Acromegaly is frequently complicated by fragility vertebral fractures and diabetes mellitus. Since type 2 diabetes mellitus is a cause of secondary osteoporosis in the general population, in this cross-sectional study we aimed at investigating the association between diabetes mellitus and vertebral fractures in males with acromegaly. Fifty-seven patients (median age 47xa0years, range: 24–85) with active (21 cases) and controlled (36 cases) acromegaly and 57 control subjects were evaluated for bone mineral density (BMD) by DXA and vertebral fractures by a quantitative morphometric analysis. Diabetes mellitus was found in 18 patients and 18 control subjects. The prevalence of vertebral fractures was higher in acromegalic patients as compared with the control subjects (50.9 vs. 10.5%; χ2: 21.8; Pxa0<xa00.001). Acromegalic patients with fractures had serum IGF-I values significantly higher (Pxa0=xa00.009), longer duration of active disease (Pxa0<xa00.001) and higher prevalence of active acromegaly (Pxa0=xa00.007) and diabetes mellitus (Pxa0=xa00.04) as compared to patients who did not fracture. When acromegaly was active, the prevalence of vertebral fractures was high independently of the coexistent diabetes mellitus. On the contrary, when acromegaly was controlled the prevalence of vertebral fractures was significantly higher in patients with diabetes as compared to patients without diabetes (62.6 vs. 28.0%; Pxa0=xa00.04). In both diabetic and non diabetic patients, vertebral fractures occurred independently of BMD. In conclusion, this study suggests that diabetes mellitus may be associated with an increased prevalence of vertebral fractures in males with acromegaly. However, this effect seems to be relatively attenuated in the presence of persistent GH hypersecretion.

Hyperprolactinemia may cause bone loss but data on fractures are scanty. The aim of this study was to evaluate the prevalence of vertebral fractures in women with prolactin (PRL)-secreting adenoma. In this cross-sectional study, 78 women (median age 45.5xa0years, range: 20–81) with PRL-secreting pituitary adenoma (66 with microadenoma and 12 with macroadenoma) and 156 control subjects, with normal PRL values and with comparable age to patients with hyperprolactinemia, were evaluated for vertebral fractures by a morphometric approach and for bone mineral density (BMD) by a dual-energy X-ray absorptiometry at lumbar spine. Vertebral fractures were shown in 25 patients with PRL-secreting adenoma (32.6%) and in 20 controls (12.8%, Pxa0<xa00.001). Fractured patients were significantly older (Pxa0<xa00.001) and had lower BMD T-score (Pxa0<xa00.001), longer duration of disease (Pxa0<xa00.001), higher serum PRL (Pxa0=xa00.004) and lower serum IGF-I (Pxa0<xa00.001) values as compared to patients who did not fracture. The prevalence of vertebral fractures was significantly (Pxa0<xa00.001) higher in post-menopausal women with PRL-secreting adenoma as compared to pre-menopausal patients. Fractures occurred more frequently (Pxa0=xa00.01) in patients with untreated hyperprolactinemia versus patients treated with cabergoline. Logistic regression analysis demonstrated that duration of disease maintained a significant correlation with vertebral fractures (odds ratio 1.16, C.I. 95% 1.02–1.33) even after correction for age, menopausal status, treatment with cabergoline, BMD, serum IGF-I and serum PRL values. Hyperprolactinemia is associated with high prevalence of radiological vertebral fractures in women with PRL-secreting adenoma.
