[Calcitonin and calcium content of the blood of patients with thyroid pathology]

The blood calcitonin and calcium content was studied in 38 patients with thyrotoxicosis, 20 subjects with endemic euthyroid goiter and 7 persons with primary hypothyrosis. The blood calcium and calcitorim levels were not changed in males and females with endemic euthyroid goiter in comparison with those of 19 healthy controls. Calcitonin content was markedly decreased in patients with hypothyrosis. Calcium level was significantly increased in males, remaining practically unchanged in females. Calcium and calcitonin levels were dependent on thyrotoxicosis severity. Calcitonin content remained unchanged in moderate thyrotoxicosis and lowered in the severe stage of the disease. The blood calcium level remained unchanged both in males and females suffering from severe thyrotoxicosis and in males with the moderate form of the disease. Calcium content diminished in the blood serum of females with moderate thyrotoxicosis.
