Prevalence of house dust mites in the homes of atopic dogs in Finland

Studies on the longitudinal changes in sensitization to aeroallergens in adult populations are sparse. The aim was to evaluate changes in sensitization to aeroallergens [birch, timothy, cat and house dust mite (HDM)] in an unselected adult population aged from 31 to 46 years. Data were gathered from a cohort of adults (Northern Finland Birth Cohort 1966) who had been skin prick tested (SPT) with birch, timothy, cat and HDM allergens at the age of 31 years and at age 46 (n = 5484 and 5373 respectively). Data from both time points were available for 3409 participants, who made up the cohort of the longitudinal study. The overall prevalence of sensitization to any of the selected allergens was 30.3% (n = 1661) in 31-year-olds and 30.7% (n = 1649) in 46-year-olds. In general, men were more sensitized (P < 0.001) and also had more polysensitization (P < 0.001) compared to women. In longitudinal sub-population incidence of sensitization was 7.1%. Birch was the most prevalent new sensitizer, however, the difference was not statistically significant when compared to cat. We conclude that new sensitization, demonstrated by positive findings in SPT, can still occur in middle age and this should be taken into account when managing allergic manifestations in adults as sensitization can be considered the first step in developing clinical allergy.

Introduction. This work is devoted to study the microbiological composition of the air 110 dwellings in the city of Vladivostok and the assessment of the impact of various factors on the microbiological condition of premises. The study is aimed at obtaining information about the real sanitary and hygienic conditions of the exploited residential area and identifying patterns of changes in environmental indicators from design decisions, building parameters and conditions of its operation. Research statistics are the result of field research with laboratory processing of the samples obtained. The relevance of scientific work also lies in the possibility of further factor analysis and verification of sanitary norms and rules with the practice of real design and operation of residential buildings. Materials and methods. Surveys were conducted on the basis of air sampling with subsequent assessment of the content of bacteria in the air of apartment buildings of different types, built at different times from different materials. Results. The section presents analytical data on the content of three main groups of bacteria in the air of residential premises located on the territory of Vladivostok. Based on the accumulated data, a comparative analysis was carried out to establish a correlation between the number of microorganisms in the air and the city area, the type of building material of the house, the density of apartment occupancy, and the presence of pets. Conclusions. Data on the influence of apartment occupancy density on the sanitary and microbiological situation were obtained. The assessment of the influence on the density of microbiological contamination of such factors as: the presence of pets, the type of building materials from which buildings are built, as well as the territorial location of the surveyed apartments.
