title: Once-weekly epoetin alfa dosing is as effective as three times-weekly dosing in increasing hemoglobin levels and is associated with improved quality of life in anemic HIV-infected patients.
abstract: BACKGROUND
  Anemia is prevalent in HIV-positive patients despite lower doses of zidovudine used in highly active antiretroviral therapy. Previously, epoetin alfa has been administered 3 times weekly (TIW). We compared the hematologic and quality of life (QOL) effects and tolerability of the more convenient once-weekly (QW) regimen with TIW epoetin alfa in anemic HIV-positive patients.
  
  
  METHODS
  Two hundred eighty-five anemic (hemoglobin [Hb] <12 g/dL) HIV-positive adults receiving stable antiretroviral therapy were enrolled in this 16-week, randomized, multicenter study. Enrolled patients were randomized to receive epoetin alfa doses of 40,000 to 60,000 U QW or 100 to 300 U/kg TIW.
  
  
  RESULTS
  Two hundred seventy-two patients were evaluable for efficacy. Both epoetin alfa dosing schedules produced significant Hb level increases by week 2 (mean Hb increase of 1.3 g/dL [QW] and 1.0 g/dL [TIW]; P < 0.0001) that continued to increase until week 8 and were maintained until study completion, with no significant difference between treatment groups at final Hb measurement (mean Hb increase of 2.9 g/dL [QW] and 2.5 g/dL [TIW]). All QOL parameters improved significantly (P < 0.05) from baseline by week 8 in both groups, with no significant differences between groups at week 16. Both dosing schedules were well tolerated.
  
  
  CONCLUSIONS
  QW dosing of epoetin alfa is as effective as TIW dosing in increasing Hb levels, which was associated with improved QOL in anemic HIV-positive patients. QW dosing should also offer added convenience for patients and caregivers.
