A randomized, single-blind study of lansoprazole for the prevention of exacerbations of chronic obstructive pulmonary disease in older patients.

Pubmed ID: 

OBJECTIVES: To investigate whether proton pump inhibitor (PPI) therapy reduces the frequency of common colds and exacerbations in patients with chronic obstructive pulmonary disease (COPD). DESIGN: Twelve-month, randomized, observer-blind, controlled trial. SETTING: A university hospital and three city hospitals in Miyagi prefecture in Japan. PARTICIPANTS: One hundred patients with COPD (mean age +/- SD 74.9 +/- 8.2) participated. They were all ex-smokers and had received conventional therapies for COPD, including smoking cessation and bronchodilators. Patients with gastroesophageal reflux disease or gastroduodenal ulcer were excluded. INTERVENTION: Patients were randomly assigned to conventional therapies (control group) or conventional therapies plus PPI (lansoprazole 15 mg/d; PPI group) and observed for 12 months. MEASUREMENTS: Frequency of common colds and COPD exacerbations. RESULTS: The number of exacerbations per person in a year in the PPI group was significantly lower than that in the control group (0.34 +/- 0.72 vs 1.18 +/- 1.40; P<.001). The adjusted odds ratio with logistic regression for having exacerbation (> or =once/year) in the PPI group compared with the control group was 0.23 (P=.004). In contrast, there was no significant difference in the numbers of common colds per person per year between the PPI group and the control group (1.22 +/- 2.09 vs 2.04 +/- 3.07; P=.12). PPI therapy significantly reduced the risk of catching frequent common colds (> or =3 times/year), the adjusted odds ratio of which was 0.28 (P=.048). CONCLUSION: In this single-blind, nonplacebo-controlled trial, lansoprazole was associated with a significant decrease in COPD exacerbations. More definitive clinical trials are warranted.
