Study on the factors related to pneumonia and exacerbation in patients with chronic obstructive pulmonary disease (COPD) - Study on the factors related to pneumonia and exacerbation in patients with chronic obstructive pulmonary disease (COPD)

In the exacerbation group (n=60), the values of pulmonary function test, including FVC and FEV1, and serum total protein and albumin concentrations were lower, and COPD severity rankings, and proportions of patients with severe emphysema and receiving long-term oxygen therapy were higher than those in the nonexacerbation group (n=76). In the multivariate analysis, the risk factors were hypoalbuminemia, hypoproteinemia and low FEV1.
