Butyrate or Intensive Lifestyle Modification in Type 1 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease

Starting soon · Not applicable · Has a placebo group

Conditions studied: Type 1 Diabetes

In brief

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.
