Efficacy and safety of DT56a compared to hormone therapy in Greek post-menopausal women.

BACKGROUND: Hormone therapy (HT) is the treatment of choice for the alleviation of menopausal symptoms; concerns, however, about its concomitant long-term health risks have limited its use. DT56a is a unique enzymatic isolate of soybeans. The purpose of our study was to evaluate the efficacy and safety of DT56a, compared to HT, in symptomatic post-menopausal women. SUBJECTS AND METHODS: Eighty-nine post-menopausal women were studied prospectively. Women with climacteric symptoms were randomly assigned to receive eitherDT56a (no.=27) or oral low dose continuous combined HT (no.=26). Symptomatic women not wishing to receive any treatment served as controls (no.=36). Menopausal symptoms as assessed through the Kupperman index, serum lipids and lipoproteins, calcium, as well as bone mineral density (BMD), endometrial thickness, and mammography were assessed at baseline and at 12 months. RESULTS: Patients receiving HT and DT56a showed a significant and independent decrease in menopausal symptoms (mean difference in Kupperman score, DT56a group: -3.98, HT group -5.601, no treatment group +1.76, p-value <0.001). Lumbar spine BMD T-score was significantly lower in women receiving no treatment, as opposed to the two treatment arms which showed no significant change (No treatment, baseline: -0.60, final: -0.85, p=0.001; HT, baseline: -84, final -0.99, p=0.79; DT56a, baseline -0.51, final: -0.76, p=0.75). No differences in femoral bone density, ET or mammography classification were detected in any of the treatment arms. Likewise, serum lipids or lipoproteins did not differ between the three groups. CONCLUSIONS: DT56a decreased menopausal symptoms significantly and in the same degree as HT.

Augmentation of cortical bone mineral density in women with polycystic ovary syndrome: a peripheral quantitative computed tomography (pQCT) study.

BACKGROUND: Women with polycystic ovary syndrome (PCOS) may have increased cortical bone mineral density (BMD) and probably higher bone material quality as well as better resistance in the compression strength of the tibia, measured by peripheral quantitative computed tomography (pQCT), in comparison with that of age-matched healthy subjects. METHODS: Thirty women with PCOS, (15 lean and 15 obese) and 15 age-matched healthy controls were enrolled in this study. The clinical, biochemical and ultrasound characteristics of the two groups were evaluated. Using pQCT, the following parameters were measured: volumetric cortical density (CBD) and volumetric trabecular density (TBD) BMD, total bone cross-sectional area (ToA), cortical area (CoA), cortical thickness (CRT-THK-C) and finally the strength-strain index (SSI). RESULTS: The geometrical parameters (CoA, ToA, CRT-THK-C), the SSI as well as the TBD were increased in the PCOS women; however, these differences did not achieve statistical significance between lean PCOS women, obese PCOS women, and controls. Conversely, CBD was significantly higher in PCOS women compared with controls (P < 0.000) and furthermore in lean PCOS women compared with obese ones (P < 0.01040). CONCLUSIONS: The PCOS women of our study seem to have a higher quality of bone material in the distal tibia and probably a better resistance of bone in the compression strength without alterations in bone mass and geometry (especially the lean PCOS women), indicating that our oligomenorrheic and hyperandrogonemic PCOS women may be protected from the development of osteoporosis and fracture risk later in life.

Hemodynamic alterations and wall properties in large arteries of young, normotensive, and non-obese women with polycystic ovary syndrome.

Young, normotensive, and non-obese women with polycystic ovary syndrome (PCOS) may present abnormal hemodynamic alterations (HA). The purpose of this study was to investigate heart rate (HR), intima-media thickness (IMT), and diameter (DCCA) in the common carotid arteries (CCA), flow velocities, and resistance index in both extracranial carotid and vertebral arteries (VA), in the abdominal aorta (AO) and in the renal arteries (RA) in PCOS women and matched controls. This was a case-control study conducted at a tertiary University Hospital. We studied 53 PCOS women and 53 healthy matched volunteers as controls. The previously reported parameters were assessed using color Doppler ultrasonography. HR, IMT in the CCA, and peak systolic velocity in all examined arteries were significantly increased in PCOS women compared to controls. On the contrary, DCCA was significantly decreased in PCOS women compared to controls. End diastolic velocity (EDV) in both VA and RA, in the AO and in the left extracranial carotid system was significantly increased in the PCOS group compared to controls. Furthermore, the peripheral resistance (PR) of AO and right external carotid artery was also found to be increased while in both RA and in left VA, PR was decreased. No further statistical significant HA in EDV and PR were noted. The results of this study provide evidence for a mild hyperdynamic circulation in young, normotensive, non-obese women with PCOS compared to controls, indicating a mild sympathetic activation at an early age, which may be an underlying cause of hypertension and cardiovascular risk.
