[Immunologic mechanisms of the development of nonspecific aortoarteritis].

It has been shown that patients with nonspecific aortoarteritis undergoing acute and subacute stages of the process demonstrate sensitization to collagen, types I and III. The activity of inflammation was discovered to affect the disease progression and involvement of new arterial areas. Marked suppression of leukocyte migration in response to collagen, types I and III, in patients with nonspecific aortoarteritis points to a high probability of further disease progression.
