Safety and Effectiveness of tPA in Intra-Abdominal Abscesses
Summary
To determine if instillation of tissue plasminogen activator into a percutaneously drained intraabdominal abscess cavity results in faster resolution of the abscess compared to normal standard of care.

Medical and Biotech [MESH] Definitions
Anistreplase
An acylated inactive complex of streptokinase and human lysine-plasminogen. After injection, the acyl group is slowly hydrolyzed, producing an activator that converts plasminogen to plasmin, thereby initiating fibrinolysis. Its half-life is about 90 minutes compared to 5 minutes for TPA; (TISSUE PLASMINOGEN ACTIVATOR); 16 minutes for UROKINASE-TYPE PLASMINOGEN ACTIVATOR and 23 minutes for STREPTOKINASE. If treatment is initiated within 3 hours of onset of symptoms for acute myocardial infarction, the drug preserves myocardial tissue and left ventricular function and increases coronary artery patency. Bleeding complications are similar to other thrombolytic agents.
Tissue Plasminogen Activator
A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to FIBRINOLYSIN. It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.
Receptors, Urokinase Plasminogen Activator
An extracellular receptor specific for UROKINASE-TYPE PLASMINOGEN ACTIVATOR. It is attached to the cell membrane via a GLYCOSYLPHOSPHATIDYLINOSITOL LINKAGE and plays a role in the co-localization of urokinase-type plasminogen activator with PLASMINOGEN.
Plasminogen Activator Inhibitor 2
Member of the serpin family of proteins. It inhibits both the tissue-type and urokinase-type plasminogen activators.
Plasminogen Activator Inhibitor 1
A member of the serpin family of proteins. It inhibits both the tissue-type and urokinase-type plasminogen activators.
