We studied calcium and calcium and calcitonin responses to intravenous calcium infusion (3 mg of elemental calcium/kg of body weight in 10 minutes) in 21 type I diabetic males and 17 age-matched normal males. Baseline total calcium, parathyroid hormone and calcitonin levels were normal in the diabetic group, but ionized calcium was lowered. Cortical bone status and osteocalcin levels were normal, suggesting a normal osteoblastic function. Total calcium and ionized calcium responses to calcium infusion were lowered in the diabetic group. Despite these lowered calcaemic responses, calcitonin secretion was normal.
我们研究了21名I型糖尿病男性和17名年龄匹配的正常男性对静脉注射钙剂(10分钟内每千克体重注射3毫克元素钙)的钙、钙和降钙素反应。糖尿病组的基线总钙、甲状旁腺激素和降钙素水平正常,但离子钙降低。皮质骨状态和骨钙素水平正常,提示成骨细胞功能正常。糖尿病组对钙剂注射的总钙和离子钙反应降低。尽管这些血钙反应降低,但降钙素分泌正常。
