We describe a complete cytogenetic response to interferon-alpha in a patient with chronic myelogenous leukemia undergoing chronic hemodialysis. Although IFN-alpha therapy has been applied to patients with chronic hepatitis C receiving hemodialysis, the pharmacokinetics of IFN-alpha in patients with poor renal function still remain unclear. In the present patient, the serum IFN-alpha concentration remained high even 48 hours after injection (42.9 IU/ml), and IFN-alpha was almost completely removed by hemodialysis (< 6 UI/ml). The patient was treated with IFN-alpha (3 x 10(6) IU, three times a week), and cytogenetic disappearance (0%) of the Ph-positive clone was confirmed 31 months after the start of therapy. Recombinant human erythropoietin (Epo) was used to treat anemia due to renal failure and IFN-alpha therapy. The anemia was controllable with Epo, and no adverse effect was observed.
