Focused Power Ultrasound Mediated Inferior Perirenal Adipose Tissue Modification Therapy for Non-Alcoholic Fatty Liver Disease (PARADISE-NAFLD)

This randomized, blinded, sham-control trial aims to evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for non-alcoholic fatty liver disease.

Visceral adiposity is closely related to the incidence of non-alcoholic fatty liver disease (NAFLD), and it is also directly associated with liver inflammation and fibrosis. Visceral adiposity, via its unique location and enhanced lipolytic activity, releases toxic free fatty acids, which are delivered in high concentrations directly to the liver and lead to the accumulation and storage of hepatic fat. Furthermore, it has been recognized as an important endocrine organ, and a variety of factors secreted by visceral adiposity may lead to an increased risk of NAFLD. Peri-renal fat is a special type of visceral adiposity which is different from other type of visceral fat in histology, physiology, and functions. The position of peri-renal fat is more stable than other visceral fat. The investigators found that prophylactic perirenal adipose tissue ablation can prevent the development of NAFLD in mice induced by high fat diets, and also this novel focused power ultrasound can rapidly and efficiently promote the peri-renal adipose tissue fibrosis in the model of swine. Moreover, the investigators performed a single arm, small sample study to investigate the feasibility of the novel focused power ultrasound to modify the inferior peri-renal adipose tissue in NAFLD participants, showing that this kind of method was feasible and safe. In this study, the investigators aim to further evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for NAFLD.
