  Purpose

Non-alcoholic fatty liver disease (NAFLD) has reached epidemic proportions and is rapidly becoming the one of most common causes of chronic liver disease in children. The pathogenesis of NAFLD is generally considered the result of a series of liver injuries, commonly referred as "multi-hit" hypothesis. Insulin resistance and increased serum levels of free fatty acids (FFAs) are considered the main primary hits that lead to the excessive lipid accumulation in hepatocytes resulting in steatosis.

Has been reported that a diet rich in high-viscosity fiber improves glycemic control and lipid profile, suggesting a therapeutic potential role in the treatment of NAFLD.

Aim of this study is to evaluate the efficacy and tolerability of glucomannan in children affected by non alcoholic fatty liver disease.

Further study details as provided by Valerio Nobili, Bambino Gesù Hospital and Research Institute:

Primary Outcome Measures:
  • Change from Baseline in lipid profile [ Time Frame: 6,12,18,24 months ]
    Evaluation of tryglicerides, total and LDL colesterol levels

  • Change from baseline in glycemic homeostasis [ Time Frame: 6,12,18,24 months ]
    glycemic homeostesis will be evaluated through glycemia and insulinemia basal levels and after oral glucose tolerance test


Secondary Outcome Measures:
  • liver enzymes [ Time Frame: 6,12,18,24 months ]
    evaluation of liver function test


Enrollment: 66
Study Start Date: June 2011
Study Completion Date: December 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: glucomannan Dietary Supplement: glucomannan
glucomannan is administered at dosage of 5g/day in form of biscuits (6 biscuits/day)
Placebo Comparator: placebo Behavioral: lifestyle intervention
