Clinical Trial Summary

Cirrhosis is the 11th leading cause of death in the world. The progression to cirrhosis occurs as a result of chronic hepatic injury, related to excessive alcohol consumption, non-alcoholic steatohepatitis, chronic viral infection. Cirrhosis is accompanied by symptoms that profoundly affect the quality of life of patients. Sarcopenia, or decrease in muscle capacity through loss of muscle mass, is associated with liver disease. Patients with liver disease and sarcopenia have increased morbidity, and higher pre- and post-liver transplant mortality than patients without sarcopenia. The mechanism responsible for the development of sarcopenia in liver disease remains largely misunderstood, as do the mechanisms by which sarcopenia appears to promote complications of liver disease. This study, carried out on a prospective cohort of patients with liver disease, aims at understanding the pathophysiological mechanisms involved in sarcopenia and its consequences.


Description:

Cirrhosis is the 11th leading cause of death in the world. The progression to cirrhosis occurs as a result of chronic hepatic injury, related to excessive alcohol consumption, non-alcoholic steatohepatitis, and chronic viral infection. Cirrhosis is accompanied by symptoms that profoundly affect the quality of life of patients. Sarcopenia, or decrease in muscle capacity through loss of muscle mass, is associated with liver disease. Patients with liver disease and sarcopenia have increased morbidity, and higher pre- and post-liver transplant mortality than patients without sarcopenia. The mechanism responsible for the development of sarcopenia in liver disease remains largely misunderstood, as do the mechanisms by which sarcopenia appears to promote complications of liver disease. This study, carried out on a prospective cohort of patients with stable liver disease, aims at understanding the pathophysiological mechanisms involved in sarcopenia and its consequences. After checking the inclusion criteria, all eligible patients treated at Beaujon Hospital (Clichy) will be invited to participate in the study. After inclusion, clinical and laboratory features (hepatic assessment) will be collected and the blood samples will be taken. During the surgery, a muscle biopsy will be performed on the incision area. No follow-up is planned.

Primary describe the muscle changes that occur during liver disease. Assessment of the histology of the muscle removed during abdominal surgery, by evaluating the vascularity with measurements of CD31 count and aSMA count 1 month after the of inclusion
Primary describe the muscle changes that occur during liver disease. Assessment of the histology of the muscle removed during abdominal surgery by evaluating the muscle stem cells with measurements of Pax7, MyoD and Myogenin 1 month after the of inclusion
Primary describe the muscle changes that occur during liver disease. Assessment of the histology of the muscle removed during abdominal surgery by evaluating gene expression with transcriptomics 1 month after the of inclusion
Secondary Identify circulating mediators that could be responsible for sarcopenia: released by the liver and acting on the muscle. Circulating concentration of mediators / cells suspected of being responsible for sarcopenia:
extracellular vesicles released by the liver
lymphocyte phenotype potentially modified by sinusoidal endothelial cells of the liver
protein array

Secondary Identify circulating mediators that could be responsible for complications of liver disease: released by the muscle and acting on the different organs Circulating concentration of mediators / cells suspected of being released by muscle and contributing to organ dysfunction in liver disease:
extracellular vesicles
myokines
