Allergic rhinitis and asthma are common comorbidities. Like asthma, the presence of a genetic component in allergic rhinitis has been well established. To identify genetic linkage regions unique to allergic rhinitis, as well as those shared by allergic rhinitis and asthma, a genome screen study was conducted. A total of 295 families in the French Epidemiological Study on the Genetics and Environment of Asthma (EGEA) containing 1317 subjects were genotyped for 396 microsatellite markers. The families included had two siblings with DNA available and at least one asthmatic subject. Three definitions of allergic rhinitis were used, two binary and one categorical. To investigate linkages specific to allergic rhinitis (without asthma), linkage analyses were also conducted in 185 families with at most one asthmatic sib. (more…)

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…)

Avoidance of respiratory irritants such as environmental tobacco smoke, whether actively or passively inhaled, is universally recommended and is considered to be fundamentally important in the successful treatment of asthma and allergic rhinitis. Control of environmental airborne allergens such as house dust mites for prevention of asthma, allergic rhinitis, or atopic dermatitis/What Does Eczema Look Like is also widely recommended, although not supported by all studies.

Allergic rhinitis is an inflammatory nasal disorder in which a range of different cells participate. A variety of approaches has been used to monitor nasal inflammation objectively to investigate disease processes and to evaluate the effect of therapeutic intervention. These approaches include nasal lavage, nasal cytology and nasal biopsy, together with the more recently established measurement of nasal nitric oxide (NO) concentration. Although all provide information about nasal mucosal inflammation, the extent of information that can be obtained by each approach, the ease of sampling, and the complexity of sample handling differ.

Non-allergic rhinitis is defined by the absence of positive SPTs or radioallergosorbent test (RAST) to common allergens. Ideally, it should include a negative response to likely nasal allergen challenge since local nasal IgE synthesis has been demonstrated. In practice, the diagnosis is usually dependent on there being no offending allergen apparent from the clinical history. As advancing age is associated with reduced IgE levels and a reduced prevalence of positive SPTs, this may be a confounding factor when assigning rhinitics into atopic and non-atopic subgroups. Such age-related changes contribute to the fall in the apparent prevalence of allergy among persistent rhinitics from around 80% in childhood to below 20% in elderly people. Epidemiologic studies of a population of nearly 3000 patients in Tucson, Arizona, have shown that the prevalence of symptoms of allergic rhinitis is as high as 30% even in those with very low ageadjusted serum IgE scores. This emphasizes that there is a nonallergic subgroup to rhinitis. (more…)

The cross-sensitivity between aspirin and Non Steroidal Anti Inflammatory Drugs in patients who manifest pseudo-allergic reactions to aspirin affecting the respiratory tract occurs because Non Steroidal Anti Inflammatory Drugs, like aspirin, inhibit COX-1, so that arachidonic acid metabolism is diverted towards the 5-lipoxygenase pathway, with resulting increased production of cysteinyl leukotrienes, which mediate the appearance of symptoms such as allergic rhinitis and asthma. Selective inhibitors of Cyclo-Oxygenase-2 or COX-2 were developed primarily to reduce the incidence of adverse events affecting the gastrointestinal tract symptoms, but the possibility that these agents might be less likely to result in other varieties of adverse reaction dependent on COX-1 inhibition has attracted interest. This review examined the evidence for their greater safety in this respect. (more…)
