ABSTRACT Eosinophilic esophagitis (EE) is an emerging disease. Its incidence and prevalence have been exponentially increasing in the last decade. The clinical manifestations of EE vary especially in children. Allergic reaction is strongly implicated in the disease. The aim of the present study was to retrospectively examine the demographic, clinical, laboratory, and endoscopic features of pediatric patients with EE, in order to better understand the diversity of the disease, thereby improving clinical diagnosis and treatment.
The data were retrospectively collected from 20 pediatric patients with biopsy-proven EE. Demographic information, clinical symptoms and duration, as well as endoscopic findings were correlated and statistically analyzed.
Median age at diagnosis was 11 years. Male patients had higher prevalence of EE. Thirty-five percent of the children had food allergy on either skin prick test or IgE radioallergosorbent test, and atopic diseases were common in the group. Gastroesophageal reflux appeared to be the major symptom in younger children, whereas dysphagia and food impaction were more common in older patients. The referral and final diagnosis were often delayed. Esophageal white exudates were the most prominent feature in the younger age group, whereas esophageal ring-like lesion occurred more often in older children.
EE is more common in male subjects. The clinical and endoscopic features depend upon the age. Allergic processes are strongly involved in pathogenesis. The present results will improve understanding of the characteristics of the disease in the pediatric population and enhance clinicians' vigilance for the diagnosis of EE.

    ABSTRACT: Eosinophilic esophagitis (EoE) has become a common gastrointestinal disease. It is characterized by severe eosinophil infiltration in the esophagus. EoE is strongly associated with food allergy, asthma, atopic dermatitis, and other allergic diseases. T lymphocytes, especially Th2 cells, play an instrumental role in the development of allergic inflammation. Recent studies have shown that the ligation of co-stimulatory molecules contributes to the activation, differentiation, and proliferation of T cells. In this review, we will discuss the growing evidence of co-stimulatory molecules including OX40, Light, and HVEM in the pathogenesis of Th2-driven EoE. Our goal is to provide the rationale for the development of novel therapy therapies that target co-stimulatory molecules.

    ABSTRACT: Dysphagia is a common problem that has the potential to result in severe complications such as malnutrition and aspiration pneumonia. Based on the complexity of swallowing, there may be many different causes. This article presents a systematic literature review to assess different comorbid disease associations with dysphagia based on age. The causes of dysphagia are different depending on age, affecting between 1.7% and 11.3% of the general population. Dysphagia can be a symptom representing disorders pertinent to any specialty of medicine. This review can be used to aid in the diagnosis of patients presenting with the complaint of dysphagia.

    ABSTRACT: Eosinophilic esophagitis and herpes simplex esophagitis are separately well-described entities, but their simultaneous occurrence may pose a special challenge to the clinician, especially regarding the optimal therapeutic approach. The following case report describes a patient with a history of cow's milk and dairy products intolerance, but without an underlying immunologic defect, in whom eosinophilic esophagitis was diagnosed in the course of primary herpes simplex virus 1 (HSV1) infection that clinically presented as herpes labialis and severe esophagitis. The diagnosis was confirmed by a polymerase chain reaction from cytological brush and by immunohistochemical staining that detected the presence of HSV1 DNA in esophageal mucosa, and histologically by persistent eosinophil-predominant inflammation, typical of eosinophilic esophagitis. Despite severe clinical presentation, the HSV1 infection was self-limited. After a directed elimination diet was introduced, the clinical course was favorable, without the need for antiviral therapy.
