Abstract

Background: Although chronic obstructive pulmonary disease (COPD) is traditionally associated with polycythemia, its systemic inflammatory components can interfere with erythropoietin and result in anemia of chronic disease. We assessed the frequency of anemia and its relation to serum erythropoietin (EPO) levels and severity of the disease in a group of COPD patients. Materials and Methods: Eighty patients with the mean age of 66.48 ± 11.55 years and mean forced expiratory volume in first second (FEV1) of 45.14 ± 16.88 % predicted were enrolled in this study. Severity of the disease was defined according to the global initiative for chronic obstructive lung disease (GOLD) guidelines. Hemoglobin and erythropoietin levels were assessed in all patients. Results: Anemia of chronic disease was present in 13 of 80 patients (16%). The mean serum levels of EPO were 59 ± 203 (SD) µ/l and 70.3 ± 255 (SD) µ/l in anemic and nonanemic COPD patients, respectively. There was no significant difference between the two groups (p=0.13). A significant correlation was seen between hemoglobin and serum EPO in all COPD and nonanemic patients (r = - 0.86, p
