Lipid profile patterns in chronic obstructive pulmonary disease and its correlation with the severity of disease

This cross-sectional study was conducted to determine the serum lipid profiles in chronic obstructive pulmonary disease (COPD) patients and its correlation with the severity of COPD in the Department of Respiratory Medicine at Bangabandhu Sheikh Mujib Medical University. A total of 100 spirometric-confirmed cases of COPD were included. Fasting blood samples for lipid profiles were collected. To identify the association between severity of COPD with lipid profiles Pearson’s correlation was used. Further multiple linear regression was done to identify the relation. The mean (standard deviation) age of the patients was 59.0 (10.7)years. The ratio of males and females was 19:1. The mean forced expiratory volume (liters) in 1 second (FEV1) was 55.1 (18.1). Most of the patients had stage II (48%) and stage III (36%) airflow obstruction. Plasma level of total cholesterol and triglyceride tend to increase, statistically non-significant, with stages of COPD. However, the association of plasma lipids becomes statistically significant with FEV1 when the effects of age, BMI, pack-year smoking, duration of illness are accounted in multiple linear regression analysis.
