title: [Severe acquired protein S deficiency with thrombophlebitis after febrile infection in a 7-year-old girl].
abstract: The importance of the anticoagulant properties of protein S is illustrated by the high incidence of thromboembolic events in individuals with protein S-deficiency. A 7 year old girl was hospitalized with purpura-like bruises and lesions on both thighs after she had suffered from febrile infection. A subsequently developing thrombosis of the left V. femoralis was treated successfully with urokinase. Haemostaseological investigations showed no signs of disseminated intravascular coagulation. However, isolated severe degradation or all protein S-components due to the presence of a circulating autoantibody to protein S was found. After several months the antibody was detectable not any more, activity and antigens of protein S were normal.
