Takeaway

  • In patients with chronic obstructive pulmonary disease (COPD), composed mostly of infrequent exacerbators, discontinuation of inhaled corticosteroid (ICS) from triple therapy (TT; long-acting muscarinic antagonist [LAMA]+long-acting beta2-agonist [LABA]+ICS) was not associated with an increased risk of exacerbation.

  • However, the risk of reinitiating ICS or suffering an exacerbation was significantly increased in subgroup of patients with blood eosinophil count ≥300 cells/μL and having more oral corticosteroid (OCS) prescriptions in the year prior to ICS cessation.

Why this matters

  • Discontinuation of ICS from TT is still very infrequent in primary care.

  • Findings support the recommendations that ICS withdrawal should be considered in patients without a history of frequent exacerbations and low blood eosinophil counts.

Study design

  • This observational comparative effectiveness study included 1046 patients who withdrew ICS matched 1:4 by time on TT to 4184 patients who continued with TT over a period of 1 year of observation from the UK Optimum Patient Care Research Database (OPCRD).

  • 76.1% of patients had 0 or 1 exacerbation the previous year.

  • Primary outcome: time to first COPD exacerbation.

  • Funding: Boehringer Ingelheim.

Key results

  • After controlling for confounders, cessation of ICS was not associated with an increased risk of moderate or severe exacerbations (adjusted HR, 1.04; 95% CI, 0.94-1.15; P=.441).

  • Rates of exacerbations managed in primary care (incidence rate ratio [IRR], 1.33; 95% CI, 1.10-1.60; P=.003) or in hospital (IRR, 1.72; 95% CI, 1.03-2.86; P=.036) were significantly higher in the ICS withdrawal group.

  • The odds of successful ICS withdrawal were significantly reduced with:

    • blood eosinophil count ≥300 cells/μL (aHR, 0.50; 95% CI, 027-0.91; P=.023); and

    • frequent courses of OCS in the year prior to ICS cessation.

      • 2 prescriptions (aHR, 0.23; 95% CI, 0.11-0.44; P<.001).

      • >3 prescriptions (aHR, 0.31; 95% CI, 0.19-0.47; P<.001).

Limitations

  • Observational design.

  • Risk of bias.
