Protein S antibodies in acquired protein S deficiencies.

stroke in an infant; its association with antiphospholipid antibody and acquired protein c and s deficiencies

we present the first reported case of antiphospholipid syndrome with stroke in an iranian boy (7-month-old) who had two ischemic strokes within a period of 2 months. serum anticardiolipid antibody was positive and the patient had low levels of protein s and c. this case emphasizes the importance of antiphospholipid antibody in children with unexplained ischemic stroke.

Deficiencies of natural anticoagulants, protein C, protein S, and antithrombin.

Y ou or a family member may have developed a blood clot in one of the deep veins in the body (ie, a deep vein thrombosis, or DVT) or had a blood clot that traveled to the lungs (ie, a pulmonary embolism, or PE). As part of your medical care, your doctor may have evaluated you for conditions that may have contributed to developing a blood clot. Thrombophilia is a condition in which there is an i...

Thrombosis in inherited deficiencies of antithrombin, protein C, and protein S.

The coagulation cascade can be pictured as a series of reactions in which a zymogen, a cofactor, and a converting enzyme interact to form a multimolecular complex on a natural surface. In each case, the four reactants must be present if the conversion of a zymogen to the corresponding serine protease is to take place at any significant rate. The principal natural anticoagulant systems that are ...
