Hereditary angioedema type 1 and 2 are due to a deficiency in C1--esterase inhibitor. This molecule inhibits the generation of bradykinin, a potent inflammatory mediator that increases vascular permeability. Upon accumulation of bradykinin, patients affected develop painful subcutaneous or submucosal edemas that last for several days. In case the upper airways are affected, there is risk of suffocation. This type of angioedema does not respond to antihistamines, cortico-steroids or epinephrine. Management of angioedema attacks consists in injecting C1-esterase inhibitor concentrate or icatibant, a bradykinin receptor B2 antagonist. Preventive measures aim at reducing the frequency and the severity of angioedema attacks. Inhibition of -plasma kallikrein by lanadelumab, a monoclonal antibody adminis-tered subcutaneously, is effective and well tolerated.

UI	MeSH Term	Description	Entries
D001920	Bradykinin	A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.

D050718	Complement C1 Inhibitor Protein	An endogenous 105-kDa plasma glycoprotein produced primarily by the LIVER and MONOCYTES. It inhibits a broad spectrum of proteases, including the COMPLEMENT C1R and the COMPLEMENT C1S proteases of the CLASSICAL COMPLEMENT PATHWAY, and the MANNOSE-BINDING PROTEIN-ASSOCIATED SERINE PROTEASES. C1-INH-deficient individuals suffer from HEREDITARY ANGIOEDEMA TYPES I AND II.
