Icatibant로 급성 악화를 치료한 제2형 유전성혈관부종 1예

Hereditary angioedema (HAE) is a rare autosomal dominant disorder caused by genetic deficiency or decreased function of C1-esterase inhibitor. It is characterized by swelling of subcutaneous and submucosal tissues of the extremities, gastrointestinal tract, and upper airways which can be life-threatening. Thus, early recognition and treatment of the disease are important. Short- and long-term prophylaxes are used to decrease the severity and frequency of attacks. Icatibant is a selective bradykinin B2-receptor antagonist, earlier treatment of acute attacks and hospital admission. The authors present a case of 47-year-old woman who was diagnosed with type II HAE, danazol as a long term. Her symptoms improved dramatically after drug treatment. The unpredictability and recurrence of HAE attacks could have a negative impact on social life and quality of life. This case shows that timely and proper treatment could improve quality of life and reduce morbidity and mortality. (Allergy Asthma Respir Dis 2021;9:180-183)
