Abstract
To study the influence of the adrenal gland on plasma estrogen levels in male patients with hepatic cirrhosis, estrone and estradiol were measured under a variety of experimental conditions. Compared to controls, estradiol levels were moderately elevated by 26% (P < 0.05) in patients with hepatic cirrhosis (28.5 ± 5.4 vs. 36.0 ± 4.7 pg/ml plasma; n: 12), whereas estrone levels exhibited a two-to threefold increase under basal conditions (32.5 ± 5.6 vs. 67.8 ± 20.8 pg/ml; P < 0.01). ACTH application resulted in a striking increase in plasma estrone levels in both patients with hepatic cirrhosis and in normal subjects (61.8 ± 27.5 us. 27.3 ± 7.8 pg/ml). During stimulation with ACTH, estradiol levels showed no significant changes. After suppression of the adrenal gland by dexamethasone administered for 5 days, plasma concentrations of estrone and estradiol were found to be reduced. The absolute decrease of estrone was significantly greater in patients with hepatic cirrhosis than in healthy male subjects (35.5 ± 12.6 vs. 21.3 ± 6.0 pg/ml; P < 0.05; n: 8). Estrogen values, however, were still high in patients with hepatic cirrhosis after 5 days of dexamethasone administration (37.1 ± 17.6 pg estrone/ml and 23.9 ± 3.6 pg estradiol/ml plasma). It is suggested that elevated plasma values of estrogens in this disorder may be derived predominantly from adrenal production. Peripheral conversion of androgens to estrone rather than to estradiol appears to be more effective in sustaining plasma levels of estrogens in patients with hepatic cirrhosis.
