The relationship between RAST and skin test results in patients with asthma or rhinitis: a quantitative study with purified major allergens.
Study of the relationship between skin test results and IgE antibody levels is seriously hampered by the use of conventional allergen extracts because the precise amount of relevant allergen for each patient is unknown. ⋯ The major allergens tested show similar biologic activities. In addition to IgE antibody level, total serum IgE and type of IgE antibody response contribute significantly to the skin test threshold for allergens. Even in a system with purified allergens, IgE antibody levels and skin test results are not interchangeable as an indicator of the degree of allergic sensitization.

Randomized Controlled Trial Clinical TrialEffect of six-hour exposure to nitrogen dioxide on early-phase nasal response to allergen challenge in patients with a history of seasonal allergic rhinitis.
Recent studies have suggested that exposure to air pollutants may enhance the airway responsiveness of susceptible individuals to inhaled allergen. ⋯ These results suggest that acute exposure to NO2 at concentrations found at the curbside in heavy traffic during episodes of pollution, may "prime" eosinophils for subsequent activation by allergen in individuals with a history of seasonal allergic rhinitis.

Randomized Controlled Trial Clinical TrialEphedrine-saline nasal wash in allergic rhinitis.
Ephedrine nasal wash (0.25% to 1%) was once used in the treatment of sinusitis and other nasal and paranasal symptoms, but there are no reported controlled trials in allergic rhinitis. ⋯ A 1% ephedrine-saline nasal wash is an inexpensive and effective treatment for allergic rhinitis.
