Estrogen metabolism in hyperthyroidism and in cirrhosis of the liver
Abstract:
Estrogen metabolism was studied in spontaneous hyperthyroidism (Graves disease) and in alcoholic cirrhosis of the liver. The plasma concentration of estradiol-17beta (PCE2) was increased in men with hyperthyroidism. Although the metabolic clearance rate of estradiol-17beta (MCRE2) was reduced, the production rate (PR) of the steroid was increased above normal. The MCRE2 was also decreased in women with hyperthyroidism but the PCE2 and PRE2 was unchanged from normal. The conversion ratio of estradiol-17beta (CRE2E1) was increased in both hyperthyroid men and women. The PCE2 was significantly increased in men with cirrhosis of the liver. The MCRE2 was normal and this resulted in an increase in the PRE2 in this disorder. The CRE2E1 was significantly higher than normal. The plasma concentration of estrone (E1) was elevated in men with both disorders.
