Objectives: To describe and compare acceptability of treatment and quality of life over 12 cycles in 2 groups of women randomised to continuous combined Climodiène (estradiol valerate 2 mg/dienogest 2 mg) or cyclic Climène (estradiol valerate 2 mg, from D1 to D21/cyproterone acetate 1 mg, from D12 to D21, followed by 7 days off), switching from previous sequential estroprogestative HRT because of side effects., Patients and Methods: One hundred forty three postmenopausal women aged 54.39-years were recruited and randomised to Climène (N=68) or Climodiène (N=75). Acceptability was evaluated by the continuation rate in the 2 groups at the end of the 12 cycles study. Assessment of quality of life was obtained from the responses to the women's health questionnaire (WHQ) and to an ad hoc satisfaction questionnaire at baseline, and at the 12th cycle of treatment., Results: No significant difference in baseline characteristics of volunteers were found in the 2 treatment groups except for the socioeconomic status (more town-dwellers in Climène group). Total WHQ score significantly improved after 12 months of treatment with Climène and Climodiène, respectively decreasing from 68.9 to 64.37 (-4.53) and from 69.95 to 62.06 (-7.89), with a trend towards higher improvement with Climodiène, particularly in the hot flushes subscale. In Climodiène group, a significant decrease in sleep problems and cognitive function subscales was found, which is consistent with previous polysomnography and psycho physiological measures data with Climodiène. The evolution of Satisfaction Index is positive and of the same magnitude in the 2 groups, showing an improvement at 12 months: respectively -2.79 (P=0.002) et -2.26 (P=0.02) for Climène and Climodiène., Discussion and Conclusions: Even though the benefit/risk ratio of the hormonal substitutive treatment is recognized effective against climateric symptoms which affect the quality of life, this work is the first randomised prospective study on the effects of Climodiène on quality of life in post-menopausal women assessed by the French validated version of the world-wide used WHQ. Decreases in "sleep problems" and "cognitive function" subscales scores in this study are of a magnitude clinically relevant and consistent with previous data on Climodiène impact on postmenopausal symptoms.

Objective: To compare the effects of a 12-week treatment with 17ss-estradiol given alone and in sequential combination with 3.75 mg of nomegestrol acetate (Naemis), or a placebo on biochemical markers of bone turnover in menopausal women., Patients and Methods: A double-blind, randomized, placebo and estradiol-controlled multicenter study was conducted. A total of 176 patients who had been menopausal for 1-10 years, hysterectomized or not, having no contraindications to hormone replacement therapy, without any risks factors for osteoporosis, received one of these treatments during 12 weeks: placebo, 1.5 mg estradiol (E(2)) or 1.5 mg E(2)/3.75 mg nomegestrol acetate (E(2)/NOMAC). The primary efficacy variables were the change in bone markers (total alkaline phosphatase, bone alkaline phosphatase and osteocalcin; urinary type-I collagen peptides)., Results: The four biochemical markers decreased only in the E(2)/NOMAC group. Bone alkaline phosphatase, osteocalcin and urinary type-I collagen peptides decreased in the E(2) group. For both active treatment groups compared to the placebo group, the changes were statistically significant after a 12-week treatment. There were no statistically significant differences between the E(2) and the E(2)/NOMAC groups except for total serum alkaline phosphatase, whose mean value decreased in the E(2)/NOMAC group but increased slightly in the E(2) group (p < 0.001). Furthermore, after a 6-week treatment, the changes in biochemical markers of bone turnover were similar to those found after 12 weeks. Safety data were satisfactory with regard to estradiol given alone or in combination with nomegestrol acetate., Conclusion: These results demonstrated that 1.5 mg E(2) is effective in reducing bone turnover in postmenopausal women and proved that the combination of 1.5 mg E(2) and 3.75 mg nomegestrol acetate has no deleterious effect on bone remodelling.

The effects of oral micronized progesterone on the endometrium and bleeding pattern have been assessed in a multicenter study of 101 postmenopausal patients. During a minimum of 6 cycles, the participants received either percutaneous 17 beta-estradiol (1.5 mg/day) associated with micronized progesterone (100 mg/day), given at bedtime for 21/28 days or 25 days/calendar month (n = 98) [1], or E2 (3 mg/day) for 25 days associated with progesterone (300 mg/day), from day 16 to day 25 (n = 3) [2], according to their willingness to induce, or not, cyclic withdrawal bleeding. Each endometrial biopsy performed at 6-month minimum was assessed by two independent pathologists: results showed 61% quiescent without mitosis, 23% mildly active with very rare mitoses and 8% partial secretory endometrium. The remaining biopsies showed inadequate tissue (4%) or a sub-atrophy (4%). No hyperplasia was found by any pathologist. In the case of inadequate material, the mean thickness of endometrial mucosa measured by ultrasonography was 3.9 mm. Amenorrhea incidence was 93.3 and 91.6% at the 3rd and 6th month of therapy, respectively. No bleeding occurred in more than 80% of women. The results show that a low dose of oral progesterone (100 mg/day), given during 25 days, efficiently protects the endometrium by fully inhibiting mitoses and induces amenorrhea in the majority of postmenopausal women, allowing better compliance to long-term therapy.
