[Study of calcitonin and parathyroid hormone in patients with bronchial asthma with steroid-induced osteoporosis].

The results of studying calcitonin (CT) and parathyroid hormone (PTH) in patients suffering from bronchial asthma with steroidal osteoporoses are described. Radioimmunoassay was used to measure the content of CT and PTH in 21 patients with corticoid-dependent bronchial asthma complicated by the development of steroidal osteoporosis. A group of patients suffering from bronchial asthma not treated with corticosteroid drugs served for control purposes. Analysis of the data demonstrated a significant (P less than 0.001) decrease of CT level and elevation of blood PTH content in patients with steroidal osteoporoses as compared with the control group.
