Erythropoietin synthesis is traditionally considered to be decreased in anemia of chronic disease. The purpose of our research was the evaluation of erythropoietin level in HIV-positive patients with anemia of chronic disease. 98 patients were included (63 — with anemia of chronic disease and 35 — with iron-deficiency anemia). The levels of erythropoietin, proinflammatory cytokines and acute-phase proteins were detected. Strong negative correlations of hemoglobin and erythropoietin were found in both groups: r=-0,8; p=0,00005 in group with iron-deficiency anemia and r=-0,5; p=0,0003 in group with anemia of chronic disease. High levels of proinflammatory cytokines (tumor-necrosis factor-α and interleukin-1β) were presented in both groups, representing the state of chronic immune activation in HIV+patients. Nevertheless higher levels of acute-phase proteins (C-reactive protein and ferritin) and lower level of negative acute-phase protein — transferrin — were detected in group with anemia of chronic disease. Correlations of erythropoietin level with levels of cytokines and acute phase proteins were not found.

Conclusion: adequate response of erythropoietin-producing cells to decrease of hemoglobin level is presented in anemia of chronic disease in HIV-positive patients.

Key words: HIV-infection, anemia, erythropoietin, inflammation.
