Acute exacerbation of chronic obstructive pulmonary disease: what the trials found

Management of COPD involves various pharmacological and rehabilitative approaches. Clinical trials evaluated the impact of Roflumilast on exacerbation rates, finding no statistically significant difference in the rate of moderate or severe exacerbations per patient per year (p=0.1634) or those requiring hospitalization/death (p=0.6354). Additionally, there was no significant difference in the rate of exacerbations treated with antibiotics (p=0.0884).

Pharmacological interventions include corticosteroids and bronchodilators; for example, Prednisone was evaluated regarding treatment failure at 90 days 3, and Theophylline ER was associated with changes in St. George Respiratory Questionnaire (SGRQ) scores 4. Antibiotic therapy comparisons between Levofloxacin and Prulifloxacin showed specific counts of therapeutic success at the end of a 10-day cycle 2.

Pulmonary rehabilitation programs, including home-based models, have been evaluated for their impact on quality of life and physical symptoms. Home-based pulmonary rehabilitation was associated with changes in EQ-5D scores 6 and significant improvements in emotional symptoms as measured by the Chronic Respiratory Questionnaire (CRQ) 11.

Recent results — preliminary, needs further review

  • MSTT1041A showed no statistically significant difference in the number of moderate to severe exacerbations compared to control 5.
  • Telehealth pulmonary rehabilitation was associated with a significant reduction in the composite of COPD hospital readmission/death within 6 months of discharge (p=<.05) 8.
  • Telemonitoring and telephone control were associated with statistically significant results regarding time until first exacerbation (p=<0.05) 9.
  • Formoterol was evaluated for its effect on Peak FEV1 and FVC following inhalation 12.

For the clinician treating this condition

  • Roflumilast did not demonstrate a statistically significant reduction in the frequency of moderate to severe exacerbations or those requiring hospitalization.
  • Home-based pulmonary rehabilitation is associated with improvements in emotional symptoms and changes in quality of life scores (EQ-5D).
  • Telehealth and telemonitoring interventions show potential for reducing hospital readmissions and influencing time to first exacerbation.
