High Estrogen States in Hereditary Angioedema : a Spectrum

Sex differences have been well documented within hereditary angioedema (HAE) over the past several decades. Females often experience more frequent and more intense attacks compared to their male counterparts. Additionally, elevated estrogen levels-as seen in pregnancy and use of oral contraceptives-is a widely known trigger for angioedema attacks. In this review article, we will outline how estrogens' downstream effects increase bradykinin, a potent vasodilator and key mediator of HAE. Estrogen-dependent HAE is a rare disorder that provides insight into the relationship between HAE and estrogens. Females affected by this subtype of HAE only experience attacks when under "high estrogen states," such as during pregnancy and when taking exogenous estrogens (most commonly, oral contraceptives). This unique phenotype has been documented in individuals with an activating Factor XII mutation. Thus, based on this clear genotype-phenotype relationship, we conclude that Factor XII may be key in our understanding of estrogens' role in HAE. Lastly, we propose that the sex differences seen in HAE be viewed as a spectrum from exacerbation to underlying genetic mutations in Factor XII.
