The European Working Group on Sarcopenia in Older People (EWGSOP2) defined in 2018 ‘sarcopenia as muscle disease (muscle failure), with low muscle strength overtaking the role of low muscle mass as a principal determinant’; sarcopenia increases risk of falls and fractures, impairs ability to perform activities of daily living, leads to mobility disorders and low quality of life and death. The diagnosis is confirmed by low muscle quantity or quality. The muscle quanti...

Introduction: Obesity is a pathological condition characterized by a low-grade systemic inflammatory state that predisposes to the onset of some diseases, such as hypertension, diabetes, and hyperlipidemia. Also, obesity can impact bone metabolism, but its effects are controversial.Aims: This observational study aimed to evaluate and correlate the bone mass with the lipidic profile, adipocytokines, glucose metabolism, hepatic function and purine metaboli...

Aims: To study the association of protein tyrosine phosphatase (LMW–PTP/ACP1) polymorphism with bone mineral density and metabolic parameters of bone remodelling.Methods: BMD (g/cm2) was measured by DEXA in 760 subjects: 448 normal BMD (359F/89M; 49.7±12.9 years; 30.2±5.4 kg/m2) and 312 osteoporosis (265F/47M; 63.9±10.4 years; 27.16±4.4 kg/m2). Metabolic bone remodelling parameters were analyzed: ...

Introduction: Cushing’s disease (CD) is responsible for 80% of endogenous Cushing’s syndrome (CS). However, distinguishing the cause of ACTH-dependent CS – CD vs ectopic CS – can be extremely difficult. Bilateral inferior petrosal sinus sampling (IPSS) has the highest diagnostic accuracy in this evaluation.Objectives: The aims of this study were to determine the accuracy of bilateral IPSS in the differential diagnosis of ACTH-dependen...

Trabecular bone score (TBS) is a recent noninvasive analytical method, based upon DXA images, related to bone microarchitecture or bone quality; together, TBS and DXA may evidence bone strength. Falls and osteoporotic fractures increase with ageing, while both BMD and vitamin D levels slowly decline. Data about the influence of vitamin D on the TBS are scarce.Aim: To evaluate the influence of the blood vitamin D levels on the TBS in normal men.<p cla...

Increased recognition of the morbidity and mortality due to osteoporosis in men are main issues of public health. Ageing and the propensity to falls are the main risk factors for osteoporotic fractures in men; moreover, hypogonadism is an important secondary cause of low bone mineral density (BMD), but very little is known about the effect of hypogonadism treatment on the BMD.Objective: The aim was to study the impact on BMD of the treatment of male hypo...

Osteoporosis and diabetes mellitus type 2 (DM2) have severe health consequences, with high morbidity and mortality risks.Aims: To study the differences of the sex steroid hormones levels and the free androgen index (FAI) in DM2 men with low BMD and osteoporosis and their relationships with BMD.Materials and methods: In 317 men with DM2, the BMD (g/cm2) was evaluated at the lumbar spine (L1-L4), at t...
