BACKGROUND: Adult growth hormone deficiency (AGHD) is associated with osteoporosis. Growth Hormone replacement (GHR) results in increased bone mineral density (BMD), with greater benefit derived in men. PTH plays an important role in bone metabolism and reports suggest that bone and renal insensitivity to PTH may contribute to changes in bone turnover in AGHD.OBJECTIVES: To determine the gender difference in PTH, phosphocalcium metabolism and bone turnov...

BACKGROUND: Adult Growth Hormone Deficiency (AGHD) is associated with reduced bone mineral density (BMD). PTH plays an important role in bone metabolism and reports have suggested target cell insensitivity to PTH as a contributor to the changes in bone turnover seen in AGHD. Although growth hormone replacement (GHR) increases BMD, the underlying mechanisms remain unclear.OBJECTIVES: To determine the effect of GHR on 24-hour PTH profiles, phosphocalcium ...
