    Abstract:
    We have compared the effect of therapy with immunosuppression alone to immunosuppression plus plasma exchange on the clinical course and rate of disappearance of antibody in 17 patients with anti-glomerular basement membrane (anti-GBM) antibody-induced renal disease. Patients receiving immunosuppression (n = 9) and those receiving plasma exchange (n = 8) were similar in terms of entry clinical characteristics, pulmonary manifestations and complications associated with therapy. Rate of disappearance of anti-GBM antibody as estimated from serial estimates of antibody binding was significantly more rapid in patients receiving plasma exchange, and mean serum creatinine in these patients at end of therapy was half that of the patients receiving immunosuppression alone. Analysis of clinical and pathologic values at study entry, however, indicated that the percent of crescents on initial renal biopsy and entry serum creatinine correlated better with outcome than did therapeutic modality. Thus, though plasma exchange may offer some advantage over immunosuppression alone in the treatment of this disease, degree of pathologic involvement appears to be the major factor affecting outcome. Patients with low cresents (less than 30%) and well preserved function did well with either treatment, while patients with severe crescentic involvement and impaired glomerular filtration rate did poorly.
