    Abstract:
    OBJECTIVE: In 2002, many haemodialysis patients were switched from subcutaneous (s.c.) to intravenous (i.v.) administration of epoetin-alpha following reports of antibody formation and development of pure red-cell aplasia in patients treated via the s.c. route. We evaluated the possible effect of this change in the route of administration on haemoglobin (Hb) levels and epoetin-alpha requirements. MATERIAL AND METHODS: This retrospective survey involved 223 haemodialysis patients from 25 Swedish centres. Variables were recorded before and after a mean period of 213 days (range 89-297 days) after the change in the route of administration. RESULTS: The mean epoetin-alpha do had to be increased from 159+/-104 to 185+/-122 U/kg/week (p<0.0001) to maintain a constant Hb level (121+/-12 vs 120+/-11 g/l). Plasma ferritin, albumin, C-reactive protein, iron, iron transferrin saturation and body mass index remained constant. The relative increase in epoetin-alpha dose was negatively correlated with the s.c. dose prior to the switch (R=-0.3; p<0.0001), with the most pronounced dose increases occurring in patients who received a low s.c. dose. CONCLUSIONS: A switch from s.c. to i.v. administration of epoetin-alpha in haemodialysis patients was accompanied by an increase in the mean dose requirement of 15%. This increase may be less pronounced in patients receiving high s.c. doses prior to the switch.
