HAE in the paediatric patient

For patients with HAE, symptoms usually manifest first in childhood; however, it is often many years until a correct diagnosis is made. Diagnosing HAE in childhood is vital for optimal disease management. Dr. Weber explains symptoms to look out for in paediatric patients, potential triggers for attacks, and considerations specific for children with HAE.

“The fear of laryngeal attacks is an important factor for anxiety in patients with HAE”

HAE from the otolaryngologist’s perspective

Dr. Susanne Trainotti

Around 50% of patients with HAE suffer a laryngeal attack in their lifetime. It is a frightening experience and can be life-threatening, which itself results in anxiety in patients with HAE. Dr. Trainotti details early symptoms an otolaryngologist may encounter during an HAE attack, and treatment strategies if there is a high suspicion of HAE.

“Appropriate treatment will prevent needless suffering and useless surgical procedures”

HAE and gastroenterology

Professor Giuseppe Spadaro

.

The gastrointestinal manifestations of HAE are similar to more common conditions and may occur without swellings. Combined with the fact that HAE is a rare disease, this presents a diagnostic challenge. Professor Spadaro stresses the importance of a correct diagnosis to prevent unnecessary abdominal surgery that is common in patients with HAE.
