Mechanism of TIPS to Improve Sarcopenia

Sarcopenia is particularly common in patients with chronic liver disease, especially in patients with decompensated cirrhosis, where the prevalence can be more than 50%. Sarcopenia is an important risk factor for a significant increase in mortality in cirrhotic patients, and is closely associated with a high incidence of complications such as hepatic encephalopathy, ascites, and infections . Recent studies have found that TIPS not only significantly improves clinical symptoms caused by portal hypertension, but may also have a positive effect on skeletal muscle mass and function in patients. Although the effect of TIPS in improving sarcopenia has been preliminarily confirmed, its mechanism is not yet fully understood. Therefore, there is an urgent need to explore the mechanism of action of TIPS to improve sarcopenia and provide guidance for clinical treatment options.

According to whether the sarcopenia improved or not in patients after TIPS, patients were divided into sarcopenia group and non-sarcopenia group, and the relationship between FGF21 levels and sarcopenia improvement in patients after TIPS was analyzed by analyzing the differences between the two groups. During the follow-up of patients after TIPS, blood samples were collected to test serum FGF21 levels and imaging examinations were performed to assess the improvement of sarcopenia; changes in nutritional status, muscle strength and function indicators were analyzed in the process of sarcopenia improvement; changes in serological indicators were analyzed in the process of sarcopenia improvement, with a focus on the serum FGF21 level; the combination of the serum FGF21 level and the muscle strength and function indicators, and evaluate their value in the prognosis of TIPS.
