Administration of Deuterated water: A blood sample will be taken in the morning after an overnight fast and after consuming deuterated water (2H2O) (3 g/kg body water) the evening before the study day to achieve a plasma water enrichment of 0.3% for the measurement of DNL
Study summary
The main objective is to study and validate a new approach for NASH and liver fibrosis diagnosis and personalized follow-up based on monocyte biomarkers and plasma metabolites. The investigators will assess if PLIN2 and RAB14 can be used not only to identify subjects with NASH and advanced fibrosis but also for monitoring the effect of treatment alone or in combination with other metabolic parameters

Primary outcome measure(s)
Identification of NASH and Advanced Fibrosis, using PLIN2 and RAB14, in 288 patients undergoing bariatric surgery — 18 months PLIN2 and RAB14 will be assessed by flow cytometry in monocytes stored at -80°C from all patients who participated in the BRAVES RCT (288 Subjects). PLIN2 and RAB14 median fluorescent intensity will be used to identify subjects with NASH (NAS \>=4) and advanced fibrosis (stage\>=2).
