Synergistic combination of biomarkers for detecting and assessing hepatic fibrosis
The application relates to hepatic fibrosis, specifically to hepatic fibrosis that may appear in a patient infected with one or more hepatitis viruses and/or who is suffering from hepatitis, specifically chronic hepatitis. The application provides methods and means for determining the stage (or degree) of hepatic fibrosis of such a patient. Specifically, the methods and means of the application make it possible to determine whether or not the stage (or degree) of hepatic fibrosis of the patient has exceeded the stage of light fibrosis. The methods and means of the invention use a combination of biomarkers such as, in particular, the CXCL10 protein and hyaluronic acid (HA).
1. An article of manufacture for the multiplex detection of molecules contained in acellular form in a biological fluid comprising a solid support to which the ligands of said molecules are attached, in which the ligands of said molecules comprise:
a first protein that specifically binds to hyaluronic acid (HA); and
a second protein that specifically binds to C-X-C motif chemokine ligand 10 (CXCL10).
2. The article of manufacture according to claim 1 , in which said solid support is a plate or microplate with wells, a chip made of silicon, a glass capillary, a glass slide, magnetic beads, or a membrane.
3. The article of manufacture according to claim 1 , wherein the first protein is an antibody that binds to HA and the second protein is an antibody that binds to CXCL10.
4. A composition for the multiplex detection of molecules contained in acellular form in a biological fluid, comprising a mixture of the ligands of said molecules, in which the ligands of said molecules comprise:
a first protein that specifically binds to HA and bears a first detection marker; and
a second protein that specifically binds to CXCL10 and bears a second detection marker;
in which said first detection marker is different from said second detection marker.
5. The composition according to claim 4 , wherein the first protein is an antibody that binds to HA and the second protein is an antibody that binds to CXCL10.
6. A kit comprising nucleic acids that bind specifically to one or more hepatitis viruses, the kit further comprising ligands that bind to molecules contained in acellular form in a biological fluid, said ligands contained in the kit in a combined preparation for simultaneous use, said ligands comprise:
a first protein that specifically binds to HA and bears a first detection marker; and
a second protein that specifically binds to CXCL10 and bears a second detection marker;
in which said second detection marker is different from said first detection marker.
7. The kit according to claim 6 , further comprising an article of manufacture for the multiplex detection of molecules contained in acellular form in a biological fluid, the article of manufacture comprising a solid support to which the ligands of said molecules are attached.
8. The kit according to claim 6 , further comprising an article of manufacture for multiplex detection of molecules contained in acellular form in a biological fluid, the article of manufacture comprising a solid support to which the ligands of said molecules are attached, wherein the solid support is a plate or microplate with wells, a chip made of silicon, a glass capillary, a glass slide, magnetic beads, or a membrane.
9. The kit according to claim 6 , wherein the first protein is an antibody that binds to HA and the second protein is an antibody that binds to CXCL10.
