Hereditary angioedema (HA) is caused by a quantitative or qualitative deficiency of C1 esterase inhibitor (C1 INH). We present a study of nine patients with HA belonging to two different families. The symptoms started before 10 years of age in most cases (78%). Facial edema (lips, eyes) and of the extremities (feet, hands) were the most frequent complaints. Three patients presented edema of the glottis and one of them underwent a tracheostomy twice. Laboratory tests, outside the acute crisis, revealed low levels of C4 in all patients. The serum levels of C1 INH were normal in seven patients; however, functional activity was not observed in any of them. After the use of a modified androgen (danazol), control of symptoms was observed in all patients, although functional activity was re-established in only five patients.
遗传性血管性水肿(HA)由C1酯酶抑制剂(C1 INH)的数量或质量缺陷引起。我们对来自两个不同家族的9例HA患者进行了一项研究。多数病例(78%)症状始于10岁之前。面部水肿(嘴唇、眼睛)和四肢(足部、手部)水肿是最常见的主诉。3例患者出现声门水肿,其中1例接受了两次气管切开术。在急性发作期之外的实验室检查显示,所有患者的C4水平均较低。7例患者的C1 INH血清水平正常;然而,未观察到其中任何1例有功能活性。使用改良雄激素(达那唑)后,所有患者的症状均得到控制,不过仅5例患者的功能活性得以恢复。
