Abstract

Purpose: In polycystic ovary syndrome (PCOS), ectopic fat accumulation remains debatable. Therefore, intra-abdominal, hepatic, and epicardial fat were compared between PCOS women and body mass index (BMI)-matched controls and their associations with metabolic and hormonal parameters were explored. Furthermore, the performance of echocardiographic epicardial adipose tissue thickness (EATT) and hepatic steatosis measurement using transient elastography-based controlled attenuation parameter (TE-CAP) in screening abdominal visceral adipose tissue (VAT) was originally evaluated.

Methods: Women aged 18-39 years with BMI < 35 kg/m² were recruited. PCOS was defined by the Rotterdam criteria. All participants underwent clinical and laboratory exams, dual-energy X-ray absorptiometry (DXA), TE-CAP, and echocardiography. A receiver operating characteristic curve was applied to evaluate the accuracy and optimal cutoff values of TE-CAP and EATT in predicting DXA-measured VAT.

Results: The study included 35 women with PCOS and 37 controls. PCOS women exhibited higher levels of androgens, insulin resistance (IR) parameters, LDL-cholesterol, triglycerides, VAT, and EATT. VAT correlated with IR and triglycerides, whereas EATT correlated with HDL-cholesterol. In PCOS women aged 18-29, the cutoff values of CAP and EATT for VAT were 198.0 and 3.07, respectively, with CAP showing higher area under the curves (AUC). In PCOS women aged 30-39, the cutoff values were 209.5 and 3.36, respectively, with EATT showing higher AUC.

Conclusion: VAT correlates with more metabolic parameters in PCOS than TE-CAP or EATT. TE-CAP is useful for VAT screening in PCOS patients aged 18-39 years, whereas EATT is effective and outperforms CAP in those aged 30-39 years.

多囊卵巢综合征的内脏脂肪组织、心外膜脂肪和肝脂肪变性:异位脂肪储存和代谢功能障碍研究。
目的:在多囊卵巢综合征(PCOS)中,异位脂肪堆积仍有争议。因此,研究人员比较了多囊卵巢综合征女性和体重指数(BMI)匹配对照组的腹腔内脂肪、肝脏脂肪和心外膜脂肪,并探讨了它们与代谢和激素参数的关系。此外,还对超声心动图心外膜脂肪组织厚度(EATT)和使用基于瞬态弹性成像的受控衰减参数(TE-CAP)测量肝脏脂肪变性筛查腹部内脏脂肪组织(VAT)的性能进行了初步评估:方法:年龄为 18-39 岁、体重指数为 BMI 的女性:研究包括 35 名患有多囊卵巢综合症的女性和 37 名对照组女性。多囊卵巢综合征妇女的雄激素、胰岛素抵抗(IR)参数、低密度脂蛋白胆固醇、甘油三酯、VAT 和 EATT 水平较高。VAT 与 IR 和甘油三酯相关,而 EATT 与高密度脂蛋白胆固醇相关。在 18-29 岁的多囊卵巢综合征女性中,CAP 和 EATT 的 VAT 临界值分别为 198.0 和 3.07,其中 CAP 的曲线下面积(AUC)更高。在 30-39 岁的多囊卵巢综合症女性中,CAP 和 EATT 的临界值分别为 209.5 和 3.36,其中 EATT 的曲线下面积(AUC)更高:结论:与 TE-CAP 或 EATT 相比,VAT 与多囊卵巢综合征中更多的代谢参数相关。TE-CAP可用于18-39岁多囊卵巢综合症患者的VAT筛查,而EATT对30-39岁的多囊卵巢综合症患者有效且优于CAP。

期刊介绍: Well-established as a major journal in today’s rapidly advancing experimental and clinical research areas, Endocrine publishes original articles devoted to basic (including molecular, cellular and physiological studies), translational and clinical research in all the different fields of endocrinology and metabolism. Articles will be accepted based on peer-reviews, priority, and editorial decision. Invited reviews, mini-reviews and viewpoints on relevant pathophysiological and clinical topics, as well as Editorials on articles appearing in the Journal, are published. Unsolicited Editorials will be evaluated by the editorial team. Outcomes of scientific meetings, as well as guidelines and position statements, may be submitted. The Journal also considers special feature articles in the field of endocrine genetics and epigenetics, as well as articles devoted to novel methods and techniques in endocrinology. Endocrine covers controversial, clinical endocrine issues. Meta-analyses on endocrine and metabolic topics are also accepted. Descriptions of single clinical cases and/or small patients studies are not published unless of exceptional interest. However, reports of novel imaging studies and endocrine side effects in single patients may be considered. Research letters and letters to the editor related or unrelated to recently published articles can be submitted. Endocrine covers leading topics in endocrinology such as neuroendocrinology, pituitary and hypothalamic peptides, thyroid physiological and clinical aspects, bone and mineral metabolism and osteoporosis, obesity, lipid and energy metabolism and food intake control, insulin, Type 1 and Type 2 diabetes, hormones of male and female reproduction, adrenal diseases pediatric and geriatric endocrinology, endocrine hypertension and endocrine oncology.
