“…In addition to SDI, TBS has been proposed as another non-invasive technique able to give information on bone microarchitecture. Patients with CS exhibited low TBS values which inversely correlated with the degree of hypercortisolism and which improved more markedly and quickly than BMD after CS remission (94).…”

DIAGNOSIS OF ENDOCRINE DISEASE: Evaluation of bone fragility in endocrine disorders

An underlying disease affecting bone health is present in up to 40 and 60% of osteoporotic postmenopausal women and men respectively. Among the disorders leading to a secondary form of osteoporosis, the endocrine diseases are highly represented. A frequent finding in patients affected with an endocrine-related forms of bone disease is that the skeletal fragility is partially independent of the bone density, since the fracture risk in these patients is related more to a reduction of bone quality than to a decrease of bone mass. As a consequence, bone mineral density evaluation by dual-X-ray absorptiometry may be inadequate for establishing the risk of fracture in the setting of the endocrine-related forms of osteoporosis. In the recent years, several attempts to non-invasively estimating bone quality have been done. Nowadays, some new tools are available in the clinical practice for optimising the fracture risk estimation in patients with endocrine disorders. The aim of this review is to summarise the evidence regarding the role of the different imaging tools for evaluating bone density and bone quality in the most frequent forms of endocrine-related osteoporosis, such as obesity, diabetes, acromegaly, thyrotoxicosis, primary hyperparathyroidism, hypercortisolism and hypogonadism. For each of these disorders, data regarding both the current available tools and the future possible new techniques for assessing bone fragility in patients with endocrine diseases are reported.

“…Osteoporosis, bone fragility and fractures are well-known complications of Cushing's syndrome (124,125,126,127,128). Data obtained from studies with exogenous corticoids have shown that the prevalence of fractures is correlated with their dosage.…”

Ectopic ACTH syndrome (EAS) is rare but is frequently a severe condition because of the intensity of the hypercortisolism that may be dissociated from the tumoral condition. EAS should often be considered as an endocrine emergency requiring an emergency response both in terms of diagnostic procedures and therapeutic interventions. Patient management is complex and necessitates dual skills, in the diagnosis and treatment of CS and in the specific management of neuroendocrine tumors (NET). Therefore, initial management should be performed ideally by experienced endocrinology teams in collaboration with specialized hormonal laboratory, modern imaging platforms and intensive care units. Diagnostic procedures vary according to the endocrine and tumoral contexts but should be reduced to a minimum in intense hypercortisolism. Preventive and curative treatments of cortisol-induced comorbidities, non-specific management of hypercortisolism and etiological treatments should be considered simultaneously. Therapeutic strategies vary according to (1.) the intensity of hypercortisolism, the general condition of the patient and associated comorbidities and (2.) the tumoral status, ranging from resectable ACTH secreting tumors to non-resectable metastatic endocrine tumors or occult tumors. The ideal treatment is complete excision of the ACTH-secreting tumor that can be performed rapidly or after preoperative preparation using cortisol-lowering drugs. When this is not possible, the therapeutic strategy should be discussed by a multidisciplinary experienced team in a personalized perspective and include variable combinations of pharmacological agents, bilateral adrenalectomy and non-specific tumoral interventions. Here we discuss the diagnosis and therapeutic strategies including the modern, currently available tools and emphasize on the operational effectiveness of care.
