Abstract

|
|
To evaluate the allergenic significance of pollens as a causative allergen in childhood respiratory allergic diseases, skin scrach test with inhalant allergens(tree, wee, grass pollens, house dust mites and fungi) and radioimmunoassay for
detection
of
allergen specific IgE were performed. In the 116 atopic children tested we compared the clinical and immunological characteristics between house dust mite-nonsensitive pollen-sensitive atopics(group I, N=17) and house dust mite only sensitive
atopics(Group II, N=13).
@ES The results are as follows:
@EN 1. Thirteen out of seventeen cases in Group I and bronchial asthma and four had rhinitis only; all in Group II had bronchial asthma. The age distribution was 4-14 years in each study group. and in Group I, 8 cases(47.1%) were under 7 years of
age.
2. Nine cases(52.9%) in Group I experienced seasonal respiratory allergic diseases, with their symptoms aggravated in group (3 cases), summer (4 cases) and autumn(2 cases) for at least 2 consecutive years.
3. Allergy skin tests showed willow and hop japnaese to be the most prevalent sensitizing pollens(positive rate was 47.1%) and birch, hazel, oak, poplar, rye grass, timothy, mugwort were positive in over 25% of cases studiedd.
4. Specific IgE responses to several species of pollens were relatively weaker than those to house dust mite in these caes.
In conclusion, the pollens may act as causative allergens in Korean children especially some localities.
