Male osteoporosis has been neglected for too long time and there is need for a change. This condition is clearly under-estimated, under-diagnosed and under-treated. The diagnosis is often made late in the natural history of the pathology or even after a fracture event. Guidelines on screening politics do not agree whether and when men should be considered, and clinical trials are far less performed in men with respect to women. Actually, most of our knowledge on male osteoporosis, especially regarding treatment, is extrapolate from the female counterpart. Male osteoporosis is frequently secondary to other conditions and often associated with comorbidities. Therefore, identification of specific causes of male osteoporosis is essential to drive a correct and personalized treatment. Moreover, men have more osteoporosis-related complications and higher mortality rate associated with fractures. Furthermore, not only fewer men receive a correct and timely diagnosis, but also fewer men receive adequate treatment, and adherence to therapy is far less in men than in women. Of note, very few studies assessed the effect of antiosteoporotic treatments in men and most of them considered only bone density as primary endpoint. This review focuses on the areas that are still nebulous in male osteoporosis field, from identification of subjects who need to be evaluated for osteoporosis and screening programs dealing with primary prevention to diagnostic procedures for good estimates of bone quantity and quality and precise calculation of fracture risk and personalized treatment that take into account the pathophysiology of osteoporosis.

In this study, the effect of high-dose octreotide LAR on glucose metabolism in patients with acromegaly was investigated.


A post-hoc analysis of a clinical trial enrolling 26 patients with acromegaly not controlled by standard maximal somatostatin analog (SSAs) dose and randomized to receive high-dose (60 mg/28 days) or high-frequency (30 mg/21 days) octreotide i.m. injection (octreotide LAR) for 6 months.


Glucose metabolic status was defined as worsened when a progression from normoglycemia to impaired fasting glucose (IFG) or from IFG to diabetes occurred or when an increase of HbAlc by at least 0.5% was demonstrated. An improvement of glucose metabolism was defined in the presence of a regression from IFG to normoglycemia and/or when HbAlc decreased by at least 0.5%.


Glucose metabolic status remained unchanged in a majority of patients (16/26 patients, 65.3%), worsened in six patients, and improved in four patients. Pre-existing metabolic status did not predict worsening of glucose metabolism, which, conversely, was significantly related to persistent biochemical activity of the disease. In fact, patients with worsened glucose metabolism exhibited a less frequent decrease in serum GH and IGF1 levels, compared with patients with improved or unchanged glucose metabolism (2/6 vs 18/20; P=0.01).


An increase in octreotide LAR dose or frequency did not impact on glucose metabolism in most patients. Worsening of glucose metabolic status occurred in close relation with persistently uncontrolled acromegaly.
