To evaluate the effects of transdermal hormone replacement therapy (HRT) on plasma viscosity, serum levels of thromboxane B2 (TXB2) and vascular impedance in the uterine, bladder wall, internal carotid and ophthalmic arteries in normotensive and hypertensive postmenopausal patients.Thirty postmenopausal patients underwent continuous estradiol transdermal supplementation at a dose of 50 microg/day and 12-day courses of medroxyprogesterone acetate 10 mg/day every 2 months. The women were divided into two groups according to their blood pressure: normotensive women (Group 1, n=14) and hypertensive subjects (Group 2, n=16). Before starting HRT and after 6 months of therapy, the patients underwent: transvaginal ultrasonographic examination of the pelvic organs; Doppler examination of the blood flow velocities in the uterine, bladder wall, internal carotid and ophthalmic arteries; and analysis of plasma viscosity and plasma TXB2.After 6 months of HRT plasma viscosity had decreased in both groups (mean reduction in Group 1, (14+/-1)%, P=0.005; mean reduction in Group 2, (10+/-1)%, P=0.005) as had the TXB2 levels (mean reduction in Group 1, (93+/-2)%, P0.001; mean reduction in Group 2, (92+/-3)%, P0.001). The mean percentage reduction in plasma viscosity was smaller in hypertensive women than in normotensive women (P0.05). There was also a significant reduction in vascular impedance in the uterine artery (mean reduction in Group 1, (16+/-1)%, P=0.005; mean reduction in Group 2, (19+/-1)%, P=0.005), the bladder wall arteries (mean reduction in Group 1, (23+/-2)%, P=0.005; mean reduction in Group 2, (18+/-1)%, P=0.005), the internal carotid artery (mean reduction in Group 1, (25+/-1)%, P=0.005; mean reduction in Group 2, (26+/-1)%, P=0.005) and the ophthalmic artery (mean reduction in Group 1, (24+/-2)%, P=0.005; mean reduction in Group 2, (16+/-1)%, P=0.005). The percentage reduction in vascular impedance did not differ significantly between the two groups.Our results show that transdermal HRT is effective in reducing plasma viscosity, TXB2 levels and vascular impedance in the peripheral and central vessels both in normotensive and hypertensive postmenopausal patients.

To compare the plasma thromboxane, the plasma viscosity and the Doppler flow modifications induced by tibolone and by oral or transdermal continuous combined hormone replacement therapy.Forty-two post-menopausal patients underwent either on: oral daily treatment with tibolone (2.5 mg) (Group I; n= 14); or continuous oral administration of 0.625 mg conjugated equine estrogens + medroxyprogesterone 5 mg per day (Group II; n = 14 ); or continuous estradiol transdermal supplementation, at a dose of 50 microg per day, + medroxyprogesterone 5 mg per day (Group III; n = 14 ). The duration of the study was 6 months and the patients were submitted to transvaginal ultrasonographic evaluation of pelvic organs; Doppler analysis of the uterine, internal carotid and ophthalmic arteries; thromboxane and plasma viscosity assays in basal condition, and at 1, 3 and 6 months from the beginning of the study.Although the endometrial thickness increased significantly, there were no cases in which it exceeded the normal range (or = 5 mm). In all the three groups, the pulsatility index of the uterine, internal carotid and ophthalmic arteries significantly decreased during the therapy showing a reduced impedance since the first month of treatment. Similar variations were observed for the peak systolic blood flow velocity of the internal carotid and ophthalmic arteries. Hormone replacement therapy and tibolone induced a deep, significant and rapid decrease in plasma thromboxane and plasma viscosity levels.Hormone replacement therapy and tibolone seem to have beneficial effects on vascular and hemorrheological parameters.

Phalangeal osteosonogrammetry was introduced as a method for bone tissue investigation in 1992. It is based on the measure of the velocity of ultrasound (amplitude-dependent speed of sound [AD-SoS]) and on the interpretation of the characteristics of the ultrasound signal. In this study we have collected a database of 10,115 subjects to evaluate the performance of AD-SoS and to develop a parameter that is able to quantify the signal characteristics: ultrasound bone profile index (UBPI). The database only includes females of which 4.5% had documented vertebral osteoporotic fractures, 16% lumbar spine dual X-ray absorptiometry (DXA), and 6% hip DXA. The analysis of the ultrasound signal has shown that with aging the UBPI, first wave amplitude (FWA), and signal dynamics (SDy) follow a trend that is different from the one observed for AD-SoS; that is, there is no increase during childhood. In the whole population, the risk of fracture per SD decrease for AD-SOS was odds ratio (OR) 1.71 (CI, 1.58-1.84). The AD-SoS in fractured subjects was significantly lower than in a group of age-matched nonfractured subjects (p0.0001). In a small cohort of hip-fractured patients UBPI proved to be lower than in a control age-matched group (p0.0001). When the World Health Organization (WHO) working group criteria were applied to this population to identify the T score value for osteoporosis, for AD-SoS we found a T score of -3.2 and for UBPI we found a T score of -3.14. Sixty-six percent of vertebral fractures were below the AD-SoS -3.2 T score and 62% were below UBPI -3.14. We observed the highest incidence of fractures (63.6%) among subjects with AD-SoS who had both DXA T score values below the threshold. We conclude from this study that ultrasound investigation at the hand phalanges is a valid methodology for osteoporosis assessment. It has been possible to quantify signal changes by means of UBPI, a parameter that will improve the possibility of investigating bone structure.

The authors evaluated the diagnostic effectiveness of a triple specimen technique (cyto-histologic) performed by the Perma device. The incidence of endometrial hyperplasia (according to Dallenbach-Hellweg's classification) was estimated in 254 climacteric women selected from outpatients who come spontaneously to the Menopause Clinic of the Obstetrics and Gynecology Department (Bologna University). The selection criterion was the evidence of risk factors for endometrial carcinoma, climacteric bleedings (obesity, late menopause, high blood pressure, diabetes), or endometriotropic estrogen therapy in the postmenopause. Results showed that the cyto-histologic sampling is most useful for diagnosing endometrial hyperplasia and early carcinoma (diagnostic effectiveness: 89.0-93.8%). Also, endometrial hyperplasia was found to have a significant incidence in the group we examined. This incidence was highest in women with climacteric bleedings, secondly in women using high-dose estrogens, and thirdly in women with risk factors for endometrial carcinoma. When evaluating the different kinds of endometrial hyperplasia, we never found adenomatous hyperplasia in women on estrogen therapy. Affinity between histologic and cytologic classes was around 50% in endometrial hyperplasia and 100% in early carcinoma. This emphasizes that both samplings are needed to perform an accurate diagnosis.

The Women's Health Questionnaire has been developed and validated in Anglo-Saxon and Swedish populations. The purpose of this study was to evaluate the Italian version of the questionnaire to determine whether cross-cultural differences exist in the perception of quality of life, and to use it to compare the quality of life in women attending menopause centers with that of women in the general population.An Italian version of the Women's Health Questionnaire (WHQ) was produced, using the forward-backward translation method to ensure conceptual equivalence, and approved by the originator. Women were recruited by random selection from the general population and from menopause centers, those taking hormone replacement therapy being ineligible. The questionnaire was completed anonymously at home and mailed to the co-ordinating center. Psychometric evaluation included tests of item convergent and discriminant validity, internal-consistency reliability, test-retest reliability, construct validity and the discriminative properties of the questionnaire.The completeness of the data was good, with missing-value rates consistently low for most items. Item-scale correlations, used to evaluate internal consistency, were also good and the scaling success rate, used to measure item discriminant validity, was high for all scales. Scale scores were reliable for seven out of nine scales and test-retest reliability was excellent. There were few significant differences between the two populations of women in most of the WHQ areas. A comparison of Italian data with published data on English women showed great similarity.The Italian version of the WHO is valid and reproducible. The subjective perception of the menopause and its related problems is similar in geographically and culturally different populations.

Objectives: To provide epidemiological data about psychological symptoms derived from a large Italian non-clinical sample, and to investigate the correlation with psychosocial factors. Methods: The study design was a cross-sectional postal survey of a sample of menopausal women recruited from the General Registry Office in Ferrara’s province. Four thousands and seventy-three women were sent a questionnaire designed on the basis of the Women Health Questionnaire (WHQ). Together with the WHQ, women were asked to fill out a personal file to define social status, cultural level, family’s characteristics, recent menstrual cycles, gynaecological history and operations, drug’s assumption, life events in the last year and lifetime depression. Results: Factor analysis resulted in eight clusters of symptoms. Among psychiatric symptoms, three different clusters were identified: depressive symptoms, depressed mood with anxiety symptoms, and anxiety. The cluster “depressive symptoms” was more evident in the postmenopausal period with respect to the premenopausal one. Conclusion: The cluster “depressive symptoms” is significantly different in the premenopausal group with respect to the postmenopausal group , with greater levels of symptomatology in the postmenopausal group . On the contrary, the factor “depressed mood with anxiety symptoms” is present to the same extent in the pre-, peri- and postmenopausal groups. Prior depression is the most predictive variable of subsequent depression in postmenopausal women. Factors related to more pronounced depressive symptoms are number of life events, postmenopausal status, place of residence in rural areas and lower cultural level.

Vaginal innate immunity in response to microbial perturbation is still poorly understood and could be crucial for protection from adverse outcomes. We investigated the relationship between interleukin (IL)-8, IL-1beta and neutrophils in vaginal fluid obtained from 60 healthy women and 51 women who were bacterial vaginosis (BV) positive. Concentrations of IL-8 and IL-1beta were highly correlated with counts of neutrophils in vaginal fluid of the entire population examined (111 subjects). Vaginal IL-1beta concentrations were significantly higher (P0.001) in BV positive women. There was no significant difference in IL-8 levels or number of neutrophils between healthy controls and BV positive women. None of the healthy controls with high neutrophil counts (or =75th percentile, 14 average count per field) had high concentrations of IL-1beta (or =75th percentile, 220 pg/ml), whereas 84% of BV positive women with high neutrophil counts had high IL-1beta concentrations (P0.001). On the contrary, no difference in the percentage of subjects with elevated concentrations of IL-8 (or =75th percentile, 2842 pg/ml) was found between healthy and BV positive women with high numbers of neutrophils (55.5% of healthy versus 53% of BV positive women). Our findings show that BV causes a large increase in IL-1beta concentrations which is not paralleled by an increase in IL-8 concentrations in vaginal fluid, suggesting that BV-associated factors more specifically dampen IL-8 rather than IL-1beta. The lack of an increase in IL-8 may explain the absence of an increase in neutrophil numbers in most women exposed to abnormal vaginal colonization (BV).

Objectives: The aim of this cross-sectional study was to describe QoL in a large sample of women attending menopause centres and compare untreated postmenopausal women and matched HRT users by employing the Women's Health Questionnaire (WHQ) and two generic instruments, the SF-36 and the EQ-5D. Methods: Overall, 2906 women were recruited by 64 menopause centres throughout Italy, of whom 2160 filled in the questionnaire (1093 on HRT and 1067 not on HRT; response rate: 74%). Results: HRT users tended to be younger, healthier and with shorter menopause duration as opposed to non users, while no major socio-economic differences were present. At multivariate analysis, the presence of chronic diseases, low socio-economic status and living in Southern Italy represented the most important predictors of poor QoL. Furthermore, HRT users showed a lower probability of reporting problems in usual activities and pain/discomfort (EQ-5D), role limitations due to emotional problems (SF-36) and anxiety/fears (WHQ). HRT users also showed highly significant better outcomes in those areas that are more directly attributable to hormonal changes of mid age, namely vasomotor symptoms and sexual problems. Conclusions: Although QoL is mainly influenced by socio-economic and cultural factors, HRT has the potential for improving not only symptoms, but also more general aspects of physical and psychological well-being of symptomatic postmenopausal women.

To assess differences in two sequential combined hormone replacement therapy (HRT) products on selected cardiovascular and breast metabolic markers. The products were different concerning the route of administration of estradiol and its combined progestin, either oral or transdermal, and the androgenic properties of progestogens, respectively, dydrogesterone and norethisterone acetate.One hundred and nineteen healthy non-hysterectomized postmenopausal women were included in this open, multi-center, two parallel group trial. They were randomized to a treatment of six 28-day cycles with oral estradiol sequentially combined with dydrogesterone (oE2/D10) or a sequential combination patch of estradiol plus norethisterone acetate (tdE/NETA). At baseline and after six cycles the high-density lipoprotein cholesterol (HDL-C), the sex hormone binding globulin (SHBG) and the total insulin-like growth factor-I (IGF-I) blood levels were determined by a central laboratory. A total of 89 women were compliant to the protocol.After six cycles, a statistically significant difference (P0.001) concerning HDL-C, SHBG and IGF-I levels was found between the two treatment groups. The HDL-C levels were increased in the oE2/D10 group and decreased in the tdE/NETA group, with a final difference of about 0.3 mmol/l. The oE2/D10 treatment induced a sharp increase (about 57 mmol/l) in SHBG levels. IGF-I levels decreased with both the products, but the difference in favor of the oE2/D10 treatment was of about 30 ng/ml. Moreover, patients on tdE/NETA with an IGF-I baseline value below the median showed an increase.Oral estradiol sequentially combined with dydrogesterone, a non-androgenic progestogen, induced positive changes of some cardiovascular (HDL-C) and breast (SHBG and IGF-I) metabolic markers. These effects were significantly different from those obtained with a transdermal estradiol associated to an androgenic progestogen.

The effects of ursodeoxycholic acid on human placental bile acids and bilirubin transporters in intrahepatic cholestasis of pregnancy are still undefined.To evaluate whether ursodeoxycholic acid affects MRP2, MRP3 and MRP4 expression in the placenta.Forty-three pregnant women were enrolled; fourteen subjects had physiological pregnancies. Intrahepatic cholestasis of pregnancy patients were divided into two groups: (i) 13 received ursodeoxycholic acid (20 mg/kg/day) and (ii) 16 untreated. Total bile acid and bilirubin in serum and cord blood were determined in each subject. Multidrug resistance proteins expression (immunoblot, quantitative real-time PCR) was evaluated in placentas collected at delivery. anova test was used for statistical analysis of data.Ursodeoxycholic acid administration significantly improved maternal serum bile acid and cord blood bilirubin and bile acid levels. MRP2 protein and RNA expression was significantly increased in placentas from treated patients compared to controls (P0.001 and P0.01, respectively). MRP3 protein expression was not significantly different between the groups while RNA expression was significantly decreased in treated patients (P0.01). MRP4 did not show significant differences between the groups.Ursodeoxycholic acid administration induces placental MRP2 expression, and reduces bilirubin and bile acid levels in cord blood.

Our aim was to evaluate the prevalence of bacterial vaginosis and decrease in lactobacillus colonization in women 40 years old or older in relation to menopausal status by evaluation of Gram-stained smears. A total of 1,486 smears from Italian Caucasian women aged 40 to 79 years were examined. Women were classified as follows: fertile (regular cycles) ( n = 328), perimenopausal (irregular cycles) ( n = 237), and postmenopausal ( n = 921), including 331 women on estroprogestinic hormone replacement therapy (HRT). The prevalences of bacterial vaginosis (assessed as a Nugent score of ≥7) in fertile (9.8%) and perimenopausal (11.0%) women were not statistically different, whereas the prevalence was significantly lower overall in postmenopausal women (6.0%) ( P = 0.02). Specifically, 6.3% of postmenopausal women without HRT and 5.4% of postmenopausal women with HRT were positive for bacterial vaginosis. The Nugent score system was not adequate for evaluating the normal and intermediate vaginal flora in women over the age of 40 years. High numbers of peri- and postmenopausal women had no lactobacilli and no bacterial-vaginosis-associated microorganisms. This nonpathological absence of lactobacilli in women with a Nugent score of 4 was scored as 4∗, and this group was considered separately from the intermediate flora group. A score of 4∗ was obtained for 2.1% of fertile women, 11.4% of perimenopausal women, 44.1% of postmenopausal women without HRT, and 6.9% of postmenopausal women with HRT. The physiological reduction in lactobacillus colonization of the vagina in postmenopausal women does not cause an increase in bacterial-vaginosis prevalence. Reversion of lactobacillus flora to premenopausal levels due to HRT does not increase the prevalence of bacterial vaginosis in postmenopausal women.
