Journal of Nephrology (Milano. 1992). - 1121-8428 .- 1724-6059. ; 17:4, s. 525-530 Journal article (other academic/artistic)abstract BACKGROUND: The optimal subcutaneous (SC) epoetin alfa strategy is unestablished. The individual variability in dose requirements needs consideration. In this study, prolonged intervals were assessed in relation to varying dose requirements. METHODS: The study included 153 hemodialysis (HD) patients on stable SC epoetin alfa. Based on dose requirements, the patients received either 4,000 U (group I, n=51) or 10,000 U (group II, n=102) as whole 1 mL vials at prolonged intervals. The study comprised three 8-week periods: an initial period maintaining the basal regimens, an adjustment period where the intervals were prolonged, and a maintenance period. Alterations in hemoglobin (Hb), weekly doses and intervals in each group were compared. RESULTS: One hundred and thirty-seven patients completed the study (48 in group I and 89 in group II). In group I, the mean interval was prolonged from 5.4 +/- 1.9 to 7.8 +/- 3.1 days (p=0,01) with stable Hb and EPO doses. In group II, prolonged intervals were associated with a reduction in mean Hb below target level and a significant increase in EPO doses (p=0,002). Iron deficiency and inflammation could explain the poor response in approximately one-third of the patients. CONCLUSIONS: In HD patients, the optimal injection frequency should be individually adjusted. Prolonged intervals can be applied to patients with low-dose requirements. Observing iron status and inflammation is necessary for optimal response.
