[The role of antiglobulin antibodies in pathophysiology of various internal diseases].
Antiglobulins are a heterogenous group of antibodies specific for a large number of antigenic determinants on the heavy chains of various classes and on light chains. They are capable of reacting with hidden antigenic determinants of gamma globulins after they have been exposed by the action of proteolytic enzymes or after antigen-antibody reaction during which changes occur in the spatial configuration of the Fc fragments of immunoglobulin causing that they assume immunogenic properties. Antiglobulin antibodies against episomes in the Pab fragment of other antibodies have a strong regulatory influence on the immune response in view of their ability of specific interference with the response to a specific antigen. Antiglobulin antibodies may exert a protective effect but also a pathogenic effect. The latter has been demonstrated in atopic diseases, in IgA glomerulonephritis, in rheumatoid arthritis, in infectious mononucleosis, cryoglobulinaemia, in patients with IgA deficiency associated with presence of antiglobulin antibodies to IgA after transfusion of plasma or intravenous infusion of gamma globulins containing IgA.
