Beskrivelse
Inclusion Criteria:
- Adolescents ages 12-19 years (range as defined by World Health Organization).
- BMI ≥ 35 to 69 kg/m2 (minimum BMI per current guidelines for WLS in adolescents). An upper limit of BMI was set to avoid rare outliers in BMI.
- Meet current standard of care eligibility criteria for adolescent WLS.
- Liver biopsy for clinical indication to evaluate for NASH within 1 year of enrollment. Biopsy must confirm definite or borderline NASH with a minimum histological NASH Activity Score of ≥ 3.
- No evidence of any other liver disease by history, screening tests or histological evaluation.
- Written informed consent from parent/legal guardian and informed assent from the adolescent
Exclusion Criteria:
- Evidence of other chronic liver disease: autoimmune hepatitis; hepatitis B; hepatitis C; hemochromatosis; alpha-1-antitrypsin (A1AT) deficiency; Wilson disease; use of medications known to cause fatty liver for > 2 consecutive weeks in past year (i.e. systemic glucocorticoids, tetracycline, anabolic steroids, valproic acid); alcohol intake >10 gm/day females & >20 gm/day males.
- Non-compensated liver disease with any of the following: hemoglobin <10 g/dL; white blood cell count <3,500 cells/mm3, platelet count <130,000 cells/mm3 of blood, direct bilirubin >1.0 mg/dL, total bilirubin >3 mg/dL, albumin <3.2 g/dL, international normalized ratio (INR) >1.4
- Active psychiatric disorder that would prevent eligibility for WLS or impede adherence to CLI, including clinically significant depression (hospitalization or suicidal ideation) in past 12 months.
- Any medical condition preventing eligibility for WLS including but not limited to micronutrient deficiencies (e.g. iron) refractory to medical therapy or inflammatory bowel disease.
- Poorly controlled Type 2 diabetes mellitus (T2DM) defined as hemoglobin A1C (HgbA1c) > 10%.
- Initiation of high dose vitamin E (>400 IU per day) or other medications which could alter NASH histology at any time after baseline liver biopsy or during the trial. Stable dose of vitamin E that was started 12 months or more prior to biopsy is allowed.
- Weight reduction of >5% between baseline liver biopsy and enrollment, as weight loss >5% may change NASH severity.
- Inability or failure to provide informed assent/consent
- Current enrollment in another clinical trial or receipt of an investigational study drug within 6 months prior to the baseline liver biopsy
- Any female who is currently nursing, planning a pregnancy, known or suspected to be pregnant, or has a positive pregnancy screen
- Inability to travel to study site at intervals necessary for clinical interventions (CLI or WLS).
- Prior history of WLS.

Ingen inngripen: Weight Loss Surgery
Adolescents who will have Weight Loss Surgery and had biopsy-confirmed NASH.
The Weight Loss Surgery is not part of the study.
The investigators are following the adolescents after the surgery.

|
Eksperimentell: Comprehensive Lifestyle Intervention
Comprehensive Lifestyle Intervention - Dietary, activity and behavioral interventions.
Adolescents who have biopsy-confirmed NASH and wish to participate in a Comprehensive Lifestyle Intervention (26+ contact hours) including individual meetings with a study dietitian, group nutrition classes, behavior management modules and physical activity goals.
|
Dietary, behavioral and activity interventions designed to reduce weight.
