We read with interest the results by Rahimi-Rad MH et al. (1) suggesting that anemia is a predictor of mortality in chronic obstructive pulmonary disease (COPD). There is indeed increasingexpanding data highlighting the significant burden of anemia in patients with COPD. In our cohort, in Respiratory Department of State University of Medicine and Pharmacy “Nicolae Testemitanu”, Chisinau, Moldova, we found that anemia is also an independent risk factor for worsening dyspnea, reduced functional capacity and more comorbidities in COPD patients.
