Patients with overlapping nonalcoholic fatty liver disease (NAFLD) and alcohol-related liver disease (ALD) are commonly excluded from clinical studies. This webinar will review the overlapping pathophysiology, shared genetic-epigenetic factors and the reciprocal interaction of these factors to determine liver disease prognosis. In particular, we will discuss the data regarding alcohol consumption in NAFLD and obesity/metabolic syndrome in ALD.
