Management of hereditary angioedema attacks by patients on long-term prophylaxis versus on-demand therapy only.

Despite the use of long-term prophylaxis (LTP) for hereditary angioedema (HAE), the risk of having an attack remains and patients with HAE and on LTP may still experience attacks that can be life threatening. However, the behavioral patterns and perspectives surrounding HAE attack management by patients on LTP are not fully understood. This survey aimed to better understand and compare the behavioral patterns and perspectives, including attitudes and perceptions associated with on-demand treatment among patients on LTP versus those using on-demand therapy only.

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.

Baseline FeNO Independently Predicts the Dupilumab Response in Patients With Moderate-to-Severe Asthma.

Background: FeNO may have a role as both a prognostic and predictive biomarker in combination with eosinophils for assessing responsiveness to some biological therapies.

Objective: We evaluated the value of baseline FeNO, adjusted for baseline blood eosinophil levels and other clinical characteristics, as an independent predictor of treatment response to dupilumab in patients with uncontrolled moderate-to-severe asthma.

Methods: We performed a post hoc analysis of LIBERTY ASTHMA QUEST (NCT02414854), a phase 3, double-blind study in patients aged 12 years and older with uncontrolled moderate-to-severe asthma, who received dupilumab 200 or 300 mg, or placebo every 2 weeks up to 52 weeks.

A novel liposome-based therapy to reduce complement-mediated injury in revascularized tissues.

Background: Ischemia/reperfusion (IR) injury is an unavoidable consequence of tissue transplantation or replantation that often leads to inflammation and cell death. Excessive complement activation following IR induces endothelial cell injury, altering vascular and endothelial barrier function causing tissue dysfunction. To mitigate the IR response, various systemic anti-complement therapies have been tried.

Cell membrane modification for rapid display of bi-functional peptides: a novel approach to reduce complement activation.

Ischemia and reperfusion of organs is an unavoidable consequence of transplantation. Inflammatory events associated with reperfusion injury are in part attributed to excessive complement activation. Systemic administration of complement inhibitors reduces reperfusion injury but leaves patients vulnerable to infection.
