Evaluation of erythropoietin hormone in chronic obstructive pulmonary disease patients during exacerbation and after remission

EPO hormone level was significantly higher in grade (II, III) than grade (I, IV) COPD patients (p = 0.005), and also COPD with anemia was higher in stage (II, III) than stage (I, IV), EPO hormone level significantly higher in anemic than non anemic COPD patients and was significantly higher (p = 0.005) during remission than during exacerbation.
