Abstract

The invention provides a method of diagnosing Non-Alcoholic Steatohepatitis (NASH) and/or the hepatic fibrosis status of a subject, especially a subject afflicted with Non-alcoholic fatty liver disease (NAFLD) or NASH, based on the level of only three or more particular biomarkers. The invention further provides a kit suitable for performing said method and the use of said method and methods of treating patients diagnosed in accordance with the disclosed methods.

Claims (154)

1 . A kit for diagnosing NASH and/or the hepatic fibrosis status of a subject comprising:

(i) antibodies for determining, in a blood, plasma, serum, urine or cerebrospinal fluid sample obtained from a subject, levels of at least three biomarkers, said at least three biomarkers being a pro-inflammatory cytokine, a chemokine and a glycosaminoglycan contributing to cell-adhesion and tissue modeling, wherein:

(a) the pro-inflammatory cytokine is IL-8;

(b) the chemokine is CXCL10;

(c) the glycosaminoglycan contributing to cell-adhesion and tissue modeling is hyaluronic acid; and

(ii) instructions, said instructions disclosing:

contacting said sample with antibodies that bind to said at least three biomarkers and determining the levels of said IL-8, CXCL10 and HA in said sample;

calculating a value for f 1(NASH) and/or f 1(fibrosis) , wherein

and

when f 1(NASH) >0.4997, the subject is diagnosed with NASH and when f 1(NASH) ≤0.4997, the subject is diagnosed with non-alcoholic fatty liver (NAFL) and when f 1(fibrosis) >0.1953, the subject is diagnosed with advanced liver fibrosis and when f 1(fibrosis) ≤0.1953, the subject is diagnosed with early-moderate liver fibrosis.

2 . The kit of claim 1 , further comprising antibodies for determining, in a sample obtained from the subject, the levels of one or more of ghrelin, haptoglobin and pre-HP2.

3 . The kit of claim 1 , wherein:

(i) the kit comprises labeled antibodies that bind the biomarkers and the measuring the levels of biomarkers is done by ELISA, Luminex multiplex technology, microarray or point of care testing; and/or

(ii) the sample is a plasma or serum blood.

4 . The kit according to claim 3 , wherein the antibodies are fluorescently labeled.

5 . The kit according to claim 2 , wherein the antibodies are fluorescently labeled.
