Blood Flow Restriction Training After TIPS Placement in Liver Cirrhosis (MOVE-TIPS)

10 listopada 2026 zaktualizowane przez: German Diabetes Center

Can Blood Flow Restriction Training Counteract Sarcopenia After TIPS in People With Liver Cirrhosis?

The goal of this clinical trial is to investigate whether a 12-week resistance training with mild blood flow restriction following transjugular intrahepatic portosystemic shunt (TIPS) placement, compared with standard care, leads to improvements in muscle mass and muscle function in individuals with liver cirrhosis. The primary focus is on the functional recovery of skeletal muscle following TIPS rather than solely on morphological changes in muscle mass. In addition, people-reported outcomes, clinical trajectories, and metabolic and inflammatory parameters will be assessed to identify potential predictors of functional response to structured physical activity following TIPS.

Szczegółowy opis

People with liver cirrhosis frequently develop complications such as refractory ascites and variceal bleeding, for which transjugular intrahepatic portosystemic shunt (TIPS) placement is an established therapeutic option to decompress portal hypertension and improve symptom burden. However, although TIPS addresses hemodynamic derangements, it does not reliably ameliorate the profound functional impairment and muscle wasting (sarcopenia) that characterize advanced chronic liver disease. Physical exercise and structured activity have emerged as promising non-pharmacological interventions to counteract sarcopenia, improve functional capacity, and enhance health-related quality of life in people with liver disease. Although observational studies suggest that skeletal muscle mass may increase in the months following TIPS placement, these changes are frequently not accompanied by proportional improvements in muscle strength or functional capacity. This dissociation highlights the concept of impaired muscle quality in advanced liver disease and indicates that hemodynamic improvement alone may be insufficient to restore physical function after TIPS. Given the unmet clinical need to address persistent functional decline after TIPS placement and the strong association of sarcopenia with adverse outcomes, there is a compelling rationale to investigate whether a structured, supervised exercise intervention initiated after TIPS placement can improve objective measures of functional capacity, muscle health, and clinical outcomes.

Of note, conventional resistance training (CREST) involves high mechanical loads (~70% of one-repetition maximum [1-RM]) and may not be suitable for all people after TIPS placement, especially for those with advanced sarcopenia. In recent years, blood flow restriction training (BFRT) has emerged as a promising alternative training method in healthy individuals and athletes, resulting in muscular adaptations comparable to CREST, but at substantially lower training intensities (e.g., ~30% 1-RM). Specifically, during BFRT, a cuff is placed proximally on the exercising limb and inflated to an individualized pressure corresponding to up to ~80% arterial inflow restriction with complete venous occlusion.

Therefore, the present study aims to prove whether a 12-week BFRT intervention not only increases muscle mass but even more improves muscle function in people after TIPS placement. This will be done by evaluating both physiological and person-centered endpoints, thereby providing a scientific basis for integrating BFRT targeted physical activity into the standard care pathway for individuals with cirrhosis undergoing TIPS.
