Abstract
BACKGROUND Data on eosinophilic gastrointestinal disorders (EGIDs) are limited in the United Arab Emirates. OBJECTIVE This study aimed to describe the distribution of eosinophilic gastritis/gastroenteritis (EoG/EGE) and eosinophilic esophagitis (EoE) among patients whose data are recorded on the Cleveland Clinic Abu Dhabi (CCAD) systems. METHODS Anonymized aggregate data were obtained from the Clinerion Patient Network Explorer (PNEx®) network installed at the CCAD on patients diagnosed with EoG/EGE (n=17, of whom 11 (64.7%) were females) or with EoE (n=118, of whom 35 (29.7%) were females) between 2015 and 2022; 63 (53.4%) were diagnosed between 2020 and 2022. RESULTS The vast majority of EoE patients visited the gastroenterology clinic (111, 94.1%), followed by the primary care (70, 59.3%), the emergency medicine (60, 50.8%), and the immunology (59, 50%) units. A total of 84 patients with EoE also presented with another type-2 inflammatory condition including allergic rhinitis, food allergy, and atopic dermatitis. Proton pump inhibitors and corticosteroids were widely prescribed, and four patients with EoE have been commenced on biologics since 2020. However, heterogeneity of medication use was identified, warranting local clinical practice guidelines. CONCLUSION A referral network could be established with local and regional reach, which relies on a multidisciplinary approach for the management of EoE and associated type 2 co-morbidities. More studies are needed to better depict the clinical picture of patients with EGIDs in general and EoE, in particular, in terms of diagnosis, pharmacological treatment, non-medical interventions, disease course, and patient-reported outcomes.

The multidisciplinary approach to eosinophilia. Front Oncol 2023; 13:1193730.

Abstract
Eosinophilic granulocytes are normally present in low numbers in the bloodstream. Patients with an increased number of eosinophilic granulocytes in the differential count (eosinophilia) are common and can pose a clinical challenge because conditions with eosinophilia occur in all medical specialties. The diagnostic approach must be guided by a thorough medical history, supported by specific tests to guide individualized treatment. Neoplastic (primary) eosinophilia is identified by one of several unique acquired genetic causes. In contrast, reactive (secondary) eosinophilia is associated with a cytokine stimulus in a specific disease, while idiopathic eosinophilia is a diagnosis by exclusion. Rational treatment is disease-directed in secondary cases and has paved the way for targeted treatment against the driver in primary eosinophilia, whereas idiopathic cases are treated as needed by principles in eosinophilia originating from clonal drivers. The vast majority of patients are diagnosed with secondary eosinophilia and are managed by the relevant specialty-e.g., rheumatology, allergy, dermatology, gastroenterology, pulmonary medicine, hematology, or infectious disease. The overlap in symptoms and the risk of irreversible organ involvement in eosinophilia, irrespective of the cause, warrants that patients without a diagnostic clarification or who do not respond to adequate treatment should be referred to a multidisciplinary function anchored in a hematology department for evaluation. This review presents the pathophysiology, manifestations, differential diagnosis, diagnostic workup, and management of (adult) patients with eosinophilia. The purpose is to place eosinophilia in a clinical context, and therefore justify and inspire the establishment of a multidisciplinary team of experts from diagnostic and clinical specialties at the regional level to support the second opinion. The target patient population requires highly specialized laboratory analysis and therapy and occasionally has severe eosinophil-induced organ dysfunction. An added value of a centralized, clinical function is to serve as a platform for education and research to further improve the management of patients with eosinophilia. Primary and idiopathic eosinophilia are key topics in the review, which also address current research and discusses outstanding issues in the field.

Abstract
Background: Diagnosis and management of eosinophilic esophagitis (EoE) occur via esophagogastroduodenoscopy with tissue biopsy. Objective: We sought to determine if salivary microribonucleic acid (miRNA) levels could differentiate children with EoE, serving as a noninvasive biomarker. Methods: Saliva was collected from children undergoing esophagogastroduodenoscopy (N = 291). miRNA analysis was conducted on 150 samples: EoE (n = 50), no pathologic alteration (n = 100). RNA was quantified with high throughput sequencing and aligned to build hg38 of the human genome using sequencing and alignment software. Quantile normalized levels of robustly expressed miRNAs (raw counts > 10 in 10% of samples) were compared across EoE and non-EoE groups with Wilcoxon rank sum testing. miRNA biomarker candidates were selected based on variable importance projection (VIP) scoring with partial least squared discriminant analysis (VIP > 1.5). Ability of these miRNAs to differentiate EoE status was assessed via logistic regression. Putative biologic targets for the miRNA candidates were determined in miRNA pathway analysis software. Results: Of the 56 salivary miRNAs reliably detected, miR-205-5p displayed the largest difference between EoE and non-EoE groups (V = 1623, adjusted p = 0.029). Six miRNAs (miR-26b-5p, miR-27b-3p, Let-7i-5p, miR-142-5p, miR-30a-5p, miR-205-5p) displayed elevated VIP scores (>1.5) and were able to differentiate EoE samples on logistic regression analysis with 70% sensitivity and 68% specificity. These six miRNAs demonstrated significant enrichment for gene targets involved in valine, leucine, and isoleucine biosynthesis (p = 0.0012), 2-oxycarboxylic acid metabolism (p = 0.043), and steroid hormone biosynthesis (p = 0.048). Conclusions: Salivary miRNAs represent a noninvasive, biologically relevant measure that may aid disease monitoring of EoE.
