  Purpose

Autoimmune hepatitis is a chronic disease of the liver caused by an alteration of the immune response that attacks the body's own hepatocytes, progressively, leading to cirrhosis and liver failure.

There are few studies on dietary management in hepatitis and most of theme have focused on micronutrients specifically vitamin D to prevent osteoporosis, and decreased symptoms of other diseases associated, but few recommendations have been made regarding a complete dietary approach. Fiber has been proven to increase the excretion of nitrogen products and consequently reduce its blood levels and an adequate protein intake (1.2g/kg) has shown to decrease endogenous catabolism in cirrhotics patients.

The implementation of a high protein high fiber nutrition plan and improves nutritional status of patients with autoimmune cirrhosis.

Primary Outcome Measures:
  • Nutritional Status [ Time Frame: Participants will be assessed for six months ] [ Designated as safety issue: No ]
    Measured with the following parameters:body weight and height (to calculate BMI), triceps skinfold and mid-arm circumference (to calculated mid-arm muscle circumference, fat mass, fat free mass total, intracellular and extracellular body water obtained by bioelectrical impedance analysis and individual vectors obtained by bioelectrical impedance vector analysis.


Secondary Outcome Measures:
  • Minimal hepatic encephalopathy [ Time Frame: Participants will be assessed for six months ] [ Designated as safety issue: No ]
    Assessed by psychometric Hepatic Encephalopathy (PHES) and Critical Flicker Frequency (CFF), at visit 0 months and 6 months visit.

  • Quality of life [ Time Frame: Participants will be assessed for six months ] [ Designated as safety issue: No ]
    Assessed by CLDQ and SF-36 questionnaires, at visit 0 months and 6 months visit.


Estimated Enrollment: 40
Study Start Date: January 2012
Estimated Study Completion Date: July 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Autoimmune hepatitis (Non-cirrhotic)
A personalized high protein high fiber dietary plan will be provided to each participant from both groups. Each participant will receive nutritional counseling once a month during six months.
Dietary Supplement: High protein high fiber diet

A personalized high protein high fiber dietary plan will be provided to each participant from both groups. Each participant will receive nutritional counseling once a month during six months.

Each participant will receive nutritional counseling once month during six months.

Experimental: Autoimmune hepatitis (Cirrhotic)
A personalized high protein high fiber dietary plan will be provided to each participant from both groups. Each participant will receive nutritional counseling once a month during six months.
Dietary Supplement: High protein high fiber diet

A personalized high protein high fiber dietary plan will be provided to each participant from both groups. Each participant will receive nutritional counseling once a month during six months.

Each participant will receive nutritional counseling once month during six months.


Detailed Description:

Each participant will receive a high protein (1.2g/kg/day) and high fiber (30g/day) dietary plan. The monitoring of adherence to the diet will be once a month for the duration of the study period.

There will be an nutritional assessment by anthropometric techniques: arm circumference, triceps skinfold, weight, height and body mass index as parameters of malnutrition by taking the standard for cirrhotic patients. Body composition was measured by bioelectric impedance to obtain fat mass, lean and total fluid content.

The presence of minimal hepatic encephalopathy will be assessed by PHES and CFF and applied three times during the study and the quality of life questionnaire SF-36 CLDQ and will be held in direct interview at the first visit and at study end.

Were also measured serum concentrations of ammonium, TNF-alpha, IL-1, IL-6, IL-10, renin, angiotensin and aldosterone.
