Answer

Modulation of complement is controlled poorly by high doses of glucocorticoids. The usual adult dose of prednisone is 20-40 mg/d (0.3-0.6 mg/kg/d) given daily during hemolysis and changed to alternate days during remission. On this regimen, about 70% of adult patients experience improvement in hemoglobin levels, but long-term therapy is fraught with complications.
