House dust mites, pets, microorganisms such as fungi and bacteria are the main causes of indoor allergens. The diseases correlated to the presence of these allergens are of increasing importance in public health as well as in occupational medicine. Indoor allergens are widespread in residential buildings as well as in public and in office buildings. Surveys conducted in Italian office buildings demonstrated detectable allergen concentrations in most of these buildings. In some cases, the concentrations were higher than the proposed risk threshold for allergenic sensitisation or for the elicitation of symptoms in allergic individuals. The health effects of exposure to indoor allergens mainly include allergic asthma and rhinoconjunctivitis caused by IgE reactions in predisposed subjects. Moreover, exposure to indoor biological agents can cause extrinsic allergic alveolitis or other effects such as the so-called "humidifier fever" due to contaminated humidifiers. Standardized methods for the measurement of indoor allergen levels are available, and may be useful for the diagnosis and treatment of individual allergic patients or for group studies in order to evaluate the relationship between allergen indoor levels and health effects or to assess indoor allergen levels in private or public buildings for preventative purposes.
