Composição corpórea, distribuição de gordura e metabolismo de repouso em mulheres histerectomizadas no climatério: há diferenças de acordo com a forma da administração do estrogênio?

Hormonal therapy with estradiol and testosterone implants: bone protection?

OBJECTIVE

To assess bone mineral density (BMD) in postmenopausal women using estradiol and testosterone hormonal implants comparing to that of patients without hormonal therapy.

DESIGN OF THE STUDY

Sixty-one patients were followed in prospective cohort study separated in Group 1, 34 women using implants and Group 2, 27 women without implants and BMD assessment through Dual energy X-ray absorptiometry was conducted in the beginning of follow-up and after 1 year.

RESULTS

The average lumbar spine BMD in Group 1 was 1.123 ± 0.16 kg/m(2) and 1.144 ± 0.18 kg/m(2) after 1 year, p=0.39 and femur BMD was 0.922 ± 0.16 kg/m(2) and 0.957 ± 0.12 kg/m(2) after 1 year of treatment, p=0.076. In Group 2, the initial lumbar spine BMD average was 1.064 ± 0.2 kg/m(2) and after 1 year, 1.001 ± 0.23 kg/m(2), p=0.112 and femur BMD changed from 0.928 ± 0.14 kg/m(2) to 0.881 ± 0.15 kg/m(2) after 1 year, p=0.046.

CONCLUSION

BMD variance between the groups in the period of 1 year showed that the combination of estradiol and testosterone promoted bone protection in post menopausal women.
