Hemosiderosis in a dialysis patient: treatment with hemofiltration and deferoxamine chelation therapy
Although the highly permeable membranes utilized in hemofiltration are theoretically more permeable to deferoxamine-chelated iron than the standard cuprophan membranes used in conventional hemodialysis, no clinical data support this contention. Ours are the first published results of a preliminary short-term trial of combined therapy with deferoxamine and hemofiltration in a dialysis patient with hemosiderosis. An average of 15.3 mg of iron was mobilized with a 19.5-liter exchange over only 4 1/2 hours of postdilution hemofiltration. This compares favorable with previous reports in which 8 to 12 hours of dialysis were performed with Kiil dialyzers, and also with the 24-hour urinary excretion of chelated iron in iron-overloaded patients with normal renal function. We conclude that combined therapy with deferoxamine and hemofiltration offers promises as an effective means of iron mobilization in dialysis patients with hemosiderosis.
