Introduction and objective:
The association between airborne pollen counts or duration of pollen season and allergy symptoms is not always distinguished. The purpose of this study was to examine the correlation between pollen exposure (annual total pollen quantity and main pollen season length) of selected allergenic plants in the atmosphere of Bratislava, and concentration of allergen-specific immunoglobulin E (sIgE) in serum of patients with seasonal allergy during 2002–2003.

Material and Methods:
The concentration of pollen was monitored by a Burkard volumetric pollen trap. At the same time, 198 pollen allergic patients were testing to determine the values of sIgE antibodies against selected pollen allergens; a panel of 8 purified allergens was used.

The highest percentages of sensitization were detected for Poaceae and Ambrosia pollen allergens. The most abundant airborne pollen types were Urticaceae, Betula, Populus, Fraxinus, Pinus and Poaceae. The length of the pollen season varied. The longest pollen season was that of the Plantago – 105 days, and the shortest, Corylus – 20 days. A significant correlation was found between annual total pollen quantity and median sIgE values, especially in 2002.

A strong and significant positive correlation was observed between pollen counts, excluding Betula, and sIgE levels in both analysed years. The correlation was weaker and negative in the case of length of pollen season and sIgE values.
