C1- inhibitor (C1(-)-Inh) catabolism in plasma of patients with hereditary angioneurotic edema (HANE) was assessed by measuring the complexes formed by C1(-)-Inh with its target proteases (C1-s, Factor XIIa, and kallikrein) and a modified (cleaved) inactive form of C1(-)-Inh (iC1(-)-Inh). This study was performed in plasma from 18 healthy subjects and 30 patients with HANE in remission: 20 with...
Angioedema related to a deficiency in the C1-inhibitor protein is characterized by its lack of response to therapies including antihistamine, steroids, and epinephrine. In the case of laryngeal edema, mortality rate is approximately 30 percent. The first case of the acquired form of angioedema related to a deficiency in C1-inhibitor was published in 1972. In our paper, we present a case of an a...
C1 inhibitor plays an important role in the regulation of vascular permeability through its ability to inactivate enzymes which release polypeptide kinins. Dysfunctional C1 inhibitor molecules are present in the plasma of affected members of the Da and Ri hereditary angioneurotic edema kindreds. We constructed genomic libraries from Da and Ri patient DNAs which had been cleaved with BclI to gen...
Angioedema of the upper airways is a severe and potentially life-threatening condition. The incidence has been increasing in the past two decades, primarily due to pharmaceuticals influencing the generation or degradation of the vasoactive molecule bradykinin. Plasma-derived C1-esterase inhibitor concentrate is a well-established treatment option of hereditary and acquired complement C1-esteras...
Background: Hereditary angioedema (HAE) is a rare autosomal dominant primary immunodeficiency with complement system defect characterized by recurrent episodes of angioedema involving the skin or mucosa of the upper respiratory and gastrointestinal tracts. Objective: To characterize the clinical and laboratory data of hereditary angioedema in Iran. Methods: Patients with probable diagnosis of a...
