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…)

There is increasing evidence relating body mass index to the prevalence of asthma and incidence of asthma in children and adults, males, and more consistently, in adolescent females. It is unlikely that the association is attributable to reverse causation, i.e. that asthma and obesity because of exercise-induced asthma symptoms. Rather, weight gain can antedate the development of asthma. Weight reduction among asthmatic patients can also result in improvements of lung function. (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…)

The two strongest risk factors for asthma in childhood are a family history and immediate hypersensitivity to common allergens. This immune response includes both IgE antibodies and helper T cells type 2 (Th2), both of which are thought to contribute to the inflammation in the respiratory tract. Children with asthma who mount an immune response to inhalant allergens have an increased risk of developing asthma because of this combination of genetics and exposure. However, it is sensitization to indoor allergens (e.g. dust mites, cats, dogs, and cockroaches) that is strongly associated with asthma. (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…)

Asthma is a continuing problem for healthcare, particularly in the industrialized world. Some 150 million people are estimated to suffer from asthma worldwide, with 5.2 million sufferers in the UK. Hospital admissions for asthma number 69 000 per annum in the UK, including 28 500 children. Approximately 1400 people die from asthma in the UK annually, of whom over 30% are under the age of 65. Asthma costs the UK National Health Service almost £90 million per annum (statistics from Asthma UK, http://www.asthma.org.uk). (more…)
