Eosinophilic Esophagitis (eosinophilic + esophagitis)
Selected AbstractsRedefining the role of lymphocytes in gastroesophageal reflux disease and eosinophilic esophagitisDISEASES OF THE ESOPHAGUS, Issue 5 2010B. Basseri SUMMARY Eosinophilic esophagitis (EoE) and reflux esophagitis (RE) overlap clinically and histologically. RE is characterized by epithelial infiltration with small numbers of neutrophils and eosinophils, EoE by a prominent eosinophilic infiltrate. Lymphocytic esophagitis (LE), a new entity characterized by peripapillary lymphocytosis, questions the role lymphocytes play in esophageal inflammation. We test the hypothesis that lymphocyte infiltration in RE differs from EoE. One blinded pathologist read esophageal biopsies from 39 RE and 39 EoE patients. Both groups demonstrated significant numbers of lymphocytes (RE 22.7 ± 2.2/HPF, EoE 19.8 ± 1.8/HPF). Eosinophils/HPF in RE and EoE were 2.8 ± 0.7 and 74.9 ± 8.2, respectively (P < 0.001). Neutrophils were uncommon in RE (0.26 ± 0.16/HPF) and EoE (0.09 ± 0.04; P = 0.07). Eight of the 39 RE specimens had ,50 lymphocytes in ,1 HPF. Two were consistent with LE. There was an inverse correlation between numbers of eosinophils and lymphocytes in EoE (R = ,0.47; P = 0.002), and no correlation between them in RE (R = 0.18; P = 0.36). The patients with EoE who used antireflux medications had fewer lymphocytes (16.3 ± 1.3 vs 22.2 ± 2.3/HPF; P = 0.030) and eosinophils (55.6 ± 5.2 vs 76.0 ± 8.7/HPF; P = 0.042) than those who did not. The pathological role of lymphocytes in RE and EoE may be underestimated. Our observation that 5% of the RE specimens meet histopathological criteria for LE potentially blurs the line between these entities. The observation that eosinophil counts are lower in EoE when antireflux meds are used supports the notion that reflux plays a role in the clinical expression of EoE. [source] Eosinophilic esophagitis: an updateDISEASES OF THE ESOPHAGUS, Issue 1 2007D. D. Ferguson SUMMARY., Eosinophilic esophagitis (EE) is a disease that is being recognized with increasing frequency. In children it is responsible for feeding disorders, vomiting, reflux symptoms and abdominal pain and in adults it causes dysphagia and esophageal food impactions. The diagnosis requires the histologic finding of > 20 eosinophils per high powered field in esophageal squamous mucosa. The most common treatment regimens in children and adults involve the ingestion of topical corticosteroids. Symptomatic relapse after one treatment course is common, and many patients require repeated courses of treatment. The long-term prognosis of EE is largely unknown.

[source] Diagnosis of eosinophilic esophagitis after fundoplication for ,refractory reflux': implications for preoperative evaluationDISEASES OF THE ESOPHAGUS, Issue 3 2010Evan S. Dellon SUMMARY A small percentage of patients who carry the diagnosis of refractory gastroesophageal reflux disease (GERD) actually have eosinophilic esophagitis (EoE). The purpose of this study was to describe a series of patients who underwent fundoplication for presumed refractory GERD, but subsequently were found to have EoE. We performed a retrospective analysis of our EoE database. Patients diagnosed with EoE after Nissen were identified. Cases were defined according to recent consensus guidelines. Five patients underwent anti-reflux surgery for refractory GERD, but were subsequently diagnosed with EoE. None had esophageal biopsies prior to surgery, and in all subjects, symptoms persisted afterward, with no evidence of wrap failure. The diagnosis of EoE was typically delayed (range: 3,14 years), and when made, there were high levels of esophageal eosinophilia (range: 30,170 eos/hpf). A proportion of patients undergoing fundoplication for incomplete resolution of GERD symptoms will be undiagnosed cases of EoE. Given the rising prevalence of EoE, we recommend obtaining proximal and distal esophageal biopsies in such patients prior to performing anti-reflux surgery. [source] Resolution of remodeling in eosinophilic esophagitis correlates with epithelial response to topical corticosteroidsALLERGY, Issue 1 2010S. S. Aceves Abstract Background:, Esophageal remodeling occurs in eosinophilic esophagitis (EE) patients but whether the components of remodeling in the subepithelium are reversible by administration of topical oral corticosteroids is unknown. Methods:, We quantitated the degree of lamina propria remodeling in esophageal biopsies obtained before and after at least 3 months of therapy with budesonide in 16 pediatric EE subjects. In addition, we investigated whether corticosteroid therapy modulated vascular activation (expression of VCAM-1; level of interstitial edema), TGF,1 activation (levels of TGF,1, phosphorylated Smad2/3), and performed a pilot analysis of a polymorphism in the TGF,1 promoter in relation to EE subjects who had reduced remodeling with budesonide therapy. Results:, EE subjects were stratified based on the presence (n = 9) or absence (n = 7) of decreased epithelial eosinophilia following budesonide. Patients with residual eosinophil counts of ,7 eosinophils per high power field in the epithelial space (responders) demonstrated significantly reduced esophageal remodeling with decreased fibrosis, TGF,1 and pSmad2/3 positive cells, and decreased vascular activation in association with budesonide therapy. Responders were more likely to have a CC genotype at the ,509 position in the TGF,1 promoter. Conclusions:, Reductions in epithelial eosinophils following budesonide therapy were associated with significantly reduced esophageal remodeling. [source] Multifactorial dysphagia: Diffuse idiopathic skeletal hyperostosis and eosinophilic esophagitis,THE LARYNGOSCOPE, Issue 1 2010Grace Nimmons MD Abstract Swallowing is a complex, multistage event with oral, pharyngeal, and esophageal phases. A thorough clinical examination for swallowing complaints begins to differentiate whether the problem is due to anatomic, mechanical, or neurologic etiologies. Based on the clinical suspicion, additional tests may be beneficial, including fluoroscopic and direct imaging methods, and electrophysiologic measurements. A multidisciplinary approach may also be advantageous, as in this case of dysphagia from diffuse idiopathic skeletal hyperostosis and eosinophilic esophagitis, which incorporated care from otolaryngology, speech pathology, orthopedic surgery, and gastroenterology.
