There is preliminary evidence that Omega 3, a compound naturally found in fish oil, reduces the amount of fat stored in the liver and improves liver function. The purpose of this study is to see whether this observation is correct.

Condition Intervention Phase
Non Alcoholic Fatty Liver Disease Drug: Omacor Drug: lactose tablet Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: The Effect Of Omega-3 Fatty Acids on Non-alcoholic Fatty Liver Disease

Further study details as provided by University of Edinburgh:

Primary Outcome Measures:
  • Liver appearance on ultrasound [ Time Frame: 6 months ]
    The primary endpoint is improvement in grading on ultrasound assessment at six months. Liver brightness and posterior attenuation on ultrasound has previously been shown to correlate significantly with fat scores on liver biopsy.

Secondary Outcome Measures:
  • Liver function tests [ Time Frame: 6 months ]
    the effect of omega-3 fatty acids on serum liver function tests will be assessed following 6 months of treatment.

  • hepatocyte mitochondrial function [ Time Frame: 6 months ]
    heptocyte mitochondrial function will be measured by breath testing following 6 months of omega-3 supplementation

  • Health-related Quality of Life [ Time Frame: 6 months ]
    Health related quality of life scores will be compared with baseline following 6 months of omega-3 supplementation
