The epithelial barrier: The gateway to allergic, autoimmune, and metabolic diseases and chronic neuropsychiatric conditions.

Since the 1960 s, our health has been compromised by exposure to over 350,000 newly introduced toxic substances, contributing to the current pandemic in allergic, autoimmune and metabolic diseases. The "Epithelial Barrier Theory" postulates that these diseases are exacerbated by persistent periepithelial inflammation (epithelitis) triggered by exposure to a wide range of epithelial barrier-damaging substances as well as genetic susceptibility. The epithelial barrier serves as the body's primary physical, chemical, and immunological barrier against external stimuli.

Atopic dermatitis: Correlation of distinct risk factors with age of onset in adulthood compared to childhood.

Background: Atopic dermatitis (AD) has long been regarded as a primarily pediatric disease. However, there is growing evidence for a high rate of adult-onset AD. We aimed to characterize factors associated with adult-onset versus childhood-onset AD and controls.

Predicting dupilumab treatment outcome in patients with primary diffuse type 2 chronic rhinosinusitis.

Background: Chronic rhinosinusitis with a type 2 inflammatory pattern (T2CRS) is believed to be restricted to the nose and sinuses and associated with polyps, without clear serologic markers. Dupilumab is a promising new therapy in difficult to treat T2CRS. No factors are known to predict dupilumab treatment outcome.

Risk factors for severe systemic sting reactions in wasp ( spp.) and honeybee () venom allergic patients.

Background: Hymenoptera stings are a major cause of anaphylaxis. Various risk factors are discussed in literature. This study aims to investigate potential risk factors for severe sting reactions in wasp ( spp.
