Recurrent venous thrombosis in a patient with chronic lymphocytic leukemia and acquired protein S deficiency

Haematologia (Budap). 2000;30(1):51-4. doi: 10.1163/15685590051129896.

Abstract

A patient with chronic lymphocytic leukemia and an undetectable plasma level of protein S (PS), associated with recurrent venous thrombosis, is described. The laboratory investigation revealed the concomitant presence of an inhibitor directed to PS and a monoclonal protein in the patient's plasma. After treatment with prednisone and cyclophosphamide both the inhibitor to PS and the monoclonal component disappeared.
