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...

The causes of angioedema are not well described, especially in the inpatient setting. The purpose of this study was to examine the causes of moderate to severe angioedema in patients requiring inpatient treatment. We performed a retrospective review in patients requiring inpatient consultation by the Division of Allergy and Immunology at our institution between 1995 and 2004. We focused on pote...

BACKGROUND Hereditary angioedema is a rare autosomal dominantly inherited immunodeficiency disorder characterized by potentially life-threatening angioedema attacks. OBJECTIVE We aimed to investigate the clinical and genetic features of a family with angioedema attacks. METHODS The medical history, clinical features and C1-INH gene mutation of a Turkish family were investigated and outcomes...

Angioedema indicates acute subcutaneous edema that characterizes improperly restricted cutaneous or mucous membrane swelling, which can occur only once or be relapsing. Edema usually occurs in the periorbital area, lips, tongue, extremities and intestinal wall. It has turned out that angioedema is usually caused by the use of angiotensin-converting enzyme inhibitors (ACE) or allergies to certai...

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...

Angioedema is an underestimated clinical problem. Many cases are nonallergic reactions, e.g. bradykinin-induced angioedema caused by genetic defects and angiotensin-converting enzyme (ACE) inhibitors. This difference is crucial for successful therapy, in particular when complete emergency care is not available. Five important forms of nonallergic angioedema can be distinguished: hereditary (HAE...

angioedema is characterized by recurrent, circumscribed, solitary or multiple subcutaneous and mucosal swelling, involving the extremities, face, larynx, bowel wall. angioedema is due to hereditary or acquired varieties of c1 esterase inhibitor (c1inh) deficiency. a case of atypical acquired angioedema in a 49-year old man, responding favourably to cinnarizine and alcohol abstinence, is present...

BACKGROUND Angioedema is a rare but potentially serious adverse event of angiotensin-converting enzyme inhibitor therapy. However, no prospective, controlled studies have reported on its incidence and clinical characteristics. METHODS We studied the occurrence of angioedema in a randomized, double-blind, controlled trial of 12 557 persons with hypertension treated with enalapril maleate, 5 to...

OBJECTIVES/HYPOTHESIS To evaluate the etiology and risk factors for severe manifestation and recurrent episodes of angioedema; to evaluate efficacy of short-term and long-term management strategies for angioedema among a high-risk population. STUDY DESIGN Institutional review board-approved retrospective review of a large, urban population. METHODS Data from 875 adult patients treated from ...

Acute allergic angioedema is an abrupt-onset, unpredictable inflammatory reaction of the skin and mucous membranes. Without treatment, the condition may resolve within hours; however, when swallowing or breathing is affected, emergent medical attention is required. We report an atypical presentation of this condition, with a unique dietary cause. A 50-year-old man with no relevant medical histo...
