Seasonal variation of airway function in allergic rhinitis

Journal of Allergy and Clinical Immunology, 1986
We set out to examine seasonal variation in airway bronchoconstriction in patients with seasonal allergic rhinitis. Airway conductance and response to methacholine challenge were measured during pollen season, as well as in winter when pollen exposure was not present. Airway conductance and spirometry were performed on 17 subjects during allergy season

Regulation of Proinflammatory Cytokines in Seasonal Allergic Rhinitis

International Archives of Allergy and Immunology, 1999
<b>Background: </b>Mediators and cytokines have been demonstrated to be released due to nasal allergen exposure in sensitized subjects, but little is known about the release of cytokines and their antagonists under natural conditions. <b>Methods: </b>Mediators – histamine, eosinophilic cationic protein (ECP), leukotrienes (LT ...

Seasonal increase of bronchial reactivity in allergic rhinitis

Journal of Allergy and Clinical Immunology, 1987
Twenty-seven patients with hay fever had a carbachol inhalation challenge both out of season and during the pollen season. Eight patients with allergic asthma were used as a control group. Only three patients (11.1%) demonstrated a value of a provocative dose causing a 20% fall in FEV1 in the asthmatic range out of pollen season, but during pollen ...

TRPV1‐mediated itch in seasonal allergic rhinitis

Allergy, 2009
Background:  Patients with allergic rhinitis may be abnormally sensitive to stimulation of the ion channel transient receptor potential vanilloid‐1 (TRPV1).Aim of the study:  To examine effects of various TRP ion channel activators on sensory symptoms in allergic rhinitis prior to and during seasonal allergen exposure.Methods:  Nasal challenges were ...

Pharmacotherapy of Perennial and Seasonal Allergic Rhinitis

Clinical Immunotherapeutics, 1995
The options for pharmacotherapy of both perennial and seasonal allergic rhinitis continue to expand rapidly. The classic antihistamines will retain a place as effective drugs. They are without serious adverse effects, and are often available without a physician’s prescription.

Treating the Student with Seasonal Allergic Rhinitis

Pediatric Asthma, Allergy & Immunology, 1996
Students with seasonal allergic rhinitis may experience decreased academic performance and productivity, not only as a result of the disease itself, but often also because of the sedative side effects of some of the antihistamines used in its treatment.

Birth season variation in asthma and allergic rhinitis

Clinical & Experimental Allergy, 1989
SummaryThe prevalence of asthma and allergic rhinitis was analysed in relation to birth month in two cohorts of 18‐year‐old males born in 1953 (n= 55 393) and 1963 (n= 57 150), in school children (n= 1984) and in children with defined specific allergies (n= 1080). Among the 18‐year‐olds, a marked variation with respect to birth season was only found in

Seasonal variations of total histamine in patients with seasonal allergic rhinitis

Clinical & Experimental Allergy, 1983
SummarySeasonal variations of total blood histamine were examined in twenty patients with seasonal allergic rhinitis (Japanese cedar pollinosis). In blood specimens taken in the pollen season of 1978, the symptom‐free season of 1978. and the pollen season of 1979, the mean values of blood histamine were 61.6, 50.0 and 84.2 ng/ml respectively.

Seasonal allergic rhinitis - a review of current therapy

Allergy, 1996
Epidemiological studies in many countries strongly suggest an increase in the prevalence of seasonal allergic rhinitis, particularly in urban communities. The mechanisms of allergic rhinitis have been the subject of much research, elucidating symptomatology and improving the focus of therapeutic strategies.
