Urokinase versus streptokinase in local thrombolysis. 1987

A van Breda, and B T Katzen, and A S Deutsch

In a retrospective analysis, the efficacy of lysis, the degree of systemic thrombolytic effect, and the rate of complications during local thrombolytic therapy with either streptokinase (SK) or urokinase (UK) were compared in 47 patients. There were 24 infusions of each agent; one patient in the UK group received two infusions. The overall efficacy of lysis was better in the UK-treated group (80% vs. 63%). The UK group had a lower frequency of systemic thrombolytic effect and of bleeding complications. SK antibody titers were measured in all patients who received infusions. Patients with high titers who were treated with SK responded poorly (20% lysis); patients with low titers responded at a rate equal to that of UK-treated patients. Three patients with high titers of SK antibodies did not respond to SK, but subsequent successful lysis did occur with UK. In conclusion, UK is believed to be preferable to SK for local thrombolytic therapy due to increased efficacy of lysis and decreased rate of systemic fibrinolytic effect and bleeding complications.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random

D000906	Antibodies	Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
D001157	Arterial Occlusive Diseases	Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D013300	Streptokinase	Streptococcal fibrinolysin . An enzyme produced by hemolytic streptococci. It hydrolyzes amide linkages and serves as an activator of plasminogen. It is used in thrombolytic therapy and is used also in mixtures with streptodornase (STREPTODORNASE AND STREPTOKINASE). EC 3.4.-.
