Treating anemia with erythropoietin (EPO) to hemoglobin (Hb) endpoints >11 g/dL may increase risk of serious adverse cardiovascular events.
We used medical records data (1996-2003 from the Adolescent Spectrum of HIV Disease Project [ASD] and 1996-2006 from the HIV Outpatient Study [HOPS]) to describe EPO prescription patterns for mildly, moderately, or severely anemic HIV-infected patients. We calculated proportions prescribed EPO and treated to Hb>12 g/dL, and tested for trends over time. We calculated median hemoglobin at first EPO prescription, and described temporal changes using linear regression.
Among 37,395 patients in ASD and 7,005 patients in HOPS, EPO prescription increased over time for moderately anemic patients; for patients with severe anemia, EPO prescription increased only among ASD patients. Hb at EPO prescription decreased over time in ASD patients (median=8.5 g/dL), but not in HOPS patients (median 9.5 g/dL). Percentage of EPO-treated patients with post-treatment Hb>12 g/dL was 18.3% in ASD and stable, and was 56.7% in HOPS and increased over time (p = 0.03).
Through 2006, EPO prescription increased over time for patients with moderate or severe anemia. Many patients treated with EPO had post-treatment Hb>12 g/dL. Based on 2011 FDA recommendations, changes in previous prescription practices will be needed.
