Circulating IgG-immune complexes (IgG-IC) play a role in the complex e
tiology of C-HUS. In an ongoing open clinical study protein A immunoad
sorption treatment is carried out fox patients who developed severe fo
rms of the syndrome after mitomycin-C chemotherapy. So far, successful
treatment of 14 out of 19 evaluable patients was possible. A protein
A immunoadsorption system was used, allowing processing of large plasm
a volumes to eliminate IgG and IgG-IC from the patient's plasma. (C) 1
