Introduction. Data on the importance of sensitization in atopic dermatitis (AD) is controversial. It is the question which AD is atopic disease. Aim. To analyze the impact of sensitization to aeroallergens in AD. Is there a similar pattern of sensitization in patients with AD, allergic rhinitis (AR) and asthma? Material and methods. We studied 4783 participants (29.46% 6-7 yo, 27.98% 13-14 yo, 22.73% adults) in 8 urban and 1 rural area. Allergologist diagnosed AD based on Hanifin-Rajka's criteria. Skin prick tests (SPT) was performed with the 15 most common aeroallergens. SPT was positive when the wheal was 3 - 5 mm, remarkable positive ≥ 6 mm. Results. AD was diagnosed in 6.5% of patients, asthma in 10.6%, AR in 28.9%. A positive SPT to at least one aeroallergen was in 45.8% (6-7 yrs 39.3% 48.6% 13-14 years of age, adults 48.2%). The most sensitizing were D. pteronyssinus (24.7%), D. farinea (21.6%) and grass/grain (22.3%). SPT was positive in 66.9% of patients with AD, 84.63% AR, 70.5% asthma. In patients with AD the most sensitizing were D. pteronyssinus (33.1%), D. farinea (33.2%) and grass/grain (30.6%). Sensitization to Cladosporium (OR 2.03), D. farinea (OR 2.0), cat (OR 2.01) and birch (OR 1.98) had the greatest impact on AD. Conclusions. We confirmed the high prevalence of sensitization to aeroallergens in patients with AD, although less than in AR and asthma. Sensitization to aeroallergens was a risk factor for AD. In the general population the greatest impact on the presence of AD was sensitization to Cladosporium, D. farinea, cat and birch. [ABSTRACT FROM AUTHOR]

Introduction. Over the last few decades the prevalence of allergic diseases has dramatically increased. This situation makes it necessary to conduct international, standardized, randomized epidemiological studies Aim of the study. The aim of the study was to assess the prevalence of bronchial asthma in Poland. Material and methods. The study was conducted with the use of a translated and validated questionnaire survey developed for international ECRHS II and ISAAC studies. The study was performed in 9 selected regions in Poland (8 urban regions and 1 rural region). The respondents were obtained from a random multistage selection and they were proportionally stratified on the basis of their PESEL (Identification Number) operator. The completed questionnaires were collected from 18,617 respondents and nearly 25% of them subsequently underwent a medical examination. Results. Asthma was self-reported in 4.72% of the subjects land was diagnosed in 11% of subjects after the ECAP medical examination. Wheezing and whistling during the past 12 months was reported by 12.4% of adults and in the whole life by 18.8% of children 16.1% of adolescents. The association between asthma and allergic rhinitis was declared by 73.6% of patients. Conclusions. Asthma is a prevalent disease in the Polish population and should be considered a significant social problem. Measures for early detection and prevention of asthma should be introduced.
