[Immunoreactive parathyroid hormone and calcitonin in patients with autoimmune thyroiditis].

The authors presented the results of a study of immunoreactive parathormone and calcitonin in patients with autoimmune thyroiditis. An increase in the content of parathormone in the blood was found in 55.5% of the patients, that of calcitonin in 30.5% of the patients with autoimmune thyroiditis. Correlation between the levels of immunoreactive parathormone and calcitonin in the blood was revealed. A degree of an increase in the levels of parathormone and calcitonin corresponded to the expression of autoimmune reactions in the thyroid. It was proposed that the determination of parathormone and calcitonin be used as an additional criterion in the diagnosis of autoimmune processes in the thyroid and in the determination of their activity.
