title: Serum levels of calcitonin in Cushing's syndrome.
abstract: Serum levels of calcitonin (CT) were studied in 21 patients with Cushing's syndrome (CS), 18 females and 3 males aging from 16 to 59 years, and in 70 age and sex matched normal subjects. Patients with CS showed CT values significantly lower than those found in controls (9.9 +/- 5.0 pg/ml vs. 15.9 +/- 6.3 pg/ml, mean +/- SD; p less than 0.01), while no difference was observed in total serum calcium and phosphate and calcium corrected for albumin. No correlation between CT and serum calcium and phosphate, serum cortisol and urinary free cortisol was found. It is possible that low CT levels are involved in the pathogenesis of bone loss observed in CS.
