Urticaria (hives) is a common disorder that often presents with angioedema (swelling that occurs beneath the skin). It is generally classified as acute, chronic or physical. Second-generation, non-sedating H1-receptor antihistamines represent the mainstay of therapy for both acute and chronic urticaria. Angioedema can occur in the absence of urticaria, with angiotensin-converting enzyme (ACE) i...

The patient was a 38-year-old Japanese woman who had been diagnosed with hereditary angioedema type I at 7 years of age based on her family history. She had undergone four pregnancies. She gave birth to a healthy baby girl after her first pregnancy and had reported few episodes of angioedema. However, she subsequently required abortions due to frequent angioedema episodes that occurred during h...

Angioedema is the swelling of mucosal and sub-mucosal tissue. Typically, it manifests as the swelling of the face, lips, and tongue. Angioedema can be severe and life threatening when it involves the respiratory tract. Drug induced allergic angioedema and drug induced non-allergic angioedema differ in their mediator, their clinical presentations, and their management. In drug induced non-allerg...

BACKGROUND Angioedema is a common presentation in the emergency department (ED). Airway angioedema can be fatal; therefore, prompt diagnosis and correct treatment are vital. OBJECTIVE OF THE REVIEW Based on the findings of two expert panels attended by international experts in angioedema and emergency medicine, this review aims to provide practical guidance on the diagnosis, differentiation, ...

OBJECTIVES The purpose of this pictorial review is to present imaging findings of angioedema involving the various organs. CONCLUSION The role of imaging for patients with angioedema includes the evaluation of the upper airway for obstruction and the exclusion of other possible aetiologies, such as neoplastic or infectious processes. Glossomegaly is a common finding of head and neck angioedem...

conclusions due to considerable inter- and intra- heterogeneity among studies performed by other centers such as differences in study project, background, and population features, determining a pharmacotherapy model based on safe implementation of treatments in stroke or sits seem advantageous. results age, time of onset, systolic blood pressure, diabetes, stroke severity, co-morbidities and pr...

BACKGROUND Angiotensin-converting enzyme (ACE) inhibitors are associated with angioedema episodes that are potentially life-threatening. Few data are available on the outcome of patients reporting this adverse effect when they are switched to another drug. Scattered reports of angioedema associated with angiotensin II receptor blocker (ARB) use question the safety of using these drugs in patien...

Angioedema is defined as localized and self-limiting edema of the subcutaneous and submucosal tissue, due to a temporary increase in vascular permeability caused by the release of vasoactive mediator(s). When angioedema recurs without significant wheals, the patient should be diagnosed to have angioedema as a distinct disease. In the absence of accepted classification, different types of angioe...

Hereditary Angioedema is a dominantly inherited disease. Routine screening of autoantibodies (AAB) is not recommended for individuals with Hereditary Angioedema; however, prevalence of these antibodies in Hereditary Angioedema patients is not well documented. We aim to determine the prevalence of AAB so that individuals at risk of developing autoimmune diseases can be identified. Fifteen patien...

Background Angioedema is a highly heterogeneous group of conditions and is characterized by sudden, pronounced swelling of the lower dermis and subcutaneous. Because of its frequent coexistence with urticaria, it is often classified in the same manner as urticaria. However, it also includes categories not associated with urticaria. Angioedema without urticaria is characterized by hereditary and...
