    Abstract:
    Anemia, a common hematological abnormality in HIV, contributes to decreased quality of life (QOL). This study assessed once-every-2-week epoetin alfa on maintaining QOL and hemoglobin (Hb) in anemic HIV-infected patients in a 24-week, open-label, multicenter study. HIV-infected patients (Hb < or =12 g/dl) received epoetin alfa 40,000 units subcutaneously once weekly, until reaching Hb > or =13 g/dl. Patients then entered a maintenance phase (MP), in which epoetin alfa was administered every other week or at longer intervals. The trial objectives were to determine if QOL, as measured by the Medical Outcomes Study-HIV (MOS-HIV) general health perceptions (GHP) domain and Hb, was maintained. Safety was also assessed. A total of 292 patients were enrolled (72% on HAART). Mean baseline laboratory values were Hb = 10.8 g/dl, CD4(+) count = 280 cells/microl, and HIV RNA = 51,867 copies/ml. In all, 81% of patients reached Hb > or =13 g/dl and 92% reached Hb > or =12 g/dl. QOL was maintained from the beginning (GHP = 44.2 points) to the end of MP (GHP = 43.4 points) with every other week or longer dosing. Mean Hb at the beginning of MP was 13.4 +/- 0.5 g/dl and was 12.8 +/- 1.4 g/dl at study end. Epoetin alfa was well tolerated; adverse events were consistent with those reported in previous studies of epoetin alfa in HIV-infected patients. Although the clinical approach tested in this study is not consistent with current prescribing recommendations, the results confirm the efficacy of prolonged dosing intervals (every 2-4 weeks) in maintaining optimal Hb levels and QOL in anemic HIV-infected patients.
