Clinical Trial Summary

Obesity is associated with a variety of co-morbidities. Children with obesity are more likely to have risk factors associated with cardiovascular diseases (CVD) and CVD risk markers (e.g. hypertension, elevated serum cholesterol, and type 2 diabetes mellitus), but also with organ specific pathologies such as a non-alcoholic fatty liver disease (NAFLD). A recent meta-analysis has shown that the prevalence of NAFLD in obese pediatric populations is approximately 35%, compared to approximately 8% in general pediatric population, making it a very important health threat in these populations. Successful pharmacological interventions to treat or prevent NASH are not yet available and so far only weight loss has clear benefits. However, it is well known that sustained weight-loss is difficult to achieve on the longer-term. The investigators recently demonstrated in mice that plant sterol and stanol ester consumption inhibited the development of liver inflammation. Moreover, Javanmardi et al. recently demonstrated in a population of adult NAFLD patients, that plasma concentrations of Alanine Transaminase (ALT) were reduced after daily plant sterol consumption (1.6 g/d) for 6 weeks. In this study, the investigators propose to evaluate the effect of consuming soft chews enriched with plant stanol esters (3 grams/day) on ALT concentrations in children with overweight or (morbid) obesity who are at risk of developing NAFLD, in a randomized, placebo-controlled, double blinded study with an intervention period and follow-up period of 6 months. 52 overweight and obese children with elevated ALT concentrations (>39 U/L for boys and >33 U/L for girls) will be included. All children will be randomly allocated to consume control or plant stanol ester enriched soft chews on a daily basis for a period of 6 months. After 12 months there will be an additional blood sample to evaluate whether the 6 months intervention is still effective.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in plasma ALT concentration at 6 and 12 months.	Plasma ALT (Alanine Aminotransferase) concentration is a laboratory parameter, measured in blood, reflecting possible presence of NAFLD. Concentrations below 26 U/L for boys, and below 22 U/L for girls, are considered normal. Concentrations above 39 U/L for boys, and above 33 U/L are considered to reflect presence of NAFLD.	Baseline, 6 months and 12 months
Secondary	Change in plasma AST and plasma CK-18 concentration at 6 and 12 months.	Aspartate Aminotransferase (AST) and cytokeratin-18 (CK-18) are laboratory parameters, measured in the participants blood in U/L, reflecting liver health.	Baseline, 6 months and 12 months
Secondary	Change in liver inflammation parameters at 6 and 12 months.	Cathepsin-D and acid phosphatase are laboratory parameters, measured in mg/L in the participants blood, reflecting liver inflammation.	Baseline, 6 months and 12 months
Secondary	Change in lipid metabolism parameters at 6 and 12 months.	Serum total cholesterol, HDL cholesterol, triacylglycerol (TAG) with correction for free glycerol and non-esterified fatty acids (NEFA) are laboratory parameters, measured in mmol/L in the participants blood, reflecting their lipid metabolism.	Baseline, 6 months and 12 months
Secondary	Change in lipid protein metabolism parameters at 6 and 12 months.	ApoA1 and apoB100 plasma concentrations are laboratory parameters, measured in g/L in the participants blood, reflective of the lipoprotein metabolism.	Baseline, 6 months and 12 months
Secondary	Change in plasma glucose concentration at 6 and 12 months.	Fasting glucose is a laboratory parameter, measured in mmol/L in the participants blood, reflecting glucose metabolism.	Baseline, 6 months and 12 months
Secondary	Change in plasma insulin concentration at 6 and 12 months.	Fasting insulin concentrations is a laboratory parameters, measured in mU/L in the participants blood, reflecting glucose metabolism.	Baseline, 6 months and 12 months
Secondary	Change in insulin sensitivity at 6 and 12 months.	Insulin sensitivity will be calculated using the HOMA-IR formula (homeostatis model) which is (fasting glucose*fasting insulin) /22,5. As HOMA-IR is a ratio, it does not have a unit.	Baseline, 6 months and 12 months
Secondary	Change in non-cholesterol sterol and oxy(phyto)sterol concentrations at 6 and 12 months.	A panel of non-cholesterol sterols, as surrogate markers for cholesterol absorption and synthesis will be measured in the participants blood.	Baseline, 6 months and 12 months
Secondary	Change in plasma inflammatory markers at 6 and 12 months.	Plasma concentrations of CRP and high sensitivity CRP will be measured in mg/L in the participants blood, to assess presence of low-grade inflammation in the body.	Baseline, 6 months and 12 months
Secondary	Change in ultrasonographic hepatorenal index (HRI) at 6 and 12 months.	HRI is measured during a conventional ultrasound of the liver, in which three close-up images of the liver and right kidney are made by a physician-researcher. HRI is calculated from these images by a pediatric radiologist, as the ratio of the hepatic brightness and the renal brightness (HRI = echogenicity of the liver/echogenicity of the kidney). The average of the three images is taken as the definite HRI, as a reflection of hepatic fat content.	Baseline, 6 months and 12 months
Secondary	Change in continuous Controlled Attenuation Parameter (CAP) at 6 and 12 months.	CAP is measured during a vibration controlled transient elastography of the liver, which is performed with a Fibroscan by a physician-researcher. The value is a reflection of hepatic fat content.	Baseline, 6 months and 12 months
