The purpose of this study was to verify if a decreased inhibition of PTH secretion (abnormal suppressibility) in response to physiological increment of plasma calcium is present in patients with osteoporosis. The plasma concentration curve of intact PTH 1-84 following an oral calcium load (Pak) has been calculated in a selected population of 38 osteopenic patients (16 males and 22 females) and in a control group of 9 young healthy adults. All the patients included in this study a) had no past or present diseases and medications of potential influence on calcium homeostasis, b) showed a maximal calcemic response to the oral calcium load equal to that of the control group. PTH suppressibility was significantly smaller in the osteoporotic patients (-42% in males and -32% in females) than in the control group (-76%). This abnormal suppressibility of PTH is independent on sex and, in the females, also on postmenopausal estrogen deficiency. These results support the hypothesis that osteoporosis is associated to an altered secretory response of parathyroid glands maybe due to reduced sensitivity of the parathyroid cells to extracellular calcium.
