Abstract
BACKGROUND:
Nonalcoholic-fatty-liver-disease/nonalcoholic steatohepatitis (NAFLD/NASH) is expected to become the leading liver disease worldwide. Typical liver-related complications are fibrosis, cirrhosis, and the development of hepatocellular cancer (HCC) with the need for liver transplantation. Up to now there is no approved pharmacotherapy. Indeed, this might be due to the complexity of this disease. While the cheapest therapeutic approach is still a lifestyle change leading to weight loss, the proportion of people achieving sufficient weight reduction without additional support is low. Newly developed drugs are expensive and lack a breakthrough in therapeutic success. One reason might be that drugs developed often derive from murine models. Unfortunately, there is little overlap between genes in human and mice that are responsible for the development of NAFLD/NASH. This review aims at summarizing latest developments as well as stress again that more translational research is necessary.
SUMMARY:
Therapy of NAFLD/NASH is easy and very complex at the same time, as the current main target is weight reduction. Since this is in fact not easily achieved and maintained by many affected individuals, pharmacotherapy to halt the progression of NAFLD/NASH is urgently warranted. More translational studies are needed to understand the metabolic mechanisms and interactions between the liver, gut, oxidative stress and the processes leading to NAFLD progression and HCC development, even in the absence of cirrhosis.
