[Use of plasmapheresis in therapy of systemic lupus erythematosus: a controlled study].

The effectivity of a combination of various plasma exchange regimens in combination with immunosuppressive medication consisting of corticosteroids and cyclophosphamide was tested in patients with severe systemic lupus erythematosus (SLE) the symptoms of which were found to be refractory to conventional immunosuppressive treatment administered orally. The patients were then submitted in a controlled manner to the following treatment modalities: 1. consecutive plasmapheresis (plasma exchanges every 2 to 3 days during a period of 2 to 3 weeks) with a continuation of immunosuppressive therapy administered orally; 2. chronic intermittent treatment (once per week) with parallel immunosuppression; 3. 2 plasmaphereses followed by an i.v. cyclophosphamide bolus. Only the third approach resulted in a stable and persistent clinical and serological improvement of disease activity.
