- Background and aims Little information is available on real-life occurrence of oral thrush in COPD patients treated with ICS. We investigated oral thrush incidence in COPD patients prescribed FDC ICS/LABA therapies and assessed whether it is modulated by the ICS type, dose, and delivery device. Methods We conducted a historical, observational, matched cohort study (one baseline year before and one outcome year after initiation of therapy) using data from the UK Optimum Patient Care Research Database. We assessed oral thrush incidence in patients initiating long-acting bronchodilators or FDC ICS/LABA therapy. We then compared different combination therapies (budesonide/formoterol fumarate dihydrate [BUD/FOR] and fluticasone propionate/salmeterol xinafoate [FP/SAL]) and devices (DPI and pMDI). Results Patients prescribed FDC ICS/LABA had significantly greater odds of experiencing oral thrush than those prescribed long-acting bronchodilators alone (adjusted OR 2.18 [95% CI 1.84–2.59]). Significantly fewer patients prescribed BUD/FOR DPI developed oral thrush compared with FP/SAL DPI (OR 0.77 [0.63–0.94]) when allowing for differences in prescribed doses between the drugs. A significantly smaller proportion of patients developed oral thrush in the FP/SAL pMDI arm than in the FP/SAL DPI arm (OR 0.67 [0.55–0.82]). Additionally, in the FP/SAL cohort (both DPI and pMDI), increased risk of oral thrush was significantly associated with high ICS daily dose (OR 1.97 [1.22–3.17] vs low daily dose). Conclusions ICS use increases oral thrush incidence in COPD and this effect is dose-dependent for FP/SAL therapies. Of the therapies assessed, FP/SAL pMDI and BUD/FOR DPI may be more protective against oral thrush.

- Background: Patients with asthma and elevated blood eosinophils are at increased risk of severe exacerbations. Management of these patients should consider nonadherence to inhaled corticosteroid (ICS) therapy as a factor for increased exacerbation risk. Objective: The objective of this study was to investigate whether poor adherence to ICS therapy explains the occurrence of asthma exacerbations in patients with elevated blood eosinophil levels. Methods: This historical cohort study identified patients within the Optimum Patient Care Research Database, aged 18 years or more, at Global Initiative for Asthma step 3 or 4, with 2 or more ICS prescriptions during the year before the clinical review. Patient characteristics and adherence (based on prescription refills and patient self-report) for ICS therapy were analyzed for those with elevated (>400 cells/μL) or normal (≤400 cells/μL) blood eosinophils. Results: We studied 7195 patients (66% female, mean age 60 years) with median eosinophil count of 200 cells/μL and found 81% to be not fully adherent to ICS therapy. A total of 1031 patients (14%) had elevated blood eosinophil counts (58% female, mean age 60 years), 83% of whom were not fully adherent to ICS. An increased proportion of adherent patients in the elevated blood eosinophil group had 2 or more exacerbations (14.0% vs 7.2%; P =.003) and uncontrolled asthma (73% vs 60.8%; P =.004) as compared with non–fully adherent patients. Conclusions: Approximately 1 in 7 patients had elevated eosinophils. Adherence to ICS therapy was not associated with decreased exacerbations for these patients. Additional therapy should be considered for these patients, such as biologics, which have been previously shown to improve control in severe uncontrolled eosinophilic asthma.
