BACKGROUND: Hereditary angio-oedema (HAE) is an autosomal dominant condition caused by a deficiency in the C1-esterase inhibitor protein, resulting in increased bradykinin release. It presents clinically with recurrent attacks of angio-oedema, commonly affecting the limbs, face, upper airway and gastrointestinal tract. Little is known about this condition in sub-Saharan Africa. OBJECTIVES: To analyse and report on the clinical presentation and treatment of patients with HAE in the Western Cape Province, South Africa...

Acquired angioedema due to C1 inhibitor deficiency (C1INH-AAE) is a rare and potentially fatal syndrome of bradykinin-mediated angioedema characterized by episodes of angioedema without urticaria. It typically manifests with nonpitting edema of the skin and edema in the gastrointestinal (GI) tract mucosa or upper airway. Edema of the upper airway and tongue may lead to life-threatening asphyxiation. C1INH-AAE is typically under-diagnosed because of its rarity and its propensity to mimic more common abdominal conditions and allergic reactions...

BACKGROUND AND PURPOSE: Non-allergic angio-oedema is a life threatening disease mediated by activation of bradykinin type 2 receptors (B2). The aim of this study was to investigate whether activation of B2 by endogenous bradykinin contributes to physiologic extravasation. This may shed new light on the assumption that treatment with an ACEi results in an alteration of the vascular barrier function predisposing to non-allergic angio-edema. EXPERIMENTAL APPROACH: We generated a new transgenic mouse model characterized by endothelium-specific overexpression of B2 (B2tg ) and established a non-invasive two-photon laser microscopy approach to measure the kinetics of spontaneous extravasation in-vivo...

Objective Angioedema is a potentially life-threatening complication of angiotensin-converting enzyme inhibitor (ACEI) use, occurring in up to 0.5% of users. Although the pathophysiology of ACEI-induced angioedema is attributable to elevated serum bradykinin, standard management typically includes corticosteroids and antihistamines. We sought to summarize the evidence supporting pharmacotherapy for ACEI-induced angioedema. Data Sources PubMed, MEDLINE, and Embase portals. Methods A systematic literature review was conducted according to the PRISMA guidelines...

Severe orolingual angioedema is a life-threatening complication of alteplase treatment for acute ischemic stroke that occurs during alteplase infusion or in the first 2 hours afterward. Currently, there are no proven therapies, although glucocorticoids, antihistamines, and adrenaline are sometimes used. Intubation is required if significant airway compromise supervenes. The incidence is .2%-5.1%, and risk factors include treatment with angiotensin-converting enzyme inhibitors and total insular infarcts. Here we report a case of alteplase-induced severe angioedema, which resolved briskly following icatibant treatment...

BACKGROUND: Hereditary angioedema (HAE) is a life-long disease that often manifests by puberty. Treatment of attacks is essential to improve quality of life and to decrease morbidity and mortality. During pregnancy, treatment is limited because multiple treatment options, including icatibant, are not approved for use during pregnancy. OBJECTIVE: We report the outcomes of three pregnancies during which icatibant was used by a patient with HAE with normal C1-inhibitor for treatment of attacks...

BACKGROUND: Angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema can occur at any point during therapy and, when severe, can require mechanical ventilation. Standard agents for anaphylactic reactions have limited efficacy for bradykinin-mediated angioedema and, therefore, agents approved for hereditary angioedema are increasingly prescribed for these patients. OBJECTIVE OF THE REVIEW: This systematic review critically evaluates evidence describing the off-label use of fresh frozen plasma (FFP), prothrombin complex concentrate (PCC), complement 1 esterase inhibitor (C1-INH), icatibant, and ecallantide for treatment of ACEI-induced angioedema...

BACKGROUND: Idiopathic non-histaminergic acquired angioedema (InH-AAE) is a rare disease for which there are no available laboratory parameters to clearly define the disorder. Therapy is often difficult and various treatment options have been proposed. In this paper, we have evaluated the most effective therapies for InH-AAE on the basis of current literature and report the therapeutic effect of omalizumab in three patients with InH-AAE. METHODS: Literature was searched with a combination of MeSH/EMTREE terms and freetext search for angioedema and therapy/omalizumab in the databases Medline (Ovid), PubMed/Premedline, Embase, Cochrane library and Scopus with no time or language restrictions...

The benefits of the worldwide approval of new drugs for the treatment of acute C1-INH-HAE attacks may still not reach all patients. Identifying the current barriers in the access to medication, as well as conducting a detailed assessment of the progress in this area, is essential to achieve universal treatment. Two hundred and twenty five patients registered in the Argentina Hereditary Angioedema Patient Association (AHAEPA) were randomly selected and invited to participate in a web based questionnaire on accessibility to icatibant and pdC1-INH, self-treatment, delay to treatment, and coverage...

Reported results have shown that the pentapeptide opiorphin inhibits oligopeptidases that degrade brain neuropeptides, and has analgesic and antidepressant effects in experimental animals, without either tolerance or dependency after chronic administration. In a previous study we showed that opiorphin has a panicolytic-like effect in the dorsal periaqueductal gray (dPAG) electrical stimulation test (EST), mediated by the μ-opioid receptor (MOR). This study further analyzes the mechanism of opiorphin panicolytic action, using the EST and drug injection inside the dPAG...

BACKGROUND: Patients with hereditary angioedema (HAE) due to C1-inhibitor deficiency (C1-INH-HAE) experience recurrent attacks of cutaneous or submucosal edema that may be frequent and severe; prophylactic treatments can be prescribed to prevent attacks. However, despite the use of long-term prophylaxis (LTP), breakthrough attacks are known to occur. We used data from the Icatibant Outcome Survey (IOS) to evaluate the characteristics of breakthrough attacks and the effectiveness of icatibant as a treatment option...

REVIEW
Constance H Katelaris
Several treatment modalities have become available for management of acute hereditary angioedema (HAE) attacks in the last 15 years. Most are now available to patients in North America, Europe, United Kingdom, and Australia, but few options exist in developing countries. Preferred contemporary use of the treatments to be discussed is "on demand," because control remains with the patient and delays in treatment access avoided. Four treatments-plasma-derived C1 inhibitor concentrate, recombinant C1 inhibitor concentrate, ecallantide, and icatibant-are reviewed in this article...

REVIEW
Iris M Otani, Aleena Banerji
Acquired angioedema due to C1-INH deficiency (C1-INH-AAE) can occur when there are acquired (not inherited) deficiencies of C1-INH. A quantitative or functional C1-INH deficiency with negative family history and low C1q is diagnostic of C1-INH-AAE. The most common conditions associated with C1-INH-AAE are autoimmunity and B-cell lymphoproliferative disorders. A diagnosis of C1-INH-AAE can precede a diagnosis of lymphoproliferative disease and confers an increased risk for developing non-Hodgkin lymphoma. Treatment focuses on symptom control with therapies that regulate bradykinin activity (C1-INH concentrate, icatibant, ecallantide, tranexamic acid, androgens) and treatment of any underlying conditions...

BACKGROUND: Clinical manifestations of hereditary angioedema with C1 inhibitor deficiency (C1-INH-HAE) usually begin in childhood, often intensifying during puberty. Currently there are insufficient efficacy/safety data for HAE therapies in children and adolescents due to the small number of pediatric patients enrolled in studies. OBJECTIVE: The objective of this phase 3 study was to evaluate the efficacy/safety of a single subcutaneous dose of icatibant (0.4 mg/kg; maximum 30 mg) in pediatric patients with C1-INH-HAE...

BACKGROUND: Upper airway angioedema is a rare, unpredictable, and at times life-threatening adverse effect of angiotensin-converting enzyme inhibitors (ACE-Is) with no existing effective pharmacologic treatment. Icatibant is a bradykinin B2 receptor antagonist that may be beneficial in patients with ACE-I-induced angioedema. OBJECTIVE: We aimed to evaluate the efficacy of icatibant in subjects with ACE-I-induced angioedema. METHODS: At 31 centers in 4 countries, adults on ACE-Is who presented within 12 hours of the onset of at least moderately severe angioedema were randomized 1:1 to icatibant 30 mg or placebo administered subcutaneously...
