Anemia is common during human immunodeficiency virus (
HIV) infection and is associated with increased mortality. We conducted a study to examine the impact of
highly active antiretroviral therapy (
HAART) on
anemia in a multicenter cohort of HIV-positive women, the Human Immunodeficiency Virus Epidemiology Research (HER) Study. Among women receiving
HAART (n = 188), non-
HAART monotherapy or
combination antiretroviral therapy (ART) (n = 111), or who had no reported treatment (n = 62), the prevalence of
anemia (
hemoglobin, <120 g/L) at baseline was 38.3, 36.9, and 43.6%, respectively (p = 0.58) and at 1-year follow-up was 26.1%, 36.9%, 45.2%, respectively (p = 0.01); mean
hemoglobin at baseline was 125 +/- 16, 122 +/- 16, and 122 +/- 18 g/L, respectively (p = 0.29) and at 1-year follow-up was 128 +/- 14, 123 +/- 16, and 119 +/- 20 g/L, respectively (p < 0.0001). Adjusted linear regression models showed that
HAART was associated with an increase of
hemoglobin of 0.20 g/L per month (p = 0.007). After 1 year of treatment,
HAART was associated with a 32% reduction in
anemia among HIV-infected women (p = 0.01), whereas there was no significant change in the prevalence of
anemia among those on non-
HAART ART or those who had no reported treatment.
HAART is associated with a large reduction in
anemia among HIV-infected women.
