Abstract
The evidence that catecholestrogens are formed in the brain and exert behavioral effects
in animal models suggests that these steroids might have psychotropic activities.
In the present investigation, the formation and metabolism of catecholestrogens were
studied in depressed patients. Twenty-four-hr urine samples were collected from 6
male patients (59 ± 8 years) with endogenous retarded depression (subtype primary,
endogenous, and recurrent according to Research Diagnostic Criteria) and from 12 male
control subjects (51 ± 4 years). The patients were treated with the monoamine oxidase
inhibitor tranylcypromine (10–40 mg/day for 3–4 weeks). The concentrations of primary
estrogens, 4- and 2-hydroxyestrogens and 2-methoxyestrogens, were measured in the
urine samples after multiple chromatographic separation steps by radioimmunoassay.
In the depressed patients, the excretion rates of 4-hydroxyestrogens were significantly
lower than in control subjects. The ratio 2-methoxyestrogens:2-hydroxyestrogens as
an index for 2-0-methylation was 3.8 ± 1.6 in patients and 1.8 ± 0.7 in controls.
The increased methylation and reduced 4-hydroxylation rates of patients were not affected
by treatment with tranylcypromine though the psychopathological state was improved
by 46%. Therefore, it seemed unlikely that the observed alterations were pathognomonically
relevant in these depressed patients. The alterations in the formation and methylation
of catecholestrogens show that the depressed patients exhibited remarkable metabolic
disturbances. The functional role of these disturbances remains to be clarified.
