Exercise Training Decreases Alcohol Consumption and Tissue Injury by an FGF21-dependent Mechanism
연구 개요
상세 설명
Alcohol use disorder is a major driver of continued liver injury in alcohol-related liver disease. Patients with ALD also commonly develop sarcopenia, impaired skeletal muscle function, fatigue, mitochondrial dysfunction, reduced exercise capacity, and physical frailty. Exercise may improve muscle and metabolic function and may also reduce alcohol craving and consumption. FGF21 has been proposed as a mechanistic link among exercise, skeletal muscle, liver injury, metabolism, and alcohol-related behavior.
This is a randomized, controlled, unblinded study of 30 adults with AUD/ALD. Participants will be randomized 1:1 to endurance exercise plus standard of care (EE+SOC) or standard of care alone (SOC). Participants assigned to EE+SOC will complete a 12-week home-based supervised cycling program three days per week, with a target of approximately 60 minutes per session and intensity adjusted for safety, tolerance, and beta-blocker use. Exercise sessions will be remotely monitored, and fitness testing will occur at Cleveland Clinic. Participants in the SOC arm will continue usual clinical care and their usual physical activity without the structured exercise intervention.
The study will assess alcohol consumption and craving; circulating and skeletal muscle FGF21; liver injury measures; exercise capacity and physical performance; body composition; fatigue; skeletal muscle metabolism and mitochondrial function; and exploratory transcriptomic, proteomic, metabolomic, microbiome, amino acid, protein synthesis, TCA intermediate, and cell-signaling responses.

- MELD score less than 21.
- Able to safely participate in exercise testing and endurance exercise.
- Able to provide informed consent.
- No concurrent renal, cardiac, pulmonary, cerebrovascular, or malignant illness that affects skeletal muscle mass; no diabetes mellitus; and no use of medications that affect skeletal muscle mass/protein turnover as described in the protocol, including anabolic steroids, high-dose corticosteroids, or anticoagulants.
Exclusion Criteria:

실험적: Endurance Exercise
Participants will receive standard of care and complete a 12-week supervised home-based endurance exercise program using a recumbent exercise bike.
|
Stationary/recumbent cycling three days per week for approximately 60 minutes per session for 12 weeks.
Exercise intensity is targeted at approximately 60-70% heart rate reserve and adjusted for safety, tolerance, and beta-blocker use.
Sessions are remotely monitored by the study team.
Participants who cannot exercise continuously may use rest breaks and complete the prescribed exercise within the limits described in the protocol.

간섭 없음: Standard of Care
Participants will continue usual clinical care and their current pattern of physical activity and will not participate in the structured endurance exercise intervention
