  • Patent number: 8489335
    Abstract: The invention relates to a method of diagnosing the presence and/or severity of a hepatic pathology and/or of monitoring the effectiveness of a curative treatment against a hepatic pathology in an individual, comprising the establishment of at least one non-invasive diagnostic score, in particular a diagnostic score for portal and septal fibrosis and/or an estimate score for the fibrosis area and/or an estimate score for the fractal dimension.

  • Publication number: 20120010824
    Abstract: The present invention relates to a non-invasive method for assessing liver fibrosis progression in an individual, said method comprising the steps of calculating the ratio of fibrosis level to cause duration and to a non-invasive method for assessing liver fibrosis progression in an individual, said method comprising the steps of measuring, at two different times t1 and t2, the fibrosis levels FL (t1) and FL (t2) and calculating the ratio FL (t2)?FL (t1) to (t2?t1) and to a non-invasive method for assessing if an individual is a slow, medium or fast fibroser.

  • Publication number: 20110313276
    Abstract: An in-vitro non-invasive method for quantifying the lesions of the liver of the patient with metabolic steatosis addressing a diagnostic target, i.e. fibrosis, steatosis and/or steato-hepatitis (NASH) and measuring at least one marker selected from the group consisting of biomarkers and possibly clinical markers and possibly scores, the biomarkers being selected from the group consisting of glycemia, AST (aspartate aminotransferase), ALT (alanine aminotransferase), AST/ALT, AST.

  • Publication number: 20110306849
    Abstract: This invention relates to method of diagnosing the presence and/or severity of a liver pathology and/or of monitoring the effectiveness of a curative treatment against a liver pathology in an individual, leading to a score, comprising the combination, of at least one blood test and of at least one data issued from a physical method of diagnosing liver fibrosis, said data being selected from the group consisting of medical imaging data and clinical measurements, said combination being performed through a mathematical function. This invention also relates to a method wherein the combination through a mathematical function, of at least one blood test and of at least one data issued from a physical method of diagnosing liver fibrosis, is performed at least twice and the at least two resulting scores are combined in an algorithm based on the diagnostic reliable intervals.

  • Publication number: 20070178443
    Abstract: The invention concerns a method for the detection of the presence and/or the severity of a liver disease in a patient comprising measuring in an isolated sample TIMP-1 (Tissue Inhibitor of Metalloproteinase I), A2M (a-2-macroglobulin), PLT (number of blood plateletes, PI (prothrombin index), optionally at least one additional parameter selected from the group consisting of urea and GGT (?-glutamyltranspeptidase) and optionally measuring at least one additional biochemical or clinical parameter and diagnosing the presence and/or severity of a liver disease based on the presence or measured levels of these parameters. The method can be used for monitoring therapeutic treatment of liver fibrosis and staging of liver fibrosis.

  • Publication number: 20070178442
    Abstract: A method for the detection of the presence and/or the severity of a liver disease in a patient comprising measuring in an isolated sample TIMP-1 (tissue inhibitor of metalloproteinase I), ferritin, at least one additional parameter selected from the group consisting of A2M (alpha-2-macroglobulin) and PI (prothrombin index) and optionally measuring at least one additional biochemical or clinical parameter and diagnosing the presence and/or severity of a liver disease based on the presence or measured levels of these parameters. The method can be used for monitoring therapeutic treatment of liver fibrosis and staging of liver fibrosis.
