Brief summary

This phase 2 trial is a single-site sequential, multiple assignment, randomized trial (SMART) to test and construct a high-quality adaptive intervention of essential amino acids (EAA) and/or Low Sugar Diet for children with metabolic dysfunction associated steatotic liver disease (MASLD) and increased cardiometabolic risk. The basis for the trial includes high-quality pilot data in both EAA for hepatic steatosis and a low sugar diet for hepatic steatosis. In the trial, children aged 11-17 years old will be eligible to participate if their BMI is greater than or equal to 95th% at baseline and hepatic steatosis is greater than or equal to 8% at baseline by Magnetic Resonance Imaging Proton Density Fat Fraction (MRI-PDFF) because this is the most common age group diagnosed with metabolic-dysfunction associated steatotic liver disease.

Detailed description

Metabolic-dysfunction associated steatotic liver disease is defined as the presence of abnormal hepatic stored triglycerides (hepatic steatosis), with one or more of 5 cardiometabolic factors (increased body mass index or waist circumference, hyperglycemia, hypertriglyceridemia, or low HDL) and no other chronic liver disease. Pediatric hepatic steatosis is central to long-term metabolic and cardiovascular health because of the relation of hepatic steatosis to the development of other major diseases. Hepatic steatosis limits the normal metabolic role of insulin and plays a key role in the future development of the metabolic syndrome, and is the strongest predictor for the development of type 2 diabetes.

Interventions

EAA supplement contains the following formulation: histidine, isoleucine, leucine, lysine, phenylalanine, threonine, and valine

The Low Sugar Diet uses the adapted and extended Social Cognitive Theory (SCT) guided low sugar intervention. The registered dietitian nutritionist (RDN) helps families to identify foods high in sugar and to identify acceptable replacements in order to remove foods and drinks high in free sugar from the home and replacement with low or no free sugar containing similar foods.

Masking description

Due to the nature of the treatment, it is not realistic to blind the treatment to either staff or patients and their caregivers. To mitigate the risk of bias associated with an unblinded study, all study team members will remain blinded to aggregate study results and only select members of the study team responsible for interim monitoring will have access to these data
