In a new study, researchers provide recommendations for when to consider a diagnosis of hereditary angioedema (HAE) for patients who come to the  emergency room with swelling. The study, “Development of the Hereditary Angioedema Rapid Triage (HAE-RT) Tool,” was published in The Journal of Allergy…

Haegarda, a concentrated form of C1 inhibitor (C1-INH), is safe and effectively helps to prevent hereditary angioedema attacks in the long-term, allowing patients to become free of disease symptoms, That is the finding of a Phase 3 extension study, “Long-term outcomes with subcutaneous C1-inhibitor replacement therapy for prevention…

Some mutations in the SERPING1 gene that cause hereditary angioedema (HAE) result in an abnormal form of the C1 inhibitor (C1-INH) that binds to and traps healthy C1-INH in cells, severely reducing the amount of protein available to prevent HAE attacks, a study shows. The study, “Dominant negative SERPING1…

Physicians in Canada need better education about the multiple biological assays used to diagnose hereditary angioedema caused by C1 inhibitor deficiency (C1-INH-HAE), which will increase their confidence and access to relevant tests, a study shows. The study, “The diagnosis of hereditary angioedema with C1 inhibitor deficiency: a survey…
