Allergy to pollen grains in certain regions of Rumania

Abstract

In Rumania, as in Hungary and Yugoslavia, the part played by pollen in the etiology of allergic syndromes is of medium importance. Though variations from year to year and from region to region are important, it is possible to establish a mean in the aerobiology of pollen: predominance of tree pollen in April–May, of Poaceae (Gramineae) pollen in May–June–July, and of Poaceae and Asteraceae (Compositae) pollen in August–September. The incidence of pollen allergy in our clinical material on 136 cases of pollinoses, is 9.5% of the total number of allergoses, with variations between 1 and 25%; pollen allergy is negligible in the region of Bucharest, medium in the city of Bucharest, and rather heavy in the sub-Carpathian District C. Allergization with Poaceae pollen is maximum in all areas; tree pollen as well as that of shrubs plays a certain role in the city of Bucharest, but tree pollen alone is important in District C. The association of pollen and fungi sensitization is relatively rare.
