Severe thrombotic tendency associated with a type I plasminogen deficiency.
We report a 45-year-old female patient with recurrent spontaneous deep vein thrombosis associated with an isolated hypoplasminogenemia (plasminogen activity and antigen level of 42% and 37%, respectively). The plasminogen molecule was normal as demonstrated by a normal activation by tissue plasminogen activator, electrophoretic mobility on crossed immunoelectrophoresis, molecular weight, and binding to lysine sepharose. All other hemostatic parameters predisposing to recurrent thrombosis were normal. A stimulation test with desmopressin acetate (DDAVP) showed a normal plasma rise of both tissue plasminogen activator and factor VIIIR:WF. This isolated plasminogen deficiency apparently is due to a decreased synthesis of a normal plasminogen molecule and is associated with a severe thrombotic tendency.
