HAE attacks

HAE is characterized by unpredictable, recurrent, and sometimes painful edema attacks that can affect extremities, genitals, the face, gastrointestinal (GI) tract and upper airways. They are generally categorized according to anatomical site as cutaneous, abdominal or laryngeal. The symptoms of each attack type are listed below.1,2

Attacks: Cutaneous

  • Typically affects face, extremities and genitals2
  • Can be disabling and disfiguring at the time of the attack2
  • Facial swelling can extend to laryngeal edema3*

Attacks: Laryngeal

  • Approximately 50% of patients may suffer a laryngeal attack in their lifetime3*
  • These can cause death by asphyxiation, even with no history of laryngeal involvement4

The site at which the HAE attack occurs varies among patients. Some patients experience simultaneous or closely spaced abdominal and cutaneous involvement.2

In a retrospective analysis of 209 patients presenting with symptoms of HAE, 96% of patients experienced cutaneous edema, including facial swelling; 93% had recurrent abdominal attacks; approximately 52% had laryngeal attacks (the total number of laryngeal attacks represented 0.9% of all attacks).3
