Initial 17beta-estradiol dose for treating vasomotor symptoms.
OBJECTIVE: To compare the efficacy of different doses of 17beta-estradiol (E2) for relief of vasomotor symptoms in menopausal women. METHODS: This was a randomized, double-masked, placebo-controlled, 12-week study in which 333 menopausal women with moderate or severe hot flushes were assigned to treatment with 0.25 mg, 0.5 mg, 1 mg, or 2 mg oral micronized 17beta-E2, or placebo. The number and severity of hot flushes were recorded daily. RESULTS: There was a significant linear correlation between increased dosage of 17beta-E2 and decreased moderate to severe hot flushes per week (P <.001). Rapid reduction in moderate to severe hot flushes was only achieved with 1 and 2 mg, showing a significant difference from placebo at week 4 (P <.05). At week 4, half the women on placebo had reduced moderate to severe hot flushes of at least 52%; the corresponding figures were 56%, 69%, 86%, and 91% for 0.25, 0.5, 1, and 2 mg, respectively. At week 12, all doses except 0.25 mg were significantly better than placebo for reducing moderate to severe hot flushes (P <.001). Although there were no significant differences, twice as many women in the 2-mg group discontinued treatment due to adverse events, compared with the placebo group. CONCLUSION: Oral micronized 17beta-E2 showed a dose-response effect for reducing moderate and severe hot flushes in menopausal women. 17beta-E2 1 mg appeared to be the most useful initial dose.
Plasma precursors of estrogen. III. Conversion of plasma dehydroisoandrosterone to estrogen in young nonpregnant women.
The utilization of plasma dehydroisoandrosterone for estrogen production was studied in 4 normal young nonpregnant women and in one young surgical castrate woman. The mean transfer constant for total conversion to estrogen, [sigma] DE-BU' was 0.0016 of which about one third (0.0005) could be accounted for by conversion of dehydroisoandrosterone first to plasma androstenedione which in turn was converted to estrone. The remaining fractional conversion appeared to result principally in estradiol formation via a pathway probably not involving plasma androstenedione. The conversion of plasma dehydroisoandrosterone to estrogen was similar in the surgical castrate to that observed in the ovulating women. It is concluded that plasma dehydroisoandrosterone is converted to estrogen at extraglandular site(s) but this contribution represents only a minor fraction of total estrogen production in normal young women.
