Preoperative predictors of postsurgical adhesion formation and the Prevention of Adhesions with Plasminogen Activator (PAPA-study): Results of a clinical pilot study

Objective: To identify predictors of postsurgical adhesion formation in peritoneal fluid and plasma, and assess efficacy and safety of reteplase (recombinant plasminogen activator [r-PA]). Design: Prospective randomized study. Setting: University Medical Center. Patient(s): Twenty-six abdominal myomectomy patients with early second-look...

Comparison of a transdermal contraceptive patch vs. oral contraceptives on hemostasis variables

Purpose: The aim of this study was to compare effects of the transdermal contraceptive patch, a desogestrel/ethinyl estradiol (EE)-containing, monophasic combination oral contraceptive (COC) and a levonorgestrel/EE-containing, triphasic COC on hemostasis variables. Study Design: This was a randomized, open-label study of 104 young women who...

Development of a new test for the global fibrinolytic capacity in whole blood

Background: The development of global tests for the fibrinolytic capacity in blood is hampered by the low base-line fibrinolytic activity in blood, by the involvement of both plasmatic components and blood cells in the fibrinolytic system and by the loss of fibrinolytic activity as a result of the action of plasminogen activator inhibitor-1 (PAI...

A neoantigenic determinant in the D-dimer fragment of fibrin

Monoclonal antibody (mAb) III-3b binds D-dimer with Kd = 1.4 × 10-10 M without cross-reaction with fibrin(ogen). The epitope for this mAb is in Bβ134-190, presumably in Bβ155-160. The latter site is buried in the coiled coil structure of fibrin(ogen) but it is exposed as a neoantigenic determinant in D-dimer upon plasmic lysis of fibrin. mAb III...

Reduced activity of TAFI (thrombin-activatable fibrinolysis inhibitor) in acute promyelocytic leukaemia

Acute promyelocytic leukaemia (APL) is a disease that is distinguished from other leukaemias by the high potential for early haemorrhagic death. Several processes are involved, such as disseminated intravascular coagulation and hyperfibrinolysis. Recently, TAFI (thrombin-activatable fibrinolysis inhibitor) was identified as a link between...

Determination of fibrin(ogen) degradation products (FDP) in plasma, using a monoclonal antibody

Activation of plasminogen by tissue activator is increased specifically in the presence of certain soluble fibrin(ogen) fragments

Tissue activator-mediated plasminogen activation is potentiated both by fibrin and by some soluble fibrin(ogen) fragments. The potentiating effect of the different fragments decreases in the order fibrin monomer > D-dimer > Y > D EGTA > Dcate > X. Fibrinogen and the fragments Ecate, E EGTA and E fibrin have almost no effect. The existence of a...
