Muscle in Acromegaly and Cushing's Syndrome

Cushing's 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.
