Anemia is the most commonly encountered hematologic abnormality in human immunodeficiency virus (HIV)-positive patients, occurring with increasing frequency as the disease progresses. Several factors play a role in the development of anemia in patients with HIV, including chronic disease, opportunistic infections, and certain nutritional deficiencies. Despite the high prevalence of anemia in this population, the symptoms of anemia are frequently overlooked, although anemia can significantly affect a patient's ability to carry on even normal activities of daily living. Therefore, approaches--including the treatment of causative infections, discontinuation of certain drugs, or use of recombinant human erythropoietin (epoetin alfa)--aimed at increasing hemoglobin levels to normal or near-normal levels would be expected to improve quality of life (QOL). The purpose of this article is to describe the effects of anemia on QOL and to provide an overview of several studies showing that QOL improves with the alleviation of anemia.
Three large observational cohort studies suggest that, after controlling for virus load and CD4 cell count, anemia is related to disease progression and survival in patients with human immunodeficiency virus (HIV) infection. Recovery from anemia has been linked to improved survival outcomes. Blood transfusion has been associated with accelerated disease progression and mortality in patients with HIV infection, and review of related literature suggests that the mechanism for negative transfusion-associated outcomes may be transfusion-related immunosuppression. Therefore, the use of transfusion should be restricted to patients with acute or severe anemia. Prescription of epoetin alfa has been associated with increased survival in an observational cohort among patients with HIV infection and anemia. In the absence of data from a clinical trial documenting the effect of treating anemia on survival, clinicians should consider non-transfusion options for management of anemia on the basis of clinical status and patient functional ability.
