Abstract   Pathological identification of esophageal eosinophilia (EE) is considered to be most important and critical step for diagnosis of eosinophilic esophagitis (EoE). Although several endoscopic findings related with EoE have been reported, it is still difficult to exclude other causes of EE, such as gastroesophageal reflux disease. Here, we noted a novel endoscopic finding related with EoE termed ‘Caterpillar sign’. The aim of this study was to evaluate its clinical significance for the diagnosis of EoE. Methods One hundred and seventy-four patients who were endoscopically suspected with EoE at our hospital and affiliated institutions were enrolled. EoE was defined clinically by symptoms of esophageal dysfunction and histologically by the presence of EE [≧15 eosinophils/high power field (HPF)]. Endoscopic findings at baseline were retrospectively reviewed. ‘Caterpillar sign’ was defined as a stair-like, fragile, slight mucosal protruded lesion sandwiched between longitudinal furrows, such as the Caterpillar traces remaining on the ground (Figure). Furthermore, the clinicopathological features of patients having ‘Caterpillar sign’ were evaluated. Results One hundred and seventy-four patients (92 males, 82 females with mean age of 49.7) suspected with EoE were evaluated, of whom 60 (34.5%) was finally diagnosed as EoE. ‘Caterpillar sign’ was found in 48 patients (80.0%). Sensitivity and Specificity of ‘Caterpillar sign’ for the diagnosis of EoE was 0.80 (95% confidence interval [CI] 0.72–0.85) and 0.94 (95% CI 0.90–0.97), respectively. Furthermore, the presence of ‘Caterpillar sign’ was associated with degree of eosinophil infiltration (Caterpillar sign positive: 42.9 ± 49.3/HPF vs. Caterpillar sign negative: 6.7 ± 24.4/HPF, p < 0.0001). Conclusion This novel finding termed ‘Caterpillar sign’ was clinically useful for the definitive diagnosis of EoE and associated with degree of eosinophil infiltration.

Histologic Diagnosis

AbstrakEosinofilik esofagitis merupakan gangguan dimana terjadi infiltrasi eosinofil pada mukosa superfisial esophagus yang berhubungan dengan alergi makanan dan kondisi atopi seperti asma, dermatitis atopi, rhinitis alergika dan sering bersamaan dengan Gastroesophageal Reflux Disease (GERD). Diperkirakan insiden tahunan 43 per 10.000 pada anak. Gejala klinis mirip dengan GERD yaitu muntah, regurgitasi, nausea, nyeri dada atau epigastrium, disfagia dan hematemesis. Sekitar 50% pasien memiliki gejala alergi dan lebih 50% pasien memiliki orang tua dengan riwayat alergi. Diagnosis dapat ditegakkan berdasarkan pemeriksaan endoskopi dan histologis. Gambaran endoskopi yang ditemukan antara lain feline esophagus, corrugated esophagus, ringed esophagus, atau concentric mucosal rings, eksudat putih, vesikel atau papul dan hilangnya pola vaskular menunjukkan area fokus infiltrasi eosinofil. Diagnosis secara histologis sangat penting dimana kriteria eosinofilik esofagitis adalah jika ditemukan eosinofil >20/HPF (High Power Field). Terapi yang diberikan adalah terapi diet, farmakologis seperti kortikosteroid sistemik atau topikal, penghambat reseptor leukotrin dan anti IL-5.Kata kunci: eosinofilik esofagitis, alergi makanan, atopiAbstractEosinophilic esophagitis is a disorder which there is eosinophil infiltration on superficial esophageal mucosa. It’s correlated with food allergy and atopy condition such as asthma, atopy dermatitis, rhinitis allergic and often in conjunction with Gastroesophageal Reflux Disease ( GERD). The incidence approximately 43/10.000 in children. The symptoms are similar with GERD, which one vomit, regurgitation, nausea, chest or epigastrium pain, dysphagia and hematemesis. About 50% patient has allergic symptoms and more than 50% parent of the patient has allergic history. The diagnose can be made base on endoscopic and histological examination. Endoscopic examination shows feline esophagus, corrugated esophagus or concentric mucosal rings, white exudates, vesikel or papul and diminished of vascular pattern, showing eosinophyl infiltration focus area. Histologic diagnosis is very important where the criteria for eosinophilic esophagitis is found eosinophils > 20 / HPF (High Power Field) within the superficial esophageal mucosa. Therapy eosinophilic esophagitis are diet therapy, pharmacological therapy with systemic or topical corticosteroid, leucotriene receptor antagonist and anti IL-5.Keywords:Eosinophilic esophagitis, food allergy, atopy

Abstract Background and study aims Characteristic endoscopic findings, such as linear furrows, rings, and whitish exudates, indicate the presence of esophageal eosinophilia (EE), though no specific findings are known to distinguish eosinophilic esophagitis (EoE) from proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE). Here, we present a novel endoscopic finding in some EE patients possessing a linear longitudinal arrangement of whitish nodules with the appearance of the back of an Ankylosaurus dinosaur, termed Ankylosaurus back sign (ABS), and evaluations of its significance in affected patients. Patients and methods Fifty-five patients diagnosed with EE (≥ 15 eosinophils/high power field) who were treated at our hospital and shown to evaluate a PPI response were enrolled. Endoscopic findings at baseline and clinical parameters were retrospectively reviewed. Furthermore, the clinicopathological features of patients with ABS, as well as the relationship between its presence and PPI response were evaluated. Results Fifty-five patients (47 males, 8 females) with EE (17 with EoE, 38 with PPI-REE) were evaluated, of whom 50 (90.9 %) had linear furrows, the most frequently found feature, while ABS was found in 9 (16.4 %). Inter-observer agreement was substantial for ABS (κ 0.77). Interestingly, all patients with ABS had PPI-REE. Our findings revealed that the presence of ABS was closely associated with reflux esophagitis (RE) in patients with PPI-REE. Conclusions Although ABS was less frequent than typical endoscopic findings such as linear furrows in EE, this novel finding was closely associated with PPI-REE accompanied with RE. The clinical implications of ABS in patients with EE should be investigated further.

Abstract Background and study aims Eosinophilic esophagitis (EoE) is a chronic immune disease with increasing incidence. It is clinically defined by symptoms of esophageal dysfunction and histologically by eosinophilic polynuclear cell infiltration of the esophageal mucosa. Symptoms are not specific and include gastroesophageal reflux disease (GERD), dysphagia, vomiting or dietary blockages. Chronic inflammation of the mucosa may lead to narrowing of the esophageal lumen responsible for impactions. Extraction procedures can be complicated by dissection and perforation. Rare spontaneous ruptures of the esophagus known as Boerhaave syndrome are also possible. We report five cases of esophageal perforation in children with EoE, three with spontaneous rupture and two after an endoscopic procedure. The evolution was favorable under medical treatment.

Abstract Context.—Although the healthy esophageal mucosa contains no eosinophils, eosinophilic infiltration is observed in 2 major clinicopathologic settings: gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EE). The prevalence of EE is increasing in many countries, and this increase seems only partly to be due to a better awareness of the pathology, following the relatively recent description of EE. Gastroesophageal reflux disease and EE represent 2 entities that do not respond to the same treatment modalities and, thus, need to be distinguished. However, diagnostic criteria of EE have been defined arbitrarily, and the more recent articles tend to prove that the overlap with GERD is probably greater than initially believed, leading the authors to advise strict exclusion of GERD before considering the diagnosis of EE. Objectives.—To provide pathologists with the currently proposed histologic criteria of GERD and EE, to stress the need to combine these criteria with clinical data and endoscopic findings, and to outline the remaining controversies. Data Sources.—This review is based on selected articles identified by a PubMed (US National Library of Medicine, Bethesda, Maryland) search of the literature in English for GERD and EE, a recent review by the American Gastroenterological Association (Bethesda), the Proceedings of the First International Gastrointestinal Eosinophil Research Symposium, and the authors' experience. Conclusions.—Proper identification of the etiology of eosinophilic infiltration of the esophagus allows accurate medical or surgical treatment and follow-up. Eosinophilic esophagitis and GERD diagnoses require integration of the histologic findings with the clinical and endoscopic data.

Abstract   Eosinophilic esophagitis (EoE) is an allergy-associated clinicopathologic condition gaining an increasing amount of recognition in various areas of the world. While the clinical definition and characteristics may differ depending on country and region, sufficient studies have not yet been performed in Japan. To assess the prevalence of EoE among the Japanese population and the clinical features and the prognosis associated with the disease. Methods Medical data from January 2012 to October 2018 was gathered from nine Japanese clinical institutes. EoE, defined as more than 15 intraepithelial eosinophils per high power field, was determined based on esophageal biopsies. Clinical and endoscopic patterns in the cases with EoE were investigated and compared with 186 age- and sex-matched controls. We also analyzed the treatment and prognosis of an individual patient. Results From 130,013 upper endoscopic examinations, 66 cases of EoE were identified (0.051%; mean age: 45.2 years (range 7-79); 45 males). Patients with EoE had more symptoms (69.7 vs. 10.8%; P < 0.01) such as dysphagia and food impaction, and more allergies (63.6 vs. 23.7%; P < 0.01) compared with the controls. The prevalence of atrophic gastritis was lower in EoE patients than in the controls (20.0% vs. 33.3%). In 55 patients analyzed, 32 patients (78.0%) received proton pump inhibitors with or without swallowed topical corticosteroids. During the follw-up period (mean 23 months), no patient got worse regarding clinical and endoscopic findings. Conclusion The prevalence of EoE in the Japanese population was 0.051% which was comparable with previous reports in Japan. Male predominance, a history of allergies, and the absence of Helicobacter pylori infection might be risk factors for EoE. Our study also indicated that the prognosis of EoE might be relatively good in Japanese populations.

Abstract Background and study aims Endoscopic findings of esophageal eosinophilia sometimes localize to small areas of the esophagus. A previous study suggested that pathogenesis of localized-type eosinophilic esophagitis (LEoE) was associated with acid reflux. However, LEoE treatment outcomes have not been studied. We aimed to analyze the clinical and histologic significance of LEoE in comparison with diffuse-type eosinophilic esophagitis (DEoE). Patients and methods This study included 106 patients with esophageal eosinophilia. Esophageal eosinophilia was defined as a condition where the maximum number of intraepithelial eosinophils was ≥ 15 per high-power field. LEoE was defined as an endoscopic lesion confined to one-third of the esophagus: upper, middle, or lower. Esophageal eosinophilia encompassing more than two-thirds of the esophagus was defined as DEoE. We retrospectively compared LEoE and DEoE in terms of clinical characteristics, histologic findings, and proportion of proton pump inhibitor (PPI) responders. Results Of 106 patients, 12 were classified as having LEoE and 94 were classified as having DEoE. The proportion of asymptomatic patients was significantly higher in the LEoE group than the DEoE group (42 % vs 7 %, P < 0.01). In the LEoE group, 10 patients (84 %) had endoscopic lesions in the lower esophagus. The maximum number of eosinophils did not differ between the groups (54 [24 – 71] for LEoE, 40 [20 – 75] for DEoE, P = 0.65). The prevalence of PPI responders was significantly higher in the LEoE group than the DEoE group (100 % vs 63 %, P = 0.01). Conclusion LEoE can be a sign of good responsiveness to PPI therapy.
