RESUMEN

BACKGROUND AND AIMS: Dysphagia is the hallmark symptom in eosinophilic esophagitis (EoE). However, data are limited regarding the overall prevalence and potential implications of atypical symptoms like odynophagia and retrosternal pain. METHODS: Patients enrolled into the Swiss EoE cohort study (SEECS) were analyzed regarding the presence of odynophagia and retrosternal pain. Demographics, other EoE-related symptoms, histologic and endoscopic activity were compared between EoE-patients with vs. without odynophagia and/or retrosternal pain. RESULTS: 474 patients (75.2% male) were analyzed. In their individual course of disease 110 (23.2%) patients stated to have ever experienced odynophagia and 64 (13.5%) retrosternal pain independent of food intake, 24 (5%) patients complained about both symptoms. Patients with odynophagia consistently scored higher in symptom severity (p < 0.001), EREFS score (median 3.0 vs. 2.0, p = 0.006), histologic activity and a lower quality of life (p = 0.001) compared to patients without odynophagia. Sex, age at diagnosis, EoE-specific treatment, complications such as candida or viral esophagitis and disease duration were similar in patients with vs. without odynophagia. Also patients with retrosternal pain scored higher in symptom severity (2.0 vs. 1.0, p = 0.001 and 2.0 vs. 1.0, p < 0.001 in physician and patient questionnaire assessment, respectively). However, there was neither a difference in endoscopic/histologic disease activity nor in quality of life according to presence or absence of retrosternal pain. Due to logistic reasons, a stratification regarding the presence of concomitant dysphagia was not possible. CONCLUSION: Odynophagia and swallowing-independent retrosternal pain are common symptoms in patients with EoE, associate with an overall higher EoE-related symptom severity and for the case of odynophagia lower quality of life. However, the influence of concomitant dysphagia and its severity remains unclear and needs to be included in future analyses.

RESUMEN

Introduction: The Swiss Eosinophilic Esophagitis Cohort Study (SEECS) is a national cohort that was established in 2015 with the aim of improving quality of care of affected adults with eosinophilic esophagitis (EoE). Between 2020 and 2022, paper questionnaires were gradually replaced by fully electronic data capture using Research Electronic Data Capture (REDCap®) software. We aim to provide an update of the SEECS 8 years after its launch. Methods: The SEECS prospectively includes adults (≥18 years of age) with EoE as well as patients with gastroesophageal reflux disease (GERD) and healthy control subjects (HC). Upon inclusion and follow-up (typically once every 12-18 months), patients and physicians complete REDCap® questionnaires, which are available in German, French, and English. Patient-reported outcomes (PROs) and biologic findings are assessed on the same day using validated instruments (EEsAI PRO for symptoms; EoE-QoL-A for QoL; EREFS for endoscopic activity; modified EoE-HSS for histologic activity). The SEECS biobank includes biosamples from patients with EoE, GERD, and HC. Results: As of July 2023, the SEECS included 778 patients (716 [92%] with EoE, 29 [3.8%] with GERD, and 33 [4.2%] HC; 559/778 [71.9%] were male). Mean age ± SD (years) at enrollment according to diagnosis was as follows: EoE 41.9 ± 12.9, GERD 53.6 ± 16.4, HC 51.7 ± 17.2. Concomitant GERD was found in 200 patients (27.9%) of the EoE cohort. Concomitant allergic disorders (asthma, rhinoconjunctivitis, eczema) were present in 500 EoE patients (74.4%). At inclusion, 686 (95.8%) of EoE patients were on ongoing treatment (orodispersible budesonide tablet [Jorveza®] in 281 patients [41%]; budesonide or fluticasone syrup or swallowed powder in 290 patients [42.3%]; proton-pump inhibitors in 162 patients [23.6%]; elimination diets in 103 patients [15%]; and esophageal dilation at last visit in 166 patients [24.2%]). A total of 8,698 biosamples were collected, of which 1,395 (16%) were used in the framework of translational research projects. Conclusion: SEECS continuously grows and is operational using fully electronic data capture. SEECS offers up-to-date epidemiologic and real-world clinical efficacy data on EoE and promotes clinical and translational research.

RESUMEN

The genetic background of inflammatory bowel disease, both Crohn's disease and ulcerative colitis, has been known for more than 2 decades. In the last 20 years, genome-wide association studies have dramatically increased our knowledge on the genetics of inflammatory bowel disease with more than 200 risk genes having been identified. Paralleling this increasing knowledge, the armamentarium of inflammatory bowel disease medications has been growing constantly. With more available therapeutic options, treatment decisions become more complex, with still many patients experiencing a debilitating disease course and a loss of response to treatment over time. With a better understanding of the disease, more effective personalized treatment strategies are looming on the horizon. Genotyping has long been considered a strategy for treatment decisions, such as the detection of thiopurine S-methyltransferase and nudix hydrolase 15 polymorphisms before the initiation of azathioprine. However, although many risk genes have been identified in inflammatory bowel disease, a substantial impact of genetic risk assessment on therapeutic strategies and disease outcome is still missing. In this review, we discuss the genetic background of inflammatory bowel disease, with a particular focus on the latest advances in the field and their potential impact on management decisions.

RESUMEN

INTRODUCTION: It is still unknown whether eosinophilic esophagitis (EoE) patients with localized disease are different from those with extended disease. METHODS: We evaluated prospectively included patients in the Swiss EoE cohort. Data on all patients with active disease at baseline, no concomitant gastroesophageal reflux disease, no strictures at baseline, and at least one follow-up visit were analyzed. We compared patients with histologically localized proximal versus distal versus extended (=proximal and distal) disease with regard to patient, disease characteristics, disease presentation, and development of complications. RESULTS: We included 124 patients with a median of 2.5 years of follow-up (73.4% males, median age 35.0 years). Ten patients had proximal (8.1%), 46 patients had distal (37.1%), and 68 patients had extended disease (54.8%). Patients with proximal disease were significantly more often females (80%) compared with patients with distal (26.1%, p = 0.002) or extended disease (19.1%, p < 0.001) and reported less severe symptoms (VAS 0 vs. VAS 1, p = 0.001). Endoscopic and histological disease was less pronounced in the proximal esophagus of proximal EoE compared to extended disease (EREFS 1.0 vs. 3.0, p = 0.001; 27.0 eos/hpf vs. 52.5 eos/hpf, p = 0.008). Patients with proximal disease were less likely to undergo dilation compared to patients with distal disease in the follow-up (3.3% vs. 23.3%, p = 0.010). In a multivariate Cox regression model, proximal eosinophilia was less likely to be associated with treatment failure compared to distal eosinophilia. CONCLUSION: Although isolated proximal EoE is infrequent, it is associated with less severe disease and better disease outcome. Proximal disease appears to present a unique EoE phenotype.

RESUMEN

Background: While the detrimental impact of negative emotions on the clinical course of inflammatory bowel disease (IBD) and quality of life has been extensively investigated, evidence for a potential impact of positive emotions is scarce. Objectives: We aim to analyse contributing factors of positive affect and their predictive value for disease course in IBD patients. Design: In this retrospective cohort study, epidemiological, psychosocial and IBD disease characteristics of Swiss IBD cohort study patients were analysed longitudinally. Methods: Epidemiological, psychosocial and disease characteristics were extracted from the database of the Swiss IBD cohort study. Participants' positive emotions were assessed cross-sectionally with the seven-item Marburg questionnaire (range 1-6) addressing positive affect in different aspects of daily life. Predictors of positive emotions were identified by linear regression. The quantitative longitudinal impact of positive emotions on the further disease course was analysed using a multivariable Cox proportional hazards model. Results: Among 702 IBD patients, those reporting more positive emotions were found to have significantly less intense medical treatment, less pain and fewer depressive symptoms (p < 0.05). A higher percentage of variability in positive emotions was explained by pain (36%) and depressive symptoms (13%) than by epidemiological characteristics (0.3%), or characteristics of IBD and its treatment (2.4%). Patients with higher levels of positive emotions (score > 3.5) experienced longer flare-free survival, also after adjusting for confounders (adjusted hazard ratio: 0.39, p < 0.05). Conclusions: The absence of pain and depressive symptoms were the strongest drivers for high positive affect. Higher scores of positive affect were associated with longer disease-free survival in IBD patients.

RESUMEN

INTRODUCTION: There is a complex interrelationship between gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) potentially promoting the occurrence and modulating severity of each other reciprocally. Presence of Barrett's esophagus (BE) is a defining factor for the diagnosis of GERD. While several studies investigated the potential impact of concomitant GERD on the presentation and course of EoE, little was known with regards to BE in EoE patients. METHODS: We analyzed prospectively collected clinical, endoscopic, and histological data from patients enrolled in the Swiss Eosinophilic Esophagitis Cohort Study (SEECS) regarding differences between EoE patients with (EoE/BE+) versus without BE (EoE/BE-) and determined the prevalence of BE in EoE patients. RESULTS: Among a total of 509 EoE patients included in our analysis, 24 (4.7%) had concomitant BE with a high male preponderance (EoE/BE+ 83.3% vs. EoE/BE- 74.4%). While there were no differences in dysphagia, odynophagia was significantly (12.5 vs. 3.1%, p = 0.047) more common in EoE/BE+ versus EoE/BE-. General well-being at last follow-up was significantly lower in EoE/BE+. Endoscopically, we observed an increased incidence of fixed rings in the proximal esophagus in EoE/BE+ (70.8 vs. 46.3% in EoE/BE-, p = 0.019) and a higher fraction of patients with a severe fibrosis in the proximal histological specimen (8.7 vs. 1.6% in EoE/BE, p = 0.017). CONCLUSION: Our study reveals that BE is twice as frequent in EoE patients compared to general population. Despite many similarities between EoE patients with and without BE, the finding of a more pronounced remodeling in EoE patients with Barrett is noteworthy.

RESUMEN

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease of the esophagus with increasing incidence and dysphagia as the main symptom. The management of suspected or known EoE by Austrian endoscopists has not been investigated yet. METHODS: A web-based survey with 13 questions about the management of EoE was sent to endoscopists via the Austrian Society of Gastroenterology and Hepatology (ÖGGH). RESULTS: A total of 222 endoscopists (74% gastroenterologists, 23% surgeons, and 2% pediatricians; 68% working in a hospital) from all 9 states participated. In patients with dysphagia but a normal appearing esophagus, 85% of respondents reported always taking biopsies; however, surgeons were less likely to obtain biopsies compared to gastroenterologists ("always" 69% vs. 90%, "sometimes" 29% vs. 10%, "never" 2% vs. 0%, p < 0.001). The approved budesonide orodispersible tablet is the preferred first-line drug used in EoE, ahead of proton pump inhibitors (PPI). Only 65% of participants monitor the patients by endoscopy and histology after 12 weeks of induction therapy, 26% do not continue maintenance therapy, and 22% monitor patients only when symptomatic. CONCLUSION: The vast majority of Austrian endoscopists adhere to the European and US guidelines in cases of suspected EoE. In contrast, despite the chronic disease course, a significant percentage of providers indicate not to use maintenance therapy and monitor the patients routinely.

RESUMEN

BACKGROUND: Various environmental risk factors have been associated with the pathogenesis of inflammatory bowel disease. In this study we aimed to identify lifestyle factors that affect the onset of Crohn's disease and ulcerative colitis. METHODS: 2294 patients from the Swiss IBD Cohort Study received a questionnaire regarding physical activity, nutritional habits and status of weight. In addition, a control group was formed comprising patients' childhood friends, who grew up in a similar environment. RESULTS: Overall, 1111 questionnaires were returned (response rate: 48.4%). Significantly more patients with inflammatory bowel disease reported no regular practice of sport during childhood and beginning of adulthood compared to the control group (p = 0.0001). No association between intake of refined sugar and onset of inflammatory bowel disease was observed. More patients with Crohn's disease compared to ulcerative colitis and controls suffered from overweight during childhood (12.8% vs. 7.7% and 9.7%, respectively; p = 0.027). CONCLUSIONS: Our study underlines the relevance of environmental factors in the development of inflammatory bowel disease. Our results imply a protective effect of physical activity regarding the onset of inflammatory bowel disease.

RESUMEN

BACKGROUND: Inflammatory bowel disease (IBD) care and education might differ around Europe. Therefore, we conducted this European Variation In IBD PracticE suRvey (VIPER) to investigate potential differences between countries. METHODS: This trainee-initiated survey, run through SurveyMonkey®, consisted of 47 questions inquiring basic demographics, IBD training, and clinical care. Results were compared according to gross domestic product (GDP) per capita, for which countries were divided into 2 groups (low/high income, according to the World Bank). RESULTS: The online survey was completed by 1,285 participants from 40 European countries, with a majority of specialists (65.3%) working in academic institutions (50.4%). Significant differences in IBD-specific training (55.9% vs. 38.4%), as well as availability of IBD units (58.4% vs. 39.7%) and multidisciplinary meetings (73.2% vs. 40.1%), were observed between respondees from high and low GDP countries (p < 0.0001). In high GDP countries, IBD nurses are more common (85.9% vs. 36.0%), also mirrored by more nurse-led IBD clinics (40.6% vs. 13.7%; p < 0.0001). IBD dieticians (33.4% vs. 16.5%) and psychologists (16.8% vs. 7.5%) are mainly present in high GDP countries (p < 0.0001). In the current COVID era, telemedicine is available in 73.2% versus 54.1% of the high/low GDP countries, respectively (p < 0.0001). Treat-to-target approaches are implemented everywhere (85.0%), though access to biologicals and small molecules differs significantly. CONCLUSION: Much variability in IBD practice exists across Europe, with marked differences between high and low GDP countries. Further work is required to help address some of these inequalities, aiming to improve and standardize IBD care and training across Europe.

RESUMEN

Background and Aims: Delirium is the most common acute neuropsychiatric syndrome in hospitalized patients. Higher age and cognitive impairment are known predisposing risk factors in general hospital populations. However, the interrelation with precipitating gastrointestinal (GI) and hepato-pancreato-biliary (HPB) diseases remains to be determined. Patients and methods: Prospective 1-year hospital-wide cohort study in 29'278 adults, subgroup analysis in 718 patients hospitalized with GI/HPB disease. Delirium based on routine admission screening and a DSM-5 based construct. Regression analyses used to evaluate clinical characteristics of delirious patients. Results: Delirium was detected in 24.8% (178/718). Age in delirious patients (median 62 years [IQR 21]) was not different to non-delirious (median 60 years [IQR 22]), p = 0.45). Dementia was the strongest predisposing factor for delirium (OR 66.16 [6.31-693.83], p < 0.001). Functional impairment, and at most, immobility increased odds for delirium (OR 7.78 [3.84-15.77], p < 0.001). Patients with delirium had higher in-hospital mortality rates (18%; OR 39.23 [11.85-129.93], p < 0.001). From GI and HPB conditions, cirrhosis predisposed to delirium (OR 2.11 [1.11-4.03], p = 0.023), while acute renal failure (OR 4.45 [1.61-12.26], p = 0.004) and liver disease (OR 2.22 [1.12-4.42], p = 0.023) were precipitators. Total costs were higher in patients with delirium (USD 30003 vs. 10977; p < 0.001). Conclusion: Delirium in GI- and HPB-disease was not associated with higher age per se, but with cognitive and functional impairment. Delirium needs to be considered in younger adults with acute renal failure and/or liver disease. Clinicians should be aware about individual risk profiles, apply preventive and supportive strategies early, which may improve outcomes and lower costs.

RESUMEN

BACKGROUND: Little is known about the impact of ostomy formation in inflammatory bowel disease patients on course of disease, psychological well-being, quality of life and working capacity. METHODS: We analyzed patients over a follow-up of up to 16 years in the Swiss inflammatory bowel disease cohort study (SIBDCS) with prospective data collection. We compared Ulcerative colitis and Crohn's disease patients with and without ostomy as well as permanent and closed stoma formation before and after surgery, investigating disease activity, psychological wellbeing and working capacity in a case-control design. RESULTS: Of 3825 SIBDCS patients, 176 with ostomy were included in the study and matched with 176 patients without ostomy using propensity score, equaling 352 patients for the analysis. As expected, we observed a lower mean and maximal disease activity in patients after stoma surgery compared with control patients without stoma. Overall, psychological wellbeing in patients with stomas vs. controls as well as patients with permanent vs. closed stoma was similar in terms of disease-specific quality of life (total score of the Inflammatory Bowel Disease Quality of Life questionnaire), psychological distress (total score of the Hospital Anxiety and Depression Scale), and stress at work (effort-reward-imbalance ratio), with the exception of a higher Posttraumatic Diagnostic Scale total score in patient with vs. without stoma. Compared to IBD patients without stoma, the adverse impact on working capacity in overall stoma IBD patients appeared to be modest. However we observe a significantly higher reduction in working capacity in permanent vs. closed stoma in CD but not UC patients. CONCLUSION: As to be expected, IBD patients may benefit from closed and permanent stoma application. Stoma surgery appears to only modestly impact working capacity. Importantly, stoma surgery was not associated with adverse psychological outcomes, with comparable psychological well-being regardless of presence and type of stoma.

RESUMEN

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic progressive disease. Diagnostic delay (DD) is associated with increased risk of esophageal strictures and food impactions. We aimed to assess the evolution of DD since the first description of EoE in 1993 until 2021. METHODS: We analyzed data from patients prospectively included in the Swiss EoE database. DD was calculated as the time interval between the first occurrence of EoE symptoms and the confirmed diagnosis. DD was analyzed annually over time (1989-2021) and according to milestone publications in the field (1993: first description; 2007: first consensus recommendations; and 2011: updated consensus recommendations). In addition, a Cox proportional hazards model has been used to describe the relation between DD and covariates. RESULTS: Complete data of 1,152 patients (857 male [74%]; median age at diagnosis: 38 years, interquartile range: 28-49, range: 1-86) were analyzed. Overall, median DD was 4 years (interquartile range: 1-11, range, 0-56), with DD ≥ 10 years in 32% of the population. Over time, DD did not significantly change, neither annually nor according to release dates of milestone publications with a persistently stable fraction of roughly one-third of all patients with a DD of ≥10 years. Both ages at diagnosis ( P < 0.001, with an increase in DD up to the age of 31-40 years) and at symptom onset (younger patients had a longer DD; P < 0.001) were significantly associated with DD. DISCUSSION: DD has not changed since the first description of EoE almost 30 years ago and remains substantial. Even today, one-third of patients have a persistently high DD of ≥10 years. Substantial efforts are warranted to increase awareness for EoE and its hallmark symptom, solid food dysphagia, as an age-independent red-flag symptom among healthcare professionals and presumably the general population alike to lower risk of long-term complications.

RESUMEN

BACKGROUND: The bidirectional "gut-brain axis" has been implicated in the pathogenesis of inflammatory bowel diseases (IBD). While the influence of stress and depressive symptoms on IBD is well-characterized, the role of personality remains insufficiently investigated. METHODS: Personality was assessed in 1154 Swiss IBD cohort study (SIBDCS) patients via the NEO-Five-Factor Inventory (NEO-FFI) as well as in 2600 participants of the population-based CoLaus¦PsyCoLaus cohort study (NEO-FFI-revised). The NEO-FFI subcomponents activity, self-reproach and negative affect were associated with higher IBD disease activity and were combined to a NEO-FFI risk score. This risk score was validated and its effect on clinical IBD course and psychological endpoints was analysed in time-to-event and cumulative incidence analyses. RESULTS: In time-to-event analyses, a high NEO-FFI risk score was predictive for the clinical endpoints of new extraintestinal manifestation [EIM, adjusted hazard ratio (aHR) = 1.64, corrected p value (q) = 0.036] and two established composite flare endpoints (aHR = 1.53-1.63, q = 0.003-0.006) as well as for the psychological endpoints depressive symptoms (aHR = 7.06, q < 0.001) and low quality of life (aHR = 3.06, q < 0.001). Furthermore, cumulative incidence analyses showed that patients at high NEO-FFI risk experienced significantly more episodes of active disease, new EIMs, one of the flare endpoints, depressive episodes and low disease-related quality of life. Personalities of IBD patients showed only minor differences from the general population sample (Pearson's r = 0.03-0.14). CONCLUSIONS: Personality assessed by the NEO-FFI contained considerable predictive power for disease recurrence, depressive symptoms and low quality of life in IBD patients. Nevertheless, the personalities of IBD patients did not substantially differ from the general population.

RESUMEN

BACKGROUND AND AIMS: No recommendations exist regarding optimal follow-up schedule in patients with eosinophilic esophagitis (EoE) under maintenance treatment. METHODS: We retrospectively evaluated a long-term surveillance concept at the Swiss EoE clinic, where clinical, endoscopic and histological disease activity is assessed annually regardless of EoE symptoms. Data on 159 adult patients under maintenance steroid treatment with available follow-up were analyzed. Patients were classified as having close (duration between visits <18 months) or non-close follow-up (≥18 months). RESULTS: We analyzed a total of 309 follow-up visits of 159 patients (123 males, age at diagnosis 38.9 ± 15.4 years). 157 (51%) visits were within a close follow-up schedule (median duration between visits of 1.0 years (interquartile range (IQR) 0.9-1.2)), while 152 visits (49%) were not (median duration between visits 2.9 years (IQR 2.0-4.1)). There was no difference regarding ongoing clinical, endoscopic, and histological disease activity, and adherence to prescribed steroid treatment between the two groups. However, stricture formation was significantly less frequently observed at visits within a close follow-up schedule (22.9 vs. 33.6%, p = 0.038). Absence of close follow-up was a significant risk factor for stricture development in a multivariate regression model. Patients who achieved histological remission and were followed within a close-follow-up schedule had significantly earlier detection of histological relapse compared to patients not within such close follow-up. CONCLUSION: Close follow-up is associated with fewer stricture formation and appears to result in earlier detection of histological relapse in patients with eosinophilic esophagitis. We advocate for regular assessment of disease activity (every 12-18 months) in order to detect relapsing disease as early as possible, and therefore potentially minimize the risk for EoE complications.

RESUMEN

BACKGROUND: Tumor necrosis factor (TNF) inhibitors have improved treatment of ulcerative colitis (UC), but loss of response remains a frequent problem. The anti-TNF agent, golimumab, was approved in Switzerland for the treatment of UC in 2014. This study aims to summarize the experience of golimumab in a real-world setting in Switzerland. METHODS: We analyzed real-world data from 1769 UC patients from the Swiss Inflammatory Bowel Disease Cohort (SIBDC) study and performed a chart review of golimumab-treated patients. We extracted the partial Mayo score at t0 (baseline), t1 (2-16 weeks), t2 (17-35 weeks), and t3 (36-89 weeks). The primary endpoint was clinical response at t1, defined as marked improvement in partial Mayo score and objective parameters. Clinical remission was defined as resolution of symptoms and normalization of objective parameters. RESULTS: Our chart review included 103 UC patients with golimumab treatment (5.8% of all SIBDC UC patients); only 16 (15.5%) were anti-TNF naïve. Sixty-three patients remained on golimumab (61.2%) after 180 days, 51 (44.7%) after 365 days, and 34 (33%) after 630 days after the start of treatment. Upon golimumab treatment, the partial Mayo score decreased from 4 [interquartile range (IQR): 2-6] at t0 to 2 (IQR: 0-4) at t1, 1 (IQR: 0-3.5) at t2, and 1 (IQR: 0-3) at t3 (p < 0.001 for all comparisons with t0). The primary endpoint, clinical response at t1, could be evaluated in 52 patients and was met in 15 individuals (28.8%). Clinical remission at t1 was observed in 8 out of 52 patients (15.4%). Golimumab was generally well tolerated, one patient developed meningitis. The most frequent reasons to stop treatment were primary and secondary non-response. CONCLUSION: Golimumab was used in 5.8% of Swiss UC patients, mainly in biologic-experienced individuals. Golimumab treatment was associated with a sustained reduction of symptoms and clinical response in approximately 30% of patients.[ClinicalTrials.gov identifier: NCT00488631].

RESUMEN

Eosinophilic esophagitis (EoE) is the most common cause of esophageal food impaction (EFI). Approaches to management of EFI due to EoE have not been well characterized. We conducted a web-based survey to understand approaches to management of EFI due to EoE among endoscopists. Questions focused on management of patients from presentation to post-endoscopy follow-up. The survey was administered to a list of eligible candidates provided by societies of gastroenterology. A total of 308 endoscopists completed the questionnaire. The majority (83%) practiced in Europe and treated adults (78%). Most agreed patients should be advised to seek emergency care (66%) within 1 to 2 hours (41% agreement). There was agreement that medications to induce vomiting should be avoided (84%) and that blood tests or imaging studies were usually not required before endoscopy. By contrast, there was more variability in the type of sedation recommended and the need for endotracheal intubation, especially when comparing more experienced with less experienced EoE-endoscopists. Overall, fewer than half (43%) respondents recommended obtaining esophageal biopsies during the initial endoscopy. However, there were significant differences in the proportion who recommended biopsies based on level of EoE-experience (25, 52, 77%, P < 0.001; less vs. moderate vs. very experienced) and comparing pediatric and adult endoscopists (32, vs. 79%, P < 0.001; adult vs. pediatric). There exists heterogeneity among endoscopists in recommendations to manage EFI in patients with EoE. These findings support development of clinical guidelines and new studies to clarify the rationale for best practices. Key summary: Established knowledge-The optimal management of patients with esophageal food impaction due to eosinophilic esophagitis from presentation at the emergency department to postendoscopy care is unclear. New findings-Considerable recommendation variation exists in the management of EFI in patients with EoE. Our findings provide a rationale for the creation of consensus practice guidelines and further study into best practices.

RESUMEN

BACKGROUND: Inflammatory bowel disease (IBD) patients are at high risk for depression, and depression has been shown to affect disease course. We examined interrelations between depression, genetic risk factors for depression, and IBD flares. METHOD: In 1973 patients (1137 Crohn's disease, 836 ulcerative colitis) of the Swiss IBD Cohort Study (SIBDCS), depressive status (hospital anxiety and depression subscale for depression, HADS-D ≥11) was assessed on a yearly basis. We investigated the impact of depression on IBD-relevant clinical outcomes in Cox proportional hazards models. We used active disease (CDAI ≥150 or MTWAI ≥10) and 2 published composite flare definitions-FNCE (physician-reported flare, nonresponse to therapy, new complication, or extraintestinal manifestation) and AFFSST (active disease, physician-reported flare, fistula, stenosis, and new systemic therapy)-as clinical end points. Additionally, 62 preselected single nucleotide polymorphisms (SNPs) were screened for cross-sectional associations with depression, and if present, their predictive value for future depression and clinical deterioration was assessed. RESULTS: Depression was a strong risk factor for disease-related end points, including active disease (adjusted hazard ratio [aHR], 3.55; P < 0.001), AFFSST (aHR, 1.62; P < 0.001), and FNCE (aHR, 1.35; P = 0.019). The SNP rs2522833 was significantly associated with depression at enrollment (q = 0.059). The TC allele of rs588765 was negatively associated with the presence of depression at enrollment (q = 0.050) and after enrollment (aHR, 0.67; P = 0.035) and with fewer active disease states (aHR, 0.72; P = 0.045) during follow-up. CONCLUSION: In IBD, depressive symptoms and inflammatory activity are intimately related. Depressive symptoms were a strong predictor of clinical deterioration, and genetic markers may play a role in this relationship.
