A total of 113 women who presented with climacteric symptoms participated in the study. They were randomly allocated to seven groups of 10-27 subjects, who received for 6 mth the following therapies, respectively: conjugated oestrogens (CE) 0.625 mg/day for 21 days + norethisterone (NET) 5 mg/day from day 12 to day 21; CE + cyproterone acetate (CPA) 12.5 mg/day from day 1 to day 10; oestradiol valerate (EV) 2 mg/day for 21 days + NET; EV + CPA; oestriol (E3) 2-4 mg/day; tibolone (ORG OD14) 2.5 mg/day; and placebo, one tablet/day. Hot flushes decreased significantly over the treatment period in all seven groups. However, E3 was less effective at the dose used than CE, EV or ORG OD 14. At the end of the 6 month treatment period histological examination revealed no changes in endometrial morphology in any of the patients treated. Indeed, the addition of a progestogen even induced regression of endometrial hyperplasia in 8 cases. No significant variation in the plasma levels of triglycerides, total cholesterol, high-density lipoprotein (HDL) or low-density lipoprotein (LDL) was observed after the second and sixth months of treatment with E3 or ORG OD 14. After 6 months, treatment with CE/EV + CPA produced a significant increase in HDL, while treatment with CE/EV + NET brought about a reduction in total cholesterol and HDL and an increase in LDL.
