On the role of the C1-esterase inhibitor in cold urticaria. 1984

T Nilsson, and O Bäck

Plasma samples from 20 patients with acquired cold urticaria were studied. The C1-esterase inhibitor activity was found to be low, but the total C1-esterase inhibitor concentration was normal. Prekallikrein, plasmin-alpha 2-antiplasmin complex, and kallikrein-like activity were also found to be within normal limits. Cold-promoted activation of coagulation factor VII occurred in 45% of the patient plasmas and resulted in a considerable drop in C1-esterase inhibitor activity.

UI	MeSH Term	Description	Entries
D007610	Kallikreins	Proteolytic enzymes from the serine endopeptidase family found in normal blood and urine. Specifically, Kallikreins are potent vasodilators and hypotensives and increase vascular permeability and affect smooth muscle. They act as infertility agents in men. Three forms are recognized, PLASMA KALLIKREIN (EC 3.4.21.34), TISSUE KALLIKREIN (EC 3.4.21.35), and PROSTATE-SPECIFIC ANTIGEN (EC 3.4.21.77).

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011288	Prekallikrein	A plasma protein which is the precursor of kallikrein. Plasma that is deficient in prekallikrein has been found to be abnormal in thromboplastin formation, kinin generation, evolution of a permeability globulin, and plasmin formation. The absence of prekallikrein in plasma leads to Fletcher factor deficiency, a congenital disease.

D005167	Factor VII	Heat- and storage-stable plasma protein that is activated by tissue thromboplastin to form factor VIIa in the extrinsic pathway of blood coagulation.
