[Pathophysiological implications of antigen-antibody complexes (author's transl)].

Seventy years after the description of the Arthus phenomenon, the concept of immune complex mediated pathology is widely recognized in clinical pathophysiology. The availability of methods for the detection of soluble immune complexes opens new paths for clinical investigation in this field. This is demonstrated for systemic lupus erythematosus, viral hepatitis B and herpes zoster disease. New experimental approaches deal with the question of tissue localization of immune complex mediated diseases, e.g. through affinity of antigens for certain tissue structures.
