RESUMO
BACKGROUND AND AIMS: Eosinophilic oesophagitis (EoE) is characterised by symptoms of esophageal dysfunction and oesinophil tissue infiltration. The EoE Diagnostic Panel (EDP) can distinguish between active and non-active EoE using a set of 77 genes. Recently, the existence of distinct EoE variants featuring symptoms similar to EoE, such as oesophageal dysfunction but lacking eosinophil infiltration, had been determined. METHODS: We used oesophageal biopsies from patients with histologically active (n=10) and non-active EoE (n=9) as well as from healthy oesophageal controls (n=5) participating in the Swiss Eosinophilic Esophagitis Cohort Study (SEECS) and analysed the gene expression profile in these biopsies by total RNA-sequencing (RNA-seq). Moreover, we employed the publicly accessible RNA-seq dataset (series GSE148381) as reported by Greuter et al, encompassing a comprehensive genomic profile of patients presenting with EoE variants. RESULTS: A novel, diagnostic gene expression panel that can effectively distinguish patients with histologically active conventional EoE from patients with EoE in histological remission and control individuals, and from three newly discovered EoE variants was identified. Histologically Active EoE Diagnostic Panel (HAEDP) consists of 53 genes that were identified based on differential expression between histologically active EoE, histological remission and controls (p≤0.05). By combining the HAEDP with EDP, we expanded our knowledge about factors that may contribute to the inflammation in EoE and improved our understanding of the underlying mechanisms of the disease. Conversely, we suggested a compact group of genes common to both HAEDP and EDP to create a reliable diagnostic tool that might enhance the accuracy of EoE diagnosis. CONCLUSION: We identified a novel set of 53 dysregulated genes that are closely associated with the histological inflammatory activity of EoE. In combination with EDP, our new panel might be a valuable tool for the accurate diagnosis of patients with EoE as well as for monitoring their disease course.

BACKGROUND: Shorter half-life glucagon-like peptide-1 receptor agonists (GLP-1 RAs) delay gastric emptying (DGE) more than GLP-1 RAs with longer half-lives. DGE is a known risk factor for gastro-oesophageal reflux disease (GERD) and its complications. AIM: To determine whether short-acting or long-acting GLP-1 RAs are associated with an increased risk of new GERD or GERD-related complications DESIGN: We used the TriNetX global database to identify adult patients with type 2 diabetes mellitus and generated two cohorts totalling 1 543 351 patients on (1) GLP-1 RA or (2) other second-line diabetes medication. Using propensity-score matching, Kaplan-Meier Analysis and Cox-proportional hazards ratio (HR), we analysed outcomes and separately examined outcomes in patients starting short-acting (≤1 day) and long-acting (≥5 days) GLP-1 RAs. RESULTS: 177 666 patients were in each propensity-matched cohort. GLP-1 RA exposure was associated with an increased risk (HR 1.15; 95% CI 1.09 to 1.22) of erosive reflux disease (ERD). However, this was solely due to short-acting (HR 1.215; 95% CI 1.111 to 1.328), but not long-acting (HR 0.994; 95% CI 0.924 to 1.069) GLP-1 RA exposure. Short-acting GLP-1 RAs were also associated with increased risk of oesophageal stricture (HR 1.284; 95% CI 1.135 to 1.453), Barrett's without dysplasia (HR 1.372; 95% CI 1.217 to 1.546) and Barrett's with dysplasia (HR 1.505; 95% CI 1.164 to 1.946) whereas long-acting GLP-1 RAs were not. This association persisted in sensitivity analyses, and when individually examining the short-acting GLP-1 RAs liraglutide, lixisenatide and exenatide. CONCLUSION: Starting shorter-acting GLP-1 RAs is associated with increased risks of GERD and its complications.

PURPOSE OF REVIEW: This review seeks to understand novel avenues for eosinophilic GI disease management. Biomarkers offer a unique and non-invasive approach to tracking EoE disease progression. While no biomarkers have definitively met the diagnostic criteria for eosinophilic GI diseases, some biomarkers have been shown to be associated with disease activity. Here, we examine the potential of recently studied biomarkers. RECENT FINDINGS: Current research shows advancements in blood, luminal fluid, and breath testing. Particular areas of interest include mRNA analyses, protein fingerprinting, amplicon sequence variants (ASVs), T cells and IgE receptors, eosinophilic cationic proteins, cytokines, and nitric oxide exhalation. Preliminary results showed that mucosal biomarkers, directly captured from the esophagus, may reflect the best representation of biopsy-based results, in contrast to biomarkers obtained from indirect or peripheral (blood, breath) methods. However, this is based on limited clinical studies without sufficient numbers to evaluate true diagnostic accuracy. Large-scale randomized trials are needed to fully ascertain both the optimal sampling technique and the specific biomarkers that reflect diagnostic status of the disease.

BACKGROUND: Food bolus obstruction (FBO) leading to hospital treatment is often associated with eosinophilic oesophagitis (EoE), stenosis, or oesophageal cancer (1). Danish national guidelines recommend that patients with FBO undergo a diagnostic upper endoscopy within two weeks of presentation to exclude possible malignancy, and histological evaluation of eight biopsies (2, 3). AIMS: The aims of this study were to (1) report the incidence and describe the causes and treatment of FBO in the North Denmark Region (NDR), (2) determine the proportion of patients who underwent upper endoscopy and biopsy according to regional and national guidelines, and (3) identify International Classification of Diseases 10th Revision (ICD-10) diagnosis and procedure codes applied to the hospital visits due to FBO in the NDR. METHODS: Among all acute hospital visits in the NDR in 2021, all visits with ICD-10 codes possibly reflecting FBO, as well as a random sample of 14,400 visits with unspecific ICD-10 codes (R and Z codes), were screened manually for possible FBO. Diagnosis, follow-up, and treatment of all patients with FBO were recorded. RESULTS: The median patient age was 66.0 (Q1-Q3: 49.8-81.0) years, and half of the patients had experienced FBO before. Two thirds of patients (66.0%) were never diagnosed with a cause of FBO, followed by 17.3% with EoE. 30% of patients did not undergo upper endoscopy within two weeks of the hospital visit, and 50.7% were never biopsied in the oesophagus. Of 1886 hospital visits with registry ICD-10 codes that possibly reflected FBO, 8.4% were due to FBO, while FBO was present in 0.028% of the random sample of unspecific ICD-10 codes. CONCLUSIONS: Most hospitalized FBO patients in the NDR in 2021 were never diagnosed with a cause. In these patients there is a high risk of overlooked EoE or upper gastrointestinal cancers. The area needs immediate focus and changed routines to improve treatment and prevent new FBO.

INTRODUCTION: Eosinophilic gastrointestinal disorders beyond eosinophilic esophagitis (non-EoE EGIDs) are rare chronic inflammatory disorders of the gastrointestinal (GI) tract. Diagnosis is based on clinical symptoms and histologic findings of eosinophilic inflammation after exclusion of a secondary cause or systemic disease. Currently, no guidelines exist for the evaluation of non-EoE EGIDs. Therefore, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force group to provide consensus guidelines for childhood non-EoE EGIDs. METHODS: The working group was composed of pediatric gastroenterologists, adult gastroenterologists, allergists/immunologists, and pathologists. An extensive electronic literature search of the MEDLINE, EMBASE, and Cochrane databases was conducted up to February 2022. General methodology was used in the formulation of recommendations according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to meet current standards of evidence assessment. RESULTS: The guidelines provide information on the current concept of non-EoE EGIDs, disease pathogenesis, epidemiology, clinical manifestations, diagnostic and disease surveillance procedures, and current treatment options. Thirty-four statements based on available evidence and 41 recommendations based on expert opinion and best clinical practices were developed. CONCLUSION: Non-EoE EGIDs literature is limited in scope and depth, making clear recommendations difficult. These consensus-based clinical practice guidelines are intended to assist clinicians caring for children affected by non-EoE EGIDs and to facilitate high-quality randomized controlled trials of various treatment modalities using standardized, uniform disease definitions.

BACKGROUND: Eosinophilic oesophagitis (EOE) is a known cause of food bolus obstruction (FBO) with rising incidence and prevalence. AIMS: To assess the rates of EOE in adult cases presenting with an FBO via prospective biopsy collection during index endoscopy. METHODS: Oesophageal FBO cases requiring gastroscopy between February 2014 and January 2021 at a single institution with a unified policy to perform biopsies on FBO cases were analysed using medical records, endoscopy and histology. Statistical analysis was undertaken to compare those with and without EOE as their final diagnosis, including the timing of oesophageal biopsy and the season that cases presented. RESULTS: One hundred ninety FBO presentations were analysed, 15 patients presented twice and one patient presented four times within the 7-year study period. Men represented 72% of cases. A total of 78% of cases had biopsies collected at an index or scheduled follow-up endoscopy. EOE was the cause of the FBO in 28% (53/190) of presentations. FBO secondary to EOE was more likely to occur in the spring and summer months (Australian September to March), with 39% (19 of 49) of cases presenting in spring attributable to EOE. CONCLUSION: EOE affects a significant proportion of patients presenting with FBO (28%); a high biopsy rate of 78% in FBO cases provides an opportunity for prompt diagnosis and treatment.

BACKGROUND: A low incidence of eosinophilic esophagitis (EoE) in children in the North Denmark Region (NDR) were measured in 2007-2017. Few of the children diagnosed before 2017 were treated to remission suggesting a lack of awareness. While there currently are no guidelines for treating EoE in Denmark, a new English guideline was published in 2022 renewing focus on the disease. OBJECTIVE: The aim of this study was to measure the difference of current Danish clinical practice for treatment and follow-up of EoE children in the NDR with the new English guideline from the British Society of Gastroenterology (BSG) and the British Society of Pediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN). METHODS: This retrospective, register-based DanEoE cohort study included 31 children diagnosed with EoE between 2007 and 2021 in NDR. Medical records were reviewed and information about treatment and follow-up were collected. RESULTS: In 32% of the children with EoE in the NDR, first-line treatment corresponded with the new English guideline. One in 6 children were never started on any treatment even though treatment always is recommended. Histologic evaluation within 12 weeks as recommended was performed in 13% of the children. CONCLUSIONS: In Denmark focus on improving EoE treatment and follow-up for children is needed, as there is a significant difference between current clinical practice and the recommendations in the new English guideline.

BACKGROUND: The prevalence between erosive tooth wear (ETW) in association with reflux oesophagitis (RO) has been reported. However, the severity of both diseases and the relationship between ETW and non-erosive reflux disease (NERD) is unclear. OBJECTIVES: The prevalence and severity of ETW were investigated in RO, NERD and healthy controls. METHODS: 135 patients with RO, 65 with NERD and 40 healthy controls were recruited for this case-control study. A modified tooth wear index was used to evaluate the prevalence and severity of ETW. Salivary secretion and buffer capacity were assessed prior to endoscopy. The prevalence and severity of ETW, saliva properties among each group were analysed using Pearson's chi-squared test. RESULTS: A total of 135 cases (56.3%) were categorised as the patient with ETW (55 with mild RO, 49 with severe RO and 31 with NERD). There was a significant relationship between the prevalence of RO and ETW, while there was no significant correlation between the prevalence of NERD and ETW. There was a significant difference related to the severity between RO and ETW. For salivary secretion, there was a significant difference between with and without ETW in patients with mild RO, severe RO and NERD. There was a significant difference between with and without ETW for salivary buffer capacity in patients with mild and severe RO. CONCLUSION: There was a significant association of the prevalence and severity between RO and ETW. Clinical signs such as ETW and salivary buffer capacity depended on the severity of RO.

BACKGROUND: Extrinsic factors for erosive tooth wear (ETW) have been widely reported, but the intrinsic factors for wear remain unclear. OBJECTIVES: The aim of this study was to evaluate the factors associated with the prevalence of ETW in patients with reflux oesophagitis (RO). To prevent severe ETW with RO, factors associated with severity of ETW were also evaluated. METHODS: A total of 270 patients with RO were recruited. A modified tooth wear index was used to evaluate the prevalence and severity of ETW. Salivary secretion and buffering capacity were assessed prior to endoscopy. Subjects were asked to complete a medical condition and oral self-care questionnaire. Univariate and multivariate analyses were employed to identify factors collectively associated with the prevalence and severity of ETW. RESULTS: A total of 212 cases were categorized as patients with ETW (148 with mild ETW and 64 with severe ETW). Multivariate analyses indicated that saliva secretion, severity of RO and proton pump inhibitor (PPI) resistance were associated with the prevalence of ETW, whereas age, BMI and severity of RO were associated with the severity of ETW. The odds ratio of saliva secretion and BMI were less than 1, meaning that higher saliva secretion resulted in a lower prevalence of ETW and lower BMI was associated with severe ETW. CONCLUSION: Saliva secretion, severity of RO and PPI resistance were associated with the prevalence of ETW, whereas age, BMI and severity of RO were associated with the severity of ETW. Lower saliva secretion and BMI were significant factors for ETW.

OBJECTIVE: Disruption of the epithelial barrier plays an essential role in developing eosinophilic oesophagitis (EoE), a disease defined by type 2 helper T cell (Th2)-mediated food-associated and aeroallergen-associated chronic inflammation. Although an increased expression of interleukin (IL)-20 subfamily members, IL-19, IL-20 and IL-24, in Th2-mediated diseases has been reported, their function in EoE remains unknown. DESIGN: Combining transcriptomic, proteomic and functional analyses, we studied the importance of the IL-20 subfamily for EoE using patient-derived oesophageal three-dimensional models and an EoE mouse model. RESULTS: Patients with active EoE have increased expression of IL-20 subfamily cytokines in the oesophagus and serum. In patient-derived oesophageal organoids stimulated with IL-20 cytokines, RNA sequencing and mass spectrometry revealed a downregulation of genes and proteins forming the cornified envelope, including filaggrins. On the contrary, abrogation of IL-20 subfamily signalling in Il20R2 -/- animals resulted in attenuated experimental EoE reflected by reduced eosinophil infiltration, lower Th2 cytokine expression and preserved expression of filaggrins in the oesophagus. Mechanistically, these observations were mediated by the mitogen-activated protein kinase (MAPK); extracellular-signal regulated kinases (ERK)1/2) pathway. Its blockade prevented epithelial barrier impairment in patient-derived air-liquid interface cultures stimulated with IL-20 cytokines and attenuated experimental EoE in mice. CONCLUSION: Our findings reveal a previously unknown regulatory role of the IL-20 subfamily for oesophageal barrier function in the context of EoE. We propose that aberrant IL-20 subfamily signalling disturbs the oesophageal epithelial barrier integrity and promotes EoE development. Our study suggests that specific targeting of the IL-20 subfamily signalling pathway may present a novel strategy for the treatment of EoE.

BACKGROUND: In North Denmark Region (NDR), the incidence of Eosinophilic Oesophagitis (EoE) among adults has increased following a new biopsy protocol in 2011, whereas data on the incidence of EoE among children is lacking. AIMS: To describe the incidence of EoE in children aged 0-17 in NDR as well as diagnostic delay, clinical manifestations, treatment and complications. METHODS: This retrospective, register-based DanEoE cohort study included 18 children diagnosed with EoE between 2007-2017 in NDR. Medical files were reviewed with attention to symptoms, reason for referral, disease progress, treatment, symptomatic and histological remission as well as diagnostic delay. RESULTS: The median incidence per year (2007-2017) was 0.86/100,000 children in NDR aged 0-17 years. The median diagnostic delay among children was four years and six months. Sixty percent presented with food impaction at first hospital visit. After initial treatment, only one of 18 children achieved symptomatic and histologic remission and had a long-term treatment plan. CONCLUSIONS: The calculated incidence among children was lower compared to similar studies. Combined with poor remission rates and lack of follow-up, it is likely that EoE is an underdiagnosed and insufficiently treated disease among children in NDR. Our findings suggest that more knowledge concerning EoE in children could lead to a higher incidence, shorter diagnostic delay and more effective treatment.

BACKGROUND: Foreign body impaction is a frequent indication of urgent endoscopy. One of the reasons for impaction is eosinophilic oesophagitis (EE). To analyze characteristics of oesophageal foreign body impactions and their relationship with eosinophilic oesophagitis. METHODS: In this retrospective study, urgent endoscopies in a tertiary care centre were analyzed. We included all urgent endoscopies due to bolus and foreign body impactions performed between September 1st 2018 and September 1st 2020. We reviewed clinical data of all patients who were diagnosed with EE and compared it to impactions that were due to other motives. The mean follow-up time was 18.7 months. RESULTS: 693 urgent endoscopy procedures were performed. 239 (34%) of these were due to foreign body ingestion. Mean age of the patients was 63 years old and 135 (63%) were men. EE was diagnosed in 36 (17%) patients. The factors associated with EE were age, to be younger than 50 years (OR, 7.3; 95% CI, 1.1-48.4; p=0.04), asthma/rhinitis/atopic dermatitis (OR, 8.9; 95% CI, 2.3-35.3; p=0.002), findings in the endoscopy as trachealization (OR, 9.7; 95% CI, 1.3-70.9; p=0.03) and psychotropic/calcium channel blocker drugs (OR, 0.09; 95% CI, 0.009-0.9; p=0.04). 15 (7%) patients died. In 6 of them death was impaction-related. None patients with EE died. CONCLUSIONS: Foreign body impaction in the upper gastrointestinal tract due to EE is a frequent cause of urgent endoscopy. Being under 50 years of age, having asthma/rhinitis/atopic dermatitis, trachealization on the oesophagus and not taking psychotropic/calcium channel blocker drugs are factors associated with the diagnosis of EE. Mortality in the follow-up of patients without EE is important.

OBJECTIVE: Acid exposure time (AET) from ambulatory pH studies and reflux oesophagitis are independent measurements used by the Lyon classification to diagnose GORD. This study aimed to validate AET reference ranges and diagnostic thresholds by analysis of 96-hour wireless pH studies from healthy, asymptomatic controls (HCs) and patients with and without oesophagitis. DESIGN: HC and consecutive patients referred for wireless pH studies (off acid suppressants for >7 days) underwent 96-hour pH studies at two tertiary referral centres. Erosive oesophagitis was categorised by the Los Angeles (LA) classification. Linear regression and receiver operating curve (ROC) analysis were performed to define optimal diagnostic cut-offs. RESULTS: Prolonged, 96-hour pH studies were completed in 39 HCs (age 28 (18-53) years, 72% female) and 944 patients (age 46 (16-85) years, 65% female), of whom 136 (14.5%) had reflux oesophagitis. Median AET in HC was 1.3% (upper 95th percentile 4.6%) for any study day and 2.6% (upper 95th percentile 6.9%) for the worst day (24-hour period) during the study. ROC analysis for average AET differentiated HC from patients with moderate-to-severe oesophagitis (LA BCD; sensitivity 87%, specificity 95%, positive predictive value (PPV) 59%, negative predictive value 99% for a cut-off AET of 4.3%; area under the receiver operating curve 0.95). Specificity was higher, but PPV was substantially lower for severe oesophagitis (LA CD). 'Worst-day' analysis provided similar results; however, day-to-day variability was high. CONCLUSION: Diagnostic thresholds for average AET were identified that accurately discriminate between HCs and patients with erosive oesophagitis. The findings provide conditional support for diagnostic criteria for GORD proposed by the Lyon Consensus.

Our understanding of inflammatory diseases of the gastrointestinal tract, including those of the oesophagus, has expanded in recent years. Once attributed almost exclusively to gastro-oesophageal reflux disease or infection, it is now recognised that oesophagitis may occur due to a variety of distinct disease entities. Many of these conditions cause debilitating and persistent symptoms, impacting upon quality of life and necessitating ongoing surveillance and treatment. This review will consider the clinical, endoscopic and histopathological features of these novel and rare forms of oesophagitis.

INTRODUCTION: Although oesophageal motor disorders (OMDs) are frequent in systemic sclerosis (SSc), the frequency of associated endoscopic lesions is unknown. We aimed at assessing the presence of endoscopic lesions in SSc patients with OMD. The secondary objective was to identify the clinical and serological profile of such patients. METHODS: This retrospective study included SSc patients suffering from OMD diagnosed by oesophageal high-resolution manometry (OHRM) and with recent upper gastro-intestinal endoscopy (UGIE). Clinical data collected were age, gender, body mass index, SSc disease duration, tobacco, SSc cutaneous type, non-digestive SSc visceral disorders, oesophageal symptoms, serological profile (autoantibodies), proton pump inhibitor use, time between SSc diagnosis and UGIE. RESULTS: 53 selected patients from 210 SSc patients investigated by OHRM in our department were included. Among these patients, 25 (47.2%) had endoscopic lesions: 18 (34.6%) had oesophagitis and 7 (13.5%) had Barrett's oesophagus. The only two parameters significantly associated with endoscopic lesions were a shorter disease duration (6 vs. 11 years; p = .002) and a shorter delay between SSc diagnosis and UGIE (3 vs. 8.5 years; p = .002). No other clinical or biological parameters could help identify the patients at risk of endoscopic lesion. CONCLUSION: In our study, only a shorter disease duration and a shorter delay between SSc diagnosis and UGIE were significantly associated with the presence of endoscopic lesions in patients with OMD, but no other parameters were identified. This study highlights the need to perform UGIE in SSc patients with OMD whatever their clinical symptoms.

Gastroesophageal reflux disease (GERD) is a common gastrointestinal disorder. In the present study, we investigated TRP vanilloid subfamily member 2 (TRPV2) expression in lower oesophageal sphincter (LES) and its involvement in acid reflux oesophagitis in rats. Expression of TRPV2 and nerve growth factor mRNAs was significantly enhanced in LES of rats with reflux oesophagitis compared with normal rats. TRPV2 was mainly expressed in inhibitory motor neurons, and partly in intrinsic and extrinsic primary afferent neurons, and macrophages in LES of normal and reflux oesophagitis rats. Number of TRPV2-immunopositive nerve fibres was significantly increased, but that of nNOS-, CGRP-, and PGP9.5-nerve fibres was not changed in reflux oesophagitis compared with normal group. Probenecid produced nitric oxide production and relaxation in LES and this response was significantly enhanced in oesophagitis compared with normal group. Probenecid-induced relaxant effect was blocked by a TRPV2 inhibitor, tranilast, and a NOS inhibitor, NG-nitro-l-arginine methyl ester, in reflux oesophagitis rats. Oral administration of tranilast significantly improved body weight loss, oesophageal lesions, and epithelial thickness in oesophagitis model. These results suggest that up-regulation of TRPV2 in inhibitory motor neurons is involved in LES relaxation in oesophagitis model. TRPV2 inhibition might be beneficial for treatment of GERD.

Eosinophilic oesophagitis is a relapsing inflammatory disorder involving oesophagus identified over 30 years ago. Diagnosis is made by upper gastrointestinal endoscopy and oesophageal biopsies. There is huge variation in management practices across the globe. Therapeutic options include the use of proton pump inhibitors, topical steroids, and elimination diet. Biologics and immunomodulator drugs are being explored but not yet recommended in children. Long-term treatment may be required to control symptoms and to prevent complications such as fibrosis/stricture.Conclusion: Even though clinicians have better understanding of eosinophilic oesophagitis, further research is warranted in exploring the unmet needs of developing a highly sensitive non-invasive biomarker for its diagnosis and response to treatment along with a robust and easily deliverable therapeutic option. What is Known: â¢Incidence of eosinophilic oesophagitis has increased over the recent years. â¢Diagnostic confirmation requires upper gastrointestinal endoscopy and therapeutic options include elimination diet and/or topical steroids. What is New: â¢There is a lack of consensus ion management strategy with wide variation across the globe. â¢There is a need to develop a highly reliable and non-invasive biomarker to diagnose eosinophilic oesophagitis and to monitor the response to treatment.

Dysphagia is a common problem affecting all ages. It is increasing in frequency particularly among the younger population due to the rising incidence of eosinophilic oesophagitis, a condition which often leads to acute presentation to hospital for the first time with food bolus obstruction requiring endoscopic removal. Careful history taking remains the first and most important step in evaluating dysphagia, and it is especially important to distinguish an oropharyngeal versus oesophageal origin, which helps to guide further investigation and therapy. The three main investigations for dysphagia remain endoscopy, barium study and manometry, with endoscopy also offering therapeutic potential. Management is largely determined by the eventual diagnosis, often in a multi-disciplinary setting.

AIM: Our aim was to evaluate upper GI pathology found endoscopically among children seen in a GI feeding clinic for persistent feeding problems compared with controls. METHODS: Esophagogastroduodenoscopy biopsy results were examined among two cohorts of children. The first group included 86 children evaluated in a gastroenterology feeding clinic for paediatric feeding disorders. A comparison was made with an age-matched control group of 86 children referred for endoscopy for conditions other than disordered feeding. RESULTS: In the feeding cohort, 57% had abnormal endoscopy biopsies. These included 30% with microscopic esophagitis and 15.1% with eosinophilic esophagitis (EoE). Among the controls, 53% had abnormal biopsies, which included 26% with microscopic esophagitis and 8% with eosinophilic esophagitis. The statistical comparison between groups included p = 0.98 for microscopic esophagitis and p = 0.15 for eosinophilic esophagitis. CONCLUSION: Results demonstrated similar prevalence of abnormal endoscopy biopsies and microscopic esophagitis in both groups. The incidence of eosinophilic esophagitis in the feeding group triples that of previous reports and nearly doubles controls. Our findings suggest paediatric feeding disorders which do not resolve may warrant investigation by upper endoscopy.

AIM: Eosinophilic oesophagitis (EoE) is a chronic inflammatory oesophageal disease, which has become more recognised in the past decade. We wanted to characterise our patients and review their course of disease and response to treatment. METHODS: We retrospectively reviewed the medical records of EoE patients from January 2010 to May 2018 in our Gastroenterology Institute. A hundred and two children were included in this study. We investigated the characteristics of patients and the response to three treatment options: proton pump inhibitors, elimination diet and topical steroids. The response to treatment was analysed according to 3 aspects: clinical, endoscopic appearance and histological features. RESULTS: Clinical improvement was noted in 55%, 75% and 87.5% on PPIs, diet and budesonide, respectively. Endoscopic improvement was noted in 38.4%, 51.4% and 65.4% on PPIs, diet and budesonide, respectively. Histological improvement was noted in 43.7%, 62.2% and 88.5% on PPIs, diet and budesonide, respectively. CONCLUSION: Our findings suggest that Israeli paediatric EoE patients have characteristics that resemble previous reports. Although there is a correlation between symptoms, endoscopic and histological appearance, we cannot rely on patients reports alone, and therefore, repeated endoscopy and biopsies are mandated. Topical steroids seem to be the most effective treatment option.
