It follows an autosomal dominant inheritance pattern and affects both sexes equally;\n however, attacks may occur more frequently and with greater severity in women due to hormonal factors.\n                    <jats:bold>Aims:<\/jats:bold>\n                    The aim of this study was to evaluate the impact of hormonal changes on HAE attacks in women and to determine how different reproductive stages and hormonal exposures\n affect attack frequency and course.\n                    <jats:bold>Methods:<\/jats:bold>\n                    In this retrospective descriptive cohort study, 36 postpubertal women with HAE were evaluated to assess the effects of reproductive factors, including menstruation, oral contraceptive use, pregnancy, delivery, lactation, and\n menopause, on attack frequency and disease activity.\n                    <jats:bold>Results:<\/jats:bold>\n                    Thirty patients had type I and six had type II HAE. The mean age at diagnosis was 23.5 years, with a mean diagnostic delay of 12.6 years. Menstruation triggered attacks in 52.8% of the patients. Among 26 patients\n with 94 pregnancies, 21.2% ended in spontaneous abortion, and 73.1% had at least one child diagnosed with HAE. During pregnancy, attack frequency increased in 30.6%, decreased in 27.7%, and was unchanged in 41.7%. Attacks occurred within 48 hours postpartum in six deliveries, and three patients\n reported increased attacks during lactation. After menopause, attacks increased in 25%, decreased in 33.3%, and were unchanged in 41.7%.\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    Hormonal and reproductive life stages influence disease activity in women with HAE, although the direction and magnitude\n of these effects vary among individuals. The marked delay in diagnosis observed in this cohort suggests that many women experience pregnancies without disease-specific management. Earlier recognition of HAE and individualized treatment approaches may improve care during hormonally dynamic\n periods.\n                  <\/jats:p>","DOI":"10.2500\/aap.2026.47.260054","type":"journal-article","created":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T04:50:20Z","timestamp":1788583820000},"page":"348-353","source":"Crossref","is-referenced-by-count":1,"title":["Hereditary angioedema in women: Hormonal and reproductive influences on disease activity"],"prefix":"10.2500","volume":"47","author":[{"given":"Reyhan S.","family":"Cansunar","sequence":"first","affiliation":[{"name":"From the Division of Immunology and Allergy, Adana City Training and Research Hospital, Adana, Turkey and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merve","family":"Erkoc Karaduman","sequence":"additional","affiliation":[{"name":"Division of Immunology and Allergy, Prof. Dr. Feriha \u00d6z Emergency Hospital, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leyla","family":"Cevirme","sequence":"additional","affiliation":[{"name":"From the Division of Immunology and Allergy, Adana City Training and Research Hospital, Adana, Turkey and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hakan","family":"Basir","sequence":"additional","affiliation":[{"name":"From the Division of Immunology and Allergy, Adana City Training and Research Hospital, Adana, Turkey and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guzin","family":"Ozden","sequence":"additional","affiliation":[{"name":"From the Division of Immunology and Allergy, Adana City Training and Research Hospital, Adana, Turkey and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1355","reference":[{"key":"B1","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1016\/j.iac.2022.05.011","article-title":"Hereditary angioedema during pregnancy: considerations in management","volume":"43","author":"Riedl","year":"2023","journal-title":"Immunol Allergy Clin North Am"},{"key":"B2","doi-asserted-by":"crossref","first-page":"484.e1\u2013e4","DOI":"10.1016\/j.ajog.2008.04.034","article-title":"Disease expression in women with hereditary angioedema","volume":"199","author":"Bouillet","year":"2008","journal-title":"Am J Obstet Gynecol"},{"key":"B3","doi-asserted-by":"crossref","first-page":"132","DOI":"10.1016\/j.jaip.2020.08.046","article-title":"US HAEA Medical Advisory Board 2020 guidelines for the management of hereditary angioedema","volume":"9","author":"Busse","year":"2021","journal-title":"J Allergy Clin Immunol Pract"},{"key":"B4","doi-asserted-by":"crossref","first-page":"100906","DOI":"10.1016\/j.waojou.2024.100906","article-title":"Hereditary angioedema classification: expanding knowledge by genotyping and endotyping","volume":"17","author":"Giavina-Bianchi","year":"2024","journal-title":"World Allergy Organ J"},{"key":"B5","doi-asserted-by":"crossref","first-page":"351","DOI":"10.2217\/whe.16.6","article-title":"Managing the female patient with hereditary angioedema","volume":"12","author":"Banerji","year":"2016","journal-title":"Womens Health (Lond)"},{"key":"B6","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1186\/s13223-022-00689-9","article-title":"Considerations in the management of hereditary angioedema due to C1-INH deficiency in women of childbearing age","volume":"18","author":"Hsu","year":"2022","journal-title":"Allergy Asthma Clin Immunol"},{"key":"B7","doi-asserted-by":"crossref","first-page":"445","DOI":"10.5114\/ada.2020.98226","article-title":"Angioedema.
