C1 esterase inhibitor is a single chain glycoprotein which inhibits C1, C1r, C1s, plasma kallikrein, factors XIa, XIIa and plasmin of the blood clotting system. It is present in the plasma at 16-33 mg/100mL. It is part of the serpin family Background: Hereditary angioedema (HAE) is a life-threatening, autosomal dominant disorder characterized by unpredictable, episodic swelling of the face, upper airway, oropharynx, extremities, genitalia, and gastrointestinal tract. Almost all cases of HAE are caused by mutations in the SERPING1 gene resulting in a deficiency in functional plasma C1 esterase inhibitor (C1EI), a serine protease. Do not use RUCONEST if you have experienced life-threatening immediate hypersensitivity reactions, including anaphylaxis, to RUCONEST or to any other C1 esterase inhibitor (C1-INH) product. Call your healthcare professional or the emergency department right away if you experience: wheezing, difficulty breathing, chest tightness, turning blue (look at lips and gums), fast heartbeat, swelling, faintness, rash or hives C1 esterase inhibitor deficiency results in hereditary angioedema. This disease is autosomal dominant and exhaustion of the low levels of C1 esterase inhibitor results in C1 activation, breakdown of C2 and C4, and subsequent acute edema of subcutaneous tissue, the gastrointestinal tract, or the upper respiratory tract FC1EQ - Overview: C1 Esterase Inhibitor, Functional Assay, Serum.
