Abstract
Introduction
While selected clinical and laboratory findings are taken into account to find the best therapeutic strategies for chronic obstructive pulmonary disease (COPD), it is unknown whether the circadian rhythm of respiratory symptoms, a distinctive feature of COPD, affects the prescription pattern of pharmacological therapy. The main aim of this study was to verify whether the circadian rhythm of symptoms correlates with bronchodilating therapy prescribed to COPD patients as per clinical practice. A secondary objective was to assess the relationship between Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage and circadian rhythm of symptoms and health status.
Methods
Five hundred sixty-six COPD patients were enrolled in the Italian multicenter STORICO study. Patients underwent a multidimensional assessment, and correlates of prescribed therapy were assessed through a multivariate multilevel model.
Results
As expected, patients in GOLD D stage were more likely to receive triple inhaled therapy than GOLD A–C patients, but the circadian rhythm of symptoms, assessed by the nighttime, morning, and daytime symptoms of the COPD questionnaire, was unrelated to the prescription pattern. The multivariate model showed that emphysematous (EM) patients had a 50% increased risk compared with patients affected by chronic bronchitis (CB) of being prescribed long-acting β2-agonists (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combination (FDC) instead of triple therapy [relative risk (RR) EM versus CB 1.50, 95% CI 1.11, 2.03]. Symptoms, mainly in the early morning and daytime, were highly prevalent, even in GOLD B stage (76%).
Conclusion
Even if we cannot infer about causality of the symptoms–therapy relationship, based on the structured recording of circadian symptoms clearly shows that symptoms are poorly controlled as the circadian rhythm of symptoms does not correlate with the prescription pattern, and many patients are symptomatic both at daytime and by nighttime. Thus, therapy should be better tailored to the individual needs, with special attention to control nocturnal symptoms.
