Trial 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. Read more about this study

About this study

Official title: Influence of Irisin on Muscle Quality in a Cohort of Charcot-Marie-Tooth Patients

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.

Read the detailed description

Currently, there are no effective treatment approaches for CMT other than treating symptoms with medications such as nonsteroidal anti-inflammatory drugs that provide relief of lower back or leg pain. Except for the most severe cases in which orthopedic surgery is recommended to correct pes cavus and/or spine deformities, rehabilitative management of patients with CMT has shown that physical activity can provide a moderate increase in muscle strength and musculoskeletal function, improving activities of daily living. Benefits of exercise on the musculoskeletal system are widely recognized as primary non-pharmacologic intervention for several diseases. The positive outcome of physical activity is achieved not only by the mechanical load applied on the musculoskeletal system, but also via biochemical signals, the myokines, secreted during contraction that act locally or systemically on several body districts. Among these, Irisin is a hormone-peptide synthesized from skeletal muscle performing key actions on the whole-body metabolism. In humans, the investigators have documented with several studies an existing positive association between circulating levels of Irisin and bone mineral density. Very recently, in muscle biopsies of older adult subjects, the investigators also observed that the expression of the Irisin precursor, the fibronectin type III domain-containing protein 5 (FNDC5), was positively associated with Irisin serum levels and osteocalcin mRNA expression in bone biopsies, indicating a strong correlation between healthy muscle and bone tissues. In humans, low levels of circulating Irisin have been found to be predictive of muscle weakness and atrophy, and Irisin has been identified as a sensitive molecular biomarker for sarcopenia in postmenopausal women. In addition, women older than 65 years undergoing a 12-week exercise program showed an increase in circulating Irisin and an improvement in isokinetic leg strength and grip strength compared with control women. Moreover, there was a positive correlation between Irisin levels with grip strength and leg strength in the exercise group, suggesting a causal relationship between improved muscle strength and increased Irisin concentration. Although numerous reports recommend increasing muscle strength in CMT patients to prevent progressive distal weakness and muscle atrophy, few studies have investigated the possible key determinants of muscle quality in these patients. Therefore, the aim of this study was to evaluate circulating Irisin levels in a population of 20 CMT patients as well the association of Irisin with biochemical parameters and muscle quality. In addition, the investigators compared these data with unpublished data previously obtained in healthy subjects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bioimpedenziometry, Handgrip strenght evaluationDiagnostic test

    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.

  • Evaluation on blood specimensDiagnostic test

    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)
