Hepatic Energy Fluxes in NASH and NAS Patients
United States30 participantsStarted 2019-07-01
Plain-language summary
Diseases along the nonalcoholic fatty liver disease spectrum, which are tightly coupled to the obesity epidemic, are soon to become the commonest indication for liver transplantation in the United States. Bariatric surgery shows great promise in the treatment of these diseases. The studies proposed herein will be the first to measure in humans the relationships among (i) the liver's ability to burn fat and make glucose, two of its primary functions; (ii) the severity of nonalcoholic fatty liver disease; and (iii) the responses to bariatric surgery. These experiments will support deeper future mechanistic investigations of the metabolic mechanisms underlying nonalcoholic steatohepatitis (NASH) improvement with bariatric surgery.
The premise of this study is that deranged hepatic mitochondrial metabolism is a key biomarker and mediator of the nonalcoholic fatty liver disease (NAFLD)/NASH continuum, and the central hypothesis the investigators will test is that preoperative hepatic fat oxidation and glucose production flux parameters differ between low versus high NAFLD activity score (NAS), and response of the liver to bariatric surgery can be predicted by preoperative fluxes.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age 18 to 67 years at eligible visit
* Diagnosed with NASH with a total NAS ≥ 3 including a ballooning score of at least 1, or non-NASH/NAFLD with a total NAS ≤3, or Diagnosed with T2DM or prediabetes, HbA1c\< 8% , or CAP score greater than or equal to 248 on Fibroscan
* Body Mass Index (BMI) 30.0-55.0 kg/m2 at eligibility visit
* Willingness to accept surgical intervention after an individual seminar session
* All patients must have insurance with no exclusion for obesity related treatments or management of obesity surgery complications. This applies to all patients enrolled in the study
* Expect to live or work within approximately three-hour traveling time from the study clinic for the duration of the one-year trial
* Willingness to comply with the follow-up protocol and successful completion of the run-in
* Written informed consent
* Suitable for liver biopsy using the percutaneous approach
* Vulnerable populations will not be targeted for inclusion, but those noted in section 9.1 may be allowed to participate provided they met all of the inclusion and none of the exclusion criteria.
Exclusion Criteria:
* Cardiovascular event (myocardial infarction, acute coronary syndrome, coronary artery angioplasty or bypass, stroke) in the past six months.
* Current evidence of congestive heart failure, angina pectoris, or symptomatic peripheral vascular disease.
* Cardiac stress test indicating that surgery or IMM would not be safe.
* Pulmonary embolus or thr…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
