Hereditary angio-oedema in Denmark: a nationwide survey

Abstract

The minimal prevalence of HAE in Denmark is approximately 1.41 per 100 000 inhabitants. The risk of upper airway obstruction underlines the importance of diagnosing these patients. Precipitating factors, a preceding or concomitant serpiginous erythema and cutaneous swelling and/or abdominal pain attack and/or laryngeal oedema are clues to the diagnosis. As a consequence of this survey, information has been spread to patients, families and physicians.
