Plasminogen activator inhibitor type 1 deficiency.

Serum Level of Plasminogen Activator Inhibitor Type-1 in Addicted Patients ‎with Coronary Artery Disease

Background: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction with PAI-1 level. Opium addiction i...

Type 1 plasminogen activator inhibitor deficiency aggravates the course of experimental glomerulonephritis through overactivation of transforming growth factor beta.

Type 1 plasminogen activator inhibitor (PAI-1) is the primary inhibitor of tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA). Whereas PAI-1 is not expressed in normal kidneys, it is strongly induced in glomerular diseases and thus could promote the local accumulation of fibrin. To study the role of PAI-1 in the development of inflammatory glomerular injury, ...

Methyltetrahydrofolate Reductase C677T Mutation and 4G/5G Plasminogen Activator Inhibitor-1 Polymorphism in a Child with Deep Vein Thrombosis

Accelerated thrombus lysis in the blood of plasminogen activator inhibitor deficient mice is inhibited by PAI-1 with a very long half-life.

Patients with defective plasminogen activator inhibitor protein (PAI-1) or with PAI-1 deficiency can experience hemorrhage as a result of a hyperfibrinolysis. In these patients, a normal thrombus forms, but endogenous lysis is unchecked as tissue plasminogen activator is unopposed. Treatment includes anti-fibrinolytic agents, including oral tranexamic acid. Another treatment option is the admin...

Oral management of a patient with a plasminogen activator inhibitor (PAI-1) deficiency: case report.

Plasminogen activator inhibitor-1 (PAI-1) deficiency causes a rare bleeding disorder by allowing excessive fibrinolysis to occur. Knowledge of the specific type and severity of the bleeding disorder is crucial in planning a safe and appropriate treatment sequence in conjunction with a hemophilia team. This article reports the oral management of a 9-year-old female with PAI-1 inhibitor deficienc...

A Lifelong Bleeding Disorder Associated With a Deficiency of Plasminogen Activator Inhibitor Type

A 36-year-old patient was investigated for a lifelong history of epistaxis and delayed bleeding after minor surgeries. Deficiencies or abnormalities of the coagulation system, of platelet function, or of factor Xlll and a-2-antiplasmin were excluded. Consistently, however, over a period of 7 years, a high basal euglobulin fibrinolytic activity was observed that was characterized by a high tissu...
