[Occupational respiratory tract allergies].
Professionally conditioned allergoses of the respiratory tract (BK 41) can occur in all industrial regions. The allergoses conditioned by organic dusts of vegetable or animal origin (regions food production, plant production and animal keeping) predominate. Since 1976 the BK 41 has been on the 10th rank of alases, 1977), above all conditioned by an improved establishment. Among the diagnoses bronchial asthma is in the first place. The high proportion of allergoses by cereal constituents is to be led back to the, as a rule, unproblematic allergologic clarification diagnostics. One may conclude that difficulties of the recognition in other allergens condition a considerable dark number, particularly in chemical working materials. The allergoses by cereal constituents are followed by the constituents of the animal epidermis (above all hair of laboratory animals). The remainder -- without any importance of the succession -- belongs to moulds, mites, plant pollen, parasubstituted aromates, chrome and rare allergens. Apart from the slight number of alveolitis diseases the allergoses conditioned by organic dusts belong to the type of early reaction (characteristic representatives: baker's asthma). Problematical are the allergoses of the type of the late reaction. Chemical substances of the hapten type are above all in question (characteristic representative: chrome asthma). Here is most cases expressed irritation effects are present so that this pathogenetic factor is frequently determining without proving any immune-specific effects. The report is based on forgiven criteria of decision.
