Circulating immune complexes in rheumatoid arthritis. Selective removal by cryogelation with membrane filtration. 1982

We have developed a system of extracorporeal circulation that removes proteins of the molecular weight of the circulating immune complexes of rheumatoid arthritis by cryogelation with hollow-fiber membrane filtration. A 52-year-old woman with a 36-year history of severe, unremitting, high-titer, seropositive rheumatoid arthritis who had failed to respond to anti-inflammatory, antirheumatic, and cytotoxic drugs was chosen for a trial of this system. A rapid and sustained decrease in circulating immune complexes as measured by C1q binding occurred, accompanied by a much slower improvement in clinical factors of disease activity. Rheumatoid factor changed very little and loss of other serum proteins by the procedure was relatively modest. This new procedure was successful in removing circulating immune complexes in a patient with rheumatoid arthritis, and in inducing a remission in one who has not had such in 36 years, while sparing volume and other plasma proteins.

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. Rheumatoid Arthritis
D015922 Complement C1q A subcomponent of complement C1, composed of six copies of three polypeptide chains (A, B, and C), each encoded by a separate gene (C1QA; C1QB; C1QC). This complex is arranged in nine subunits (six disulfide-linked dimers of A and B, and three disulfide-linked homodimers of C). C1q has binding sites for antibodies (the heavy chain of IMMUNOGLOBULIN G or IMMUNOGLOBULIN M). The interaction of C1q and immunoglobulin activates the two proenzymes COMPLEMENT C1R and COMPLEMENT C1S, thus initiating the cascade of COMPLEMENT ACTIVATION via the CLASSICAL COMPLEMENT PATHWAY.
