Abstract
Objective: To investigate the prophylactic effect of BCG polysaccharides nucleic acid (BCG-PSN) on patients with chronic obstructive pulmonary disease and inquire about the mechanism thereof.
Methods: Sixty patients with chronic obstructive pulmonary disease were divided into two groups. In the treatment group, 36 patients received BCG-PSN 0.5 mg intramuscular injection, quaque die alterna, for 18 times. All patients revisited the hospital every 2 weeks and were followed up for 6 months. The number and days of patients with acute attack in 3 and 6 months were assessed. In the treatment group, the blood samples were collected before treatment and 3 and 6 months after treatment for the measurement of the blood IgA, IgG, IgM, CD3, CD4 and CD8.
Results: The number and days of patients with acute attack in the treatment group were significantly lower than those in the control group. After the treatment by BCG-PSN, blood CD4 and CD4/CD8 were significantly increased.
Conclusion: BCG-PSN increases the patient's cellular immunocompetence and thus serves as a good protection against the acute attack of chronic obstructive pulmonary disease.
