Plasma exchange in the treatment of nonadvanced stages of progressive systemic sclerosis.
Ten patients suffering from progressive systemic sclerosis, who responded poorly to conventional therapy, underwent plasma exchange (PE) therapy in conjunction with drug therapy. The frequency of PE was twice weekly for 4-6 weeks, two or three times per year, with a summer interruption, when in our own experience a spontaneous relief of symptoms occurs. To judge the efficacy of our therapeutic device, we assessed several laboratory and clinical parameters before and after therapy. The changes in circulating immune complexes, in IgG and IgA, and in some functional indices were significant (P less than 0.001). Eight of 10 patients improved satisfactorily. The remaining two did not improve sufficiently to continue the apheretic treatment. In conclusion, our study suggests that the PE, together with conventional therapy, can be an effective therapeutic device in the treatment of progressive systemic sclerosis.
