Epoetin alfa once weekly improves anemia in HIV/hepatitis C virus-coinfected patients treated with interferon/ribavirin: a randomized controlled trial. 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.
nan 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.
                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.
                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.
                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.
This updated Cochrane review provides evidence that rHuEPO compared with placebo does not reduce mortality, does not reduce transfusion requirements, did not increase hemoglobin levels, and did not improve quality of life in HIV-infected patients with anemia. The results are based on six RCTs with high risk of bias. Therefore prescription of this intervention for treating anemia in patients with AIDS is not justified, unless new evidence from a large high quality trial alters this conclusion.
