Personal use of hormone therapy by postmenopausal women doctors and male doctors' wives in Italy after the publication of WHI trial.

OBJECTIVE: To describe the prevalence of hormone replacement therapy (HT) use by postmenopausal women doctors and doctors' wives in Italy and to explore the relationship between their personal characteristics and HT use. DESIGN: A total of 500 women doctors and 500 men doctors answering on behalf of their female partners were interviewed by a specialised company in the first months of 2003. Questions were meant to explore medical, behavioural and professional characteristics, personal use of HT, reasons for or against HT use and side effects of HT. The distribution of doctors' specialisation (general practitioners (GPs), gynaecologists, medical oncologists) in the sample interviewed was the same as that of the Italian medical community. RESULTS: Overall, 37% of women doctors and 39% of doctors' wives had ever used HT after menopause, of which 64 and 58%, respectively, were current users. The median duration of HT in the past users was 2.7 years for women doctors and 3.7 for doctors' wives. There were wide differences of HT use according to the type of specialisation: gynaecologists were more willing to use HT (56-59%) than GPs (30-31%) or medical oncologists (16-30%). Vasomotor symptoms (68-69%), followed by the prevention of osteoporosis (28-39%), were the main reasons for commencing HT. The main reasons not to take or to stop HT were the absence or resolution of menopausal symptoms. Only 8% of women doctors and 4% doctors' wives stopped HT after the publication of the WHI data. CONCLUSIONS: In Italy, women doctors/doctors' wives personally use HT much more than postmenopausal general population.

Modification of serum IGF-I, IGFBPs and SHBG levels by different HRT regimens.

UNLABELLED: During the menopause, levels of SHBG, IGF-I and IGFBPs are significantly modified by the use of different HRT regimens. OBJECTIVE: The aim of this study is to evaluate the influence of three different HRT regimens on serum levels of SHBG, IGF-I, IGFBP-1 and IGFBP-3 in postmenopausal women. METHODS: 41 postmenopausal women requesting HRT were enrolled in the study. Subjects were divided in three groups according to the therapy assigned; Group A: estradiol 2 mg/day+cyproterone acetate 1 mg/day in a cyclic sequential regimen; Group B: estradiol hemihydrate 2 mg/day plus norethisterone acetate (NETA) 1 mg/day in a continuous combined regimen; Group C: estradiol hemihydrate 1 mg/day plus NETA 0.5 mg/day in a continuous combined regimen. Blood samples were drawn before the start of hormonal treatment and after 6 months of HRT. Levels of SHBG, IGF-I, IGFBP-1 and IGFBP-3 in the serum were measured by means of a specific immunoassay. RESULTS: In group A, a significant increase of SHBG, no change of IGFBPs and a significant decrease of IGF-I were observed; in group B and in group C, no significant variations for any of the parameters were recorded. CONCLUSIONS: The association of cyproterone acetate to oral estradiol determines a significant reduction of IGF-I levels and an increase of SHBG; nevertheless, it does not seem to influence the serum levels of the IGF-I binding proteins. The treatment with oral continuous combined estrogens plus androgenic progestins, at low doses, produces minor, not significant, changes in the circulating levels of IGF-I, SHBG and IGFBPs.
