[Cholesterol level in the blood serum and some indices of protein metabolism in patients with endemic hyperplasia of the thyroid gland of stages I and II in the presence of chronic foci of infection].

Chronic foci of infection, and primarily an inflammatory affection of the biliary system revealed in 58.3 per cent of persons with endemic hyperplasia of the thyroid gland of the I and II degree promoted an increase in cholesterolemia and caused a more pronounced (than in the absence of focal infection) reduction in the albumin level and increase in the blood serum globulin fractions. Chronic foci of infection can be regarded as one of the causes of a change of endemic hyperplasia of the thyroid gland into endemic goiter and of the euthyroid state--into hyperthyroid.
