[The lipid metabolic characteristics of patients with thyroid pathology living in the European north of the USSR].

The blood content of total lipids, triglycerides, total cholesterol, alpha- and beta-lipoprotein cholesterol was measured in 79 patients with diffuse toxic goiter during treatment, in 25 patients with hypothyroidism, in 33 with thyroid hyperplasia, and in 54 healthy women aged 35-60 years from the group of native population of the European North. In all the forms of thyroid dysfunction, the patients manifested dyslipoproteinemia in the form of hypercholesterolemia with an increase of the concentration of beta-cholesterol, hypertriglyceridemia, and with a rise of the cholesterol atherogenic index to 4.0 and over. The signs of dyslipoproteinemia were marked to the greatest degree in thyrotoxicosis, at the stages of euthyroidism attainment or disease remissions.
