  • Patent number: 11231422
    Abstract: Plasma levels of different sub-populations of microvesicles (endothelial, leukocyte, platelet and hepatocyte) were measured by flow cytometry or ELISA/filtration on blood samples from 125 patients with cirrhosis, for which 36 of them were diagnosed with HCC at inclusion. The inventors show that the levels of microvesicles of endothelial origin (CD62E+) could predict the occurrence of HCC in patients with cirrhosis. Therefore the present invention relates to a method for determining whether a patient suffering from cirrhosis is at risk of having or developing hepatocellular carcinoma comprising determining the level of endothelial-derived microvesicles (e.g. by flow cytometry) in a blood sample obtained from the patient.

  • Publication number: 20200225247
    Abstract: Following a prospective clinical study that includes 242 patients, the inventors show that hepatocyte-derived MV levels predicted transplantation-free survival at 6 months in univariate analysis. In multivariate analysis, this association was shown to be independent of Child-Pugh and of MELD score. Thus the present invention thus relates to a method of predicting the transplantation-free survival time of a patient suffering from cirrhosis comprising determining the level of hepatocyte-derived microvesicles (e.g. by an ELISA assay) in a blood sample obtained from the patient.
