SummaryIn order to determine if there is a relationship between antiphospholipid antibodies and reduced free protein S levels, we evaluated 21 patients who had an antiphospholipid antibody but had neither a history of venous thromboembolism nor systemic lupus erythematosus (cases) and 55 matched controls, who did not have an antiphospholipid antibody, a history of thrombosis or systemic lupus erythematosus. Cases and controls had similar protein C and antithrombin levels. Six of 21 cases had reduced free protein S antigen levels, compared to 5 of 55 controls (x 2 = 5.823 p <0.025). In addition, the mean free protein S level was significantly lower in cases than in controls (0.30 ± 0.09 units vs 0.39 ± 0.13 units, p <0.01, two-tailed Student’s t-test). We conclude that antiphospholipid antibodies are associated with a significant decrease in free protein S levels, and that this acquired free protein S deficiency may contribute to the thrombotic diathesis seen in patients with antiphospholipid antibodies.

S Deficiency

Protein S deficiency is rare in systemic lupus erythematosus (SLE) and is generally associated with the presence of antiphospholipid (APL) antibodies. Lack of protein S can cause skin necrosis, but when it does it is generally in response to warfarin exposure. In this article, we describe the case of a patient who had not received warfarin and without APL antibodies who developed extensive skin necrosis due to protein S deficiency. It is important to investigate protein S deficiency in patients with lupus and extensive skin ulcers as it is a sign of arterial thrombosis and venous thromboembolism.

Loss Of Strength

A 19-year-old woman with a 6-year history, consisting of frequent falls and weakness due to loss of strength in the lower extremities. During the last 10 hours, she presented a sudden episode of left hemiplegia, deviation of the labial commissure to the right, dysarthria and four emetic episodes. She was diagnosed with an ischemic stroke caused by a deficiency of the S-protein and, in addition, a muscular dystrophy. This case report may indicate a relationship between muscular dystrophy and ischemic stroke caused by a protein S deficiency
