Allergic, Rheumatic, and Etiologically Unclarified Joint Inflammations
Repeated parenteral administrations of serum, a protein foreign to the body, often lead to joint inflammation. This process may serve as a paradigm for the explanation of some inflammatory processes taking place in the joint capsule. Two to eight days after repetition of an intramuscular injection of serum against tetanus, some individuals experience swelling of joints associated with urticaria of the skin and exudation in body cavities. This syndrome ist termed serum sickness. Pirquet  demonstrated that the concurrent changes represent an allergic phenomenon which is elicited as an anaphylactic reaction by some organs or structures to the injected foreign protein. The foreign serum or plasma is countered by antibodies, either already available or produced within a few days . The resulting antigen-antibody complexes are deposited in the wall of blood vessels, the glomeruli of the kidneys, the reticuloendothelial cells of the liver and spleen, and the synovial cells of the joint capsules.
