Abstract

Objective: To explore the effects of azithromycinon in treatment of chronic obstructive pulmonary disease (COPD) in patients with acute exacerbation (AE) of chronic bronchitis (CB) in the stable phase.

Methods: Totally, 60 COPD patients with AE of CB were divided into control group (CG, 30 cases) and experimental group (EG, 30 cases) using the random number residue method. The CG was administered 250 mg salmeterol-fluticasone powder inhalation twice a day combined with 18 µg tiotropium bromide inhalation once a day. The EG was treated with 250 mg azithromycin tablets once a day in addition to the treatment of the CG. We compared the clinical effect, pulmonary function, and fractional exhaled nitric oxide index between two groups after treated for three-months.

Results: Compared with the CG, the EG showed a better clinical effect with a total effective rate at 86.67% after treatment (P<0.05). The EG exhibited better FEV1 and FEV1% than the CG (P<0.05). We also observed the difference between clinically FeNO-invalid patients before and after treatment was significant (P<0.05). After treatment, this difference among groups was statistically significant (P<0.05).

Conclusions: Azithromycin combined with salmeterol-fluticasone powder inhalation and tiotropium bromide inhalation have good effects for treating COPD patients with AE of CB in the stable stage and can improve the pulmonary function. When COPD with AE of CB was exacerbated, the FeNO index increased significantly, indicating a potential increase in the mucosal inflammatory cells and eosinophils of the airway.

Keywords: Azithromycin; chronic bronchitis; chronic obstructive pulmonary disease; fractional exhaled nitric oxide.
