Conjugated and unconjugated plasma oestrogens in men with chronic alcoholism and in normal men.

The plasma concentrations for unconjugated and conjugated oestrone, oestradiol-17 beta and oestriol, were measured in 25 male patients with chronic alcoholism and 25 healthy male blood donors of the same age. All persons had normal weight and were free of medication. The patients with chronic alcoholism consisted of 15 persons with and 10 without hepatomegaly. Liver biopsy was performed in the persons with hepatomegaly. Unconjugated oestrogens were separated on LH-20 micro columns after extraction with diethyl ether. Oestrogen sulphates were extracted and separated after hydrolysis with sulphatase, and glucuronides were extracted and separated after hydrolysis with glucuronidase. In the patients with hepatomegaly the plasma concentrations of unconjugated oestrone, oestradiol-17 beta and oestriol were significantly increased, and the plasma levels for the same oestrogen sulphates were significantly decreased, whereas a moderate increase was observed for oestriol glucuronide. The patients without hepatomegaly revealed a significantly lower plasma concentration for oestrone sulphate, whereas no difference was seen for the remaining oestrogen components. The ratio oestrone sulphate to oestrone was significantly reduced in both groups of patients. A significant decrease for the ratio oestradiol sulphate to oestradiol and oestriol sulphate to oestriol was seen only in the patients with hepatomegaly.
