Androstenedione

雄烯二酮
  • 文章类型: Journal Article
    在最近的COVID-19大流行期间,废水监测和流行病学重新引起了人们的兴趣。因此,越来越需要在当地人群中标准化废水衍生的病毒载量.化学示踪剂,外源性和内源性化合物,已被证明比生物指标更稳定和可靠的标准化。然而,不同的仪器和提取方法会使比较结果变得困难。这篇综述探讨了目前10个常见人群指标的提取和量化方法:肌酐,去前列腺素,尼古丁,可替宁,三氯半乳蔗糖,安赛蜜,雄烯二酮5-氢吲哚乙酸(5-HIAA),咖啡因,和1,7-二甲基尿酸。一些废水参数,如氨,总氮,总磷,和每日流量也进行了评估。分析方法包括直接注射,稀释和射击,液体/液体,和固相萃取(SPE)。肌酸,安赛蜜,尼古丁,5-HIAA和雄烯二酮已通过直接注入LC-MS进行了分析;然而,大多数作者更喜欢包括SPE步骤以避免基质效应。LC-MS和GC-MS已成功用于定量废水中的前列甾烷醇,其他选定的指标已经用LC-MS成功量化。据报道,在冷冻之前使样品稳定以保持样品的完整性的酸化是有益的。然而,有支持和反对在酸性pH下工作的论据。前面提到的废水参数是快速和容易量化的,但是数据并不总是能有效地代表人口。对于仅源自人类的人口指标的偏好是显而易见的。这篇综述总结了用于废水中化学指标的方法,为选择合适的提取和分析方法提供了依据,并强调了准确的化学示踪数据对废水流行病学的实用性。
    Wastewater monitoring and epidemiology have seen renewed interest during the recent COVID-19 pandemic. As a result, there is an increasing need to normalize wastewater-derived viral loads in local populations. Chemical tracers, both exogenous and endogenous compounds, have proven to be more stable and reliable for normalization than biological indicators. However, differing instrumentation and extraction methods can make it difficult to compare results. This review examines current extraction and quantification methods for ten common population indicators: creatinine, coprostanol, nicotine, cotinine, sucralose, acesulfame, androstenedione 5-hydroindoleacetic acid (5-HIAA), caffeine, and 1,7-dimethyluric acid. Some wastewater parameters such as ammonia, total nitrogen, total phosphorus, and daily flowrate were also evaluated. The analytical methods included direct injection, dilute and shoot, liquid/liquid, and solid phase extraction (SPE). Creatine, acesulfame, nicotine, 5-HIAA and androstenedione have been analysed by direct injection into LC-MS; however, most authors prefer to include SPE steps to avoid matrix effects. Both LC-MS and GC-MS have been successfully used to quantify coprostanol in wastewater, and the other selected indicators have been quantified successfully with LC-MS. Acidification to stabilize the sample before freezing to maintain the integrity of samples has been reported to be beneficial. However, there are arguments both for and against working at acidic pHs. Wastewater parameters mentioned earlier are quick and easy to quantify, but the data does not always represent the human population effectively. A preference for population indicators originating solely from humans is apparent. This review summarises methods employed for chemical indicators in wastewater, provides a basis for choosing an appropriate extraction and analysis method, and highlights the utility of accurate chemical tracer data for wastewater-based epidemiology.

  • 文章类型: Meta-Analysis
    目标:迄今为止,为了全面总结补充雄烯二酮的效果,尚未进行荟萃分析以从随机安慰剂对照试验(RCT)中收集证据.因此,这项研究的目的是对所有RCT进行系统评价和荟萃分析,探索雄烯二酮补充对个体激素的影响,脂质,和人体测量指数。
    方法:我们搜索了五个数据库(WebofScience,Scopus,Embase,PubMed/MEDLINE,和GoogleScholar)使用医学主题词(MeSH)和非MeSH术语的组合。使用随机效应模型,我们将结局总结为加权平均差(WMD),95%置信区间(CI).
    结果:8篇符合条件的文章被纳入荟萃分析。合并效应大小表明雄烯二酮补充对血清雌二醇浓度有显著影响(WMD:20.82ng/ml,95%CI:7.25至34.38,p=0.003),甘油三酯(TG,大规模杀伤性武器:-0.19毫克/分升,95%CI:-0.96,0.57,p=0.000),和高密度脂蛋白(HDL)-胆固醇(WMD:-0.13mg/dl,95%CI:-0.23至-0.03,p=0.009);然而,它对睾酮没有影响(WMD:0.098ng/ml,95%CI:-0.499至0.696,p=0.748),体重(大规模杀伤性武器:0.579公斤,95%CI:-4.02至5.17,p=0.805),体重指数(BMI,WMD:-0.73kg/m2,95%CI:-2.98,1.50,p=0.519),低密度脂蛋白(LDL)-胆固醇(WMD:-0.074mg/dl,95%CI:-0.37至0.22,p=0.622),和总胆固醇(TC,大规模杀伤性武器:-0.15mg/dl,95%CI:-0.49,0.17,p=0.198)。
    结论:这些发现表明补充雄烯二酮可以降低TG和HDL-胆固醇并增加雌二醇浓度。
    OBJECTIVE: To date, no meta-analysis has been carried out to collect evidence from randomized placebo-controlled trials (RCTs) for the purpose of comprehensively summarizing the effect of androstenedione supplementation. Therefore, the aim of this research was to perform a systematic review and meta-analysis of all RCTs that explored the effect of androstenedione supplementation on individual hormonal, lipid, and anthropometric indices.
    METHODS: We searched five databases (Web of Science, SCOPUS, Embase, PubMed/MEDLINE, and Google Scholar) using a combination of medical subject headings (MeSH) and non-MeSH terms. Using the random-effects model, we summarized the outcomes as weighted mean difference (WMD) with 95% confidence interval (CI).
    RESULTS: Eight eligible articles were included in the meta-analysis. The pooled effect sizes suggested a significant effect of androstenedione supplementation on serum estradiol concentrations (WMD: 20.82 ng/ml, 95% CI: 7.25 to 34.38, p = 0.003), triglycerides (TG, WMD: -0.19 mg/dl, 95% CI: - 0.96, 0.57, p = 0.000), and high-density lipoprotein (HDL)-cholesterol (WMD: - 0.13 mg/dl, 95% CI: - 0.23 to - 0.03, p = 0.009); however, it had no effect on testosterone (WMD: 0.098 ng/ml, 95% CI: - 0.499 to 0.696, p = 0.748), body weight (WMD: 0.579 kg, 95% CI: - 4.02 to 5.17, p = 0.805), body mass index (BMI, WMD: - 0.73 kg/m2, 95% CI: - 2.98, 1.50, p = 0.519), low-density lipoprotein (LDL)-cholesterol (WMD: - 0.074 mg/dl, 95% CI: - 0.37 to 0.22, p = 0.622), and total cholesterol (TC, WMD: - 0.15 mg/dl, 95% CI: - 0.49, 0.17, p = 0.198).
    CONCLUSIONS: These findings indicate that androstenedione supplementation can lower TG and HDL-cholesterol and increase estradiol concentrations.

    描述17β羟基类固醇脱氢酶3(17βHSD3)缺乏症的亚裔印度患者,并进行系统评价以确定影响17βHSD3缺乏症引起的46,XY性发育障碍(DSD)中性别角色的因素。
    我们提供了来自我们46,XYDSD队列(N=150;印度西部)的10例17βHSD3缺乏症患者(9例先证者和1例受影响的家庭成员)的表型和基因型数据,并对152例先证者进行了系统评价,从世界文献中确定17βHSD3缺乏症患者性别角色的决定因素。
    在我们的队列中,17βHSD3缺乏症是非遗传性46,XYDSD的第三大常见原因(6%)。五名患者各有青春期前(非典型生殖器)和青春期(原发性闭经)表现。最初有六名患者被抚养为女性,其中两名(青春期前和青春期各一名)改变了性别角色。观察到10种致病分子变体(6种新型)。在系统审查中,最初的男性教养并不常见(10.5%),并且与非典型生殖器有关,较高的睾酮/雄烯二酮(T/A)比率和亚洲血统。在10.3%的最初女性抚养的患者中,性别角色向男性转变,并且与亚洲血统有关,但与青春期雄激素或分子变异严重程度无关。在欧洲血统的患者中尚未报道。
    我们报道了第一个17βHSD3缺乏症的印度病例系列,46,XYDSD的第三个最常见的原因,有六个新的分子变体。注意到在17βHSD3缺乏症中最初以女性饲养的男性初始性别饲养频率和性别角色变化对男性的差异,需要进一步评估潜在的分子机制。
    To describe Asian Indian patients with 17β hydroxysteroid dehydrogenase 3 (17βHSD3) deficiency and to perform a systematic review to determine the factors influencing gender role in 46,XY disorder of sex development (DSD) due to 17βHSD3 deficiency.
    We present the phenotypic and genotypic data of 10 patients (9 probands and 1 affected family member) with 17βHSD3 deficiency from our 46,XY DSD cohort (N = 150; Western India) and a systematic review of 152 probands with genetically proven, index 17βHSD3 deficiency patients from the world literature to identify the determinants of gender role.
    17βHSD3 deficiency was the third most common (6%) cause of non-dysgenetic 46,XY DSD in our cohort. Five patients each had prepubertal (atypical genitalia) and pubertal (primary amenorrhoea) presentations. Six patients were initially reared as female of whom two (one each in prepubertal and pubertal age) changed their gender role. Ten pathogenic molecular variants (six novel) were observed. In the systematic review, initial male sex of rearing was uncommon (10.5%) and was associated with atypical genitalia, higher testosterone/androstenedione (T/A) ratio and Asian origin. Gender role change to male was seen in 10.3% of patients with initial female sex of rearing and was associated with Asian origin but unrelated to pubertal androgens or molecular variant severity. It has not been reported in patients of European origin.
    We report the first Indian case series of 17βHSD3 deficiency, the third most common cause of 46,XY DSD, with six novel molecular variants. Distinct geographical differences in the frequency of initial male sex of rearing and gender role change to male in those initially reared as females in 17βHSD3 deficiency were noted which needs further evaluation for the underlying molecular mechanisms.

    雄烯二酮是一种在男性和女性性腺中产生的甾体激素,以及肾上腺,它以其在雌激素和睾丸激素产生中的关键作用而闻名。雄烯二酮也作为口服补充剂出售,被用来增加睾丸激素水平。被运动员简单地称为“安德罗”,它通常被吹捧为合成代谢类固醇的天然替代品。通过提高睾丸激素水平,它被认为是运动表现的增强剂,建立身体肌肉,减少脂肪,增加能量,保持健康的红细胞,增加性表现。然而,其中一些影响尚未得到科学证明。虽然通常用作健身的补充,它被列为世界反兴奋剂机构禁止的性能增强药物(PED)之一,以及国际奥委会。本文综述了雄烯二酮对健康影响背后的作用机制。和进一步的副作用,包括临床特征,处于危险中的人群,药代动力学,新陈代谢,和毒物动力学。还介绍了药物兴奋剂中雄烯二酮的规定。
    Androstenedione is a steroidal hormone produced in male and female gonads, as well as in the adrenal glands, and it is known for its key role in the production of estrogen and testosterone. Androstenedione is also sold as an oral supplement, that is being utilized to increase testosterone levels. Simply known as \"andro\" by athletes, it is commonly touted as a natural alternative to anabolic steroids. By boosting testosterone levels, it is thought to be an enhancer for athletic performance, build body muscles, reduce fats, increase energy, maintain healthy RBCs, and increase sexual performance. Nevertheless, several of these effects are not yet scientifically proven. Though commonly used as a supplement for body building, it is listed among performance-enhancing drugs (PEDs) which is banned by the World Anti-Doping Agency, as well as the International Olympic Committee. This review focuses on the action mechanism behind androstenedione\'s health effects, and further side effects including clinical features, populations at risk, pharmacokinetics, metabolism, and toxicokinetics. A review of androstenedione regulation in drug doping is also presented.

    The aim of this systematic review is to assess the effect of Berberine (BBR) on women\'s health to provide greater insights about its effect on women with polycystic syndrome for both patients and health care providers. Electronic databases such as PubMed, Web of Science, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched from the base to July 1th, 2019 to identify clinical trials and randomised controlled trials that had explored the effect of BBR on the polycystic syndrome. With regard to the weight and composition body, BBR did not have any significant effect on reducing body weight and conflicting findings had been reported about waist circumference (WC) and body mass index (BMI). However, BBR led to a significant decrease in waist to hip ratio (WHR), profile hormonal insulin resistance (IR), and insulin resistance (HOMA-IR). Further, androstenedione dropped significantly following treatment with BBB. However, BBB did not have a significant effect on follicle stimulating hormone (FSH) and luteinizing hormone (LH).

    BACKGROUND: Polycystic ovary syndrome (PCOS) is a serious endocrinal disorder in women of reproductive age. Hormonal treatment with oral contraceptives, containing estrogen (ethinyl-estradiol, EE) with progestogen (drospirenone, DRSP) or (chlormadinone acetate, CMA), has improved symptoms and biomarkers of PCOS.
    OBJECTIVE: The aim of the present meta-analysis is to compare the effects of EE/DRSP versus EE/CMA on the endocrinal features of women with PCOS.
    METHODS: Several electronic databases were searched for combinations of the following relevant MeSH terms were used: (ethinyl-estradiol OR EE) AND (drospirenone OR DRSP) AND (chlormadinone acetate OR CMA) AND (polycystic ovary syndrome).
    METHODS: Records were screened for eligible studies and data were extracted to an online data extraction form. Outcomes of Ferryman-Gallwey score (FGS), body mass index, dehydroepiandrosterone sulfate (DHEAS), free androgen index, sex hormone-binding globulin, delta-4-androstenedione (A) and total testosterone levels (T) were pooled as weighted mean difference (WMD) and 95% confidence interval (CI) in a fixed effect meta-analysis model.
    RESULTS: Three RCTs (EE/DRSP: n = 98 and EE/CMA: n = 87) were pooled in the analysis. The overall effect favoured EE/DRSP over EE/CMA in reducing (A) levels after three months (WMD -0.63; 95% CI [-0.94, -0.32], P < 0.001), FGS after six months (WMD -0.44; 95% CI [-0.99, -0.19], P = 0.0006), and total (T) after three months (WMD -0.12; 95% CI [-0.23, -0.01], P = 0.03).
    CONCLUSIONS: EE/DRSP showed a more potent effect than EE/CMA in the reduction of FGS after six months, (A) levels and (T) levels after three months in patients with PCOS.

    This meta-analysis aims to investigate serum androgen profiles (testosterone, dehydroepiandrosterone sulfate, androstenedione, and sex hormone-binding globulin) in women with premature ovarian failure and to establish if there is evidence of diminished androgen levels in these women.
    Various Internet sources of PubMed, Cochrane library, and Medline were searched systematically until February, 2018. Out of a pool of 2,461 studies, after applying the inclusion/exclusion criterion, 14, 8, 10, and 9 studies were chosen for testosterone, dehydroepiandrosterone sulfate, androstenedione, and sex hormone-binding globulin, respectively, for this meta-analysis. The effect measure was the standardized mean difference with 95% confidence interval (95% CI) in a random-effects model.
    The testosterone concentrations in premature ovarian insufficiency were compared with fertile controls: stamdard mean difference (IV, random, 95% CI) -0.73 [-0.99, -0.46], P value < 0.05. The dehydroepiandrosterone sulfate concentrations in premature ovarian insufficiency compared to fertile controls: standard mean difference (IV, random, 95% CI) -0.65 [-0.92, -0.37], P value < 0.05. Androstenedione in premature ovarian insufficiency were compared with fertile controls: standard mean difference (IV, random, 95% CI) -1.09 [-1.71, -0.48], P value < 0.05. Sex hormone-binding globulin levels did not show statistical significance. The dehydroepiandrosterone sulfate levels were reduced in premature ovarian insufficiency cases, but still showed a higher level than in postmenopausal women.
    Women with premature ovarian insufficiency are at risk for decreased concentrations of testosterone, dehydroepiandrosterone sulfate, and androstenedione. Dehydroepiandrosterone sulfate levels were more reduced in postmenopausal controls when compared with premature ovarian insufficiency cases.

    OBJECTIVE: A limited number of studies have evaluated the relationship between clinical and biochemical hyperandrogenism (HA). This study aimed to evaluate the association between biochemical hyperandrogenism parameters (BHPs) and Ferriman-Gallwey (FG) score in patients with polycystic ovary syndrome (PCOS).
    METHODS: We searched PubMed, Scopus, Google Scholar, ScienceDirect and Web of Sciences databases (2000-2015) to identify studies investigating clinical and biochemical parameters of HA in PCOS patients. In this meta-analysis, both fixed and random effect models were applied to estimate pooled effect size. To assess the relationships between BHPs and FG score, meta-regression analysis was used.
    RESULTS: Fifty-five study groups with a total of 6593 PCOS patients were analysed. Meta-regression analysis of pooled data from all eligible studies showed significant positive relationships of FG score with androstenedione (A4) (P=.034) and dehydroepiandrosterone sulphate (DHEAS) (P=.012), whereas it showed no association with total testosterone (tT), free testosterone (fT), sex hormone bonding globulin (SHBG) and free androgen index (FAI). The results did not change after adjusting for quality assessment or method of assay. Nor did the associations between A4 and FG score remain after adjusting for age and BMI, diagnostic criteria for PCOS and study design or the association between DHEAS and FG score remain after adjusting for ethnicity.
    CONCLUSIONS: This meta-analysis confirmed the associations of some BHPs, including A4 and DHEAS with FG score, indicating that measurement of these parameters can be useful for managing PCOS patients with hirsutism.

    Deficiency of 17β-hydroxysteroid dehydrogenase type 3 (17βHSD3), an enzyme converting androstenedione (A) to testosterone (T), is a rare cause of autosomal recessive 46,XY disorder of sexual development (DSD). A 18-years phenotypically female patient from southern Italy presented with primary amenorrhea. She had deep voice, macrocephaly, enlarged and bulbous nasal tip, macrostomia, facial acne, breast asymmetry, hypoplasia of the first finger of right hand, proximal implant of the fifth metatarsus bilaterally as well as an increased muscle mass and hirsutism, with hair distribution on face, neck, chest, abdomen, pubic region and on upper and lower limbs. Genital exam showed thickened labra majora with absence of labra minora and a blind-ending pseudo-vagina with clitoris enlargement. Karyotype analysis showed a male genotype (46,XY). Hormonal evaluation showed decreased T (188 ng/dL-6.5 nmol/L) and increased A (10 ng/mL-34,96 nmol/L), considering male reference ranges, resulting in a decreased T/A ratio (0,186). MRI identified testicles in inguinal regions. Human Chorionic Gonadotropin test showed T/A ratio permanently under 0,8. These evidences were suggestive of a 46,XY DSD due to 17βHSD3 deficiency. An homozygous mutation (IVS3 -1 G>C or c.326-1G>C) of the 17βHSD3 gene was discovered. Psychologist identified a well determined female gender identity. It was decided to proceed with gonadectomy and vaginal enlargement by use of dilatators.
    CONCLUSIONS: The case described represents a new case of DSD due to 17βHSD3 deficiency. This patient, raised as a girl, is diagnosed in a very late stage. The identified mutation, previously reported only in Dutch and Brazilian population, is one of 27 presently known mutations of 17βHSD3 gene and is never reported in Italian population.

    Nodular testicular lesions derived from adrenal tissue (testicular adrenal rest tumours - TART) in boys and men with congenital adrenal hyperplasia (CAH) lead to testicular structure damage, spermatogenesis disorders, and infertility. Hyperplasia of the ectopic adrenal tissue in testes is associated with high levels of the adrenocorticotropic hormone (ACTH) in blood serum. The development of non-invasive methods of diagnostic imaging allows detection of testicular lesions in adolescents and children. The basic method for TART detection is imaging with ultrasonography (USG) being the most widely available method. Since these mild testicular lesions can cause impaired fertility, periodic palpation and testicular ultrasonography should be performed in patients with CAH in order to prevent infertility.
