Erythrocytapheresis Versus Phlebotomy as Maintenance Therapy in Patients With Hereditary Hemochromatosis; a Randomised, Single Blinded Sequential, Cross-over Trial

Hereditary hemochromatosis (HH) is a genetic disorder of iron metabolism, resulting in excessive iron overload. Phlebotomy is currently the standard therapy. More recently Therapeutic Erythrocytapheresis (TE) has become a new therapeutic modality, which potentially offers a more efficient method to remove iron overload with fewer procedures.In the proposed clinical trial the investigators will examine whether TE can keep the ferritin levels in patients requiring maintenance therapy below 50 microg/L, with minimally half the number of treatment procedures when compared to current standard therapy by P.
