Risk of adverse reactions associated with inhaled corticosteroids for chronic obstructive pulmonary disease: A meta-analysis.

BACKGROUND

In the majority of current therapeutic regimens for chronic obstructive pulmonary disease (COPD), bronchodilators are coupled with inhaled corticosteroids (ICS) to lower the inflammatory response and improve symptoms. This study aims to evaluate the safety of ICS in the treatment of COPD.

METHODS

Randomized controlled trials related to ICS for COPD that were eligible up to 1 June 2023 were searched in PubMed, EMBASE, and Cochrane. We searched and screened eligible studies for the occurrence of total adverse events, cardiovascular events, upper respiratory tract infections (URTI), pneumonia, oral Candida infections, and musculoskeletal disorders, and finally analyzed them by Review Manager 5.4.1.

RESULTS

The results showed that ICS increased the incidence of adverse reactions in COPD patients (RR = 1.06, 95% CI: 1.03-1.10, P = .0004); ICS treatment did not increase the risk of cardiovascular events in COPD patients (RR = 0.95, 95% CI: 0.88-1.02, P = .14); ICS increased the incidence of URTI in COPD patients (RR = 1.29, 95% CI: 1.02-1.62, P = .03); ICS increased the incidence of pneumonia in patients with COPD (RR = 2.09, 95% CI: 1.63-2.69, P < .00001); ICS treatment significantly increased the incidence of oral Candida in patients with COPD (RR = 2.96, 95% CI: 1.99-4.41, P < .00001); ICS increased the incidence of musculoskeletal disorders in patients with COPD (RR = 2.87, 95% CI: 1.51-5.45, P = .001).

CONCLUSION

ICS does not increase the risk of cardiovascular events in patients with COPD, but it does increase the risk of URTI, pneumonia, oral Candida infections, and musculoskeletal disorders in patients with COPD.
