Clinical Trial Summary

Sarcopenia in chronic kidney disease (CKD) affects 50% of dialysis patients and 20% of patients with non-dialyzed CKD and reduce quality of life and survival. The pathophysiology of uremic sarcopenia is multifactorial (accumulation of toxins, metabolic disturbances, etc.) and poorly characterized. These pejorative factors are associated with malnutrition and a sedentary lifestyle. Currently, there are no strategies to combat sarcopenia with the exception of physical activity, which is only possible for a limited number of patients due to their comorbidities. Developing new pharmacological strategies to combat sarcopenia is necessary. FGF19 is a growth factor produced in the ileum involved in metabolic homeostasis. In the laboratory, a new function of FGF19 has been discovered. FGF19 acts as a hormonal factor stimulating muscle mass and strength. Preliminary studies had shown a decrease in the concentration and secretion of FGF19 in response to a meal in haemodialysis patients. However, the link between FGF19, muscle mass and CKD has never been demonstrated. The aim of this study is to assess the relationship between the concentration and secretion of FGF19 and muscle function in a large population of patients with CKD of different stages. Given the hormonal communication between the bone and the muscle, the investigators will also recover the bone histological parameters from a bone biopsy if dialysis patients are to benefit from this as part of their follow-up. The investigators hypothesize that a decrease in FGF19 concentration and secretion in CKD is associated with a decrease in muscle mass and strength.
