Hereditary angioneurotic laryngeal edema (HALE) is an autosomal dominant hereditary disease in which there is a decrease or defect in the C1 inhibitor (C1-INH). The pathophysiology of HALE is characterized by recurrent spontaneous episodes of transient edema of the laryngeal mucose and submucosal tissue with remission at irregular. Patients may die because of a life-threatening acute upper airway obstruction caused by laryngeal edema. HALE was diagnosed on the clinical symptoms, family history, and markedly decreased serum C1-INH activity and C1-INH protein.

2.Migraine-like Headache in a Patient with Complement 1 Inhibitor Deficient Hereditary Angioedema.
Journal of Korean Medical Science 2012;27(1):104-106
We report on an angioedema patient with a genetic defect in complement 1 inhibitor, manifesting migraine-like episodes of headache, effective prophylaxis with Danazol, and triptan for a treatment of acute clinical episode. The patient was 44-yr-old Korean man with abdominal pain and headache, who was brought into the Emergency Department of Seoul National University Hospital, Seoul. He suffered from frequent attacks of migraine-like headache (3-7 per month), pulsating in nature associated with nausea. Severities were aggravated by activity and his headache had shown recent progression with abdominal pain. No remarkable findings were observed on radiologic examination, brain magnetic resonance images and intracranial and extracranial magnetic resonance angiography. Danazol 200 mg every other day was subsequently used. Following administration of Danazol, symptoms showed improvement and the patient was discharged. While taking Danazol, the migraine-like episodes appeared to be prevented for about 2 yr. At the eighth month, he suffered a moderate degree of migraine-like headache; however, administration of naratriptan 2.5 mg resolved his problem. A case of genetic defect of C1-INH deficiency presented with headache episodes, and was controlled by Danazol and triptan. It suggests that pathogenic mechanism of headache in hereditary angioedema may be mediated by the neurogenic inflammatory-like physiology of migraine.

Complement 1 (C1) inhibitor is an acute phase protein with anti-inflammatory properties. The aim of the present study was to elucidate the relationship between brachial ankle pulse wave velocity (baPWV), the parameter of arterial stiffness, and C1 inhibitor. One hundred subjects were randomly enrolled in this study. Data about baPWV, age, gender, hypertension, smoking, and body mass index (BMI) were measured. Blood tests for total cholesterol, low density lipoprotein, high density lipoprotein, triglycerides, hemoglobin A1c, erythrocyte sedimentation rate, C-reactive protein, complement 3, and C1 inhibitor were performed. Based on the Pearson correlation, the C1 inhibitor showed a positive relation to the baPWV (P<0.001). Multiple regression analysis revealed the significant predictors of baPWV were not only the conventional risk factors of arteriosclerosis and/or atherosclerosis, such as age (P<0.001), gender (P<0.001), hypertension (P<0.001), and BMI (P=0.006), but also the acute phase protein, C1 inhibitor (P=0.025). In conclusion, C1 inhibitor is associated with arterial stiffness through its association with increased inflammation.
