Prevalence and Impact of Recurrent Rejection on Pediatric Heart Transplant Recipients: A PHTS Multi-Institutional Analysis.

Background: Studies evaluating the prevalence and impact of recurrent rejection (RR) in pediatric heart transplant (HT) are sparse.

Objectives: The purpose of this study was to describe prevalence and impact of RR on cardiac allograft vasculopathy (CAV) and graft loss after pediatric HT.

Methods: Data on HT from January 1, 2000, to June 30, 2020, in the Pediatric Heart Transplant Society database were included.

The complexities of decision-making associated with on-demand treatment of hereditary angioedema (HAE) attacks.

Background: Hereditary angioedema (HAE) is characterized by debilitating attacks of tissue swelling in various locations. While guidelines recommend the importance of early on-demand treatment, recent data indicate that many patients delay or do not treat their attacks.

Objective: This survey aimed to investigate patient behavior and evaluate the key factors that drive on-demand treatment decision-making, as reported by those living with HAE.

Gaps in Care Among Uncontrolled Severe Asthma Patients in the United States.

Background: Understanding the implementation of key guideline recommendations is critical for managing severe asthma (SA) in the treatment of uncontrolled disease.

Objective: To assess specialist visits and medication escalation in US patients with SA after events indicating uncontrolled disease (EUD) and associations with health outcomes and social disparity indicators.

Methods: Patients with SA appearing in administrative claims data spanning 2015 to 2020 were indexed hierarchically on asthma-related EUD, including hospitalizations, emergency department visits with systemic corticosteroid treatment, or outpatient visits with systemic corticosteroid treatment.

Incremental cost burden among patients with severe uncontrolled asthma in the United States.

The economic burden of severe asthma and severe uncontrolled asthma (SUA) is significant. Updated assessments of health care resource utilization (HCRU) and cost are needed given the increase in treatment options and updates to guidelines in recent years. To describe all-cause and asthma-related HCRU and costs among patients with SUA vs patients with nonsevere asthma in the United States using real-world data.
