BACKGROUND: Acromegaly is associated with abnormal bone metabolism, characterized by increased bone turnover. In health, PTH is secreted in a circadian rhythm, which is important in bone function. However, the effect of acromegaly on PTH secretion is unclear, with previous studies reporting increased, decreased or no change in PTH concentration. Furthermore, the presence of PTH circadian rhythmicity has not been defined in acromegaly.OBJECTIVES: To determine the effect of ...
