Anemia is common in HIV infection, but the pathophysiology is poorly understood. Bone marrow analysis in 329 severely anemic (hemoglobin <5 g/dl) Malawian children with (n = 40) and without (n = 289) HIV infection showed that HIV-infected children had fewer CD34(+) hematopoietic progenitors (median 10 vs. 15‰, P = 0.04) and erythroid progenitors (2.2 vs. 3.4‰, P = 0.05), but there were no differences in erythrocyte viability and maturation in later stages of erythropoiesis. Despite an HIV-associated reduction in early red cell precursors, subsequent erythropoiesis appears to proceed similarly in HIV-infected and HIV-uninfected children with severe anemia.
