A Real World Study to Assess the Effectiveness of Switching to Once Daily Closed Triple Therapy from Mono/Dual Combination or Open Triple Therapy in Patients with Chronic Obstructive Pulmonary Disease.
Abstract
This real world study evaluated the effectiveness of switching to closed triple therapy from mono/dual combination or open triple therapy in patients with chronic obstructive pulmonary disease (COPD). We conducted this retrospective study at a single medical center from December 2014 to September 2020. Patients with COPD who were stepped up to triple therapy were enrolled. We analyzed the duration from initial COPD management to open or closed triple therapy and identified the clinical predictors of the patients who needed triple therapy early. We also evaluated the effectiveness of triple therapy after switching from initial management, and closed triple therapy after switching from open triple therapy. A total 115 COPD patients who were stepped up to triple therapy from initial treatment were analyzed. The duration from initial treatment to triple therapy was 22.4 months. The baseline peripheral blood eosinophil counts of the patients who switched to triple therapy early (n=63, less than 22 months) and those who switched to triple therapy later (n=52, more than 22 months) were similar (489.6 vs 434.5 cells/uL; p=0.589). After univariate and multivariate analysis, the patients who were older had more acute exacerbations (AEs) ...Continue Reading

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
