Effects of aging and menopause on serum interleukin-6 levels and peripheral blood mononuclear cell cytokine production in healthy nonobese women

Inappropriate interleukin-6 production is thought to play a role in the development of several age-related conditions including atherosclerosis. This study aimed to determine whether aging affects circulating interleukin-6 (IL-6) levels. Healthy, nonobese women (n = 208, 44.5 ± 0.70 years, 22.4 ± 0.17 kg/m²) were categorized into four age groups (22–31, 32–41, 42–51, and 52–63 years; cross-sectional study). Cytokine levels in serum and those produced from peripheral blood mononuclear cell (PBMC) were measured. The oldest group had the highest circulating levels of IL-6 and oxidized low-density lipoprotein (ox-LDL) and higher PBMC production of IL-6, tumor necrosis factor-α (TNF-α), and interleukin-1 alpha (IL-1β). Additionally, significant interactions between age and menopause were found for serum IL-6 (P = 0.024), and TNF-α (P = 0.011) and IL-1β (P < 0.001) produced from PBMCs. Serum IL-6 levels positively correlated with age, waist–hip ratio (WHR), systolic blood pressure, circulating levels of TNF-α, IL-1β, and ox-LDL, and urinary 8-epi-prostaglandin F₂α. Multiple stepwise regression models identified the following factors for contributing to serum IL-6 levels: serum IL-1β, menopause status, WHR, and serum TNF-α in mode I (R ² = 0.302); serum IL-1β, age, serum TNF-α, and WHR (β = 0.197; P = 0.006) in model II (R ² = 0.283). Sub-analysis was performed according to menopausal status. Serum IL-6 levels were positively associated with levels of IL-6, TNF-α, and IL-1β in PBMC supernatants (unstimulated) from postmenopausal women, whereas these were negatively associated in premenopausal women. In conclusion, circulating IL-6 levels may be interactively influenced by age and menopause. Additionally, estrogen deprivation after menopause may enhance PBMC cytokine production in postmenopausal women, resulting in increased IL-6 levels which are closely related to oxidative stress.     

Influence of menopause on adipose tissue clock gene genotype and its relationship with metabolic syndrome in morbidly obese women

Menopausal women exhibit a loss of circadian coordination, a process that runs parallel with a redistribution of adipose tissue. However, the specific genetic mechanisms underlying these alterations have not been studied. Thus, the aim of the present study was to determine whether the development of menopause induces an alteration of the genes that control biological rhythms in human subcutaneous (SAT) and visceral (VAT) adipose tissue, and whether changes in clock gene expression are involved in the increased risk of developing metabolic syndrome (MetS), which is frequently associated with menopause. To this end, VAT and SAT biopsies were taken in pre- (n = 7) and postmenopausal (n = 7) women at similar hours in the morning. RNA was extracted, and a microarray analysis was made. Data were confirmed by quantitative real-time polymerase chain reaction. Western blot and immunohistochemical analysis were also performed. When clock gene expression was compared between both groups of women, data in SAT showed that expression of the core clock gene period3 was significantly higher in postmenopausal women, while casein kinase-1δ, E1A-binding protein and cAMP-responsive element were preferentially expressed in the premenopausal group. In VAT, period2 (PER2) and v-myc myelocytomatosis viral oncogene expressions were significantly higher in the postmenopausal group. Western blot analysis indicated that PER2 and PER3 protein expression was also increased in postmenopausal women. In addition, several genes, including PER2, were differentially expressed depending on whether or not the patient met the MetS criteria. We conclude that menopause transition induces several changes in the genotype of the adipose tissue chronobiological machinery related to an increased risk of developing MetS.

Anti‐Müllerian hormone as a marker of ovarian reserve: What have we learned,and what should we know?

Ovarian reserve reflects the quality and quantity of available oocytes. This reserve has become indispensable for the better understanding of reproductive potential. Measurement of the serum anti‐Müllerian hormone (AMH) level allows quantitative evaluation of ovarian reserve. It has been applied to a wide range of clinical conditions, and it is well established that the measurement of serum AMH levels is more useful than qualitative evaluation based on the menstrual cycle. AMH levels are monitored during infertility treatments; in patients undergoing medically assisted reproductive technology; and in the diagnosis of ovarian failure, polycystic ovarian syndrome, and granulosa cell tumor. It is also useful in the evaluation of iatrogenic ovarian damage. Population‐based studies have indicated a potential role for serum AMH in the planning of reproductive health management. While AMH is currently the best measure of ovarian reserve, its predictive value for future live births remains controversial. Furthermore, there is a serious practical issue in the interpretation of test results, as currently available assay kits use different assay ranges and coefficients of variation due to the absence of an international reference standard. The pros and cons of the serum AMH level as a definitive measure of ovarian reserve merits further review in order to guide future research.

Perceptions and attitudes toward the menopause among middle aged women from Guayaquil, Ecuador

BACKGROUND: Studies reporting the perspective of Latin American women, Ecuador, included, regarding the menopausal phenomena are scarce or lacking. OBJECTIVES: Obtain information regarding the perception and attitudes toward the menopause among middle aged women of Guayaquil, Ecuador. METHODS: Women aged 40 or more, nursing staff members of two major associated teaching hospitals of the Universidad Católica de Santiago de Guayaquil, Ecuador, were surveyed with a structured questionnaire containing items intended to assess women's perception and attitudes toward the menopause. Secondarily level of information related to the menopause was explored. RESULTS: During the study period, 349 women were surveyed of which mean age was 48+/-6.8 years. A 41.3% were postmenopausal, 55% premenopausal and 3.7% had a history of hysterectomy with conserved ovaries. Women more frequently perceived the menopause as a positive event as they agreed that it is a normal (93.7%) and important event (73.6%), that it gives more confidence and maturity (78.8%), that they may fully enjoy sexual relations (74.8%), that there is a relief as the risk of becoming pregnant is null (65.3%) and that life becomes easier and calmer (60.7%). A relatively high rate demonstrated a preoccupying attitude toward the menopause as 79.4% responded to be concerned about it indicating that seeking medical attention was important, moreover, 77.9% responded that health during this phase be taken care of and life styles changed. Less than 50% of surveyed women considered having enough information regarding the menopause whereas a high rate indicated wanting to receive educational sessions related to the menopause. Married and lower educated women were not concerned about the menopause in a higher rate than their counterparts. CONCLUSIONS: Despite the fact that women perceived the menopause as a positive event, displaying a concerned attitude toward it, their related knowledge was low.     

Efficacy and safety of a soy isoflavone extract in postmenopausal women: a randomized, double-blind, and placebo-controlled study

OBJECTIVE: To investigate the efficacy of soy isoflavone on climacteric symptoms in postmenopausal women. DESIGN: In this double-blind, randomized, placebo-controlled study, a total of 80 women (mean age = 55.1 years), who reported 5 or more hot flush episodes per day, were randomized to receive either 250 mg of standardized soy extract (Glycine max AT) a total of 100mg/day of isoflavone (n = 40) or placebo (n = 40). Exclusion criteria included: contra-indication for hormone therapy (HT), chronic gastrointestinal diseases, and users of HT within the preceding 6-months. For 10-months, climacteric symptoms were evaluated using a score card and the menopausal Kupperman index. Compliance and safety were also assessed. At baseline and the end of the study, lipid and hormonal profiles, as well as vaginal, mammographic and ultrasonographic parameters were measured. The t-test, Wilcoxon test and ANOVA were used in the statistical analysis. RESULTS: At baseline, the mean number of hot flushes was 9.6 +/- 3.9 per day in the isoflavone group and 10.1+/-4.9 in the placebo group (p>0.05). After 10 months, there was a significant reduction in frequency of hot flushes among isoflavone users when compared to those on placebo (3.1 +/- 2.3 and 5.9 +/- 4.3, respectively) (p<0.001). Kupperman index mean values showed a significant reduction in both groups. However, soy isoflavone was significantly superior to placebo, in reducing hot flush severity (69.9% and 33.7%, respectively) (p<0.001). Endometrial thickness, mammography, vaginal cytology, lipids and hormonal profile did not change in both groups. No serious adverse event related to isoflavone treatment was reported. CONCLUSIONS: The soy isoflavone extract exerted favorable effects on vasomotor symptoms and good compliance, providing a safe and effective alternative therapeutic for postmenopausal women.     

Healthcare seeking and treatment for menopausal symptoms in the United States

OBJECTIVES: A population-based study was used to describe healthcare seeking behavior for menopausal symptoms and treatment among women 40-65 years old in the United States. METHODS: Participants were recruited into the Menopause Epidemiology Study from the KnowledgePanel(SM), which is selected by random digit dialing and probability sampling from the US population. From this source, 6201 women 40-65 years old were contacted and 4402 women participated. From the 3135 peri- and postmenopausal women, detailed information was obtained on menopausal symptoms, healthcare seeking, medication usage, and symptom relief from the medication. RESULTS: Many women (60%) reported seeking health care for their menopausal symptoms. More than half of these women sought health care in the past 12 months. Vasomotor symptoms were the most frequently reported menopause symptoms across all races/ethnicities, and the most common symptoms discussed with a health care professional. One-third of the women (34%) used only hormone therapies, 12% used complementary and/or alternative medicines, and 16% used both for treatment of menopausal symptoms. CONCLUSIONS: This study has shown that a large number of women consult healthcare providers for menopausal symptoms, indicating these symptoms are bothersome. Yet, in the United States, there is considerable variation in the symptomatology, healthcare seeking, and use of therapies for menopausal symptoms across cultures. To alleviate these symptoms women have tried alternative treatments as well as hormone therapies, yet many women did not get complete relief of specific symptoms.     

Sexual and psychological symptoms in the climacteric years

OBJECTIVES: To provide epidemiological data about psychological and sexual functioning during menopausal transition in a large Italian non-clinical sample, and to investigate their correlation with life events. METHODS: The study design was a cross-sectional postal survey of a menopausal sample of women recruited from the General Registry Office in Ferrara's province. The sample was composed of four thousand and seventy-three women; they were sent a questionnaire designed on the basis of the Women's Health Questionnaire (WHQ). Together with the WHQ, the subjects filled out a personal file to define social status, cultural level, family's characteristics, recent menstrual cycles, gynaecological history and operations, drug assumption, life events in the last year, and lifetime depression. RESULTS: One thousand three hundred and forty-five women provided usable questionnaires. Factor analysis resulted in eight clusters: somatic symptoms, depressive symptoms, depressed mood with anxiety symptoms, cognitive difficulties, anxiety, sexual functioning, vasomotor symptoms and sleep problems. Mood and sexual function were impaired through the menopausal transition, with depressive and sexual symptoms being higher in the post-menopausal group compared to the pre-menopausal one. Therefore, the correlation between the two was greater in the pre- and peri-menopausal period. CONCLUSION: Depressive and sexual symptoms presented greater severity in the post-menopausal group. Both clusters of symptoms were strongly associated with life events. The parallel course of the two clusters could be related with a common pathoplastic action of life events, both on sexual symptoms and on depressive symptoms, occurring right at the time that a woman has to face the transition into menopause.
