Influence of Irisin on Muscle Quality in a Cohort of Charcot-Marie-Tooth Patients
In Brief
An observational study evaluating Bioimpedenziometry, Handgrip strenght evaluation and Evaluation on blood specimens for Charcot-Marie-Tooth Disease. Completed, enrolled 20 participants across 1 site.
Detailed Summary
Irisin is an exercise-mimetic myokine secreted by skeletal muscle. Compelling evidence in animal models and humans showed that Irisin prevents onset of musculoskeletal atrophy and its low serum levels are predictive of sarcopenia. The investigators evaluated the levels of irisin in patients affected by an hereditary motor and sensory neuropathy, namely Charcot-Marie-Tooth disease (CMT), in order to investigate possible key determinants of their muscle quality and possibly prevent the progressive distal weakness and muscle atrophy.

Timeline
Interventions
The measurement of body composition was performed using Bioimpedance (BIA 101, Akern srl, Pontassieve (FI), Italy). The handgrip dynamometer (Jamar, Sammons Preston, Bolingbrook, IL, USA) was used to determine the isometric force of the forearm.
Serum samples were assayed for calcium, phosphorus, magnesium, iron, lactate dehydrogenase (Ldh), creatine phosphokinase (Cpk), creatine kinase myocardial band (Ckmmb), myoglobin, thyroid stimulating hormone (TSH), 25(OH)-Vitamin D, osteocalcin, bone alkaline phosphatase (b-ALP), C-terminal telopeptide of type I collagen (CTX-I), haptoglobin, sclerostin, myostatin, and Irisin. Irisin serum concentrations were detected using a competitive ELISA kit (AdipoGen, Liestal, Switzerland)
