allergic rhinitis is an extremely common disease worldwide. aeroallergens are very often involved in allergic rhinitis and their prevalence may vary in differ¬ent regions. the causative allergens of allergic rhinitis in our area are unknown. the purpose of this study was to determine the prevalence of skin reactivity to different aeroallergens in patients with allergic rhinitis in the city of s...

BACKGROUND The purpose of this study was to examine the risk of nasopharyngeal carcinoma (NPC) after a diagnosis of allergic rhinitis. METHODS We identified 67,532 patients with allergic rhinitis (allergic rhinitis cohort) and a 135,064 control cohort with the same mean age and sex ratio by using a Taiwan Longitudinal Health Insurance Database (LHID) sample from 2000 to 2005. RESULTS After ...

BACKGROUND Breastfeeding has been linked to a reduction in the prevalence of allergy and asthma. However, studies on this relationship vary in outcome, which may partly be related to differences in breast milk composition. In particular breast milk composition may differ between allergic and non-allergic mothers. Important components that may be involved are breast milk proteins, as these are k...

Primary allergic sensitization--IgE formation after Ag exposure--is fundamental in the development of allergic respiratory disease. With the rising prevalence of asthma and allergic rhinitis, improved understanding of the determining factors for allergic sensitization is needed. Human epidemiologic studies suggest high-dose allergen exposure may paradoxically protect against sensitization. Pros...

introduction: chronic suppurative otitis media (csom) is considered one of the most common causes of acquired hearing impairment in developing countries. csom is a multifactorial persistent inflammatory disease of the middle ear. a distinct pathophysiologic mechanism linking allergic rhinitis (ar) and csom remains to evolve. the purpose of this study was to investigate the association between a...

Asthma and allergic diseases cases have risen in recent decades. Plant pollen is considered as the main aeroallergen causing allergic reactions. According to available data, urban residents experience more respiratory allergies than rural residents mainly due to the interaction between chemical air pollutants and pollen grains. This interaction can occur through several mechanisms; chemical pol...

BACKGROUND Epidemiological research reveals that the incidence of allergic diseases and that of autoimmune diseases have been increasing in parallel, raising an interest in a potential link between the two disorders. However, the relationship between Th2-mediated allergic disease and Th1-mediated juvenile idiopathic arthritis (JIA) remains unclear. This population-based case-control study was a...

BACKGROUND Indoleamine 2,3-dioxygenase (IDO) is a tryptophan catalyzing enzyme. It has been suggested that it has a role in lower airway allergic inflammations, but its role in allergic rhinitis has not been investigated. OBJECTIVE Our aim was to evaluate the expression of IDO in the nasal mucosa of allergic rhinitis patients allergic to birch pollen during peak exposure to birch pollen aller...

BACKGROUND A clinically relevant relationship between classic asthma and allergic rhinitis has been reported. However, the possible link between cough variant asthma (CVA) and allergic rhinitis remains unknown. OBJECTIVES To clarify the prevalence and clinical relevance of perennial allergic rhinitis or seasonal allergic rhinitis in CVA patients compared to classic asthma patients. METHODS ...

introduction: the prevalence of allergic airway diseases has dramatically increased in recent years all over the world. murine models of allergic airway inflammation have provided helpful information about treatment and cellular and molecular mechanisms of the disease. previous published works using murine models to investigate latex allergy did not introduce a complete characteristic eosinophi...
