Plasma-estrogens and liver cirrhosis

Area of Science:

• Endocrinology
• Hepatology
• Androgen and Estrogen Metabolism

Background:

• Male patients with fatty liver, chronic hepatitis, and cirrhosis exhibit altered plasma estrogen and testosterone levels.
• Hepatic cirrhosis is associated with clinical signs of hyperestrogenism and hypoandrogenism.

Purpose of the Study:

• To determine plasma estrogen concentrations and their relationship with testosterone in male liver disease patients.
• To investigate the contribution of adrenal glands and testes to elevated estrogens using stimulation and suppression tests.
• To evaluate the effects of testosterone application in alcohol-induced cirrhosis patients.

Main Methods:

• Measurement of plasma estrogen and testosterone concentrations.
• Hormonal stimulation and suppression tests to assess adrenal and testicular contributions.
• Analysis of androgen to estrogen conversion rates and the impact of testosterone therapy.

Main Results:

• Enhanced peripheral conversion of androgens to estrone, not estradiol, sustains plasma levels in hepatic cirrhosis.
• Plasma levels show increased estrogens and decreased total and free testosterone in male cirrhotic patients.
• The ratio of heterosexual hormones is significantly shifted towards estrogens in hepatic cirrhosis.

Conclusions:

• Hormonal imbalances in male hepatic cirrhosis patients are partly due to increased estrogens and decreased testosterone.
• Peripheral conversion of androgens plays a crucial role in altered hormone levels in liver cirrhosis.
• Clinical manifestations of hyperestrogenism and hypoandrogenism in cirrhosis are linked to these hormonal shifts.
