Blood Clotting and the Pathogenesis of Types I and II Hereditary Angioedema.

Clin Rev Allergy Immunol 2021 May 6. Epub 2021 May 6.

Department of Medicine, Medical University of South Carolina, Charleston, SC, USA.

The plasma contact system is the initiator of the intrinsic pathway of coagulation and the main producer of the inflammatory peptide bradykinin. When plasma is exposed to a negatively charged surface the two enzymes factor XII (FXII) and plasma prekallikrein (PK) bind to the surface alongside the co-factor high molecular weight kininogen (HK), where PK is non-covalently bound to. Here, FXII and PK undergo a reciprocal activation feedback loop that leads to full contact system activity in a matter of seconds. Read More

Chronic Urticaria and Recurrent Angioedema: Clues to the Mimics.

J Allergy Clin Immunol Pract 2021 Apr 24. Epub 2021 Apr 24.

Department of Dermatology, Mayo Clinic Rochester, Rochester, Minn.

Urticaria and angioedema are experienced by up to 1 in 5 people, usually the result of common allergen or medication triggers and infections. Similarly, the majority of recurrent angioedema has an exogenous trigger, for example, angiotensin converting enzyme inhibitors, or is hereditary (type 1 and 2 hereditary angioedema); chronic spontaneous urticaria are most often autoimmune or autoallergic in routine clinical practice. There are, however, several skin and systemic conditions that can imitate the clinical appearance of either angioedema or urticaria, whereas there are several uncommon conditions that have chronic urticaria and/or recurrent angioedema as part of their disease manifestations.

Recognition, Evaluation, and Management of Pediatric Hereditary Angioedema.

Pediatr Emerg Care 2021 Apr;37(4):218-223

Professor of Pediatrics, Department of Pediatrics, Division of Emergency Medicine, Cincinnati Children's Hospital Medical Center, and University of Cincinnati Department of Pediatrics, Cincinnati, OH.

Abstract: Hereditary angioedema (HAE) is a rare, often underrecognized genetic disorder caused by either a C1 esterase inhibitor deficiency (type 1) or mutation (type 2). This leads to overproduction of bradykinin resulting in vasodilation, vascular leakage, and transient nonpitting angioedema occurring most frequently in the face, neck, upper airway, abdomen, and/or extremities. Involvement of the tongue and laryngopharynx has been associated with asphyxiation and death. Read More
