Aim

The aim of the present study was to determine the frequency of positive skin-test reactions to selected summer pollen allergens.

Materials and Methods

1337 patients from Warsaw and its immediate vicinity with a preliminary laryngologic diagnosis of upper-airways allergy were examined in the E. N. T. Allergy Clinic, Medical School, Warsaw. Their examination involved subjective and objective studies as well as the scarification test, using 47 Allpyral allergens. After 20-30 minutes the test scores were read and the results of positive skin test reactions counted. The frequeny of the positive reactions was demonstrated on a four-grade scale: "0" (0-2 mm), "+" (3-5 mm), "++" (6-10 mm), and "+++" (over 10 mm skin test reaction).

Results

680 (50.9%) patients showed positive skin-test reactions. This subgroup reacted to following to the allergens of grasses (52.2%), rye (51.8%), and trees (12.4%). Other plants provoked the following positive reactions: oat grass (49.3%), timothy grass (45.0%), ash-tree (3.7%), willow (2.2%), meadow grass (52.2%), orchard grass (59.4%), wheat (47.2%), birch (10.4%), a combination of five flowers (20.3%), tussock-grass (Poa; 48.1%), rye-grass (37.1%), soft grass (45.0%), hazel (6.0%), white poplar (7.2%), golden rod (9.6%), fescue (50.7%), alder (7.5%), linden (1.2%), maple (2.8%), and ambrosia (4.6%). House-dust mites provoked 17.8% (Dermatophagoides pteronyssinus) and 21.8% (Dermatophagoides farinae) of positive skin-test reactions, respectively.

Conclusion

  1. Grass and corn inhalatory allergens are the most frequent offenders.
  2. Trees and weeds sensitize less frequently than house-dust allergens.
