Polycystic ovary syndrome (PCOS) refers to a condition that often has 'poly' liquid containing sacks around ovaries. It affects reproductive-aged females giving rise to menstrual and related reproductive issues. PCOS is marked by hormonal imbalance often resulting in hyperandrogenism. Inflammation is now considered a central manifestation of this disease with several inflammatory biomarkers such as TNF-α, C-reactive protein and Interleukins-6/18 found to be particularly elevated in PCOS patients. Diagnosis is often late, and MRI-based diagnosis, along with blood-based analyses, are still the best bet for a definitive diagnosis. Radiomics also offers several advantages and should be exploited to the maximum. The mechanisms of PCOS onset and progression are not very well known but pituitary dysfunction and elevated gonadotrophin releasing hormone resulting in high levels of luteinizing hormone are indicative of an activated hypothalamic-pituitary-ovarian axis in PCOS. A number of studies have also identified signaling pathways such as PI3K/Akt, NF-κB and STAT in PCOS etiology. The links of these signaling pathways to inflammation further underline the importance of inflammation in PCOS, which needs to be resolved for improving patient outcomes.
多囊卵巢综合征(PCOS)是指一种常在卵巢周围出现多个含液囊袋的病症。它影响育龄女性,引发月经及相关生殖问题。PCOS的特征是激素失衡,常导致高雄激素血症。炎症现被认为是该疾病的核心表现,多项炎症生物标志物,如肿瘤坏死因子-α、C反应蛋白和白细胞介素-6/18,在PCOS患者中显著升高。诊断往往较晚,基于MRI的诊断以及血液分析仍是明确诊断的最佳方法。放射组学也具有多种优势,应充分利用。PCOS发病和进展的机制尚不完全清楚,但垂体功能障碍和促性腺激素释放激素升高导致黄体生成素水平升高,表明PCOS患者下丘脑-垂体-卵巢轴被激活。多项研究还在PCOS病因中确定了PI3K/Akt、NF-κB和STAT等信号通路。这些信号通路与炎症的关联进一步凸显了炎症在PCOS中的重要性,为改善患者预后,这一问题亟待解决。
