epoetin-alfa and Acquired-Immunodeficiency-Syndrome

Anemia is common in patients infected with the human immunodeficiency virus (HIV). The etiology is often multifactorial and may include the HIV infection itself, opportunistic infections, cancer, medications (particularly zidovudine and sulfa-containing drugs), or anemia of chronic disease. Epoetin alfa therapy may play a supportive role in some HIV-infected patients by increasing hemoglobin, decreasing fatigue, and reducing the need for exposure to red blood cell transfusions. A large, placebo-controlled trial in the United States for anemic patients with the acquired immunodeficiency syndrome taking zidovudine demonstrated a statistically significant improvement in hematocrit in patients treated with epoetin alfa compared with placebo. Transfusion requirements decreased in epoetin alfa-treated patients over a 3-month period compared with placebo with a trend toward improvement in quality of life. Epoetin alfa was effective, however, only in patients whose pretreatment erythropoietin levels were less than 500 mU/mL. These advantages of epoetin alfa treatment may become especially important as HIV becomes more of a chronic disease, with the concern that red blood cell transfusion may accelerate progression of HIV.
