[The manifestation of immune reactions and the chromium content of the blood in patients with occupational allergic dermatoses].

One of the mechanisms responsible for occupational dermatoses of constructors in contact with Cr-containing substances is supposed to be antibodies production as a result of Cr ion migration in the blood. The authors' measurements led them to the conclusions that no significant rise in blood Cr content occurs with an increase in the service duration, there is a close relationship between Cr blood concentrations and specific skin tests as well as between blood Cr and allergic manifestations. In patients with initial and established forms of occupational dermatosis the number of positive responses to Cr skin tests and frequency, intensity of allergic reactions grow with elevation of Cr concentrations in the blood. It is inferred that the test for blood chromium may serve an additional criterium of early diagnosis of occupational dermatosis.
