Background & Objectives:
Anemia is a common co-existing entity in numerous chronic diseases like COPD. The recent studies have suggested that the prevalence of anemia in patients with COPD has a frequency ranging from 7.5% to 34%. Anemia negatively affects COPD as it is associated with greater healthcare resource utilization, impaired quality of life, and decreased survival. This study was undertaken to find out the prevalence and clinical impact of Anaemia of Chronic Disease in COPD patients.
Methods: This study was conducted on all consecutive stable COPD patients and related data was recorded. The St George Respiratory Questionnaire (SGRQ) and the BODE index (Body Mass Index, FEV1, Dyspnoea, Exercise Capacity) was used to analyze the Health Related Quality of Life and the morbidity level of included patients.
Results: Thirty two COPD patients had anaemia. The analysis showed significantly higher symptom score (p=0.04), lower BMI (p=0.03), poor dyspnoea score (p=0.05) and significantly lower six minute walk distance (p=0.05) in the anaemic COPD patients.
Conclusions: The prevalence of anaemia in stable COPD patients is 32%, which is significantly associated with low BMI, worsening dyspnoea and reduced exercise capacity. These factors can affect the quality of life of COPD patients thus, leading to increased morbidity. Hence, treating anaemia should hold a special place in treatment regime for COPD.
