Treg cells or regulatory T cells constitute a large population of cellular infiltrate in atopic/allergic inflammation and a dysregulated immune response appears to be an important pathogenetic factor. Cardinal events during allergic inflammation can be classified as activation, organ-selective homing, survival and reactivation, and effector functions of immune system cells. T cells are activated by aeroallergens, food antigens, autoantigens, and bacterial exotoxins superantigens in allergic inflammation. They are under the influence of the skin, lung, or nose-related chemokine network and show organ-selective homing. (more…)

Asthmatic children who also have Allergic Rhinitis seem to have higher morbidity and to use more healthcare resources. This was further investigated to determine the incremental effect of Allergic Rhinitis on healthcare resource use in children with asthma. The data were from a general practice database in the UK and covered the period 1998–2001. Children aged 6–15 years who had an asthma related visit to their general practitioner at least once during a defined 12 month period were reviewed. (more…)

Classification of bronchial asthma can be based on age, etiology, associated characteristics, or severity. Classifications based on severity have been primarily designed as an approach to asthma treatment. Thus, management of mild intermittent disease may require only bronchodilator treatment, but frequent attacks with or without persistent mild symptoms require a comprehensive approach to controlling inflammation as well as bronchodilator treatment. Severe asthma can become a major clinical problem that requires specialist care and many different approaches to asthma attack treatment. (more…)

There is much controversy as to the role of allergen exposure for the development of atopic sensitization towards this allergen. While in some studies, a clear, almost linear dose-response relation between allergen exposure and sensitization has been found, others described a bell-shaped association with higher levels of exposures relating to lower rates of atopic sensitization. Part of the discrepancy may relate to the type of allergen, since mostly cat but not house dust mite allergy allergen exposure has been shown, in some studies, to exert protective effects at higher levels of exposure.

Leukotrienes are present in increased amounts in exhaled breath condensate (EBC) in patients with asthma. So far, no data have been reported about leukotriene levels in non-asthmatic patients with Seasonal Allergic Rhinitis. The aim of the study was to find out whether the leukotriene levels in exhaled breath condensate were increased in the non-asthmatic adult patients with Seasonal Allergic Rhinitis both during and after the pollen season in comparison with healthy controls, and to assess changes in leukotriene levels after the pollen season. Twentynine non-asthmatic adult patients with Seasonal Allergic Rhinitis and 50 healthy non-smoking controls underwent measurement of exhaled leukotrienes in the exhaled breath condensate during and after the pollen season. Spirometry, skin-prick tests and total IgE were also evaluated. (more…)

Allergic rhinitis is a high-prevalence disease. This high prevalence translates into a high cost to society in terms of overall healthcare utilization, and also a high cost in terms of the quality of life of those who suffer from moderate or severe disease.
Allergic rhinitis has traditionally been divided into seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). This classification is helpful in indicating the season of maximum symptoms and the likely causative allergens immunotherapy. (more…)

Treatment with omalizumab has been shown to reduce serum free IgE concentrations and to have beneficial effects on allergic airway disease. However, its effect on local IgE synthesis is unknown. The authors investigated whether omalizumab therapy diminishes nasal reactivity to allergen and local IgE production. Nineteen patients with perennial allergic rhinitis were treated with intravenous omalizumab every 2 weeks for 26 weeks in an open-label study. (more…)
