Phase II study of the impact of AZD4017, a selective 11β-HSD1 inhibitor, on osteocalcin in post-menopausal osteopenia

Abbas Afroze , Eastell Richard , K Crowley Rachel , Ainsworth Gemma , Brown Sarah , Flanagan Louise M , Fairclough Rebecca J , Stewart Paul M

The causative link between circulating glucocorticoid excess and osteoporosis is established. Although circulating cortisol levels do not change significantly with age, local tissue metabolism may be implicated in age-related bone loss. The enzyme11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) increases local cortisol production, is expressed in human osteoblasts and its activity increases with age leading to a decrease in bone formation. We hypothesised that sele...

Osteocalcin may participate to the bone-parathyroid crosstalk through activation of the calcium-sensing receptor in human parathyroid adenomas

Verdelli Chiara , Stefania Tavanti Giulia , Maggiore Riccardo , Mari Gilberto , Sansoni Veronica , Perego Silvia , Vicentini Leonardo , Dalino Ciaramella Paolo , Lombardi Giovanni , Corbetta Sabrina

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 ...

Renal complications in patients with chronic hypoparathyroidism receiving conventional therapy: A systematic literature review

Gosmanova Elvira , Houillier Pascal , Bilezikian John , Marelli Claudio , Rejnmark Lars

Conventional therapy for chronic hypoparathyroidism is oral calcium and active vitamin D; despite treatment, chronic hypoparathyroidism may be associated with increased risk of renal complications. Without the effect of parathyroid hormone on renal tubular reabsorption, calcium-conserving and phosphaturic effects are lost, serum calcium levels are reduced and serum phosphate levels are increased. This may lead to hypercalciuria and hyperphosphataemia, which may be associated w...

An enlarged parathyroid gland emerging in the bed of the thyroid may mimic local recurrence in patients after total thyroidectomy for the papillary thyroid cancer: How does recovery from postsurgical hypoparathyroidism work?

Godlewska Paulina , Długosińska Joanna , Bakuła-Zalewska Elwira , Chojnowski Marek , Dedecjus Marek

Anatomical proximity, common blood supply and variability of location of the parathyroid glands make them prone to damage in the course of thyroid gland surgery. Total thyroidectomy (TT) poses a greater risk of postsurgical hypoparathyroidism (hypoPT) than a unilateral lobectomy, and neck lymph nodes dissection is an established risk factor of HypoPT. HypoPT lasting longer than 6–12 months postoperatively is considered permanent. The mechanism responsible for the recover...
