Resveratrol for the Treatment of Non Alcoholic Fatty Liver Disease and Insulin Resistance in Overweight Adolescents

Safety and Efficacy of Resveratrol for the Treatment of Non-Alcoholic Fatty Liver Disease and Associated Insulin Resistance in Overweight and Obese Adolescents

The current project is designed as a 30-day pilot trial to demonstrate the safety and tolerability of resveratrol therapy in overweight adolescents to decrease liver fat, and improve insulin sensitivity to prevent type 2 diabetes.

Study Overview

• Status: Completed
• Conditions: NAFLD; TYPE 2 DIABETES; METABOLIC SYNDROME
• Intervention / Treatment: Dietary supplement: Resveratrol; Dietary supplement: Placebo

Detailed Description

Pilot study of 10 overweight or obese children with MRS determined fatty liver randomized to resveratrol or placebo. Primary outcome measures include change in liver triglyceride content as determined by MRS and improvement in insulin resistance as determined by the area under the curve of glucose excursion during a 75 gram oral glucose tolerance test.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Resveratrol; Intervention: Resveratrol Oral supplementation of resveratrol (ResVida) 75 mg twice daily (with breakfast and dinner) for a total daily dose of 150 mg for the duration of 30 days.	Dietary supplement: Resveratrol; All adolescents will receive standardized lifestyle counselling at enrolment designed and disseminated by a registered dietitian as well as a licensed physiotherapist who both have experience working with overweight adolescents. The lifestyle component will be goal-based and tailored to each participant. The overall content and messaging will be consistent for all participants with nutritional recommendations based on Canada Food Guide and physical activity counselling aligning with the Healthy Active Living Recommendations of the Canadian Pediatric Society and Health Canada's Physical Activity Guidelines.; Other Names: ResVida (Registered Trademark of DSM)
Placebo Comparator: Placebo; Intervention: Placebo Control Oral supplementation of placebo twice daily (with breakfast and dinner) for a total duration of 30 days.	Dietary supplement: Placebo; All adolescents will receive standardized lifestyle counselling at enrolment designed and disseminated by a registered dietitian as well as a licensed physiotherapist who both have experience working with overweight adolescents. The lifestyle component will be goal-based and tailored to each participant.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Safety/ Adverse Event Outcome	Primary Side effect profile determined by participant interview and serum biochemistry. Side effect profile determined by serum biochemistry: AST, ALT, total and conjugated bilirubin, Creatinine, sodium, potassium, calcium, magnesium, chloride and TC02, haemoglobin, haematocrit, white blood cell and platelet counts, erythrocytes, and fasting lipid levels (total cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides). Fasting glucose and insulin levels. PT/INR and PTT levels.; Vital signs	One week

Sixty-four spectra will be acquired and averaged for the determination of intracellular water and lipid content. LCModel software will be used to isolate and quantify lipid and water peaks. Hepatic steatosis will be defined as hepatic triglyceride content of >.5% fat/water.	Week 4
