Project description:BackgroundBenralizumab is a monoclonal antibody targeting the IL-5 receptor used in the treatment of asthma. The use of benralizumab in other conditions is only emerging and could represent a therapeutic option for other eosinophil-associated diseases. Here, we report the case of a patient suffering from eosinophilic esophagitis and asthma who achieved histological remission of eosinophilic esophagitis (EoE) under benralizumab treatment for his asthma.Case summaryOur patient was a 56-year-old white male with a history of eosinophilic esophagitis and severe asthma. After years of usual treatments, including topical steroids, biological treatment with mepolizumab, and standard asthma treatment, only poor control of both conditions was obtained. A control gastroscopy after the initiation of benralizumab showed complete histological remission of his EoE.ConclusionOur case shows the effects of therapy with a novel agent not yet approved for this condition but for other diseases, with histological resolution of EoE after treatment. Complete clinical remission was not observed, which exemplifies the complex nature of EoE, its associated psychosomatic burden, and the chronification of the disease. Nevertheless, monoclonal antibodies targeting the Th2 response and, in our case, an IL5 receptor antagonist, achieved complete histological remission, which was not the case with an antibody against IL-5, which was also initiated to treat asthma.

Project description:BackgroundEvaluation of IgE-mediated food sensitivity is frequently performed for patients with eosinophilic esophagitis (EoE). However, the clinical relevance of identifying IgE-mediated sensitivity to foods in adults is unclear.ObjectiveTo determine whether EoE associated with food or aeroallergen sensitivity represents a phenotype of EoE with distinct clinical or biological features.MethodsA medical record review identified 257 patients with a diagnosis of EoE evaluated in the adult allergy clinic at the University of Wisconsin Hospital and Clinics from 2008 to 2013. Patient records were reviewed to capture measures of disease severity, endoscopy results, pathology reports, allergy testing, medical management and patient-reported outcomes.ResultsEvaluation of food sensitization with skin prick testing and/or serum IgE was performed for 93% of patients. Sensitization to at least 1 food was identified in 54% of patients who were more likely to report concomitant asthma, allergic rhinitis, eczema, and/or food allergy compared with nonfood sensitive patients. Aeroallergen sensitivity was identified in 87% of patients tested. Clinical characteristics, including EoE symptoms, disease severity, endoscopic findings, peripheral eosinophilia, and patient-reported outcomes, did not differ between food sensitive and non-food sensitive patients. However, on endoscopy, aeroallergen sensitive patients were more likely to have strictures and less likely to exhibit felinization compared with non-aeroallergen sensitized patients.ConclusionAdults with EoE and IgE-mediated food sensitivity are not phenotypically different than non-food sensitive patients. There is no clear clinical utility in identifying food sensitivity in adults with EoE. Further studies are needed to determine whether aeroallergen sensitivity represents a distinct phenotype of EoE.

Project description:Elemental diets, dietary elimination, and steroid therapies are the most common therapies in the clinical trials for eosinophilic esophagitis (EoE). Histological findings (usually reported as eosinophils per microscopic high-powered field [hpf]) remain the most common end-point used to define response. Yet, the threshold for defining "response" and "remission" are ill-defined among consensus guidelines and may vary from study to study. We conducted a systematic literature review of articles on eosinophilic esophagitis, published between January 2007 and November 2017, considering histological remission as the primary outcome. We abstracted treatment information and definitions of histological remission or response. A comparison of definitions of histological remission across and within institutions was performed. A total of 61 articles were included in this review, with approximately 60% of the studies published from centers in the United States. Histological definitions of remission of EoE ranged from 0 to ≤20 eosinophils/hpf. The most stringent criteria, ranging from 0 to ≤5 eosinophils/hpf, were commonly used in interventional trial studies that examined the effects of new treatments. We found remarkable variability in definitions between studies, treatment types, and regions. Age or epidemiological distribution of study subjects did not influence the criteria for histological remission. Clinical and histological improvements are important measures of the effects of treatment. Histological findings, the most objective measure of treatment, should provide an optimal method for comparing the effectiveness of various treatments. Yet, our findings suggest a lack of consistent remission criteria in published studies. Considering these inconsistencies, it is difficult to compare the effectiveness of various treatments.

Project description:IntroductionPneumatosis cystoides intestinalis is a rare disease characterized by presence of multilocular cysts in the gastrointestinal wall. Rarely, patients may experience symptoms secondary to the cysts. The pathogenesis of pneumatosis cystoides intestinalis is still unclear and many theories have been advocated to explain the exact origin. Complications occur in about 3% of cases and include obstruction, intussusception, volvulus, haemorrhage and intestinal perforation.Case presentationThe author reported a male patient aged 56 years presented to the emergency department with acute upper abdominal pain. Widespread variable sized serosal intestinal air cysts were seen at the first look involving long segment of jejunum and ileum. Perforated duodenal ulcer, as the cause of generalized peritonitis, was repaired with direct closure and omental patch. A second laparotomy, was done and exploration was systematically performed and denoted hugely distended stomach with cicatrisation at the site of previous closure of perforated duodenal ulcer and the whole length of small gut was completely free from the already described pneumatosis cystoides intestinalis.ConclusionThe pneumatosis cystoides intestinalis is a rare disease and suspicion of this disease process should be based on imaging and clinical finding. The therapy can be conservative or surgical in restricted situations.

Project description:Eosinophilic esophagitis (EoE) is a recently recognized inflammatory disorder driven by food hypersensitivity; however, the specific foods and mechanisms involved are unclear. In patients with EoE, we have found that hypersensitivities to corn and peanuts are the most common. Accordingly, we sensitized and exposed mice either intranasally or intragastrically with corn or peanut extract or saline. Esophageal eosinophilia, the genes of eosinophil-directed cytokines, and allergen-induced antibodies were examined in mice challenged with corn or peanut extract or saline. A high number of esophageal lamina propria eosinophils as well as eosinophilic microabscesses, intraepithelial eosinophils, extracellular eosinophilic granules, thickened and disrupted epithelial mucosa, and mast cell hyperplasia were observed in the esophagus of peanut or corn allergen-challenged mice. Mechanistic analysis indicated that para-esophageal lymph nodes might be critical in the trafficking of eosinophils to the esophagus and in EoE association to airway eosinophilia. Furthermore, experimentation with gene-targeted mice revealed that peanut allergen-induced EoE was dependent on eotaxin and invariant natural killer T (iNKT) cells, as CD1d and eotaxin-1/2 gene-deficient mice were protected from disease induction. Thus we provide evidence that para-esophageal lymph nodes are involved in food- or aeroallergen-induced eosinophilia and patchy EoE pathogenesis, likely a mechanism dependent on eotaxins and iNKT cells.

Project description:Patients with Eosinophilic esophagitis (EoE) require long-lasting resolution of inflammation to prevent fibrostenosis and dysphagia. However, the dissociation between symptoms and histologic improvement suggests persistent molecular drivers despite remission. We aimed to characterize persisting molecular alterations in pediatric patients with EoE using tissue proteomics. Esophageal tissue biopsies (n=151) and clinical data were collected prospectively from pediatric patients with EoE (N=34), gastroesophageal reflux disease (GERD; N=10; inflammatory controls) or functional disorders (FD; N=20; non-inflammatory controls). Biospies (n=131) acquired from the diagnostic endoscopy and up to 7 follow-ups were considered for proteome analysis in patients with EoE, while for GERD and FD only biopsies from initial diagnosis were included. Histologically active EoE (15 eosinophils per high power field (hpf)) was diagnosed in 79 biopsies and 52 samples derived from patients with EoE in remission (15 eosinophils per hpf). After microdissection of the epithelium proteins were extracted from the esophageal tissue followed by a liquid chromatography-tandem mass spectrometry. Proteomic analysis identified 3,704 different proteins in total across all samples.

Project description:ObjectiveTo review the understanding of the pathogenesis of eosinophilic esophagitis (EoE) and the role of the immune system in the disease process.Data sourcesPeer-reviewed articles on EoE from PubMed searching for "Eosinophilic Esophagitis and fibrosis" in the period of 1995 to 2013.Study selectionsStudies on the clinical and immunologic features, pathogenesis, and management of EoE.ResultsRecent work has revealed that thymic stromal lymphopoietin and basophil have an increased role in the pathogenesis of disease. Additional understanding on the role of fibrosis in EoE is emerging.ConclusionThe incidence of EoE is increasing like most atopic disease. Similar to other allergic diseases, EoE is treated with topical steroids and/or allergen avoidance.

Project description:ObjectivesEosinophilic esophagitis (EoE) is characterized by remissions and relapses. Guidelines defining remission do not exist and therefore remission is inconsistently identified. We sought to define histology remission in EoE.MethodsEsophageal biopsies, obtained at the time the validated pediatric EoE symptoms scores v2.0 (PEESS v2.0) questionnaire was completed (N = 42), were scored using the validated EoE Histology Scoring System. An EoE Histology Remission Score (EoEHRS) was constructed and specified that in all esophageal sites sampled the peak eosinophil count was <15 per high power field (HPF); in addition, neither the total grade (severity of pathology) nor stage (extent of pathology) scores could exceed 3 (possible total maximum score for each was 24). Spearman correlation coefficients were generated for histology/symptom correlations; coefficient range 0.31 to 0.50 was considered moderate.ResultsEoE Histology Scoring System composite and individual feature scores from proximal and distal esophageal biopsies correlated moderately with PEESS v2.0 mean scores (0.48-0.36, P < 0.01), and with scores in the dysphagia (0.39-0.30, P ≤ 0.01), pain (0.48-0.34, P ≤ 0.01), and gastroesophageal reflux disease (0.51-0.32, P ≤ 0.01) domains. Biopsies that met full EoEHRS criteria had reduced biomarkers, specifically expression of the mast cell markers CPA3 and tryptase mRNA, and reduced eosinophil peroxidase deposition (P < 0.03), compared to those with nonremission scores. Subjects whose biopsies met EoEHRS remission criteria reported reduced symptoms for all domains except nausea and vomiting (P ≤ 0.01).ConclusionsThe EoEHRS correlated with reduced biomarkers of disease activity and reduced symptoms, and therefore may be useful to inform clinical care and interstudy comparisons.
