Butyrate or Intensive Lifestyle Modification in Type 1 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease
Butyrate or Intensive Lifestyle Modification in Type 1 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease: A Factorial Randomized Clinical Trial
Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is highly prevalent in individuals with type 1 diabetes (T1D) and is associated with increased cardiovascular and metabolic risk. However, evidence regarding effective therapeutic strategies for MASLD in T1D remains scarce. Lifestyle modification has shown benefits in obesity and type 2 diabetes, whereas butyrate, a microbiota-derived short-chain fatty acid, has emerged as a potential therapeutic approach because of its anti-inflammatory and metabolic effects. This study aims to evaluate the efficacy of intensive lifestyle modification, butyrate supplementation, or their combination on hepatic steatosis in individuals with T1D and MASLD.
Methods: BEAM-T1D is a factorial, randomized, 6-month, parallel-group, placebo-controlled clinical trial conducted at the Regional University Hospital of Malaga. A total of 200 adults with T1D and MASLD will be randomized (1:1:1:1) to receive: (1) standard lifestyle recommendations plus placebo; (2) intensive lifestyle modification plus placebo; (3) standard lifestyle recommendations plus butyrate; or (4) intensive lifestyle modification plus butyrate. Intensive lifestyle modification includes a hypocaloric Mediterranean diet and promotion of physical activity. Participants randomized to butyrate will receive 2.25 g/day of microencapsulated sodium butyrate. The primary endpoint will be the change in controlled attenuation parameter (CAP) measured by transient elastography (FibroScan®). Secondary outcomes include changes in liver fat content, insulin resistance, metabolic control, body composition, inflammatory markers, gut microbiota composition, and short-chain fatty acid concentrations.
Results: Participant recruitment is expected to begin in October 2025. The study will evaluate the independent and combined effects of butyrate supplementation and intensive lifestyle modification on hepatic steatosis and metabolic outcomes in individuals with T1D and MASLD.
Conclusion: The BEAM-T1D study will provide novel evidence regarding the potential role of butyrate and intensive lifestyle modification in the management of MASLD in T1D. If effective, these interventions could represent feasible and scalable therapeutic strategies for a population with limited evidence-based treatment options.

介入なし:Placebo + Standard lifestyle recommendations
Participants in this group will not undergo any intervention beyond what is routinely performed in clinical practice.
This group will receive microencapsulated placebo.
|
|
|
プラセボコンパレーター:Placebo + Intensive lifestyle modification
|
Participants will be advised to follow a Mediterranean diet, characterized by the use of olive oil as the main source of fat, regular consumption of vegetables, fruits, legumes, and fish, reduced consumption of red meat and processed meats, and elimination of sugar-sweetened beverages, industrial pastries, and confectionery.
The Mediterranean diet will include a 30% energy restriction based on estimated energy needs (Harris-Benedict equation).
Participants will also be advised to perform ≥150 minutes of moderate-to-vigorous physical activity per week, distributed over at least 3 days, with no more than 2 consecutive days without activity, and to perform 2-3 resistance training sessions per week on non-consecutive days.
This group will receive microencapsulated placebo.
|
|
実験的:Butyrate
|
Participants randomized to this group will receive microencapsulated sodium butyrate (MSB).
Each sachet contains 750 mg sodium butyrate and 1750 mg triglyceride matrix (total 2,500 mg).
Participants will take 3 sachets daily (total daily dose: 2.25 g butyrate): one in the morning, one at midday, and one in the evening.
|
|
実験的:Intensive lifestyle modification + butyrate
|
Participants will undergo both intensive lifestyle modification and receive butyrate as described above. This study will be placebo-controlled: participants not randomized to butyrate will receive placebo sachets identical in size, color, appearance, and taste to the investigational product but without butyrate. Placebo will also be taken three times daily following the same schedule. |

Change from baseline in Mediterranean Diet Adherence at 3 and 6 months
時間枠:Baseline, 3 months and 6 months
|
The 17-item Mediterranean Diet Adherence Questionnaire assesses dietary habits through 17 questions regarding the consumption of traditional Mediterranean diet components (e.g., olive oil, vegetables, fruits, fish).
Each item is scored as 0 (does not meet the criterion) or 1 (meets the criterion), with a total score ranging from 0 (minimum score) to 17 (maximum score).
Higher scores indicate greater adherence to the Mediterranean diet.

Change from baseline in Physical Activity Level at 3 and 6 months
時間枠:Baseline, 3 months and 6 months
|
The Short version of the International Physical Activity Questionnaire (IPAQ) assesses physical activity across three intensities (vigorous, moderate, and walking) over the last 7 days. Total physical activity is calculated as a continuous variable expressed in Metabolic Equivalent of Task minutes per week (MET-minutes/week), summing the duration (minutes/week) of each activity type multiplied by its specific MET value (walking = 3.3, moderate = 4.0, vigorous = 8.0). Higher MET-minutes/week indicate higher levels of physical activity. Sedentary behavior is assessed by measuing the total time spent sitting during a typical weekday over the last 7 days (including time at work, home, study, or leisure). The score is expressed as total minutes or hours of sitting time per day. Higher values indicate greater sedentary behavior. |

Change from baseline in Long-term Physical Activity Patterns at 3 and 6 months
時間枠:Baseline, 3 months and 6 months
|
The validated version of the Nurses' Health Study and Health Professionals' Follow-up Study physical activity questionnaire assesses the average time per week spent on specific recreational activities (e.g., walking, jogging, cycling, swimming, running) over a longer recall period.
Each activity is assigned a standard MET value based on intensity (the number of METs corresponding to each activity were calculated using the Compendium of Physical Activities).
Total activity is computed as the sum of MET-hours per week (MET-hours/week) by multiplying the weekly hours dedicated to each activity by its corresponding MET value.
Higher scores reflect greater energy expenditure from physical activity.
