History of Changes


The purpose of this study is to evaluate the effect of a one-year nutritional intervention with either betaine or vitamin E supplementation, or a weight reducing diet and exercise program on liver steatosis and steatohepatitis.

Drug : antioxidant vitamin E
Behavioral : weight reduction and exercise
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures

  • The change in grading of inflammation assessed by liver biopsy from month 0 to month 12 of the study [ Time Frame: month 0 and month 12 ]
Secondary Outcome Measures:
  • Liver histology for steatosis and fibrosis staging [ Time Frame: month 0 and month 12 ]
  • Liver immuno-histochemistry for adducts of MDA: a product of LP [ Time Frame: month 0 and month 12 ]
  • Alpha-smooth muscle actin (alpha-SMA): a marker of hepatic stellate cell activation [ Time Frame: month 0 and month 12 ]
  • Transforming growth factor (TGF-beta): a pro-fibrogenic cytokine involved in fibrogenesis [ Time Frame: month 0 and month 12 ]
  • Liver lipid peroxides and TNP-alpha [ Time Frame: month 0, month 6 and month 12 ]
    For oxidative stress and inflammation in the liver
  • Liver steatosis and volume will be assessed by ultrasound [ Time Frame: month 0 and month 12 ]
  • Liver enzymes and IR (HOMA and QUICKY) will also be measured [ Time Frame: month 0, month 6 and month 12 ]
  • Lipid peroxides, TNF-alpha, vitamin E and C in plasma [ Time Frame: month 0, month 6 and month 12 ]
    Parameters for oxidative stress and antioxidant capacity

Enrollment: 30
Study Start Date: October 2003
Study Completion Date: December 2010
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)

Arms Assigned Interventions
Experimental: Vitamin E
alpha-tocoperol, capsules, 2 per day
Drug: antioxidant vitamin E

Vitamin E 800IU per day for 12 months

Behavioral: weight reduction and exercise

Patients will be asked to consume a self-selected, low fat, low-calorie diet of approximately 1200 kcal/d, which is consistent with American Heart Association guidelines for healthy weight reduction. Subjects will be provided with a videotape involving a structured 20 min aerobic exercise to be performed 3x/week.

Other Name:
  • This arm was removed from the study protocol, as the enrollment was slow and
  • a high drop-out rate was observed in the weigh-loss arm



Ages Eligible for Study: 18 Years and older  
Sexes Eligible for Study: All  
Accepts Healthy Volunteers: No  


Inclusion Criteria:

  • Baseline liver biopsy with macrovesicular fatty degeneration with inflammation (lobular or portal), with or without Mallory bodies, hepatocyte damage, and/or fibrosis diagnostic of NAFLD
  • Convincing evidence of negligible alcohol consumption (< 20 grams of ethanol per day) obtained from a detailed history, confirmed by at least one close relative
  • If hyperlipidemia or diabetes, stable drug regimen required for the 6 months prior to and during the study
  • Willingness to maintain stable weight and normal exercise program for the duration of the study, if randomized to vitamin E or betaine

Exclusion Criteria:
  • Liver disease of other etiology diagnosed as per routine medical investigation (e.g., chronic viral hepatitis, auto-immune chronic hepatitis, primary biliary cirrhosis or genetic liver disease such as Wilson's disease, hemochromatosis, alpha-1 antitrypsin deficiency, or biliary obstruction)
  • Complications of liver disease such as recurrent variceal bleeding, resistant ascites, spontaneous portosystemic encephalopathy, or bacterial peritonitis
  • Concurrent medical illness contra-indicating a liver biopsy, history of unexplained bleeding, hemophilia or abnormal coagulation results as per routine laboratory work-up or other reason judged by the hepatologist to contra-indicate a percutaneous liver biopsy
  • Medications known to precipitate steatohepatitis (corticosteroids, high dose estrogens, methotrexate, amiodarone, calcium channel blockers, spironolactone, sulfasalazine, naproxen, oxacillin or ampinovire) in the 6 months prior to entry
  • Antioxidant vitamin supplementation, ursodeoxycholic acid, or any other experimental drug 6 months prior to study entry
  • Pregnant or lactating
