Nonalcoholic fatty liver disease (NAFLD) is being recognized as one of the most prevalent causes of chronic liver disease worldwide. The current strategy proposed by the EASL/EASO/EASD European guidelines for the screening of nonalcoholic fatty liver disease (NAFLD) in high-risk population such as type 2 diabetes and patients with obesity leads to an over-referral in hepatology clinics. The proposed study will investigate the optimal strategy for the screening of NAFLD-related advanced fibrosis in patients at high risk of fibrotic NAFLD, such as patients with T2DM or obesity by maximizing the positive predictive value (PPV) using non-invasive blood and elastography-based biomarkers in endocrinology/diabetology clinics in order to reduce the over-referral to hepatology clinics.

Inclusion Criteria:

• Patient aged between 40 and 80 years old,
• Patients with diagnosis of T2DM* or obesity (defined according to World Health Organization as a BMI≥ 30 kg/m2)
• Patient with hepatic steatosis determined by conventional abdominal ultrasound as defined by the EASL/EASO/EASD European guidelines.
• Patient who agrees to be included in the study and who signs the informed consent form,
• Patient affiliated to a healthcare insurance plan.

Exclusion Criteria:

• Evidence of other causes of chronic liver disease:
• History of ingestion of medications known to produce steatosis in the previous 6 months.
• Evidence of cirrhosis or previously known cirrhosis based on the results from previous liver biopsy or history of portal hypertension presented by ascites, hepatic encephalopathy or varices
• Presence of regular and/or excessive use of alcohol (defined as >30g/day for males and >15g/day for females) for a period longer than 2 years at any times in the last 10 years
• The subject is a pregnant or nursing female
• Life expectancy less than 5 years
• History of known HIV infection
• History of type 1 diabete
• BMI ≥ 40 kg/m2
• Mentally unbalanced patients, under supervision or guardianship,
• Patient deprived of liberty,
• Patient who does not understand French/ is unable to give consent,
• Patient already included in a trial who may interfere with the study or in a period of exclusion following participation in a previous study.
