Multicenter Study Observational Study
Effectiveness and safety of omalizumab in severe, persistent IgE-mediated asthma in pediatric and adult patients: a real-world observational study in Egyptian population.
Objective: Real-world studies on the effectiveness of omalizumab in Egyptian population with asthma are limited. This study aimed to evaluate the real-world effectiveness and safety of omalizumab as an add-on treatment in pediatric and adult patients with severe, persistent allergic asthma in Egypt. Methods: The primary endpoint of this 16-week, prospective, open-label, multicenter, non-interventional study was the reduction in oral corticosteroid (OCS) dose. ⋯ No new safety signals were observed in the safety analysis of omalizumab as add-on treatment. Conclusions: Outcomes of this real-world study were consistent with previous effectiveness and safety studies of omalizumab. Omalizumab was effective and well tolerated for the management of severe, persistent IgE-mediated asthma in pediatric and adult patients in Egypt.

Comparative Study
Cost-effectiveness of omalizumab for the treatment of inadequately controlled severe allergic asthma in Chinese children.
Objective: The addition of omalizumab to standard therapy has proven to be efficacious in children with severe allergic asthma. The goal of this study was to assess the cost-effectiveness of adding omalizumab to standard treatment for asthma in Chinese pediatric patients. Methods: A Markov model was constructed to project the health and economic outcomes in pediatric patients with severe allergic asthma. ⋯ Results: For the base-case analysis, the addition of omalizumab to standard therapy yielded an incremental cost of $49,047 for 0.232 incremental QALY, led to an incremental cost-effectiveness ratio of $211,217/QALY. Sensitivity analyses were robust for these results. Conclusions: This study found that the addition of omalizumab is not a cost-effective strategy compared with standard therapy for children with severe allergic asthma in China due to its high cost.

Objective: Many patients with a chief complaint of chest tightness are examined in medical facilities, and a lack of diagnosis is not uncommon. We have reported that these patients often include those with chest tightness relieved with bronchodilator use (CTRB) and those with chest tightness relieved with the use of asthma drugs except bronchodilators (CTRAEB). The purpose of this study was to demonstrate the clinical characteristics of the patients with CTRAEB and compare them with data from patients with CTRB. ⋯ Conclusions: We hypothesized that the clinical condition of patients with CTRAEB involves chest tightness arising from inflammation alone, and this chest tightness is mostly associated with airway T cells, without constriction of the airways. There is little to distinguish CTRAEB from CTRB aside from the response to bronchodilator treatment. This clinical trial is registered at www.umin.ac.jp (UMIN13994, 13998, and 16741).

Objective: Evidence suggests using metered dose inhaler (MDI) to treat acute asthma in the Emergency Department reduces length of stay, though methods of implementation are lacking. We modified a treatment pathway to recommend use of MDI for mild-moderate asthma in a pediatric ED. Methods: A baseline review assessed discharged patients >2 years with an asthma diagnosis and non-emergent Emergency Severity Index triage assessment (3/4). ⋯ We identified special cause variation for reduction in CA use from 43% to 25%; Revisit rate and length of stay for higher-acuity patients did not change; overall asthma admissions decreased by 8%. Changes were sustained for 18 months. Conclusion: A change to an ED asthma pathway recommending MDI for mild-moderate asthma led to a rapid and sustained decrease in continuous albuterol use, length of stay, and admission rate.

Randomized Controlled Trial Comparative Study
Effectiveness of fluticasone furoate/vilanterol versus fluticasone propionate/salmeterol on asthma control in the Salford Lung Study.
The Asthma Salford Lung Study demonstrated the effectiveness of initiating once-daily fluticasone furoate/vilanterol (FF/VI) versus continuing usual care in asthma patients in UK primary care [ 1 ]. Here, we report a secondary analysis in a subset of patients with fluticasone propionate/salmeterol (FP/Salm) as their baseline intended maintenance therapy, to evaluate the relative effectiveness of initiating FF/VI versus continuing FP/Salm. ⋯ For patients in primary care, initiating FF/VI was significantly better than continuing with FP/Salm for improving asthma control and quality of life, and reducing asthma exacerbations, with no notable difference in SAEs. ClinicalTrials.gov: NCT01706198.
