Allergic Comorbidity in Eosinophilic Esophagitis: Mechanistic Relevance and Clinical Implications
AbstractAllergic eosinophilic esophagitis (EoE) is a chronic, allergen-mediated inflammatory disease of the esophagus, and the most common cause of prolonged dysphagia in children and young adults in the developed world. While initially undistinguished from gastroesophageal reflux disease-associated esophageal eosinophilia, EoE is now recognized as a clinically distinct entity that shares fundamental inflammatory features of other allergic conditions and is similarly increasing in incidence and prevalence. The clinical and epidemiologic associations between EoE and other allergic manifestations are well established. In add...

Comprehensive Analysis of Serum and Fecal Bile Acid Profiles and Interaction with Gut Microbiota in Primary Biliary Cholangitis
AbstractAccumulation of bile acids (BAs) contributes significantly to the pathogenesis of primary biliary cholangitis (PBC). Here, we sought to systematically characterize the serum and fecal BA profiles and the linkage between BAs and gut microbiota in PBC. The serum and fecal BAs were compared between 65 UDCA treatment-naive PBC and 109 healthy controls using UPLC-MS in cross-sectional study. In a prospective study, a subgroup of patients was enrolled for BA and microbiota analysis before and after UDCA therapy. BA compositions in serum and feces significantly differed between treatment-naive PBC and controls. Particular...

The Effects of Air Pollution on the Development of Atopic Disease
AbstractAir pollution is defined as the presence of noxious substances in the air at levels that impose a health hazard. Thus, there has been long-standing interest in the possible role of indoor and outdoor air pollutants on the development of respiratory disease. In this regard, asthma has been of particular interest but many studies have also been conducted to explore the relationship between air pollution, allergic rhinitis, and atopic dermatitis. Traffic-related air pollutants or TRAP refers to a broad group of pollutants including elemental carbon, black soot, nitrogen dioxide (NO2), nitric oxide (NO), sulfur dioxide...

Food Protein-Induced Enterocolitis Syndrome: a Comprehensive Review
AbstractFood protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy that has been well-characterized clinically, yet it is still poorly understood. Acute FPIES is characterized by vomiting 1 –4 h and/or diarrhea within 24 h after ingestion of a culprit food. Chronic FPIES is the result of chronic exposure to an offending food that can result in chronic watery diarrhea, intermittent vomiting, and failure to thrive. FPIES typically presents in infancy and self-resolves by school age i n most patients. Adult-onset FPIES is rare, but it has been reported. Cow’s milk and soy are the most common ...

A Review of the Contribution of Mast Cells in Wound Healing: Involved Molecular and Cellular Mechanisms
AbstractMast cells (MCs), apart from their classic role in allergy, contribute to a number of biologic processes including wound healing. In particular, two aspects of their histologic distribution within the skin have attracted the attention of researchers to study their wound healing role; they represent up to 8% of the total number of cells within the dermis and their cutaneous versions are localized adjacent to the epidermis and the subdermal vasculature and nerves. At the onset of a cutaneous injury, the accumulation of MCs and release of proinflammatory and immunomodulatory mediators have been well documented. The ro...
