Apheresis in rheumatoid arthritis.
Plasmapheresis was first introduced as a means of treating the rheumatic diseases in 1976. The rationale of its use was the removal of circulating immune complexes, thus preventing their deposition in the tissue. In rheumatoid arthritis circulating immune complexes do indeed occur and are responsible for some of the serious complications such as vasculitis. Since the T cells are implicated in tissue damage, lymphapheresis and lymphoplasmapheresis were introduced with various success rates. Controlled trials in rheumatoid arthritis have found no value for intensive plasmapheresis, limited value for lymphapheresis and possible, though suspect, value for lymphoplasmapheresis.
