Initial use of subcutaneous plasma-derived C1 inhibitor in prophylaxis of acute attacks of hereditary angioedema in pregnant patients in Slovakia.

Hereditary angioedema (HAE) is a rare, inborn disease manifested with recurrent attacks of angioedema. They can affect the skin and subcutaneous tissue, mucous membranes (gastrointestinal, respiratory, and uropoietic tracts), and submucous tissue. Women in reproductive age require specific management of the disease regarding both the course of the disease and treatment options. It is not only the treatment in female patients that is specific, but also the situations (pregnancy, breastfeeding). We present a case report of the initial use of a subcutaneous C1 inhibitor in the long-term prophylaxis of HAE attacks in two pregnant patients.
