Menopausal depression:comparison of hormone replacement therapy and hormone replacement therapy plus fluoxetine

BACKGROUND: To compare the efficacy and safety of hormone replacement therapy (HRT) combined with fluoxetine, with HRT alone, in post-menopausal women suffering from depression. METHODS: A randomized, open-label, parallel trial was applied. HRT was administered to all patients for 2 cycles, with 14 days of estrogen therapy and 14 days of estrogen plus progesterone. Patients who were randomly assigned to the HRT plus fluoxetine group were given fluoxetine in combination with HRT. Hamilton Depression Rating Scale (HAMD), Kupperman Menopausal Index (KMI), and Clinical Global Impressions scale were used to measure the efficacy. RESULTS: One hundred and twenty-three post-menopausal patients with depression were enrolled in the study. Among them, 120 had at least one post-treatment visit and entered into the statistical analysis. The mean total HAMD scores were significantly lower, and the percentages of HAMD score reductions were higher in the HRT plus fluoxetine Group compared with the HRT Group, after at least 3 weeks of treatment, with an average difference of 5 points at the endpoint. The Clinical Global Impression-Severity and Clinical Global Impression-Improvement scores were significantly different in the 2 groups, in favor of the combination therapy. The mean total KMI was significantly lower in the Combination Group compared with the HRT Group, after at least 6 weeks of treatment, with an average 4.5-point difference between the groups. No statistically significant differences were found in most of the adverse events reported in the Combination Group compared with the HRT group, with the exception of 3 symptoms, i.e., dry mouth, loss of appetite, and abdominal distention. They were mild to moderate in severity. Two patients in the HRT group, but none in the combination group, dropped out due to adverse events. CONCLUSION: HRT plus fluoxetine therapy was effective in the treatment of menopausal depression with a satisfactory safety profile.

Effects of Transdermal Estrogen Therapy on Expressions of Estrogen Receptors and T-lymphocyte Apoptosis in Surgically Menopausal Women

Studies have demonstrated estrogen replacement therapy can improve the life quality of surgically menopausal women. However, the mechanisms in this process remain poorly defined. Here we show the effect of transdermal estrogen therapy on expressions of estrogen receptors and T-lymphocyte apoptosis in surgically postmenopausal women. Fifteen surgically menopausal women, 15 naturally menopausal women and 15 young women were chosen in our studies. Peripheral vein blood was collected and serum E2 and FSH levels were assessed using ACCESS. T-lymphocyte apoptosis and the expressions of Fas, FasL and ER subtypes α and β were determined. The serum E2 levels of surgically menopausal woman were significantly higher, and the ＂Improved Kupperman Index＂ and the scores of ＂Menopause Specific Quality of Life Questionnaire＂ in surgically menopausal women were significantly low after ERT. The rates of T-lymphocyte apoptosis and FasL expression in surgically menopausal women were decreased after ERT, but the difference was not significant. The expressions of ERa and ERβ in two menopausal groups were significantly lower than those of the young group. They were both significantly up-regulated after 3 months of ERT. Transdermal ERT could significantly upregulate the serum E2 level, could improve menopausal symptoms and life quality of surgically menopausal women and upregulate ERa and ERβ expressions on T lymphocytes, especially ERp. Thus, the low dose of transdermal ERT may have a protective effect on menopausal women＇s immune function and aging.
