBD patients at a Belgian tertiary referral center received a survey with questions about clinical and demographic characteristics, the Subjective Health Experience (SHE) model questionnaire¹, and the shortened version of the IBD Disability Index (IBD Disk)². Analyses consisted of multiple linear regressions with IBD-related disability as dependent variable. The first model contained nine predictors: age, sex, IBD type, smoking, education, disease duration, current medication, number of IBD-medication types ever used, and previous bowel surgery. In the second model, disease acceptance and perceived control were added. This was tested in the total sample and in subgroups consisting only of patients with active disease and patients in remission, according to the two-component patient-reported outcome (PRO-2)^3,4.

Results

Out of 5091 patients who received the survey either digitally or on paper, 1458 patients responded (28.6% participation rate). Of those, 208 were excluded because of missing data. The remaining 1250 were included for the main analysis (54.2% female, median [IQR] age 51 [39-61] years, 61.3% Crohn’s disease). Across the total sample, model 2 explained significantly more variance in IBD-related disability compared to model 1 (R²_adj 37% vs. 19%, p<.001). Female sex, Crohn’s disease, current smoking, current steroids use, a higher number of medication types ever used and previous bowel surgery were positively correlated with disability, whereas a middle or high level of education and higher disease acceptance were negatively correlated with disability. Of all included factors, disease acceptance was most strongly associated with disability (β=-.43, p<.001). In subgroup analyses, the increase in explained variance from model 1 to model 2 was higher in the remission group (n=693) compared to the active disease group (n=378), respectively R²_adj 12% vs. 32%, p<.001 and R²_adj 13% vs. 22%, p<.001. Female sex, high level of education, number of medication types ever used and disease acceptance remained significantly associated with disability in both subgroups, and current smoking only in the active disease group. Acceptance remained the strongest variable associated with disability in both subgroups, β=-.46, p<.001 in the remission group and β=-.28, p<.001 in the active disease group. Perceived control was not a significant predictor in any of the analyses.

Conclusion

Disease acceptance is an important psychological factor that is more strongly associated with IBD-related disability than demographic and clinical characteristics. The association is stronger for IBD patients in remission compared to patients with active IBD. Perceived control had no added value on top of disease acceptance. These findings support future research into disease acceptance as a potential treatment target to improve IBD-related disability.

Introduction

Endoscopic submucosal dissection (ESD) is the first-line treatment for superficial gastric lesions with a negligible or very low risk of lymph node metastasis. However, a permanent risk of developing metachronous lesions persists. We intend to analyze the risk factors associated with the development of metachronous lesions in a population of patients undergoing ESD.

Aims & Methods

Prospective cohort study conducted at a single centre, involving patients who underwent gastric ESD for lesions between 2017 and 2023, with a follow-up period of ≥ 6 months. Lesion characteristics were analyzed, including the rate of metachronous lesions, and logistic regression was performed to identify risk factors associated with the development of metachronous lesions.

Results

Included 78 ESDs performed on gastric epithelial lesions (59% female), with a mean age of 70.3±7.9 years. Regarding family history of gastric adenocarcinoma, 17.9% of patients had a first-degree relative. Among the analyzed lesions: 42.3% measured between 0-20mm, 57.7% ≥ 20mm; 12.8% were sessile, 71.8% flat and 15.4% depressed; 19.2% were located in the cardia, fundus or body, 21.8% in the incisura angularis and 59% in the antrum. Regarding histological findings: 42.3% low-grade dysplasia, 30.8% high-grade dysplasia, 23.1% intramucosal adenocarcinoma and 3.8% adenocarcinoma with submucosal invasion. Nine metachronous lesions (11.5%) were detected, with a median time of occurrence of 24 [13-32] months. In the analysis of risk factors, statistical significance was found for location outside the antrum (21.6% vs. 1.9%; p=0.002) and the presence of adenocarcinoma (23.8% vs. 7%; p=0.039), but not for size ≥20mm (13.7% vs. 5.1%; p=0.178) or ulceration of the lesion (9.1% vs. 10.1%; p=0.915). Logistic regression analysis revealed that only location outside the antrum had a significant risk for the development of metachronous lesions (OR 13.4; 95% CI: 1.4-127.1).

Conclusion

Given the permanent risk of developing metachronous lesions, the identification of associated risk factors is important as it may eventually allow for the adaptation of surveillance programs.

Clinical Case Summary

The ubiquitous availability of digital media does not only have advantages. Inexperienced mushroom pickers increasingly frequently use APPs for mushroom identification and consume forest mushrooms with false security. Currently, for example, life-threatening Amanita phalloides poisoning is becoming more frequent.
A 65-year-old patient presented with a latency period of approximately 40 hours after consumption of the mushrooms. Nausea and vomiting, as well as loss of strength and cramps in arms and legs, had already been present for about 24 hours. Laboratory tests revealed coagulation failure and markedly elevated transaminases (INR 2.1, GOT 2590 U/l, GPT 3119 U/l). The Meld Score was 33. Only when asked explicitly the patient reported eating wild mushrooms he had collected. The vomit and mushroom debris were recovered and immediately examined by a mushroom expert. Immediately after admission to our intensive care unit, liver protective therapy with Silibinin and N-Acetylcysteine was initiated.
Analysis by a fungal expert revealed evidence of Amanita phalloides. At an INR of 3.3 with massive diffuse skin hemorrhages and rising transaminases (GOT 4825U/l, GPT 4104U/l), repeated therapeutic plasma exchange (exchange of 1.3 times the plasma volume) was performed to control the complications of liver failure. In the course, transaminases and coagulation parameters stabilized, and liver transplantation was not necessary. The patient is now in excellent general health.
Our patient case shows that early diagnosis, as well as therapy, are crucial to reducing the lethality of tuberous leaf fungus poisoning. Patients are often unaware of the danger, so if they have symptoms, they should be asked explicitly about consuming collected mushrooms. As a bridging therapy for the stabilization and regeneration of liver function, therapeutic plasma exchange is an excellent option.

Introduction

Autoimmune Atrophic Gastritis (AAG) is a chronic immune-mediated condition that mainly affects the body and fundus of the stomach. AAG is often under-diagnosed due to the slow progression of the disease and a variable spectrum of symptoms. Recent data suggests a potential role of altered gastric microbiota in the natural history of AAG, due to the potential overgrowth of bacteria linked to the development of neoplastic complications (neuroendocrine tumors- NETs and gastric cancer) (1,2). Moreover, the same data hypothesizes the use of fecal microbiota as a possible non-invasive marker to diagnose and monitor AAG. Thus, we aimed to prospectively characterize the salivary and fecal microbiota of patients with AAG to provide further insights in this field.

Aims & Methods

We collected salivary and fecal samples from consecutive patients with an established diagnosis of AAG, enrolled at the Gastroenterology Unit of Azienda Ospedale Università Padova from March to June 2023 at the time of endoscopic follow-up examination. All patients needed to be off Proton-Pump Inhibitors, antibiotics, and probiotics for at least one month before enrolment. Stool samples were collected by the patients on the day of the endoscopy, transferred in a buffer solution, and stored at -20°C. Oral samples were collected through salivary commercial kits and freezed at -20°C. Both salivary and faecal samples were analyzed by BMR Genomic (Padua, Italy) that amplified the V3-V4 hypervariable ribosomal RNA region. Sequencing of the 16S rRNA gene V3- V4 region was performed using the Illumina MiSeq. Preliminary analyses were conducted on individual fecal samples compared to an internal population of healthy subjects (provided by BMR genomics) using Qiime2 tools. Shannon–Wiener index was used to calculate α-diversity and then the microbial biodiversity index (MBI) and Dysbiosis Index (DI). Mann–Whitney tests were performed to verify statistical differences in the α-diversity across AAG patients and healthy subjects.

Results

We enrolled 15 AAG patients with a mean age of ± 63 ± 11 years (9/15 females). OLGA 2 stage was reported in 10/15 patients. Sixty percent of the patients showed a MBI between 7.11 and 12.45, indicating that each sample contained phylogenetically similar species. The remaining patients have an index greater than 12.45 compared to the healthy population. More than half of the patients had dysbiosis (>0.082). The highest indices of dysbiosis were found in patients with a history of NET (n=3), gastric cancer (n=1), and previous HP- infection and OLGA 3 stage (n=1). Firmicutes, Bacteroidetes, and Proteobacteria were more frequent phyla found in the fecal samples, whereas Enterobacteriaceae and Streptococcaceae were the most common bacterial families (13/15, 87%). In particular, Klebsiella and Campylobacter pathogens genera were found in some samples. Streptococcus and Prevotella were the most abundant genera found in the salivary samples.

Conclusion

Patients with AAG were found to have a great proportion of Firmicutes and Bacteroidetes, which aligns with the literature (3,4). Moreover, a dominant of Proteobacteria, especially Enterobacteriaceae commonly associated with proinflammatory states, was found. (5) Our preliminary data showed a possible positive association between higher degrees of dysbiosis and a previous history of NET or gastric cancer.

Introduction

Bowel urgency is increasingly recognized as a common and impactful symptom in patients with Ulcerative Colitis (UC)¹. However, there are limited data exploring the relationship of bowel urgency with work productivity. We examined the relative association of bowel urgency clinically meaningful improvement (CMI) and bowel urgency remission with Work Productivity and Activity Impairment (WPAI) scores in the presence of rectal bleeding (RB) remission and stool frequency (SF) remission as potential confounding variables using data from LUCENT-1 (NCT03518086) and LUCENT-2 (NCT03524092) phase 3 trials.

Aims & Methods

Bowel urgency severity was assessed using the Urgency Numeric Rating Scale (UNRS; 0=no urgency to 10=worst possible urgency). Bowel urgency CMI is a ≥3-point decrease and bowel urgency remission is a UNRS score of 0 or 1². WPAI scores (absenteeism, presenteeism, and work productivity loss in employed patients, and activity impairment in all patients) were measured using a 6-item questionnaire; higher scores indicate greater impairment and less productivity. Mediation analyses were performed to separately examine the relative association between the direct effect of bowel urgency CMI and bowel urgency remission (predictor) and WPAI scores while adjusting for the potential confounding effects of RB remission and SF remission (mediator). Analyses were treatment agnostic and combined patients from mirikizumab and placebo groups from LUCENT-1 (N=1162) and LUCENT-2 (N=544) trials.

Results

At week (W)12 and W52, the direct effect of bowel urgency remission accounted for 43%–49% and 27%–57% of the improvement in all WPAI domain scores except absenteeism, respectively. The association values greater than 100% at W12 and W52 (153% and 148%, respectively) reflect the critical importance of SF remission in the improvement of absenteeism score. Bowel urgency CMI resulted in the largest proportion of improvement in WPAI domain scores (except absenteeism) at W12 (71%–74%) and W52 (66%–78%). Bowel urgency CMI accounted for 68% and 239% of the improvement in absenteeism scores at W12 and W52, respectively. At W52, 750% of the effect was mediated by RB remission.

Conclusion

Improvement in work productivity and regular activities were primarily ascribed to bowel urgency remission or bowel urgency CMI relative to RB remission and SF remission in patients with moderately-to-severely active UC. These findings suggest that bowel urgency is a critical and independent symptom that considerably impacts patients’ productivity.

Introduction

Inflammatory bowel disease (IBD), a chronic inflammatory disease of the gastrointestinal tract, is caused by various factors, including genetic factors and environmental factors, as well as dysregulated immune responses. LMT503, a novel organic small-molecule compound, has the potential to suppress pro-inflammatory cells and induce anti-inflammatory cells by modulating their cell metabolisms. We evaluated the anti-inflammatory effects of LMT503 in a murine adoptive T cell transfer-induced colitis model.

Aims & Methods

This study was conducted to evaluate the anti-inflammatory effect of LMT503 in the murine chronic colitis model. Naïve CD4⁺CD25^-CD45RB^high CD62L^high T cells that were isolated from wild-type mice by flow cytometry based-method and transferred to Rag1 knock-out mice by intraperitoneal injection to induce murine adoptive T cell transfer-induced colitis. LMT503 was orally administrated (50mg/kg, 100mg/kg) for 2 weeks starting at 5 weeks after naïve T cell transfer. The disease activity index (DAI) was checked daily, and histopathological score, macroscopic injury score, and colon length were evaluated upon sacrifice. Macrophages and T cells from the spleen were analyzed by flow cytometry. Gene expression in colon tissue was measured by qRT-PCR and cytokine profiles in plasma was measured by cytometric bead array. Myeloperoxidase (MPO) activity was measured using the MPO activity kit.

Results

Oral administration of LMT503 ameliorated adoptive T cell transfer-induced colitis in mice. The DAI, histopathological score, and macroscopic injury score were significantly decreased after the administration of LMT503 in a dose-dependent manner. The LMT503-treated group showed significantly increased mucin production in the colon. Th1, Th17 cells, and M1 macrophages in the spleen were suppressed, and M2 macrophages were induced by the administration of LMT503. MPO activity and gene expressions of pro-inflammatory cytokines, such as IL-6, IL-1β, and TNF-α, in colon tissue were suppressed by the administration of LMT503. And the level of inflammatory cytokines, such as IL-2, TNF-α, and IFN-γ, in plasma were significantly suppressed by the administration of LMT503. Especially, LMT503 treatment significantly increased the gene expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (Ppargc1a), a master regulator of mitochondrial biogenesis, suggesting that LMT503 modulates cellular metabolism towards an anti-inflammatory metabolism.

Conclusion

Our data suggest that the anti-inflammatory effect of LMT503 ameliorates murine adoptive T cell transfer-induced colitis by modulating cellular metabolism and immune cell modulation. Therefore, LMT503 may be a novel therapeutic drug that opens new avenues for the treatment of IBD.
