Assessment of Real-World Escalation to Biologics in US Patients With Asthma.

Background: Previous studies indicate that suboptimal medication adherence may contribute to uncontrolled asthma. Global Initiative for Asthma (GINA) guidelines recommend treatment escalation to biologics for patients with uncontrolled asthma despite adherence to high-dose maintenance medication and who have eosinophilic/allergic biomarkers or require maintenance oral corticosteroids.

Objective: This study aimed to describe the clinical status of patients with asthma escalated to biologic therapy.

Alpha-1 Antitrypsin Deficiency-Associated Clinical Manifestations and Healthcare Resource Use in the United States.

Pulmonary events (PEs) associated with alpha-1 antitrypsin deficiency (AATD) can have a severe clinical course and increase healthcare resource use (HRU). However, AATD-associated HRU and healthcare costs have not been extensively described. This study describes and compares real-world HRU and healthcare costs among US patients with severe (requiring hospitalization after AATD-related PE) versus nonsevere AATD clinical course.
