C4A and cryoglobulinemia: Among SVR patients with baseline cryoglobulinemia, at 12 weeks posttherapy, all signals for cryoglobulinemia had been reversed, as the levels of C3, C4, IgG, IgM and RF (3, 10) all changed in those without 12-week posttherapy cryoglobulinemia, and the reversals persisted for all parameters except for C3 and RF until 48 weeks posttherapy for those without any posttherapy cryoglobulinemia.
