Abstract

Anemia occurs commonly in COPD and is associated with a poor prognosis. The role of comorbidities in this is suspected but poorly characterized and the economic implications of anemia combined with COPD in France have not been studied. The healthcare resource utilization and cost impact of anemia remain to be investigated. One hundred and fifty-one COPD patients attending a pulmonology outpatient department during a 6 months period were retrospectively selected if they had undergone a pulmonary function test, a blood gas analysis or a blood count. The Charlson comorbidity index, resource utilization and economic data from the year before the diagnosis of anemia were compared between anemic and non-anemic patients as well as 3-year survival analysis. The prevalence of anemia was 18.5% and was not influenced by GOLD stage. The identification of anemia was similar from blood gas results and full blood count analysis. Comorbidities - mainly cardiovascular - were found in 86% of the anemic patients. The Charlson index was 5.4±2 in the anemic group compared to 4.1±1.5 in the non-anemic group (P<0.01). The Charlson index was the only predictive factor of anemia using logistic regression analysis. The 3-year mortality was 36% in the an...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
