Mediators have been identified as osteocalcin (OC), which stimulates insulin (IRI) secretion and activity and IRI as bone anabolic factor. Primary hyperparathyroidism (PHPT) stimulates bone turnover, induces osteoporosis and is associated with increased IRI resistance. A positive relationship between OC and IRI sensitivity has been found in PHPT, but no data exist on the relationship b...
