A study was made of aldosterone (A) level and plasma renin activity (PRA) in 47 patients with hypothyrosis of various degree of severity prior to and during therapy with thyroid drugs. A normal basal A level in the blood plasma was noted, in some patients it was raised or lowered. The following tendency was revealed during therapy with thyroid drugs: in patients with lowered A and PRA levels a rise of these levels was noted during treatment, in raised levels a significant drop was noted. Normal A and PRA basal levels (in most of the patients) showed in the process of treatment diverse tendencies: toward a decrease in the A level and a rise of the PRA level within normal range. The results obtained indicated independent effect of thyroid hormones on A and PRA synthesis. In case of low level of endogenous thyroid hormones as well as exposure to exogenous thyroid hormones changes in the A level were not directly controlled by PRA.
