A woman still doesn’t have a definitive answer as to the underlying cause of her angioedema after more than a decade of recurrent facial swelling, underscoring the difficulties in diagnosing the condition. “This case report demonstrates the challenge of the differential diagnosis of angioedema without wheals,” the researchers wrote…

An elderly woman developed angioedema about 20 days after being given ticagrelor, a medicine that prevents blood clots from forming and is commonly used to lower the risk of a heart attack or stroke. “Given the uncommon number of cases reported involving ticagrelor-induced angioedema and the even rarer, delayed…

Most hereditary angioedema (HAE) patients in a Phase 1/2 clinical trial have gone months without a swelling attack following a single infusion of the experimental gene-editing therapy NTLA-2002. The remaining patients haven’t yet reached the pre-specified 16-week follow-up period for their attack rates to be analyzed, but their comparable…

Short-term preventive treatment with Berinert, a plasma-derived form of the C1 inhibitor protein, protects people with hereditary and acquired C1-inhibitor (C1-INH) deficiency from angioedema attacks after dental procedures, according to a recent study. The study, “Short-term prophylaxis in patients with angioedema due to C1-inhibitor…

Researchers have identified risk factors that may predispose children to more severe initial angioedema attacks — factors such as male gender, preschool age, presence of fever or hives, and a history of allergies. Epinephrine treatment and receiving care in a pediatric observation unit, on the other hand, were factors that…

Takhzyro (lanadelumab), a kallikrein inhibitor by Shire, has been approved in Europe for the routine prevention of hereditary angioedema (HAE) attacks in patients ages 12 and older, making it the first antibody available in the EU for this indication. The European Commission’s decision comes shortly after the Committee for Medicinal Products…

Patients in Germany treat acute hereditary angioedema attacks with Firazyr (icatibant) earlier and have fewer severe attacks than do patients in 11 other countries where Firazyr is also approved, a retrospective study shows. The disparity is thought to arise from a easier access to Firazyr in Germany and a public healthcare…

Daily treatment with BCX7353, an investigative oral inhibitor of plasma kallikrein, reduces the rate of attacks in hereditary angioedema (HAE) patients by more than 70%, a Phase 2 study shows. Also, more patients receiving the prophylactic, or preventive, treatment remained without an attack during the study’s four-week duration. The study,…

The U.S. Food and Drug Administration recently approved Shire’s Cinryze (C1 esterase inhibitor [human]) to help prevent angioedema attacks in children 6 and older who live with hereditary angioedema (HAE). Cinryze was first approved in the U.S. in 2008 for routine preventive treatment against attacks in…

Self-administration of Berinert was found to be safe and effective and reduces the need for emergency room visits during acute attacks in patients with hereditary angioedema type 1, according to researchers. Their study, “…
