About this trial
This is a single-center, proof-of-concept pilot study which uses a cross-over design to compare two dietary interventions/treatments: Western Diet (WD) vs Mediterranean (MD) and impact on quality-of-life parameters in AIH. Participants will receive both treatments through two phases and will be divided into two groups.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Established autoimmune hepatitis (AIH) confirmed according to simplified criteria (>6) or historical confirmatory liver biopsy with inflammation consistent with AIH
Therapeutically stable AIH: no changes to immunosuppression (corticosteroids or baseline immunosuppression) within 4 weeks of study enrollment
Previous enrollment in the Indiana University GRACE study
Fatigue domain score (PROMIS-29) more than population mean (PROMIS 29 score): T-score ≥ 55
Disqualifiers
Concurrent diagnosis of celiac disease
Concurrent use of dedicated dietary intervention (patient driven or else)
Established diagnosis of variant syndrome (AIH with Primary biliary cholangitis, AIH with Primary sclerosing cholangitis)
Child Pugh score > 7

Crossover
Treatments tested in this trial
Dietary assignment
Dietary supplementA total of 48 subjects will be randomized by a computer program into one of two groups: MD or WD. Participation in each dietary arm lasts 8 weeks, with a 6 week washout period in between each arm.

Trial outcomes
Primary outcomes
Change in clinical fatigue via Promis 29
Assessment from the patient only through data collection from the Promis-29 instrument. This 29 item instrument that measures various difficulties in health related quality of life in 7 domains. For this measure, a higher scores equals more of the concept being measured.
Secondary outcomes
Change in overall health related quality of life via Promis 29
Assessment from the patient only through data collection from the Promis-29 instrument. This 29 item instrument that measures various difficulties in health related quality of life in 7 domains. For this measure, a higher scores equals more of the concept being measured.
Changes in liver stiffness and fat content via transient elastography
Assessment from the patient only as measured by VCTE (vibration controlled transient elastography) via FibroScan® and with bioelectrical impedance via INBody®measure. A higher score equals more liver steatosis and fibrosis.
Change in alanine transaminase (ALT) value
Assessment from the patient only through lab results taken from a venous blood draw.
Change in IgG value
Assessment from the patient only through lab results taken from a venous blood draw.
