[Wild silk-induced asthma. A contribution to the knowledge of inhalation allergies caused by wild and tussah silk-filled bed quilts].

In the silk industry occupational IgE-mediated hypersensitivities to different allergens are well known. Since the use of silk waste for the filling of bed quilts a great number of patients suffering especially from silk-asthma could be observed. Immunological investigations showed clearly that in this context sericin and also antigens from an insect of the genus anthrenus in the silk material are of allergenic importance. On the basis of typical case histories from the occupational and private scene the diagnostic difficulties of silk allergy are discussed.
