多囊卵巢综合征(PCOS)是育龄期妇女常见的一种内分泌代谢性疾病,发病率为5%~10%,其发病机制尚未完全阐明。高雄激素血症是PCOS的突出特点,尤其是卵巢局部的高雄激素环境是导致PCOS的关键原因,因此对高雄激素形成这一特征性改变的研究成为阐明PCOS病因的重点所在。雄激素主要通过激活雄激素受体(AR)来发挥作用,故AR的作用不容忽视,我们着重就雄激素和AR在PCOS发病中的作用作一综述。  相似文献

Background

Polycystic ovary syndrome (PCOS) is a prevalent, complex endocrine disorder characterised by polycystic ovaries, chronic anovulation and hyperandrogenism leading to symptoms of irregular menstrual cycles, hirsutism, acne and infertility. Evidence based medical management emphasises a multidisciplinary approach for PCOS, as conventional pharmaceutical treatment addresses single symptoms, may be contra-indicated, is often associated with side effects and not effective in some cases. In addition women with PCOS have expressed a strong desire for alternative treatments. This review examines the reproductive endocrine effects in PCOS for an alternative treatment, herbal medicine. The aim of this review was to identify consistent evidence from both pre-clinical and clinical research, to add to the evidence base for herbal medicine in PCOS (and associated oligo/amenorrhoea and hyperandrogenism) and to inform herbal selection in the provision clinical care for these common conditions.

Methods

We undertook two searches of the scientific literature. The first search sought pre-clinical studies which explained the reproductive endocrine effects of whole herbal extracts in oligo/amenorrhoea, hyperandrogenism and PCOS. Herbal medicines from the first search informed key words for the second search. The second search sought clinical studies, which corroborated laboratory findings. Subjects included women with PCOS, menstrual irregularities and hyperandrogenism.

Results

A total of 33 studies were included in this review. Eighteen pre-clinical studies reported mechanisms of effect and fifteen clinical studies corroborated pre-clinical findings, including eight randomised controlled trials, and 762 women with menstrual irregularities, hyperandrogenism and/or PCOS. Interventions included herbal extracts of Vitex agnus-castus, Cimicifuga racemosa, Tribulus terrestris, Glycyrrhiza spp., Paeonia lactiflora and Cinnamomum cassia. Endocrine outcomes included reduced luteinising hormone (LH), prolactin, fasting insulin and testosterone. There was evidence for the regulation of ovulation, improved metabolic hormone profile and improved fertility outcomes in PCOS. There was evidence for an equivalent effect of two herbal medicines and the pharmaceutical agents bromocriptine (and Vitex agnus-castus) and clomiphene citrate (and Cimicifuga racemosa). There was less robust evidence for the complementary combination of spirinolactone and Glycyrrhiza spp. for hyperandrogenism.

Conclusions

Preclinical and clinical studies provide evidence that six herbal medicines may have beneficial effects for women with oligo/amenorrhea, hyperandrogenism and PCOS. However the quantity of pre-clinical data was limited, and the quality of clinical evidence was variable. Further pre-clinical studies are needed to explain the effects of herbal medicines not included in this review with current clinical evidence but an absence of pre-clinical data.

BACKGROUND: We assessed reproductive endocrine and metabolic markers in women treated for bipolar disorder over a 2-year time period, controlling for valproate use. METHODS: Twenty-five women ages 18-45 with bipolar disorder underwent longitudinal evaluations. Subjects completed a reproductive health questionnaire and endocrinological exam at baseline. Total and free testosterone, progesterone, LH, FSH, fasting insulin and glucose, and other hormones were measured across the menstrual cycle at baseline and at 2-year follow-up. RESULTS: Ten subjects were currently receiving valproate as a mood stabilizing agent; of the remaining subjects, six received lithium and five received atypical antipsychotics. Of all subjects, 41.7% reported current oligomenorrhea, while 40% reported oligomenorrhea before starting medication. Rates of oligomenorrhea and clinical hyperandrogenism did not differ by medication use. Eighty percent of women had a high homeostatic model assessment of insulin resistance (HOMA-IR) at baseline; all other measures were normal. Over time, all subjects exhibited a significant decrease in luteal phase progesterone and increase in free testosterone concentrations. Valproate use was associated with an increase over time in total testosterone. Baseline values and changes in BMI were similar across groups. LIMITATIONS: Limitations include small sample size and the absence of a control group. CONCLUSION: We confirm our previous observations of high rates of menstrual abnormalities, hyperandrogenemia and insulin resistance in women with bipolar disorder. These results tentatively support the role of valproate in hyperandrogenemia; however, rates of oligomenorrhea and clinical hyperandrogenism did not differ between medication groups.  相似文献

The tumour necrosis factor (TNF)2 allele appears to be linked with increased insulin resistance and obesity, conditions often found in overweight patients with polycystic ovary syndrome (PCOS). The significance of TNFalpha polymorphism in relation to the clinical and biochemical parameters associated with PCOS was investigated in 122 well-characterized patients with polycystic ovaries (PCO). Of these, 84 had an abnormal menstrual cycle and were classified as having PCOS, while the remaining 38 had a normal menstrual cycle and were classified as having PCO. There were a further 28 individuals without PCO (non-PCO) and 108 individuals whose PCO status was undetermined (reference population). The promoter region of the TNFalpha gene was amplified by polymerase chain reaction (PCR), and the presence or absence of the polymorphism at -308 was determined by single-strand conformational polymorphism (SSCP) analysis. The less common TNF allele (TNF2) was found as TNF1/2 or TNF2/2 in 11/38 (29%) of PCO subjects, 25/84 (30%) of PCOS subjects, 7/28 (25%) of non-PCO subjects, and 45/108 (42%) of the reference population. There was no significant difference in the incidence of the TNF2 allele between the groups. The relationship of TNF genotype to clinical and biochemical parameters was examined. In both the PCO group and the PCOS group, the presence of the TNF2 allele was significantly associated with lower glucose values obtained from the glucose tolerance testing (P<0.05). The TNF genotype was not significantly associated with any clinical or biochemical parameter measured in the PCO, PCOS or non-PCOS groups. Thus, the TNFalpha -308 polymorphism does not appear to strongly influence genetic susceptibility to polycystic ovaries.  相似文献

Problem  It has been a matter of controversy whether the polycystic ovary syndrome (PCOS) is actually a causal factor of miscarriages because of the absence of internationally established criteria. We, therefore, in this study investigated whether PCOS and a polycystic ovary (PCO) morphology have predictive value for subsequent miscarriages using new International and Japanese criteria.
Method of study  A total of 195 patients with a history of two consecutive first trimester miscarriages and without abnormal chromosomes in either partner, antiphospholipid antibodies or uterine anomalies, were examined. The prospective pregnancy outcome was compared between patients with and without PCOS, PCO morphology, elevated luteinizing hormone (LH), hyperandrogenism and obesity.
Results  Of a total of 195 patients, 56 (28.7%) miscarried subsequently. Three (1.5%) and 12 (6.2%) were diagnosed as suffering from PCOS by Japanese and International criteria respectively. There was no relation between a diagnosis of PCOS, PCO morphology, elevated LH, free testosterone or obesity and the subsequent miscarriage rate.
Conclusion  A routine test for diagnosis of PCOS is not necessary in patients experiencing recurrent miscarriages because none of the related parameters examined in this study predicted subsequent miscarriage.  相似文献

The objective of this study was to explore whether hyperandrogenism induces epigenetic alterations of peroxisome proliferator-activated receptor gamma 1 (PPARG1), nuclear corepressor 1 (NCOR1), and histone deacetylase 3 (HDAC3) genes in granulosa cells (GCs) of polycystic ovary syndrome (PCOS) women and whether these alterations are involved in the ovarian dysfunction induced by hyperandrogenism. Thirty-two infertile PCOS women and 147 infertile women with tubal blockage were recruited. PCOS women were divided into the hyperandrogenism (HA) PCOS group (n?=?13) and nonhyperandrogenism (N-HA) PCOS group (n?=?19). Sixty female Sprague-Dawley rats were used for PCOS model establishment. In GCs of HA PCOS women, PPARG1 mRNA expression was lower, whereas NCOR1 and HDAC3 mRNA expression were higher than N-HA PCOS women and controls (P?相似文献

Polycystic ovaries (PCO) are detected using ultrasonographyin a proportion of women who do not have clinical symptoms ofthe polycystic ovary syndrome (PCOS). The aim of this studywas to compare the metabolic and endocrine differences betweenwomen with such ultrasound-detected PCO and women with PCOS,and to relate these changes to clinical presentation with particularreference to cycle irregularity. A group of 118 women showingPCO on vaginal ultrasound scan was divided into those who hadno hyperandrogenaemia (n = 21) and those who had increased androgensand a clinical presentation normally associated with PCOS (n= 97). These were compared with a reference group of 26 normalsubjects. Glucose tolerance, lipid concentrations and endocrineprofiles were compared between groups. Apart from higher concentrationsof androgens in the PCOS group, there were no significant differencesbetween the PCO and PCOS groups in either fasting and stimulatedinsulin and glucose or in concentrations of sex hormone-bindingglobulin, gonadotrophins and blood lipids or in ovarian volume.Both PCO and PCOS subjects with cycle irregularity had significantlyhigher concentrations of serum fasting and stimulated insulinindependent of androgens and body mass index than those withnormal cycles. It was concluded that: (i) PCO and PCOS patientshave equivalent disturbances in relation to insulin and glucosemetabolism as well as lipid and lipoprotein disturbances comparedto reference subjects; (ii) higher serum insulin values areassociated with menstrual irregularity in both groups; (iii)ultrasound evidence for PCO predicts similar metabolic sequelaeto PCOS and can therefore be used for studies of the geneticsand long term risks for this condition.  相似文献

BACKGROUND. Distinguishing between ovarian and adrenal causes of androgen excess may be difficult. We have found that women with the polycystic ovary syndrome have supranormal plasma 17-hydroxyprogesterone responses to the gonadotropin-releasing hormone agonist nafarelin. We determined the usefulness of testing with nafarelin to distinguish ovarian causes of hyperandrogenism in women. METHODS. We studied 40 consecutive women with hyperandrogenism who had oligomenorrhea, hirsutism, or acne. All 40 underwent testing with nafarelin, dexamethasone, and corticotropin with measurement of circulating concentrations of gonadotropins and steroid hormones, and 19 underwent ovarian ultrasonography. RESULTS. The plasma 17-hydroxyprogesterone response to nafarelin was supranormal in 23 of the 40 women (58 percent), and the plasma androgen response to corticotropin was elevated in 23; 13 women had both abnormalities. Only one woman had conclusive evidence of a steroidogenic block; she had nonclassic adrenal 21-hydroxylase deficiency. Of the 23 women with abnormal responses to nafarelin, only 11 (48 percent) had elevated base-line serum luteinizing hormone concentrations. Of the 13 women with abnormal responses to nafarelin who underwent ultrasonography, 7 (54 percent) had polycystic ovaries. Peak plasma 17-hydroxyprogesterone concentrations after nafarelin administration correlated closely with plasma free testosterone concentrations after dexamethasone administration (r = 0.75, P less than 0.001). CONCLUSIONS. Approximately half of women with oligomenorrhea, hirsutism, or acne have an abnormal response to the gonadotropin-releasing hormone agonist nafarelin, suggesting an ovarian cause of their androgen excess.  相似文献
