“…This has been demonstrated in various studies from different countries. 8,26,28,29 Therefore, although total mite allergen exposure will depend on other sources, we most likely provided valid allergen exposure estimates that are comparable across centers. Finally, we did not collect information on the sampled dust weight, and therefore could not express allergen levels per square meter of mattress surface.…”

“…[2][3][4] D pteronyssinus has long been regarded the predominant house dust mite species in Europe, but during the last decade, it has become clear that in certain European areas, D farinae is common. [5][6][7][8][9] Identification of housing characteristics associated with dust mites is helpful to evaluate the effectiveness of allergen avoidance measures. Some studies have suggested that determinants for allergens of the 2 species are different.…”

“…In the remaining samples, D. farinae and D. pteronyssinus were equally prevalent. Both D. farinae and D. pteronyssinus are present in homes in northern Italy, but D. farinae is the predominant species [47]. The predominant species reported in most studies in England and western Europe are D. farinae and D. pteronyssinus, but E. maynei and storage mites are also present [48][49][50].…”

The most important allergy-causing mites found in homes worldwide are the house dust mites Dermatophagoides farinae, D. pteronyssinus, Euroglyphus maynei, and the storage mite Blomia tropicalis. Most homes contain multiple species. The most prevalent mite species and allergen in homes differ geographically, between homes within a geographical region, and among areas within a home. Therefore, it is important to know which mite species are present in a geographical area when performing diagnostic testing and prescribing immunotherapy. The key factor that influences mite survival and prevalence is relative humidity. Mites are present in homes in humid geographical areas and are rare or absent in drier climates unless humidity is artificially raised. Generally speaking, dust mite allergen levels are low in public buildings and transportation compared to levels in homes.

“…However, mites are the most important source of allergens in settled house dust (5)(6)(7). The most prevalent mites found in the homes of Croatia (8,9) and worldwide (6,10) are Dermatophagoides pteronyssinus and Dermatophagoides farinae.…”

The aim of this study was to determine the level of two major mite allergens Dermatophagoides pteronyssinus (Der p 1) and Dermatophagoides farinae (Der f 1) in 30 urban homes in Zagreb, Croatia, using the enzyme immunoassay with two monoclonal antibodies which has been established as the reference method for indoor allergen analysis. Dust samples were taken by vacuuming a carpeted area and collected on cellulose filters. The ranges of Der p 1 and Der f 1 were (0.1-12.5) microg g-1 (median 0.32 microg g-1) and (0.1-31.2) microg g-1 (median 0.35 microg g-1), respectively. Der p 1 and Der f 1 (>2 microg g-1) associated with increased risk of sensitization to mite allergens were found in approximately 16% homes for each allergen. The sum of allergen (Der p 1 + Der f 1) exceeded the lower threshold in 27% of homes. Analytical evaluation of the ELISA assay showed satisfactory results for precision (intra-assay CV <6.9%, inter-assay CV<13.3%), accuracy (91% to 93%), and sensitivity (2 ng mL-1). The ELISA assay for the measurement of dust mite allergens demonstrated very good analytical characteristics for routine laboratory use, and will provide the essential basis for our future studies of various indoor allergens.
