摘要

该前瞻性队列纳入70例首次ART不孕女性(32例孤立性ANA阳性、38例ANA阴性对照),对取卵日卵泡液行代谢组与蛋白质组整合分析。ANA阳性组受精率、优质胚胎及囊胚数均显著降低;多组学提示类固醇激素合成、补体凝血、氨基酸和甘油磷脂代谢紊乱。L-苯丙氨酸、SM(d18:1/16:0)和氢化可的松与胚胎发育潜能相关,联合代谢物面板区分ANA状态AUC达0.968,但胚胎结局判别AUC仅0.719~0.771,仍属发现阶段,需独立队列验证。

原文摘要

BACKGROUND: Autoimmune abnormalities are increasingly recognized as contributing factors to unexplained infertility. Among these, antinuclear antibodies (ANAs) are the most frequently detected autoantibodies and have been associated with adverse embryologic outcomes. However, the mechanisms by which isolated ANA positivity (defined as ANA positivity in the absence of anti-extractable nuclear antigen [anti-ENA] antibodies) may influence oocyte developmental competence and early embryonic development remain poorly understood. This study aimed to characterize follicular fluid (FF) molecular alterations associated with isolated ANA positivity using an integrative multi-omics approach. METHODS: In this prospective cohort study, 70 infertile women undergoing their first assisted reproductive technology (ART) cycle were enrolled, including 32 women with isolated ANA positivity (serum ANA ≥ 1:80 and anti-ENA negative) and 38 ANA-negative controls. FF samples collected on the day of oocyte retrieval were subjected to integrated metabolomic and proteomic analyses. Differential expression and functional enrichment analyses were performed, followed by correlation and network analyses to explore associations between FF molecular profiles and oocyte as well as embryo developmental competence. Key metabolites were further evaluated using receiver operating characteristic (ROC) analyses to characterize their exploratory discriminatory performance. RESULTS: Women with isolated ANA positivity showed significantly poorer embryo developmental outcomes than ANA-negative controls, including lower IVF/ICSI fertilization rates and reduced numbers of high-quality embryos and blastocysts (all P < 0.05). After adjustment for potential confounders, multivariate linear regression analysis suggested that isolated serum ANA positivity was independently associated with impaired early embryonic development (P < 0.05). Integrated multi-omics analyses revealed significant dysregulation of pathways related to steroid hormone biosynthesis, immune-related pathways including complement and coagulation cascades, amino acid metabolism, and glycerophospholipid metabolism. Among the identified molecular features, three metabolites-L-phenylalanine, SM(d18:1/16:0), and hydrocortisone-were consistently associated with embryo developmental potential and showed stable correlations independent of ANA titers. A combined preliminary metabolite panel was identified that discriminates ANA-positive from ANA-negative women with excellent discriminatory performance (AUC = 0.968). In exploratory analyses of dichotomized oocyte- and early embryo-related outcomes, the panel showed moderate discriminatory performance (AUCs = 0.719-0.771). CONCLUSIONS: Isolated ANA positivity is associated with metabolic reprogramming in the follicular microenvironment and impaired early embryonic development. The identified exploratory metabolite signatures provide insight into immune-metabolic alterations that may underlie ANA-associated infertility and may inform future prognostic model development. Their associations appeared consistent across the ANA-titer subgroups examined. However, the panel remains preliminary and at the discovery stage and requires validation in independent cohorts before its clinical relevance or utility can be determined.

推荐理由:聚焦孤立性ANA阳性这一易被忽视的不孕亚群,将卵泡液多组学与胚胎学结局关联,发现初步代谢标志物面板;但样本量较小、缺乏独立验证,结论宜作为假说生成阅读。

一句话结论:孤立性ANA阳性者卵泡液存在代谢重编程与早期胚胎发育受损,三者代谢物组合初步区分ANA状态(AUC 0.968)。

研究背景

自身免疫异常日益被认为是原因不明性不孕的致病因素之一,抗核抗体(antinuclear antibodies, ANA)是最常检出的自身抗体,并与不良胚胎学结局相关。孤立性ANA阳性指ANA阳性而抗可提取核抗原抗体(anti-ENA)阴性;此类状态如何影响卵母细胞发育潜能与早期胚胎发育,机制尚不清楚。本研究拟用整合多组学方法刻画与孤立性ANA阳性相关的卵泡液(follicular fluid, FF)分子改变,并探索其与卵母细胞及胚胎发育能力的关联。

研究设计与方法

前瞻性队列研究(prospective cohort study),纳入70例首次接受辅助生殖技术(ART)周期的不孕女性:32例孤立性ANA阳性(血清ANA ≥ 1:80且anti-ENA阴性)与38例ANA阴性对照。于取卵日采集卵泡液,进行代谢组与蛋白质组的整合分析(integrated metabolomic and proteomic analyses);随后做差异表达与功能富集分析,并进行相关性与网络分析以探索FF分子谱与卵母细胞/胚胎发育能力的关联;对关键代谢物采用ROC(receiver operating characteristic)分析评价探索性判别效能。具体组学平台、检测通量、质控与归一化方法,以及Figure/表格内容:原文未提供。

主要发现

多组学视角

研究为代谢组与蛋白质组的整合(具体平台与数据规模原文未提供),策略是先在FF中做差异表达,再以功能富集定位通路(类固醇激素合成、补体与凝血级联、氨基酸代谢、甘油磷脂代谢),最后以相关性与网络分析把分子层与表型层(受精率、优质胚胎数、囊胚数)连接起来。层间关系上,补体/凝血等免疫相关蛋白通路与氨基酸、甘油磷脂、类固醇激素相关代谢物改变同时出现,被概括为「免疫-代谢」改变;其中L-苯丙氨酸(氨基酸代谢)、SM(d18:1/16:0)(鞘脂/甘油磷脂相关代谢)与氢化可的松(类固醇激素相关)被选为连接胚胎发育潜能的关键代谢物节点。哪些蛋白与哪些代谢物直接构成网络模块、网络的具体拓扑参数:原文未提供。

意义

该研究把「血清自身抗体状态」与「卵泡液局部免疫-代谢微环境」以及「胚胎学结局」联系起来,为孤立性ANA阳性相关不孕提供了可检验的机制假说与候选分子线索。对ART实验室而言,提示取卵日FF的代谢/蛋白谱可能作为无创或微创的卵泡微环境读出,用于解释同一中心内受精率与优质胚胎率、囊胚率的个体差异。临床层面,其提出的探索性代谢物panel可作为未来预后模型开发的起点,但作者明确指出尚不能用于临床决策。
