Swelling in the hands and feet, as well as elevated blood levels of eosinophils — a type of immune cell — led clinicians to diagnose a Japanese woman with non-episodic angioedema associated with eosinophilia (NEAE), as described in a case report. Distinguishing NEAE from similar conditions is important, the…

One person out of six treated with Ruconest (rhC1INH) for idiopathic non-histaminergic angioedema (InH-AAE) as part of an exploratory study showed a positive clinical response to the medication. The findings may mean that Ruconest is effective in a subset of InH-AAE patients, the researchers noted. The study, “…

Death due to breathing difficulties associated with hereditary angioedema (HAE) remains a concern in Brazil, highlighting that misdiagnosis and a lack of treatment access in lower-income countries may contribute to increased mortality rates, a recent study highlights. While HAE-associated deaths have declined significantly in recent years within high-income countries,…
