“…Pollens appear seasonally and are reflected in the symptoms of patients with SR living in temperate climates. Recent studies have shown that grass pollen in Turkey [4,5,6,7,8], birch and grass pollens in northern Europe [17,18,19,20,21], ragweed pollen in America [22], and mugwort and olive pollens in the Mediterranean area [23,24,25,26,27] are the most common and important allergens of these regions. Since Turkey is located between Europe and Asia like a bridge, all four seasons can be present in different regions of the country at the same time of the year.…”

Background: The aim was to determine the clinical characteristics of patients with seasonal rhinitis (SR) and to disclose differences in the treatment of SR between an adult allergy clinic and other clinics over time. Methods: A retrospective study was conducted based on clinical records of 774 out of 955 patients diagnosed with SR in an adult allergy clinic between 1 January 1991 and 31 December 2003. Results: The mean age of the patients was 29.1 ± 9.29 years and 62.7% were female. The most common major complaints of the patients were nasal symptoms in 82.3%. The mean duration of the disease was 6.76 ± 6.8 years. The patients were symptomatic with a mean of 3.5 ± 1.7 months a year, mostly during the period between April and July. Skin prick tests were positive in 685 patients (90.3%), where the most common sensitivity was against timothy grass (85.1%). The most common accompanying allergic diseases were food hypersensitivity in 14%, bronchial asthma in 13.4%, and drug allergy and/or intolerance in 9.6%. Although the use of specific immunotherapy and short-acting sedative antihistamines decreased over time, the use of nasal steroids and long-acting nonsedative antihistamines tended to increase before admission to our clinic. Older age (OR: 1.77, 95% CI: 1.06–2.94), presence of familial atopy (OR: 1.72, 95% CI: 1.04–2.85), respiratory symptoms (OR: 2.10, 95% CI: 1.75–2.50), ocular symptoms (OR: 0.77, 95% CI: 0.61–0.98) and metal allergy (OR: 0.25, 95% CI: 0.07–0.89) were associated with the development of asthma in patients with SR. Conclusion: SR lasts approximately 3.5 months and the main cause in Ankara, Turkey is grass pollen sensitivity. Patients with any other allergic conditions make up 39.8% of the patients. SR patients are referred to allergy clinics quite late, which might be due to SR not being considered as a serious disease.

The number of individuals allergic to plant pollen has recently been on a constant increase, especially in large cities and industrial areas. Therefore, monitoring of airborne pollen types and concentrations during the pollen season is of the utmost medical importance. The research reported in this paper aims to determine the beginning, course and end of the pollen season for the plants in the City of Zagreb, to identify allergenic plants, and to assess the variation in airborne pollen concentration as a function of temperature and precipitation changes for the year 2002. A volumetric Hirst sampler was used for airborne pollen sampling. Qualitative and quantitative pollen analysis was performed under a light microscope (magnification x400). In the Zagreb area, 12 groups of highly allergenic plants (alder, hazel, cypress, birch, ash, hornbeam, grasses, elder, nettles, sweet chestnut, artemisia and ambrosia) were identified. Birch pollen predominated in spring, the highest concentrations being recorded in February and March. Grass pollen prevailed in May and June, and pollen of herbaceous plants of the genus Urtica (nettle) and of ambrosia in July, August and September. Air temperature was mostly higher or considerably higher than the annual average in those months, which resulted in a many days with high and very high airborne pollen concentrations. The exception was April, when these concentrations were lower because of high levels of precipitation. This also held for the first half of August and the second half of September. Pollen-sensitive individuals were at high risk from February till October because of the high airborne pollen concentrations, which only showed a transient decrease when the temperature fell or there was precipitation.
