Abstract
Allergic and pseudo-allergic reactions were examined in penicillin factory workers exposed to the dust of preparations of pivampicillin and pivmecillinam. Among 14 workers basophils from five persons showed histamine release by challenge with penicillins, whereas no release was observed in controls of non-atopic individuals not working with the manufacturing of penicillin. Positive skin response was obtained in four workers by path testing and in three persons by scratch test revealing late but no immediate response. All the eight workers who were also exposed to flavour additives used in the penicillin preparations showed histamine release by cocoa and peppermint. The release was not changed by removal of immunoglobulins from the basophil cell surface and the additives caused a similar release in the controls. The histamine release caused by cocoa and peppermint therefore depend on non-immunological mechanisms, i.e. pseudo-allergic reactions which might contribute to the symptoms in penicillin factory workers.
