RESUMEN
The aim of the present study was to assess the prevalence of osteoporosis in a sample of 32 patients with spontaneous primary ovarian insufficiency (POI) in comparison to reference groups of 25 pre- and 55 postmenopausal women. Hip (lumbar) and spinal bone mineral density (BMD) measurements were performed by dual-energy X-ray absorptiometry in the three groups. The median age of POI patients at the time of diagnosis was 35 years (interquartile range: 27-37 years). The mean ± SD age of postmenopausal reference women (52.16 ± 3.65 years) was higher than that of POI (46.28 ± 10.38 years) and premenopausal women (43.96 ± 7.08; P = 0.001) at the time of BMD measurement. Twenty-seven (84.4 percent) POI women were receiving hormone replacement therapy (HRT) at the time of the study. In the postmenopausal reference group, 30.4 percent were current users of HRT. Lumbar BMD was significantly lower in the POI group (1.050 ± 0.17 g/cm²) compared to the age-matched premenopausal reference group (1.136 ± 0.12 g/cm²; P = 0.040). Moreover, 22 (68.7 percent) POI women had low bone density (osteopenia/osteoporosis by World Health Organization criteria) versus 47.3 percent of the postmenopausal reference group (P = 0.042). In conclusion, the present data indicate that BMD is significantly lower in patients with POI than in age-matched premenopausal women. Also, the prevalence of osteopenia/osteoporosis is higher in POI women than in women after natural menopause. Early medical interventions are necessary to ensure that women with POI will maintain their bonemass.

We investigated the presence of mutations/polymorphisms in the FSH receptor (FSHR) gene and their association with phenotype in women with premature ovarian failure (POF) in southern Brazil. Clinical and hormonal variables were determined in 36 46,XX women with primary or secondary amenorrhea before the age of 40 yr, FSH >40 IU/l and ovarian failure. DNA was isolated from peripheral leukocytes. Exons 6, 7, 9, and 10 of the FSHR gene were analyzed by PCR, restriction enzyme analysis, denaturing gradient gel electrophoresis, and direct sequencing. No inactivating mutations were found. Exon 10 had two polymorphisms, Ala307Thr and Ser680Asn (allelic frequency: 52.9 and 35.7%, respectively), which were not related to FSH, LH or estradiol serum levels. Ovarian size and small ovarian follicles on transvaginal sonography were not associated with FSHR genetic variants. In contrast, the last menstruation occurred significantly earlier in patients with the Ala307Thr polymorphism (A: age=33.3+/-7.1 yr vs T: 28.6+/-11.4 yr, p=0.04). In conclusion, we did not identify inactivating mutations in exons 6, 7, 9, and 10 of the FSHR gene. A high frequency of two polymorphisms that are in linkage disequilibrium was found in exon 10 of the FSHR gene. The presence of the Ala307Thr polymorphism may be associated with a more precocious onset of clinical disease.

OBJECTIVE: The effects of natural estradiol and progesterone replacement therapy on lipoprotein and cardiovascular parameters were assessed in 20 postmenopausal women with mild to moderate systemic arterial hypertension. DESIGN: After confirming hypertension in the absence of antihypertensive treatment, blood pressure control was achieved by administration of amlodipine at individually adjusted doses. Hormone replacement therapy (HRT) was introduced in a cyclic regimen (21 of 28 days) with percutaneous estradiol (1.5 mg/day) and vaginal micronized progesterone (100 mg/day). RESULTS: Blood pressure and mean heart rate remained unchanged during HRT. Serial echocardiograph scans showed no change in left ventricle mass, but a significant reduction in the thickness of the left ventricular posterior wall was observed. During treatment, patients showed little variation in total cholesterol levels (baseline: 199+/-10 mg/dl, 12 months: 202+/-11 mg/dl), as well as in high-density lipoprotein (53+/-2 to 50+/-3 mg/dl), low-density lipoprotein (122+/-10 to 118+/-11 mg/dl), and triglycerides (111+/-13 to 126+/-13 mg/dl). A subgroup of 10 patients with initial total cholesterol levels >200 mg/dl responded to HRT with a slight but significant decrease of cholesterol levels after 12 months (265+/-10 to 237+/-12 mg/dl, p<0.05, repeated measures ANOVA). HRT did not change mean antithrombin III levels and affected neither plasma renin activity nor aldosterone levels. CONCLUSION: These results suggest that the proposed HRT regimen with percutaneous estradiol associated with low-dose vaginal micronized progesterone could be a safe alternative for postmenopausal women with hypertension at least during the period required to treat menopausal symptoms.

Endometrial response to natural estradiol and low-dose vaginal progesterone replacement therapy was evaluated in 20 postmenopausal women with chronic, mild-to-moderate hypertension. A cyclic hormone replacement therapy (HRT) regimen was used (21/28 days) with percutaneous estradiol (1.5 mg/day) and vaginal micronized progesterone (100 mg/day). Menopausal symptoms decreased and estradiol concentrations increased substantially and remained in the physiological range throughout treatment. Serum gonadotropin concentrations decreased significantly (p < 0.001, Friedman's ANOVA). Bone mineral density increased by 2.1% (p = 0.029) only at the lumbar spine. Endometrial thickness remained unchanged. Breakthrough bleeding or spotting occurred in 18% of cycles in the first 3 months of HRT, 30% in months 4-9 and 22% in months 10-12. Withdrawal bleeding occurred in 40% of cycles in the first 3 months and decreased to 25% in months 10-12. At month 12, there were 11 women with amenorrhea due to endometrial atrophy. Nine women had active endometria (proliferative or secretory) and thus reported vaginal bleeding. No severe bleeding, hyperplasia, or carcinoma was found. Vaginal bleeding was tolerated, and no subject withdrew from the study. Results suggest that this regimen confers endometrial protection and is well tolerated, and can therefore safely be used for at least 1 year by postmenopausal women with hypertension and menopausal symptoms.

A case-control study was conducted searching through 590 diagnostic hysteroscopies in order to identify potential risk factors for endometrial polyps. Case (hysteroscopically positive for endometrial polyps) and control groups were compared for age, parity, cervical polyp, menopausal status, smoking and current use of contraceptive pills. A higher prevalence of endometrial polyps was found among women with a cervical polyp (26.9%) compared to those without a cervical polyp (7.1%, chi(2) = 27.52, p < 0.001). Increased risk of endometrial polyp was found to be associated with age (odds ratio = 1.75 every 10 years, p < 0.001), cervical polyp (odds ratio = 4.83, 95% CI = 2.43-9.52), and menopause (odds ratio = 2.03, 95% CI = 1.12-3.69). After multivariate analysis, only age (adjusted odds ratio = 1.90, p = 0.001) and cervical polyp (adjusted odds ratio = 5.42, p < 0.001) were independent variables still associated with increased risk of endometrial polyps. We conclude that age and cervical polyp are strong, independent risk factors for endometrial polyps.
