Patent number: 7604952Abstract: A method having clinically sufficient degree of diagnostic accuracy for detecting the presence of coronary artery disease in a human patient from the general population and for distinguishing between the stages of the disease in that patient is disclosed. The stages are, first, the non-acute stage, which is either asymptomatic coronary artery disease or stable angina, second, the acute stage known as unstable angina, and, third, the acute stage known as acute myocardial infarction. The diseased state (as opposed to the non-diseased state) is indicated by the clinically significant presence of a first marker in a sample from the patient. The presence of one of the two acute stages, unstable angina or acute myocardial infarction, is indicated by the clinically significant presence of a second marker in a sample from the patient. The presence of the more severe acute stage known as acute myocardial infarction is indicated by the clinically significant presence of a third marker in a sample from the patient.Type: GrantFiled: January 16, 2007Date of Patent: October 20, 2009Assignee: Leuven Research & Development VZWInventors: Paul N. Holvoet, Désiré J. Collen

Patent number: 5336495Abstract: The present invention relates to the use of staphylokinase for the preparation of a pharmaceutical composition for treating arterial thrombosis, such as e.g. myocardial infarction. It is demonstrated that staphylokinase can be particularly useful as a thrombolytic agent for the lysis of platelet-rich clots. Furthermore it is demonstrated that staphylokinase, unlike streptokinase, does not induce antibody induction upon repeated administration.Type: GrantFiled: July 14, 1993Date of Patent: August 9, 1994Assignees: Leuven Research & Development vcw, Desire J.

Patent number: 5174994Abstract: Plasminogen activators of the tissue-type and plasminogen activators of the urokinase-type appear to have a synergistic action in vivo when administered together as thrombolytic agents. Use in pharmaceutical compositions and in methods for the preparation and use thereof are set forth.Type: GrantFiled: July 21, 1989Date of Patent: December 29, 1992Assignee: Leuven Research & Development VZWInventor: Desire J. Collen

Patent number: 4216291Abstract: A thrombosis test is based on the presence of specific, newly-found, enzyme-inhibitor complexes (such as plasmin-antiplasmin, plasmin-.alpha..sub.2 -macroglobulin, thrombin-antithrombin-III) in blood samples having an activated blood coagulation and/or fibrinolytic system. The test is immunochemical and uses a purified antiserum which has been generated against the enzyme-inhibitor complex. The antiserum is purified by incubating the antiserum with plasminogen and fresh blood plasma and isolating a gamma globulin fraction containing antibodies specific to the enzyme-inhibitor complex. A reagent for the test is prepared by contacting a blood cell suspension or a latex of particles of synthetic resin with the purified antiserum to obtain a suspension or latex in which antibodies from the antiserum are present on the surface of the cells or particles.Type: GrantFiled: October 10, 1978Date of Patent: August 5, 1980Assignee: Leuven Research & Development V.Z.W.Inventor: Desire J. Collen

Patent number: 4202872Abstract: A test for determining the anti-coagulation level in blood samples is based on ascertaining the presence of heparin-antithrombin-III complex therein. This may be done with the aid of antibodies against thrombin-antithrombin-III complex, such antibodies being used e.g. in the form of a latex reagent or a bloodcell reagent.Type: GrantFiled: March 1, 1977Date of Patent: May 13, 1980Assignee: Leuven Research & Development V.Z.W.Inventor: Desire J.

Patent number: 4180437Abstract: Antiserum which has been generated against an enzyme-inhibitor-complex is purified by immunoprecipitating a freshly generated antiserum with fresh human bloodplasma to form a precipitate and a fluid, and subjecting the fluid to chromatographic separation over an insolubilized enzyme-inhibitor complex against which the antiserum has been generated. A reagent for immunochemical assay is prepared by contacting the purified antiserum with red bloodcells or synthetic resin particles to obtain on the surface of the red bloodcells or synthetic resin particles antibodies from the antiserum. In a diagnosis test, blood plasma is contacted with the purified antiserum and with red bloodcells or synthetic resin particles which bear the enzyme-inhibitor complex used to prepare the antiserum, and whether or not agglutination occurs is ascertained.Type: GrantFiled: March 1, 1977Date of Patent: December 25, 1979Assignee: Leuven Research & Development V.Z.W.Inventor: Desire J.
