Complement C1 Esterase Inhibitor Levels Linked to Infections and Contaminated Heparin-Associated Adverse Events
Activation of kinin-kallikrein and complement pathways by oversulfated-chondroitin-sulfate (OSCS) has been linked with recent heparin-associated adverse clinical events. Given the fact that the majority of patients who received contaminated heparin did not experience an adverse event, it is of particular importance to determine the circumstances that increase the risk of a clinical reaction. In...
متن کاملContaminated heparin associated with adverse clinical events and activation of the contact system.
BACKGROUND There is an urgent need to determine whether oversulfated chondroitin sulfate (OSCS), a compound contaminating heparin supplies worldwide, is the cause of the severe anaphylactoid reactions that have occurred after intravenous heparin administration in the United States and Germany. METHODS Heparin procured from the Food and Drug Administration, consisting of suspect lots of hepari...
متن کاملCLINICAL REVIEW Acquired C1 Esterase Inhibitor Deficiency
Acquired C1 esterase inhibitor deficiency is a rare condition associated with autoimmune or low-grade lymphoproliferative disorders. Adults or elderly patients are most commonly affected. The diagnosis is suspected when patients present with recurrent angioedema and low serum levels of C4 with normal levels of C3. Low levels of C1q and low C1 esterase inhibitor activity confirm the diagnosis. I...
متن کامل[Hereditary angioedema due to C1-esterase inhibitor deficiency].
The paper presents a case of family oedema by shortage of C1-esterase inhibitor, characterized by appearance at an early age (8 months), participation in some attacks of nasal mucous membrane, with nasal obstruction and sinusal manifestations and also the abnormally long period, up to 9 days, of some localized oedemas. The crises were absent during pregnancy. The study of four generations of th...
متن کاملC1-esterase inhibitor concentrate rescues erythrocytes from complement-mediated destruction in autoimmune hemolytic anemia.
In autoimmune hemolytic anemia (AIHA), autoantibody-mediated complement activation results in C3 deposition on RBCs and possibly the formation of the membrane attack complex cumulating in intravascular hemolysis.1-4 In case of acute signs of tissue hypoxia, life-saving transfusion with RBC units is required. However, recovery of RBC transfusions is inadequate because autoantibodies react with r...
