BACKGROUND: Aeroallergens and food allergens are found to be relevant in atopic dermatitis. The atopy patch test (APT) can help to detect food allergies in children with atopic dermatitis. This study evaluates if the APT is a valuable tool in the diagnostic workup of children with food allergy-related atopic dermatitis. METHODS: 42 children between 6 months and 12 years of age were selected at the Mofid Children Hospital. Atopic dermatitis was diagnosed, and the severity of the disease was determined...

BACKGROUND: Allergies affect children's health as well as their quality of life, stress levels, and family budget. The available literature suggests that family, social and psychological factors are affected by allergic pathologies such as rhinitis, asthma and atopic dermatitis. However, few studies have focused on quantifying such association in child food allergy. This study aims to enhance the understanding of the associations between caregiver variables and children's Food Allergy (FA)...

Food allergy is immediate hypersensitive reactions to ingested foods. Since early diagnosis is effective for disease control, development of an objective diagnostic index is required. Using mediator-lipidomics, we found that levels of the urinary prostaglandin D2 (PGD2) metabolite, tetranor-PGDM, reflected the severity of the allergic symptoms and intestinal mast cell hyperplasia in mice. Repeated oral challenges with ovalbumin promoted allergic symptoms in sensitized mice. Particularly, the allergic mice presented with increased numbers of intestinal mast cells, which strongly expressed hematopoietic PGD synthase (H-PGDS)...

BACKGROUND: Increasing prevalence of allergic diseases has been matched by parallel trends in attention-deficit/hyperactivity disorder (ADHD). However, previous studies concerning the association between ADHD and allergic diseases have been inconsistent. Moreover, it is not clear whether this association is modified by allergic sensitization status. Therefore, we evaluated the association between allergic diseases, allergic sensitization, and ADHD in children. METHODS: We conducted a large-scale cross-sectional, population-based survey to investigate the relationship between allergic diseases, allergic sensitization, and ADHD...

Therapeutic strategy in late 20th century to prevent allergic diseases was derived from a conceptual framework of allergens elimination which was as same as that of coping with them after their onset. Manifold trials were implemented; however, most of them failed to verify the effectiveness of their preventive measures. Recent advancement of epidemiological studies and cutaneous biology revealed epidermal barrier dysfunction plays a major role of allergen sensitization and development of atopic dermatitis which ignites the inception of allergy march...

The morbidity associated with atopic diseases and immune dysregulation disorders such as asthma, food allergies, multiple sclerosis, atopic dermatitis, type 1 diabetes mellitus, and inflammatory bowel disease has been increasing all around the world over the past few decades. Although the roles of non-biological environmental factors and genetic factors in the etiopathology have been particularly emphasized, they do not fully explain the increase; for example, genetic factors in a population change very gradually...

BACKGROUND: The atopic march describes the progression from atopic dermatitis during infancy to asthma and allergic rhinitis in later childhood. In a Canadian birth cohort we investigated whether concomitant allergic sensitization enhances subsequent development of these allergic diseases at age 3 years. METHODS: Children completed skin prick testing at age 1 year. Children were considered sensitized if they produced a wheal 2 mm or larger than that elicited by the negative control to any of 10 inhalant or food allergens...

Allergic diseases are among common clinical conditions, affecting millions of children and adults throughout the world. Food allergies, skin allergies (atopic dermatitis), and respiratory allergies (allergic rhinitis and asthma) are the common types of allergies. Recently discovered cytokines IL-17 and IL-33 have been found to play an important role in the pathogenicity of various hypersensitive disorders. After exposure to allergens or infection with parasites or viruses, IL-17 and IL-33 producing cells, such as Th17 and specialized epithelial cells respectively, become activated and trigger the pathogenic immune responses in different susceptible conditions...

BACKGROUND: While allergic sensitization and atopic dermatitis (AD) are known to increase the risk for allergic diseases, the impact of different temporal and clinical patterns of sensitization and AD is less well defined. OBJECTIVE: We investigated patterns of sensitization and AD from early infancy to age 3, and the differential risk for developing allergic diseases within each pattern in a general cohort. METHODS: Children (n=2629) from the Canadian Healthy Infant Longitudinal Development (CHILD) Study underwent skin prick tests and were assessed clinically for AD at ages 1 and 3 years...

The rising burden of allergic diseases in childhood requires a compelling need to identify individuals at risk for atopy very early in life or even predict the onset of food allergy and atopic dermatitis since pregnancy. The development and clinical phenotypes of atopic diseases in childhood depend on a complex interaction between genetic and environmental factors, such as allergen exposure, air pollution, and infections. Preventive strategies may include avoidance measures, diet supplements, and early complementary food introduction...

Multiple risk factors have been associated with the development of atopic dermatitis (AD). Recent advances in understanding the role of genetics in this disease have been made, with discovery of the filaggrin (FLG) gene as the most notable so far. In addition to FLG gene mutations as a risk factor for AD, a positive family history of atopic or allergic disease in either parent, has been shown to confer a greater risk of developing AD. Atopic dermatitis usually presents early in life and is thought to represent the initial-step in the "atopic march" which is characterized by the development of other atopic diseases later in life such as asthma, allergic rhinitis and/or rhinoconjunctivitis, food allergies and hay fever...

The manifestation of atopic dermatitis (AD) is initially nonatopic eczema in early infancy; the manifestations subsequently change in age-specific stages. Since allergen-specific T-helper 2 cells appear in the fetus primarily after the third trimester of pregnancy and rapidly mature during the first 6 months of life, different timings of tobacco smoke exposure may have different effects on AD. In this study, we investigated whether the timing of fetal or/and infantile tobacco smoke exposure affects the cumulative incidence of atopic eczema/dermatitis syndrome (AEDS) in infants in Japan...
