French-German Cohort Study to Determine Factors Associated With Weight Loss in Amyotrophic Lateral Sclerosis (FG-CoALS)

November 21, 2024 updated by: University Hospital, Limoges

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. Studies have shown the importance of weight loss at the time of diagnosis and during the progression of the disease. However, the pathophysiological mechanisms behind weight loss remain unknown. Identifying these mechanisms could make it possible to propose an effective therapeutic strategy against weight loss for ALS patients, which could improve their survival and quality of life. In this context, the investigators are proposing an innovative multidisciplinary project aimed at structuring a large Franco-German cohort to identify the markers associated with weight loss in ALS.

Participants will undergo high quality standard care for ALS patients. In addition, participants will be asked to respond different questionnaires and blood samples will be taken for analysis to identify biological markers.

Detailed Description

ALS is the most frequent adult onset motor neuron disease and is highly variable in terms of clinical features, genetics, and neuropathology. A large body of evidence has demonstrated the importance of weight loss at the time of diagnosis and during disease progression. Weight loss affects between one and two-thirds of patients and is adversely associated with survival. High caloric nutrition was able to slow weight loss and prolong survival in fast progressing ALS patients. Pathophysiological mechanisms underlying weight loss remain unknown because high-quality cohort data collecting clinical features, genetics, omics, and imaging related to the metabolic and disease status of patients are lacking. The investigators hypothesize that weight loss in ALS patients is biologically driven through specific pathways. The investigators propose an innovative and ambitious multidisciplinary project to structure a large French-German cohort to identify markers associated with weight loss. The investigators aim at identifying the biological correlates of weight loss to disentangle the mechanistic basis of this critical symptom and to determine clinical and biological profiles along with their impact on disease progression and survival.
