Abstract
Abstract What is disclosed is a method for the therapy of immunocomplex diseases with an agent which contains Fc-reagents that react with the Fc-part of the antibody contained in the immunocomplex, but which themselves do not posses an immunologically active Fc-part or an Fc-part capable of being activated.

A method for treating an immunocomplex disease in a patient suffering from such a disease, which method comprises locally or parenterally administering to said patient an effective amount of at least one Fc-reagent which reacts directly or indirectly with the Fc-part of the antibody contained in the immunocomplex causing said immunocomplex disease, said Fc-reagent itself not having an Fc-part which is immunologically active or capable of being activated, said Fc-reagent being selected from the group consisting of the complement factors C1q, C3b, and C3d; an antibody which reacts with any of said complement factors C1q, C3b, and C3d; F(ab) 2 -fragments or Fab-fragments of an antibody, obtained by enzymatic fission of the antibody; antibodies, the Fc-part of which has been inactivated by chemical modification; antibodies which are rheumatoid factors; and antibodies produced by the immunization of an animal with immunoglobulin or with a fragment of immunoglobulin having an immunologically-modified activated Fc-part.
