Outcomes

Primary Outcome Measures

Change from baseline in liver function test
Liver function tests as defined by serum ALT, AST and ALP
Change from baseline in metabolic markers
Metabolic markers as defined by lipid profile
Change from baseline in immunological markers
Immunological markers as defined by TNF-α, LT-α, IL-1α, IL-1β, IL-6, TNF RI, IFN-γ, IL-12, IL-2, IL-15, IL-8, TNF RII, IL-4, IL-5, IL-17, IL-23, IL-10, IL-13, and IL-18.

Secondary Outcome Measures

Change from baseline in systolic blood pressure
Systolic blood pressure will be measured to the nearest even digit by use of the Microlife Deluxe upper arm blood pressure monitor. Three readings will be made with the subjects seated after they have rested for five minutes. The average of the three readings will be used in the analysis.
Change from baseline in Diastolic blood pressure
Diastolic blood pressure will be measured to the nearest even digit by use of the Microlife Deluxe upper arm blood pressure monitor. Three readings will be made with the subjects seated after they have rested for five minutes. The average of the three readings will be used in the analysis.
Pulse
Pulse will be measured to the nearest even digit by use of the Microlife Deluxe upper arm blood pressure monitor. Three readings will be made with the subjects seated after they have rested for five minutes. The average of the three readings will be used in the analysis.
Change from Baseline in Quality of Life
The SF-36v2™ Health Survey (15) provides psychometrically-based physical and mental health summary measures and a preference-based health utility index. It is a generic measure that does not target a specific age, disease, or treatment group.

5. Study Description

Brief Summary
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
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: albumin 4-hydroxynonenal lipids liver enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) malondialdehyde γ-glutamyltransferase 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) lymphocytes 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.
