Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the effects of Rice Bran Arabinoxylan Compound (RBAC) on outcome variables in persons with non-alcoholic fatty liver disease (NAFLD). This nutritional supplement is made from a water soluble extract of rice bran that has been partially hydrolyzed by the action of a natural enzyme complex extracted from Shiitake mushroom.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to investigate the effects of Rice Bran Arabinoxylan Compound (RBAC) on outcome variables in persons with non-alcoholic fatty liver disease (NAFLD). This nutritional supplement is made from a water soluble extract of rice bran that has been partially hydrolyzed by the action of a natural enzyme complex extracted from Shiitake mushroom. Given that these micronutrients may be important for regulating the immune system, investigators will investigate the impact of RBAC on the following variables among 20 adults (18+ years of age and over) diagnosed with NAFLD:

1. albumin
2. 4-hydroxynonenal
3. lipids
4. liver enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP)
5. malondialdehyde
6. γ-glutamyltransferase
7. cytokines (TNF-α, LT-α, IL-1α, IL-1β, IL-6, TNF-RI, TNF-RII, IFN-γ, IL-12, IL-2, IL-15, IL-8, IL-4, IL-5, IL-17, IL-23, IL-10, IL-13, and IL-18)
8. lymphocytes
9. platelets

Specifically, subjects will participate in a 3-month, two-group, randomized intervention, where one group (n=10) will take 1 gram/day RBAC and the other group (n=10) will take a placebo to compare differences in outcomes between the two groups. The results of the study are intended to address the multi-faceted physiological problems of NAFLD patients by testing the efficacy of a nutritional supplement intervention on multiple outcomes in this population.
