Plasmapheresis in the management of acute systemic lupus erythematosus?

Eight patients with systemic lupus erythematosus (S.L.E.) have been treated with plasmapheresis. In four patients in whom immunochemical studies indicated high levels of circulating immune complexes, the removal of 5-8 litres of plasma weekly produced a striking clinical and immunochemical improvement. The four other patients, with only minor complement disturbances and no direct evidence of circulating immune complexes, could not be shown to benefit from plasmapheresis and one patient in this group died of cerebral lupus despite intensive treatment with cytotoxic drugs. It is concluded that plasmapheresis may be of value as an adjuvant to the treatment of acute S.L.E.
