Cyclosporin A and therapeutic plasma exchange in the treatment of severe systemic lupus erythematosus.

Despite treatment with intensive immunosuppressive drug regimens, often the prognosis of patients suffering from systemic lupus erythematosus (SLE) is poor. Side effects such as infections and malignancies often occur. It was the aim of this trial to assess the effect of immunosuppression, in particular with cyclosporin, and the efficacy, safety, and clinical utility of intermittent treatment with therapeutic plasma exchange (TPE) in comparison to previous intensive therapy strategies using corticosteroids, azathioprine, and/or cyclophosphamide. In this prospective trial, 28 patients (24 women, 4 men, aged 36.3 +/- 11.8 years at the diagnosis of SLE) were treated for up to 10 years with drug regimens out of corticosteroids, azathioprine, and/or cyclophosphamide. Then, over a period of up to 8 years, in addition to conventional therapies, especially in active stages of the disease with extremely high concentrations of anti-DNA, anti-nuclear antibodies, and circulating immunocomplexes, TPE sessions were carried out depending on symptomatology. In addition, the patients received cyclosporin. Compared with previous treatment modalities, clinical symptoms improved more quickly and more effectively. During the study period of a mean of 5 years, corticosteroids, azathioprine, and cyclophosphamide were reduced by 40 to 100%. No severe side effects were seen. In acute stages of SLE and in forms with persistently high antibody levels, the addition of TPE sessions and cyclosporin as the basic immunosuppressive drug is mostly very effective with regard to improving clinical symptomatology.
