Brief Summary:
Cushings syndrome CS and acromegaly determine myopathy and muscle weakness which persist long-term after control of hormone excess Fatty infiltration in skeletal muscle myosteatosis is associated with muscle atrophy frailty and increased morbidity and mortality in several human models The study is aimed at evaluating muscle structure in patients with controlled CS and acromegaly and correlate it with functional tests of muscle strength In addition circulating molecules potentially mediating persistent myopathy in these patients will also be assessed
Detailed Description:
Prior chronic exposure to glucocorticoids or growth hormone GH determines fat infiltration and persistent impairment of muscle structure in cured patients with CS or acromegaly respectively All this leads to irreversible changes in muscle strength and performance markedly affecting morbidity and quality of life of these patients In particular muscle weakness would contribute significantly to the development of severe arthropathy associated with excess GH as well as deterioration of bone status and increased risk of fracture as described in patients with either CS or acromegaly in remission Our aim is to evaluate whether muscular MRI is a useful tool for the assessment of myopathy and myosteatosis in these patients If this is the case we would have identified a non-invasive test that would allow the follow-up of patients at risk of developing functional motor problems anticipating the onset of muscle weakness or fatigue and consequent deterioration of their quality of life On the other hand we will examine the role of microRNAs which can suppress the process of myogenic differentiation as potential modulators of myopathy in these conditions Indeed microRNAs could be used in clinical practice as markers to identify patients at risk of myopathy and develop strategies for their prevention Clarifying the impact of muscle fat infiltration on muscle strength would allow us to better understand the interaction between muscle and adipose tissue encouraging research on potential mediators of this relationship such as myostatin MSTN able to direct the mesenchymal cell muscle towards the formation of adipocytes at the expense of myocytes and adiponectin ApN which keeps the levels of fat in the muscle low while favoring the formation and regeneration of muscle tissue
