Patients: Nineteen acromegalic patients (8 females, 21-69 years-old, with macroadenoma, microadenoma or no evidence of pituitary tumor in 15, 2, 2, respectively) resistant to first generation somatostatin analogs (FG-SA) at high doses and/or intolerant to pegvisomant were switched to pasireotide LAR (PasLAR). Eleven had persistent disease after neurosurgery and two had also undergone radiosurgery (12 and 24 months before starting PasLAR). Six complained of acromegalic headache...

Parathyroid glands regulate bone metabolism through PTH, while bone modulates parathyroid function through calcium and FGF23. Bone releases the matrix protein osteocalcin (OC), whose hormone function is increasingly evident. We tested the hypothesis that OC may modulate parathyroid function. The 6 hours-stimulation of human parathyroid cells derived from adenomas (PAds) (n = 5) with γ-carboxylated OC (GlaOC; 40–60 ng/ml) increased the expression levels ...
