Impact of Artificial Intelligence Algorithm-driven Versus Standard Lifestyle Intervention in Non-Alcoholic Fatty Liver Disease - A Multicenter, Randomized, Open-label, Controlled Trial

Starting soon · Not applicable

Conditions studied: Non Alcoholic Fatty Liver Disease

In brief

Now considered as a major public health challenge, non-alcoholic fatty liver disease (NAFLD) is rapidly rising as a major cause of end-stage liver disease. NAFLD encompasses a spectrum of conditions, ranging from steatosis, defined by excessive liver fat deposition, to Non-Alcoholic Steato-Hepatitis (NASH), an inflammatory and fibrotic stage which promotes severe complications such as cirrhosis and hepatocellular carcinoma. Although several drugs are currently under clinical development to limit inflammation and fibrosis processes, clinical evidence and previous studies support the role of lifestyle intervention (dietary modifications and exercise) as a cornerstone for NAFLD management. Indeed, insulin resistance is a key pathogenic trigger of the disease and patients with NAFLD are frequently obese and/or have type 2 diabetes. Therefore, lifestyle intervention should be implemented as early as possible in the disease course, from the first evidence of steatosis. Designing lifestyle interventions with good efficacy and sustainability for patients with NAFLD, and with acceptable medico-economic costs, is thus urgently needed. However, the optimal way to implement such lifestyle modification programs remains unclear. Technological innovations in health-monitoring devices recently made it possible to propose disruptive lifestyle interventions, but the value of such strategies has not been addressed in NAFLD so far.
