[Effect of therapy on the levels of immunoreactive calcitonin and parathormone in patients with autoimmune thyroiditis].

Altogether 18 female patients and one male patient with autoimmune thyroiditis aged 17 to 57 were investigated before and during thyroidin therapy. A basal raised level of immunoreactive calcitonin (iCT) was revealed in 4 patients, that of immunoreactive parathormone (iPTH) in 11 patients. The authors discussed the causes of the elevation of iCT and iPTH levels in patients with autoimmune thyroiditis. A transient character of a rise of the content of these hormones was noted. The authors suggested that in raised iCT and iPTH levels assessment of C-cell and parathyroid function should be repeated in patients with autoimmune thyroiditis after compensation of the main disease.
