Abstract Objecti¨ e: To look at the modification in depressive mood in postmenopausal depressed women after estrogen replacement therapy ŽERT.. Method: Twelve depressed patients divided into two groups of six women each were studied. One group received conjugated equine estrogens ŽCEE. 0.625 mgrday; the other did not receive any treatment Žcontrol group.. Mood was assessed in all the subjects at baseline and at 6 months with Hamilton Rating Scale score and considered as depression when it was ) 15. Differences between groups were determined by Mann]Whitney U-test, and in each group between baseline and 6-month values with Wilcoxon test. Results: The ERT group had a statistically significant decrease in depressive mood Ž21 vs. 13 points, P- 0.03., while in the control group no significant change was found. Final Hamilton scale scores were significantly lower Ž P- 0.05. in those under ERT, when compared with those in the control group. Conclusion: Depressive mood decreased after 6 months with CEE, so the prescription of ERT can be useful in postmenopausal women with depressive mood.

1. Introduction During climactery, physical and psychological changes occur, the latter includes anxiety, irritability and depression w1x. It is difficult to evaluate which symptoms depend on hormonal disturbances, and which are due to the aging process w2x. Psychological re-adjustments occur in most of the women after the fourth decade of life w2]4x. Depression in women during perimenopause has been described to be as high as 35% w5x. An epidemiological study has shown that the incidence of depression in postmenopause was not higher due to hormonal causes, but it can be due to other stimuli, such as family problems, that may trigger the problem w6x. Women with previous affective disorders related to reproductive events, are at increased risk at menopause w7x. However, other authors have suggested an increase in psychological symptoms during the perimenopause w5,8x, particularly in those at risk for depressive recurrences w9x. Affective disturbances have been related with changes in amine production, principally noradrenaline in the limbic system w10x. Biochemical and pharmacological studies have shown that estrogen levels modify the synthesis and metabolism of cerebral catecholamines w2,3x. Hypothalamic noradrenaline metabolism is diminished by estrogen w10x, and a similar situation occurs with dopamine w11x. Serotonin level increases after estrogen administration w12x, and monoamine-oxidase ŽMAO. seems to be modified by gonadal hormones, as suggested by the inhibitory action of estrogens over the MAO w13x. Estrogen use for postmenopausal depressive symptoms has had variable results, some studies conclude that estrogen has a beneficial effect w14]16x, others indicated that this effect is only seen after a long-term treatment w17x, and another has found that it seems to be dose-related w18x. So the objective of the present work was to look how depressive mood is modified after estrogen replacement therapy ŽERT. with conjugated equine estrogens ŽCEE. in postmenopausal women.
2. Materials and methods Twelve hysterectomized postmenopausal women, 40 years of age and older, who were not receiving nor had received HRT were studied. All had serum levels of follicle stimulating hormone ŽFSH. and estradiol ŽE 2 . measured. Mood was assessed with the Hamilton Rating Scale at baseline and after a 6-month follow-up period w19,20x, ‘depressed mood’ was defined as a score higher than 15 points. Both a FSH level ) 30 mIUrml and Hamilton rating scale score ) 15 were required to be included in the study. They were divided in a non-blind manner into two groups of six women each; one received CEE in a continuous daily dose of 0.625 mg p.o. for 6 months. The control group did not receive any ERT due to medical contraindication or patient personal decision. No cross-over was done during the study. Before the study began, age Žyears., body mass index ŽBMI, weight in kgrheight in m2 . and the waist]hip ratio ŽWHR, waist perimeter in cmrhip perimeter in cm. were analyzed. The number of pregnancies, deliveries, abortions and cesarean sections were also investigated. Differences between both groups were assessed with the Mann]Whitney U-test, and those in each group between baseline and after treatment scores with Wilcoxon test. The study was approved by the Ethics Committee of the ‘Luis Castelazo Ayala’ Gynecology and Obstetrics Hospital, from the Instituto Mexicano del Seguro Social in Mexico City, and the patients gave their informed consent to participate. 3. Results Clinical characteristics of both groups are shown in Table 1. There were no statistical differences between them in age, BMI, WHR, pregnancies, deliveries, abortions, cesarean sections, FSH and E 2 levels. Baseline Hamilton scores did not show any difference between the groups. Comparison in each group between baseline and 6-month posttreatment Hamilton scores, showed a statistically significant decrease in those of ERT group Ž21 vs. 13, P- 0.03., while in the control group, there

were no changes Ž22 vs. 22.. Comparison between groups at 6 months showed significantly lower Hamilton scale scores in the group with ERT Ž22 vs. 13, P- 0.05. ŽTable 2.. 4. Discussion In this study, the effect of ERT on menopause-associated depressive mood, was evaluated with an objective instrument, the Hamilton Rating Scale w19,20x. Depressive mood significantly decreased in women treated with CEE, as has been reported w14x. Also, there was a significant difference between treated and untreated groups in final Hamilton scores. The beneficial effect of ERT was evident at 6 months after the beginning of treatment, which disagrees with a previous report that indicates Table 2 Hamilton scores in two groups of postmenopausal women

that a longer time is needed to observe a beneficial effect w17x. With the daily 0.625-mg CEE dose, changes were observed, in disagreement with other study in which a daily dose of 1.25 mg of CEE was needed to correct the depressive mood w18x. One study has attributed the changes in depressive mood after ERT to the decrease in other climacteric symptoms w16x. Another study reported a greater frequency of depression in those under HRT, but as they explain, it could have been due to a selection bias, so a greater number of depressed women look for help w17x. If depressive symptoms are detected in the absence of other climacteric complaints, other specific anti-depressive therapy must be considered as the first treatment choice w7x. Long-term studies are needed to verify if this response is maintained, and also to look for other possible related factors, that are independent of hormonal status. The effect of progestin addition must also be investigated. In postmenopausal women with depressive mood and climacteric symptoms, ERT with CEE can be helpful, and it might be tried before any other anti-depressive drug is used. Acknowledgments To Martha E.
