Decrease in circulating immune complexes during hemodialysis.

Raji cell radioimmunoassay and Clq solid phase radioimmunoassay were used to determine serially circulating immune complexes in a patient with rapidly progressive glomerulonephritis who was receiving hemodialysis therapy. Initiation of hemodialysis was associated with a significant decrease in detectable immune complexes which, in turn, was associated with improvement and stabilization of renal function. We suggest that hemodialysis may remove immune complexes from the circulation and that it could be of therapeutic benefit in selected patients with presumed immune complex-mediated glomerulonephritis.
