Hereditary angioedema: Epidemiology and burden of disease

William R Lumry1, Russell A Settipane2

  • 1From the University of Texas Southwestern Medical School, Dallas, Texas.

Hereditary angioedema (HAE) is a rare autosomal dominant genetic disorder characterized by swelling of subcutaneous, mucosal, and submucosal tissue without associated pruritus or wheals caused by a temporary localized increase in vascular permeability. Swelling attacks primarily affect the cutaneous tissue, abdominal viscera, genitals, or airways. <title/> Reports of the prevalence of HAE C1 inhibitor (C1-INH) deficiency varies widely, from 1:50,000 to 1:100,000. The prevalence of HAE normal C1-INH is unknown but is likely much lower than HAE C1-INH. Approximately one-third of patients with recurrent angioedema without wheals have HAE. <title/> The burden of disease for patients with HAE is substantial. Attacks are unpredictable with respect to frequency, severity, and the site that swells. Laryngeal attacks can be fatal if not treated promptly and appropriately. Feelings of stress, anxiety, and depression can trigger attacks, and begin a cycle of attacks that cause anxiety that, in turn, triggers further attacks. Despite full physical recovery between attacks, patients often experience continual emotional impairment and reduced quality of life (QoL). Absenteeism from work and presenteeism at work or educational activities for patients and caregivers increase stress and reduce productivity during and between attacks. Missed opportunities for career development are common. <title/> Significant advances have been made in the past decade to expand both acute and prophylactic treatment options for patients with HAE, lowering both the disease and treatment burden, and improving the QoL of patients with HAE.</p><button type="button" class="mt-1 cursor-pointer border-none bg-transparent p-0 font-inter text-sm font-medium text-primary hover:underline">Show more</button></div></div><div class="hidden flex-col gap-4 md:flex"><div class="flex flex-col gap-0"><div class="flex flex-col gap-3"><p class="font-inter text-sm leading-6 text-secondary"><title/> Hereditary angioedema (HAE) is a rare autosomal dominant genetic disorder characterized by swelling of subcutaneous, mucosal, and submucosal tissue without associated pruritus or wheals caused by a temporary localized increase in vascular permeability.

Swelling attacks primarily affect the cutaneous tissue, abdominal viscera, genitals, or airways. Reports of the prevalence of HAE C1 inhibitor (C1-INH) deficiency varies widely, from 1:50,000 to 1:100,000. The prevalence of HAE normal C1-INH is unknown but is likely much lower than HAE C1-INH. Approximately one-third of patients with recurrent angioedema without wheals have HAE. The burden of disease for patients with HAE is substantial. Attacks are unpredictable with respect to frequency, severity, and the site that swells. Laryngeal attacks can be fatal if not treated promptly and appropriately. Feelings of stress, anxiety, and depression can trigger attacks, and begin a cycle of attacks that cause anxiety that, in turn, triggers further attacks. Despite full physical recovery between attacks, patients often experience continual emotional impairment and reduced quality of life (QoL). Absenteeism from work and presenteeism at work or educational activities for patients and caregivers increase stress and reduce productivity during and between attacks. Missed opportunities for career development are common. Significant advances have been made in the past decade to expand both acute and prophylactic treatment options for patients with HAE, lowering both the disease and treatment burden, and improving the QoL of patients with HAE."])</script><script>self.__next_f.push([1,"1c:[\"$\",\"div\",null,{\"className\":\"mx-auto w-full lg:mb-8\",\"data-testid\":\"article-page\",\"children\":[[\"$\",\"$L1f\",null,{\"schemas\":[{\"@context\":\"https://schema.org\",\"@type\":\"Organization\",\"@id\":\"https://visualize.jove.com#organization\",\"name\":\"JoVE Visualize\",\"url\":\"https://visualize.jove.com\",\"logo\":{\"@type\":\"ImageObject\",\"@id\":\"https://visualize.jove.com#logo\",\"url\":\"https://visualize.jove.com/images/logo.png\",\"contentUrl\":\"https://visualize.jove.com/images/logo.png\",\"caption\":\"JoVE Visualize\",\"inLanguage\":\"en-US\",\"width\":112,\"height\":112}},{\"@context\":\"https://schema.org\",\"@type\":\"WebSite\",\"@id\":\"https://visualize.jove.com#website\",\"url\":\"https://visualize.jove.com\",\"name\":\"JoVE Visualize\",\"alternateName\":\"Visualize\",\"publisher\":{\"@id\":\"https://visualize.jove.com#organization\"},\"inLanguage\":\"en-US\"},{\"@context\":\"https://schema.org\",\"@type\":\"WebPage\",\"@id\":\"https://visualize.jove.com/33109318-hereditary-angioedema-epidemiology-and-burden-of-disease#webpage\",\"url\":\"https://visualize.jove.com/33109318-hereditary-angioedema-epidemiology-and-burden-of-disease\",\"name\":\"Related Videos - Hereditary angioedema: Epidemiology and burden of disease\",\"isPartOf\":{\"@id\":\"https://visualize.jove.com#website\"},\"inLanguage\":\"en-US\",\"mainEntity\":{\"@id\":\"https://visualize.jove.com/33109318-hereditary-angioedema-epidemiology-and-burden-of-disease#article\"}},{\"@context\":\"https://schema.org\",\"@type\":\"ScholarlyArticle\",\"name\":\"Hereditary angioedema: Epidemiology and burden of disease\",\"abstract\":\"$20\",\"datePublished\":\"2020-10-28T00:00:00\",\"url\":\"https://visualize.jove.com/33109318-hereditary-angioedema-epidemiology-and-burden-of-disease\",\"isPartOf\":{\"@type\":\"Periodical\",\"name\":\"Allergy and asthma proceedings\"},\"author\":[{\"@type\":\"Person\",\"name\":\"William R Lumry\",\"affiliation\":{\"@type\":\"Organization\",\"name\":\"From the University of Texas Southwestern Medical School, Dallas, Texas.\"}},{\"@type\":\"Person\",\"name\":\"Russell A Settipane\",\"affiliation\":{\"@type\":\"Organization\",\"name\":\"Warren Alpert Medical School, Brown University, Providence, RI.\"}}],\"@id\":\"https://visualize.jove.com/33109318-hereditary-angioedema-epidemiology-and-burden-of-disease#article\",\"publisher\":{\"@id\":\"https://visualize.jove.com#organization\"},\"inLanguage\":\"en-US\",\"dateModified\":\"2025-07-24T00:00:00\"}]}],\"$L21\",\"$L22\",\"$L23\"]}]\n"])</script><script>self.__next_f.push([1,"1d:[\"$\",\"$L24\",null,{}]\n"])</script><script>self.__next_f.push([1,"1e:[\"$\",\"$L25\",null,{\"lang\":\"en\",\"initialData\":{\"pmid\":33109318,\"related_by_author\":[{\"pmid\":42570170,\"doi\":\"10.1007/s12016-026-09179-x\",\"title\":\"Lanadelumab Use for Hereditary Angioedema Long-Term Prophylaxis Over the Last 7 Years: A Narrative Review of Clinical and Real-World Data.\",\"journal_title\":\"Clinical reviews in allergy \u0026 immunology\",\"publish_date\":\"2026-08-08T00:00:00\"},{\"pmid\":42436759,\"doi\":\"10.1016/j.jacig.2026.100750\",\"title\":\"Sebetralstat for breakthrough attacks in patients with hereditary angioedema receiving long-term prophylaxis in KONFIDENT-S.\",\"journal_title\":\"The journal of allergy and clinical immunology.

Approximately one-third of patients with recurrent angioedema without wheals have HAE. \u003ctitle/\u003e The burden of disease for patients with HAE is substantial. Attacks are unpredictable with respect to frequency, severity, and the site that swells. Laryngeal attacks can be fatal if not treated promptly and appropriately. Feelings of stress, anxiety, and depression can trigger attacks, and begin a cycle of attacks that cause anxiety that, in turn, triggers further attacks. Despite full physical recovery between attacks, patients often experience continual emotional impairment and reduced quality of life (QoL). Absenteeism from work and presenteeism at work or educational activities for patients and caregivers increase stress and reduce productivity during and between attacks.
