Abstract
The technique of cryofiltration has been applied in the treatment of cryoglobulinemia. Good clinical improvement has been demonstrated accompanied by decreases of cryoglobilin levels. The combination therapy with cytotoxic drugs performed at adequate frequency and volume processed maintained relief of symptoms and serologic improvement. The cryofilter demonstrates good selectivity for cryoglobulin removal in cryogel, comfirmed by electrophoretic analysis of both the cryogel and filtrate from the cryofilter used clinically. Plasma cryofiltration appears to be a safe alternative to plasma exchange, requiring no replacement fluid.
