Brief Summary: Non-alcoholic fatty liver disease NAFLD estimated to be 17 prevalent in France can lead to non-alcoholic steatohepatitis NASH which in turn can progress to fibrosis the ultimate stage of which is cirrhosis a major cause of liver transplantation The prevalence of NASH is increasing worldwide along with that of type 2 diabetes and obesity Significant liver fibrosis is estimated to affect at least 26 of the adult population in France

The prognosis of patients with NASH is directly linked to the stage of liver fibrosis determined by biopsy and these biopsies must now be repeated to assess the effect of treatments Hepatic fibrosis is traditionally classified into five stages from the absence of fibrosis F0 to severe cirrhosis F4 and passage from one stage to another is considered to demonstrate significant variation likely to impact prognosis

However liver biopsy is painful It can only analyze a very small proportion of liver volume 150000 whereas the distribution of fibrosis is generally heterogeneous Above all biopsy is not devoid of risks primarily hemorrhage which can sometimes be severe or even fatal

In line with current recommendations clinical-biological algorithms as well as ultrasound elastography or MRI are used to assess the risk of fibrosis and the value of a liver biopsy Generally speaking these tests have the advantage of very good negative predictive values making it possible to exclude the possibility of significant fibrosis in a large proportion of patients However their positive predictive values are weaker even when these tests are combined Above all they do not allow us to follow the evolution of the fibrosis stage over time This is why liver biopsies remain indispensable for determining the stage and severity of hepatic fibrosis and monitoring its evolution It is therefore essential to develop more precise non-invasive methods for accurately assessing the extent of liver fibrosis This is the objective of the FreSH national cohort which uses conventional biological techniques and in which our patients will also be included

The hypothesis behind this initial pilot study is that 68Ga-FAPI-46 PETCT imaging which targets fibroblast activating protein FAP could provide a precise assessment of the severity and stages of liver fibrosis as well as its distribution throughout the liver volume and could ultimately be a useful tool for non-invasive monitoring of patients undergoing treatment This technique has already been validated for the detection of numerous cancers including hepatocarcinomas and is capable of assessing renal fibrosis pilot study with 15 patients with a good correlation to biopsy and a direct link to glomerular filtration rate

Targeted receptor FAP data also strongly support our hypothesis

FAP expression is negligible in healthy livers and proportional to the degree of fibrosis in pathological livers
Low plasma FAP concentrations rule out the hypothesis of hepatic fibrosis PAF inhibitors also represent a very promising avenue of therapeutic research in NASH

The HEFITEP study will assess for the first time the discriminative power of 68Ga-FAPI-46 PETCT for grading liver fibrosis with reference to centrally analyzed liver biopsy in patients biopsied for suspected or proven non-alcoholic steatohepatitis NASH
