In women premature ovarian failure (POF) is a devastating disease impacting women under the age of 40. This involves a significant decrease in a women's quantity and quality of oocytes, or ovarian reserve (OR). POF can result in long-term physical and psychological health consequences. The earlier treatment can occur to manage this disease, the less likely the individual is going to suffer from the potential consequences. Accurate diagnosis is a critical proponent to ensuring immediate care. A traditional diagnostic marker includes follicular stimulating hormone (FSH). This individual test cannot be used to make a diagnosis in isolation due to the large variability in FSH levels among different women, and throughout a women's menstrual cycle. Anti-Müllerian hormone (AMH) is an alternative diagnostic marker for determining a women's OR. Serum levels of AMH have been shown to be associated with the size of the resting primordial follicle pool. When the levels of AMH are low, this is generally considered to be an indicator of a decline in fertility. In this study, we examined the specificity, sensitivity and accuracy of the FSH assay, against the more recently emerged AMH assay for diagnosing and predicting POR via Receiver Operator Characteristic curve (ROC) analysis.
A total of 60 participants were enrolled in the study. The POF group included 30 infertile women with POF, the infertile control group included 13 women without POF, and the fertile control group included 17 healthy women. Participants were recruited from the Kamal Al-Samarray Hospital in Bagdad city from December 2017 to March 2018. The age of participants ranged from 19-39 years of age. On day 2 of the menstrual cycle, peripheral blood samples were collected from each participant and the serum levels of AMH and FSH were examined using ELISA.
Statistical analysis examining the FSH and AMH assays indicate that measuring AMH levels leads to an increased sensitivity, specificity and accuracy in determining the presence or absence of POF among the control fertile and POF groups. However, when comparing the specificity, sensitivity, and accuracy of AMH to FSH among the POF group and infertile controls, there were no differences among sensitivity, furthermore there was a slight decrease in the accuracy and specificity of AMH compared to FSH.
Our findings indicate that the serum levels of AMH have higher sensitivity, specificity and accuracy in detecting POR than FSH when comparing the POF patients to healthy fertile controls. As the AMH levels have minimal within-menstrual cycle variation they can therefore be assessed whenever necessary, opposed to FSH, in which the levels vary throughout the menstrual cycle. The role of AMH may therefore hold a more useful role in the early diagnosis of POF.
在女性中,卵巢早衰(POF)是一种影响40岁以下女性的毁灭性疾病。这涉及女性卵母细胞数量和质量或卵巢储备(OR)的显著下降。POF会导致长期的身心健康后果。对这种疾病进行治疗的时间越早,个体遭受潜在后果的可能性就越小。准确诊断是确保及时治疗的关键因素。传统的诊断标志物包括促卵泡生成素(FSH)。由于不同女性之间以及女性整个月经周期中FSH水平存在很大差异,因此不能单独使用这一单项检测来进行诊断。抗苗勒管激素(AMH)是用于确定女性卵巢储备的另一种诊断标志物。血清AMH水平已被证明与静息原始卵泡池的大小相关。当AMH水平较低时,通常被认为是生育能力下降的一个指标。在本研究中,我们通过受试者工作特征曲线(ROC)分析,比较了FSH检测与最近出现的AMH检测在诊断和预测卵巢储备功能减退(POR)方面的特异性、敏感性和准确性。
共有60名参与者纳入本研究。POF组包括30名患有POF的不孕女性,不孕对照组包括13名未患POF的女性,生育对照组包括17名健康女性。参与者于2017年12月至2018年3月从巴格达市的卡迈勒·萨马雷医院招募。参与者年龄在19 - 39岁之间。在月经周期的第2天,从每位参与者采集外周血样本,并使用酶联免疫吸附测定法(ELISA)检测血清AMH和FSH水平。
对FSH和AMH检测的统计分析表明,测量AMH水平在确定生育对照组和POF组中是否存在POF时,会提高敏感性、特异性和准确性。然而,在POF组和不孕对照组中比较AMH与FSH的特异性、敏感性和准确性时,敏感性方面没有差异,此外,与FSH相比,AMH的准确性和特异性略有下降。
我们的研究结果表明,与健康的生育对照组相比,在POF患者中,血清AMH水平在检测POR方面比FSH具有更高的敏感性、特异性和准确性。由于AMH水平在月经周期内变化极小,因此与FSH不同(FSH水平在整个月经周期中会发生变化),可以在必要时随时进行评估。因此,AMH在POF的早期诊断中可能具有更重要的作用。
